“…We used the classical test theory and item response theory (Mokken analysis) in two different groups of samples, one including teachers and the other including students. Assessing measurement equivalence across different population groups is important [39,40]. Similar coherence or structure of the psychometric properties of data from multiple groups provides strong evidence of metric equivalence.…”

An important mental health concern arising from the COVID-19 pandemic was the loneliness resulting from the lockdown measures taken by many countries due to the outbreak. Thus, loneliness needs to be studied in detail for intervention purposes. The UCLA Loneliness Scale is the most widely used measure of loneliness. However, the 20-item measure has some drawbacks, including questionnaire fatigue, especially when used with other measures, and a lack of accurate responses to all items. In this study, we evaluated two short forms of the UCLA Loneliness Scale used in other studies (UCLA-10 and UCLA-8), as well as a five-item version developed in this study, through the classical test theory and Mokken analysis with two different sample groups (teachers, N = 337; students, N = 355). The results of the Mokken analysis and the confirmatory factor analysis showed that the UCLA-10 and UCLA-5 were unidimensional and exhibited reliability and convergent validity. In contrast, the UCLA-8 was multidimensional and violated several assumptions of monotonicity and invariant item-ordering, although it showed satisfactory reliability and concurrent validity. All three versions of the scale correlated significantly with other indices of psychological well-being regarding concurrent validity, and the correlation coefficients were comparable to the coefficients of the 20-item version with the same variables. All three versions of the loneliness scale also demonstrated satisfactory convergent and discriminant validity. The results indicated that the UCLA-10 and UCLA-5 can be used as reliable and valid measures when the use of the long version of the UCLA Loneliness Scale is unsuitable.

“…The validity of the instrument was demonstrated through correlations between SWLS scores and other measures of well-being (Diener et al, 1985). In South Africa, the SWLS was used with a student and teacher sample, and the reliability coefficients reported were .89 and .90, respectively (Padmanabhanunni & Pretorius, 2021a; Pretorius & Padmanabhanunni, 2022b).…”

Researchers have paid limited attention to the role of adaptive cognitive appraisals in conferring resilience. In this study, we demonstrate the influence of positive appraisals of problem-solving ability and social support on mental health outcomes. A random sample of students at a university in South Africa ( n = 322) participated in the study. They completed the Perceived Stress Scale, the Multidimensional Scale of Perceived Social Support, the Problem-Solving Inventory, the Beck Hopelessness Scale, and the Satisfaction with Life Scale. Mediation analysis found that problem-solving appraisal and social support jointly and separately mediated the effects of perceived stress on hopelessness. The combined effect of social support and problem-solving appraisal on life satisfaction was significant; however, only social support was found to mediate the relationship between perceived stress and life satisfaction. The findings indicate that adaptive appraisals of self and others are potential sources of resilience that can buffer individuals from the adverse impact of stressful life events.

The current study focused on the role of the sense of coherence (SOC) in the serial relationships among the fear of COVID-19, indices of psychological distress, and life satisfaction. It examined the hypothesis that an SOC would mitigate the impact of the fear of COVID-19 on psychological distress, which in turn would positively impact life satisfaction. Participants were school teachers (N = 355) who completed the Fear of COVID-19 Scale, the trait scale of the State-Trait Anxiety Inventory, the Beck Hopelessness Scale, the short form of the Sense of Coherence Scale, and the Satisfaction with Life Scale. A path analysis confirmed the mediating role of the dimensions of the SOC in the relationships among the fear of COVID-19, indices of psychological distress, and life satisfaction. Specifically, comprehensibility, meaningfulness, and manageability were found to mediate the associations between the fear of COVID-19 and anxiety, and the fear of COVID-19 and hopelessness, which in turn were associated with higher levels of life satisfaction. The findings confirmed that an SOC is an important source of resilience. Interventions that facilitate the re-appraisal of stressors as challenges and enhance the awareness of practical coping strategies can build an SOC and promote mental health.
