Children who feel lonely for more than 6 months more likely to have psychosis

Children who felt lonely for more than six months before 12 years of age are more likely to experience an episode of psychosis than children who did not experience loneliness, with women more affected than men, a new study has found. 

 

Psychosis refers to a collection of symptoms that affect a person’s mind, where there has been some loss of contact with reality. During episodes of psychosis people may have challenged separating real from imaginary, with symptoms including hallucinations, delusions and confused thoughts. 

 

In some instances, psychosis may be a symptom of other mental health conditions, such as schizophrenia, bipolar disorder, or severe depression. 

 

Researchers defined loneliness as “the subjective feeling of distress associated with a lack of meaningful relationships, regardless of the amount of social contact,” whereas social isolation was defined as “the objective lack of social contact or support.”

 

Researchers retrospectively assessed the level of loneliness in participants by asking “did you ever feel lonely for more than 6 months before the age of 12 years?” and differentiated this from social isolation by using the ‘peer relationships’ item from the Premorbid Adjustment Scale. 

 

The study sample comprised 285 patients who had experienced their first episode of psychosis and 261 controls.

 

Key findings from the study include:

 

• Loneliness in childhood was associated with an increased likelihood of experiencing a psychotic episode, and this association remained significant after controlling for objective social isolation in childhood.
• The association between loneliness and experiencing a psychotic episode was stronger in women than in men.
• In women who had experienced a psychotic episode, loneliness in childhood was associated with a significantly reduced likelihood of being diagnosed with schizophrenia spectrum disorders relative to other forms of psychosis.
• In those who had experienced a psychotic episode, loneliness in childhood was associated with a greater severity of positive psychotic symptoms as well as affective symptoms (disturbance of mood) and worse functioning.

 

“There is increasing evidence of the negative health and social consequences of loneliness in adults, but much less is known about the long-term effects of loneliness in young people,” Dr Covadonga Díaz-Caneja said. 

 

“Despite their preliminary nature, our results suggest that childhood loneliness may serve as an early risk factor for later psychotic disorders and support its role as a potential target for preventive mental health interventions from an early age. This may be especially relevant considering that childhood loneliness is a prevalent phenomenon that appears to be increasing in recent years”.

 

Fellow researcher Professor Andrea Fiorillo, President Elect of the European Psychiatric Association said the work offers valuable insight into the association between childhood loneliness and first-episode psychosis. 

 

“With the rise of digitalisation and social isolation, loneliness has become a pervasive issue affecting young individuals,” he said. 

 

“The compelling findings of this study, which establish a direct connection between childhood loneliness and the onset of psychosis, highlight a concerning trend and underscore the importance of addressing social connectedness and emotional well-being from an early age.”
