159 Preventing relapse after successful treatment SE and AK independently analysed the patient data, and SE and JP independently analysed the HCP focus group transcripts. Each step contained several iterations where researchers discussed the meaning of the data as well as how to accurately describe the data in terms of themes and subthemes with respect to the study aims. At the end of this process, the researchers held a final consensus meeting that involved summarizing the data in themes, subthemes, related quotes, and interim conclusions. Although the answers on key questions during the interviews and focus groups were summarized by the interviewer to confirm they sufficiently captured their experience or opinion, participants were not involved in checking the results of the data analysis. RESULTS Demographics During the course of the study, a workbook was offered to 19 patients; 8 patients did not respond to our requests to participate in the telephone survey. Therefore, our final dataset came from a focus group with 4 HCPs, telephone interviews with 11 patients, and in- depth interviews with 2 of these patients. The HCPs were a behavior therapist (male, 19 years’ experience), physiotherapist (male, 5 years’ experience), behavior therapist (female, 14 years’ experience), and occupational therapist (female, 11 years’ experience). Table 1 provides an overview of the patient participant characteristics. Table 1. Overview of Participant Characteristics (n=11). Characteristics Value Female, n (%) 6 (55) Age in years, mean (SD) 55.20 (12.21) Pretreatment level of disability (PDI a ), mean (SD) 35.29 (9.48) Pretreatment level of anxiety (HADS b ), mean (SD) 8.83 (3.55) Pretreatment level of depression (HADS), mean (SD) 8.00 (4.52) Notes: a PDI: Pain Disability Index; b HADS: Hospital Anxiety and Depression Scale. The majority of codes could be clustered within our predefined framework, but we added the theme adaptation for a better fit. This theme covered the extent to which the prototype intervention could be adapted to each patient or whether personal characteristics were required for effective use. Table 2 provides an overview of our final coding scheme.
