MEDICATION ADHERENCE IN PSYCHIATRY: A COMPARATIVE ANALYSIS OF THEORETICAL EXPLANATORY MODELS. PART ONE: CONCEPTUAL, MULTIDIMENSIONAL, AND SOCIOCOGNITIVE APPROACHES

Abstract

The present study constitutes the first part of a comprehensive comparative analysis of theoretical explanatory models of medication adherence in psychiatry. It examines the conceptual evolution from compliance to adherence and concordance, as well as the applicability of the World Health Organization’s multidimensional framework, the Health Belief Model, and the Theory of Planned Behavior. Particular emphasis is placed on the ways in which these approaches explain the transition from passive patient participation to active and actual therapeutic behavior. The first part provides the conceptual foundation of the analysis through broader models of health behavior in medicine, psychiatry, clinical psychology, and health psychology. The second part presents additional models addressing subjective representations of illness, beliefs about medication, behavioral change, the therapeutic alliance, and shared decision-making.
