Table 3 Summary of the systematic selection of theoretical constructs to target in the development of the interventions1.

From: Developing the content of two behavioural interventions: Using theory-based interventions to promote GP management of upper respiratory tract infection without prescribing antibiotics #1

Theoretical Construct Intention Simulated Behaviour Behaviour  
TPB Predictor Y/N r Predictor Y/N r Predictor Y/N r Mapped beliefs that discriminate between GPs who do and do not intend to manage URTI without antibiotics [17]
Attitude direct* Y 0.49 Y 0.32 N 0.07  
Attitude indirect* Y 0.41 Y 0.21 N 0.02  
Intention - - Y 0.44 Y 0.19*  
PBC direct Y -0.28 Y -0.39 N -0.04  
PBC indirect Y 0.60 Y 0.49 N 0.17*  
Subjective norm N 0.04 N 0.005 N -0.10  
SCT        
**Risk perception Y 0.54 Y 0.35 Y 0.17* • Prescribing an antibiotic for these patients will reduce their risk of developing minor complications such as otitis media and sinusitis (BB)
• Because I don't know the cause of these patients' sore throats, I will prescribe an antibiotic so that I don't miss something (CB)
• In most cases, the patient will finish the course of antibiotics I prescribe(CB)
Outcome expectancy (2 items) Y 0.41 Y 0.19 N -0.05  
Outcome expectancy (7 items) Y 0.21 Y 0.27 N -0.03  
Self-efficacy Y 0.56 Y 0.43 Y 0.14* • If a patient asks for an antibiotic then I will prescribe one whether it is medically indicated or not (CB)
• I am more inclined to prescribe an antibiotic for patients of a lower social class (CB)
• Because I don't know the cause of these patients' sore throats, I will prescribe an antibiotic so that I don't miss something (CB)
• In most cases, the patient will finish the course of antibiotics I prescribe (CB)
OLT        
**Anticipated consequences Y 0.54 Y 0.35 Y 0.17* • Prescribing an antibiotic for these patients will reduce their risk of developing minor complications such as otitis media and sinusitis (BB)
• Because I don't know the cause of these patients' sore throats, I will prescribe an antibiotic so that I don't miss something (CB)
• In most cases, the patient will finish the course of antibiotics I prescribe (CB)
Evidence of habitual behaviour Y 0.64 Y 0.46 Y 0.23*  
  1. 1. Data from interim analysis of dataset [25]
  2. * TPB attitudes and PBC constructs can be measured "indirectly" by asking individuals to report their specific beliefs or directly by asking individuals to report at a more general level
  3. **The SCT risk perception questions were also used as a measure of OC anticipated consequences. CB = Control Belief; BB = Behavioural Belief
