  •  The purpose of the study and the research questions
  •  The study design for testing the impact of coaching
  • Application of the multiphase optimization strategy (MOST) framework
  • Systematic evaluation of three dimensions of coaching (dosage of coaching, recipient of coaching, and amount of coach training)
  • Use of a factorial design
  • Requirements for detecting effects and sample size
  • The implementation research component of the study
  • The cost component of the study
  • The measures
  • The important logistical issues and challenges for carrying out this study design
