Ongoing use of an affective rating scale in the treatment of a mentally retarded individual with a rapid-cycling bipolar affective disorder.

Staff tracked one adult with intellectual disability and bipolar disorder. They used a short mood scale twice a day for many months. The team wanted to see if simple ratings could show mood swings.

No fancy machines. Just staff circling numbers after each shift.

The scale caught clear up-and-down cycles. Staff could see when the client was heading into mania or depression. The pattern matched clinical notes.

The ratings helped decide when to change meds or add support.

Willemsen-Swinkels et al. (1998) later showed support workers can spot full psychiatric disorders with the Mini PAS-ADD. They got 81% agreement with doctors. Attwood et al. (1988) proved the idea works for daily mood, not just big diagnoses.

Romani et al. (2018) took data quality further. They gave staff clickers and timers on a child unit. IOA jumped for all eight kids. The 1988 paper did not check IOA, so Romani shows how to make staff ratings more trustworthy today.

Matson et al. (2004) and Schaaf et al. (2015) moved the same idea to kids and ADHD. Teachers used the ABC-C and SAID scales. All studies agree: brief informant ratings work across ages and symptoms.

You can start tomorrow. Pick two times a day when your client is visible. Rate mood, energy, or irritability on a 1-5 line. After two weeks look for highs and lows. Share the chart with the psychiatrist. The simple act often reveals patterns everyone else missed.
