The development of Japanese mother–infant feeding interactions during the weaning period

During the weaning period, infants are not skilled at self-feeding and caregivers play a prominent role in feeding. Solid feeding is therefore an inherently collaborative and interactive process between infants and caregivers. The present study examined how caregivers and infants coordinate their solid feeding interactions, based on naturalistic longitudinal observations of three Japanese mother–infant dyads. The main results were as follows. Four or five months after weaning (about 10–11 months of age), children's mouth movements and mothers’ arm movements became more synchronized, and the success or failure of coordinated feeding became independent on children's gaze behavior. During this same period, both mothers’ and children's body movements accelerated. Specifically, children's food-intake motions and mothers’ food-carrying movements became faster together, although before 10–11 months fluctuations of these motions were not as correlated. Finally, at 9–11 months of age rhythmic body movements became frequent. From the first day of weaning, all three mothers swayed their bodies rhythmically while feeding, and about 2–3 months later their children also began to sway as they ate, at first infectiously but later spontaneously. These observations indicate how specific behavioral development contributes to mother–infant coordination in feeding.     

Mother–infant interaction improves with a developmental intervention for mother–preterm infant dyads

While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant‘s biological immaturity. This randomized clinical trial of 198 premature infants born at 29–34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention on mother–premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother–infant dyads were randomly assigned to the H-HOPE intervention group or an attention control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother–infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training–Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-min play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother–infant interaction (β = 2.03, p = 0.06) and significantly higher scores on the infant subscale (β = 0.75, p = 0.05) when compared to controls. In the adjusted analysis, H-HOPE dyads had increased odds of high versus low mutual responsiveness during play (OR = 2.37, 95% CI = 0.97, 5.80). Intervening with both mother and infant is a promising approach to help premature infants achieve the social interaction patterns essential for optimal development.     

Mutual touch during mother–infant face-to-face still-face interactions: Influences of interaction period and infant birth status

Contact behaviours such as touch, have been shown to be influential channels of nonverbal communication between mothers and infants. While existing research has examined the communicative roles of maternal or infant touch in isolation, mutual touch, whereby touching behaviours occur simultaneously between mothers and their infants, has yet to be examined. The present study was designed to investigate mutual touch during face-to-face interactions between mothers and their 5½-month-old fullterm (n = 40), very low birth weight/preterm (VLBW/preterm; n = 40) infants, and infants at psychosocial risk (n = 41). Objectives were to examine: (1) how the quantitative and qualitative aspects of touch employed by mothers and their infants varied across the normal periods of the still-face (SF) procedure, and (2) how these were associated with risk status. Mutual touch was systematically coded using the mother–infant touch scale. Interactions were found to largely consist of mutual touch and one-sided touch plus movement, highlighting that active touching is pervasive during mother–infant interactions. Consistent with the literature, while the SF period did not negatively affect the amount of mutual touch engaged in for mothers and their fullterm infants and mothers and their infants at psychosocial risk, it did for mothers and their VLBW/preterm infants. Together, results illuminate how both mothers and infants participate in shaping and co-regulating their interactions through the use of touch and underscore the contribution of examining the influence of birth status on mutual touch.     

Question–behaviour effect: A randomised controlled trial of asking intention in the interrogative or declarative form

Objective: This study investigated the question–behaviour effect of measuring intention in the interrogative or declarative form combined or not with a measure of moral norm.

Design: A sample of 762 participants was randomised according to a 2?×?2 factorial design.

Main outcome measures: Cognitions were assessed at the baseline, and physical activity behaviour was self-reported three weeks later. Results: At baseline, there were no significant differences on the studied variables. An ANOVA showed a significant interaction effect between the two experimental conditions (p?=?0.04). Post-hoc contrast analyses showed that the interrogative intention-only condition significantly differed from the declarative intention-only (d?=?0.21, p?=?0.03) and interrogative intention?+?moral norm (d?=?0.22, p?=?0.03) conditions.

Conclusion: Results suggest that self-posed questions about a future action increases the likelihood of doing it when these questions are not accompanied by measures of moral norm. This provides support for using introspective self-talk to favour the adoption of behaviour.     

Antenatal and postnatal depressive symptoms: Association with quality of mother–infant interaction

Antenatal and postnatal depression are independently associated with an increased risk of adverse infant development. A key linking mechanism is the quality of mother–infant interaction.ObjectivesThis study assesses the association between postnatal depressive symptoms (PDS) and their severity, with the quality of mother–infant interaction and compare the quality of mother–infant interaction and severity of the symptoms depending on the presence or absence of antenatal depressive symptoms (ADS).Methodsobservational study in 177 psychosocial risk mother–infant dyads from Chile (infant aged 2–12 months).ResultsMothers with PDS had lower maternal sensitivity and a more intrusive/controlling style than mothers without PDS, although the severity of the symptoms was not associated with lower maternal sensitivity. Maternal sensitivity did not differ in the postnatal depressed mothers depending on the presence of ADS, although the mothers differed in interaction style and the severity of symptoms. Mothers with ADS and PDS presented with a predominant intrusive/controlling interaction style and more severe depressive symptoms, whereas those with only PDS presented with a predominant nonresponsive/passive interaction style and reduced severity of symptoms.ConclusionsThe results corroborate the need to offer treatment and dyadic interventions to antenatal and postnatal depressive mothers and postulate that the presence of antenatal depressive symptoms may influence the subsequent mother–infant interaction style and greater severity of symptoms.     

Caregiving representations in war conditions: Associations with maternal trauma,mental health,and mother–infant interaction

Risk features in mothers’ caregiving representations remain understudied in dangerous environments where infants most urgently need protective parenting. This pilot study examines the feasibility of a novel coding system for the Parent Development Interview (PDI) interview (ARR, Assessment of Representational Risk) in assessing 50 war-exposed Palestinian mothers’ caregiving representations. First, we explored the content and structure of risks in the representations. Second, we examined associations between the high-risk representations, mothers’ pre- and postnatal exposure to traumatic war events (TWE), depressive and post-traumatic stress disorder (PTSD) symptoms, and self-rated emotional availability (EA) with their 1-year-old infants. Following three dimensions of high-risk caregiving representations were identified: self/dyadic dysregulation, unavailable, and fearful. Mothers’ prenatal depressive symptoms were associated with dysregulating and fearful representations, and their postnatal PTSD with fearful representations. TWE were not associated with the high-risk representations. Moreover, mothers of boys reported more fearful representations, and mothers with financial difficulties reported more unavailable representations. TWE and high-risk representations were not associated with EA. However, qualitative analysis of the representations indicated risks in the mother–infant relationship. Further, older mothers and mothers with postnatal PTSD reported lower EA. Cultural variance in caregiving representations and the use of self-report measures among traumatized mothers are discussed.     

Development of mother–infant interaction in tickling play: The relationship between infants’ ticklishness and social behaviors

This study examined the development of mother–infant tickling interaction and the relationship between infants’ ticklishness and social behaviors including infants’ looking at mothers’ face, mothers’ narrative tickling, and mothers’ laughter. Twenty-two Japanese infants aged 5 months (n = 10, five girls) and 7 months (n = 12, four girls) and their mothers were videotaped. Results revealed that the mothers’ narrative tickling was more frequent at 7 than at 5 months and the infants’ strong ticklishness showed the same tendency. The infants’ strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants’ ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother’s narrative tickling. A possible function of such mother’s narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed.     

Token transfer between mother and offspring chimpanzees (Pan troglodytes): mother–offspring interaction in a competitive situation

Chimpanzees can flexibly use tokens in cognitive tasks, but it is still unknown if they can share and/or compete over tokens as they do for food. This study aimed to evaluate the interactions spontaneously occurring between mother and offspring chimpanzees when tokens exchangeable for food were provided. Forty tokens were scattered on the floor in an experimental playroom. Three mother and offspring chimpanzee pairs were tested. Each token was exchangeable for a piece of food in a vending machine installed on the wall of the playroom. In the beginning of the study, both mother and offspring took tokens and exchanged them for pieces of food independently. Later, two offspring started to take more tokens than their mothers. At that time, the offspring whimpered or cried more often than during earlier sessions. This behavior compelled the mothers to abstain from taking tokens. The mothers sometimes shared their tokens with their offspring, or were tolerant of their offspring taking their tokens from their hand. For one pair, the offspring sometimes shared tokens with her mother when her mother begged for the tokens. These results suggest that chimpanzees’ cognitive abilities enable them not only to use tokens, but also to compete for tokens, as they do for food. The results also suggest that token sharing between mother and offspring may be bidirectional and that transfer of tokens mainly occurs as a result of begging, although on some occasion offspring were able to obtain a token directly from his/her mother through tolerated scrounging.     

Motherhood in adolescent mothers: Maternal attachment,mother–infant styles of interaction and emotion regulation at three months

Early motherhood is considered a risk factor for an adequate relationship between mother and infant and for the subsequent development of the infant. The principal aim of the study is to analyze micro-analytically the effect of motherhood in adolescence on the quality of mother–infant interaction and emotion regulation at three months, considering at the same time the effect of maternal attachment on these variables. Participants were 30 adolescent mother–infant dyads compared to 30 adult mother–infant dyads. At infant 3 months, mother–infant interaction was video-recorded and coded with a modified version of the Infant Caregiver Engagement Phases and the Adult Attachment Interview was administered to the mother. Analysis showed that adolescent mothers (vs. adult mothers) spent more time in negative engagement and their infants spent less time in positive engagement and more time in negative engagement. Adolescent mothers are also less involved in play with their infants than adult mothers. Adolescent mother–infant dyads (vs. adult mother–infant dyads) showed a greater duration of negative matches and spent less time in positive matches. Insecure adolescent mother–infant dyads (vs. insecure adult mother–infant dyads) demonstrated less involvement in play with objects and spent less time in positive matches. To sum up adolescent mother–infant dyads adopt styles of emotion regulation and interaction with objects which are less adequate than those of dyads with adult mothers. Insecure maternal attachment in dyads with adolescent mothers (vs. adult mother infant dyads) is more influential as risk factor.     

Increased skills usage statistically mediates symptom reduction in self-guided internet-delivered cognitive–behavioural therapy for depression and anxiety: a randomised controlled trial

Cognitive–behavioural therapy (CBT) is an effective treatment for clinical and subclinical symptoms of depression and general anxiety, and increases life satisfaction. Patients’ usage of CBT skills is a core aspect of treatment but there is insufficient empirical evidence suggesting that skills usage behaviours are a mechanism of clinical change. This study investigated if an internet-delivered CBT (iCBT) intervention increased the frequency of CBT skills usage behaviours and if this statistically mediated reductions in symptoms and increased life satisfaction. A two-group randomised controlled trial was conducted comparing internet-delivered CBT (n = 65) with a waitlist control group (n = 75). Participants were individuals experiencing clinically significant symptoms of depression or general anxiety. Mixed-linear models analyses revealed that the treatment group reported a significantly higher frequency of skills usage, lower symptoms, and higher life satisfaction by the end of treatment compared with the control group. Results from bootstrapping mediation analyses revealed that the increased skills usage behaviours statistically mediated symptom reductions and increased life satisfaction. Although skills usage and symptom outcomes were assessed concurrently, these findings support the notion that iCBT increases the frequency of skills usage behaviours and suggest that this may be an important mechanism of change.     

A randomised wait list-controlled pre–post–follow-up trial of a gratitude diary with a distressed sample

In a randomised wait list-controlled trial with repeated measures pre-, post- and follow-up design, participants (N = 109) with a current self-reported diagnosis of an anxiety disorder and/or depression, took part in an internet-based study. After completing a three-week gratitude diary returning participants had lower scores on measures of depression, anxiety, stress and perceived sleep difficulties and higher scores on a measure of subjective well-being than immediately pre-intervention. At three-week follow-up depression and sleep scores for returning participants were no longer significantly different from pre-intervention, however, improvements for subjective well-being and stress at post-intervention were maintained. At follow-up anxiety scores had not only been maintained but had improved significantly beyond post-intervention results. Intention to treat analyses were conducted and provided support for most completer results. Differences between the two sets of analyses are discussed below. This trial provides support for the use of gratitude diaries as an intervention with distressed populations.     

Maternal perinatal representations and their associations with mother–infant interaction and attachment: A longitudinal comparison of Portuguese and Brazilian dyads

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.     

The impact of exercise environments on adolescents’ cognitive and psychological outcomes: A randomised controlled trial

Exercise in natural environments can improve cognition, positive affect, and reduce psychological stress. However, it remains unclear whether these benefits are subject to a gradient effect, whereby more natural features confer greater cognitive and psychological benefits. This study examined the influence of the exercise environment (i.e., the degree of nature) on cognition, and psychological outcomes in a sample of adolescents (n = 90; mean age = 14.3 ±.05 years). Four groups were randomised to one of the following experimental conditions: a non-exercise indoor control, indoor exercise, park exercise, and exercise in a nature reserve. Participants’ self-reported their stress, affect, and vitality and completed two measures of cognition (‘Rapid Visual Information Processing’ and ‘Spatial Working Memory’) immediately before and ~6 min after exercise. All exercise conditions participated in a group-based circuit lasting ~20 min, which included a mixture of aerobic and body-weight resistance activities. Linear mixed models were used to examine changes within and between groups. The indoor group increased sustained attention accuracy compared to the park group. There were no between-group differences in working memory. The indoor and nature groups increased cognitive arousal compared to control. The park group improved in state-level vitality compared to control. The mixed-results of this research do not support our ‘nature gradient’ hypothesis, whereby cognitive and psychological outcomes would improve in accordance with the degree of nature present in the exercise environment.     

Christian–Muslim Relations in South Africa (circa 1986–2004): Charting Out a Pluralist Path

South Africa, like many other nation-states in sub-Saharan Africa, has been a multi-lingual, multi-ethnic, multi-cultural and multi-religious state for more than a century. This mosaic character of South African society stimulated Archbishop Desmond Tutu to aptly describe it as ‘the rainbow nation’. The population of South Africa's rainbow nation numbers in the region of 44.8 million, and is predominantly Christian. Other members of this nation belong to numerous other religious traditions, including Muslims, who make up roughly 1.5% (less than one million) of the total population. Despite their small numbers, Muslims have played a prominent role in South African society before and throughout the twentieth century, and their relationship with the majority Christian society, particularly within the African, Coloured and Indian communities, may generally be described as cordial.     

Maternal romantic attachment,and antenatal and postnatal mother–infant attachment in a sample of Polish women

In this exploratory study, we evaluated the relationship between a woman's self-reported romantic attachment style (as measured with The Attachment Styles Questionnaire), her experience of pregnancy, antenatal (The Maternal–Fetal Attachment Scale) and postnatal (Postpartum Bonding Questionnaire) attachment with her baby, and depressive symptomatology (The Edinburgh Postnatal Depression Scale). In the first stage of the study 162 pregnant females participated; of these, 64 were followed up in the second stage. The maternal romantic attachment style predicted attachment with the baby in the antenatal, but not in the postpartum period. The anxious-ambivalent romantic attachment style predicted more interaction with and attributing more characteristics to the foetus, secure attachment style was positively correlated with role taking, and avoidant—with attributing more characteristics to the foetus. In the postpartum period, the correlation between antenatal and postnatal attachment was only moderate; role taking during pregnancy correlated with anxiety about care for an infant. However, our study shows the association of the profile of anxious-ambivalent romantic attachment with postpartum depression, which heightens the risk of postnatal mother–infant bonding impairments.     

Infant-holding bias variations in mother–child relationships: A longitudinal study

This longitudinal study examined the associations between maternal depressive symptoms and infant holding bias in a sample of N = 43 women during three prospective sessions: during pregnancy, two months after childbirth, and when the child was 19 months of age. The majority of mothers (65.8% on average) held their children on the left side of their body at all three sessions; approximately 30% demonstrated a change in their preference, in particular between the pre- and first post-natal session. Examination of reciprocal associations between holding bias and depression revealed that prior and concurrent depression did not predict changes in holding-side biases, whereas women's holding preferences when their infant was two months old predicted change in pre- to postnatal depressive symptoms; women favouring a right-sided holding bias were significantly more likely to report increased depressive symptoms across the perinatal period, whereas a left-sided holding bias was associated with decreased depressive symptomatology.     

What do targeting positive views on ageing add to a physical activity intervention in older adults? Results from a randomised controlled trial

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.

Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).

Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.

Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.

Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults.

Case–contrast study about parent–infant interaction in a Brazilian sample of siblings of children with autism spectrum disorders

Siblings of children with autism spectrum disorders (ASD) present greater susceptibility to developmental problems, in comparison with siblings of typically developing children. The greater prevalence of mental health disorders among parents of children with ASD increases younger siblings’ vulnerability to emotional problems. The aim of this study is to compare the interaction between carers and babies aged 2 to 26 months (M = 11.7, SD = 6.9) who are siblings of children with ASD (ASD dyads) with the interaction of dyads of siblings of typically developing children (TD dyads). The protocol of Clinical Indicators of Risk for Child Development and the Coding Interactive Behaviour measures were used to evaluate interaction. ASD dyads presented higher scores of constriction in their interaction, P = .024, with babies presenting higher scores of withdrawal behavior, P = .003, and carers presenting higher scores of depressive mood, P = .008, when compared to TD dyads. The ASD dyads have interactive impairments more frequently than do the TD dyads.
