Abstract
Background and aims Unhealthy alcohol use is common and causes tremendous harm. Most people with unhealthy alcohol use will never seek formal alcohol treatment. As an alternative, smartphone apps have been developed as one means to provide help to people concerned about their alcohol use. The aim of this study was to test the efficacy of a smartphone app targeting unhealthy alcohol consumption in a general population sample. Methods Participants were recruited from across Canada using online advertisements. Eligible participants who consented to the trial were asked to download a research-specific version of the app and were provided with a code that unlocked it (a different code for each participant to prevent sharing). Those who entered the code were randomized to one of two different versions of the app: 1) the Full app containing all intervention modules; or 2) the Educational only app, containing only the educational content of the app. Participants were followed-up at 6 months. The primary outcome variable was number of standard drinks in a typical week. Secondary outcome variables were frequency of heavy drinking days and experience of alcohol-related problems. Results A total of 761 participants were randomized to a condition. The follow-up rate was 81 %. A generalized linear mixed model revealed that participants receiving the full app reduced their typical weekly alcohol consumption to a greater extent than participants receiving the educational only app (incidence rate ratio 0.89; 95 % confidence interval 0.80 to 0.98). No significant differences were observed in the secondary outcome variables (p > .05). Discussion and conclusion The results of this trial provide some supportive evidence that smartphone apps can reduce unhealthy alcohol consumption. As this is the second randomized controlled trial demonstrating an impact of this same app (the first one targeted unhealthy alcohol use in university students), increased confidence is placed on the potential effectiveness of the smartphone app employed in the current trial.ClinicalTrials.org number: NCT04745325.

Abstract
PURPOSE Community college (CC) students represent an at-risk population for alcohol use with limited access to campus interventions. The Brief Alcohol Screening and Intervention for College Students (BASICS) is available online, though identifying CC students at risk and connecting them to interventions remains challenging. This study tested a novel approach using social media to identify at-risk students and prompt delivery of BASICS. METHODS This randomized controlled trial examined the feasibility and acceptability of Social Media-BASICS. Participants were recruited from five CCs. Baseline procedures included a survey and social media friending. Social media profiles were evaluated using content analysis monthly for nine months. Intervention prompts included displayed alcohol references indicating escalation of or problematic alcohol use. Participants who displayed such content were randomized into the BASICS intervention or an active control. Measures and analyses assessed feasibility and acceptability. RESULTS A total of 172 CC students completed the baseline survey, mean age was 22.9 (standard deviation = 3.18) years. Most were female (81%), with many (67%) identifying as White. Among participants, 120 (70%) displayed alcohol references on social media, prompting intervention enrollment. Of randomized participants, 94 (93%) completed the preintervention survey within 28 days of the invitation. The majority of participants reported positive intervention acceptability. DISCUSSION This intervention combined two validated approaches: identification of problem alcohol use displays on social media, and provision of the Web-BASICS intervention. Findings demonstrate the feasibility for novel web-based interventions to reach CC populations.

Abstract
Background In Denmark, approximately 150,000 people have alcohol use disorder (AUD). However, only approximately 10% seek AUD treatment, preferably outside conventional health care settings and opening hours. The AUD treatment area experiences low adherence to treatment, as well as high numbers of no-show and premature dropouts. Objective The purpose of the Blend-A (Blended Treatment for Alcohol Use Disorder) feasibility and pilot study was to describe the process of translating and adapting the Dutch treatment protocol into Danish and Danish culture with a high amount of user involvement and to report how patients and therapists perceived the adapted version, when trying it out. Methods The settings were 3 Danish public municipal outpatient alcohol clinics. Study participants were patients and therapists from the 3 settings. Data consisted of survey data from the System Usability Scale, individual patient interviews, and therapist group interviews. Statistical analyses were conducted using the Stata software and Excel. Qualitative analysis was conducted using a theoretical thematic analysis. Results The usability of the treatment platform was rated above average. The patients chose to use the blended treatment format because it ensured anonymity and had a flexible design. Platform use formed the basis of face-to-face sessions. The use of the self-determined platform resulted in a more thorough process. Patient involvement qualified development of a feasible system. Managerial support for time use was essential. Guidance from an experienced peer was useful. Conclusions This study indicates that, during the processes of translating, adapting, and implementing blended, guided, internet-based, and face-to-face AUD treatment, it is relevant to focus on patient involvement, managerial support, and guidance from experienced peers. Owing to the discrete and flexible design of the blended offer, it appears that it may reach patient groups who would not otherwise have sought treatment. Therefore, blended treatment may increase access to treatment and contribute to reaching people affected by excessive alcohol use, who would not otherwise have sought treatment. In addition, it seems that the blended offer may enhance the participants’ perceived satisfaction and the effect of the treatment course. Thus, it appears that Blend-A may be able to contribute to existing treatment offers. Such findings highlight the need to determine the actual effect of the Blend-A offer; therefore, an effectiveness study with a controlled design is warranted.

BLEND-A: blending internet treatment into conventional face-to-face treatment for alcohol use disorder - a study protocol. BMC Psychiatry 2021; 21:131. [PMID: 33676429 PMCID: PMC7937233 DOI: 10.1186/s12888-021-03122-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 02/17/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND A major challenge to psychological treatment for alcohol use disorder (AUD) is patient non-compliance. A promising new treatment approach that is hypothesized to increase patient compliance is blended treatment, consisting of face-to-face contact with a therapist combined with modules delivered over the internet within the same protocol. While this treatment concept has been developed and proven effective for a variety of mental disorders, it has not yet been examined for AUD. AIMS The study described in this protocol aims to examine and evaluate patient compliance with blended AUD treatment as well as the clinical and cost effectiveness of such treatment compared to face-to-face treatment only. METHODS The study design is a pragmatic, stepped-wedge cluster randomized controlled trial. The included outpatient institutions (planned number of patients: n = 1800) will be randomized in clusters to implement either blended AUD treatment or face-to-face treatment only, i.e. treatment as usual (TAU). Both treatment approaches consist of motivational interviewing and cognitive behavioral therapy. Data on sociodemographics, treatment (e.g. intensity, duration), type of treatment conclusion (compliance vs. dropout), alcohol consumption, addiction severity, consequences of drinking, and quality of life, will be collected at treatment entry, at treatment conclusion, and 6 months after treatment conclusion. The primary outcome is compliance at treatment conclusion, and the secondary outcomes include alcohol consumption and quality of life at six-months follow-up. Data will be analyzed with an Intention-to-treat approach by means of generalized linear mixed models with a random effect for cluster and fixed effect for each step. Also, analyses evaluating cost-effectiveness will be conducted. DISCUSSION Blended treatment may increase treatment compliance and thus improve treatment outcomes due to increased flexibility of the treatment course. Since this study is conducted within an implementation framework it can easily be scaled up, and when successful, blended treatment has the potential to become an alternative offer in many outpatient clinics nationwide and internationally.

Abstract
Background Two randomized controlled trials (RCTs) were conducted to explore the utility of the Mechanical Turk (MTurk) crowdsourcing platform to conduct rapid trials evaluating online interventions for unhealthy alcohol use. Methods Both trials employed a staged recruitment procedure where participants who drank in an unhealthy fashion were identified using a baseline survey and then invited to take part in a 6-month follow-up. Participants in both trials were randomized to receive one of several different online interventions or to a no intervention control condition. In study 1, the online interventions were password protected and only those who accessed the study portal were randomized to condition. In study 2, participants were directed to free-of charge interventions and asked to send a screenshot of the intervention to demonstrate that they had complied. Results Participants reporting unhealthy alcohol use were recruited fairly rapidly. Large numbers of screeners were completed (Study 1: n = 4910; Study 2: n = 5812), found eligible (Study 1: n = 3741; Study 2: n = 4095), and randomized to condition (Study 1: n = 511; Study 2: n = 878). Fair follow-up rates were observed at 6 months for each study (Study 1: 82%; Study 2: 66%). Neither trial was able to clearly demonstrate that providing access to the online interventions lead to increased reductions in alcohol use as compared to the control group. Conclusions While recruitment through a crowdsourcing platform is rapid and relatively low cost, it is possible that the lack of impact of the online websites employed in these trials could be due to the source of participants rather than the lack of efficacy of the interventions.

Abstract
BACKGROUND Web-based personalized normative feedback (PNF) interventions are less effective than their laboratory versions. Participant motivation may account for this reduced effect, but there is only a limited amount of research into the influence of motivation on PNF effectiveness. We evaluated the effectiveness of a web-based PNF in reducing alcohol use and consequences among college students with different motivation levels. METHODS Pragmatic randomized controlled trial among Brazilian college drinkers aged 18-30 years (N = 4460). Participants were randomized to a Control or PNF group and followed-up after one (T1), three (T2) and six (T3) months. Outcomes were: AUDIT score (primary outcome), the number of consequences, and the typical number of drinks. Motivation for receiving the intervention was assessed with a visual analog scale (range: 0-10). Generalized mixed models assessed intervention effects via two paradigms: observed cases and attrition models. RESULTS PNF reduced the number of typical drinks at T1 (OR = 0.71, p = 0.002), T2 (OR = 0.60, p < 0.001) and T3 (OR = 0.68, p = 0.016), compared to the control. Motivated students (score ≥3) receiving PNF also reduced the number of typical drinks at T1 (OR = 0.60, p < 0.001), T2 (OR = 0.55, p < 0.001) and T3 (OR = 0.56, p = 0.001), compared to the control. However, the attrition models were more robust at T1 and T2. In contrast, low-motivated students receiving the PNF increased AUDIT score at T3 (b = 1.49, p < 0.001). CONCLUSIONS The intervention reduced alcohol use, and motivation for receiving the intervention moderated the intervention effects. Motivated students reduced their typical alcohol use, whereas low-motivated students increased their AUDIT score.

Abstract
Introduction. Drinking alcohol has detrimental health consequences, and effective interventions to reduce hazardous drinking are needed. The self-regulation intervention of Mental Contrasting with Implementation Intentions (MCII) promotes behavior change across a variety of health behaviors. In this study, we tested if online delivery of MCII reduced hazardous drinking in people who were worried about their drinking. Method. Participants (N = 200, female = 107) were recruited online. They were randomized to learn MCII or solve simple math problems (control). Results. Immediately after the intervention, participants in the MCII condition (vs. control) reported an increased commitment to reduce drinking. After 1 month, they reported having taken action measured by the Readiness to Change drinking scale. When drinking was hazardous (Alcohol Use Disorders Identification Test ≥ 8, n = 85), participants in the MCII condition indicated a decreased number of drinking days, exp(β) = 0.47, CI (confidence interval) [-1.322, -.207], p = .02, and drinks per week, exp(β) = 0.57, CI [0.94, 5.514], p = .007, compared with the control condition. Discussion. These findings demonstrate that a brief, self-guided online intervention (Mdn = 28 minutes) can reduce drinking in people who worry about their drinking. Our findings show a higher impact in people at risk for hazardous drinking. Conclusion. MCII is scalable as an online intervention. Future studies should test the cost-effectiveness of the intervention in real-world settings.

Abstract
As part of a multicenter project supported by the World Health Organization, we developed a web-based intervention to reduce alcohol use and related problems. We evaluated the predictors of adherence to, and the outcomes of the intervention. Success was defined as a reduction in consumption to low risk levels or to <50% of the baseline levels of number of drinks. From the 32,401 people who accessed the site, 3389 registered and 929 completed the full Alcohol Use Disorders Identification Test (AUDIT), a necessary condition to be considered eligible to take part in the intervention. Based on their AUDIT scores, these participants were classified into: low risk users (LRU; n=319) harmful/hazardous users (HHU; n=298) or suggestive of dependence users (SDU; n=312). 29.1% of the registered users (LRU=42; HHU=90; SDU=82) completed the evaluation form at the end of the six-week period, and 63.5% reported low-risk drinking levels. We observed a significant reduction in alcohol consumption in the HHU (62.5%) and SDU (64.5%) groups in relation to baseline. One month after the intervention, in the follow-up, 94 users filled out the evaluation form, and their rate of success was similar to the one observed in the previous evaluation. Logistic regression analyses indicated that HHU participants presented higher adherence than LRU. Despite a relatively low adherence to the program, its good outcomes and low cost, as well as the high number of people that can be reached by a web-based intervention, suggest it has good cost-effectiveness.

Abstract
BACKGROUND Problem drinking causes great harm to the person and to society. Most problem drinkers will never seek treatment. The current trial will test the efficacy of two Internet interventions for problem drinking - one minimal and the other extended - as an alternate means of providing help to those in need. METHODS/DESIGN A double blinded, four-wave panel design with random assignment to two experimental conditions will be used in this study. Participants will be recruited through a comprehensive recruitment strategy consisting of online and print advertisements asking for people who are 'interested in helping us develop and evaluate Internet-based interventions for problem drinkers.' Potential participants will be screened to select problem drinkers who have home access to the Internet. Participants will be sent to a password-protected Internet site and, upon signing in, will be randomized to be provided access to the minimal or extended Internet-based intervention. Six-month, twelve-month, and two-year drinking outcomes will be compared between experimental conditions. The primary hypothesis is that participants in the extended Internet intervention condition will display significantly improved drinking outcomes at twelve months compared to participants in the minimal intervention. DISCUSSION The findings of this trial will contribute to the growing literature on Internet interventions for problem drinkers. In addition, findings from this trial will contribute to the scarce literature available evaluating the long-term efficacy of brief interventions for alcohol problems.

Effectiveness of guided and unguided low-intensity internet interventions for adult alcohol misuse: a meta-analysis. PLoS One 2014; 9:e99912. [PMID: 24937483 PMCID: PMC4061051 DOI: 10.1371/journal.pone.0099912] [Citation(s) in RCA: 203] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2014] [Accepted: 05/19/2014] [Indexed: 01/16/2023] Open
Abstract
Background Alcohol misuse ranks within the top ten health conditions with the highest global burden of disease. Low-intensity, Internet interventions for curbing adult alcohol misuse have been shown effective. Few meta-analyses have been carried out, however, and they have involved small numbers of studies, lacked indicators of drinking within low risk guidelines, and examined the effectiveness of unguided self-help only. We therefore conducted a more thorough meta-analysis that included both guided and unguided interventions. Methods Systematic literature searches were performed up to September 2013. Primary outcome was the mean level of alcohol consumption and drinking within low risk guidelines for alcohol consumption at post-treatment. Findings We selected 16 randomised controlled trials (with 23 comparisons and 5,612 participants) for inclusion. Results, showed a small but significant overall effect size in favour of Internet interventions (g = 0.20, 95% CI: 0.13–0.27, p<.001). Participants in Internet interventions drunk on average 22 grams of ethanol less than controls and were significantly more likely to be adhering to low-risk drinking guidelines at post-treatment (RD 0.13, 95% CI: 0.09–0.17, p<.001). Subgroup analyses revealed no significant differences in potential moderators for the outcome of alcohol consumption, although there was a near-significant difference between comparisons with waitlist control and those with assessment-only or alcohol information control conditions (p = .056). Conclusions Internet interventions are effective in reducing adult alcohol consumption and inducing alcohol users to adhere to guidelines for low-risk drinking. This effect is small but from a public health point of view this may warrant large scale implementation at low cost of Internet interventions for adult alcohol misuse. Moderator analyses with sufficient power are, however, needed in order to assess the robustness of these overall results and to assess whether these interventions may impact on subgroups with different levels of success.

Abstract
Background There are a number of evidence-based, in-person clinical inteventions for problem drinkers, but most problem drinkers will never seek such treatments. Reaching the population of non-treatment seeking problem drinkers will require a different approach. Accordingly, this randomized clinical trial evaluated an intervention that has been validated in clinical settings and then modified into an ultra-brief format suitable for use as an indicated public health intervention (i.e., targeting the population of non-treatment seeking problem drinkers). Methodology/Principal Findings Problem drinkers (N = 1767) completed a baseline population telephone survey and then were randomized to one of three conditions – a personalized feedback pamphlet condition, a control pamphlet condition, or a no intervention control condition. In the week after the baseline survey, households in the two pamphlet conditions were sent their respective interventions by postal mail addressed to ‘Check Your Drinking.’ Changes in drinking were assessed post intervention at three-month and six-month follow-ups. The follow-up rate was 86% at three-months and 76% at six-months. There was a small effect (p = .04) in one of three outcome variables (reduction in AUDIT-C, a composite measure of quantity and frequency of drinking) observed for the personalized feedback pamphlet compared to the no intervention control. No significant differences (p>.05) between groups were observed for the other two outcome variables – number of drinks consumed in the past seven days and highest number of drinks on one occasion. Conclusions/Significance Based on the results of this study, we tentatively conclude that a brief intervention, modified to an ultra-brief, public health format can have a meaningful impact. Trial Registration ClinicalTrials.gov NCT00688584.

Abstract
OBJECTIVE While research has documented heavy drinking practices and associated negative consequences of college students turning 21, few studies have examined prevention efforts aimed at reducing high-risk drinking during 21st birthday celebrations. The present study evaluated the comparative efficacy of a general prevention effort (i.e., Brief Alcohol Screening and Intervention for College Students, or BASICS) and event-specific prevention in reducing 21st birthday drinking and related negative consequences. Furthermore, this study evaluated inclusion of peers in interventions and mode of intervention delivery (i.e., in-person vs. via the Web). METHOD Participants included 599 college students (46% male): men who intended to consume at least 5 drinks and women who intended to consume at least 4 drinks on their 21st birthday. After completing a screening/baseline assessment approximately 1 week before turning 21, participants were randomly assigned to 1 of 6 conditions: 21st birthday in-person BASICS, 21st birthday web BASICS, 21st birthday in-person BASICS plus friend intervention, 21st birthday web BASICS plus friend intervention, BASICS, or an attention control. A follow-up assessment was completed approximately 1 week after students' birthdays. RESULTS Results indicated a significant intervention effect for BASICS in reducing blood alcohol content reached and number of negative consequences experienced. All 3 in-person interventions reduced negative consequences experienced. Results for the web-based interventions varied by drinking outcome and whether a friend was included. CONCLUSIONS Overall, results provide support for both general intervention and ESP approaches across modalities for reducing extreme drinking and negative consequences associated with turning 21. These results suggest there are several promising options for campuses seeking to reduce both use and negative consequences associated with 21st birthday celebrations.

Abstract
Our objectives were to review the effectiveness of psychosocial modalities in the treatment of alcohol use disorders and problems, and to examine the impact of therapists on treatment outcome, the evidence on best practices for comorbid conditions, and the evidence on treatment matching. We based our review on published systematic reviews of this topic after 2000. There is strong evidence that some, but not all, psychosocial treatments are effective in treating alcohol problems. Those with the strongest empirical support are motivational enhancement therapy, various cognitive-behavioural interventions, and brief interventions. Meta-analyses for several of these modalities suggest typical effect sizes in the low-to-moderate range. When these modalities have been compared with one another in well-designed clinical trials, they have been shown to be of comparable effectiveness. There is little basis on which to recommend one of these modalities over another but good reason to select from among them.

Abstract
The goal of this research was to understand why some people use online interventions for drinking problems, whereas others with comparable access to the interventions do not. As part of a randomized controlled trial, 92 participants in the experimental condition were provided access to a password-protected version of a Web-based personalized feedback intervention (the Check Your Drinking [CYD] screener, www.CheckYourDrinking.net). Information collected at baseline was compared between those who accessed the Web site and those who did not. Those who accessed the Web site tended to be more frequent users of the Internet, to drink less, and to perceive that others of the same age and gender drank less as compared with those who did not access the intervention. Some of these results are troubling as the preferred target of this type of intervention would be those who drink more and perceive that others are also heavy alcohol consumers.

Abstract
Potentially harmful substance use is common, but many affected people do not receive treatment. Brief face-to-face treatments show impact, as do strategies to assist self-help remotely, by using bibliotherapies, computers or mobile phones. Remotely delivered treatments offer more sustained and multifaceted support than brief interventions, and they show a substantial cost advantage as users increase in number. They may also build skills, confidence and treatment fidelity in providers who use them in sessions. Engagement and retention remain challenges, but electronic treatments show promise in engaging younger populations. Recruitment may be assisted by integration with community campaigns or brief opportunistic interventions. However, routine use of assisted self-help by standard services faces significant challenges. Strategies to optimize adoption are discussed.

Abstract
OBJECTIVE Web-based brief alcohol interventions have the potential to reach a large number of individuals at low cost; however, few controlled evaluations have been conducted to date. The present study was designed to evaluate the efficacy of gender-specific versus gender-nonspecific personalized normative feedback (PNF) with single versus biannual administration in a 2-year randomized controlled trial targeting a large sample of heavy-drinking college students. METHOD Participants included 818 freshmen (57.6% women; 42% non-Caucasian) who reported 1 or more heavy-drinking episodes in the previous month at baseline. Participants were randomly assigned in a 2 (gender-specific vs. gender-nonspecific PNF) × 2 (single vs. biannual administration of PNF) + 1 (attention control) design. Assessments occurred every 6 months for a 2-year period. RESULTS Results from hierarchical generalized linear models provided modest effects on weekly drinking and alcohol-related problems but not on heavy episodic drinking. Relative to control, gender-specific biannual PNF was associated with reductions over time in weekly drinking (d = -0.16, 95% CI [-0.02, -0.31]), and this effect was partially mediated by changes in perceived norms. For women, but not men, gender-specific biannual PNF was associated with reductions over time in alcohol-related problems relative to control (d = -0.29, 95% CI [-0.15, -0.58]). Few other effects were evident. CONCLUSIONS The present research provides modest support for the use of biannually administered web-based gender-specific PNF as an alternative to more costly indicated prevention strategies.

Abstract
Background Unhealthy alcohol use among university students is cause for concern, yet the level of help seeking behavior for alcohol use is low within the student population. Electronic brief interventions delivered via the Internet present an alternative to traditional treatments and could enable the delivery of interventions on a population basis. Further evidence is needed of the effectiveness of Internet-delivered interventions and of their generalizability across educational institutions. Objective Our objective was to evaluate the effectiveness across 4 UK universities of a Web-based intervention for student alcohol use. Methods In total, 1112 participants took part. Participants were stratified by educational institution, gender, age group, year of study, and self-reported weekly consumption of alcohol and randomly assigned to either the control arm or to the immediate or delayed intervention arms. Intervention participants gained access to the intervention between weeks 1 to 7 or weeks 8 to 15, respectively. The intervention provided electronic personalized feedback and social norms information on drinking behavior accessed by logging on to a website. Participants registered interest by completing a brief screening questionnaire and were then asked to complete 4 further assessments across the 24 weeks of the study. Assessments included a retrospective weekly drinking diary, the Alcohol Use Disorders Identification Test (AUDIT), and a readiness-to-change algorithm. The outcome variable was the number of units of alcohol consumed in the last week. The effect of treatment arm and time on units consumed last week and average units consumed per drinking occasion were investigated using repeated measures multivariate analysis of covariance (MANCOVA). In addition, the data were modeled using a longitudinal regression with time points clustered within students. Results MANCOVA revealed a main effect of time on units of alcohol consumed over the last week. A longitudinal regression model showed an effect of assessment across time predicting that participants who completed at least 2 assessments reduced their drinking. The model predicted an additional effect of being assigned to an intervention arm, an effect that increased across time. Regression analysis predicted that being male or being assigned to an intervention arm increased the odds of not completing all assessments. The number of units of alcohol consumed over the last week at registration, age, university educational institution, and readiness to change were not predictive of completion. Conclusions Delivering an electronic personalized feedback intervention to students via the Internet can be effective in reducing weekly alcohol consumption. The effect does not appear to differ by educational institution. Our model suggested that monitoring alone is likely to reduce weekly consumption over 24 weeks but that consumption could be further reduced by providing access to a Web-based intervention. Further research is needed to understand the apparent therapeutic effect of monitoring and how this can be utilized to enhance the effectiveness of brief Web-based interventions.

Abstract
OBJECTIVE Misuse of alcohol imposes a major public health cost, yet few problem drinkers are willing to access in-person services for alcohol abuse. The development of brief, easily accessible ways to help problem drinkers who are unwilling or unable to seek traditional treatment services could therefore have significant public health benefit. The objective of this project is to conduct a randomized controlled evaluation of the internet-based Check Your Drinking (CYD) screener ( http://www.CheckYourDrinking.net). METHOD Participants (n = 185) recruited through a general telephone population survey were assigned randomly to receive access to the CYD, or to a no-intervention control group. RESULTS Follow-up rates were excellent (92%). Problem drinkers provided access to the CYD displayed a six to seven drinks reduction in their weekly alcohol consumption (a 30% reduction in typical weekly drinking) at both the 3- and 6-month follow-ups compared to a one drink per week reduction among control group respondents. CONCLUSIONS The CYD is one of a growing number of internet-based interventions with research evidence supporting its efficacy to reduce alcohol consumption. The internet could increase the range of help-seeking options available because it takes treatment to the problem drinker rather than making the problem drinker come to treatment.

Abstract
INTRODUCTION AND AIMS In recent years, there has been an increase in the number of Internet-based interventions (IBI) for alcohol problems and other addictive behaviours. However, it is risky to assume interventions that have been found to work in face-to-face modalities can be translated into IBI that are equally effective. DESIGN AND METHODS Using selected examples from the published works, this paper will identify some of the special considerations that are relevant to the evaluation of IBI. In addition, methodological issues found in the ongoing development and evaluation of the Check Your Drinking screener (http://www.CheckYourDrinking.net), an IBI for problem drinkers, will be discussed. RESULTS There have been several randomised control trials with promising results. A primary limitation of much of the research conducted to date is concerns regarding the generalisability of the findings. DISCUSSION AND CONCLUSIONS. Caution should be taken in assuming that the IBI, which have been found to work in tightly controlled efficacy trials, will display similar levels of effectiveness when used in 'naturalistic' settings (i.e. not face-to-face in a research environment). Positive results from studies using a variety of different research designs will advance the potential for IBI, as a new means of helping problem drinkers reduce their alcohol consumption. Because of their accessibility and anonymity, IBI could facilitate a broad provision of treatment services at a population level.

Abstract
AIM The aim of this work was to report on the results of a pilot study of a web-based self-assessment service (DHT) for Finnish drinkers (www.paihdelinkki.fi/testaa/juomatapatesti). METHOD During the 7-month recruitment period in 2004 altogether 22,536 anonymous self-assessments were recorded in the database of this service. The study sample was recruited from the 1598 service users who also participated to a survey evaluating the DHT. Those who consented by providing required baseline data and their e-mail address (n = 343) were sent a message asking them to fill in the follow-up questions 3, 6 and 12 months later. Their self-reported use of alcohol and drinking-related problems served as the main outcome variables in this single-group follow-up study. RESULTS At 3, 6 and 12 months, 78%, 69% and 61% of the study participants, respectively, responded to the follow-up. The intention-to-treat (ITT) results revealed significant reductions (P < 0.001) in all the outcome measures. The reductions occurred during the first 3 months, after which the changes were non-significant. CONCLUSIONS The results are in line with previous studies with mostly shorter follow-up periods suggesting that Internet-based self-assessment services can be useful tools in reducing excessive drinking. A randomized controlled trial would, however, increase our certainty about the causes of the observed changes.

Abstract
AIMS Self-help interventions for adult problem drinkers in the general population have proved effective. The question is whether this also holds for self-help interventions delivered over the internet. DESIGN We conducted a pragmatic randomized trial with two parallel groups, using block randomization stratified for gender and with follow-up at 6 months. SETTING The intervention and trial were conducted online in the Netherlands in 2003-2004. PARTICIPANTS We selected 261 adult problem drinkers from the general population with a weekly alcohol consumption above 210 g of ethanol for men or 140 g for women, or consuming at least 60 g (men) or 40 g (women) at least 1 day a week over the past 3 months. Participants were randomized to either the experimental drinking less (DL) condition or to the control condition (PBA). INTERVENTION DL is a web-based, multi-component, interactive self-help intervention for problem drinkers without therapist guidance. The recommended treatment period is 6 weeks. The intervention is based on cognitive-behavioural and self-control principles. The control group received access to an online psychoeducational brochure on alcohol use (PBA). OUTCOME MEASURES We assessed the following outcome measures at 6-month follow-up: (i) the percentage of participants who had reduced their drinking levels to within the normative limits of the Dutch guideline for low-risk drinking; and (ii) the reduction in mean weekly alcohol consumption. FINDINGS At follow-up, 17.2% of the intervention group participants had reduced their drinking successfully to within the guideline norms; in the control group this was 5.4% [odds ratio (OR) = 3.66; 95% confidence interval (CI) 1.3-10.8; P = 0.006; number needed to treat (NNT) = 8.5]. The intervention subjects decreased their mean weekly alcohol consumption significantly more than control subjects, with a difference of 12.0 standardized units (95% CI 5.9-18.1; P < 0.001; standardized mean difference 0.40). CONCLUSIONS To our knowledge this is one of the first randomized controlled trials on a web-based self-help intervention without therapist guidance for self-referred problem drinkers among the adult general population. The intervention showed itself to be effective in reducing problem drinking in the community.

Abstract
Despite the development of brief efficacious interventions, they are not reaching a large proportion of college students who continue to drink in a manner that puts them at risk for harm. Recent efforts have attempted to address this issue through the development of brief alcohol interventions that may be more broadly disseminated to college students. Researchers have adapted a variety of approaches to print and computer-based modalities that do not require direct real-time contact with an interventionist. The goal of this paper is to review the empirical evidence for the utility of these brief alcohol interventions that are delivered without direct real-time contact. A systematic review of this research suggests that 'no-contact' interventions are feasible and may have efficacy. Further research is needed to understand the duration of these effects, mechanisms of change, moderators of outcome, and how to enhance the effectiveness of these approaches.

Abstract
This study aims to make an initial evaluation of an Internet-based self-assessment tool for Finnish drinkers () and its effects on their use of alcohol. The subjects (n=343) were recruited from among the 1598 anonymous respondents to the survey on this self-assessment service. The subjects' baseline data were first compared to those of a random sample of the users of this Internet service during the same period. Their responses to the survey were then analyzed. Finally, their drinking and drinking-related problems at the baseline and 3 months later were compared. The study participants were heavier drinkers than the average users of this Internet service. More than nine out of ten were satisfied with the service. The response rate to the follow-up was 78%. There were highly significant reductions (p=.000) in all the outcome measures. The service appealed more to women than men, but there were no sex differences in drinking-related outcomes. The results supported the further development of this model to a randomized controlled trial.

Abstract
Health communication appeals were utilized through a Web site simulation to evaluate the potential effectiveness of 3 intervention approaches to promote responsible drinking among college students. Within the Web site simulation, participants were exposed to a persuasive message designed to represent either the generalized social norms advertising approach (based on others' behavior), the personalized behavioral feedback approach (tailored to the individual's behavior), or the schema-based approach (tailored to the individual's self-schema, or personality). A control group was exposed to a message that was designed to be neutral (it was designed to discourage heavy drinking, but it did not represent any of the previously mentioned approaches). It was hypothesized that the more personalized the message was to the individual, the more favorable college students' attitudes would be toward the responsible drinking message. Participants receiving the more personalized messages did report more favorable attitudes toward the responsible drinking message.

Abstract
Background In recent years, online services for problem drinkers have been developed. This paper describes ongoing efforts to improve one of these services, the Alcohol Help Center. Objective This report summarizes new modules added to the Check Your Drinking (CYD) screener, a component of the Alcohol Help Center, to make the CYD screener more useful to periodic heavy drinkers, as well as to regular alcohol consumers. Participants’ initial reactions to the CYD screener and the changes in their drinking habits at a three-month follow-up are presented. Methods The CYD screener provides a free personalized Final Report that compares the user’s drinking to that of others in the general population of the same age, gender, and country of origin. Current alcohol consumption and demographic characteristics are collected as part of the CYD screening process. After users were presented with a customized Final Report, they were hot-linked to a volunteer feedback survey. The voluntary feedback survey asked about impressions of the CYD Final Report. Respondents agreeing to participate were sent a follow-up survey after three months. Results We recruited 388 volunteers (69% female) who were registered users of another free-to-consumer online eHealth service. Of the 343 respondents agreeing to participate in the three-month follow-up, 138 accessed the survey, and 97 provided complete data (participation rate = 40%; completion rate = 70%). Compared to moderate drinkers, current problem drinkers judged the Final Report to be more useful (34% vs. 69%, χ21 = 41.5, P < .001) and accurate (43% vs. 76%, χ21 = 36.0, P < .001). Respondents who participated in the three-month follow-up displayed reductions in drinking compared to baseline (F4,76 = 12.2, P = .001). Conclusions Improvements can still be made to make the CYD screener more relevant to specific populations, particularly periodic heavy drinkers. There is a need to further tailor algorithms that can present questions only relevant to specific populations. There also appears to be a need to further customize the Final Report for respondents who identify themselves as infrequent heavy drinkers. These improvements will be made, and a randomized controlled trial is planned to conduct a rigorous evaluation of the CYD screener as an intervention to help problem drinkers.

Abstract
The objective of this study was to conduct a preliminary evaluation of an Internet-based intervention for problem drinkers, comparing changes in drinking between respondents who only received the intervention to those who also received a self-help book. After receiving a personalized feedback summary on the Internet, 83 respondents provided complete baseline information and volunteered to participate in a 3-month follow-up survey. Half of the respondents were randomized to receive an additional self-help book. The follow-up was returned by 48 respondents (69% female). Repeated measures ANOVAs were conducted to compare drinking levels at baseline and 3-month follow-up among respondents who only received the Internet-based intervention. There was minimal support for an impact of the Internet intervention alone. In addition, hierarchical regression analyses were conducted to compare respondents in the two intervention conditions on their drinking at follow-up, controlling for baseline consumption. Respondents who received the additional self-help book reported drinking less and experiencing fewer consequences at follow-up as compared to respondents who received only the Internet-based intervention. While the results are promising, they cannot be taken as evidence of the efficacy of Internet-based personalized feedback as a stand-alone intervention because of the absence of a control group that did not receive the intervention. Further research on this topic should be a priority because of the potential for Internet-based interventions to reach problem drinkers underserved by traditional treatment.

Abstract
This study evaluates the impact of a self-help pamphlet designed to support self-control of drinking. It was conducted in Helsinki, Finland, in 2001 and 2002 and focused on men between 30 and 49 years of age. The respondents were randomly selected in an intervention and a control area and compared with each other before and after the intervention using independent samples (N = 4418) The results support previous findings showing that interventions like this serve as a supplement to other prevention and early treatment measures. Although the results were encouraging, there is a need for more in-depth studies in the field.

Abstract
The authors evaluated the efficacy of a computer-delivered personalized normative feedback intervention in reducing alcohol consumption among heavy-drinking college students. Participants included 252 students who were randomly assigned to an intervention or control group following a baseline assessment. Immediately after completing measures of reasons for drinking, perceived norms, and drinking behavior, participants in the intervention condition were provided with computerized information detailing their own drinking behavior, their perceptions of typical student drinking, and actual typical student drinking. Results indicated that normative feedback was effective in changing perceived norms and alcohol consumption at 3- and 6-month follow-up assessments. In addition, the intervention was somewhat more effective at 3-month follow-up among participants who drank more for social reasons.

Abstract
Previous studies have shown that self-help materials can be effective in helping people quit smoking. However, it is not known what proportion of smokers in the general population are interested in this method of cessation. A representative sample of 267 daily smokers participated in a random digit dialing telephone survey. Respondents were asked about their level of interest in self-help materials that would help them quit smoking. Potential predictors of level of interest were examined first through bivariate analyses, followed by a multinomial logistic regression. Of daily smokers, 27% were very interested in receiving a self-help booklet, 28% were somewhat interested, and 45% were not at all interested. Interest in self-help materials was positively related to intent to quit in the next 6 months and to low family income.
