Although longitudinal designs are the only way in which age changes can be directly observed, a recurrent criticism involves to what extent retest effects may downwardly bias estimates of true age-related cognitive change. Considerable attention has been given to the problem of retest effects within mixed effects models that include separate parameters for longitudinal change over time (usually...

OBJECTIVE Our aim was to validate an international instrument measuring self-perceived competency level of family physicians in Albania. METHODS A representative sample of 57 family physicians operating in primary health care services was interviewed twice in March-April 2012 in Tirana (26 men and 31 women; median age: 46 years, inter-quartile range: 38-56 years). A structured questionnaire w...

PURPOSE To determine whether sensitivity estimates from an individual's previous visual field tests can be incorporated into perimetric procedures to improve accuracy and reduce test-retest variability at subsequent visits. METHODS Computer simulation was used to determine the error, distribution of errors and presentation count for a series of perimetric algorithms. Baseline procedures were ...

This study examined whether the nonitem-specific retest learning effects, previously shown with young-old adults primarily in their 60s and 70s, could be extended to oldest-old adults aged 80 and onward. Twenty-one oldest-olds participated in an 8-session retest training program with three ability domains: perceptual speed, inductive reasoning, and visual attention. Their data were compared wit...

The present study examined whether a nap after complex motor learning enhanced the following day's physical performance. Eighteen volunteers met the inclusion criteria and were assigned to either a nap (n=9; men=5; mean age=21.0±1.5) or no-nap group (n=9; men=5; mean age=21.9±0.3). Participants practiced juggling in the morning and were tested immediately afterwards. Participants of the nap gro...

Nonsuicidal self-injury (NSSI) is a growing public health problem among adolescents and young adults. The Inventory of Statements About Self-Injury (ISAS) is a self-report measure designed to assess NSSI behaviors and functions. The current study examines the one-year test-retest reliability of the ISAS in a sample of young adult self-injurers. Results indicate that the ISAS behavioral and func...

Introduction Law 12.303/10 requires hearing screening in newborns before hospital discharge to detect possible hearing problems within the first three months after birth. If the newborn fails the test or presents signs of risk for hearing loss, it must undergo a retest and monitoring during the first year of life. In practice, this often does not happen. Objective To identify, in a group of mot...

This study examined the maintenance of retest learning benefits in young old and oldest old adults over an 8-month period in 3 cognitive abilities: reasoning, perceptual-motor speed, and visual attention. Twenty-four young old (aged 70-79 years, M = 74.2) and 23 oldest old adults (aged 80-90 years, M = 83.6) who participated in a previously published study (Yang, L., Krampe, R. T., & Baltes, P....

This study aimed to investigate the test-retest reliability of a Mandarin Chinese version of the Childhood Autism Spectrum Test (CAST), in a Chinese population. Parents in a school based study on the prevalence of ASC in mainland China were asked to complete a second version of the CAST approximately 2-4 months after first completion. Test retest data were available from 70 children (questionna...
