BACKGROUND: Behaviour problems are common in young @entity1 with @entity72 ( @entity72 ). There are many different tools used to measure behavior problems but little is known about their validity for the population. OBJECTIVES: To evaluate the measurement properties of behaviour problems tools used in evaluation of intervention or observational research studies with @entity1 with @entity72 up to the age of six years. METHODS: Behaviour measurement tools were identified as part of a larger, two stage, systematic review. First, sixteen major electronic databases, as well as grey literature and research registers were searched, and tools used listed and categorized. Second, using methodological filters, we searched for articles examining the measurement properties of the tools in use with young @entity1 with @entity72 in ERIC, MEDLINE, EMBASE, CINAHL, and PsycINFO. The quality of these papers was then evaluated using the COSMIN checklist. RESULTS: We identified twelve tools which had been used to measure behaviour problems in young @entity1 with @entity72 , and fifteen studies which investigated the measurement properties of six of these tools. There was no evidence available for the remaining six tools. Two questionnaires were found to be the most robust in their measurement properties, the @entity1 Behavior Checklist and the Home Situations Questionnaire-Pervasive @entity245 version. CONCLUSIONS: We found patchy evidence on reliability and validity, for only a few of the tools used to measure behaviour problems in young @entity1 with @entity72 . More systematic research is required on measurement properties of tools for use in this population, in particular to establish responsiveness to change which is essential in measurement of outcomes of intervention.
