“…Furthermore, recent research has contested the validity of the single-item breakpoint measure 48 thereby contrasting conclusions from prior research that informed the present study protocol 32 . Self-report tobacco demand should therefore be interpreted cautiously in the present study.…”

Introduction: A considerable number of people successfully give up tobacco smoking. Tobacco choice in nicotine dependent individuals is determined by greater expected drug value; however, less is known about the underlying mechanisms through which people quit smoking. The aim of this study is to explore whether computational parameters of value-based decision-making characterise recovery from nicotine addiction. Methods: This study was pre-registered. Using a between-subject design, current daily smokers (n = 51) and ex-smokers who used to smoke daily (n = 51) were recruited from the local community. Participants completed a two-alternative forced choice task in which they chose between either two tobacco-related images (in one block) or tobacco-unrelated images (in a different block). On each block, participants pressed a key to select the image that they had rated most positively during a previous task block. A drift-diffusion model was fitted to the reaction time and error data to estimate evidence accumulation (EA) processes and response thresholds during the different blocks. Results: Compared to current smokers, ex-smokers had significantly higher response thresholds when making tobacco-related decisions (p = .01, d = .45), although there were no significant group differences during tobacco-unrelated decisions. Furthermore, there were no significant group differences in EA rates when making tobacco or tobacco-unrelated decisions. Conclusions: Recovery from nicotine addiction is characterised by greater cautiousness when making value-based decisions about tobacco-related cues.

“…To assess convergent validity, bivariate correlations of demand indices on the BAMD, the MPT, and cannabis outcome measures were conducted using IBM statistical products and service solutions (SPSS) Statistics for Windows, Version 26.0 (IBM Corp., Armonk, NY). To assess divergent validity, independent samples t tests were conducted to examine whether BAMD indices differed based on the presentation or absence of CUD symptoms using DSM-5 criteria (APA, 2013;First et al, 2015). Next, three one-way between-subjects analyses of variances (ANOVAs) with planned comparisons compared CUD severity (i.e., mild, moderate, severe) based on BAMD intensity, O max , and breakpoint.…”

“…The Brief Assessment of Cigarette Demand (Murphy et al, 2019) and a cigarette purchase task (CPT) showed similar associations between demand and tobacco-related variables for two demand indices but differed on the third. Another study conducted with individuals seeking treatment for their tobacco use found that while a single-item breakpoint measure was correlated with all demand indices from the full CPT, it did not correlate with nicotine dependence severity (González-Roz et al, 2021). While more work is needed in this area, these initial validation studies demonstrate the potential of brief assessment measures to capture demand for a substance and their brevity may facilitate increased use in clinical and research settings.…”

Hypothetical purchase tasks assess substance demand, but the length of purchase tasks makes repeated assessment of state-dependent changes in demand difficult, often limiting clinical utility. Although brief assessments of alcohol and cigarette demand exist, brief measures of cannabis demand do not. College students (N = 209, M age = 19.92, SD = 1.45; 63% female; 56.9% non-Hispanic Caucasian) who reported using cannabis at least 3 days in the past month, completed an online survey including the full-length marijuana purchase task (MPT), a three-item brief assessment of marijuana demand (BAMD) assessing intensity, O max and breakpoint, and cannabis use outcomes. Convergent and divergent validity were examined. Independent samples t tests compared demand on the BAMD and MPT based on presence or absence of cannabis use disorder (CUD) symptoms, and one-way between-subject analyses of variance compared effects of CUD severity (mild/moderate/severe) on BAMD indices. All indices were significantly correlated across both assessment measures ( ps < .01). Similarly, all indices on both demand measures were significantly correlated with craving, CUD severity, and cannabis-related consequences ( ps < .01); whereas only intensity and O max were significantly correlated with cannabis use frequency ( ps < .01). Individuals with (vs. without) CUD symptoms reported significantly greater intensity and O max ( ps < .01) and significant differences in CUD severity on BAMD indices were found as well ( ps < .05). The BAMD demonstrated convergent and divergent validity with the MPT. Findings suggest that brief cannabis demand can be easily assessed as an indicator for high-risk cannabis use. Thus, the BAMD may be a useful and clinically relevant tool to assess cannabis demand in real-world settings. Public Health SignificanceThis study demonstrated that a brief assessment of marijuana demand (BAMD) differentiated individuals based on presence or absence of cannabis use disorder symptoms. The BAMD was significantly associated with corresponding demand indices on the marijuana purchase task and is a useful tool to assess cannabis demand in clinical and real-world settings.
