Prediction of 7-year psychopathology from mother-infant joint attention behaviours: a nested case-control study

Association of self-reported mother-infant relationship with child and adolescent mental health

BACKGROUND

The quality of the relationship between mother and infant may have profound implications for the development of a child. Early indicators of psychological vulnerability may allow targeting of support for the child's cognitive, emotional and social development. A challenging mother-infant relationship could be one indicator of risk.

AIMS

This study examined variations in psychological well-being and psychopathology among boys and girls according to early maternal perception of the mother-infant relationship.

METHOD

This study is based on 64 663 mother-infant pairs from the Danish National Birth Cohort, for which data on the mother-infant relationship were collected at 6 months postpartum. Behavioural problems were assessed with the Danish version of the Strengths and Difficulties Questionnaire (SDQ) at child ages 7, 11 and 18 years, and we retrieved information on diagnosed childhood and adolescent psychiatric disorders and prescriptions of psychotropic drugs from Danish registries.

RESULTS

Children in the challenging mother-infant relationship group had higher odds of behavioural problems at age 7 among both boys and girls. The same pattern of elevated estimates was identified for boys across all SDQ domains and for girls in three of five SDQ domains. All associations were attenuated at age 18, but increased odds of behavioural problems still existed. A challenging early mother-infant relationship increased the offspring's risk of being diagnosed with a psychiatric disorder or being prescribed a psychotropic drug before the age of 18.

CONCLUSION

A challenging self-reported mother-infant relationship was associated with later psychopathological difficulties. Routine clinical enquiry may be useful in identification of future vulnerability.

Family wellbeing in general practice: a study protocol for a cluster-randomised trial of the web-based resilience programme on early child development

BACKGROUND

Social, emotional and behavioural problems in early childhood are associated with increased risk for a wide range of poor outcomes associated with substantial cost and impact on society as a whole. Some of these problems are rooted in the early mother-infant relationship and might be prevented. In Denmark, primary health care has a central role in preventive care during pregnancy and the first years of the child's life and general practice provides opportunities to promote a healthy mother-infant relationship in early parenthood.

OBJECTIVE

In the context of standardised antenatal and child development assessments focused on psychosocial wellbeing, we examine the impact of a complex intervention designed to improve maternal mentalisation skills, involving training of general practice clinicians and signposting towards a web-based resource. Joint main outcomes are child socio-emotional and language development at age 30 months measured by parentally reported questionnaires (Communicative Development Inventory and Strengths and Difficulties Questionnaire).

METHODS

The study is a cluster-randomised controlled trial based in general practices in the Capital Region and the Zealand Region of Denmark. Seventy practices were included. Practices were randomised by a computer algorithm in a ratio of 1:1 to intervention or control groups. Each practice was asked to recruit up to 30 women consecutively at their first scheduled antenatal assessment. Clinicians in both groups received one day of training in preventive antenatal and child development consultations with added focus on parental psychosocial well-being, social support, and parent-child interaction. These preventive consultations delivered in both trial arms require enhanced data recording about psychosocial factors. In intervention clinics, clinicians were asked to signpost a web page at three scheduled antenatal consultations and at four scheduled consultations when the child is 5 weeks, 5 months, 1 and 2 years.

DISCUSSION

We hypothesise that the intervention will increase mothers' ability to be sensitive to their child's mental state to an extent that improves the child's language and mental state at 30 months of age measured by parent-reported questionnaires.

Parent-infant observation for prediction of later childhood psychopathology in community-based samples: A systematic review

BACKGROUND

Difficulties in parent-child interaction are easily observed and are a potential target for early intervention. This review aimed to assess the utility of current observational methods used to assess parent-child interactions-within the first year of life-and their ability to screen and identify children from low-risk samples most at risk of developing childhood psychopathology.

METHODS

Six bibliographic databases were searched, and reference lists screened. All peer reviewed papers studying the association between an independent observation of parent-child interaction and later childhood psychopathology in community-based samples were included. Included studies were those recruiting from population or community-based birth cohort data, which we define as 'low-risk'. Studies based on populations known to have a diagnosis of psychiatric illness or developmental disorder, or at high genetic or environmental risk of being diagnosed with such disorder, were excluded. Results were synthesised qualitatively due to high heterogeneity.

RESULTS

20,051 papers were identified, nine were included in this study. Childhood psychopathology was associated with fewer positive parent-infant interactions, lower parent vocalisation frequency and lower levels of adult speech and activity. Maternal sensitivity was inversely related to separation anxiety and oppositional defiant/conduct disorders were associated with lower shared look rates. Disruptive behaviour disorders were associated with higher frequency of child vocalisation.

CONCLUSION

Assessment of parent-child interactions, particularly the level of maternal activity, may be an early indicator of later childhood psychopathology in low-risk samples. Further longitudinal, population-based studies are required.

Systematic Review and Meta-analysis: The Science of Early-Life Precursors and Interventions for Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

To evaluate which early neurocognitive and behavioral precursors are associated with the development of attention-deficit/hyperactivity disorder (ADHD) and whether these are currently targeted in early interventions.

METHOD

We conducted 2 systematic reviews and meta-analyses of empirical studies to examine the following: (1) early-life (0-5 years) neurocognitive and behavioral precursors associated with familial likelihood for ADHD, an early ADHD diagnosis/elevated ADHD symptoms, and/or the presence of later-childhood ADHD; and (2) interventions delivered to children aged 0 to 5 years targeting the identified precursors or measuring these as outcomes. Standardized mean differences (Hedges' g) and pre-post-treatment change scores (SMD) were computed.

RESULTS

A total of 149 studies (165,095 participants) investigating 8 neurocognitive and behavioral domains met inclusion criteria for part 1. Multi-level random-effects meta-analyses on 136 studies revealed significant associations between ADHD and poorer cognitive (g = -0.46 [95% CIs: -0.59, -0.33]), motor (g = -0.35 [CIs: -0.48, -0.21]) and language (g = -0.43 [CIs: -0.66, -0.19]) development, social (g = 0.23 [CIs: 0.03, 0.43]) and emotional (g = 0.46 [CIs: 0.33, 0.58]) difficulties, early regulatory (g = 0.30 [CIs: 0.18, 0.43]) and sleep (g = 0.29 [CIs: 0.14, 0.44]) problems, sensory atypicalities (g = 0.52 [CIs: 0.16, 0.88]), elevated activity levels (g = 0.54 [CIs: 0.37, 0.72]), and executive function difficulties (g = 0.34 [CIs: 0.05, 0.64] to -0.87 [CIs: -1.35, -0.40]). A total of 32 trials (28 randomized, 4 nonrandomized, 3,848 participants) testing early interventions that targeted the identified precursors met inclusion criteria for part 2. Multi-level random-effects meta-analyses on 22 studies revealed significant intervention-related improvements in ADHD symptoms (SMD = 0.43 [CIs: 0.22, 0.64]) and working memory (SMD = 0.37 [CIs: 0.06, 0.69]).

CONCLUSION

Children aged 0 to 5 years with current or later-emerging ADHD are likely to experience difficulties in multiple neurocognitive/behavioral functions. Early interventions show some effectiveness in reducing ADHD symptoms, but their effects on neurocognitive/behavioral difficulties require further study.

Parental education, parent-child relations and diagnosed mental disorders in childhood: prospective child cohort study

BACKGROUND

Mental disorder in childhood is an important public health issue. We aimed to examine the prospective association between parental education at childbirth and diagnosed mental disorders in young children and explore whether this association was mediated or modified by parent-child relations in infancy.

METHODS

Prospective cohort study of all newborn was from 2002 to 2010 from 16 municipalities in the capital region of Copenhagen, Denmark, with follow-up until their 8th birthday, N = 40 762. Baseline data included information from national population registers and from health visitors' records at child aged 0 to 10 months. Outcome variable: any mental disorder diagnosed at hospital from age 11 months to 8 years.

RESULTS

Low parental education was predictive of diagnosed child mental disorder, adjusted odds ratio (AOR) = 1.83 (95% CI 1.49-2.23). Problematic parent-child relation at age 8-10 months was also predictive of mental disorder, AOR = 2.06 (1.57-2.70) but did not mediate the association between parental education and mental disorder. AOR for mental disorders was 3.24 (2.03-5.16 for the combination vocational training and problematic parent-child relation and 2.49 (1.42-4.38) for the combination primary school and problematic parent-child relation.

CONCLUSIONS

Low parental education and problematic parent-child relation were independent risk factors for diagnosed mental disorders in the age span of 11 months to 8 years.

Detecting joint attention events in mother-infant dyads: Sharing looks cannot be reliably identified by naïve third-party observers

Joint attention, or sharing attention with another individual about an object or event, is a critical behaviour that emerges in pre-linguistic infants and predicts later language abilities. Given its importance, it is perhaps surprising that there is no consensus on how to measure joint attention in prelinguistic infants. A rigorous definition proposed by Siposova & Carpenter (2019) requires the infant and partner to gaze alternate between an object and each other (coordination of attention) and exchange communicative signals (explicit acknowledgement of jointly sharing attention). However, Hobson and Hobson (2007) proposed that the quality of gaze between individuals is, in itself, a sufficient communicative signal that demonstrates sharing of attention. They proposed that observers can reliably distinguish “sharing”, “checking”, and “orienting” looks, but the empirical basis for this claim is limited as their study focussed on two raters examining looks from 11-year-old children. Here, we analysed categorisations made by 32 naïve raters of 60 infant looks to their mothers, to examine whether they could be reliably distinguished according to Hobson and Hobson’s definitions. Raters had overall low agreement and only in 3 out of 26 cases did a significant majority of the raters agree with the judgement of the mother who had received the look. For the looks that raters did agree on at above chance levels, look duration and the overall communication rate of the mother were identified as cues that raters may have relied upon. In our experiment, naïve third party observers could not reliably determine the type of look infants gave to their mothers, which indicates that subjective judgements of types of look should not be used to identify mutual awareness of sharing attention in infants. Instead, we advocate the use of objective behaviour measurement to infer that interactants know they are ‘jointly’ attending to an object or event, and believe this will be a crucial step in understanding the ontogenetic and evolutionary origins of joint attention.

Differences in Established Joint Attention in Hearing-Hearing and Hearing-Deaf Mother-Child Dyads: Associations With Social Competence, Settings, and Tasks

The authors examined relations among observed joint attention, maternal report of child's social competence, setting (home vs. laboratory), task (unstructured vs. semi-structured), and dyad type [hearing mother-hearing child (n = 55, M_age  = 25.8 months) vs. hearing mother-deaf child (n = 27, M_age  = 26.9 months)]. Hearing child dyads scored higher on joint attention during unstructured tasks, especially in their home environment. Hearing child dyads displayed similar joint attention to deaf toddler dyads when they engaged in a semi-structured task, but higher on these measures during unstructured free play. Unlike hearing children, joint attention was differentially related to social competence in deaf children, with relatively higher versus lower social competence depending on relatively high versus low observed joint attention, respectively.
