Efficacy of Ecological Momentary Intervention Tailored to Drinking Motives for Reducing Problematic Drinking in Young Adults

Background: Brief interventions can inform young problematic drinkers about the risks associated with alcohol use. Ecological Momentary Interventions (EMIs), which provide feedback closer to the point of drinking, may help to translate the internal changes made from these brief interventions into actual behavior.Methods: Thirty-six problematic drinkers aged 19∼34 years were randomly assigned to one of three groups: Ecological Momentary Assessment (EMA), Standard EMI, or Tailored EMI. Participants in all groups completed two daily EMAs for four weeks following a single-session intervention. They reported their drinking intentions and motives for the current day, and their alcohol consumption and drinking motives from the previous day. The Standard EMI group received feedback on the general negative consequences of drinking, while the Tailored EMI group received feedback specifically tailored to their drinking motives based on their EMA responses.Results: Problematic drinking, along with related variables (e.g., drinking behavior, alcohol consumption, negative consequences, alcohol expectancies, and drinking motives) was reduced across all groups.Conclusions: Further research is needed on the potential of monitoring drinking behavior to reduce problematic drinking and how to improve tailored EMI.

Motivation to Abstain from Drinking as a Moderator of Associations Between Parent and Offspring Problem Drinking

Objective Motivational processes are key factors in the development and maintenance of problem drinking and include motivation to drink as well as motivation to abstain from drinking. Although motivation to drink has been widely studied, little research has considered motivation to abstain from drinking. The current study addresses this gap in research by exploring the role of motivation to abstain from drinking based on dispositional risk, fear of negative consequences, religious and family constraints, and indifference to alcohol in associations between mother and father problem drinking and the problem drinking of college students. Method Data were collected from 337 U.S. college students (77.2% female, 86% White) who reported on their exposure to mother and father problem drinking, their own problem drinking, and their motivation to abstain from drinking for several reasons. Results Findings supported the protective role of motivation to abstain from drinking based on fear of negative consequences of drinking. Persons exposed to parental problem drinking who had low motivation to abstain from alcohol based on dispositional risk were vulnerable to the intergenerational transmission of problem drinking. In addition, motivation to abstain from drinking based religious or family constraints was associated with lower problem drinking regardless of exposure to parental problem drinking. Conclusions Conviction-related motivation may be a powerful motivation to abstain from drinking, including among persons at risk due to parental problem drinking.

Support after return to alcohol use: a mixed-methods study on how abstinence motivation and app use change after return to alcohol use in an app-based aftercare intervention for individuals with alcohol use disorder

BackgroundAs the return to alcohol use in individuals with alcohol use disorder (AUD) is common during treatment and recovery, it is important that abstinence motivation is maintained after such critical incidences. Our study aims to explore how individuals with AUD participating in an app-based intervention with telephone coaching after inpatient treatment perceived their abstinence motivation after the return to alcohol use, whether their app use behavior was affected and to identify helpful factors to maintain abstinence motivation.MethodsUsing a mixed-methods approach, ten participants from the intervention group of the randomized controlled trial SmartAssistEntz who returned to alcohol use and recorded this in the app Appstinence, a smartphone application with telephone coaching designed for individuals with AUD, were interviewed about their experiences. The interviews were recorded, transcribed and coded using qualitative content analysis. App use behavior was additionally examined by using log data.ResultsOf the ten interviewees, seven reported their abstinence motivation increased after the return to alcohol use. Reasons included the reminder of negative consequences of drinking, the desire to regain control of their situation as well as the perceived support provided by the app. App data showed that app use remained stable after the return to alcohol use with an average of 58.70 days of active app use (SD = 25.96, Mdn = 58.50, range = 24–96, IQR = 44.25) after the return to alcohol use which was also indicated by the participants’ reported use behavior.ConclusionsThe findings of the study tentatively suggest that the app can provide support to individuals after the return to alcohol use to maintain and increase motivation after the incidence. Future research should (1) focus on specifically enhancing identification of high risk situations and reach during such critical incidences, (2) actively integrate the experience of the return to alcohol use into app-based interventions to better support individuals in achieving their personal AUD behavior change goals, and (3) investigate what type of support individuals might need who drop out of the study and intervention and discontinue app use altogether.Trial registrationThe primary evaluation study is registered in the German Clinical Trials Register (DRKS, registration number DRKS00017700) and received approval of the ethical committee of the Friedrich-Alexander University Erlangen-Nuremberg (193_19 B).

Sex-dependent factors of alcohol and neuroimmune mechanisms

Excessive alcohol use disrupts neuroimmune signaling across various cell types, including neurons, microglia, and astrocytes. The present review focuses on recent, albeit limited, evidence of sex differences in biological factors that mediate neuroimmune responses to alcohol and underlying neuroimmune systems that may influence alcohol drinking behaviors. Females are more vulnerable than males to the neurotoxic and negative consequences of chronic alcohol drinking, reflected by elevations of pro-inflammatory cytokines and inflammatory mediators. Differences in cytokine, microglial, astrocytic, genomic, and transcriptomic evidence suggest females are more reactive than males to neuroinflammatory changes after chronic alcohol exposure. The growing body of evidence supports that innate immune factors modulate synaptic transmission, providing a mechanistic framework to examine sex differences across neurocircuitry. Targeting neuroimmune signaling may be a viable strategy for treating AUD, but more research is needed to understand sex-specific differences in alcohol drinking and neuroimmune mechanisms.

An examination of the associations between depressive symptoms, perceived parental discipline, alcohol use, and drinking-related consequences during the first year of college: A moderated mediation model.

Depression is prevalent among adolescents and young adults and is associated with experiencing increased negative alcohol-related consequences; thus, it is imperative to identify malleable protective factors for alcohol risks in young adults experiencing elevated depressive symptoms. The current study longitudinally explored the effects of perceived parental alcohol-related discipline on the relationship between depressive symptoms, alcohol use, and negative drinking consequences during the transition into college. Incoming college students (N = 272, 63.2% female) completed web-based surveys before (July, T1) and after (October, T2) the transition into college and reported depressive symptoms, perceived alcohol-related discipline, alcohol use, and consequences of drinking experienced in the past 30 days. The moderated mediation model revealed that at above average perceptions of alcohol-related discipline, depressive symptoms were negatively associated with alcohol use, which in turn was associated with experiencing fewer negative consequences of drinking. The current study did not measure a diagnosis of major depressive disorder, and therefore our results may differ among clinical populations. In addition, we did not measure other parenting constructs shown to protect students with elevated levels of depressive symptoms from experiencing consequences (i.e., monitoring). The present findings suggest perceptions of parental alcohol-related discipline measured here (e.g., having a privilege taken away, being scolded or grounded) can be protective against alcohol risks among college students experiencing above average depressive symptoms. Parent-based alcohol interventions administered prior to matriculation should encourage parents of depressed students to clearly communicate consequences for drinking to their child.

Avoidance Coping as a Vulnerability Factor for Negative Drinking Consequences Among Injury Survivors Experiencing PTSD Symptoms:An Ecological Momentary Assessment Study

ABSTRACT The purpose of this study was to examine the dynamic relationships between daily PTSD symptom severity (PTSS), cognitive and behavioral avoidance coping, and negative drinking consequences following recent injury. Participants consisted of 36 injury survivors (Mage = 34.0, SD = 10.8; 75.0% male; 69.4% White) who completed thrice daily assessments of PTSS, avoidance coping, and negative drinking consequences for 7 days at 6-weeks post-injury. Although hypothesized relationships were not statistically significant in full models with covariates that included alcohol consumption, the confidence intervals associated with focal predictors provided support for predictions. Follow-up analyses without covariates indicated that on occasions when an injury survivor engaged in more avoidance coping and experienced higher levels of PTSS, negative drinking consequences increased by 9% (b = 0.02, SE = 0.01, p = .006). This interaction was primarily driven by cognitive avoidance coping (b = 0.03, SE = 0.01, p = .008). Routine screening of avoidance coping, PTSS, and alcohol consumption in the aftermath of recent injury might assist with identifying survivors at risk for negative drinking consequences. Interventions that address cognitive avoidance coping and drinking among survivors experiencing elevated PTSS may help to prevent the development of this comorbidity.

Impaired Decision-Making and Skin Conductance Responses Are Associated with Reward and Punishment Sensitivity in Individuals with Severe Alcohol Use Disorder

Introduction: Individuals with alcohol use disorder (AUD) have difficulties regulating alcohol consumption, despite adverse drinking-related consequences. This may be due to incapacity incorporating previous negative feedback from drinking, resulting in impaired decision-making. Methods: We assessed whether decision-making is impaired in participants with AUD related to severity of AUD, indexed by severe negative drinking consequences using the Drinkers Inventory of Consequences (DrInC) and reward and punishment sensitivity with the Behavioural Inhibition System Behavioural Activation System (BIS BAS) scales. 36 treatment-seeking alcohol-dependent participants completed the Iowa gambling task (IGT) with skin conductance responses (SCRs) measured continuously as an index of somatic autonomic arousal to evaluate impaired expectancy of negative outcomes. Results: Two-thirds of the sample showed behavioural impairment during the IGT, with greater AUD severity related to worse performance. BIS moderated IGT performance according to severity of AUD, with increased anticipatory SCRs for those with fewer reported DrInC severe consequences. Participants with more DrInC severe consequences showed IGT deficits and reduced SCRs regardless of BIS scores. BAS-Reward was associated with increased anticipatory SCRs to disadvantageous deck choices among those with lower AUD severity, while SCRs did not differ related to AUD severity for reward outcomes. Discussion: Effective decision-making in the IGT and adaptive somatic responses were moderated by punishment sensitivity contingent on severity of AUD in these drinkers, with impairments in expectancy to negative outcomes from risky choices, including reduced somatic responses, resulting in poor decision-making processes that may help explain impaired drinking and worse drinking-related consequences.

To Drink or Not to Drink: Is That the Question? Examining Correspondence and Predictive Validity of Morning Drinking Intentions for Young Adults' Drinking Behaviors and Consequences.

The Theory of Planned Behavior suggests that intentions are significant and proximal determinants of behavior. The purpose of this study was to test the predictive validity of drinking intentions for subsequent same-day drinking behaviors and negative consequences. Regularly drinking young adults (N = 222, 21-29years, 84% undergraduates) completed an ecological momentary assessment (EMA) protocol and wore an alcohol monitor for five consecutive 24-h periods spanning 6days (Wednesday-Monday). Each morning, participants reported their drinking intentions for the day and their previous day's alcohol consumption and the number of negative drinking consequences. Multilevel models showed that, at the within-person level, on days when people reported intending to drink, to get drunk, or to drink more than usual, they had higher odds of drinking, consumed more drinks, and had higher peak transdermal alcohol concentrations later that day. However, drinking occurred on 28% of days without drinking intentions, suggesting intentions were an imperfect signal for future drinking behavior. Morning drinking intentions also predicted experiencing more negative consequences, even after controlling for alcohol consumption. On average, young adults' morning-reported drinking-related intentions predicted increased odds of same-day drinking behavior and alcohol-related consequences. However, drinking frequently occurred on days participants did not intend to drink, suggesting that focusing only on drinking intention days will result in many missed prevention opportunities. Together, these results suggest the need for additional research to increase the predictive value of drinking intention assessments and for prevention interventions aimed at helping individuals follow through on their intentions not to drink.

Drinking Expectancies among Chinese Young Adults: A Qualitative Study from Hong Kong.

Background: Alcohol expectancies, i.e., the perceived consequences of drinking, have been reported to be important factor in predicting drinking behaviors. However, studies in the Asia region were largely limited to school-based samples. This study aimed to be the first to explore drinking expectancies among urban Chinese young adults. Methods: In 2020, eight focus group discussions were conducted with Hong Kong Chinese young adults aged 18–34 (n = 53). The participants included heavy drinkers, light drinkers, and non-drinkers from a wide range of occupations and educational backgrounds. Thematic analysis was conducted to uncover common alcohol expectancies. Results: Six themes emerged from this study. Four themes that were commonly reported in the literature were the negative consequences of drinking, social bonding, confidence enhancement, and tension reduction. The study also uncovered two culturally relevant alcohol expectancies: health benefits and business drinking expectancies. In contrast to Western samples, Chinese young adults did not report drinking expectancies related to cognitive enhancement or increased sexual interest. Conclusion: Alcohol harm reduction strategies will need to address the positive drinking expectancies uncovered in this study. Future policy discussions in this emerging alcohol market region should consider greater scrutiny of the role of alcohol marketing in the propagation of positive drinking expectancies.

Social Anxiety and Pre-Party Motives Are Associated With Alcohol-Related Negative Consequences During College Students' Most Recent Pre-Party Occasion.

Engaging in hazardous drinking behaviors, such as playing drinking games or pre-partying, is associated with excessive drinking and negative consequences among college students. Pre-partying or playing drinking games often occurs in anticipation of or during social situations. College students with elevated social anxiety who drink to cope with social anxiety symptoms in social settings may be especially vulnerable to drinking more heavily in these contexts and, in turn, experiencing more negative consequences. However, little is known about specific psychosocial factors that may inform the decision of socially anxious individuals to engage in hazardous drinking behaviors. The current study used cross-sectional data to test whether social anxiety symptoms and past-year pre-party motives were associated with (a) a greater likelihood of playing drinking games while pre-partying, (b) total alcohol consumption, and (c) consequences during students' most recent drinking occasion during which they pre-partied. Participants were 981 college students (63.5% women, 67.9% White, mean age = 20.1 years, SD = 1.3) who reported on their most recent pre-party drinking occasion. Greater social anxiety symptoms were related to higher past-year interpersonal enhancement and intimate pursuit motives, which in turn were associated with greater alcohol consumption and more negative consequences during the most recent pre-party event. Although preliminary, results highlight the importance of considering pre-party motives associated with social anxiety and negative drinking consequences among college students.

Does the relationship between alcohol retail environment and alcohol outcomes vary by depressive symptoms? Findings from a U.S. Survey of Black, Hispanic and White drinkers

AimsTo assess whether associations between alcohol availability and consumption, drinking to drunkenness, and negative drinking consequences vary among individuals with elevated depressive symptoms. Methods10,482 current drinkers in 2005–2015 National Alcohol Surveys (50.0% female; 74.4% White, 8.7% Black, 11.1% Hispanic). Elevated depressive symptoms was defined as having symptoms suggestive of major depressive disorder (above CES-D8/PHQ-2 cut-offs) versus no/sub-threshold symptoms (below cut-offs). Inverse probability of treatment weighted and covariate adjusted Poisson models with robust standard errors estimated associations of ZIP-code bar density and off-premise outlet density (locations/1,000 residents), elevated depressive symptoms, and their interaction with past-year volume consumed, monthly drinking to drunkenness, and negative drinking consequences. Models were then stratified by sex and race and ethnicity. ResultsOverall, 13.7% of respondents had elevated depressive symptoms. Regarding density, the only statistically significant association observed was between off-premise density and volume consumed (rate ratio = 1.3, 95% confidence interval = 1.0, 1.7). Elevated depressive symptoms were associated with higher volume consumed, prevalence of drinking to drunkenness, and prevalence of negative consequences when controlling for off-premise density or bar density. However, there was no evidence of interaction between symptoms and density in the full sample nor among subgroups. ConclusionThis study suggests that, while elevated depressive symptoms do not alter associations between alcohol availability and alcohol use and problems, they remain associated with these outcomes among past-year drinkers in a U.S. general population sample even when accounting for differential availability. Addressing depressive symptoms should be considered along with other policies to reduce population-level drinking and alcohol problems.

Ethnic/Racial Differences in Alcohol Use: Does Drinking Refusal Self-Efficacy Matter?

Introduction: College students—including those of Hispanic backgrounds—are at risk for hazardous drinking. Research has shown robust group differences between Hispanic and White individuals in alcohol use outcomes. The ability to resist alcohol consumption can be leveraged to reduce hazardous drinking; however, little research has examined Hispanic-White differences and whether drinking refusal self-efficacy accounts for group differences in hazardous drinking. Considering Hispanic individuals make up the largest ethnic/racial minority group in the United States, it is important to identify malleable psychological factors that prevent and reduce drinking problems. Method: Hispanic and White college students at two predominantly White institutions (N = 389; 58.6% women, Mage = 20.22) completed measures assessing drinking refusal self-efficacy, hazardous drinking, and negative drinking consequences. Results: Hispanic students reported lower levels of hazardous drinking, alcohol-related problems, and drinking refusal self-efficacy than White students. Drinking refusal self-efficacy was found to partially explain Hispanic-White differences in the levels of hazardous drinking and drinking-related problems. Specifically, drinking refusal self-efficacy was associated with alcohol use outcomes only among White students and not Hispanic students. Conclusion: The correspondence between drinking refusal self-efficacy and actual behaviors to turn down drinks, ethnic/racial distinctiveness in ratings of self-efficacy and cultural orientations, and situational contexts that surround drinking should be examined in future research.

Alcohol binge drinking decreases brain glucose metabolism and functional connectivity in adolescent rats.

Alcohol misuse represents a serious health concern, especially during adolescence, with approximately 18% of high school students engaging in binge drinking. Despite widespread misuse of alcohol, its effects on how the brain functions is not fully understood. This study utilized a binge drinking model in adolescent rats to examine effects on brain function as measured by brain glucose metabolism (BGluM). Following an injection of [18 FDG] fluro-2-deoxy-D-glucose, rats had voluntary access to either water or various concentrations of ethanol to obtain the following targeted doses: water (no ethanol), low dose ethanol (0.29 ± 0.03g/kg), moderate dose ethanol (0.98 ± 0.05), and high dose ethanol (2.19 ± 0.23g/kg). Rats were subsequently scanned using positron emission tomography. All three doses of ethanol were found to decrease BGluM in the restrosplenial cortex, visual cortex, jaw region of the somatosensory cortex, and cerebellum. For both the LD and MD ethanol dose, decreased BGluM was seen in the superior colliculi. The MD ethanol dose also decreased BGluM in the subiculum, frontal association area, as well as the primary motor cortex. Lastly, the HD ethanol dose decreased BGluM in the hippocampus, thalamus, raphe nucleus, inferior colliculus, and the primary motor cortex. Similar decreases in the hippocampus were also seen in the LD group. Taken together, these results highlight the negative consequences of acute binge drinking on BGluM in many regions of the brain involved in sensory, motor, and cognitive processes. Future studies are needed to assess the long-term effects of alcohol binge drinking on brain function as well as its cessation.

Likelihood of Posting Alcohol-Related Content on Social Networking Sites – Measurement Development and Initial Validation

Background: The vast majority of adolescents and young adults are active on social networking sites (SNSs). SNSs are influential, risk-conducive environments for alcohol use among adolescents and young adults. Specifically, posting or sharing alcohol-related content (ARC) is associated with higher levels of alcohol use. However, it is unknown if sharing different types of ARC associates differentially with alcohol use and consequences. Objective: The goal of the current project was to develop a measure of the likelihood of posting key types of ARC posted by adolescents and young adults and to examine their associations with SNS use patterns and actual alcohol-related behavior. Method: Participants were 15–20 years of age (n = 306; 46.7% male; 56.6% Caucasian/White; 27.0% Asian) who completed a battery of self-report measures. Results: Results from an exploratory factor analysis revealed four types of ARC: (1) self and friend consumption, (2) memes and viral photos, (3) status updates: others’ drinking and consequences, and (4) pictures: others’ drinking and consequences. Conclusions: Participants’ likelihood of posting self and Friend Consumption was significantly associated with heightened Snapchat use, typical drinks per week, peak drinking, and negative drinking consequences. Whereas youth appear to share more readily alcohol-related viral posts and memes, it seems that the sharing of ARC that is specifically related to the participants’ own use or friends’ use is salient concerning alcohol use and problems. Therefore, interventions might consider sending targeted prevention messages to individuals who share certain types of ARC which are more associated with problematic alcohol behaviors.

Effects of acute alcohol administration on working memory: a systematic review and meta-analysis.

Alcohol-induced executive function deficits may underlie associations between alcohol, self-regulation, and hazardous behaviors. Studies examining the effects of alcohol administration on working memory, an important executive functioning component, have produced mixed findings. Acute alcohol effects on working memory remain unclear. We aimed to conduct a systematic review and meta-analysis on the effects of acute alcohol administration on working memory outcomes in studies of healthy adults. We performed a systematic search of PubMed, MEDLINE, and PsycINFO from inception to June 2021. Studies were included if they met criteria, including healthy participants and administration of quantified alcohol doses against comparative controls. Data extracted included primary working memory outcomes, alcohol doses, and study characteristics. Study quality was assessed using an established validity measure. Working memory task type, alcohol dose, control condition type, and sex/gender composition were explored as moderators using mixed-effects models and meta-regressions. Thirty-two studies (1629 participants) provided sufficient data for 54 comparisons between alcohol and control conditions. Random-effects meta-analysis indicated that alcohol administration produced significant, small- to medium-sized working memory decrements (g [95% CI] = - 0.300 [- 0.390 to - 0.211], p < 0.001). Moderation analyses suggested that these effects differed as a function of task type, dose, control condition type, and sex/gender composition. The average quality rating across studies was good. Alcohol administration significantly impaired working memory performance, particularly when executive-related manipulation processes were involved. Future research is needed to investigate how alcohol-induced working memory impairments relate to compromised self-regulation, hazardous behavior, and negative drinking consequences.

Motives and Consequences of Alcohol Use in People With Social Anxiety Disorder: A Daily Diary Study

People with social anxiety disorder (SAD) are at increased risk for alcohol-related problems. Most research exploring social anxiety and alcohol use has examined negative drinking consequences, with less consideration of positive consequences—namely positive social experiences—that may reinforce alcohol use. In this daily diary study, we examined how adults diagnosed with SAD (N = 26) and a psychologically healthy control group (N = 28) experienced positive drinking consequences in naturally occurring drinking episodes during the study period. For 14 consecutive days, participants answered questions about alcohol use, motives for drinking, and positive consequences of drinking. On days when participants drank, those with SAD were more likely than healthy controls to perceive a reduction in anxiety, but the two groups did not differ in their likelihood of experiencing positive social drinking consequences. For both groups, on days when they were more motivated to drink to enhance social experiences (affiliation motives) or cope with distress (coping motives), they were more likely to obtain positive consequences from drinking. Compared to controls, participants with SAD endorsed stronger trait and daily coping motives (anxiety-coping, social anxiety-coping, and depression-coping). Results are discussed in the context of reinforcement mechanisms that may maintain social anxiety and alcohol use.

A National Study on Drinking Game Behaviors and Related Consequences Among NCAA Student-Athletes: Racial/Ethnic and Sex Differences

Research indicates that college student-athletes report more alcohol use and negative drinking consequences than non-student-athletes. One drinking practice that has been linked to heavy alcohol use and related consequences is playing drinking games. In the present study, we investigated which segment of the student-athlete population is most at risk for frequent drinking game participation, elevated alcohol consumption while playing drinking games, and negative drinking game consequences. We examined sex and racial/ethnic differences in behaviors and consequences associated with drinking games in a national sample of White, Hispanic, Black, and Asian American/Pacific Islander (AAPI) student-athletes. A total of 11,839 student-athletes (51.4% women) from 165 National Collegiate Athletic Association (NCAA) member institutions who endorsed lifetime participation in drinking games completed a confidential online survey. Hierarchical linear modeling revealed that being a White (vs. Black or Hispanic) student-athlete was associated with more frequent drinking game participation, and among AAPI and Black (but not White or Hispanic) student-athletes, men played drinking games more frequently than women. Being a Black (vs. White) student-athlete was associated with more drinking game consumption; no sex differences in drinking game consumption were found among Black student-athletes. Among White, AAPI, and Hispanic student-athletes, being a male student-athlete was associated with more drinking game consumption. Finally, female student-athletes had a higher likelihood of experiencing one or more negative consequences from drinking games than did male student-athletes. The association between drinking game participation and negative drinking game consequences was also stronger for women compared with men. Student-athletes are heterogeneous with regard to drinking game behaviors and related consequences. Knowing who is at greatest risk for drinking game participation and related outcomes is an important first step in developing targeted intervention approaches for student-athletes.

Soda Consumption Among Mexican Construction Workers in the Context of the Sugar-Sweetened Beverage Tax.

This study explored the psychosocial determinants of consumption of soda and other taxed sugar-sweetened beverages (SSBs) in Mexican construction workers (CWs) and whether consumption changed as a result of the 2014 SSB tax. We conducted a qualitative case study involving in-depth interviews and focus groups (FGs) with 30 Mexican CWs; supplemented with descriptions of the food and beverages consumed during lunch breaks. We used NVivo 10 to classify information according to the analysis categories, primarily informed by the Reasoned Action Approach (RAA). CWs reported not having changed their consumption of soda and other taxed SSBs as a result of the SSB tax, despite the price increase and "knowing" the potential negative consequences of soda drinking. The most important determinants of soda consumption are a deep-seated social norm of soda drinking and use of soda drinking as part of their professional identity; their likeness for soda; a wide availability of soda in their environments; and a low perceived behavioral control (because they thought themselves as addicted to it). Participants indicated that the best way for them not to consume soda would be if it were not available. These findings lend support for the tight regulation of the availability of SSBs. To have a meaningful impact on these consumers, the SSB tax may need to be much higher. Policy-level interventions should be coupled with interventions at the individual and community levels that aim at denormalizing soda consumption, create new meanings in relation to water consumption, and develop behavioral control to decrease soda consumption.

Mechanisms of change in drinking following an alcohol-related injury: A qualitative examination of the sentinel event effect

Background: Sentinel events are negative health-related events that trigger change in risky health behaviors. Despite its presumed major role in behavior change, the sentinel event effect has received little empirical attention. Through analysis of qualitative interviews, we explored how sentinel events trigger behavior change. Methods: Thematic analysis and concept mapping were used to develop a preliminary model of the sentinel event effect among a sample of 24 adult heavy drinking Mexican-origin men previously admitted to a hospital due to injury. The model was checked against cases that did versus did not report change in alcohol use following an alcohol-related negative event. Results: Findings suggest that sentinel events may arouse negative emotional reactions, encourage reflection on the negative consequences of drinking, and cause reevaluation of the severity and significance of drinking. These processes may increase motivation to change. Conclusions: Findings support the concept of the sentinel event as a natural intervention, and identifies potential social-cognitive and motivational mechanisms through which it influences change. Findings stand to inform research on mechanisms underlying brief intervention effects, and research that seeks to identify treatment targets.
