Objective: Affective experiences are associated with smoking urges and behavior. Few studies have examined the temporal nature of these associations within a day, such as whether positive and negative affect in the morning are associated with smoking urges and behavior later in the day.

Method: Participants (N = 63; M_Age = 50 years, 48% female; 60% White) were randomized into one of three smoking cessation interventions and answered up to five daily ecological momentary assessments for 28 days during a quit attempt (M = 21.0 days, SD = 7.1). Before analysis, scores for morning positive and negative affect and later-day smoking urges and behavior were calculated.

Results: On days when individuals' morning positive affect was higher than usual, later-day smoking urges tended to be lower than usual. In contrast, on days when individuals' morning negative affect was higher than usual, later-day smoking urges tended to be higher than usual, and smoking was more likely. Further, individuals who had higher characteristic morning positive affect tended to have less intense later-day smoking urges, whereas those who tended to have higher characteristic morning negative affect tended to have more intense later-day smoking urges.

Conclusions: Morning positive and negative affect were associated with later-day smoking urges, and morning negative affect was related to later-day smoking behavior. Future research should examine whether interventions that boost positive affect on mornings when it is lower than usual and attenuate negative affect on mornings when it is higher than usual, may reduce the intensity of smoking urges and the likelihood of smoking later in the day.

Objective: Nonspecific relational factors, such as therapist empathy, play an important role in therapy effectiveness. Building on this literature, some researchers have attempted to incorporate relational factors into electronic brief interventions (e-BIs) by using interactive narrators to guide participants through the intervention. However, few studies have examined which characteristics of these interactive narrators increase intervention acceptability and efficacy. The present study sought to systematically manipulate animated narrator characteristics in an e-BI and to examine their effects on respondents' alcohol use and subjective reactions.

Method: Participants (N = 348) were randomly assigned to 1-16 possible combinations of four narrator-level characteristics in a 2 × 2 × 2 × 2 factorial trial evaluating narrator empathy, self-disclosure, gender, and the use of brief motivational interviewing (BMI) techniques. We measured main and interaction effects of these characteristics on the primary outcome of typical drinks per week at 1-month follow-up. Secondary outcomes included maximum drinks, alcohol consequences, and subjective reactions to the intervention, with additional secondary analyses evaluating moderation by participant gender.

Results: Participants showed reductions in all alcohol outcomes. These reductions were stronger for participants exposed to either narrator disclosure or BMI techniques (vs. neither). Participants in the high empathy condition rated the intervention as more supportive, while those exposed to BMI techniques reported feeling more criticized by the intervention.

Conclusions: Specific narrator-level characteristics, such as narrator self-disclosure and empathy, may improve the efficacy or acceptability of e-BIs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Despite the potential for negative consequences, young adults continually engage in heavy alcohol use. Unplanned (vs. planned) drinking has been of particular interest in several studies, as it is theoretically suggested to be related to poor behavioral regulation and negative consequences. Ecological momentary assessment and daily diary (DD) studies have been used to examine the contexts and consequences of planned and unplanned drinking specifically, resulting in somewhat mixed findings surrounding the factors contributing to and consequences of planned drinking. The present DD study adds to this literature by studying rewarding incentives and physical contexts of planned versus unplanned alcohol use, as well as the experiences, or consequences, of planned drinking events.

Method: Ninety-nine young adults took part in a mobile study investigating drinking decisions for the current day and day prior, reporting the rewarding incentives contributing to their decision, the context of drinking events, and the experience of each event.

Results: Planned drinking was associated with being influenced by social/party and alcohol incentives, as well as being at a bar and pregaming. There was a positive relationship between planned drinking and subjective level of intoxication, but not negative or positive experience.

Conclusions: Planned drinking is likely associated with rewarding incentives and social contexts and may contribute to higher levels of subjective intoxication. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Sexually aggressive behavior (SAB), risky sexual behavior (RSB), and heavy episodic drinking (HED) are serious behavioral health problems among college men. The present study substantially revises and validates protective behavioral strategies (PBS) measures in the SAB and RSB domains; evaluates the relations among PBS usage in the SAB, RSB, and HED domains; and determines whether college men with SAB, RSB, or HED histories report lower PBS usage.

Method: College students who identified as men (n = 1,121) completed measures of PBS, SAB, RSB, HED, rape-supportive attitudes, sociosexuality, and bar/party attendance.

Results: Factor analyses resulted in three PBS scales (SAB, RSB-General, and RSB-Protection) that showed good fit and cross-validated well. Average scores for all four PBS measures converged moderately to strongly. Men reporting histories of SAB, RSB, or HED reported much lower domain-specific PBS use, and domain-specific PBS predicted concurrent SAB, RSB, or HED in the presence of other established predictors.

Conclusions: Four well-developed and validated PBS measures now provide an expanded set of potential harm-reduction strategies for college men who drink and engage in sexual activity. Given the strong concurrent associations between PBS use and problems, as well as the interrelatedness of PBS use across domains, future research should examine the impact of simultaneous personalized normative feedback on PBS use across alcohol and sexual domains.

Objective: The timeline follow-back interview is a common method of collecting daily cigarette consumption (cigarettes per day [CPD]) in smoking research. However, it may be subject to recall bias due to its reliance on retrospective reports. The increasing ownership of smartphones allows researchers to administer app-based digital diaries (DD) to collect CPD, which is expected to have less recall bias. Several studies have compared these two methods and found a noticeable discrepancy between them. However, these studies have mainly focused on the time window when smokers were smoking ad libitum. In this study, we wanted to determine the comparability of these two methods when treatment-seeking smokers are attempting to quit smoking.

Method: In a cessation trial, treatment-seeking smokers (n = 251) reported their CPD using the timeline follow-back and DD methods over a 12-week treatment period. To evaluate the comparability, we used the Bland-Altman comparison approach for agreement, correlational analysis between CPD and biochemical measures, digit bias, and logistic regression for predicting abstinence.

Results: We found that the two methods exhibited good agreement, and the agreement did not vary as a function of consumption levels. Consistent with this agreement, CPD data from both methods showed similar correlations with biochemical measures of smoking and predicted 6-month abstinence in a comparable fashion. Despite the agreement, the DD method appeared to be more precise by having a lower digit bias than the timeline follow-back method.

Conclusions: Capturing smoking behavior using either TLFB or DD approaches yields similar data while smokers are attempting to quit smoking. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Investigate the effect of change talk (CT) within successive brief motivational interventions (BMIs) as a mechanism of change for alcohol use.

Method: We conducted a secondary analysis of data from a randomized controlled trial in which 344 young adults (18-35 years old) admitted to a Swiss emergency department with alcohol intoxication received either BMI (N = 171) or brief advice (N = 173). Participants with a baseline audio-recorded BMI were included (N = 140; median age 23 [Q1-Q3: 20-27], 72.9% men). Up to three booster sessions by phone were offered at 1 week, 1 month, and 3 months. Percent CT and CT Average Strength were used as predictor variables. The outcome was the number of heavy drinking days (HDD) over the 30 days prior to research assessments at 1-, 3-, 6-, and 12-month follow-up. A latent growth curve modeling framework was first used to estimate predictor and outcome variable growth parameters (i.e., intercept and slope) over time, and then to regress HDD growth parameters on CT growth parameters.

Results: CT increased specifically from baseline to the 1-week booster session and thereafter remained stable. Higher baseline CT was associated with lower HDD at 1 month (Percent CT: b = -0.04, 95% confidence interval [-0.06, -0.01]; Average Strength: b = -0.99 [-1.67, -0.31]). An increase in CT from baseline to the 1-week booster session was related to a decrease in HDD from 1 month to 12 months (Percent CT: b = -0.08 [-0.14, -0.03]; Average Strength: b = -2.29 [-3.52, -1.07]).

Conclusions: Both baseline CT and CT trajectory over the first week are meaningful predictors of HDD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Individuals are often inaccurate at estimating levels of intoxication following doses of alcohol. Previous research has shown that when required to estimate (BAC) at different time points, participants often underestimate their BACs and amounts of alcohol consumed. The present study aimed to increase drinkers' BAC estimation accuracy after drinking alcohol using mindfulness-based feedback to increase their awareness of the interoceptive cues associated with alcohol intoxication.

Method: Thirty-three adults were given 0.65 g/kg of alcohol and received one of three training conditions: BAC feedback only, body scan exercise + BAC feedback and no treatment control. Those in the BAC feedback group received feedback concerning their observed BAC during dose exposure. Participants in the body scan group received BAC feedback and underwent a mindfulness exercise to enhance their perception of the acute subjective effects of alcohol. The control group received no BAC estimation training. Participants attended four study sessions: Two training sessions where participants underwent structured training based on their condition and two retention sessions to test for the lasting effects of the training exercises.

Results: Retention tests showed that participants in both treatment groups were most accurate in estimating their BACs. There were no differences among the groups in their perceived levels of intoxication at posttraining. The findings suggest that BAC feedback, alone and in combination with, mindfulness training can improve accuracy in estimating BACs.

Conclusions: The findings provide preliminary support for the efficacy of mindfulness training in combination with BAC feedback to improve BAC estimation accuracy. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Subjective intoxication (SI) when drinking may serve as an internal barometer of whether to continue drinking or engage in potentially unsafe behavior. Mobile assessments offer the potential to use SI as a prospective risk indicator during drinking episodes; little evidence exists for the validity of real-time SI measures. We test the correspondence of SI with estimated blood alcohol concentration and transdermal alcohol concentration (TAC) in young adults' natural settings. We provide a novel test of whether SI features (peak and mean SI) uniquely predict consequences adjusting for alcohol concentration.

Method: Two hundred twenty-two heavy-drinking young adults (M_age = 22.3, 64% female, 79% non-Hispanic White, 84% undergraduates) participated in a 6-day study that used ecological momentary assessment of drinking and TAC sensors. SI was assessed every 30 min during drinking episodes. Multilevel modeling was used to test hypotheses.

Results: Momentary SI and estimated blood alcohol concentration had moderate associations at the moment and day levels (standardized βs = 0.5-0.6); SI was moderately associated with TAC at the day level (βs = 0.5). Associations between SI and alcohol concentration varied widely between persons and across days. Day-level SI features predicted consequences when adjusting for alcohol concentration (incidence rate ratios, IRRs = 1.29-1.70).

Conclusions: Our two-item SI measure shows evidence of validity in real-world settings with heavy-drinking young adults. SI was significantly correlated with alcohol concentration and was a unique predictor of consequences. The strength of these associations varied greatly across persons and days. Real-time SI measurement may be useful in preventive interventions, but continued research is needed into when and for whom momentary SI is most predictive of risk.

Objective: The present study examined the independent and joint effects of bullying victimization and sexual harassment victimization on adolescent alcohol use over time within a community sample of adolescents.

Method: Adolescents aged 13-15 years old at baseline (N = 800, M_age = 14.42, SD = 0.83; 57.5% female) recruited from Western New York State made five online survey reports of peer victimization and alcohol use over a 2-year period. Latent class growth analysis was used to identify trajectory classes of victimization from bullying and sexual harassment over time, and regression modeling was used to examine the associations with later alcohol use.

Results: Three developmental courses were identified for bullying victimization (moderate/decreasing, high/decreasing, never or low) and for sexual harassment victimization (moderate/decreasing, moderate/increasing, never or low). Adolescents in the moderate/decreasing group of bullying victimization subsequently consumed more alcoholic drinks when they drank. Belonging to the moderate/increasing group of sexual harassment was associated with increased later alcohol intoxication and number of drinks. Bullying victimization and sexual harassment victimization were concurrently correlated over time. Adolescents who followed the joint trajectory group of moderately decreasing bullying and increasing sexual harassment were more likely to report increased later alcohol intoxication and number of drinks.

Conclusions: Moderate levels of bullying victimization along with increasing sexual harassment victimization are associated prospectively with greater alcohol use in adolescence. Findings highlight the importance of considering the cumulative, joint effects of multiple types of peer victimization on adolescent health outcomes.

Objective: Emotions play a critical role in health risk behaviors, including substance use. However, current research often focuses exclusively on average levels of positive and negative affect, neglecting the complexity of daily emotional patterns. By capturing multiple dimensions of affect, including arousal and discrete states, we can improve our understanding of proximal predictors of substance use. The present study demonstrates the utility of a novel methodological approach for assessing affect patterns in daily life in relation to alcohol and cannabis use.

Method: Daily diary data from N = 154 young adults who reported recent heavy episodic drinking and simultaneous use of alcohol and cannabis were analyzed using a mixed-indicator latent profile analysis to identify and describe day-level affective patterns and outcomes.

Results: Results revealed five distinct day-level profiles of affect: undifferentiated negative affect days, undifferentiated positive affect days, high-arousal positive affect days, mixed affect days, and low reactivity days. Undifferentiated positive affect days, high-arousal positive affect days, and low reactivity days were associated with significantly greater odds of same-day alcohol use compared to days characterized by undifferentiated negative affect (χ² = 10.55, p = .032).

Conclusions: Findings suggest that daily affect patterns differentially impact alcohol use and can inform the development of interventions for problematic substance use. Additionally, the innovative methodological approach employed herein could be applicable for investigating the role of emotion in other health behaviors.
