This study attempted to investigate father attachment using the dual primary attachment figure model by examining caregiving and exploration behaviors of mothers and fathers as they relate to attachment security utilizing an archival data set of 177 young adult females. A subsequent factor analysis of the involvement scales revealed four distinct items creating the caregiving variables (one for mother and one for father) and six items creating the exploration variables. Results showed that mothers engaged in caregiving and exploration behaviors more than fathers, but their exploration predicted mother attachment more than caregiving. Fathers engaged in more caregiving than exploration, but it was their involvement in exploration that was more strongly related to father attachment. These findings, which provide partial support for the dual primary attachment figure model, suggest that father exploration is a cornerstone for the father-child attachment relationship, but also predictive of mother-child attachment. Future studies should include observational assessments of father attachment as well as exploration in current assessments of father attachment.

Attachment theory is a core theory of child development. The theory proposes a framework to understand how children’s early relationships to their caregiver shape children’s lifelong development. Most attachment research, however, is limited to categorical assessments of infant-mother attachment. This results in a reductionist understanding of children’s development, one that rests on a number of questionable assumptions. From an assessment perspective, categorical measures of attachment assume that all children fit neatly into a fixed number of categories, and that all children within a category present similar attachment behaviors. From a developmental perspective, a focus on infant attachment assumes little change in children’s caregiving environments, and this, despite evidence showing that changes may occur between infancy and the preschool years. Such changes influence child-caregiver attachment relationships. From a caregiver perspective, children’s relationships with their mothers are influential, but they do not span the gamut of children’s early relationships. Fathers, for example, are increasingly involved in child rearing and are influential in children’s development. This dissertation sought to overcome these limitations through the use of the Preschool Attachment Rating Scales (PARS), a novel, continuous measure of child-caregiver preschool attachment. The first study demonstrated the reliability and validity of the PARS as a measure of child-mother and child-father preschool attachment. This study examined the inter-rater reliability, the convergent validity, the construct validity, the predictive validity, and the incremental validity of the PARS. The second study used a longitudinal design to examine the independent and interactive influence of child-mother and child-father attachment in the preschool years on boys’ and girls’ externalizing behaviors in middle childhood. This latter study showed that the prediction of externalizing behavior varied as a function of children’s and parents’ genders, as well as the attachment pattern (e.g., security, avoidance). Taken together, this dissertation shows that a continuous measure of attachment can help uncover the complexity of different attachment patterns, and in turn, provide a more nuanced understanding on how such patterns affect children’s social, emotional, and psychopathological development.

Depuis plusieurs décennies, on reconnaît l’existence d’une complémentarité des rôles père et mère dans le développement de l’attachement de l’enfant. La mère étant davantage impliquée dans les soins, le père se spécialise dans la sphère exploration, le jeu et le respect des règles. Les études démontrent une association entre la qualité d’attachement des parents et de l’enfant avec un effet plus fort chez les mères, un phénomène discuté sous le vocable transmission intergénérationnelle de l’attachement. De nos jours, on assiste à un plus grand partage des tâches liées à l’enfant et le père peut être perçu comme une figure de soin. Cette étude a été menée à partir d’un échantillon normatif de familles biparentales hétérosexuelles (N = 182) à proximité de Montréal. Le premier objectif était d’examiner l’association entre l’attachement des parents évalué avec le Relationship Scale Questionnaire (RSQ) et celui de l’enfant évalué lors de la Procédure de la Situation Étrangère (SSP). Le second objectif était d’examiner le rôle modérateur du temps passé par les parents avec l’enfant. Contrairement à nos prédictions, les résultats ne démontrent aucune association significative entre le RSQ maternel et la SSP mère-enfant. Toutefois, les pères avec qui l’enfant a développé un attachement sécurisé se distinguaient par un score de sécurité significativement supérieur au RSQ. Ensuite, le temps père-enfant n’était pas associé à l’attachement père-enfant, mais l’était avec l’attachement mère-enfant. Concernant cette association, le temps total passé par le père avec l’enfant était négativement associé à la résistance au contact mère-enfant, positivement associé au type Sécurisé et négativement associé au type Résistant. Enfin, la quantité de temps que les deux conjoints passent ensemble avec l’enfant était positivement associée au type Sécurisé et négativement associée au type Désorganisé lors de la SSP mère-enfant. Au terme de cette étude, nous croyons que le RSQ évalue des dimensions différentes de celles habituellement associées avec la SSP, ce qui en fait un choix moins recommandé pour examiner l’association entre l’attachement du parent et de l’enfant. La quantité de temps passé par le père avec l’enfant ne semble pas déterminante dans le développement de l’attachement père-enfant. Toutefois, nos données suggèrent des bénéfices directs et indirects associés au temps passé par le père avec la dyade mère-enfant sur le lien d’attachement mère-enfant. / Since a few decades, researchers have acknowledged the evidence of a complementarity between the roles of the father and the mother in the development of infant attachment. While the mother plays a main role in caregiving, the father tends to promote exploratory behavior, respect of rules and frequently act has a playmate. Numerous studies have shown an association between caregiver’s attachment and infant’s attachment with a stronger effect for mothers, which is widely discussed in terms of intergenerational attachment transmission. Nowadays, between the two parents, there is a less hermetic division of tasks associated with caregiving and there is a growing agreement that the father can be perceived as a secure figure. We studied a normative sample of 182 heterosexual biparental families living in the Montreal area. The first objective was to examine the association between parent’s attachment assessed with the Relationship Scale Questionnaire (RSQ) and infant-parent attachment measured with the Strange Situation Procedure (SSP). Our second objective was to look at the role of time spent by the parent with his child as a moderator of the above-mentioned association. Unlike our predictions, no significative association was found between the maternal RSQ and the infant-mother SSP. Nevertheless, fathers with whom a secured attachment is developed distinguish themselves by a significantly higher security score on the RSQ. Furthermore, while the time spent by the father with the infant hasn’t been linked with father-infant attachment, it was, however, associated with mother-infant attachment. Concerning this association, the time spent by the father with his child was negatively associated with resistance during the mother-infant SSP, positively associated with Secure type and negatively associated with Resistant type. Finally, the time the parents spent together with the child was positively associated with the Secure type and negatively associated with Disorganize attachment. At this study’s conclusion, we believe the RSQ might assess dimensions other than the ones usually associated with the SSP, which would make this instrument less recommended in future research on attachment transmission. The time the father spends with his child doesn’t seem to influence his attachment. However, our results suggest the time spend by the father with the mother-infant dyad might have direct and indirect benefices on the mother-infant attachment.
