Computerized Interventions

What Can Computers do?

• Deliver audio, text, visualizations
• Automate and tailor feedback
• Minimize in-person contact
• Record and store data
• Interface with other electronic devices

Alcohol & Tobacco Use

• Rooke et al (2010) - meta-analysis of 42 effects sizes from RCTs
• Results: d = .20
• No moderators; location, feedback, "EEs", # sessions/FU, relapse prevention

College Drinking Interventions

• Carey et al (2009) - meta-analysis from 43 "CDIs"
• CDIs reduced quantity & frequency relative to assess-only controls
• ...but rarely differed from comparison conditions incl. alcohol content
• Small-to-medium effects sizes for 6 weeks
• More intensive interventions were occasionally associated w/greater effects

Lee et al (2011)

• Purpose?
• Method?
• Results?
• Conclusions/Implications?

Williams et al (2013)

• Purpose?
• Method?
• Results?
• Conclusions/Implications?

Summary

• Computers can deliver most intervention materials
• Evidence exists for short-term effects
• Longer follow-ups are needed
• "Connectedness" may be important component
