多次元ソーシャルサポート測定尺度の作成とカットオフ値の設定に関する研究

抄録

This study aims to (a) develop the multi-dimensional social support measurement scale and (b) establish and examine the validity of cut-off values for the amount of support (support ratio, support difference, amount of received support) in each support type. We analyzed data from 1,070 Japanese undergraduates and developed a scale consisting of three dimensions: tangible support, informational support, and emotional support. Each support type scale showed sufficient reliability. Validity was generally confirmed when utilizing the support ratio and support difference as measures. However, the amount of received support requires further validation. Next, an ROC analysis was conducted to establish cut-off values for the amount of each support type. Then, support was classified as under-, adequate-, and over-support. We also examined the validity of these cut-off values. The results revealed generally good accuracy for the cut-off values of each support amount for each support type. For the lower and upper cut-off values, the support difference and amount of received support, respectively, had the highest accuracy.
