Brief summary

The aim of this study is to measure the impact of the intervention (PAX GBG) in Estonian-language 1st grade classrooms on students' mental health and behaviour, and teacher's self-efficacy.

Detailed description

2-year, matched-pair, cluster-randomized controlled trial with a intervention and wait-list control arm is conducted during school years 2016/17 and 2017/18. 42 volunteering schools were matched to pairs. One school in each pair was randomly selected to receive the PAX GBG or continue their normal activities without intervention. After a post-test assessment in spring 2018 the control group teachers are trained and supported to implement PAX GBG.

Interventions

PAX GBG includes evidence-based kernels and a classroom game where students are reinforced for their mutual success in withholding inappropriate behavior.

Design outcomes

Primary

MeasureTime frameDescription
Change in children's social and emotional well-beingBaseline, 7 months post-baseline and 19 months post-baselineChildren's social and emotional well-being will be measured by the teacher-completed Strengths and Difficulties Questionnaire with impact supplement (SDQ; Goodman, 1999) and parent-rated Strengths and Difficulties Questionnaire (Goodman, 1997).

Secondary

MeasureTime frameDescription
Change in symptoms of attention deficit hyperactivity disorder (ADHD) among the childrenBaseline, 7 months post-baseline and 19 months post-baselineThe Swanson, Nolan and Pelham-IV Questionnaire (SNAP-IV) (Swanson et al., 2001) is an 18-item instrument for rating ADHD-related symptoms and will be completed by parents.
Change in children's behavioral inhibitionBaseline, 7 months post-baselineThe effects of the intervention on inhibitory control will be measured using cognitive task (Go/No-Go task). The task will be developed specially for this research and completed by children.
Change in teachers' sense of efficacyBaseline, 7 months post-baseline and 19 months post-baselineTeachers' efficacy will be measured with The Teachers' Sense of Efficacy Scale (TSES; Tschannen-Moran & Hoy, 2001). It is a self-reported measure for teachers that consists of 24 items and assesses the teacher's perception of their sense of effectiveness as a teacher.
Change in classroom behaviorBaseline, 7 months post-baseline and 19 months post-baselineTeacher-rated 4-item measure will be used to assess classroom behavior. The measure originates from Organisation for Economic Co-operation and Development (OECD) Teaching and Learning International Survey (TALIS) 2013 teacher's questionnaire (question nr 41) and asks to indicate how strongly does the teacher agree or disagree with statements about the classroom behavior.
