Social Capital and the Reciprocal Nature of Family Relationships: The Perspective of Individuals With Mild Intellectual Disability.

Giesbers et al. (2020) asked adults with mild intellectual disability to list every family member who gives support.

They then asked, "Do you also help that person back?"

The survey counted how many ties were two-way.

Only 30 % of family support ties were reciprocal.

Parents gave the most help, yet rarely received help in return.

Siblings and partners were named less often, but when they were, the give-and-take was closer to even.

Robertson et al. (2013) mapped the same group earlier and showed large, contact-rich networks.

Their work looked at size and frequency; H et al. added the reciprocity lens and revealed the flow is mostly one-way.

Dudley et al. (2019) found siblings actually make most formal decisions for adults with IDD.

This seems to clash with H et al., who show siblings are seldom listed as supports.

The gap is methodological: M et al. asked who decides, while H et al. asked who helps day-to-day.

Byra et al. (2025) later showed sibling relationship quality predicts life satisfaction, backing H et al.’s call to grow two-way sibling ties.

Parents won’t be around forever.

If only one in three family ties is mutual, your client risks isolation later.

Use role-play, shared chores, or joint budgeting tasks to teach reciprocal skills with siblings or partners now.

Track who gives and gets help each week; shift sessions toward balanced exchanges.
