Objectives: This study aimed to investigate the medication adherence rate and related factors in chronic schizophrenia.
Methods: A total of 65 (34 male and 31 female) outpatients with schizophrenia and with less than 5 years schizophrenia treatment were randomly selected to participate in the study survey. Medication adherence rate was evaluated by counting remaining tablets. The Korean version of Drug Attitude Inventory-10 (KDAI-10) was used to determine the subjective adherence rate. Adherence was defined as a patient taking more than 80% of their total prescribed medication. Positive KDAI-10 scores indicate good adherence.
Results: The rate of good adherence was 87.7%. Our analysis showed that an older age (r=0.323, p=0.009), longer duration of illness (r=0.296, p=0.017), employment (F=4.41, p=0.016), remaining married (F=5.26, p=0.008), and being supported by family members, especially spouse or siblings (F=3.02, p=0.025) were significantly associated with good adherence. Presence of symptoms such as delusion (p=0.033) and hallucination (p=0.032) were related to poor adherence.
Conclusion: The results indicate that future study should investigate patient characteristics associated with medication adherence and analyze the clinician/patient alliance and its affect on adherence. The results also show that further studies might be useful in developing and validating measures of adherence, as well as in designing and evaluating interventions to improve adherent behaviors.
