Intentions : «The aim of the current study was to better understand the link between parenting stressors, sleep quality, and negative mood using a daily diary design.» (p. 298)
Questions/Hypothèses : «We hypothesized that on a between-person level, parenting stressors would interact with sleep quality to predict negative mood, such that the association between average levels of parenting stressors and mood would become stronger as average levels of sleep quality decreases. On a within-person level, we hypothesized that daily sleep quality would moderate the within-person association between daily parenting stressors and mood would be stronger on days with worst sleep quality than usual, compared to days with better sleep quality than usual.» (p.298)
Échantillon/Matériau : «Sixty-six participants were recruited via posters and meetings at schools and community groups for families of children with autism in a large metropolitan city. Participants were the biological of legal parents cohabiting with a child with a ASD [autism spectrum disorder] diagnosis. [They] completed daily diaries for six consecutive days at approximately the same time each evening. The daily diaries included measures of parenting stressors, negative mood, and sleep quality and quantity.» (p. 298) La ville d’origine des participants n’est pas mentionnée dans l’article.

«Results from the current study […] highlight the impact of sleep quality on mood in the context of chronic caregiving stress. Indeed, parents of children with ASD experience a number of sleep disturbances that are associated with daytime parenting stressors and that contribute to poor psychological [well-being. Further,] participants who reported on average more parenting stressors experienced greater mood reactivity following daily changes in sleep satisfaction, suggesting that the effects of transient sleep disturbances on mood may be more pronounced within the context of elevated chronic stress.» (p. 302) These findings «suggest that poor sleep quality is associated with greater negative mood among those with high levels of parenting stressors. Conversely, high levels of parenting stressors were associated with larger increases in negative mood following a night of poor sleep. Taken together, these results provide further evidence that sleep quality is a key resource facilitating adjustment to chronic stress.» (p. 303)
