Summary
Web-based personalized normative feedback (WPNF) effectively reduced heavy drinking in college students. This intervention showed greater reductions in drinking quantity and frequency compared to web-based education.
Area of Science:
- Behavioral Science
- Public Health
- Digital Health
Background:
- College students are a demographic at high risk for heavy alcohol consumption.
- Mandated interventions are often necessary for students with alcohol-related issues.
- Web-based interventions offer scalable solutions for reaching college populations.
Purpose of the Study:
- To evaluate the efficacy of two web-based interventions for reducing heavy drinking among mandated college students.
- To compare a web-based personalized normative feedback (WPNF) approach against a web-based education (WE) control condition.
- To investigate the role of perceived peer drinking norms in mediating intervention effects.
Main Methods:
- Random assignment of mandated college students to either WPNF or WE conditions.
- Assessment of drinking behaviors (quantity, peak consumption, frequency) and alcohol-related problems at baseline and 30-day follow-up.
- Measurement of perceived peer drinking norms at baseline and follow-up.
Main Results:
- Students in the WPNF group reported significantly greater reductions in weekly drinking quantity, peak consumption, and frequency of intoxication compared to the WE group.
- The WPNF group showed significantly greater reductions in estimates of peer drinking.
- Reductions in perceived peer drinking norms mediated the intervention's effect on drinking behavior changes.
Conclusions:
- Web-based personalized normative feedback is an effective intervention for reducing heavy drinking in mandated college students.
- Modifying perceptions of peer drinking norms is a key mechanism for reducing alcohol consumption in this population.
- Digital health interventions show promise for addressing college student alcohol misuse.

02:31Protection of Alcohols
This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

02:23Alcohols from Carbonyl Compounds: Reduction
Reduction is a simple strategy to convert a carbonyl group to a hydroxyl group. The three major pathways to reduce carbonyls to alcohols are catalytic hydrogenation, hydride reduction, and borane 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...

01:27CNS Depressants: Alcohol and Nicotine
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
02:15Preparation of Alcohols via Addition Reactions
Overview
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

01:30Community Based Intervention
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
