Abstract
The brief version of the Post-Secondary Student Stressors Index (Brief-PSSI) was developed in order to improve the usability of the instrument as a method for evaluating the severity and frequency of stressors faced by post-secondary students. While the original 46-item instrument has been thoroughly psychometrically validated and successfully used among student populations, the length of the instrument limits its utility. Providing a valid, shortened version of the PSSI will enable institutions to include the tool on existing online surveys currently being deployed to surveil the mental health and wellbeing of their students. This study reports preliminary evidence in support of the validity and reliability of the Brief-PSSI using a cross-sectional pilot sample of students attending an Ontario university in 2022. A total of 349 participants (average age 25 (SD = 7.7), range 19–60) completed the first survey, while 149 completed the follow-up survey (average age of 26 (SD = 7.7), range 17–60). Evidence of internal structure, relations to other variables, and of test-retest reliability was assessed according to established index validation guidelines, including the specification of multiple-indicator, multiple-cause models, and Spearman’s rho correlation coefficients. Results provide preliminary support for the validity and reliability of the tool, which demonstrated acceptable goodness-of-fit statistics, statistically significant relationships with like constructs in the hypothesized directions, and good test-retest reliability correlation coefficients. The Brief-PSSI is a useful tool for evaluating the sources of stress among post-secondary students, assessing both the severity of stress experienced and frequency with which each stressor occurred. Future research should explore the practical utility of adding the Brief-PSSI to existing survey assessments as well as pursue the continued collection of validation evidence for the tool among varied student populations.
