Loneliness patterns across time and subsequent risk of psychotic experiences, depression, anxiety, and diminished well‐being in adolescents
BACKGROUND: Evidence on the association between loneliness and psychotic experiences in adolescents remains limited. Moreover, loneliness has typically been assessed at a single time point, which fails to capture its dynamic nature. We hypothesized that persistent loneliness, assessed across repeated measures, would be associated with psychotic experiences and other mental health problems. METHODS: Using longitudinal data from 3,171 participants …
Peer-friendship Networks and Self-harm among Adolescents from Inner-city Schools
Peer-relationships are critically important for adolescent behavior, but how peer-friendship network composition and structure influence adolescent self-harm is less clear. The aim of this cross-sectional study was to explore the association between in-school peer-friendship networks, gender, and self-harm among inner-city adolescents. Participants were 2203 adolescents (mean age = 12.5 years, SD = 1.0; 53% girls) attending inner-city south Londo…
Using digital qualitative diaries to understand how socioeconomic disadvantage shaped young people’s academic experiences and mental health during the Covid-19 pandemic

The silent crisis in girls' mental health
Qualitative Digital Diary Methods
Qualitative digital diary methods are a promising tool for capturing participants' experiences in their own words and over time. The use of smartphone apps to collect this kind of data provides an accessible and flexible way to participate in research, but to truly benefit from this method, participants needs and preferences must be taken into account. This paper explores participants' experiences of taking part in qualitative digital diary resea…
Covid‐19, social restrictions, and mental distress among young people
BACKGROUND: Adolescence is a critical period for social and emotional development. We sought to examine the impacts of Covid-19 and related social restrictions and school closures on adolescent mental health, particularly among disadvantaged, marginalised, and vulnerable groups. METHODS: We analysed four waves of data - 3 pre-Covid-19 (2016-2019) and 1 mid-Covid-19 (May-Aug 2020; n, 1074; 12-18 years old, >80% minority ethnic groups, 25% free sch…
Prevalence of conduct problems and social risk factors in ethnically diverse inner-city schools
Conduct problems are markedly more common in inner-city schools, and variations in the prevalence of conduct problems are, to some extent, rooted in modifiable social contexts and experiences, such as experiences of racial discrimination
Mental distress among young people in inner cities
BACKGROUND: Recent estimates suggest around 14% of 11-16 years in England have a mental health problem. However, we know very little about the extent and nature of mental health problems among diverse groups in densely populated inner cities, where contexts and experiences may differ from the national average. AIMS: To estimate the extent and nature of mental health problems in inner city London, overall and by social group, using data from our s…
Body size dissatisfaction among young Chinese children in Hong Kong
Objective To determine the potential predictors of body size dissatisfaction in Chinese children. Design The Child’s Body Image Scale was used to assess body size perception and dissatisfaction. BMI was calculated from objectively measured height and weight. Predictors of body size dissatisfaction were examined by logistic regression analysis. Setting Hong Kong, China. Subjects Six hundred and twenty children (53 % boys, aged 6·1–12·9 years) from…
Fitness, physical activity and BMI in 5- to 6-year-old children; cross-sectional analysis on a sub-sample of children from the Waves study, UK
Do children emotionally rehearse about their body image
This study examined the association between propensity for emotional rehearsal, body image self-perception and weight status in Chinese Hong Kong pre-adolescents. Children 8-12 years of age ( n = 278) completed measurement of body mass index, body image and emotional rehearsal. Multinomial regression analyses revealed that body mass index was positively associated with body image dissatisfaction and a significant predictor of body size estimation…
