Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A comic-enhanced version of the standard Participant Information Sheet for the parent CARE study (CAREtoon PIS), is the intervention in the sub-study. This is a modified version of the standard Participant Information Sheet (PIS) documents for the CARE study, which begin with a 2-page comic overview of the CARE study. The content has been designed by a Medical Illustrator experienced in creating comics, in collaboration with a multidisciplinary committee within the study team including a paediatrician, asthma and clinical research experts, and non-medical staff. Additional feedback from a Maori doctor regarding the suitability for a Maori audience, lay parents and their children (including children with asthma) have informed the design.

Parents/guardians who request for information about the CARE study at selected sites, will be randomised to receive one of two versions of the CARE study PIS (the CAREtoon PIS, or the standard PIS). This will be provided in electronic PDF or paper form, at the enquirer's preference approximately 48 hours to 2 weeks before a CARE study screening visit, at which enrolment to the sub-study and parent study will take place for eligible and interested volunteers.

Behaviour
Comparator / control treatment
A standard Participant Information Sheet for the parent CARE study (standard PIS), is the control in the sub-study.

The standard PIS follows the New Zealand Health and Disability Ethics Committee templates. It has been designed in collaboration with a multidisciplinary committee within the study team including a paediatrician, asthma and clinical research experts, and non-medical staff. Additional feedback from a Maori doctor regarding the suitability for a Maori audience, lay parents and their children (including children with asthma) has been informed the design.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will be by a secure database, which contains the randomisation sequence. A participant's PIS allocation will only be revealed to the researchers when that participant is randomised via the electronic case report form (eCRF).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed using a computer-generated sequence with varying block size between four and eight per site, and anticipated minimum centre size of 24, to maintain allocation concealment. This will be generated by the study statistician, independent of the Investigators.
Masking / blinding
Open (masking not used)

Statistical methods / analysis
Sample size is limited to the number of participants recruited from the selected participating sites, for which we aim to recruit at least 100 parent/guardian-child dyads. An achieved sample size of 50 per group has 80% power to detect a standardized mean difference of 0.56, or 90% power to detect a standardized mean difference of 0.65 (regarded as a medium-large effect by Cohen’s standards of effect sizes).

Child comprehension scores (mDICCT) will be analysed by ANCOVA with REALM-TeenS score and number of days with PIS resource prior to study visit as covariates, and randomised group as the main explanatory variable of interest.

Parent comprehension scores (mQuIC) will be analysed by ANCOVA with REALM-SF score and number of days with PIS resource prior to study visit as covariates, and randomised group as the main explanatory variable of interest.

Estimation of relative risk and associated confidence interval:
- Proportion of CARE study enquiries which progressed to CARE study screening visit after sending PIS
- Proportion of CARE study enquiries which progressed to CARE study enrolment after sending PIS
- Proportion of children who the PIS helped understand the study
- Proportion of parent/guardians and children who would have preferred to receive each version of the PIS

T-test or if normality assumptions are strongly violated, Mann-Whitney test with Hodges-Lehmann estimator of location:
- Percentage PIS read (VAS) by those who do not progress enquiry to screening visit
- Percentage of PIS read (VAS) by adults and children
- Percentage (VAS) how much did PIS help with understanding
- Percentage (VAS) how much did PIS help with explaining to child
- Percentage (VAS) how much did comic illustrations help with explaining to child

Descriptive statistics will be generated as follows: categorical data will be described by counts and proportions; count data will be described by rates and total counts in relation to observation time; ordinal data will be described by cross-tabulation and summaries as described for continuous data; and continuous data will be described by mean and standard deviation (SD), median and 25th and 75th percentiles as the inter-quartile range (IQR), and minimum (min) to maximum (max) as the range. Free-text data will be manually reviewed by the study team without formal qualitative analysis. This applies to:
- Exit survey for those who do not progress a CARE study enquiry to a screening visit
- Feedback survey for parent/guardian and child participants of the CAREtoon sub-study
