Abstract: Clinical applications of psychedelic substances and Psychedelic-Assisted Therapy (PAT) are areas of growing interest that also raise significant social concerns. Despite existing controversies and legal restrictions, empirical research on the use of psychedelic substances, such as psilocybin, mescaline, MDMA, LSD, DMT, and ibogaine, in the treatment of conditions including treatment-resistant depression, post-traumatic stress disorder (PTSD), existential anxiety, and substance use disorders is developing. Such research is also being conducted in Poland. Legislative processes underway in several countries in Europe, the United States, Canada, and Australia suggest that Psychedelic-Assisted Therapy (PAT) may be incorporated into clinical practice in the future. In a previous study on attitudes toward psychedelics and their therapeutic use among mental health professionals in Poland, questionnaires measuring attitudes toward psychedelics (APQ, COPS), attitudes toward evidence-based practice (EBPAS-15), trust in science (Trust in Science Short Scale), and other cognitive and existential factors were used. Using instruments in a subsequent study whose psychometric properties have not yet been sufficiently examined in the Polish population provides an opportunity to evaluate them in a separate study sample. The assessment of the psychometric properties of measurement instruments is important for determining the extent to which the scores obtained using them are reliable and valid, and whether the instruments can be used in further research. In particular, it is important to examine the properties of the Polish versions of the questionnaires in a sample of psychology students, who constitute a group of future mental health professionals. The aim of the study is to assess selected psychometric properties of the Polish versions of the APQ and EBPAS-15 in a sample of psychology students. The study will focus on evaluating the measurement properties of instruments assessing attitudes toward psychedelics and their therapeutic use and attitudes toward evidence-based practice. The main research questions are: - Do the Polish versions of the APQ, EBPAS-15 demonstrate satisfactory psychometric properties in a sample of psychology students? -Do the individual questionnaires, APQ and EBPAS-15, demonstrate satisfactory reliability? - Are the scores obtained using the questionnaires associated in ways consistent with theoretical expectations? - Can distinct profiles of students be identified based on their scores on the questionnaires measuring attitudes toward psychedelics and attitudes toward evidence-based practice? - What attitudes toward psychedelics and their therapeutic use do psychology students hold? The study will be anonymous and conducted online using standardized questionnaires and a self-developed survey. The results may contribute to a better understanding of the psychometric properties of the Polish versions of the questionnaires used in a sample of psychology students and to an assessment of their usefulness in further research on attitudes toward psychedelics and their therapeutic use, attitudes toward evidence-based practice, and trust in science. They may also provide data on the attitudes of future mental health professionals toward psychedelics and their therapeutic use.
