“…Hypothetical choice also allows for use in populations for whom drug self‐administration is impractical or not ethically feasible. Existing systematic reviews and a meta‐analysis of the alcohol purchase task have highlighted this construct validity and flexibility for alcohol research.…”

Background andAims The commodity purchase task is a simulated demand procedure that is easy and quick to complete (< 5 minutes) as well as adaptable for remote delivery and use with varied study populations. The purpose of this meta‐analysis was to synthesize research using the commodity purchase task with illicit substances to evaluate the magnitude of omnibus effects sizes and moderators of the correlation of demand indices with quantity–frequency (QF) and severity measures. Design Random‐effects meta‐analyses and meta‐regressions involving studies with cross‐sectional correlational designs. Setting and Participants Eleven studies, 10 outcomes and 2146 participants from two countries (USA and UK) published up to 1 October 2018. Measurements Omnibus effect sizes (correlation coefficients) of five demand indices from the commodity purchase task [intensity (unconstrained consumption), elasticity (price sensitivity), Omax (maximum expenditure), Pmax (price at maximum expenditure) and breakpoint (first price of zero consumption)] with QF and severity measures. Meta‐regression models tested moderators of effect sizes (i.e. sample age and sex composition, commodity type and number of prices used in the commodity purchase task). Findings Significant omnibus effect sizes were observed with QF and severity measures for intensity (r = 0.32/0.28, QF/severity, respectively), elasticity (r = −0.14/−0.18), Omax (r = 0.30/0.29) and breakpoint (r = 0.17/0.22) values. Pmax was only significantly associated with severity measures (r = 0.15). The percentage of female participants and number of prices used in the purchase task significantly moderated Pmax and breakpoint effect‐size estimates in that stronger associations were observed in samples with a greater percentage of women and in studies using tasks with more price points. Commodity type (cannabis versus cocaine) did not significantly moderate associations involving any demand index. Conclusions Behavioral economic demand as measured by the commodity purchase task is consistently correlated with measures of illicit substance use quantity–frequency and severity.

“…Research in addiction science has established that the commodity purchase task provides a reliable, stimulus‐selective, and construct‐valid measure of valuation for a variety of drugs and drug classes (Kaplan et al, ; MacKillop, ). The clinical utility of the procedure has also been demonstrated wherein demand measures have been used to identify behavioral mechanisms underlying effective interventions (Bujarski, MacKillop, & Ray, ; McClure, Vandrey, Johnson, & Stitzer, ) or functioned as prognostic variables predictive of treatment efficacy (MacKillop & Murphy, ; Murphy et al, ).…”

Behavioral economic theory has proved useful for understanding the influence of delay and probability on sexual health decision‐making. Demand is another principle at the intersection of microeconomics and psychology that has helped advance research relevant to health behaviors. The purpose of the present study was to develop and test a demand measure related to sexual health decision‐making and the influence of sexually transmitted infection (STI) risk. Participants (N = 438) recruited using Amazon Mechanical Turk completed a commodity purchase task assessing hypothetical condom demand. Condom demand was evaluated at varied prices for use with hypothetical sexual partners that varied in STI risk. Demand was characterized by prototypic decreases in consumption with increases in cost. Higher partner STI risk was associated with greater intentions for condom‐protected sex at no cost and smaller decreases in condom demand with increases in cost. Price sensitivity was also related to individual difference factors relevant to sexual health (e.g., alcohol use severity, lower STI knowledge). This study supports the utility of a condom purchase task for indexing condom valuation and capturing individual difference and contextual risk factors relevant to STI transmission. Future studies may leverage this methodology as a means to study sexual health decision‐making.

“…The only exception is the study conducted by Kiselica et al 13 who examined whether estimates differed as a function of drinking status (regular vs heavy drinkers). More recently, several potential moderators have been proposed by Kaplan et al 3 in a recent methodological review of the APT literature, suggesting that either the heterogeneity of participants (ie, adults or college-age participants) or task structural characteristics (ie, vignette framing, number of prices or amounts used) might impact on demand estimations. A recent meta-analysis on the concurrent validity of illicit purchase tasks has shown that sex and number of prices used are significant moderators of the relationship between P max , breakpoint and quantity and severity measures.…”

“…1 2 Framed from the perspective of behavioural economics, the APT measures participants' demand across a variety of prices, either as a trait-like process (ie, in a typical drinking situation) or as a statelike process (ie, right now) scenario. 3 Data from the APT allow generating a demand curve depicting the relationship between consumption and unit price. 4 More precisely, the value of the APT lies on its multidimensional characterisation of the incentive value of alcohol which captures, as per principal component analyses, the persistence (ie, O max or maximum expenditure, price associated to the maximum expenditure or P max , breakpoint defined as price at which consumption ceases and sensitivity of demand to increases in costs, known as elasticity) and the amplitude of demand (ie, intensity or consumption at no cost and O max ) facets.…”

IntroductionAlcohol demand, as measured by an alcohol purchase task (APT), provides a multidimensional assessment of the relative reinforcing efficacy of alcohol. The objective of this meta-analysis is to critically appraise the existing literature on the concurrent validity of the APT by meta-analysing the cross-sectional relationships between indices of the APT (ie, breakpoint, Omax, Pmax, elasticity and intensity) and alcohol-related measures. It also aims to examine methodological procedures used to obtain APT indices and individual variables as potential moderators on the assessed estimations.Methods and analysisA comprehensive literature search conducted from inception to April 2020 will be conducted in the PubMed, PsycINFO, Web of Science and Scopus databases. Two authors will independently screen and extract data from articles using a predefined protocol search and extraction forms. Disagreements will be resolved through discussion with two additional reviewers. All results will be tabulated, and a random-effect meta-analysis will be conducted. Participants’ sex, number of prices and APT methodological procedures will be examined as potential moderators on the observed effect sizes.Ethics and disseminationResults of this meta-analysis will characterise the concurrent validity of the APT in the existing literature. Further, the results are anticipated to provide evidence on which index (or indices) is most robustly associated with alcohol use and severity. Ethics approval was not required for this study and the results will be published in a peer-reviewed journal.PROSPERO registration numberCRD42019137512
