Samenvatting

Aim Direct Support Professionals (DSPs) provide important lifestyle behaviour support for people with intellectual disabilities (ID). They can use behaviour change techniques (BCTs) to do this. We aimed to evaluate which BCTs are used for supporting healthy lifestyle behaviour of people with moderate to profound ID by DSPs. Method 18 DSPs were observed in their daily work with audio-visual recordings. The Coventry Aberdeen London Refined (CALO-RE-NL) taxonomy was used for coding BCTs. Differences in the characteristics of people with ID and DSPs in relation to the used BCTs were evaluated. Results Most of the coded BCTs were used by DSPs (33 BCTs out of 42), but they rely heavily on nine of them. DSPs used ‘feedback on performance’, ‘instructions on how to perform the behaviour’, and ‘doing together’ mostly. No statistical differences were found for the characteristics of people with ID or DSPs for the top nine used BCTs. Conclusion DSPs mostly rely on nine BCTs. Although no statistical differences were found, DSPs use more BCTs for people with more severe ID. DSPs who support people with severe or profound ID are more aware of demonstrating, setting graded tasks and encouraging people with ID to practice healthy lifestyle.
