Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The SIBS-ONLINE intervention consists of four sessions delivered through a secure, password-protected video conferencing software on the Internet (e.g. Zoom, Skype, WebEx) by group leaders and two homework and feedback sessions at home. These sessions will be conducted over the course of 4-5 days in a row. Groups The homework and feedback sessions will be conducted using ‘break out rooms’ in the videoconferencing platform so that the parent-sibling dyads have privacy from the rest of the group, and so the group leader can intermittently drop-in on the conversation and provide guidance and feedback.

The first siblings-only and parents-only sessions will last for 80 minutes. The second such sessions will last 60 minutes. The joint parent-sibling sessions will last approximately 50 minutes, with the group leader joining each dyad for approximately 10 minutes each.

We will pilot SIBS-ONLINE with N=30 families (30 siblings and 30 of their parents), conducting five groups with six participants in each group.

Fully trained staff from UNSW and Canteen will conduct the group sessions. Training will consist of two full days of learning about the intervention and role playing. These training sessions will be conducted either face-to-face or via video-conferencing and led by Prof Fjermestad and Dr Vatne. CanTeen Australia are a community organisation who offer individual and group counselling to adolescents and young adults (aged 12-25) with cancer and their families. They have world-class expertise in the provision of tailored counselling services, and have worked extensively with siblings of young people with cancer (please see: https://www.canteen.org.au/young-people/my-brothersister-has-cancer/).

Parents and siblings will engage in sessions with group leaders separately from each other, while homework and feedback sessions will be conducted together. The sibling sessions will focus on discussing their emotions, thoughts, and feelings about their brother or sister’s chronic illness and writing down questions they have about those illnesses for their parents. The parent sessions focus on communication training, using video examples of real sibling-parent dialogues and open-exploratory communication as basis for discussion. Parent sessions also comprise psychoeducation about sibling challenges, and introduction to cognitive-behavioural principles about emotional coping.

Each group’s first session will involve an introduction to the intervention and the other participants in their respective groups. For siblings, the first sessions will also focus on sharing thoughts about their brother/sisters’ illness and writing any question(s) they have for their parents. For parents, the first session will overview and provide information about the intervention as well as exercises which will encourage parents to listen, explore, and validate the siblings’ thoughts about the disorder.
After each group has had their first session, a joint session will be conducted by the parents and siblings at home. The joint sessions will incorporate integrated sibling-parent dialogues in which siblings present their questions and, in turn, parents practise communication skills learned in initial session. Group leaders will intermittently join these conversations, and provide each parent with personalized feedback on their communication skills.

After the joint session, parents and siblings will reconvene in their groups for one more separate session. Siblings will focus on challenging emotions and feelings they have about their brother/sisters’ illness and writing them down to express to their parents. Parents will focus on listening, exploring, and validating emotional challenges. A second joint session will then be held where the siblings present their challenges to the parents who further practise their learned communication skills.

Each group has two group leaders. In SIBS-ONLINE, the same two group leaders will run the sibling and parent groups. Group leaders will 1) be an employee or student of either UNSW or Canteen; 2) hold at least a Bachelor’s degree in psychology or social work, with work experience with mental health; and 3) be trained by the lead investigator to run the groups. Group leaders, in addition running the SIBS-ONLINE groups, will be involved in collecting research data through the completion of templates after each group session

Adherence will be monitored by using attendance checklists. Each group leader will also complete the Competence and Adherence Scale for Cognitive Behavioural Therapy after each session. They will rate themselves for each CAS-CBT item on a 0-6 scale (“none” to “thorough” for adherence, “poor” to “excellent” for skills).

Sample size calculation

The statistical power of a comparison of paired samples depends on the within-individual correlation over time. A study in Dutch 10-to-14 year-olds estimated a correlation coefficient of 0.87 (95% 0.80–0.91) [Muris et al, 2003)] in the self-reported SDQ total difficulties score over an interval of 2 months. The lower bound of this confidence interval may be considered as a conservative estimate of the correlation that we would expect to see over the much shorter duration of SIBS-ONLINE.
We will pilot SIBS-ONLINE with N=30 families (30 siblings and 30 of their parents), conducting five groups with six participants in each group. Given that the changes within each group will not be independent, the power also depends on the intra-group correlation.

If the within-individual correlation is at least 0.80 and the within-group correlation is no larger than 0.35 (as evidenced in the evaluation of the original Norwegian SIBS intervention for siblings of children with chronic illness [Haukeland et al, 2020]), then a sample size of 30 siblings provides greater than 80% power to detect a large change (0.8 standard deviations) in SDQ total difficulties score, using a two-sided test with a significance level of 0.05.

There is a possibility that multiple siblings, or multiple parents from a family of a child with a chronic illness will want to participate. If this case arises, any data from those participants will be potentially correlated, reducing the effective sample size. For each family that contributes multiple siblings or parents, the target sample size will be increased to ensure that there are at least 30 independent individuals.


Analysis plan

SIBS-ONLINE has a single-arm pre-post design with the primary outcome being the difference in SDQ scores from pre-intervention to immediately post-intervention, reported by siblings and parents. The primary analysis will be a test of the null hypothesis that the mean difference between the paired scores is equal to zero, accounting for within-group correlation by using a repeated-measures regression model with cluster-robust standard errors. The estimated difference will be presented with a two-sided 95% confidence interval.

Analyses of secondary outcomes will be performed in a similar manner, as appropriate for the specific outcome.

In the case where multiple siblings or parents from the same family are included in the study, statistical tests that account for this additional non-independence will be used.

Analyses will be conducted in SPSS.

Summary
Brief summary
This study aims to pilot an intervention (SIBS-ONLINE) for siblings of children with chronic illness to ensure it: 1) addresses the ongoing realities of siblings’ potential caregiving responsibilities; 2) addresses issues unique to being a sibling of a child with chronic illness; 3) allows siblings to meet and interact with other siblings; 4) improves family communication and family functioning. The original intervention (called SIBS) was developed by Prof Fjermestad and Dr Vatne and their team in Norway. We are working with consumer representatives from Canteen Australia to modify the intervention for an Australian audience. Part of the modification has been to deliver the intervention via video-conferencing. This new, updated version of the intervention for Australian families is called SIBS-ONLINE.

Who is it for?
Eligible participants will be adolescents aged at least 12 years and at most 18 years of age, who live with at least one brother or sister with a chronic illness who has been diagnosed greater than or equal to 6 months prior to the study. One of the siblings’ parents will also be eligible to participate. Participants must be able to give informed consent and speak/read conversational English. All participants will be required to have access to the internet and a computer/smartphone/tablet with web-cam and microphone.

Details of the study
The SIBS-ONLINE intervention consists of four sessions delivered via video-conferencing (e.g. Skype) by group leaders (two with only parents and two with only siblings) and two homework and feedback sessions at home. The sibling sessions will focus on discussing emotions, thoughts, and feelings about their siblings’ chronic illnesses and questions they might ask of parents. The parent sessions focus on learning about challenges common to siblings and encouraging open-exploratory communication with their children. The homework and feedback sessions will be conducted with siblings and their parents together. Clinical staff and psychosocial researchers from BSU and Canteen will be trained and act as group leaders for the parent and sibling groups.
