Quality of life and its relationship with perceived stigma among opioid use disorder patients: An exploratory study

Abstract

Background: In view of recent global opioid epidemic and scarcity of literature assessing the quality of life (QoL) and stigma among opioid use disorder (OUD) patients, this study aimed to assess the overall QoL and examine its relationship with perceived stigma among them. Materials and Methods: This cross-sectional study assessed patients with OUD at a tertiary care centre. QoL was assessed using the World Health Organization Quality of Life-brief version, whereas perceived stigma was measured using the Perceived Stigma of Substance Abuse Scale (PSAS). Results: Among 168 patients with OUD, all the four domain-wise scores of physical health (r = 0.79, P < 0.01), psychological health (r = 0.87, P < 0.01), social relationships (r = 0.78, P < 0.01) and environment (r = 0.80, P < 0.01) QoL correlated significantly with average score, with maximum impairment noted in the social domain. The mean PSAS score was 21.19 ± 2.99, with perceived stigma found to be significantly associated with impairments in the physical (β = -0.28, P < 0.01), psychological (β = -0.27, P < 0.01) and environment (β = -0.21, P < 0.01) domains of QoL. Furthermore, being employed was significantly associated with impairment in the social domain of QoL (β = -0.17, P = 0.02). Conclusion: OUD similarly affects all the four domains of QoL, with a higher level of perceived stigma associated with significantly poorer QoL in the physical, psychological and environment domains. However, future studies assessing different forms of stigma and QoL among patients with OUD are needed to confirm and better characterise the findings of this study.
