Study Participants
psychiatric
Two types of participants were included in the study: (1) implementers, that is, local staff who facilitated the implementation of the iCBT service, and (2) mental health service providers such as therapists who were involved in iCBT service delivery.For each of the 12 organizations, a team of up to 5 staff members was appointed as implementers. One team member was appointed as the implementation lead and coordinated the work. Implementers were directly involved in the development, coordination, and execution of local implementation activities such as designing and distributing iCBT information leaflets or developing training materials for referrers and therapists. Implementers were not required to have prior experience in, or specialist knowledge of, implementing iCBT services, but were expected to have working knowledge of the service they were implementing. Implementers could have different functions or roles in the organization, that is, manager, researcher, or clinician. Implementers were expected to have a proficient command of the English language to be able to use the ItFits-toolkit.Mental health service providers were eligible to be included if they had a distinct role in delivering iCBT to patients, including clinicians, psychologists, GPs, psychiatrists, psychiatric nurses, staff in a supporting role (eg, administrators), or IT professionals involved in the operation of the technical aspects of the iCBT services.Local research teams recruited both implementers and service providers with the support of a central research team overseeing the trial. To avoid contamination between the implementation team and the target population of the toolkit, participants could not act as both implementers and service providers.
