Participants and setting
This study examined qualitative data collected within the Stay Strong app through the WICKD clinical trial (ACTRN12617000249358). The trial methods have been detailed elsewhere and are summarised here for context (38).
This three-arm, waitlist, single-blind randomised controlled trial tested the efficacy of the Stay Strong App intervention in improving wellbeing among First Nations people undergoing haemodialysis for ESKD in Alice Springs and Darwin. Participants were randomised to three treatment conditions. One condition (‘immediate treatment’) received the AIMhi Stay Strong app at baseline and at three months, and the other two conditions (‘contact control/delayed treatment’ and ‘usual care/delayed treatment’) received the app at 3 months. Outcome measures were completed at baseline, 3 months and 6 months (36). Participants were reimbursed for their time with a supermarket voucher at each follow up point. In addition to their allocated treatment, all participants received usual care from their renal service.
Participants were Aboriginal and Torres Strait Islander Australians aged ≥18 years, receiving maintenance haemodialysis in Alice Springs or Darwin for more than 6 months. Exclusion criteria were an age <18 years, having visual impairment, a current a guardianship order or being otherwise unable to provide informed consent. Participants were recruited into the study whilst attending their usual dialysis care services. Given that they had received dialysis for at least 6 months, it could be anticipated that the initial impact of this life change had settled to some extent. Participants were nevertheless likely to be active in attempting to identify new self-management strategies given the desire to maintain their health and to prepare for a renal transplant (39). However, many were also likely to have a range of mental or physical health issues including low energy.
As expected, baseline symptoms of depression and distress were common, with 45% (70/156) of participants scoring in the moderate/severe range on the chosen depression screening tool, the Patient Health Questionnaire-9 (i.e. > = 10) and 39% (61/156) scoring in the moderate/severe range on the chosen emotional distress scale, the Kessler 10 (i.e. > = 25) (36). Consistent with the high mortality and morbidity experienced amongst the dialysis population, nine participants died during the study for reasons unrelated to the trial, and two were withdrawn due to being too ill to participate.
Consent, ethics and funding
Approvals were granted by the Central Australian Human Research Ethics Committee (CAHREC No: HREC-16-406) and the Human Research Ethics Committee (HREC) for the NT Department of Health and Menzies School of Health Research (HREC-16-2599), including an Aboriginal subcommittee. Fully informed oral consent was obtained from all participants using pictorial information sheets and flipcharts in plain English with Aboriginal language versions available. Demographic information and outcome measures were collected using a tablet device including pictorial prompts and Aboriginal language recordings (choice of 11 NT languages). Interpreters were used where necessary. This study was supported by the National Health and Medical Research Council (NHMRC) project grant (GNT# 1098311).
Data collection
The intervention
The Stay Strong intervention was delivered by a team of 15 researchers based in Alice Springs and Darwin (13 female, 2male). Eight (53%) had clinical qualifications (occupational therapy, nursing, Aboriginal Health Worker, psychology and naturopathy), and eight (53%) were First Nations people. Following Stay Strong training, the intervention was delivered in teams of two (one non-indigenous and one First Nations researcher), consistent with the AIMhi Stay Strong Planning Brief Treatment Manual [22]. Reviews of app data and ongoing booster training sessions provided feedback to these researchers, allowing adjustment to their mode of delivery as needed [17]. The researchers were not involved in participant treatment and most had not met the participants prior to recruitment to the trial. The interviews were usually held in dialysis waiting areas or homes or hostels, while for a few the intervention was delivered during dialysis.
The Stay Strong app brief intervention, designed to be delivered as a 20-minute session, embodies key elements of a face-to-face semi-structured interview. It incorporates a series of prompt points: family (who supports you?), strengths (what keeps you well?), worries (what takes your strength away?), and strategies for change goals/needs (what goal for change would you like to make and why would that be a good change?).
Each of the prompt points is supported by colourful representative images with twelve choices each for strengths and worries organised under four categories, with the option to add others as desired (Table 1). The chosen prompts, text and images were codesigned with First Nations people and adapted with First Nations and non-Indigenous renal service providers prior to the trial (35). At each step of the session, responses were entered concurrently, allowing the participant to guide the input of their data during the session. Motivation was enhanced through direct comparison between strengths and worries. This promoted discrepancy, a key element of motivational interviewing (40).

The interview was designed to assist in establishment of rapport through sitting side-by-side to view the shared screen, thus avoiding direct eye contact if preferred. A further design element to strengthen therapeutic alliance was the discussion of relationship and strengths prior to exploration of concerns. In addition, the training emphasised that direct questions can be experienced as challenging. Instead, practitioners were encouraged to show the relevant images and simply ask, for example ‘Are any of these worries for you?’.
The training also taught the importance of setting goals which were specific, measurable, accessible, relevant and timely (SMART), in line with recommendations in the literature (41, 42). It highlighted that to maximise motivation the participant was to choose their own goals, while the role of the researcher/therapist was to facilitate their decision making rather than to mould it. The app supported successful goal setting through exploring steps to the goal, covering what would be done, when it would be done and who might support that step. A maximum of two goals was encouraged during each session. At goals review, feedback about progress was given and previous goals might be kept, revised, or replaced. The session concluded with development of a pictorial summary which was reviewed prior to completion. The summary was then printed and delivered to the participant. The review of the plan and delivery of the personal summary was designed to enhance motivation, whilst also allowing participants to review their inputted information.
The delivery of the treatment in the WICKD trial involved an interview of approximately 20 mins using the AIMhi Stay Strong app, with a second session of the same length within 2-4 weeks that was also guided by the app. Session 1 explored family, strengths, worries and goal setting. Session 2 reviewed information entered previously, refined the goals and addressed any barriers to goal attainment, setting new goals as appropriate. Participants received a text message or phone call one week following the initial treatment reminding them of their goals and steps for making changes.
Data analysis
Qualitative data from app sessions were analysed using a combined content analysis and thematic analysis approach, guided by Graneheim and Ludman (43). The initial identified unit of analysis was each individual response to the goal setting section of the interview. This section explored goals for change and reasons for making that change. These responses were recorded in the app and later uploaded to the study data base. Prior to analysis the data set was reviewed, and goals that were repeated in later sessions were removed so that each goal was only included once. Using a deductive approach to manifest content, 13 categories were identified, and their frequency was counted (Figure 1). In a subsequent step, an inductive approach allowed identification of broader themes. Categories and themes were first discussed between the Senior Cultural consultant (PJM) and TN (psychiatrist and senior principal research fellow) and were then checked with research colleagues (MS and KD) until consensus was reached. Opportunity for participant checking occurred during the session, at the review of the app summary at the end of the session, and at the time of sharing the printed summary from the session.
