The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan Jan 2020

The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan

Theses and Dissertations

Background: Postpartum depression (PPD) is a phenomenon that affects nearly 10-15% of pregnancies in the US. It is characterized by depressed mood or anhedonia and lasting for more than 2 weeks. PPD changes how moms interact with family members and child-rearing behavior. Depression is a phenomenon that is also known to affect the psychopathology of children. However, the specifics of how postpartum depression impacts children remains controversial. Many studies do not control for major depressive disorder which makes it difficult to disentangle the impact depression has within the first year of life. Furthermore, other PPD risk factors may be confounding …

Altered Brain Functional Connectivity Varies By Form Of Craniosynostosis, Alexander Haosi Sun Jan 2018

Altered Brain Functional Connectivity Varies By Form Of Craniosynostosis, Alexander Haosi Sun

Yale Medicine Thesis Digital Library

This study uses functional MRI (fMRI) to study long-term neurocognitive sequelae of nonsyndromic craniosynostosis (NSC), and understand if these aberrations vary by form of synostosis. Twenty adolescent participants with treated NSC (10 sagittal (SSO), 5 right unilateral coronal (UCS), 5 metopic (MSO)) were matched to controls by age, gender, and handedness. A subgroup of MSO was classified as severe metopic synostosis (SMS) based on the endocranial bifrontal angle. Resting-state fMRI was acquired in a 3T Siemens TIM Trio scanner, and data was motion- corrected, cluster-corrected with nonparametric permutation tests, and analyzed with BioImage Suite. SSO had decreased intrinsic connectivity compared …

Searching For A Common Thread: A Retrospective Chart Review Of Child And Adolescent Restraints And Seclusions, Mary Koziura Apr 2016

Searching For A Common Thread: A Retrospective Chart Review Of Child And Adolescent Restraints And Seclusions, Mary Koziura

DNP Scholarly Projects

Child and Adolescent psychiatry is an increasingly frequented area of research. The project leader believes violence in an inpatient psychiatry setting is an underrepresented topic of research and discussion. Close quarters among patients of varying diagnoses and backgrounds, coupled with varying culture and attitudes of staff make for a teetering point—a fine line—between therapeutic interaction and safety concerns. Particularly, in the case of patients under 18, one hopes to establish an environment of nurturing, as opposed to a police state. With the fact established that children and their parents should always come first, many of the staff are often exposed …

39. Young Children’S Difficulty With Indirect Speech Acts: Implications For Questioning Child Witnesses, Angela D. Evans, Stacia N. Stolzenberg, Kang Lee, Thomas D. Lyon Oct 2014

39. Young Children’S Difficulty With Indirect Speech Acts: Implications For Questioning Child Witnesses, Angela D. Evans, Stacia N. Stolzenberg, Kang Lee, Thomas D. Lyon

Thomas D. Lyon

Prior research suggests that infelicitous choice of questions can significantly underestimate children’s actual abilities, independently of suggestiveness. One possibly difficult question type is indirect speech acts such as “Do you know…” questions (DYK, e.g., “Do you know where it happened?”). These questions directly ask if respondents know, while indirectly asking what respondents know. If respondents answer “yes,” but fail to elaborate, they are either ignoring or failing to recognize the indirect question (known as pragmatic failure). Two studies examined the effect of indirect speech acts on maltreated and non-maltreated 2- to 7-year-olds’ post-event interview responses. Children were read a story …

28. Right And Righteous: Children's Incipient Understanding Of True And False Statements, Thomas D. Lyon, Jodi A. Quas, Nathalie Carrick Dec 2012

28. Right And Righteous: Children's Incipient Understanding Of True And False Statements, Thomas D. Lyon, Jodi A. Quas, Nathalie Carrick

Thomas D. Lyon

Two studies examined young children's early understanding and evaluation of truth-telling and lying, and the role that factuality plays in their judgments. Study 1 (104 2- to 5-year-olds) found that even the youngest children reliably accepted true statements and rejected false statements, and that older children's ability to label true and false statements as "truth" and "lie" emerged in tandem with their positive evaluation of true statements and "truth" and their negative evaluation of false statements and "lie." The findings suggest that children's early preference for factuality develops into a conception of "truth" and "lie" that is linked both to …

8. Child Witnesses And The Confrontation Clause., Thomas D. Lyon, Julia A. Dente Apr 2012

8. Child Witnesses And The Confrontation Clause., Thomas D. Lyon, Julia A. Dente

Thomas D. Lyon

After the Supreme Court’s ruling in Crawford v. Washington that a criminal defendant’s right to confront the witnesses against him is violated by the admission of testimonial hearsay that has not been cross-examined, lower courts have overturned convictions in which hearsay from children was admitted after child witnesses were either unwilling or unable to testify. A review of social scientific evidence regarding the dynamics of child sexual abuse suggests a means for facilitating the fair receipt of children’s evidence. Courts should hold that defendants have forfeited their confrontation rights if they exploited a child’s vulnerabilities such that they could reasonably …

26. “How Did You Feel?”: Increasing Child Sexual Abuse Witnesses’ Production Of Evaluative Information., Thomas D. Lyon, Nicholas Scurich, Karen Choi, Sally Handmaker, Rebecca Blank Dec 2011

26. “How Did You Feel?”: Increasing Child Sexual Abuse Witnesses’ Production Of Evaluative Information., Thomas D. Lyon, Nicholas Scurich, Karen Choi, Sally Handmaker, Rebecca Blank

Thomas D. Lyon

In child sexual abuse cases, the victim’s testimony is essential, because the victim and the perpetrator tend to be the only eyewitnesses to the crime. A potentially important component of an abuse report is the child’s subjective reactions to the abuse. Attorneys may ask suggestive questions or avoid questioning children about their reactions, assuming that children, given their immaturity and reluctance, are incapable of articulation. We hypothesized that How questions referencing reactions to abuse (e.g., “howdid you feel”) would increase the productivity of children’s descriptions of abuse reactions. Two studiescompared the extent to which children provided evaluative content, defined as …

25. Maltreated Children’S Ability To Estimate Temporal Location And Numerosity Of Placement Changes And Court Visits., Lindsay Wandrey, Thomas D. Lyon, Jodi A. Quas, William J. Friedman Sep 2011

25. Maltreated Children’S Ability To Estimate Temporal Location And Numerosity Of Placement Changes And Court Visits., Lindsay Wandrey, Thomas D. Lyon, Jodi A. Quas, William J. Friedman

Thomas D. Lyon

Research examining children’s temporal knowledge has tended to utilize brief temporal intervals and singular, neutral events, and is not readily generalizable to legal settings in which maltreated children are asked temporal questions about salient, repeated abuse that often occurred in the distant past. To understand how well maltreated children can describe temporal location and numerosity of documented, personal experiences, we assessed 167 6- to 10-year-old maltreated children’s temporal memory for changes in their living arrangements and prior visits to court. Small percentages of children were capable of providing exact temporal location information (age, month, or season) regarding their first or …

24. Interviewing Children Versus Tossing Coins: Accurately Assessing The Diagnosticity Of Children’S Disclosures Of Abuse., Thomas D. Lyon, Elizabeth C. Ahern, Nicholas Scurich

Thomas D. Lyon

We describe a Bayesian approach to evaluating children’s abuse disclosures and review research demonstrating that children’s disclosure of genital touch can be highly probative of sexual abuse, with the probative value depending on disclosure spontaneity and children’s age. We discuss how some commentators understate the probative value of children’s disclosures by: confusing the probability of abuse given disclosure with the probability of disclosure given abuse, assuming that children formally questioned about sexual abuse have a low prior probability of sexual abuse, misstating the probative value of abuse disclosure, and confusing the distinction between disclosure and nondisclosure with the dstinction between …

An Examination Of The Combined Influences Of Maternal Cognitions, Affect, And Behavior On Child Outcomes: A Model Comparison Approach, Elizabeth A. Heideman Jul 2011

An Examination Of The Combined Influences Of Maternal Cognitions, Affect, And Behavior On Child Outcomes: A Model Comparison Approach, Elizabeth A. Heideman

Dissertations (1934 -)

The primary goal of this study was to better understand the combined influence of maternal affect, cognitions and behavior on child internalizing and externalizing behavior. Specifically, mothers and children completed a series of measures designed to assess parenting stress, parenting efficacy, parenting behavior, and child internalizing and externalizing behavior. Participants were 115 mothers and their school-aged children who participated in an outpatient neuropsychological evaluation. Results suggest that child reported maternal warmth and control were important in influencing the development of internalizing behavior in children. Additionally, maternal parenting stress, warmth and control were found to be important influences in the development …

Children's Understanding Of Intimate Partner Violence, Renee Lynn Deboard-Lucas Jul 2011

Children's Understanding Of Intimate Partner Violence, Renee Lynn Deboard-Lucas

Dissertations (1934 -)

There is a clear connection between exposure to interparental aggression and children's own future episodes of violent behavior. What is significantly less understood is why this pattern develops. The current study used quantitative and semi-structured methods to identify factors that shape children's understanding of intimate partner violence. Understanding violence was defined as including causal knowledge (Why does violence occur?) and beliefs about the acceptability of intimate partner violence. Factors proposed to predict children's causal attributions included mothers' perceived causes of interparental aggression and exposure to different forms of violence, including interparental, parent-child, and neighborhood aggression. Perceived causes of intimate partner …

15. Assessing The Competency Of Child Witnesses: Best Practice Informed By Psychology And Law., Thomas D. Lyon Jun 2011

15. Assessing The Competency Of Child Witnesses: Best Practice Informed By Psychology And Law., Thomas D. Lyon

Thomas D. Lyon

Truth-lie competency, which concerns the child's understanding of the difference between truth and lies and the importance of telling the truth, can be demonstrated by asking the child whether simple statements are the truth, and by asking the child to promise to tell the truth. Tests of children's truth-lie competency do not predict honesty, but eliciting a child's promise to tell the truth does increase honesty.

23. Assessing Children’S Competency To Take The Oath In Court: The Influence Of Question Type On Children’S Accuracy., Angela D. Evans, Thomas D. Lyon

Thomas D. Lyon

This study examined children’s accuracy in response to truth–lie competency questions asked in court.The participants included 164 child witnesses in criminal child sexual abuse cases tried in Los AngelesCounty over a 5-year period (1997–2001) and 154 child witnesses quoted in the U.S. state and federalappellate cases over a 35-year period (1974 –2008). The results revealed that judges virtually never foundchildren incompetent to testify, but children exhibited substantial variability in their performance based on question-type. Definition questions, about the meaning of the truth and lies, were the most difficultlargely due to errors in response to “Do you know” questions. Questions about …

22. Young Children’S Emerging Ability To Make False Statements., Thomas D. Lyon, Elizabeth C. Ahern, Jodi A. Quas

Thomas D. Lyon

This study examined the origins of children’s ability to make consciously false statements, a necessary component of lying. Children 2 to 5 years of age were rewarded for claiming that they saw a picture of a bird when viewing pictures of fish. They were asked outcome questions (“Do you win/lose?”), recognition questions (“Do you have a bird/fish?”), and recall questions (“What do you have?”), which were hypothesized to vary in difficulty depending on the need for consciousness of falsity (less for outcome questions) and self-generation of an appropriate response (more for recall questions). The youngest children (21⁄2 to 31⁄2 years …

14. Investigative Interviewing Of The Child., Thomas D. Lyon

Thomas D. Lyon

Children, if questioned in a supportive manner, are capable of providing enormous amounts of productive information in response to open-ended questions. The irony is that many direct and suggestive methods once thought necessary to overcome abused children's reluctance to disclose abuse have been found counterproductive in two ways: they minimize the number of details in true allegations at the same time that they increase the risk of false allegations.

20. Maltreated And Non-Maltreated Children’S Evaluations Of Emotional Fantasy., Nathalie Carrick, Thomas D. Lyon, Jodi A. Quas

Thomas D. Lyon


Objectives: The purpose of the study was to examine differences between maltreated and nonmaltreated children’s ability to differentiate emotionally evocative fantastic and real events.
Methods: Four- and 5-year-old (n = 145) maltreated and nonmaltreated children viewed images depicting positive and negative fantastic and real events and reported whether the events could occur in real life and how the images made them feel. Children also completed a measure of verbal ability.
Results: Maltreated children were more accurate than nonmaltreated children in stating that negative real events could occur, but less accurate in stating that frightening fantastic events …

Best Practices For Increasing Pro-Social Behavior In Adolescents With Mental Health And Behavioral Disorders, Danielle Armbrust-Malone Jan 2009

Best Practices For Increasing Pro-Social Behavior In Adolescents With Mental Health And Behavioral Disorders, Danielle Armbrust-Malone

All Graduate Theses, Dissertations, and Other Capstone Projects

Approximately 2 to 16 percent of the general population has a disruptive behavior disorder such as oppositional defiant disorder (ODD) or conduct disorder (CD) (Corcoran & Walsh, 2006). In a school setting, youth with these disorders may engage in acts such as disrespecting teachers, swearing at others, threatening others, assaulting staff or students, stealing, or vandalizing property and may benefit from a day treatment program which provides mental health services in a school setting. (Whitfield, 1999). Micro intervention strategies such as cognitive behavioral therapy and contingency management and mezzo interventions such as family therapy have been used to treat disruptive …

Developing Evidenced Based Practice For Social Emotional Screenings In Schools, Kim Anderson Jan 2009

Developing Evidenced Based Practice For Social Emotional Screenings In Schools, Kim Anderson

All Graduate Theses, Dissertations, and Other Capstone Projects

The social problem being addressed through this project includes several challenges faced by our nation's schools, namely increasing numbers of disciplinary referrals, suspensions, and expulsions (Marchant, Anderson, Caldarella, Fisher, Young,Young, 2009). Further research states that "more and more children entering school are unprepared to learn, unable to cope with the social tasks involved in making friends and getting along with others, and unaware of their negative social effect on others," (Marchant et al., 2009, p.131). Only about 20% of children and adolescents with a psychiatric disorder in the United States receive any kind of mental health services (Fritz, 2007). Yet …

19. Young Children’S Competency To Take The Oath: Effects Of Task, Maltreatment, And Age., Thomas D. Lyon, Nathalie Carrick, Jodi A. Quas

Thomas D. Lyon

This study examined maltreated and non-maltreated children’s (N = 183) emerging understanding of ‘‘truth’’ and ‘‘lie,’’ terms about which they are quizzed to qualify as competent to testify. Four- to six-year-old children were asked to accept or reject true and false (T/F) statements, label T/F statements as the ‘‘truth’’ or ‘‘a lie,’’ label T/F statements as ‘‘good’’ or ‘‘bad,’’ and label ‘‘truth’’ and ‘‘lie’’ as ‘‘good’’ or ‘‘bad.’’ The youngest children were at ceiling in accepting/rejecting T/F statements. The labeling tasks revealed improvement with age and children performed similarly across the tasks. Most children were better able to evaluate ‘‘truth’’ …

Self-Esteem: The Influence Of Parenting Styles, Jean Wolff Jan 2000

Self-Esteem: The Influence Of Parenting Styles, Jean Wolff

Theses: Doctorates and Masters

This study examines parent/child relationships and their possible influence on self-esteem. The parenting styles: authoritative, authoritarian, permissive and unmatched, are assessed (by child report) and compared to levels of global and specific domains of self-esteem to determine whether parenting style influences self-esteem in children. Eighty-four children aged 11-12 years of age; male and female were asked to complete three questionnaires. The questionnaires were: Child Report of Parental Behaviour Inventory (Schluderman & Schluderman, 1970) to ascertain their parent's parenting style; Harter's (1985), Self-Perception Profile for Children (SPPC), to measure the child's self-esteem and a demographic questionnaire. ANOVA and ANCOVA were used …
