12. Interviewing Victims And Suspected Victims Who Are Reluctant To Talk., Irit Irit Hershkowitz, Michael E. Lamb, Thomas D. Lyon Nov 2013

12. Interviewing Victims And Suspected Victims Who Are Reluctant To Talk., Irit Irit Hershkowitz, Michael E. Lamb, Thomas D. Lyon

Thomas D. Lyon

Most professionals know that many alleged victims do not disclose abuse when formally interviewed and that disclosure is affected by a variety of factors, among which the relationship between suspects and children appears to be especially important (see Pipe, Lamb, Orbach, & Cederborg, 2007, for reviews). Children––especially boys and preschoolers––are hesitant to report abuse by parents and guardians, particularly when sexual rather than physical abuse is suspected. For example, Pipe, Lamb, Orbach, Stewart, Sternberg, and Esplin (2007) reported that only 38% of the preschoolers interviewed disclosed sexual abuse by a parent even when the allegations were independently substantiated by corroborative …

32. Eliciting Maltreated And Non-Maltreated Children’S Transgression Disclosures: Narrative Practice Rapport Building And A Putative Confession., Thomas D. Lyon, Lindsay Wandrey, Elizabeth C. Ahern, Robyn Licht, Megan P.Y. Sim, Jodi A. Quas Oct 2013

32. Eliciting Maltreated And Non-Maltreated Children’S Transgression Disclosures: Narrative Practice Rapport Building And A Putative Confession., Thomas D. Lyon, Lindsay Wandrey, Elizabeth C. Ahern, Robyn Licht, Megan P.Y. Sim, Jodi A. Quas

Thomas D. Lyon

This study tested the effects of narrative practice rapport building (asking open-ended questions about a neutral event) and a putative confession (telling the child an adult “told me everything that happened and he wants you to tell the truth”) on 4- to 9-year-old maltreated and nonmaltreated children’s reports of an interaction with a stranger who asked them to keep toy breakage a secret (n = 264). Only one third of children who received no interview manipulations disclosed breakage; in response to a putative confession, one half disclosed. Narrative practice rapport building did not affect the likelihood of disclosure. Maltreated children …

31. How Attorneys Question Children About The Dynamics Of Sexual Abuse And Disclosure In Criminal Trials., Stacia N. Stolzenberg, Thomas D. Lyon Sep 2013

31. How Attorneys Question Children About The Dynamics Of Sexual Abuse And Disclosure In Criminal Trials., Stacia N. Stolzenberg, Thomas D. Lyon

Thomas D. Lyon

Little is known about how the dynamics of sexual abuse and disclosure are discussed in criminal court. We examined how attorneys ask child witnesses in sexual abuse cases (N #1; 72, 6–16 years of age) about their prior conversations, both with suspects and with disclosure recipients. Prosecutors’ questions were more open-ended than defense attorneys, but most questions asked by either attorney were yes/no questions, and children tended to provide unelaborated responses. Prosecutors were more inclined to ask about children’s prior conversations with suspects than defense attorneys, but focused on the immediate abuse rather than on grooming behavior or attempts to …

29. Young Children’S Understanding That Promising Guarantees Performance: The Effects Of Age And Maltreatment., Thomas D. Lyon, Angela D. Evans Jul 2013

29. Young Children’S Understanding That Promising Guarantees Performance: The Effects Of Age And Maltreatment., Thomas D. Lyon, Angela D. Evans

Thomas D. Lyon

Two studies, with 102 nonmaltreated 3- to 6-year-old children and 96 maltreated 4- to 7-year-old children, examined children’s understanding of the relative strengths of “I promise,” “I will,” “I might,” and “I won’t,” to determine the most age-appropriate means of eliciting a promise to tell the truth from child witnesses. Children played a game in which they chose which of 2 boxes would contain a toy after hearing story characters make conflicting statements about their intent to place a toy in each box (e.g., one character said “I will put a toy in my box” and the other character said …

16. Child Witnesses And Imagination: Lying, Hypothetical Reasoning, And Referential Ambiguity., Thomas D. Lyon Jul 2013

16. Child Witnesses And Imagination: Lying, Hypothetical Reasoning, And Referential Ambiguity., Thomas D. Lyon

Thomas D. Lyon

Children's resistance to unpleasant hypotheticals undermines their apparent understanding of the truth and lies. Better understanding of children's developmental limitations, improved questioning, and objections to developmentally insensitive questions could improve children's performance.

The Moderating Effect Of Skin Conductance Level On The Relationship Between Family Conflict And Disordered Eating Behaviors, Laura B. Kenneally May 2013

The Moderating Effect Of Skin Conductance Level On The Relationship Between Family Conflict And Disordered Eating Behaviors, Laura B. Kenneally

Psychology

The purpose of this study was to examine the moderating effect of the sympathetic nervous system (SNS) on the relation between family conflict and disordered eating behaviors. Participants were 67 undergraduate students at the University at Albany, SUNY, ages 17 to 40. Researchers used a retrospective measure of harsh parenting and interparental aggression experienced during childhood and adolescence to determine how sympathetic activation interacts with family conflict in predicting disordered eating behaviors in a sample of university students. SNS activation was measured by baseline skin conductance level (SCL). Results indicated that SCL moderated the relationship between harsh parenting experienced during …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold May 2013

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …

Resilience And Trauma In Maltreated Youth, Timothy Day May 2013

Resilience And Trauma In Maltreated Youth, Timothy Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research into resilience represents a theoretical shift from the medical model in contemporary psychology to a focus on adaptation (Poulou, 2007). The relationship however between resilience and the development and PTSD in children remains unclear. The purpose of this present study is to expand on this research by investigating resilience and adaptability with respect to Posttraumatic Stress Disorder (PTSD) symptoms across maltreated youth of different ethnicities at risk for PTSD. Participants will be recruited from a Department of Family Services (DFS)-affiliated clinic in the Las Vegas area and administered the Children's PTSD Inventory (CPTSD-I), Behavior Assessment System for Children-2 Parent …

An Empirically-Supported Model Of Posttraumatic Stress Disorder In Maltreated Youth, Adrianna Wechsler May 2013

An Empirically-Supported Model Of Posttraumatic Stress Disorder In Maltreated Youth, Adrianna Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder in maltreated youth is a young and burgeoning field. Lemos-Miller and Kearney (2006) were among the first to propose and test a theoretically and empirically-based model of PTSD in maltreated youth. The present study replicated and evaluated the Lemos-Miller and Kearney model within a larger and more diverse sample of maltreated adolescents. First, the Lemos-Miller and Kearney model was tested via structural equation modeling (SEM). Second, the model was evaluated across age, gender, and ethnicity. Third, trauma history, family environment (i.e., cohesion and conflict), dissociation, and trauma-related cognitions were evaluated as potential mediating variables within the model. …

Analysis Of The Scale Of Parenting And Life Functioning Using The Rasch Measurement Model, Laricia Longworth-Reed Jan 2013

Analysis Of The Scale Of Parenting And Life Functioning Using The Rasch Measurement Model, Laricia Longworth-Reed

Electronic Theses and Dissertations

The purpose of the current study was to examine dimensionality, reliability, invariance, targeting, scale use and functioning of items across subgroups for a sample of 278 on the Scale of Parenting and Life Functioning (SPLF). Analysis was conducted using a Rasch partial credit model. Overall, the SPLF showed good overall fit to the model. Unidimensionality of the scale was supported in the analysis, with over 60% of the raw variance explained by the measure. Item fit also provided evidence that the items fit the model. Scale categories displayed clear monotonicity. No differential item functioning was found for mother's age, race/ethnicity, …

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 …
