AimDecreased participation and complex transitions into adulthood among youth with disabilities may impede their well-being. To advance knowledge on the co-occurrence of mental health problems and physical disability, this brief report describes the frequency of mental health problems, measured by the Behavior Assessment System of Children (BASC-3), among transition-aged youth (14–25 years) with physical disabilities and examines the association between mental health problems and sex, age, and number of functional issues.MethodsThirty-three participants completed a demographic questionnaire and the BASC-3. Frequency of BASC-3 scales falling within 3 categories: “within norms”, “at risk”, and “clinically significant” were described. Crosstabs and Chi-square tests were used to examine the association between BASC-3 scales and sex, age (< and ≥ 20), and number of functional issues (< and ≥ 6).ResultsOverall, “somatization”, “self-esteem”, “depression” and “sense of inadequacy” were the most common subscales being at risk. Participants with a higher number of functional issues (≥6) were more likely to fall within “at risk” or “clinically significant” categories across 20 (out of 22) BASC-3 scales, and female participants tended to fall more within “at risk” or “clinically significant” categories for 8 of BASC-3 scales. Younger participants (<20) were ranked in the “at risk” or “clinically significant” categories for 7 scales.ConclusionsFindings lend further support for the occurrence of mental health problems emerging in youth with physical disabilities and highlight initial trends especially across functional levels. Further investigation of such co-occurrences and the factors that affect their development is needed.
