The COVID-19 pandemic represents an unprecedented threat for individuals worldwide. This paper reports the initial psychometric properties for the recently developed COVID-19 Multifaceted Threat Scale. Across three studies the construction and initial psychometric evidence is presented. In Study 1 (n = 194, 11 national groups), we adopted an inductive qualitative methodology to elicit participants’ concerns, worries, or fears about the corona pandemic. A thematic analysis revealed 10 consistent themes around threat, from which we constructed a pool of 100 potential items. In Study 2, a sample from the United States (n = 322) provided data for an exploratory factor analysis which reduced the 100 items to 30 items across the 10 hypothesised dimensions sub-factors. In Study 3, these findings were then ratified in samples from the United States (n = 471) and India (n = 423) using a multi-group confirmatory factor analysis. We also present reliability estimates (internal consistency: Studies 2-3) and preliminary evidence of the validity for the scale across two national groups (United States and India). The evidence presented suggests that the COVID-19 Multifaceted Threat Scale is a psychometrically sound measure and can be used to explore current and long-lasting effects of the pandemic on individuals and societies.

Peer-facilitated support groups are an important source for receiving disease-related information and support for people with systemic sclerosis (or scleroderma). A recent survey explored reasons for attending systemic sclerosis support groups in Europe and Australia and used exploratory factor analysis to group reasons for attendance into three main themes: (1) interpersonal and social support, (2) disease treatment and symptom management strategies, and (3) other aspects of living with systemic sclerosis. The objective of the present study was to replicate this study in a sample of patients from North America using confirmatory factor analysis. A 30-item survey was used to assess reasons for attendance and organizational preferences among systemic sclerosis patients in Canada and the United States. In total, 171 members completed the survey. In the confirmatory factor analysis, the three-factor model showed good fit to the data (χ2(399) = 646.0, p < 0.001, Tucker–Lewis index = 0.97, comparative fit index = 0.97, root mean square error approximation = 0.06). On average, respondents rated 22 (73%) of 30 items as “important” or “very important” reasons for attending support groups. Among organizational preferences, respondents emphasized the importance of the ability to share feelings and concerns, as well as educational aspects. Findings of our study suggest that reasons for attending support groups are similar for patients from Europe, Australia, and North America and that support groups should facilitate social support as well as disease education. These results inform the development of training programs for current and future systemic sclerosis support group leaders across the globe.

This chapter describes the importance of measurement in social research and education research. In order to validly compare across groups, whether it is age, gender, ethnicities, or cultures, measurement invariance needs to be established. This is accomplished through single-group and multi-group confirmatory factor analysis. The procedural approach is presented with a detailed illustration from real research in servant leadership in K-12 principals in the United States. Second-order confirmatory factor analysis is described due to its popularity. Procedural steps are cited, and an example is given for illustration. As a major statistical technique in instrument development, exploratory factor analysis is discussed and illustrated at the beginning of this chapter.

The Kaufman Assessment Battery for Children, Second Edition, measures cognitive processing, includes non-verbal sub-tests, and is increasingly used in low- and middle-income countries. While the Kaufman Assessment Battery for Children, Second Edition, has been validated in the United States, a psychometric evaluation has not been conducted in Southern Africa. This study aims to establish the reliability and validity of the Kaufman Assessment Battery for Children, Second Edition, among a sample of 376 primary school-aged children in rural South Africa (7–11 years). We examined Cronbach’s alpha and conducted a confirmatory factor analysis. The battery showed good reliability (mental processing index [α = .78]), and the originally validated structure of the Kaufman Assessment Battery for Children, Second Edition, was maintained (χ2 = 16.30, p = .432). Mean scores were low on the Planning sub-scale. On the Simultaneous sub-scale, the mean score was higher for the supplementary sub-test Block Counting versus the core sub-test Triangles. With translation and the inclusion of supplementary sub-tests, the Kaufman Assessment Battery for Children, Second Edition, is an appropriate assessment to use in this context (150/150).
