The aims of this study were to establish the prevalence of psychotropic drug use, measure the association between job strain, extrinsic efforts-rewards ratio, interpersonal violence and psychotropic drug use among officers working in correctional facilities in the province of Quebec in Canada. This study also examined if interpersonal violence at work is an intermediate factor in the causal chain between psychosocial risk factors at work and psychotropic drug use. A cross-sectional study was performed which included 1288 Quebec correctional officers. The participants answered a self-administered questionnaire in 2007 assessing psychological demands, decision latitude, extrinsic efforts, rewards, overcommitment, intimidation, psychological harassment, social support in the actual job, psychotropic drug use during the month preceding the questionnaire and sociodemographic variables. Binomial regressions were performed for the principal associations and a bootstrap analysis was performed in order to evaluate interpersonal violence as an intermediate factor between psychosocial risk factors at work and psychotropic drug use. The prevalence of psychotropic drug use among correctional officers was 14.7%. The prevalence ratios (PR) for the associations between job strain, extrinsic efforts-rewards ratio, social support from colleagues and supervisors, intimidation and psychological harassment adjusted for age and gender were respectively 1.4 (95% CI 0.9-2.2), 1.6 (95% CI 1.2-2.2), 1.7 (95% CI 1.3-2.3), 1.4 (95% CI 0.9-2.4) and 1.5 (95% CI 1.1-2.0). The value of the indirect effect evaluating psychological harassment as an intermediate factor was not statistically significant (value=0.0087, 95% CI -0.0033 to 0.0207). An imbalanced extrinsic efforts-rewards ratio, low social support from colleagues and supervisors and psychological harassment at work were separately associated with psychotropic drug use among correctional officers. Psychological harassment was not found to be an intermediate factor.
本研究旨在确定精神活性药物使用的流行率，衡量魁北克省惩教设施中工作人员的工作压力、外在努力-回报比、人际暴力与精神活性药物使用之间的关系。本研究还检验了工作场所人际暴力是否是工作场所心理社会风险因素与精神活性药物使用之间因果关系链中的中间因素。这是一项横断面研究，共纳入了 1288 名魁北克惩教官员。参与者于 2007 年通过自填问卷评估了心理需求、决策自由度、外在努力、回报、过度投入、恐吓、心理骚扰、实际工作中的社会支持、问卷前一个月的精神活性药物使用情况以及社会人口统计学变量。对主要关联进行了二项回归分析，并进行了自举分析，以评估人际暴力作为工作场所心理社会风险因素与精神活性药物使用之间的中间因素。惩教官员精神活性药物使用的流行率为 14.7%。在校正年龄和性别后，工作压力、外在努力-回报比、同事和主管的社会支持、恐吓和心理骚扰与精神活性药物使用之间的关联的比值比（PR）分别为 1.4（95%CI 0.9-2.2）、1.6（95%CI 1.2-2.2）、1.7（95%CI 1.3-2.3）、1.4（95%CI 0.9-2.4）和 1.5（95%CI 1.1-2.0）。评估心理骚扰作为中间因素的间接效应值无统计学意义（值=0.0087，95%CI -0.0033 至 0.0207）。工作中外在努力-回报比不平衡、同事和主管的社会支持低以及工作中的心理骚扰分别与惩教官员的精神活性药物使用有关。未发现心理骚扰是中间因素。
