Goal Attainment Scaling Wigan EPS Approach Simon Jenner Based on work by Francis Mallon (Birmingham)
The ‘Customer’ • Crucial question not ‘Who is my customer?’ but ‘Who is my customer’s customer?’ – Emphasises that the purpose of service provision is to enable the recipient to meet their customers’ needs.
Problem: • How to evaluate IMPACT of differing approaches with one measure, eg outcomes for a 16 year old with Aspergers educated at home vs. a 4 year old with PMLD vs. whole school work on IEPs
Implication • Service evaluation should go beyond the views of the school to looking at outcomes for children – trying to get at the ‘co-production of added-value’… (Checkland & Scholes, 1993) • Requires a common approach to monitoring and evaluating pupil progress.
Common approach • ‘Among the candidates for adoption as the common approach, Goal Attainment Scaling (GAS) would appear to have much to commend it.’ (Baxter & Frederickson 2005) • ‘… GAS is an approach that could significantly assist EPs in evaluating individual outcomes and … allow collation of information across services.’ (Frederickson 2002).
Goal Attainment Scaling (GAS) • Developed by Kiresuk & Sherman (1968) as a method for evaluating mental health services. • Provides an individualised, criterion-referenced approach to describing behaviour change and documenting the outcomes of intervention programmes. • Provides a measure of the progress towards goals, defined on a 5 point scale.
Some examples of GAS applications: • Evaluating a behaviour support service (Imich & Roberts, 1990) • Gross motor function in cerebral palsy (Wright, Boschen & Jutai, 2005) • Behavioural interventions (Urwin and Ballinger, 2005) • Student self-monitoring (Weymeyer et al., 2003) • Brain injury rehabilitation (Ponsford et al., 1999) • Pain evaluation programmes (Zaza, Stolee & Prkachin, 1999) • Pupil mentoring evaluation (Balcazar et al., 2006) • In Birmingham (Mallon, 2008)
Goal Attainment Scaling - Reliability • Good inter-rater reliability of 0.9 and above have been reported using GAS
Trialled in Wigan by EPS last term • Proposal to try across a wide range of work this year • Settings may find it useful for themselves
Goal Attainment Scaling procedure • Prioritise up to 3 areas of concern. • Establish up to three goals (can be more than one per problem area). • Select a baseline descriptor for each against which progress can be measured (evidence) • Specify the expected level of outcome after intervention ( 0).
GAS Procedure cont. 5. Specify +1, +2, -1, -2 where +1 = more than expected +2 = much more than expected 0 = expected improvements -1 = less than expected -2 = much less than expected 6. Mark baseline as measure (usually in -1 or -2). 7. Repeat for each goal. 8. Decide review date.
GOAL: to raise X’s self esteem When asked about self… • -2 Identifies 0 positive things • -1 Identifies 1 –2 positive things • 0 Identifies 3 – 5 positive things • +1 Identifies 6 - 8 positive things • +2 Identifies 9+ positive things
Goal: Produce more classwork With fewer than 2 prompts… • -2 Completes 0-30% • -1 Completes 31-60% • 0 Completes 61-75% • +1 Completes 76-90% • +2 Completes 91-100%
Example 1 • Concern: H. is isolated on the playground; does not have the skills to approach others, or join in games. (diagnosis of ASD) • Baseline Descriptor H has not shown or is unable to use any of the skills that are part of interacting with peers socially on the playground. He is isolated on the playground.
Example 1 cont. +2 He will be observed as being a leader of games or as a child who starts up games. +1He will be playing with others five times a week. 0 He will be involved in playing with others on the playground 3 to 4 times a week. -1 He will be involved in playing sporadically. (average one day a week) -2 He will remain isolated on the playground.
Example 2 • Concern: Behaviour of two pupils in Reception setting • Baseline descriptor: Two pupils (one in each Reception class) have been identified as displaying behaviours which are preventing them (and others) from accessing the curriculum
Example 2 Cont. The strategies identified will… +2 eliminate the challenging behaviours displayed by the identified pupil and will have a positive impact on the behaviours of the whole class. +1 significantly reduce the frequency of the challenging behaviours displayed by the identified pupil, and will have a positive impact on the behaviours of the whole class
Example 2 cont. 0 reduce the frequency of the challenging behaviours displayed by the identified pupil -1 slightly reduce the frequency of the challenging behaviours displayed by the identified pupil -2 have no effect on the frequency of the challenging behaviours displayed by the identified pupil
Example 2 cont. - Evidence • the pupil is beginning to be able to focus on his learning as he is no longer displaying behaviours which prevent him accessing the curriculum • peers playing collaboratively with the pupil, and he is no longer socially isolated as previously • communication between the pupil and adults has improved, and the pupil is now able to express his needs effectively due to strategies used by staff to elicit his views
Example 3 Concern: Evaluation of a training course Baseline descriptor: Training not begun, preparation stage. Goal: For training to be successful.
Example 3 cont. + 2 70% comments positive and attendees report implemented strategies +1 60% comments positive and attendees report implemented strategies 0 50% comments positive attendees report implemented strategies -1 40% comments positive -2 30% comments positive
Guard against goals that are too easily accomplished, or too difficult. Realistic expectations for outcomes should be used to evaluate the programme accurately. • The outcomes should be measurable and specific. • While the outcome does not have to quantified, it must be stated so that hypothetically two independent observers could agree on whether it has been obtained
Some common problems • Use of jargon or technical language • Vagueness • Overlapping levels • Gaps between levels • Multidimensional scales • Time consuming?
Goal Attainment Scaling (GAS) • Provides an explicit framework to specify targets, progress and outcomes of intervention. • Can be used flexibly – targets can be negotiated and adjusted as required. • It encourages collaborative goal setting and pupils, teachers and parents can be involved. • Is becoming increasingly widely used in assessing the adequacy of progress and evaluation of outcomes.
