Psychometric analysis of the GAD-7 questionnaire in Slovak helping professionals

The GAD-7 is a widely used screening tool for the measurement and diagnosis of symptoms of generalized anxiety disorder. It has been translated and validated across more than 20 cultural contexts. However, no study to date examined its psychometric properties in a Slovak sample, despite the fact that a Slovak translation exists. The purpose of the present study was to test psychometric properties and factor structure of GAD-7 in a general sample of Slovak helping professionals. It was hypothesized that a one-dimensional factor structure would be supported by the data, and that construct validity would be demonstrated. A total of 2239 participants (Mage = 42.20, SD = 14.30) from different helping professions (e.g., psychologists, teachers, special educators, medical doctors, nurses, speech-language pathologists) completed an online survey. A confirmatory factor analysis yielded satisfactory factor loadings and acceptable model fit of the tested one-dimensional model. This evidence was invariant by sex. Internal consistency coefficients indicated good reliability. Significant correlations were found between the GAD-7 and both negative and positive adjustment constructs, thus demonstrating convergent and discriminant validity, respectively. The results of this study add to the evidence on the GAD-7 and its applicability across cultures and support the use of a Slovak translation of the instrument.

Domestic Violence Experienced by Women: Construction and Validation of a Measurement Method

Domestic violence, also known as intimate partner violence, constitutes a major social scourge recorded in virtually every country in the world. Despite the fact that previous studies investigating this societal phenomenon have evaluated it from various perspectives, little is known about how it is experienced by victims. However, the lack of knowledge of this experience prevents us from understanding that despite the fact that they are involved in relationships marked by violence, many women do not leave them, thus putting their physical and psychological health at risk. To help fill this gap, this research constructs and validates a new scale specific to experienced domestic violence. After formulating and verifying its items, a validation study was conducted with a sample of 406 female participants, aged between 18 and 61 years (M=29.63; SD=8,688). Factor analyses report that this measure has a one-dimensional factor structure with 12 items. The reliability indices are satisfactory (α=.95). The same goes for convergent, discriminant and predictive validity. The scale of experienced domestic violence has a general scope which will allow researchers to carry out an in depth investigation into the psychological, social, economic and political causes and consequences of experienced domestic violence with a view, in particular, to considering interventions for the recovery of the victims.

What's in Your Dataset? Measuring Engagement in HIV Care Using Routinely Administered Items with a Population Disproportionately Burdened by HIV.

We evaluated the psychometric properties of a measure consisting of items that assess current HIV care continuum engagement based on established definitions in the United States. At baseline, participants in this longitudinal study, which included three time points from 2015 to 2020, were 331 young Black sexual minority men ages 18-29 living with HIV in the southern United States residing in two large southern cities. Self-report items reflected four aspects of HIV care continuum engagement as binary variables: seeing a healthcare provider for HIV care, being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. Of these, the following three variables loaded onto a single factor in exploratory factor analysis: being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. A one-dimensional factor structure was confirmed using confirmatory factor analyses at separate time points. Additionally, the three items collectively showed measurement invariance by age, education level, employment status, and income level. The three-item measure also showed reliability based on coefficient omega and convergent validity in its associations with indicators of socioeconomic distress, depression, resilience, and healthcare empowerment. In sum, the items performed well as a single scale. The study demonstrated the potential psychometric strength of simple, feasible, commonly administered items assessing engagement in the HIV care continuum.

Intercultural adaptation and influencing factors analysis of the Chinese version of the anxiety scale for the older adults in a long-term care population.

The purpose of this study was to translate the Geriatric Anxiety Scale-Long-Term Care into Chinese and to assess its reliability and validity in a long-term care population, as well as to explore factors contributing to anxiety in older adults requiring long-term care. The study recruited 399 older adults residents requiring long-term care and used the Brislin double translation-back-translation method to create the initial Chinese version of the Geriatric Anxiety Scale-Long-Term Care. The study used internal consistency and split-half reliability to assess the reliability of the scale, as well as exploratory factor analysis, validation factor analysis, and content validity to assess the validity of the scale. Linear regression was used to analyze the relationship between the independent variables and anxiety levels in the long-term care population. The Cronbach's coefficient value of the Chinese version of the Geriatric Anxiety Scale-Long-Term Care was 0.81, and the split-half reliability was 0.80. The results of exploratory factor analysis showed support for a one-dimensional factor structure. The results of the validation factor analysis indicated a good fit for the one-factor model. Gender (β = 0.190, 95% CI:0.540 ~ 1.546, p < 0.001), self-rated health (β = 0.220, 95% CI:0.379 ~ 0.953, p < 0.001), life satisfaction (β = -0.315, 95% CI: -1.355 ~ -0.734, p < 0.001) and participation in activities (β = -0.106, 95% CI: -1.122 ~ -0.084, p < 0.05) were significant predictors of anxiety levels in the long-term care population. The Chinese version of the Geriatric Anxiety Scale-Long-Term Care has good reliability and validity in the long-term care population. The Geriatric Anxiety Scale-Long-Term Care is effective in assessing the anxiety level of the Chinese long-term care older adults population and provides an opportunity to detect and observe anxiety disorders in the long-term care population.

Validation of the Body Appreciation Scale-2 in cisgender, heterosexual and sexual and gender minority adolescents and sexuality-related correlates

Body dissatisfaction has received considerable scientific attention, while research about positive body image has been neglected, particularly among adolescents. The aims of the present study were to examine (1) the factor structure of the Body Appreciation Scale-2 (BAS-2) in a large sample of cisgender, heterosexual and sexual and gender minority adolescents, (2) measurement invariance across language, gender and sexual orientation-based groups, (3) convergent validity with sexuality-related outcomes and (4) one-year temporal stability. Results of a confirmatory analysis among 2419 adolescents (Mage=14.6 years, SD=0.62; 52.6% girls) corroborated the proposed one-dimensional factor structure of the scale. The BAS-2 demonstrated adequate reliability and one-year temporal stability. The scale was partially invariant across gender and fully invariant across language and cisgender heterosexual and sexual and gender minority adolescents. Boys (cis and trans) had higher levels of body appreciation than girls (cis and trans), while no significant differences were observed between heterosexual and sexual minority adolescents. The BAS-2 correlated positively with sexual satisfaction and sexual body-esteem as well as negatively with sexual distress. Our findings support the validity and reliability of the BAS-2 in French and English for measuring body appreciation in adolescents.

Portuguese version of the Body Appreciation Scale-2 for Children (BAS-2C): Psychometric evaluation and measurement of invariance across sex

Body appreciation, a central aspect of positive body image, recently started to capture the attention of the scientific community as a potential determinant of well-being. However, little is known about onset and early identification in both males and females, as studies on this subject in childhood are still scarce, due in part to a dearth of validated instruments. Therefore, the main purpose of this study is to examine the psychometric properties and sex invariance of a Portuguese version of the Body Appreciation Scale-2 for Children (BAS-2C; Halliwell et al., 2017). We also explored the relationship between the BAS-2C and body mass index z-scores (BMIz). Participants were 328 children, ages 9-to-11 years (50.9% girls). Confirmatory factor analysis indicated that the one-dimensional factor structure had adequate fit, but sex invariance was not supported. Differential item functioning analysis revealed that boys and girls respond differently to item #9, which assesses body comfort. BAS-2C scores evidenced internal consistency and convergent validity with quality of life, healthy eating habits, and body size dissatisfaction. BMIz showed a low ability to predict body appreciation. This study brings support for the use of the BAS-2C in Portuguese-speaking children, but caution is warranted in comparing BAS-2C scores across sexes.

Psychometric properties of the Short Warwick-Edinburgh Mental Well-Being Scale in a sample of Danish schoolchildren.

The aims of this this study was to examine the psychometric properties, including internal consistency and construct validity, of the Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS) in a sample of Danish schoolchildren aged 10-16 years. A total of 1155 schoolchildren (54% girls) aged 10-16 years (Mage=12 years, SD=1.3) responded to an electronic questionnaire as part of the Danish SELFCARE study. To examine the internal consistency and construct validity of the SWEMWBS, we performed descriptive statistics, reliability and correlation analyses in Stata as well as confirmatory factor analysis (CFA) in Mplus. Correlations between scores on the SWEMWBS and scores on scales from the Strengths and Difficulties Questionnaire (SDQ) were calculated using Spearman's rank correlation coefficients. The analysis was conducted on the general study population and in subgroups divided by sex and class (age groups). CFA confirmed SWEMWBS one-dimensional factor structure, and the model fit the data well (CFI=0.984, TLI=0.97, RMSEA=0.062 and SRMR=0.021). The scale showed satisfactory internal consistency (ɑ=0.78) and composite reliability (ω=0.82). In addition, the scale was shown to have acceptable construct validity. Thus, correlations between scores on the SWEMWBS and SDQ subscales were in line with expectations. Corresponding results were found for subgroups divided by sex and class (age groups). Our study indicates that the Danish translation of the SWEMWBS is valid for measuring well-being among Danish schoolchildren aged 10-16 years. This construct validation study is among the first to validate the SWEMWBS in younger populations.

Development and Psychometric Testing of a Taiwanese Team Interactions and Team Creativity Instrument (TITC-T) for Nursing Students.

Background: How well team members work together can be affected by team interactions and creativity. There is no single instrument for measuring both variables in healthcare education settings in Taiwan. The purpose of this study is to develop an instrument to measure team interactions and team creativity for Taiwanese nursing students. Methods: A 34-item team interactions and team creativity self-report instrument was developed for nursing students in Taiwan (TITC-T). Items consisted of statements about how a participant perceived their team members’ constructive controversy, helping behaviors, communication, and creativity. Nursing students (n = 275) were recruited from two campuses of a science and technology university to examine the psychometric properties of the TITC-T. The reliability and psychometric properties were evaluated. Results: The Cronbach’s alpha was 0.98. The confirmatory factor analysis resulted in a one-dimensional factor structure that fit well with the model (Comparative Fit Index = 0.995, Tucker Lewis Index = 0.908, Root Mean Square Error of Approximation = 0.098). Conclusions: The TITC-T is a valid and reliable tool for evaluating team interactions and team creativity for students enrolled in nursing programs in Taiwan.

Validation of the Spanish version of the Physical Appearance Comparison Scale-Revised (PACS-R): Psychometric properties in a mixed-gender community sample

The objectives of this study were to examine the validity and reliability of the Spanish version of the Physical Appearance Comparison Scale-Revised (PACS-R) and to assess its ability to predict body dissatisfaction and disordered eating in a community sample in Spain. A total of 1405 participants (83.6% women; aged 14-64) completed the Spanish PACS-R along with measures of body image, eating disturbances, appearance-related sociocultural influences, self-esteem and social comparison. Exploratory and confirmatory factor analyses supported the original one-dimensional factor structure for the 11-item Spanish version of the PACS-R. Women had significantly higher PACS-R scores than men. Internal consistency of the measure was excellent, and results showed good test-retest reliability and convergent validity in men and women. Regression analyses demonstrated the utility of the scale in predicting body dissatisfaction and disordered eating in both genders. Results suggest that the Spanish PACS-R has excellent psychometric properties, therefore it might be a useful tool to measure appearance comparisons among Spanish speaking populations.

Preliminary Study of the Psychometric Properties of a Questionnaire to Assess Spanish Canoeists' Perceptions of the Sport System's Capacity for Talent Development in Women's Canoeing.

Given the importance of sport at a global level, the competitiveness of sport systems is a determining factor in attracting resources from different sectors. Competitiveness is largely measured by the athletes’ level. Therefore, the production of competitive talent is an aspect that occupies the managers of different sports systems. This study analyzed the factor structure and reliability of a questionnaire for the evaluation of the perceptions of actors of a sport (canoeing) on the ability of the national system to produce talent in one of its modalities recently incorporated in the Olympic Games (OG) of Tokyo 2021. The sample consisted of 167 individuals linked to Spanish canoeing, who responded to the questionnaire “Evaluation of the current position in canoeing-sport with regard to talent” of the International Canoe Federation (ICF). Exploratory, confirmatory and reliability factor analyses were performed. The results showed a one-dimensional factor structure composed of seven items, with good and excellent goodness-of-fit values and high reliability (McDonald’s Omega = 0.82). Thus, the ICF questionnaire can be considered a quick and easy to apply tool to analyze the perceptions about the development of talent in canoeing in order to take actions for the recruitment, promotion and development of talent.

Validation of a German version of the Body Appreciation Scale-2 (BAS-2)

The Body Appreciation Scale-2 (BAS-2) is the most current measure of body appreciation, a central facet of positive body image. This work aimed to examine the factor structure and psychometric properties of a German version. In Study 1 (N = 659; Mage = 27.19, SD = 8.57), exploratory factor analyses (EFA) revealed that the German BAS-2 has a one-dimensional factor structure in women and men, showing cross-gender factor similarity. In Study 2 (N = 472; Mage = 30.08, SD = 12.35), confirmatory factor analysis (CFA) further supported the original scale’s one-dimensional factor structure after freeing correlated errors. The German BAS-2 also showed partial scalar invariance across gender, with women and men not differing significantly in latent mean scores. As predicted, we found convergent relationships with measures of self-esteem, intuitive eating, and variables associated with negative body image (i.e., weight- and shape concerns, drive for thinness). Correlations with BMI were small and in an inverse direction. Incremental validity was demonstrated by predicting self-esteem and intuitive eating over and above measures of negative body image. Additionally, the German BAS-2 showed internal consistency and 2-week test-retest reliability. Overall, our results suggest that the German BAS-2 is a psychometrically sound instrument.

Self-Criticism in the General Population: Development and Psychometric Properties of the Depressive Experiences Questionnaire Self-Criticism 4 (DEQ-SC4)

Self-criticism is a stable personality trait identified as a serious risk factor for psychopathology and weight-related health problems. Therefore, it is relevant to epidemiological research, which requires a relatively brief instrument for measuring trait self-criticism in the general population. The current study introduces a brief measure of self-criticism and presents empirical results that inform on its reliability and validity. Based on the six-item version of the Depressive Experiences Questionnaire Self-Criticism (DEQ-SC6), thorough psychometric analyses on a German representative sample (N = 2,516) were conducted and resulted in the final four-item scale: the Depressive Experiences Questionnaire Self-Criticism 4 (DEQ-SC4). Its internal consistency was good and a one-dimensional factor structure showed a good model fit. In terms of construct validity, the DEQ-SC4 was moderately linked to symptoms of depression and a non-linear association between the DEQ-SC4 and body mass index was observed, with the highest levels of self-criticism reported by underweight participants. In addition, the DEQ-SC4 showed high positive correlations with another short version of the DEQ-SC and the Big Five personality dimensions assessed in samples of university students (N = 206) and patients (N = 55), meeting theoretically-based expectations. The DEQ-SC4 therefore represents a brief screening measure of self-criticism in the general population with good psychometric properties.

Validation of the German Benefit Finding Scale for Youth with chronic conditions

BackgroundBenefit finding, defined as perceiving positive life changes resulting from adversity and negative life stressors, gains growing attention in the context of chronic illness. The study aimed at examining the psychometric properties of the Benefit Finding Scale for Children (BFSC) in a sample of German youth facing chronic conditions.MethodsA sample of adolescents with various chronic conditions (N = 304; 12 – 21years) completed the 10-item BFSC along with measures of intra- and interpersonal resources, coping strategies, and health-related quality of life (hrQoL). The total sample was randomly divided into two subsamples for conducting exploratory and confirmatory factor analyses (EFA/CFA).ResultsEFA revealed that the BFSC scores had a one-dimensional factor structure. CFA verified the one-dimensional factor structure with an acceptable fit. The BFSC exhibited acceptable internal consistency (α = 0.87 – 0.88) and construct validity. In line with our hypotheses, benefit finding was positively correlated with optimism, self-esteem, self-efficacy, sense of coherence, and support seeking. There were no correlations with avoidance, wishful thinking, emotional reaction, and hrQoL. Sex differences in benefit finding were not consistent across subsamples. Benefit finding was also positively associated with age, disease severity, and social status.ConclusionsThe BFSC is a psychometrically sound instrument to assess benefit finding in adolescents with chronic illness and may facilitate further research on positive adaptation processes in adolescents, irrespective of their specific diagnosis.

Psychometric properties of the Suicidal Ideation Attributes Scale (SIDAS) in a longitudinal sample of people experiencing non-affective psychosis

BackgroundSuicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity.MethodsNinety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale.ResultsPrincipal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity.ConclusionThe SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.

Development and Psychometric Evaluation of the Experiences of Social Inclusion Scale

ABSTRACT In recent years, a growing body of literature on social inclusion on an individual level has emerged. Yet, there is no common understanding of the concept itself and how to measure it. The objective of this study was to document the development of the Experiences of Social Inclusion Scale (ESIS), including the theoretical framework used for this purpose, which draws strongly on the capability approach. The ESIS is a brief closed survey instrument to assess self-reported experiences of social inclusion, and the aim was to evaluate its psychometric properties. The sample used for this consisted of 847 adults aged 18–87 years from all over Finland, most of them affected by or at immediate risk of social exclusion. The results indicated good internal reliability and consistency (Cronbach’s alpha = 0.89). Furthermore, factor analyses suggested a one-dimensional factor structure for the ten items of the ESIS. The mean score on the ESIS was not statistically significantly different between male and female respondents, whereas a weak positive association with age and statistically significant differences for experiences of poverty were found. Analyses for convergent validity showed that the ESIS was statistically significantly associated with instruments measuring related concepts. All correlations were in the expected direction and rather substantial in magnitude but did not indicate that the same construct was being measured (r = .409 to r = .678). These promising results indicate a broad applicability of the ESIS in self-administered questionnaires, and its use in future research is encouraged.

Adaptation of the Devaluation-Discrimination Scale Into Turkish: A Comprehensive Psychometric Analysis.

The Devaluation-Discrimination Scale (DDS) is among the most frequently used stigma scales for measuring the perception of social stigma related to mental illness. The DDS is also frequently employed to test predictions of modified labeling theory and is modified to use for specific disorders, such as depression, substance abuse, and alcohol use disorders. Although modified versions of the DDS have been subjected to psychometric analyses, the original has never undergone a full psychometric evaluation. Thus, the aim of this study was to comprehensively examine the psychometric properties of the Turkish adaptation of the original DDS, with all positively keyed items, across seven studies in Turkish student and community samples (N = 1,907). The results of the exploratory factor analysis indicated that a one-dimensional factor structure adequately explained the covariation among DDS items in a sample of college students. Moreover, the single-factor structure of the DDS was corroborated, and invariant across sex, age, educational level, mental health diagnosis status, and previous help-seeking experience among Turkish adults. The convergent and divergent validity of DDS scores also were supported by significant correlations in the hypothesized directions with self-stigma (r = .26), social stigma (r = .46), attitudes toward seeking professional psychological help (r = -.24), and intention to seek psychological help scores (r = -.24). The results of the reliability analyses suggested that the DDS has good temporal stability in a 1-month time interval (r = .83, intraclass correlation coefficient = .83) and possesses high to excellent internal consistency reliabilities ranging from .88 to .92 across five studies. The examination of the distribution of total DDS scores indicated that there were no floor and ceiling effects in DDS scores across five different samples. The Turkish adaptation of the original DDS may be used as a valid and reliable scale to measure the devaluation and discrimination perceptions of college students and adults against people with mental illness.

Translation and validation of an Italian version of the Body Appreciation Scale-2

Body appreciation is considered a key dimension of positive body image. Tylka and Wood-Barcalow (2015) developed the Body Appreciation Scale-2 (BAS-2), a psychometrically sound measure to assess body appreciation. The present study examines various psychometric properties (i.e. factor structure, sex-based measurement invariance, and construct validity) of an Italian translation of the BAS-2 in a community sample (N = 601; F = 50.6 %; Mage = 25.72; SD = 4.81). Exploratory factor analyses with a randomly selected split-half subsample (n = 300; F = 50 %) supported the one-dimensional factor structure among both sexes. Confirmatory factor analyses with a second split-half subsample (n = 301; F = 51.16 %) indicated that the one-dimensional factor structure had adequate fit after some modifications were made. BAS-2 scores achieved full invariance across sex and men reported significantly higher scores than women (d = 0.45). Further, the Italian version of the BAS-2 had good internal consistency and was positively correlated with self-esteem and life satisfaction, whereas negative associations were found with body dissatisfaction and eating disorder symptoms. Results indicated that the Italian BAS-2 has good psychometric properties.

Traducción al español y validación de una medida breve de ansiedad por la COVID-19 en estudiantes de ciencias de la salud

Introduction and objectivesCOVID-19 has generated negative consequences for people's mental health. This is the case of Peru, one of the Latin American countries most affected by the pandemic. In this sense, the objective of the study was to translate and validate the Coronavirus Anxiety Scale (CAS) into Spanish. Material and methodThe participants were 704 university students of health sciences (Mage = 23.39 years, SD = 3.45) who were administered the CAS in Spanish, the Mental Health Inventory-5 and the Patient Health Questionnaire-2 item. The CAS was translated into Spanish using the forward and backward method. Reliability and evidence of validity based on internal structure and relationship with other variables were examined. ResultsThe factor analysis confirmed the one-dimensional factor structure of the CAS (χ2 = 7.62, df = 5, p = .18, χ2 / gl = 1.52, CFI = .99, RMSEA = .03 [90% CI .00, .06]; SRMR = .02, WRMR = .52); In addition, the factor loadings were large and significant (from .68 to .87). The five CAS items showed acceptable corrected total test item correlations (from .64 to .74). Reliability due to internal consistency was good (ω = .89; αordinal = .89). The validity evidence based on the relationship with other CAS variables was supported by the positive correlation with depression (r = .52, p < .01) and negative with subjective well-being (r = -.50, p < . 01). Furthermore, depression mediates the relationship between COVID-19 anxiety and subjective well-being (bootstrap value = - .24, 95% CI = - .28, - .20). ConclusionThe Spanish version of the CAS has evidence of validity and reliability to measure anxiety by COVID-19 in a sample of Peruvian university students.

The body appreciation scale-2: Translation and validation in the greek language

The psychometric properties of a Greek translation of the 10-item Body Appreciation Scale-2 (BAS-2) was examined. A total of 193 Greek-speaking female university students from Cyprus completed the BAS-2, along with measures of appearance satisfaction, investment in appearance, weight-related anxiety, self-esteem and body image quality of life. Principal-axis factor analysis indicated that the Greek version of the BAS-2 scores had a one-dimensional factor structure. A Confirmatory Factor Analysis confirmed the unidimesionality of the measure. Further analyses indicated that Greek BAS-2 scores evidenced internal consistency, test-retest reliability and convergent validity with the other variables of interest. These results suggest that the Greek version of the BAS-2 has adequate psychometric properties and can be used within the Greek-speaking populations.

Translation and validation of a Brazilian Portuguese version of the Body Appreciation Scale-2 in Brazilian adults

We examined the psychometric properties of a Brazilian Portuguese translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). A sample of 990 Brazilian adults (560 women, 430 men; Mage = 31.10, SD = 8.94) completed the BAS-2 and measures of life satisfaction, self-esteem, actual-ideal weight discrepancy (women only), breast size dissatisfaction (women only), drive for muscularity (men only), and disordered eating behaviours. Exploratory factor analyses indicated that BAS-2 scores reduced to a single dimension with all 10 items in women and men. Confirmatory factor analysis supported the fit of this one-dimensional factor structure following freeing of error covariances between two pairs of items. BAS-2 scores achieved full scalar invariance across sex, and men had significantly higher BAS-2 scores than women. Internal consistency coefficients were adequate and test-retest reliability was supported up to three weeks in a subsample of 221 participants (140 women, 81 men). Evidence of construct validity was demonstrated through positive associations with indices of psychological well-being and negative associations with indices of negative body image and disordered eating behaviours. Availability of a Brazilian Portuguese translation of the BAS-2 should help to promote greater understanding of positive body image in the Brazilian context.
