Which background information is particularly valuable for planning interventions with clients who have developmental disabilities?

• A. Shoe size
• B. Family history
• C. Favorite food
• D. Hair color

Answer: (B)

Knowing a client’s family history is essential because it reveals genetic factors, potential medical risks, and the level of support available at home, all of which directly shape how an intervention is planned and implemented. This background helps clinicians anticipate possible developmental trajectories, identify conditions that may co-occur, and coordinate proactive screenings and referrals. It also informs collaboration with family members and caregivers, ensuring strategies fit the person's context and support system. By contrast, factors like shoe size, favorite food, or hair color don’t provide meaningful information for tailoring interventions or predicting needs in developmental disabilities.
