The usefulness of primary care physician-led motivational interview in a substance abuse check-up clinic: a retrospective study

Abstract

Objective: To assess the outcome of a structured health check-up clinic for substance abusers. Design: Retrospective study on 73 participants who attended a health check-up clinic led by primary care physicians using motivational interviewing. Participants were assessed by a self-report questionnaire, before and 3-12 months after motivational interviews. Subjects: Attendees aged 13-36 years with history of psychoactive drug abuse. Main outcome measures: One month and three months psychoactive drug abstinence rate, pattern of drug use and subjective usefulness of clinic visits. Results: 87.7% (64 out of 73) participants completed both pre- and post- interview questionnaires. The post-intervention 3-months abstinence rate was significantly higher (59.4 %) when compared to pre-intervention (9.6%; p<0.001). The total drug score and number of drugs used reduced significantly both in the past 1 month and 3 months. 93.2% found the service helpful, and 86.2% found that motivational interview could increase their confidence of abstinence. Conclusion: A structured programme consisting of substance abuse health check-up clinic with motivational interviewing by primary care physician is effective for abstinence and reduction in drug-use.

目的：對一家為藥物濫用者而設之結構化體檢診所結果進行評估。 設計：採用動機性訪談，對73名到由基層醫生主導的體檢診所就診的參加者進行回顧性研究。在動機性訪談前以及之後3-12個月，通過自我報告問卷，對參加者進行評估。 對象：有精神藥物濫用史的13-36歲就醫者。 主要測量內容：一個月和三個月精神藥物戒斷率，藥物濫用模式，到診所就醫是否有用的主觀感受。 結果：87.7%（64/73）的參加者完成了訪談前問卷和訪談後問卷。干預後三個月的戒斷率（59.4 %）明顯高於干預前（9.6%；p<0.001）。過去一個和三個月的藥物總分和用藥數量均顯著減少。93.2%的人認為提供的服務有用，86.2%的人認為動機性訪談可增加他們對戒斷的信心。 結論：由藥物濫用體檢診所和基層醫生開展動機性訪談所構成的結構化專案，能有效戒斷和減少藥物濫用。
