Towards a Comprehensive Typology of Knowledge for Social Work and Alcohol

This article presents a theoretical model of knowledge acquisition by social workers with regards to alcohol, which formed the propositional element of a recently awarded doctoral thesis submission. It begins by briefly contextualising the relationship between alcohol and social work, the profession's response to the increasing sense of alcohol-related issues in workloads and calls for more effective intervention responses. In considering how this is often reflected in demands for social workers to receive more education about alcohol, it critically examines existing considerations of possible typologies of knowledge for social work, before encapsulating them within a model focusing on alcohol. The model suggests that any such typology is likely to be composed of multiple sources, including both codified and non-codified elements. It concludes by considerations of some of the implications for research approaches that could be used to gain a better understanding of these knowledge frameworks. In doing so it proposes that it is through these alternative considerations that more holistic understandings of social work knowledge will be established. Discussion of the implications of working within more inclusive knowledge frameworks, for social work education, policy, practice and research, are contained throughout the article.     

A meta-analysis of effectiveness of E-interventions to reduce alcohol consumption in college and university students.

Objective: To evaluate the effectiveness and moderators of E-Interventions versus assessment only (AO) controls in the reduction of alcoholic drinks per week (DPW) in university students.

Study design and methods: Cochrane library, CINAEL, ERIC, MEDLINE, PsycINFO, PubMed, and Web of Science were searched up to June 2017. Studies were included if they were: an RCT, assessed the effectiveness of E-Interventions at reducing DPW, and employed university/college students. 23 studies (N = 7,614) were included and quality was assessed using the JADAD scale.

Results: Weighted mean effect sizes were calculated using random-effects models. These showed a small, significant effect of E-Interventions at reducing the number of alcoholic DPW. Moderator analysis found a significant advantage for web-based personalised feedback interventions compared to other E-Interventions.

Conclusions: E-Interventions show a small, significant effect at reducing mean alcoholic DPW. Personalised feedback E-Interventions showed the strongest effect.     

What “likes” have got to do with it: Exposure to peers' alcohol-related posts and perceptions of injunctive drinking norms

Objective: Examine 1) whether observed social reinforcements (i.e., “likes”) received by peers' alcohol-related social media posts are related to first-year college students' perceptions of peer approval for risky drinking behaviors; and 2) whether associations are moderated by students' alcohol use status. Participants: First-year university students (N = 296) completed an online survey in September, 2014. Method: Participants reported their own alcohol use, friends' alcohol use, perceptions of the typical student's approval for risky drinking, and ranked 10 types of social media posts in terms of the relative numbers of “likes” received when posted by peers. Results: Observed social reinforcement (i.e., “likes”) for peers' alcohol-related posts predicted perceptions of peer approval for risky drinking behaviors among non-drinking students, but not drinking students. Conclusions: For first-year college students who have not yet initiated drinking, observing peers' alcohol-related posts to receive abundant “likes” may increase perceptions of peer approval for risky drinking.     

Alcohol outlets,social disorganization,and robberies: Accounting for neighborhood characteristics and alcohol outlet types

We estimated spatially lagged regression and spatial regime models to determine if the variation in total, on-premise, and off-premise alcohol outlet¹ density is related to robbery density, while controlling for direct and moderating effects of social disorganization.² Results suggest that the relationship between alcohol outlet density and robbery density is sensitive to the measurement of social disorganization levels. Total alcohol outlet density and off-premise alcohol outlet density were significantly associated with robbery density when social disorganization variables were included separately in the models. However, when social disorganization levels were captured as a four item index, only the association between off-premise alcohol outlets and robbery density remained significant. More work is warranted in identifying the role of off-premise alcohol outlets and their characteristics in robbery incidents.     

Alcohol-Influenced Nonverbal Behaviors During Discussions About a Relationship Problem

We examined the effect of alcohol intoxication on the display of nonverbal behaviors during discussions with dating partners about a relationship problem. Forty-four heterosexual dyads engaged in a 7-min conversation about a hypothetical infidelity. Males were randomly assigned to drinking condition (sober or .08 g/dl) and their behaviors were coded for behavioral expressivity, verbal expressivity, positive affect, and anxiety at 30 s and 3 min into the interaction. A series of 2 (drinking condition) × 2 (time) repeated measures analyses indicated that as time passed, drinkers nonverbally conveyed more agitation and less positivity, and consequently less pro-relational behavior. Further, drinkers showed more behavioral variability over time compared to their sober counterparts. The implications of these results for understanding alcohol-influenced communication in close relationships are discussed.

Factors Affecting Alcohol Purchase Decisions and Expenditures: A Sample Selection Analysis by Ethnicity in Malaysia

Heckman’s sample selection model was applied to data from the Malaysian Household Expenditure Survey 2004/2005 to examine the factors influencing the likelihood of purchasing and the amount spent on alcohol in Malaysia. Results of the marginal effects suggest that while socio-demographic factors are important determinants of household purchase decisions and expenditure levels on alcohol in Malaysia, the effects vary across ethnic groups. Specifically, although education had a significant but modest impact in reducing the probability of alcohol purchases and expenditure levels among ethnic Chinese households, this effect was not evident among the ethnic Indians and other races. While increasing household size lowered the likelihood of purchasing alcohol and its expenditure levels for all ethnic groups, the reinforcing effects of both income and gender were relevant only for ethnic Chinese and Indian households. Last, urban Indian households were less likely to purchase alcohol and spend less compared to rural Indian households.

The role of age and setting in adolescents’ first drinking experience for predicting college problem drinking

Objective: The purpose of this study was to determine the reliability of longitudinally reporting age at first drink (AFD), and to test AFD and setting of first drink (SFD) as predictors of collegiate problem drinking. Participants: 338 first-year college students were interviewed multiple times during their first academic year, from May 2011 through August 2012. Methods: AFD, SFD, and problem drinking were measured using the Alcohol Use Disorders Identification Test (AUDIT) during the first year of college. Bivariate analysis and parsimonious multivariate linear regression model were conducted. Results: 62% of respondents were inconsistent in reporting AFD over time. Social SFD was the strongest independent predictor for higher AUDIT scores (b = 4.74, 95% confidence interval; 1.91, 7.57; p = .002). Conclusions: Findings suggest caution should be used in relying upon using AFD as a sole predictor of problem drinking. SFD may be a complementary measure to identify students at high risk of collegiate problem drinking.     

Comparative analysis of emergency department patients lost to follow-up after computerized alcohol screening and brief intervention

Many studies have evaluated the effectiveness of alcohol screening and brief intervention (SBI) but most of them have reported substantial loss to follow-up without investigating the characteristics of those lost to follow-up. We examined the association between Alcohol Use Disorders Identification Test (AUDIT) scores, readiness-to-change scores and the demographic factors with lost to follow-up. This retrospective study compared demographic characteristics, AUDIT and readiness-to-change scores for 190 lost to follow-up patients to 221 completed follow-up patients who participated in SBI in the Emergency Department between June 2006 and May 2007. Comparing the association between baseline characteristics and completed follow-up rate, those 30–39, 40–49 and 50 years and older had 0.46 (95% CI 0.32–0.91), 0.49 (95% CI 0.29–0.90) and 0.58 (95%CI 0.22–0.79) lower odds of completing follow-up, respectively, in comparison to those 18–29 years of age. The loss to follow-up group reported more negative consequences of alcohol and binge drinking than the completed follow-up group (p = 0.04). Using logistic regression, patients who experienced more negative effects of alcohol had 0.87 lower odds of completing follow-up (95% CI 0.79–0.96). The patients lost to follow-up in this study were significantly different in age and alcohol drinking habits compared to those completed follow-ups. It is important to consider differential loss to follow-up in assessing the validity and generalizability of intervention studies. This could help in tailoring methods of approaching patients based on target population characteristics.     

Appetitive and impulsive: Examining alcohol use via the motivational and self-control systems

This study examines how trait differences in the appetitive and defensive systems and how automatic, impulsive and deliberate, reflective responses to alcohol cues predict overall alcohol use. By utilizing a measure of trait motivational activation and measures of implicit and explicit attitudes toward alcohol that indicate the self-control system – impulsive vs. reflective – that determines behavior, this research demonstrates that higher trait appetitive system activity, ASA, and positive impulsive/implicit alcohol attitudes independently predict alcohol use, while trait defensive system activation, DSA, and explicit attitudes toward alcohol did not independently predict use.
