Transdiagnostic, internet-delivered cognitive behavior therapy for depression and anxiety: Exploring impact on health anxiety.

Health anxiety is associated with significant personal distress and economic cost; as such, widely available and effective treatment options are crucial. Several studies suggest that Internet-delivered cognitive behavior therapy (ICBT) programs that specifically target health anxiety are efficacious for this condition. However, no known studies have examined the impact of transdiagnostic ICBT, which emphasizes the acquisition of broad coping skills applicable to a variety of mental health concerns, on symptoms of health anxiety. The current study sought to explore changes in health anxiety symptoms by utilizing data available from a previously published study of 8-week transdiagnostic ICBT. Specifically, changes in symptoms of health anxiety in response to a transdiagnostic ICBT program that targeted broad symptoms of depression and anxiety, were examined in a subsample of individuals who endorsed elevated symptom scores on the Short Health Anxiety Inventory at pre-treatment (n = 72). Following treatment, large reductions in health anxiety symptoms (Cohen's d = 0.91; 20% improvement), depression (Cohen's d = 0.85; reduction = 38%), generalized anxiety (Cohen's d = 1.21; reduction = 42%), and disability (Cohen's d = 0.90; reduction = 35%) were reported. Furthermore, results showed that transdiagnostic ICBT was rated as acceptable to people with high health anxiety symptoms. Despite elevated pre-treatment health anxiety scores, email correspondence between clients and their therapist revealed very few mentions of health anxiety. These findings provide preliminary evidence for transdiagnostic ICBT for symptoms of health anxiety and suggest further research is warranted.

Content of client emails in internet-delivered cognitive behaviour therapy: A comparison between two trials and relationship to client outcome.

Many Internet-delivered cognitive behavioural therapy (ICBT) programs include email communication between clients and therapists as a part of treatment; yet relatively little is known about the nature and impact of this communication. Previous research conducted by Svartvatten et al. (2015) has identified 10 themes in written correspondence by clients accessing ICBT for depression. The current study examined: (1) if previously identified themes in client emails would be present in a shorter ICBT program for depression and anxiety; and (2) whether themes in emails similarly correlated with symptom improvement, lesson completion, and perceptions of working alliance. Using 80 randomly selected clients from a published ICBT trial (ISRCTN42729166; Hadjistavropoulos et al., 2016), client emails (average 5.69 per client) were examined for the presence of the themes reported by Svartvatten et al. (2015) and correlated with symptom improvement, lesson completion, perceptions of working alliance. Although most themes developed by Svartvatten et al. (2015) were identified in client emails, the frequency of themes differed between studies. Most notably, emails in the current study were more often coded as involving alliance bolstering (~39% vs. 22% of statements) and identification of patterns and problem behaviours (~25% vs. 6% of statements). Greater frequency of tries alternative behaviour and identifies patterns and problem behaviours were correlated with a greater number of lessons completed. In terms of symptom change, greater frequency of maladaptive repetitive thinking and problems with treatment content in the emails were correlated with smaller improvements in anxiety, whereas observes positive consequences was correlated with larger improvements in anxiety. Similarly, greater frequency of maladaptive repetitive thinking was correlated with smaller improvements in depression. Regarding perceptions of working alliance, more frequent statements of observes positive consequences was correlated with higher alliance. The research provides clinicians and researchers with an improved understanding of the comparability and meaning of client communication in different ICBT programs. Experimental research is needed to better understand the role of client communication in ICBT.

Educating patients about Internet-delivered cognitive behaviour therapy: Perceptions among treatment seekers and non-treatment seekers before and after viewing an educational video.

Internet-delivered cognitive behaviour therapy (ICBT) is an efficacious, yet novel approach to the treatment of depression and anxiety. It has the potential to improve access to evidenced-based care, but only if potential patients are aware of, understand, and have positive expectations about this treatment. In order to establish whether the use of an educational video could improve favourable expectations of ICBT, two studies were conducted. The goal of the first study was to determine whether an educational video would improve perceptions of ICBT among individuals seeking ICBT treatment and to determine what type of information (client testimonials versus statistical information related to outcomes) facilitates the greatest increase in positive expectations of ICBT. Participants who visited an ICBT service (N = 71) website were invited to first complete brief questionnaires assessing initial perceptions of ICBT. They were then randomly assigned to watch one of two videos containing either client testimonials (n = 32) or statistical information related to outcomes (n = 39). Patient perceptions of ICBT were then reassessed. Perceptions of ICBT were significantly higher post-video than pre-video and the type of information did not impact perceptions of ICBT. In the second study, the research was extended by examining perceptions of ICBT before and after watching an educational video (including both statistical and narrative information as this had no impact on perceptions) in a sample of individuals (N = 94) who were experiencing anxiety and depression but were not specifically seeking ICBT. As with treatment seekers, perceptions of ICBT were significantly higher post-video than pre-video. Comparison of the treatment and non-treatment seekers revealed no differences in perceptions of ICBT between the samples. The findings suggest that educational videos are an effective way to increase expectations of ICBT. Future directions for research are described.
