    Extending the Efficacy of a Thermal Biofeedback Treatment Package to the Management of Tension-type Headaches in Children

    HEADACHE, Issue 2 2001
    Richard E. Arndorfer PhD
    This study explored the efficacy of a thermal biofeedback treatment package as an intervention with children with tension-type headaches. In a within-subject, time-lagged, multiple baseline design, five children, aged 8 to 14 years, were assigned to baselines of varying lengths prior to receiving treatment. Treatment was introduced sequentially across subjects and involved six thermal biofeedback treatment visits. Parents were also given guidelines for how best to encourage children to independently use the biofeedback skills. Data confirm that the participants learned the handwarming skill, practiced the skill on a regular basis during treatment, and independently used the skills to manage their pain. All participants demonstrated clinically significant reductions in one or more headache parameters (frequency, duration, intensity) following treatment. At 6-month follow-up, four of the five participants were headache-free. Although the thermal biofeedback treatment package was generally effective for these children with tension-type headaches, the specific type of headache experienced by each child appeared to influence the specific response to treatment. In addition, no single measure of headache activity was the best indicator of response to treatment. The efficacy of the thermal biofeedback treatment package is supported as an alternative treatment for children suffering from tension-type headaches. [source]

    Future possibilities of the Linac Coherent Light Source

    JOURNAL OF SYNCHROTRON RADIATION, Issue 3 2004
    M. Cornacchia
    A study of the potential for the development of the Linac Coherent Light Source (LCLS) beyond the specifications of the baseline design is presented. These future developments include delivery of X-ray pulses in the 1,fs regime, extension of the spectral range, increase of the FEL power, exploitation of the spontaneous emission, and a more flexible time structure. As this potential is exploited, the LCLS can maintain its role as a world-leading instrument for many years beyond its commissioning in 2008 and initial operation as the world's first X-ray free-electron laser.

    A preliminary examination of treatment for posttraumatic stress disorder in chronic pain patients: A case study

    JOURNAL OF TRAUMATIC STRESS, Issue 5 2003
    Jillian C. Shipherd
    Abstract Manualized treatments have become popular, despite concern about their use when comorbid diagnoses are present. In this report, the efficacy of manualized posttraumatic stress disorder (PTSD) treatment was examined in the presence of chronic pain. Additionally, the effect of PTSD treatment on chronic pain and additional psychiatric diagnoses was explored. Six female patients with both PTSD and chronic pain following motor vehicle accidents were treated for PTSD using a multiple baseline design. The results indicate that manualized treatment for PTSD was effective in reducing PTSD symptoms in these patients. Although there were no changes in subjective pain, there were pain-related functional improvements and reductions in other psychiatric diagnoses for the majority of patients. [source]

    Using Task Clarification, Checklists and Performance Feedback to Improve the Appearance of a Grocery Store

    PERFORMANCE IMPROVEMENT QUARTERLY, Issue 2 2003
    Leslie Shier
    ABSTRACT An intervention package of task clarification, checklists, and posted performance feedback was developed to increase completion of tasks contributing to the appearance of a local grocery store. The intervention package was based on an informal diagnostic assessment that examined antecedents, equipment and processes, knowledge and skills, and consequences in the organizational environment. A multiple baseline design across five departments was utilized to evaluate the effects of the intervention package on employee cleaning behavior related to the appearance of the store. The results suggest overall improvement of task completion across the five departments observed, with substantial increases resulting from application of the intervention. The mean percentage of tasks completed in the deli department increased by 36%; by 93% in the meat department; by 38% in the frozen department; by 25% in the produce department; and by 34% in the front-end department. The average increase of task completion across departments was more than 45%. The results of this study are consistent with those of Anderson, Crowell, Hantula, and Siroky (1988), as well as with La Fleur and Hyten (1995), demonstrating that task clarification, checklists, and feedback have positive effects on work performance.

    The Behavior Engineering Model at Work on a Small Scale: Using Task Clarification, Self-Monitoring, and Public Posting to Improve Customer Service

    PERFORMANCE IMPROVEMENT QUARTERLY, Issue 2 2001
    John Austin
    ABSTRACT Gilbert's (1978/1996) Behavior Engineering Model (BEM) can enable the success of novice performance engineers by prompting appropriate front-end analysis. This paper describes the third author's first performance improvement project conducted in the customer service department at an insurance agency. Front-end performance analysis informed the design of an intervention package that addressed particular environment and person variables. This package included task clarification, employee self-monitoring, and public posting of group performance. A multiple baseline design across behaviors was used to assess the effects of the intervention. The performance targets were: 1) the percentage of transactions where Customer Service Representatives (CSRs) used customer names, and 2) the percentage of transactions where CSRs suggested additional services available to customers. Average performance during intervention was more than 50% better than average baseline performance for both targets. Results are discussed in terms of the utility of the BEM as a front-end analysis tool that can guide novice performance engineers to build simple and inexpensive, yet effective, performance improvement interventions.

    Effects of a supervisory intervention on assessment of interobserver agreement by educational service providers

    BEHAVIORAL INTERVENTIONS, Issue 2 2008
    Meredith L. Garrity
    Effective data collection requires routine assessment of interobserver agreement (IOA). This study evaluated a supervisory intervention to increase the frequency of IOA assessments performed by educational staff at a school for children with developmental disabilities. Intervention components included action directives, strategic posting of IOA recording forms, and performance feedback (positive reinforcement and correction). Implemented in a multiple baseline design, intervention increased IOA assessments targeting skill acquisition and behavior support plans. The study illustrates a systems-level approach towards performance enhancement of human services personnel. Copyright © 2008 John Wiley & Sons, Ltd. [source]

    Evaluation of a guided compliance procedure to reduce noncompliance among preschool children

    BEHAVIORAL INTERVENTIONS, Issue 4 2006
    David A. Wilder
    The effectiveness of a guided compliance procedure to reduce noncompliance among typically developing preschool children was evaluated. After baseline data on compliance to common demands were collected, a parent, instructional assistant, or graduate research assistant implemented the guided compliance procedure, which involved the delivery of progressively more intrusive prompts contingent upon noncompliance. The effects of the procedure were examined using a nonconcurrent multiple baseline design across participants. The results suggest that the procedure was effective for four of the six children who participated. Copyright © 2006 John Wiley & Sons, Ltd. [source]

    The effect of supervisory feedback, self-recording, and graphic feedback on trainer behavior during one-to-one training

    BEHAVIORAL INTERVENTIONS, Issue 4 2005
    Annemarie van Vonderen
    The effectiveness of supervisory feedback, self-recording, and graphic feedback on trainer behavior during one-to-one training sessions was assessed with three trainers, and three students with mental retardation. Supervisory feedback consisted of a supervisor interrupting the course of the training if an error occurred, administering appraisal when accurate trainer behavior occurred, and prompting the trainer to avoid errors. Following this, self-recording and graphic feedback were in effect. During the latter condition, the trainer was instructed to record her own behavior, to graph the data following each training session, and to set a goal to increase her performance. Data were collected in a quasi non-concurrent multiple baseline design across dyads of trainers and students. The results showed a statistically significant increase of accurate trainer behavior during supervisory feedback, which was maintained during the condition of self-recording and graphic feedback. Maintenance of trainer behavior was recorded during follow-up. The trainers rated supervisory feedback as more acceptable than self-recording and graphic feedback.

    The effect of fluency training on math and reading skills in neuropsychiatric diagnosis children: a multiple baseline design

    BEHAVIORAL INTERVENTIONS, Issue 1 2005
    Stephanie L. Hartnedy
    Fluency (fast and accurate responding) has been found to facilitate the retention, maintenance, endurance, and application of learned skills. Fluency training has been employed effectively in academic, vocational, industrial, and rehabilitative settings. Using a multiple baseline design, this study expanded previous applications by targeting academic deficits of children with neurological and psychiatric diagnoses in a residential treatment facility. Total response rates were measured in 60 second timed probes. Academic tool skills increased and error rates decreased for all participants after implementation of fluency training. Implications for improving attention to task and targeting minimum competency skills are discussed, as is determining the role that practice plays in increasing fluency rate.

    Using habit reversal to treat chronic vocal tic disorder in children

    BEHAVIORAL INTERVENTIONS, Issue 3 2002
    Douglas W. Woods
    In the present study, a nonconcurrent multiple baseline design was used to evaluate the effectiveness of simplified habit reversal in three children diagnosed with chronic vocal tic disorder. In two children, vocal tics were substantially reduced. In a third child, tics were not reduced, and the addition of a supplemental contingency management program was ineffective. Despite these mixed results, the treatment was viewed as acceptable to the children's parents in all cases as measured by a standard index of treatment acceptability. Implications of these findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd. [source]
