The 12-Item General Health Questionnaire (GHQ-12) has shown the best fit in both a one-factor structure and a multidimensional structure for the screening of common mental disorders and psychiatric well-being. The aim was to test for reliability and validity and ascertain the factor structure of the GHQ-12 in a South African HCW population. Data were collected from 832 public hospital and clinic staff during the coronavirus disease 2019 (COVID-19) pandemic in Gauteng, South Africa. The factor structure of the GHQ-12 in this professional population was examined by exploratory factor analysis (EFA) to identify factors, confirmatory factor analysis (CFA) for construct validity and structural equation modelling (SEM) to establish model fit. The GHQ-12 median score was higher (<i>n</i> = 25) in women than in men (<i>n</i> = 24), <i>p</i> = 0.044. The assumptions for inferential statistics were tested: the determinant for the correlation matrix was 0.034, Bartlett's test of sphericity was <i>p</i> < 0.001, Chi-square 2262.171 and the Kaiser-Meyer-Olkin (KMO) of sampling adequacy was 0.877. The four factors identified were labelled as social dysfunction (37.8%), anxiety depression (35.4%), capable (24.9%) and self-efficacy (22.7%).

As a result, systematic comparison frameworks have been developed to guide such decisions. The Consensus-based Standard for the Selection of Health Measurement Instruments (COSMIN) is one example of such a framework to examine the quality of psychometric studies. This article aimed, firstly, to explore the psychometric characteristics of resilience measures used in the South African Navy (SAN), in that context. Secondly, it aimed to illustrate the application of the COSMIN guide for comparing psychometric scales and employing data from the aforementioned resilience measures, as a practical case study. The study drew on both published and unpublished data from seven SAN samples, using eight psychometric scales associated with resilience. It assessed structural validity, construct validity, internal reliability and predictive ability. The outcomes were tabulated, and the COSMIN criteria were applied to each data point. All eight scales provided some degree of evidence of validity. However, it was at times difficult to differentiate between the scales when using the COSMIN guidelines. In such cases, more nuanced criteria were necessary to demonstrate more clearly the differences between the psychometric characteristics of the scales and ease in subsequent decision-making.Contribution: This article illustrated the application of COSMIN guidelines to systematically compare the quality of psychometric study outcomes on local South African data. It further offered evidence of validity for a range of resilience-related measures in a South African context.","PeriodicalId":34043,"journal":{"name":"African Journal of Psychological Assessment","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141828426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a cross-sectional research design, the phonemic verbal fluency of a sample (n = 156) of healthy adults (ages 18–60 years) with different linguistic and educational backgrounds from a non-WEIRD (western, educated, industrialised, rich and democratic) context was assessed using the COWAT-FAS (including the F, A, S, total correct, repetition, incorrect, and total errors). Pearson’s correlations showed significant negative associations between age and most of the COWAT scores, including the total (r = –0.47; p 0.01) and significant positive associations between years of education and all of the COWAT scores, including the total (r = 0.49; p 0.01). The number of languages spoken was not significantly correlated with any of the COWAT scores, but multilinguals who identified English as a first language performed significantly better than those who identified English as a secondary language for several COWAT scores, including the total (t154 = 3.85; p 0.001; d = 0.79). Age (B = –0.32; p 0.001), years of education (B = 0.35; p 0.001), and language position (B = –0.20; p 0.01) also significantly predicted the COWAT total score (r2 = 0.38; F = 18.34; p 0.001; f2 = 0.61). The implications of these findings for use of the COWAT-FAS in multilingual and non-WEIRD contexts are discussed.Contribution: This article supports the importance of understanding the role demographic variables play in cognitive performance and how they represent a source of bias in cognitive testing, particularly in the COWAT-FAS. It highlights how age, level of education, and the correspondence, or lack thereof, between first language and language of assessment, impacts phonemic fluency tasks. This knowledge may help to manage biases when conducting verbal fluency assessments with multilingual individuals and in non-WEIRD contexts.","PeriodicalId":34043,"journal":{"name":"African Journal of Psychological Assessment","volume":"10 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141099778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the measurement invariance of the nine-item versions of the Job Security Index (a measure of cognitive job insecurity) and the Job Security Satisfaction Scale (a measure of affective job insecurity), across four countries (i.e. the United States, N = 486; China, N = 629; Italy, N = 482 and South Africa, N = 345). Based on a novel bifactor-(S-1) model approach we found evidence for partial metric, partial scalar and partial strict invariance of our substantive bifactor-(S-1) structure. The results extend measurement invariance research on job insecurity with obvious pragmatic implications (e.g. scaling units, measurement bias over cross-national interpretations).Contribution: This research provides evidence to support the applied use of cross-national comparisons of job insecurity scores across the nationalities included in this study. Theoretically, this research advances the debate about the nature of the relationship between cognitive and affective job insecurity, suggesting that in this cross-national dataset, a model where cognitive job insecurity is specified as the reference domain outperforms a model where affective job insecurity is assigned this status. Practically, it demonstrates that it is sensible and necessary to differentiate between cognitive and affective job insecurity and include measures of both constructs in future research on the construct.","PeriodicalId":34043,"journal":{"name":"African Journal of Psychological Assessment","volume":"15 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140658618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since the student population is very diverse in South Africa, questionnaires measuring the well-being of students must be psychometrically sound for different cultural and demographic groups. This study aimed to determine the psychometric properties of the Mental Health Continuum Short-Form (MHC-SF), including factorial validity, measurement invariance, item bias and internal consistency. The sample consisted of 1285 first-year university students. The three-factor structure of the MHC-SF was confirmed, indicating that emotional, social and psychological well-being are three independent factors. Invariance results showed that the MHC-SF produced similar results across campuses and gender sub-groups, although partial invariance was present among language groups. Item bias was present for different sub-groups, but the practical impact was negligible. Reliability scores indicated that all three dimensions are reliable in this sample. This study’s findings could help higher education institutions with preliminary results on the validity and reliability of a widely used well-being measure to assess university students’ subjective well-being and could aid in investigating and measuring first-year students’ overall well-being during their transition to tertiary education.Contribution: This study contributes to creating knowledge about fair and unbiased measurement of student well-being across different sub-groups in South Africa.","PeriodicalId":34043,"journal":{"name":"African Journal of Psychological Assessment","volume":"35 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140378392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
