Positive Parenting and Early Childhood Cognition: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Effectiveness of Learning through Play Plus (LTP Plus) Parenting Intervention on Behaviours of Young Children of Depressed Mothers: A Randomised Controlled Trial

Evidence has shown that parenting intervention programmes improve parental knowledge, attitudes, and practices, which helps in promoting child development. This study aims to examine the effectiveness of parenting intervention in improving child behaviours. This is a secondary analysis of data from a cluster-randomised controlled trial with depressed mothers aged 18-44 years with a child aged 0 to 36 months. This paper reports findings from the dataset of participants with a child aged between 24 and 36 months. Villages (n = 120) were randomised into either of two arms: learning through play plus (LTP Plus) or treatment as usual (TAU). LTP Plus is a 10-session, group parenting intervention integrated with cognitive behaviour therapy, delivered over 3 months. This secondary analysis reports findings on the Eyberg Child Behaviour Inventory (ECBI) and the Home Observation for Measurement of the Environment (HOME). Findings show a significant improvement in child behaviour (ECBI) scores (p < 0.011) and HOME scores (p < 0.001) in the intervention group compared to TAU at 3-month follow-up. In a low-resource setting, low-cost group parenting intervention delivered by community health workers has the potential to improve child behaviours and quality of the home environment. Parenting interventions aimed at improving child behavioural problems can have significant implications for the child, family, and broader societal outcomes. Addressing behavioural problems in early years, parenting interventions can potentially reduce long-term consequences and costs associated with untreated child behavioural issues.

Maternal asthma symptoms during pregnancy on child behaviour and executive function: A Bayesian phenomics approach

OBJECTIVE

Maternal history of inflammatory conditions has been linked to offspring developmental and behavioural outcomes. This phenomenon may be explained by the maternal immune activation (MIA) hypothesis, which posits that dysregulation of the gestational immune environment affects foetal neurodevelopment. The timing of inflammation is critical. We aimed to understand maternal asthma symptoms during pregnancy, in contrast with paternal asthma symptoms during the same period, on child behaviour problems and executive function in a population-based cohort.

METHODS

Data were obtained from 844 families from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort. Parent asthma symptoms during the prenatal period were reported. Asthma symptoms in children were reported longitudinally from two to five years old, while behavioural problems and executive functioning were obtained at seven years old. Parent and child measures were compared between mothers with and without prenatal asthma symptoms. Generalized linear and Bayesian phenomics models were used to determine the relation between parent or child asthma symptoms and child outcomes.

RESULTS

Children of mothers with prenatal asthma symptoms had greater behavioural and executive problems than controls (Cohen's d: 0.43-0.75; all p < 0.05). This association remained after adjustments for emerging asthma symptoms during the preschool years and fathers' asthma symptoms during the prenatal period. After adjusting for dependence between child outcomes, the Bayesian phenomics model showed that maternal prenatal asthma symptoms were associated with child internalising symptoms and higher-order executive function, while child asthma symptoms were associated with executive function skills. Paternal asthma symptoms during the prenatal period were not associated with child outcomes.

CONCLUSIONS

Associations between child outcomes and maternal but not paternal asthma symptoms during the prenatal period suggests a role for MIA. These findings need to be validated in larger samples, and further research may identify behavioural and cognitive profiles of children with exposure to MIA.

Observations of Positive Parenting from Online Parent-Child Interactions at Age 1

Objective

Brief, reliable, and cost-effective methods to assess parenting are critical for advancing parenting research.

Design

We adapted the Three Bags task and Parent Child Interaction Rating System (PCIRS) for rating online visits with 219 parent-child dyads (White, n = 104 [47.5%], Black, n = 115 [52.5%]) and combined the video data with survey data collected during pregnancy and when children were aged 1.

Results

The PCIRS codes of positive regard, stimulation of child cognitive development, and sensitivity showed high reliability across the three parent-child interaction tasks. A latent positive parenting factor combining ratings across codes and tasks showed good model fit, which was similar regardless of parent self-identified race or ethnicity, age, socioeconomic disadvantage, marital/partnered status, and parity, as well as methodological factors relevant to the online video assessment method (e.g., phone vs. laptop/tablet). In support of construct validity, observed positive parenting was related to parent-reported positive parenting and child socioemotional development. Finally, parent reports of supportive relationships in pregnancy, but not neighborhood safety or pandemic worries, were prospectively related to higher positive parenting observed at age 1. With the exception of older parental age and married/partnered status, no other parent, child, sociodemographic, or methodological variables were related to higher overall video exclusions across tasks.

Conclusions

PCIRS may provide a reliable approach to rate positive parenting at age 1, providing future avenues for developing more ecologically valid assessments and implementing interventions through online encounters that may be more acceptable, accessible, or preferred among parents of young children.

The gradients of the relationship between child discipline practices at home and early childhood development of young children

BACKGROUND

Although the literature suggests a negative association between early childhood development (ECD) and violent disciplinary measures, little is known about the gradient of this relationship.

OBJECTIVE

This study examined the gradient of the relationship between the number and types of child discipline practices at home and the ECD of children aged from 36-to-59 months.

PARTICIPANTS AND SETTING

The study used nationally representative data from the Multiple Indicator Cluster Survey Bangladesh 2019.

METHODS

We analysed secondary data using multivariable logistic regression to examine the relationship between child discipline practices and ECD. The gradients were measured using three sets of summative indexes of disciplinary practices and psychometric approach to the physical, literacy-numeracy, learning and social-emotional domains of ECD.

RESULTS

About 94 % of children had at least one of the eight violent disciplinary measures during the month preceding the survey. Approximately three-quarters of the children were on track in their ECD. The probability that children were on track in ECD significantly increased with non-violent disciplinary practices and decreased with violent disciplinary practices used. For one unit increase in the overall violent disciplinary index, the odds of children being on track in their ECD was reduced by 12 %, and the reduction was significant (adjusted odds ratio = 0.88; 95%CI: 0.86-0.91).

CONCLUSIONS

Children who had experienced several forms of violent disciplinary measures were more likely than those who did not to be delayed in their ECD. Banning violent punishments in all settings and positive parenting programs are recommended.

Literature landscape of neurodevelopment and pesticides: A scoping review of methodologies

Pesticides are highly tested and regulated chemicals. There is currently great interest in the role that pesticides may play in childhood neurodevelopment. The objective was to identify and describe the body of evidence and to assess the ability to synthesize effect estimates. The epidemiologic literature from 2011 to 2022 was searched for publications on the association between pesticide exposure and neurodevelopment, behavior, and/or cognition in children. We identified 114 publications, representing 67 unique studies. While organochlorine and other insecticides were the most common classes of pesticides studied, up to 159 different metabolites or active ingredients were reported. Nine pesticides or their metabolites were reported in >10 publications. Similarly, multiple assessment methods were administered across studies to evaluate outcomes in neurodevelopment at ages which ranged from birth to 18 years of age. This scoping review reveals the heterogeneity among published studies with respect to exposures and health outcomes, in the methods used to assess and classify them, and in combinations of the two. This limits the adequacy of the evidence to evaluate specific risk estimates for a particular exposure-outcome pair. Intentional coordination among researchers to increase consistency in methodologies would facilitate the synthesis of results across studies. Research opportunities also exist to validate assumptions in exposure and outcome assessment which are implicit in many of the studies reviewed. In conclusion, there are many ongoing epidemiologic studies with a focus on pesticides and neurodevelopment. The variety of exposures, exposure assessment methods and tests for each outcome can be overwhelming. Interdisciplinary collaboration is recommended to harmonize data collection and to enable meaningful interpretation of the study results across populations.

Commentary: Cognitive stimulation and executive functions in the prevention and treatment of childhood disorders - reflection on Phillips et al., 2023

The study by Phillips et al. (Journal of Child Psychology and Psychiatry, 2023) shows that preschool executive functions (EF) are a transdiagnostic mechanism through which deprivation increases the risk for psychopathology in adolescence. In addition, deprivation appeared to be a key mechanism through which economic adversity (i.e., lower income-to-needs ratio and maternal education) undermines EF and increases the risk for psychopathology in adolescence. In this commentary, implications for early prevention and treatment of childhood disorders are discussed. In view of optimal EF development attention is needed to cognitive and social stimulation both in: (a) selective prevention targeting preschool children at high risk for childhood disorders due to low socioeconomic status; (b) indicated prevention targeting preschool children with minimal but detectable symptoms from low socioeconomic status families; and (c) treatment targeting preschool children with a clinical disorder from low socioeconomic status families.
