Purpose: To (i) investigate the influence of general self-efficacy on quality of life outcomesover time among adolescents with type I diabetes or juvenile rheumatoid arthritis (JRA), (ii)investigate parents’ perceptions of general self-efficacy and quality of life of adolescentswith diabetes or JRA over time, and (iii) identify possible differences in the evaluations ofadolescents and parents.

Methods: This study included adolescents aged 12–25 years with type I diabetes or JRAand their parents. At T1, 171/573 (30% response rate) adolescents with diabetes or JRAand 229/563 (41% response rate) parents completed the questionnaire. At T2, 230/551(42% response rate) adolescents and 220/559 (39% response rate) parents still participat-ing in the study completed the questionnaire. A total of 112 adolescents and 143 parentsfilled in the questionnaires at both T1 and T2.

Results: Adolescents perceived significant improvement in their general self-efficacy and reduced quality of life over time, whereas parents’ perceptions did not change. Accordingto adolescents and parents, physical functioning was better among adolescents with dia-betes than among those with JRA. Regression analyses of adolescents’ data showed thatgeneral self-efficacy at T1 (bD0.13;p0.10) and changes in general self-efficacy (bD0.22;p0.01) predicted quality of life at T2. Parents’ responses revealed that adolescents’ gen-eral self-efficacy at T1 (bD0.16;p0.05) and changes in adolescents’ general self-efficacy(bD0.18;p0.05) predicted adolescents’ quality of life at T2.

Conclusion:General self-efficacy and changes therein positively affected quality of life inadolescents with diabetes or JRA over time, as perceived by adolescents and parents.These findings emphasize the need for the implementation of interventions aiming to improve general self-efficacy in these populations
