Testing an Online, Theory-Based Intervention to Reduce Pre-drinking Alcohol Consumption and Alcohol-Related Harm in Undergraduates: a Randomized Controlled Trial

Application of Self-Determination Theory to Substance Use and Its Treatment: A Scoping Review of the Literature

Background: Self-determination theory (SDT) may provide important insights for understanding substance misuse and treatment outcomes. However, to date, the literature applying SDT to substance use and its treatment is varied and difficult to integrate. Methods: The authors searched psycINFO and PubMed on October 26th, 2021 to identify articles applying SDT to substance use and its treatment. Eligible studies were published in peer-reviewed articles in English, on adult populations (18+), and explicitly applied SDT to the context of substance use or its treatment. Results were categorized as studies applying SDT in non-treatment or treatment settings and were synthesized within these categories by substance(s) of focus, primary outcome(s), component(s) of SDT utilized, and relevant findings. Results: The search revealed 38 articles applying SDT in non-treatment (k = 16) and treatment (k = 22) settings. Causality orientations and the basic psychological needs were the most frequently studied components of SDT. Studies that applied SDT in non-treatment settings placed a greater emphasis on causality orientations, whereas treatment studies more frequently targeted or measured basic psychological needs. Conclusions: SDT constructs consistently predicted both substance misuse and treatment outcomes in a theoretically consistent manner, however, several important gaps remain and opportunities for future research are discussed.

What makes an action plan "100% me"? Think aloud interviews about CVD prevention tools for varying health literacy needs

ISSUE ADDRESSED

Health behaviour change can be difficult to maintain. Action plans can address this issue, however, there has been little qualitative research to understand how to optimise action plan interventions. This study explored how people engage with a specific type of action plan intervention, the "volitional help sheet," in a cardiovascular disease (CVD) prevention context.

METHODS

Twenty adults in the target age for CVD risk assessment (45 to 74 years) with varying health literacy participated in interviews and created an action plan to change their behaviour. Transcripts were analysed using framework analysis.

RESULTS

Participants described how engagement with plans was related to how personally relevant the target behaviour and the options within the plan were. Also important was participants visualising themselves enacting the plan when deciding which option to choose. Amongst participants who already engaged in a target behaviour, some did not perceive the plan was useful; others perceived the plan as a helpful prompt or a formalisation of existing plans. For some, the barriers to behaviour change were out of the scope of an action plan, highlighting the need for alternative supports.

CONCLUSION

This study provides qualitative insights into unanticipated ways that people with varying health literacy use action plans, providing new guidance for future developers. SO WHAT?: Not all action plans are created equal. Careful selection of behavioural targets and plan options and encouraging users to imagine the plan may enhance user engagement. Alternative behaviour change strategies should be available if key barriers cannot be addressed by the plan.

Women who pre-game: A study of stress and alcohol use in female collegiate predrinkers

Introduction: This study examined the relationship between stress and pre-gaming (i.e., drinking prior to going out to an event) in female college students. Methods: Thirty-four female college students were grouped as pre-gamers or non-pre-gamers based on self-reported drinking patterns. They completed surveys about alcohol use and mental health and provided a set of salivary cortisol samples upon waking, 30 min later, and at 10am on the same day. Results: Pre-gamers and non-pre-gamers did not differ on demographics or psychosocial variables. Pre-gamers reported riskier drinking overall and had greater endorsement of social, coping, and enhancement drinking motives. Pre-gamers also had lower cortisol levels 30 min after waking and exhibited attenuated CAR. Conclusions: Female collegiate pre-gamers may differ from their peers not only in terms of alcohol consumption and drinking motives, but also on attenuated CAR, a physiological biomarker associated with stress dysregulation and vulnerability to addictive behaviors.

Prologue to the special issue on predrinking and drinking game behaviors among adolescents and young adults in the United States and across the globe: Definitions and overview of prevalence rates

Predrinking and drinking games (DGs) are common risky drinking practices among adolescents and young adults in many different countries around the world. However, most studies on these behaviors have been conducted with university student samples in a limited number of countries. Despite the risks of negative alcohol-related consequences associated with predrinking and DGs, these activities are quite prevalent among young people. In this prologue, we provide definitions for predrinking and DGs and an extensive overview of the known prevalence rates of predrinking and DGs among young people around the world. This special issue addresses known gaps in the literature by including articles which (a) use differing methodologies to examine predrinking or DGs behavior, (b) consider psychosocial and contextual factors that influence these behaviors, and (c) examine young people's perceptions of alcohol policies and interventions. Taken together this Special Issue offers an international view on how and why young people around the world engage in these risky drinking practices, and potential ways to address these behaviors.

Analysis of participant-rated feasibility and acceptability of an online, theory-based pre-drinking behavioural intervention

To date, few interventions have been developed to target pre-drinking specifically. An online, theory-based intervention by Caudwell et al. (2018) showed reductions in pre-drinking alcohol consumption and alcohol-related harm, albeit independent of the intervention component/s used. Information about feasibility and acceptability of pre-drinking interventions may therefore be an important point of focus in refining and developing effective interventions. The present manuscript investigates how participants (N = 117) in Caudwell et al. (2018) rated the intervention in terms of feasibility and acceptability. A feasibility and acceptability measure was factor analysed and investigated in relation to participant scores on theory-based measures (e.g., attitude, goal self-concordance), as well as demographic and alcohol consumption variables measured at baseline. Results indicate participants with higher scores on theory-based measures related to behaviour change and goal self-concordance at baseline rated the intervention more positively at follow-up. The findings indicate future intervention research should consider stages of change, with broader alcohol policy and public health strategy focused on changing attitudes toward pre-drinking, which remains a popular health-risk behaviour.

Do Dimensional Measures of Mental Health Symptoms Predict Level of Alcohol Involvement in the General Population?

Background: There is a limited understanding of what specific mental health symptoms are associated to alcohol involvement. It is important to understand how the severity of different mental health dimensions may differ, and distinguish between, levels of alcohol involvement. Objectives: (a) explore for differences in severity of mental health symptoms between those with lower, and moderate/high alcohol involvement, (b) assess the degree to which mental health dimensions can distinguish between those with lower, and moderate/high alcohol involvement, and (c) examine what mental health dimensions are related to the highest risk of moderate/high alcohol involvement. Results: 400 participants representative of the general population in the USA were recruited online through Prolific and completed the Alcohol, Smoking and Substance Involvement Screening Test and Brief Symptom Inventory. Each of the nine mental health symptom dimensions significantly differed between lower and moderate/high alcohol involvement, with the moderate/high alcohol involvement group reporting greater severity symptoms. The nine symptom dimensions in combination also significantly distinguished lower and moderate/high alcohol involvement, however only somatization offered unique predictive utility. Lastly, global distress was also able to significantly distinguish the alcohol involvement groups, albeit to a lesser accuracy compared to the collection of individual symptom dimensions. Conclusions: These findings suggest that overall mental health distress may be important to understanding alcohol involvement, however individual symptom dimensions can add further explanatory variance. In particular, somatic symptoms may offer unique utility in understanding the relationship between mental health and alcohol involvement.

The effect of forming implementation intentions on alcohol consumption: A systematic review and meta-analysis

ISSUES

Meta-analysis was used to estimate the effect of forming implementation intentions (i.e., if-then plans) on weekly alcohol consumption and heavy episodic drinking (HED). Sample type, mode of delivery, intervention format and timeframe were tested as moderator variables.

APPROACH

Cochrane, EThOS, Google Scholar, PsychArticles, PubMed and Web of Science were searched for relevant publications to 31 March 2021. Random-effects meta-analysis was used to estimate the effect size difference (d) between individuals forming versus not forming implementation intentions on weekly consumption and HED.

KEY FINDINGS

Sixteen studies were included in meta-analyses. The effect size difference for forming implementation intentions on weekly alcohol consumption was d₊  = -0.14 confidence interval (CI) [-0.24; -0.03]. Moderator analyses highlighted stronger effects for: (i) community (d₊  = -0.38, CI [-0.58; -0.18]) versus university (d₊  = -0.04, CI [-0.13; 0.05]) samples; (ii) paper (d₊  = -0.26, CI [-0.43; -0.09]) versus online (d₊  = -0.04, CI [-0.14; 0.06]) mode of delivery; and (iii) volitional help sheet (d₊  = -0.34, CI [-0.60; -0.07]) versus implementation intention format (d₊  = -0.07, CI [-0.16; 0.02]). In addition, effects diminished over time (B = 0.02, SE = 0.01, CI [0.03; 0.01]). Forming implementation intentions had a null effect on HED, d₊  = -0.01 CI [-0.10; 0.08].

IMPLICATIONS

Forming implementation intentions reduces weekly consumption but has no effect on HED.

CONCLUSION

This review identifies boundary conditions on the effectiveness of implementation intentions to reduce alcohol consumption. Future research should focus on increasing the effectiveness of online-delivered interventions and integrating implementation intention and motivational interventions.

Health behavior interventions for university students measuring mental health outcomes: A scoping review

Introduction

Many university students have poor mental health, and co-occurring health risk behaviors. Targeting health behavior change in this population may improve mental health outcomes. This scoping review describes the extent and range of randomized controlled trials (RCT) evaluating interventions targeting health risk behaviors and measuring a mental health outcome, among university students.

Methods

Six electronic databases were searched for RCTs published until the 18^th May 2021. Eligible RCTs included university students, evaluated interventions that promoted health behavior change (i.e., dietary intake, physical activity, sedentary behavior, alcohol and drug use, smoking, and sleep), and measured a mental health-related outcome.

Results

Fifty-nine RCTs met the inclusion criteria that were published from 2000 to 2021, and over half (n = 33) were conducted in the United States. Interventions evaluated within the RCTs (n = 92) predominantly targeted changes to dietary intake (n = 41 interventions), physical activity (n = 39), or alcohol intake (n = 35). Most interventions targeted one (n = 51) or two (n = 27) health behaviors only. Included RCTs considered mental ill health outcomes (n = 24), psychological wellbeing outcomes (n = 20), or both (n = 15).

Discussion

This scoping review identified a moderate volume of experimental research investigating the impact of health behavior interventions on university students' mental health. There is scope for further research examining health behavior interventions targeting university students, particularly interventions taking a multi-behavioral approach.

Intervenciones para reducir el consumo de alcohol en jóvenes universitarios

Introducción: el consumo nocivo y excesivo de alcohol en los jóvenes ha sido reconocido como un comportamiento de riesgo significativo, por tanto, reducir el consumo y los problemas asociados es una prioridad entre los investigadores, educadores y profesionales de la salud que trabajan con esta población. Objetivo: examinar la evidencia actual sobre las intervenciones para reducir el consumo de alcohol de jóvenes universitarios. Método: se utilizó la metodología propuesta por Toronto y Remington. Para la evaluación y selección de los artículos cuantitativos se empleó el Instrumento de Criterios de Elegibilidad para la Selección de los Artículos de Investigación (ICrESAI) y para la evaluación de los ensayos clínicos aleatorizados se empleó la lista de verificación Estándares Consolidados de Informes de Ensayos (Consort). Resultados: se encontraron trece artículos, diez de ellos ensayos clínicos aleatorizados, dos cuantitativos longitudinales y un ensayo factorial. Conclusión: se encontró una gran variedad de diseños y propuestas de intervención, dentro de las cuales se demostró que las intervenciones breves entregadas de manera digital, tanto en la web, como en teléfonos inteligentes, son efectivas para reducir el consumo de riesgo de alcohol entre los jóvenes.

A mobile-based pregaming drinking prevention intervention for college students: study protocol for a randomized controlled trial

BACKGROUND

Pregaming is a high-drink context popular among college students that often leads to elevated blood alcohol levels and negative consequences. Over 15 years of research studies have demonstrated that pregaming represents one of the riskiest known behaviors among college students, yet no pregaming-specific interventions have been developed to help prevent this behavior. General brief interventions for students do not reduce pregaming behavior and may not be appropriate, as they do not help students develop skills unique to the pregaming context that could help them drink less. We developed a brief, mobile-based intervention that is proposed to prevent heavy drinking during pregaming for college students, with the ultimate goal that behavioral reductions in this risky practice will ultimately affect global drinking and prevent consequences.

METHODS/DESIGN

The intervention, Pregaming Awareness in College Environments (PACE), was developed by combining two innovations to facilitate behavior change: (1) a mobile-based application that increases accessibility, is easy and engaging to use, and broadens the reach of the intervention content and (2) personalized pregaming-specific intervention content with harm reduction and cognitive behavioral skills proven to be mechanisms preventing and reducing heavy drinking among college students. After a develop and beta-test phase, we propose to test the efficacy of PACE in a preliminary randomized controlled trial with 500 college students who pregame at least once per week. Pregaming, general drinking, and alcohol-related consequences outcomes will be examined in the immediate (2 weeks post-intervention) and short-terms (six and 14-week post-intervention). We will also evaluate moderator effects for age, sex, and heaviness of drinking to allow for more refined information for a planned larger test of the intervention to follow this initial trial of PACE.

DISCUSSION

This pregaming intervention clinical trial, if found to be efficacious, will culminate with an easily-disseminated mobile-based intervention for college student drinkers. It has the potential to reach millions of college students, perhaps as a clinical tool used by college counseling centers as an adjunct to formal care or as a preventive tool for first-year students or other high-risk groups on campus.

Online interventions for people hospitalized for deliberate self-harm and problematic alcohol use: Lessons learned from the iiAIM trial

Deliberate self-harm and suicide affect all age groups, sexes, and regions, and their prevention is a global health priority. Acute alcohol misuse and chronic alcohol misuse are strong, modifiable risk factors, and Internet interventions aiming to reduce alcohol misuse and comorbid mental health problems (e.g., depression) are a promising and effective treatment modality. The research team aimed to evaluate the feasibility and effectiveness of an Internet-based comorbidity intervention primarily aiming to reduce alcohol consumption, and secondarily to reduce readmission for deliberate self-harm and improve psychological outcomes among people hospitalized for deliberate self-harm who also engage in problematic alcohol use. However, due to several barriers to recruitment, the trial could not be completed and was discontinued. The authors present a "Lessons Learned" discussion and describe the Internet Intervention for Alcohol Improvement (iiAIM) trial, discuss the key barriers experienced by the research team, and recommend potential solutions that may help future trials in this area.

A systematic review of alcohol education programs for young people: do these programs change behavior?

Numerous education programs have addressed young peoples' alcohol use. To date, no peer-reviewed publication has evaluated the effectiveness of such programs delivered across a range of contexts to change alcohol-related behaviors, attitudes and/or knowledge. This systematic review aimed to identify alcohol education programs addressing young people, and determine whether they changed alcohol-related behavior, knowledge and attitudes; and, ascertain components of successful programs. Studies were identified, guided by the PRISMA review process, from the earliest records until June 2020. Included studies (N = 70) comprised an alcohol education program which focused on young people (15-24 years). Forty programs reported behavior changes, and these programs were the highest quality. Others impacted attitudes and/or knowledge only (n = 12); or reported no impacts (n = 17). Recent programs were more likely than older programs to feature online delivery and report behavior changes. To enhance alcohol education, future programs should include the identified quality criteria, alongside process and long-term outcome evaluations, to better monitor effectiveness. Findings indicated some education programs have capacity to positively change alcohol-related behavior; however, outcome consistency varied even in high-quality programs. Alcohol education programs should be designed alongside health education/promotion models and best-practice recommendations, to improve the likelihood of desirable behavior-related outcomes.

Effectiveness of a voluntary casino self-exclusion online self-management program

Despite evidence for effectiveness, only a small proportion of individuals with gambling disorder ever access treatment and support resources for their problem. Voluntary self-exclusion (VSE) programs are an ideal circumstance to engage individuals who are reluctant or have not yet sought formal treatment, given that individuals are already electing to prevent themselves from gambling through self-exclusion. The present study was a randomized controlled trial of a novel, online VSE self-management intervention. Individuals who chose to self-exclude at gambling venues (N = 201) were randomly assigned to participate in an online self-management program combined with VSE or to an in-person self-awareness educational workshop combined with VSE comparison group. Following a baseline assessment, participants were followed up at three, six, and twelve months via telephone interviews. Measured outcomes were gambling frequency and expenditure, problem gambling scores, problem drinking scores, type of goal set for gambling behaviour, quality of life, and treatment-seeking. The 12-month follow-up rate was 71% (n = 143). Participants in both VSE groups gambled less, spent less money gambling, and reported decreased need for formal treatment. However, there were no significant group differences on any of the primary or secondary outcomes. Only 30-35% of the participants completed their assigned workshop, depending on the group. Results from the online program satisfaction survey revealed that participants generally liked the program and rated the quality of the content highly, but thought there could be improvement regarding interactivity, variety, stimulation and greater clarity around registration steps and program objectives. The online VSE program is an effective alternative to the face-to-face VSE program. Although the outcomes between the two programs were not significantly different, the online program is easier to administer, able to reach more individuals since it only requires access to a computer and is based on motivational evidence-based principles of psychotherapy for gambling disorder.

Effectiveness of the use of implementation intentions on reduction of substance use: A meta-analysis

OBJECTIVE

Background: Substance use, such as alcohol drinking, tobacco smoking and illicit drug use, have been associated with severe health conditions and an annual estimated 12 % of all deaths worldwide. Implementation intentions are self-regulatory processes which help achieve health-related behaviour change.

OBJECTIVES

To investigate the effectiveness of forming implementation intentions to reduce substance use.

DESIGN

Data sources: PsycINFO, MEDLINE, Psychology and Behavioural Science Collection, clinicaltrials.gov, UK Clinical Trials Gateway, Reference lists.

INCLUSION CRITERIA

RCT of substance users forming implementation intentions to reduce consumption (active or passive control condition present).

STUDY APPRAISAL AND SYNTHESIS METHODS

the SIGN checklist for RCT quality was used for quality appraisal, data was extracted by two reviewers.

RESULTS

Twenty-one studies were included in the meta-analysis. The overall effect size for alcohol use was g = 0.31 (95 % CI: 0.21, 0.42), p < .001; for tobacco smoking g = 0.31 (CI: 0.12, 0.5), p = .002; no studies were retrieved for the use of implementation intentions on illicit drug use.

CONCLUSION

This review suggests that implementation intention interventions are effective in reducing some forms of substance use (alcohol use and tobacco smoking), albeit revealing small effect sizes, among the general population and students in secondary and higher education.
