Sibling Caregivers of People With Intellectual and Developmental Disabilities: Sociodemographic Characteristics and Material Hardship Prevalence.

Sonik et al. (2016) · Intellectual and developmental disabilities 2016
★ The Verdict

Sibling caregivers of adults with IDD are likely broke—screen for money stress and link to benefits.

01Research in Context

01

What this study did

van Timmeren et al. (2016) mailed a national survey to brothers and sisters who help an adult with intellectual or developmental disabilities.

They asked how often the family runs out of money for food, rent, or utilities.

The team also counted who gets food stamps, SSI, or other public aid.

02

What they found

Most sibling caregivers said they face moderate money problems.

Public benefits did not erase the hardship, but they seemed to stop the worst shortages.

03

How this fits with other research

Jones et al. (2010) looked at the same national sibling group and saw only small drops in warmth or phone calls.

The new money data extend that picture: the bond is still close, yet the wallet is thin.

Byra et al. (2025) later showed that good sibling ties protect life satisfaction.

Taken together, love and cash both need attention: warm feelings coexist with cold financial facts.

Dudley et al. (2019) found siblings often make formal decisions for the person with IDD.

When you add van Timmeren et al. (2016), it is clear that siblings give both big choices and big bucks—yet they are short on both support and cash.

04

Why it matters

During intake, ask the sibling who shows up, “How tight is money this month?”

One quick question can open the door to food stamps, utility grants, or SSI that the family never knew they could get.

Add one line to your intake form: “Do you ever run short on food, rent, or utilities?” If yes, hand the sibling a county benefits card before the session ends.

03Original abstract

In growing numbers, people with intellectual and developmental disabilities are outliving their parents, or at least their parents' ability to care for them. Consequently, adult siblings without intellectual and developmental disabilities are increasingly taking on primary caregiving responsibilities. However, adult siblings have received little study generally, and sibling caregivers have received even less. We used nationally representative data from the Survey of Income and Program Participation (SIPP) to describe the social characteristics and material hardship levels of sibling caregivers, in comparison to the general working age adult population. This study finds moderate material hardship to be pervasive among sibling caregivers, though extreme levels of hardship are possibly being abated somewhat through public benefit programs. Implications for greater service needs are discussed.
