Subclaims¶

q3 i? In a path model with good fit, the indirect effects from sleep to cognitive flexibility via inhibitory control and via working memory were both significant, while the direct path from sleep to cognitive flexibility was not. → Chen Y 2021 q3 i? A comparative model freeing the sleep-to-flexibility path confirmed the direct path was not significant while both indirect effects remained significant. → Chen Y 2021 (2)

Evidence¶

Chen Y 2021¶

Chen Y, Wang Y, Wang S, Zhang M and Wu N. (2021). Self-Reported Sleep and Executive Function in Early Primary School Children. Front. Psychol. 12:793000. https://doi.org/10.3389/fpsyg.2021.793000

q3 · i? · associational · r2

Path analysis computed with Mplus 7.0 using robust maximum likelihood in the same sample; model fit was reported as good (CFI = 0.996, RMSEA = 0.050). Both indirect effects were "significant"; the coefficients printed are unstandardised path coefficients, so no standardised effect size is reported.

"The indirect effects from sleep to cognitive flexibility via inhibitory control (coefficient = 0.130, SE = 0.032, t = 4.023, p < 0.001) and via working memory (coefficient = 0.125, SE = 0.035, t = 3.607, p < 0.001) w ere both significant."

q3 · i? · associational · r2

A comparative model freeing the sleep-to-flexibility path confirmed the direct path "was not significant" while indirect effects remained significant (ps < 0.001). Non-significance of the direct path does not establish independence.

"Results showed that the direct path from sleep to cognitive flexibility was not significant ( b = 0.090, SE = 0.171, t = 1.272, p = 0.203) and the indirect effects from sleep disturbance to cognitive flexibility via inhibitory control and via working memory remained significant (p s < 0.001)."
