Numerous nonlinear models derived from the framework of Hursh and Silberberg (2008) are often applied to elucidate key metrics in the operant demand framework (e.g., Q₀, PMAX), with each approach presenting respective strengths and trade-offs. This work introduces and demonstrates an adaptive task capable of elucidating key features of operant demand without relying on nonlinear regression (i.e., a targeted form of empirical PMAX). An adaptive algorithm based on reinforcement learning is used to systematically guide questioning in the search for participant-level estimates related to peak work (e.g., PMAX), and this algorithm was evaluated across four varying iteration lengths (i.e., five, 10, 15, and 20 sequentially updated questions). Equivalence testing with simulated agent responses revealed that tasks with five or more sequentially updated questions recovered PMAX values statistically equivalent to seeded PMAX values, which provided evidence suggesting that quantitative modeling (i.e., nonlinear regression) may not be necessary to reveal valuable features of reinforcer consumption and how consumption scales as a function of price. Discussions are presented regarding extensions of contemporary hypothetical purchase tasks and strategies for extracting and comparing critical aspects of consumer demand.

This study evaluated the impact of providing adults who smoke with both very low nicotine content cigarettes (VLNCCs) and electronic cigarettes (ECs) of varying nicotine content on measures of human abuse potential. Participants (n = 213) were adult combustible cigarette users. They smoked their usual brand cigarettes (UBCs) during Phase 1 (baseline; week 1) and were provided with and encouraged to exclusively use VLNCCs during Phase 2 (weeks 2-4). During dual-product Phases 3 (weeks 5-7) and 4 (weeks 8-10), participants received both VLNCCs and ECs (assigned to one of two EC devices in higher or lower nicotine concentrations and choice of flavor), with instructions to use them freely in Phases 3 and 4. Assessments included product use, exposure, acceptability, risk perception, and withdrawal-related measures. Results indicated that participants used significantly fewer UBCs during the VLNCC and dual-product phases and smoked fewer VLNCCs during the dual-product phases than the VLNCC-only phase. Neither EC liquid nicotine concentration nor flavor influenced product use. The three study product phases resulted in less product liking and more withdrawal symptoms than the UBC phase. These results suggest that adults who smoke are able to switch much of their tobacco product use from UBCs to VLNCCs and will substitute combustible UBCs and VLNCCs with noncombustible nicotine-containing ECs, but most remain dual users, at least in the short term.

Regression models tested hypothesized associations between frequency of public posting and alcohol outcomes. Subsequent models assessed simple effects by race/ethnicity (Hispanic, Black, White) and gender (man, woman). Controlling for covariates, more frequent public alcohol-posting was associated with higher USAUDIT, HED frequency, and HID likelihood, not consequences. For Hispanic YA, posting was positively associated with all outcomes except consequences. For Black YA, posting was positively associated with USAUDIT and HID, not HED or consequences. For White YA, posting was positively associated with USAUDIT and HED, not HID or consequences. For women, posting was positively associated with USAUDIT total, HID, and consequences. For men, posting was positively associated with USAUDIT and HED. In conclusion, more frequent public alcohol-posting on SNS was positively associated with past-year alcohol use and problems, implying potential to screen for hazardous drinking via public SNS posts, among non-college-attending YA.

Episodic future thinking (EFT), a cognitive intervention involving imagining future events, has been shown to reduce cigarette craving, demand intensity, and self-administration among cigarette smokers but has not been tested with e-cigarette users. This study tested if a brief EFT intervention decreases delay discounting and smoking choice using a within-subjects experimental design administered via Zoom. Daily young adult e-cigarette users attended a baseline session and two counterbalanced experimental sessions: (a) EFT in which participants preexperienced and described positive future events and (b) standardized episodic thinking, a control intervention in which participants described their experiences watching three short videos. Measures of craving, mood, and delay discounting across three commodities: Money, e-cigarette products, and food were completed pre- and postmanipulation. As predicted, monetary delay discounting showed a greater decrease following EFT relative to standardized episodic thinking (p = .006; ηp² = .229). There were no effects on craving or mood. Participants also completed a 40-min vaping versus money choice task. Approximately 70% of participants chose to abstain for the full 40 min after EFT compared to 60% after the control condition, a nonsignificant difference (p = .184). Additional research is needed to support the efficacy of EFT as an intervention for helping e-cigarette users increase their ability to abstain. The study demonstrates the feasibility of conducting experimental research on e-cigarettes in a virtual setting.

The literature has shown robust acute negative effects of cannabis on cognition and psychomotor skills during intoxication, and to a lesser degree, persisting effects following short-term abstinence up to 4 weeks. However, whether these decrements resolve after long-term cessation of use remains unclear. We evaluated cognitive and psychomotor function in 31 adults with current cannabis use during unrestricted use (UNR) and after a 3-day abstinence (RES), 23 adults with former cannabis use (> 90 days abstinent; FU), and 58 nonusing controls (CON) using the cognition and motor batteries of the National Institutes of Health Toolbox. Linear mixed models showed no significant differences in cognitive and motor performance between UNR, RES, and FU groups. Group effects emerged such that CON outperformed UNR on the Oral Reading Recognition Test, and CON outperformed both UNR and RES on the Picture Vocabulary Test. In terms of psychomotor function, FU, RES, and UNR performed better than CON on the Grip Strength Test. In this comprehensive examination of cognitive and psychomotor performance in adults with cannabis use with 3 days to > 90 days of abstinence, our results indicated that the cognitive impacts of chronic, heavy cannabis use are observable during short-term abstinence but remit after > 90 days of abstinence. This highlights widespread impacts of cannabis use abstinence across cognitive and psychomotor domains. Future studies are needed to evaluate whether these effects are also observable with use reduction, as opposed to abstinence.

Though measures have been validated to assess alcohol- and cannabis-specific PBS use, an opioid-specific PBS measure has yet to be validated. The present study developed and validated a tool to assess the extent of PBS employed by individuals who use licit and/or illicit opioids. We recruited a community sample of adults who endorsed past-month opioid use (n = 345) via online platforms to complete a baseline survey, and 277 participants (80.2%) also completed the 1-month follow-up survey. From PBS measures of other substances, harm reduction strategies found in the literature, and expert feedback, we developed the 60-item Opioid Protective Behavioral Strategies Scale (OPBSS). We removed 14 items based on item and exploratory factor analyses, resulting in 46 retained items. A two-factor solution was supported: strategies focused on managing opioid use (Controlled Opioid Use) and preventing opioid-related harm (Serious Harm Reduction). The OPBSS subscales demonstrated high internal consistencies, fair-to-excellent test-retest reliability, significant positive associations with PBS measures for other substances, and robust associations with risky opioid use and opioid-related negative consequences, both concurrently and prospectively when controlling for other opioid characteristics. The 46-item OPBSS has promising psychometric properties. Importantly, more opioid PBS predicted less risky opioid use and related consequences, suggesting that opioid PBS may be a beneficial opioid prevention effort.

Previous experimental studies have shown that students exposed to a stressor, compared to those not exposed to a stressor, drink more and have stronger urges to drink, presumably to cope with the stressor. However, no such study has tested this effect using a remote-based stressor, which may be more common for students because of the recent increase in online learning. As such, the present study aimed to (a) test the impact of an acute stressor on state anxiety and alcohol craving and (b) investigate trait-level drinking characteristics as potential moderators of the impact of the acute stressor. Participants were 137 (Mage = 19.9, SDage = 2.0; 82.5% female; 41.6% White) college students who consumed alcohol in the past month. Using a between-subjects experimental design, we assigned participants randomly to an experimental (i.e., acute stress) condition or control (i.e., neutral) condition, and they completed a premanipulation battery of alcohol-related attitudes and behaviors and a postmanipulation measure of alcohol craving. On average, participants in the experimental condition reported greater increases in anxiety than those in the control condition, but there were no differences found in alcohol craving. However, for both anxiety and craving, greater increases from pre- to postmanipulation were found when trait-level anxiety and trait-level drinking were high, respectively. Thus, heavier drinking college students may be at greater risk for craving alcohol in response to stress than those who typically drink less.
