Korean translation and validation of the Community Commitment Scale for preventing social isolation in older adults

초록

AimThe Community Commitment Scale was developed in Japan to measure communities' ability to prevent older adults' social isolation, including socializing and belonging in the community. We translated the scale into Korean (the Community Commitment Scale-Korean version [CCS-K]), and determined its internal consistency, concurrent validity and construct validity. MethodsSelf-report questionnaires were administered to 326 local volunteers (82.8% women, 65.3% aged 60 years) in Korea. Internal consistency was analyzed with Cronbach's alpha. To evaluate the concurrent validity of the CCS-K, we used the Brief Sense of Community Index, the revised Generative Concern Scale and ratings of two questions that addressed helping elderly neighbors. ResultsThe Cronbach's alpha coefficient for the CCS-K was 0.68. The correlation coefficients between the CCS-K and Brief Sense of Community Index or Generative Concern Scale, were 0.40 and 0.33 (P < 0.001), respectively. ANOVAs comparing the CCS-K between confidence levels for the two questions that addressed helping elderly neighbors showed large or medium-sized relationships ((2) = 0.14 and (2) = 0.08). A confirmatory factor analysis showed the CCS-K had adequate fit to the data (goodness of fit index = 0.965, adjusted goodness of fit index = 0.934, comparative fit index = 0.956 and root mean square error of approximation = 0.067). ConclusionsThe CCS-K has acceptable internal consistency, concurrent validity and construct validity among Korean local volunteers. Thus, we can conclude that the CCS-K can be effectively applied.
