Аннотация:Executive functions (EFs) in preschool age are significant predictors ofcognitive development with long-term effects in adulthood; they are influenced by severalfactors, including personality traits and socioeconomic status. Recent studies highlight thesignificant parental influence, especially as parent-reported questionnaires have gainedimportance in assessing children’s EFs. The aim of this study was to examine the role of parentalpersonality traits and parenting behaviors in assessing the development of EFs in preschoolchildren. The study involved 526 mothers of preschoolers (aged 24–55, M = 36.74, SD = 4.91).The participants completed a survey based on Russian-language versions of the ChildhoodExecutive Functioning Inventory (CHEXI), the Ten-Item Personality Inventory (TIPI-RU) andan item-reduced version of the Comprehensive General Parenting Questionnaire (CGPQ). Thestudy revealed significant associations of parental personality traits and parenting behaviorswith assessments of children’s EFs. The parents who rated their children’s EFs more positivelydemonstrated higher levels of extraversion, conscientiousness and openness, as well as structuredand caring parenting, while negative ratings correlated with neuroticism and controllingbehaviors. Structured parenting showed a positive association with conscientiousness, extraversion,agreeableness, and openness to experience, but a negative correlation with neuroticism.Caring parenting similarly correlated with conscientiousness and extraversion, while controllingbehaviors showed minimal associations with personality traits. These findings highlight therelationship of parental perceptions with personality traits and behaviors, suggesting the need tocritically interpret parent-reported assessments of children’s EFs in clinical and educationalcontexts, emphasizing the value of integrating multiple assessment methods and developingimproved instruments that account for parental perception biases.
