Impact of loneliness on adolescents’ mental health varies between schools

New research finds link between loneliness and adolescent mental health.

24 January 2023

Loneliness is strongly linked with poorer mental health in adolescents, with the impact of loneliness on adolescents' mental health varying depending on the school they attend, a study has found.

Published in the British Journal of Educational Psychology, the research is thought to be the first to explore the association between loneliness and mental health in schools. It identifies that school-based interventions targeting mental health may be especially necessary among lonely adolescents, and says programmes aimed at tackling loneliness may be more beneficial in schools with poorer mental health.

The Scottish research analysed pre-existing data on 5,286 pupils with an average age of 13-and-a-half at 208 schools. Just over half the sample were girls.

It found that loneliness had the most impact on adolescents' mental health in schools with average lower mental health scores.

In addition, for adolescents who are extremely lonely, the school they attend matters more for their mental health, as compared to less lonely peers, where the school they attend has less of an impact on their mental health.

Lead researcher Dr Claire Goodfellow, a chartered member of the British Psychological Society and research associate at the University of Glasgow, said:

“Our findings highlight that while loneliness is typically associated with poorer mental health among adolescents, the nature of this association differs depending on the school a young person attends.

“In a school where average mental health tends to be lower, the negative impact of loneliness on mental health is stronger than at schools where the average mental health is higher.

This means that schools which aim to foster positive mental health among students may also have a positive impact in reducing loneliness. Schools play an important role in the potential to minimise loneliness among young people, and therefore improving their mental health.”

The study adds to the body of literature emerging on the links between loneliness and adolescent mental health, and how the links between the two vary in different school settings.

It also establishes links between mental health and demographic, social and other school factors, such as relationships with teachers.

It found that an improved school climate, including supportive teacher relationships, and increased sense of belonging, can bolster adolescent mental health and the evidence that an over-emphasis on academic achievement may be detrimental to mental health. Family support may also may be of key importance in supporting the mental health of young teenagers.

The study adds to the debate around social media use and mental health in adolescence with links found between increased frequency of online contact with friends and others, and a preference for online communication with poorer mental health.

Although researchers established differences among schools in the association between loneliness and mental health, they were unable to establish which school-level factors were associated with these differences.

However, previous research has found that school-level factors such as urban location, higher percentage of free school meals, and a higher percentage of White British students were associated with poorer pupil mental health (Ford et al., 2021), the paper reveals.

It says future research should aim to explore the contextual environment of schools to more fully understand the factors impacting on adolescents’ mental health.
