Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study aims to explore the effects of Active Support staff training strategies on engagement and challenging behaviour (aggressive, self-injurious, destructive or significantly disruptive behaviours) in adults with Intellectual or Developmental Disabilities (IDD) and high support needs.

Key Active Support strategies that are theoretically aligned with reducing the likelihood of challenging behaviours will be taught to support staff in residential living settings. These will include:
1) Planning activities
2) Provision of choice
3) Providing appropriate levels of support to the adult with IDD to engage in a chosen activity
4) Providing positive social attention during engagement

Training will be delivered face-to-face by the researcher in line with following features of a Behaviour Skills Training protocol:
a) Short PowerPoints
b) Written information
c) Verbal explanations
d) Demonstrations
e) Roleplay
f) Feedback

There will be approximately seven, 40-minute, one-on-one training sessions per staff member. They will be scheduled for convenience over approximately 2-3 weeks. The training phase will continue until the staff member has completed 7 training sessions, and staff are able to use all the strategies with 100% fidelity. Fidelity will be checked in a role play context in sessions 4 and 5. Targeted booster sessions will be used if needed.

The fidelity of training delivery will also be monitored by an additional researcher for at least 30% of training sessions.

The intervention observation phase will occur immediately after staff have completed the 2-3 week training phase. Timing will vary in terms of participants beginning the intervention phase due to the staggered delivery of concurrent multiple baseline design. It is expected that participants will begin the intervention phase between 1-6 weeks after beginning the baseline phase.

Outcomes
Primary outcome [1] 334675 0
Challenging Behaviour, measured through direct assessment and the Challenging Behaviour Interview (CBI; Oliver et al., 2003)
Timepoint [1] 334675 0
Direct assessment of challenging behaviour will occur during every baseline observation (5-30 data points) and every intervention observation phase (5-30 data points).

Baseline observation sessions will begin for all participants after pre-assessments and trial-based functional analyses have been conducted (approximately 2-4 weeks after study commences).


The CBI will be administered as a pre and post-intervention assessment. Pre-intervention assessment will occur upon the commencement of the study, prior to trial based-functional analyses and baseline observations. Post-intervention assessment will occur approximately 2-weeks after the intervention has begun.

Timepoint [5] 423552 0
These will be measured through probes in baseline (5-20 data points) and intervention phases (5-20 data points).

Baseline observation sessions will begin for all participants after pre-assessments and trial-based functional analyses have been conducted (approximately 2-4 weeks after study commences).

Pre-intervention assessment will occur upon the commencement of the study, prior to trial-based-functional analyses and baseline observations. Post-intervention assessment will occur approximately 2-weeks after intervention observations have begun

Eligibility
Key inclusion criteria
Dyads consisting of one resident participant and one respective staff member

Resident participants:

(a) adults 18 years or older
(b) have a diagnosis of IDD and high levels of support need to be identified through the Supports Intensity Scale- Adult (SIS-A; Thompson et al., 2015)
(c) living in a residential care setting
(d) engaging in challenging behaviour that is negatively impacting the quality of life of the individual according to the Challenging Behaviour Interview (CBI; Oliver et al., 2003)
(e) not be currently receiving a formal behavioural intervention in addition to the organisations behaviour management plan.

Staff participants:
(a) regularly working with a resident that meets the above criteria
(b) expecting to continue working with this resident at least for the duration of the study.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
If the resident is actively receiving a formal behavioural intervention at the time of recruitment, they will be excluded from the study as a) intervention strategies may have the potential for conflict, b) changes in residents’ behaviour will not be clearly attributable to the current study or the formal behaviour intervention, posing challenges for both parties. However, given long waitlists for behaviour intervention services in New Zealand, participants may be on the waitlist for services and will not be discouraged from seeking these services participation.

Staff members will be excluded if they are expecting to leave their role working with the resident during the study's duration. This will maximise the likelihood of the intervention having full effect.
