accuracy and Preference Assessment of prefilled insulin pen versus vial and syringe with diabetes patients caregivers and healthcare professionals
Current Medical Research and Opinion, 2013Co-Authors: Andreas Pfutzner, David C. Klonoff, Marcus Niemeyer, Timothy L. Bailey, Carlos Campos, German Guerrero, Douglas Kahn, Ellen Ambers, Irina NaybergAbstract:AbstractObjectives:The primary objective of this study was to investigate the dosing accuracy of the new prefilled FlexTouch insulin pen (FT) in comparison to conventional vial and syringe (V&S) when used by patients (Pts), caregivers (CG) and healthcare professionals (HCPs).Methods:A total of 120 subjects participated in the trial (40 diabetes patients aged 61 ± 11 [mean ± SD] yrs, 20 caregivers [parents and other relatives], 20 physicians, and 40 nurses/certified diabetes educators). The participants were introduced to the devices in randomized order and were asked to perform injections of 5, 25, 43 and 79 IU doses into laboratory tubes. Dosing accuracy was analyzed by weighing the tubes on a pharmaceutical balance and calculating the mean absolute deviation (MAD) from the intended doses. After completing a device Assessment questionnaire, Patient Perception Questionnaire (PPQ), with questions regarding device design and performance, the procedure was repeated for the other device, and the patients were...

comparison of the predictive validity and consistency among Preference Assessment procedures a review of the literature
Research in Developmental Disabilities, 2013Co-Authors: Soyeon Kang, Mark F Oreilly, Giulio E Lancioni, Terry S Falcomata, Jeff Sigafoos, Ziwei XuAbstract:Abstract We reviewed 14 experimental studies comparing different Preference Assessments for individuals with developmental disabilities that were published in peer-reviewed journals between 1985 and 2012. Studies were summarized based on the following six variables: (a) the number of participants, (b) the type of disability, (c) the number and type of stimuli, (d) the average duration of administration, (e) compared procedures, and (f) results. Studies were also classified in terms of the predictive validity and consistency of the Preference Assessment results. The results suggest the Preference Assessment procedures that may produce more accurate predictions for the reinforcing effects of identified stimuli and consistent Preference results. The findings are discussed in relation to the previous literature. Evidence based modifications of the most efficient Preference Assessment are also discussed.

choice and Preference Assessment research with people with severe to profound developmental disabilities a review of the literature
Research in Developmental Disabilities, 2005Co-Authors: Helen Cannella, Mark F Oreilly, Giulio E LancioniAbstract:Since the last major empirical review on choice interventions and Preference Assessments among people with severe to profound developmental disabilities (Lancioni, O'Reilly, & Emerson, 1996) the body of research in this area has grown extensively. This paper reviews thirty studies carried out between 1996 and 2002 that have been sorted into four categories. These categories are (a) building choice opportunities into daily contexts; (b) assessing the effects of choice making on various parameters of behavior; (c) assessing Preferences; and (d) assessing the effectiveness of various Preference Assessment formats. The main findings in these studies were that choice interventions led to decreases in inappropriate behavior and increases in appropriate behavior, and that various Preference Assessments could be used to identify reinforcing stimuli. The findings are discussed in relation to technical and practical rehabilitation questions. Potential issues for future research are also examined.

a method to assess relative Preference for training and environmental enrichment in captive wolves canis lupus and canis lupus arctos
Zoo Biology, 2015Co-Authors: Nicole R Dorey, Lindsay R Mehrkam, Jay TaceyAbstract:It is currently debated as to whether or not positive reinforcement training is enriching to captive animals. Although both husbandry training and environmental enrichment (EE) have been found to benefit animal welfare in captivity, to date, no systematic investigation has compared an animal's Preference for performing a trained behavior to engaging freely with a stimuli provided as EE. In the current paper, we used four captive wolves to (1) test the efficacy of a paired-stimulus Preference Assessment to determine Preference for engaging in a trained behavior as a choice; and to (2) use a paired-stimulus Preference Assessment to determine whether or not individuals prefer to engage in a previously trained behavior versus a previously encountered EE stimuli. Of the four subjects tested, visual inspection of the graphs revealed that two of the subjects preferred trained behavior stimuli and two of the subjects preferred EE stimuli; only one of the wolves had a statically higher Preference for an EE stimulus over a trained behavior. We believe that letting the animals choose between these two events is the first step in answering the question of whether or not is training enriching, however more research needs to be done and suggestions for future research is discussed.

A Two-Choice Preference Assessment With Five Cotton-Top Tamarins (Saguinus oedipus)
2015Co-Authors: Eduardo J. Fern, Nicole R Dorey, Jesús Rosales-ruizAbstract:A study selected 5 cotton-top tamarins (Saguinus oedipus) located at the Frank Buck Zoo in Gainesville, Texas, for a food Preference Assessment. The study used a paired-choice procedure across 7 different food items for all 5 tamarins. Preferences for the food items across all the tamarins varied, although general trends were noted as well. This article discusses the benefits of using paired-choice Preference assess-ments in zoo settings. During the past several decades, a number of researchers have attempted to quantify food Preferences, (Thompson & Grant, 1971; Young & Chaplin, 1945; Young & Kappauf, 1962). However, only recently have researchers in applied settings focused on systematic Preference Assessments. Much of this research has focused on choosing one stimulus more frequently than another (Pierce & Epling, 1999). Several of the Preference Assessments developed include single-, paired-, and multiple-stimulus methods. Fisher et al. (1992) developed a systematic approach to differentiate between preferred and nonpreferred stimuli. They described a method in which stimuli were presented in concurrent pairs to an individual who then would select one of the stimuli (paired choice). When every combination was presented, the researchers then ranked the stimuli on the percentage of times an individual selected that stimulus. Fisher et al. (1992

Is Preference a predictor of enrichment efficacy in Galapagos tortoises (Chelonoidis nigra)
Zoo Biology, 2014Co-Authors: Lindsay R Mehrkam, Nicole R DoreyAbstract:It is widely acknowledged that environmental enrichment plays an important role in promoting the welfare of captive animals. However, a topic of debate is whether an animal's Preference for an enrichment strategy is any indicator of its efficacy. In addition, relatively few studies have evaluated environmental enrichment strategies for non-mammalian species. In the present study, we compared the results of an observational evaluation of enrichment efficacy with the results of a paired-stimulus Preference Assessment for three Galapagos tortoises. In the observational study, object enrichment (boomer balls and a free-flowing sprinkler) and keeper interactions (shell scrubbing and neck rubbing) were evaluated systematically for their effects on locomotion, species-typical behavior, aggressive and non-aggressive conspecific interactions, and enclosure. Preference Assessments were subsequently conducted in which subjects could choose the enrichment strategy to be implemented. All subjects preferred keeper interactions consistently over object enrichment. Our results suggest that enrichment Preference was a variable predictor of efficacy across enrichment species-typical behavior, activity levels, enclosure use, and aggressive and non-aggressive conspecific interactions strategies. Preference predicted efficacy for promoting species-typical behavior (1/3 subjects), activity levels (2/3 subjects), and enclosure use (2/3 subjects), but not conspecific interactions (0/3 subjects). The results suggest that Preference may be an efficient predictor of enrichment efficacy when daily observational evaluations are not practical; however, the predictive utility of Preference Assessments may depend on the behavioral goal of the enrichment strategy. We discuss the need for future research examining the relationship between Preference and enrichment efficacy-as well as other potential indicators of enrichment effectiveness-in captive animals.
