Less aggressive thanks to stronger relationships

'In moments when someone was sad or in pain, how often have you tried to comfort them?' 'How often have you hit, kicked or bitten other people?' Using these questions and others like them, researchers from the z-proso longitudinal study investigated to what extent schoolchildren were behaving either prosocially or aggressively. During the course of the study, scientists assessed over 1,400 children living in Zurich at regular intervals, starting from their first year of primary school in 2004. They also asked parents and teachers about the children¡¯s behaviour. Even if the various interviewees¡¯ perceptions didn¡¯t necessarily agree, researchers were able to collect a vast amount of data and use this to create a profile of each individual child.

Changes of teacher as a starting point

Researchers used these detailed profiles of the children's social conduct to establish how individual factors can influence behaviour. In this case, the researchers wanted to examine the effect of the teacher-student relationship. To this end, roughly 600 pairs were selected from among the 1,400 children. For purposes of comparison, each pair's profile was similar except for one key detail: the positive or negative quality of their relationship with their teacher. The pairs were created when the children were roughly 10 years old, just before they moved from primary to secondary school (between the third and fourth years of the Swiss primary school system). In the Zurich school system, there is a change of teacher at this point. After the change of teacher, the researchers used the aforementioned standardised questionnaire to examine the children¡¯s relationship with their new teacher to see whether those with a positive relationship differ from those with a negative relationship with their teacher.

38% less aggressive behaviour

The results are extremely clear: children who had a good relationship with their teacher demonstrated a greater degree of prosocial behaviour and were also more altruistic and empathetic, as well as less aggressive. Pupils who had a positive relationship with their teacher demonstrated 18% more prosocial behaviour and up to 38% less aggressive behaviour on average than children with ambivalent or negative relationships with their teacher. 'The idea that a pupil¡¯s relationship with their teachers has an influence on their behaviour is something we were expecting,' explains principal investigator Manuel Eisner, from the University of Cambridge. 'What we didn't expect was how strongly the relationship influenced children¡¯s behaviour.' The study¡¯s design goes far beyond simple correlations such as 'good students like their teachers' and vice-versa, and makes it possible to isolate and investigate the effects of the teacher-student relationship.             

Explanations based on other factors such as cultural differences, gender, parenting style, and earlier behavioural problems could therefore be ruled out. 'Although we focused on schoolchildren from Zurich, based on our procedure and the fact that other studies with younger children have produced similar results, we believe our conclusions can be generalised,' explains Denis Ribeaud, who was co-leader of the study and responsible for data collection at ETH Zurich.

More effective than prevention programmes

Two aspects of the longitudinal study particularly surprised the researchers. The first was that positive effects observed at the age of ten were still evident four years later, after another change of teacher, and so had been maintained for a relatively long time. The second was that a positive teacher-student relationship contributed at least as strongly to the development of positive behaviour as established violence prevention programmes ¨C if not more strongly. 'These programmes are very good, and in our view indispensable. Our results should nonetheless influence teacher training and development ¨C that way we can make violence prevention even more effective,' Eisner explains.
