Memory complaints in chronic stroke patients are predicted by memory self-efficacy rather than memory capacity (Article)

Background: Memory self-efficacy (MSE) is the belief about one's mastery of memory functioning. In healthy elderly, memory complaints are related to MSE rather than to objectively measured memory capacity. MSE has scarcely been studied in patients that suffered a stroke. The aim of this study was twofold: (1) to examine whether memory capacity and MSE can predict the presence of memory complaints in stroke patients, and (2) to study which variables are the best predictors of MSE. Methods: In a cross-sectional study, 136 stroke patients (>18 months after onset) were recruited from April 2008 to November 2009. MSE was measured using the Metamemory in Adulthood questionnaire. Depression, coping and personality were measured using validated questionnaires, and memory performance was measured using the Rivermead Behavioural Memory Test (RBMT) and the Auditory Verbal Learning Test (AVLT). Patients were divided into a 'complaints' and a 'no complaints' group. Results: A lower MSE score was an independent predictor of having memory complaints (adjusted odds ratio: 0.422; p = 0.000), adjusted for age and depression. The RBMT and AVLT scores did not predict the presence of memory complaints (p > 0.263). Presence of memory complaints and depression were the strongest predictors of MSE (B = -1.748, p = 0.000; B = -0.054, p = 0.000), followed by word fluency, not having a partner and side of stroke (B = 0.038, p = 0.012; B = -0.517, p = 0.082; B = -0.479, p = 0.088). Conclusions: Memory complaints are predicted by MSE rather than memory capacity. MSE memory training might be an effective training strategy for reducing memory complaints in selected chronic stroke patients. Copyright

Memory self-efficacy and psychosocial factors in stroke (Article)

2008-09-01T00:00:00Z

Objective: To explore whether Memory Self-efficacy is related to depression, neuroticism and coping in patients after stroke, as it is in healthy elderly subjects. Design: A cross-sectional design. The relation between Memory Self-efficacy and psychosocial factors was analysed using a Mann-Whitney U test and non-parametric Spearman correlations. Patients: Seventeen male and 6 female patients after stroke from an inpatient rehabilitation setting were included. Methods: Memory Self-efficacy, depression, neuroticism and coping were assessed with validated questionnaires. Patients with severe aphasia, subarachnoidal haemorrhage or subdural haematomas were excluded. Results: As in healthy elderly subjects, higher depression ratings are significantly related to lower Memory Self-efficacy ratings (Z=-2.13; p=0.033). Lower Memory Self-efficacy seems related to higher neuroticism ratings and a more passive coping style score (Z=-1.54; p=0.123; Z=-1.42; p=0.155, respectively). The Spearman correlations confirm these finding (p<0.10). Conclusion: This study replicated the relationships between Memory Self-efficacy and depression and neuroticism found in a healthy population, in an inpatient stroke population. Future research on Memory Self-efficacy in patients after stroke should focus on other potential determinants such as awareness and, ultimately, on the effectiveness and efficacy of interventions aimed at Memory Self-efficacy to improve participation and quality of life. © 2008 The Authors.

Mental work demands protect against cognitive impairment: MAAS prospective cohort study (Article)

2003-01-01T00:00:00Z

Little is known about whether persons with mentally demanding jobs are protected against cognitive impairment and whether this association is independent of intellectual abilities and other confounders. Longitudinal data from the Maastricht Aging Study (MAAS) were used to examine this association. After the 1993-1995 baseline examination, there was a first 3-year follow-up examination (1996-1998) among 630 men and women, aged 50 to 80, who exhibited no cognitive impairment at baseline. Persons with mentally demanding jobs had lower risks of developing cognitive impairment during follow-up (36 cases), compared with persons without such jobs (odds ratio = 0.79; 95% confidence interval: 0.65-0.96). About 1.5% of the persons with high mental work demands developed impairment compared to 4% of the persons with few work demands. The protective effect was independent of intellectual abilities and other confounders. Our findings provide evidence that continued and potentially modifiable mental stimulation during adult life may protect men and women against cognitive impairment.
