Abstract

To evaluate the impact of a new Substance Use Disorder (SUD) education program on medical students’ attitudes, we selected the Substance Abuse Attitude Survey (SAAS) questionnaire, which we adapted to our curriculum and cultural context. To validate this adapted version, we conducted an exploratory factor analysis following the administration of our 29-item bSAAS questionnaire to 657 medical students in Belgium (response rate: 71.1%). Twenty-three items correlated to three factors; namely, “Stereotypes and moralism”, “Treatment optimism” and “Specialized treatment” were retained (70% of total variance explained, Cronbach’s alpha = 0.80) and constituted the new questionnaire called beSAAS. The factor “Specialized treatment” stood out from previous studies, which could be explained by our target population and the impact of the formal, informal and hidden curricula in medical education. This study was able to highlight certain factors influencing stereotypical representations such as age, gender, origin, personal or professional experience with substance use. Our study allowed us to retain the beSAAS as a good questionnaire to evaluate SUD stigma and highlighted interesting findings to improve SUD training in medicine. Further studies are needed to complete its validity and reliability.

Stigma among health professionals towards patients with substance use disorders and its consequences for healthcare delivery: systematic review.

Leonieke C van Boekel, Evelien Brouwers, Jaap van Weeghel … (2013)

Healthcare professionals are crucial in the identification and accessibility to treatment for people with substance use disorders. Our objective was to assess health professionals' attitudes towards patients with substance use disorders and examine the consequences of these attitudes on healthcare delivery for these patients in Western countries. Pubmed, PsycINFO and Embase were systematically searched for articles published between 2000 and 2011. Studies evaluating health professionals' attitudes towards patients with substance use disorders and consequences of negative attitudes were included. An inclusion criterion was that studies addressed alcohol or illicit drug abuse. Reviews, commentaries and letters were excluded, as were studies originating from non-Western countries. The search process yielded 1562 citations. After selection and quality assessment, 28 studies were included. Health professionals generally had a negative attitude towards patients with substance use disorders. They perceived violence, manipulation, and poor motivation as impeding factors in the healthcare delivery for these patients. Health professionals also lacked adequate education, training and support structures in working with this patient group. Negative attitudes of health professionals diminished patients' feelings of empowerment and subsequent treatment outcomes. Health professionals are less involved and have a more task-oriented approach in the delivery of healthcare, resulting in less personal engagement and diminished empathy. This review indicates that negative attitudes of health professionals towards patients with substance use disorders are common and contribute to suboptimal health care for these patients. However, few studies have evaluated the consequences of health professionals' negative attitudes towards patients with substance use disorders. Copyright © 2013 Elsevier Ireland Ltd.

Exploratory factor analysis: its role in item analysis.

R Gorsuch (1997)

The special characteristics of items-low reliability, confounds by minor, unwanted covariance, and the likelihood of a general factor-and better understanding of factor analysis means that the default procedure of many statistical packages (Little Jiffy) is no longer adequate for exploratory item factor analysis. It produces too many factors and precludes a general factor even when that means the factors extracted are nonreplicable. More appropriate procedures that reduce these problems are presented, along with how to select the sample, sample size required, and how to select items for scales. Proposed scales can be evaluated by their correlations with the factors; a new procedure for doing so eliminates the biased values produced by correlating them with either total or factor scores. The role of exploratory factor analysis relative to cluster analysis and confirmatory factor analysis is noted.

The effectiveness of interventions for reducing stigma related to substance use disorders: a systematic review

James D Livingston, Teresa Milne, Mei Lan Fang … (2012)

Aims This study provides a systematic review of existing research that has empirically evaluated interventions designed to reduce stigma related to substance use disorders. Methods A comprehensive review of electronic databases was conducted to identify evaluations of substance use disorder related stigma interventions. Studies that met inclusion criteria were synthesized and assessed using systematic review methods. Results Thirteen studies met the inclusion criteria. The methodological quality of the studies was moderately strong. Interventions of three studies (23%) focused on people with substance use disorders (self-stigma), three studies (23%) targeted the general public (social stigma) and seven studies (54%) focused on medical students and other professional groups (structural stigma). Nine interventions (69%) used approaches that included education and/or direct contact with people who have substance use disorders. All but one study indicated their interventions produced positive effects on at least one stigma outcome measure. None of the interventions have been evaluated across different settings or populations. Conclusions A range of interventions demonstrate promise for achieving meaningful improvements in stigma related to substance use disorders. The limited evidence indicates that self-stigma can be reduced through therapeutic interventions such as group-based acceptance and commitment therapy. Effective strategies for addressing social stigma include motivational interviewing and communicating positive stories of people with substance use disorders. For changing stigma at a structural level, contact-based training and education programs targeting medical students and professionals (e.g. police, counsellors) are effective.
