Increased mental health difficulties were reported in Canadian children as a result of the Covid-19 pandemic. Accordingly, the pandemic has impacted families as well. The purpose of this thesis was: 1) to examine fluctuations in children’s mental health symptoms and mindful parenting across the 2020-2021 academic year; 2) to examine whether children’s symptoms of inattention and hyperactivity at the beginning of the 2020-2021 academic year were associated with mindful parenting at the end of the academic year; 3) to examine whether children’s depressive and anxiety symptoms at the end of the year moderated this relationship and; 4) to examine how child age and gender affected these relationships. Parents of 114 young children in a large Canadian city participated in this study in the Fall of 2020 and the Spring of 2021. Parents completed several self-report scales used to measure children’s mental health symptomatology and mindfulness in parenting. While there were no significant changes in children’s mental health symptoms or mindful parenting across the time points, children’s symptoms of inattention and hyperactivity were significantly, negatively associated with mindful parenting across the pandemic year, and children’s depressive symptoms moderated this relationship. Specifically, when children’s depressive symptoms were low or average it was found that higher symptoms of inattention and hyperactivity were associated with lower levels of mindful parenting among parents of young girls. Results may inform practitioners about which families require additional support during the pandemic and beyond.

In psychological research, positive developmental outcomes in young adulthood are often conceptualized as the absence of psychological symptoms. However, positive outcome may be better understood as high levels of subjective wellbeing and adaptive interpersonal, occupational, and educational functioning. Nevertheless, a comprehensive model that takes into account multiple facets of youth behavior and transactional relations between youth and their environments as predictors of adjustment in young adulthood is lacking. Prior evidence implicates internalizing and externalizing behaviors in the development of subjective wellbeing, and emotion regulation as a reliable predictor and/or correlate of both internalizing and externalizing behaviors. Parenting behaviors in childhood and youth substance use represent other shared risk or resilience factors that likely contribute to internalizing and externalizing behaviors, as well as subjective wellbeing and adaptive functioning outcomes in young adulthood. The current study examined an existing sample of youth who were recruited at ages 10-12 and were assessed again at ages 16 and 25. Analyses aimed to (a) identify subgroups of youth who vary in frequency and quality of internalizing and externalizing symptoms and emotion regulation at ages 10-12 and 16 using latent class analyses, (b) examine stability of and transitions in class membership from classes at ages 10-12 to classes at age 16 using latent transition analysis, (c) investigate parenting behaviors as predictors of stability and transitions among classes, and (d) investigate whether classes differ in cross-sectional and prospective levels of substance use, as well as subjective wellbeing and adaptive functioning in young adulthood. Results demonstrated that a 4-class model best fit the data at both time points. Classes of youth with (a) low symptoms and high emotion regulation; (b) low internalizing, moderate externalizing, and high emotion regulation; and (c) moderate internalizing, high externalizing, and low emotion regulation emerged at both time points. The fourth class at ages 10-12 was characterized by high social withdrawal and moderate hyperactivity and emotion regulation, and the fourth class at age 16 was characterized by moderate internalizing, low externalizing, and low emotion regulation. Latent transition analyses revealed transitions from several symptom classes at ages 10-12 into the age 16 Low Symptoms/High Emotion Regulation class, and also stability and transitions to other symptom classes. Predictor analyses indicated that levels of parenting behaviors (maternal and paternal acceptance, child-centeredness, use of guilt and anxiety to control youth, lax discipline, and nonenforcement of rules) were associated with transitions among and stability within classes, but findings were dependent on levels of internalizing and externalizing symptoms among classes. Substance use differed cross-sectionally and prospectively across classes based on the substances considered. Further, subjective wellbeing was higher among age 16 classes characterized by low internalizing symptoms, low or moderate externalizing symptoms, and high emotion regulation. Adaptive functioning in select domains was also differentially associated with classes at both time points, with youth in the Low Symptoms/High Emotion Regulation classes experiencing better outcomes in certain areas. Results indicate that distinct classes of youth internalizing and externalizing symptoms and emotion regulation can be identified in late childhood and middle adolescence and are differentially associated with outcomes related to wellbeing and adaptive functioning in young adulthood. Further, the frequency and quality of co-occurring symptoms evidenced among youth may change over time as reflected in transitions from classes identified in middle childhood to adolescence. Emotion regulation and parenting may be potential targets for enhanced interventions intended to promote subjective wellbeing and adaptive functioning among youth with internalizing and externalizing symptoms. / Psychology

A sizeable proportion of adults suffer from an anxiety disorder and many of those adults are parents. Parental anxiety, as well as dysfunctional family environment, contributes to both internalizing and externalizing problems in children. Specifically, family control, conflict, and cohesion have been shown to predict child internalizing and externalizing symptoms to varying degrees. However, few studies have examined the association between all three components in the same study: parental psychopathology, family environment, and child outcomes. The current study tested the relationships among these variables in a sample of 189 children (66% male, 93% Caucasian, mean age = 10.34 years). Family conflict predicted child externalizing symptoms for both mothers and fathers, and mediated the relationship between maternal anxiety and child externalizing symptoms. Family cohesion predicted child externalizing problems based on maternal report and mediated the relationship between maternal anxiety and child externalizing symptoms. Furthermore, family cohesion moderated the relationship between maternal anxiety and child internalizing symptoms. These findings provide preliminary support for the role of the family environment in the relationship between parental anxiety and child psychopathology, and these environmental variables may be important targets of intervention in families with elevated parental anxiety. / Master of Science

The primary purpose of this research was to examine the long-term relations between peer victimization and internalizing symptoms (anxiety and depression) in middle school children. Furthermore, this study intended to determine the potential roles of self-worth, self-acceptance, and social supports in moderating or mediating these proposed relations. At time one, 280 sixth grade students participated and at follow up, 77 eighth grade children were participants. All children were from the same public middle school and completed self-report measures representing the constructs previously described. Reported levels of peer victimization were found to be similar to those reported in previous studies. Significant concurrent correlations were found between the sixth grade predictor variables (victimization, self-worth, social acceptance, social supports). Sixth grade reported peer victimization was also significantly associated with eighth grade depression for boys and eighth grade social anxiety for girls. Tests of mediation supported the role of global self-worth for boys and social acceptance for girls. Teacher support served a significant moderating role for boys' peer victimization-internalizing symptom (depression and social anxiety) relation. In both cases, boys reported fewer internalizing symptoms when peer victimization was low and teacher support was high. Findings are integrated into the literature regarding peer victimization and internalizing difficulties. / Ph. D.

Current research suggests schools face many barriers in effectively monitoring student's response to behavioral interventions in the classroom. The purpose of this study was to evaluate the FastBridge - Direct Behavior Rating (FastBridge-DBR), a brief, novel progress monitoring measure, designed to assess student behavioral change in response to a classroom behavioral intervention. Twenty-four elementary teacher-student dyads implemented a daily progress report intervention to promote positive student behavior during pre-specified classroom activities. FastBridge-DBR data were then collected for three target behaviors (i.e., Academic Engagement, Disruptive Behavior, Withdrawal) and compared to Systematic Direct Observation (SDO) data. Five change metrics (i.e., absolute change, percent of change from baseline, improvement rate difference, Tau-U, effect size; Gresham, 2005) were used to examine sensitivity to change. The Usage Rating Profile - Assessment (URP-A) was used to evaluate teacher acceptability of FastBridge-DBR. FastBridge-DBR scores were highly correlated with SDO data, demonstrating evidence of concurrent validity. FastBridge-DBR change metrics were significantly correlated with SDO change metrics. Additionally, while teachers provided high acceptability ratings for FastBridge-DBR, there was a lack of association between teachers' ratings of acceptability and student behavioral change. Implications for practice, study limitations, and areas of future research are discussed.

In the last few decades the focus of immigration flows has been predominantly toward member countries of the Organization for Economic Co-operation and Development (OECD). Immigration is a process full of challenges, and perceiving as being discriminated by host country natives is one of the biggest difficulties for the immigrants. This challenge is especially represented in immigrant adolescent population due to their higher sensitivity of perception of others. Thus, perceived discrimination characterized as being a significant negative consequence resulting internalizing mental health outcomes for immigrant adolescents. Therefore, the aim of this study is to conduct a systematic literature review in order to identify and discuss the findings of the existing studies that focus on the consequences of perceived discrimination on internalizing mental health outcomes for immigrant adolescents in OECD countries. The systematic review included 16 studies for data extraction. The results showed that perceived discrimination has significant negative consequences on internalizing mental health outcomes for immigrant adolescents in OEDC countries resulting in higher levels of: depression, anxiety, psycho-somatization, post-traumatic stress disorder, and obsession-compulsion symptoms. However, within this relationship, there are also moderating and mediating variables. Self-esteem, familism and cognitive appraisal of discriminatory events were characterized as mediators. Parental support, adherence to traditional family values, acculturation, transcultural identity, older age, higher socioeconomic status (SES), and ethnic identity were characterized as moderators. It is recommended that the negative consequences of perceived discrimination on internalizing mental health outcomes should be taken into consideration on societal levels and in mental health fields when planning interventions and therapies for immigrant adolescents. Additionally, further research in this field should be conducted in other OECD countries with different immigrant groups in order to increase the generalizability of the findings.

The purpose of the study is to examine young children's internalizing and externalizing behaviors in the context of post paternal incarceration by focusing on both risks (i.e., parental depressive symptoms), protective factors (i.e., coparenting alliance), and their impact considered together. The final sample included 426 previously incarcerated fathers and the biological mothers of their three-year-old children. Using hierarchical multiple regression, I examined three sets of analyses: 1) the association between parental depressive symptoms and children's behavior outcomes, 2) the association between coparenting alliance and children's behavior, 3) the association between parental depressive symptoms and children's behavior as moderated by coparenting alliance. Expectedly, higher paternal depressive symptoms were associated with higher externalizing behavioral problems in children. Unexpectedly, higher maternal depressive symptoms were associated with lower externalizing behavioral problems. Also, unexpectedly, the associations between maternal and paternal coparenting alliance and both child behavioral outcomes were not statistically significant. Further, when mothers reported lower coparenting alliance with their child's father, the negative association between fathers' depressive symptoms and children’s internalizing behavioral problems was not attenuated; in fact, children had higher internalizing behavioral problems. My findings suggests father's depressive symptoms are an important point of consideration given the deleterious effects parental depressive symptoms can have on children, and the risks for depressive symptoms among formerly incarcerated fathers. Further, my findings have implications for addressing and treating fathers' depressive symptoms when children are relatively young in order to lower internalizing behavior problems from persisting across and beyond childhood.
