Sisters Protect Siblings From Depression, Study Found.

Study Finds That Sisters Protect Siblings From Depression

Something about having a sister, even a little sister, makes 10 to 14-year-olds a bit less likely to feel depressed.

A study of nearly 400 families has shown that having a sister helps to protect young teens from feeling lonely, unloved, guilty, self-conscious and fearful. Researchers studied 395 families from Seattle with two or more children. At least one child in each family was between the ages of 10 and 14. The research discovered that affectionate siblings have positive influences on each other regardless of age, gender, or how many years they are apart:

That’s one of several intriguing findings from a new study on the impact siblings have on one another. Brigham Young University professor Laura Padilla-Walker is the lead author on the research, which also sorts out the influence of siblings and the influence of parents within families.

“Even after you account for parents’ influence, siblings do matter in unique ways,” said Padilla-Walker, who teaches in BYU’s School of Family Life. “They give kids something that parents don’t.”

Padilla-Walker’s research stems from BYU’s Flourishing Families Project and appeared in the Journal of Family Psychology. The study included 395 families with more than one child, at least one of whom was an adolescent between 10 and 14 years old. The researchers gathered a wealth of information about each family’s dynamic, and followed up again one year later to collect more data. Statistical analyses showed that having a sister protected adolescents from feeling lonely, unloved, guilty, self-conscious and fearful. These wonderful effects were seen in siblings having older sisters and also in those having younger sisters, and they occurred regardless of the age differences.

Brothers mattered, too. The study found that having a loving sibling of either gender promoted good deeds, such as helping a neighbor or watching out for other kids at school. In fact, loving siblings fostered charitable attitudes more than loving parents did. The relationship between sibling affection and good deeds was twice as strong as that between parenting and good deeds.

“For parents of younger kids, the message is to encourage sibling affection,” said professor Padilla-Walker. “Once they get to adolescence, it’s going to be a big protective factor.”

Many parents justifiably worry about the seemingly endless fighting between siblings. The study found hostility was indeed associated with greater risk of delinquency. Yet Padilla-Walker also sees a silver lining in the data: The fights give children a chance to learn how to make up and to regain control of their emotions, skills that come in handy down the road.

“An absence of affection seems to be a bigger problem than high levels of conflict,” Padilla-Walker explains.

Let your sister know how grateful you are to have her in your life, as you both likely helped protect each other from the many symptoms of depression by being there for one another.

You are Loved.
