The effect of interpersonal relations theory-based motivational interviews on functional remission and insight levels of patients with schizophrenia: A randomized controlled trial

Background: Using therapeutic techniques and conducting motivational interviews in communication with patients with schizophrenia increases individuals' functional remission, insight, and motivation levels.Aim: This single-blind, randomized controlled study examines the effect of Interpersonal Relations Theory-Based motivational interviews on functional remission and insight levels in patients with schizophrenia.Methods: The participants of this study were 40 patients with schizophrenia randomly assigned to either the experimental or control groups (20 in each group). The researchers carried out a 6-session Interpersonal Relations Theory-based motivational interview with the participants in the experimental group. Study data were collected using a demographic questionnaire, the Functional Remission of General Schizophrenia Scale (FROGS), and the Scale for Assessing the Three Components of Insight (SAI).Results: Social Functioning, Health and Treatment, Daily Living Skills, and SAI scores of the individuals in the intervention group were statistically higher than those in the control group (p < 0.05) in the post-intervention and follow-up measures. There was a positive and significant correlation between the post-intervention Social Functioning, Health and Treatment, Daily Life Skills, and total FROGS scores and the SAI score of the individuals in the intervention group (p < 0.05).Conclusions: It was concluded that motivational interviews based on Interpersonal Relations Theory were effective in increasing the insights and functionality of patients with schizophrenia. Psychiatric nurses' practice of motivational interviews based on the therapeutic relationship is considered to increase the quality of care and satisfaction of patients with schizophrenia. It is recommended that this practice be used extensively in clinical practice.
