Abstract

Parents of children with autism spectrum disorders (ASDs) have higher rates of depressive symptoms than parents of typically developing (TD) children or parents of children with other developmental disorders. The purpose of this study was to examine child and parent sleep as factors associated with depressive symptoms in parents of children with ASDs. Participants included 34 families (17 ASD, 17 TD, 17 mothers and 11 fathers per group). Both objective sleep quantity (actigraphy) and subjective sleep quality were obtained, along with measures of parent depressive symptoms and child daytime behavior. Child sleep quantity was a significant predictor of maternal depressive symptoms, controlling for group and child behavior. Fathers sleep quality was a significant predictor of paternal depressive symptoms, controlling for child behavior and child sleep disturbances. This study suggests that along with child behavior, parent and child sleep variables are associated with parental depressive symptoms. Future studies should continue to use a multi-method measurement approach for sleep, and interventions that target child sleep should include parent sleep and parent daytime functioning as outcome variables.

Depressive symptoms in parents of children with autism spectrum disorders

Multiple studies have reported elevated levels of depressive symptoms and psychological distress in parents of children with autism spectrum disorders (ASDs). These differences have been found in parents of children with ASDs compared to parents of children with Down syndrome (Abbeduto et al., 2004, Piven et al., 1991), mental retardation (Weiss, 2002), fragile X syndrome (Abbeduto et al., 2004), developmental delay (Estes et al., 2009), as well as children who are typically developing (Hoffman

Sleep in children with ASDs and their parents

Sleep problems are common among children with autism spectrum disorders (ASDs), including prolonged sleep onset, frequent and/or prolonged night wakings (Honomichl et al., 2002, Patzold et al., 1998, Souders et al., 2009, Wiggs and Stores, 2004, Williams et al., 2004), and/or early morning sleep termination (Hering et al., 1999, Patzold et al., 1998, Wiggs and Stores, 2004). For families who have children with ASDs, parent sleep may be disturbed due to the increased supervision required when a

A multi-method assessment approach for sleep

The most commonly used methods for assessing sleep are questionnaires and sleep diaries. Questionnaires provide a retrospective report on sleep quantity and quality, while sleep diaries ask participants to prospectively report on sleep quantity and quality. However, as mentioned, both types of measures can result in reporter bias when examining the relationship between sleep and another self-report measure such as depression. In the case of children, questionnaires and sleep diaries are also

Participants

Families of children with ASDs and families of TD children were included in the study if they had a child ages 4–10 years (inclusive). Children with an ASD were required to have a documented diagnosis from a physician or psychologist, as well as a score of >15 (cutoff point for children likely to have autism) on the Social Communication Questionnaire (SCQ) (Rutter, Bailey, & Lord, 2003), a well-validated parent-report screener for autism symptoms. Children in the TD group were required to have

Preliminary analyses

No significant differences were found between groups for any of the demographic variables (Table 1). A statistically significant difference between children with ASDs and TD children was not found for sleep quantity. However, children with ASDs slept 30 min less than TD children. One-way ANOVAs found significant difference in depressive symptoms for mothers, but not fathers, suggesting that mothers of children with ASDs report more depressive symptoms than mothers of TD children (Table 2).

Discussion

This study is one of the first to utilize a multi-method approach to examine the relationship between child sleep, parent sleep, and parent depressive symptoms. As expected, after controlling for child behavior, sleep variables provided an additional factor that may contribute to increased depression in parents of children with ASDs. Although the generalizability of the study findings are limited by the small sample size, there were several strengths of this exploratory study, including the

      McDaniel and Teti [62] and Cook et al. [56] reported a positive association between infant sleep disruption and depressive symptoms amongst fathers. However, four of the six identified studies of infant [55,65] and child [40,45] sleep problems showed no significant association with depressive symptoms. Additionally, both Countermine and Teti [57] and Kenny et al. [59] reported that infant sleep location was not significantly associated with depressive symptoms.

      Approximately half of two- to five-year old children with developmental disorders, including autism spectrum disorder (ASD), have sleep disturbances, such as sleep onset problems and night wakings, compared to nearly one-third of typically developing children (Krakowiak, Goodlin-Jones, Hertz‐Picciotto, Croen, & Hansen, 2008). Shorter total sleep time among school-age children with developmental disabilities has been associated with increased parental depressive symptoms (Meltzer, 2011). Greater overall sleep disturbances in school-age children with ASD is associated with more maternal mental health problems including symptoms of somatization, obsessive-compulsive disorder, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism (Hodge, Hoffman, Sweeney, & Riggs, 2013).
