Abstract

Illness perception and treatment motivation are increasingly recognised as important psychological components influencing treatment outcomes. A lack of study has been identified in the addiction field, either locally or globally. This study aims for the novel views and to examine the relationships between sociodemographic factors, Illness Perception, Treatment Motivation, and Quality of Life. Methods: A cross-sectional study was conducted among 149 patients undergoing treatment for Substance Use Disorder (SUD). Validated tools were used, including the Brief Illness Perception Questionnaire (BIPQ), Treatment Motivation Scale (TMS), and EuroQoL. Descriptive statistics and univariate statistical analyses assessed the relationships between variables. Results:Illness perception is positively correlated with QoL in general and particularly in domains of consequences, timeline, identity, and emotional representation. Treatment motivation does not significantly differentiate between high and low QoL groups. Substance use duration influenced illness perception, while gender and religion shaped treatment motivation. No sociodemographic factor directly predicted QoL. Conclusion: The findings underscore the importance of considering illness perception and sociodemographic factors when designing targeted interventions. Although treatment motivation was not directly linked to QoL, it remains an essential element in personalised care. Future research should explore more the relevancy of illness perception in treating substance-using populations.
