Facilitators and Barriers of Adherence to Multi-Disease Exacerbation Action Plans in COPD Patients – A Qualitative Study

Whereas exacerbation action plans to self-manage Chronic Obstructive Pulmonary Disease (COPD) significantly improve health outcomes, patients’ adherence to those action plans is often poor. This study aimed to identify facilitators and barriers of adherence to tailored multi-disease exacerbation action plans. We also explored patients’ perspectives toward disease management roles. Individual semi-structured interviews were conducted with a sample of COPD patients who completed a Dutch-Australian self-management intervention evaluating tailored exacerbation action plans for COPD and relevant comorbidities. Interviews were thematically analyzed using a deductive approach guided by the Capability, Opportunity and Motivation of Behavior (COM-B) model. In 2016, ten patients (5 Australian; 5 Dutch; 6 men; age 59-83 years) were interviewed at the end of their one-year follow-up. Facilitators of adherence included improved patients’ comprehension of disease and treatment, positive feelings about the intervention, improved self-confidence, and professional support. Barriers included difficulties to recognize symptoms, dislike toward daily symptom monitoring, negative feelings about the intervention, negative mood state, and complexity of symptom diaries and action plans. Patients indicated three distinctive perspectives of their own and their healthcare professional’s role in their disease management: 1) patients felt mainly responsible; 2) patients felt shared responsibility with their healthcare professional; and 3) patients felt not responsible as they perceived their healthcare professional to be mainly responsible. We successfully used the COM-B model as a guide to identify facilitators and barriers of patients’ adherence to multi-disease exacerbation action plans. Improving patients’ adherence in future self-management interventions by targeting specific facilitators or barriers should be considered.

Effect of Taste-Induced Mood on ERP and Emotional Assessment of Images.

Tastes affect the body and our emotions. We used tasteless, sweet, and bitter stimuli to induce participants' moods, and we examined the effect of mood on an emotional evaluation of pleasant, neutral, and unpleasant images using event-related potentials, N2, N400, and late positive potential (LPP), which reflect emotional evaluation in the brain. The results indicated that mood valence was most positive for sweetness and most negative for bitterness. Moreover, there was no significant mood effect on subjective valence ratings of emotional images. Furthermore, the N2 amplitude, which is related to the early semantic processing of preceding stimuli, was unaffected by the taste induced mood. In contrast, we found that the N400 amplitude, which is related to the mismatch of emotional valence between stimuli, increased significantly for unpleasant images when participants were in a positive rather than negative mood state. Also, the LPP amplitude, which is related to the emotional valence of images, showed only the main effect of the images' emotional valence. The N2's results suggest that the early semantic processing of taste stimuli might have had a negligible impact on emotional evaluation because taste stimuli minimize semantic processing that accompanies mood induction. In contrast, the N400 reflected the effects of the induced mood, and the LPP reflected the impact of the valence of emotional images. The use of taste stimuli to induce mood revealed different brain processing of taste-induced mood effects on emotional evaluation, including N2's involvement in semantic processing, N400's involvement in matching emotions between mood and stimuli, and LPP's involvement in subjective evaluations of stimuli.

Effects of nature sounds on the attention and physiological and psychological relaxation

This study aims to verify the effects of nature sounds on attention, and physiological and psychological relaxation. Twenty-six university students (mean age: 21.5 ± 1.9 years) participated in this study, and the experiment was conducted with one person at a time. A mixed sound of valley water and birds in a forest environment was used as the nature sound, and a road traffic sound was used as the urban sound (control). The participants performed the following steps: (1) closed their eyes and rested for 1 min; (2) opened their eyes and completed attention tasks while hearing nature or urban sounds for 1 min; (3) closed their eyes again and rested while hearing the same sound for 1 min. We used Harris and Harris grid for the attention task. We measured the participants’ oxy-hemoglobin concentration, heart rate variability, and heart rate for physiological evaluation, and used semantic differential method, and profile of mood states for psychological evaluation. As a result, ① There was no significant difference in the results of the attention task; however, the scores were slightly higher when hearing nature sound. ② The oxy-hemoglobin concentration and heart rate was lower, and parasympathetic nerve activity was enhanced when hearing nature sound than when hearing urban sound. ③ Once participants heard nature sound, they felt more comfortable, relaxed, and natural, and the negative mood state was lower, while the positive mood state was higher than urban sound. This suggests that hearing nature sounds may be an effective way to relieve stress in everyday life.

Mindfulness-based stress reduction combined with early cardiac rehabilitation improves negative mood states and cardiac function in patients with acute myocardial infarction assisted with an intra-aortic balloon pump: a randomized controlled trial.

To investigate the clinical effects of mindfulness-based stress reduction (MBSR) intervention combined with early cardiac rehabilitation (CR) on patients with acute myocardial infarction (AMI) assisted with an intra-aortic balloon pump (IABP). A total of 100 AMI patients with IABP assistance due to hemodynamic instability at Wuhan Asia Heart Hospital were enrolled in the study. The participants were divided into two groups using the random number table method (n = 50 each group). Patients receiving routine CR were assigned to the CR control group, while patients receiving MBSR plus CR were assigned to the MBSR intervention group. The intervention was performed twice a day until the removal of the IABP (5-7 days). Each patient's level of anxiety/depression and negative mood state were evaluated before and after intervention using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and profiles of mood state scale (POMS). The results of the control and intervention groups were compared. IABP-related complications and left ventricular ejection fraction (LVEF), measured with echocardiography, were also assessed and compared between the two groups. The SAS, SDS, and POMS scores were lower in the MBSR intervention group than in the CR control group (P < 0.05). There were also less IABP-related complications in the MBSR intervention group. LVEF was significantly improved in both groups, but the degree of LVEF improvement was more significant in the MBSR intervention group than in the CR control group (P < 0.05). MBSR combined with early CR intervention can assist in alleviating anxiety, depression, and other negative mood states, reduce IABP-related complications, and further improve cardiac function in AMI patients with IABP assistance.

0173 Improving Well-being by Changing the Shiftwork Schedules at U.S. Navy Watchfloors

Abstract Introduction Watchfloors provide around-the-clock information, intelligence, and technical support to the U.S. military. Active-duty service members (ADSMs) working on these 24/7 watchfloors stand watches to include night shifts and/or frequent shift rotations. Tailoring shiftwork schedules to optimize individual sleep patterns may reduce the negative effects of shiftwork. The purpose of this study was to test whether a new shiftwork schedule would improve ADSM well-being and sleep. Methods ADSMs (N=79; 83.5% males, 91.2% enlisted, 19 to 54 years of age) participated in a two-phase quasi-experimental longitudinal study to assess well-being and sleep before and after the implementation of a new shiftwork schedule. Both schedules involved three rotating shifts: day shift (0730-1530), evening shift (1320-2330), and night shift (2330-0730). The old schedule had 5 successive days on-shift (5-on/4-off) and the new schedule had 4 successive days on-shift (4-on/4-off). Shifts rotated after every off period. Standardized questionnaires were administered while participants were on the old schedule (study start) and ~5 months after switching to the new schedule. The questionnaires included the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), the Epworth Sleepiness Scale (ESS), and the Profile of Mood States (POMS). Sleep was monitored using wearable devices (ŌURA rings). Results POMS total mood disturbance scores were lower (i.e., better) on the new schedule (p&amp;lt; 0.001), as were several POMS sub-scale scores including tension (p&amp;lt; 0.001), depression (p&amp;lt; 0.001), anger (p=0.014), confusion (p&amp;lt; 0.001), and vigor (p=0.029). There was a statistical trend for a decrease in ISI scores from the old schedule to the new schedule (p=0.067). Sleep duration, PSQI, and ESS scores did not differ between schedules (all p&amp;gt;0.05). Conclusion Implementation of a new shiftwork schedule that was tailored to worker sleep patterns was associated with decreased mood disturbance, improvement in negative mood states (e.g., depression and tension), and reduced insomnia symptom severity. Also, the research team received several anecdotal reports of high levels of worker satisfaction with the new schedule. This study demonstrates the positive real-world effects of using basic sleep and circadian methods to tailor shiftwork schedules to improve the well-being of military personnel. Support (if any)

The Impact of Nursing Handover on Nurses’ Mood

Objective: To estimate the impact of nursing handover on nurses’ mood after the end of the nursing shift report. Methods: A cross-sectional, repeated-measures design study involving a diary questionnaire was conducted during November - December 2019. Data were collected from 125 nurses working in a public hospital in Northern Greece. 375 diaries were returned. Mood change was measured using the UWIST Mood Adjective Checklist instrument that describes three mood factors (Hedonic Tone, Tense Arousal and Energetic Arousal). Results: A significant change in nurses’ mood before and after the nursing handover was reported and more specifically, an increase in positive and a decrease in negative mood state was observed. A change in all mood groups - Hedonic Tone, Tense Arousal and Energetic Arousal was also identified. Nurses with many years of experience who work in internal medicine, increased their Hedonic Tone (P=0.001) and decreased their Tense Arousal (P=0.005). Conclusion: The benefits of nursing handover are long established and is suggested as the most appropriate period of time for nurses to achieve emotional change before leaving from work. Nurses are advised to use the nursing handover as an opportunity to psychologically disengage from work and increase their positive mood.

Impulsivity in amphetamine use disorder: Examination of sex differences.

This study aimed to test whether there are sex differences in the relationship between impulsivity and amphetamine use disorder (AMP). A naturalistic cross-sectional design was used. The Tulsa 1000 study was held in Tulsa, OK, USA. There were two groups in this study: AMP+ (29F, 20M) and AMP- (57F, 33M). This project focuses on data related to impulsivity: UPPS-P impulsive behavior scale and a stop signal task (SST) during functional magnetic resonance imaging (fMRI) recording. Group, sex and their interaction were compared for UPPS-P ratings and SST fMRI and behavioral responses. AMP+ reported higher UPPS-P positive and negative urgency scores (Ps< 0.001; r = 0.56 and 0.51) and displayed greater bilateral insula and amygdala responses across correct SST trials (Ps < 0.001, g range = 0.57-0.81) than AMP-. fMRI results indicated that AMP+ exhibited larger right anterior/middle insula, amygdala and nucleus accumbens signals during successful difficult stop trials than AMP- (Ps< 0.01; g = 0.63, 0.54 and 0.44, respectively). Crucially, two group × sex effects emerged: (a) within females, AMP+ reported larger UPPS-P lack of premeditation scores than AMP- (P < 0.001, r = 0.51), and (b) within males, AMP+ showed greater left middle insula signals than AMP- across correct SST trials (P = 0.01, g = 0.78). Both female and male amphetamine users appear to be characterized by rash action in the presence of positive and negative mood states as well as heightened recruitment of right hemisphere regions during behavioral inhibition. In contrast, planning ahead may be particularly difficult for female amphetamine users, whereas male amphetamine users may need to recruit additional left hemisphere resources during inhibitory processing.

Tell me how you feel, I will tell you what you look at: Impact of mood and craving on alcohol attentional bias in binge drinking.

Alcohol-related attentional bias (AB) is thought to play a key role in the emergence and maintenance of excessive alcohol use. Recent models suggest that AB, classically considered as a permanent feature in alcohol use disorders, is rather modulated by temporary motivational states. We explored the influence of current mood and craving on AB in binge drinking, through a mood induction procedure combined with eye-tracking measures of AB. In Experiment 1, we measured AB (visual probe task with eye-tracking measures) among binge drinkers (n = 48) and light drinkers (n = 32) following positive, negative and neutral mood inductions. Participants reported subjective craving and mood before/after induction. In Experiment 2, we measured AB among the same binge drinkers compared with 29 moderate drinkers following alcohol-related negative, non-alcohol-related negative and neutral mood inductions. In Experiment 1, induced negative mood and group positively predicted subjective craving, which was positively associated with AB. We found no effect of induced positive mood nor a direct mood-AB association. In Experiment 2, the relationships AB presented with both induced negative mood and group were again mediated by craving. Inducing alcohol-related negative mood did not modify the mood-craving association. Alcohol-related AB is not a stable binge drinking characteristic but rather varies according to transient motivational (i.e., craving) and emotional (i.e., negative mood) states. This study provides important insights to better understand AB in subclinical populations and emphasizes the importance of considering motivational and affective states as intercorrelated, to offer multiple ways to reduce excessive alcohol use.

Peer Attachment Style Moderates the Effect of Mood on Creativity.

The present study investigated the moderating role of peer attachment style in the relationship between mood and creativity. An experiment was conducted with a sample of 267 undergraduate students (Mage = 19.85, range = 17-24years). First, participants' peer attachment style was measured, following which positive, neutral, or negative mood was induced; subsequently, two creative tasks were conducted. A MANOVA revealed significant interactions between peer attachment and mood. Specifically, for secure participants, creativity was significantly higher in the positive mood state compared to the neutral and negative mood states; for insecure participants, the effect of positive mood was not pronounced. Moreover, negative mood exerted a significant beneficial effect on the originality dimension for participants with an anxious-ambivalent peer attachment style; they showed higher creativity in the negative mood state than in the neutral or positive mood states. In general, peer attachment style moderated the relationship between mood and creativity; specifically, positive mood was beneficial to creativity among secure persons, and negative mood was beneficial to creativity among anxious-ambivalent persons.

Purchasing Under the Influence of Alcohol: The Impact of Hazardous and Harmful Patterns of Alcohol Consumption, Impulsivity, and Compulsive Buying.

The current research examined how hazardous and harmful patterns of alcohol consumption, problematic online shopping when drinking alcohol, impulsivity, and compulsive buying were associated with and predicted the frequency of making purchases while under the influence of alcohol. A sample of American adults between the ages of 25 and 64 who reported having at least one drink per week over the past 6months were surveyed. Regression-based path modeling revealed for those who made online purchases while moderately intoxicated, hazardous and harmful patterns of drinking alcohol and, problematic online shopping when drinking alcohol, predicted the frequency of making purchases while intoxicated. For those who made online purchases while heavily intoxicated, hazardous and harmful patterns of drinking alcohol, impulsivity, problematic online shopping when drinking alcohol, and compulsive buying predicted the frequency of making purchases while intoxicated. We explain our findings by suggesting individuals engage in frequent drunk purchases because they are motivated to alleviate their negative mood states.

A comparison of the impact of exposure to fit ideal and non-fit ideal body shapes in fitspiration imagery on women

Previous research indicates a negative impact of exposure to fitspiration on women's mood, self-esteem, and body satisfaction. Fitspiration typically features thin and toned bodies, but there is some variation in the body types shown, which may influence its effects on viewers. Participants (N = 605women) were randomly allocated to view fit ideal, non-fit ideal, or neutral control images from Instagram, and completed state measures of appearance self-esteem, self-objectification, body satisfaction, and negative mood before and after image exposure. Women in the fitspiration conditions also reported level of state appearance comparison with women depicted and how inspired they were to do more exercise. Fit ideal and non-fit ideal images had a negative effect on body satisfaction. However, participants in the non-fit ideal condition showed an increase in state self-esteem and a decrease in state negative mood following image exposure, in contrast to the fit ideal condition. Condition did not have an impact on state self-objectification and there was no difference between fitspiration conditions in how inspired participants felt to do more exercise. State appearance comparison was correlated with change in self-esteem, negative mood, body satisfaction scores and with how inspired individuals felt to exercise. Small effect sizes and limitations indicate that replication of findings is required. However, the effects of viewing fitspiration imagery may depend on thinness and muscle tone of models shown, and level of comparison with people portrayed.

Alleviation of Cocaine Withdrawal and Pertinent Interactions between Salvinorin-Based Antagonists and Kappa Opioid Receptor.

The kappa opioid receptor (KOR) is involved in the regulation of both the reward and mood processes. Recent reports find that the use of drugs of abuse increases the production of dynorphin and the overall activation of KOR. Long-acting KOR antagonists, such as norbinaltorphimine (nor-BNI), JDTic, and 5'-guanidinonaltrindole (GNTI), have been shown to stop depressive and anxiety-related disorders, which are the common side effects of withdrawal that can lead to a relapse in drug use. Unfortunately, these prototypical KOR antagonists are known to induce selective KOR antagonism that is delayed by hours and extremely prolonged, and their use in humans comes with serious safety concerns because they possess a large window for potential drug-drug interactions. Furthermore, their persistent pharmacodynamic activities can hinder the ability to reverse unanticipated side effects immediately. Herein, we report our studies of the lead selective, salvinorin-based KOR antagonist (1) as well as nor-BNI on C57BL/6N male mice for spontaneous cocaine withdrawal. Assessment of pharmacokinetics showed that 1 is a short-acting compound with an average half-life of 3.75 h across different compartments (brain, spinal cord, liver, and plasma). Both 1 (5 mg/kg) and nor-BNI (5 mg/kg) were shown to reduce spontaneous withdrawal behavior in mice, with 1 producing additional anti-anxiety-like behavior in a light-dark transition test (however, no mood-related effects of 1 or nor-BNI were observed at the current dosing in an elevated plus maze or a tail suspension test). Our results support the study of selective, short-acting KOR antagonists for the treatment of psychostimulant withdrawal and the associated negative mood states that contribute to relapse. Furthermore, we identified pertinent interactions between 1 and KOR via computational studies, including induced-fit docking, mutagenesis, and molecular dynamics simulations, to gain insight into the design of future selective, potent, and short-acting salvinorin-based KOR antagonists.

Alcohol Use Severity, Anger and Drinking Motives among Firefighters

Background: Firefighters represent an understudied population with high rates of hazardous alcohol use and alcohol use disorder. This population is also at an increased risk of mental health disorders and related symptoms such as anger. Anger is a relatively understudied negative mood state with clinical relevance to alcohol use among firefighters. Anger is associated with greater alcohol use and may spur more approach-motivated reasons for drinking compared to other negative emotions. Objectives: This study sought to examine: 1. whether anger significantly contributes to alcohol use severity in firefighters above and beyond general negative mood; 2. which of four validated drinking motives (e.g., coping, social, enhancement and conformity) act as moderators in the relationship between anger and alcohol use severity in this population. The current study is a secondary analysis of data from a larger study examining health and stress behaviors among firefighters (N = 679) at a large urban fire department in the southern United States. Results: Results revealed that anger was positively associated with alcohol use severity, even after controlling for general negative mood. Further, social and enhancement motives for drinking were significant moderators of the relationship between anger and alcohol use severity. Conclusions: These findings identify anger specifically as an important factor to be considered when assessing alcohol use in firefighters, especially those who are drinking to make social experiences more enjoyable or to enhance their mood. These findings can be used to inform more specialized interventions for alcohol use by targeting anger more specifically in firefighters and other male-dominated first-responder populations.

Association Between Hearing Loss and Multiple Negative Emotional States in the USHispanic Population.

Hearing loss (HL) has been linked to commonly studied detrimental mood states, such as loneliness and depression. However, its relationship with other negative emotions remained largely unstudied. We explore the association between HL and anxiety, anger, hostility, poor self-esteem, and pessimism in a national cohort of USHispanic adults. Cross-sectional study. Multicentered USnational epidemiologic study (Hispanic Community Health Study). Subjects were ages 18 to 75 with completed audiometric and emotional survey data. Multivariable regressions controlling for age, gender, and education were conducted to analyze the association between HL, measured by 4-frequency pure-tone average (PTA), and emotional states. States included anxiety (Spielberger Trait Anxiety Scale-10), anger (Spielberger Trait Anger Scale), hostility (Cook Medley Cynicism Scale-13),poor self-esteem (Self-Esteem Scale-10), and pessimism (Revised Life Orientation Test). A total of 4120 to 4341 participants met inclusion criteria, depending on the specific survey; the average age was 46.7 years (standard deviation [SD] = 13.7), and the average PTA was 13.8 dB (SD = 10.1). Controlling for age, gender, and education, HL was associated with all outcomes. Specifically, for every 10 dB worsening in HL, the anxiety score worsened by 0.41 (0.23-0.60), the anger score worsened by 0.40 (0.22-0.58), the hostility score worsened by 0.16 (0.04-0.27), the self-esteem score worsened by 0.25 (0.12-0.38), and the pessimism score worsened by 0.17 (0.04-0.30) (all p < .01). HL is related to numerous negative mood states beyond loneliness and depression. This includes worse anxiety, anger, hostility, self-esteem, and pessimism. Future studies should investigate whether treating HL improves negative emotional states.

Design and rationale of a pilot randomized clinical trial investigating the use of a mHealth app for sarcoidosis-associated fatigue

Fatigue is the most reported symptom in patients with sarcoidosis (SPs) and is a significant predictor of decreased quality of life that is strongly associated with stress and negative mood states. Few medications exist for treating fatigue in SPs, and outpatient physical rehabilitation programs are limited by availability and cost. Sarcoidosis in the US predominantly impacts minorities and underserved populations who are of working age and often have limited resources (e.g., financial, transportation, time off work) that may prevent them from attending in-person programs. The use of mobile health (mHealth) is emerging as a viable alternative to provide access to self-management resources to improve quality of life. The Sarcoidosis Patient Assessment and Resource Companion (SPARC) App is a sarcoidosis-specific mHealth App intended to improve fatigue and stress in SPs. It prompts SPs to conduct breathing awareness meditation (BAM) and contains educational modules aimed at improving self-efficacy.Herein we describe the design and methods of a 3-month randomized control trial comparing use of the SPARC App (10-min BAM twice daily) to standard care in 50 SPs with significant fatigue (FAS ≥22). A Fitbit® watch will provide immediate heartrate feedback after BAM sessions to objectively monitor adherence. The primary outcomes are feasibility and usability of the SPARC App (collected monthly). Secondary endpoints include preliminary efficacy at improving fatigue, stress, and quality of life. We expect the SPARC App to be a useable and feasible intervention that has potential to overcome barriers of more traditional in-person programs.

The Effect of Sadness on Visual Artistic Creativity in Non-Artists.

The study of the relationships between mood and creativity is long-standing. In this study, the effects of mood states on artistic creativity were investigated in ninety non-artist participants. Mood states were induced by instructing participants to listen to self-selected happy, sad, or neutral music for ten minutes. Then, all participants were asked to make two artistic drawings. To check for mood manipulation, the Profile of Mood States (POMS) was administered before and after listening to the self-selected music. After the mood induction, the negative group reported higher scores than the other two groups in the 'depression' subscale and lower scores than the other two groups in the 'vigour' subscale of the POMS; the positive mood group showed more vigour than the negative mood group. Yet, three independent judges assigned higher ratings of creativity and emotionality to the drawings produced by participants in the negative mood group than drawings produced by participants in the other two groups. These results confirmed that specific negative mood states (e.g., sadness) positively affect artistic creativity, probably because participants are more likely to engage in mood-repairing. Limitations and future research directions are presented.

Probing fMRI brain connectivity and activity changes during emotion regulation by EEG neurofeedback.

Despite the existence of several emotion regulation studies using neurofeedback, interactions among a small number of regions were evaluated, and therefore, further investigation is needed to understand the interactions of the brain regions involved in emotion regulation. We implemented electroencephalography (EEG) neurofeedback with simultaneous functional magnetic resonance imaging (fMRI) using a modified happiness-inducing task through autobiographical memories to upregulate positive emotion. Then, an explorative analysis of whole brain regions was done to understand the effect of neurofeedback on brain activity and the interaction of whole brain regions involved in emotion regulation. The participants in the control and experimental groups were asked to do emotion regulation while viewing positive images of autobiographical memories and getting sham or real (based on alpha asymmetry) EEG neurofeedback, respectively. The proposed multimodal approach quantified the effects of EEG neurofeedback in changing EEG alpha power, fMRI blood oxygenation level-dependent (BOLD) activity of prefrontal, occipital, parietal, and limbic regions (up to 1.9% increase), and functional connectivity in/between prefrontal, parietal, limbic system, and insula in the experimental group. New connectivity links were identified by comparing the brain functional connectivity between experimental conditions (Upregulation and View blocks) and also by comparing the brain connectivity of the experimental and control groups. Psychometric assessments confirmed significant changes in positive and negative mood states in the experimental group by neurofeedback. Based on the exploratory analysis of activity and connectivity among all brain regions involved in emotion regions, we found significant BOLD and functional connectivity increases due to EEG neurofeedback in the experimental group, but no learning effect was observed in the control group. The results reveal several new connections among brain regions as a result of EEG neurofeedback which can be justified according to emotion regulation models and the role of those regions in emotion regulation and recalling positive autobiographical memories.

Negative mood states as a correlate of cognitive performance and self-assessment of cognitive performance in bipolar disorder versus schizophrenia

IntroductionMood states have been reported to manifest a cross-sectional correlation with self-assessment accuracy across functional domains and psychiatric conditions. Ecological momentary assessment (EMA) provides a strategy to examine the momentary course and correlates of mood states. This study tested the association of moods assessed longitudinally with accuracy of immediate self-assessments of cognitive test performance in participants with schizophrenia and bipolar disorder. Methods240 well-diagnosed participants with schizophrenia and bipolar disorder completed a subset of tests from the MATRICS Consensus Cognitive Battery and an immediate self-assessment of cognitive performance. Differences between actual and self-reported performance were used to index the accuracy of self-assessment. Daily smartphone EMA, 3× per day for 30 days, sampled participants´ momentary moods (sad, happy, relaxed, anxious), aggregated into positive affect and negative affect (NA). ResultsBipolar participants had better cognitive performance, but both samples had equivalent mis-estimation. Repeated-measures analyses found that NA did not manifest significant variability over time either between or within participants in the two diagnostic groups. Within-group analyses found that higher average NA was associated with greater mis-estimation and poorer cognitive performance in participants with bipolar disorder, but not in those with schizophrenia. ConclusionNegative moods had a significant association with impairments in self-assessment of cognitive performance in participants with bipolar disorder. Our study did not confirm previous cross-sectional findings of more accurate self-assessment associated with greater NA in schizophrenia. These findings suggest that cross-sectional assessments, particularly self-reports, may lead to different results than aggregated data from longitudinal evaluations.

Reminiscence Activates the Frontal Lobe and Ameliorates Negative Mood States in Cognitively Intact Older Adults

Reminiscence Activates the Frontal Lobe and Ameliorates Negative Mood States in Cognitively Intact Older Adults
