QOL-23. MEASURING BODY FUNCTIONALITY APPRECIATION IN PATIENTS WITH PRIMARY BRAIN TUMORS

Abstract BACKGROUND Body image is a multifaceted construct consisting of thoughts, feelings, and perceptions about one’s body and its functioning. Perception of one’s own physical functioning and capabilities may be an important consideration in neuro-oncology given the sequalae of brain tumors and associated treatment; however, it is understudied in this population. One brief measure of body image, the Functionality Appreciation Scale (FAS) is a comprehensive tool, focused on one’s perceived physical functioning and capabilities, rather than perceived appearance. We aimed to examine the psychometric properties of the recently developed Functionality Appreciation Scale (FAS) among patients with primary brain tumors. METHODS Adult patients with primary brain tumors (N=237) completed the FAS and other measures of psychological distress as well as medical and demographic characteristics. An exploratory variance factor analysis (EFA) using principal axis factoring and a Promax rotation was conducted. Convergent validity was examined via correlations to measures of psychological distress. RESULTS The EFA supported the single-factor structure, which accounted for 62.71% of the variance with all items loading significantly onto this factor. The FAS had good internal consistency (Cronbach’s a=.90). Convergent validity was demonstrated by negative associations (ps<.05) with symptoms of depression (r=-.30), generalized anxiety (r=-.21), and death anxiety (r=-.17). CONCLUSION Results confirmed the single factor structure of the FAS in primary brain tumor patients. Furthermore, the expected negative relationships with measures of psychological distress provide evidence of convergent validity. The FAS is valid and reliable in patients with primary brain tumors. Our findings suggest that body functionality and appreciation may be important to target in psychosocial interventions for those with primary brain tumors.
