Internet-based self-assessment of drinking--3-month follow-up data.

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.

Current heavy drinkers' reasons for considering change: results from a natural history general population survey.

Current heavy drinkers were recruited from a general population random-digit dialing telephone survey. Comparisons were made between those who were considering or not considering change. Those considering reducing or quitting their drinking in the next 6 months were asked their reasons for considering change. Respondents considering change had more severe alcohol problems and perceived more risk associated with their drinking as compared with those not considering change. The most common reasons for considering change were health and financial concerns.

Motivation and life events: a prospective natural history pilot study of problem drinkers in the community.

A prospective natural history study was conducted of problem drinkers who were thinking about quitting or reducing their alcohol consumption. Two primary constructs, cognitive appraisals and life events, were measured in a mailed-out baseline survey. A one-year follow-up survey identified those who had made reductions in drinking. Partial correlations controlling for baseline drinking severity revealed some support for both cognitive appraisal and life events explanations of change.

Internet and paper self-help materials for problem drinking: is there an additive effect?

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.

The impact of a self-help pamphlet on reducing risk drinking among 30- to 49-year-old men in Helsinki, Finland.

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.

Treating alcohol problems with self-help materials: a population study.

OBJECTIVE: An experimental trial was used to assess the effectiveness of a self-help book and a personalized assessment-feedback intervention, both separately and in combination with each other, in a general population survey. METHOD: Participants (N = 86; 66.3% male) were recruited through a random digit dialing telephone survey conducted by the Centre for Addiction and Mental Health, Toronto, Ontario, Canada. Respondents were randomly assigned to one of four conditions in a two-by-two factorial design: "no-intervention" control group, "personalized feedback only," "self-help book only" and "both personalized feedback and self-help book." Respondents were followed up in 6 months' time, and differences in drinking status were compared between experimental conditions using a multivariate analysis of covariance with baseline drinking severity as the covariate. RESULTS: Support was provided for an interaction hypothesis in which respondents who received both interventions reported significantly improved drinking outcomes at 6-month follow-up, compared with respondents who received just one of the interventions or who received no intervention. CONCLUSIONS: Because respondents were recruited from a representative sample of the general population into a randomized trial with a no-intervention control group, this research design maximized both external and internal validity in examining the effectiveness of self-help interventions.
