RESUMO

Objective: Analyse the psychometric properties of the Portuguese version of the PAFAS (Parenting and Family Adjustment Scales) parenting scale, using data from two large Brazilian birth cohorts. Methods: The original PAFAS parenting scale, which consists of 18 items (parental inconsistency 5 items, coercive parenting 5 items, positive encouragement 3 items, and parent-child relationship 5 items) was applied in two Brazilian birth cohorts in Pelotas (ages 4 [n = 4010] and 6-7 [n = 3867]) and Rio Grande (age 3 [n = 992]). Confirmatory factor analysis was conducted, and internal consistency assessed, as well as construct validity in relation to maternal depression measured on the Edinburgh Postnatal Depression Scale. Results: The model with a structure of 4 subscales showed that the global scale of parenting on the PAFAS had a good fit, but certain items did not fit well on sub-scales and were removed (2 items from parental inconsistency, 1 from coercive parenting, and 1 from positive encouragement). The original form of the parent-child relationship sub-scale was maintained. Considering the total PAFAS parenting score, we found that mothers with maternal depression had a higher likelihood of more problematic parental practices than mothers without depression. Conclusions: A revised 14-item PAFAS parenting scale has good psychometric properties and we encourage its use in Brazilian populations.

RESUMO

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.

RESUMO

Abstract The condom use can be influenced by psychological and sociocultural aspects, which can be modulated by individual's attitudes. The aim was to propose a Brazilian Portuguese version of the Short-Form Condom Attitude Scale (Short-Form CAS), describing all procedures of translation, transcultural adaptation, and psychometric properties evaluation when applied to undergraduate students. A cross sectional study was conducted among students enrolled at University of São Paulo (USP), Campus Ribeirão Preto (n = 491; 61.2% female; average age: 22 years; standard deviation: four years). Confirmatory factor analysis was performed. A one-factor model with seven items exhibited good factorial validity and reliability, suggesting to be a better factorial solution of the Short-Form CAS in the sample. Few studies have been carried out on the behavioral factors associated with condom use in key populations, which can be exacerbated by a lack of appropriate scales. Therefore, the main contribution of the present study was to propose a simplified and transculturally adapted version of the Short-form CAS with some psychometric properties verified. Since the use of condoms is a component of the study of sexual risk behavior, this scale might be an option to be applied in various Brazilian population segments for this purpose.

Resumo O uso de preservativos pode ser influenciado por aspectos psicológicos e socioculturais, que podem ser modulados por atitudes individuais. O objetivo foi propor uma versão em português brasileiro da Short-Form Condom Attitude Scale (Short-Form CAS), descrevendo os procedimentos de tradução, adaptação transcultural e avaliação das propriedades psicométricas em uma amostra de universitários. Trata-se de estudo transversal com estudantes matriculados na Universidade de São Paulo (USP), Campus Ribeirão Preto (n = 491; 61,2% feminino; média de idade: 22 anos; desvio-padrão: quatro anos). Foi realizada análise fatorial confirmatória. O modelo unifatorial com sete itens apresentou boa validade fatorial e confiabilidade, sugerindo ser a melhor solução fatorial para a Short-Form CAS. Há poucos estudos sobre os fatores comportamentais associados ao uso de preservativos em populações-chave, o que pode ser influenciado pela falta de instrumentos. A principal contribuição deste estudo foi propor uma versão simples e adaptada transculturalmente da Short-Form CAS com algumas propriedades psicométricas verificadas. Uma vez que o uso de preservativos é um componente do comportamento sexual de risco, a escala se apresenta como uma nova opção para futuros estudos na população brasileira.

RESUMO

Understanding the genotype-by-environment interaction (GEI) and considering it in the selection process is a sine qua non condition for the expansion of Brazilian eucalyptus silviculture. This study's objective is to select high-performance and stable eucalyptus clones based on a novel selection index that considers the Factor Analytic Selection Tools (FAST) and the clone's reliability. The investigation explores the nuances interplay of GEI and extends its insights by scrutinizing the relationship between latent factors and real environmental features. The analysis, conducted across seven trials in five Brazilian states involving 78 clones, employs FAST. The clonal selection was performed using an extended FAST index weighted by the clone's reliability. Further insights about GEI emerge from the integration of factor loadings with 25 environmental features through a principal component analysis. Ten clones, distinguished by high performance, stability, and reliability, have been selected across the target population of environments. The environmental features most closely associated with factor loadings, encompassing air temperature, radiation, and soil characteristics, emerge as pivotal drivers of GEI within this dataset. This study contributes insights to eucalyptus breeders, equipping them to enhance decision-making by harnessing a holistic understanding-from the genotypes under evaluation to the diverse environments anticipated in commercial plantations.

RESUMO

OBJECTIVE: To test the reliability and validity of the Chinese version of the Child-to-parent Violence Questionnaire (CPV-Q) in a group of Chinese adolescents. METHODS: A total of 1138 adolescents (15.24 ± 1.17 years old) were tested with the Chinese version of CPV-Q, Parent-Adolescent Conflict Scale, and Adolescent Aggressive Behavior Scale of which 201 adolescents were retested 1 month later. The Chinese version of CPV-Q contains psychological, physical, financial, and control/domain factors with 14 items. RESULTS: The four-factor model has good main fit indicators (father: χ2/df = 3.28, CFI = 0.96, RMSEA = 0.06; mother: χ2/df = 3.30, CFI = 0.96, RMSEA = 0.06); the scale has good criterion-related validity. The Cronbach's α coefficients of the Chinese version of CPV-Q were 0.89 (father) and 0.88 (mother), and the Cronbach's α coefficients of the four subscales were 0.81 ~ 0.84 (father) and 0.76 ~ 0.85 (mother). The test-retest reliability of the Chinese version of CPV-Q was 0.85 (father) and 0.83 (mother), and the test-retest reliability of the four subscales was 0.80 ~ 0.83 (father) and 0.75 ~ 0.84 (mother). CONCLUSION: Therefore, the CPV-Q has good reliability and validity for Chinese adolescents and can be used as an effective tool to evaluate Chinese adolescents' violence toward their parents.

RESUMO

BACKGROUND: The Primary Sjögren's Syndrome Quality of Life questionnaire (PSS-QoL) is the first specific instrument to assess health-related quality of life (HRQoL) in Sjögren's disease (SjD). The aim is to translate and cross-culturally adapt the PSS-QoL into Brazilian Portuguese and to evaluate its psychometric properties. METHODS: The original English version was translated into Brazilian Portuguese by two native Brazilians who were proficient in the English language. The retranslation was conducted by two native Americans proficient in Brazilian Portuguese. A committee undertook an analysis of the translated and retranslated versions, resulting in the generation of the first Brazilian version, which was submitted to the cross-cultural adaptation phase. In this phase, 50 participants with SjD responded to the instrument in Stages I and II, resulting in the generation of the second and final Brazilian version. To assess the psychometric properties, demographic and clinical data were collected from 75 patients. The HRQoL questionnaires (final Brazilian version of the PSS-QoL, Short Form-36 Health Survey (SF-36) and EuroQoL-5 dimension (EQ-5D)) were completed. Construct validity was analyzed using the Pearson or Spearman correlation coefficient. Reliability was analyzed using Cronbach's alpha and the intraclass correlation coefficient (ICC). RESULTS: Eight questions and one response item were revised due to an incomprehension rate of greater than 15% among the participants in the cross-cultural adaptation phase. The final Brazilian version of the PSS-QoL was validated, revealing a high correlation between the total score and functional capacity (r= -0.713, p < 0.001), and vitality (r= -0.770, p < 0. 001) and mental health (r= -0.742, p < 0.001) domains of the SF-36 and a moderate correlation with the other domains of the SF-36 and a moderate correlation with the EQ-5D-tto (r= -0.573, p < 0.001), and EQ-5D-VAS (r= -0.559, p < 0.001). The intraobserver (ICC = 0.939; Cronbach's alpha = 0.964) and interobserver (ICC = 0.965; Cronbach's alpha = 0.964) reliability of the total score showed very high consistency. CONCLUSION: The Brazilian version of the PSS-QoL has been demonstrated to be a valid and reproducible instrument for the assessment of HRQoL in patients with SjD.

RESUMO

The objective of this study was to evaluate the reliability of Modified Vector Coding in assessing the coordination and coordination variability of the lower limbs and pelvis during running and to determine the Minimal Detectable Change (MDC). Twenty-five healthy runners participated in a biomechanical analysis of treadmill running using a motion capture system. Modified vector coding was applied to assess the three-dimensional coordination among various pelvis and lower limb segmental couplings. Reliability was assessed using the Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), MDC, and Bland-Altman analysis to ascertain measurement consistency, agreement, and the smallest clinically meaningful change that exceeds measurement error. The test-retest reliability for 33 of 42 segmental couplings analyzed was good to excellent, with ICC values ranging from 0.613 to 0.928 (p <0.05), which substantiates the robustness of modified vector coding in running biomechanics. However, nine couplings, particularly femur-tibia in the sagittal plane during midstance and foot in the frontal plane-tibia in the transverse plane during late stance, exhibited poor to moderate reliability. These findings underscore the need for cautious interpretation due to significant proportional bias (p <0.05). SEM and MDC provided insights into the precision and minimal clinically significant changes for each coupling. The findings confirm the reliability of modified vector coding for biomechanical analysis in running, with most couplings demonstrating consistent high reliability. Nevertheless, specific couplings should be interpreted with caution due to potential measurement errors. The application of MDC highlights the precision of modified vector coding in biomechanical analyses and emphasizes the importance of careful interpretation to improve clinical and research outcomes in running-related injuries.

RESUMO

Breast cancer is the most common cancer in women worldwide, and its treatment usually involves a combination of many medical procedures, including surgery, chemotherapy, radiotherapy, and hormonal therapy. One of the detrimental effects on physical function is reduced upper limb muscle strength. This study aimed to evaluate upper body strength intra-day and inter-day (test-retest) reliability using the handgrip strength test (HGS) and the bilateral isometric bench press (BIBP) and the test-retest reliability of the one repetition maximum on the bench press (BP-1RM) in breast cancer survivors (BCS). Thirty-two (52.94 ± 8.99 yrs) BCS participated in this study. The muscle strength tests were performed in two different moments, three to seven days apart. Intraclass coefficient correlation (ICC) and coefficient of variation (CV) were used to assess the reliability. Standard error of measurement (SEM), typical error of measurement (TEM), and minimally detectable change (MDC) analyses were performed. The Bland-Altman analysis was used to assess the agreement between test-retest. We found a reliability that can be described as "high" to "very high" (ICC ≥ 0.88; CV ≤ 10%) for intra-day and test-retest. SEM% and MDC% were lower than 5% and 11%, respectively, for all intra-day testing. SEM% and TEM% ranged from 3% to 11%, and MDC% ranged from 9% to 23% in the test-retest reliability. The agreement demonstrated a systematic bias ranging from 2.3% to 6.0% for all testing, and a lower systematic bias may be presented in the non-treated side assessed by HGS and BIBP. HGS, BIBP, and BP-1RM assessments are reliable for measuring upper-body muscle strength in BCS.

RESUMO

OBJECTIVE: Perform the validation and psychometric evaluation of the Brazilian-Portuguese translation of the Functional Outcome of Sleep Questionnaire 10 (FOSQ10). MATERIALS AND METHODS: 182 patients (65 females 48.3±14.4 years and 117 males 46.9±12.4 years), were evaluated by sleep physicians suspected of having Obstructive Sleep Apnea, underwent polysomnography and completed the FOSQ-10 and the Epworth Sleepiness Scale. APA & NCME, 2014 was used to validate the data as the American Educational Research Association recommended. RESULTS: Quality indicators such as Bartlett's test of sphericity (χ2 = 1108.2; gL=45; p= 0.000010) and KMO (0.83), and adherence measures, attest to the quality of the model. The indicators TLI (0.97), CFI (0.98), and RMSEA (0.04) fall within the expected values. Using the Eigenvalue > 1 technique, two factors explain 53% and 13.3% of the variances. In the Parallel Analysis technique, a single factor explained 59.4653% of the random variance, and the Unidimensionality indicators UniCo = 0.921, ECV = 0.822, and MIREAL = 0.253, were supported. Construct Validity: reliability coefficients Cronbach's α = 0.87, McDonald's ordinal Omega index 0.9, and the Composite Reliability 0.891 were satisfactory. CONVERGENT VALIDITY: There was a significant Spearman correlation between FOSQ-10 and the Epworth Sleepiness Scale (r = 0.364 [-0.487; -0.226]). CRITERION VALIDITY: Was not possible to differentiate the groups based on the severity of AHI using FOSQ-10P. CONCLUSIONS: The Brazilian translation of FOSQ-10 is valid and reliable for identifying significant effects of excessive daytime sleepiness in patients with Obstructive Sleep Apnea.

RESUMO

The purpose of the study was to analyze the test-retest reliability of an isometric and isometric/vibratory muscular strength protocol in the bilateral seated bench press (BSBP), bilateral seated rowing (BSR), unilateral seated right knee extension (USKER), and left knee extension (USKEL) tests controlled using functional electromechanical dynamometry (FEMD) in healthy young adults. A repeated measures design was used to determine the reliability of a muscular strength protocol in isometric and isometric vibration modes with FEMD. No significant differences were found in test-retest analysis (p > 0.05; ES < 0.20); and high reliability (CV = 4.65-5.02%; ICC = 0.99-0.98) was found for BSBP measures, and acceptable reliability (CV = 3.71-9.61%; ICC = 0.98-0.95) was found for BSR, USKER, and USKEL. Furthermore, the coefficients between the two measures were strong (r = 0.963-0.839) and highly significant (p = 0.001) for maximal strength in the isometric and maximal isometric/vibratory assessment of muscle strength in all muscle strength tests. This study demonstrates that isometric and maximal isometric/vibratory strength in the BSBP, BSR, USKER, and USKEL tests can be measured with high reliability and reproducibility using the FEMD.

RESUMO

INTRODUCTION: Asthma symptoms are dyspnea, chronic cough, wheezing, chest tightness, or chest discomfort, which can directly limit the activities of daily living (ADL), which is frequently reported by adults with asthma. Evaluating ADL with a reliable protocol at the usual speed is necessary. OBJECTIVES: To investigate the validity, reliability, minimal detectable change (MDC), and standard error of measurement (SEM) of the Londrina ADL Protocol (LAP) for adults with asthma. METHODS: Adults with asthma were evaluated with the LAP test. Spearman's correlation coefficient was used to verify validity with the 6-min walk test (6MWT), Glittre-ADL test, and London Chest Activity of Daily Living (LCADL). To test the reliability, the test was reapplied in at least 30 min; the Wilcoxon test and Intraclass Correlation Coefficient (ICC), SEM, MDC, and learning effect were performed. RESULTS: Fifty-three individuals were included (26% men, 43 ± 15 years, BMI 28 ± 8 kg/m2, FEV1 70 ± 24%predicted). For convergent validity, the LAP test was correlated with the 6MWT, Glittre-ADL, and LCADL scale (r = -0.49, 0.71, and 0.30, respectively; p < 0.03). There was a difference in test-retest (p < 0.0001) and reliability analysis shows ICC3 of 0.94, SEM of 14.88 s (22%), and MDC of 41.23 s (15%). Furthermore, the individuals performed the second test with -23 ± 19 (7.9%) s. CONCLUSION: The LAP test is valid and reliable for assessing limitations during ADL in adults with asthma. Considerable learning effect was observed, therefore, the best of two measures may avoid underestimation.

RESUMO

OBJECTIVE: To analyze the reliability, measurement error, and responsiveness of the Voice Handicap Index (VHI) for measuring voice handicap in individuals with voice disorders. METHODS: This systematic review followed the recommendations of the COnsensus-based Standards for the Selection of Health Measurement INstruments. Studies that validated the VHI, analyzed the measurement properties of reliability, measurement error, or responsiveness, and had dysphonic individuals as the study population were included. The following electronic databases were searched: Cochrane Library, EMBASE, LILACS, PubMed, Scopus, and Web of Science. The manual search was carried out on gray literature in the Biblioteca Digital Brasileira de Teses e Dissertações and ProQuest Dissertation & Theses, in addition to mapping citations and consulting an expert in the field. Evidence selection, data extraction, risk of bias analysis, certainty of evidence, and good psychometric measurements were performed by two blinded and independent reviewers. A meta-analysis was performed using Fisher's transformed r-to-z correlation coefficient and standardized mean difference. Heterogeneity was calculated using Tau² and I² statistical tests in JAMOVI 2.3.2 software. RESULTS: Eighty studies were included in the meta-analysis. When assessing the risk of bias, most studies were classified as inadequate during the reliability and measurement error stages. In the responsiveness stage, they were classified as doubtful in the sensitivity and specificity sub-boxes and good in the comparison sub-box with a gold standard instrument. For psychometric properties, most studies were classified as indeterminate in terms of both reliability and responsiveness. In test-retest reliability and responsiveness, the average outcome differed significantly from zero, indicating agreement between the test and retest moments and a significant reduction in the VHI score after intervention. Considering certainty of the evidence, the level of evidence was very low in both the reliability and responsiveness stages. The analyzed studies did not evaluate observational errors, and hence, they were not considered in this review. CONCLUSION: The VHI proved to be reliable and responsive in measuring voice handicap. However, it should be used with caution, as there is heterogeneity, a risk of bias, and no adherence to the analysis of observational error.

RESUMO

The ORTO-15 is a commonly used screening instrument for symptoms of Orthorexia Nervosa (ON), an obsessive overconcern with healthy eating. However, its limitations have been evidenced in several published factorial models. We analyzed the psychometric properties of seven different ORTO-15 factorial models using data from Brazilian adult participants (n = 1455; 71.4% women; M age = 29.5, SD = 8.9 years) from the country's five macro-regions who answered online questions for sample characterization and completed the Portuguese version of the ORTO-15 containing 15 items. We tested the fit of each model separately, analyzing data for men and women with separate confirmatory factor analysis, and using the Weighted Least Squares Mean and Variance Adjusted estimation method and goodness-of-fit indices. We also calculated the average variance extracted and the alpha ordinal and omega coefficients to analyze the convergent validity and reliability of the factors. None of the models tested presented adequate properties of validity and reliability. Although we found some acceptable reliability coefficients, they do not guarantee the validity of the data. Future investigators should be cautious when choosing the ORTO-15 for ON screening.

RESUMO

BACKGROUND: Considering that beliefs may be assessed and changed, inventories measuring employability and career beliefs may be of utmost importance for career interventions. OBJECTIVE: This study introduces the psychometric properties of a brief version of the Employability and Career Beliefs Inventory (ECBI) in a sample of unemployed persons. METHODS AND RESULTS: Altogether, 2023 unemployed persons aged from 18 to 66 years old and living in Southern Portugal participated in an online survey. The ECBI's original internal structure was tested and did not fit the data. Exploratory and confirmatory factor analyses were implemented, and a three-factor solution was retained. The three factors discriminate three types of beliefs named growth, pessimism, and flexibility. Measurement invariance models identified scalar equivalence across gender and educational degree, and metric invariance across age. All items fit the graded response model's parameters. The growth and flexibility subscales were less effective in the assessment of low latent trait levels, whereas the opposite was observed with the pessimism subscale. Internal consistency is good yet discrimination between factors is questionable. Correlations to career decision-making self-efficacy evidence validity based on the relations to other constructs. CONCLUSION: Despite the limitations, the brief version of the ECBI proposed in this study is ready for further use and development among unemployed persons.

RESUMO

BACKGROUND: The Dysmenorrhea Symptom Interference (DSI) scale is a reliable, valid, and responsive tool to assess the interference of menstrual pain in the physical, mental, and social activities of women. OBJECTIVE: To translate and cross-culturally adapt the DSI scale into Brazilian-Portuguese (DSI-BrPt) and investigate the measurement properties of this version in on- and off-menses versions. METHODS: The original (United States) scale was translated and culturally adapted following existing guidelines. Measurement properties of the DSI-BrPt were investigated in 1387 women with dysmenorrhea. Reliability was analyzed via intraclass correlation coefficients (ICC) and test-retest reliability. Furthermore, structural validity, internal consistency (Cronbach's alpha), cross-cultural validity, construct validity (correlation with WHODAS 2.0 and SPS-6 scores questionnaires), and floor and ceiling effects were determined. RESULTS: No significant adaptations were needed during the translation process of the DSI-BrPt. The values of Cronbach's α were adequate (α ≥0.87) for the unidimensional scale. The test-retest reliability was considered adequate (ICC >0.78) and there was no systematic error for both on-menses and off-menses versions. Moreover, the DSI had a positive and strong correlation with WHODAS 2.0. There were no floor and ceiling effects neither for the total sample, nor among off-menses, or on-menses women. CONCLUSION: The DSI-BrPt scale has been translated and cross-culturally adapted successfully. The DSI-BrPt scale presented adequate measurement properties. The scale is valid and reliable, and, therefore, an adequate tool for monitoring dysmenorrhea symptoms in Brazilian women during and between menses.

RESUMO

The purpose of this study was to evaluate the fatigue survival of 5Y-PSZ zirconia infiltrated with an experimental glass and bonded onto dentin analogues. Disc-shaped specimens of a 5Y-PSZ (Katana UTML Kuraray Noritake) were cemented onto dentin analogs (NEMA G10) and divided into four groups (n = 15): Zctrl Group (control, without infiltration); Zglz Group (Glaze, compression surface); Zinf-comp Group (Experimental Glass, compression surface); Zinf-tens Group (Experimental Glass, tension surface). Surface treatments were varied. Cyclic fatigue loading, oblique transillumination, stereomicroscope examination, and scanning electron microscopy were performed. Fatigue data were analyzed (failure load and number of cycles) using survival analysis (Kaplan-Meier and Log-Rank Mantel-Cox). There was no statistically significant difference in fatigue survival between the Zglz, Zctrl, and Zinf-comp groups. The Zinf-tens group presented a significantly higher failure load when compared to the other groups and exhibited a different failure mode. The experimental glass effectively infiltrated the zirconia, enhancing structural reliability, altering the failure mode, and improving load-bearing capacity over more cycles, particularly in the group where the glass was infiltrated into the tensile surface of the zirconia. Glass infiltration into 5Y-PSZ zirconia significantly enhanced structural reliability and the ability to withstand loads over an increased number of cycles. This approach has the potential to increase the durability of zirconia restorations, reducing the need for replacements and save time and resources, promoting efficiency in clinical practice.

RESUMO

Introduction: Excessive internet and mobile cell phone use has been increasing in recent years especially in teenagers who are a vulnerable population. However, there is a lack of psychometric evaluation of instruments that allow to identify behavior regarding problematic use of the internet and cell phones in the Latin America, particularly in Ecuador. The main aim of this study is to examine the psychometric properties of two instruments: the Internet-related experiences questionnaire (IREQ) and Mobile-related experiences questionnaire (MREQ) in high school students (n = 4, 174, M age = 15.63; 51.19% male and 48.37% female). Methods: The validation process was performed using one and two factors for both questionnaires according to previous literature. After checking the models proposed to date, the best fit model was the one-factor model for (IREQ) and one-factor model for (MREQ). Results and discussion: The invariance was performed using two samples according to gender (male, female) and has been confirmed with an acceptable internal consistency for both questionnaires. For IREQ (All, ω = 0.80; Male, ω = 0.77; Female, ω = 0.82) and for MREQ (All, ω = 0.83; Male, ω = 0.82; Female, ω = 0.84). In addition, we performed the correlation analysis between IREQ, MREQ, and socio-demographic variables and finally, both instruments demonstrated strong psychometric qualities within the local population.
