Preliminary Validation of a Short Form of the Perceived Stress Questionnaire for Use in Clinical Rehabilitation Counseling Research and Practice
BackgroundThe purpose of this study was to develop and validate a short form of the Perceived Stress Questionnaire (PSQ) in people with spinal cord injury (SCI).MethodsThe sample consisted of 274 individuals with SCI. Measures administered were the PSQ-20, Center for Epidemiological Studies-Depression Scale, and Rand Short-Form 36 General Health Scale.ResultsResults showed that after selecting two items from each subscale of the PSQ-20, factor analysis results supported a unidimensional measure for the PSQ-8. The PSQ-8 total score demonstrated a high correlation with the PSQ-20 total score. The reliability of the PSQ-8 was adequate and similar to the PSQ-20. The PSQ-8 measurement correlated well with the external correlates of depression and health status. The mediation analysis indicated depression as a partial mediator for the relationship between perceived stress and health status, indicating people with higher levels of perceived stress had poorer health outcome in this study.ConclusionsThis study provides evidence to support the psychometric properties of PSQ-8 in people with SCI. The PSQ-8 is a brief, reliable, unidimensional, and psychometrically sound measure of perceived stress that can be used in clinical rehabilitation and mental health counseling research and practice.
