Abstract

The purpose of this study was to develop a scale to assess suicidal inclination of college students (SSI) based on the scale of suicidal inclination for junior high school students. The first step involved creating a provisional scale by modifying the original items. In this study, 261 college students completed SSI. The second step aimed to test the factor structure of SSI, and to select the final items. Factor analysis with varimax rotation indicated five factors: (a)physical and mental health problems, (b)depressive mood, (c)suicidal inclination, (d)low volition, and (e) with for loneliness consisting of 22 items. For these factors, Cronbach's alpha coefficients ranged from .40 to .73. The construct validity of SSI was investigated with three subscales of a scale of attitude toward death in adolescence (intention to live out own life, fear of death, meaning of death for life), and the criterion-related validity of SSI was investigated with the Center for Epidemiologic Studies Depression Scale. Finally, SSI with 22 items demonstrated internal consistency, and construct and criterion-related validity.
