Our study showed that the FAB may be an adequate assessment tool for executive function and may provide useful information for differential diagnosis in several diseases. Given that the FAB takes short time and is easy to administer, its usage may be of great interest as part of a full neuropsychological assessment in clinical settings.

BackgroundDeficits in executive functions (EFs) are frequently detected in patients with Parkinson’s disease (PD). The Frontal Assessment Battery (FAB) is a screening test for assessing EFs although it has not been so far adapted and validated in Spain. We evaluated the reliability and validity of the Spanish version of the FAB (FAB-E) in PD patients.Materials and methodsOur study included 54 healthy subjects and 67 PD patients. Cognitive assessment of participants was conducted using the FAB-E, Mini-Mental State Examination (MMSE), Trail Making Test (TMT), Revised-Barcelona Test (RBT) and Executive Interview (EXIT-25). Internal consistency, intra- and test-retest reliabilities, concurrent and discriminant validity of the FAB-E were examined. To evaluate the influence of cognitive dysfunction in PD on the performance of the FAB-E, we also classified the PD patients into groups according to their cognitive status as measured by the MMSE using published criteria to identify cognitive deficits in PD.ResultsThe FAB-E showed good internal consistency (α = 0.751). The intraclass correlation coefficients (ranging from 0.559 to 0.891) and Spearman correlations (from 0.494 to 0.864) of the FAB-E subtests indicated a good-strong reliability. The total and subtest scores generally showed a good concurrent validity, except for the prehension behaviour item of the FAB-E and the Interference and Go/no-go tasks of the EXIT-25 that presented low estimates. Excluding the prehension behaviour subtest, the performance of the FAB-E was higher in the control group than in PD patients. Cognitive dysfunction in PD patients also indicated significant poorer FAB-E scores excepting the motor and prehension behaviour subtests. Discriminant analysis determined a cut-off of 14.5 was optimal to differentiate healthy subjects from PD patients. Moreover, a cut-off <12.5 allocated satisfactorily those PD patients with cognitive impairment (MMSE<26) and scores <11.5 classified suitably those PD patients with dementia (MMSE<24).ConclusionThe FAB-E is an accurate tool for evaluating EFs in patients with PD and can provide useful information for distinguishing PD patients with and without cognitive dysfunction at a bedside assessment.

Background The Occupational Balance Questionnaire (OBQ) is an instrument that assesses occupational balance (OB). It has been transculturality adapted and validated in different countries, showing adequate psychometric properties. To date, no general population-based cut-off points for OB have been developed. Objective To assess the psychometric proprieties of the Spanish version OBQ (OBQ-E) and to estimate reference norms and the cut-off for OBQ-E in a representative sample of Spanish adults. Materials and methods A total of 797 adults were included in this validity study. Internal consistency, intra and test-retest reliability of OBQ-E were examined. To obtain the convergent validity and the divergent validity, the Satisfaction with Life Scale (SLS) and the Hospital Anxiety and Depression Scale (HAD) were used respectively, compared with OBQ-E. To determine extreme and moderate disturbed OB stratified by age, sex, and educational level were used the 5 and 15% percentiles of OBQ-E. Results The OBQ-E showed good internal consistency ( α -Cronbach = 0.87), intraclass reliability (ICC = 0.87), and test-retest reliability (rho = 0.83). Convergent (SLS) and divergent (HAD) validity were moderate (rho = 0.39 and rho = −0.46, respectively). The lowest extreme disturbed OB cut-off point in men (17.2) and in women (24) appeared at the primary education level, under 40 years of age (men) and 40–65 years of age (women). Conclusions The OBQ-E presents adequate psychometric properties, and its normative data can be used as a reference to assess and monitor the occupational balance in the general Spanish population. KEY MESSAGES The ‘Occupational Balance Questionnaire’ (OBQ), stands out as a specific measure of the concept of Occupational Balance, considered as satisfaction with the number and variation of occupations in which the person participates. The OBQ is a short and simple instrument that can be a useful tool for use in population-based and epidemiological studies to monitor OB and explore the associated factors or implications of disturbed OB. The Spanish version of the OBQ (OBQ-E) seems to be a reliable and valid questionnaire to assess the perception of balance between occupations, related to health and well-being in the Spanish adult population.

We assessed the association between adherence to the Mediterranean diet (MD) and sensory processing in 583 Spanish children aged 3–7 years from the InProS project in Alicante, Spain. Child sensory processing was measured using the short sensory profile (SSP); atypical sensory performance was defined as SSP total score <155; tactile sensitivity <30; taste/smell sensitivity <15; movement sensitivity <13; under-responsive/seeks sensation <27; auditory filtering <23; low energy/weak <26; and visual/auditory sensitivity <19 scores. Adherence to the MD was measured using the Mediterranean diet quality index KIDMED. Multiple Poisson regression models with robust variance, based on the Huber sandwich estimate, were used to obtain prevalence ratios (PR). Our findings suggested that a lower prevalence of atypical tactile and taste/smell sensitivity were associated with having medium (PR = 0.50, 95% CI: 0.25; 0.99; PR = 0.57, 95% CI: 0.33; 0.99, respectively) and high adherence to the MD (PR = 0.58, 95% CI: 0.34; 0.99; PR = 0.33, 95% CI: 0.19; 0.60, respectively), and of atypical low energy/weak with having medium adherence to the MD (PR = 0.37, 95% CI: 0.16; 0.83). A two-point increase in adherence to the MD showed a general positive effect against atypical sensory performance, although it was statistically significant on taste/smell sensitivity (PR = 0.71, 95% CI: 0.59; 0.85) and low energy/weak (PR = 0.80, 95% CI: 0.64; 0.99) subscales. To our knowledge, this is the first study that shows a protective effect of adherence to the MD against prevalence of atypical sensory processing in school-aged children. Further research from longitudinal studies is required to confirm these findings.

Objective: The aim of this study is to examine the psychometric properties of the Spanish version of the Oxford Cognitive Screen in a subacute stroke population. Participants and setting: Fifty-seven subacute stroke outpatients and 54 healthy individuals were recruited in Alicante province, Spain. Main measure: The Oxford Cognitive Screen. Other measures: The Montreal Cognitive Assessment, the Barcelona test, and the Barthel Index. Design: A validation study was conducted to analyze the inter-rater, intra-rater, test–retest, and internal consistency of the Spanish version of the Oxford Cognitive Screen. Concurrent validity was assessed using the Montreal Cognitive Assessment and the Barcelona test, and divergent validity using the Barthel index. Discriminant indices such as the sensitivity, specificity, predictive values, and optimal cut-offs were also estimated. Results: The subtests of the Spanish version of the Oxford Cognitive Screen showed excellent estimates for the inter-reliability (intraclass correlation coefficient (ICC) = 0.790 to 1.000; rs = 0.693 to 1.000), and acceptable-good for intra-reliability (ICC = 0.181 to 0.990) and test–retest reliability (rs = 0.173 to 0.971). Internal consistency was also excellent (standardized Cronbach’s α = 0.907). Spearman correlations for the concurrent validity were low-strong (rs = −0.193 to 0.95) and low-moderate (rs = −0.091 to 0.443) for divergent validity. The optimal cut-offs estimated for the subtests of the Spanish version of the Oxford Cognitive Screen showed good-high specificity (66.7%–100%) and positive predictive value (67.9%–100%), and low-good sensitivity (14.8%–83.3%) and moderate-good negative predictive value (53.5%–76.6%). Discriminant power as measured by the area under the curve indicated acceptable-good values (0.397 to 0.894). Conclusion: Our findings support that the Spanish version of the Oxford Cognitive Screen is a reliable and valid tool for screening cognitive impairments in subacute stroke patients.
