Measuring staff perceptions of challenging behaviour: the Challenging Behaviour Attributions Scale (CHABA).

The authors built a new 30-item survey called CHABA.

It asks staff why they think challenging behavior happens.

They tested it with 133 staff from learning-disability services.

The scale worked well.

It showed clear factors like biomedical causes and learned causes.

Staff could fill it out in under 10 minutes.

Poppes et al. (2016) later used CHABA with staff who support people with profound disabilities.

They found the same scale still works, but staff gave low scores overall.

This shows CHABA can travel across settings.

Prigge et al. (2013) and Freeth et al. (2019) tested other behavior checklists.

They found age and verbal ability change scores.

CHABA avoids this problem by asking about staff beliefs, not child skills.

Lambrechts et al. (2010) watched staff respond to behavior.

They saw quick verbal reactions, not thoughtful attribution.

CHABA gives you the missing piece: what staff think before they act.

You can now measure staff beliefs in under 10 minutes.

Use CHABA during supervision to spot gaps in understanding.

When scores lean toward biomedical causes, plan extra training on learning principles.
