Brief alcohol interventions (BI) are effective for individuals with alcohol dependence, not just those without. This study found that alcohol dependence did not predict less benefit from BI in primary care settings.
Area of Science:
- Public Health
- Addiction Medicine
- Behavioral Science
Background:
- Randomized trials often exclude individuals with alcohol dependence from brief intervention (BI) studies.
- The effectiveness of BI for those with alcohol dependence remains under-examined.
Purpose of the Study:
- To determine if alcohol dependence diagnosis predicts differential effectiveness of primary care-based BI.
- To analyze the impact of BI on alcohol consumption in dependent versus nondependent individuals.
Main Methods:
- Retrospective analysis of 326 participants from a randomized trial on interactive voice response post-BI.
- Collected daily consumption data using Timeline Followback for 6 months pre- and post-BI.
- Compared alcohol consumption outcomes between dependent and nondependent participants.
Main Results:
- Dependent participants showed higher pre-BI consumption but significant reductions in drinks per week and drinking days post-BI.
- Dependent individuals also reduced drinks per drinking day, eliminating group differences post-intervention.
- Both groups showed sustained reductions at 6 months, with dependent participants drinking more on fewer days.
Conclusions:
- No evidence suggests that individuals with alcohol dependence benefit less from BI compared to nondependent individuals.
- Brief interventions delivered by primary care providers appear effective across the spectrum of alcohol use disorders.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
