Children who are deaf or hard-of-hearing (DHH) exhibit considerable variability in their spoken language and executive function (EF) outcomes, despite on-going improvements in sensory aid technology and public health policies that target early diagnosis and intervention. Maternal parenting cognitions and behaviors (e.g., the patterns of…

Dual-factor models of mental health, those that include risk of psychopathology and wellbeing/protective factors, provide a more comprehensive understanding of an individual's complete mental health. Social-emotional learning (SEL) skills and adverse childhood experiences (ACEs) are each independently linked in the literature with predicting the…

The attrition rate of early career teachers is high. In fact, the government spends $2 billion annually to replace teachers in the first five years of their tenure (Alliance for Excellent Education, 2005). The purpose of this dissertation is two-fold: 1) to test the relationship between purpose, psychological well-being, and affective commitment…

The broad purpose of this study was to address gaps in the literature by applying the Relational Humility Model (RHM; Davis et al., 2010, 2011) to clinical supervision by testing the interpersonal variables of relational humility (RH; Davis et al., 2011), the supervisory working alliance (SWA, Bordin, 1983), and relational behavior (RB; Shaffer…

The purpose of this quantitative correlational predictive study was to examine if and to what extent perceived organizational support (POS) and perceived social support (PSS) predicted turnover intention in female high school principals in the United States. The sample consisted of 88 female high school principals in the United States. The…

Although suicide is now being the second leading cause of death in college and university students, there continues to be a lack of research examining the three types of suicide attempts (i.e., aborted, interrupted, and actual). Interrupted suicide attempts have been found to be predictive of death by suicide, and aborted suicide attempts have…

In three samples (Ns = 286, 304, and 273), we found that endorsement of conspiracy theories, paranormal beliefs, and psychological misconceptions were all positively intercorrelated, supporting an individual difference in the tendency to generally endorse unsubstantiated claims. Multiple regression analyses further supported generality, showing…

This study aimed to assess the association of smartphone addiction with domains of the big five personality traits (i.e., extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) after controlling for individual differences such as age, gender, and amount of daily smartphone and internet use. The study employed a…

Self-determination (SD) is linked to autonomy and better adult outcomes. Adults with autism spectrum disorder (ASD) are often less independent than cognitively matched peers. Given the frequency with which depression co-occurs in ASD and the established association between depression and SD, we sought to evaluate the influence of both ASD severity…

Objective: During the college transition, vulnerability to disordered eating and exercise behaviors and cognitions may increase. We studied how behaviors and cognitions change differentially over time, in the context of gender, athletic participation, and contingencies of self-worth. Participants: 229 diverse, first-year students at a competitive…

Self-construal refers to how individuals view themselves independently from others (Independent self-construal) or interdependently with others (Interdependent self-construal). Although the self-construal theory claimed a connection between self-construal and motivation, none of studies explored the relation between self-construal and reading…

Parental socioeconomic status (SES) strongly influences children's language abilities but less is known about its influence on pragmatic abilities (e.g., inferring intentions from relevance implicatures). Moreover, by focussing on SES, the role of socio-cognitive engagement (e.g., joint parent-child interactions) has been overlooked. We tested…

Purpose: Research remains equivocal regarding the links between hyoid movement and penetration-aspiration. The aims of this study were (a) to explore associations between hyoid parameters, laryngeal vestibule closure (LVC) parameters, and penetration-aspiration on thin liquids; and (b) to determine which of these parameters are the strongest…

The purpose of this longitudinal study was to examine patterns in implementation of Tiers 2 and 3 school-wide positive behavioral interventions and supports (SWPBIS) systems to identify timings of installation that led to higher implementation of advanced tiers. Extant data from 776 schools in 27 states reporting on the first 3 years of Tier 2…

This research investigates the effects of online learning barriers on students' perceived learning and academic achievement. In this study, the barriers identified by Muilenburg and Berge in 2005 were used as online learning barriers. These are (1) administrative issues, (2) social interaction, (3) academic skills, (4) technical skills, (5)…
