YS_TRF7

The survey for the primary school teachers includes items on the teacher, class and school, functioning of the child, school performance, bullying and victimization (from 2010), and standardized questionnaires on problem behavior, namely the Teacher Report Form (TRF), the short version of the Conners’ Teacher Ratings Scale - Revised (CTRS-R), and the Social Skills Rating System (SSRS) (from 2017). Parents of twins, that are approximately 7 (in 2009 age 6) are contacted to ask for their permission to approach the teacher(s). From 2006 onwards, the consents to approach a teacher was extended to the non-twin siblings (6-12 years) of their twins, and from 2009 with consents for triplets.
