Drinking to Cope is Uniquely Associated with Less Specific and Bleaker Future Goal Generation in Young Hazardous Drinkers
Groups with mental health and/or substance use problems generate less detailed descriptions of their future goals. As substance use to cope with negative affect is common to both groups, this characteristic might be uniquely associated with less specific goal descriptions. To test this prediction, 229 past year hazardous drinking undergraduates aged 18–25 years wrote about three positive future life goals in an open-ended survey, before reporting their internalizing (anxiety and depression) symptoms, alcohol dependence severity and motivations for drinking: coping, conformity, enhancement and social. Future goal descriptions were experimenter-rated for detail specificity, and participant-self-rated for positivity, vividness, achievability, and importance. Effort in goal writing was indexed by time spent writing and total word count. Multiple regression analyses revealed that drinking to cope was uniquely associated with the production of less detailed goals, and lower self-rated positivity and vividness of goals (achievability and importance were also marginally lower), over and above internalizing symptoms, alcohol dependence severity, drinking for conformity, enhancement and social motives, age, and gender. However, drinking to cope was not uniquely associated with reduced effort in writing goals: time spent and word count. In sum, drinking to cope with negative affect is a unique characteristic predicting the generation of less detailed and bleaker (less positive and vivid) future goals, and this is not due to lower effort in reporting. Future goal generation may play a role in the aetiology of comorbidity of mental health and substance use problems, and therapeutic targeting of goal generation might benefit both conditions.

Abstract:
Evidence for an alcohol-related "harm paradox" in individuals with internalizing disorders: Test and replication in two independent community samples.
BACKGROUND: Internalizing (anxiety and mood) disorders (INTD) commonly co-occur (are "comorbid") with alcohol use disorder (AUD). The literature suggests that excessive alcohol use aimed at coping with INTD symptoms is, at best, a partial explanation for the high comorbidity rates observed. We hypothesized that individuals with INTD experience greater susceptibility to developing AUD symptoms due to the partially shared neurobiological dysfunctions underlying both conditions. We probe this hypothesis by testing the prediction that, after accounting for the volume of alcohol intake, individuals with INTD experience higher levels of alcohol-related symptoms. METHODS: Data from the National Epidemiological Survey on Alcohol-Related Conditions (NESARC) Wave 3 were used for the primary analyses, and NESARC Wave 1 data were used for independent replication analyses. Individuals who reported any alcohol use in the prior year were categorized as: (1) never having had an INTD diagnosis ("INTD-Never"); (2) having a remitted INTD diagnosis only ("INTD-Remitted"); or (3) having current INTD diagnosis ("INTD-Current"). Between-group contrasts of alcohol-related symptoms controlled for total alcohol intake (past year), drinking pattern (e.g. binging) and variables previously shown to mark exaggerated AUD symptoms relative to drinking amount (e.g. SES, gender, and family history). RESULTS: with all covariates in the model, individuals in the INTD-Current group and the INTD-Remitted group reported significantly greater alcohol-related symptoms than those in the INTD-Never group but did not themselves differ in level of alcohol-related symptoms. These results were replicated in the NESARC 1 dataset. CONCLUSIONS: Individuals with INTD experience more alcohol-related symptoms than those who drink at the same level. While considering other explanations, we argue that this "harm paradox" is best explained by the view that INTD confers a neurobiologically mediated susceptibility to the development of AUD symptoms.

Abstract:
The unique role of drinking to cope in the aetiology of and intervention for alcohol use problems
Negative affect has a profound motivational effect on alcohol use problems, but understanding of the underlying mechanisms is incomplete. In this thesis, evidence is reported which supports the claim that the tendency to use alcohol to cope with negative affect is a unique mediator of the risk that both external (socioeconomic deprivation, environmental adversity) and internal adversity (internalising problems, lack of adaptive coping strategies) confer for alcohol use problems. Furthermore, the direct effect of drinking to cope (DTC) on alcohol problems was invariant across genders and countries and could not be explained by level of alcohol consumption, suggesting that another mechanism underpins the universal risk conferred by DTC. A novel finding is that DTC was uniquely associated with bleak expectations regarding future goals, characterised by less positive, vivid, achievable, important and specific goals. The implication is that bleak prospects of hazardous drinkers who drink to cope could play a role in the risk of alcohol problems, and interventions which improve their prospects could potentially be effective in mitigating alcohol use problems. To test this proposal, three small randomised controlled intervention studies investigated whether providing alternative adaptive coping strategies for negative affect would mitigate proxies for alcohol problems. Study one found that a brief training of mindful breath counting attenuated noise stress-induced alcohol-seeking in a lab setting in a general undergraduate sample. The second and third study trained alternative adaptive coping strategies that emphasised visualising future adaptive responses to negative affect in hazardous drinking undergraduates who drink to cope, and these studies demonstrated preliminary effectiveness in improving alcohol-related outcomes at two-week and four-week follow-up in the UK and South African samples respectively. These findings suggest that building resilience to negative affect by training engagement with positive future strategies may mitigate some of the risk of alcohol problems in young adult hazardous drinkers who drink to cope with negative affect.

Abstract:
Reinforcer pathology of internet-related behaviors among college students: Data from six countries.
Research has demonstrated that repeated engagement in low-effort behaviors that are associated with immediate reward, such as Internet use, can result in a pathological reinforcement process in which the behavior is increasingly selected over other activities due, in part, to a low availability of alternative activities and to a strong preference for immediate rather than delayed rewards (delay discounting). However, this reinforcer pathology model has not been generalized to other Internet-related behaviors, such as online gaming or smartphone use. Given the widespread availability of these technologies, it is also important to examine whether reinforcer pathology of Internet-related behaviors is culturally universal or culture-specific. The current study examines relations between behavioral economic constructs (Internet demand, delay discounting, and alternative reinforcement) and Internet-related addictive behaviors (harmful Internet use, smartphone use, online gaming, and Internet sexual behavior) in a cross-sectional sample of college students (N = 1,406) from six different countries (Argentina, Australia, India, Malaysia, the United Kingdom, and the United States). Using structural equation modeling, Internet demand was associated with harmful Internet use, smartphone use, and online gaming; delay discounting was associated with harmful smartphone use; and alternative reinforcement was associated with harmful Internet and smartphone use. The models were partially invariant across countries. However, mean levels of behavioral economic variables differed across countries, country-level gross domestic product, person-level income, and sex at birth. Results support behavioral economic theory and highlight the importance of considering both individual and country-level sociocultural contextual factors in models for understanding harmful engagement with Internet-related behaviors.

Risk Pathways Contributing to the Alcohol Harm Paradox: Socioeconomic Deprivation Confers Susceptibility to Alcohol Dependence via Greater Exposure to Aversive Experience, Internalizing Symptoms and Drinking to Cope
Socioeconomic deprivation is associated with greater alcohol problems despite lower alcohol consumption, but the mechanisms underpinning this alcohol harm paradox remain obscure. Fragmented published evidence collectively supports a multistage causal risk pathway wherein socioeconomic deprivation increases the probability of exposure to aversive experience, which promotes internalizing symptoms (depression and anxiety), which promotes drinking alcohol to cope with negative affect, which in turn accelerates the transition from alcohol use to dependence. To evaluate this proposed risk pathway, 219 hazardous drinkers from an undergraduate population completed questionnaires assessing these constructs in a single, cross sectional, online survey. Partial correlation coefficients revealed that each variable showed the strongest unique association with the next variable in the proposed multistage model, when adjusting for the other variables. Bootstrapped serial mediation analysis revealed that the indirect pathway linking all the variables in the proposed serial order was significant, while all other permutations were non-significant. Network centrality analysis corroborated the serial order of this indirect path. Finally, risk ratios estimated by categorizing the variables suggested that socioeconomic deprivation increased the risk of aversive experience by 32%, which increased the risk of internalizing symptoms by 180%, which increased the risk of drinking to cope by 64%, which increased susceptibility to alcohol dependence by 59%. These preliminary findings need to be corroborated by future research, nevertheless, they call for prevention strategies founded on social justice and the minimization of aversive experience in socially deprived individuals to mitigate mental health problems, maladaptive coping and addiction.

The direct effect of drinking to cope on alcohol problems is not mediated by alcohol consumption: Invariance across gender and countries.
BACKGROUND: Drinking to cope with negative affect confers a direct risk of alcohol problems independently of greater alcohol consumption (i.e. confers susceptibility to the alcohol harm paradox). However, it remains unclear whether this risk is common across gender and countries. METHODS: the current study applied path analysis to two cross-sectional samples of 18-25-year-old undergraduate hazardous drinking students recruited from the UK (Study 1; N = 873) and internationally (Study 2; N = 4064 recruited in Argentina, Canada, South Africa, Spain, Uruguay, USA, and England). The Drinking Motives Questionnaire (DMQ) measured drinking to cope with negative affect and drinking to enhance positive affect (i.e. enhancement motives). The Alcohol Use Disorders Identification Test (AUDIT) measured alcohol consumption and problems. RESULTS: in both studies, drinking to cope with negative affect had a direct effect on alcohol problems (S1: β = 0.259, SE = 0.031, p

Abstract:
Brief Negative Affect Focused Functional Imagery Training Abolishes Stress-Induced Alcohol Choice in Hazardous Student Drinkers
Introduction. Imagery-based stress management therapies are effective at reducing alcohol use. To explore the therapeutic mechanism, the current study tested whether brief functional imagery training linked to personal negative affect drinking triggers would attenuate sensitivity to noise stress-induced alcohol seeking behaviour in a laboratory model. Methods. Participants were UK-based hazardous student drinkers (N = 61, 80.3% women, aged 18–25) who reported drinking to cope with negative affect. Participants in the active intervention group (n = 31) were briefly trained to respond to personal negative drinking triggers by retrieving an adaptive strategy to mitigate negative affect, whereas participants in the control group (n = 30) received risk information about binge drinking at university. The relative value of alcohol was then measured by preference to view alcohol versus food pictures in two-alternative choice trials, before (baseline) and during noise stress induction. Results. There was a significant two-way interaction

Abstract:
Brief Online Negative Affect Focused Functional Imagery Training Improves 2-Week Drinking Outcomes in Hazardous Student Drinkers: a Pilot Randomised Controlled Trial
Abstract
. Background
. Negative affect plays an important role in motivating problematic alcohol use. Consequently, training imagery-based adaptive responses to negative affect could reduce problematic alcohol use. The current study tested whether personalised online functional imagery training (FIT) to utilise positive mental imagery in response to negative affect would improve drinking outcomes in hazardous negative affect drinking students.
.
. Method
. Participants were 52 hazardous student drinkers who drink to cope with negative affect. Participants in the active group (n = 24) were trained online over 2 weeks to respond to personalised negative drinking triggers by retrieving a personalised adaptive strategy they might use to mitigate negative affect, whereas participants in the control group (n = 28) received standard risk information about binge drinking at university. Measures of daily drinking quantity, drinking motives, self-efficacy and use of protective behavioural strategies were obtained at baseline and 2 weeks follow-up.
.
. Results
. There were three significant interactions between group and time in a per-protocol analysis: the active intervention group showed increased self-efficacy of control over negative affect drinking and control over alcohol consumption and decreased social drinking motives from baseline to 2-week follow-up, relative to the control intervention group. There were no effects on drinking frequency.
.
. Conclusion
. These findings provide initial evidence that online training to respond to negative affect drinking triggers by retrieving mental imagery of adaptive strategies can improve drinking-related outcomes in hazardous, student, negative affect drinkers. The findings support the utility of FIT interventions for substance use.
