Exploring the Role of Motivation in the Sustainability of Substance Abstinence Behaviors Among Individuals Undergoing Treatment

Abstract

This study aimed to explore the dimensions of motivation and its role in sustaining substance abstinence behaviors among individuals undergoing treatment. This qualitative study employed thematic analysis. Data were collected through semi-structured interviews with 23 individuals receiving addiction treatment in Tehran rehabilitation centers. Participants were selected through purposive sampling until theoretical saturation was achieved. Data analysis followed Braun and Clarke’s thematic approach using NVivo software. Three main themes emerged: internal motivation, external motivation, and barriers to motivation sustainability. Subthemes such as meaning and purpose in life, self-efficacy, family support, treatment supervision, social pressures, psychological disorders, and stigma were central to motivational experiences. Participants emphasized internal motivation as critical for long-term abstinence, while external motivators were reported to be more influential in early stages. Findings indicate that motivation for substance abstinence is a multidimensional and dynamic construct shaped by personal and contextual factors. Fostering intrinsic motivation, establishing supportive structures, and addressing motivational barriers are essential for effective intervention design and addiction recovery policy-making.
