The impacts of social buffering on parents’ self-reported and cardiac responsivity to a remote stress induction
Bibliographic record
Abstract
Elevated and chronic levels of parenting stress in the early years of a child’s life can have detrimental effects on social, cognitive, and emotional developmental outcomes. Canadian parents of young children reported significant elevations in stress levels during the COVID-19 pandemic, which highlighted a need to identify reliable methods of inducing and buffering stress remotely in this population. The primary objectives of the present study were (1) to assess whether a novel, internet-delivered version of the TSST (iTSST) could induce acute psychosocial stress in a sample of parents, and (2) to examine the impact of social buffering on parents’ perceived and biological reactivity following exposure to the iTSST. Self-identified parents (N = 60; n = 16, control; n = 24, stressor only; n = 20, stressor plus social buffering; 60.0% non-White) of children under 48 months old completed a 1 hr Zoom assessment during which the iTSST/placebo protocol was administered. Self-reports of stress and anxiety, along with smartphone measures of photoplethysmography, were collected throughout the assessment to assess reactivity to, and recovery from, the iTSST. Findings revealed that parents who completed the iTSST exhibited significant elevations in stress and anxiety as compared to pre-iTSST levels and parents who completed the placebo procedures. No evidence of reactivity effects on heart rate were observed. Additionally, no evidence of a significant buffering effect emerged; however, it was notable that parents who interacted with a friend, romantic partner, or family member post-iTSST showed a non-significant trend of lower self-reported stress and anxiety relative to parents who engaged in an article reading period post-iTSST. Results of the present study further validate the efficacy of the iTSST in eliciting significant self-reported reactivity in a sample of exclusively parents. Implications and considerations for future studies involving remote stress induction and buffering in parents and racially diverse samples are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
