Introduction: Sibling relationships have lifelong significance and childhood chronic illness and disability can have considerable impacts on healthy siblings, influencing development into adulthood. Research has not yet assessed well-being in this population using measures of both mental health and mental illness. Thus, this study assessed well-being in a comprehensive manner using the complete mental health (CMH) model.
Method: Participants (N = 144) included both adult siblings of those with chronic illness or disability and adults with healthy siblings. Measures of positive social, psychological and emotional well-being were used to assess mental health and a measure of depression, anxiety, and stress was used to assess mental illness.
Results: A high proportion of participants, both with and without siblings with a chronic illness or disability, were experiencing symptoms of mental illness, accompanied by high wellbeing. This indicates that many participants fit into the struggling category of the CMH model.
Discussion: The present research highlights the need for early intervention services to ensure that siblings of those with a chronic illness or disability are well supported in developing strengths, as well as managing difficulties. Results also indicate that targeting students in mental health promotion is important to encourage participation in services. Implications for rehabilitation Siblings of those with a chronic illness or disability need to be included in assessments in order to understand the experience of the family unit. It is important for families and clinicians to be aware of the needs of healthy siblings and encourage them to interact with support services in order to maximise and maintain well-being. Skills-based support could be beneficial, particularly for providing caregivers with strategies to meet the needs of both their child with a chronic illness or disability and their healthy children.
