Temper outbursts in Prader-Willi syndrome: causes, behavioural and emotional sequence and responses by carers.

Tunnicliffe et al. (2014) · Journal of intellectual disability research : JIDR 2014
★ The Verdict

Temper outbursts in Prader-Willi follow routine changes and move from anger to remorse in minutes.

01Research in Context

01

What this study did

The team talked to 32 carers of people with Prader-Willi syndrome. They asked what happens right before, during, and after a temper outburst.

Carers were parents, siblings, or paid staff. All had lived or worked with the person for at least six months.

02

What they found

Almost every carer said the same trigger: a change in daily routine. A new bus driver, a moved chair, or a late meal could start the storm.

The outburst itself was fast. Anger peaked in minutes, then flipped to tears and sorry hugs. Knowing the arc helps carers stay calm.

03

How this fits with other research

Zyga et al. (2020) later counted stress levels in preschool families. They showed the earlier the outbursts start, the heavier the parent stress. Sawyer et al. (2014) gives the why: routines break and meltdowns follow.

Dudley et al. (2019) used ABA to stop food stealing in the same syndrome. Their single-case won, but they never tracked temper. Together the papers say: treat the food, plan for the rage.

Boxum et al. (2018) built a short parent survey called PAFAS. Their tool could turn P’s interview findings into quick numbers for clinics.

Why it matters

You can now predict and prep. Post the day’s schedule where the client sees it. Give 5-minute warnings before any switch. When the anger peaks, keep language short and space safe; remorse arrives soon after. Share the anger-remorse timeline with new staff so they don’t escalate with extra words or restraint.

03Original abstract

BACKGROUND: Temper outbursts are common in Prader-Willi syndrome but rarely described in detail. This study investigated the phenomenology of temper outbursts in terms of antecedents, sequence of behaviours and emotions and intervention strategies used. METHOD: A semi-structured interview about temper outbursts was conducted with the main carers of seven children (9.5 to 16.7 years) and seven adults (24.7 to 47.10 years) with Prader-Willi syndrome (10 male, 4 female). Reliability and validity of the interview results was established. RESULTS: Various setting events increased and reduced the likelihood of temper outbursts. The most common antecedent was a change to routine or expectation. There were marked similarities in the sequence of behaviours and emotions during temper outbursts, with anger rising quickly followed by expressions of remorse and distress at the end of an outburst. DISCUSSION: The sequence of behaviours and emotions within outbursts was similar to that described in temper tantrums in typical development. Cognitive and emotional processes are likely to be important in the understanding of temper outbursts with implications for early intervention.
