Brief Summary
This study is a two-arm, randomised controlled cross-over feasibility study with a nested, optional qualitative study. The intervention consists of a self-guided smartphone app (Orbi) based on cognitive behavioural therapy (CBT) principles, which is designed to support psychological adjustment in long-term physical conditions. Orbi is an app adaption of an existing, evidence-based web-based intervention COMPASS. The control condition consists of usual charity support (UCS) for the relevant long-term physical health conditions (LTCs). All charity support includes a helpline which can be accessed via telephone or email. The goal of this trial is to evaluate the feasibility of Orbi and the main questions it aims to answer are:
- Be randomised and each participant has an equal (50 %) chance of being assigned either to the Orbi+UCS group or to UCS group alone for 12 weeks. After 12 weeks, they will be crossed over to the alternate condition for another 12 weeks
- Complete questionnaires to assess psychological distress and intervention engagement at baseline, 6 weeks, and 12 weeks.
- A subset of participants will be invited to take part in a nested, optional semi-structured interviews to explore their experiences using Orbi and participating in the study.

Study Arms (2)
Orbi + Usual Charity Support (UCS)
EXPERIMENTALParticipants randomised to this condition receive access to a self-guided smartphone app (Orbi) based on cognitive behavioural therapy principles in addition to Usual Charity Support (Orbi + UCS) to support Psychological Adjustment in long-term physical conditions.
Usual Charity Support (UCS)
NO INTERVENTIONParticipants randomised to this condition access Usual Charity Support (UCS) for their long-term physical condition(s). Resources provided by the charities include supportive listening, online support groups, information resources and local community support groups.
Interventions
Orbi is adapted from COMPASS, a web-based cognitive behavioural therapy (CBT) intervention based on the Transdiagnostic Model of Adjustment in Long-Term (physical) Conditions Model. Orbi is made up of 13 topics, each exploring a different challenge faced by individuals with a LTC(s). Orbi is a self-guided CBT programme with no therapist involvement.
