Changing how a person perceives and thinks about others was the most effective intervention for loneliness, a sweeping analysis of previous research has determined. The findings may help physicians and psychologists develop better treatments for loneliness, a known risk factor for heart disease and other health problems.
Recently, researchers have characterized the negative influence of loneliness upon blood pressure, sleep quality, dementia, and other health measures. Those effects suggest that loneliness is a health risk factor, similar to obesity or smoking, which can be targeted to improve patients' health in several dimensions.
"People are becoming more isolated, and this health problem is likely to grow," said John Cacioppo, PhD, Professor of Psychology at the University of Chicago. "If we know that loneliness is involved in health problems, the next question is what we can do to mitigate it."
To determine the most effective method for reducing loneliness, Cacioppo and a team of researchers from the University of Chicago examined the long history of research on the topic. Published in the journal Personality and Social Psychology Review, their quantitative review found that the best interventions targeted social cognition rather than social skills or opportunities for social interaction.
The team's review, called a meta-analysis, analyzed the methods and results from dozens of papers that tested loneliness interventions. Strategies fell into four categories: improving social skills, increasing social support, creating opportunities for social interaction, and addressing social cognition.
When the researchers pooled the 20 studies that employed the most rigorous study design of randomized, controlled trials, they found a small, but significant effect on reducing loneliness. Sub-dividing the studies by their strategy revealed that interventions targeting social cognition a person's thoughts about themsel
