Coping of siblings of children with developmental disabilities in the Bedouin community.

Manor-Binyamini et al. (2012) asked Bedouin teens who have a brother or sister with a developmental disability how they feel about themselves and their lives. They compared these brothers and sisters to Bedouin teens whose siblings have no disability. The team used surveys and interviews to measure self-esteem, stress, and personal growth.

The siblings of kids with developmental delays said they felt just as good about themselves as other teens. Yet they also said they felt more daily stress. At the same time, they reported more personal growth—things like feeling stronger, kinder, and more mature. Higher stress and higher growth showed up together.

Findler et al. (2009) found the same boost in growth among siblings of kids with intellectual disability, but that study looked at a general population. Manor-Binyamini et al. (2012) now show the pattern holds inside the close-knit Bedouin culture. The finding also lines up with Manor-Binyamini (2014), who saw strong gratitude and social support among Bedouin mothers of teens with disabilities—suggesting the whole family can tap cultural strengths.

Poppes et al. (2016) seem to disagree at first glance. They report higher anxiety and depression in adult siblings of people with autism or unknown developmental disabilities. The key difference is age and diagnosis: P et al. studied adults, while Iris et al. studied teens. Stress may turn into mood problems later if left unchecked, so the papers together warn us to watch siblings across the lifespan.

You can stop reassuring families that “everything is fine.” Instead, validate the stress siblings feel and treat it as a signal that growth is happening. Offer these teens a short break—maybe a peer support group or a night off from chores. Small supports now may prevent the anxiety seen in adult studies later.
