The study, conducted at the Ontario Science Centre, looked at more than 1,000 children and adolescents from ages eight to 18. While boys and girls reported the same frequency of persistent pain – lasting three months or more – teenage girls experienced more anxiety and tended to catastrophize over pain to a greater degree than their male peers.  

“Boys who experience pain may feel less comfortable expressing their feelings because they are deemed socially inappropriate – or it may be that boys simply experience less anxiety in relation to pain,” says study lead author Samantha Fuss (MA ’10), a PhD student in psychology at 91ŃÇÉ«. “Even teenage girls who haven’t experienced persistent pain showed significantly higher levels of pain anxiety than boys their age.”   

Overall, 27 per cent of participants reported experiencing persistent pain. The study is published in the latest issue of the journal .

Study co-author Joel Katz, a 91ŃÇÉ« psychology professor and , says more research is needed to understand the psychological factors relating to pain in youth.

“Persistent pain in children and teenagers isn’t a rare occurrence. There are gaps in our understanding of the time course of pain and the developmental trajectories,” Katz says. “For example, how does the presence of pain in these life stages relate to pain in adulthood?”

Researchers looked at psychological variables including anxiety, anxiety sensitivity and pain catastrophizing – a tendency to worry about pain and feel helpless in the face of it.

Boys 12 to 18 years of age were significantly more likely to experience persistent pain than younger boys, while there was no difference between age groups for girls.

Fuss points out that girls more frequently seek medical attention for illness and pain than do boys – which makes their findings all the more intriguing.

“Our sample wasn’t drawn from a clinical setting – such as interviewing patients at a walk-in clinic,” she says. “This is a fairly representative sample of Toronto children and adolescents who happened to be visiting the Science Centre with their parents.”

Katz notes that the greater prevalence of chronic pain in women versus men may be tied to psychological factors that appear in childhood.

“Anxiety sensitivity is thought to be a vulnerability factor for the development of chronic pain. The finding that girls had higher levels of anxiety sensitivity than boys may partly explain why the prevalence of chronic pain is greater in women than men,” he says.

“It’s a complex web to untangle in terms of physical versus psychological,” says Fuss. “Is it that the psychological experience of pain differs between the sexes – or even age groups – or is it differences in the physical experience of pain? How are they linked? These are certainly important questions in terms of diagnosis and pain management.”

Fuss’ research is supervised by Katz. Their work is funded by a Canadian Institutes of Health Research Canada Graduate Scholarship to Fuss, and a Canada Research Chair in Health Psychology to Katz.

The award is, in part, based on the researcher’s record of early career achievement. For Weiss, that encompasses the research on developmental disabilities that he’s conducted over the last three or more years. He is one of two recipients of the award this year, handed out by the CPA.

“The award is really recognition for the type of research I’ve been able to do prior to and since beginning at 91ŃÇÉ«,” says Weiss, a clinical psychologist in 91ŃÇɫ’s Department of Psychology, Faculty of Health. “It’s been great to be recognized by psychologists, not just in the field of developmental disabilities, but by colleagues from other fields.”

He is co-investigator for three Canadian Institutes of Health Research-funded projects, two of which look at children with developmental disabilities and the third at understanding pathways to emergency health care for adolescents and adults with Autism Spectrum Disorder.

Weiss also received a three-year New Investigator Fellowship from the Ontario Mental Health Foundation in 2010 to study people with developmental disabilities, who make up between one and three per cent of the Canadian population. At least one in three people with developmental disabilities will have mental health problems or serious challenging behaviours as an adolescent or young adult, says Weiss.

His goal for this project is to learn what leads a young person with developmental disability to have mental health problems, and how it is related to their service use, their skills, academic success and family functioning.
