Neurodevelopmental disorders and loneliness: School predictors & outcomes. This project aims to establish trajectories of loneliness across the 10-18 year developmental period in adolescents with neuro-developmental disorders (NDDs). This is significant because adolescence is the peak period for loneliness and the social communication difficulties experienced by adolescents with NDDs place them at greater risk of loneliness. Lower levels of school attendance, connectedness and mental well-being, ....Neurodevelopmental disorders and loneliness: School predictors & outcomes. This project aims to establish trajectories of loneliness across the 10-18 year developmental period in adolescents with neuro-developmental disorders (NDDs). This is significant because adolescence is the peak period for loneliness and the social communication difficulties experienced by adolescents with NDDs place them at greater risk of loneliness. Lower levels of school attendance, connectedness and mental well-being, and higher rates of disruptive behaviour, expulsion, drop-out, depression, social withdrawal, and suicide ideation are strongly linked to loneliness. Therefore predicting critical times in trajectories will enhance emotional, behavioural and school related outcomes and optimise economic, societal and quality of life benefits.Read moreRead less
