Association between friendship quality and subjective wellbeing in adolescents: a cross-sectional observational study

Abstract

Background: Friendships play a vital role in the social lives of teenagers, and friendship quality can substantially impact the adolescents' overall health and wellbeing. This study aimed to investigate the association between friendship quality and subjective wellbeing in Northern Irish adolescents.

Methods: In this cross-sectional observational study, we used data from the second wave of the Wellbeing in Schools Survey, conducted in Northern Ireland from April 2 to May 31, 2018. This survey used a clustering sampling method and included students aged 15-19 years. The survey was approved by the School of Social Sciences, Education and Social Work's Research Ethics Committee, with pupil opt-in and parental opt-out consents. Participants from the survey's initial wave in 2016 were considered eligible. Data on friendship quality and classroom friendships were gathered. Subjective wellbeing was assessed using the 7-item Short Warwick-Edinburgh Mental Wellbeing Scale. Metrics for psychological wellbeing (6 items), mood (7 items), and friendship quality (6 items) were taken from the KIDSCREEN-52 questionnaire. All items were rated on a 1-5 point Likert scale. We examined the association between friendship network quality and subjective wellbeing outcomes through social network analysis and network autocorrelation modelling.

Findings: Of 1542 students invited, 1189 (77%) from 83 schools responded to the friendship network queries. Slightly more than half of these participants were female (609 [51%] girls and 580 [49%] boys), and the median age was 16 years (range 14-19, IQR 16-16). The median overall friendship score stood at 20 (IQR 18-26, with possible scores ranging from 6 to 30). Adjusted network autocorrelation models indicated that higher friendship quality scores were significantly associated with improved psychological wellbeing (β=0·3448, p<0·0001), subjective wellbeing (β=0·3075, p<0·0001), and a reduction in negative mood (β=-0·1934, p<0·0001).

Interpretation: The study found that friendship quality had a significant association with mood, psychological wellbeing, and subjective wellbeing in adolescents. The results emphasise the value of fostering positive social relationships among adolescents, with a particular focus on the quality of their friendships. Next stages of this research include longitudinal analysis to test these associations more robustly.
