  1. Note: Max fidelity (100%): Introduction: n=30, OPHI and Ethnographic interview: n = 32, Summary and Goal-setting: n = 34, Consultation and advice: n = 30, Evaluation: n = 16
  2. Components that were N/A are coded as missing and thus scored ‘0’ in percentage calculations, therefore fidelity for individual sets may be underestimated
  3. aThree session 1’s were missing – cannot tell fidelity of these. Can only tell if the observations have been carried out, thus leading to some sets having only 13.3% fidelity. Average without these data points also provided (without a) | b4&5(2) = second Summary and Goal-setting transcript when OTs have delivered 4&5 separately
  4. -: No transcript available
  5. To ensure site anonymity, site numbers have been shuffled up so that numbers 1–15 do not directly correspond to letters A-L
