Brief summary
This quasi-experimental two-group pretest-posttest study examined the effects of an interpersonal communication skills training program on medication adherence in patients with schizophrenia, measured at pre-intervention, post-intervention, and one-month follow-up. Research Hypotheses 1. The experimental group receiving the interpersonal communication skills training program will show higher mean treatment adherence scores post-intervention and at one-month follow-up compared to baseline. 2. The experimental group will show higher mean treatment adherence scores post-intervention and at one-month follow-up than the control group receiving routine nursing care.

BEHAVIORALInterpersonal Communication Skills Training Program
This program was developed based on DeVito's communication theory and integrated with the positive reinforcement-based interpersonal communication training developed by Thiengwiriyakul et al.(11) This program was evaluated by a panel of three experts-a psychiatrist, a psychiatric nurse, and a psychiatric nursing academic-who assessed content relevance, appropriateness, and language clarity. After revisions based on their feedback, the program achieved a Content Validity Index (CVI) of 0.93, exceeding the acceptable threshold.

| Medication Adherence Behavior | Before the intervention, Immediately after the intervention , 1 month follow-up | Treatment adherence refers to the extent to which patients with schizophrenia follow their prescribed medication regimen, assessed using the 16-item Treatment Adherence Behavior Assessment Scale (Uthaipan & Daengdomyut, 2013) It has been validated for content with a content validity index (CVI) of 0.88 and demonstrates good reliability with a Cronbach's alpha of 0.85. It consists of 16 items rated on a 4-point Likert scale (Always, Often, Occasionally, Never), divided into two parts: 1) Items 1-8: behaviors related to medication adherence. 2) Items 9-16: abilities to recognize and manage side effects. Seven items are negatively worded (Items 1, 2, 3, 7, 8, 12, 15), and nine items are positively worded (Items 4, 5, 6, 9, 10, 11, 13, 14, 16). The scoring is interpreted as follows: 1) ≤ 21 points: Low adherence 2) 21-42 points: Moderate adherence 3) ≥ 43 points: High adherence |
