Figures & data

Figure 1. Overview of the co-design process for developing the R&R treatment manual. Note: PMIEs = potentially morally injurious events.

Table 1. Recruitment estimates.

	Expert professional stakeholders	Veteran participants	Veteran patients	Therapist
Stage 1. Exploration of existing evidence
Stage 2. Development and refinement of core treatment features	15	20
Stage 3. Evaluating the treatment and treatment acceptability			20	1

Note: The veteran participants are participants who were interviewed about their views on the treatment features that had been developed in Stage 2. These participants will not be offered the developed treatment from Combat Stress (Stage 3).
