The Stroop Test is a quick and frequently used measure in screening for brain damage, dysfunction of selective attention, and cognitive flexibility. The purpose of the present study is to provide normative data for Trenerry's Stroop Neuropsychological Screening Test (SNST) in a sample of 605 healthy Greek participants (age range: 18-84 years, education range: 6-18 years). Results revealed that age and education significantly contributed to SNST scores, accounting for a significant proportion of variance in time needed to complete the color task and in the interference Color-Word score. Performance on most of the measures decreases with increasing age and lower levels of education. Normative data stratified by age and education for the Greek adult population are provided as a useful set of norms for clinical practice.

BackgroundPatients suffering from several neurologic disorders may bear the “stigma” of their disease, being disqualified from full social acceptance. Although stigma is considered to be present in Multiple Sclerosis (MS), the factors that influence its levels are ambiguous. Aim of our study was to examine, for the first time in the literature, the basic determinants of stigma in a Hellenic MS-patients cohort, as well as how stigma affects their Quality-of-Life (QoL) profiles.MethodsThree hundred forty two patients were recruited in this study. Data collected concerned sociodemographic and disease-related variables, mental illness assessment, Multiple-Sclerosis-QoL-54 (MSQoL-54) and Stigma-Scale-for-Chronic-Illness-24 (SSCI-24) questionnaires. Potential determinants were evaluated with univariate statistical analyses for their contribution to total, internalized (inner-self derived) and externalized (society derived) stigma. Important findings were further evaluated on hierarchical regression models.ResultsDisability levels were found to be the most powerful predictor in all stigma categories, followed by the presence of mental illness. Working and caregiving status were also ascertained as determinants of internalized stigma. Stigma levels displayed strong negative correlation with all composites of MSQoL-54.ConclusionsStigma is present in the social environment of MS patients and was confirmed as a barrier (according to the International Classification of Functioning, Disability and Health), with detrimental effects on their QoL levels and functioning performances. Disability and mental illness were shown as the principal determinants of stigma, while financial characteristics were not as equally involved. Further validation of these results in other MS populations may provide safer conclusions, towards more efficacious patient-centered care outcomes.
