What works in interventions targeting loneliness: a systematic review of intervention characteristics.

Group sessions seem preferred to individual formats, and interaction through active participation and group or facilitator contact appear beneficial, however studies also recognised the importance of a person-tailored approach to delivery. Studies suggest there is no 'quick fix' to loneliness, but that learnt practices, behaviours, and community connection should be built into one's lifestyle to achieve sustained intervention effectiveness. Future interventions should consider longer follow-up periods, male and populations with lower educational levels.
