The unique role of attachment dimensions and peer drinking in adolescent alcohol use

A review of factors influencing drinking behaviours in young Australian adults using a behavioural framework approach

ISSUES

Young adults (aged 18-24 years) are more likely to binge drink than any other age group in Australia. These behaviours expose young adults to possible adverse events, with potential for acute harms.

APPROACH

A behavioural framework (capability, opportunity, motivation-behaviour [COM-B model]) was used to explore factors that influence the drinking behaviours of young Australian adults. Potential studies were identified by searching four online data bases. Content pertaining to factors moderating young adults' alcohol consumption behaviours (either increasing or decreasing alcohol consumption) in an Australian population was extracted. Factors were then categorised/mapped into the six sub-components of the COM-B model. A narrative synthesis/discussion was subsequently undertaken.

KEY FINDINGS

Factors increasing or reducing alcohol consumption behaviours were identified across all components of the COM-B model. Overall, alcohol consumption behaviours appear strongly influenced by physical and social opportunities, and young adults have reflective and automatic motivations (i.e., habitual processes, emotional responding and analytical decisional making that directs behaviour) to consume alcohol with purpose and/or reason.

IMPLICATIONS AND CONCLUSION

The use of a behavioural framework (e.g., the COM-B model) facilitates an integrated understanding of factors influencing alcohol consumption behaviours. Future harm minimisation strategies need to consider the interrelated, contemporary factors underpinning a young adult's decision to consume alcohol within the context of modern Australian society.

Individual Variables Involved in Perceived Pressure for Adolescent Drinking

Adolescence is a stage when individuals are especially vulnerable to the influence of their peer group, which could lead to the development of problematic behavior, such as drinking alcohol, due to perceived pressure. The objective of this study was to analyze the role of self-esteem, impulsivity, anxiety sensitivity and expectations for use under perceived pressure to drink alcohol among young people.

METHODS

The sample was made up of 1287 high school students aged 14 to 18, with a mean age of 15.11. The Bayes factor and mediation models were estimated to evaluate the data.

RESULTS

The results showed the existence of a positive relationship of impulsivity, anxiety sensitivity and expectations for use with perceived pressure. However, this relationship was negative with self-esteem and perception of pressure to drink alcohol. Furthermore, the model results showed that self-esteem mediates the relationship between physical, cognitive and social anxiety sensitivity and positive expectations with perceived pressure to drink alcohol in adolescence.

CONCLUSIONS

Given the strong need for affiliation during youth, it is hard to control grouping and peer influence on drinking behavior. However, knowledge of the role of individual variables, such as those described here, in perceived pressure could improve the prevention and intervention of such behaviors.
