| Today's fathers are increasingly more involved with their children. During the preschool years, rough-and-tumble-play (RTP; including play-fighting) is a significant aspect of paternal interaction style. A few studies suggest that this type of play is linked to children's social adaptation. However, many contradictions remain in the current literature, particularly concerning the link between the quantity of father-child RTP and social adaptation measures, RTP quality indicators and their measurement, and gender differences. There is also a debate regarding the optimal control level (or mutuality) during play. Moreover, very few studies have investigated the link between father-child RTP and children's anxiety/withdrawal.;The current thesis has four objectives: 1) to verify the presence of a link between father-child play-fighting quantity and preschooler's social adaptation measures (i.e., social competency, aggressiveness/irritability, physical aggression and anxiety/withdrawal); 2) to verify if mutuality or control measures moderate the relationship between father-child play-fighting quantity and social adaptation; 3) to explore the potential role of other play-fighting quality cues; 4) to clarify the role of child gender. The sample consists of 100 father-child dyads from the Montreal region.;Correlational analyses suggest that the frequency and duration of play-fighting are not directly linked to children social adaptation. The regressions for moderation models indicate that father-child mutuality in play-fighting initiations, as well as the fear expressed by the child during play, moderate the relationship between play-fighting duration and the preschooler's social competency. Mutuality also moderates the link between play duration and child aggressiveness/irritability. Although fathers do not report a higher frequency or duration of play-fighting according to their children's gender, post-hoc analyses show that three out of four moderating models are significant only for the boys.;The data is interpreted according to evolutionary and developmental theories. It is argued that a measure of competition could shed light on the relationship between aggressiveness and social competency in social adaptation, and that these two variables may not systematically be opposed as it is commonly perceived in RTP literature.;Keywords: rough-and-tumble-play, play-fighting, social competency, aggressiveness, physical aggression, anxiety, father, child, preschool age, moderation... |
