Psychology of Addictive Behaviors最新文献

Objective: In addiction-focused clinical and public health communications intended to educate the public, assumptions are made regarding in which specific knowledge aspects the target population is deficient, so these can be emphasized and harms minimized. It is rare, however, that outreach campaign messaging is based on specific known knowledge deficits. This lack of information can lead to prevention and intervention messaging that not only fails to gain target audiences' attention but can produce unintended consequences. Greater knowledge about information deficits could enhance the impact of addiction-specific health campaigns.

Method: Cross-sectional investigation involving members of the public (N = 1,257) sampled via the Prolific platform. Participants listed their top 10 questions pertaining to one of six different types of addiction problems (addiction-general [n = 211], alcohol [n = 209], cannabis [n = 209], cocaine [n = 211], opioids [n = 214], gambling [n = 209]). Results were categorized using qualitative thematic and grounded theory and ranked according to proportional frequency.

Results: Types of questions asked fell into nine domains (e.g., etiology, clinical characterization and course, drug characteristics, pharmacology) and subdomains, with topics varying substantially within addiction type (e.g., cannabis, opioids) across domains (e.g., etiology, treatment), as well as within domains across types. Differences in the proportion of types of questions asked across and within domains were highly variable differing across addiction types (i.e., cannabis, opioids, gambling).

Conclusions: Findings have implications for clinical and public health campaigns helping to highlight more precisely the exact nature and extent of potential population-level knowledge deficits across specific addiction types. These might be prioritized and targeted in knowledge dissemination efforts for prevention and treatment engagement. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: The female menstrual cycle and associated fluctuations in ovarian hormones are an important biological context that likely influences emotion-focused smoking. The present study evaluated the role of emotion regulation difficulties on daily emotional distress and cigarette craving in the context of the perimenstrum (i.e., days before and during menses).

Method: Naturalistic daily data were collected from non-treatment-seeking naturally cycling females (N = 50, M_age = 32.3, SD = 5.3) who reported daily cigarette smoking. Ecological momentary assessment of anxiety, mood, and cigarette craving was collected while also tracking the menstrual cycle. Days were coded as either occurring during perimenstrum (i.e., 7 days prior to and first 3 days during menses) or reference (i.e., all other days). Trait difficulties with emotion regulation were assessed at baseline.

Results: Multilevel models indicated a significant effect of emotion regulation difficulties on daily emotional distress (i.e., anxiety, negative mood), specifically on perimenstrual days. A second set of multilevel models was conducted to model the influence of daily emotional distress on cigarette craving specifically during perimenstrual days. Significantly higher daily craving was reported on perimenstrum days characterized by higher negative mood relative to lower negative mood, but this effect was only statistically significant in the context of greater emotion regulation difficulties.

Discussion: The menstrual cycle, its associated ovarian hormone fluctuations, as well as individual differences in the response to emotion should be considered as important female-specific determinants of emotion-focused smoking. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Suicide is a leading cause of preventable death. Problematic alcohol use and service in the U.S. military confer elevated risk for suicide, yet it is unknown whether their combination further heightens the risk. Extant literature is circumscribed to veterans enrolled in Veterans Affairs care, those with diagnosed alcohol use disorder, or suicide mortality, resulting in notable literature gaps on non-Veterans Affairs-enrolled veterans, nondiagnostic problematic drinking behaviors, and premortality suicide risk.

Method: To address these gaps, this study included U.S. adults who participated in the 2015-2020 National Survey on Drug Use and Health, representing 236,723,876 adults. Suicide ideation, planning, and attempt; veteran status; binge drinking, heavy drinking, and demographics were extracted from the cross-sectional self-report survey. Multivariable logistic regression examined suicide ideation, planning, and attempt as a function of veteran status and drinking variables after accounting for relevant demographics.

Results: Veterans and nonveterans who reported binge or heavy alcohol use were more likely to report suicide risk. Veterans who engaged in binge drinking episodes were 33% more likely than nonveterans to report any suicide risk. Veteran males who reported binge alcohol use were 38% more likely than nonveteran males to report any suicide outcome. Veterans who reported binge drinking were 72% more likely to report suicide planning without an attempt relative to nonveterans.

Conclusions: Efforts to reduce suicide planning among veterans reporting binge drinking are critically needed and present one avenue for reducing the likelihood of a suicide attempt or actual death by suicide. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Many existing treatments for gambling disorder grapple with the challenge of losing participants from treatment. Thus, treatments designed to increase adherence and retention would contribute significantly to the existing gambling treatment efficacy literature. Our study steps into the arena with an innovative approach.

Method: We tested the effectiveness of cognitive motivational behavior therapy (CMBT), a treatment for gambling disorder designed not only to address symptoms but also to anchor participants throughout the treatment journey. We enrolled 46 individuals seeking treatment for gambling problems, all meeting the criteria for gambling disorder, and randomly assigned them to undergo 12 sessions of CMBT or to attend at least 12 sessions of Gamblers Anonymous (GA) meetings.

Results: Zero-inflated Poisson regression showed that individuals in CMBT had a 94% probability of completing treatment, with 95.7% attending all 12 treatment sessions and 91.3% completing the 6-month follow-up. Overall, individuals in CMBT gambled less money during follow-up periods relative to baseline than those in GA, F(3, 116.81) = 3.72, p = .01. A secondary moderator analysis revealed that of those participants who were low in readiness to change, only those randomized to CMBT gambled less money, F(3, 110.29) = 3.96, p = .01.

Conclusions: Compared to GA, CMBT was more effective at retaining participants in treatment and reducing the amount of money gambled. For those who began treatment with low readiness to change, CMBT also decreased the severity of problem gambling, which was not the case for those referred to GA.

Objective: Rates of problematic cannabis use among young adults are high and increasing. Craving for cannabis varies throughout the day and is an important risk factor for cannabis use, yet no studies to date have tested interventions offered at the moment craving is experienced in the natural environment.

Method: This study used an efficient and innovative microrandomized trial design to test two distinct types of coping messages (mindfulness strategy vs. distraction strategy) offering brief coping strategies when moderate to severe craving was reported via ecological momentary assessment (EMA).

Results: Young adults who regularly use cannabis (N = 53) were readily engaged in this 4-week intervention, and EMA completion was high throughout, demonstrating excellent feasibility of this approach. However, results indicated that coping messages did not reduce craving at the next EMA relative to control (thank you) messages, with no significant change in efficacy over time. Furthermore, exploratory analyses found that neither mindfulness nor distraction resulted in reduced craving relative to the control message.

Conclusions: Despite this outcome, this method of testing digital interventions targeting momentary risks for substance use such as craving holds promise for rapidly and efficiently screening a wide variety of intervention strategies for inclusion in future just-in-time adaptive interventions.

Objective: Predicting which young people are likely to use tobacco in the future is critical for prevention and intervention. Although measures for assessing susceptibility to using tobacco have fulfilled this goal for decades, there is almost no standard for the number of items that should be administered, or which items should be administered for which products. This study explored whether brief but psychometrically sound versions of commonly used susceptibility measures can adequately capture the construct relative to longer measures.

Method: A sample of young people (N = 451; M_age = 16.5 years; 64% females; 65% White) completed 33 susceptibility items, which are designed to assess susceptibility to use different types of tobacco products (cigarette, smokeless tobacco, vaping products, and little cigars/cigarillos) of various flavors (tobacco, menthol, and sweet).

Results: Analysis of these 33 items indicated that asking about the likelihood of using each tobacco product class when a best friend offers it (four items in all) captures 98.5% of information that is captured using the longer set of items; asking the best friend question for each product by each flavor category (11 items in all) captures 99.7% of the information.

Conclusions: Depending on research needs, tobacco use susceptibility can be measured with little loss of information by administering a limited set of items assessing the likelihood that a young person will use a tobacco product if a friend offers it for any product-flavor combination.

Objective: Research among young adults (YA), in samples of majority White college students, indicates links between posting about alcohol on social media and self-reported drinking behavior. We sought to extend this work by examining unique associations between public versus private posting about alcohol and the high-risk outcome of alcohol-related blackouts among a sample of racially/ethnically diverse YA not in 4-year college.

Method: A sample of 499 participants (ages 18-29; 52.5% female; 37.5% Black/African American, 26.9% White, 25.3% Hispanic/Latinx) completed an online survey about social media use and drinking behavior.

Results: Across three platforms (Instagram, TikTok, Twitter [now known as "X"]), public posting on Instagram was most common. Adjusting for covariates, a higher frequency of private posting about alcohol was associated with a higher frequency of past-month blackouts. Tests of simple effects of posting on blackouts within racial/ethnic subgroups indicated that private posting about alcohol was significantly associated with past-month blackouts only among those who most strongly identified as Black/African American or White but not among those who most strongly identified as Hispanic/Latinx. Further, public posting was significantly associated with past-month blackouts, though the association was specific to White participants.

Conclusions: Whether posting about alcohol may be useful in identifying risky drinking behavior may depend on racial/ethnic identification as well as whether private or public posting is being considered. Results have implications for eventual online interventions, which can identify individuals potentially at risk for hazardous drinking based on their social media posting behavior.

Objective: Transdermal alcohol concentration (TAC) sensors provide a multidimensional characterization of drinking events that self-reports cannot. These profiles may differ in their associated day-level alcohol-related consequences, but no research has tested this. We address this using multilevel latent profile analysis.

Method: Two hundred twenty-two young adults who regularly engage in heavy drinking (M_age = 22.3, 64% female, 79% non-Hispanic White) responded to surveys and wore TAC sensors for 6 consecutive days. We tested whether four previously identified TAC profiles: (1) high-fast (8.5% of days), (2) moderate-fast (12.8%), (3) low-slow (20.4%), and (4) little-to-no-drinking days (58.2%) differed in numbers of negative and positive consequences and in the odds that both consequence types occurred on the same day.

Results: High-fast (incident rate ratio [IRR_low-slow] = 6.18; IRR_{little-to-no-drinking} = 9.47) and moderate-fast (IRR_low-slow = 3.71; IRR_{little-to-no-drinking} = 5.68) days contained more negative consequences compared to low-slow and little-to-no-drinking days. High-fast (IRR = 2.05), moderate-fast (IRR = 1.88), and low-slow (IRR = 1.43) days contained more positive consequences than little-to-no-drinking days. The odds of having only positive consequences were highest on low-slow, χ²(3) = 9.10, p < .05, days but the odds of experiencing both consequence types increased on moderate-fast and high-fast days, χ²(3) = 39.63, p < .001.

Conclusions: Compared to little-to-no-drinking days, TAC profiles indicative of drinking (high-fast, moderate-fast, and low-slow) contained more negative and positive consequences. However, the odds of experiencing only positive consequences were highest among low-slow days and decreased on moderate-fast and high-fast days as the odds of negative consequences rose. These findings provide novel evidence reinforcing harm reduction approaches that seek to maximize positives and minimize negatives of alcohol consumption through emphasis on slow-paced, low-volume drinking.

Objective: Building upon prior research, the present study tested coping motives as a mediator of relations between both negative urgency and internalizing symptoms (depression, anxiety, and stress), and alcohol-related consequences using longitudinal data. We also tested negative urgency as a moderator of prospective relations between specific internalizing symptoms and alcohol-related consequences.

Method: The study utilized data from a longitudinal study of young adults (N = 448; M_age = 22.27, SD = 1.25). Participants (56.5% male) were evaluated at baseline and at 12-month and 24-month follow-ups. Mood, impulsivity, coping motives, and alcohol consequences were assessed at baseline, and motives and consequences were assessed at follow-ups.

Results: Prospective indirect effects of internalizing symptoms and negative urgency on alcohol consequences through coping motives were not observed. However, cross-sectional post hoc analyses indicated that higher levels of internalizing and negative urgency were indirectly associated with greater alcohol consequences through coping motives, with similar patterns observed for depression, anxiety, and stress. Although support was found for mediated effects in the cross-sectional model, no evidence was found for negative urgency moderating the impact of internalizing, stress, anxiety, or depression on alcohol consequences in either cross-sectional or longitudinal models.

Conclusion: Findings provide cross-sectional but not longitudinal support for coping motives as a potential mechanism through which a broad range of internalizing symptoms are associated with alcohol consequences. Findings did not support interactions between negative urgency and internalizing symptoms. The results highlight the need for further exploration of mediated effects using ecological momentary assessments. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Transdermal alcohol concentration (TAC) sensors capture aspects of drinking events that self-reports cannot. The multidimensional nature of TAC data allows novel classification of drinking days and identification of associated behavioral and contextual risks. We used multilevel latent profile analysis (MLPA) to create day-level profiles of TAC features and test their associations with (a) daily behaviors and contexts and (b) risk for alcohol use disorders at baseline.

Method: Two hundred twenty-two regularly heavy-drinking young adults (M_age = 22.3) completed the Alcohol Use Disorders Identification Test (AUDIT) at baseline and then responded to mobile phone surveys and wore TAC sensors for six consecutive days. MLPA identified day-level profiles using four TAC features (peak, rise rate, fall rate, and duration). TAC profiles were tested as correlates of daily drinking behaviors, contexts, and baseline AUDIT.

Results: Four profiles emerged: (a) high-fast (8.5% of days), (b) moderate-fast (12.8%), (c) low-slow (20.4%), and (d) little-to-no drinking days (58.2%). Profiles differed in the odds of risky drinking behaviors and contexts. The highest risk occurred on high-fast days, followed by moderate-fast, low-slow, and little-to-no drinking days. Higher baseline AUDIT predicted higher odds of high-fast and moderate-fast days.

Conclusions: Days with high and fast intoxication are reflective of high-risk drinking behaviors and were most frequent among those at risk for alcohol use disorders. TAC research using MLPA may offer novel and important insights to intervention efforts. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
