RESUMEN

A substantial body of research indicates that higher education students from lower social class backgrounds tend to have poorer health than those from higher social class backgrounds. To investigate sleep as a potential mediator of this relationship, online survey responses of students from five large Australian universities, one Irish university and one large Australian technical college were analysed in three studies (Study 1 N = 628; Study 2 N = 376; Study 3 N = 446). The results revealed that sleep quality, sleep duration, sleep disturbances, pre-sleep worries and sleep schedule variability mediated the relationship between social class and physical and mental health. Sleep remained a significant mediator when controlling for related variables and other mediators. Thus, the findings suggest that sleep partly explains social class differences in health. We discuss the importance of addressing sleep issues among students from lower social class backgrounds.

RESUMEN

INTRODUCTION: Restrained, emotional and intuitive eating were examined in relation to each other and as correlates of participants' weight status, body image and self-esteem. In some past research, restrained and emotional eating have been associated with higher weight status and poorer mental health, while intuitive eating is more frequently linked to lower weight status and more positive well-being. However, these eating styles have rarely been examined together and never in a large cross-country sample. METHOD: Six-thousand two-hundred and seventy-two (6272) emerging adults (M age = 21.54 years, SD = 3.13) completed scales from the Three-Factor Eating Questionnaire, the Eating Disorders Examination Questionnaire, the Intuitive Eating Scale-2, the Multidimensional Body Self Relations Questionnaire, the Rosenberg Self-Esteem Scale, and provided weight and height information that was used to calculate body mass index (BMI). Participants resided in Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States and provided information using an online survey. RESULTS: Path analyses for the entire sample revealed significant pathways between higher intuitive eating and higher body satisfaction and self-esteem, and lower BMIs among participants. Higher levels of restrained and emotional eating were associated with lower body satisfaction and self-esteem, and higher BMIs among participants. Minor cross-country differences were evident in these patterns of relations, but intuitive eating emerged as a consistent predictor across countries. CONCLUSION: Overall, findings suggest that efforts should be made to increase intuitive eating among emerging adults and to support individual and macrolevel interventions to decrease restrained and emotional eating behaviours.

RESUMEN

Although a range of risk factors have been identified for disordered eating and weight status, the breadth of risk factors have been rarely considered within a single, comprehensive model. The robustness of these findings across countries also remains an open question. The present study sampled 6272 participants aged 18-30 years from eight countries in an attempt to evaluate combined and unique predictors for these two conditions, and to explore possible cross-country differences in these models. Participants completed a range of demographic, biological, behavioral, psychological, and sociocultural measures to test a comprehensive model of the contributions of these predictors for disordered eating and weight-related constructs (binge eating, body mass index, compensatory behaviors, dietary restraint, drive for muscularity, and drive for leanness). Structural invariance testing within a multigroup path analysis framework revealed that a single model across the eight countries provided poor model fit. Freeing of 22% of parameters across countries provided excellent fit and a satisfactory compromise for country-invariant and country-variant parameters in the model. Overall, predictors accounted for between 15% and 60% of variance in the outcome measures, with lowest explained variance for the disordered eating outcomes. Significant unique contributions to prediction were observed for each of the five risk factor variable types and across the eight countries. Thus, the findings show strong support for this model as an explanatory framework of both disordered eating and weight status.

RESUMEN

Background and Objectives: Health anxiety is one of the most common problems in patients with coronary artery disease. The present study tested whether health anxiety severity could be predicted by spiritual well-being and hope in patients with advanced coronary artery disease. Materials and Methods: In a cross-sectional study, 100 patients with advanced coronary artery disease were recruited from hospitals and healthcare centers in Iran. Patients completed self-report scales, including the Spiritual Well-Being Scale, Adult Hope Scale, and Short Health Anxiety Inventory. Hierarchical multiple regression analyses were used to empirically explore the relations among variables. Results: Results indicated that patients who reported higher levels of hope (ß = 0.42, p < 0.01) and spiritual well-being (ß = 0.20, p < 0.05) reported lower levels of health anxiety. Agency (ß = 0.58, p < 0.01) scores were a significant negative predictor of health anxiety severity. Additionally, religious spirituality scores (ß = 0.28, p < 0.01) were shown to significantly negatively predict health anxiety level. However, the pathways components of hope and existential spirituality were not significant predictors. Conclusion: The findings of the present study indicate that spiritual well-being and hope could be important factors in determining health anxiety for adults with coronary artery disease, and their role is worthy of further exploration to help improve health anxiety for patients with coronary artery disease.

RESUMEN

ABSTRACT: Research has shown that women are more prone to childhood trauma and this state is associated with somatic symptoms. Also, people who have been exposed to traumatic experiences use experiential avoidance to reduce negative emotions. However, the mediating role of experiential avoidance in the relationship between childhood trauma and somatic symptoms is not clear, so, the present study investigated whether the relationships among different types of childhood trauma and somatic symptoms could be explained by experiential avoidance in female college students. In a cross-sectional study, 251 Iranian female college students with somatic symptoms were recruited from the University of Tabriz. Participants completed self-report scales, including the Persian version of Child Abuse Self-Reported Scale, Acceptance and Action Questionnaire-II (AAQ-II), and the Patient-health questionnaire (PHQ-15). A path analysis was used to empirically explore the relationships. Structural equation modeling analyses confirmed a partial mediation model. Study participants who had a higher level of emotional trauma reported higher levels of somatic symptoms. Emotional and neglect trauma showed significant positive relations with experiential avoidance. Bootstrapping results showed that experiential avoidance partially mediated the relationship between emotional trauma and somatic symptoms. Moreover, the association between neglect and somatic symptoms was fully mediated by experiential avoidance. These findings suggest that experiential avoidance might be one mechanism explaining how adverse emotional and neglect experiences influence somatic symptoms. Interventions addressing experiential avoidance through methods such as emotion-focused therapy and mindfulness are discussed as potential future directions for treating somatic symptoms in females who experienced emotional and neglect trauma.

RESUMEN

This study examined the measurement invariance of three scales that assessed emotional eating, restrained eating, and intuitive eating across eight countries (Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States) in order to determine their suitability for cross-country body image research. A total of 6272 young adults took part in this study. Participants completed an online survey including the Emotional Eating subscale of the Three Factor Eating Questionnaire-Revised 21, the Restraint subscale of the Eating Disorder Examination Questionnaire, and the Reliance on Hunger and Satiety Cues subscale of The Intuitive Eating Scale-2. Multi-group confirmatory factor analysis was used to evaluate potential cross-country differences in functioning of the measures. Partial invariance for all three scales was found, with only minor levels of non-invariance identified. Multiple indicator multiple cause models identified BMI and gender as potential influences on scores for these measures. Sources of invariance across groups are discussed, as well as implications for further substantive research across countries involving these measures.

RESUMEN

PURPOSE: Fatigue is a physical and emotional state associated with certain aspects of nursing practice. The current study aimed to investigate the indirect effect of dispositional mindfulness on fatigue via emotional suppression in oncology female nurses. METHODS: In a cross-sectional study, 137 female oncology nurses were recruited from several hospitals to complete baseline questionnaires. Emotional suppression, dispositional mindfulness and fatigue were assessed with the Weinberger Adjustment Inventory (WAI), Five Facet Mindfulness Questionnaire (FFMQ) and the Multidimensional Fatigue Inventory (MFI) respectively. A Mediation model was tested using structural equation modelling. FINDINGS: Dispositional mindfulness was negatively associated with emotional suppression (ß = -0.69, p = 0.000). In addition, emotional suppression was positively associated with fatigue (ß = 0.32, p = 0.014). The mediation path was significant with emotional suppression fully mediating the relationship between dispositional mindfulness and fatigue (b = -0.20 [CI: -0.01, -0.25]. DISCUSSION: These results support the proposed model, and the assumption that emotional suppression may help facilitate the onset of fatigue or maintain it in female oncology nurses. The findings have implications for the use of brief mindfulness interventions aimed at the effective regulation of emotion in oncology nurses to aid in well-being and optimal nursing practice.

RESUMEN

BACKGROUND: The Aim of the study was to examine obesity health-related quality of life and body image satisfaction in a group of individuals having undergone bariatric surgery. METHODS: One hundred and forty-two persons who had undergone bariatric surgery answered an online survey which included measures of well-being and body image. The Multidimensional Body Self-Relations Questionnaire-Appearance Scales (MBSRQ-AS 34) was used to assess body image in relation to appearance evaluation (AE), appearance orientation (AO), overweight preoccupation (OP), self-classified weight (SCW), and body areas satisfaction (BASS). Obesity-related quality of life was assessed with the obesity related well-being scale (Orwell 97). RESULTS: Hierarchical multiple regression indicated that 50.2% of the variance in well-being post-surgery was explained by body image variables [F(6,84) =18.54, P<0.01], with the strongest predictor being satisfaction with body areas (B=-0.360, P<0.01). Regression analysis of the data for the group of patients who had received the vertical sleeve surgery was also significant, [F(6,56) =10.16, P<0.001] with satisfaction with different body areas being the best predictor of well-being (B=-0.365, P<0.05), followed by OP (B=0.313, P<0.05) and SCW (B=0.281, P<0.05). CONCLUSIONS: Body image concerns are more important predictors for well-being post bariatric surgery than weight lost. Psychological factors such as the perception of body areas, continued weight preoccupation and SCW rather an objective weight were better predictors of well-being, symptoms that impacted on well-being and on the subjective relevance of the symptoms to well-being. Recommendations for the translation of the present research findings for the surgical preparation of the bariatric patient and for post-surgery care are suggested.

RESUMEN

Bariatric surgery research has focused predominantly on weight loss outcomes and complications of surgery in relation to the type of surgical procedure. The psychological impact of having bariatric surgery has received less attention. This study investigated whether patients who receive psychological counselling have better physical and mental well-being post-bariatric surgery. Eighty-eight persons (81 female, 7 male, M age 43.99 years) who had undergone weight loss surgery were recruited from bariatric surgery and obesity online support groups to answer an electronic survey which included the Health Survey Short Form (SF-12) to assess mental and physical well-being. Patients who had attended ≥ 6 counselling sessions after gastric sleeve surgery had better physical well-being, compared to those who attended < 6 sessions. Patients who attended between one and four psychological counselling sessions had significantly higher mental well-being. Psychological support for the mental health needs of obese patients post-surgery requires more attention.

RESUMEN

BACKGROUND: This study investigated the expectations and experiences of a sample of new patients visiting an Australian regional university Student Dental Clinic with regard to anxiety provoking and alleviating stimuli in the clinical environment. Differences in anxiety levels were examined by age, gender and the type of procedure undergone. METHODS: The number of dental patients who participated in the study was 102 (56 males, 43 females). The study used a pre-treatment/post-treatment design to assess the effect of the dental procedure on anxiety levels of patients. The Modified Dental Anxiety Scale (MDAS) was used to measure anxiety levels in patients at pre-treatment. Questions were also asked about factors which may increase (length of the appointment, invasiveness of procedure) or decrease (perceived student interpersonal skills and clinical ability) dental fear. RESULTS: Females reported higher total MDAS scores (M = 11.93) compared to males (M = 9.94). Younger patients (M = 12.15) had higher dental anxiety than older patients (M = 9.34). There was a reduction in dental anxiety from pre-treatment (M = 1.92) to post-treatment (M = 1.23) on the single item anxiety measure though most of the treatment being undergone by patients was for less complex procedures. CONCLUSIONS: Patients' anticipatory experience of anxiety was higher than the anxiety experience after having undergone treatment at the student dental clinic. Student interpersonal skills and clinical ability as perceived by the patient can lessen dental anxiety in patients. Clinical Supervisor-student ratios need to be more equivalent in order to reduce the time length of appointments which currently are associated with increased patient anxiety levels in student dental clinics.

RESUMEN

PURPOSE: We investigated whether perfectionism, body image, attachment style, and self-esteem are predictors of orthorexia nervosa. METHODS: A cohort of 220 participants completed a self-administered, online questionnaire consisting of five measures: ORTO-15, the Multidimensional Perfectionism Scale (MPS), the Multidimensional Body-Self Relations Questionnaire-Appearance Scale (MBSRQ-AS), the Relationship Scales Questionnaire (RSQ), and Rosenberg's Self-Esteem Scale (RSES). RESULTS: Correlation analysis revealed that higher orthorexic tendencies significantly correlated with higher scores for perfectionism (self-oriented, others-oriented and socially prescribed), appearance orientation, overweight preoccupation, self-classified weight, and fearful and dismissing attachment styles. Higher orthorexic tendencies also correlated with lower scores for body areas satisfaction and a secure attachment style. There was no significant correlation between orthorexia nervosa and self-esteem. Multiple linear regression analysis revealed that overweight preoccupation, appearance orientation and the presence of an eating disorder history were significant predictors of orthorexia nervosa with a history of an eating disorder being the strongest predictor. CONCLUSIONS: Orthorexia nervosa shares similarities with anorexia nervosa and bulimia nervosa with regards to perfectionism, body image attitudes, and attachment style. In addition, a history of an eating disorder strongly predicts orthorexia nervosa. These findings suggest that these disorders might be on the same spectrum of disordered eating.

RESUMEN

This study developed a new scale, The Medical Social Self-efficacy Scale (MSSES), to assess social self-efficacy within a medical context for patients of diverse cultural and linguistic backgrounds. Validation of the MSSES with a sample of 113 persons indicated that the scale has good internal consistency, with a Cronbach's alpha coefficient of .85. A factor analysis yielded two factors (confidence in seeking medical information, confidence in stating my view) which accounted for 64% of the total variance. Split-half reliability of the MSSES was .84. Predictive validity of the MSSES and its factorial structure was found for the mental component summary and general health subscale of the 12-item Short-Form Health Survey. Evidence of concurrent validity was found with the active coping, planning and positive reframing subscales of the Brief COPE. Concurrent validity was also found for the MSSES and its factors, in regard to the emotion-focused coping composite subscale of the Brief COPE. The results indicate that the MSSES appears to be a psychometrically sound instrument.

RESUMEN

The role of resilience, for adults facing ongoing adversity in the form of chronic medical conditions, has received little attention in the past. This research investigated the impact of resilience and coping strategies on the psychological functioning of 87 Australian adults with chronic pain, using a self-report questionnaire. It included the McGill Pain Questionnaire, the Connor-Davidson Resilience Scale, the Coping Strategies Questionnaire, the 36-item Short Form Health Survey, and the Depression, Anxiety and Stress Scale. Using hierarchical regression, after the effects of pain severity, catastrophizing, and ignoring the pain were controlled for, resilience was significantly associated with mental health-related quality of life (ß = 0.18, P < 0.05), depression (ß = -0.31, P < 0.01), and anxiety (ß = -0.20, P < 0.05). In the final model for depression, resilience had a stronger association than pain severity. Resilience did not, however, influence individual's perceptions of their physical health-related quality of life. The link between resilience and mental health-related quality of life outcomes provides initial evidence for the potential application of resilience related interventions to pain management programs.
