Child and Adolescent Intellectual Disability Screening Questionnaire to identify children with intellectual disability.

AIM: To evaluate the psychometric properties of the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) in paediatric neurodevelopment clinics. METHOD: Participants were 181 children (aged 6-18y) attending paediatric services in Scotland, divided into three age groups according to previous CAIDS-Q standardization cut-off scores. Fifty-four children (37 males, 17 females; mean age 117mo [SD 29.9mo]) met the criteria for intellectual disability and 127 did not (88 males, 39 females; mean age 120.1mo [SD 32.7mo]). A number of psychometric properties of the CAIDS-Q were evaluated, including test-retest and interrater reliability, convergent validity, sensitivity, specificity, and positive and negative predictive values based on existing cut-off scores. RESULTS: Significant positive relationships were found for all three age groups between CAIDS-Q scores and measures of intellectual and adaptive functioning. Test-retest reliability ranged from 'moderate' to 'almost perfect', whereas interrater reliability ranged from 'fair' to 'almost perfect'. Sensitivity and positive predictive value were 100% for all groups and specificity was between 83% and 94%, depending on age. Negative predictive values ranged from 75% to 91%. INTERPRETATION: The CAIDS-Q appears to show psychometric properties that support its use as a screen for intellectual disability in paediatric neurodevelopmental settings. WHAT THIS PAPER ADDS: The Child and Adolescent Intellectual Disability Screening Questionnaire showed good psychometric properties. It identified all participating children who met the criteria for intellectual disability. Between 83% and 94% of children without intellectual disability were also correctly identified.

CUESTIONARIO DE PESQUISA DE DISCAPACIDAD INTELECTUAL EN NIÑOS Y ADOLESCENTES PARA IDENTIFICAR DISCAPACIDAD INTELECTUAL: OBJETIVO: Evaluar las propiedades psicométricas del Cuestionario de Detección de Discapacidad Intelectual en Niños y Adolescentes (CAIDS-Q, siglas en inglés) en clínicas pediátricas de neurodesarrollo. MÉTODO: Participaron 181 niños (de 6 a 18 años) que asistían a servicios pediátricos en escocia, divididos en tres grupos de edad de acuerdo con los puntajes de corte de estandarización para la CAIDS-Q. Cincuenta y cuatro niños (37 varones, 17 mujeres, edad media 117 meses (DS 29.9 meses) cumplían con los criterios de discapacidad intelectual y 127 no cumplían con los criterios estipulados (88 varones, 39 mujeres, con una edad media de 120,1 meses (DS 32,7 meses). Se evaluaron varias propiedades psicométricas del CAIDS-Q, incluidas la repetibilidad y la confiabilidad entre evaluadores, la validez convergente, la sensibilidad, la especificidad y los valores predictivos positivos y negativos basados en los puntajes de corte preexistentes. RESULTADOS: Se encontraron correlaciones positivas significativas para los tres grupos de edad entre los puntajes CAIDS-Q y las mediciones de funcionamiento intelectual y adaptativo. La confiabilidad test-retest (repetibilidad) fue de 'moderada' a 'casi perfecta', mientras que la confiabilidad entre evaluadores fue de 'buena' a 'casi perfecta'. La sensibilidad y el valor predictivo positivo fueron del 100% para todos los grupos y la especificidad fue del 83% al 94%, según la edad. Los valores predictivos negativos fueron del 75% al ​​91%. INTERPRETACIÓN: El CAIDS-Q parece mostrar propiedades psicométricas que respaldan su uso como instrumento de pesquisa para la discapacidad intelectual en contextos de neurodesarrollo pediátrico.

QUESTIONÁRIO DE RASTREIO DE DEFICIÊNCIA INTELECTUAL DA CRIANÇA E DO ADOLESCENTE PARA IDENTIFICAR CRIANÇAS COM DEFICIÊNCIA INTELECTUAL: OBJETIVO: Avaliar as propriedades psicométricas do Questionário de Rastreio da Deficiência Intelectual da Criança e do Adolescente (CAIDS-Q) em clínicas de neurodesenvolvimento pediátrico. MÉTODO: Os participantes foram 181 crianças (idades 6-18 anos) que frequentam serviços pediátricos na Escócia, divididos em três grupos etários de acordo com pontos de corte da padronização do CAIDS-Q. Cinquenta e quatro crianças (37 do sexo masculino, 17 do sexo feminino; média de idade 117m [DP 29,9m]) atenderam aos critérios para deficiência intelectual e 127 não atenderam (88 do sexo masculino, 39 do sexo feminino; média de idade 120,1m [DP 32,7m]). Um número de propriedades psicométricas do CAIDS-Q foram avaliadas, incluindo confiabilidade teste-reteste e entre examinadores, validade convergente, sensibilidade, especificidade, e valores preditivos positivos e negativos, com base em pontos de corte existentes. RESULTADOS: Relações positivas significativas foram encontradas para todos os três grupos etários entre os escores CAIDS-Q e medidas de funcionamento intelectual e adaptativo. A confiabilidade teste-reteste variou de "moderada" a "quase-perfeita", enquanto a confiabilidade entre examinadores variou de "leve" a "quase perfeita". Os valores de sensibilidade e valores preditivo positivos foram 100% para todos os grupos, e a especificidade variou de 83% a 94%, dependendo da idade. Valores preditivos negativos variaram de 75% a 91%. INTERPRETAÇÃO: O CAIDS-Q parece mostrar propriedades psicométricas que sustentam seu uso para rastrear deficiência intelectual em ambientes de neurodesenvolvimento pediátrico.

Screening for intellectual disability with the Child and Adolescent Intellectual Screening Questionnaire: a modified Delphi approach.

AIM: To develop a consensus framework to evaluate the impact of screening for intellectual disability, using the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) in paediatric neurodevelopment clinics. METHOD: A modified Delphi survey with four phases (literature review; initial development of framework [participants=11 parents, 8 professionals]; qualitative interviews [participants=4 parents, 15 professionals]; questionnaire development [participants=31 parents, 14 professionals] was used to develop the consensus framework. The framework was used to evaluate the impact of screening on six paediatricians and 31 parents of children who had participated in a previous paediatric screening project. RESULTS: Twelve of the original 20 items were retained based on levels of endorsement of 60 per cent or above. Direct benefits of using the CAIDS-Q were: indicating the child's level of functioning, increasing awareness of intellectual disability, helping to identify children with intellectual disability, and identifying potentially vulnerable children. Benefits related to subsequent diagnostic assessment were: promoting greater understanding of the child, identification of support needs, and receipt of support, particularly for the child at school. INTERPRETATION: The use of the CAIDS-Q had a number of direct and indirect benefits for children, families, and services as reported by parents and paediatricians. WHAT THIS PAPER ADDS: A 12-item framework was developed to evaluate the impact of screening for intellectual disability. Direct benefits of the Child and Adolescent Intellectual Disability Screening Questionnaire include increasing awareness and identification of intellectual disability. Indirect benefits included increased identification of support needs and receipt of support.
