Chronic Physical Health Conditions

Chronic health conditions are common, disabling, and often co-occur with depression and anxiety. Internet-delivered cognitive behaviour therapy (ICBT) reduces barriers to treatment and has been adapted for chronic conditions. A transdiagnostic approach is promising because it is both effective and convenient in that clients with diverse conditions receive the same program. Both therapist-guided and self-guided formats have been found effective; however, in routine care therapist support is most common to ensure that clients have support to personalize care. This study evaluates the therapist-guided Chronic Conditions Course (CCC) and examines predictors of change. Past research shows that the most robust predictors of ICBT outcomes are baseline severity, adherence, credibility, and working alliance. However, few studies of ICBT for chronic conditions have examined predictors together. Moreover, the researchers are aware of no studies that have examined these core predictors in routine delivery of ICBT for those with chronic health conditions alongside other predictors-such as changes in thoughts and adaptive actions. A limitation of past work is that predictor analyses were typically secondary to trials designed for other purposes. This study directly addresses that gap by prospectively modeling predictors of change in routine care.
