The link between memory performance, self-assessment, and affective status

Subjective memory measures: Metamemory questionnaires currently in use

Subjective memory evaluation is important for assessing memory abilities and complaints alongside objective measures. In research and clinical settings, questionnaires are used to examine perceived memory ability, memory complaints, and memory beliefs/knowledge. Although they provide a structured measure of self-reported memory, there is some debate as to whether subjective evaluation accurately reflects memory abilities. Specifically, the disconnect between subjective and objective memory measures remains a long-standing issue within the field. Thus, it is essential to evaluate the benefits and limitations of questionnaires that are currently in use. This review encompasses three categories of metamemory questionnaires: self-efficacy, complaints, and multidimensional questionnaires. Factors influencing self-evaluation of memory including knowledge and beliefs about memory, ability to evaluate memory, recent metamemory experiences, and affect are examined. The relationship between subjective and objective memory measures is explored, and considerations for future development and use of metamemory questionnaires are provided.

Positive psychological constructs and cognitive function: A systematic review and meta-analysis

AIM

To synthesise evidence regarding the association between positive psychological constructs (PPCs) and cognitive function in adults aged 50 +.

METHODS

Literature searches: Medline, PsycINFO, and Scopus (inception to February 2022). Studies were included if they reported on the association between at least one PPC and one objective measure of cognitive function in people aged 50 + without cognitive impairment at baseline. Where at least two studies reported on the same PPC and cognitive outcome, estimates were pooled through meta-analysis.

FINDINGS

In total, 37 studies were included. There was evidence of cross-sectional associations for 'meaning in life' (verbal fluency: b = 0.09, 95 %CI [0.07, 0.11], p < .001; memory: b = 0.10, 95 %CI [0.08, 0.12], p < .001), 'purpose in life' (verbal fluency: b = 0.07, 95 %CI [0.05, 0.08], p < .001; memory: r = 0.13, 95 %CI [0.08, 0.18], p < .001), and positive affect (cognitive state: r = 0.25, 95 %CI [0.14, 0.36], p < .001; memory: r = 0.05, 95 %CI [0.02, 0.08], p < .001) with various domains of cognitive function. However, no significant results were found for life satisfaction (p = .13) or longitudinal studies investigating positive affect and memory (p = .48). Other PPCs were included in narrative syntheses only.

IMPLICATIONS

Purpose and meaning in life may be sensible primary targets for interventions to promote healthy cognitive aging. More longitudinal and causal inference research is needed to better understand this association and its implications for clinical practice.

Depressive Symptoms as a Predictor of Memory Complaints in the PRISM Sample

Objectives

The current study investigated baseline and longitudinal relationships between memory complaints, depressive symptoms, and cognition in older adults.

Method

Using the sample from the Personal Reminder Information and Social Management trial, we generated path models predicting self-rated memory complaints measured by the Memory Functioning Questionnaire (MFQ).

Results

Our baseline models showed that more depressive symptoms were associated with reporting more frequent forgetting incidents and a greater decline in memory function. The baseline models also revealed that higher scores in a latent cognitive function were associated with reporting a greater decline in memory functioning and a greater use of mnemonics. However, cognitive predictors did not mediate the baseline associations between the MFQ measures and depressive symptoms. Further, these predictors were not able to directly predict the 12-month MFQ measures over and above the baseline effects. Including personality traits (neuroticism and conscientiousness) did not significantly affect the models.

Discussion

Our results suggest that memory complaints about frequency of forgetting can be the most reliable indicator of depression risk among the four factors in the MFQ. We discuss theoretical implications for longitudinal relationships between memory complaints, depressive symptoms, and cognitive function in older adults.

Prevalence and correlates of subjective memory complaints in Vietnamese adults

ABSTRACTBackground:Low- and middle-income countries such as Vietnam are home to a majority of the world's population with dementia, yet little is known regarding how individuals in these countries perceive memory problems that might be indicative of cognitive impairment. This study examined the prevalence and correlates of subjective memory complaints (SMCs) in Vietnamese adults in Da Nang, Vietnam.

METHODS

A stratified sample of 600 adults (aged ≥ 55 years) living in Da Nang, Vietnam, and surrounding areas were recruited to participate in a cross-sectional study. Students and faculty from the National Technical Medical College Number 2 administered questionnaires in participants' homes regarding socio-demographic characteristics, functional health, social support, cognitive and mental health, and SMCs. Descriptive and stepwise regression analyses examined the prevalence and correlates of SMCs.

RESULTS

Approximately 64% of the sample reported at least poor memory and 39% said that memory interfered with their daily life at least somewhat. Multivariate regression analyses (adjusted for all covariates) showed that depressive symptoms, cognitive impairment, self-rated health and pain, and material hardship were associated with SMCs.

CONCLUSIONS

Prevalence of SMCs as well as depressive symptoms was high in this Vietnamese population. Although future research using more detailed measures of subjective memory and which include longitudinal data are required, the need for physicians to routinely assess Vietnamese patients for depression, SMCs, and cognitive impairment may be warranted.

Age does not matter: Memory complaints are related to negative affect throughout adulthood

OBJECTIVES

Memory complaints are present in adults of all ages but are only weakly related to objective memory deficits, raising the question of what their presence may indicate. In older adults, memory complaints are moderately related to negative affect, but there is little research examining this relationship in young and middle-aged adults. This study examined whether memory complaints and negative affect were similarly related across the adult lifespan and in adults with varying levels of objective memory performance.

METHOD

The sample included 3798 healthy adults, aged 18 to 99, and was divided into five groups: young, middle-aged, young-old, old-old, and oldest-old adults. Participants completed questionnaire measures of memory complaints and negative affect (neuroticism and depressive and anxiety symptoms), in addition to lab measures of objective memory.

RESULTS

Using structural equation models, we found that the relationship between memory complaints and negative affect was moderate in all the age groups, and there was no evidence for moderation by objective memory.

CONCLUSION

For adults of all ages, perceived memory decline may be distressing and/or negative affect may lead to negative self-evaluations of memory.

Administering the Digit Span Subtest of the WISC-III to Children With Attentional, Emotional, and Learning Difficulties: Should the Examiner Make Eye Contact or Not?

This study examined the impact of eye contact versus no eye contact during the administration of the Digit Span subtest of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) to a clinical population of children. Forty-three children, ranging in age from 6 to 16 years, participated in the study, representing a range of attentional, emotional, and learning diagnoses. Participants were administered the Digit Span subtest once with and once without the examiner offering eye contact, in counterbalanced order. Results indicated that respondents generally avoided making eye contact with the examiner, even during the eye contact condition, suggesting that eye contact is at least not preferred during recall of Digit Span numbers. Performance was not impacted by the eye contact behavior of the examiner as respondents generally avoided eye contact. Implications for examiner eye contact behavior during administration of the Digit Span to a clinical population of children are discussed.

Metamemory in Temporal Lobe Epilepsy

The impact of depression on self-perception of memory has been well documented in a variety of populations. We examined the relationship between metamemory (defined as awareness of memory capacities and deficits), actual memory performance, depression, and laterality of epileptogenic focus in surgical candidates with medically refractory temporal lobe epilepsy (TLE) (N = 151) and with healthy controls (N = 63). Compared to healthy controls, presurgical TLE patients reported more difficulties in memory on self-rating and activities of daily living rating scales, performed worse on tests of memory, and were less accurate in self-perception of memory capacity when compared to actual test performance. Patients reported more depression than controls, but there were no differences in level of depression or accuracy of metamemory between right and left TLE patients. Presurgical TLE patients who were depressed reported more memory impairment and underestimated their memory, but did not differ in actual memory performance. Results suggest that depression plays an important role in self-perceived memory impairment in patients with refractory TLE.

Assessing Self-Rated Memory Impairment in Persons with Posttraumatic Headache

Forty-two patients with persistent posttraumatic headache and postconcussion symptomatology following a motor vehicle accident completed the Self-Rating Scale of Memory Functions (SRSM), the Beck Depression Inventory (BDI), and brief memory testing. SRSM scores indicated that patients rated their memory as significantly impaired relative to their preinjury status. SRSM scores were not affected by such factors as age, education, gender, and loss of consciousness. However, significantly depressed patients rated their memory as more impaired on 14 of 18 SRSM items when compared with nondepressed patients. After controlling for depression, SRSM scores correlated significantly with objective performance on several memory tests. The implications of these findings are discussed.

Predictors of Memory in Young-old and Old-old Adults

A contextualist approach was adopted to assess cognitive functioning and psychological well-being in a representative sample of young-old (60-74 years, n = 107) and old-old (75-92 years, n = 58) women and men in an effort to: (1) delineate age and gender similarities and differences within this elderly cohort; and (2) identify individual differences predictive of remembering. Measures of subjective well-being included morale, depression, and perceived control. Cognitive measures included intentional story recall and incidental symbol memory, rate of information processing, and cognitive flexibility. Health status, gender, and education were also investigated. Decrements were observed in intentional and incidental memory, rate of information processing, solution of Raven's Coloured Progressive Matrices, and Mini-Mental Status Examination, but not on accuracy of information processing, estimates of intelligence, well-being measures, education, or health status. The intentional story memory of women was more accurate than that of men. Education and gender, along with processing speed and mental ability, as indexed by the Raven coloured matrices, predicted story memory. These results of a representative sample validate recurrent trends seen in previous convenience samples. They extend the understanding of the relationship between ageing and cognition by identifying the role of processing resource, psychosocial, and demographic factors in modulating memory performance and highlighting methodological factors which must temper interpretation of these relationships.

Preliminary support for a generalized arousal model of political conservatism

It is widely held that negative emotions such as threat, anxiety, and disgust represent the core psychological factors that enhance conservative political beliefs. We put forward an alternative hypothesis: that conservatism is fundamentally motivated by arousal, and that, in this context, the effect of negative emotion is due to engaging intensely arousing states. Here we show that study participants agreed more with right but not left-wing political speeches after being exposed to positive as well as negative emotion-inducing film-clips. No such effect emerged for neutral-content videos. A follow-up study replicated and extended this effect. These results are consistent with the idea that emotional arousal, in general, and not negative valence, specifically, may underlie political conservatism.

Étude des relations entre des measures d'évaluation subjective et objective de mémoire et des mesures psychosociales chez des personnes âgées entre 55 et 65 ans

A review of the literature shows that only a weak connection exists between objective memory tests and self-evaluation memory questionnaires. The object of the present study was to explore which of the mnemonic, affective or psychosocial factors influence subjective evaluation of the memory function. This study is composed of a self-evaluation memory questionnaire, an ecologic-type objective memory evaluation, two affective state measures, anxiety and depression, and an inventory of life events. Sixty elderly persons took part in the study. They were divided into two groups, with attribution to a group depending on whether or not they considered themselves to have problems with memory Results supported the hypothesis that subjective and objective evaluations of memory comprise different components. Contrary to an objective test, self-evaluation of memory is strongly related to affect rather than being a perfect representation of actual mnemonic ability and this in spite of the ecological character of the memory test.

Determining long-term symptoms following mild traumatic brain injury: Method of interview affects self-report

PRIMARY OBJECTIVE

To examine the role played by two interviewing methods used (spontaneous response and suggested response) in the evaluation of long-term subjective post-mild traumatic brain injury (mTBI) symptoms.

RESEARCH DESIGN

Cohort study.

METHOD AND PROCEDURES

One hundred and eight adult participants were contacted for a follow-up telephone interview 12-36 months after their mTBI. The participants had to firstly spontaneously indicate symptoms that were still present following their mTBI (spontaneous response). Secondly, a list of symptoms was read to the participants and they had to say whether or not they were afflicted by each symptom (suggested response). Paired t-tests were performed to compare the means obtained using the two methods. The percentage of symptoms reported with the two interviewing methods were used to analyse symptom types.

EXPERIMENTAL INTERVENTION

None.

MAIN OUTCOMES AND RESULTS

Results show that participants reported significantly more symptoms and a given symptom when a list was read to the participants. Furthermore, neither the number of symptoms nor the type of symptoms reported is identical for the two interviewing methods.

CONCLUSION

The interviewing method used influences the number and type of long-term post-mTBI symptoms reported by participants.

Subjective evaluation of the therapeutic and cognitive effects of electroconvulsive therapy

BACKGROUND

Methods used to evaluate subjective effects of electroconvulsive therapy (ECT) have relied on self-report about discrete aspects of memory. Although objective deficits are demonstrable, patients generally report improved memory after ECT. Patients have not been asked to evaluate the global impact of ECT on mood or memory. This study was undertaken to compare patients' evaluations of ECT outcomes using direct questioning about global impact compared with standard methods.

METHODS

A prospective, naturalistic study was conducted in seven hospitals. Patients completed clinical and neurocognitive assessments before ECT, including the Cognitive Failures Questionnaire (CFQ), the Autobiographical Memory Interview-Short Form, and a novel interview assessing expectations about the impact of ECT on mood and memory (Global Self-Evaluation-Mood [GSE-Md], GSE-memory [GSE-My]). Follow-ups were conducted one and 24 weeks after ECT, and the GSE-Md and GSE-My evaluated perceived global impact at these time points.

RESULTS

Patients reported marked improvement after ECT on the CFQ, a traditional instrument assessing specific cognitive complaints. CFQ and depression severity scores were strongly correlated. On the GSE-My, patients reported a deleterious memory effect both one and 24 weeks after ECT. GSE-My, but not CFQ, scores were associated with treatment technique and long-term retrograde amnesia.

CONCLUSIONS

Characterization of patients' experience of cognitive side effects after ECT differs markedly depending on assessment method. Direct questioning about global impact revealed more negative views and associations with objective indices of cognitive impairment. This represents the first report of concordance between subjective and objective measures of the effects of ECT on memory.

Self-report of cognitive abilities in temporal lobe epilepsy: cognitive, psychosocial, and emotional factors

Self-report of cognitive functioning using the Multiple Abilities Self-Report Questionnaire (MASQ) was examined in 57 left (LTLE) and 36 right (RTLE) temporal lobe epilepsy patients. The MASQ is a 38-item self-report measure assessing five domains of self-perceived cognitive functioning: Language, Visual-Perceptual Abilities, Verbal Memory, Visual-Spatial Memory, and Attention/Concentration. Overall, LTLE patients self-reported more cognitive difficulties across all domains. Language was the only domain to emerge as a robust indicator of seizure lateralization (LTLE patients reporting more problems). Neuropsychological test performance did not emerge as a significant predictor for any domain, whereas measures of psychosocial and emotional functioning accounted for a significant but modest amount of variance in all of them. The results suggest caution in using such self-report measures as an ecological extension of objective testing, but suggest a role in assessing self-appraisal of deficits.

A 10-item Rasch modeled memory self-efficacy scale

A 10-item scale to measure memory self-efficacy was developed from responses to the 33-item Frequency of Forgetting scale of the Memory Functioning Questionnaire (MFQ). Responses to the MFQ from 565 participants in the 1994-1995 wave of the Long Beach Longitudinal Study were analyzed. Rasch scaling procedures were used to select items that discriminated individuals' scoring patterns and that provided non-redundant information about responses. A set of 10 items provided a scale that was reliable across items and persons. Female gender, conscientiousness score, depression score, and list recall predicted individual differences in participants' scores on the scale. Age, education, neuroticism, and text recall were also reliably correlated with scores but were suppressed by the other covariates. The shortened test is predicted by the same covariates as the long version, indicating that it has similar construct validity.

Longitudinal hierarchical linear models of the memory functioning questionnaire

Three hypotheses about the nature of self-rated memory as measured by the Memory Functioning Questionnaire (MFQ; M. J. Gilewski, E. M. Zelinski, & K. W. Schaie, 1990) were tested: that ratings reflect memory performance, that personality traits underlie ratings, and that ratings reflect implicit theories of memory change. Baseline scores and 19 year change slopes for the 4 MFQ factor ratings of a sample of 97 participants aged 30-81 were investigated. There were significant mean declines for all MFQ ratings except Frequency of Forgetting and significant individual differences in slopes for Frequency, Retrospective Functioning, and Mnemonics. Personality predicted baseline Frequency and Seriousness ratings and list and text recall slopes predicted Mnemonics slopes. Different mechanisms may underlie baseline ratings and changes in ratings for different factors.

Assessing absentmindedness: prospective memory complaint and impairment in middle-aged adults

In two experiments, metamemorial differences between prospective and retrospective memory performance were examined. Participants in Experiment 1 were recruited through newspaper advertisements and comprised middle-aged women who experienced exceptional problems in prospective remembering. Experiment 2 involved self-reporters and nonreporters of retrospective memory problems, who were selected from a large population-based sample of middle-aged adults. In both experiments, memory performance was assessed by using a variety of tasks, including five retrospective memory tasks and three prospective memory tasks that varied in level of realism and retrieval support. In both experiments, there were selective differences in memory performance, so that participants who experienced (retrospective or prospective) memory problems showed impaired performance in prospective, but not in retrospective, memory tasks. These findings suggest that memory for future intentions provides a more sensitive task criterion than does memory for past events for assessing individual differences in self-reports of episodic memory problems. Task-specific differences in reliance on frontally mediated executive processes might underlie these differences.

Relations between subjective evaluations of memory and objective memory performance

Several explanations for the weak relations between subjective memory judgements and objective memory performance were investigated in two groups of normal older adults. Group 1 sampled a general population (mean age 61.6 yr., range 46-89), while Group 2 sampled subjects who were on a waiting list for memory training (mean age 63.0 yr., range 45-85 years). In both groups, subjective memory judgments were assessed with global ratings of memory capacity and with ratings of frequency of forgetting in specific memory situations. Memory performance was assessed with several well-known tests and with recently developed tests for domain-specific aspects of memory. Most tests concerned episodic memory. Study 1 also included measures of semantic, incidental and working memory. Study 2 further examined the influence of the domain-specificity of objective and subjective measures for remembering names, intentions, and texts. Relations between memory self-reports and performance were weak in both groups and for all kinds of tests. Against expectations, the low correlations could not be explained by differences between ecological and laboratory tests or incidentally and intentionally remembered information, or by differences between specific failures compared to global, stereotyped judgments. Surprisingly, correlations did not increase when subjective and objective measures assessed the same ability, like remembering names. Also noncognitive variables (mood and lifestyle) did not influence the relations. The (weak) relations between subjective and objective memory measures were comparable for subjects over and under 65 years of age. Furthermore, relations were comparable for the general population sample and the memory compliant group.

The relationship between subjective and objective memory in the oldest old: comparisons of findings from a representative and a convenience sample

OBJECTIVES

To evaluate the hypotheses that subjective memory ratings are more accurate in the oldest old than in the young old and more accurate in a representative sample than in a convenience sample.

METHODS

Outcomes of hierarchical regressions of subjective ratings and participant characteristics on recall were compared between a nationally representative sample of 6,446 adults ages 70 to 103 and a convenience sample of 326 adults ages 70 to 97.

RESULTS

Education interacted with memory ratings in the prediction of performance in the representative sample, with better prediction for more highly educated participants than for participants with lower levels of education.

DISCUSSION

The general pattern of findings was consistent across both samples and neither hypothesis was supported. Possible explanations for the similarity of results across samples are considered.

Quality of life self-assessment as a function of lateralization of lesion in candidates for epilepsy surgery

PURPOSE

This prospective study aimed to investigate the relationship(s) of the laterality of the epileptogenic lesion to personality factors, emotional processing, and the subjective experience of quality-of-life (QOL) self-assessment in candidates for epilepsy surgery.

METHODS

Patients who were candidates for epilepsy surgery were studied. Eighteen of them (aged 19-61 years) had localization-related epilepsy in the right temporal lobe (RTLE), 18 (aged 21-50 years) had localization-related epilepsy in the left temporal lobe (LTLE), and 20 were demographically matched normal subjects. The Spielberger Trait/State Anxiety questionnaire and the QOLIE-31 questionnaire for self-assessment of quality of life were used. One-way analysis of variance, Pearson correlations, and linear regression analyses were performed on group and anxiety levels and QOLIE variables.

RESULTS

LTLE patients systematically showed higher levels of anxiety and lower self-estimates of the quality of their lives when compared with RTLE patients. All anxiety measures were highly correlated with Total QOL in LTLE (p < 0.05) but not in RTLE patients; however, different parameters of QOL showed different relationships with measures of anxiety. Results of multiple regression analyses suggested that the level of anxiety was relatively stable and less affected by QOL factors in LTLE as compared with RTLE patients (p = 0.03).

CONCLUSIONS

A high level of anxiety shown by LTLE patients may represent a personality trait and cause a response bias in overreporting of negative symptoms and a decreased self-assessment of QOL. It may also present a presurgical risk factor, particularly for patients with LTLE lesions. Appropriate patient counseling is advised.

Memory complaint in a community sample aged 70 and older

OBJECTIVES

The ability of older people to estimate their own memory, often referred to as "metamemory," has been evaluated in previous studies with conflicting reports regarding accuracy. Some studies have suggested that an older person's metamemory is mostly accurate, whereas others have demonstrated little relationship between memory complaint and actual impairment. This study examines memory complaint in a large national sample of older people aged > or = 70.

DESIGN

A longitudinal cohort study with two waves of data collection spaced 2 years apart.

SETTING

A nationwide random sample of community-dwelling older persons.

PARTICIPANTS

A total of 5,444 community-dwelling persons aged > or = 70 and their spouses.

MEASUREMENTS

Participants were asked if they believed their memory was excellent, very good, good, fair, or poor. They were then administered a cognitive assessment derived from the Mini-Mental Status Exam.

RESULTS

In general, people's assessment of their memory corresponded with their actual performance on cognitive measures. However, large portions of the sample inaccurately assessed their memory skills. People who reported depressive symptoms and had impairment in activities of daily living were more likely to state that their memory was impaired, although they performed very well on cognitive measures.

CONCLUSIONS

The conditions that skew people's self-assessment are the ones most likely to bring them into contact with healthcare professionals. This may give clinicians the general impression that older people cannot assess their own cognitive skills. However, poor metamemory appears to be a characteristic of a specific subgroup of older persons, not necessarily characteristic of the general population.

Neuropsychological evaluation of everyday memory

The evaluation of everyday memory (EM) was reviewed and reconceptualized. EM has established new objectives of study and the development of new methods to reach these objectives. At the basic level, this approach has already produced important discoveries and the development of new principles about memory and functioning. At the clinical level, this new area of investigation has resulted in evaluating deficits of EM, which is defined as what daily life functions remain impaired after a deficit pathology has occurred. A type of evaluation has evolved that is oriented toward treatment and extremely useful in designing rehabilitation programs for individuals with alterations in memory.

A study of the efficacy of a comprehensive memory enhancement program in healthy elderly persons

Well educated, high functioning older adults (ages 60-90) were given a comprehensive memory enhancement training program to determine the effectiveness of the program in increasing cognitive performance and positively influencing self-assessments of memory efficacy. The 68 subjects who participated in the memory enhancement training were compared to 74 subjects who were enrolled in a video control group. Between subject differences were analyzed prior to the interventions and at three time points following the interventions (immediately post, 3 months and 6 months). Only one cognitive measure, assessing verbal memory, revealed a significant difference between the groups, with participants in the memory enhancement group showing less decline from baseline than the video control group immediately following the intervention but with no difference between groups at 6 months post-intervention. Several self-report measures showed that the memory enhancement training subjects experienced improved memory functioning and decreased memory concerns relative to the video control group. The self-reported effects of the training were sustained over the 6-month follow-up period.

Research on cognitive complaints and cognitive functioning in patients with chronic fatigue syndrome (CFS): What conclusions can we draw?

People with chronic fatigue syndrome (CFS) complain of difficulties with concentration and memory yet studies suggest that they do not suffer gross deficits in cognitive functioning. Depressed patients make similar cognitive complaints, and there is symptomatic overlap between CFS and depression. Cognitive complaints and depressed mood are positively correlated in CFS patients but, except on tasks which are particularly sensitive to depression, cognitive performance and depression are not. The inconsistency between cognitive complaints and results of tests of cognitive functioning resembles that found in other subject groups and may be due in part to the inappropriate use of laboratory memory tests for assessing "everyday" cognitive functioning. Even when cognitive capacity is intact, cognitive performance may be affected by factors such as arousal, mood, and strategy. In CFS patients, everyday cognitive tasks may require excessive processing resources leaving patients with diminished spare attentional capacity or flexibility.

Increasing metamemory in older adults

The purposes of this study were to test the effects of a 2-week, four-session group intervention with older adults, designed to increase memory self-efficacy and memory performance and to evaluate the influence of depression on memory self-efficacy. A total of 145 community-dwelling older adults (M = 71 years) participated in the study. The intervention significantly increased both memory self-efficacy and memory performance in the treatment group (n = 74). In addition, the treatment group's perception of control in memory-demanding situations was strengthened, and their perception of negative changes in memory over time was diminished. The control group (n = 71) experienced a significant decline in memory self-efficacy over time. Memory performance was not significantly related to memory self-efficacy. Those individuals with depression (M = 7.5), as measured by the short Geriatric Depression Scale, had significantly lower memory self-efficacy scores than those without depression; however, there was no difference in memory performance between the depressed and nondepressed subjects. From the posttest to the follow-up period, depressed subjects receiving the intervention showed a significant decrease in memory self-efficacy, while nondepressed subjects showed no change.

Effects of hypericum extract on the sleep EEG in older volunteers

The effects of treatment with high doses (300 mg three times daily) of hypericum extract LI 160 on sleep quality and well-being were investigated over a 4-week period. The double-blind, placebo-controlled study was conducted with 12 older, healthy volunteers in a cross-over design, which included a 2-week wash-out phase between both treatment phases. A hypostatic influence of the REM sleep phases, which is typical for tricyclic antidepressants and MAO inhibitors, could not be shown for this phytopharmacon. Instead, LI 160 induced an increase of deep sleep during the total sleeping period. This could be shown consistently in the visual analysis of the sleeping phases 3 and 4, as well as in the automatic analysis of slow-wave EEG activities. The continuity of sleep was not improved by LI 160; this was also the case for the onset of the sleep, the intermittent wake-up phases, and total sleep duration.

Memory complaints before and after temporal lobectomy: do they predict memory performance or lesion laterality?

The relationships among self-report of memory, actual memory performance on objective tasks, and lesion laterality were examined in this longitudinal study. Right-handed adults (n = 47) with medically intractable seizures were assessed both preoperatively and 1 year after a left or right temporal lobectomy. Memory complaints remained stable or diminished postoperatively, whereas performance on material-specific memory tasks declined. Regression analyses showed that dosage of medications, seizure frequency and self-reported depression were predictive of postoperative memory complaints, although size of resection and age were not. Together, these data suggest that many patients have a positive though mistaken impression that their memory functions improved after temporal lobectomy, an impression influenced by their positive surgical outcomes. Memory complaints did not predict laterality of the lesion. Sex-laterality interactions were evident for both subjective and objective memory measures.

Age-related Deficits in Intentional Memory for Spatial Location in Small-scale Space: A Meta-Analysis and Methodological Critique

Le but de cette méta-analyse était d'estimer l'effet du vieillissement sur la mémoire intentionnelle de locations dans un espace de petite dimension. Les résultats de 22 études, représentant au total 1 598 sujets, ont été comparés grâce aux indices suivante: (a) d (Cohen, 1988), (b) omega2 (Hays, 1963), et (c) Proportion des sujets classifiés. La méta-analyse suggére que l'effet du vieillissement est «large» (e.g., d moyen de 0.81), et que cet effet est proportionnel au nombre de dimensions de l'espace utilisé. Toutefois, la validité de ces conclusions est incertaine lorsqu'on considére les limites méthodologiques des études recensées. En particulier, moins de la moitié de ces études ont mentionné avoir contrôlé l'effet possible de variables telles que (a) l'acuité visuelle, et (b) la durée de la phase de rappel. Il est proposé que compte de ces variables exogénes.

Developing a model of quality of life in epilepsy: the contribution of neuropsychology

Three specific issues must be considered in the development of a quality-of-life in epilepsy model and psychometric instrument. These issues are: (a) whether to adopt a narrow versus broad model of quality of life, (b) whether to rely on patient self-reports of quality of life or reports garnered from proxies, and (c) whether to develop a generic versus disease-specific measure of quality of life. In reviewing these issues the contributions of the health services research field, research pertaining to the psychological and social effects of epilepsy, and especially neuropsychology, are pertinent.

The association of memory complaint with computer-simulated everyday memory performance

The relationship of memory self-report to self-rated depression and to actual performance on computer-simulated everyday memory tasks was investigated in 125 normal adults. Canonical correlation analyses demonstrated that self-rated memory performance and objective computer-simulated everyday memory performance shared from 27.9% to 29.4% of common variance. These data provide initial concurrent validity for a new memory self-report scale, the MAC-S. Results are discussed in relation to psychometric factors important in the design and validation of self-report memory scales.

Self-rating and objective memory testing of normal and depressed elderly

This study aimed to assess the relationships between the scores of subjective assessment (metamemory) and those of performance testing for memory, on the one hand, and the level of depression, on the other. A hundred and eighty elderly subjects (102 women and 78 men; mean age 65.7 years) were selected for the study. They showed neither intellectual impairment (as assessed through Mini Mental State test: MMS) nor neuropsychiatric symptoms. Each subject was administered the Randt Memory Test (RMT) for performance testing, the Sehulster Memory Scale (SMS) for the subjective assessment, and the Geriatric Depression Scale (GDS). A MULTCOVA analysis showed that both age and the depression level are negatively correlated with both the measures (Acquisition-Recall: AR; Delayed Memory: DM) of the RMT. The scores of the second (memory complaints) of the three sets of SMS were positively correlated with those of AR and DM indices. A Multivariate Regression Analysis showed that in males age and the depression level were significant regressors for both AR and MD scores while in females only the depression level was a significant regressor for AR and only age was a significant regressor for DM. Our results suggest that a) the relationships between the depression level and memory functioning are close, although not fully homogeneous in men and women; and b) that the scores in some areas of metamemory parallel, independently of the level of depression, the performance outcomes of memory functioning.

Measurement of affective states in adults. Evaluation of an adjective rating scale instrument

A cross-sectional sample of adults, ages 20-79, were administered an adjective rating scale instrument measuring multiple affective states, including items from the Profile of Mood States (POMS) instrument. Confirmatory item factor analysis supported, for the most part, a priori assignments of items to scales based upon prior research, but revealed a few small, additional item factors that were cross-validated in a second sample. Items measuring different aspects of psychological distress, including anxiety and depressive affect, showed appreciable skew and kurtosis, with a substantial proportion of respondents indicating no perceived distress. Items measuring psychological well-being tended to show more normal response distributions. Tests of age-related invariance in item factor structure indicated that the unstandardized factor pattern weights (loadings) were not fully equivalent across two age groups, but showed that the same configuration of items loading on factors was supported. The scales perform well enough to justify continued use in older populations, but further research on the contributions of item distributions to age differences in factor loadings is needed.

On the differentiation of memory beliefs from memory knowledge: the factor structure of the Metamemory in Adulthood Scale

This study was designed to test the hypothesis that there are multiple factors of metamemory present in the Metamemory in Adulthood (MIA) questionnaire. Data on seven MIA scales from six separate studies on memory/metamemory relationships (total N = 750) were combined to yield two half-samples for cross-validation purposes. The samples were partitioned into young, middle-aged, and old groups. A multiple group confirmatory factor analysis was then conducted on the data, using the first half sample to develop a model and the second half sample to validate it. Although the models did not fully cross-validate, both analyses indicated that there are at least two higher-order factors in the MIA. The first involves beliefs about self-efficacy in using memory. The second factor combines knowledge about memory and affect concerning memory (e.g., achievement motivation). The analyses also indicated that the factor loadings for the second factor, tentatively labelled Knowledge, were invariant across the three age groups, but that there were age differences in the Self-Efficacy Beliefs factor loadings. The differences were localized to age-related increases in the loadings for the MIA Change and Locus scales. The two factor solution has potential for resolving conflicting results in the literature regarding age differences in both metamemory and metamemory/memory performance relationships.
