Self-help Booklets for Depression in Adults With Pulmonary Hypertension.

Previous research has demonstrated high rates of depression in people with pulmonary hypertension (PH). The psychological interventions that support people with depression are not made specific to people with PH and may not be relevant for them, and there is limited evidence examining psychological treatments for depression in people with PH. The aim of this study is to develop and test a self-help psychological intervention for depression based on cognitive behavioural therapy (CBT), which has been developed specifically for individuals with PH. When participants have agreed to take part, they will be allocated at random into an intervention or wait-list group. The self-help materials will be provided online (for people outside of the UK) or posted in paper form (for those living in the UK) and will take four weeks to complete at home. Both groups will complete questionnaires at the same time points (before starting the study, after four weeks and after eight weeks (pre-, post-intervention and one-month follow up). In addition, the intervention group will be contacted after two weeks of their participation and asked about their experiences of the intervention and participation in the study - measuring acceptability of the intervention. The intervention group will also be asked to complete a feedback questionnaire after completing the intervention to further examine acceptability. Analysis will be conducted by the researcher to examine whether the self-help intervention reduced depression in individuals with PH, compared to those with PH who did not receive the intervention. The potential benefit of the study includes a new intervention for depression in people with PH. When the study is completed, if the intervention is found to be helpful and safe, then the people who took part in the study and did not receive the intervention will be offered the intervention.
