韓国版高齢者興味チェックリストの妥当性と信頼性に関する研究

Validity and reliability of the Korean Interest Checklist for the Elderly

要旨：本研究の目的は，先行研究から作成した46項目からなる「韓国版高齢者興味チェックリスト」を韓国首都圏在住の242名の健常高齢者を対象に実施し，探索的因子分析による構成概念妥当性と信頼性の検討を行うことである．その結果，「日常生活活動」，「社会的・健康維持活動」，「身体的スポーツ活動」，「観覧的活動」の4つの下位因子構造による構成概念が構築された，しかし，「日常生活活動」と「観覧的活動」では男女の性役割の差が影響された．再検査法による相関係数はすべて有意な相関(r＝0.72〜0.97)であり，4因子構造で構成された28項目のCronbachα係数は0.97と内的整合性の高い信頼性が示された．

　This study aimed at examining the construct validity and test-retest reliability of the Korean Interest Checklist for the Elderly (K-ICE) which the authors established, and which contained 46 items utilizing exploratory factor analysis. The participants were 242 healthy elderly Koreans living in central Korea. The following 4 factors were extracted: Activities for Daily Living (ADL), Social Activities and Maintaining Health Status, Physical Sports Activities and Activities for Watching Sports and Plays (AWSP). ADL and AWSP reflected gender roles. All K-ICE items were significant according to the test-retest correlations (r = 0.72〜0.97). Cronbach's a was 0.97 for 28 items which constructed the 4 factors. In conclusion K-ICE showed high reliability and validity.
