The Chinese version of the Parenting Stress Index: a psychometric study

This study examined the psychometric properties of a Chinese version of the Parenting Stress Index/Short Form (PSI/SF). A 15-item simplified PSI/SF (S-PSI/SF) was subsequently developed which maintained a level of reliability and validity similar to the full version. The Chinese PSI/SF was tested on 149 parents (100 mothers, 49 fathers) of pediatric cancer patients in Taiwan. Psychometric testing was conducted using item analysis, Cronbach's alpha and confirmatory factor analysis. The S-PSI/SF was constructed based on the item analysis of the PSI/SF. Both the PSI/SF and S-PSI/SF produced good reliability coefficients. Confirmatory factor analyses indicated that both PSI/SF and S-PSI/SF met all criteria for goodness of fit. Compared with the PSI/SF, the S-PSI/SF demonstrated better internal consistency and overall fit at the one-subscale level, and satisfactory overall fit at two- and three-subscale levels. Despite the limited number of items included, the S-PSI/SF had a very good factor structure. No gender difference in parenting distress index was observed between mothers and fathers of pediatric cancer patients. Conclusion: The 15-item S-PSI/SF is a brief, easily administered instrument that has evidence of reliability and validity in Taiwanese parents of children with cancer. It could serve as a valuable assessment tool in clinical practice to identify parenting stress with a need for intervention.
