The Effectiveness of Child Parent Relationship Therapy (CPRT) for Fathers (open access)

The Effectiveness of Child Parent Relationship Therapy (CPRT) for Fathers

High levels of quality father involvement in childhood are associated with children's socio-emotional, cognitive, and behavioral wellbeing. However, fathers can experience difficulty in building positive relationships with their kids due to work-life balance, lack of relational experience, and other life stressors. The purpose of this study was to assess the effectiveness of child-parent relationship therapy (CPRT) on fathers' parental empathy, parental stress, and child behavior problems. Though an abundance of literature exists to support the efficacy of CPRT, this was the first study to include a randomized controlled design with an all-male sample. This was also the first CPRT study to include both English and Spanish speaking fathers with intervention offered in both languages. Participants were 30 fathers (22 English, 8 Spanish; 53% Latino, 40% Caucasian, 7% Asian) with children between the ages of 3 and 10 (60% male, 40% female; 57% Latino/a, 37% Caucasian, 6% Asian). Fathers were randomly assigned to the experimental group (CPRT) (n = 14) or waitlist control group (n = 16). Results from 2 (Group) by 2 (Time) repeated measures ANOVAs did not yield statistically significant interaction effects on the dependent variables. However, results indicated a statistically significant main effect for time on each dependent …

Mothering while Brown: Latina Borderland Mothers' Experiences of Epistemic Injustice (open access)

Mothering while Brown: Latina Borderland Mothers' Experiences of Epistemic Injustice

Anti-immigrant rhetoric undermines Latinx parents' epistemic legitimacy as producers of valued parental knowledge, irrespective of immigrant status. Little is known about the epistemic harm to Latina mothers who must negotiate their maternal scripts against the backdrop of a parenting discourse steeped in deficit thinking. This study used testimonio to explore the experiences of Latina mothers of young children living in the borderlands of South Texas via a Chicana/Latina feminist epistemological framework that conceptualizes the self as multiplicitous and responsive to the straddling of multiple cultures, nationalities, races, languages, and physical borders. The research questions guiding the study included: (1) How do Latina borderland mothers experience epistemic harm in the context of mothering knowledge? and (2) What strategies do borderland mothers employ to nurture strength and counter epistemic harm? Two theoretical constructs emerged from data analyses. First, the borderland was a site of recurring credibility battles as well as a site of "in-the-flesh" encounters that deepened human connection. Supporting themes included "Brown-on-Brown conflict vs. like-me counters" and "situating injustice vs. denying injustice." The second theoretical construct asserted that borderland mothers' ways of knowing are polyvocal and reflect a Brown body ethic of care. Its two supporting themes included "co-family as sources …

The Effects of Participant Motivation on the Effectiveness of Video Modeling (open access)

The Effects of Participant Motivation on the Effectiveness of Video Modeling

Video modeling interventions have been mostly effective for individuals with autism spectrum disorder (ASD) in teaching social communication skills. However, differences in the effectiveness of these interventions have been noted. Participant motivation was suggested as one of the factors that can influence the effectiveness of video modeling. The purpose of this study was to investigate the effects of participant motivation on video modeling for teaching social communication skills to individuals with ASD. A combined multiple probe across participants and adapted alternating treatments design was used to examine the differential effects of two video modeling conditions (i.e., motivated and non-motivated) on social communication skills of four adults with ASD. Of the four participants, three participants responded to the intervention and performed more of target behavior during the motivated video modeling condition than the non-motivated video modeling condition, while one did not respond to the intervention. In addition, the three participants engaged in a higher percentage of the target behavior during motivated generalization sessions than non-motivated generalization sessions. The results demonstrated that participant motivation influenced the effectiveness of video modeling.

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8 (open access)

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8

This study was intended to evaluate the impact of socioeconomically disadvantaged children's participation in the Texas Home Instruction for Parents of Preschool Youngsters (TX HIPPY) Program on their school readiness and academic achievement. The study used a quasi-experimental design and applied full and optimal propensity score matching (PSM) to address the evaluation concern of the impact of the TX HIPPY program on HIPPY participants' academic achievement compared to non-HIPPY participants. This evaluation targeted former HIPPY participants and tracked them in the Dallas ISD database through Grade Levels K-8. Data were obtained by administering Istation's Indicators of Progress (ISIP) for kindergarten, TerraNova/SUPERA for Grades K-2, and State of Texas Assessments of Academic Readiness for math and reading (STAAR) for Grades 3-8. HIPPY and non-HIPPY groups were matched using propensity score analysis procedures. The evaluation findings show that the TX HIPPY program positively influences kindergarten students to start school ready to learn. The findings of math and reading achievements suggest that HIPPY children scored at the same level or higher than non-HIPPY children did on math and reading achievement, indicating that TX HIPPY program has achieved its goal of helping children maintain long-term academic success. However, the evaluation findings also indicated that …

Reaping the Seeds of Leadership: Evaluating a Proposed Model of Lifespan Leadership Development (open access)

Reaping the Seeds of Leadership: Evaluating a Proposed Model of Lifespan Leadership Development

Though research suggests that several factors are related to the onset of leadership, few researchers have endeavored to determine how these factors may interact to bring about early leadership development. A descriptive discriminant analysis was conducted to test the validity of early factors cited by Murphy and Johnson; namely, lower scores on measures of temperamental negative affect, higher scores of temperamental extraversion, effortful control, orienting sensitivity, authoritative parenting style, secure adult attachment, older relative age, and more reported team sports and extracurricular activities experiences were hypothesized to predict current and past leaders versus never leaders. Additional analyses investigated possible gender differences in how these early factors may predict leader occupancy. The results indicate that early factors are able to predict leadership status for male students, though a majority of the variance in leader status is still left unaccounted. Implications for future leadership development research and training are discussed.

Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review (open access)

Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review

Researchers and publishing guidelines recommend reporting confidence intervals (CIs) not just along with null hypothesis significance testing (NHST), but for many other statistics such as effect sizes and reliability coefficients. Although CI and standard errors (SEs) are closely related, examining standard errors alone in simulation studies is not adequate because we do not always know if a standard error is small enough. Overly small SEs may lead to increased probability of Type-I error and CIs with lower coverage rate than expected. Statistical simulation studies generally examine the magnitude of the empirical standard error, but it is not clear if they examine the properties of confidence intervals. The present study examines confidence interval investigating and reporting practices, particularly with respect to coverage and bias as diagnostics in published statistical simulation studies across eight psychology journals using a systematic literature review. Results from this review will inform editorial policies and hopefully encourage researchers to report CIs.

Complex-Restricted Repetitive Patterns of Vocal Behavior of Individuals with High Functioning Autism: An Innovative Intervention

Access: Use of this item is restricted to the UNT Community
Repetitive verbal patterns of speech are a trait associated with high-functioning autism (HFA). For some, this higher-order restricted, repetitive behavior impedes learning, social opportunities, and access to work environments. Despite emerging motivation for establishing social relationships, some individuals with HFA lack the behavioral prerequisites to establish meaningful relationships. The purpose of this study is to demonstrate the effectiveness of teaching interaction to decrease higher-order verbal restricted and repetitive behaviors (RRBs) for four adults with HFA. Through a multiple baseline design across participants, individuals were exposed to a function-based intervention (i.e., teaching interaction) that systematically taught and reinforced alternative communicative behaviors while interrupting repetitive speech with specific feedback. Teaching interaction effectively reduced RRBs and increased alternative conversation for all four participants. Three of the four participants elected to participate in post-intervention maintenance sessions that occurred in individualized naturalistic settings. Their conversation behaviors maintained with one participant receiving one booster session.

Effects of Telepractice for Training Autism Teachers to Contrive Motivating Operations

Access: Use of this item is restricted to the UNT Community
The rising rate of the autism spectrum disorders (ASD) has resulted in challenges for teachers in public schools, concerning the delivery of evidence-based practices for superior outcomes. Thus, school districts are in need of professional learning options that can be efficiently and effectively delivered to improve the procedural fidelity of interventions. The purpose of this study is to demonstrate the effectiveness of using telepractice to teach autism teachers how to contrive motivating operations to teach manding to students with ASD. By utilizing multiple baselines across participants design, four autism teachers in public schools received intervention support through an online module along with video models as well as direct performance feedback from autism specialists via video-conferencing. The primary dependent variable was the percentage of correct responses from the instructional procedures of task analysis, and the secondary measure was the subsequent rate of student mands. Data were analyzed both visually (i.e., through the study of behavioral patterns) and statistically (i.e., analysis of effect size). Results indicate that telepractice increased accuracy of both teacher and student target responses.

Effects on the Use of Technology-Based Self-Monitoring for Students with Autism Spectrum Disorder: A Meta-Analysis (open access)

Effects on the Use of Technology-Based Self-Monitoring for Students with Autism Spectrum Disorder: A Meta-Analysis

Self-monitoring involves teaching students to be aware of their own behavior, and be able to record whether the behavior happened or not. The present study uses meta-analysis of single case design (SCD) studies to evaluate the effectiveness of self-monitoring interventions that use electronic devices during implementation for individuals with autism spectrum disorder (ASD). Eligible studies were accessed to determine design quality, and examine the use of self-monitoring for individuals diagnosed with ASD. Studies were evaluated against inclusion-exclusion criteria. The studies that met inclusion criteria (n = 15) were assessed with the What Works Clearinghouse (WWC) standards for methodological rigor. The WWC standards were applied to baseline and intervention phases. There were a total of 12 studies with 32 students diagnosed with ASD that met SCD standards without, and with reservations. The 12 studies were evaluated using the Tau-U effect size metric to quantify the percentage of change that was attributed to the self-monitoring intervention. Overall, omnibus Tau-U was 0.96 (95% confidence interval [CI] = [0.89, 1.0]). Limitations and directions for future research are discussed.

Examination of HIPPY Mothers' Parenting Efficacy: Association between Family Structure and Process

This study examined the relationships between family structure (organization and control), family process (cohesion, expressiveness, and conflict) with parenting sense of competency (parenting efficacy) for mothers (n = 138) engaged in Home Instruction for Parents of Preschool Youngsters (HIPPY) related activities. Family structure in this study looked at how the family system is organized regarding clarity of family rules. In addition, family processes of the research participants looked at daily family routines and interactions. General parenting self-efficacy, task-specific self-efficacy for nurturance, and task-specific self-efficacy for teaching which are the dependent variables, looked at the degree to which parents feel competent and capable of solving problems related to these processes in the parent-child relationship. Research questions were answered using multivariate analysis of canonical correlational analysis (CCA) to examine the associations between the independent and dependent variables. Results showed significant relationship between family structure variables of control and organization and parents' self-report of their general efficacy and their task specific efficacy for teaching and nurturing. The study also showed an inverse relationship between process variable of conflict and overall self-efficacy of parents' and their task specific efficacy for teaching and nurturing.

Perceptions of School Administrators on Evidence-Based Practices in Transition Planning for Students with Autism Spectrum Disorder

Access: Use of this item is restricted to the UNT Community
Poor post-school outcomes for young adults with an autism spectrum disorder (ASD) have underscored the need to gain insight into the use of evidence-based practices (EBPs) in the planning and implementation of transition services. EBPs for effective transition planning and implementation have been documented in the literature but do not appear to be fully utilized in practice to achieve desired student outcomes, reflecting a research-to-practice gap. EBPs have the potential to produce positive outcomes at the high school level, if implemented with fidelity. Special education personnel, especially administrators, play a vital and unique role in transition planning. They can either facilitate or hinder the process. This phenomenological study investigated the perceptions of public school administrators regarding the extent of their awareness of EBPs to ensure the successful transition of students with ASD and associated barriers. Semi-structured interviews were conducted with 10 secondary-level public school administrators. Major themes identified through analyzing the qualitative data included (a) a positive vision for students with ASD, (b) characteristics of a good transition program, (c) administrators' roles in the transition process, (d) barriers to EBP implementation, (e) strategies to reduce barriers, and (f) ownership of what administrators can do to remedy the problem.

Relations between Sibling Relationship Quality and Romantic Competence among Young Adults

A primary task of adolescence and young adulthood is to form and develop healthy romantic relationships. While the importance of sibling and romantic relationships have been examined separately, only recently have researchers begun to explore links between the two. The purpose of the present study was to investigate the connection between romantic competence and sibling relationships, especially sibling warmth and sibling conflict, as well as the role of sibling gender constellation in college-aged young adults. This study aimed to examine (a) whether there is an association between sibling relationship quality, such as sibling warmth and sibling conflict, and perceived romantic competence, and (b) the role of sibling gender constellation on the relationship between sibling relationship quality (sibling warmth and sibling conflict) and perceived romantic competence among undergraduate students. Correlation analyses indicated there was no statistically significant correlation between sibling warmth and perceived romantic competence (p > .05), whereas sibling conflict was statistically negative correlated with perceived romantic competence (p < .01). While sibling gender constellation did not have an interaction effect with sibling conflict on perceived romantic competence, which means sibling gender constellation did not have a moderating effect on the relationship between sibling conflict and perceived romantic competence.

Stability and Trajectories of Early Supportive Environment and Adolescents' Depression and Mastery

Previous studies highlighted the importance of parental support for development of mastery of control and depressive symptoms. These studies tended to examine one time wave and outcomes related to that period, forwarding an assumption parenting behaviours do not change as children age. Using the National Longitudinal Survey of Youth 1979-Children and Young Adults, this study filled the gap by examining children's supportive environment at three time points and determining how levels of support across these points impacted children's depression and mastery at 18 years of age. Relative stability of mothers' supportive parenting (i.e., encouragement of social maturity, warmth and affection, and physical punishment) at early childhood, middle childhood, and early adolescence was examined by Kendall's tau correlations. Encouragement of social maturity showed relative stability between early and middle childhood and middle childhood and early adolescence; warmth and affection showed relative stability between early and middle childhood, and physical punishment showed relative stability across all time points. Absolute stability was examined using hierarchical linear modelling and Wilcoxon signed-rank test. No instances were found. Latent class growth analysis identified different trajectories of supportive environment among participants and three groups were identified. Multiple regressions conducted to examine how different trajectories affect late adolescents' …

Adolescent Academic Adjustment during Chronic Illness: Online Training for Child Life Specialists

Frequent absences resulting from a chronic illness can disrupt adolescent school involvement, impacting academic achievement and psychosocial development as a result. This study explores whether certified child life specialists (CCLSs) could be a resource for parents as they address their adolescents' academic disruptions. Specifically, this study assesses an online training program designed to increase CCLSs' knowledge and self-efficacy as related to adolescents' academic adjustment following frequent absences. This knowledge and skill based training was designed as a three part module with sections including: academic considerations, psychosocial considerations, and availability of school resources in promoting successful adolescent academic adjustment. 62 CCLSs were recruited to participate and complete measures evaluating knowledge, in relation to content included in each module, and self-efficacy, involving communication with parents in regards to adolescent academic adjustment. T-tests were conducted to determine whether there were differences in reports of self-efficacy and knowledge following participation in the intervention between and within the treatment and control groups. Results indicate statistical significance for enhanced knowledge and self-efficacy for the treatment group at post-test. Therefore, the outcomes from this study support the effectiveness of brief online training in fostering knowledge and feelings of efficacy for CCLSs in a context not typically included …

The Effects of Graphic Organizers on Building Comprehension in Students on the Autism Spectrum

Many students on the autism spectrum display a strong ability to process and comprehend information at elevated levels when presented with it visually. Despite this, students who have autism are increasingly being educated in general education content classrooms that utilize lessons directed to whole groups of students and limit the use of visually presented material. For some students with an autism spectrum disorder (ASD), this presentation introduces difficulties related to attention as well as comprehension and retention of material. Research indicates promising results associated with using a graphic organizer to increase comprehension accuracy in students who answer wh-questions following the reading of a short passage. The purpose of this study was to document the relationship between using a graphic organizer and increasing reading comprehension. The study employed a single-subject multiple baseline design across participants to evaluate if the use of a graphic organizer impacted the correctness of answering wh-questions for grade-level social studies content. Participants included four eighth grade students in an urban public school who had been diagnosed with ASD. Results supported research by showing an increase in comprehension skills with the use of a graphic organizer.

Establishing Criterion on a Personality-Based Assessment for Employment: A Latent Class Analysis of Faking Behavior

Personality assessments have a long history in psychology and have become the backbone of the human capital management industry, with the Big-Five model being the most prevalent. The central criticism of personality assessments for employment decisions is validity of responses since applicants for employment often endorse items to make themselves more desirable for hire, referred to as faking behavior. The present study examined faking behavior using the Assess Personality Survey (APS). Using a sample of applicant and incumbent data (N = 8,020), the objective was to identify response difference between applicant and incumbents, and the prevalence of faking behavior in applicants. Latent class analysis (LCA) was used to compare groups. Results indicate a clear distinction between applicant and incumbent response patterns. Additional analyses suggest 6 classes of testing patterns among applicants, and results are compared with previous faking identification procedures to improve criteria used to establish faking behavior in respondents.

Radically Early College Entrants on Radically Early College Entrance: A Heuristic Exploration

Despite the fact acceleration has been studied thoroughly as an educational practice for the gifted, early entrance to college specifically has been overlooked. Not only this, but a large portion of this research pertains to early college entrance programs, which provide resources that many early college entrants may not have. The lived experiences and perceptions of radically early college entrants (three or more years advanced) were explored through interviews and heuristic inquiry. The interviews addressed affective aspects of early college foremost, with additional discussion of academic experiences, college choice, and career outcomes. Findings support that radically early college entrants are happy with their choice overall, though more specific findings elaborate on the benefits and limitations of early college, possible regrets, and the social issues this population faces.

Survey of Texas Secondary Transition and Employment Designees' Use of Evidence-Based Practices

The role of transition providers' knowledge of evidence-based practices (EBPs) in secondary transition can only be understood in the context of the dismal post-secondary outcomes of students with disabilities (SWD) and the need for bridging the research-to-practice gap among secondary transition practitioners. A sample of 1,163 Texas Employment Designees (TEDs) were surveyed about their knowledge of secondary transition EBPs. The study examined the psychometric properties and theoretical factor structure fit of a modified version of the Mazzotti and Plotner's Use of Secondary Transition EBPs survey and identified significant effects of TEDs' characteristics on their capacity for implementing secondary transition EBPs (F(9, 110) = 2.16, p = 0.03). Psychometric validation of the instrument indicated overall reliability and internal consistency of the modified instrument in measuring both knowledge and use of EBPs in support and direct provision of transition services (Cronbach's alpha of 0.99). Principal components analysis (PCA) and exploratory factor analysis (EFA) returned a simple one-factor structure. A composite score was developed for the single factor of "capacity", and a subsequent analysis was conducted to determine a relationship between the demographic factors and the overall capacity scores of respondents (n = 198).

Creative Self-Efficacy and Personality: From Imagination to Creativity

Imagination and creative self-efficacy are important components of the creative process and outcomes but are rarely investigated together. To explore the relationship between personality factors, imaginative thinking, and creative self-efficacy, survey responses were gathered from university students in a southwestern region in the United States (n = 1,731). Personality was measured using the International Personality Item Pool (IPIP), imagination was measured using the Imaginative Capability Scale (ICS), and creative self-efficacy was measured using items based on reliability in previous studies. Participants were asked to complete the three surveys along with demographic information through an online format. Confirmatory factor analysis (CFA) was conducted first to confirm measurements used. After fit indices confirmed measurement models used, subsequent analyses were conducted using structural equation modeling (SEM). The model of best fit supported creative self-efficacy as a strong predictor of all three factors of imagination. Additionally, the model indicated a strong relationship between conscientiousness and conceiving imagination as well as other notable relationships with personality factors.

Measurement of Fidelity and Social Validity: Caregiver Application of Trial-Based Functional Analysis Procedures

The present study utilized multiple-baseline and multi-probe across participants designs to measure both fidelity and efficacy of caregivers as primary interventionists when using trial-based functional analysis (TBFA) procedures. Participants included any caregiver of a child with a medical or educational diagnosis of autism and challenging behavior. Caregiver fidelity of implementation of TBFA procedures was measured across three phases: baseline, training, and independent implementation or generalization. Within the implementation phase, caregivers independently conducted TBFAs on their respective children within the home setting. Fidelity, efficacy, and social validity across each participant were measured. Each caregiver was able to reach fidelity during the training phase, and three out of five caregivers were able to identify a clear behavior function for their child's behavior within the implementation phase of the study. Social validity was evaluated. Results indicate that caregivers may be able to supplement traditional interventionists during the TBFA process. Implications for future practice are reviewed.

This study examines the sense of preparedness of preservice special education teachers (PSETs) to instruct English language learners. Pre- and post-survey measures were analyzed using the Wilcoxon signed-rank tests for a group of PSETs as they engaged in their second semester of student teaching experience. To explore emerging themes, a post-qualitative analysis was performed using focus groups. Quantitative results revealed no statistical difference except for the Self-Efficacy subscale. Focus group data showed increased confidence levels resulting from the student teaching experience. A Mann-Whitney U test was used to compare pre-survey results between PSETs who had and PSETs who had not taken advanced coursework or participated in student teaching. With the exception of the subscale, Attitude Towards ELs in the Classroom, results revealed no statistical difference between the two groups. At the same time, qualitative, open-response questions revealed PSETs who had participated in advanced coursework and student teaching seemed to have a deeper understanding of ELs' instructional and linguistic needs. Contributions to the literature are presented which may help in designing teacher preparation programs to increase PSETs' sense of preparedness to better serve ELs with disabilities.

The Roles of Coaches, Peers, and Parents in High School Athletes' Motivational Processes: A Mixed-Methods Study

Grounded in self-determination theory and achievement goal theory, the purpose of this mixed-methods study was to examine the underlying motivational processes from social environments created by coaches, peers, and parents to motivational outcomes in high school athletes, with an emphasis on the relative influence of social agents in basic psychological needs (i.e., autonomy, competence, and relatedness). The quantitative part of this study tested a hierarchical model of high school sport motivation in a final sample of 311 student athletes (204 boys, 107 girls) using structural equation modeling: social factors (coach-, peer-, and parent-created motivational climates) -> psychological mediators (need satisfaction and frustration) -> types of motivation (autonomous motivation, controlled motivation, and amotivation) -> consequences (subjective vitality, athlete burnout, and intention to drop out). Invariance across gender and across team type (varsity vs. non-varsity) was also tested. Adequate model fits were achieved in separate "brighter side" and "darker side" models across the overall sample, gender, and team type. The follow-up qualitative part of this study explored "how" beyond "what" coaches, peers, and parents contribute to the social environments, need frustration, and negative motivational outcomes in sport in a subsample of 37 student athletes (24 boys, 13 girls) who reported high amotivation/burnout …

Comparison of Heterogeneity and Heterogeneity Interval Estimators in Random-Effects Meta-Analysis (open access)

Comparison of Heterogeneity and Heterogeneity Interval Estimators in Random-Effects Meta-Analysis

Meta-analyses are conducted to synthesize the quantitative results of related studies. The random-effects meta-analysis model is based on the assumption that a distribution of true effects exists in the population. This distribution is often assumed to be normal with a mean and variance. The population variance, also called heterogeneity, can be estimated numerous ways. Accurate estimation of heterogeneity is necessary as a description of the distribution and for determining weights applied in the estimation of the summary effect when using inverse-variance weighting. To evaluate a wide range of estimators, we compared 16 estimators (Bayesian and non-Bayesian) of heterogeneity with regard to bias and mean square error over conditions based on reviews of educational and psychological meta-analyses. Three simulation conditions were varied: (a) sample size per meta-analysis, (b) true heterogeneity, and (c) sample size per effect size within each meta-analysis. Confidence or highest density intervals can be calculated for heterogeneity. The heterogeneity estimators that performed best over the widest range of conditions were paired with heterogeneity interval estimators. Interval estimators were evaluated based on coverage probability, interval width, and coverage of the estimated value. The combination of the Paule Manel estimator and Q-Profile interval method is recommended when synthesizing standardized mean …
