The use of the coefficient of variation in detecting sincerity of effort: a meta-analysis.

The coefficient of variation (CV) is used to determine sincerity of effort of strength measurements. However, there is a controversy in the literature concerning its validity and effectiveness. We used a meta-analytic approach and calculated the effect size between maximal and submaximal efforts for the CV of grip, elbow flexion and knee extension.

Does lung transplantation improve health-related quality of life? The University of Florida experience.

Background: Health-related quality of life (HRQoL) is an important clinical end-point in evaluating the overall success of lung transplantation. The primary purpose of this study, therefore, was to document the degree of change in HRQoL in a sample of patients evaluated before and after lung transplantation.

Methods: Sixty-six adults who underwent single or bilateral lung transplantation at the University of Florida between March 1994 and May 2001 completed assessments of HRQoL (SF-36 Health Survey, Transplant Symptom Frequency Questionnaire), both before and after transplant.

Are organ donation attitudes and beliefs, empathy, and life orientation related to donor registration status?

Context: The severe organ donor shortage necessitates additional research on variables that may distinguish those who register to be organ donors and those who do not. Such research has important implications for the development of educational interventions.

Objective: To examine whether registered organ donors differ significantly from nondonors on measures of organ donation beliefs and attitudes, empathy, and life orientation.

Adherence to exercise prescriptions: effects of prescribing moderate versus higher levels of intensity and frequency.

Sedentary adults (N = 379) were randomly assigned in a 2 x 2 design to walk 30 min per day at a frequency of either 3-4 or 5-7 days per week, at an intensity of either 45%-55% or 65%-75% of maximum heart rate reserve. Analyses of exercise accumulated over 6 months showed greater amounts completed in the higher frequency (p = .0001) and moderate intensity (p = .

Impact of body weight on long-term survival after lung transplantation.

Study Objectives: The purpose of this study was to determine the impact of a pretransplantation determination of body mass index (BMI) on survival after lung transplantation.

Design And Patients: Univariate and multivariate survival analyses of a single institution database consisting of 85 patients who had undergone lung transplantations between March 1994 and October 1998.

Setting: University of Florida Health Science Center.
