Results were then subject to review using a quality appraisal
tool and a narrative synthesis methodology. A theoretical framework was developed for the synthesis
using concepts from mental health and communication studies literature.
Results: Systematic searching retrieved 43 original research papers investigating or exploring the effects of online
technologies on adolescent mental well-being or related concept(s). The benefits of using online technologies
were reported as increased self-esteem, perceived social support, increased social capital, safe identity experimentation
and increased opportunity for self-disclosure. Harmful effects were reported as increased exposure
to harm, social isolation, depression and cyber-bullying. The majority of studies reported either mixed or no effect(
s) of online social technologies on adolescent wellbeing.
Conclusions: This systematic narrative review has revealed contradictory evidence while revealing an absence of
robust causal research regarding the impact of social media on mental wellbeing of young people. Online technologies
are increasingly being used for health and social care purposes, but further research is required to
give confidence that these are appropriately designed to promote the mental health care and support of young
people
