What does 'dose' mean in the context of program implementation?

• A. The amount of an intervention delivered to participants (e.g., number of sessions, duration, intensity)
• B. Participant's age
• C. Budget spent
• D. Number of staff

Answer: (B)

Dose in program implementation refers to how much of the intervention participants actually receive—the exposure to the program. This includes the number of sessions, the duration of each session, and how intense the delivery is. Measuring dose helps determine whether participants experienced enough of the program to have a potential impact on outcomes and whether the program was implemented as planned. The other items describe different things: age is a participant demographic, budget spent is a financial/resource measure, and the number of staff is a staffing/resource metric. None of these describe the amount of intervention delivered to participants.
