Differential effects of faces and words in cognitive control in older adults with and without major depressive disorder: An emotional Stroop task study.

Aging and major depressive disorders have been associated with impaired cognitive control. These deficits are also influenced by the affective valence and by the type of stimulus processed. Using an emotional Stroop task, the current study aims to examine cognitive control deficits and their association with emotion regulation in depression and the influence of the type of stimulus (words and faces) in this association. A total of 26 older patients with a major depressive disorder (MDD) (19 women; age range: 65-84 years) and 26 older healthy controls (18 women; age range: 65-80 years) participated in the study. The results showed that MDD individuals presented greater Stroop effects than their healthy controls and an absence of the conflict adaptation effect defined as a reduction of the influence of irrelevant stimulus dimensions after incongruent trials. Additionally, our results also showed that the processing of emotional words in depressed participants is more automatic than the processing of emotional faces. These findings suggest that older depressed individuals have greater difficulty in recognizing affective facial expressions than older healthy controls, while the over-learned behavior of word reading greatly reduces differences in the performance of the emotional Stroop task between groups (MDD and healthy controls).

Effects on intermittent postural control in people with Parkinson's due to a dual task.

OBJECTIVES: The aim of the present study was to determine the effects of performing a dual task on the sway density plot parameters in Parkinson's disease and control subjects. METHODS: A cross-sectional design was used to establish differences in the mean peak, mean time, and mean distance between a group with Parkinson's disease and a control group without Parkinson's disease. The subjects performed, in a unique measurement session, two trials under three different randomized conditions: i. eyes open, ii. eyes closed, and iii. Eyes open with foam base. One trial was performed as a single task (i.e., the subjects completed one of the balance test), while the other trial was performed as a dual task (i.e., the subjects performed a cognitive task at the same time that they maintained the static balance). RESULTS: There was a group x dual task x condition effect in mean peak (F1.5, 51.1 = 5.21; p = 0.015; η2p = 0.13) and mean time (F1.4, 47.3 = 4.43; p = 0.03; η2p = 0.11) variables. According dual-task cost analysis, there was a main effect of the condition (F6,134 = 2.44; p = 0.05; η2p = 0.34) on MD (F2,68 = 6.90; p < 0.01; η2p = 0.17). CONCLUSIONS: This result indicates differences in the dual task interference in the postural control mechanisms between the Parkinson's disease population and healthy pairs. For easy dual tasks, the Parkinson subjects used anticipatory control responses for longer periods of time, and for more difficult tasks, their control strategy did not change regarding single balance task.

Effectiveness of instrumental reminiscence intervention on improving coping in healthy older adults.

Reminiscence is a psychological intervention that uses the recall of past events, feelings, and thoughts to facilitate pleasure, quality of life, and adjustment to present life. The main goal of this study was to investigate the effect of a reminiscence intervention programme on coping strategies. One hundred fifty healthy older adults attended the reminiscence sessions. In order to evaluate the effects of the programme and find out if its effects lasted over time, we used an experimental design with pretest, posttest, and follow-up assessments, comparing a control group to the intervention group. Repeated-measures analysis of variance showed significant differences in problem-solving coping, positive reappraisal, social support seeking, and avoidance coping with the treatment group obtaining higher scores than the control group in all cases. The effects declined after 3 months, but some differences were found in the treatment group obtaining higher scores in problem-solving coping and positive reappraisal and lower in overt emotional expression. The study suggests that reminiscence therapy contributes to mental health by enhancing coping strategies that can allow the elderly to cope successfully and overcome psychological distress.

Measuring elderly people's quality of life through the Beck Hopelessness Scale: a study with a Spanish sample.

OBJECTIVES: Hopelessness is a key element of suicidal intent. It can instill a pessimistic outlook on the future, leading an individual to believe that suicide is the only answer to their problems. Hopelessness operates as a modulating variable between depression and suicidal behavior. The aim of this study was to confirm the factor structure of the Beck Hopelessness Scale (BHS) in a non-clinical sample. METHOD: Three hundred and sixty-two Spanish individuals, aged over 60, free of cognitive impairment and depressive symptoms, completed the BHS scale. Participants were tested using confirmatory factor analysis (CFA), using one-, two- and three-factor models. RESULTS: The one- and two-factor models presented adequate fit indices. Specifically, the indices of the two-factor models were better than those of the one-factor model. The two-factor model, without items 4, 9 and 14, provided the best fit, given that the indices obtained in the CFA and their internal consistency were better than those of the other models. CONCLUSION: The validation of the BHS for a population of Spanish older adults provides a reliable and valid measure of hopelessness and could be useful in clinical practice and research as an effective tool for the early detection of suicidal behaviors.

Can there be learning potential in Parkinson's disease? A comparison with healthy older adults.

Patients with Parkinson's disease may show certain cognitive impairments, although it is unclear how these deficits can affect their learning potential. The study aims to use the testing-the-limits technique to compare the potential for cognitive plasticity in a group of Patients with Parkinson's disease (N = 33) and a group of healthy older adults (N = 33). Sixty-six participants performed verbal learning test to analyze the learning potential. Repeated-measures analysis of variance showed significant main effects of time, group, and the interaction. There is a lower learning potential in subjects with Parkinson's disease; however, those still maintain a certain capacity for learning and, therefore, for cognitive plasticity.

Emotional intelligence in older adults: psychometric properties of the TMMS-24 and relationship with psychological well-being and life satisfaction.

BACKGROUND: Aging is a process during which important changes occur in different areas of development and emotional intelligence plays an essential role. The objective of this study was twofold: first, to validate the TMMS-24 in an older population; and second, to examine the mediating role of life satisfaction in the relationship between emotional intelligence and psychological well-being. METHODS: The sample consisted of 215 older adults (60.15% women) with a mean age of 69.56 (SD = 6.42), without cognitive impairment. Data on emotional intelligence, satisfaction with life, and psychological well-being were obtained through the TMMS-24, the SWLS, and Ryff's psychological well-being scales, respectively. Confirmatory factor analyses and structural equation modeling were conducted. RESULTS: Confirmatory factor analyses confirmed the three-dimensional structure of the TMMS-24. The total scale showed an internal consistency of 0.90, ranging from 0.84 to 0.85 for the subscales. Structural equation modeling indicated that emotional intelligence exerted an influence on psychological well-being both directly and indirectly through life satisfaction. CONCLUSIONS: These findings show that the TMMS-24 has adequate psychometric properties for assessing emotional intelligence in elderly participants, and they indicate that emotional intelligence influences cognitive and affective judgments of life satisfaction, with these judgments of life satisfaction predicting psychological well-being.

Reminiscence functions scale: factorial structure and its relation with mental health in a sample of Spanish older adults.

BACKGROUND: The reminiscence functions scale (RFS) is a 43-item self-report instrument designed to assess the use of reminiscence for different functions. This study aims, on one hand, to analyze the factorial structure and the psychometric properties of the RFS and, on the other, to examine the relationship between the functions of reminiscence and mental health. METHODS: RFS scale and measures of depressive symptomology, despair, and life satisfaction were administered to a sample of persons over the age of sixty (n = 364). RESULTS: After eliminating three conflictive items from the original scale, the confirmatory factor analysis results present a factorial structure comprising eight traditional factors and adequate reliability scores (from 0.73 to 0.87). Using structural equation modeling, we find that these reminiscence factors are organized in three second-order factors (self-positive, self-negative, and prosocial). Results show that the self-positive factor relates negatively and the self-negative factor relates positively with symptoms of mental health problems. CONCLUSIONS: These results, on one hand, confirm that the RFS scale is a useful instrument to assess reminiscence functions in a sample of Spanish older adults and, on the other, that the three-factor model of reminiscence is a better predictor of mental health than the alternative four-factor model.

Anxiety-related reactions associated with magnetic resonance imaging examinations.

OBJECTIVE: To review the epidemiology of anxiety-related reactions during magnetic resonance imaging (MRI) examinations, the feasibility of identifying patients at risk, and the management strategies that have been applied. DATA SOURCES: Published original articles were retrieved using computerized MEDLINE searches encompassing 1980 through April 1993. Further references were obtained from the primary sources. STUDY SELECTION AND DATA EXTRACTION: All studies obtained through the data search were chosen for review. All data relevant to anxiety-related reactions were analyzed. DATA SYNTHESIS: Anxiety-related reactions occur in approximately 4% to 30% of patients undergoing MRI, ranging from apprehension to severe reactions that interfere with the performance of the test. Criteria for diagnosis or categorization of the reactions and identification of patients at risk are scanty. Several management strategies have been proposed, including patient education, drug therapy, and cognitive-behavioral intervention. CONCLUSIONS: While a more precise characterization of the nature and incidence of anxiety-related reactions during MRI examinations and better methods of recognizing patients at risk are desirable, a strategy for general and individual prophylaxis, identification of patients at risk, and individual patient management can be developed on the basis of current knowledge.
