This study is a pretest, posttest, follow-up, randomized controlled experimental study. This study will be conducted at the Health Sciences University Sultan II. Abdulhamid Han Training and Research Hospital, Department of Psychiatry. According to the G-power analysis results, the minimum sample size of the study was calculated as 40 (intervention 20, control 20). Before randomization, the Personal Information Form and P1-P3 questions on the Positive and Negative Syndrome Scale (PANNS) will be applied to the patients in order to identify the patients with early psychosis. Computer-aided https://www.random.org/integers/ program will be used to assign the intervention and control group without bias. It is planned that the intervention group will consist of at least 8 participants and the program will be implemented as three intervention groups. Acceptance and Commitment Therapy (ACT) Based Intervention Program was applied to the intervention group in eight sessions online. Each session will last an average of 60-90 minutes. There will be two sessions for one group per week. The control group will not receive any intervention by the researcher, and participants will continue with their routine treatment plan. The intervention groups after the program is completed and three months later, follow-up will be done by applying the post-test, while the control group will be followed-up by applying the post-test four weeks and three months later.~In the preparation of the interventions and planning of the sessions based on ACT, the researcher utilised studies in the literature and the basic ACT training she had received. After preparation of the ACT intervention protocol, it was given its final shape by obtaining the views of specialists working in this field. The sessions were prepared based on six components of psychological flexibility found at the basis of ACT.
This study is to examine the effect of Acceptance and Commitment Therapy applied to patients in early psychosis patients on psychotic symptoms and functionality levels.
