Motivation as a crucial predictor of good compliance in adolescents with rheumatoid arthritis.

The purpose of this study was to identify the predictors of compliance shown by adolescents with juvenile rheumatoid arthritis (JRA). Three hundred individuals aged 13-17 years were randomly selected from the Finnish Social Insurance Institution's register. The questionnaires were sent to the adolescents selected from the register to be returned directly to the researcher in a self-addressed envelope. Ninety-one per cent (n = 274) returned the questionnaire. Logistic regression was used to find the factors that predicted compliance with health regimens. The compliance of adolescents with JRA was predicted on the basis of motivation, fear of acute problems, support from nurses, energy and willpower, and threat to social well-being. The most powerful predictor was motivation. The likelihood of the adolescents who had good motivation to comply with health regimens was 29.13-fold compared to the adolescents who did not have good motivation. The next powerful predictor was fear of acute problems. The adolescents who felt fear of acute problems complied with health regimens with a 20.35-fold likelihood compared to the adolescents who did not have fears. The third powerful predictor was support from nurses. The likelihood of adolescents supported by nurse to comply with health regimens was 17.03-fold compared to the adolescents who did not receive support from nurses. The likelihood of adolescents who had energy and willpower to comply with health regimens was 7.56-fold compared to the adolescents who did not have energy and willpower. Also, the threat to social well-being predicted good compliance.
