Is there a difference between child self-ratings and parent proxy-ratings of the quality of life of children with a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD)? A systematic review of the literature

There are contemporary indicators that parent proxy-ratings and child self-ratings of a child’s quality of life (QoL) are not interchangeable. This review examines dual informant studies to assess parent–child agreement on the QoL of children with attention-deficit/hyperactivity disorder. A systematic search of four major databases (PsycINFO, MEDLINE, EMBASE and Cochrane databases) was completed, and related peer-reviewed journals were hand-searched. Studies which reported quantitative QoL ratings for matched parent and child dyads were screened in accordance with relevant inclusion and exclusion criteria. Key findings were extracted from thirteen relevant studies, which were rated for conformity to the recommendations of an adapted version of the STROBE statement guidelines for observational studies. In the majority of studies reviewed, children rated their QoL more highly than their parents. There was some evidence for greater agreement on the physical health domain than psychosocial domains

Psychometric properties of the TACQOL-asthma, a disease-specific measure of health related quality-of-life for children with asthma and their parents

The disease-specific-TACQOL-asthma questionnaire measures health-status and appraisal of health-status. The TACQOL-asthma evaluates the personal feelings about problems in the domains, 'complaints, situations, emotions, treatment and medication'. The TACQOL-asthma can be used alone or in combination with the generic TACQOL. Our objective was to study the psychometric properties of the TACQOL-asthma-questionnaire. Responses of 298 parents and children with asthma (age eight to 16 years) in four paediatric practices in the northern part of The Netherlands were studied. The factor-analysis and item-domain correlation analysis show a moderate to strong correlation between the different items and their hypothesised domains. For all items, the correlation of the separate item with the hypothesized domain is stronger than with any other domain. The internal consistency (Cronbach's alpha) of the domains is moderate to good. Concurrent correlation with the Paediatric-Asthma-Quality-of-Life-Questionnaire-(PAQLQ) was significant. Effect sizes of differences between asthma-severity classes in TACQOL-asthma and PAQLQ-scores were similar and of clinical importance. This study validates the TACQOL-asthma as a new disease-specific questionnaire. The TACQOL-asthma ensures a measurement of health status as well as appraisal of health problems. The TACQOL-asthma has good reliability and validity properties to serve as an evaluative and discriminate disease-specific health-related-quality-of-life questionnaire
