Predicting university undergraduates' binge-drinking behavior: a comparative test of the one- and two-component theories of planned behavior

Risk capacity and investment priority as moderators in the relationship between big-five personality factors and investment behavior: a conditional moderated moderated-mediation model

This paper aims to explore the relationship between big-five personality traits and investment behavior, particularly in the Indian context. Riding on the theory of planned behavior (TPB), we built a multi-layered moderated moderated-mediation model exploring the complex relationships between personality traits, investment attitude, and investment strategy. We collected data from 934 respondents from the southern part of India and analyzed using the Hayes (2018) PROCESS macros to test the hypotheses. The results indicate that (i) Personality traits (extraversion, emotional stability, conscientiousness, agreeableness, and openness to experience) are positively related to investment attitude and investment strategy, (ii) Investment attitude is positively related to investment strategy, (iii) Risk capacity moderates the relationship between personality traits and investment attitude, and (iv) Investment priority (second moderator) moderates the moderated relationship between personality traits, risk capacity (first moderator), and investment strategy mediated through investment attitude. Finally, the implications for behavioral finance and practicing managers are discussed.

To drink or not to drink: When drinking intentions predict alcohol consumption and consequences

OBJECTIVES

We examined daily associations between drinking intentions and drinking behaviour and tested past drinking behaviour and current social environment as potential moderators of the daily intention-behaviour association. We expected both more frequent past drinking and being in a high drinking environment to weaken the intention-behaviour association. We also tested intentionality as a moderator of the association between alcohol consumption and next-day negative outcomes, expecting that less intentional alcohol consumption would be related to greater stress and regret.

DESIGN

We tested these hypotheses using two separate micro-longitudinal studies of college students (Ns = 1,641, 540).

METHODS

In two samples, participants completed bursts of data collection in which they indicated their previous alcohol consumption and then completed 30 days of diary surveys in which they reported their alcohol consumption and social environment the previous evening and their levels of stress, regret, and drinking intentions that day.

RESULT

Consistent with our predictions, drinking intentions more strongly predicted drinking behaviour among individuals with less frequent past drinking behaviour, and, in Sample 1, drinking intentions more strongly predicted drinking behaviour among individuals in a low drinking environment. Contrary to hypotheses, results indicated that individuals with low drinking intentions were more likely to experience stress the next day, particularly if they consumed less alcohol. Greater consumption, however, was related to greater odds of experiencing regret, but this was stronger among individuals with higher drinking intentions.

CONCLUSIONS

Findings are discussed in terms of the complex interplay between intentions and both social environment and contextual factors with respect to predicting drinking level and related problems.

Know Your Safe Drinking Skills: Adaptation Strategies for the College Effect

Objective: The current study investigates the effects of an alcohol-prevention program delivered to college students in a formal classroom setting. Participants: The sample comprised 231 first-year college students who enrolled in a multisection “First Year Experience” course at a large northeastern university in the United States. Method: A naturalistic experiment was conducted, with a baseline evaluation at the beginning of the semester and a post-experiment evaluation near the end of the semester. Results: Social drinking attitudes, proximal drinking norm and the college effect are significant predictors of pre- and post-intervention episodic drinking frequency. The intervention reduced episodic drinking frequency as well as perceived distal and proximal drinking norms. It also increased drinking attitudes and did not change perceived efficacy or drinking-outcome expectancies. Conclusions: Practitioners could consider implementing a similar intervention to allow students to learn and practice safe drinking skills in the first year of their college life.

Application of the extended theory of planned behavior to understand Chinese students' intention to improve their oral health behaviors: a cross-sectional study

BACKGROUND

The present study aimed to develop and test an extended theory of planned behavior (TPB), which includes attitudes, subjective norms and perceived behavioral control, oral health knowledge, and past oral health behavior on the intention to improve oral health behaviors among primary school students in Shanghai, China.

METHODS

A school-based cross-sectional study was conducted with 414 students in the third-grade from 10 classes of Mingqiang Primary School located in Shanghai, China. Participants were recruited in October 2019. Data were collected through self-reported questionnaires, consisting of demographic characteristics, TPB variables, oral health knowledge and past oral health behaviors. Exploratory factor analysis was used to analyze TPB items. Pearson's correlation and hierarchical regression analyses were conducted to identify the associated factors of intention to improve oral health behaviors.

RESULTS

The study showed that among students in the third grade, attitudes, subjective norms, perceived behavioral control, and past oral health behaviors were associated with the intention to improve oral health behaviors. In the hierarchical regression analysis, age and sex were entered in Model 1 which significantly explained 3.00% of the variance (F = 6.26, p < 0.01). The addition of Model 2 variables of attitudes, perceived behavioral control, subjective norms, and oral health knowledge revealed that TPB variables explained 26.70% (F = 29.59, p < 0.01). For Model 3, the addition of past oral health behaviors accounted for a further 1% of variance, and the full model has accounted for 28.30% of the variance with the intention to improve oral health behaviors (F = 22.8, p < 0.01). Regression analyses supported that among the significant variables, perceived behavioral control had the largest beta weight, followed by subjective norms and past oral health behaviors.

CONCLUSION

The extended TPB model constructed in this study could be used to explain children's intentions to improve oral health behaviors. Children's oral health-related perceived behavioral control, subjective norms, and past oral health behaviors may serve as priority intervention targets in oral health promotion practices aimed at children.

Does an acute bout of moderate exercise reduce alcohol craving in university students?

Craving is considered to be a vital contributor to the onset and maintenance of alcohol misuse. However, there is little known about its potential moderators and there are few interventions that specifically target these cravings. Exercise generates multiple psychological and physiological effects that in theory may reduce craving, and therefore we hypothesised that a short exercise circuit may potentially alter reward circuits. Recent research centred around neuroimaging studies suggests that similar reward circuits in the brain stimulated through exercise are also found to be activated by commonly misused substances such as alcohol. Peripheral levels of dopamine, norepinephrine, and serotonin, as well as the release of endorphins that would otherwise be artificially stimulated using alcohol are hypothesised to increase via alternate substitution induced by exercise. Exercise would thus replace effects of alcohol use to a substantial extent, and therefore was theorised to decrease craving and subsequently reduce hazardous alcohol use. A university student sample who reported hazardous drinking levels participated in either an exercise, colouring (as an active control) or a passive control intervention, and self-reported alcohol craving, mood, anxiety, and positive and negative affect scores were assessed. The present study found that a short exercise circuit significantly reduced alcohol craving, whilst also eliciting beneficial effects on mood and anxiety. This knowledge will help aid the utilisation of exercise as a potential therapeutic tool to reduce alcohol craving, prevent hazardous alcohol use and develop a greater understanding of the mechanisms that underlie addictive behaviour.

Mothers Matter: Using Regression Tree Algorithms to Predict Adolescents' Sharing of Drunk References on Social Media

Exposure to online drinking on social media is associated with real-life alcohol consumption. Building on the Theory of planned behavior, the current study substantially adds to this line of research by identifying the predictors of sharing drunk references on social media. Based on a cross-sectional survey among 1639 adolescents with a mean age of 15 (59% female), this study compares and discusses multiple regression tree algorithms predicting the sharing of drunk references. More specifically, this paper compares the accuracy of classification and regression tree, bagging, random forest and extreme gradient boosting algorithms. The analysis indicates that four concepts are central to predicting adolescents' sharing of drunk references: (1) exposure to them on social media; (2) the perceived injunctive norms of the mother towards alcohol consumption; (3) the perceived descriptive norms of best friends towards alcohol consumption; and (4) willingness to drink alcohol. The most accurate results were obtained using extreme gradient boosting. This study provides theoretical, practical, and methodological conclusions. It shows that maternal norms toward alcohol consumption are a central predictor for sharing drunk references. Therefore, future media literacy interventions should take an ecological perspective. In addition, this analysis indicates that regression trees are an advantageous method in youth research, combining accurate predictions with straightforward interpretations.

Predicting binge drinking among university students: Application of integrated behavioral model

Background

Binge drinking is a pattern of harmful use of alcohol and it is defined as four drinks for women and five drinks for men in about 2 hours. This behavior causes public health problems like damaging different body organs.

Objective

To assess binge drinking and associated factors among Bahir Dar University students in Northwest Ethiopia.

Method

A cross sectional study was conducted in November 2017. Systematic sampling technique was used to select 422 participants. Structured questionnaire was used to collect data. Linear and Logistic regression models were used to predict the role of explanatory variables on behavioral intention and binge drinking, respectively. Independent variables with a p-value of <0.05 at 95% confidence interval were considered as statistically significant in the final model.

Result

A total of 413 students participated in this study and 33.4%(95% CI: 28.3–38.9) were engaged in binge drinking. Experiential attitude, instrumental attitude, and self-efficacy were found to be significant predictors of intention to binge drinking (p<0.05). Experiential attitude, environmental constraint, injunctive norm, and knowledge predictors were significantly associated with binge drinking (p<0.05).

Conclusion

Our study indicated that one-third of the students practiced binge drinking. This behavior was associated with experiential attitude, injunctive norm, environmental constraints, and knowledge factors. Additionally, experiential attitude, instrumental attitude, and self-efficacy constructs had explained behavioral intention. This implies focusing on the abovementioned determinant factors is imperative while designing intervention strategy.

Self-leadership and stress among college students: Examining the moderating role of coping skills†

Objective: Stress remains a major health concern among college students today. Consequently, research on student stress is imperative, from both an organizational and an individual perspective. This research study explores the moderating role of coping skills on the relationship between self-leadership and stress among college students. Participants: Data from 643 full-time undergraduate students attending a 4-year public university in the mid-Atlantic region were collected in February 2017 and analyzed using a moderated regression model. Results: The results indicate self-leadership practices do reduce student stress levels and that this relationship is moderated by student coping skills. Conclusion: The findings from this study deepen our understanding of how self-leadership practices may decrease student stress and showcases self-leadership as an effective tool for reducing college student stress.

A Test of the Theory of Planned Behavior in the Prediction of Alcohol-Induced Blackout Intention and Frequency

BACKGROUND

This study examined the theory of planned behavior (TPB) as an explanatory model for alcohol-induced blackouts among college students. Blackouts are periods of time wherein individuals continue to function and engage in their social environment but do not remember it as a result of consuming large quantities of alcohol. Social cognitive factors posited within TPB, such as perceived norms and personal attitudes toward alcohol consumption, are reliable predictors of alcohol use and related problems. However, research to date has not examined these theoretical antecedents as predictors of alcohol-induced blackout.

METHODS

College students with a history of blackout (N = 384) completed a baseline survey, and a subsample (N = 120) completed a 1-month follow-up survey. Negative binomial mediation models were used to evaluate intentions to blackout as a mediator of the norms, attitudes, and self-efficacy to avoid blackout-blackout frequency association at baseline and 1-month follow-up.

RESULTS

Norms, attitudes, and self-efficacy to avoid blackout all significantly predicted blackout intentions at baseline, which in turn predicted more frequent blackouts both at baseline and at 1-month follow-up. Notably, blackout attitudes demonstrated both direct and indirect associations with blackout frequency.

CONCLUSIONS

Prospective analyses provided partial support for the TPB, with only attitudes and intentions demonstrating prospective associations with actual blackout frequency. Given the particularly strong association between blackout attitudes and frequency of blackouts, attitudes may represent an important and novel target for prevention and intervention efforts.

Personality Traits and Stock Investment of Individuals

Behavioral finance has been widely applied in the financial realm from psychological perspectives focusing on herding and disposition effects. However, little research is devoted to the influences of personality traits on the stock investment intentions of individuals. This study extends the theory of planned behavior incorporating the big five personality taxonomies to investigate the effects of the personality traits of individual investors on stock investment intention. Utilizing partial least squares based on structural equation modeling techniques with a sample of 385 subjects, empirical results indicate that the stock investment intentions of individuals are significantly affected by subjective norm, attitude, and perceived behavioral control, and subjective norm significantly affects attitude. Individuals with open and agreeable personalities tend to have influences on subjective norm. Neurotic individuals tend to have negative attitudes toward stock investment. The perceived behavioral control of individuals regarding stock investment is influenced by the personality traits of agreeableness, extroversion, conscientiousness, and openness. Prior stock trading experiences significantly affect the relationships between attitude and stock investment intention, as well as on the linkages between extroversion and subjective norm, attitude, and perceived behavioral control. This study concludes with the discussion of the findings, with insights into theory and managerial implications.

Psychosocial Motivators for Moderate Drinking among Young Asian Flushers in Singapore

Asians are more susceptible to alcohol flush syndrome and its associated health risks because they are genetically predisposed towards it. Guided by the theory of planned behaviour, this research examined the psychosocial factors associated with moderate alcohol consumption, in order to inform the development of a health campaign targeting young Asian "flushers" in Singapore. We employed a mixed-method design comprising an online survey and focus group discussions. The survey results identified perceived behavioural control as the most salient belief associated with moderate drinking intentions, particularly for Asian flushers. Although Asian flushers had more positive attitudes towards, and perceived behavioural control about drinking in moderation, they were more likely to consider that their peers disapprove of such a practice, compared to non-flushers. Additionally, Asian flushers did not consider themselves as having a higher risk of long-term health effects from alcohol consumption than non-Flushers despite their actual high-risk status. Focus group findings suggest that young Asian flushers have poor knowledge of, and skills associated with moderate drinking, in addition to feeling self-imposed social pressure. The study findings provide practical insights into bridging the information gap on Asian flush and promoting Asian flushers' drinking in moderation.

A Causal Model of Binge Drinking Among University Students in Northern Thailand

Binge drinking, an extreme drinking pattern and the most common form of hazardous alcohol consumption among university students, has remained a public health concern with physical, psychological, academic, and social problems. Tracking multiple factors is needed to find ways to deal with such hazardous drinking patterns and their adverse consequences. In Thailand, the particular factors leading to binge drinking patterns among university students are still not recognized. Four hundred thirteen university students in Northern Thailand self-administered a Web-based survey about the causal factors. The survey was based on a hypothesized model from the Social Ecological Model and from empirical studies. There were four factors that were hypothesized to directly increase binge drinking behavior: attitudes toward drinking, peer influence, physical environments of drinking, and alcohol advertisements. However, there were another four factors that were hypothesized to directly decrease binge drinking behavior: drinking refusal self-efficacy, university alcohol regulations, alcohol public policies, and knowledge. Through testing of the hypothesized model by Structural Equation Modeling, the causal model of binge drinking among Thai university students revealed "binge drinking refusal self-efficacy" (β = -.22, p < .001) and "peer influence" (β = -.14, p < .05) as significant negative factors and "physical environments" (β = .18, p < .001) as a positive predictor regarding binge drinking. The study shows how healthcare providers may be able to lessen binge drinking by designing effective prevention programs centering on an intrapersonal factor (binge drinking refusal self-efficacy), an interpersonal factor (peer influence), and a community factor (physical environments).

The Roles of Prevention Messages, Risk Perception, and Benefit Perception in Predicting Binge Drinking among College Students

To account for the effect of prevention-message exposure on binge drinking among college students, I hypothesized a conceptual model outlining potential mechanisms including perceived probability of negative consequences (PPNC), perceived severity of negative consequences (PSNC), perceived probability of positive consequences (PPPC), and perceived beneficiality of positive consequences (PBPC) from binge drinking, based on the two-step process model. I conducted an online survey at a public university in the US (N = 278). Findings suggested only PBPC was significantly related to binge drinking and the relationship was positive; prevention-message exposure was not directly associated with binge drinking, but was positively associated with PPNC, PSNC, PPPC, and PBPC; none of the mediational paths was significant; higher risk perception (interaction between PPNC and PSNC) was significantly related to less binge drinking, while benefit perception (interaction between PPPC and PBPC) was not predictive of binge drinking. Implications of findings were discussed.

Predictors and psychological pathways for binge drinking among South African men

OBJECTIVE

To develop targeted interventions for high-risk drinkers among South African men, we assessed whether sociodemographic factors and history of childhood sexual abuse predicted binge drinking at six-month follow-up assessment and their psychological pathways according to the extended Theory of Reasoned Action (TRA).

DESIGN

Survey responses with a sample of 1181 South African men from randomly selected neighbourhoods in Eastern Cape Province were collected at baseline and six-month follow-up. Multiple logistic regression analysis examined the baseline predictors of binge drinking. Serial multiple mediation analysis examined the psychological pathways.

MAIN OUTCOME MEASUREMENTS

Binge drinking at six-month follow-up.

RESULTS

Age (OR = 1.03, 95% CI: 1.01, 1.05), religious participation (OR = .73, CI: .65, .82) and history of childhood sexual abuse (OR = 1.82, CI: 1.32, 2.51) were significant predictors of binge drinking. Predictions of religious participation and history of childhood sexual abuse were partially mediated through attitude, subjective norm, descriptive norm and intention to binge drinking.

CONCLUSION

South African men with childhood sexual abuse experience and low religious participation were at higher risk for binge drinking. The extended TRA model explains the associations of these factors to binge drinking and can contribute to the design and evaluation of interventions.

Meta-Analysis of the Reasoned Action Approach (RAA) to Understanding Health Behaviors

Background

Reasoned action approach (RAA) includes subcomponents of attitude (experiential/instrumental), perceived norm (injunctive/descriptive), and perceived behavioral control (capacity/autonomy) to predict intention and behavior.

Purpose

To provide a meta-analysis of the RAA for health behaviors focusing on comparing the pairs of RAA subcomponents and differences between health protection and health-risk behaviors.

Methods

The present research reports a meta-analysis of correlational tests of RAA subcomponents, examination of moderators, and combined effects of subcomponents on intention and behavior. Regressions were used to predict intention and behavior based on data from studies measuring all variables.

Results

Capacity and experiential attitude had large, and other constructs had small-medium-sized correlations with intention; all constructs except autonomy were significant independent predictors of intention in regressions. Intention, capacity, and experiential attitude had medium-large, and other constructs had small-medium-sized correlations with behavior; intention, capacity, experiential attitude, and descriptive norm were significant independent predictors of behavior in regressions.

Conclusions

The RAA subcomponents have utility in predicting and understanding health behaviors.

Predicting heavy episodic drinking using an extended temporal self-regulation theory

INTRODUCTION

Alcohol consumption contributes significantly to the global burden from disease and injury, and specific patterns of heavy episodic drinking contribute uniquely to this burden. Temporal self-regulation theory and the dual-process model describe similar theoretical constructs that might predict heavy episodic drinking. The aims of this study were to test the utility of temporal self-regulation theory in predicting heavy episodic drinking, and examine whether the theoretical relationships suggested by the dual-process model significantly extend temporal self-regulation theory.

METHODS

This was a predictive study with 149 Australian adults. Measures were questionnaires (self-report habit index, cues to action scale, purpose-made intention questionnaire, timeline follow-back questionnaire) and executive function tasks (Stroop, Tower of London, operation span). Participants completed measures of theoretical constructs at baseline and reported their alcohol consumption two weeks later. Data were analysed using hierarchical multiple linear regression.

RESULTS

Temporal self-regulation theory significantly predicted heavy episodic drinking (R²=48.0-54.8%, p<0.001) and the hypothesised extension significantly improved the prediction of heavy episodic drinking frequency (ΔR²=4.5%, p=0.001) but not peak consumption (ΔR²=1.4%, p=0.181). Intention and behavioural prepotency directly predicted heavy episodic drinking (p<0.01). Planning ability moderated the intention-behaviour relationship and inhibitory control moderated the behavioural prepotency-behaviour relationship (p<0.05).

CONCLUSIONS

Both temporal self-regulation theory and the extended temporal self-regulation theory provide good prediction of heavy episodic drinking. Intention, behavioural prepotency, planning ability and inhibitory control may be good targets for interventions designed to decrease heavy episodic drinking.

Visual attention to alcohol cues and responsible drinking statements within alcohol advertisements and public health campaigns: Relationships with drinking intentions and alcohol consumption in the laboratory

Both alcohol advertising and public health campaigns increase alcohol consumption in the short term, and this may be attributable to attentional capture by alcohol-related cues in both types of media. The present studies investigated the association between (a) visual attention to alcohol cues and responsible drinking statements in alcohol advertising and public health campaigns, and (b) next-week drinking intentions (Study 1) and drinking behavior in the lab (Study 2). In Study 1, 90 male participants viewed 1 of 3 TV alcohol adverts (conventional advert; advert that emphasized responsible drinking; or public health campaign; between-subjects manipulation) while their visual attention to alcohol cues and responsible drinking statements was recorded, before reporting their drinking intentions. Study 2 used a within-subjects design in which 62 participants (27% male) viewed alcohol and soda advertisements while their attention to alcohol/soda cues and responsible drinking statements was recorded, before completing a bogus taste test with different alcoholic and nonalcoholic drinks. In both studies, alcohol cues attracted more attention than responsible drinking statements, except when viewing a public health TV campaign. Attention to responsible drinking statements was not associated with intentions to drink alcohol over the next week (Study 1) or alcohol consumption in the lab (Study 2). However, attention to alcohol portrayal cues within alcohol advertisements was associated with ad lib alcohol consumption in Study 2, although attention to other types of alcohol cues (brand logos, glassware, and packaging) was not associated. Future studies should investigate how responsible drinking statements might be improved to attract more attention.

A Cross-sectional Analysis of Motivation and Decision Making in Referrals to Lifestyle Interventions by Primary Care General Practitioners: A Call for Guidance

AIM

To explore (1) general practitioners' (GPs') motivations to refer to lifestyle interventions and to investigate the association between GPs' own lifestyle behaviors and their referral behavior and (2) patient indicators in the decision-making process of the GPs' referral to lifestyle interventions.

METHOD

A cross-sectional study was conducted among 99 Dutch primary care GPs. Their motivation to refer was assessed by beliefs regarding lifestyle interventions. GPs' referral behaviors were assessed-considering referral and self-reported actual referral-as well as their own lifestyle behaviors (physical activity, dieting, being overweight). Decision making regarding referring patients to lifestyle interventions was assessed by imposed patient indicators, spontaneously suggested decisive patient indicators, and case-based referring (vignettes).

RESULTS

A substantial group of GPs was not motivated for referral to lifestyle interventions. GPs' referral behavior was significantly associated with their perceived subjective norm, behavioral control, and their own physical activity and diet. Most important, patient indicators in referral to lifestyle interventions were somatic indicators and patients' motivation for lifestyle interventions.

CONCLUSIONS

GPs' motivation and referral behavior might be improved by providing them with tailored resources about evidence-based lifestyle interventions, with support from allied health professionals and with official guidelines for a more objective and systematic screening of patients.

The associations among prior drinking consequences, subjective evaluations, and subsequent alcohol outcomes

Although the many positive and negative psychosocial consequences of alcohol use are well documented, evidence of the association between prior drinking consequences and subsequent alcohol-related outcomes is mixed. Social learning theory highlights that cognitive appraisals of prior drinking consequences play a crucial intermediate role in the relation of prior drinking consequences with subsequent alcohol-related outcomes. This prospective study was designed to test the mediating effects of subjective evaluations (i.e., perceived valence and controllability) in the association of prior drinking consequences with change in binge drinking and drinking consequences over time. Participants were 171 college students (69% female, 74% White, M age = 18.95 years, SD = 1.35) who completed 2 online surveys, with an average interval of 68 days (SD = 10.22) between assessments. Path analyses of the data did not support mediational effects of perceived valence or controllability of prior drinking consequences on subsequent alcohol-related outcomes. Specifically, greater frequency of negative consequences was associated with lower perceived valence and controllability, and greater frequency of positive consequences was associated with lower perceived controllability of the experienced consequences. However, perceptions of valence and controllability were not in turn associated with subsequent binge drinking and drinking consequences. Instead, greater frequency of positive consequences was directly associated with greater subsequent frequency of binge drinking. Findings highlight the importance of prior positive consequences in the escalation of binge drinking over a short period of time, although this relation may not be accounted for by perceptions of valence and controllability of the prior drinking consequences.

Alcohol consumers' attention to warning labels and brand information on alcohol packaging: Findings from cross-sectional and experimental studies

Background

Alcohol warning labels have a limited effect on drinking behavior, potentially because people devote minimal attention to them. We report findings from two studies in which we measured the extent to which alcohol consumers attend to warning labels on alcohol packaging, and aimed to identify if increased attention to warning labels is associated with motivation to change drinking behavior.

Methods

Study 1 (N = 60) was an exploratory cross-sectional study in which we used eye-tracking to measure visual attention to brand and health information on alcohol and soda containers. In study 2 (N = 120) we manipulated motivation to reduce drinking using an alcohol brief intervention (vs control intervention) and measured heavy drinkers’ attention to branding and warning labels with the same eye-tracking paradigm as in study 1. Then, in a separate task we experimentally manipulated attention by drawing a brightly colored border around health (or brand) information before measuring participants’ self-reported drinking intentions for the subsequent week.

Results

Study 1 showed that participants paid minimal attention to warning labels (7% of viewing time). Participants who were motivated to reduce drinking paid less attention to alcohol branding and alcohol warning labels. Results from study 2 showed that the alcohol brief intervention decreased attention to branding compared to the control condition, but it did not affect attention to warning labels. Furthermore, the experimental manipulation of attention to health or brand information did not influence drinking intentions for the subsequent week.

Conclusions

Alcohol consumers allocate minimal attention to warning labels on alcohol packaging and even if their attention is directed to these warning labels, this has no impact on their drinking intentions. The lack of attention to warning labels, even among people who actively want to cut down, suggests that there is room for improvement in the content of health warnings on alcohol packaging.

Models of health behaviour predict intention to use long acting reversible contraception use

The aim of this study was to investigate women’s intention to use long-acting reversible contraception using two established models of health behaviour: the theory of planned behaviour and the health belief model. A questionnaire was completed by a convenience sample of 128 women attending a community sexual health clinic. The independent variables were constructs of theory of planned behaviour (attitude, subjective norm and perceived behavioural control) and health belief model (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, health motivation and cues to action). The dependent variable was intention to use long-acting reversible contraception. The theory of planned behaviour and the health belief model accounted for 75% of the variance in intention to use. Perceived behavioural control, perceived barriers and health motivation predict the use of long-acting reversible contraception. Public health information for women considering using long-acting reversible contraception should be based around addressing the perceived barriers and promoting long-acting reversible contraception as a reliable contraceptive method.

Lost in translation: a focus group study of parents' and adolescents' interpretations of underage drinking and parental supply

Background

Reductions in underage drinking will only come about from changes in the social and cultural environment. Despite decades of messages discouraging parental supply, parents perceive social norms supportive of allowing children to consume alcohol in ‘safe’ environments.

Methods

Twelve focus groups conducted in a regional community in NSW, Australia; four with parents of teenagers (n = 27; 70 % female) and eight with adolescents (n = 47; 55 % female). Participants were recruited using local media. Groups explored knowledge and attitudes and around alcohol consumption by, and parental supply of alcohol to, underage teenagers; and discussed materials from previous campaigns targeting adolescents and parents.

Results

Parents and adolescents perceived teen drinking to be a common behaviour within the community, but applied moral judgements to these behaviours. Younger adolescents expressed more negative views of teen drinkers and parents who supply alcohol than older adolescents. Adolescents and parents perceived those who ‘provide alcohol’ (other families) as bad parents, and those who ‘teach responsible drinking’ (themselves) as good people. Both groups expressed a preference for high-fear, victim-blaming messages that targeted ‘those people’ whose behaviours are problematic.

Conclusions

In developing and testing interventions to address underage drinking, it is essential to ensure the target audience perceive themselves to be the target audience. If we do not have a shared understanding of underage ‘drinking’ and parental ‘provision’, such messages will continue to be perceived by parents who are trying to do the ‘right’ thing as targeting a different behaviour and tacitly supporting their decision to provide their children with alcohol.

The impact of social cognitive and personality factors on teachers' reported inclusive behaviour

BACKGROUND

Inclusive education of children with intellectual disabilities (ID) is intended to maximize their educational experience within the mainstream school setting. While policy mandates inclusion, it is classroom teachers' behaviours that determine its success.

AIMS

This study provided a novel application of the theory of planned behaviour (TPB) in this setting. It examined the effect of TPB variables and personality on reported inclusive teaching behaviours for learners with ID.

SAMPLE

The sample comprised 145 primary school teachers (85% female) from mainstream schools across Scotland.

METHOD

Participants completed a TPB questionnaire assessing attitudes (instrumental and affective), subjective norms (injunctive and descriptive norms), perceptions of control (self-efficacy and controllability), and behavioural intentions towards using inclusive strategies. The Big Five Personality Index, measuring extraversion, conscientiousness, openness, neuroticism, and agreeableness, was also completed. Teaching practices were reported 2 weeks later.

RESULTS

Instrumental attitudes, descriptive norm, self-efficacy, and neuroticism predicted teachers' intentions to use inclusive strategies. Further, conscientiousness had indirect effects on intentions through TPB variables. These intentions, however, did not predict reported behaviour expected by TPB. Instead, self-efficacy was the only significant predictor of reported behaviour.

CONCLUSIONS

This study demonstrates the application of TPB to an educational setting and contributes to the understanding of teachers' reported use of inclusive strategies for children with ID.

Heavy Drinking and Social and Health Factors in University Students from 24 Low, Middle Income and Emerging Economy Countries

The aim of this study was to investigate heavy drinking and social and health correlates in university students in low, middle income and emerging economy countries. Using anonymous questionnaires, data were collected in a cross-sectional survey of 17,590 undergraduate university students (mean age 20.8, SD 2.9) from 25 universities in 24 countries across Asia, Africa and the Americas. Overall, 71.6 % were non-drinkers, 17.1 % moderate and 11.3 % heavy alcohol drinkers (14.2 % in men and 9.2 % in women) in the past 2 weeks. In a multivariate logistic regression analysis, older age, poorer family background, living in a higher income country, weak beliefs in the importance of limiting alcohol use, higher country per capita alcohol consumption, other substance use (tobacco and illicit drug use), and poor life satisfaction was associated with heavy drinking. Addressing health beliefs and co-occurring addictive behaviors may be crucial in the prevention of heavy drinking in this population.

Checking Behaviours, Prospective Memory and Executive Functions

Explanations implicating memory in the causes and severity of checking symptoms have focused primarily on retrospective memory, and relatively little attention has been paid to prospective memory. Limited research has examined the relationship between prospective memory and executive functions. We assessed whether impairments in prospective memory and executive function predict checking symptoms in a sample of 106 adults. Checking symptoms were assessed using the Padua Inventory Washington State University Revision (PI-WSUR). All participants completed the prospective memory questionnaire (PMQ) and four computerised executive function tasks from the CANTAB, measuring inhibition, planning, attention set-shifting and working memory. Prospective memory and inhibition predicted checking symptom severity. Importantly, there were no correlations between internally cued prospective memory and inhibition or between prospective memory aiding strategies and inhibition. These variables appear to have an independent role in checking. The current findings highlight prospective memory and inhibition as key contributors to the checking symptom profile and provide the first evidence that these cognitive processes may independently contribute to checking symptoms. These findings have implications for a model in which memory performance is thought to be secondary to impairments in executive functions.

Facebook Displays as Predictors of Binge Drinking: From the Virtual to the Visceral

Given the prevalence of social media, a nascent but important area of research is the effect of social media posting on one's own self. It is possible that an individual's social media posts may have predictive capacity, especially in relation to health behavior. Researchers have long utilized concepts from the Theory of Reasoned Action (TRA) to predict health behaviors. The theory does not account for social media, which may influence or predict health behaviors. The purpose of this study was to test a model including Facebook alcohol displays and constructs from the TRA to predict binge drinking. Incoming college freshmen from two schools (312 participants between the ages of 18 and 19) were interviewed prior to (T1) and one year into college (T2), and their Facebook profiles were evaluated for displayed alcohol content. Path modeling was used to evaluate direct and indirect paths predicting binge drinking. Path analysis suggested that Facebook alcohol displays at T1 directly predict binge drinking at T2, while alcohol attitude both directly and indirectly predicts binge drinking. Based on these results, a preliminary model of social media presentation and action is discussed.

Predicting Binge Drinking in College Students: Rational Beliefs, Stress, or Loneliness?

We proposed a conceptual model to predict binge-drinking behavior among college students, based on the theory of planned behavior and the stress-coping hypothesis. A two-wave online survey was conducted with predictors and drinking behavior measured separately over 2 weeks' time. In the Wave 1 survey, 279 students at a public university in the United States answered questions assessing key predictors and individual characteristics. In the Wave 2 survey, 179 participants returned and reported their drinking behavior over 2 weeks' time. After conducting a negative binomial regression, we found that more favorable attitude toward drinking and less perceived control of drinking at Wave 1 were associated with more binge drinking at Wave 2; subjective norm at Wave 1 was not a significant predictor of binge drinking at Wave 2; students with higher stress at Wave 1 engaged in more binge drinking at Wave 2, but those with higher loneliness did not. Implications of findings are discussed.

Testing the bi-dimensional effects of attitudes on behavioural intentions and subsequent behaviour

Attitudes are typically treated as unidimensional predictors of both behavioural intentions and subsequent behaviour. On the basis of previous research showing that attitudes comprise two independent, positive and negative dimensions, we hypothesized that attitudes would be bi-dimensional predictors of both behavioural intentions and subsequent behaviour. We focused on health-risk behaviours. We therefore also hypothesized that the positive dimension of attitude (evaluations of positive behavioural outcomes) would better predict both behavioural intentions and subsequent behaviour than would the negative dimension, consistent with the positivity bias/offset principle. In Study 1 (cross sectional design), N = 109 university students completed questionnaire measures of their intentions to binge-drink and the positive and negative dimensions of attitude. Consistent with the hypotheses, both attitude dimensions independently predicted behavioural intentions and the positive dimension was a significantly better predictor than was the negative dimension. The same pattern of findings emerged in Study 2 (cross sectional design; N = 186 university students) when we predicted intentions to binge-drink, smoke and consume a high-fat diet. Similarly, in Study 3 (prospective design; N = 1,232 speed limit offenders), both the positive and negative dimensions of attitude predicted subsequent (6-month post-baseline) speeding behaviour on two different road types and the positive dimension was the better predictor. The implications for understanding the motivation of behaviour and the development of behaviour-change interventions are discussed.

How well does the theory of planned behaviour predict alcohol consumption? A systematic review and meta-analysis

This study aimed to quantify correlations between theory of planned behaviour (TPB) variables and (i) intentions to consume alcohol and (ii) alcohol consumption. Systematic literature searches identified 40 eligible studies that were meta-analysed. Three moderator analyses were conducted: pattern of consumption, gender of participants and age of participants. Across studies, intentions had the strongest relationship with attitudes (r₊ = .62), followed by subjective norms (r₊ = .47) and perceived behavioural control (PBC; r₊ = .31). Self-efficacy (SE) had a stronger relationship with intentions (r₊ = .48) compared with perceived control (PC; r₊ = −.10). Intention had the strongest relationship with alcohol consumption (r₊ = .54), followed by SE (r₊ = .41). In contrast, PBC and PC had negative relationships with alcohol consumption (r₊ = −.05 and −.13, respectively). All moderators affected TPB relationships. Patterns of consumption with clear definitions had stronger TPB relations, females reported stronger attitude–intention relations than males, and adults reported stronger attitude–intention and SE–intention relations than adolescents. Recommendations for future research include targeting attitudes and intentions in interventions to reduce alcohol consumption, using clear definitions of alcohol consumption in TPB items to improve prediction and assessing SE when investigating risk behaviours.

Beyond inhibition: a dual-process perspective to renew the exploration of binge drinking

Binge drinking is a widespread alcohol-consumption pattern in youth and is linked to cognitive consequences, mostly for executive functions. However, other crucial factors remain less explored in binge drinking and notably the emotional-automatic processes. Dual-process model postulates that addictive disorders are not only due to impaired reflective system (involved in deliberate behaviors), but rather to an imbalance between under-activated reflective system and over-activated affective-automatic one (involved in impulsive behaviors). This proposal has been confirmed in alcohol-dependence, but has not been tested in binge drinking. The observation of comparable impairments in binge drinking and alcohol-dependence led to the “continuum hypothesis,” suggesting similar deficits across different alcohol-related disorders. In this perspective, applying the dual-process model to binge drinking might renew the understanding of this continuum hypothesis. A three-axes research agenda will be proposed, exploring: (1) the affective-automatic system in binge drinking; (2) the systems’ interactions and imbalance in binge drinking; (3) the evolution of this imbalance in the transition between binge drinking and alcohol-dependence.

Changing how I feel about the food: experimentally manipulated affective associations with fruits change fruit choice behaviors

Fewer than half of Americans meet current recommendations for fruit and vegetable intake. The behavioral affective associations model posits that feelings and emotions associated with a behavior are a proximal influence on decision making. Cross-sectional evidence supports the model and suggests that affective associations predict fruit and vegetable consumption. The purpose of this study was to test whether a causal relation exists between affective associations about fruits and future fruit consumption behavior, as measured by a snack selection task. Following a baseline assessment of cognitive and affective variables, participants' (N = 161) affective associations about fruits were experimentally manipulated with an implicit priming paradigm. Images of fruits were repeatedly paired with positive, negative, or neutral affective stimuli. The key outcome measure was a behavioral choice task in which participants chose between fruit and a granola bar. Participants in the positive prime condition were three times more likely than those in the negative condition to select a piece of fruit over the granola bar alternative in the snack selection task. They were also twice as likely as those in the neutral condition to select fruit. There were no changes in self-reported affective associations or cognitive beliefs. These findings provide further evidence of the implicit and direct influence of affective associations on behavior, suggesting the need to both incorporate the role of affect in health decision making models, as well as the potential utility of intervention strategies targeting affective associations with health-related behaviors.

Evidence that changes in social cognitions predict changes in self-reported driver behavior: Causal analyses of two-wave panel data

Previous research on the theory of planned behavior (TPB) is characterized by cross-sectional tests of the model's proposed causal relationships. In the absence of effective experimental techniques for changing the TPB's cognitive antecedents, the present research aimed to provide a stronger non-experimental test of the model, using causal analyses of two-wave panel data. Two studies of driver behavior were conducted in which naturally occurring within-participant changes in TPB constructs were measured over time, and used to predict corresponding within-participant changes in both intentions and behavior. A two-wave panel design was used in both studies. Study 1 had a one-month gap between baseline and follow-up. At both waves, a convenience sample comprising predominantly university students (N=135) completed questionnaire measures of all TPB cognitions and behavior (compliance with speed limits in urban areas). Cross-lagged multiple regressions and bootstrapping procedures for testing multiple mediators supported all of the relationships proposed by the TPB. These findings were extended in study 2 using a large, non-student sample of speed limit offenders (N=1149), a six-month gap between baseline and follow-up, and a larger number of cognitive antecedents. Participants completed postal questionnaires at both waves to measure all cognitions proposed by the two-component TPB, along with moral norm, anticipated regret, self-identity and speeding on urban roads, country roads, and fast dual carriageways or motorways. Changes in instrumental and affective attitude, descriptive norm, self-efficacy, moral norm, anticipated regret and self-identity predicted changes in intention to speed. Changes in intention and self-efficacy predicted behavior-change. Injunctive norm and perceived controllability did not predict intention or behavior-change. Additionally, direct (unhypothesized) relationships with behavior were found for affective attitude, descriptive norm and anticipated regret. The implications of the findings for theory and the development of effective behavior-change interventions are discussed.
