One of the main conclusions of the study is that children who repeatedly have obsessions and compulsions notably increase their risk of suffering from an OCD-related disorder later in life.
The research used data from the Dunedin Study which has been carried out with citizens of Dunedin, New Zealand since 1973. It is the only place in the world where a long-term followup of different psychological variables has taken place from childhood to adulthood with a sample of one thousand people.
Researchers assessed the evolution of two variables in participants at ages 11, 26 and 32: the repeated presence of obsessive ideas (e.g. recurrent and undesired thoughts to harm others) and compulsive rituals (a need to wash their hands constantly, to check up on small everyday tasks to prevent harm or repeatedly carrying out activities that seem meaningless, etc).
Based on the analysis of these data, researchers for the first time have obtained objective proof that there is a correlation between obsessions and compulsions in childhood (when study members were age 11) and the probability of suffering from an obsessive-compulsive disorder (OCD) as an adult (observed at ages 26 and 32 among participants).
More specifically, the girls and boys in the study who showed symptoms of obsessive or compulsive behavior at 11 — a total of 8 percent of the population studied — were six times as likely than others to suffer from an obsessive-compulsive disorder in adulthood.
“There is nevertheless no need to become alarmed with the cases of children who manifest these symptoms, since they are very common amongst children aged 8 to 10, while the percentage of adults with this disorder does not reach 2 percent.
What should be done is focus on preventive measures for these children, since we’ve seen that the risk is much lower amongst the rest of the population”, Dr. Fullana stated.
According to the authors of the research, theses results can be extrapolated to other populations, even though they were obtained from a sample population in New Zealand, since the characteristics and incidences are similar in other parts of the world.
Obsessive-compulsive disorder is generally accompanied by a family history of this disorder and its treatment has a strong psychological component based on screening prevention strategies, as well as drug therapy based on the administration of antidepressants.
