This study reported an Outcome Mediation Cascade evaluation of the Changing Lives Program (CLP), a positive youth intervention. This study examined the effects of participation in the CLP on positive outcomes (Personal Expressiveness and Well-Being) and negative outcomes (Internalizing and Externalizing problem behaviors) as mediated by Identity Distress. 137 females and 101 males comprised the sample of this study, which draws from archival data of adolescents in alternative high schools in Miami. Findings indicated that the hypothesized model fit the data (χ2 (11) = 14.544, p = .020; RMSEA = .04; CFI = .995; SRMR = .028). Findings also provided preliminary evidence consistent with the hypothesis that in addition to having effects on targeted positive outcomes, PYD interventions are likely to have progressive cascading effects on untargeted problem outcomes.

<p>Various aspects of elementary school children's behavior problems were investigated in four studies. In Study I, teachers’ perceived low control over the classroom situation and a custodial teacher orientation were associated with teachers' (n = 86) preferences for authoritarian strategies (e.g., firm commands) in handling externalizing child behavior problems. Further, perceived high control and a humanistic teacher orientation were associated with non-authoritarian strategies (e.g., reasoning with students). In Study II, the aim was to investigate prospectively teacher-child interactions and teacher-child perceptions of the relationship between children with externalizing (n=26) and internalizing (n=25) behavior problems and unproblematic children (n=44) in the first grade. Children with behavior problems had a higher frequency of negative teacher relationships than unproblematic children. Observed conflictual children-teacher interactions contributed to negative teacher relationships independent of problem status. The moderating effects of social competence were small. In Study III, the principal aim was to investigate whether the children’s social competence, relationships with teachers and behavior with peers functioned as protective or exacerbating factors regarding the adaptation of children with behavior problems. Children with externalizing and internalizing behavior problems, in comparison with unproblematic children, were lower in social competence, school achievement and peer acceptance in sixth grade. There were moderating and independent effects of social competence and teacher and peer relationships on outcomes, but these were mainly restricted to those children with internalizing problems. The primary aim of Study IV was to investigate the social and school adjustment of six-grade children experiencing feelings of loneliness and low peer acceptance. Totally, 808 children participated, and 323 of these children had been followed from grade 1 to grade 6. The results indicated that loneliness was most strongly predicted by early internalizing problems, whereas poor acceptance was predicted by early externalizing problems and poor social competence. Associations between loneliness and low peer acceptance and other adjustment difficulties were also observed. In conclusion, children with behavior problems risk negative relationships as well as other adjustment problems. Early interventions are important in strengthening the protective factors.</p>

Children who express externalizing behaviors in school are at greater risk of school failure and peer rejection. They are also at greater risk of developing antisocial behaviors, addiction to drugs, mental health problems and delinquency. Many teachers experience difficulties in working with pupils expressing externalizing behaviors. The aim of this thesis is to evaluate a classroom behavior management program called Comet. The main principle of Comet is to get the teacher to use effective strategies when the pupil who is targeted for intervention, and the rest of class, are behaving appropriately and inappropriately. Two versions of the program are evaluated in the thesis: Comet for teachers (Comet-T) and Comet for parents (Comet-P). Three studies are committed to evaluate Comet-T. In the first study Comet-T was compared to an active control group. 100 children (aged 8) were randomized into Comet-T or the control group. At post test and follow-up Comet-T received a better results in reducing externalizing problems, peer problems and teacher behavior management. An analysis of mediators showed that changes in teacher behaviors mediated externalizing behavior. In the second study, children (aged 6 -13) were randomized into two groups. 44 pupils received Comet-T and 42 pupils received a combined intervention consisting of Comet-T at school and Comet-P at home. At post test and follow-up the results show that the combination of Comet-T and Comet-P reduced the externalizing behaviors at home more than Comet-T (only). However, there were no significant differences between the two conditions regarding decrease in externalizing behaviors at school. In the third study Comet-T was compared to a brief version called Comet-TB. At post test Comet-TB had a greater reduction of externalizing behaviors compared to Comet-T. The studies conclude that teachers can use behavior management techniques to decrease externalizing behaviors in the classroom. Furthermore, teachers cannot rely on parent management programs in order to decrease externalizing problems in school. Instead, behavior problems in school need to be solved within school settings. Finally, even a brief program can be effective in order to decrease externalizing behaviors.

Différents éléments peuvent influencer le fonctionnement socio-émotionnel des enfants et agir comme facteurs de protection ou facteurs de risque. Il est maintenant bien reconnu que ces facteurs proviennent d’éléments propres à l’enfant ainsi que d’aspects provenant de l’environnement dans lequel il grandit. Cette thèse se centre sur les facteurs intrinsèques et environnementaux les plus étudiés concernant le développement socio-émotionnel des enfants durant la petite enfance: le tempérament de l’enfant et la qualité des relations mère-enfant. Peu d’études se sont intéressées à l’interface entre le tempérament et la qualité des relations mère-enfant mesurés dans la petite enfance pour prédire le fonctionnement socio-émotionnel à l’âge scolaire. Pourtant, l’âge scolaire est marqué d’une étape de transition des plus saillantes du développement des enfants, c’est-à-dire l'entrée scolaire. L'ajustement socio-émotionnel des enfants au cours des premières années d’école est l'un des principaux facteurs influençant leur adaptation scolaire (Robson et al., 2020). Il est donc essentiel de comprendre pourquoi certains enfants fonctionnent mieux que d'autres sur ce plan durant l’âge scolaire. Le premier article explorait le rôle modérateur de la qualité des interactions mère-enfant, observée à 2 ans, dans la relation entre la tendance à la colère des enfants et leurs comportements intériorisés, extériorisés et prosociaux à l’entrée scolaire. Les résultats ont montré que la tendance à la colère des tout-petits prédisait des difficultés socio-émotionnelles chez ceux-ci, principalement dans le contexte d’une meilleure qualité d’interactions mère-enfant. Le deuxième article examinait les liens prédictifs entre le soutien maternel à l’autonomie (observé à 15 mois) et les trajectoires des comportements intériorisés et extériorisés des enfants mesurés de 2 à 7 ans, en contrôlant les dimensions négatives du tempérament des enfants. Les résultats du deuxième article ont montré que plus les mères soutenaient l’autonomie de leur enfant, plus les comportement intériorisés augmentaient lentement dans les années subséquentes et plus les comportements extériorisés diminuaient rapidement. / Different elements can act as protective or risk factors for child socioemotional functioning. It is now well recognized that these elements come from child-specific as well as environmental factors. This thesis focuses on the most studied intrinsic and environmental factors concerning child socioemotional development during toddlerhood: child temperament and mother-child relationship quality. Few studies have investigated the interplay between temperament and mother-child relationships in toddlerhood in the prediction of child socioemotional functioning in the early school years. Yet, this period includes a major developmental transition, namely school entry. Young children’s socioemotional adjustment during this period is one of the main factors influencing their school adaptation (Robson et al., 2020). It is therefore essential to understand why some children adapt better than others in early school years. The first article explored the moderating role of mother-child interactions quality, observed at 2 years old, in the association between child anger proneness and internalizing, externalizing and prosocial behaviors at school entry. The results showed that child anger proneness predicted socioemotional difficulties, primarily in the context of better mother-child interactions quality. The second article examines the predictive links between maternal autonomy support (observed at 15 months) and the trajectories of internalizing and externalizing behaviors measured from 2 to 7 years, while controlling for the negative dimensions of child temperament. The results showed that the more mothers supported their child's autonomy, the more internalizing behavior increased slowly and the more externalizing behavior decreased rapidly in later years.

Il y a consensus qu’approximativement la moitié des différences individuelles liées à l’agression physique sont héritées. Cependant, les premières manifestations comportementales et sociales de cette propension génétique demeurent inconnues. Cette étude vise à tester l’hypothèse selon laquelle, les scores polygéniques liés à l’agression (SPGAG) et au trouble du déficit de l’attention/hyperactivité (TDAH; SPGTDAH), tous deux ayant précédemment été associés à l’agression physique à l’âge scolaire, se manifesteraient d’abord par des comportements externalisés et des expériences adverses à la petite enfance. Les données génétiques de 718 participants (44,6 % garçons) de l’Étude longitudinale du développement des enfants du Québec (ELDEQ) ont été utilisées pour estimer les SPGs. L’agression physique à l’âge scolaire a été rapportée à six reprises entre 6 et 13 ans par des enseignants indépendants. Les mères ont rapporté les comportements externalisés (agression physique, hyperactivité, opposition) et les expériences adverses (difficultés avec les pairs, pratiques parentales hostiles et coercitives) à trois occasions entre l’âge de 3½ et 5 ans. Les résultats indiquent que ces deux SPGs prédisent l’agression physique à l’âge scolaire. Néanmoins, seules les difficultés avec les pairs expliquent l’association entre le SPGAG et l’agression physique. L’hyperactivité, l’opposition et les pratiques parentales hostiles et coercitives sous-tendent toutes, de façon séparée, l’association entre le SPGTDAH et l’agression physique à l’âge scolaire, bien que seule l’hyperactivité ait une contribution unique lorsque ces construits sont examinés simultanément. Ces résultats contribuent à décrire comment l’étiologie génétique liée à l’agression physique se manifeste à la petite enfance, identifiant ainsi des cibles précoces d’intervention. / There is now a consensus in the literature suggesting that approximately half of the individual differences related to physical aggression (PA) are inherited. However, the behavioral and social early manifestations of this genetic propensity remain unknown. This study aims to test the hypothesis that polygenic scores related to aggression (PGSAGG) and attention deficit hyperactivity disorder (ADHD; PGSADHD), both of which were previously shown to be associated with PA during school-age, would be first phenotypically expressed as externalized behaviors and adverse experiences in early childhood. The genetic data of 718 participants (44,6% boys) from the Quebec Longitudinal Study of Child Development (QLSCD) were used to estimate the SPGs. PA in school age was reported up to six times between 6 and 13 years old by independent teachers. Externalized behaviors (PA, hyperactivity, opposition) and adverse experiences (difficulties with peers, harsh and coercive parenting practices) were reported by mothers on three occasions between the ages of 3½ and 5 years old. Results indicate that both SPGs predicted PA in school age. However, only difficulties with peers explain the association between PGSAGG and PA. Hyperactivity, opposition, and harsh and coercive parenting practices in early childhood all separately partially mediated the association between PGSADHD and PA in school age, although only hyperactivity has a unique contribution when these constructs are examined simultaneously. These findings contribute to describing how PA measured genetic etiology ascertained by the PGS come to be first phenotypically expressed in early childhood, identifying early intervention targets for interventions.
