Trauma History |
The Life Events Checklist for DSM-5 includes 17 self-report items that assess a number of different types of traumatic events across the lifespan and personal occurrence versus learning about a traumatic event (Weathers et al., 2013). There is no formal scoring protocol, although endorsing 1 or more items indicates lifetime exposure to a traumatic event. |

Comorbid Mental Health Conditions |
Current substance use disorders, major depressive disorder, and generalized anxiety disorder diagnoses will be assessed with the respective modules from the Structured Clinical Interview for DSM-5 (First, 2014). Each module includes structured interview questions in "yes/no" response format, with a scoring protocol that indicates whether the participant met criteria for the DSM-5 psychological disorder diagnosis. A categorical outcome will be used (scored "0" for did not meet criteria for the diagnosis, "1" for met criteria for the diagnosis). |

Intervention Adherence/Mindfulness Practice Frequency |
Additional mindfulness practices engaged in outside of the study sessions assessed with four self-report items: 'Did you engage in mindfulness meditation in the past month?' (yes = 1, no = 0), 'How many days per week did you engage in mindfulness meditation?' (range = 0-7), 'How long in minutes did you meditate per session of mindfulness meditation?' (range = 0 to unspecified), 'Describe your practice of mindfulness meditation (what exercises/activities/techniques did you practice?). Each quantitative item will be analyzed separately as moderators of intervention outcome and reported descriptively. |
Assessed at 8 weeks (post-intervention for experimental group), and 16 weeks (follow-up for experimental group, post-intervention for control group) |

Change in frequency of opioid/alcohol use |
Frequency and time to first use will be assessed with both self-timeline follow-back method and collateral timeline follow-back for the past 60 days (Wray et al 2016; Donohue et al., 2004), as well as urine samples. |
Baseline, 8 weeks (post-intervention for experimental group), 16 weeks (follow-up for experimental group, post-intervention for control group) |

Change in opioid/alcohol craving |
We will assess craving with the Penn Alcohol Craving Scale, which will be modified to assess opioid craving for individuals with opioid use disorder (Garland et al., 2014; Flannery, Volpicelli, & Pettinati, 1999). The Penn Scale is a 5 item self-report measure with scores ranging from 0 to 30, with higher scores indicating higher levels of craving. |

Change in withdrawal symptoms |
Assessed with The Short Opiate Withdrawal Scale (Gossop, 1990) and the Short Alcohol Withdrawal Scale (Gossop et al., 2002). The Short Opiate Withdrawal Scale and the Short Alcohol Withdrawal Scale are each10 item self-report scales, with scores ranging from 0 to 30, with higher scores indicating more withdrawal symptoms. |

Change in quality of life: World Health Organization Quality of Life (WHOQOL)-BREF |
Quality of life will be assessed with the World Health Organization Quality of Life (WHOQOL)-BREF. The WHOQOL-BREF is a 26 item self-report measure that assesses four domains: physical health, psychological, social relationships, and environment. Transformed scores range from 0 to 100 for each of the four domains, with higher scores indicating greater quality of life. |

Change in perceived stress |
Perceived stress will be assessed with the Short Form Perceived Stress Scale (PSS-4) (Warttig et al 2013). This scale is 14 items and asks the frequency of feeling stressed on a 0 to 4 scale (total score range of 0-56), with higher scores indicating lower perceived stress. |

Change in posttraumatic stress symptoms |
The PTSD Checklist for DSM-5 (PCL-5) will be used to assess PTSD symptoms (Weathers et al, 2013). This scale includes 20 items on a five point scale to assess for PTSD symptom severity. The total score ranges from 0 to 80 with higher scores indicate more severe symptoms. |

Change in pain severity: Brief Pain Inventory |
Pain severity will be assessed with the pain severity subscale of the Brief Pain Inventory (Cleeland & Ryan, 1994). The subscale consists of four self-report items (rated 0 to 10), with a total score ranging from 0 to 40. Higher scores indicate higher pain severity. |

Change in medication adherence |

Change in mindfulness skills |
The Five Facet Mindfulness Questionnaire (Baer et al, 2006) includes 39 self-report items assessing five dimensions of mindfulness. Items are rated on a 5 point scale ranging from 1 to 5, with total score ranging from 39 to 195. Higher scores indicate greater dispositional tendency to be mindful in daily life (e.g., observing, describing, acting with awareness, nonjudging of inner experience, nonreactivity to inner experiences). |

Change in emotion regulation skills |
The Difficulties in Emotion Regulation Scale-Short Form (Kaufman et al., 2016) includes 18 items that assess four areas of emotion regulation: awareness/understanding, acceptance, ability to engage in goal-directed behavior, ability to control impulsive behavior. The items are rated on a 1 (almost never) to 5 (almost always) scale based on frequency of feelings and use of emotion regulation skills, with a total score range of 18-90. Higher scores reflect greater impairments in emotion regulation skills. |

Total scores can range from -72 to +72, with higher scores indicating higher levels of savoring. |

Change in positive and negative affect |
The Positive and Negative Affect scales assess dispositional dimensions of affect (Watson, Clark, & Tellegen, 1998). Two separate subscales will be used. There are 10 items to evaluate positive affect and 10 items to evaluate negative affect with a range of 10-50 for each scale. Each item is rated according to frequency of feeling a certain way, with higher scores on each scale indicating higher positive or negative affect. |
