- The Arabic Control Attitudes Scale-Revised: Method Effect (Negatively Worded Items) and Measurement Invariance as Threats to Its Construct Validity Are Remedied in a 5-Item Version With Improved PerformancePublication . Ali, Amira Mohammed; Al-Dossary, Saeed A.; Alharrasi, Maryam; Laranjeira, Carlos; Ayed, Ahmad; El-Gazar, Heba Emad; Zoromba, Mohamed Ali; Atalla, Amal Diab Ghanem; Alamer, Rasmieh; Al-Abri, Khalood; Subih, Maha; Pakai, AnnamariaBackground: The Control Attitudes Scale-Revised (CAS-R) is widely used to explore cardiac patients’ beliefs about their ability to manage illness. The CAS-R’s construct validity may be questionable in different cultural contexts. Conclusions/applications based on inaccurate construct validity can be misleading and incorrect. Objective: In this study, we aimed to evaluate the psychometric properties of the Arabic version of the CAS-R. Methods: Within a cross-sectional design involving 180 Omani patients with heart failure (mean age = 70.3 ± 9.8 years, 51.7% females), exploratory/confirmatory factor analysis (CFA) and multigroup CFA were used to evaluate the construct validity and measurement invariance of the CAS-R across gender and marital groups. Results: In exploratory factor analysis, 2 factors with eigenvalues >1 explained 37.9% of the variance. Despite the poor fit of the unidimensional CAS-R, CFA revealed an excellent fit of a 2-factor structure. Negative (5 and 8) and cross-loading items (1) contributed to scale variance at the configural level. Eliminating negative items and item 6 improved model fit, reliability (Cronbach’s α = 0.66 vs. 0.56), and invariance at all levels. In support of its convergent and criterion validity, the CAS-R 5 correlated with the CAS-R and depression (r = 0.953, −0.268; P values <.01). Conclusions: Negative items comprised a minor weak factor (helplessness) that was not stable across groups. Eliminating items 5, 6, and 8 resulted in a clean invariant short form (CAS-R 5) with superior properties that may implicate nursing decisions and interventions concerning perceived control.
- The Arabic Generalized Anxiety Disorder 2 (GAD-2): Psychometric evaluation among mothers of children with intellectual disabilitiesPublication . Ali, Amira Mohammed; Al-Dossary, Saeed A.; Fekih-Romdhane, Feten; Laranjeira, Carlos; Khatatbeh, Haitham; El-Gazar, Heba Emad; Ayed, Ahmad; Alkhamees, Abdulmajeed A.; Aljaberi, Musheer A.; Alamer, Rasmieh; Pakai, Annamaria; Zoromba, Mohamed AliIntroduction Disruptive behaviours of children with intellectual disabilities predispose mothers to mental and physical morbidities, leading to caregiving burnout, lower childcare quality, and poor child progress. Methods This cross-sectional study investigated the psychometrics of the Arabic version of the Generalised Anxiety Disorder 2-item scale (GAD-2) among 85 Saudi mothers of children with intellectual disabilities through latent variable model and receiver-operating characteristic curve analyses. Results The unidimensional GAD-2 demonstrated good construct validity, invariance at the configural, metric, and scalar levels across age groups, and adequate convergent/divergent validity—It was negatively predicted by high mood and happiness and positively predicted by stress, and it mediated the effect of stress and happiness on depression. Its known-group validity was determined by elevated anxiety levels among mothers using psychotropic drugs. Two cut-offs (≥2.5 and ≥3.5) flagged the best trade-off between sensitivity and specificity for predicting low mood, poor sleep quality, nightmares, high stress, low general physical health, and willingness to join a psychological support program. The positive predictive value for the cut-off ≥3.5 was higher for all outcomes than that of the cut-off ≥2.5. Discussion The GAD-2 is a valid and reliable tool, which at thresholds ≥3.5 can identify anxious mothers, aiding early diagnosis and intervention.
