Summary: A new study reveals how the mood of one friend can impact the moods of others in their social circle.

Study suggests that depression doesn’t have the same effect.
New research suggests that both good and bad moods can be ‘picked up’ from friends, but depression can’t.
A team led by the University of Warwick has examined whether friends’ moods can affect an individual therefore implying that moods may spread across friendship networks.
The team analysed data from the National Longitudinal Study of Adolescent to Adult Health which incorporates the moods and friendship networks of US adolescents in schools. Their paper Spreading of components of mood in adolescent social networks has been published in the journal Royal Society Open Science. The team’s findings imply that mood does spread over friendship networks, as do various different symptoms of depression such as helplessness and loss of interest. However they also found that they also found that the effect from lower or worse mood friends was not strong enough to push the other friends into depression.
Using mathematical modelling they found that having more friends who suffer worse moods is associated with a higher probability of an individual experiencing low moods and a decreased probability of improving. They found the opposite applied to adolescents who had a more positive social circle.
Public health statistics researcher Rob Eyre led the study. He said: “We investigated whether there is evidence for the individual components of mood (such as appetite, tiredness and sleep) spreading through US adolescent friendship networks while adjusting for confounding by modelling the transition probabilities of changing mood state over time.
“Evidence suggests mood may spread from person to person via a process known as social contagion.
“Previous studies have found social support and befriending to be beneficial to mood disorders in adolescents while recent experiments suggest that an individual’s emotional state can be affected by exposure to the emotional expressions of social contacts.
“Clearly, a greater understanding of how changes in the mood of adolescents are affected by the mood of their friends would be beneficial in informing interventions tackling adolescent depression.”
The World Health Organisation has estimated that depression affects 350 million people across the world, impacting on individual’s abilities to work and socialise and at worse leading to suicide. This study’s findings emphasise the need to also consider those who exhibit levels of depressive symptoms just below those needed for a diagnosis of actual depression when designing public health interventions.
The study also helps confirm that there is more to depression than simply low mood. At the individual level, these findings imply that following the evidence-based advice for improving mood, e.g. exercise, sleeping well, and managing stress, can help a teenager’s friends as well as themselves. Whilst for depression, friends do not put an individual at risk of illness so a recommended course of action would be to show them support.
Their conclusions link in to current policy discussions on the importance of sub-threshold levels of depressive symptoms and could help inform interventions against depression in senior schools
Co-author, professor Frances Griffiths of Warwick Medical School said: “The results found here can inform public health policy and the design of interventions against depression in adolescents. Sub-threshold levels of depressive symptoms in adolescents is an issue of great current concern as they have been found to be very common, to cause a reduced quality of life and to lead to greater risk of depression later on in life than having no symptoms at all.
“Understanding that these components of mood can spread socially suggests that while the primary target of social interventions should be to increase friendships because of its benefits in reducing of the risk of depression, a secondary aim could be to reduce spreading of negative mood.”

Spreading of components of mood in adolescent social networks
Recent research has provided evidence that mood can spread over social networks via social contagion, but that, in seeming contradiction to this, depression does not. Here, we investigate whether there is evidence for the individual components of mood (such as appetite, tiredness and sleep) spreading through US adolescent friendship networks while adjusting for confounding by modelling the transition probabilities of changing mood state over time. We find that having more friends with worse mood is associated with a higher probability of an adolescent worsening in mood and a lower probability of improving, and vice versa for friends with better mood, for the overwhelming majority of mood components. We also show, however, that this effect is not strong enough in the negative direction to lead to a significant increase in depression incidence, helping to resolve the seeming contradictory nature of existing research. Our conclusions, therefore, link in to current policy discussions on the importance of subthreshold levels of depressive symptoms and could help inform interventions against depression in high schools.
