Assessed using the Patient Health Questionnaire-9 (PHQ-9) The PHQ-9 is an 9-item questionnaire where participants report how often in the past 2 weeks they were bothered by specific problems. It is scored on a 4-point Likert scale where 0 = not at all to 3 = nearly every day. The total possible range of scores is 0-27 where higher scores indicate more depressive symptoms.

Assessed with 16 items from the Dialectical Behavior Therapy (DBT) skills subscale of the Ways of Coping Checklist, a 38 item self-report instrument that assesses DBT skills utilization in the past week on a scale from 0 = never used to 3 = used regularly. The checklist has excellent psychometric properties and has been shown to discriminate patients who received skills training during treatment from those who did not. Scores range from 0-48, where higher scores reflect greater skills utilization.

Assessed with the 8-item Perceived Present Control subscale of the Perceived Control Over Stressful Events Scale. Statements are rated on a Likert scale ranging from 1 (Very strongly disagree) to 4 (Very strongly agree), with a score range of 8-32, where higher averages indicate stronger perceived control. The scale has excellent psychometric properties and higher scores (which reflect greater perceived control) have been associated with recovery following sexual violence.

Assessed with the Brief Pain Inventory (BPI), a 4-item self-report measure that asks participants to rate their worst pain in the last week, their least pain in the last week, their pain on average, and their pain right now on a scale from 0 = no pain at all to 10 = pain as bad as you can imagine. An overall pain severity score is computed by taking the mean of the four items.

Assessed with the 3-item Opioid Craving Scale which asks participants to rate how strong their desire to use opioids in the past 24-hours was (0 = no desire to use, 9 = extremely strong desire to use), how likely they would be to use if in the same environment when they used to use (0 = not at all likely, 9 = extremely likely), and how strong urges for opioids are when something reminds survivor of opioids (0 = no urge to use, 9 = extreme urge to use). Items are averaged for a total score (ranging from 0-9). Only those with any opioid use experience are asked these questions.

Assessed via the Difficulties in Emotion Regulation Scale - 16 item version (DERS-16), which asks about the frequency with which individuals experience difficulties in emotion regulation from 1 = not at all to 5 = almost always. Items are summed so total scores range from 16-80, with higher scores indicating greater difficulties in emotion regulation.

Assessed using the The Multidimensional Scale of Perceived Social Support (MSPSS). MSPSS is a 12-item tool measuring support from family, friends, and significant others using a 7-point Likert scale (1=Very Strongly Disagree to 7=Very Strongly Agree). Total scores range from 12 to 84, with higher scores indicating greater perceived support.

Assessed via 6 items from the Self Compassion Scale-Short Form (SCS-SF) that assess self-kindness, common humanity, and mindfulness on a scale from 1 = almost never to 5 = almost always. Items are averaged so total scores range from 1-5 where higher scores show higher self compassion.
