Abstract

An increasing number of studies have documented the cognitive profile of individuals with mild cognitive impairment (MCI), but few studies have investigated the individuals’ psychological health and personality traits or how these factors interact with cognition. In the present study, 27 healthy older adults and 30 persons with MCI completed questionnaires covering psychological health, morale, personality, self-efficacy, and self-actualization. The results indicated that individuals with MCI are more depressed, anxious, hostile, and have lower morale than matched healthy older adults. Furthermore, our results show a positive association between the level of depression of MCI persons and the severity of their cognitive dysfunctions. In contrast, there were no group differences on measures of personality traits. Thus, while psychological distress is present in persons with MCI, those individuals are not characterized by differences in personality traits relative to older adults who experience no cognitive impairment.

Résumé

Plusieurs études ont documenté le profil cognitif des individus ayant un trouble cognitif léger (TCL), mais très peu se sont intéressées à leur santé psychologique et à leurs traits de personnalité ainsi qu’aux interactions entre ces facteurs et la cognition. Dans cette étude, 27 personnes âgées saines et 30 personnes ayant un TCL ont été soumises à une évaluation neuropsychologique et ont rempli des questionnaires portant sur la santé psychologique, le bien-être, la personnalité, l’auto-efficacité et l’auto-actualisation. Les résultats indiquent que les individus ayant un TCL sont plus déprimés, anxieux, hostiles et ont moins de bien-être que ce que rapporte un groupe de personnes âgées sans trouble de cognition. De plus, nos résultats révèlent une association positive entre le niveau de dépression des personnes ayant un TCL et la sévérité de leurs atteintes cognitives. En revanche, aucune différence n’est observée entre les groupes sur les échelles de personnalité. Ainsi, alors que la détresse psychologique est présente chez les personnes ayant un TCL, celles-ci ne montrent pas de différence de traits de personnalité par rapport aux personnes âgées n’éprouvant pas de troubles cognitifs.
