Assessment of self-control behavior: validity analyses on a Japanese version of the self-control schedule.

To investigate the validity of a Japanese translation of Rosenbaum's Self-Control Schedule (SCS), 338 Japanese undergraduates were administered the scale. Construct validity of the SCS subscales, Constructive Self-Control and Ineffective Self-Control, in this study was achieved by correlations with coping responses. In addition, multiple regression analyses showed that Constructive Self-Control contributed to a negative prediction of future depression and psychosomatic symptoms, and Ineffective Self-Control predicted future depression and psychosomatic symptoms. These findings indicated that the Japanese version of the SCS employed in this study appeared to be a valid and promising measure of self-control.
