NCT03373240

Brief Summary

We are proposing a small randomized clinical trial in which 100 substance users will complete the existing Psychotherapy Development Center (PDC) pretreatment assessment battery as well as a novel battery of assays to evaluate cognitive-affective functioning. After completing pretreatment assessments, participants will be randomized to either a (1) cognitive remediation program (training tasks) specifically designed to address cognitive-affective dysregulation or (2) control tasks (verbal fluency tasks). Tasks will be completed twice per week for 4 weeks, after which assessment batteries will be repeated. Finally, we will evaluate real-world behavior and the durability of the training via a one-month follow-up, which will include assessment of substance use as well as the cognitive-affective battery.

Outcome Measures

Primary Outcomes (10)

  • Change in Stop Signal Reaction Time

    Improved functioning on cognitive-affective battery: Examining Stop Signal reaction time changed across the 4-week training period. A change score was calculated. A negative number indicates better inhibition over time.

    Training visit 1 through 4 weeks of training

  • Change From Pre-Post in Substance Use

    The cube root of the number of days the participant endorsed using their primary substance. The number of days was submitted to a cube root transformation given skewness and a change score was calculated (post minus pre). A negative number indicated decreased substance use over time.

    4 weeks before First Training Session through the 4-week training period

  • Change in Pre-Post Cognitive Affective Battery- Negative Urgency Subscale (Part of the Urgency, Premeditation (Lack of), Perseverance (Lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale)

    Negative urgency (NU) subscale. The scale score range is 11-44. Higher values indicate stronger agreement with this pathway toward impulsivity. A change score was calculated. A negative number indicates less agreement with negative urgency.

    from the week prior to training to the week after training

  • Change in Experimental Performance-Change in Percentage of Risky Choices Under Risk Condition of the Lottery Task

    The percent of risky choices per session. This would indicate that the participant selected the lottery option that reflected a riskier bet. A change score was calculated. A negative number indicates improved decision-making (selecting fewer risky options).

    Training visit 1 through 4 weeks of training

  • Change in Experimental Performance- Change in Percentage of Ambiguous Choices Under 24% Ambiguity in Lottery Task

    Percent of choices the participant made that reflected selecting the ambiguous option. A change score was calculated. A negative number reflects improved decision-making (selecting more safe options).

    Training visit 1 through 4 weeks of training

  • Change in Experimental Performance- Paced Auditory Serial Addition Test (PASAT)

    Estimated change in percentage of trial attempts on round 3 of the PASAT. A positive number reflects more trial attempts in the third round of PASAT.

    from the week prior to training (pre) to the week after training (post)

  • Change in Pre-Post Cognitive Affective Battery: Digit Backwards

    Score on digit backwards. Fourteen strings of varying lengths (2 to 7 digits) are presented. A participant receives a point for each string they correctly repeat backwards. Range 0-14 points. Change score was calculated-positive values indicate improved working memory over time.

    from the week prior to training (pre) to the week after training (post)

  • Change in Pre-Post Cognitive Affective Battery: Breath Holding

    Negative emotionality-distress tolerance as measured by the difference between when the participant says they are uncomfortable and when they let go of holding their breath. Measured in seconds (this was natural log-transformed due to skewness for analyses). Positive change indicates improved distress tolerance over time.

    from the week prior to training (pre) to the week after training (post)

  • Change in Pre-Post Cognitive Affective Battery: Perceived Stress Scale

    Negative emotionality-perceived stress. The total score ranges from 0-4. Higher scores indicate a higher level of perceived stress. A change score was calculated. Negative change indicates an improvement (reduction in perceived stress) over time.

    from the week prior to training (pre) to the week after training (post)

  • Change in Pre-Post Cognitive Affective Battery: Delay Discounting

    Incentive salience- delay discounting. Five-Trial Adjusting-Delay Discounting Task (Koffarnus \& Bickel, 2014) is a 5-item behavioral assessment used to estimate the extent to which individuals prefer smaller immediate rewards over larger delayed rewards. A discount rate (ln (k)) is calculated for each time the measure is used. Discount rates for the 5- trial delay task were calculated by taking the inverse of the obtained Effective Delay 50 value, which is equivalent to the value of k, when fitted to this singular point. Ln(k) is the natural log of the discount rate. A change score was calculated. Negative change indicates improved decision-making

    from the week prior to training (pre) to the week after training (post)
