Implementation

(Fidelity or Intervention Integrity)

• Identify the potential "implementers" of your intervention and meet with them to gain an understanding of their job duties and competing demands. Conduct formative evaluation to get feedback on how your intervention will fit their usual responsibilities and will fit into the organizational environment. Ask for suggestions to improve the implementation of your program.
  
  Record the extent to which participants and organizational settings complete or make use of various components of your intervention.

• Measure the extent to which agents deliver the intervention as stated in the protocol (e.g., percent of scheduled phone calls completed). If possible, have multiple intervention agents from different backgrounds, levels of training, etc., and document the implementation (and outcome levels) of each agent.
  
  
• Consider in your outcome analyses and conclusions the characteristics of participants who have higher versus lower levels of program use.
