OBJECTIVE This report examined limitations in our ability to assess clinically significant change (CSC) in randomized controlled trials of treatments of self-reported pediatric chronic pain intensity. METHODS The following were reviewed: (a) approaches to assessing CSC; (b) approaches to assessing CSC used in psychological treatment studies of self-reported pediatric chronic pain intensity in...

BACKGROUND The objective was to determine the test-retest reliability and criterion validity of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD). METHODS Forty-five non-wheelchair dependent subjects were recruited from three Dutch rehabilitation centers. Subjects' diagnoses were: stroke, spinal cord injury, whiplash, and neurological-, orthopedic- or back disord...

OBJECTIVES The aims were to characterize the movements in cervical dystonia (CD) by using an estimate of the mechanical power and work involved in the movements and to describe this through a movement energy index (MEI). MATERIALS AND METHODS The subjects (patients n = 6, controls n = 6) were seated in front of a screen with a laser pointer attached to a headband while they performed standard...

Purpose: The purpose of this study is to assess digital eye strain (DES) with the help scoring index (DESSI) in urban population. Methods: subjects were carefully selected no ocular or systemic problems that may alter results and prior written consent was obtained. This divided into two phases. Phase 1 consists reliability testing Cronbach’s alpha test-retest while phase 2 validity internal val...

Great advances have been made in functional Magnetic Resonance Imaging (fMRI) studies, including the use of longitudinal design to more accurately identify changes in brain development across childhood and adolescence. While longitudinal fMRI studies are necessary for our understanding of typical and atypical patterns of brain development, the variability observed in fMRI blood-oxygen-level dep...

We examined in a group of 15-year-old adolescents the retest reliability over one week of 7 subscales of the Automated Neuropsychological Metrics (ANAM), a computerized battery based on standard neuropsychological test measures that is one of several such batteries available to assess concussion effects. Since the principle behind these computerized batteries is to assess athletes before injury...

Relationships between adults and parents are characterized by positive and negative qualities. Existing measures of relationship qualities and ambivalence often rely on items that are unbalanced in number of positive and negative items, emotional tone, or missing negative items completely. Three studies established validity (construct, convergent, discriminant) and reliability (internal consist...

OBJECTIVE We examined the test-retest reliability and internal consistency of the Sensory Profile Caregiver Questionnaire (SP). METHOD Fifty-five primary caregivers of children 36-72 mo old participated in the study. Participants completed the SP on two separate occasions 7-14 days apart. Participant data were analyzed using intraclass correlation coefficients (ICCs) and Cronbach's α coeffici...

Magnetic resonance imaging (MRI) was used to evaluate within-subject variability in global mean cortical thickness over test-retest intervals of minutes-weeks in five healthy adults. Within-subject measures of global mean thickness were consistent over these intervals. Test-retest assessments of absolute thickness differences and percent thickness differences indicated variations of, respective...

Regression testing is a necessary but expensive maintenance activity aimed at showing that code has not been adversely a ected by changes. A selective approach to regression testing reuses tests from an existing test suite to test a modi ed program. Many selective retest strategies have been proposed. However, it is di cult to compare and evaluate these strategies, because they are based on di ...
