Correlates of Functional Disability in Patients With Postural Tachycardia Syndrome: Preliminary Cross-Sectional Findings.

The study investigated correlates of functional disability in 94 patients (89.4% women, 10.6% men; mean age=34.2 years) with postural tachycardia syndrome (POTS), a clinical syndrome of orthostatic intolerance characterized by significant functional limitations. Path analysis supported a model in which, controlling for demographic and disease variables, catastrophic cognitions were directly related to the latent variable functional disability, whereas somatic vigilance, anxiety sensitivity, and neuroticism were indirectly associated with functional disability through their relationship with catastrophic cognitions. Results suggest that modifiable psychological factors play a role in the functional limitations experienced by patients with POTS. Longitudinal research is necessary to confirm these relationships.

Body image dissatisfaction among women with scleroderma: Extent and relationship to psychosocial function.

Body image dissatisfaction and its relationship to psychosocial function were investigated in 127 women with scleroderma. Results indicated elevated body image dissatisfaction, with participants reporting higher levels than a sample of patients with severe burn injuries. Age, skin tightening above the elbows, and functional disability were related to heightened body image dissatisfaction, suggesting that younger patients with more severe disease may be at greatest risk for developing body image concerns. Path analysis revealed that depression mediated the relationship between body image dissatisfaction and psychosocial function. Results suggest that body image dissatisfaction is a significant concern in women with scleroderma and should be assessed routinely. Early identification and treatment of body image dissatisfaction may help prevent the development of depression and psychosocial impairment in this population.
