Despite the fairly widespread adoption of the 10-item Purdue Pharmacist Directive Guidance Scale (PPDG) over the last decade, only one study has assessed its psychometric properties. The present study examined the validity and reliability of the scale in a sample of 99 diabetic patients in the Southwestern United States. Principal axis factor analysis with Varimax rotation yielded two factors, "Instruction" and "Feedback and Goal Setting," similar to those found when the scale was originally developed. Cronbach's alphas for the total scale and the two factors were 0.95, 0.95, and 0.92, respectively. The scale and the two factors correlated significantly and positively with number of visits by patients to the pharmacist in the past 3 mo. These results provide further evidence for the internal consistency, and construct and criterion-related validities of the scale.

Background And Objectives: Telemedicine has become a mainstay of ALS clinical care, but there is currently no standardized approach for assessing and tracking changes to the neurologic examination in this format. The goal of this study was to create a standardized telemedicine-based motor examination scale to objectively and reliably track ALS progression and use Rasch methodology to validate the scale and improve its psychometric properties.

Methods: A draft telemedicine examination scale with 25 items assessing movement in the bulbar muscles, neck, trunk, and extremities was created by an ALS expert panel, incorporating input from patient advisors.

Measuring implicit associations with behaviours to improve resident mood: development of implicit association tasks for nursing home care providers.

Department of Primary and Community Care, Radboud University Medical Center, Research Institute for Medical Innovation, Radboudumc Alzheimer Center, Geert Grooteplein 21, 6525 EZ Nijmegen, the Netherlands.

Objective: To develop and evaluate instruments for measuring implicit associations of nursing home care providers with behaviours aimed at improving resident mood.

Method: Study 1 ( = 41) followed an iterative approach to develop two implicit association tasks measuring implicit attitude (positive versus negative valence) and motivation (wanting versus not wanting) regarding mood-improving behaviours, followed by an evaluation of the content validity for target stimuli representing these behaviours. In Study 2 ( = 230), the tasks were assessed for stimulus classification ease (accuracy and speed) and internal consistency.

Background: The ultimate goal of arthroplasty is thought to be the ability to "forget" a joint implant in daily activities. The Forgotten Joint Score (FJS-12), a score system that evaluates how much patients have been able to forget their hip or knee prosthesis, was recently published. It is based on a self-administered questionnaire that consists of 12 items.

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Utility - Core 10 Dimensions (QLU-C10D) adds a preference-based scoring algorithm to the EORTC measurement portfolio. It is built on the most widely used health-related quality of life (HRQoL) measure in oncology, the EORTC Quality of Life Questionnaire - Core 30 (QLQ-C30), allowing for the calculation of both HRQoL profiles and health utilities. This is an important advancement for integrating cancer-specific values into health economic evaluations and decision making, offering greater content validity and statistical power than some generic measures.
