Children with developmental co-ordination disorder (DCD): Is screening assessment effective? Elizabeth Stephenson, Clinical Specialist Occupational Therapist, Royal Aberdeen Children’s Hospital Rosemary Chesson Professor of Health Services Research The Robert Gordon University
Structure of presentation • DCD - Terminology • Background • Aims of project • DCD clinic and assessment procedure • Method • Results • Implications and issues
Terminology and definition • More than 20 terms exist • Definition is inconsistent • Heterogeneity of DCD group • Problems for research
Developmental co-ordination disorder (DCD) • Performance in daily activities requiring motor co- • ordination substantially below that expected for age • and cognitive ability. • Motor difficulty affects academic learning and • activities of daily living. • Not due to a medical condition such as CP, nor • meeting the criteria for PDD • Where cognitive delay exists, motor difficulty must be • in excess of it
The study • Investigation of assessment efficacy part of a wider • study • Study included survey of parent and referrer • satisfaction • Extension of study examines outcome for children • with DCD
Collaborative working • collaboration both between departments and staff in • Royal Aberdeen Children’s Hospital & the Robert • Gordon University (RGU) • long term collaboration - grown over the years. • joint working with OT department and Health • Services Research Group, RGU.
Features of collaborative working • Different perspectives • - health services researcher (non clinician) and • clinician • - child specific focus vs broad age spectrum • - different organisational contexts • Common objectives • - commitment to improve patient care • - help establish evidence-based practice • Outcomes • - publications • - future research
Aspects of research • Research includes clinical and non-clinical elements: • Clinical • assessment • screening • One stop clinics • Non-clinical • parental views
Research to date regarding children with DCD High volumeLow volume - Assessment (incl tools) - Screening - Cause - One stop clinics - Treatment - Outcomes
Outcome Studies • Few longitudional studies. • Main emphasis on motor & academic outcome. • Some work on associated emotional/behavioural • problems. • Effects on family neglected • - none longitudinal • - very few studies • earliest and largest • (Chesson, McKay & Stephenson 1990) 31 children
Aims of the project Evaluation of the accuracy and efficacy of the occupational therapy screening within a one stop clinic procedure for children with DCD
Establishing the DCD clinic • Increasing demand on occupational therapy service • ‘One stop’ clinic implemented trial • Medical and occupational therapy screening on same • day • After 3 years (1995-1997) evaluation required
Basic screening procedure • History • Clinical observance • Drawing and writing • Posture imitation
Further assessment • Additional screening tests: motor performance • items; visual-motor skill and visual perception • Fuller assessment: Movement ABC; VMI; • MVPT/TVPS (sensory profile)
Method • Two independent assessors recruited • Records of 36 children scrutinised (15% of three • year study group) • Data entered into SPSS-PC • Kappa values calculated to establish degrees of • concordance in 5 areas.
Areas examined • Accuracy of Clinical Observations • Further tests following screening • Diagnosis - sub-typing • Intervention required • Resource need: clinical/educational
Results • Overall high levels of concordance between clinician screening & two external assessors • Extent of concordance established using Kappa • poor <or = 0.21 • fair 0.21 - 0.40 • Moderate 0.41 - 0.60 • Sustantial 0.61 - 0.80 • Good >0.80
Concordance Highest levels: Clinical observations (at least 0.80) Lowest levels: Intervention required (0.08)
Concordance cont. • Clinical observations • Highest levels of concordance between: • Clinician & Assessor 1 • on neck • reflexes • Clinician & Assessor 2
Additional Tests Tests indicated to supplement basic screening (selection from list) None considered ‘good’ & none ‘poor’ Highest agreement between C & Assessor 1 regarding visual motor test
Types of dysfunction & diagnosis • Types of dysfunction • considerable range in degrees of concordance • Primary diagnosis • 20/36 cases of complete agreement on dx • 11 cases of 2 way agreement • 5 cases where there was no agreement
Intervention Intervention C/A1 C/A2 Therapy 0.11 0.49 Therapy ideas 0.08 0.45 Referral to an. agency 0.05 0.60 reflected also in resource needed (educational or clinical)
Implications • For clinical practice • For future research
