摘要：Since its inception, the Strain Theory of Suicide has been tested and supported in a number of empirical studies. This social psychological theory can be employed as a complementary conceptualization to account for suicidal behaviors as well as mental disorders. However, the lack of consistent measurements of the strains limits the application of the theory in scientific research. Our research team has developed such scales for future testing of the Strain Theory of Suicide in a more systematic approach. For the initial items to measure the four strains (value, aspiration, deprivation, and coping), we solicited approximately 40 items for each strain with high face validity by about 30 fellow researchers. A preliminary examination of about 160 items for consistency and validity, with a sample of about 300 college students, yielded 20 consistent items for each of the four strain scales. Then, a second study was conducted at a different university with approximately 500 students to further streamline each of the four strain scales and test the validity of each with corresponding established scales and variables. As a result, 15 items were selected for each of the four Psychological Strain Scales (PSS). In correlation and multiple regression analyses, we found support for the hypotheses regarding the positive associations between psychological strains measured by the PSS and psychopathology including suicidal ideation. Follow up research with the new scales needs to be carried out in order to test the effects of psychological strains on suicide and mental disorders for various populations.
