Table 4. Constructs predicting intention, implied theoretical domains, and behaviour change techniques.

Constructs predicting intentiona	Relevant theoretical domain37	Behaviour change techniques targeting domain38, 39	Example of intervention tailored to target behaviour
Attitude	Beliefs about consequences	Social and environmental consequences	Facilitator points out expectations of concerned patients for immediate risk assessment and likelihood of greater satisfaction if this occurs.
		Pros and cons	Facilitator asks participants to generate a list of the positive and negative consequences of making a risk assessment during the consultation.
Subjective norm	Social influences	Social comparison	Facilitator asks participants who routinely make a risk assessment in this context to describe a recent example.
		Modelling/demonstrating the behaviour	Facilitator asks participants who routinely make a risk assessment to talk through the factors they consider.
		Social reward	Facilitator congratulates participants on their good practice.
		Vicarious reinforcement	Facilitator congratulates participants who already perform the action on their good practice, in the presence of those who do not.
Perceived behavioural control	Beliefs about capabilities	Verbal persuasion to boost self-efficacy	Facilitator points out that participants often do risk assessment well in other clinical situations, and the similarity of the skills required in this context.
		Focus on past success	Facilitator asks participants to reflect their risk assessment skills in other contexts, then demonstrates the behaviour to illustrate the skills as generic.
	Skills	Graded tasks, behavioural rehearsal/practice	Facilitator provides a template listing key family history information that is taken into account in a risk assessment and in three patient scenarios. Participants complete template to generate risk assessments. Starting with very easy, the three scenarios are of increasing difficulty. The scenarios and decisions are then discussed in break-out groups.
