Applied Behaviour Analysis: Contributions to Best-Practice Residential Services Oliver Mudford, I-Chen Sharon Ho, Kylie Jeffrey, Sheree Adams, & Katrina Phillips University of Auckland ABA Programme Staff and Graduates National Residential Intellectual Disability Conference: Auckland. February 14th 2008
Outline What is Applied Behaviour Analysis? ID residential services, social policy and ABA: Brief history ABA approach to skill teaching Examples of increasing skills ABA approach to problems in 21st Century Examples of decreasing problems Encouraging evidence-based practices in ID services
What is ABA? A science that . . . applies procedures derived from the principles of behaviour . . . (especially, reinforcement) systematically . . . (not randomly) to improve socially significant behaviour . . . (important for person) to a meaningful degree . . . (that is, improves lifestyle) and to show that the procedures used were responsible for the improvement. (. . . that is, provides evidence)
What happened to ABA in 1990s? • ID services de-professionalised • “Teaching people skills for living will occur naturally by contact with community” (. . . not true for many) • “Problem behaviours would not occur with good values and community living” (. . . not supported by evidence) • Training courses to provide skills to staff ended • Psychologists (some were ABA) “not needed” • ABA psychologists moved to other populations • Clinical Psychology lost interest in ID (and ABA) • ABA teaching in NZ universities declined - No new ABA specialists trained
Meanwhile, ABA advances from late-1980s to present • Research on individualising reinforcers for increasing behaviours and teaching new skills: preference and reinforcer assessment • More research on individualising interventions for problem behaviours almost eliminating need for 1970s treatments that fail services’ “values check”: e.gs., functional analysis, NCR, FCT • ABA practitioner credentials established internationally: Behavior Analyst Certification Board (BACB) from 2000 • University courses specialising in ABA re-established - from 2003 in NZ

Conclusion • Task analysis successful with other goals • Success verified with client, family and staff • 26 sessions over 1 ½ months to teach a skill that leads to a lifetime of independent activity
Increasing Independent Engagement with Household Chores I-Chen Sharon Ho, MSc, PGDipAppPsych ABA Graduate 2007 Now at IDEA and Blomfield School, Whangarei
Background • Client: Wyatt • Goal: To increase client’sindependence when engaging in chores. • Goal rationale
Programme • Behavioural Momentum • What is it? • Can we make the strategy more efficient?

Increasing Meaningful Engagement in Adults with Intellectual Disabilities Sheree Adams, MA, PGDipAppPsych ABA Graduate 2007 Now at Centre for Autism & Related Disorders
Introduction • I compared two methods to increase engagement levels of four men with developmental disabilities who live in staffed residential care. • “Engagement” in worthwhile leisure and domestic activities
Method • Participants were four men aged 25-35 and six staff aged 28-55 • The study consisted of four phases, baseline, alternating treatments, single treatment and follow-up. • Both resident (levels of engagement) and staff behaviour (interactions with residents) were recorded during all observations • The interventions were administered in an alternating fashion, on the same day. One in the morning and in the afternoon .
Two Interventions • In Treatment A the staff were told “there is not enough activity going on, would you do something to increase it please?” • In Treatment B staff were told the above and given a written list of over 50 suggested activities and asked to approach clients and offer a choice of activity. The list was removed at the end of the observation. • Staff were thanked regardless of the level of subsequent activity
Phase II Baseline Phase I F/U Intervention B DO Staff DT DM Prompting + Reinforcement PN sessions PERCENTAGE OF INTERVAL Intervention A Level of engagement Figure 1: Percentage of session spent engaged for all individuals. Lines represent level of engagement across all conditions. Bars represent the percentage of intervals staff spent attempting to engage individuals and prompting them to maintain engagement, for all staff, across baseline, treatment and follow up phases. F/U is follow-up. 26
Conclusion • Baseline levels of client engagement were very low across all individuals • Intervention B (provision of a list) was more effective, therefore it is necessary to give staff a written list of suggested activities and to offer the individuals a choice of activities to obtain a stable increase in engagement levels • Prompting and reinforcement was necessary to increase engagement levels with one individual (PN)
Goals for residents guided by: • Discussion, prioritising, and agreement with resident, staff, and family • Active participation – busy • high activity = highly reinforcing living environment • Teach and maintain functional skills • Increasing signs of happiness cont . . . .
Guiding principles for goals (cont) • Minimise disruptive behaviours • Replace with functional skills • Minimise restrictions • Encourage and teach choice • Create and maintain a stable environment • not chaotic, for residents and staff • Maximise safety • from own or others’ behaviour ABA in practice is not really a values-free activity – is it?
ABA approaches to reducing problems Examples of decreasing behaviours Note that these rely on changes in reinforcement – not punishment Teaching and training conducted for clients and staff of residential services in Auckland
Comparison of Interventions to Decrease Grabbing by a Man with Intellectual Disabilities Katrina Phillips, MSc, PGDipAppPsych, BCBA ABA Graduate 2007 Now at Rescare Homes Trust and UoA
Function of behaviour Social Positive Reinforcement Decreasing problem behaviour over two time periods using NCR (non-contingent reinforcement) Activity engagement Extinction (i.e., ceasing to reinforce) Combinations of the above Programme
Figure 1. Frequency of BN’s grabbing during the morning shift (90 mins). Graph shows four different interventions: baseline (no intervention), task engagement and extinction, task engagement, extinction and NCR, or extinction and NCR.
Conclusion Grabbing of other residents reduced to zero with a combination of providing engaging activities for BN, non-contingent attention systematically every 5 minutes, and attending minimally to instances of grabbing
Communication Training and Decreasing Food Stealing I-Chen Sharon Ho, MSc, PGDipAppPsych ABA Graduate 2007
Background • Client: Alf • Goal: To increase Alf’s ability to request for food using a picture card • Goal rationale and function of challenging behaviour (food stealing)
Programme • Picture Exchange Communication • Extinction, i.e., stopping food stealing • Block Alf’s reach for others’ food • Teach others to move their food out of Alf’s reach
Figure 1. Percentage of independent correct responses across sessions as a function of picture exchange communication systems training.
Figure 2. Frequency of stealing attempts across sessions as a function of extinction.
Before behavioural reinforcement procedures were widely used with individuals with severe or profound intellectual disabilities, those individuals were frequently medically sedated and warehoused – living zombies . . . But once systematic reinforcement programmes began to be used, these individuals could be taught many important skills, independent eating, dressing, and hygiene behaviours and vocational and recreational behaviour of which they were previously thought to be incapable. Consequently their freedom increased – now they could dress themselves, and decide what to wear; now they could feed themselves and decide what to eat. Systematic reinforcement procedures . . . increased their freedom. Stephen Flora (2007) in Taking America Off Drugs
How do staff become trained to use systematic procedures in 2008 in NZ? • Well, perhaps they don’t • Why not? The design of modern individually tailored systematic reinforcement procedures iscomplex • Too sophisticated to be learned in a 1, 2, or 3 day workshop which produce superficial (or mis-) understanding • Application of the individualised procedures is not so complex, and staff can be trained to do them • ID services need to employ qualified individuals to train others to implement behaviour change procedures effectively
ABA provides evidence-based practices [EBP] for services for people with ID ID sub-groups, e.g., MoH/MoEd ASD EBP guidelines 100s of research articles showing benefits Applications of ABA for ID overall: 1000s of research articles This evidence is not well-known to ID services maybe too complex to interpret or perhaps known, but ignored or denigrated by those recommending alternatives that have no sound evidence base
Encouraging evidence-based practices [EBP] in ID services • Recognise that ABA has changed since the 1980s “behaviour mod” days • ID services should consider committing to using EBPs, such as ABA • Encourage, nurture & support training to develop NZ expertise with EBPs • Recruit ABA expertise to educate management (and MoH, NASCs, etc.) and to train residents and staff • Reward staff who use EBPs effectively • NRID? – lobby MoH on these issues • Like Queensland Government have adopted EBP for ID
