The MoCA has proved to be an appropriate measure for cognitive screening taking into account different cognitive domains, which will enable clinicians and researchers to use this test and its six latent dimensions to achieve a better understanding of the individuals’ cognitive profile. Title: The Montreal Cognitive Assessment (MoCA) as a screening test for cognitive dysfunction in Multiple Sclerosis. The present findings corroborate the six-dimensional structure of the MoCA and provide good evidence of the construct related validity. This study contributes to overcome an important gap in the construct related validity of this instrument. An overall psychometric adequacy of the items, and a good reliability were also found. The Montreal Cognitive Assessment (MoCA) was developed by Dr Ziad Nasreddine in Montreal, Canada in 1995 for the detection of mild cognitive impairment (MCI) by health professionals. The results allowed us to establish the factorial, convergent, and discriminant validity of this six-dimensional structure.
Although all tested models showed a good fit, the six-factor model based on the conceptual model proposed by the MoCA's authors showed a significantly better fit. There is a lack of consensual tools for evaluating the cognitive side-effects in patients with depression who are treated with electroconvulsive therapy (ECT). In a Portuguese sample of 830 participants, several models were tested using Confirmatory Factor Analysis. 2 The MoCA takes approximately 20 minutes to administer and has a maximum score of 30, with lower scores representing poorer performance.
The present study aims to assess the construct related validity of the MoCA through the establishment of the factorial, convergent, and discriminant related validities, and the reliability of data. Montreal Cognitive Assessment (MoCA) The MoCA is a screening test assessing global cognitive function that assesses memory, visuospatial ability, executive function, attention, concentration, working memory and orientation. The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment.
