Abstract

This study examined the effect of patient satisfaction on medication adherence through serial mediation of Self Regulatory Model (SRM) components which are illness perception and beliefs about medicines in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). The 222 outpatients (nRA = 112; nAS = 110) were administered a sociodemographic form, the Medication Adherence Report Scale, the Brief Illness Perception Questionnaire, the Short Assessment of Patient Satisfaction, and the Beliefs about Medicines Questionnaire. The results showed that SRM components fully mediated the relationship between patient satisfaction and medication adherence. This proposed model had acceptable and better fit indices than the alternative model where patient satisfaction was introduced as a direct predictor. Furthermore, patient satisfaction, illness perception, and beliefs about medicines had an extremely good relationship, so these may be interpreted as variables of a latent construct of the illness experience which deserves further research in these group of patients.
