TTM-Based Social Media Psychoeducation for Psychosis

Condition(s) studied

Investigational drug(s) / intervention(s)

TTM-Based Online Psychoeducation Program: A 5-week structured psychoeducation program based on the Transtheoretical Model (TTM), delivered via WhatsApp. Educational content was tailored to the participant's stage of change and included videos, texts, and interactive materials to promote treatment adherence in individuals with psychosis.

Standard Face-to-Face Psychoeducation Program: A 3-week conventional psychoeducation program delivered face-to-face at the Community Mental Health Center. The program focused on general treatment adherence without utilizing the Transtheoretical Model and included verbal education, printed materials, and discussions.

TTM-Based Online Psychoeducation Program: The intervention was provided after a 3-month delay following initial observation. Participants received the same 5-week online psychoeducation program as the main intervention group

Study summary

This doctoral research investigates the effect of a Transtheoretical Model (TTM)-based psychoeducation program delivered via social media on treatment adherence in individuals diagnosed with psychosis. The study follows a randomized controlled trial design with pretest, posttest, and three-month follow-up assessments.

A total of 60 participants were selected from among 354 individuals registered at the Balıkesir Community Mental Health Center (CMHC), based on predefined inclusion and exclusion criteria. Participants were randomly assigned into three groups:

1. an online intervention group receiving a 5-week TTM-based treatment adherence psychoeducation program via WhatsApp;
2. a face-to-face intervention group receiving a standard, non-TTM-based treatment adherence psychoeducation program over 3 weeks at the CMHC; and
3. a control group that received no educational intervention, only assessments.

Data collection instruments include a Sociodemographic Information Form, the Stage of Change Identification Form, the Medication Adherence Report Scale (MARS-5), and the Clinical Global Impression-Severity Scale (CGI-S). Measurements were conducted at baseline, post-intervention, and three months after the intervention.

The study hypotheses are:

Research Hypotheses H1: The treatment adherence scale scores of individuals diagnosed with psychosis who participate in the TTM-based psychoeducation group administered via social media will differ compared to the scores of individuals who participate in the face-to-face treatment adherence psychoeducation group.

H2: The treatment adherence scale scores of individuals diagnosed with psychosis who participate in the TTM-based psychoeducation group administered via social media will differ compared to the scores of individuals who do not receive TTM-based psychoeducation.

This study aims to provide evidence for the efficacy of theory-based, technology-supported psychoeducation programs in enhancing treatment adherence among individuals with psychosis. Furthermore, it evaluates whether a model-based online psychoeducation program is more effective than a conventional treatment adherence education.

Eligibility

Primary outcome measure(s)

• Medication Adherence (Treatment adherence) — Baseline (Week 0) and Post-Intervention (Week 5)
  Score on a 5-point Likert scale
• Change in Medication Adherence Scores (MARS-5) — Baseline, Post-Intervention (Week 5), and 3-Month Follow-Up
  Medication adherence will be assessed using the 5-item Medication Adherence Report Scale (MARS-5), originally developed by Horne and Hankins (2001). It is a generic, self-reported Likert-type scale validated across various chronic physical and psychiatric conditions, including bipolar disorder, hypertension, asthma, and schizophrenia. Each item is rated on a 5-point scale from 1 (always) to 5 (never), yielding a total score between 5 and 25. Higher scores indicate better adherence. The Turkish version of the scale was adapted by the investigators and demonstrated acceptable internal consistency (Cronbach's α = 0.78). Factor analyses supported a unidimensional structure (KMO = 0.79; CFI = 0.97; RMSEA = 0.089), consistent with the original. In this study, MARS-5 will be administered at three time points: prior to the intervention (baseline), immediately following the intervention (post-test), and three months after the intervention (follow-up) to assess changes in treatment adherence
