abstract: Although researchers often conceptualize shyness as stable across different situations (e.g., Rubin, Coplan, & Bowker, 2009), evidence has suggested that shyness may consist of situation-specific components (e.g., Asendorpf, 1990a; 1990b; Gazelle & Faldowski, 2014; Xu & Farver, 2009). This study was aimed at developing a systematic measurement tool for situational shyness in adolescence, as well as examining the relations between situational shyness and other popular measures of shyness and between situational shyness and adjustment. A sample of Chinese adolescents (N = 492) from an urban school participated in the study during 7th (T1) and 8th (T2) grades. Adolescents self-reported their situational shyness using a new measure of hypothetical scenarios, as well as their general shyness, anxious shyness, regulated shyness, depressive symptoms, and loneliness. Peers reported adolescents’ general and conflicted shyness, and popularity and peer rejection. The school provided records of their academic achievement (exam scores). Exploratory and confirmatory factor analyses of the situational shyness measure consistently supported that shyness in the hypothetical scenarios can be separated into three components: shyness with familiar peers, shyness with unfamiliar peers, and shyness in formal situations. These components had differential associations with other measures of shyness. Self-reported general and anxious shyness were related consistently to shyness with unfamiliar peers and in formal situations, and occasionally to shyness with familiar peers. Self-reported regulated shyness was not related to self-reported shyness in any situation. Peer-reported conflicted shyness was associated with shyness with familiar and unfamiliar peers, whereas peer-reported general shyness was associated with shyness with unfamiliar peers and in formal situations. Moreover, situational shyness showed differential relations to maladjustment. Shyness with familiar peers was associated positively with maladjustment in multiple domains, especially academic and peer difficulties. Shyness with unfamiliar peers and shyness in formal situations, in contrast, were associated primarily with internalizing problems. In addition, shyness with unfamiliar peers and in formal situations occasionally related to positive adjustment, suggesting shyness in specific situations may still be protective in contemporary urban China. The findings provided new evidence that the correlates of shyness depend on the situation in which shyness occurs, and may inform future intervention programs. / Dissertation/Thesis / Doctoral Dissertation Family and Human Development 2019

Childhood mental health problems are considered to fall along internalizing and externalizing dimensions; however, this framing does not fully capture the complexity of the relations among these symptoms. Specifically, internalizing problems (Int), conduct problems (CP), and callous/unemotional (CU) behaviors frequently co-occur and may share emotion functioning and contextual correlates that differentially confer risk across these potential symptom profiles. Research is shifting toward testing models of shared vulnerabilities to childhood emotional and behavioral symptoms, but has yet to extensively examine CU behaviors concurrently with these symptoms. The culmination of findings across relevant literature, though sparse, identifies candidate shared child-specific correlates such as emotion function (i.e., recognition, regulation, lability, processing); exposure to community violence; parent emotion socialization practices; and peer processes (e.g., bullying/victimization, social support) as shared correlates of Int, CP, and CU behaviors that may further differentiate profiles that differ in the frequency, type, or severity of symptoms. Such information could facilitate identification of youth at risk for problematic symptoms and outcomes. The current study sought to identify profiles of Int, CP, and CU behaviors in a sample of 104 low-income (69% income < $19,999; all eligible for free school meals) urban youth (M= 9.93 ± 1.22 years old; 50% male; 95% African American). Teachers rated Int, CP, and CU behaviors; and caregivers rated their emotion socialization practices and youth emotion regulation and lability. Youth reported on bullying, peer victimization, social support, and exposure to community violence and completed two lab tasks to assess emotion recognition and processing. A latent profile analysis yielded three teacher-reported profiles: (1) high internalizing, moderate CU, and moderate CP (High-Int/Mod-CU/CP, n = 16; 51.7% male); (2) high generalized anxiety disorder symptoms, CU, and CP (High-GAD/CU/CP, n = 16; 80.9% male); and (3) low problematic behaviors (Low, n = 59; 45.5% male), with the first two profiles rated as having co-occurring presentations of anxiety, depression, and CU behaviors, with different levels of CP. Auxiliary analyses revealed that the High-Int/Mod-CU/CP and High-GAD/CU/CP profiles differed only in levels of recognition of sad facial expressions, whereas the High-GAD/CU/CP and Low profiles differed on witnessing community violence and emotion regulation. The High-GAD/CU/CP profile also reportedly exhibited the greatest engagement in bullying and emotional lability. Current findings add to the growing literature on profiles of youth emotional and behavioral problems that include different constellations with co-occurring CU behaviors among youth in contexts that place them at increased risk for poor functional outcomes. / Psychology

Updated: Current version includes the name of Supervisor, and Co-supervisor. Error corrected in preliminary pages. / Background: Emerging evidence suggests that there is both within-disorder heterogeneity and across-disorder overlap in the clinical presentation of children with ASD, ADHD, and OCD. Two prevalent dimensional phenotypes in children with these NDDs that warrant close attention, and are suitable for cross-disorder investigation, are internalizing and externalizing problems. Objectives: The current study uses a data-driven, diagnosis-agnostic approach to identify homogenous clusters that describe behavioural profiles of internalizing and externalizing problems within and across ASD, ADHD, and OCD. Methods: Data on 1565 children (M = 10.76 years) were drawn from the Province of Ontario Neurodevelopmental Disorder (POND) Network. Non-hierarchical clustering approaches were used to empirically derive, distinct behavioural profiles of internalizing and externalizing problems indexed by the Child Behavior Checklist (CBCL). Empirically derived groups were characterized using measures of adaptive functioning indexed by the Adaptive Behaviour Assessment (ABAS-II), and interpreted in relation to original diagnoses. Results: Cluster analyses identified four distinct behavioural profiles that cut across all diagnostic groups: High Internalizing Externalizing (HIE; 15%), High Externalizing (HE; 21%), Low Internalizing Externalizing (LIE; 38%), and Low Externalizing (LE; 26%). Derived clusters had variable levels of adaptive behaviours and reflected different behavioural profiles than the ones defined by the original diagnostic category groups of ASD, ADHD, and OCD. Conclusion: Data-driven, diagnosis-agnostic approaches can inform our understanding of the between and within phenotypic heterogeneity seen in ASD, ADHD, and OCD. Empirical ways of classifying children with homogeneous behavioural profiles may complement existing diagnostic models in our efforts to develop cross-disorder, more personalized interventions for children with neurodevelopmental disorders. / Thesis / Master of Science (MSc) / ASD, ADHD, and OCD are heterogenous neurodevelopmental disorders (NDDs) with some overlapping clinical characteristics and etiological factors. Internalizing and externalizing behavioural problems persist across these three NDDs, and in this study, are used to identify unique behavioural profiles. Study findings reveal four groups with distinct behavioural profiles of internalizing and externalizing problems that are not identified by the original diagnostic groups. This empirical way of classifying children with similar behavioural profiles can be used in combination with diagnostic labels to enhance transdiagnostic interventions that can be tailored to each child’s needs.

The first purpose of this study was to investigate the direct effects of three subtypes of social withdrawal (shyness, social avoidance, and unsociability, respectively) on internalizing outcomes (depression, emotional dysregulation, and self-worth, respectively) in emerging adulthood and to examine these effects by gender. A second purpose was to examine if parenting moderates (i.e., exacerbates or buffers) the main effects of social withdrawal on internalizing outcomes. Participants included 790 undergraduate students from four universities in the United States (Mage = 19.61, SD = 1.85, range = 18–29; 243 males, 547 females) and their mothers. Regression analyses established that shyness was associated with higher levels of depression and emotional dysregulation as well as lower self-worth for males and females. Social avoidance was linked with higher levels of depression and emotional dysregulation for females only. Finally, unsociability was associated with lower levels of depression and dysregulation for both genders. Analyses also established that parenting did not moderate depression, emotional dysregulation, or self-worth with regard to shyness or social avoidance. However, helicopter parenting moderated the links between unsociability and depression. Authoritative parenting moderated the links between unsociability and dysregulation and self-worth. Discussion focuses on the outcomes for emerging adults and the moderating roles of gender and parenting.

The purpose of this study is to examine the effects of cohabitation on children in kindergarten and how this varies by race. Many researchers have shown that children being raised in cohabiting families do not perform as well as children being raised in married parent families (Manning and Seltzer 2009; Artis 2007; Raley et al 2005). Furthermore, demographic trends show that cohabitation among Latinos is very similar to marriage, whereas among whites they are two very different things (Choi and Seltzer 2009). My research combines these two ideas to investigate how cohabitation may affect Latino children differently than it affects white children in terms of internalizing and externalizing behavior problems. I hypothesize that though whites will be negatively affected by cohabitation, Latinos will not have this negative effect. Evidence supports hypotheses and suggests that, indeed, Latino children are not as negatively affected by cohabitation as Whites.

The purpose of this study was to examine marital romantic relational aggression in parents and its impact on adolescent relational aggression, adolescent romantic relational aggression, internalizing, and school engagement with self-regulation as a potential mediator. Gender differences were also examined. Adolescents were from 328 two-parent families in a large north-western city in the United States and were between 12 and 17 years of age (M=14.24, SD=1.00, 51% female) at time 4. All independent variables except adolescent self-regulation were measured at wave 4, and all adolescent variables were measured at wave 5. Results indicate that higher levels of romantic relational aggression from mother to father was directly related to higher relational aggression in girls and lower romantic relational aggression in boys one year later. Father romantic relational aggression was directly and negatively related to romantic relational aggression in girls one year later. Mother romantic relational aggression was indirectly related to all outcomes in females only, in the predicted directions, through adolescent self-regulation. Father romantic relational aggression was indirectly related, in the predicted directions, to relational aggression, internalizing, and school engagement in boys only. Implications for research and clinical practice are discussed.

This study utilized an ecological framework to investigate the types of variables that influence adolescent adjustment during middle school and how influences change or stay the same depending on grade level. A cross-sectional approach was taken in which students entering the beginning of their Sixth Grade year and students nearing the end of their Eighth Grade year were administered a comprehensive questionnaire including items about psychological adjustment, parenting characteristics, community support characteristics, ethnic identity, acculturation status, and socio-economic status. Findings suggest that Sixth and Eighth Graders’ experience of emotional and behavioral problems is influenced differently. This is particularly salient as it pertains to parenting support and acculturation variables. Findings support the notion that individualized, multi-systemic style interventions are valuable even within the developmental period of adolescence as important changes in risk and protective factors are taking place as one moves from early- to mid-adolescence.

Strong Teens is a curriculum designed to help students develop the social-emotional skills needed to manage challenges and become successful socially and academically (Carrizales- Engelmann et al., 2016). Strong Teens has shown promise among adolescents, but this was the first study to evaluate the newly updated version of the intervention in a high school setting. The curriculum was implemented by a special education teacher with students at-risk for emotional and behavioral disorders. A mixed method design was used to evaluate outcomes with 16 ninth grade students. Overall findings suggest that Strong Teens was effective at improving students' social emotional knowledge over a 3-month period. However, there was a worsening of students' internalizing symptoms and teacher-student relationships. The teacher implemented the curriculum with low to moderate fidelity. Students were mostly neutral in their view of Strong Teens, while the teacher held a more favorable view. Future studies should include a larger sample size, offer training to educators on the implementation of Strong Teens, and consider using a more effective collection method to ensure students' anonymity.

Objectives: A meta-analysis was conducted to determine the average effect size of internalizing and externalizing symptoms after pediatric traumatic brain injury across a range of severity (mild, moderate, and severe). Two-meta-regressions were also conducted to determine the role of age at injury at time since injury on these effect sizes.Participants and Methods: 9725 titles and abstracts were collected from PubMed, PsycInfo, and Web of Science. Of these, 63 full-text articles were examined for inclusion criteria to determine eligibility for the study. To be included, the studies needed to be published prior to March 2017 in English, needed to have a control group of either orthopedically injured or typically developing peers, and required a reliable and valuable measure of internalizing and externalizing symptoms in children. Studies were excluded for non-accidental head injuries or if the sample recruited was outside the range of 2-17 years old at the time of injury. The analysis was based on 16 studies including 1083 cases of mild TBI, 184 cases of moderate TBI, 214 cases of severe TBI, and 1605 control cases.Results: Analyses revealed a large effect size for internalizing symptoms of children with mild TBI (Hedges g = -0.624, p = 0.009), a small effect size for moderate TBI (Hedges g = -0.238, p = 0.029), and a large effect size for severe TBI (Hedges g = -0.923, p < .001). These findings indicate that parents rate childrens internalizing symptoms more severely for brain injured children than for typically developing or non-brain injured peers. These children may be experiencing more severe symptoms such as anxiety and depression regardless of injury severity. For externalizing symptoms, analyses demonstrated a moderate effect size for mild TBI (Hedges g = -0.531, p = 0.003), a small effect size for moderate TBI (Hedges g = -0.257, p = 0.007), and a large effect size for severe TBI (Hedges g = -0.909, p < .001). Thus, children who experienced a TBI demonstrated externalizing symptoms including hyperactivity and impulsivity with the largest effect size associated with severe TBI. The results of the meta-regressions indicated that only injury severity was a significant predictor of symptom severity.Conclusions: Using meta-analytic methods, we found that children who experience traumatic brain injury are rated as exhibiting more severe internalizing and externalizing symptoms across levels of severity. This effect was largest for severe injury and smallest for moderate injury. Caregivers and healthcare practitioners can use this information to better screen for and treat internalizing and externalizing symptoms in children after a traumatic brain injury.
