When Kathryn Kerns asked 30 teens and preteens to come to her laboratory and talk about their parents, many of their dads scored low on a standard yardstick her research team was using to evaluate the parent-child bond.

The children described rich, warm relationships with their fathers, however, says Dr. Kerns, a professor of psychological sciences at Kent State University in Ohio. They said things like, “My dad gives me encouragement to do things,” or, “My dad tells me he thinks I can do well.”

To get an accurate assessment of fathers’ contribution, Dr. Kerns revised two assessments in her recently published study, adding questions about whether parents provided encouragement and instilled confidence, and the dads started drawing higher scores.

Dr. Kerns is one of a growing number of researchers creating new tests and techniques to document the father factor. More than a dozen studies in the past two years are yielding new insights into the nuances, and the value, of the seemingly random, sometimes silly play many dads engage in with their children.
