The purpose of this study was to illustrate the prevalence of statistically reliable change scores on memory test batteries in healthy adults and older adults. METHOD Participants included three adult and older adult...

AIMS Reliabilities of the work environment questionnaire Copenhagen Psychosocial Questionnaire (COPSOQ) have previously been estimated by Cronbach's alpha, but since the internal consistency assumption may not apply to all COPSOQ scales, Cronbach's alpha may underestimate true reliability. This study aims to evaluate reliability in a test-retest design. METHODS We analyzed postal questionnair...
