Performance feedback plays an important role in management accounting, as it is integral to performance measurement and evaluation. The timing of performance feedback is a critical characteristic of accounting information systems and is often a choice variable for managers and management accountants. In this dissertation, I examine the relation between the timing of outcome-based performance feedback and individual performance. I find that immediate outcome-based performance feedback, while benefiting current performance, can limit individuals’ propensity to seek learning opportunities, reducing future performance. Further, I find that feedback given after intermediate delays benefits future performance with a small cost to current performance. Lastly, feedback given after too long of a delay not only limits current performance, but also limits future performance due to the effects of information overload. Overall, I find support for an inverted-U relation between the timing of performance feedback and future performance. In a two-period setting in which the timing of outcome-based performance feedback is manipulated in the first period and feedback is unavailable in the second period, I find that participants given intermediate feedback perform significantly better in the second period than those given feedback either after no delay or after a long delay. I also investigate the processes by which performance is affected by the timing of performance feedback. These results contribute to a better understanding of the effect of performance feedback timing in complex task environments and provide insight into how delays in performance feedback can benefit or harm future performance. / text

Background: Commonly used response scales in patient-reported outcome (PRO) measures include the visual analogue scale, 11-point numeric rating scale, 5-point numeric rating scale, 5-point verbal rating scale, and 5-point verbal-numeric rating scale. Although prior studies have explored the interpretation of response scale labels and compared scores resulting from the response scale, many questions remain. Purpose: To identify sets of verbal descriptors interpreted with the least variation and to explore whether the response scales provide interval level data and whether the scales are interchangeable. Methods: Subject recruitment and screening was through an online drug-drug interaction service (MediGuard.org). Via an online survey platform, subjects used a scale (0 = lowest possible and 10=highest possible) to assign interpretation scores to verbal descriptors. Repeated measures analysis of variance informed the test interval data between scores. Subjects also completed repeated administrations of four symptom-specific item stems with different response scales. Ordinal regression informed the analysis of scores assigned to verbal descriptors, comparison of probabilities of responding in given categories across scales, and prediction of response category on one scale conditional on observed response on another scale. Cut-points informed tests for interval level data. Results: The sample (n=350) comprised 223 females and 127 males with a mean (SD) age of 56.9 (12.1) years. Number of health conditions per subject ranged from 1 to 12 (median = 5). Age, sex, level of education, and number of health conditions were associated with the interpretation of verbal descriptors. Scores assigned to "poor," "fair," "good," "very good," "excellent," "somewhat," "sometimes," and "quite a bit," had the largest variation. The probability of responding in the same categories on the different response scales was significantly different across scales before and after collapsing categories. No scale yielded interval level data. The 11-NRS data tended more towards interval level than the data from other scales. Conclusions: Using different response scales with verbal descriptors in non-randomized studies may introduce bias. Differential item functioning and subgroup analyses should be investigated in the development and use of these response scales. The scales are not interchangeable. Compared with other scales the 11-NRS produced data approaching interval level. Collapsing categories entails significant probabilities of misclassification.

The purpose of this study was to evaluate liver transplant recipient factors associated with postoperative complications leading to longer intensive care unit (ICU) length of stay which in turn may increase hospital morbidity and mortality. A retrospective, correlational design was developed with a sample of 230 participants. Data were collected for liver transplant recipients over a four-year period (June 2007-December 2011) from the electronic medical record and the transplant database. T test and binary logistic regression were used to assess for the factors predictive of ICU complications, ICU length of stay (LOS), hospital length of stay (HLOS), and overall morbidity and mortality. Data were collected from three time periods: preoperatively, intraoperatively, and postoperatively. The factors identified as statistically significant were cold ischemic time, lowest intraoperative glucose, postoperative four-hour blood urea nitrogen (BUN), Postoperative Day 1 (POD 1) hematocrit, postoperative lowest systolic blood pressure, and fresh frozen plasma (FFP) transfusions. Mortality occurred in 1 recipient in the >9-day ICU stay group, and 7 deaths were noted in the >19-day hospital LOS group. Age of recipients who died was 48-59 (6 males, 2 females), with 7 Caucasian and 1 Other. Comorbidities of these deceased recipients were diabetes and obesity with MELD scores of 18-45. Complications experienced by recipients included: 6 with renal failure, 2 with sepsis, 3 with graft dysfunction, and 1 with cerebral edema. Findings from this study showed factors that impact ICU LOS, HLOS, and mortality, including BUN, glucose, and hematocrit. Implications for practice are that these factors should be closely monitored in the pre-, intra-, and postoperative time periods to reduce risks of complications to transplant recipients. Future research should include further evaluation of the factors associated with poor transplant outcomes, including glucose, continuous renal replacement therapy (CRRT) use, age, and gender. Nurse researchers must continue to strive to understand the pathophysiological mechanism of liver disease to reduce ICU complications ultimately to improve the care and outcomes of liver transplant recipients while reducing ICU LOS and HLOS.

This study investigated the relationships among attachment styles, affect regulation, and outcome in a clinical sample receiving treatment for depression. Sixty-six clients completed questionnaire measures of adult attachment, dysfunctional attitudes, interpersonal problems, self-esteem, and depression. Clients’ levels of affect regulation were assessed with an observer-rated measure of affect regulation. The study’s purpose was to extend previous research by examining the relationship between adult attachment and affect regulation within a clinical context. Results indicated significant and positive associations between clients’ attachment security and their levels of affect regulation at early and late stages of psychotherapy. Late modulation of expression and arousal were found to mediate the relationship between pre-treatment attachment insecurity and outcome. Pre-treatment attachment avoidance, characterized by high discomfort with closeness, had a direct relationship with depressive symptoms not mediated by the cognitive-affective processes of affect regulation. Implications of present findings for the treatment of depression are discussed.

Despite the evident advantages of assistive technologies, many are still abandoned within the first few months of use. The key to changing this may lie in the assessment process, which has been described as the most consequential phase in the provision of assistive technology [14]. The purpose of this research was to create a protocol for the assessment and delivery of individualized access technologies based on the concepts of response efficiency theory. The protocol was applied with three children, ages 12 to 14, who were seeking new access technologies. The results suggest that a protocol based on this theory will result in a technology that is appropriate to the user, and as a result will be less likely to be abandoned and will contribute to goal achievement and potentially improve participation.

The incidence of differentiated thyroid cancer (DTC) is rising, but controversy exists in many aspects of its treatment. This study described the change in incidence of DTC in Ontario, variations in management including extent of thyroidectomy and the influence of provider volume, and the impact of these parameters on recurrence and thyroid cancer-specific death (TCSD). A population-based study identified all new cases of DTC between 1992-2007. The incidence of DTC increased dramatically (annual percentage change 7.6%). Linkage to administrative databases revealed that extent of thyroidectomy is influenced by various factors including patient gender, age, year of diagnosis, surgeon specialty, and hospital setting, but not provider volume. Total thyroidectomy is associated with a lower recurrence rate. There is a significant association between provider volume and recurrence, with lower volume surgeons having a higher recurrence risk. Extent of thyroidectomy and provider volume did not influence TCSD. Such variations in management may lead to disparities in health outcomes.
