Responses were made on a scale that ranged from 0 to 6, where 0 was the lowest and 6 the highest rating, and 3 represented “lagom,” a Swedish term that generally has a positive connotation and means “just right” or “just enough.” The evaluation form included a free-text item where participants could provide additional comments about the study or treatment.All treatment sessions were audio-recorded so that therapists would not know which sessions would be selected to assess their competence in the treatment that they provided and their adherence to the protocol. For each therapist, three recordings of session five were randomly selected for assessment of both competence and adherence. Session five was chosen to ensure that a treatment session was selected. As competence and adherence are somewhat overlapping constructs [Competence in IUT was assessed with the Cognitive Therapy Scale-Revised (CTS-R) [
