The Short Health Anxiety Inventory is a brief instrument to assess health anxiety widely used across countries; however, no validated version is available for Portuguese-speaking population. Factorial structure, reliability, and equivalency factor with the Spanish version were analyzed with Portuguese adolescents aged 14–18 years. A Portuguese adolescent cohort ( N = 629) and a comparative Spanish adolescent cohort ( N = 1502) were evaluated. The original two-factor version was the best fitting model for the Portuguese version. The reliability was excellent. Complete measurement invariance across both countries was supported. The Portuguese version of the Short Health Anxiety Inventory is a valid screening inventory to assess health anxiety in adolescents.

Especially since the last decades of the 20th century, research about resilience provided some insights into how people deal and overcome adversity in a positive way. Given the recent research history on this topic, discussion about theories and measures is still ongoing. In this study we aim to explore the structural invariance of the Wagnild and Young’s Resilience Scale (RS), one of the most widely used measures of resilience, across Portuguese and Brazilian adolescents. A sample of 969 adolescents with ages ranging between 13 and 18 years old completed the RS. A five- and a two-factor structure for the full RS version with 25 items and a one-factor structure for a RS short version, composed of 14 items, were tested using confirmatory factor analysis (CFA). After determining the best fitting structure, a multi-group CFA was performed to test the invariance of the instrument across the Portuguese and Brazilian samples.  The five- and two-factor structures for the full version revealed a poor fit. The one-factor structure revealed a good fit in both samples. Moreover, evidence for the partial measurement invariance of the short version across both samples was found. Our results indicate that the RS short version can be used for cross-cultural studies of resilience in both countries and that the five- and two-factor structures might be inadequate for comparison purposes.

The COVID Stress Scales (CSS) were developed to measure stress in response to the COVID-19 pandemic. To further investigate the psychometric properties of the CSS, we used data collected in Poland across two waves of assessment (N = 556 at T1 and N = 264 at T2) to evaluate the factor structure, reliability (at the item and scale level), measurement invariance (across the Polish and Dutch translations of the CSS, and time), over time stability, and external associations of the Polish-language version of the CSS (CSS-PL). Overall, results suggest that the CSS-PL is psychometrically robust, largely invariant across the countries and time-lags considered. The CSS-PL was also positively related to other measures of COVID-19 fear, health anxiety, obsessive compulsive symptoms, anxiety, depression, and intent to receive a COVID-19 vaccine. This study thus provides considerable information about the CSS’s items and scales, and lays the foundation for future investigations into COVID stress across time and different populations.

ObjectivesDespite being commonly used in research and clinical practice, the evidence regarding the factor structure of the Beck Depression Inventory-II (BDI-II) remains equivocal and this has implications on how the scale scores should be aggregated. Researchers continue to debate whether the BDI-II is best viewed as a unidimensional scale, or whether specific subscales have utility. The present study sought to test a comprehensive range of competing factor analytic models of the BDI-II, including traditional non-hierarchical multidimensional models and confirmatory bifactor models.MethodParticipants (n=370) were clinical outpatients diagnosed with either depressive episode or adjustment disorder. Confirmatory factor analysis and confirmatory bifactor modelling were used to test 15 competing models. The unidimensionality of the best fitting model was assessed using three strength indices (explained common variance, percentage of uncontaminated correlations and ω hierarchical).ResultsOverall, bifactor solutions provided superior fit than both unidimensional and non-hierarchical multidimensional models. The best fitting model consisted of a general depression factor and three specific factors: cognitive, somatic and affective. High factor loadings and strength indices for the general depression factor supported the view that the BDI-II measures a single latent construct.ConclusionsThe BDI-II should primarily be viewed as a unidimensional scale, and should be scored as such. Although it is not recommended that scores on individual subscales are used in isolation, they may prove useful in clinical assessment and/or treatment planning if used in conjunction with total scores.

Abstract Although memory complaints are assessed with a variety of items to track change in individuals as they age, it remains unclear which items best capture change. Adults aged 70 to 104 (n=1,344, 38% Male) completed six memory complaints items annually for up to 11 years: frequency of problems, one year decline, ten year decline, seriousness of problems, forgetting important things, and current functioning compared to functioning at age 30. Using multilevel exploratory factor analysis, the best fitting model indicated one factor fit the between person structure with all items loading significantly. Across time, items required two factors. Items about decline loaded together while the item about functioning compared to functioning at age 30 dominated a second factor. Remaining items did not load on either factor across time. This suggests these items assessing memory complaints are better at discriminating across persons rather than tracking changes within a person across time.

Measurement instruments that have satisfactory psychometric properties are needed to improve mental health research and services, especially in the effort to measure, identify, and monitor the psychological problems experienced by individuals. The purpose of this study is to examine the psychometric properties of the Indonesian version of the Depression Anxiety Stress Scale (DASS). The study involved 1,922 participants from Surabaya aged between 16 and 26. The data were obtained using the convenience sampling method. Testing of the factor structure, reliability, and measurement invariance of the Indonesian DASS was performed using a confirmatory factor, composite reliability, and multi-group analysis. It was found that a bifactor model consisting of specific (depression, anxiety, and stress) and general (psychological distress) factors was the best structure for the DASS. Furthermore, the model also showed satisfactory composite reliability and measurement invariance across genders. The results indicated that the Indonesian version of the DASS was a valid and reliable instrument for measuring and comparing depression, anxiety, stress, and psychological distress between genders in the Indonesian sample.

Life Scale

The Satisfaction with Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, 1985) is one of the most widely used scales for the measurement of well-being. Nevertheless, its measurement invariance and factor structure have not been investigated simultaneously across culturally diverse samples in Latin America. The current paper evaluates the factorial structure and measurement invariance of SWLS (the degree to which the scale measurements conducted across different populations exhibit identical psychometric properties) as to provide solid and accurate basis for cultural group comparisons. We apply measurement invariance testing procedures using multigroup confirmatory factor analysis (MGCFA) to investigate the factorial structure and invariance of the scale across three cultural groups from Argentina, Mexico and Nicaragua. We also estimate and compare latent means of life satisfaction across groups. Participants were 921 adults (mean age 29.66, SD = 11.48) from Argentina (n = 192), Mexico (n = 421) and Nicaragua (n = 302). First, confirmatory factor analyzes (CFA) conducted separately for each cultural group provided support for the one-factor structure of the instrument. Second, the MGCFA showed good configural, metric and scalar invariance models, indicating similar patterns and strengths in factor loadings, means and intercepts across cultural samples. Third, latent mean comparisons did not show group differences in life satisfaction. We conclude that the SWLS is a brief and valid measure of life satisfaction that can be used for cross-cultural comparison with samples from Argentina, Mexico and Nicaragua.
