Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Feasibility and acceptability of the intervention measured by: 1. Recruitment rate measured by screening questionnaire at baseline 2. Completion rate measured by number and stage of withdrawals 3. Qualitative analysis of semi-structured interviews post-intervention or at point of drop-out | — |
Secondary
| Measure | Time frame |
|---|---|
| Estimated effect sizes of changes in secondary outcome variables: 1. Interpretation bias is measured by Ambiguous Scenarios Task at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 2. Severity of fatigue is measured by Chalder Fatigue Scale at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 3. Disability is measured by Work and Social Adjustment Scale (WSAS) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 4. Disability is measured by Short Form-36 Physical Functioning Scale (SF-36) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 5. Depression is measured by Patient Health Questionnaire (PHQ9) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 6. Anxiety is measured by Generalised Anxiety Disorder (GAD7) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 7. Illness related cognitions and behavioural responses measured by Cognitive Behavioural Responses Questionnaire (shortened version) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 8. Acceptance of fatigue is measured by Fatigue Acceptance Questionnaire (FAQ) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 9. Flexible persistence in goal-directed behaviour is measured by Committed Action Questionnaire- short version (CAQ-8) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) 10. Influence of thoughts on actions is measured by the Cognitive Fusion Questionnaire (CFQ) at baseline (T0), post-intervention (T1), 1 month (T2) and 3-months follow-up (T3) | — |
