Abstract The present longitudinal follow-up study had two main goals. Firstly, this study aimed to describe aspects of maternal interactive/communicative behaviour that could be considered constitutive in sensitive responsiveness. Secondly and most importantly, it aimed to find predictive relations between characteristics of mother-infant interaction around the onset of infant intentional communication and subsequent child communicative and linguistic development. The participants were 27 Finnish-speaking mothers and their healthy first-born infants. Analyses of the amount and types of maternal and infant communicative acts as well as maternal responses to infant signals were carried out from videotaped free-play samples at the infants' age of 10 months. In addition, the CARE-Index was used to rate maternal sensitivity and infant co-operativity. At 12 months, children's communicative and linguistic skills were assessed by using the MacArthur Communicative Development Inventories and the Communication and Symbolic Behaviour Scales. At 30 months, the Reynell Developmental Language Scales III was used to assess comprehensive and expressive language. The results suggest that maternal activity in eliciting interaction and conversational interchanges is characteristic of sensitive responsiveness around the onset of infant intentionality. However, very distinctive aspects of verbal behaviour that might be constitutive in sensitive responsiveness were not found — probably as a result of considerable individual variation in all aspects of maternal as well as infant interactive/communicative behaviour that were analysed. As predictors of communicative and linguistic skills at 12 months, both maternal and infant characteristics made a significant contribution. In general, the predictive relations found were quite specific. In turn, except for the predictive validity of maternal sensitivity for comprehensive language at 30 months, later language outcomes were predicted only by children's communicative and linguistic skills at 12 months, suggesting that over time, language development becomes increasingly child-driven. Individual differences in early communicative capacities may also to some extent mask the language-facilitating effects of parenting. On the other hand, some potentially facilitating effects of parental behaviour may be elicited by the infant's well-advanced communicative skills. The importance to acknowledge transactional processes in parent-child interaction is highlighted — both in future research and clinical applications.

Postpartum psychopathology is a well-documented risk factor for impaired mother-infant bonding and thus child development. Increasingly, the focus of research in this area lies on maternal adverse childhood experiences that mothers bring into the relationship with their own baby, especially regarding the possible intergenerational transmission of traumatic experiences. Several studies showed that there is no direct link between child maltreatment and mother-infant bonding as one part of mother-child relationship, but that this link is mediated by postpartum psychopathology. To date, few studies examined differential effects between sexual, physical, and emotional abuse, and physical and emotional neglect, especially in a clinical sample. The aim of this study is to investigate whether the relationship between child maltreatment, psychopathology, and mother-infant bonding can be found for different forms of child maltreatment in patients of a mother-baby unit. Our sample consisted of 330 mothers of a mother-baby-unit in a psychosomatic clinic, who filled out self-report measures at time of admission. Mothers reported on maternal child maltreatment history with the Childhood Trauma Questionnaire, on current psychopathology with the Brief Symptom Inventory, and on mother-infant bonding with the Postpartum Bonding Questionnaire. Mediation analyses were performed with psychopathology as mediator, child maltreatment history as independent, and mother-infant bonding as dependent variable. There was no total effect of child maltreatment on mother-infant bonding. However, there were significant indirect effects of child maltreatment in general (ab = 0.09) and of the various forms of child maltreatment on mother-infant bonding via psychopathology (0.16 ≤ ab ≤ 0.34). The strongest effect was found for emotional abuse. After controlling for psychopathology, the direct effect of physical abuse on mother-infant bonding presented as a negative significant effect. This indicates that the more severe the physical abuse experienced, the better the self-reported bonding. A similar, but non-significant trend was found for sexual abuse. Our findings highlight the importance of assessing neglect forms of child maltreatment as well as abuse in women during the perinatal period. It further supports initial findings that different forms of child maltreatment can have differential effects on mother-infant bonding as one aspect of the mother-child relationship. Further research should include observational data to compare with self-report measures.

Background: The subjective experience of giving birth to a child varies considerably depending on psychological, medical, situational, relational, and other individual characteristics. In turn, it may have an impact on postpartum maternal mental health and family relationships, such as mother–infant bonding. The objective of the study was to evaluate the relevance of the subjective birth experience (SBE) for mother–infant bonding difficulties (BD) in women with mental disorders. - Methods: This study used data from N = 141 mothers who were treated for postpartum mental disorders in the mother–baby day unit of the Psychosomatic University Clinic in Dresden, Germany. Patients' mental status at admission and discharge was routinely examined using a diagnostic interview (SCID I) and standard psychometric questionnaires (e.g., EPDS, BSI, PBQ). Both, the SBE (assessed by Salmon's Item List, SIL) as well as medical complications (MC) were assessed retrospectively by self-report. The predictive value of SBE, MC, as well as psychopathological symptoms for mother–infant BD were evaluated using logistic regression analyses. - Results: About half of this clinical sample (47.2%) reported a negative SBE; 56.8% of all mothers presented with severe mother–infant BD toward the baby. Mothers with BD showed not only significantly more depressiveness (EPDS: M = 16.6 ± 5.6 vs. 14.4 ± 6.2*), anxiety (STAI: M = 57.2 ± 10.6 vs. 51.4 ± 10.6***), and general psychopathology (BSI-GSI: M = 1.4 ± 0.7 vs. 1.1 ± 0.6**) compared to women without BD, but also a significantly more negative SBE (SIL: M = 79.3 ± 16.2 vs. 61.3 ± 22.9***). Moreover, the SBE was the most powerful predictor for BD in univariate and multiple logistic regression analyses [OR = 0.96*** (95% CI 0.94–0.98) vs. OR = 0.96** (95% CI 0.93–0.98)], even when univariate significant predictors (e.g., current psychopathology and MC during birth) were controlled. - Conclusions: A negative SBE is strongly associated with mother–infant bonding in patients with postpartum mental disorders. It needs to get targeted within postpartum treatment, preferably in settings including both mother and child, to improve distorted mother–infant bonding processes and prevent long-term risks for the newborn. Furthermore, the results highlight the importance of focusing on the specific needs of vulnerable women prior to and during birth (e.g., emotional safety, good communication, and support) as well as individual factors that might be predictive for a negative SBE.

John Bowlby made a profound contribution to the field of early parenting with his theory of attachment. He suggested that attachment theory has universal applicability. However, it has been argued that attachment theory is based upon a Western worldview, and as such, lacks applicability in cross-cultural contexts. In light of this objection, this study aimed to examine the relevancy of attachment theory within the South African context. In order to do this, a qualitative research design, employing focus groups, was set up to explore isiZulu-speaking mothers’ constructions of infant-caregiver relationships. Participants were recruited from two Non-Governmental Organizations (NGOs) in KwaZulu-Natal. Each participant partook in three focus groups. The focus group data was analyzed using a form of thematic analysis. The group discussion provided support for attachment theory in the South African context. However, there appeared to be some cultural variations in the ways in which the attachment relationship is carried out within this context. In particular, it appeared that isiZulu-speaking mothers employ physical touch and a rapid response style with their infants. Furthermore, evidence emerged to suggest that there are certain barriers to the attachment relationship in South Africa. Finally, this research study showed that urbanization has had an important impact on parenting. As such, from this research, it can be concluded that attachment interventions are useful in South Africa, yet these may need to occur alongside other interventions. There is also room for further research to explore understandings of attachment within broader population groups, including fathers and grandmothers. / Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

L’esperienza di aspettare e di essere genitore di due gemelli è innegabilmente diversa rispetto alla gravidanza alla genitorialità nel caso di un singolo bambino. La nascita gemellare è associata a conseguenze mediche, sanitarie, socio-emotive, psicologiche e dello sviluppo. Lo scopo di questo lavoro è stato quello di aggiungere conoscenze rispetto agli aspetti unici legati alla gravidanza gemellare e alla genitorialità. Ho esaminato il modo in cui le future mamme vivono la loro gravidanza e come le madri sperimentano l’essere genitori di due gemelli e come queste interagiscono con i loro bambini nel periodo post-partum. Per studiare meglio l'esperienza di aspettare e di essere madre di due gemelli, i risultati sono stati confrontati con la letteratura esistente e sono stati utilizzati diversi progetti di ricerca. È stata valutata la validità e le proprietà psicometriche della versione italiana del Baby Care Questionnaire; è stato valutato se l'esperienza unica di un gemello in attesa potesse influenzare negativamente l'attaccamento prenatale; è stato esplorato l'impatto della nascita gemellare sull'interazione madre-figlio nel primo periodo post-partum. Questa tesi ha stabilito che le madri di gemelli hanno esigenze particolari e affrontano sfide uniche. Le madri di gemelli sembrano essere meno adattate dal punto di vista psicologico alla loro gravidanza in termini di basso livello di attaccamento prenatale. Anche la costruzione di una relazione stretta e positiva potrebbe essere più difficile nel caso dei gemelli. / The experience of expecting and parenting twins is undeniably different from that of a singleton pregnancy and parenthood. Twin births are associated with medical, health care, socio-emotional, psychological and developmental consequences. The aim of this work was to add knowledge concerning the unique aspects of expecting and parenting twins. I examined the way the mothers-to-be live their pregnancy as well as how mothers experience parenting twins and interact with their babies in the post-partum period. To better investigate the unique experience of expecting and parenting twins, results were compared with the existing literature and different research design were used. It was evaluated the validity and the psychometric properties of the Italian version of the Baby Care Questionnaire; it was investigated if the unique experience of expecting twin may adversely affect prenatal attachment; it was explored the impact of twin birth on mother-child interaction in the early post-partum period. This thesis established that mothers of twins have unique needs and face unique challenges. Mothers of twins seems to be less psychological adjusted to their pregnancy in terms of lower level of prenatal attachment. Also the building of a close and positive relationship could be more difficult in the case of twins.

La naissance est l’une des étapes les plus délicates à laquelle les nouveau-nés mammifères doivent faire face. Le nouveau-né doit opérer des changements physiologiques et comportementaux pour s’adapter à l’environnement aérien, et l’un des premiers défis est d’ingérer du colostrum et du lait. Il est surprenant que la nature des stimuli et les mécanismes impliqués dans le déclenchement de la tétée soient encore mal connus, alors que la survie du nouveau-né est conditionnée par le succès de la première tétée. Par conséquent, cette étude a pour but de comprendre comment un nouveau-né immature et inexpérimenté réussit à s’orienter vers une tétine, à la saisir et à la téter de façon efficace? Cette question générale est posée chez la souris en focalisant sur : i) la nature des substrats chimiques utilisés par les souriceaux pour atteindre les tétines maternelles ; ii) la variation de la puissance attractive de ces substrats au cours du développement ; et iii) l’implication des effets de l’expérience dans l’établissement des réponses adaptatives précoces. Premièrement, nos résultats mettent en lumière que les odeurs mammaires de femelles allaitantes induisent plus d’approches et de saisies de la tétine chez les souriceaux que celles émanant de femelles non allaitantes. Deuxièmement, les odeurs de liquide amniotique et de lait déclenchent la première saisie orale de la tétine chez des souriceaux à la naissance, alors que les odeurs de salives maternelle et infantile n’induisent ce comportement qu’après une brève expérience de tétée. Troisièmement, les souriceaux âgés de 0, 2 et 6 jours postnatals (P), ayant eu une expérience de tétée, affichent une attraction sélective envers des odeurs de laits collectés en début de lactation plutôt qu’en fin de lactation, alors que les souriceaux plus âgés P15 ne montrent aucune réponse sélective envers ces odeurs. En résumé, certains substrats biologiques présents sur les tétines de femelles allaitantes sont immédiatement attractifs après la naissance, tandis que d’autres ont besoin d’être appris pour être réactogènes. Par conséquent, la réponse initiale de recherche de la tétine chez le souriceau est contrôlée par des processus d’apprentissage postnatal. A ce stade, l’implication de l’apprentissage prénatal et de processus prédisposés n’a pu être prouvée, bien qu’elle ne soit pas exclue. Ces résultats montrent des capacités d’apprentissage sophistiquées chez le souriceau nouveau-né / Birth is one of the most delicate periods mammalian infants have to deal with. Newborns have then to adapt physiologically and behaviorally to the aerial environment, and one of their first challenges is to ingest colostrum and milk. It is paradoxical that the survival of pups is conditioned by the success of this first suckling, and that we have so little understanding of the stimuli that underlie and promote it. Thus, the present work aims to contribute to answer how immature and naïve newborns do manage to orient to a nipple, to grasp it, and to suckle efficiently? This general issue will be addressed in the mouse in focusing on: i) the nature of the chemical substrates that newborn mice use to reach nipples; ii) whether the attractive potency of these substrates changes as a function of development; and iii) whether exposure effects underly the establishment of early adaptive responses? The results highlight that mammary odors of lactating females are more behaviorally active for newly born pups than those of non-lactating females. Secondly, amniotic and milk odors provoke the first nipple grasping in newborns right at birth, while maternal and pup salivary odors induce this behavior after short sucking experience. Thirdly, younger pups on postnatal day (P) 0, 2 and 6 (with sucking experience), display a selective orientation toward the odor of milk collected during early-lactation rather than to the odor of late-lactation milk, whereas older pups P15 do not exhibit any selective attraction to these odors. To summarize, some of the biological substrates which are present on a nursing mouse nipples are attractive immediately after birth, while some others need to be postnatally learned to be active. Thus, the initial nipple search response of mouse pups is controlled by processes involving postnatal learning. At this stage, the involvement of prenatal learning and of predisposed processes that do not depend on previous exposure effect are not conclusive, although not excluded. These results show highly sophisticated learning abilities in a newborn mammal

Les nouveau-nés prématurés sont à risque de développer des séquelles neurodéveloppementales pouvant se manifester de la petite enfance jusqu’à l’âge adulte. La relation mère-enfant précoce figure parmi les facteurs pouvant améliorer leur neurodéveloppement. La principale composante de cette relation est la sensibilité maternelle, soit la capacité de détecter, d’interpréter et de répondre rapidement aux besoins du nouveau-né. Cependant, en raison de l’immaturité des nouveau-nés prématurés ainsi que du stress et de l’anxiété vécus par les mères pendant l’hospitalisation, celles-ci sont à risque de développer une sensibilité maternelle sous-optimale. De par leurs compétences, leurs valeurs et leurs activités réservées, les infirmières à l’unité de soins intensifs néonatals (USIN) jouent un rôle de premier plan pour favoriser la sensibilité maternelle dès l’hospitalisation des nouveau-nés prématurés. Les données scientifiques actuelles ne sont suffisantes ni en quantité ni en qualité afin d’orienter les interventions que pourraient concrètement réaliser les infirmières auprès de la dyade mère-nouveau-né prématuré afin de favoriser de façon très précoce, soit dès l’hospitalisation, la sensibilité maternelle. Le but de la thèse comportait deux volets : 1- développer une intervention infirmière très précoce selon une approche combinant la théorie et les données empiriques pour favoriser la sensibilité maternelle et le neurodéveloppement des nouveau-nés prématurés à l’USIN; et 2- mettre à l’essai et évaluer la faisabilité, l’acceptabilité et estimer les effets préliminaires de l’intervention infirmière sur la sensibilité maternelle et le neurodéveloppement des nouveau-nés prématurés à l’USIN. Une intervention infirmière novatrice multifactorielle nommée GP_Posit a été développée. GP_Posit est une intervention individuelle hebdomadaire durant laquelle l’infirmière crée une relation de participation guidée avec la mère, dans un contexte de participation aux soins et au positionnement du nouveau-né prématuré. Basée sur la Théorie de l’Attachement, la Théorie de la Participation Guidée et la Théorie Synactive du Développement, GP_Posit est principalement conçue afin de favoriser la sensibilité maternelle et le neurodéveloppement du nouveau-né prématuré. Ensuite, une étude pilote randomisée à deux groupes a été menée dans une USIN de niveau III d’un centre hospitalier universitaire mère-enfant. Au total, 20 dyades composées de mères et de leur nouveau-né prématuré ont été recrutées et randomisées au groupe expérimental (GP_Posit; n=10) ou au groupe contrôle (soins standards; n=10). Les résultats montrent que GP_Posit est faisable et acceptable pour les mères de nouveau-nés prématurés ainsi que pour l’équipe de recherche. Toutefois, au niveau de la faisabilité et l’acceptabilité du devis relatif à l’essai clinique randomisé, des difficultés ont été rencontrées au niveau du recrutement et la collecte de données au post-test. Les effets préliminaires estimés montrent une tendance vers un effet large indiquant une augmentation de la sensibilité maternelle chez les mères du groupe expérimental. Quant à l’effet préliminaire sur le neurodéveloppement, les nouveau-nés prématurés du groupe contrôle étaient légèrement favorisés. Une seconde étude pilote permettrait de mettre à l’essai des procédures modifiées de recrutement et collecte de données au post-test. Éventuellement, un essai contrôlé randomisé multicentrique à grande échelle permettra d’apprécier davantage les effets de GP_Posit sur la sensibilité maternelle et le neurodéveloppement des nouveau-nés prématurés. / Preterm infants are at risk of neurodevelopmental impairments which can manifest from infancy through adulthood. The early mother-infant relationship is one of the factors that can improve their neurodevelopment. The main component of this relationship is maternal sensitivity, that is the mother’s ability detect, interpret and respond in an appropriate and timely manner to her infant’s needs. However, due to the immaturity of preterm infants as well as the stress and anxiety experienced by mothers during hospitalization, they are at risk of developing suboptimal maternal sensitivity. Neonatal nurses play a key role and have the necessary skills to promote maternal sensitivity in the neonatal intensive care unit (NICU). However, the current evidence is neither sufficient nor of sufficiently good quality to guide the interventions that could be implemented by neonatal nurses to promote maternal sensitivity in the NICU. The aim of the thesis was twofold: 1- develop an innovative very early nursing intervention using an approach combining theory and empirical data to promote maternal sensitivity and neurodevelopment of preterm infants in the NICU; and 2- to implement and assess the feasibility, acceptability and estimate of the preliminary effects of this nursing intervention on maternal sensitivity and neurodevelopment of preterm infants in the NICU. A very early multifaceted nursing intervention named GP_Posit was developed. GP_Posit is a weekly individual intervention where nurses create a guided participation relationship with mothers, in a context of participation in care and positioning of the preterm infant. Based on Attachment Theory, Guided Participation Theory and Synactive Theory of Development, GP_Posit is primarily designed to promote maternal sensitivity and neurodevelopment of the preterm infant. A two-group randomized pilot study was conducted in a level III NICU of a mother-infant teaching hospital. A total of 20 dyads composed of mothers and preterm infants were recruited and randomized to the experimental group (GP_Posit; n = 10) or control group (standard care; n = 10). Results show that GP_Posit is feasible and acceptable for mothers of preterm infants as well as for the research team. Regarding the feasibility and acceptability of the randomized controlled trial study design, challenges were encountered in the recruitment and post-test data collection procedures. The preliminary effects showed a trend towards a large effect in increasing maternal sensitivity in experimental group mothers. As for the preliminary effect on neurodevelopment, preterm infants in the control group had an advantage. A second pilot study would be the opportunity to test modified recruitment and post-test data collection procedures. Eventually, a large-scale, multicenter randomized controlled trial would allow a better understanding of the effectiveness of GP_Posit on maternal sensitivity and preterm infant neurodevelopment.

This qualitative and exploratory research study was developed based on Edmund Husserl?s phenomenology and guided by principles of Humanistic psychology, specifically Carl Roger?s Person Centered Approach. It aimed to apprehend the experience of 13 mothers who gave birth to their first child during the past 18 months, about the meaning of singing to their infants. The researcher spoke to each of the participants, all with a college education, during a dialogical encounter, and immediately afterwards wrote a comprehensive narrative to register her comprehension regarding that mother?s experience, based on her own impressions. A narrative-synthesis and a creative synthesis were constructed based on the narratives to enable a phenomenological process of analysis that presupposes three phases: description, comprehension and interpretation of the experience. The structural elements that emerged from the mothers' experience of singing to their infants are: (a) a means of communication hugging their infant with their song; (b) the establishment of an emotional bond with their infant; (c) a way to better know their infant as it develops; (d) a means of recognizing themselves as mothers; (e) a form of sharing personal values and family customs; (f) a creative way of expressing themselves, and (g) a possibility of personal growth. The meaning of this experience enables further reflections regarding human relationships from a psychological viewpoint and can stimulate dialogues with other areas of knowledge. / Las pesquisas que abordan el canto materno se preocupan en investigar c?mo y por qu? las canciones son facilitadoras de la comunicaci?n madre-beb?, dando atenci?n principalmente a los aspectos ac?sticos y socioculturales.
