School connectedness is commonly defined as an academic environment in which students believe that adults and peers in the school care about them as individuals. School connectedness is a known protective factor against risky health behaviours and adverse mental health outcomes and is a driver of students’ academic performance. School connectedness is also a key factor that influences students’ prosocial behaviours and the development of their social skills. Previous research conducted in schools in Nyarugusu refugee camp has revealed that teachers report high levels of empathy towards their students and interest in their ideas and perspectives; however, student do not appear to know or perceive such interest and attention. We will assess whether a brief messaging intervention aimed at fixing this gap in perceptions between students and teachers affects student's pro-social behaviours and attitudes.

Experimental Details
The experiment is embedded into an existing study. The intervention consists in a brief message individually delivered to students by enumerators during the administration of the endline survey of the Preventing Violence Against Children (PVAC) study. The content of the message will be the following "We interviewed a lot of teachers in your school and we found out that most of them really care about their students. Nearly all teachers told us that they are really interested in understanding your’ ideas, problems and opinions".

Primary Outcomes
Primary Outcomes (end points)
The primary outcome will be a measure of student's pro-social behavious elicited through the following question "If I told you that a classmate of yours is feeling sad because they are alone and they are looking for a friend to play with after school hours, would you volunteer to spend time with him/her?"
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
Secondary outcomes will be pro-social behaviour measured through the Strengths and Difficulties Questionnaire (SDQ) prosocial subscale.

Experimental Design
Experimental Design
All students particpating in the PVAC endline survey will be individually randomised in a 1:1 ratio to either:
a treatment group that will received the message inserted in the PVAC survey,
a control armgroup that will receive the survey without any additional message.

Randomisation will be stratified by school.
