Description of intervention(s) / exposure
This study is to test the administration of the EQ-5D-Y proxy survey adapted for children aged 2-4 years involving the prospective data collection of several paediatric health related quality of life (HRQoL) instruments (including the EQ-5D-Y proxy survey adapted for children aged 2-4 years) via two surveys completed by the caregiver (proxy), an initial 15-30-minute survey and a retest follow-up 5 minute survey 2-8 weeks later.

The initial survey will include the following questionnaires: Informed Consent, Demographic Information, Carer Quality of Life (EQ-HWB), Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory (PedsQL), Toddler and Infant Health Related Quality of Life (TANDI), EQ-5D-Y adapted (3L and 5L), EQ-5D-Y VAS, Child Health Utility (CHU9D), Global Health Measure, Health Utilities Index (HUI2/3) and relevant disease-specific questionnaires: Asthma PedsQL, KIDSCREEN-27: Health Questionnaire for Children and Young People, Sleep disturbances Scale For Children (SDSC), Child Perceptions Questionnaire (CPQ), Revised Child Anxiety and Depression Scale 25 (RCADS-25), ADHD-Symptoms and Normal-Behaviors (SWAN). Participants will also be asked to report the difficulty of each instrument.

The follow-up survey will include: PedsQL, TANDI, EQ-5D-Y adapted (3L and 5L), EQ-5D-Y VAS, CHU9D and Global Health Measure. Participants will also be asked to report the difficulty of each instrument.

The performance of the adapted survey will be compared to that of the Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL. Instruments will be assessed in terms of acceptability, feasibility, reliability, validity and sensitivity within the Australian context.

Caregivers of children will primarily be recruited by research assistants who will approach families face-to-face in waiting areas across the hospital and ask caregivers to complete the initial survey on an iPad or their own device (will be provided a QR code or text a link on the spot). Some participants will also be recruited via social media adverts, adverts on the virtual telehealth waiting room, or via online survey panels, these participants will complete the survey online via REDcap. The follow-up survey will be delivered online.

Participants may be enrolled into both the Quality of Kids' Lives Study and this study. The same specific disease subgroups will be assessed for this study.

Comparator / control treatment
The performance of instruments will be compared by child age and disease groups. Disease groups (Hospital sample, ADHD sample, anxiety or depression sample, ASD sample, asthma sample, dental decay sample and sleep problems sample) will be compared with well children (as defined by parent report of child health condition(s) in the demographic section of the initial survey).
Control group
Active

Outcomes
Primary outcome [1] 327045 0
Validity (the degree to which the HRQoL instrument measures the construct(s) it purports to measure) of the new adapted instrument compared to other pediatric HRQoL instruments (Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL). Validity of instruments will be measured using within-scale analysis (measured using factor analysis), known group differences (measured by descriptively comparing a priori assumptions regarding expected differences between disease groups and healthy children), convergent validity (measured by analysing the correlation of similar constructs from different instruments hypothesised to measure similar constructs) and discriminant validity (measured by analysing whether dimension responses are independent of child age).
Timepoint [1] 327045 0
Both initial and follow-up surveys.
Primary outcome [2] 327046 0
Consistency (the degree to which the summary and dimension specific responses on each instrument are consistent with dimension and summary responses of other similar instruments) of the new adapted measure compared to other pediatric HRQoL instruments (Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL). Consistency of instruments will be assessed by comparing the consistency of summary and dimension specific responses on each instrument.
Timepoint [2] 327046 0
Both initial and follow-up surveys.
Primary outcome [3] 327047 0
Acceptability and feasibility (composite primary outcome) of new adapted measure compared to other pediatric HRQoL instruments (Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL). Acceptability and feasibility of instruments will be measured by assessing the time to complete instruments (measured using web analytics), completeness of data (measured by analysing data missingness) and reported difficulty (measured by survey question asking participants to report how difficult instrument was to complete, a single item question designed specifically for this study).
Timepoint [3] 327047 0
Both initial and follow-up surveys.
Secondary outcome [1] 394833 0
Primary outcome: Reliability (the stability of the instrument) of the new adapted instrument compared to other paediatric HRQoL instruments (Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL). Reliability of instruments will be assessed using test-retest reliability, measured by agreement on dimension-level responses between the initial survey to the re-test survey 2-8 weeks later.
Timepoint [1] 394833 0
Both initial and follow-up surveys.
Secondary outcome [2] 394834 0
Primary outcome: Responsiveness (the ability of an instrument to detect change in the construct to be measured) of the new adapted measure compared to other pediatric HRQoL instruments (Global Health Measure, TANDI, CHU9D, HUI2/3 and PedsQL). Responsiveness of instruments will be assessed using dimension level responses from children whose proxy respondents reported a change in general status from the initial survey to the re-test survey 2-8 weeks later in comparison to those not showing a change. This will be assessed to determine the extent to which instruments are responsive to change in general status.
Timepoint [2] 394834 0
Both initial and follow-up surveys.

Statistical methods / analysis
Performance will be analysed and compared at summary, dimension and item levels using psychometric analyses. Additionally, the feasibility, acceptability and responsiveness of the various instruments will be compared.

Sample size calculation has not been performed due to a lack of data available to inform how expected responses are likely to be distributed or compare to other QoL measures. We considered it more important to ensure a heterogenous sample in child/family characteristics and in child health-related quality of life. This diversity in the sample is important to determine the validity and applicability of the HRQoL instruments to groups of children. We had considered a smaller sample size which would have allowed for shorter study period and smaller budget, however we settled on 400 participants to ensure the rigor needed for the analyses.
