Exploring Physical Self-Perceptions Among Survivors of Adolescent and Young Adult Cancer

This study explored the factor structure of four subscales from the Physical Self-Description Questionnaire-Short Form (PSDQ-S). Associations between subscales and personal and medical factors were also examined. The analytic sample consisted of 89 survivors of adolescent and young adult cancer (M_{age at time of study} = 32.96 ± 4.37 years; M_{age at diagnosis} = 31.16 ± 4.84 years; 75.3% female). Confirmatory factor analysis suggested a reasonable fit to the data, indicating that the PSDQ-S subscales examined could be used in future investigations with this population [χ²(38) = 46.9, p = 0.15; Root Mean Square Error of Approximation = 0.05, 90% confidence interval = 0-0.10; Comparative Fit Index = 0.97; Standardized Root Mean Square of the Residuals = 0.07]. Multiple linear regressions showed that personal and medical factors accounted for a significant amount of variance in the body fat subscale, with female sex and higher body mass index being significantly associated with lower positive perceptions about the amount of one's body fat. More research examining the factor structure of the PSDQ-S subscales is warranted, and future investigations exploring personal, medical, and modifiable factors associated with physical self-perceptions should be conducted.
