Filter by:This study explores whether giving families a choice of family-based prevention programs to prevent adolescent alcohol use will make a difference in program recruitment, retention, completion, as well as adolescent outcomes. Half of the families are assigned to a traditional random control trial condition and half are assigned to a choice condition. Further, this effectiveness study is being implemented by Kaiser Permanente Health Care system, and explores the issues of implementing such programs within such settings.
This research is designed to assess the impact of pretreatment with puerarin (NPI-031G), a major ingredient in the plant kudzu, on alcohol drinking. Hypothesis: Short-term treatment with this compound will reduce alcohol self-administration in a simulated natural settings laboratory.
To monitor the inhibition of 5a-reductase (5AR) enzyme activity at 1, 3, 7, 14, 21, 28 and 42 days following administration of a single dose of dutasteride (2, 3, or 4 mg) by measuring the change in blood levels of 3a-androstanediol glucuronide (3a-diolG) and the ratio of dihydrotestosterone (DHT) to testosterone. To accomplish this aim, an open-label, between-subjects dose comparison study design will be employed with subjects receiving a 2, 3, or 4 mg dosage. Subjects (up to n=40 enrolled to allow a minimum of 24 completers) will be randomly assigned to one of the 3 dose levels. Results of this study will inform the dose selection for a subsequent placebo-controlled, within-subject, crossover study of dutasteride on the effects of alcohol. A secondary aim of this study is to examine the correlation of a genetic variation in the type I 5AR gene and baseline DHT/T ratio and effect of dutasteride at day 3. A variation in this gene which is one of the targets of dutasteride has been reported to be associated with higher baseline levels of DHT.
This study will determine whether a cognitive behavioral intervention that demonstrates strong evidence in the U.S. of reducing alcohol use is effective when delivered by paraprofessionals in Kenya and compared against a usual care support group.
Several personality factors have been shown to be associated with risk for alcohol and substance misuse, and differentiate substance abusers based on clinical profile, treatment response and susceptibility to other forms of mental illness. Personality-targeted interventions have been found to have significant preventative effects on onset and growth of drinking, binge-drinking and drinking problems in adolescents attending mainstream schools (Conrod, Castellanos & Mackie, 2008). The interventions concurrently reduced personality-specific emotional and behavioural problems (Castellanos & Conrod, 2006), and prevented the onset and escalation of drug-use over a two-year period (Conrod, Castellanos-Ryan & Strang, 2010). This cluster randomised controlled trial aims to examine whether these results can be replicated when interventions are delivered by trained educational professionals. In addition, the trial will evaluate the broader impact of the programme on cigarette smoking, school attendance, academic achievement and school-wide behaviours.
The purpose of the study is to determine whether a web-based ultra-brief intervention, consisting of personalized normative feedback or standardized self-help material, is effective in lowering self reported alcohol use in heavy drinkers.
Purpose of the study: This is a pilot randomized controlled trial to identify methods of involving underage youth in interventions to reduce alcohol use through the primary health care system. The trial will compare the effectiveness of using an onsite behavioral health specialist for screening, intervention and referral with basic written information and staff recommendations typically provided in primary care offices.
This study will explore the hypothesis that effects of alcohol are in part mediated by increased production of neuroactive steroids, which interact with GABAA-receptors. We propose to study non-dependent drinkers using a 4-session within-subjects design in which alcohol / placebo is paired with dutasteride / placebo pretreatment. Dutasteride is a 5-alpha steroid reductase (5AR) inhibitor that limits the production of dihydrotestosterone and the 5a-reduced neuroactive steroids allopregnanolone, pregnanolone and 3a,5a-androstanediol.
310 alcohol abusing or dependent patients beginning intensive outpatient day treatment at community-based clinics will be randomly assigned to one of four conditions: (a) standard treatment as usual (ST) at the clinic without contingency management (CM); (b) standard treatment with contingency management for 12 weeks with a 0.5 probability of winning prizes for each negative sample submitted; (c) standard treatment with contingency management for 24 weeks with a 0.34 probability of winning prizes for each negative sample submitted; or (d) standard treatment with contingency management for 24 weeks with a 0.5 probability of winning prizes for each negative sample submitted. We expect that contingency management will decrease alcohol use to a greater extent than non-contingency management treatment, and that availability of contingency management for 24 weeks may result in longer term benefits than 12 week exposure to contingency management. This study will be the first to evaluate the effects of probability of winning prizes on response to contingency management.
Research has found that natural recovery (self-change) is a very common pathway to change for individuals with alcohol problems, accounting for nearly 75% of recoveries in several national surveys. Although few members of the public are aware that self-change is possible, it also is the case that many individuals with alcohol problems do not enter treatment because of the stigma or fear of being labeled. The proposed study is based on findings from a recent randomized controlled trial designed to promote self-change in the community for problem drinkers who had never been in treatment. Media advertisements were used to recruit 825 participants. Eligible respondents were sent assessment materials to complete. After the assessment materials were returned, participants were randomly assigned to receive two alcohol pamphlets that were freely available in the community or personalized feedback based on their assessment responses (e.g., how their drinking compared to national norms, health risks associated with their drinking). A 1-year follow up found that while there were no differences in drinking behavior between the groups, both groups had very substantial reductions in their drinking 1-year pre- to 1-year post-intervention. In an attempt to determine what accounted for the change, participants' reports of their drinking were evaluated with regard to critical study elements (e. g., when assessment materials were received). Surprisingly, results revealed that many changed after seeing the advertisement, and before receiving the assessment materials to complete. This suggests that either seeing the ad ("Thinking about changing your drinking?") or a message in the ad ("Did you know that 75% of people change their drinking on their own?") may have catalyzed the change. To evaluate when change occurs and the mechanisms that may give rise to change, a randomized controlled trial involving 3 groups will be conducted. The groups will differ in whether they receive a message informing them that self-change is a common phenomenon (two groups will receive the message, one will not) and the occasion when the message is delivered (consenting to the study and before the assessment vs. with the intervention material). Comparisons made possible by the experimental design will allow an evaluation of the message as a precipitant of change. The use of Timeline Followback retrospective reports of daily drinking and recording of critical dates will allow statistical analysis of patterns of inflection (i.e., change in drinking) related to seeing the ad, receiving the message, receiving and completing the assessment materials, and receiving the intervention materials. Possible explanations for how the message could function as a mechanism of behavior change are offered (e.g., catastrophe theory, cognitive social learning theory). The ultimate objective of this research is to develop cost-effective, large scale interventions that can be viewed as an early stage in a public health, stepped care model by encouraging self-change for individuals with alcohol problems.
