Brief Summary

This study is a two-arm, randomised controlled cross-over feasibility study with a nested, optional qualitative study and nested, optional, non-invasive brain activity study. The intervention consists of a self-guided smartphone app (Orbi) based on cognitive behavioural therapy 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 (Hulme et al., 2021; Picariello et al., 2024). The control condition consists of usual charity (UCS) support for the relevant LTC(s). 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:

1. Is Orbi a feasible and acceptable intervention for individuals experiencing psychological distress related to LTCs?

2. Which aspects of the Orbi app and the trial enhance or diminish participants' experience?

Participants will:

* Be randomly assigned to receive Orbi + UCS or UCS alone in a 1:1 allocation ratio, 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.

* A subset of participants will be invited to take part in a nested, optional, non-invasive brain activity study to evaluate potential cognitive changes (e.g. attentional shifts).

Compare post intervention scores on Patient Health Questionnaire Anxiety and Depression (PHQ-ADS-15) adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A 15-item scale assessing symptoms of anxiety and depression. It includes items from the PHQ-8 for depression and the GAD-7 for anxiety, each scored on a 4-point Likert scale from 'not at all' (0) to 'nearly every day' (3). Total scores range from 0 to 45 with higher scores indicating greater symptom severity.

Compare post intervention scores on Patient Health Questionnaire - (PHQ-8) adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

8-item questionnaire scoring the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for depression on 4-point Likert scales from 'not at all' (0) to 'nearly every day' (3). Total scores below 5, 10, 15, 20, and up to 24 are categorised as none-to-minimal, mild, moderate, moderately severe, and severe depression.

Compare post intervention scores on Generalised Anxiety Disorder scale (GAD-7) adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A 7-item questionnaire assessing the severity of generalised anxiety symptoms based on DSM-IV criteria. Each item is scored on a 4-point Likert scale from 'not at all' (0) to 'nearly every day' (3). Total scores range from 0 to 21, with cut-off points at 5, 10, and 15, indicating mild, moderate, and severe anxiety, respectively.

Compare post intervention scores on Illness Related Distress (IRD) scale adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A 14-item scale assessing how a long-term physical health condition has affected the psychological distress experienced by an individual over the last two weeks. The scale is augmented by 3 additional items. Two horizontal visual analogue scales ranging from 0 to 10: One indicating the amount of psychological distress that is attributed to having one or more physical Long Term Condition (LTC) over the last two weeks; one indicating the severity of psychological distress attributable to the LTC over the last two weeks. The final item asks the respondent to specify which LTC they are attributing their psychological distress to (as many people are affected by multiple LTCs in parallel).

Intrapersonal IRD = item 1-7, with cut offs = 15

Interpersonal IRD = item 8-14, with cut offs = 12

Compare post intervention scores on Work and Social Adjustment Scale (WSAS) adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A 5-item scale measuring the impact of mental health issues on daily functioning across work, home management, social leisure, private leisure, and close relationships. Each item is scored from 0 (no impairment) to 8 (severe impairment). Total score ranges from 0 to 40, with higher scores indicating greater functional impairment.

Compare post intervention scores on EQ-5D-3L adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A 5-item scale measuring health-related quality of life across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated on three levels (1 to 3). Total score ranges from 5 to 15, with higher scores indicating more severe issues in health-related quality of life.

Compare post intervention scores on Patient Enablement Instrument (PEI) adjusting for baseline differences between groups6 weeks (mid-study) and 12 weeks (end of study)

A 6-item questionnaire assessing patient enablement (i.e. patients' ability to understand and cope with their health and illness) on a 4-point scale (much better, better, same or less, not applicable). Total scores range from 0 to 12, with higher scores indicating greater patient enablement.

Compare post intervention scores on Patient Global Impression Scales of Severity (PGI-S) adjusting for baseline differences between groupsAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

A one-item questionnaire assessing perceived severity of participants' LTC using a 4-point scale with scoring ranges from 0 to 3. Higher scores indicate greater severity.

Compare post intervention scores on Patient Global Impression of Improvement (PGI-I) adjusting for baseline differences between groups6 weeks (mid-study) and 12 weeks (end of study)

A one-item questionnaire assessing how patient's health condition has changed since the beginning of the study on a 7-point scale with scoring ranges from 0 to 6. Higher scores indicate greater deterioration.

Comparison between intervention and control groups on Health Service UtilisationAt baseline, 6 weeks (mid-study) and 12 weeks (end of study)

Usage of health services will be captured with the Health Service Use Questionnaire. Participants will indicate whether they have accessed key services, including general practice (GP), psychological or counselling services, and emergency care during the past 3 months. For each service reported, additional items capture (i) the number of contacts, (ii) the mode of contact (e.g., in-person, telephone, video), and (iii) the duration of the most recent contact.

Comparision between intervention and control on access of charity services6 weeks (mid-study) and 12 weeks (end of study)

Participants will also be asked about their access of charity resources. A multiple drop box will show the following options (charity helpline, online forums/networks/phone counselling, information booklets, others)
