Being optimistic is good for your health

11 January 2011

Being optimistic does make a difference in teen mental health and behaviour, especially against the onset of depressive symptoms, according to a study by the Murdoch Childrens Research Institute.

A study, published in Pediatrics, assessed 5634 students aged 12 to 14 years over three years on optimistic thinking style, emotional problems, substance use and antisocial behaviours.

Levels of optimism in boys remained stable but in girls there were marked falls in optimism across the study.

At any given time, optimistic teens were doing much better in terms of health risks. Most importantly, risks for the later onset of depression in adolescents who reported high levels of optimism were almost half those of the least optimistic.

Optimism was also protective against the onset of substance abuse and antisocial behaviours such as theft, interpersonal violence and property damage.

Lead researcher Professor George Patton said that that although optimism is protective against adolescent health risks, it is not a panacea.

"Preventive interventions will also need to address other aspects of psychological and interpersonal functioning as well as the social circumstances in which younger teens are growing up," he said.
