Intervention characteristics
CBT (PE via HBT)
Planned number of intervention sessions: 12 to 15 Mode of delivery (face‐to‐face, online, video, telephone, blend, with explanation): teleconference (video/audio) Format (group, individual, blend): individual Therapist qualifications and training appropriate (yes, no, unclear, with explanation): unclear, no information given Research allegiance or conflict of interest (yes, no, unclear, with explanation): no, team is committed to establishing if HBT delivery brings benefits and has used the technology in several other trials, but there is no clear evidence of a conflict of interest. Treatment fidelity (yes, no, unclear, with explanation): no, information not given Intervention aim and theoretical basis: PE is a manualised treatment (Foa 2007) that includes the following components: 1) psychoeducation and treatment rationale (Sessions 1 and 2); 2) repeated in vivo exposure to traumatic stimuli (in vivo exercises are assigned as homework during Sessions 3 through 11); 3) repeated, prolonged, imaginal exposure to traumatic memories (imaginal exposure is implemented during Sessions 3 through 11, and participants listen to session audiotapes for homework between sessions), and 4) relapse prevention strategies and further treatment planning (Session 12). Duration of intervention: 12 weeks to 15 weeks
CBT (PE via in‐person)
Planned number of intervention sessions: 12 to 15 Mode of delivery (face‐to‐face, online, video, telephone, blend, with explanation): face‐to‐face Format (group, individual, blend): individual Therapist qualifications and training appropriate (yes, no, unclear, with explanation): unclear, no information given Research allegiance or conflict of interest (yes, no, unclear, with explanation): no Treatment fidelity (yes, no, unclear, with explanation): unclear, no information given Intervention aim and theoretical basis: in the case of women with a history of MST, accessibility will be enhanced by removing a barrier to care associated with the treatment environment that can potentially elicit an anxiety and avoidance response in the target population. HBT care is delivered using via Movi/Jabber software packages installed on standard tablet devices or home computers with standard internet connections to teleconference (video and audio) in real time. Duration of intervention: 12 weeks to 15 weeks
