Detaillierte Beschreibung
Distress intolerant cannabis users were randomized to a computerized distress intolerance intervention or a control intervention.
Primary and secondary outcomes consist of the treatment target, cannabis use-related behavior, and theoretically-relevant neurophysiological processes (i.e., cannabis cue reactivity, response inhibition).

Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Change in Distress Intolerance Index (DII) score from Baseline through 4-Month Follow-Up
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Self-report measure of Distress Intolerance (Distress Intolerance Index [DII]; McHugh & Otto, 2012).
The DII is a self-report measure comprised of 10 items that are summed together to form a total score (minimum: 0; maximum: 40).
Higher scores indicate greater distress intolerance (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Change in Mirror-Tracing Persistence Task (MTPT) quit latency from Baseline to Post-Treatment
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Behavioral measure of Distress Intolerance (Mirror-Tracing Persistence Task [MTPT]; Macatee & Cougle, 2015).
The MTPT is a behavioral persistence measure that assesses behavioral distress intolerance via the latency to quit a distressing task.
Scores range from 0 seconds to a maximum persistence time of 7 minutes.
Lower scores indicate greater distress intolerance (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Change in Marijuana Problems Scale (MPS) score from Baseline through 4-Month Follow-Up
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Self-report measure of marijuana use-related problems (Marijuana Problems Scale [MPS]; Stephens et al., 2000).
The MPS is a self-report measure of marijuana use-related problem severity in the past month.
The measure is comprised of 19 items with a minimum score of 0 and a maximum score of 38.
Higher scores indicate greater marijuana use-related problem severity in the past month (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Change in Cannabis Use Disorder (CUD) diagnostic criteria from Baseline to 4-Month Follow-Up
Zeitfenster: Baseline, 4-month follow-up
|
Interviewer-assessed Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 Cannabis Use Disorder diagnostic criteria.
DSM-5 Cannabis Use Disorder criteria were assessed via interview at baseline and again at the 4-month follow-up.
Total number of Cannabis Use Disorder criteria was used to assess Cannabis Use Disorder severity (minimum score: 0; maximum score: 11).
Higher scores indicate greater Cannabis Use Disorder severity (i.e., worse outcome).
|
Baseline, 4-month follow-up
|
Change in Timeline follow-back (TLFB) cannabis use frequency from Baseline through 4-Month Follow-Up
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Percent cannabis use days in the past month (Timeline follow-back [TLFB]; Hjorthoj et al., 2012).
The Timeline follow-back (TLFB) is a self-report measure that assesses cannabis use over the past 4 weeks.
Percentage of days on which cannabis was used in the past four weeks was used to assess cannabis use frequency (minimum: 0%; maximum: 100%).
Higher scores indicate greater cannabis use frequency (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Change in Marijuana Motives Measure (MMM) score from Baseline through 4-Month Follow-Up
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Self-reported motives for cannabis use (Marijuana Motives Measure [MMM]; Zvolensky et al., 2007).
The Marijuana Motives Measure (MMM) is a self-report measure that assesses different motives for marijuana use.
The coping motives subscale was the subscale of interest in this project.
The Coping motives subscale is comprised of 4 items that are then averaged (minimum score: 1; maximum score: 5).
Greater scores indicate greater coping motives for marijuana use (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session), 1-month follow-up, 4-month follow-up
|
Change in Marijuana Craving Questionnaire (MCQ) score from Baseline to Post-Treatment
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Self-reported state craving for marijuana (Marijuana Craving Questionnaire [MCQ]; Heishman et al., 2009).
The Marijuana Craving Questionnaire (MCQ) is a self-report measure of current craving for marijuana use.
The emotionality subscale was the subscale of interest in this project.
The Emotionality subscale is comprised of 5 items that are then averaged (minimum score: 1; maximum score: 7).
Greater scores indicate greater marijuana craving (i.e., worse outcome).
In this project, the outcome of interest is the extent to which a laboratory stress induction increases state marijuana craving.

Zeitfenster |
---|---|---|
Change in electroencephalography (EEG) index of acute stress modulation of cannabis cue reactivity (assessed by the Late Positive Potential [LPP]) from Baseline to Post-Treatment
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Acute Stress modulation of the Late Positive Potential (LPP) to Cannabis Cues.
The LPP to visual cannabis cues before and after a laboratory stress induction will be measured as a neurophysiological index of acute stress modulation of cannabis cue incentive salience.
Greater values indicate a larger neural response to cannabis cues during acute stress (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Change in electroencephalography (EEG) index of acute stress modulation of threat reactivity (assessed by the Late Positive Potential [LPP]) from Baseline to Post-Treatment
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Acute Stress modulation of the Late Positive Potential (LPP) to threat stimuli.
The LPP to visual threat stimuli before and after a laboratory stress induction will be measured as a neurophysiological index of acute stress modulation of threat reactivity.
Greater values indicate a larger neural response to threat during acute stress (i.e., worse outcome).
|
Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Change in electroencephalography (EEG) index of acute stress modulation of response inhibition (assessed by the N200 [N2]) from Baseline to Post-Treatment
Zeitfenster: Baseline, post-treatment (i.e., ~1 week following the last treatment session)
|
Acute stress modulation of the N2 to no-go stimuli.
The N2 to no-go vs. go stimuli on a go/no-go task before and after a laboratory stress induction will be measured as a neurophysiological index of the acute stress modulation of response inhibition.
More negative values indicate a larger neural response to stimuli requiring response inhibition during acute stress (i.e., better outcome).
