作業療法学科の学生におけるコミュニケーションスキル自己評定尺度の開発

Development of the Communication Skills Scale for occupational therapy students in Japan

要旨：作業療法学科在籍中の学生におけるコミュニケーションスキル自己評定尺度を開発することを目的とした．学生259名中，有効回答のあった176名を分析対象とした．得られた結果をもとに探索的・確証的因子分析を実施し，最終的な項目数は29項目，5因子が抽出された．第1因子「関わり合いの導入」，第2因子「非言語的行動の読み取り」，第3因子「非言語的行動の表出」，第4因子「他者への同調」，第5因子「緊張場面の処理」と命名した．これらの尺度は高い内部一貫性を示した（Cronbachのα係数＝.902）．この尺度の活用により，学生が留意すべきスキル不足があらかじめ認識可能となり，作業療法の提供がより効果的に行えるようになると予想される．

　The purpose of this study was to develop a self-rating scale to measure communication skill for Japanese occupational therapy students. The participants were 259 occupational therapy students and the data from 176 occupational therapy students were used for factor analysis. 43 items of this scale were made, and participants answered the questionnaire. We conducted exploratory factor analysis with promax rotation. Construct validity was determined using confirmatory factor analysis, and internal consistency was assessed using Cronbach's alpha. The final instrument was composed of 29 items and the exploratory analysis yielded 5 factors: (1) introduction of the relations, (2) interpreting of non-verbal behavior, (3) expression of non-verbal behavior, (4) agreement with others and (5) addressing the alleviation of tension. The scales showed high internal consistency (Cronbach's alpha = 0.902). Using confirmatory factor analysis, the 5 factor model provided the best fit (chi-square = 21.313, GFI = 0.953, CFI = 0.922, RMSEA = 0.137). The above self-rating scale to measure communication skill for occupational therapy students has adequate reliability and validity. The scale has potential to measure communication skill for occupational therapy students. Further examination of the scale with a large sample size is needed.
