Objective: To determine the prevalence and associated factors of medication nonadherence among children and adolescent psychiatric patients at Nakhon Nayok Hospital.

Method: A cross-sectional descriptive study was conducted on 71 children and adolescent psychiatric patients aged 5 - 18 years old. The sample population were patients at the child and adolescent psychiatry out-patient clinic at Nakhon Nayok Hospital from January to April 2022. The demographic data and the medication histories of both the parents and their children were collected and analysed.

Result: From the analysis of the 71 subjects (63.4% were male) with a mean age of 11.9±4.1 years. Most were studying at the secondary school level (50.7%) and were diagnosed with attention deficit hyperactivity disorder (56.3%). The most prescribed medication was methylphenidate (56.3%) and the average duration of the treatment was 20.0±14.9 months. The prevalence of medication nonadherence was 49.3%. The most common causes of medication nonadherence were forgetfulness (28.1%), unattendance to follow up the appointment (21.1%) and refusal to take medication (15.5%), respectively. Medication adherence were statistically significant with age 5 - 10 years (p-value = 0.03) and were resident in Nakhon Nayok Province (p-value = 0.03). Factors associated with medication nonadherence were not found.

Conclusion: The results should be used to determine risk factors and to develop tools to improve medication adherence in child and adolescent psychiatric patients.
