Client Perspectives of Case Stories in Internet-Delivered Cognitive Behavioral Therapy for Public Safety Personnel: Mixed Methods Study.

Background: Internet-delivered cognitive behavioral therapy (ICBT) is an effective and convenient means of offering cognitive behavioral therapy to the general population. To increase access to ICBT among Canadian public safety personnel (PSP)-a group that experiences elevated rates of mental health concerns and barriers to mental health care-a clinical research unit called PSPNET has tailored ICBT to PSP, primarily through offering case stories and PSP-specific examples within an ICBT program. PSPNET's first and most frequently used ICBT program, called the PSP Wellbeing Course, has been found to reduce symptoms of mental disorders (eg, anxiety, depression, and posttraumatic stress) among PSP. Little research, however, has investigated clients' perceptions of the case stories in this course.

Objective: This study was designed to expand the literature on the use and evaluation of case stories in ICBT among PSP. Specifically, this study investigated (1) PSP's perceptions of the case stories using the theoretical model provided by Shaffer and Zikmund-Fisher and (2) PSP feedback on the case stories in the PSP Wellbeing Course.

Methods: This study included 41 clients who completed the PSP Wellbeing Course. Of these, 27 clients completed a bespoke questionnaire called the Stories Questionnaire, 10 of whom also participated in a semistructured interview.

Results: Findings show that perceptions of the case stories in the PSP Wellbeing Course were largely positive and that the case stories were generally successful in achieving the 5 purposes of case stories (ie, informing, comforting, modeling, engaging, and persuading) proposed by Shaffer and Zikmund-Fisher. Client feedback also identified 3 tangible areas for story improvement: characters, content, and delivery. Each area highlights the need for and potential benefits of story development. Not all PSP engaged with the case stories, though, so results must be interpreted with caution.

Conclusions: Overall, this study adds to the growing body of research supporting the use of case stories in internet-delivered interventions among PSP.
