RESUMEN

Background: Substance use and substance use disorders (SUD) are prevalent among college students. Information about the gap between substance use treatment need versus treatment receipt can guide efforts to increase service access. This study examined past-year DSM-5 SUD and receipt of treatment among US college students. Methods: Past-year DSM-5 SUD and treatment receipt were estimated among a sample of 6115 college students aged 16 and older and a comparison group of non-students from the 2021 National Survey on Drug Use and Health, weighted to be nationally representative. Among the college student sample, multiple logistic regression was used to identify factors associated with past-year SUD. Bivariate analyses were used to compare socio-demographic and substance use differences between college students who received treatment and those who had an SUD but did not receive treatment. Results: Weighted prevalence of past-year SUD among college students was 21.8 %. Only 4.6 % of students who had an SUD received treatment in any setting. Relative to non-students with SUD, proportionately fewer college students with SUD received treatment. Among college students, age, sex, past-year psychological distress, and past-year substance use were significantly associated with past-year SUD; and receipt of treatment differed significantly by age, insurance type, level of education, and enrollment status. College students who received treatment had greater prevalence of stimulant, opioid, tranquilizer, and poly-SUDs and more severe SUD symptomology than those who did not receive treatment. Conclusion: Additional efforts are needed to engage college students with SUDs in acceptable, evidence-based treatment services.

RESUMEN

INTRODUCTION: Mental health professionals, teachers, families, and public administrators are concerned about suicide rates among young people, particularly in the university context. For every ten college students worldwide, three attempt suicide in their lifetime, and two experience suicidal ideation. Reducing these rates requires interventions that recognize the problem in terms of risk factors and protective factors. OBJECTIVE: The general aim of the study was to map the protective factors for suicide among college students, as perceived by them, mental health professionals, and coordinators of undergraduate courses in a public university in the North of Brazil. METHODS: The study followed an exploratory, mixed-method design. Data were collected through interviews and the application of a questionnaire with 54 participants, including college students (n = 20), mental health professionals (n = 22), and course coordinators (n = 12). Data were analyzed using Content Analysis and simple descriptive statistics. RESULTS: The findings show that the protective factors for suicide most cited among the three groups were social support, strengthening of internal resources, institutional support, and finding meaning about the change to enter the university. Although the three audiences did not converge, the protective factors also frequently reported were psychological treatment, leisure activities, religious engagement, medical treatment, civic engagement, employability, opportunities for social ascension offered by the university, and quality family relationships. CONCLUSION: It is suggested that these protective factors are considered when formulating policies to promote mental health and suicide prevention in the university environment.

RESUMEN

The coronavirus disease (COVID-19) pandemic and associated infection control measures have introduced significant uncertainty, and the unbearable nature of this uncertainty has heightened the risk of mental health issues among college students. This study aimed to assess the impact of unbearable uncertainty during the COVID-19 pandemic on college students' depression and investigate the mediating role of coping strategies between unbearable uncertainty and depression. A cross-sectional survey was conducted with 714 Chinese university students using the Intolerance of Uncertainty Scale (IUS-12), Brief Coping Style Questionnaire, and Beck Depression Inventory (BDI-II). SPSS PROCESS was used for the partial correlation analyses and structural equation modeling. (1) Negative coping strategies were significantly positively correlated with intolerable uncertainty and depressive symptoms, while positive coping strategies were negatively correlated with both intolerable uncertainty and depressive symptoms. Intolerable uncertainty was significantly and positively correlated with depressive symptoms. (2) Intolerance to uncertainty significantly predicted depressive symptoms. Both negative and positive coping strategies played parallel mediating roles in the relationship between unbearable uncertainty and depressive symptoms among college students. This study found that coping strategies played a mediating role in the relationship between unbearable uncertainty and depression during the pandemic in 2019. Future research and interventions should focus on enhancing tolerance of uncertainty and promoting positive coping strategies.

RESUMEN

This research delves into the correlation between offline bullying and online unethical behavior among college students; and examines the potential mediating influences of anger rumination and perceived relative deprivation. The findings suggest that anger rumination, perceived relative deprivation, offline bullying, and online unethical behavior exhibit significant positive correlations with each other. Offline bullying is a strong predictor of online unethical behavior among college students, with the dual mediating effects of perceived relative deprivation and anger rumination on the relationship between offline bullying and online unethical behavior. This suggests that offline bullying directly influences college students' online unethical behavior and also influences it indirectly through anger rumination and perceived relative deprivation.

RESUMEN

INTRODUCTION: In recent decades, the topic of gender differences has become central to many areas of study, including medicine. The present study explored gender differences in empathy, gender role ideologies, and gender sensitivity among medical students, highlighting significant variations that can inform medical education and training programs. MATERIALS AND METHODS: The study involved 155 students (52.1% male; mean age: 22.68±2.48 years) from the Department of Medicine, Surgery, and Dentistry of the University of Salerno in Baronissi, Southern Italy. Participants completed two standardized scales: the Jefferson Scale of Empathy (JSE) to assess empathy, and the Nijmegen Gender Awareness in Medicine Scale (N-GAMS) to evaluate gender awareness. Six open-ended questions were also included in the gender-based violence representations. RESULTS: The ANOVA analysis reveals significant differences in scores between male and female students across the N-GAMS scales, indicating a strong role of gender in these variations. These findings suggest the necessity for further research to understand the contributing factors and inform targeted interventions in medical education. Additionally, there are significant differences in compassionate care (Factor 2) and walking in the patient's shoes (Factor 3), highlighting the substantial impact of gender on these latter aspects of empathy. CONCLUSIONS: These gender differences have significant implications for medical education. Training programs should be tailored to address the specific needs and characteristics of both male and female students. For example, encouraging male students to maintain their gender sensitivity while challenging traditional gender role ideologies can promote a more inclusive approach to patient care. For female students, fostering confidence in their compassionate care abilities and providing opportunities to express empathy in diverse ways can help overcome societal constraints.

RESUMEN

Background: Amidst the expansion of student enrollment in higher education, the well-being and retention rates of students have emerged as important concerns. Resilience, especially academic resilience, a multidimensional construct that can lead to academic success in adversity, is pivotal in enabling students to successfully cope with academic challenges. While the Academic Resilience Scale-30 (ARS-30) has been validated as an effective instrument in various languages, its applicability for Chinese students in higher education remains unexplored. Objective: This study aims to translate and validate the ARS-30 in Chinese, assessing its reliability and validity among Chinese college students in higher education. Methods: A convenience sample of 1,542 students participated in this study. The inventory included the demographic form, Chinese version of ARS-30 (C-ARS-30), 10-item Connor Davidson Resilience Scale (CD-RISC-10), and General Self-Efficacy Scale (GSES). The assessment of validity was conducted by analyzing content validity, construct validity, convergent and discriminant validity, as well as criterion-related validity. Construct validity was evaluated through Confirmatory Factor Analysis (CFA), Exploratory Factor Analysis (EFA) and Exploratory Structural Equation Modeling (ESEM). Reliability analysis was performed using Cronbach's alpha and test-retest reliability. Results: The C-ARS-30 demonstrated commendable content validity, with the CVI value of items ranging from 0.833 to 1.000, and a total scale CVI of 0.986. ESEM analysis revealed a solid four-factor structure, maintaining the scale's 30 items with excellent fit indices (χ2/df = 2.647, CFI = 0.937, TLI = 0.915, RMSEA = 0.057, SRMR = 0.027). The total score of C-ARS-30 exhibited positive correlations with the CD-RISC-10 (r = 0.542) and the GSES (r = 0.488). The scale demonstrated high internal consistency (Cronbach's α = 0.930) and test-retest reliability (0.794, p < 0.01). Conclusion: The C-ARS-30 is a reliable and valid instrument for assessing academic resilience among Chinese college students, offering a valuable tool for educational and psychological evaluations.

RESUMEN

Smartphone addiction, emerging from excessive use of smartphones, poses a challenge to inhibitory control functions within society. This research employed transcranial direct current stimulation (tDCS) as an intervention alongside the stop signal task (SST) to explore behavioral distinctions between individuals with smartphone addiction and a non-addicted control group, focusing on the efficacy of tDCS intervention. The participant cohort comprised 80 individuals, divided into an addiction group (39 participants, with 19 receiving active tDCS and 20 receiving sham tDCS) and a control group (41 participants, with 20 receiving active tDCS and 21 receiving sham tDCS), with anodal stimulation applied over the right dorsolateral prefrontal cortex (dlPFC) and cathodal placement over the left arm. The findings indicate that university students struggling with smartphone addiction exhibit reduced inhibitory control compared to their non-addicted peers, while maintaining similar levels of general cognitive control. Remarkably, tDCS interventions were observed to enhance inhibitory control in both groups. Although the improvement in the addiction group appeared more pronounced numerically than in the control group, no significant interaction with group was noted. However, a higher percentage of participants in the smartphone addiction (SA) group exhibited enhanced response inhibition under active tDCS. This study demonstrates the inhibitory control deficits in individuals addicted to smartphones and underscores the potential of tDCS in enhancing response inhibition. It provides a valuable reference for future tDCS research targeting smartphone addiction and highlights the importance of developing healthier smartphone usage habits.

RESUMEN

OBJECTIVE: To investigate the prevalence of hyperuricemia among freshmen enrolled in Beijing Sport University and to explore the influencing factors of hyperuricemia in the college population. METHODS: The study period was from September 2021 to February 2022.3372 freshmen of the class of 2021 from Beijing Sport University in Beijing were selected as the study subjects, and two blood uric acid tests were performed on non-same days to calculate the prevalence of the population and to explore the risk factors of hyperuricemia in the college student population using a case-control method.246 people were selected from the hyperuricemia patients of the population to be included in the case group by convenience sampling, and 211 people were selected from the non-hyperuricemia persons of the population to be included in the control group. They were included in the control group, underwent physical and laboratory examinations, and were retrospectively surveyed with questionnaires that included general information such as age, gender, specialty, place of birth, and diet related to hyperuricemia, awareness of hyperuricemia disease, physical activity level, and sleep. Statistical analysis was performed using chi-square analysis, one-way Logistic regression analysis, and multi-factor logistic regression analysis. RESULTS: The number of patients actually diagnosed with hyperuricemia by two blood uric acid tests on non-same days was 479, with a population prevalence rate of 14.21%. Among them, the number of males in the diseased population was 391(22.39%), and the number of females in the diseased population was 88(5.41%). A total of 457 subjects were enrolled in the case-control study, among them, 246 in the case group(218 males and 28 females, average age 19.74 years), 211 in the control group(177 males and 34 females, average age 19.93 years), and 247 in the case group, 211 in the control group, and 2 groups of subjects were included. A total of 211 subjects, and there was no significant difference between the 2 groups in terms of gender composition and age distribution. One-way logistic regression analysis showed that central obesity(OR=31.52, 95%CI 7.59-130.86), obesity(OR=2.59, 95%CI 1.20-5.58), overweight(OR=1.67, 95%CI 1.08-2.59), frequent consumption of fresh vegetables(OR=0.66, 95%CI 0.43-0.99), and drinking 1500-2000 mL of water per day(OR=0.63, 95%CI 0.41-0.95) were associated with hyperuricemia, and multifactorial Logistic regression analyses were performed to analyze the above factors, and finally central obesity(OR=32.05, 95%CI 7.65-134.20), BMI obesity(OR=3.22, 95%CI 1.44-7.20), and daily water intake of 1500-2000 mL(OR=0.60, 95%CI 0.37-0.95) were included in the model at the level of P=0.05. CONCLUSION: The current high prevalence of hyperuricemia in the college student population, which is more prevalent in male college students. Obesity and central obesity are risk factors for hyperuricemia in young college students, and daily water intake of 1500-2000 mL is a protective factor.

RESUMEN

BACKGROUND: Higher education students exhibit heightened sensitivity to environmental changes as they navigate the critical transition from adolescence to adulthood. The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to universities worldwide, exemplifying a crisis that profoundly affects the learning outcomes and psychological status of college students. Although it is known that campus lockdown has triggered dramatic changes in lifestyles, learning outcomes, and psychological statuses, in-depth knowledge of the causal relationships among these changes remains largely unclear. METHODS: Here, we conducted a cross-sectional survey designed to assess the impact of campus closure during COVID-19 on lifestyle, educational performance, and anxiety levels among college students. We surveyed over 3,500 junior college, undergraduate and graduate participants from 94 colleges/universities across 30 provinces, municipalities, and autonomous regions in China.We employed structural equation modeling (SEM) to explore the relationships between changes in lifestyle, educational performance, and levels of anxiety associated with campus open or closure regulations during the COVID-19 pandemic. RESULTS: Our results discovered that sleep duration, physical activity involvement, and social connections were crucial for sustaining students' learning outcomes and mental health. The shift to online learning and campus lockdown exacerbated stressors, contributing to heightened anxiety (ß = 0.066), disrupted sleep patterns, and enhanced physical activity (ß = 0.070) and reduced learning effect (ß = -0.059). Sleep patterns were disrupted by the campus lockdown, an effect mediated by the degradation of relationships among classmates. Nonetheless, the best-fitting SEM uncovered the intricate relationships among lifestyle changes, learning outcomes, and psychological status in response to sudden environmental changes (Fisher's C = 80.949, P = 0.328). These results highlight the critical role of adaptable, supportive campus policies tailored to meet the diverse needs and interests of students during and beyond crises (Fisher's C = 59.568, P = 0.809). CONCLUSIONS: Our study advocates for a holistic approach that addresses the multifaceted aspects of student life to cultivate a resilient academic community. This approach contributes to a deeper understanding of the effects of sudden environmental changes on students' psychological well-being and academic performance in the post-pandemic era.

RESUMEN

The Symptom Checklist-90 (SCL-90), widely utilized for psychological assessments, faces challenges due to its extensive nature. Streamlining the SCL-90 is essential in order to enhance its practicality without compromising its broad applicability across diverse settings. The objective of this study is to employ machine learning techniques to simplify the dimensions and individual items within each dimension, while simultaneously validating the accuracy and practicality of the streamlined SCL-90 scale. A total of 23,028 valid responses of the SCL-90 were obtained from university students, with positive cases accounting for 49.58 % and negative cases accounting for 50.42 %. The findings demonstrate that by utilizing the Support Vector Classification (SVC) algorithm, it is possible to reduce the scale from ten dimensions to four, achieving an overall prediction accuracy of 89.50 % for the total score. Further simplification of these remaining four dimensions resulted in a reduction from 44 to 29 items per dimension, yielding individual dimension accuracies exceeding 90 %, along with sensitivity and specificity levels surpassing 85 %, and the reliability coefficients consistently exceeded 0.8 across different algorithms. In conclusion, we successfully reduced the number of scale items from 90 to 29, resulting in a reduction of 67.78 % in overall assessment time while maintaining a high reliability coefficient of 0.95. Importantly, the streamlined scale demonstrated no significant decrease in assessment effectiveness. This refined version facilitates rapid comprehension of individuals' comprehensive mental health status and is well-suited for widespread application in experiential settings.

RESUMEN

BACKGROUND: This study addresses the nexus of stress, physical exercise, and internet addiction in college students, aiming to unravel their complex interactions. With prior research hinting at correlations, this study seeks deeper insights into the optimal exercise duration and the mediating role of physical activity in the stress-internet addiction relationship. METHODS: We examined 2892 Chinese college students, assessing psychosocial traits via established scales: the Chinese Internet Addiction Scale (CIAS-R), International Physical Activity Questionnaire (IPAQ), and DASS-21 for stress. We adopted a questionnaire survey method to collect data, and through convenience sampling, participants were selected. Analysis involved Structural Equation Model (SEM) and restricted cubic splines (RCS). RESULTS: Among participants, 22.0 % self-reported internet addiction symptoms. Notably, a non-linear correlation between moderate (MPA) and vigorous physical activity (VPA) and internet addiction was evident (P < 0.001), while light physical activity (LPA) showed no significant association (P = 0.182). MPA initially reduced internet addiction as activity hours increased, but its efficacy lessened after 0.8 h/day. Conversely, VPA's impact fluctuated, declining from 0 to 0.18 h/day, then stabilizing. SEM analysis highlighted VPA and MPA's partial mediation in the stress-internet addiction relationship. Specifically, the path coefficient from stress to MPA was -0.037 (P < 0.05), and the path coefficient from MPA to internet addiction was -0.056 (P < 0.01). Additionally, the path coefficient from stress to VPA was -0.067 (P < 0.001), and the path coefficient from VPA to internet addiction was -0.102 (P < 0.001). CONCLUSION: This study unveils the intricate interplay between physical activity, stress, and internet addiction among college students. With 22.0 % reporting addiction symptoms, urgent interventions tailored to promoting healthy physical activity levels are imperative to mitigate internet addiction risks. LIMITATIONS: The cross-sectional nature of our design precludes the establishment of causal relationships between psychological stress and internet addiction.

RESUMEN

BACKGROUND: There is evidence that anxiety and stress increased among college students during the COVID-19 pandemic. However, less is known about daily experiences of affect, worry, substance use behaviors, experiences of pleasure, concern over food security, experiences of bias or discrimination, feelings of belongingness, and other indicators of well-being and how they vary across days in this population. OBJECTIVE: This study surveyed a wide range of indicators of health and well-being in daily life over 21 days with a sample of college students in a large university system in the United States during the pandemic. The overall variance in each daily measure was partitioned to reflect the proportion due to (1) between-person differences versus (2) within-person, day-to-day variability. This is important because measures that vary primarily due to between-person differences may be more amenable to interventions that target particular students, whereas measures that vary more due to day-to-day variability may be more amenable to interventions that target day-level contextual factors. METHODS: A sample of 2068 young adult college students (aged 18-24, mean 19.8, SD 1.3 years; 66.6% women) completed a baseline survey; 97.3% (n=2012) then completed up to 21 consecutive daily surveys that assessed a comprehensive set of daily markers of health, behavior, and well-being. The daily diary study produced a total of 33,722 person-days. RESULTS: Among all person-days, a minority were substance use days (eg, 14.5% of days involved alcohol use, 5.6% vaping, and 5.5% cannabis). Experiences of pleasure were reported on most (73.5%) days. Between-person differences explained more than 50% of the variance in numerous indicators of health and well-being, including daily vaping, cannabis use, other illicit substance use, experiences of bias or discrimination, positive affect, negative affect, worry, food insecurity, and feelings of belonging at the university. In contrast, within-person differences explained more than 50% of the variance in daily alcohol use, cigarette use, stress, experiences of pleasure, where the student slept last night, and physical activity. CONCLUSIONS: College student health and well-being are multifaceted, with some aspects likely driven by person-level characteristics and experiences and other aspects by more dynamic, contextual risk factors that occur in daily life. These findings implicate services and interventions that should target individual students versus those that should target days on which students are at high risk for poor experiences or behaviors.

RESUMEN

Parasomnias are a group of sleep disorders characterized by abnormal and unpleasant motor, verbal, or behavioral events that occur during sleep or during transitions between wake and sleep states. They disrupt sleep and can have a detrimental impact on the individual experiencing them. Our goal was to identify types of parasomnias and their prevalence in the current and recent post-secondary student population and to explore their coping strategies for parasomnias they found distressing. Seventy-seven post-secondary students completed the 21-item Munich Parasomnia Screening (MUPS) frequency scale. They also rated, on a 10-point scale, how disturbing each parasomnia experienced was. Not only did 92% percent of students report at least one parasomnia, but our results also indicate that the vast majority of students experienced several parasomnias. This led us to investigate the likelihood of the co-occurrence of different parasomnias. With respect to the level of subjectively experienced distress, the most prevalent parasomnias were not always the more disturbing. Coded open-ended responses about what students do about the disturbing parasomnias indicate that grounding strategies (i.e., coping strategies that help manage distressing feelings) and physical manipulation of one's body were the most common, although most participants indicated that in spite of distress, they do nothing to cope. In conclusion, our study found a strikingly high prevalence of parasomnias in this sample of young adults and a lack of knowledge about effective means of dealing with these. Therefore, we provide some accepted ways of dealing with these.

RESUMEN

Objective: To evaluate the acceptability of and engagement with an undergraduate human physiology course embedded with mindfulness practice. To assess its preliminary efficacy on student mindfulness and wellbeing. Methods: Students (N = 36, 17% freshman, 33% sophomore, 22% junior, and 28% senior) answered online surveys at course completion. Primary outcomes were course ratings, assignment and assessment completion rates, minutes, types of mindfulness practice, changes in trait mindfulness (Mindful Attention Awareness Scale, MAAS), and self-reported wellbeing outcomes. We ran Chi-square goodness of fit tests and paired Wilcoxon signed-rank tests to decide if the outcomes differed significantly post-class. We tested the dose-response relation between mindfulness practice time and trait mindfulness and whether the out-of-class practice time was consistent across the weeks with generalized linear mixed-effect models. Results: All participants reported finding the course enjoyable and that they would recommend it to their friends. They practiced for an average of 66 (SD = 27) min per week in the class and 112 (SD = 59) min on their own. The most common out-of-class practices were mindful movements, sitting meditation, and breathing. Per self-reports, the course increased student understanding of specific mindfulness practices and appreciation for their body. It improved wellbeing and trait mindfulness (MAAS mean within-person change = 1.2, SD = 0.8, p < 0.00001). We found no does-response relation between practice time and trait mindfulness. Conclusions: This pilot study supports that incorporating mindfulness practice into college-level courses may promote student wellbeing and such approaches warrant further investigation.

RESUMEN

Background: Social anxiety has consistently emerged as a prominent manifestation of mental health issues among college students. Though the relationship between upward social comparison and social anxiety has been extensively addressed in previous literature, little attention has been paid to the underlying mechanisms at play. Objective: The present study used a questionnaire survey to test whether upward social comparison may be associated with social anxiety in Chinese college students. The mediating role of relative deprivation and rumination was also examined. Methods: In total, 463 college students were recruited to complete four scales, including the Upward Social Comparison Scale, the Relative Deprivation Scale, the Ruminative Thinking Scale, and the Social Anxiety Scale. Results: The results show that upward social comparison was significantly positively correlated with relative deprivation, rumination, and social anxiety (r = 0.30, 0.31, and 0.27, respectively; p < 0.01). Second, relative deprivation was positively correlated with rumination and social anxiety (r = 0.40 and 0.17, respectively; p < 0.01). Finally, rumination was positively correlated with social anxiety (r = 0.47, p < 0.01). Moreover, upward social comparison positively predicts social anxiety, with an effect value of 0.12, while rumination plays a mediating role between upward social comparison and social anxiety, with an effect value of 0.07, and the 95% confidence interval for the indirect effect is 0.04-0.11. Separately, the chain mediation of relative deprivation and rumination had an effect value of 0.03, and the 95% confidence interval for the indirect effect is 0.02-0.05. Conclusion: This research highlights the relationship between upward social comparison and social anxiety in Chinese society and revealed the mediating mechanisms between them, deepening our understanding of how upward social comparison increases social anxiety.

RESUMEN

Parent communication can be protective against cannabis use among young adults. However, changes in parent-student communication frequency naturally occur during the transition from high school to college. Recent research suggests declines in parent-student communication frequency predict increased drinking and consequences during the first year of college, yet these effects on other risky behaviors are unknown. The current study investigated whether post-matriculation changes in frequency of texting/calling with parents predict cannabis use and simultaneous use of cannabis and alcohol, and whether pre-matriculation cannabis and simultaneous use predict changes in communication. First-year students (N = 287, 61.3% female, 50.9% White) reported cannabis and simultaneous use pre- and post-matriculation (T1 & T3) and changes in frequency of texting/calling their mother/father per day (T2). Negative binomial hurdle models examined whether T2 changes in communication frequency predicted T3 cannabis and simultaneous use, and logistic regression models examined whether T1 cannabis and simultaneous use predicted T2 changes in communication frequency. Results revealed that increasing (vs. decreasing) frequency of calling with mothers and texting with fathers was protective against cannabis use, whereas increasing frequency of calling with fathers was associated with greater risk of use. Changes in communication did not significantly predict simultaneous use, nor did pre-matriculation cannabis or simultaneous use predict changes in either mode of communication with parents during the college transition. These findings highlight that changes in mother and father communication may be both beneficial and detrimental to cannabis use depending on the parent and mode of communication. Implications for these findings are discussed.

RESUMEN

Objective: To explore the relationship among boredom proneness, the behavioral inhibition system, and anxiety among college students based on variable-centered and person-centered analytic approaches. Methods: A questionnaire survey was conducted on 1,102 college students from a university in Hebei Province using the Boredom Proneness Questionnaire (BPQ) for College Students, the Behavioral Inhibition System Scale (BIS), and the General Anxiety Disorder-7 scale (GAD-7). Results: The results reveal that boredom proneness was negatively correlated with scores on the behavioral inhibition system (r = -0.100, p < 0.01), and positively correlated with anxiety (r = 0.457, p < 0.001), while the behavioral inhibition system was positively correlated with anxiety (r = 0.086, p < 0.01). In the variable-centered analyses study, it was found that the behavioral inhibition system partially mediated the association between boredom proneness and anxiety. In the person-centered analyses study, three subtypes were identified: the high boredom-low inhibition group (9.35%), the moderate boredom-inhibition group (66.70%), and the low boredom-high inhibition group (23.95%). Individuals in these subtypes showed significant differences in anxiety scores (F = 4.538, p < 0.05), with the low boredom-high inhibition group scoring the highest. Conclusion: The results showed that the behavioral inhibition system partially mediates the relationship between boredom proneness and anxiety in college students; boredom proneness and the behavioral inhibition system exhibit group heterogeneity, with distinct classification features closely related to anxiety.

RESUMEN

BACKGROUND: The family environment has a significant influence on the personality development of young people and their assessment of life satisfaction. Perceived stress is related to life satisfaction, but this relationship is also influenced by the family context. The present study analysed the impact of perceived stress on life satisfaction and the mediating role of family climate in university students. METHODS: A sample of 920 university students was recruited for this study. The instruments used included the Perceived Stress Scale, the Satisfaction with Life Scale, and the Family Social Climate Scale, and socioeducational information was collected. RESULTS: The results indicate that perceived stress had a significant and positive effect on both conflictive and violent family climates, while life satisfaction was negatively impacted by these negative family climates. Additionally, supportive and cohesive family climates, along with difficulty expressing feelings and opinions, were found to have significant positive effects on life satisfaction. CONCLUSIONS: These findings highlight the importance of the family system in shaping individual conditions and how it can regulate the relationship between stress and life satisfaction.

RESUMEN

BACKGROUND: To evaluate the effects of booster and no booster versions of web-based alcohol Personalised Normative Feedback (PNF) and whether descriptive norms mediated and/or participant motivation moderated the effectiveness of the intervention in real world conditions (i.e. no financial incentives). METHODS: Pragmatic randomised controlled trial with 1-, 3-, and 6-month assessments. Brazilian college students reporting alcohol use in the last 12 months (N=931) were recruited from May/2020 to December/2022 and allocated to 1) No booster/single PNF(S-PNF); 2) Booster/multiple PNF(M-PNF); or 3) Assessment-only control. We applied Helmert coding [1: Any intervention (S-PNF or M-PNF) vs. Control; and 2: S-PNF vs. M-PNF]. PRIMARY OUTCOMES: typical number of drinks/week and maximum number of drinks/week; secondary outcomes: drinking frequency and number of consequences. Three-months assessment was the primary interval. Descriptive norms were tested as mediator. Interest, importance, and readiness to change were examined as moderators. RESULTS: Compared to control, any intervention did not influence primary outcomes at 3-months or 6-months, but did at 1-month, when reduced typical drinking (IRR:0.77, 95%CI:0.66;0.90) and maximum number of drinks (IRR:0.69, 95%CI:0.58;0.82). There was an intervention effect on the consequences at 3-months. No differences were observed between S-PNF and M-PNF. No mediation effects were found at 3-months. At 6-months, there was an indirect effect on typical drinking through norms at 3-months (b=-0.82, 95%CI:-2.03;-0.12) and effects on maximum drinks through norms at 1-month (b=-0.54, 95%CI:-1.65;-0.02). No support for moderation was found. CONCLUSIONS: Intervention reduced alcohol drinking at 1 month only and was not effective thereafter. Mechanisms of effect remain unclear.

RESUMEN

Background: The spread of Covid-19 and resultant infection prevention strategies have disturbed the life routine of Chinese young adults, led to reduced physical activity (PA), prolonged screen time (ST) and inadequate sleep duration (SP), and made immense influence on their mental health (MH) and quality of life (QoL). E-Health literacy (EHL) can enable citizens to use available online information to respond to the highly complex information environment and make appropriate health decisions. Objective: This study aims to examine associations between adhering to 24-h movement (24HM) guidelines and MH and QoL among young adults, as well as to identify any mediating or moderating role of EHL in these associations. Methods: 1742 young adults (20.03 ± 1.54 years old, 68.6% females) from north and south China completed self-report measures of 24HM (PA, ST and SP), health indicators (MH and QoL), EHL and demographic information through an online survey between 4 Apr and 16 Jun 2022. Generalized linear mixed models were applied for data analysis. Results: Results showed that adhering to PA, ST and SP guidelines were all positively connected with QoL while MH was associated with adhering ST or SP guidelines. Adhering to more of 24HM guidelines was linked to better MH and QoL. EHL significantly mediated the association of guideline adherence and QoL and moderate that of guideline adherence and MH. Conclusion: This is the first study to investigate the role of EHL on the associations between 24HM and MH as well as QoL during the Covid-19. The findings may contribute to further empirical research or intervention that aims to promote MH or QoL among young adults more effectively or provide valuable references for developing relevant strategies or policy of health promotion or public health events in China.
