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

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 (ß=0·3448, p<0·0001), subjective wellbeing (ß=0·3075, p<0·0001), and a reduction in negative mood (ß=-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. FUNDING: Taibah University.

Association between friendship quality and subjective wellbeing among adolescents: a systematic review.

BACKGROUND: Social integration with friends has an important role in shaping adolescents' behavior and determining their wellbeing. Friendship features such as companionship, trust, closeness, intimacy, and conflicts all form the concept of friendship quality. The quality of friendships can either enhance or impede mental development during adolescence. Therefore, this systematic review was conducted to understand the association between friendship quality and adolescents' mental wellbeing. METHODS: In November 2020 and later in August 2022, the search for evidence was conducted on five databases (Medline, Embase, ProQuest, Scopus, and PsycINFO). Only peer-reviewed quantitative studies published from January 2000 to August 2022 that investigated friendship quality as their exposure variable in relation to six constructs of subjective wellbeing (mood, loneliness, life satisfaction, happiness, self-esteem, and subjective wellbeing) were included. After screening for eligibility, two reviewers independently extracted the data based on population characteristics, study design, exposure and outcome variables, outcome measures used, and results. Risk of bias assessment was performed utilizing the NIH Quality Assessment Tool. Narrative evidence synthesis was performed based on the constructs of subjective wellbeing. RESULTS: Forty-three articles out of 21,585 records were included in the review. The relationship between friendship quality and depression has been investigated extensively in the literature and negative (beneficial) associations were found in eighteen studies out of twenty-three. Poor peer relationship was associated with loneliness in nine studies out of ten. All seven studies on life satisfaction and quality of peer connection found a positive association. In five studies, better peer relationship was found to be associated with happiness. A positive association between friendship quality and self-esteem was observed in five out of six applicable studies. Friendship quality was found to be positively associated with subjective well-being in all of five included studies. CONCLUSIONS: Although majority of the included studies were cross-sectional in nature, this review demonstrates the paramount value of promoting healthy friendship to adolescents' subjective wellbeing constructs. Interventions that aim to promote subjective wellbeing among adolescents should consider the development and maintenance of healthy friendships.
