Cardiac vagal control and children's adaptive functioning: A meta-analysis

Open access
Graziano, Paulo, Derefinko, Karen·2013·Biological Psychology

Abstract

Polyvagal theory has influenced research on the role of cardiac vagal control, indexed by respiratory sinus arrhythmia withdrawal (RSA-W) during challenging states, in children’s self-regulation. However, it remains unclear how well RSA-W predicts adaptive functioning (AF) outcomes and whether certain caveats of measuring RSA (e.g., respiration) significantly impact these associations. A meta-analysis of 44 studies (n = 4,996 children) revealed small effect sizes such that greater levels of RSA-W were related to fewer externalizing, internalizing, and cognitive/academic problems. In contrast, RSA-W was differentially related to children’s social problems according to sample type (community vs. clinical/at-risk). The relations between RSA-W and children’s AF outcomes were stronger among studies that co-varied baseline RSA and in Caucasian children (no effect was found for respiration). Children from clinical/at-risk samples displayed lower levels of baseline RSA and RSA-W compared to children from community samples. Theoretical/practical implications for the study of cardiac vagal control are discussed.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Social-effect confidence interval contradicts its estimate and significance label

    Major

    The reported social-effect estimate is positive, but its entire confidence interval is negative. That interval also excludes zero, contrary to the result being labeled non-significant.

  • Discussion overstates the RSA-withdrawal group difference

    Major

    The discussion calls the clinical-versus-community difference in RSA withdrawal significant, whereas the results call it marginal and give p = .058.

  • A result is called significant despite the stated alpha threshold

    Minor

    The methods set the minimum alpha level at .01, but the baseline-RSA analysis is described as significant with p = .02.

  • File-drawer claim treats an already non-significant social result as significant

    Minor

    The file-drawer section says additional studies would be needed to make the social result non-significant, but the primary analysis already reports that result as non-significant.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
