Substance use and young people: the potential of technology

Comparing satisfaction, alliance and intervention components in electronically delivered and in-person brief interventions for substance use among childbearing-aged women

Electronic delivery of Screening, Brief Intervention, and Referral to Treatment (e-SBIRT) may be a low-cost and high-reach method for screening and brief intervention in health care settings. However, its relative acceptability, ability to build a therapeutic alliance, and delivery of key intervention components compared to in-person SBIRT (SBIRT) is unclear. The association of these factors with intervention outcomes is also not known. We compared SBIRT and e-SBIRT on satisfaction, alliance, and receipt of intervention components, and evaluated the extent to which these intervention dimensions were related to later substance use. Data were collected as part of a randomized clinical trial (N = 439) examining SBIRT, e-SBIRT, and enhanced usual care for childbearing-aged women in two reproductive healthcare clinics (see Martino et al. (2018) for main trial findings). Participants receiving SBIRT or e-SBIRT (N = 270) rated satisfaction and alliance following a single-session, brief intervention, based on motivational interviewing that targeted hazardous substance use (tobacco, alcohol, illicit drugs and prescribed medications). Trained raters coded audio-recorded SBIRT sessions for the presence of six major intervention components, and evaluated the occurrence of these components in the e-SBIRT software. Overall, participants in both groups reported strong satisfaction (on average, "considerably" to "extremely" satisfied) and perceived working alliance (on average, "very often" to "always" allied). SBIRT participants provided higher overall alliance ratings, felt more encouraged to make their own decisions, and rated the intervention's likely helpfulness to other women higher. Fewer e-SBIRT participants received intervention components focusing on personalized feedback, developing importance of and confidence in making changes to substance use, and developing a plan to change, compared to SBIRT participants. However, e-SBIRT participants were equally or more likely to receive components seeking to help them understand their use, discussing reasons for use, and summarizing and supporting what the patients elected to do. Notably, satisfaction, alliance, and number of intervention components received were not associated with total days of substance use. Although we found no evidence that the intervention characteristics evaluated in this study were associated with outcomes, acceptability and alliance may have other important implications. Findings suggest areas for improvement with respect to e-SBIRT satisfaction and alliance formation. ClinicalTrials.govregistration number: NCT01539525.

Comparative Effectiveness of Web-Based vs. Educator-Delivered HIV Prevention for Adolescent Substance Users: A Randomized, Controlled Trial

BACKGROUND

Young people who engage in substance use are at risk for becoming infected with HIV and diseases with similar transmission dynamics. Effective disease prevention programs delivered by prevention specialists exist but are rarely provided in systems of care due to staffing/resource constraints and operational barriers-and are thus of limited reach. Web-based prevention interventions could possibly offer an effective alternative to prevention specialist-delivered interventions and may enable widespread, cost-effective access to evidence-based prevention programming. Previous research has shown the HIV/disease prevention program within the Web-based therapeutic education system (TES) to be an effective adjunct to a prevention specialist-delivered intervention. The present study was the first randomized, clinical trial to evaluate the comparative effectiveness of this Web-based intervention as a standalone intervention relative to a traditional, prevention specialist-delivered intervention.

METHODS

Adolescents entering outpatient treatment for substance use participated in this multi-site trial. Participants were randomly assigned to either a traditional intervention delivered by a prevention specialist (n=72) or the Web-delivered TES intervention (n=69). Intervention effectiveness was assessed by evaluating changes in participants' knowledge about HIV, hepatitis, and sexually transmitted infections, intentions to engage in safer sex, sex-related risk behavior, self-efficacy to use condoms, and condom use skills.

FINDINGS

Participants in the TES intervention achieved significant and comparable increases in HIV/disease-related knowledge, condom use self-efficacy, and condom use skills and comparable decreases in HIV risk behavior relative to participants who received the intervention delivered by a prevention specialist. Participants rated TES as easier to understand.

CONCLUSION

This study indicates that TES is as effective as HIV/disease prevention delivered by a prevention specialist. Because technology-based interventions such as TES have high fidelity, are inexpensive and scalable, and can be implemented in a wide variety of settings, they have the potential to greatly increase access to effective prevention programming.

Brief web-based intervention for college students with comorbid risky alcohol use and depressed mood: does it work and for whom?

College is a time of increased risk for problematic alcohol use and depressed mood. The comorbidity of these conditions is well documented, but is less well understood, with few interventions designed to prevent or reduce the related consequences. The current study evaluated a web-based personalized intervention for students (N=311) who reported an AUDIT score of 8 or more, a BDI-II score of 14 or more, and reported drinking four (women) or five (men) or more drinks on at least one occasion in the past month.

METHOD

Invited participants were randomly selected from all enrolled undergraduates at a large, public, Pacific Northwestern University. Participants completed a screening and baseline assessment, and those who met study eligibility criteria were randomized to one of four conditions (alcohol only, depressed mood only, integrated, and referral-only control). Follow-up occurred one-month post-intervention.

RESULTS

While no main effects for the interventions were found, there were moderation effects, such that students in the alcohol only and integrated conditions who had lower levels of depressed mood or alcohol-related problems at baseline showed greater reductions in alcohol-related problems at follow-up compared to students in the control condition. Implications for interventions are discussed.

[Data quality in surveys on alcohol consumption among university students]

Different survey modalities have been developed to assess alcohol consumption and related problems. Research that compares data quality between survey modalities is scarce in Latin America. The aim of this study was to assess data quality in three survey modalities on alcohol consumption: self-administered online, self-administered hard-copy, and face-to-face interviews. Data were obtained from three probabilistic samples of students (n = 60 each) from the National University of Mar del Plata, Argentina, using the same questionnaire. Data quality was measured for each modality by overall response rate, item response rate, and accuracy. Data accuracy was evaluated as the percentage of self-reported binge drinking, positive results on AUDIT, and internal consistency of AUDIT for each modality. The overall and item response rates were lower in the online modality and similar between the other two. No differences were found between modalities in the accuracy of responses.

Media campaigns for the prevention of illicit drug use in young people

BACKGROUND

Substance-specific mass media campaigns which address young people are widely used to prevent illicit drug use. They aim to reduce use and raise awareness of the problem.

OBJECTIVES

To assess the effectiveness of mass media campaigns in preventing or reducing the use of or intention to use illicit drugs amongst young people.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2013, Issue 1), including the Cochrane Drugs and Alcohol Group's Specialised Register; MEDLINE through PubMed (from 1966 to 29 January 2013); EMBASE (from 1974 to 30 January 2013) and ProQuest Dissertations & Theses A&I (from 1861 to 3 February 2013).

SELECTION CRITERIA

Cluster-randomised controlled trials, prospective and retrospective cohort studies, interrupted time series and controlled before and after studies evaluating the effectiveness of mass media campaigns in influencing drug use, intention to use or the attitude of young people under the age of 26 towards illicit drugs.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures of The Cochrane Collaboration.

MAIN RESULTS

We included 23 studies involving 188,934 young people, conducted in the USA, Canada and Australia between 1991 and 2012. Twelve studies were randomised controlled trials (RCT), two were prospective cohort studies (PCS), one study was both a RCT and a PCS, six were interrupted time series and two were controlled before and after (CBA) studies. The RCTs had an overall low risk of bias, along with the ITS (apart from the dimension 'formal test of trend'), and the PCS had overall good quality, apart from the description of loss to follow-up by exposure.Self reported or biomarker-assessed illicit drug use was measured with an array of published and unpublished scales making comparisons difficult. Pooled results of five RCTs (N = 5470) show no effect of media campaign intervention (standardised mean difference (SMD) -0.02; 95% confidence interval (CI) -0.15 to 0.12).We also pooled five ITS studies (N = 26,405) focusing specifically on methamphetamine use. Out of four pooled estimates (two endpoints measured in two age groups), there was evidence of a reduction only in past-year prevalence of methamphetamine use among 12 to 17 years old.A further five studies (designs = one RCT with PCS, two PCS, two ITS, one CBA, N = 151,508), which could not be included in meta-analyses, reported a drug use outcome with varied results including a clear iatrogenic effect in one case and reduction of use in another.

AUTHORS' CONCLUSIONS

Overall the available evidence does not allow conclusions about the effect of media campaigns on illicit drug use among young people. We conclude that further studies are needed.

Computer-assisted HIV prevention for youth with substance use disorders

We developed an interactive, customizable, Web-based program focused on the prevention of HIV, sexually transmitted infections, and hepatitis among youth. Results from a randomized, controlled trial with youth in treatment for substance use demonstrated that this Web-based tool, when provided as an adjunct to an educator-delivered prevention intervention, increased accurate prevention knowledge, increased intentions to carefully choose partners, and was perceived as significantly more useful relative to the educator-delivered intervention when provided alone. Results suggest this Web-based program may be effective and engaging and may increase the adoption of effective HIV and disease prevention science for youth. Limitations are discussed.

A computerized harm minimization prevention program for alcohol misuse and related harms: randomized controlled trial

AIMS

Hazardous alcohol use is a leading cause of death among adolescents and young adults world-wide, yet few effective prevention interventions exist. This study was the first to examine a computerized harm minimization intervention to reduce alcohol misuse and related harms in adolescents.

DESIGN

Cluster randomized controlled trial of a six-session curriculum-integrated harm minimization prevention program. The intervention was delivered by computer in the form of a teenage drama, which provided education through alcohol-related scenarios to which young people could relate.

SETTING

Schools in Australia.

PARTICIPANTS

A total of 1466 year 8 students (13 years) from 16 high schools in Australia were allocated randomly to a computerized prevention program (n = 611, eight schools) or usual classes (n = 855, eight schools).

MEASUREMENTS

Change in knowledge, alcohol use, alcohol-related harms and alcohol expectancies.

FINDINGS

A computerized prevention program was more effective than usual classes in increasing alcohol-related knowledge of facts that would inform safer drinking choices and decreasing the positive social expectations which students believed alcohol may afford. For females it was effective in decreasing average alcohol consumption, alcohol-related harms and the frequency of drinking to excess (more than four standard drinks; 10 g ethanol). For males the behavioural effects were not significant.

CONCLUSIONS

A harm minimization approach is effective in educating young people about alcohol-related risks and is effective in reducing risky drinking and harms among girls. Reduction of problems among boys remains a challenge.

Encouraging physicians to screen for and intervene in substance use disorders: obstacles and strategies for change

The scientific literature was reviewed to identify obstacles and effective ways to improve primary care physician screening, interventions, and management of patient substance use disorders (SUDs). Major obstacles identified are physician lack of skills and self-efficacy in patient counseling, inadequate training at all levels of medical education, and lack of reimbursement and other health care systems support for services to patients. Physician abuse of drugs does not appear to be a major obstacle. Physician attitudes about patients with SUDS and the effectiveness of treatment services need to be addressed. Research points to the use of a multifaceted change strategy. Key components include practice-based training emphasizing screening and counseling skills throughout medical education, clinical systems to ensure regular SUD services (screening, intervention, and referral) to patients, and reimbursement and coverage systems to support physician interventions and patient services.
