URBANA, Ill. – Research has shown that consistently not getting enough sleep, or getting poor quality sleep, can put you at risk for a number of health conditions. But how does sleep, or the lack of it, affect how you parent?

A new study from Kelly Tu, a human development and family studies researcher at the University of Illinois, and colleagues, looks at the link between maternal sleep and permissive parenting during late adolescence. Findings show that mothers who don’t get enough sleep or who take longer falling asleep have a greater tendency to engage in permissive parenting—parenting marked by lax or inconsistent discipline.

Results also show that sleep quality may be especially important for African-American mothers and mothers from socioeconomically disadvantaged households.

“Short and disrupted sleep patterns are common among parents, especially parents of young children, and can affect their mental and physical health and daily functioning,” explains Tu, assistant professor in the Department of Human Development and Family Studies at U of I. “Extending this work beyond young children, we were curious as to how sleep affects the parenting of adolescents.”

During adolescence—11 to 18 years of age—parental involvement is still an important contributing factor in how well kids are adjusting socially, emotionally, and behaviorally. Tu explains that research has shown a link between permissive parenting and adolescents’ vulnerability to problematic or risky behaviors.

Those risky behaviors during adolescence could include affiliating with deviant or delinquent peers, engaging in delinquent behavior (vandalism or skipping school), or substance use and abuse, Tu explains. “Given that permissive parenting may heighten the risk of adolescents’ risky behaviors, we wanted to take a step back to ask what’s driving these permissive parenting behaviors, and to see if sleep could be a contributing factor.

“We found that when mothers were not receiving enough sleep, or receiving poor quality sleep, it had an effect on their levels of permissiveness with their adolescents. It may be that they’re more irritable, experiencing impaired attention, or so over-tired that they are less consistent in their parenting. But on the plus side, we also find that mothers who are receiving adequate sleep are less likely to be permissive with their adolescents.”

To examine maternal sleep duration and quality, 234 mothers were asked to wear actigraphs—a wristwatch-like device, think of a Fitbit—at bedtime for seven consecutive nights. The actigraph detects movement throughout the night and determines whether there is a disruption in sleep. Information about race/ethnicity and socioeconomic status of the mothers was also collected.

Adolescents, averaging 15 years of age, then completed questionnaires (subscales of the Parent Behavior Inventory) about how they perceived their mothers’ parenting. They rated behavior on a scale of “likely or not likely to.” Example statements included, “Lets me off easy when I do something wrong,” “Can’t say no to anything I want,” or “Doesn’t check up to see whether I have done what she told me.”

Findings showed that mothers who had longer durations of sleep or who were able to fall asleep easily, had adolescents who reported lower levels of permissive parenting.

Race/ethnicity and socioeconomic status also emerged as significant factors in linking sleep quality with permissive parenting. African-American mothers and mothers from lower socioeconomic households who experienced higher quality sleep (higher sleep efficiency, fewer night wakings) had lower levels of permissive parenting. Yet, for these same mothers, poorer sleep quality resulted in higher levels of permissive parenting.

“Studies have documented sleep disparities among ethnic minority and socioeconomically disadvantaged individuals, and our findings are consistent with that. For socioeconomic status, we may need to consider the day-to-day stressors or challenges that these mothers are facing,” Tu explains. “Mothers from lower socioeconomic households may be encountering additional stressors or financial hardships that could be affecting their sleep and/or parenting.

“But what’s exciting is that we also find positive effects of high quality sleep on parenting behaviors for ethnic minority and socioeconomically disadvantaged mothers,” Tu says.

The findings from the study, Tu says, point out the need for self-care and the importance of sleep.

“Sleep is an easier point to intervene in terms of changes individuals can make—things like not drinking caffeine or exercising too close to bedtime, establishing a bedtime routine, and thinking about the sleep environment,” she says. “Parents may be thinking about these things when it comes to their children, but it’s just as important for parents to get enough sleep as it may impact their family interactions and children’s well-being.”
