Description of intervention(s) / exposure
People receiving peritoneal dialysis will complete surveys asking about their fatigue and mood experienced at five separate time points per day for a seven-day period using ecological momentary assessment. The time points are; Wake up, bed time and, semi randomly between 10am-1pm, 1pm-4pm and 4pm-7pm. Each survey session should take approximately 5mins to complete.

They will concurrently wear an accelerometer which will collect data relating to their physical activity levels for the same 7-day period.

Secondary outcome [1] 388411 0
Feasibility and Acceptability measured via:
1. Lag-times (i.e. participants’ response time from mobile application prompt to completion of the prompt) and
2. Number of completed prompts
3. A completion survey that was designed specifically for this study, adapted from previous studies, with themes including mobile ease of use, convenience and whether participants consider mobile EMA to have potential to explore other areas of concern for people receiving peritoneal dialysis (e.g. diet, dyspnea, quality of life).

Day after the seven-day period has concluded

Statistical methods / analysis
It is anticipated a recruitment rate of ~50% will be achieved. There are currently 106 eligible people within the clinical catchment. This sample size (n=55) will give ~60% power to detect a moderate effect size and ~90% power to detect a large effect size (EMA tools package R), based on: the number of study days and prompts per day outlined in the procedure above; assuming that, on average, participants will respond to 75% of the prompts; and conservatively estimating that between-subject variability in the momentary experience of fatigue is no higher than 50%.

Descriptive statistics will be used to describe the cohort demographics. Multilevel linear regression modelling will be used to investigate: if fatigue fluctuates throughout the day, with time as the independent variable and fatigue scores as the dependent variable; the temporal associations between fatigue and mood at wake up and subsequent activity levels of the same day (1pm - 7pm); and inversely, the activity levels during the day (10am – 4pm) and subsequent fatigue and mood scores at bed time; the temporal associations between the activity levels in the 30 minutes preceding and following the survey prompt and, fatigue and mood scores at the time of the prompt. Moderate-to-vigorous intensity physical activity levels and total physical activity levels (min)will both be considered in these analyses. All analyses will be adjusted for age, sex. Descriptive statistics will be used to report the quantitative data (e.g. Likert scales) and narrative synthesis for the qualitative elements of the participant feasibility/acceptability survey. Descriptive statistics will further describe the reach (i.e. proportion of eligible participants who agreed to take part in the study); the compliance (i.e. proportion of prompts answered on time by participants and mean lag times); and the proportion of participants who withdrew from the study with narrative synthesis to describe the reasons for withdrawal. Statistical analysis will be completed using Stata Version 16 (StataCorp, College Station, TX) and R Version 3.6.3.

Summary
Brief summary
This research aims to explore the relationships between mood, fatigue and physical activity through the use of a novel mobile application (ecological momentary assessment (mEMA)). mEMA is a survey method that allows data collection of participants’ behaviours, mood and perceptual experiences in real-time (momentary) and in real-life environments (ecological).

Patients receiving peritoneal dialysis will be recruited from within the CNARTS catchment.
This will be a intensive longitudinal observation design. Consenting participants will be met at home or during a routine clinical appointment to assist with download of the mobile app (free to participants) and instruction on correct use of this application. The application will prompt users to answer a set of pre-set questions relating to mood, fatigue at five times each day for seven days. Participants will also be asked to wear a accelerometer for the same seven day period. Accelerometers are highly valid and an objective measure of physical activity levels.

The overarching research aims are to explore in real-time how fatigue levels fluctuate throughout the day, and to investigate the associations between mood and physical activity levels and fatigue in people with ESKD receiving peritoneal dialysis. The secondary aim is to explore the feasibility of using EMA in this population
