From: Testing the feasibility of a knowledge translation intervention designed to improve chiropractic care for adults with neck pain disorders: study protocol for a pilot cluster-randomized controlled trial

Construct Measure Measurement scale
Feasibility of recruitment, retention, and data completion (both chiropractors and patients) Recruitment and retention rates, missing data Descriptive statistics: mean and SD for continuous variables and proportions for categorical variables
Chiropractor process outcomes   
 Adherence rate Single indicators Continuous data (number of DCs adhering to the intervention per number of eligible participants)
  Composite Count of indicators reaching “success” threshold

Patient health outcomes
