Brief Report: Chimpanzee Social Responsiveness Scale (CSRS) Detects Individual Variation in Social Responsiveness for Captive Chimpanzees.

Faughn et al. (2015) built a new rating scale for chimpanzees. The Chimpanzee Social Responsiveness Scale looks like the human SRS we already know.

Keepers, researchers, and caretakers filled out the form for captive chimps. The team checked if different raters agreed and if scores lined up with each animal’s social rank.

The scale worked. Raters gave similar scores, so the tool is reliable.

Lower-ranking chimps earned higher CSRS scores. In other words, the animals that get pushed around look more socially atypical on the form.

Huang et al. (2014) did the same kind of job for toddlers. They adapted the CSBS-DP for Taiwanese children and found culture shifts scores. Both papers show you must re-validate a scale when you move to a new group, whether that group speaks a different language or lives in a zoo.

Baker et al. (2025) also built a new tool, the BSP-CAT, for auditing behavior plans in human services. Like Carley, they proved raters could use the sheet consistently. Together the trio says: build, test, then trust your checklist.

Slaton et al. (2017) and Fruchtman et al. (2025) went one step further. They used their assessments to pick treatments that cut problem behavior. Carley stops at description, but the jump from rating to intervention is the logical next move for anyone working with social deficits.

You probably assess social skills every week. This paper reminds you to check rater agreement before you trust the numbers. It also shows that social rank, not just diagnosis, can shape scores. When you see high SRS numbers in a client, ask: is this child low on the classroom pecking order? A simple rating scale can open that conversation and guide where you place peer buddies or teach assertiveness.
