Suicide behaviour in social circles increases risk for Kenyan men

Suicide is increasingly recognised as a global health challenge by the World Health Organisation who call for society-wide efforts to prevent suicide.

In a recent study, we set out to understand the drivers of suicide for young men in Meru county, in central Kenya. We wanted to know whether young men in the region were more at risk of contemplating suicide if they have more friends and family who have attempted, or committed, suicide.

Previous research has found that incidents of suicide and emotional states contribute to suicidal thoughts passing among networks of friends and within families. Part of the familial link may be genetic, but evidence shows that social pathways – like the transmission of considering suicide as a viable option and devaluing one’s own life as a result of a peer’s self destructiveness – also exist.

If we identify factors that predict why young men consider suicide as an option, we can potentially stop suicides before they happen.

Contemplating suicide

Using surveys, we randomly interviewed 514 young men (aged 18-34 years) in the Igembe sub-counties of Meru County. We used the Modified Scale of Suicide Ideation – a scale that assesses the presence or absence of suicidal thoughts and how severe suicidal ideas are – and coded for only the most severe cases.

We found that, over two days, around 12% of men engaged in severe suicide ideation – they prepared a plan to end their lives, and considered their own death with concerning intensity or frequency. Though global lifetime estimates of considering suicide range between 14%-33%, our survey specifically screened for more severe suicide ideation, as opposed to more common passing thoughts about ending one’s life.

Among young men who reported that none of their friends had completed suicide, the percentage who had contemplated suicide was 5%. This is much lower than the percentage of respondents who engaged in severe suicidal ideation if they had one friend who completed suicide (17%), and higher still if respondents knew two or more friends who completed suicide (32%).

Similarly, the prevalence of suicidal thoughts increases with the number of friends who attempt, but don’t complete, suicide. If a family member completed suicide during the respondent’s first 18 years of life, the risk for present suicidal thoughts increases by 20% in the respondent’s young adulthood. These patterns are consistent regardless of education, age and household wealth.


Consistent with other studies, we found a relationship between self-esteem, loneliness and suicide that may explain this pattern. Men who reported more suicide among friends and family, reported lower social self-esteem, a predictor of suicide behaviour. Men who reported lower self-esteem also reported more loneliness – described as the pain felt when they believed they didn’t belong socially and emotionally.

The image is therefore that men who have experienced suicide in their social groups think their social groups are less valuable and experience loneliness. They then experience less meaning in life and thoughts of ending their own life can begin to form.

Prior research also finds that our thoughts about ourselves are influenced by the self destructive behaviours of our peers. We can internalise their emotions and behaviours as though these emotions and behaviours were our own through a process called projective identification.

Peer suicide doesn’t affect the majority and identifying social and psychological factors that lead to resistance needs more investigation, and likely includes making meaning from the tragedy.


The implications of this research are multi-fold.

As with many countries, Kenya lacks enough mental health resources to meet the demand for services. Resources to prevent suicide in the future should target young men who are friends or children of those who have attempted or completed suicide in the past. This includes identifying and following-up with friends of suicide attempters who come to emergency health centres.

Efforts should focus on group support and gratitude interventions which encourage people to remember at least one thing they are thankful for each day by writing or drawing it down. Gratitude interventions can improve one’s sense of meaning in life and reduce suicidal thoughts.

Faith, community, education and other leaders should be sensitised to the challenges faced by those who remain behind after a loved one’s suicide.

And finally, media campaigns should be promoted that improve awareness and reduce stigma related to mental health issues.
