Study summary

The purpose of this research study is to look at the effect of programs aimed at helping people manage chronic pain and medication treatment. The program sessions focus on educational information and strategies for pain and medication management. The researchers enroll people who have chronic pain and have recently begun buprenorphine treatment to see if participants could benefit from these programs. This research study will help the researchers learn how to improve current therapies for pain and medication management.

    Eight Cognitive Behavioral Therapy-based individual telephone or video therapy sessions with research study therapist.

  • Active comparator
    Enhanced Usual Care (EUC)

    Two individual telephone educational sessions with research study therapist.

Interventions

  • BehavioralPsychosocial Pain Management (PPMI)

    The main theme of the treatment is to provide participants with new ways of thinking and coping skills related to managing pain and opioid use in order to increase the likelihood the participant may remain in buprenorphine treatment.

  • BehavioralEnhanced Usual Care (EUC)

    The EUC condition is designed to match the PPMI condition in terms of the non-specific aspects of receiving support for pain, substance use, and receiving monitoring of buprenorphine adherence.

What researchers measure

Primary outcomes

  1. Retention on Buprenorphine Treatment According to TimeLine Follow-Back - 3-months

    In this study, "retention on buprenorphine treatment" was defined as the time until a participant stopped taking their medication for 7 or more days in a row. This information was collected using a calendar recall method, the TimeLine Follow-Back (TLFB) measure at 3 months. The average number of days participants remained on buprenorphine before this happened was calculated, using the data collected at 3-month follow-up.

    Time frame: 3-months post enrollment

Secondary outcomes

  1. Retention on Buprenorphine Treatment According to TimeLine Follow-Back - 12 Months

    In this study, "retention on buprenorphine treatment" was defined as the time until a participant stopped taking their medication for 7 or more days in a row. This information was collected using a calendar recall method, the TimeLine Follow-Back (TLFB) measure at 12 months. The average number of days participants remained on buprenorphine before this happened was calculated, using the data collected at 12-month follow-up.

    Time frame: 12-months post enrollment

  2. Average Change in Self-reported Level of Pain Intensity on the Numerical Rating Scale for Pain Intensity (NRS-I) at 3-month Follow up (Compared to Baseline)

    Pain level will be measured using the Numerical Rating Scale for Pain Intensity (NRS-I), an 11-point numeric rating scale (0=no pain, 10= worst pain imaginable), which will be collected at the baseline enrollment assessment and 3-month follow-up. To calculate our measure, we subtracted each participant's score at 3-month assessment and subtracted it from their baseline score. We then averaged calculated average change in scores for each intervention group.

    Time frame: 3-months post enrollment

  3. Average Change in Self-Reported Level of Pain Related Functioning on the Brief Pain Inventory - Short Form (BPI) at 3-month Follow up (Compared to Baseline)

    Pain-related functioning will be measured using the pain interference subscale of the Brief Pain Inventory - Short Form (BPI), an 11-point numeric rating scale (0 = no pain/does not interfere, 10 = worst pain imaginable/completely interferes). For this study, an increase in pain-related functioning will be measured as a reduction in the pain interference scale scores over time. The BPI interference subscale measures how much pain has interfered with seven daily activities and will provide a current level of pain-related functioning (past 24-hours) at the 3-month follow-up. BPI pain interference will be calculated as the mean of the seven interference items. For each follow-up time point, the baseline value will be subtracted to obtain a change score.

    Time frame: 3-months post enrollment

  4. Percent Days Abstinent From Substance Use on the TimeLine Follow-Back - 3-months

    Frequency of substance use will be measured using the TimeLine Follow-Back and will be collected at 3-month follow-up. During the administration, the participant will be asked to recall their alcohol and drug use utilizing a calendar-assisted structured interview that provides the participant with temporal cues to increase the accuracy of recall. At each follow-up, data will be collected for the entire period since the previous date of data collection. Percent days abstinent from substances (e.g. alcohol and drugs) will be used as the primary measure of substance use. Values shown are the treatment group average percent of days that participants were abstinent from substances after 3 months follow-up.

    Time frame: 3-months post enrollment

  5. Average Change in Self-reported Level of Pain Intensity on the Numerical Rating Scale for Pain Intensity (NRS-I) at 12-month Follow up (Compared to Baseline)

    Pain level will be measured using the Numerical Rating Scale for Pain Intensity (NRS-I), an 11-point numeric rating scale (0 = no pain, 10 = worst pain imaginable), which will be collected at the baseline enrollment assessment and the 12-month follow-up. For each follow-up time point, the baseline value will be subtracted to obtain a change score.

    Time frame: 12-months post enrollment

  6. Average Change in Self-Reported Level of Pain Related Functioning on the Brief Pain Inventory - Short Form (BPI) at 12-month Follow up (Compared to Baseline)

    Pain-related functioning will be measured using the pain interference subscale of the Brief Pain Inventory - Short Form (BPI), an 11-point numeric rating scale (0 = no pain/does not interfere, 10 = worst pain imaginable/completely interferes). For this study, an increase in pain-related functioning will be measured as a reduction in the pain interference scale scores over time. The BPI interference subscale measures how much pain has interfered with seven daily activities and will provide a current level of pain-related functioning (past 24-hours) at the 12-month follow-up. BPI pain interference will be calculated as the mean of the seven interference items. For each follow-up time point, the baseline value will be subtracted to obtain a change score.

    Time frame: 12-months post enrollment

  7. Percent Days Abstinent From Substance Use on the TimeLine Follow-Back - 12 Months

    Frequency of substance use will be measured using the TimeLine Follow-Back and will be collected at the 12-month follow-up. During the administration, the participant will be asked to recall their alcohol and drug use utilizing a calendar-assisted structured interview that provides the participant with temporal cues to increase the accuracy of recall. At each follow-up, data will be collected for the entire period since the previous date of data collection.
