“…For test statistics from ANCOVA results, we followed the conversions in Borenstein (38, Table 12.3). We assumed a partial correlation of 0.50 (42) because the most common covariate was baseline drinking, and estimates of the stability of drinking over time are in the range of r = 0.50 for heavy drinkers followed for at least 3 months (43). In the absence of other data, if the results were presented as statistically “significant,” we calculated an effect size consistent with p = .05 (44).…”

Meta‐analysis of naltrexone and acamprosate for treating alcohol use disorders: when are these medications most helpful?

Aims Although debates over the efficacy of oral naltrexone and acamprosate in treating alcohol use disorders tend to focus on their global efficacy relative to placebo or their efficacy relative to each other, the underlying reality may be more nuanced. This meta-analysis examined when naltrexone and acamprosate are most helpful by testing: (1) the relative efficacy of each medication given its presumed mechanism of action (reducing heavy drinking versus fostering abstinence) and (2) whether different ways of implementing each medication (required abstinence before treatment, detoxification before treatment, goal of treatment, length of treatment, dosage) moderate its effects. Methods A systematic literature search identified 64 randomized, placebo-controlled, English-language clinical trials completed between 1970 and 2009 focused on acamprosate or naltrexone. Results Acamprosate had a significantly larger effect size than naltrexone on the maintenance of abstinence, and naltrexone had a larger effect size than acamprosate on the reduction of heavy drinking and craving. For naltrexone, requiring abstinence before the trial was associated with larger effect sizes for abstinence maintenance and reduced heavy drinking compared to placebo. For acamprosate, detoxification before medication administration was associated with better abstinence outcomes compared to placebo. Conclusions In treatment for alcohol use disorders, acamprosate has been found to be slightly more efficacious in promoting abstinence and naltrexone slightly more efficacious in reducing heavy drinking and craving. Detoxification before treatment or a longer period of required abstinence before treatment is associated with larger medication effects for acamprosate and naltrexone, respectively.

“…More generally, considerable stability in alcohol use or nonuse emerged across time-76% of the sample either never drank from W1 to W6 or had drunk at least something during each wave. But at the same time, change was evident in almost one quarter of the sample, as others have found (Cook and Moore, 2001;Kerr et al, 2002;Webb et al, 1991). Clearly, individual variation is important to consider.…”

ABSTRACT. Objective:We explored patterns of alcohol use among American Indian youths as well as concurrent predictors and developmental outcomes 6 years later. Method: This study used six semi-annual waves of data collected across 3 years from 861 American Indian youths, ages 14-20 initially, from two western tribes. Using a latent Markov model, we examined patterns of change in latent states of adolescent alcohol use in the past 6 months, combining these states of alcohol use into three latent statuses that described patterns of change across the 3 years: abstainers, inconsistent drinkers, and consistent drinkers. We then explored how the latent statuses differed, both initially and in young adulthood (ages 20-26). Results: Both alcohol use and nonuse were quite stable across time, although we also found evidence of change. Despite some rather troubling drinking patterns as teens, especially among consistent drinkers, most of the youths had achieved important tasks of young adulthood. But patterns of use during adolescence were related to greater levels of substance use in young adulthood. Conclusions: Latent Markov modeling provided a useful categorization of alcohol use that more fi nely differentiated those youths who would otherwise have been considered inconsistent drinkers. Findings also suggest that broad-based interventions during adolescence may not be the most important ones; instead, programs targeting later alcohol and other drug use may be a more strategic use of often limited resources.

“…Limitations include the following: the possible inaccuracy of self-reported alcohol consumption (Hilton, 1989;Midanik, 1982Midanik, , 1988Redman et al, 1987;Rehm, 1998;Smith et al, 1990;Webb et al, 1991;Williams et al, 1985); our use of a 1 month recall period to classify typical heavy drinking for a 6 month period of risk for injury; the lack of information to control for personality variables such as sensation seeking and behavioral undercontrol correlated with both risk taking and problem drinking (Cherpitel, 1999); and the lack of information on the drinking history of noncurrent drinkers. Our comparisons between current drinkers and the group of noncurrent drinkers (composed of respondents with an unknown mixture of drinking histories) are therefore difficult to interpret and may be confounded by the association of lifetime abstainers with variables such as religiosity, propensity to avoid deviant behavior, and risk aversion.…”
