Evaluation of an integrated personalized feedback intervention for hazardous drinkers with elevated anxiety sensitivity and PTSD symptoms: Protocol for a randomized controlled trial.

ABSTRACT:

Background

Hazardous drinking and posttraumatic stress disorder (PTSD) are commonly co-occurring conditions among adults. Motivational enhancement interventions, such as personalized feedback interventions (PFI), have demonstrated efficacy for reducing hazardous drinking. Emerging though scant literature has evaluated PFI for co-occurring PTSD and hazardous alcohol use. A transdiagnostic risk factor that may underlie this co-occurrence and inform novel PFI development is anxiety sensitivity (AS).

Objective

To use a randomized controlled trial to evaluate the efficacy of a novel, computer-based PFI for hazardous drinkers with at least subclinical PTSD and elevated AS (AP-PFI), against a time-matched comparison condition (C-PFI).

Methods

Participants (N = 100) will be recruited and enrolled from the Houston, TX community. The study includes: an in-person visit (baseline diagnostic assessment, a brief intervention, and a post-intervention assessment) and two follow-up assessments (1-week and 1-month). Participants who meet study inclusion criteria will be randomized to one of two conditions at baseline: AP-PFI or C-PFI. AP-PFI will consist of a brief, single-session, computer-delivered, PFI-based intervention that provides integrative and normative feedback about alcohol use, AS, and PTSD symptoms. C-PFI will be time-matched but will only include alcohol-related feedback.

Conclusions

AP-PFI is designed to provide feedback about alcohol use, PTSD symptoms, and AS and their interplay and deliver psychoeducation on harm-reduction techniques, interoceptive exposure exercises, and stress management strategies. The intervention may address extant gaps in treatment for these co-occurring conditions by providing a brief, evidence-based, motivational enhancement intervention that is cost-effective with potential to be disseminated across a variety of healthcare settings.

Project description:OBJECTIVE:Despite its prominence in the health communication literature, psychological reactance has rarely been considered as a factor that may undermine web-based Personalized Normative Feedback (PNF) alcohol interventions for college students. This study built on recent gamification work to examine how chance-based uncertainty, a popular game mechanic associated with motivation and attention in digital games for learning, might be leveraged to reduce the psychological reactance experienced by heavy drinking students receiving alcohol PNF, thereby leading to larger reductions in their alcohol consumption. METHOD:Psychological reactance, perceptions of norms, and drinking behaviors were assessed during a 3-week period following random assignment of binge drinking students (N = 141, 51% female) into one of four web-based PNF conditions. These conditions asked the same questions about drinking and delivered identical PNF on alcohol use but differed in whether animated slot-machine spinners appeared to select participants' question and feedback topics as well as the number of additional topics (beyond alcohol) on which questions were asked and PNF was delivered. RESULTS:All conditions similarly reduced drinking norms but differed in the degree to which they aroused cognitive reactance and reduced drinking. Relative to a no-spinner alcohol-only condition, increasing chance-based uncertainty by giving question and feedback topics the appearance of being selected by gamelike spinners substantially reduced cognitive reactance, which, in turn, reduced drinking 20 days later. Overall, participants experienced the least cognitive reactance when spinners first selected three question topics and later selected two of these topics to deliver feedback on. CONCLUSIONS:Findings suggest that introducing chance-based uncertainty through gamelike spinners, asking questions about multiple topics, and delivering feedback on additional topics unrelated to alcohol together work to reduce the degree to which the task feels like an alcohol intervention overtly aimed at reducing consumption, thereby making the alcohol PNF more effective among heavy drinking students.

Project description:BackgroundNorms clarification has been identified as an effective component of college student drinking interventions, prompting research on norms clarification as a single-component intervention known as Personalized Normative Feedback (PNF). Previous reviews have examined PNF in combination with other components but not as a stand-alone intervention.ObjectivesTo investigate the degree to which computer-delivered stand-alone personalized normative feedback interventions reduce alcohol consumption and alcohol-related harms among college students and to compare gender-neutral and gender-specific PNF.Data sourcesElectronic databases were searched systematically through November 2014. Reference lists were reviewed manually and forward and backward searches were conducted.Selection criteriaOutcome studies that compared computer-delivered, stand-alone PNF intervention with an assessment only, attention-matched, or active treatment control and reported alcohol use and harms among college students.MethodsBetween-group effect sizes were calculated as the standardized mean difference in change scores between treatment and control groups divided by pooled standard deviation. Within-group effect sizes were calculated as the raw mean difference between baseline and follow-up divided by pooled within-groups standard deviation.ResultsEight studies (13 interventions) with a total of 2,050 participants were included. Compared to control participants, students who received gender-neutral (dbetween = 0.291, 95% CI [0.159, 0.423]) and gender-specific PNF (dbetween = 0.284, 95% CI [0.117, 0.451]) reported greater reductions in drinking from baseline to follow-up. Students who received gender-neutral PNF reported 3.027 (95% CI [2.171, 3.882]) fewer drinks per week at first follow-up and gender-specific PNF reported 3.089 (95% CI [0.992, 5.186]) fewer drinks. Intervention effects were small for harms (dbetween = 0.157, 95% CI [0.037, 0.278]).ConclusionsComputer-delivered PNF is an effective stand-alone approach for reducing college student drinking and has a small impact on alcohol-related harms. Effects are small but clinically relevant when considered from a public health perspective. Additional research is needed to examine computer-delivered, stand-alone PNF as a population-level prevention program.
