Table 3 Suggested intervention content and mechanisms of action using the behaviour change technique (BCT) taxonomy (v1); behaviour change wheel capability, opportunity and motivation-behaviour (COM-B) model; and theoretical domains framework (TDF) [26]
Intervention component | Mechanisms of action | Intervention content | |||
|---|---|---|---|---|---|
TDF1 | COM-B2 | BCT grouping | BCTs | Functions | |
Information and training about immunoglobulin use in primary care, i.e. provide guidelines on when to request and how to interpret results | Kn, MAD, BR | C-(Psy.), C-(Phys.) | Shaping knowledge | Instructions on how to perform behaviour | Education |
Provide feedback on individual GP feedback (volume of tests) Note: not a suitable strategy in this context | Kn, | C-(Psy.) | Feedback and monitoring | Feedback on behaviour | Education, persuasion |
Clearly communicate situations where immunoglobulin testing is not beneficial. (i.e. develop an algorithm of scenarios where tests should be performed, supported by consultant haematologists and GPs) | B Cap, B Con | M-(Refl.) | Natural consequences, comparison of outcomes | Information about health consequences, credible source | Persuasion |
Provide notes detailing consultant advice on the test results (ideally provided on the end of the test results) | Env, S/P Id | O-(Phys.), O-(Soc.) | Antecedents, associations | Restructuring the physical environment, prompts/cues, Adding objects to the environment | Environmental restructure, enablement |
