ABSTRACT The decline in frontal cognitive functions contributes to alterations of gait and increases the risk of falls in patients with dementia, a category which included Alzheimer's disease (AD). The objective of the present study was to compare the gait parameters and the risk of falls among patients at different stages of AD, and to relate these variables with cognitive functions. This is a cross-sectional study with 23 patients with mild and moderate AD. The Clinical Dementia Rating was used to classify the dementia severity. The kinematic parameters of gait (cadence, stride length, and stride speed) were analyzed under two conditions: (a) single task (free gait) and (b) dual task (walking and counting down). The risk of falls was evaluated using the Timed Up-and-Go test. The frontal cognitive functions were evaluated using the Frontal Assessment Battery (FAB), the Clock Drawing Test (CDT) and the Symbol Search Subtest. The patients who were at the moderate stage suffered reduced performance in their stride length and stride speed in the single task and had made more counting errors in the dual task and still had a higher fall risk. Both the mild and the moderate patients exhibited significant decreases in stride length, stride speed and cadence in the dual task. Was detected a significant correlation between CDT, FAB, and stride speed in the dual task condition. We also found a significant correlation between subtest Similarities, FAB and cadence in the dual task condition. The dual task produced changes in the kinematic parameters of gait for the mild and moderate AD patients and the gait alterations are related to frontal cognitive functions, particularly executive functions. 相似文献

The Experiences in Close Relationships–Relationship Structures questionnaire (ECR–RS) is one of the most recent measures of adult attachment. This instrument provides a contextual assessment of attachment-related anxiety and avoidance by measuring these dimensions in various close relationships (mother, father, partner, friend). To further explore its psychometric properties and cross-cultural adequacy, this study presents the validation of the ECR–RS in a sample of Portuguese community individuals (N = 236). The Portuguese version showed adequate reliability and construct validity. The original 2-factor structure was confirmed through confirmatory factor analysis. The ECR–RS is a psychometrically robust measure of attachment, representing an important advance in the measurement of adult attachment. 相似文献

This research summarizes the knowledge generated in social psychology and positive psychology about the relationship between humor styles, personality and wellbeing. Specifically, a meta‐analysis was performed with the results of 15 studies on humor styles measured by the Humor Styles Questionnaire (Martin, Puhlik‐Doris, Larsen, Gray & Weir, 2003) in correlation with the personality traits measured by the Big Five Personality model (measured with different scales). Following the steps presented by Rosenthal (1991) for meta‐analysis in the case of correlational research, we calculated the total mean r as an indicator of effect size. Results show that affiliative humor has a strong and homogeneous relation to neuroticism and extraversion. The homogeneity and heterogeneity found between variables and possible explanations are discussed in the conclusion. 相似文献

Loneliness is a subjective and emotionally unpleasant experience of perceiving insufficient social relationships. Previous research has revealed that loneliness constitutes a psychosocial risk factor for depression, and is also related to unhealthy behaviors such as smoking. This study aims to examine the relation between loneliness, depression, and cigarette dependence, and to explore the role of sex in this relationship. A total sample of 275 adult treatment-seeking daily smokers (Mage = 45.3; 61.5% females) was used. Our results showed a significant correlation between higher scores of loneliness, depressive symptoms, and cigarette dependence. In addition, mediation analysis showed a significant indirect effect of loneliness on cigarette dependence, via depressive symptoms. Regarding the effect of sex, we found that this variable significantly moderated the relationship between depressive symptoms and cigarette dependence. Results of this study extend previous literature by showing that, in treatment seeking smokers, loneliness is a significant predictor of depressive symptoms, and through this relation, it predicts cigarette dependence. Additionally, sex was a significant moderator of this relation. These findings have several clinical implications, and also contribute to the understanding of cigarette dependence, which is a well-known barrier for smoking cessation. 相似文献

Organizations often utilize empowerment as a way to bolster performance. It is largely assumed, however, that its impact in this capacity is equivalent across organizational members. We tested this notion within a sample of 420 employees belonging to 75 teams in a Chinese organization and found that team empowerment related positively to supervisor‐rated in‐role and self‐rated extra‐role performance through its effect on individual psychological empowerment. More important, employee–coworker demographic dissimilarity moderated both stages of this indirect relationship. Specifically, when employee–coworker sex dissimilarity was higher, the following relationships were attenuated: (a) team empowerment–individual empowerment, (b) individual empowerment–in‐role performance, and (c) individual empowerment–extra–role performance. Collectively, the results illustrate that the impact of empowerment is contingent upon demographic dissimilarity. 相似文献

At the behavioural level, the activity of a writer can be described as periods of typing separated by pauses. Although some studies have been concerned with the functions of pauses, few have investigated motor execution periods. Precise estimates of the distribution of writing processes, and their cognitive demands, across periods of typing and pauses are lacking. Furthermore, it is uncertain how typing skill affects these aspects of writing. We addressed these issues, selecting writers of low and high typing skill who performed dictation and composition tasks. The occurrences of writing processes were assessed through directed verbalization, and their cognitive demands were measured through interference in reaction times (IRT). Before writing a narrative, 34 undergraduates learned to categorize examples of introspective thoughts as different types of activities related to writing (planning, translating, or revising). Then, while writing, they responded to random auditory probes, and reported their ongoing activity according to the learned categories. Convergent with previous findings, translating was most often reported, and revising and planning had fewer occurrences. Translating was mostly activated during motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes can be characterized as being typical of pauses, since translating was activated to a similar extent as the other two processes. Regarding cognitive demands, revising is likely to be the most demanding process in narrative writing. Typing skill had an impact on IRTs of motor execution. The demands of execution were greater in the low than in the high typing skill group, but these greater demands did not affect the strategy of writing processes activation. Nevertheless, low typing skill had a detrimental impact on text quality. 相似文献

The aim of this study consists in the measurement of psychological health and adaptation in mothers of children during the first 12 months of treatment for leukaemia and in the identification of possible early predictors. Ninety-four mothers were followed longitudinally at one week (T1), one month (T2), six months (T3) and 12 months (T4) post-diagnosis. The instruments used were: PTSD symptom checklist, BSI-18, Problem Scale, Ladder of life and an in-depth interview (EFI-C). Couple connectedness, family routine reorganisation, parental communication around the child's illness and trust in the medical care significantly increased from T1 to T4. Two models are proposed concerning possible predictors of mothers’ PTSS at T2 and at T3. Clinical suggestions are proposed on the basis of our empirical findings in order to plan informative, clinical and practical interventions for mothers of children under treatment for leukaemia. 相似文献

Childhood gender identity development is reviewed in the context of biological, environmental, cultural, and diagnostic factors. With the upcoming 5th revision of the Diagnostic and Statistical Manual of Mental Disorders, the authors offer a critical consideration of childhood gender identity disorder, along with proposed diagnostic changes. They argue that meaningful understanding of issues surrounding gender identity is necessary for a conscientious assessment and diagnostic process that does not pathologize human diversity. 相似文献

The current article attempts to extend previous research by testing the effects of customer satisfaction and 2 types of switching barriers—negative and positive—on key manifestations of attitudinal loyalty (repurchase intentions, positive recommendations, and price tolerance). The work also studies whether the effect of customer satisfaction is linear or nonlinear. Finally, the paper analyzes whether switching barriers moderate the relative strength of the customer satisfaction/attitudinal loyalty relation. To this end, a total of 554 private mobile‐phone customers were surveyed. The distinction between negative and positive switching barriers is important to draw theoretical and managerial implications. 相似文献
