The Early Years Toolbox's (EYT) Child Self-Regulation & Behaviour Questionnaire (CSBQ) is a teacher- or parent-report questionnaire consisting of 34 items relating to children’s everyday behaviours. These items combine to assess children’s self-regulation and social development (e.g., ‘persists with difficult tasks’ and ‘waits their turn in activities’). For each item the respondent selects one of five options to indicate whether the statement is ‘Not true’ to ‘Very true’ about the child. This takes up to 5 minutes per child to complete. CSBQ produces both self-regulation (i.e., behavioural, cognitive and emotional) and social development sub-scales (e.g., prosocial). Subscale scores are presented on the final assessment screen. For more precise research applications, there are options to have the item by item data sent to a user-specified e-mail address or database.
