Infant Temperament, Maternal Personality, and Parenting Stress as Contributors to Infant Developmental Outcomes
Open accessAbstract
This study examined contributions of maternal personality and infant temperament to infant vocabulary and cognitive development both directly and indirectly through parental stress. Participants were recruited at birth and included 63 infant twin pairs and their mothers. Assessments were completed at 6, 9, 12, and 18 months of age and included Dimensions of Temperament–Revised (maternal personality), Parenting Stress Index (parental stress), Infant Behavior Questionnaire–Revised (infant temperament), Bayley Scales of Infant Development II: Mental Development Index, and MacArthur-Bates Total Vocabulary. Structural equation modeling with a jackknife approach was used to analyze data separately for each twin in the pair. At 12 months, maternal personality and infant temperament contributed indirectly to MacArthur-Bates Total Vocabulary and Bayley Mental Development Index scores through parental stress. In addition, infant temperament directly contributed to 12-month MacArthur-Bates Total Vocabulary. At 18 months, these relationships were no longer significant. The different findings at 12 months compared to 18 months may reflect important developmental and environmental shifts, as well as possible differences in the method and measurements used at each age.

Psychosocial stress in parents, including depressive or anxious symptoms, is associated with infant developmental delay and poor nutritional outcomes.
“Psychosocial stress in parents, including depressive or anxious symptoms, is also associated with infant developmental delay [5] and poor nutritional outcomes [8].”
From Material Hardship and Stress from COVID-19 in Immigrant Chinese American Families with Infants (2022) · cites this paper as [5]
The Summary of Results reports that greater maternal stress was linked to lower infant cognitive scores at 12 months, supporting the developmental-outcome portion of the claim. The paper does not establish that depressive or anxious symptoms specifically are associated with infant developmental delay. The nutritional-outcome portion is attributed to citation [8], not this source. (LLM, conf=0.85)
Experimental — accuracy not yet measuredMaterial hardships are associated with poor outcomes in key infant domains such as cognitive development, obesogenic feeding behaviors, and decreased sleep duration.
“Previous studies have identified associations between material hardships, or a lack of essential resources, and poor outcomes in key infant domains such as cognitive development [5], obesogenic feeding behaviors [6], and decreased sleep duration [7].”
From Material Hardship and Stress from COVID-19 in Immigrant Chinese American Families with Infants (2022) · cites this paper as [5]
Citation [5] is attached to cognitive development, not the feeding or sleep outcomes. The Discussion reports an association between maternal parenting stress and lower infant cognitive scores at 12 months, but neither it nor the passages found by searching for material hardship, poverty, and resource deprivation establish an association between lack of essential resources and infant cognitive development. (LLM, conf=0.76)

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.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
