The purpose of this study was to determine that a behavioral lifestyle modification approach to weight loss changes participants' dietary intake and physical activity levels and that these changes were associated with weight loss and weight loss maintenance. Behavioral factors important in other weight control studies were also investigated to see if they are important indicators of successful weight control in this program as well. A group of previously validated questionnaires, along with a weight history written for this study, was administered to current participants in Providence Health System's Smart CHOICES program both before and after program participation. The same questionnaires were administered to past participants in a one-time follow-up for the CHOICES program approximately 2 years after program completion. The study found that current participant successful weight losers did decrease their percentage of energy intake from fat more than did non-successful weight losers over the course of the program. Also, successful weight losers decreased their caloric intake and increased physical activity levels during the program and these changes did not occur in non-successful weight losers. The Eating Inventory scales for cognitive restraint and Westenhoefer's flexible control showed expected increases and disinhibition and hunger scores showed expected decreases among successful weight losers. However, non-successful weight losers showed these same changes except for the hunger scores, which did not decrease during the program. There were no differences found between past participant weight loss maintainers and non-maintainers in caloric intake, percentage fat intake, physical activity levels, Eating Inventory scales, or flexible and rigid control. When compared to successful weight losers among the current participants, there were suggestions that past participant weight loss maintainers and non-maintainers regressed toward their pre-treatment levels in percentage of fat intake, physical activity levels, and flexible control scores over time. While the Smart CHOICES program is effective in bringing about short-term behavior change to produce weight loss, maintenance of weight loss is a problem in this program as it is in other lifestyle modification programs. The factors differentiating successful weight maintenance from weight regain after loss in this program were not identified. / Graduation date: 2002

Continuing education programs are successful only to the extent that the recommended practice or behavior is implemented. Previous research has demonstrated that some programs result in behavior change and others fail to do so. A conceptual framework developed by Cervero links behavior change to continuing professional education. This descriptive correlational study examined factors related to implementation of knowledge gained from a continuing professional educational offering into practice among registered nurses. One questionnaire on the motivation of the individual professional was given prior to the continuing professional educational offering and three other questionnaires eliciting the participants perception of the social system, nature of the change and the continuing educational offering was given upon completion of the class. Two months following the offering a self-report evaluation, a Likert scale instrument and an open-ended questionnaire, was completed by the participants to measure the change in behavior after the learning experience. Demographic data of the participants was also correlated with nursing behavior. The rights of the participants were protected at all times. Participants were asked to participate on a strictly voluntary basis. Findings of the study indicated that the variables of the individual professional, the continuing educational offering, the nature of the change and social system did not statistically correlate with the outcome variable of behavior change. However, the responses to the open ended questionnaire contradicted the statistical findings. Participants articulated numerous ways in which their nursing practice had changed as a result of their continuing education experience. Conclusions of the study were that there is no statistically significant relationship between the independent variables and the dependent variable of behavior change, but that qualitative data indicated that change in nursing practice did occur following the continuing professional education offering. Implications from the study indicate that the process of continuing professional education is complex with multiple variables. There is a need for further research to delineate the influence of these variables on behavior change in nursing practice. Then, those planning educational offerings could work effectively with their clientele to more dramatically improve health care and client outcomes. / School of Nursing

This study evaluated the effects of priming and contingent attention procedures on play variability in a child with autism. During baseline, numbers of novel play episodes, different play episodes, and actions occurred at low rates. Priming procedures did not produce desired change. When contingent attention was implemented, significant increases occurred in novel play episodes, different actions, and different play episodes. These results show that attention contingent on variable play episodes can increase the number of novel responses to play materials. The results are discussed within the context of treatment and future research.

This study investigated effects of monitoring on correspondence between nonverbal responding and verbal descriptions of those contingencies, when verbal descriptions and contingencies were compatible and when incompatible. In the Nonverbal Component, the contingency for key pressing was either on a 0.8 s IRT or a 3.4 s IRT. In the Verbal Component, subjects made responses to a statement about the contingency for reinforcement in the Nonverbal Component. Shaping was used to establish targets of 0.8 s and 3.4 s in this component. Results indicated that across 7/8 opportunities subjects exhibited nonverbal and verbal behavior that was sensitive to their respective contingencies regardless of compatibility. This sensitivity to contingencies was not affected by the presence of a monitor.

A functional analysis, conducted to assess the variables maintaining the chronic eye poking of a female diagnosed with profound mental retardation, indicated that the behavior persisted in the absence of social contingencies. A procedure was initiated in a training environment in which a punisher (mild reprimand) was delivered contingent on eye poking in the presence, but not in the absence, of a neutral stimulus (wristbands). Using a combination of multiple baseline and multielement experimental designs, it was determined that that eye poking was suppressed in the presence of the previously neutral stimulus, even in environments in which the reprimand contingency was inoperative.

The purpose of this study centers around the development of speech in a non-verbal eight-year-old boy through the use of behavior modification techniques.

This study was an objective investigation of an operant program in behavior modification using tangible reinforoers, which was conducted in two Special Education classes in the Denton Independent School District.

The purpose of the present study was to compare their (avoidance contingency and positive-reinforcement contingency) relative effectiveness in producing a desired behavior.
