AI Article Synopsis
- The study analyzed the measurement properties of posttraumatic growth items among Black and White Hurricane Katrina survivors, finding similar internal consistency reliability for both groups.
- Confirmatory factor analysis indicated that the items had adequate fit and only minor differences in factor loadings and measurement errors between the two racial groups.
- Mixed results from tests of measurement invariance suggest that while there were some differences, the overall factor loadings and variances were largely comparable, supporting the use of these items in future surveys.
Article Abstract
This study examined the equivalence or comparability of the measurement properties of seven selected items measuring posttraumatic growth among self-identified Black (n = 270) and White (n = 707) adult survivors of Hurricane Katrina, using data from the Baseline Survey of the Hurricane Katrina Community Advisory Group Study. Internal consistency reliability was equally good for both groups (Cronbach's alphas = .79), as were correlations between individual scale items and their respective overall scale. Confirmatory factor analysis of a congeneric measurement model of seven selected items of posttraumatic growth showed adequate measures of fit for both groups. The results showed only small variation in magnitude of factor loadings and measurement errors between the two samples. Tests of measurement invariance showed mixed results, but overall indicated that factor loading, error variance, and factor variance were similar between the two samples. These seven selected items can be useful for future large-scale surveys of posttraumatic growth.

Objectives: Ageism occurs across the world, with negative consequences for individuals and societies. In 2016, WHO received a mandate from its Member States to lead the global campaign to combat ageism. To monitor, evaluate, and build evidence for reducing ageism, the availability of a brief, reliable and valid set of indicators of ageism experiences that can be used globally is essential.

Current practices to screen for financial toxicity are inconsistent because of the lack of a validated and clinically integrated screening tool. This analysis aimed to create and assess an abbreviated version of the validated Comprehensive Score for Financial Toxicity (COST) tool, a measure of financial toxicity used for research purposes, which could easily be added into often-lengthy clinical screening workflows.

Background: Early screening for autism spectrum disorder (ASD) is crucial, yet current assessment tools in Chinese primary child care are limited in efficacy.
Objective: This study aims to employ machine learning algorithms to identify key indicators from the 20-item Modified Checklist for Autism in Toddlers, revised (M-CHAT-R) combining with ASD-related sociodemographic and environmental factors, to distinguish ASD from typically developing children.
Methods: Data from our prior validation study of the Chinese M-CHAT-R (August 2016-March 2017, n = 6,049 toddlers) were reviewed.
