34 Variability in RBANS Performance and Neurocognitive Impairment in Older Adults with Cognitive Concerns

Objective:Risk factors that contribute to brain pathology and cognitive decline among older adults include demographic factors (e.g., age, educational attainment), genetic factors, health factors, and depression (Plassman et al., 2010). Variability within an individual’s performance across cognitive tasks is referred to as dispersion (Hultsch et al., 2002), which appears sensitive to subtle cognitive impairments associated with neurodegenerative pathology in older adults (Bangen et al., 2019; Kälin et al., 2014). Thaler and colleagues (2015) found that dispersion across domains of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was a useful indicator of cognitive changes associated with cardiovascular disease and mortality. Also, research by Manning and colleagues (2021) found that elevated ratings of depression and anxiety in older adults was associated with greater dispersion across neuropsychological testing. The present study aimed to replicate findings that greater dispersion in neuropsychological performance is associated with impaired neurocognitive performance and greater self-reported depression among older adults who present for neuropsychological evaluation with cognitive concerns.Participants and Methods:Neuropsychological testing data was obtained from a university hospital. Chart reviews were conducted on 369 participants who met initial criteria (60 years or older with testing data from the RBANS Form A, Wechsler Test of Adult Reading, and Geriatric Depression Scale [GDS]). Retrospective analyses were conducted on a final sample of 293 participants from 60 to 94 years old (Mage = 74.41, SDage = 7.43; 179 females, 114 males). Diagnoses were used for group comparisons between cognitively intact individuals with subjective cognitive complaints (SCC, n = 49), persons with Mild Neurocognitive Disorder (mND, n =137), and persons with Major Neurocognitive Disorder (MND, n = 107).Results:As expected, results indicated that higher dispersion was related to lower Total RBANS Scores (r = -0.54, p < .001) and significant differences across diagnostic groupings (F(2, 289) = 29.19, p < 0.001; SCC, mND, MND) indicated that variability in performance was an indicator of greater neurocognitive impairment. Contrary to expectations, greater dispersion was very weakly associated with lower reported depressive symptomatology (r = -0.13, p = 0.03). A three-stage hierarchical linear regression was conducted with the RBANS Coefficient of Variation (CoV) as the dependent variable and three predictor variables (Age, Total RBANS, Total GDS). The regression analysis results indicated that age was not a significant predictor, but both Total RBANS and GDS Scores were. The most important predictor was Total RBANS Scores which uniquely explained 21% of the variation in dispersion.Conclusions:This study adds to the current literature regarding the clinical utility of dispersion in neuropsychological performance as an indicator of early and subtle neurocognitive impairment. Depressive symptom reporting was expected to help predict the degree of variability, but this factor was only weakly associated with the RBANS CoV.Limitations of this study include its retrospective use of archival data and the restricted range on some variables of interest. Further research is needed to examine the relative utility of different measures of dispersion and why increased cognitive performance variability is related to neurocognitive impairment and decline.

Predicting Depression in Dementia Caregivers: Do Religious/Spiritual Struggles Play a Role?

Using a stress process framework model, this study is the first to comprehensively examine the role that religious/spiritual struggles play in the lives of informal dementia caregivers. A convenience sample of 156 informal dementia caregivers completed a scale measuring six domains of religious/spiritual struggles, as well as other measures of primary stressors, background/contextual variables, and mental health outcome (depression). Overall levels of religious/spiritual struggle were low, but 26 percent of the sample were classified as possible cases of clinically significant religious/spiritual struggle for at least one of the six domains. Of this group, 49 percent acknowledged struggles with ultimate meaning. Religious/spiritual struggles predicted greater self-reported depression over and above number of care recipient problem behaviors (primary stressor), caregiver sex, and caregiver personality (i.e., emotional stability). Although no individual domain of religious/spiritual struggle emerged as most salient, caregivers reported significantly more ultimate meaning struggles than demonic or interpersonal struggles. These findings support the growing body of research suggesting that religious/spiritual struggles serve as a secondary stressor, adding predictive power to background/contextual factors and to primary stressors for informal dementia caregiver mental health outcomes. Further research in this area may advance efforts to better equip both secular and religious professionals to provide evidence-based counsel to informal dementia caregivers.

Depression affects the recovery trajectories of patients with distal radius fractures: A latent growth curve analysis.

BackgroundDistal radius fractures (DRFs) are common and can lead to substantial pain and disability. Most people recover in six months, but some experience persistent pain and disability for one year or longer after injury. Therefore, it is important to understand the factors that can help predict poor recovery. ObjectiveTo identify recovery trajectories in DRF patients and to determine the factors that can help predict poor recovery. MethodsRecovery was assessed in 318 patients using the Patient-Rated Wrist Evaluation scale at baseline, three, six, and 12 months. Demographic information was collected in addition to the Self-Administered Comorbidity Questionnaire, from which data regarding depression were extracted. Latent growth curve analysis (LGCA) was used to identify the recovery trajectories. Comparisons of proportion between the emergent classes were then conducted using chi-square and Kruskal-Wallis tests. ResultsThe LGCA revealed three distinct trajectories (rapid-recovery: (69%), slow-recovery: (23%), and non-recovery: (8%) as the best fit to the data. The proportion of people with depression was significantly greater in the non-recovery class (24%) compared to the slow (16%, p = 0.04) and rapid-recovery (8%, p = 0.03) classes. Additionally, the proportion of females were significantly lower in the non-recovery (64%, p = 0.03) compared to the slow (85%, p = 0.03) and the rapid-recovery classes (81%, p = 0.048). ConclusionRecovery from DRF was best described using three different trajectories. Greater self-reported depression and a lower proportion of females in the non-recovery class were distinguishing factors between the classes. Patients who appear to be in slow-recovery or non-recovery classes may be followed more closely.

Buffering against maladaptive perfectionism in bipolar disorder: The role of self-compassion

BackgroundMaladaptive perfectionism is a transdiagnostic risk and maintaining factor for a range of mental health conditions, including bipolar disorder (BD). Self-compassion represents a potential protective factor against maladaptive perfectionism, however no studies to date have examined the relationship of these constructs in BD. The aim of the present study was to examine associations between maladaptive perfectionism, self-compassion and symptoms among individuals with BD. MethodsBaseline data were collected from 302 participants with a DSM-IV diagnosis of BD participating in an international randomised controlled trial. Participants completed measures of maladaptive perfectionism, self-compassion, symptom severity and emotion regulation difficulties. Clinician-administered measures of depression and mania severity were additionally collected. Correlation and mediation analyses were conducted. ResultsMaladaptive perfectionism was positively associated with depression, anxiety and emotion regulation difficulties. Lower levels of self-compassion correlated with greater self-reported depression, anxiety and emotion regulation difficulties. Self-compassion partially mediated relationships between maladaptive perfectionism, depression, anxiety and emotion regulation difficulties. LimitationsThe cross-sectional design limits conclusions about causal relationships between study variables. Results may not be generalizable to other BD populations. The role of maladaptive perfectionism and self-compassion in elevated mood states of BD remains unclear. ConclusionSelf-compassion represents one mechanism through which maladaptive perfectionism influences symptoms of depression, anxiety and emotion regulation difficulties in BD. Self-compassion represents a modifiable treatment target; individuals with BD exhibiting maladaptive perfectionistic tendencies may benefit from interventions fostering self-compassion.

Discriminative delay Pavlovian eyeblink conditioning in veterans with and without posttraumatic stress disorder

Background Impaired eyeblink (EB) classical conditioning using a delay paradigm has previously been shown in combat veterans, as well as in a group of depressed adults, compared to normal individuals. Significant deficits in immediate memory (IM) in combat PTSD+ veterans, compared to normal controls, have also been previously shown, but these differences became non-significant after controlling for level of self-reported depression. Furthermore, EB conditioning has been shown to be significantly correlated with heart rate variability (HRV) in normal adults. The present study examined how depression (self-reported), IM, and resting HRV are related to discriminative delay classical EB conditioning in veterans with and without PTSD. Method Three groups of subjects (combat PTSD+, combat PTSD−, and non-combat PTSD−) were assessed for self-report of depression and anxiety, as well as IM and HRV. Subjects received a single session of discriminative EB classical conditioning in which the conditioned stimulus (CS) was a light signal (either red or green) compounded with a tone. On CS+ trials, the light-tone compound stimulus co-terminated with a corneal airpuff (unconditioned stimulus, US), thus producing a delay paradigm. On CS− trials the appropriate light-tone stimulus was presented but not followed by the airpuff US. EB amplitude and frequency were recorded. Results PTSD+ subjects had greater self-reported depression and anxiety scores than the two control groups, as well as lower scores on a measure of IM. However, the IM difference was not significant after the effects of self-reported depression and anxiety were controlled. EB CR amplitude was significantly greater to CS+ than CS− for all three groups. EB amplitude to both the US (airpuff) and the CS+ declined over trials, but was significantly lower in the combat PTSD+ group compared to the combined PTSD− groups. Subjects who reached an EB CR acquisition criterion had significantly greater scores on IM than those who did not reach criterion. Factor analysis of the entire data set revealed four factors corresponding to (1) self-reported depression and anxiety, (2) IM, (3) HRV, and (4) EB amplitude. EB frequency was significantly predicted by IM and HRV. Conclusions These data extend our previous results by showing deficits in EB conditioning among combat PTSD+ veterans that were associated with lower IM and resting HRV, but were not associated with self-report of depression.

Cigarette Smoking and Long-Term Alcohol and Drug Treatment Outcomes: A Telephone Follow-Up at Five Years

This prospective study examined the relationship between cigarette smoking and five-year substance abuse treatment outcomes. Of 749 individuals who began private outpatient treatment, 598 (80%) were re-interviewed by telephone at five years. At five-year follow-up, 53% reported smoking cigarettes in the prior 30 days. Smokers were less likely to be abstinent from alcohol and drugs in the prior 30 days (48.3% vs. 64.0%), and had higher Addiction Severity Index (ASI) scores in employment, alcohol, drug, psychiatric, and family/social problems; worse self-reported health; and greater self-reported depression. Findings inform understanding of long-term substance abuse treatment outcomes and potential service needs of smokers.

Social cognitive complexity and depression: cognitive complexity moderates the correlation between depression self-ratings and global self-evaluation.

The authors studied the psychometric characteristics of a standardized data-collection method for assessing the complexity of an individual's cognitions about self and other people (social cognitive complexity). A total of 437 college undergraduates were assessed using this method and concurrently assessed for depression, self-deception, impression management, self-esteem, and positive/negative affectivity. It was found that a measure of overall social cognitive complexity was internally consistent and demonstrated concurrent and discriminant validity. In particular, a composite measure of the complexity of both positive and negative cognitions of self and other was associated with greater self-reported depression, after controlling for the other variables studied (, impression management). It was also found that social cognitive complexity moderated the degree of global self-evaluation in self-reported depression, such that global self-evaluation accounted for a considerably higher amount of the variance of depression in low-complex individuals than it did in high-complex individuals.

Speed of memory scanning is not affected in early HIV-1 infection.

Thirty-seven nondemented HIV-seropositive and 17 seronegative control subjects were administered the Sternberg speed of memory scanning task, a procedure frequently employed to study mental slowing in patients with subcortical dementing disorders. Experimental and control subjects did not differ in speed of memory scanning, as indexed by the slopes of set size-reaction time functions, nor on mean 0-intercepts for the RT functions, which index stimulus detection and motor response time. Intercept values were significantly greater for subjects with a positive alcohol abuse history and for subjects with greater self-reported depression, but slopes were not significantly correlated with substance abuse history or psychological distress. Cognitive slowing in early HIV-1 infection is not a nonspecific effect observed across all measures of information processing speed. Underlying component functions measured must be carefully considered when selecting reaction time tasks for study with HIV-seropositive subjects. The term "subcortical" dementia may be too general a descriptor, and RT task performance may provide an alternative basis for classification of dementia types.

Brief group psychoeducation for bulimia nervosa. II: Prediction of clinical outcome

Forty-one subjects with bulimia nervosa completed a brief intervention that was designed to promote symptom management. A wide variety of clinical and psychometric variables were examined for their predictive utility in determining the clinical outcome of subjects after treatment. The following pretreatment variables were most strongly associated with a poor outcome: greater self-reported depression, higher frequency of vomiting, and a history of low adult body weight. Contrary to expectations, pretreatment levels of self-reported borderline organization were unrelated to outcome. It is suggested that subject by treatment interactions may partially account for the lack of robust prognostic factors which typifies the current treatment literature on bulimia nervosa.
