The principal aim of the research is to present the results of PETiT research, as well as to make comprehensive analysis of patient’s adherence from their perspective. Methods: The PETiT test (Personal Evaluations of Transitions in Treatment) was used as research method and was distributed through online communication channels. A total of 479 surveys was satisfactory completed in accordance with authors’ defined criteria. Results: The research results are presented in a table with appropriate descriptions. According to the research results, the respondents are highly educated, display a positive attitude and view of life, and they do not have difficulties for daily activities and professional obligations. Simultaneously, a considerable number of respondents specified they were not adherent, although, they expressed a positive attitude regarding the impact of the drug. Conclusion: The potential cause of the poor adherence level may be an inadequate level of awareness and education related to the adherence role and importance to the outcome of treatment. Increased research and analysis of the key factors influencing patient’s nonadherence are needed, especially those under the influence of the patient.
