PURPOSE Standard automated perimetry (SAP) shows a marked increase in variability in damaged areas of the visual field. This study was conducted to test the hypothesis that larger stimuli are associated with more uniform variability, by investigating the retest variability of four perimetry tests: standard automated perimetry size III (SAP III), with the SITA standard strategy; SAP size V (SAP ...

Objective Reliable and valid needs assessment measures are important assessment tools in cancer survivorship care. A new 30-item short-form version of the Survivor Unmet Needs Survey (SF-SUNS) was developed and validated with cancer survivors, including hematology cancer survivors; however, test-retest reliability has not been established. The objective of this study was to assess the test-rete...

UNLABELLED PET can be used to monitor response during chemotherapy and assess biologic target volumes for radiotherapy. Previous simulation studies have shown that the performance of various automatic or semiautomatic tumor delineation methods depends on image characteristics. The purpose of this study was to assess test-retest variability of tumor delineation methods, with emphasis on the effe...

Studies of test-retest reliability for health-related quality of life instruments have used varying intervals between test administrations. There is no evidence available to aid in the selection of the time interval between questionnaire administrations for a study of test-retest reliability for health status instruments. We compared the test-retest reliability at 2 days and 2 weeks for four kn...

Investigation of the short-term (90-day) stability of the Adjustment Scales for Children and Adolescents is reported for 124 randomly selected children in grades ranging from kindergarten to grade 12. Significant test-retest stability coefficients were obtained and mean differences across the retest interval did not exceed .8 raw score points. The Solitary Aggressive-Impulsive, Diffident, and L...

Background. The NeuroTrax Mindstreams computerized cognitive assessment system was designed for widespread clinical and research use. A requirement for its use in longitudinal testing is demonstration of good test-retest reliability. To minimize practice effects, alternate forms of Mindstreams tests were administered on serial testing sessions. The present study evaluated the equivalence of the...

Context: Athletes are often examined for return to sports using a functional-testing algorithm. No research has determined whether a closed kinetic chain (CKC) isokinetic testing bout influences the reliability of functional tests. Objective: To determine whether a concentric CKC isokinetic test bout alters test–retest reliability of lower extremity functional testing. Design: Subjects particip...

Mixed effects models were used to examine the separate effects associated with age and retest on changes in various cognitive abilities. Individuals (N > 800) ranging in age from 40 to 70 years at the 1st measurement occasion were assessed with measures of memory, spatial abilities, and speed on 4 occasions. All cognitive abilities showed decline associated with increased age and improvement ac...

OBJECTIVE The purpose of this study is to establish the test-retest reliability of the Child-Initiated Pretend Play Assessment (ChIPPA) (Stagnitti, 2002a; Stagnitti, Unsworth, & Rodger, 2000). METHOD The first author rated 38 preschool children ages 4 and 5 years (4 with developmental delay and 34 typically developing) on the ChIPPA. The ChIPPA employs conventional play materials and unstruct...

Published protocols for the volumetric assessment of upper-extremity edema differ regarding patients' posture. The present study was designed to determine the effect of posture on test-retest reliability and mean volume. Thirty women were tested in both seated and standing postures. For the dominant hand, test-retest reliabilities for the seated posture were identical to those for the standing ...
