McCrady and colleagues ran two studies side by side. One was a randomized trial of behavioral treatment for heavy drinkers who wanted help. The other followed heavy drinkers in the community who weren't looking for treatment at all. Same measures, same follow-up schedule, 15 months of data on both. Both groups ended up drinking less. The real question underneath: how much of that drop needs a therapist, and how much happens on its own?
What they did
The clinical side was an RCT (randomized controlled trial) with 110 heavy drinkers who came looking for help. Everyone got 2 to 4 sessions of motivational enhancement therapy first, then eight sessions of either cognitive behavioral therapy or a mindfulness-based approach. The comparison group was a separate community sample of 190 heavy drinkers recruited for a naturalistic study, no treatment offered.
Both groups reported their drinking with the Timeline Followback, a structured recall interview, at baseline and at 3, 9, and 15 months. The main number was percent heavy drinking days. Frequency of any drinking and drinks per drinking day were secondary.
The two samples weren't recruited the same way, which is a real problem for comparing them. Researchers leaned on two tools to patch it: propensity scores, a statistical way to match the groups on background differences, and latent growth curve models, which fit a curve to how each group's drinking changed over time rather than just comparing endpoints.
What they found
- Both groups cut back over the 15 months.
- The treatment group showed medium to large reductions in heavy drinking and in drinking frequency overall.
- The community group dropped too, but with small effects, and no therapy.
- Cognitive behavioral therapy and the mindfulness approach came out even. No difference on any outcome.
- By the end, the treatment group had drifted down to levels at or below the untreated community sample.
One caveat runs through all of it: because the two samples were recruited differently, the head-to-head is statistically patched rather than clean, so I'd read the size of the gap loosely, not to the decimal.
What it means
The even split between cognitive behavioral therapy and mindfulness is worth sitting with. Two fairly different methods, same result. That fits a pattern I keep running into in this literature: the specific technique often matters less than showing up with a reason to change. An RCT where a digital tool only helped people who'd already set a goal found the same thing from the other direction. Motivation does a lot of the lifting; the packaging does less.
The untreated group is the part I can't stop thinking about. They got no therapy, just a recall interview every few months, and still drifted downward. Some of that is likely regression from a rough baseline, and some is probably measurement reactivity: once someone asks you to count your drinks, you start noticing them. Korean students who simply logged their drinking drank less with no advice attached, which points the same way.
That noticing is the whole idea behind AlcoBalance. On a night out you can see your peak coming and when it fades, so you get to ease off while you're still steering the evening, not reading the damage the next morning. It's not a stand-in for treatment. The people who got therapy here dropped further, and if you're in that boat, professional help clearly pulls more weight. But for the everyday drinker who just wants to feel the wheel in their hands, awareness in the moment is a lever you already own.
