FUNCTIONAL ANALYSES: A COMPARISON OF ISOLATED AND SYNTHESIZED CONTINGENCIES

Graley, Devin N. 01 January 2019 (has links)
The purpose of the study was to compare traditional functional analysis procedures (isolated contingencies) to functional analysis procedures which are modified to include nuanced environmental variables (synthesized contingencies) for children in an outpatient setting in order to determine sensitivity to the isolated or synthesized contingencies. A multi-element design embedded into a multi-treatment design was used to evaluate differentiated rates of challenging behavior across the two analyses for three children exhibiting challenging behaviors. The results supported the utility of the traditional functional analysis (FA) procedures when compared to that of the interview informed synthesized contingency analysis (IISCA) for one of three participants.

EFFICIENT IDENTIFICATION OF FUNCTION: A COMPARISON OF DIFFERENT IMPLEMENTERS DURING FUNCTIONAL ANALYSES

Nicklow, Katelyn E. 01 January 2019 (has links)
Functional analyses (FAs) are a common tool used in the assessment and treatment of severe problem behaviors and often occur in the context of clinical settings with unfamiliar, trained staff. Previous research suggests that inconsistent outcomes can emerge when caregivers with an existing history of seeing their child’s challenging behavior are trained to implement the assessment in place of clinical staff. The purpose of the current study was to expand on existing literature by comparing FA implemented by clinical staff and caregivers in the context of a clinical setting. Results demonstrate that efficient identification of function and differentiated rates of problem behavior given the inclusion of caregivers during assessment may vary based on the child’s existing history of responding with those caregivers. Implications of results for researchers and practitioners are discussed.

Workplace Aggression: A Multi-Study Examination of Work and Nonwork Consequences

Demsky, Caitlin Ann 22 May 2015 (has links)
Workplace aggression has been associated with a number of detrimental employee and organizational outcomes, both at work and away from work. This dissertation includes three studies that expand our knowledge of the implications of workplace aggression in the work and nonwork domains. Further, this research illuminates the processes through which this relationship occurs by utilizing various sources of data from employees in a variety of contexts including universities, long term health care, and the USDA Forest Service. In Study 1, which was published in the Journal of Occupational Health Psychology, multi-source data are utilized to identify the indirect effects of coworker-reported workplace aggression on self and significant-other reported work-family conflict via self-reported psychological detachment from work. Study 2 identifies an indirect effect of workplace aggression on parental warmth via increased perceived stress utilizing longitudinal data from the Work, Family, and Health Network. Finally, Study 3 utilizes data from the USDA Forest Service to examine associations between workplace aggression and safety outcomes. Workplace aggression was found to be associated with increased resource depletion (i.e., rumination, cognitive failure) and decreased workplace safety (i.e., increased workplace accidents, decreased safety compliance). Workplace aggression was indirectly associated with safety participation and workplace injuries via cognitive failure and rumination, respectively. Safety climate, an organizational resource, moderated the relationship between rumination and safety behaviors. Finally, the indirect effect of coworker aggression on safety compliance via rumination was found to be conditional on low levels of safety climate, while the indirect effect of supervisor aggression on safety participation via rumination was also found to be conditional on low levels of safety climate. The current body of work provides implications for developing workplace interventions to reduce negative outcomes of workplace aggression, such as general stress management and recovery from work interventions. Several avenues for future research are suggested as well, including examining objective health outcomes of workplace aggression, utilizing longitudinal designs, and identifying additional moderators of the association between workplace aggression and employee outcomes.

Dynamic Job Satisfaction Shifts: Implications for Manager Behavior and Crossover to Employees

Caughlin, David Ellis 21 May 2015 (has links)
In this dissertation, I investigated job satisfaction from a dynamic perspective. Specifically, I integrated the momentum model of job satisfaction with the affective shift model and crossover theory in an effort to move beyond traditional, static conceptions of job satisfaction and other constructs. Recent research and theoretical development has focused on the meaning of job satisfaction change for workers and how such change impacts their decisions to leave an organization. To extend this line of inquiry, I posited hypotheses pertaining to: (a) job satisfaction change with respect to positive work behavior (i.e., organizational citizenship behavior, family-supportive supervisor behavior); (b) the potential moderating effect of changes in negative work events (i.e., job demands, interpersonal conflict) on the relation between job satisfaction change and turnover intentions change and positive work behavior; and (c) the crossover of job satisfaction change from managers to employees and the potential underlying behavioral mechanisms. An archival dataset collected by the Work, Family & Health Network was used to investigate the aforementioned phenomena. Data were collected at two time points with a six-month interval via face-to-face computer-assisted personal interviews from individuals working at 30 facilities from a U.S. extended-healthcare organization. In total, data from 184 managers and 1,524 of their employees were used to test hypotheses. Data were analyzed using multilevel structural equation modeling. In an extension of the momentum model, I found that managers’ job satisfaction change positively related to changes in employee reports of their FSSB; in addition, I replicated prior findings in which job satisfaction change negatively related to turnover intentions change. Furthermore, based on my integration of the momentum model and the affective shift model, I tested the proposition that changes in negative work events (i.e., job demands, interpersonal conflict) would moderate the relationship between changes in job satisfaction and focal outcomes. For certain operationalizations of negative work events, hypothesis testing revealed significant interactions with respect to changes in all three outcomes: turnover intentions, OCB, and FSSB. The form of the interactions, however, deviated from my predictions for models including changes in turnover intentions and OCB, although my predictions were supported for models including changes in FSSB. In my integration of the momentum model and crossover theory, the associated hypotheses were met with very limited support. Specifically, the relationship between managers' job satisfaction change and employees' job satisfaction change approached significance, but the relationship between managers' level of job satisfaction and their employees' subsequent level of job satisfaction did not receive support. Similarly, the proposed mediational mechanisms (i.e., managers' OCB and FSSB) of these crossover relations went unsupported. In sum, while my contributions to the momentum model and the affective shift model were notable, my proposed integration of the momentum model and crossover theory was met with limited support. Overall, findings from this dissertation yield important implications for both theory and practice, as they may draw more attention to changes in job satisfaction, as well as the potentially beneficial role of changes in perceived negative work events.

Using Acoustical Feedback to Improve Elementary School Student Behavior during Transitions

Altman, Lauren Danielle 25 March 2015 (has links)
Behavior during transitions in classrooms is an area in need of additional supports in order for teachers to effectively manage classrooms. Extended transition durations, particularly transition periods between one activity and another are related to problem behavior among children in educational settings. This study evaluated the use of acoustical feedback aimed to improve transition behaviors of elementary school students, using a multiple-baseline design across participants. Teachers were trained to implement the acoustical feedback procedure. Data on teacher treatment fidelity, student transition behavior (transition duration and problem behavior), generalization probes, and social validity were collected to examine the feasibility and potential efficacy of acoustical feedback. The results indicated that the participating teachers successfully implemented the acoustical feedback procedures with high levels or moderately high levels of fidelity and their implementation of the intervention was successful in reducing problem behavior and transition duration for all three participating children. Support for generalization was strong for two teachers and their students and minimal for one teacher and her student.

An Evaluation of the Prevent-Teach-Reinforce Model within a Multi-Tierred Intervention System

Barnes, Sara Amanda 18 March 2015 (has links)
This study assessed the Prevent-Teach-Reinforce (PTR) model to determine its impact on problem and replacement behaviors of three children who are typically developing with behavioral challenges in a high-need elementary school setting. Specifically, this study evaluated the use of the PTR model as an intensive individualized Tier 3 intervention within a multi-tiered intervention system. In addition, the study examined the validity and usability of the Individualized Behavior Rating Scale Tool (IBRST), which was developed as a feasible daily progress monitoring tool in conjunction with the PTR model. Social validity and fidelity of intervention implementation were also assessed. A multiple baseline across participants was employed to evaluate the impact of implementation of the model on the children's behaviors. The results of the study indicated that the PTR model was effective in reducing problem behaviors and increasing the use of replacement behaviors for all three participants. In addition, the IBRST completed by the teachers was found to have a substantial correlation to data collected during direct observations.

Behaviorally-Based Interventions for Improving Social Interaction Skills of Children with ASD in Inclusive Settings: A Systematic Review and Meta-Analysis

Camargo, Siglia 14 March 2013 (has links)
Students with autism spectrum disorders present deficits in social interaction skills that may prevent their successful inclusion in general education placements. Considering the increasing number of children with autism spectrum disorders (ASD) being educated in inclusive settings and recent requirements on the use of research-based interventions in schools, the purposes of this study were (1) to evaluate the quality of single-case research and determine whether behaviorally-based interventions to improve social interaction skills of children with ASD in inclusive settings can be considered evidence-based practices and (2) to conduct a meta-analysis investigating whether specific factors such as participants' age, behavioral components used in the intervention, target social interaction skills, intervention implementer, and peer training moderate effectiveness of the interventions. Specific criteria for quality of single-case research were used to classify studies according to their certainty of evidence. Tau-U, a non-parametric index of effect size in single-case research, was used to measure the intervention's magnitude of change on target outcomes. Differences between levels of the moderators were analyzed using statistical significance test (p = .05) through the use of 83.4% confidence intervals. Results indicate that the use of behaviorally-based interventions to improve social interaction skills of students with ASD in inclusive settings can be considered evidence based practices. In addition, the interventions produced overall high effect size, indicating their effectiveness based on studies meeting minimum standards of methodological quality. More specifically, the interventions are demonstrated to be effective for preschool and elementary school children between the ages of 2 and 10 years. Studies targeting social interaction initiations or responses in isolation were more effective than studies focusing on both skills. While interventions using planned reinforcement were shown to be more effective, no differential effects were found regarding the use of planned modeling. No differences were found regarding intervention implementer. Finally, the use of peer training did not appear to increase effectiveness of the behaviorally-based social skill interventions. The results and their implications for practice and future research are discussed.

DEVELOPMENT OF AN AVIAN MODEL FOR IDENTIFYING INDIVIDUAL DIFFERENCES IN DRUG VULNERABILITY

Rice, Beth A 01 January 2015 (has links)
The attribution of incentive salience to cues that become associated with drugs of abuse is a critical characteristic of individuals who may be vulnerable to drug addiction. Rodents with the propensity to sign track are thought to be vulnerable to drug abuse. The goal of the current work was to investigate whether sign trackers (STs) would acquire cocaine conditioned place preference (CPP) to a discrete cue using an avian species. In Experiment 1, sign and goal trackers (GTs) were first identified using a one third rank order split. Following identification, cocaine-CPP was conducted with a discrete cue in each end chamber. Contrary to previous research, results showed that GTs showed a CPP to the discrete cue but STs did not. Experiment 2 was conducted to determine whether sign and GTs had been misclassified with the rank order split. Experiment 2 compared the rank order method with a t-test method (absolute criterion). Misclassification of both sign and GTs occurred using the rank order split. The findings indicated that use of a more accurate method to identify sign and GTs may have led to different results for Experiment 1. The t-test method may be useful for models that require identification of STs.

Evaluation of Using an Interrupted Behavior Chain Procedure to Teach Mands to Children with Autism

Jacobsen, Blair Nichole 01 January 2013 (has links)
Abstract Interrupted behavior chain procedures have been shown to be an effective way to teach individuals with intellectual disabilities and autism to mand for missing objects and information concerning missing objects. Research has shown that an interrupted behavior chain procedure is more effective than traditional mand teach trials, which occur at the onset of a behavior chain or in a massed trial format. However, there is a lack of research evaluating the use of interrupted behavior chain procedures to teach vocal mands for missing items and the possible generalization effects thereof. This study evaluated the acquisition of vocal mands for missing items using interrupted behavior chain procedures, as well as participants' generalization of learned mands to novel behavior chains when said chains were interrupted. Each participant exhibited some form of generalization to a novel chain suggesting that interrupted behavior chains may be an efficient means to teach mands to children with autism. However, the extent to which a mand generalized across topographically distinct chains was different for each participant, suggesting that an individual's verbal repertoire could be a factor influencing generalization.

An Evaluation of the Family-Centered Prevent-Teach-Reinforce Model with Families of Young Children with Developmental Disabilities

Bailey, Kathleen 01 January 2013 (has links)
Daily routines in the home are typically the most common interactions for children with their siblings and parents. When a child exhibits challenging behavior in these routines, it can cause a strain on the family as well as the child's ability to learn a more appropriate behavior. This study examined the feasibility and potential efficacy of an adapted version of the Prevent-Teach- Reinforce (PTR) intervention with three families of young children with developmental disabilities. The school-based PTR manual was adapted for treatment use in a family context. The study assessed the family adherence to the collaboratively developed PTR intervention, family use of the behavior rating scale, social validity, procedural integrity, and child behavior behaviors during the routines. A multiple-baseline design across children was used to examine the impact of the PTR intervention on child behavior within the routine. Results indicated that the PTR interventions were successful in demonstrating an increase in appropriate behaviors and a decrease in challenging behaviors across children. The results also indicated that parents were able to successfully use the behavior rating scale to measure each child's behavior.
