Control perception, illness impact and emotional adjustment in chronic patients

Our aim is to determine the relationships and predictive power of several variables related to control perception construct on illness impact and emotional adjustment. We studied 50 Rheumatoid Arthritis out-patients. Regression analysis showed that the two SIP dimensions, Physical and Psychosocial, were predicted by Perceived Health Competence (R2 =.27, t= - 4.14*** and R2 =.14, t= -2.64**, respectively). Internal Locus was a significant predictor of the Anxiety variable (R2 =.16; t= -3.05**). Finally, Generalized Self-efficacy, in a first step, (R2 =.30; t= -3.30**) and Internal Locus, in a second step, (R2 =.39; t= -2.63**) were significant predictors of Depression. But, only control variables were significant predictors of depression when we controlled the illness impact effect.
