SMART Trial: Intrapersonal and Interpersonal Stigma Reduction

Enacted Stigma (Intrapersonal)

Change in Enacted Stigma subscore from Substance Use Stigma Mechanisms Scale (SU-SMS) pre- and post-intervention. All responses are given on a 5-point Likert-type scale, with higher scores indicating greater endorsement of substance use stigma. Enacted (6 items) scale can be created by taking the average of the item responses given. Minimum score = 6, Maximum score = 30. Reported mean is the change in these scores (pre score - post score), so a positive number for the mean is a reduction in stigma using average scores from the Enacted Stigma subscore.

Time frame: Immediately before and 2-weeks post-intervention delivery

Anticipated Stigma (Intrapersonal)

Change in Anticipated Stigma subscore from Substance Use Stigma Mechanisms Scale (SU-SMS) pre- and post-intervention. All responses are given on a 5-point Likert-type scale, with higher scores indicating greater endorsement of substance use stigma. Enacted (6 items) scale can be created by taking the average of the item responses given. Minimum score = 6, Maximum score = 30. Reported mean is the change in these scores (pre score - post score), so a positive number for the mean is a reduction in stigma using average scores from the Anticipated Stigma subscore.

Time frame: Immediately before and 2-weeks post-intervention delivery

Internalized Stigma (Intrapersonal)

Change in Internalized Stigma subscore from Substance Use Stigma Mechanisms Scale (SU-SMS) pre- and post-intervention. All responses are given on a 5-point Likert-type scale, with higher scores indicating greater endorsement of substance use stigma. Enacted (6 items) scale can be created by taking the average of the item responses given. Minimum score = 6, Maximum score = 30. Reported mean is the change in these scores (pre score - post score), so a positive number for the mean is a reduction in stigma using average scores from the Internalized Stigma subscore.

Time frame: Immediately before and 2-weeks post-intervention delivery

Exposure to Drug Users Index Score

Exposure to drug users index includes questions regarding if a participant has been exposed to a drug user at home, at work, at school, etc. (7 items; No = 0, Yes = 1). Score is total count (min score = 0, max score = 7). Higher scores indicate more exposure to drug users. Reported mean is the change in this score pre and post intervention (post score - pre score).

Time frame: Pre/post intervention (week 0)

Drug Use Stigmatization Scale Score

The Drug Use Stigmatization Scale measures stigma against drug users. The scale contains 7 items scored on a 5-point likert scale with higher scores representing higher stigma. The score is the average score of the seven items. Min score = 1, Max score = 5. Reported mean is the change in these scores (pre score - post score), so a positive number for the mean is a reduction in stigma.

Time frame: Pre/post intervention (week 0: post-test immediately followed intervention)

Stigma of Drug Users Scale Score

The Stigma of Drug Users Scale measures stigma. There are 10 items scored on a 5-point likert scale. Higher scores indicate higher stigma. The score is the average of the 10 items (Min score = 1, Max score = 5). The reported mean for this outcome measure is the change in this score pre and post intervention (pre score - post score). A positive mean indicates a reduction in stigma.

Time frame: Pre/post intervention (week 0: post-test immediately followed intervention)
