Moderate drinking redux; also more on the Sinclair Method

Let me just post some of my recent disqus postings:

The fact is that the Sobell 1973 study [a study which claimed alcoholics could moderately drink again] was so bad, a fraud investigation was opened. As a 1984 New York Times article put it (look for “Panel finds no fraud by alcohol researchers”):

>>The panel also said it had found ''several errors'' and ''use of ambiguous terminology'' in scientific publications by the Sobells, which indicated that they were ''careless in preparing their manuscripts for publication.'' But the panel said it had seen no evidence that these errors and ambiguities ''represent scientific misconduct - defined as 'fraudulent or highly irregular research practices.' ''<<

Anyway, facts are facts. Those “moderate” drinkers from the Sobell 1973 study were either drinking alcoholically again, or were dead from drinking, or were abstaining from alcohol when a 10-year-followup was performed.

Sobell 1973 and the moderate drinkers: Four of those “moderate drinkers” died. Also: Six were abstinent, nine of the “moderate” drinkers were engaging in out of control drinking. There was only one person who, ten years later, could be considered a “moderate” drinker. Please read Pendery 1982 or any of the numerous books which correctly cite it.

Sobell 1973 in comparison to the non-moderate drinkers: This is cherry picking data. The Sobells only compared the fatalities of the “moderate” drinkers with the non-moderate drinkers. I have not seen the abstinent or out-of-control drinking figures for this other group; and it is telling that the Sobells never shared (or, it would seem, even bother to get) those figures.

Since there were only 20 subjects in each study, whether six or four died is an error of approximation, nothing more.

Davies 1962: These “moderate” drinkers also reverted to serious drinking again. Reference: G. Edwards. "D.L. Davies and 'Normal drinking in recovered alcohol addicts': the genesis of a paper" Drug and Alcohol Dependence 35.3 (1994)

Rand report: The 1980 four-year followup shows many of the 1976 Rand report moderate drinkers relapsing.

Moderation management: No peer-reviewed science was ever done with this group, but it’s very telling that its founder drank heavily, to the point police took her to detox in handcuffs while she was still the leader of Moderation Management. She soon afterwards killed two people while driving drunk and eventually killed herself [1].

Point being, pretty much any study showing successful “moderate” drinking, when followed up, shows those same “moderate” drinkers drinking heavily again.

[1] There are claims that the Moderation Management founder was a member of AA at the time of her crash, but as per her autobiography, she did not work the 12-step program in any meaningful way. Instead, she was coming up with excuses for not going to meetings.

In response to a claim that the “moderate” drinkers in Sobell 1973 had better success rates than people trying abstinence:

In terms of more recent studies, people who choose to work the AA program have between a 75% (Vaillant 1995) and 67% (Moos and Moos 2006) success rate. The Sobell moderation group had, by comparison, a 30% abstinence success rate and a 5% moderation success rate.

In response to a claim that the Sinclair method works better when trying complete abstinence, and works better the longer it is applied:

OK, let me go back to PMC3970823. They use a ”magic number” called “g” which is summarized near the end: “the aggregated Hedges’ g for naltrexone and acamprosate compared to placebo was 0.209 (CI: 0.157 – 0.262) – indicating a small but significant effect. In comparison to other medications prescribed for mental health (e.g., for depression), the effects of naltrexone and acamprosate are somewhat smaller”

So, this information in mind, let’s look at table 2 in PMC3970823. Naltrexone has an abstinence aggregate of .116—which is not very different than a placebo. However, the numbers for “heavy drinking” (.189), craving (.144), and both heavy drinking and craving (.180) are not much better—they are “small but significant.”

It also looks like, when looking at multiple studies, the effect diminishes when doing follow-ups: “naltrexone studies tended to have effect sizes for heavy drinking outcomes at the last follow-up point (g = .135, k = 6) that were slightly smaller compared to end-of-treatment (g = .189, k = 39). Although only two studies provided data, the naltrexone-placebo effect sizes for craving at the last follow-up point were close to zero (g = .053).” In other words, this meta-study didn’t see naltrexone helping people not drink heavily over longer periods.

In light of Pendery 1982, and in light of what happened with the founder of Moderation Management (while she claimed to drink moderately without problem for years, she killed two people while driving drunk, and eventually killed herself), when people suggest moderation as an outcome for alcoholics, I will remain very very skeptical until when and if we have 10-year-followups with very high “g” values and very low “p” values.
