Objective Previous research has shown that cognitive tests can lead to misclassification when applying non-representative norms to measure cognitive performance. The objective of this study was to investigate whether this misclassification also occurs with a non-verbal so-called “culture-free” intelligence test administered to different age groups. Method The intelligence of a sample of healthy Moroccan children (N = 147) ages 7, 9, and 11 was assessed using the Coloured Raven’s Progressive Matrices (CPM). Raw scores were used to study age differences, as well as misclassifications when applying the norms of three countries culturally different from Morocco (United Kingdom, Spain, and Oman). Results Intelligence performance was not within the normal range when non-representative norms were applied to the Moroccan raw scores. Misclassifications accounted for a large percentage of the participants that supposedly displayed intelligence deficits, especially when applying the British norms. Up to 15.68% of the healthy children fell within the “intellectually impaired” range, and up to 62.5% fell “below average,” with these percentages especially higher at older ages. Conclusions Our findings confirm that “culture-free” tests should be adapted to each culture and applied together with their culture’s specific norms to prevent misclassification and allow for a better, unbiased neuropsychological assessment.

Objective : The aim was to develop and establish the psychometric properties of the Pandemic-Related Pregnancy Stress Scale (PREPS) in European Spanish speaking pregnant women in Spain. Design : A cross section design using a non-random sample of 206 women completed the questionnaire during the first COVID-19 pandemic lockdown from April to June 2020 in Spain. Psychological, sociodemographic and obstetric factors and the new PREPS were collected. Results : Bartlett's test of sphericity (χ 2 (105) = 580.36, p < .001), and KMO = .79 confirmed appropriateness for factor analysis of the PREPS. Confirmatory factor analyses based on the factor structure of the original USA English version of this instrument confirmed three factors - Preparedness Stress (7 items), Perinatal Infection Stress (5 items), and Positive Appraisal (3 items). The 15-item version of the PREPS demonstrates internal consistency and reliability are adequate (α > .77), and for F1 - Preparedness (α > .65), for F2 - Infection (α > 0.60) and for F3 - Positive appraisal (α > .55). The three factors exhibited good inter-item correlations, (F1 – Preparedness: .21; F2 – Infection: .23, and F3 – Positive Appraisal: .29). Convergent validity was examined through the Pearson's correlation coefficients of the PREPS with the Perceived Stress Scale (PSS) and the Prenatal Distress Questionnaire (PDQ). Correlation between PREPS total and PSS was high, and moderate with PDQ (p < .05). Conclusion : The psychometric properties of the Spanish version of the PREPS make it a valuable psychological measure to assess pandemic-related stress among pregnant women.

Objective The continuous performance tests (CPTs) are the gold standard to assess vigilance or sustained attention. Many studies have shown that educational level is significantly associated with performance on the CPTs. However, very few studies have made comparisons that included cultural factors (Miranda et al, 2008). Given the breadth of educational systems in different parts of the world, it could be expected that the effect of educational level will vary depending on the culture of origin. The aim of this study was to examine the effect of education on performance on a CPT task in 3 ethnically diverse groups (Hispanic, Non-Hispanic and Spanish). Participants and Method This study includes 57 participants in the EMBRACED project: 12 Hispanic Americans, 26 non-Hispanics Americans, and 19 Spaniards (8.3%, 30% and 57% with high education respectively). Educational level was defined as high (university degree and above) or low (less than a university degree). The EMBRACED CPT is computerized and demands the participant to touch the iPad screen each time a target is presented. In 3 blocks of 100 stimuli each, the number of hits, omissions, and commissions is recorded. Results A mixed between-within subjects analysis of variance was conducted to compare scores in the three blocks of the CPT in relation to the three cultural groups and by education levels. Results showed no interaction effects between cultural groups and education, and no main effects of education for any of the studied variables. However, there was a significant main effect for cultural group for hits (F = 4.676, P = .014) and omissions (F = 5.614, p = .006). Conclusions The overall results for education in this study were not significant and would need further study. The variability in cultural group revealed a consistent effect across all studied variables. The non-Hispanics scored higher in hits and the Spaniards had more omissions. These results justify the need for cultural adaptation of neuropsychological measures. References Miranda, M. C., Sinnes, E. G., Pompeia, S., & Francisco Amodeo Bueno, O. (2008).
