Following the COVID-19 pandemic, it is vital to understand how major global stressors influence substance use, including cannabis-related outcomes. The Marijuana Purchase Task assesses hypothetical cannabis demand (i.e., relative reinforcing value) and can detect contextual alterations. This study paired prospective assessment with qualitative inquiry explore impacted use behavior. Individuals previously enrolled in a laboratory administration opted remote follow-up survey (n = 41, 46% female). Participants were categorized as those who did or not increase based on self-reported changes flower provided explanations regarding pandemic-related influences General linear models repeated measures examined mean differences by occasion before/during COVID-19), group did/did use), their interaction.

Abstract Background and aims The Marijuana Purchase Task (MPT) is increasingly used to measure cannabis reinforcing value has potential use for etiological regulatory research. This meta‐analysis sought evaluate the first time MPT's concurrent validity in relation involvement. Methods Electronic databases pre‐print repositories were searched MPT studies that examined cross‐sectional relationship between frequency quantity of use, problems, dependence, five indicators: intensity (i.e. unrestricted consumption), O max maximum P price at which demand becomes elastic), breakpoint consumption ceases), elasticity sensitivity rising costs). Random effects meta‐analyses effect sizes conducted, with Q tests examining differences by variables, meta‐regression test quantitative moderators, publication bias assessment. Moderators included sex, number prices, variable transformations, year publication. Populations community clinical samples. Results searches yielded 14 ( n = 4077, median % females: 44.8%: weighted average age 29.08 [SD 6.82]), published 2015 2022. Intensity, , showed most robust (| r 's| 0.147–325, p s < 0.014) largest significant | 0.325) dependence 0.320, 0.305, 0.303). Higher proportion males was associated increased estimates elasticity‐quantity ‐problems. prices significantly altered magnitude suggesting biased estimations if excessively low are considered. Methodological quality generally good, minimal evidence observed. Conclusions marijuana purchase task presents adequate demand, robustly intensity, elasticity. Moderating sex suggest potentially meaningful cannabis.

Behavioral economic demand for cannabis is robustly associated with consumption and use disorder (CUD). However, few studies have examined the processes underlying individual differences in relative valuation of (i.e., demand). This study associations between executive functions among young adults who cannabis. We also indirect CUD symptoms through demand. Young (

Lessons Learned in Developing a Behavioral Economic Measure of Cannabis Use Using a Predominantly White Sample

Assessment, Год журнала: 2024, Номер unknown

Опубликована: Авг. 29, 2024

Behavioral economic approaches to measuring cannabis demand represent a well-validated, low-cost method of assessing risk for hazardous use. One widely used measure is the Marijuana Purchase Task (MPT), which has shown good psychometric properties across multiple samples. However, preliminary data suggest that changes could improve task ecological validity and acceptability. Using predominantly White convenience sample, this study aimed develop revised MPT uses modern dispensary scenario better reflect national trends in use (e.g., forms consumption). Participant inattentiveness due increased length difficulty estimating purchases next month may have impacted measures. Lessons learned are discussed inform future efforts assess manner more reflective naturalistic use: including minimizing participant burden, setting higher price ceilings increase utility, considering person-level factors influence demand.

Acute Stress Effect on Delay Discounting and Cannabis Demand among Individuals Endorsing High-frequency Cannabis Use

Limited research examines the effect of stress on behavioral economic constructs among individuals using cannabis. This study examined whether effects acute delay discounting differed in terms cannabis use status and demand changed after induction. Participants were two groups (n = 39 endorsing high-frequency n 48 not use) young adults (75.86% female, 67.82% White, M age 21.64 years). During an online Zoom session, participants completed a prestress assessment, Trier Mental Challenge Test (TMCT) induction, then poststress assessment. Subjective increased significantly across induction (p < .001, ηp2 .23); no group X time interaction was observed. There differences or groups. For only, intensity .006, d .50), but other indices, following Coping motives did moderate association between change subjective any indices group. Cannabis might exert more influential role than shaping decisions related to while experiencing stress. However, practical implications this finding warrant further due relatively small difference hypothetical Study design limitations that could impact findings lead null results are discussed inform future research.
