Psychometric evaluation of the Parental Reflective Functioning Questionnaire in Polish mothers.

Parental reflective functioning (PRF) refers to a parent's capacity to reflect on and understand the inner mental states of their child, their own mental states with regard to their child, and how these mental states may influence their behavior and interactions. This capacity has been shown to foster secure attachment in children and their socio-emotional development. The present study examined the psychometric properties of the Polish translation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief screening measure of PRF, in a large community sample of Polish mothers of children aged 0-5 years (N = 979). Confirmatory factor analysis supported the hypothesized three-factor structure of the PRFQ, which consists of three subscales: prementalizing modes, certainty about mental states, and interest and curiosity in mental states. However, item loadings suggested that the 15-item version fitted the data better than the original 18-item version. These three PRFQ subscales exhibited satisfactory and moderate six-month test-retest reliability. They also correlated in theoretically expected ways with several criterion measures such as maternal attachment, maternal parenting stress, parental role restriction, depression severity, and borderline symptoms. In conclusion, this study is the first to provide preliminary evidence for the reliability and validity of the PRFQ as a measure of parental reflective functioning in Polish mothers.

Attachment security, verbal ability, and inhibitory control in middle childhood.

BACKGROUND: The relationship between parent-child attachment and executive function (EF) in middle childhood remains relatively poorly studied. Very little is known about the role that the child's verbal ability might play in these relationships. Therefore, in the present study, we explored the concurrent links between perceived attachment security with parents and hot and cool inhibitory control (IC)-a core component of EF-as well as the potential mediating role of verbal ability in those links. METHODS: The participants were 160 children aged 8 to 12 (51% girls). They completed the Attachment Security Scale, the computerised version of the go/no-go task, the delay discounting task, and the vocabulary subtest from the Wechsler Intelligence Scale for Children. Pearson's correlations were conducted to test relationships between the study variables. A hierarchical multiple linear regression analysis was performed to examine whether attachment security uniquely contributed to the outcomes after accounting for covariates. The indirect effects were tested using a non-parametric resampling bootstrap approach. RESULTS: The results showed that, after accounting for the child's age and sex, there was a direct relationship between attachment security with the father and cool, but not hot, IC. However, there were no significant links between attachment security with the mother and both aspects of IC. We also found that children's verbal ability played a mediating role in the associations between both child-father and child-mother attachment security and hot, but not cool, IC above and beyond the child's age. CONCLUSIONS: The current study extends previous work on executive functions in middle childhood. The results highlight the role of attachment in explaining individual differences in IC in middle childhood as well as the different mechanisms through which attachment with parents might explain cool vs. hot IC. The findings have potential implications for therapeutic interventions using the family context as a target to improve IC in middle childhood.

Attachment to mothers and fathers during middle childhood: an evidence from Polish sample.

BACKGROUND: Middle childhood is a significant period of change both for a child's cognition and social functioning. Considering that the primary developmental theme of attachment in middle childhood is the balance between child's growing autonomy and the constant need of relatedness, cultural differences in developmental trends in the attachment might be considered as a function of individualism and collectivism orientations. However, little is known about whether the findings on predictors of individual differences in the attachment in middle childhood found in Western cultures, hold within the non-Western ones. Moreover, still little is known about differences between attachment to mothers and fathers in middle childhood. Hence, one goal of the present study was to investigate the role of a child's age, sex, and emotionality in a middle-childhood attachment to mothers and fathers in the Polish sample. The second aim was to compare obtained results to the attachment research that focused on Western cultures. METHODS: The sample consisted of 132 children aged 8-12 years (51% boys). They completed the Kern's Security Scale and the Coping Strategies Questionnaire. Mothers completed a child's EAS-C and short sociodemographic questionnaire. Pearson's correlations were conducted to test relationships between a child's age, sex, emotionality, SES, and attachment-related variables. A paired-samples t-test was used to compare the intensity of preoccupied and avoidant coping strategies with parents in the whole sample. The effects of a child's age, sex, temperament, and attachment figure were tested with separate repeated-measures ANOVA. RESULTS: Some of the results replicated prior studies conducted in Western cultures. Similarly to the individualistic cultures, older Polish children reported less preoccupied and more avoidant coping strategies with their parents than younger children. Second, older girls reported higher felt-security with their fathers than with mothers, which suggests some significant changes in attachment relationships regarding the child's sex. However, as opposed to Western cultures, there were no links between the child's sex and preoccupied and avoidant coping. Polish children also reported higher rates of preoccupied coping than the avoidant one. Finally, children with relatively lower emotionality reported higher attachment security with both parents than children with relatively higher emotionality. CONCLUSIONS: The current study extends previous work on attachment in middle childhood, the area of rather sparse research, as compared to other developmental periods. The findings reveal the existence of both some specificity in the middle-child attachment in the Polish sample, as well as some culture-universal developmental trends. However, as many questions remain unanswered, they also highlight the strong need for future cross-cultural and comparative studies.

Can sustained attention adapt to prior cognitive effort? An evidence from experimental study.

According to the limited resources paradigm, prior cognitive effort should result in a temporary depletion of available cognitive resources (Kahneman, 1973). Some recent evidence however has proved an opposite effect of increment in the availability of cognitive resources as a function of prior cognitive effort. In the current study the follow-up effect of cognitive effort on sustained attention was examined. Eighty-nine participants took part in the experiment. The cognitive load was manipulated between subjects using three versions of the DIVA Task (intensive warming-up condition, moderate warming-up condition and the control one). Following the experimental manipulation, the availability of cognitive resources during vigilance task was checked. Some significant effects of experimental manipulation were observed. First, in the context of overall task performance, subjects from the intensive warming-up condition obtained lower total errors rate than subjects from the control one. Some moderate effect of cognitive warming-up on time-on-task performance was also observed, although it was isolated to false alarms rate. Those results, tentatively suggesting the occurrence of the cognitive warming-up effect in vigilance performance, are then discussed.
