  1. aPercent of intake patients who established at least one goal or completed establishing a Health Action Plan was operationalized as a measure of two fidelity constructs – content adherence and coverage – because this component was the first component that patients were required to complete in order to proceed with other components of the intervention
  2. bDuration of follow-up is the time from beginning of outreaching till the last successful encounter
