Table 2 Criteria used to theoretically sample interviews to include in the analysis

From: An exploration of how clinician attitudes and beliefs influence the implementation of lifestyle risk factor management in primary healthcare: a grounded theory study

Factors related to key categories in the baseline model
Clinicians who scored low1 or high2 on the following attitude items completed as part of a survey at baseline and/or post-intervention:
   • The acceptability of raising risk factor issues with clients
   • Perceived work priority
   • Perceived effectiveness of addressing lifestyle issues
   • Confidence in assessing and managing lifestyle risk factors
   • Confidence in applying behaviour change
   • Perceived accessibility of support services
Other criteria included
   • Clinician types not included in the baseline analysis
   • Clinicians reporting change3 in confidence and/or attitudes from baseline to post-intervention:
   • Clinicians and managers who have recently joined the team (last six months)
Clinician screening and intervention practices
   • Clinicians who had low or high levels of self reported screening for lifestyle risk factors at baseline and/or post-intervention4
   • Clinicians who had low or high levels of self reported intervention for lifestyle risk factors at baseline and/or post-intervention5
   • Clinicians reporting a change3 in screening and or intervention practices from baseline to post-intervention
  1. 1Low defined as scores in the clinician risk factor survey in the lowest quartile for those participating in an interview
  2. 2High defined as scores in the clinician risk factor survey in the highest quartile for those participating in an interview
  3. 3Change defined as scores increasing from lowest to highest quartile or highest to lowest quartile (baseline to post-intervention)
  4. 4High screening practices = mean screening score (across risk factors) in the highest quartile for those participating in an interview, low screening practices = mean screening score in the lowest quartile for those participating in an interview
  5. 5 High intervener = high frequency of intervention for three or more risk factors and/or high intensity intervention (across risk factors), low intensity intervener = low frequency of intervention for three or more risk factors and/or low intensity intervention (across risk factors).
