Thoughts on Collaborative Activities

• Divide ideas into domain-specific and nonspecific
  suggestions
• Consider cross-site measures of both process
  (mediational) and outcome
• Quantify projects focus on environmental and
  intra-personal change and relate nature of focus
  to effect size of interventions
• Consider adding measures to assess effects of
  interventions on implicit as well as explicit
  cognitive processes
