Remember when Mom used to roll out that chart of y'all's chores for the week, and you used to moan and groan about it? Well, there's scientific proof that she was doing you ingrates a favor, even if it did come 20 years too late.
For example, three doctors [1] from the University of Virginia Children's Hospital (Go Hoos!) analyzed data from almost 10,000 children entering kindergarten in 2010 to 2011. The kids' parents reported how often their children did chores. When the kids were in the third grade, they responded to a questionnaire regarding their perceived interest or competence in academics, peer relationships, prosocial behavior, and life satisfaction. They also completed direct academic assessments for reading, math, and science. The doctors analyzed the data and found, among other things, that "[t]he frequency of chores in kindergarten was positively associated with a child's perception of social, academic, and life satisfaction competencies in the third grade, independent of sex, family income, and parent education," and that "[p]erforming chores with any frequency in kindergarten was associated with improved math scores in the third grade." This led the UVA docs to conclude that "performing chores in early elementary school was associated with later development of self-competence, prosocial behavior, and self-efficacy."
