Women's Cognitive Appraisals Of Their Birth Experience As Predictive And Maintaining Factors Of Postpartum Posttraumatic Stress Symptom Severity, Lauren Carr Spooner

Dissertations

Empirical support has accumulated for evidence of posttraumatic stress symptoms following approximately 30% of childbirth experiences (Olde, van der Hart, Kleber, & van Son, 2006). Researchers have suggested that there is a complex relationship among predisposing, precipitating, and maintaining factors that impact postpartum PTSD (Slade, 2006). Anxiety, perception of support, and negative cognitions are such factors that have been shown to significantly correlate with PTSD symptoms (Foa & Rothbaum, 1998; Olde et al., 2006; Soet, Brack, & Dilorio, 2003), but have not been studied together in relation to PTSD associated with traumatic birth. The current study controlled for trait anxiety …

A Comparison Of The Effects Of A Function-Based Intervention To A Non-Function-Based Intervention To Address Problem Behaviors In Preschoolers, Katherine Marie Bellone

Master's Theses

Problem behaviors occur frequently among preschool children in classrooms, impeding academic development. Past methods employed for development of behavioral interventions include functional assessment and use of evidence-based practices. The current investigation sought to empirically compare the effectiveness of both function-based and non-function-based interventions to increase appropriate engagement and decrease occurrence of problem behaviors. Participants included three preschool children, two attending pre-kindergarten classrooms at an elementary school and one at a Head Start Center. Differential reinforcement of alternative behavior was used as the function-based intervention and was compared to a token economy intervention in an Alternating Treatments Design. Results indicated that …

The Effects Of Check In/Check Out On Levels Of Problem Behavior And Academic Engagement In Elementary School Students, Leila Mullooly Miller

Master's Theses

Previous studies have largely evaluated the effects of check in/ check out (CICO) using office discipline referrals (ODRs). However, ODRs are not always reliable measures of student behavior, and direct observation is known to be an accurate tool for behavioral measurement. Due to this, the current study used direct observations to evaluate the effects of CICO on levels of problem behavior and academic engagement for a group of elementary school students. One second, one fourth, and one sixth grade student served as participants. Results indicate CICO is effective in decreasing problem behavior and increasing academic engagement. Data from teacher ratings …

Lead And Attention-Deficit/Hyperactivity Disorder: A Meta-Analysis, James Kenneth Goodlad Iii

Master's Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is thought to have a significant neurological component, and several brain structures have been implicated. Environmental variables like lead have been shown to affect brain structures, which in turn impacts cognitive development and behavior. Some studies have begun to associate environmental variables like lead with the inattentive and hyperactive-impulsive symptoms of ADHD. This meta-analysis examined the association between different components of ADHD (including attention problems and hyperactivity/impulsivity) and level of lead exposure in children and adolescents. Articles focusing on the association between lead and inattention or hyperactivity-impulsivity symptoms were gathered from the online databases PsycINFO and Medline. …

A Meta-Analysis Of Component Treatment Studies: Are The Parts As Good As The Whole?, Erin Jane Clarke

Master's Theses

Psychotherapy has been proven effective in treating a variety of mental health issues. However, there is disagreement in psychotherapy research about whether or not factors common to all psychotherapies or specific ingredients within a treatment package are responsible for successful treatment outcomes. Component studies are research designs specifically aimed at identifying the mechanisms of change in a full treatment package. Component studies do this by comparing the differences in outcome among dismantled treatment components and the full treatment protocol. The present metaanalytic review of component studies examined whether or not differences between these two treatment groups generally exist. Fifty-nine component …

The Family Environment And Children With An Autism Spectrum Disorder: A Longitudinal Examination Of The Relation Between Parental Expressed Emotion And Child Externalizing Behaviors, Stephanie Bader

Dissertations

The current study, a longitudinal study using Bader (2009) as Time 1 data, used questionnaire data to explore the longitudinal relation between parental expressed emotion, a well-established predictor of symptom relapse in various other disorders (e.g., schizophrenia, bipolar, and behavior disorders), with change in externalizing behaviors in 84 children, ages 8 to 18, with an autism spectrum disorder (ASD). Both components of expressed emotion, criticism/hostility and overinvolvement, were explored, though hypotheses were only made in regard to criticism/hostility. It was found that high levels of parental criticism/hostility, not parental overinvolvement, at Time 2 uniquely related to higher levels of externalizing …

A Moderational Model Investigating Child Temperament, Executive Functioning, And Contextual Predictors Of Externalizing Behaviors In Preschoolers, Ferne Arlene Pinard

Dissertations

Child externalizing behavioral problems (e.g., ADHD symptoms and aggressive behaviors) often appear early in life, are relatively stable, and are associated with maladaptive outcomes in many domains of functioning. Research has shown that, for a subset of children who demonstrate these early behavioral patterns, the course is often more pervasive and persistent. Consequently, a better understanding of externalizing behavioral problems during the preschool period is essential. The current study examined whether biologically-based correlates (i.e., child temperament and executive functioning/neurocognitive attention; EF/Attention) would moderate the relation between the contextual correlates (i.e., socioeconomic status and parenting practices) and externalizing behaviors (i.e., ADHD …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury

Dissertations

Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …

An Electrophysiological Examination Of Adhd-Associated Symptoms And Selective Attention In Adults, Erica Diane Prentkowski

Dissertations

A main component of Attention-Deficit/Hyperactivity Disorder (ADHD) is a deficit of inattention. This deficit causes impairment for both children and adults in a variety of settings including school and work. The current study examined auditory selective attention in a community sample of adults. It was the aim of this project to examine possible differences in selective attention for adults with high levels of ADHDassociated symptoms, when compared to adults with low levels of ADHD-associated symptoms, including conditions under which these differences may be an advantage. Specifically, it was expected that adults with high ADHD-associated symptoms would benefit from the high …

Parenting A Chronically Ill Child: Social Support, Coping, Family Hardiness, And Maternal Stress, Kathryn Lynch Bigalke

Master's Theses

Parents of children with cancer experience higher stress than parents of children with other medical conditions or with no developmental concerns (Canam, 1993; Cohen, 1999). Researchers are beginning to explore a number of protective factors that may influence parental stress in parents of children with cancer. Social support (Abidin, 1992), problem-focused coping (Judge, 1998), and family hardiness (Maddi et al., 2006) have been related to lower levels of stress and more positive outcomes in parents of healthy children, but have not been fully explored in the pediatric cancer population. The current study was designed to assess the relationship between parental …

The Relationship Of Testosterone And 5-Ht To Aggressive, Self-Aggressive, And Antisocial Behavior In Men, Anne Winston Mcintyre

Master's Theses

Studies of humans show an inconsistent relationship between aggression and T, as well as between T and antisocial and self-aggressive behavior. Other biological variables, including cortisol and brain serotonin, have been implicated as having an effect on the regulation of antisocial and self-aggressive behavior. Researchers have suggested that inconsistencies in the T-aggression relation may be due to the presence of moderating variables. One theory posits that serotonin moderates the relation between T and aggression. The purpose of this study was to examine the relationship between T (as well as cortisol and 5-HT) and aggression-related constructs. A second purpose was to …

Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms

Master's Theses

Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …

The Relation Between Externalizing Behaviors Of Children With An Autism Spectrum Disorder And The Externalizing Behaviors, Internalizing Symptoms, And Social Problems Of Their Typically-Developing Siblings, Theodore S. Tomeny

Master's Theses

Existing literature regarding the maladjustment of siblings of children with an autism spectrum disorder (ASD) remains inconclusive. Some studies suggest that difficulties associated with having a child with an ASD in the family result in an adverse experience for both parents and siblings. Dissent within. the literature suggests that certain factors, both environmental and genetic, must be present for maladjustment to occur in typically-developing siblings. Parents of a child with an ASD and a typicallydeveloping sibling (ASD group) and parents of two typically-developing siblings (Control group) provided data via online questionnaires. Both diagnostic category and autism symptoms severity were tested …

An Exploratory Investigation On The Effects Of An Electronic Recording System For Repeated Reading, Seajae Calvin Hartness

Dissertations

Repeated Reading is a common reading intervention that has been used to help students read fluently since 1979. There are many variations of Repeated Reading that have been investigated and found to be effective. However, there is a relative research deficit on the effectiveness of software programs for administering Repeated Reading. This exploratory research project examined the effectiveness of Repeated Reading with an electronic recording system. The performance of the electronic Repeated Reading group was compared to the performance of participants who received traditionally administered Early Intervention Program services. The results suggest that electronically scored Repeated Reading is as effective …

The Structure Of Equine Personality, Rachel Etta Kristiansen

Dissertations

The current study was designed to investigate the structure of equine personality. Two personality questionnaires were replicated from previous studies and implemented simultaneously to test the theory that different questionnaires may extract different personality structures. Breed and sex differences were also hypothesized to be significantly different for some personality dimensions. A total of 827 horses were rated on a 90-item personality questionnaire. Participants were recruited online via email and completed the survey at their own convenience. An additional 121 respondents rated a horse that had already been rated; these results were used to calculate inter-rater reliability.

After data collection was …

The Effects Of Facial Expression On Out-Group Discrimination, Charles Brendan Clark

Dissertations

The current paper sought to test the hypothesis that the facial expression of smiling would mitigate the effects of out-group discrimination. Study 1 examined the influence of facial expression (smiling or frowning), gender (man or woman), and race (Black or White) on resource allocation decisions. Participants were shown arrays of facial photographs. The arrays all contained eight photographs and were counterbalanced to contain all combinations of the variables of interest (i.e., each group had a smiling man of each race, a smiling woman of each race, a frowning man of each race, and a frowning woman of each race). The …

Evaluating Parenting Practices As A Mediating Factor Between Marital Conflict And Children's Adjustment, Kristin Lee Tyson

Master's Theses

A wealth of research has illustrated that negative parenting practices mediate the relation between destructive marital conflict and externalizing problems in children; however, the study of constructive marital conflict and adjustment problems in children is less developed. Research has also suggested that psychological control is related to children's behavior; however, previous research is unclear as to the specific relationship between marital conflict and children's internalizing and externalizing behavior. To address this gap, the present study examined positive and negative parenting practices and psychological control as mediators of constructive and destructive marital conflict and children's internalizing and externalizing problems. Married mothers …

The Role Of Hardiness In Moderating Parenting Stress In Iraq And Afghanistan War Veterans, Victoria Jane Tomassetti-Long

Master's Theses

There is a link between parenting stress and negative child outcomes. Research has focused on a number of risk and protective factors that may influence parental practices and child behavior. Parental trauma has been identified as a risk factor for increased parental stress. Previous research has demonstrated a link between combat exposure and parenting stress in veterans of war. Hardiness, a personality variable that describes an individual's sense of commitment, control, and challenge in light of life stress, has been identified as a protective factor that buffers against the development of psychological symptoms in combat veterans. The current study assessed …
