Stigma of living as an autism carer: a brief psycho-social support intervention (SOLACE). Study protocol for a randomised controlled feasibility study.

Background: Stigma is prominent in the lives of autistic individuals and their families and contributes significantly to the challenges faced by families raising an autistic child. Parents and carers can feel blamed for their child's behaviour, feel socially excluded and isolated and suffer from low self-esteem and poor psychological well-being. This increases the risk of experiencing self-stigma which further exacerbates these and other negative consequences. Therefore, there is a need for interventions that help parents/family carers cope with autism-related stigma as well as prevent the internalisation of stigma.

Objectives: The primary objective of this study is to assess the feasibility and acceptability of a stigma support intervention for parents and carers of autistic children titled 'Stigma of Living as an Autism Carer (SOLACE)'. The secondary objective is to explore the preliminary impact of the intervention on the mental health of the parents and carers.

Methods: A pilot randomised controlled trial feasibility study will be implemented. A group receiving the SOLACE stigma support intervention ( = 12) will be compared against a control group not receiving any additional intervention ( = 12). Family carers of autistic children up to the age of 10, who have been recently diagnosed or are currently undergoing diagnosis, will be recruited for the study. Participants will be randomly allocated to the intervention or control group and will take part in eight weekly group-based sessions designed to improve the well-being of the parents primarily through increasing their resilience to stigma. Feasibility will be determined by recruitment and retention rates and a qualitative focus group evaluating the acceptability of the intervention and outcome measures. The primary outcome of interest is psychological well-being, and depending on the normality of distribution, independent samples tests will be used to compare the outcome scores between the two groups and dependent samples tests for differences within the group. Other outcomes of interest are stigma, self-stigma, self-esteem, self-blame, social isolation, self-compassion and perceived responsibility and control.

Discussion: Results from the feasibility randomised controlled trial will be used to refine the study protocol and inform the design of an intervention for future use in a larger, powered trial. SOLACE could potentially improve the psychological well-being of parents/family carers of autistic children through increased resistance to stigma.
