“…One point was scored for each attribute assignment consistent with the predefined profile (maximum score 42=6x7). Although task reliability improves with number of items [29], we had to restrict it to 6 items for time-economic reasons (olfactory tasks being only a fraction of the GRAS examination procedure [26]).…”

BackgroundOlfactory function tests are sensitive tools for assessing sensory-cognitive processing in schizophrenia. However, associations of central olfactory measures with clinical outcome parameters have not been simultaneously studied in large samples of schizophrenia patients.MethodsIn the framework of the comprehensive phenotyping of the GRAS (Göttingen Research Association for Schizophrenia) cohort, we modified and extended existing odor naming (active memory retrieval) and interpretation (attribute assignment) tasks to evaluate them in 881 schizophrenia patients and 102 healthy controls matched for age, gender and smoking behavior. Associations with emotional processing, neuropsychological test performance and disease outcome were studied.ResultsSchizophrenia patients underperformed controls in both olfactory tasks. Odor naming deficits were primarily associated with compromised cognition, interpretation deficits with positive symptom severity and general alertness. Contrasting schizophrenia extreme performers of odor interpretation (best versus worst percentile; N=88 each) and healthy individuals (N=102) underscores the obvious relationship between impaired odor interpretation and psychopathology, cognitive dysfunctioning, and emotional processing (all p<0.004).ConclusionsThe strong association of performance in higher olfactory measures, odor naming and interpretation, with lead symptoms of schizophrenia and determinants of disease severity highlights their clinical and scientific significance. Based on the results obtained here in an exploratory fashion in a large patient sample, the development of an easy-to-use clinical test with improved psychometric properties may be encouraged.

“…Third, item deletion is likely to mean that the test under-represents certain cognitive domains, compromising the factorial structure of the screening tool and reducing sensitivity to dimensions of cognition characteristically impaired in certain types of dementia. Last, there is potential for item deletions to negatively impact re-test reliability (Symonds, 1928).…”

While attempts have been made to adapt cognitive tests for people with acquired hearing and/or vision impairment, the primary limitation of these adaptations is that their validity in accurately detecting dementia among those with acquired hearing or vision impairment is yet to be established. It is likely that the sensitivity and specificity of the adapted versions are poorer than the original, especially if the adaptation involved item deletion. One solution would involve item substitution in an alternative sensory modality followed by re-validation of the adapted test.

“…Data collection was carried out in two stages, one prior to the application of the program intervention (test) and another after the intervention finished. To carry out the data registration, we analyzed the determining factors (illness, excitement, accidents during assessment [ 31 ]) that should be taken into account to ensure the reliability of the tests. This procedure of analysis and control of the determining factors was carried out with the objective of not affecting the variables by using the same conditions in all cases.…”

This study aimed to investigate the influence of a structured movement activity program on the motor development of children aged three to five years attending preschool. Participants were 136 preschool students with normative development at three to four years old who lived in the Region of Murcia (Spain). The McCarthy Children’s Psychomotricity and Aptitude Scales (MSCA) battery of psychomotor tests was used to evaluate the motor development profiles of preschoolers before and after the intervention. The sample was divided into two groups: an intervention group (28 students) and a comparison group (108 students). A structured 24 week physical education program was used in the intervention group. An experiential program based on free play was used in the comparison group during the same period. Preschoolers in both groups got a significant improvement in the contrast of pre-intervention with post-intervention in limb coordination. Statistically significant differences in the post-intervention measurements between the comparison group and the intervention group on arm and leg coordination were observed, whereby the intervention group presented higher arm coordination values (F1,134 = 14,389, p = 0.000, η2 = 0.097) and higher leg coordination values (F1,134 = 19,281, p = 0.000, η2 = 0.126) than the comparison group. It was pointed out that structured physical activity education is better educational methodology than free play to achieve adequate motor development in preschool children.
