Support as a crucial predictor of good compliance of adolescents with a chronic disease.

The purpose of this study was to describe the factors that predict compliance among adolescents with a chronic illness. The data were collected by questionnaires from adolescents with asthma, epilepsy, juvenile rheumatoid arthritis (JRA) and insulin-dependent diabetes mellitus (IDDM). Groups of 300 adolescents with these illnesses were selected from the Finnish Social Insurance Institution's register, giving a total study series of 1200 individuals. The final response percentage was 88% (n = 1061). The data were analysed with the SPSS software. Logistic regression was used to indicate the predictors of good compliance. The compliance of adolescents with a chronic disease was predicted on the basis of support from parents, nurses, physicians and friends, as well as motivation, energy and willpower. The most powerful predictor was support from nurses. The likelihood of adolescents supported by nurses complying with health regimens was 7.28-fold compared to the adolescents who did not receive support from nurses. The next powerful predictor was energy and willpower. Adolescents who had the energy and willpower to take care of themselves complied with health regimens with a 6.69-fold likelihood compared to the adolescents who did not have energy and willpower. Adolescents who had good motivation were 5.28 times more likely to comply than the adolescents who did not have motivation. Support from parents, physicians and friends similarly predicted good compliance with health regimens.
