In the current study a multi-dimensional scale that measures teacher autonomous behaviour is presented. The scale is applicable across the following educational sectors: primary education, secondary education and vocational education. Based on an elaborate literature study, four theoretically relevant dimensions of teacher autonomous behaviour…

While various screening instruments for autism spectrum disorders are widely used in diagnostic assessments, their psychometric properties have not been simultaneously evaluated in the outpatient setting where these instruments are used most. In this study, we tested the Ritvo Autism Asperger Diagnostic Scale-Revised and two short versions of the…

The present study examines the development of a measure tapping students' perceptions of (pre-service) teachers' teaching behaviour to explore the practical value of such a measure in teacher education and teacher professional development programs. From a sample of 1,635 students of 91 pre-service teachers teaching in secondary education in The…

The factor structure, internal consistency, construct validity, and predictive validity of the Dutch version of the Five Facet Mindfulness Questionnaire (FFMQ-NL) were studied in a sample of meditators (n = 288) and nonmeditators (n = 451). A five-factor structure was demonstrated in both samples, and the FFMQ-NL and its subscales were shown to…

Recently, Gotham et al. ("2007") proposed revised algorithms for the Autism Diagnostic Observation Schedule (ADOS) with improved diagnostic validity. The aim of the current study was to replicate predictive validity, factor structure, and correlations with age and verbal and nonverbal IQ of the ADOS revised algorithms for Modules 1 and 2…

In this study, psychometric properties of the Health of the Nation Outcome scales (HoNOS) and Health of the Nation Outcome Scales for People with Learning Disabilities (HoNOS-LD) were investigated in a sample (n = 79) of (young) adults with mild to borderline intellectual disability (ID) and severe behavior and mental health problems who were…

To be able to offer children with developmental disorders adequate help, professionals working in special needs education must use a screening device to assess the specific psychiatric difficulties of the children. In this paper the psychometric properties of an easy-to-use parental rating scale to screen symptoms of major psychiatric disorders…

A pilot study examined the reliability and predictive validity of a screening instrument for Dutch kindergartners. Findings indicated acceptable reliability and predictive validity. Parents could accurately screen their child's language proficiency level, pre-arithmetic level, and degree of extraversion at school entry. Teachers could predict…
