Internet-based cognitive behavioural therapy and association to self-efficacy, depressive symptoms and physical activity: A secondary analysis of a randomized controlled trial in patients with cardiovascular disease (Preprint)

Chronic health conditions and disability are prevalent among community users of a digital mental health service: a scoping survey

Objectives: Digital interventions can offer accessible and scalable treatment for chronic conditions, though often focus separately on physical or mental health. People accessing digital health services may live with multiple conditions or experience overlapping symptoms. This study aimed to describe the breadth and characteristics of chronic health conditions and self-reported disability among routine users of a digital mental health service, and to examine related motivations to engage with digital mental health interventions.

Methods: A cross-sectional survey of adults registered with a digital mental health service in the Australian community (THIS WAY UP) was conducted. Participant demography, chronic health conditions, self-reported disability and motivations for accessing digital treatment were collected and analyzed descriptively.

Results: 366 participants responded (77% female, mean age 50 ± 15 years). 71.6% of participants (242/338) reported ≥1 chronic health condition and one-third reported multimorbidity (112/338, 33.1%). Chronic pain, musculoskeletal and connective tissue disorders were most common. 26.9% of respondents (90/334) reported a disability, most commonly physical disabilities. 95% of those with chronic conditions reported negative mental health effects and 46% reported heightened interest in digital mental health treatments because of their condition. Primary motivations for digital service use were receiving a recommendation from a health professional and service accessibility.

Discussion: People who access digital mental health services in routine care report high rates of heterogenous chronic illness and related disability. There is interest in accessible digital treatments to support mental health at scale among people who live with varied chronic conditions and disabilities.

The effects of internet-based cognitive behaviour therapy for depression in cardiovascular disease on symptoms of anxiety: a secondary analysis of a randomized trial

AIMS

The aims of this study were to evaluate: (i) the short- and long-term effects of the internet-based cognitive behaviour (iCBT) programme on symptoms of distress and fear disorder in cardiovascular disease (CVD) patients, and (ii) the association between changes in depression and changes in symptoms of distress and fear disorder from baseline to 12-month follow-up.

METHODS AND RESULTS

Secondary analysis of data collected in a randomized controlled study evaluating the effects on depression of an iCBT programme compared to an online discussion forum (ODF) in CVD patients (n = 144). Data were collected at baseline, at post-intervention (9 weeks), and at 6- and 12-month follow-ups.The results showed that symptoms of distress disorder were statistically significantly more reduced in the iCBT group than in the ODF group. For symptoms of the fear disorder, no differences were found except for avoidance, which showed a statistically significant reduction in the iCBT group. The long-term analysis in the iCBT group showed that CAQ total score and fear decreased from baseline to 6- and 12-month follow-ups, respectively. Avoidance and attention both decreased statistically significantly from baseline to post-intervention, but not between post-intervention and 12-month follow-up.

CONCLUSION

The results suggest that the iCBT programme targeted depression in CVD patients successfully reduced symptoms of distress disorder and to a lesser extent symptoms of fear disorder. Change in depression was more strongly associated with a change in distress than a change in fear disorder.
