Implementation of the evidence-based practice in psychology in Ukraine: Prediction model development [Author Accepted Manuscript]

Objective: By 2021, researchers reported limited access to evidence-based mental health interventions in Ukraine, which became more crucial after the 2022 Russian invasion of Ukraine. Evidence-based practice in psychology (EBPP) requires professionals to consider equal contributions of the best available research, practical experience, and the context of the unique client. This study aimed to reveal the possible predictors of EBPP implementation among Ukrainian psychologists (n=366) by developing and testing multivariable prediction models. Methods: The research design followed the methodology of “Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis” — TRIPOD checklist. The online survey included a questionnaire on sociodemographic characteristics, educational and professional background, and a purposely developed part regarding the knowledge, attitudes, and utilization of the EBPP approach. Results: Regression analysis revealed different prediction models for the belief that the respondent implements EBPP and the intensity of EBPP elements implementation, explaining 24.4% and 18.5% of their variance with 3 and 5 predictors, respectively. Conclusion: Psychologists believed they were implementing EBPP when they used interventions/methods with proven efficacy, were members of psychological associations, and assessed their knowledge regarding EBPP higher. However, more intensive use of EBPP elements was predicted by a psychologist’s experience in personal therapy and supervision, a positive attitude toward EBPP elements, membership in a psychological association, and a perceived level of knowledge regarding EBPP. The belief that the psychologist’s practice aligns with the EBPP requirements and the intensity of using EBPP elements had a rather moderate correlation.
