The Effects of the Density of Reinforcement on the Maladaptive Behaviors of a Child With Autism

The Effects of the Density of Reinforcement on the Maladaptive Behaviors of a Child With Autism

Date: December 2000
Creator: Motiejunas, Kristina M.
Description: The present study consists of two experiments that analyze the effects of high and low densities of reinforcemnt on the maladaptive behaviors of a 9 year old girl with autism. The first experiment investigates the isolated effects of density of reinforcement on the frequency of maladaptive behaviors during a motor imitation teaching task. High densities of reinforcement produced fewer occurrences of maladaptive behavior than low densities of reinforcement. Experiment 2 analyzes the effects of density of reinforcement during the same teaching tasks as in experiment 1 on maladaptive behavior, task accuracy, prompt resistance, and language. Maladaptive behavior did not recur during experiment 2. High density of reinforcement conditions during the second experiment showed a positive effect on the accuracy of responding and compliance with prompts.

Evaluation of the Easter Seals North Texas Autism Treatment Program: Progress in Meeting Program Mission

Evaluation of the Easter Seals North Texas Autism Treatment Program: Progress in Meeting Program Mission

Date: May 2010
Creator: Pritchett, Malika Naomi
Description: Applied behavior analysis (ABA) remains at the forefront of effective interventions for children with autism. In some cases, the high cost of treatment and other environmental factors limit families from accessing services. The Easter Seals North Texas (ESNT) Autism Treatment Program (ATP) was created to reach high risk, underserved families in the North Texas area by providing early intensive behavioral intervention (EIBI) services to children with autism. This evaluation was conducted to analyze the success of meeting the ESNT ATP program mission to provide culturally responsive ABA to children. The evaluation includes the design of assessments, the analysis of the assessment data, and a set of recommendations to maintain and increase program accessibility.

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Date: May 2010
Creator: Brunson, Lashanna Yvette
Description: This study reports and evaluates child outcome measures at a non-profit autism treatment program providing applied behavior analysis (ABA) based services to children age 3 to 8. To accomplish this, a review was conducted of available outcome data for a 1 year period. Several categories of outcome measures have been reported in the autism treatment literature (post-intervention educational placement, cognitive status, developmental and achievement status and/or progress, autism symptom reduction, and diagnostic reclassification). This study found that the program relied on 2 sources of data to evaluate child outcome: Hawaii Early Learning ProfileĀ® and program goal mastery. Children are making progress as indicated by these measures. The findings are discussed in relation to broader outcome recommendations.

Comparison of client attendance, attrition, and outcomes in 2 class system packages.

Comparison of client attendance, attrition, and outcomes in 2 class system packages.

Date: August 2008
Creator: Berends, Valori
Description: Using the principles of systems analysis as a guide, this study compared two class schedule formats used by Behavior Management and Parenting Services (BMAPS) in order to address the following research questions: 1) What effects do 2 different class formats have on student attrition and appointment keeping? 2) What effects do 2 different class formats have on student outcomes on a pre and posttest assessment? 3) What effects do 2 different class formats have on staff procedures? BMAPS provides parent education to individuals referred by Child Protective Services. The current research included approximately 200 referred clients with an appointment or class scheduled with BMAPS between January 1, 2006 and September 22, 2007. Data was collected by reviewing client files for class attendance and performance records. Results of this study allow BMAPS to enlist the class format that is correlated with better attrition rates and client outcomes.

Increasing activities and interests in a child dually diagnosed with PDD-NOS and DS.

Increasing activities and interests in a child dually diagnosed with PDD-NOS and DS.

Date: August 2008
Creator: Zeug, Nicole M.
Description: Expanding interests may be a behavioral cusp, resulting in widespread changes across skills, and therefore is particularly relevant in intervention programs for children with autism. Little research has addressed directly increasing the diversity of activities and interests for this population. This study describes a program developed to increase activities and interests in a girl dually-diagnosed with pervasive developmental disorder (PDD-NOS) and Downs syndrome (DS). A multiple-baseline design across stimuli was employed to evaluate the program. The results show that the program increased number of total and different toy interactions. No effects were observed for overall duration of toy interactions. Results are discussed in relation to play skill instruction and preference assessment literature, the cusp, and autism intervention programs.

Choices in Reinforcer Delivery

Choices in Reinforcer Delivery

Date: August 2008
Creator: Law, Sarah Ann
Description: The current study consisted of two experiments, both of which were comparisons of choice conditions replicated across four participants. Four typically-developing pre-school children participated in this study. Experiment 1 evaluated participants' preference for choosing consequent stimuli prior to engaging in academic tasks (pre-session choice) versus choosing consequent stimuli each time criterion for reinforcement had been met within the session (within-session choice). In Experiment 2, preference for choice-making was evaluated when outcomes for both choice and no-choice conditions were identical. For two participants, results indicated strong preference for choice-making.

Developing a function-based treatment for problem behavior using a structured descriptive assessment.

Developing a function-based treatment for problem behavior using a structured descriptive assessment.

Date: August 2007
Creator: Harris, Curtis Joe
Description: This study evaluated the utility of structured descriptive assessment (SDA) to generate a hypothesis regarding the operant function of problem behavior when the analogue functional analysis (FA) failed to evoke problem behavior for an adult with developmental disabilities. The effectiveness of interventions based on that hypothesis was evaluated in the natural environment. The SDA succeeded in producing a relatively controlled baseline of problem behavior where the FA and direct observation could not. However, the extent to which treatment procedures affected problem behavior could not be determined due to confounding variables outside the control of the experimenter. The results provide cautionary evidence highlighting both the potential utility of SDA and challenges that may be encountered when conducting SDA and evaluating treatments in natural environments.

Toward a systematic evaluation of evaluating favorable conditions in a parent training program: The pursuit of happiness.

Toward a systematic evaluation of evaluating favorable conditions in a parent training program: The pursuit of happiness.

Date: August 2007
Creator: Broome, Jessica L.
Description: Research has shown that parents of children with disabilities, such as autism, experience significantly higher stress levels than parents of typically developing children. It has been suggested that parent education programs, in particular naturalistic communication training, will reduce parental stress. Most of the literature in this area has relied on parental reports and has only focused on decreasing stress and has not directly addressed increasing alternate feelings, such as happiness. In different but related areas of behavior analysis, an emphasis has been placed on the importance of happiness as a quality of life indicator and that the development of multileveled assessment is sorely needed. This study was designed to analyze one set of measures within a data-based intervention program for parents of toddlers with autism. The Family Connections Project (FCP) is a parent training project designed to enhance the quality of relationships for families who have toddlers with autism. Within this project parents are taught to identify and arrange opportunities to interact with their children in ways that will increase motivation and social responsivity. This study looked at the collateral effects of this training program and investigated if FCP affected the relationship between parents and their toddlers; of particular interest ...

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Soderlund, Michael J.
Description: The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.

Multiple-respondent anecdotal assessments for behavior disorders; An analysis of interrater agreement and correspondence with treatment outcomes.

Multiple-respondent anecdotal assessments for behavior disorders; An analysis of interrater agreement and correspondence with treatment outcomes.

Date: May 2007
Creator: Wolf, Roxanne
Description: The current study was designed to further evaluate the usefulness of anecdotal assessments. The goal of this study was to evaluate the overall agreement between multiple respondents on the primary function of aberrant behavior using the Motivation Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST) and, if agreement was obtained, to assess the effectiveness of treatment based on the outcome of the assessments. Results showed that anecdotal assessments were able to identify the general type of contingency maintaining two participants' problem behavior. However, for one participant the assessments did not correctly identify the specific form of reinforcement (attention or tangible items) that maintained the aberrant behavior.
