Almost 30,000 people in the UK receive dialysis due to end stage renal disease (ESRD). Although dialysis prolongs life, people receiving dialysis are still typically bothered by a range of physical symptoms and need to make substantial adjustments in order to accommodate ESRD and its treatment. One adjustment that is often required is a dramatic reduction in fluid intake. Although sticking to fluid intake restrictions improves the efficiency of dialysis, monitoring fluid intake is complicated. The restrictions also leave people feeling very thirsty so restrictions can be hard to stick to. This project will develop and test a brief psychological intervention for people who struggle to adhere to fluid intake restrictions and will aim to increase quality of life whilst on dialysis. The intervention will be developed with input from people with lived experience of ESRD. It will then be offered to 12 people, recruited from clinics, who will complete questionnaires to monitor experiences and symptoms before, during and after the intervention. Participants' data will be analysed to find out whether the intervention has been helpful in reducing fluid intake and improving quality of life. If the findings are promising, this would suggest that the intervention could be tested in a larger clinical study in the future.
Please note: this study adopts a between-subjects concurrent multiple baseline single case ABC experimental design. Participant change within and across phases A (baseline, variable with participants randomised to a 6, 8, or 10 week baseline), B (4 week intervention phase) and C (4 week follow-up) will be explored.

| Dialysis Diet and Fluid Intake Non-Adherence Questionnaire (Vlamink et al., 2001) | This brief four-item measure assesses adherence to diet and fluid requirements over the previous 14 days. It includes the following items: 1) On how many days during the last 14 didn't you follow your diet guidelines? 2) To what degree did you deviate from your diet guidelines? (0-no deviation to 4 - very severe deviation) 3) On how many days during the last 14 didn't you follow your fluid guidelines? 4) To what degree did you deviate from your fluid guidelines? (0-no deviation to 4 - very severe deviation). | baseline phase week 2 |

This measure assesses severity of clinical symptoms, across 10 items, each rated 0-4. The measure differentiates clinical samples from non-clinical populations. It has adequate convergent validity when correlated with other clinical measures, and good internal reliability (Cronbach's alpha > .80) and sensitivity to change (see Connell & Barkham, 2007). A change on the CORE-10 of six or more points corresponds to statistically reliable change. Scores on the measure are interpreted as follows: 0-5 (healthy); 6-10 (low level); 11-15 (mild); 16-20 (moderate); 21-25 (moderately severe); 26 + (severe). |

| EQ-5D-5L (EuroQuol Group, 2009). | This widely used measure assesses quality of life across five domains: mobility, self-care, usual activities, pain / discomfort, anxiety/depression. Each domain is rated on a five-level scale: no problems, slight problems, moderate problems, severe problems, unable to/extreme problems. Additionally, respondents complete a health thermometer rating their current health status on a scale from 0 to 100. The EQ-5D-5L is a widely used measure for assessing health status with normative data available for UK samples. | Baseline phase week 1 |
