The difficulty of distinguishing between genuine disorder and characteristics that can be attributed to high IQ increases the likelihood of diagnostic error by mental health practitioners. This mixed methods study explores the possibility of misdiagnosis of high IQ youth by mental health professionals. Participants were private practice mental health professionals who read case study vignettes illustrating high IQ youth exhibiting characteristics associated with their population. Participants then completed a survey and provided an assessment of the hypothetical client. In the study, 59% of participants were unable to recognize behavioral characteristics associated with high IQ youth unless suggested to them, and 95% of participants were unable to recognize emotional characteristics associated with high IQ youth unless suggested. The results of this study provide much-needed empirical exploration of the concern for misdiagnosis of high IQ youth and inform clinical practice and education.

Considerable psycho-physiological research on empathy examines biological structures such as the hypothalamic-pituitary-adrenal axis (HPA-axis) and oxytocin systems as efficacious methods for strengthening positive emotional responses. This study recruited 76 adult participants (54 female, 23 male) for the purpose of evaluating the effects oxytocin and fiction reading have on empathetic responses. Participants completed a measure of trauma and received either intranasal oxytocin, a story created to induce emotional responses, or a neutral non-fiction story. Stressors were counterbalanced as a family or non-family stimuli to assess changes in stress response measured by salivary cortisol and heart rate variability. Results supported existing research stating that heart rate variability (HRV) is a more sensitive measure of stress. HRV statistically significantly interacted between type of stressor and PTSD symptomology (1, 70) = 5.018, p = .028, η2 =0.06. Scores on the Interpersonal Reactivity Index (IRI) indicated there were increases in empathy across time, but were not impacted by exposure to stress or treatment condition. Trauma was identified as a statistically significant factor on heart rate variability F(1, 70) = 8.39, p = .005, η2 = .10. Treatment condition did not impact cortisol levels across time F(2, 71) = .2.532, p = .087, η2 = .11. …

This study analyzes senior women faculty's discourses about personal and professional experiences they believe contributed to their advancement in academic careers in science, technology, engineering, and mathematics (STEM). The purpose of the study is to understand factors that activate women's success in STEM disciplines where women's representation has not yet attained critical mass. A poststructuralist emphasis on complexity and changing nature of power relations offers a framework that illuminates the ways in which elite women navigate social inequalities, hierarchies of power, and non-democratic practices. Feminist poststructural discourse analysis (FPDA) methods allow analysis of women's talk about their experiences in order to understand the women's complex, shifting positions. Eight female tenured full professors of STEM at research-focused universities in the United States participated in the study. Data sources were in-depth semi-structured interviews, a demographic survey, and curricula vitae. Findings will help shape programs and policies aimed at increasing female representation and promoting achievement at senior levels in academic STEM fields.

Prevalence of physical inactivity in children and adolescents and the associated epidemic of obesity are increasing concerns. U.S. national health statistics indicate early adolescence (i.e., 10-14 years) appears to be a period of importance regarding physical activity, sedentary behavior, health-related physical fitness, and obesity trends. Considering a significant portion of their waking hours are spent in school, it is widely held that schools' should play a significant role in increasing students' physical activity and health-related physical fitness. To do this, physical education in schools focus on providing quality physical education programs that produce physically literate individuals who have the knowledge, skills, and confidence to enjoy a lifetime of health-producing physical activity. In effect, a call for developing a comprehensive and valid measure of physical literacy has been aptly expressed. Thus, the purpose of this dissertation was to test the psychometric properties of proposed models of physical literacy, examine correlates of the physical literacy factor, and investigate the significance of the relationship between physical literacy and interscholastic sport intention via structural equation modeling. Participants were 400 (231 female, 169 male) sixth-grade physical education students who completed three brief surveys assessing maturation, self-efficacy, self-esteem, knowledge and understanding, motivation, physical activity and sport …

The purpose of this study was to examine the relationship between adolescents' perceptions of their parents' encouragement to lose weight and physical activity habits (i.e., exercise habits and sedentary behaviors) and their own physical health-related fitness (HRF) and psychological well-being. Results of structural equation modeling revealed both similarities and differences between boys and girls. Specifically, parental sedentary behavior and encouragement to lose weight related to girls HRF. Among boys, only encouragement to lose weight related to HRF. When inspecting the relationship between HRF and psychological well-being, HRF related to body satisfaction, but not depressive symptoms, among both boys and girls. Results of this study highlight the complex influence that parental perceptions have during adolescent development.

In order to implement more science, technology, engineering, and mathematics (STEM) into K12 classrooms, it is important to find out whether teachers are comfortable with this pedagogy. To determine teachers' current self-efficacy of STEM pedagogy, teachers in a southern state in the United States were asked to enlighten researchers into this phenomenon. Participants were K12 teachers (n = 119) from a public school district undertaking a district-wide STEM initiative. A measure of STEM teacher self-efficacy and a demographic questionnaire were administered online to participants. STEM teacher self-efficacy data were analyzed, along with demographic data, using descriptive discriminant analysis (DDA) and canonical correlation analysis (CCA). Results suggest some demographic variables are more predictive of STEM self-efficacy (gender, grade level taught, feelings of administrative support, and professional development sessions attended) than others (whether or not gifted courses are taught, age, and length of teaching experience. This data should be used by school administrators that seek to begin or improve STEM pedagogy in their schools.

This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignoring this fourth level, accounting for it using a model-based approach, and accounting it using a design-based approach on parameter and standard error (SE) estimates. Several fixed effect and random effect variance parameters and SEs were biased across all 3 models. In the 4-level model, most SE biases decreased as the number of level 3 clusters increased and as the number of level 4 clusters decreased. Also, random effect variance biases decreased as the number of level 3 clusters increased. In the 3-level and complex models, SEs became more biased as the weight level 4 carried increased (i.e., larger intraclass correlation, more clusters at that level). The current results suggest that if a meaningful fourth level of nesting exists, future researchers should account for it using …

Throughout the scientific literature, researchers have referred to self-respect and self-esteem as being the same construct. However, the present study advocated that they exist as two distinct constructs. In this quantitative study, an instrument was developed to measure self-respect as a construct, and subsequently distinguish that self-respect is distinct from the construct of self-esteem. Exploratory factor analyses (EFA) indicated 32.60% of the variance was accounted for by the 11-item Jefferson Self-Respect instrument (JSR), which measured self-respect as a unidimensional construct. The reliability estimate of the scores from the JSR reached an acceptable α = .82. Fit indices (RMSEA = .031, SRMR = .037, CFI = .982, and TLI = .977) from the confirmatory factor analyses (CFA) signified a well-fitted hypothesized model of self-respect that existed as a unidimensional construct. Additionally, the CFA revealed that the construct of self-respect, and self-esteem was generally distinct, and the strength of the correlation between the two constructs was moderately positive (r = .62).
