Insights
This study found that direct carer reports are effective for assessing childhood disability, offering comparable results to medical records. Revisions to the 1985 Office of Population Census and Surveys (OPCS) disability criteria are suggested for future use.
Area of Science:
- Pediatric Health
- Disability Studies
- Public Health Research
Background:
- The 1985 Office of Population Census and Surveys (OPCS) disability survey methods were established for adult populations.
- Applying these methods to children requires adaptation and validation against other data sources.
Purpose of the Study:
- To adapt and reapply 1985 OPCS disability survey methods to a pediatric sample.
- To compare disability prevalence derived from OPCS criteria with carer reports and medical records.
- To evaluate the suitability of modified OPCS criteria for assessing childhood disability.
Main Methods:
- An analytical study conducted in a UK Community Child Health Department.
- Inclusion of principal carers of 100 children (aged 5-15) from a district special needs register.
- Comparison of disability data from three sources: modified OPCS criteria, carer interviews, and existing medical records.
Main Results:
- Medical records contained diagnoses in 46% of cases, with carers generally aware.
- Modified OPCS criteria showed similar prevalence to medical and carer data for certain functions (Hand, Personal care, Consciousness, Continence).
- Higher prevalence was noted for Locomotion, Communication, and Hearing using OPCS criteria; Vision data showed significant disagreement due to differing definitions.
- Substituted criteria (Standard Attainment Targets for learning, General Health and Behaviour Questionnaire for behavior) provided comparable prevalence figures to carers and medical records, with GHBQ indicating increased problems.
Conclusions:
- Diagnostic labels have limited utility in assessing disability in children.
- The validity of some 1985 OPCS threshold criteria is questionable, necessitating reassessment.
- Direct carer reports are a practical and effective method for collecting population disability data, with caution for vision assessment.
- Further research is recommended for Standard Attainment Targets and the General Health and Behaviour Questionnaire in disability benchmarking.
Objectives:
To reapply 1985 Office of Population Census and Surveys (OPCS) disability survey methods, modified as necessary, to a sample of children to ascertain presence of disability. To compare OPCS-based prevalence with prevalence based on carer's views and medical records.
Design:
Analytical study. Setting Community Child Health Department in UK.
Participants:
Principal carers of 100 children aged 5-15, selected from a district special needs register. Main outcome measures Comparable information about disability from three sources and diagnosis from carers and medical records.
Results:
Medical records of 46% contained a diagnosis. Carers were always aware of this, although a single question did not always elicit their knowledge. OPCS-derived threshold disability criteria in categories of Hand function, Personal care, Consciousness and Continence gave prevalence results similar to medical records and carers. OPCS criteria yielded higher prevalence of disability in the areas of Locomotion (8%), Communication (14%) and Hearing (18%). Carers, OPCS and medical records disagreed markedly about prevalence of disabilities of Vision, probably because of the use of differing definitions. OPCS learning criteria were judged unsuitable and standard attainment targets (SATs) were substituted. These provided similar prevalence figures to carers and medical records. OPCS behaviour criteria were also unsuitable and were replaced by the General Health and Behaviour Questionnaire (GHBQ). This found an increased prevalence of problems compared with carers and doctors.
Conclusions:
Diagnostic labels have limited use when collecting data about disabled children. Doubt is cast on the validity of some of the 1985 OPCS threshold criteria, and reassessment is suggested before their future use. Further work is needed on the use of SATs and GHBQ in the benchmarking of disability. To collect population data it would be easier and at least equally effective (with caution in the case of Vision) to ask carers directly rather than applying descriptive thresholds and external judgements. Similar information could be obtained from medical records, however, they are likely to be out of date.
