Psychometric properties of the Korean adaptation of the communities advancing resilience toolkit (CART) assessment survey

Abstract

Aims: This study aimed to establish a cross-cultural adaptation of the Communities Advancing Resilience Toolkit (CART) assessment survey for Korean communities (K-CART) and evaluated its psychometric properties of K-CART.

Design: A cross-sectional study design was used.

Methods: A forward and backward translation of the CART was conducted. The psychometric properties of K-CART were evaluated with test-retest reliability, internal consistency, content validity and construct validity. A field study was conducted involving 315 older adults in Pohang city, South Korea from January to March, 2019. Two versions of K-CART were analysed, based on the four-factor and the expanded five-factor K-CART.

Results: The test-retest reliability and internal consistency were acceptable (intraclass consistency coefficient = .90). The consistency reliability was satisfactory (Cronbach's α = 0.91). The content validity index (CVI) was found to be acceptable; wherein the item-CVI and scale-CVI were both 0.95. Confirmatory factor analysis confirmed that the construct validity of the expanded K-CART with five factors reached a more acceptable model fit (χ2 /df = 2.27, CFI = 0.89, TLI = 0.86, RMESA = 0.05).
