Interactive effects of subjective memory complaints and hypertension on learning and memory performance in the elderly

This study evaluated whether the relation between subjective memory complaints and cognitive performance is influenced by the presence of hypertension in the elderly. One hundred and five healthy older adults, 70–89 years of age, with and without hypertension treatment or diagnosis, completed a scale of subjective memory complaints. Participants were divided into those with mild memory concerns and those with minimal or no complaints. All participants completed a battery of neuropsychological tests including measures of verbal and nonverbal memory. After controlling for differences in age, gender, education, and overall intellectual ability, there were significant main effects for memory concerns and significant interactions for memory complaints and hypertension on several measures of memory performance. There were no main effects for hypertension on memory performance. Simple effects analyses of the interactions showed that the hypertensive complainers demonstrated poorer performance on measures of long-term memory and greater reliance on short-term recall than the hypertensive non-complainers. There were no differences in memory performance for the non-hypertensive groups. Among healthy elderly community-dwelling adults, those with mild subjective memory complaints in the context of hypertension demonstrated greater objective cognitive difficulties than those without hypertension as well as a greater reliance on a less efficient learning strategy. These findings suggest that memory concerns in the presence of hypertension may be important when evaluating treatment efficacy in these individuals and for identifying differences in cognitive aging.     

Subjective cognitive complaint in healthy older adults: Identification of major domains and relation to objective performance

This study analyzed complaints across a range of memory domains in middle-aged and older adults, as well as assessed their relationship with objective cognitive performance and personal characteristics. A total of 115 community-dwelling, healthy adults between the ages of 45 and 87 completed the Self-Evaluation Questionnaire (QAM) and were tested with a comprehensive neuropsychological battery. A principal component analysis identified seven dimensions of complaint. Difficulty inhibiting internal and external sources of interference when learning or remembering something was the main area of complaint and it was correlated with word-list recall and Digit Symbol. We identified complaints related to a set of memory failures that appear to be more detrimental to autonomy and safety. These were correlated with a measure of functional autonomy and might, therefore, indicate more severe difficulties. Overall, this study provides indications regarding the main domains of memory complaints and identifies which complaints are most reflective of objective cognitive problems.     

The relationship of young adolescent Children's Depression Inventory (CDI) scores to their social and cognitive functioning

The relationship of young adolescents' scores on the Children's Depression Inventory (CDI) to subjective and objective indices of their social and cognitive functioning was examined. Subjects were 89 young adolescents (11–15 years old), their parents, and their social studies teachers. The correlations of adolescents' CDI scores with recent school grades, objective ratings of overt social behavior, and measures of adolescent social and cognitive competence as perceived by the adolescent, both parents, and the teacher were examined. CDI scores were significantly and negatively correlated with school grades, behavioral ratings of positive social communication, and adolescent, mother, father, and teacher perceptions of the adolescents' social and cognitive competence. The relationship of these findings to those of other CDI validity studies is discussed.This research was supported, in part, by the William T. Grant Foundation and the University of Georgia's Institute for Behavioral Research.     

Mindfulness-based cognitive therapy for the treatment of current depressive symptoms: a meta-analysis

ABSTRACT

Mindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% confidence interval [CI] [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [?0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [?0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [?0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy.     

Processes of change in a school-based mindfulness programme: cognitive reactivity and self-coldness as mediators

The underlying mechanisms of the effectiveness of mindfulness-based interventions for emotional well-being remain poorly understood. Here, we examined the potential mediating effects of cognitive reactivity and self-compassion on symptoms of depression, anxiety and stress using data from an earlier randomised controlled school trial. A moderated time-lagged mediation model based on multilevel modelling was used to analyse the data. The findings showed that post-treatment changes in cognitive reactivity and self-coldness, an aspect of self-compassion, mediated subsequent changes in symptoms of depression, anxiety and stress. These results suggest that cognitive reactivity and self-coldness may be considered as transdiagnostic mechanisms of change of a mindfulness-based intervention programme for youth.     

Measuring forgiveness: psychometric properties of a new culturally sensitive questionnaire: the Bolton Forgiveness Scale (BFS)

ABSTRACT

Forgiveness is a universal construct. A forgiveness measure should ensure good and diverse cultural representation and inclusivity in its development, validation and usage. The 15-item Bolton Forgiveness Scale (BFS) assesses dispositional forgiveness. Items came from interviews with 53 Nigerian and British people, existing scales and the research literature. Exploratory factor analysis with a student sample (n = 733) was followed by confirmatory factor analysis with a general sample (n = 2,017). This indicated a robust three-factor structure. Factors were, coming to terms and letting go (CLTG), developing positive feelings (DPF) and giving benefit of the doubt (GBD). Scale Validity was established and a new forgiveness definition emerged as a process that involves developing and strengthening the capacity to give benefit of the doubt that enables the offended come to terms with and let go of hurt with its negative affect thereby giving way gradually to positive feelings towards the transgressor.     

Development of a cognitive function test using virtual reality technology: examination in healthy participants

We developed a virtual reality test to assess the cognitive function of Japanese people in near-daily-life environment, namely, a virtual shopping test (VST). In this test, participants were asked to execute shopping tasks using touch panel operations in a “virtual shopping mall.” We examined differences in VST performances among healthy participants of different ages and correlations between VST and screening tests, such as the Mini–Mental State Examination (MMSE) and Everyday Memory Checklist (EMC). We included 285 healthy participants between 20 and 86 years of age in seven age groups. Therefore, each VST index tended to decrease with advancing age; differences among age groups were significant. Most VST indices had a significantly negative correlation with MMSE and significantly positive correlation with EMC. VST may be useful for assessing general cognitive decline; effects of age must be considered for proper interpretation of the VST scores.     

The Strategy and Attribution Questionnaire: Psychometric properties of a Lithuanian translation in an adolescent sample

The present study provides a preliminary validation of the Lithuanian version of the Strategy and Attribution Questionnaire (SAQ, Nurmi, et al., 1995), a self-reported measure of social and cognitive behavioral strategies. An attempt to validate SAQ subscales was made by correlating them with the Youth Self-Report (Achenbach, 1991) and school grades. This was done with a sample of 14- to 17-year-old adolescents (N= 734). The results showed that although internal consistency reliabilities were good, they were lower when compared with the original version of SAQ. The SAQ subscales were moderately associated with various validity criteria, such as anxiety/depression, withdrawal, social problems and somatic complaints and school grades. Results also showed moderate correlations between similar strategic components across achievement and affiliative situations. The results provide preliminary evidence for concurrent validity of the Lithuanian version of SAQ.     

Efficacy of brief guided self-help cognitive behavioral treatment for perfectionism in reducing perinatal depression and anxiety: a randomized controlled trial

Perfectionism has been proposed as a transdiagnostic process that maintains depression and anxiety through shared cognitive and behavioral processes. The purpose of this study was to investigate the efficacy of a brief, guided cognitive behavioral treatment (CBT) for perfectionism delivered via a self-help booklet in reducing perfectionism and symptoms of depression and anxiety during the antenatal period. Pregnant women in their third trimester were randomly allocated to self-help (n = 30) or waitlist control (n = 30). There were significant reductions in perfectionism and symptoms for participants who received CBT for perfectionism from pre- to post-treatment, which were maintained at 3-month follow-up, while the waitlist control group demonstrated no significant changes. Path analysis demonstrated a significant indirect effect of treatment condition on post-treatment depression and anxiety scores via perfectionism, controlling for pre-treatment scores, suggesting changes in perfectionism were associated with decreases in symptoms. The findings suggest that it would be useful for future research with larger samples to further investigate the efficacy of CBT for perfectionism for perinatal depression and anxiety.     

Adult attachment styles and cognitive vulnerability to depression in a sample of undergraduate students: the mediational roles of sociotropy and autonomy

We analysed the mediational role of the personality dimensions of sociotropy and autonomy in the relationship between certain styles of attachment and depressive symptoms. In order for us to do so, a group of university students filled out the Beck Depression Inventory (BDI), the Revised Personal Style Inventory (PSI-II) and the Relationship Questionnaire (RQ). Individuals having attachment styles with a negative model of self (preoccupied and fearful) obtained significantly higher scores in the BDI than those having attachment styles with a positive model of self (secure and dismissing), which coincides with previous research. We followed the standard procedure of Baron and Kenny of linear regression in order to perform the mediational analyses. The preoccupied attachment style-depressive symptoms relationship was mediated by sociotropy. It was also found that autonomy exerted a significant mediational effect on the relationship between the fearful attachment style and depressive symptoms. These results are consistent with the notion that insecure attachment predisposes individuals to the development of depressogenic personality styles. Thus, the findings of the present study contribute to improving the understanding of the factors involved in the development of vulnerability to depression. Furthermore, the results point out the importance of evaluating both attachment style and sociotropy/autonomy personality dimensions for the treatment of depressive patients.     

Estimation of premorbid cognitive function based on word knowledge: the Swedish Lexical Decision Test (SLDT)

In clinical neuropsychology, the present status of a patient is evaluated in relation to the assumed premorbid status. However, in Sweden, existing methods to assess premorbid status are far from optimal. In the present study, the design and evaluation of a Swedish Lexical Decision Test (SLDT) for premorbid global cognitive function (i.e., premorbid intelligence) is described. The design was based on the empirical finding that, in general adult population, word knowledge is strongly associated with measures of global cognitive functioning. Linear stepwise regression analysis demonstrated that SLDT findings accounted for 48% of the variance of global cognitive function as assessed by the Full Scale Intelligence Quotient (FSIQ) from the Wechsler Adult Intelligence Scale Revised (WAIS-R). Demographic variables alone accounted for 31% and a combination of SLDT results and demographics accounted for 60%. Psychometric properties are presented using data from 109 healthy individuals stratified according to age, gender, and level of education. In addition, a case of Alzheimer's disease is presented to illustrate the relationship between SLDT performance and cognitive function. Finally, the theoretical foundation for the relationship between word knowledge and global cognitive function is discussed.     

Effect of cognitive bias modification-memory on depressive symptoms and autobiographical memory bias: two independent studies in high-ruminating and dysphoric samples

Memory bias is a risk factor for depression. In two independent studies, the efficacy of one CBM-Memory session on negative memory bias and depressive symptoms was tested in vulnerable samples. We compared positive to neutral (control) CBM-Memory trainings in highly-ruminating individuals (N?=?101) and individuals with elevated depressive symptoms (N?=?100). In both studies, participants studied positive, neutral, and negative Swahili words paired with their translations. In five study–test blocks, they were then prompted to retrieve either only the positive or neutral translations. Immediately following the training and one week later, we tested cued recall of all translations and autobiographical memory bias; and also measured mood, depressive symptoms, and rumination. Retrieval practice resulted in training-congruent recall both immediately after and one week after the training. Overall, there was no differential decrease in symptoms or difference in autobiographical memory bias between the training conditions. In the dysphoric but not in the high-ruminating sample, the positive training resulted in positive autobiographical bias only in dysphoric individuals with positive pre-existing bias.

We conclude that one session of positive retrieval-based CBM-Memory may not be enough to yield symptom change and affect autobiographical memory bias in vulnerable individuals.     

The impact of religious cognitive behavioural therapy (RCBT) on general health among Iranians

The aim of this study was to determine the efficacy of religious cognitive behavioural therapy (RCBT) on general health among Iranians. This study was a randomised, single-blinded clinical trial from April 2017 to October 2017. One hundred forty-four Yazd citizens were selected using a cluster sampling method and randomly assigned to experimental or control groups. The experimental groups received 10 sessions of RCBT, lasting 45 minutes once a week and the control group remained on the waiting list. The results showed that mean general health scores in the experimental groups were significantly lower than those in the control group on the post-test. RCBT had the most positive impact on somatic symptoms, anxiety/insomnia, social dysfunction, depression, and mental health. Based on these findings RCBT can be considered a significant and effective practical therapy for improving both general and psychological health.     

When less is more: Psychometric properties of Norwegian short‐forms of the Ambivalent Sexism Scales (ASI and AMI) and the Illinois Rape Myth Acceptance (IRMA) Scale

This paper reports on the development and the psychometric properties of short forms of Ambivalent Sexism Scales toward women (ASI; Glick & Fiske, 1996) and men (AMI; Glick & Fiske, 1999), and a scale measuring rape stereotypes (IRMA; McMahon & Farmer, 2011). The short form AMI/ASI were applied for examining gender and educational differences in university students (N = 512) and in high school students (N = 1381), and for predicting individual differences in rape stereotypes in the latter. The short forms demonstrated good to excellent psychometric properties across samples of emerging adults. Relative to female students, male students reported markedly more hostility toward women and more stereotypical beliefs about rape. Despite sampling from a highly gender egalitarian and secular culture, these gender differences are on a par with those reported internationally. Rape stereotypes were predicted by sexism in high school students. Additional predictors were educational program, relationship status, and acceptance of derogatory sexual slurs. The paper questions the validity of separate constructs for benevolent sexism toward women versus men. The short form versions of the scales may substitute the original versions in future research, and help prevent attrition while measuring the same constructs.     

The impact of cognitive interventions on cognitive symptoms in idiopathic Parkinson’s disease: a systematic review

This systematic review addressed efficacy of cognitive stimulation (CS), cognitive training (CT), and cognitive rehabilitation (CR) to improve cognitive functions in Parkinson’s disease (PD) with (PD-MCI) and without mild cognitive impairment (PD-H). Five databases were searched. Twelve CT, four CS, and a combination of CT with CR were found. PD-H benefited from CT or CS compared to active or passive controls in 42.1% of cognitive tests, and in 33.3% of psychological and functional measures. PD-MCI alone, compared with controls, only improved in 6.9% of cognitive measures after CT. PD-H and PD-MCI, alone or together, somehow improved information processing speed, attention, working memory, executive functions, and visual episodic memory. PD-MCI improved better than PD-H in global cognition and planning abilities. The outcomes suggest some efficacy of cognitive interventions in PD. However, small samples, lack of information regarding standardization of interventions, and poor methodological quality limit results validity and prevent firm conclusions.     

The effects of rumination and negative cognitive styles on depression: a mediation analysis

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship between negative cognitive styles and level of depressive symptoms. A total of 115 college students and 38 patients suffering from depressive disorders completed a battery of questionnaires measuring levels of depressive symptoms, brooding, reflection, and negative cognitive styles. The results support the notion that there exist two distinct dimensions of rumination and that, of the two, it is brooding and not reflection that mediates the relationship between negative cognitive styles and depression and contributes to its negative outcomes.     

负性情绪在冲突适应中的作用机制：分离与整合视角

负性情绪如何影响冲突适应一直以来受到领域内研究者们的广泛关注。根据负性情绪产生的源头(冲突外部操纵vs.冲突内部固有), 对于该问题的论述可以分别从认知与情绪的分离与整合视角展开。分离视角下, 操纵于冲突之外的负性情绪(外部负性情绪)独立于冲突加工过程, 通过情绪加工系统或个体自身的动机/唤醒水平影响冲突适应。近些年来的研究发现冲突加工自动产生负性情绪(固有负性情绪), 寓示着认知冲突与负性情绪间的内在关联, 固有负性情绪因此可被视作诱发冲突适应的另一个有效来源。整合视角下, 操纵于冲突内部的(固有)负性情绪高度整合于冲突加工过程, 其功能与冲突信息类似, 通过内在地促进目标导向行为直接诱发冲突适应。对这一主题的论述加深了我们对负性情绪如何作用于冲突适应过程的理解, 也为探索认知与情绪系统的整合过程及作用机制提供了一个全新的视角, 在此基础上, 我们也提出一些未来可行的研究方向。     

Negative problem orientation (Part I): psychometric properties of a new measure

Negative problem orientation, a set of dysfunctional attitudes toward social problem-solving, has increasingly become an important construct in our understanding of deficits in problem-solving ability in daily life. Until recently, no measure was specifically constructed to assess negative problem orientation directly, other than as a subscale in a more global measure of problem-solving ability. The goal of the present study was to translate the French version of the Negative Problem Orientation Questionnaire (NPOQ), and to examine its psychometric properties. The sample consisted of 201 university students who completed five questionnaires assessing psychological distress, pessimism, components of problem-solving ability, and the NPOQ. A unitary factor structure was revealed, accounting for 54.8% of the variance. The NPOQ had excellent internal consistency, good test-retest reliability at 5 weeks, and demonstrated convergent and discriminant validity when measured against self-reported pessimism, depression, anxiety, and problem-solving ability. The findings suggest that the NPOQ is a measure with sound psychometric properties that will be a valuable tool in future research on problem orientation.     

Effects of maternal postpartum depression in a well‐resourced sample: Early concurrent and long‐term effects on infant cognitive,language, and motor development

This study examined early and long‐term effects of maternal postpartum depression on cognitive, language, and motor development in infants of clinically depressed mothers. Participants were 83 mothers and their full‐term born children from the urban region of Copenhagen, Denmark. Of this group, 28 mothers were diagnosed with postnatal depression three to four months postpartum in a diagnostic interview. Cognitive, language, and motor development was assessed with the Bayley Scales of Infant and Toddler Development third edition, when the infants were 4 and 13 months of age. We found that maternal postpartum depression was associated with poorer cognitive development at infant age four months, the effect size being large (Cohen's d = 0.8) and with similar effects for boys and girls. At 13 months of age infants of clinical mothers did not differ from infants of non‐clinical mothers. At this time most (79%) of the clinical mothers were no longer, or not again, depressed. These results may indicate that maternal depression can have an acute, concurrent effect on infant cognitive development as early as at four months postpartum. At the same time, in the absence of other risk factors, this effect may not be enduring. The main weaknesses of the study include the relatively small sample size and that depression scores were only available for 35 of the non‐clinical mothers at 13 months.     

The effect of time constraints and personality facets on general cognitive ability (GCA) assessment

General cognitive ability (GCA) is a recognized construct for predicting job performance and capacity to learn. However, it has recently been argued that the time constraints under which GCA is assessed might provoke test anxiety, which negatively biases GCA scores. This can then lead to erroneous rejection of qualified candidates in personnel hiring contexts. This paper aimed to investigate: (1) to what extent candidates’ GCA scores increase when tested without time constraints and the ability of this GCA score to predict job performance; and (2) the personality characteristics that hinder GCA test performance under time constraints. Results from two field studies conducted in an actual personnel selection context partially confirmed the hypotheses. They revealed that, aside from the improvement of all candidates’ GCA scores when time constraint was removed, only GCA assessed without time constraints predicts job performance. Furthermore, while all candidates’ scores were influenced by the time constraint condition, individuals who are anxious, low-impulse, low value-questioning and deliberating are more penalized by the time constraint condition of such testing and, thus, are more likely to be erroneously eliminated in a selection process.
