Measurement Details Timeframe
Practice questionnaire (PPVQ) • Practice capacity for preventive care including use of patient education materials, staff roles and teamwork in preventive care, and linkages between the practice and support services Baseline
GP/PN survey • This survey is based on questions from the Preventive Medicine Attitudes and Activities Questionnaire (PMAAQ) [38], and the Vascular Interventions Survey [39] Baseline & 12 Month
Patient's survey • This survey is based on the NSW Health Survey and previous research [40, 41]. It includes questions about: (1) Practice attendance; (2) reported assessment and management of SNAP risk factors; (3) attendances at other services as a result of referral from the practice or self-referral; (4) self-reported fruit and vegetable intake, smoking, physical activity and alcohol intake, and attempts to change these; (5) readiness for behaviour change (stage of change) for each SNAP risk factor [42]; (6) The Kessler Psychological Distress Scale (K-10), a ten item questionnaire measuring negative emotional states in the preceding four weeks [43]; (7) The Neuroticism Scale from the Eysenck Personality Questionnaire Revised, Short form (EPQ-N-RS) [44], which represents an individual's tendency to experience psychological distress or neuroticism; (8) satisfaction with their care, using the General Practice Assessment Questionnaire (GPAQ) which includes questions in relation to satisfaction with GP and AHP visit and health check [45] Baseline & 6 months & 12 month
Patient's physical assessment • Includes weight, height, BMI, waist circumference and blood pressure measurement.  
Patient's fasting blood tests • Patients are asked to have a fasting blood test to assess their serum lipids (total cholesterol, HDL, LDL, triglycerides) and glucose. Baseline & 12 month
Clinical record audit • Patient records are examined to determine recorded weight, waist circumference, blood pressure, practice attendances during the 12 months of the trial, referral to interventions to address risk factors identified, prescribing of medications (lipid lowering and antihypertensive medications), referrals to dietician, exercise and smoking cessation program. 12 month
GP/PN & IOs interviews • Qualitative interviews are conducted with GPs and PNs in the intervention group and with IOs to explore experience of implementing SNAP risk factor management in routine practice, feasibility and acceptability of brief lifestyle intervention, as well as acceptability and usefulness of referral to support services. 12 month
