Finding Gold in Hard Places: Young Siblings of People with Cerebral Palsy Report Unexpected Growth

For decades, research on the brothers and sisters of people with disabilities told a story of burden: elevated stress, disrupted family roles, and the quiet weight of responsibility placed on children who grew up alongside a sibling with complex needs. A new study published in Current Psychology flips that narrative on its head. The research, conducted by Raaya Alon of Michlalah Jerusalem College, examined whether emerging adults with a sibling with cerebral palsy report benefit-finding, the psychological process of perceiving positive meaning and personal growth in the midst of difficulty. The answer is a qualified and instructive yes, and the predictors of that growth turn out to be surprising in more ways than one.

Cerebral palsy is the most common motor disability of childhood, arising from early brain injury or abnormal development that affects movement, posture, and often cognition. Because its severity spans an enormous range, from largely independent ambulation to profound multiple impairments, the family experience of cerebral palsy varies dramatically from household to household. Siblings occupy a distinctive position within that experience. They are neither parents nor clinicians, yet they frequently assist with care, mediate social interactions, and share an intimate, lifelong vantage point on disability that few others ever occupy. Understanding what shapes their outlook matters not only for their own mental health but for the future caregiving and advocacy roles many will assume in adulthood.

The study recruited 99 Israeli siblings of individuals with cerebral palsy, 34 men and 65 women, all aged 18 to 27, a window developmental scientists call emerging adulthood. This life stage, roughly spanning ages 18 to 30, is a period of identity consolidation, shifting family obligations, and increasing autonomy from parents. For typically developing siblings, it is also the stage at which questions about long-term responsibility for a brother or sister with a disability begin to surface with real urgency. Participants completed four self-report questionnaires assessing their own characteristics, their perceptions of their sibling with cerebral palsy, their empathy, and their acceptance, alongside a measure of benefit-finding from the disability.

The theoretical scaffolding of the study is as important as its results. Alon grounded the work in family systems theory, which holds that each member of a family influences and is influenced by every other member, so that a child’s disability reshapes the entire relational ecology rather than a single dyad. The framework also draws on Alfred Adler’s individual psychology, with its emphasis on the formative power of early relational roles, and most specifically on the Sibling Embedded Systems Framework developed by Kovshoff and colleagues, which situates the typically developing sibling inside nested layers of influence, from the sibling relationship itself to parental functioning, family resources, and broader cultural context. Within this architecture, the study asked which variables, characteristics of the sibling with cerebral palsy, or psychosocial qualities of the typically developing sibling, would best predict benefit-finding.

The statistical story that emerged is subtle and, in places, counterintuitive. In the initial model, the sex of the typically developing sibling emerged as a significant predictor of benefit-finding, echoing a broad literature suggesting that sisters often engage more deeply with caregiving and relational meaning-making than brothers do. Yet when empathy and acceptance were added to the model, the sex effect dissolved entirely. This is the study’s most elegant finding: gender differences in positive sibling outcomes may not be intrinsic to being male or female at all, but rather a downstream product of the higher empathy and acceptance that some siblings, often sisters, bring to the relationship. In other words, the psychological variables, not biology, carry the explanatory weight.

The findings concerning the sibling with cerebral palsy cut against intuitive expectations in two directions. First, lower levels of independent functioning in the sibling with cerebral palsy were associated with greater benefit-finding in the typically developing brother or sister. One might assume that a more dependent sibling would amplify stress and crowd out positive appraisal, but the data suggest the opposite pattern for perceived benefit. Second, and in apparent tension with the first result, higher cognitive functioning of the sibling with cerebral palsy predicted greater benefit-finding. The two characteristics, physical independence and cognitive ability, thus pulled in opposite directions, implying that different dimensions of disability shape sibling meaning-making through different mechanisms rather than through a single gradient of severity.

How should these seemingly paradoxical results be read? One plausible interpretation is that greater care demands can create richer opportunities for shared experience, competence, and family cohesion, processes that benefit-finding research has documented in young caregivers broadly. Meanwhile, higher cognitive functioning may enable richer communication, reciprocal play, and a more elaborated personal relationship between siblings, which in turn feeds a sense of meaning. The study does not adjudicate between these interpretations, and its cross-sectional design cannot establish causal direction; it remains possible, for instance, that siblings who already perceive benefit report greater empathy and acceptance rather than the reverse. What the data do establish is an association pattern that deficit-oriented models of sibling experience simply did not predict.

The methodological choices deserve attention as well. Empathy was treated as a measurable psychosocial resource, consistent with classic conceptualizations of emotional empathy as the capacity to experience another’s feelings as one’s own, while acceptance captured the sibling’s affirmative orientation toward the brother or sister with cerebral palsy as a valued family member. These are precisely the malleable variables that practitioners can target. If sex differences in outcomes evaporate once empathy and acceptance are accounted for, then interventions that cultivate empathic understanding and acceptance, rather than interventions tailored crudely to gender, may be the more promising route to supporting siblings. That is a genuinely actionable translation of a statistical interaction pattern, and it aligns with a broader movement in developmental disability research away from cataloguing risk and toward identifying strengths.

That movement, often described as a shift from deficit-based to strength-based models, has gained momentum across the sibling literature in recent years. Studies of siblings of people with autism, Down syndrome, and intellectual disability have repeatedly documented elevated prosocial competencies, resilience, and in some cases posttraumatic growth, the positive psychological change that can follow struggle, a concept formalized by Tedeschi and Calhoun. Benefit-finding occupies a central place in this literature because it appears to act as a protective factor, buffering distress in caregivers and young carers alike. The present study extends this evidence to a population, adult siblings of people with cerebral palsy, that has received comparatively less positive-psychology attention than sibling groups in autism research, despite the distinct demands that a primarily motor disability imposes on family life.

The study’s limitations frame the proper scope of its conclusions. The sample was Israeli, modest in size, and disproportionately female, and all measures were self-reported; the data are also not publicly available for reasons of ethics and privacy. Emerging adults who volunteer for sibling research may differ systematically from those who do not. Nevertheless, the core message stands on solid conceptual ground: the psychosocial qualities a sibling brings to the relationship, especially empathy and acceptance, are more powerful predictors of positive meaning-making than demographic category or any simple measure of disability severity. For clinicians designing sibling support programs, for parents wondering how best to nurture both children in a family touched by cerebral palsy, and for researchers building the next generation of strength-based models, the finding offers a clear and quietly optimistic directive: the path to growth runs through connection, understanding, and acceptance, not around them.
