RESUMO

Community engagement is important for research, yet many researchers do not routinely seek feedback from people with lived experience. A key barrier to this engagement is that the resources required to create an advisory board may be unavailable to individual investigators, and creating an advisory board for a single study may often be impractical. In this column, the authors describe how to create a standing research advisory board that can serve as a shared resource for researchers and community members and provide a psychosis research advisory board example to aid discussion.

RESUMO

Evidence-based interventions vary in effectiveness for individuals with depression, which has a large public health burden. Readiness for change or treatment can be an important individual difference predictor of depression outcomes. To inform public service initiatives targeting readiness for treatment, characterizing readiness across settings and levels of care is key. However, limited data exist on the role of readiness for treatment in acute psychiatric settings and in particular, partial hospital programs which are key points in the continuity of inpatient and outpatient care. The present study assessed readiness for treatment in terms of importance, confidence, and motivation to engage in a partial hospital program and tested whether higher levels of readiness were associated with better treatment outcomes among clients with depression. Participants (N = 192) with major depressive disorder rated their readiness for treatment (Readiness Rulers), depression (Patient Health Questionnaire-9), and global improvement (Clinical Global Impression Scale-Improvement Self-Report) while enrolled in a partial hospital program. Generalized linear regression models assessed the effect of baseline readiness on outcomes at discharge, adjusted for baseline level of the outcome, age, sex, race, and ethnicity. Greater baseline readiness predicted reduced depression and better global improvement at discharge. Higher confidence and motivation to engage in treatment, but not importance, were associated with better depression outcomes. Identifying and addressing readiness for treatment by leveraging public health systems and services (e.g., help lines, family interventions) prior to or upon starting a partial hospital program may be useful to maximize gains in treatment.

RESUMO

Substance use is associated with poor outcomes for individuals with early psychosis. Community Reinforcement and Family Training (CRAFT) is an evidence-based approach that helps families to reduce substance use, engage in treatment, and improve family wellbeing, but it has not yet been studied for psychosis and substance use. The present study aimed to develop and evaluate a telehealth intervention utilizing CRAFT for families experiencing early psychosis and substance use. Twenty family members completed six to eight telehealth sessions of CRAFT adapted for early psychosis (CRAFT-EP). Participants completed an assessment battery at baseline, mid- and post-intervention, a three-month follow-up, surveys after each session, and a focus group to measure mean percentage of sessions completed, mean program satisfaction ratings, telehealth preference, and qualitative feedback. Participants had 100% session completion, and program satisfaction was at or near excellent for 99% of sessions. Half of participants preferred a primarily virtual hybrid program, whereas 45% preferred exclusively virtual visits. Communication was the most helpful topic, and participants requested additional written examples and resources. CRAFT-EP is feasible and acceptable to serve as the active intervention in a pilot randomized controlled trial comparing treatment as usual plus CRAFT-EP to treatment as usual.

RESUMO

Employers have increasingly turned to virtual interviews to facilitate online, socially distanced selection processes in the face of the COVID-19 pandemic. However, there is little understanding about the experience of job candidates in these virtual interview contexts. We draw from Event System Theory (Morgeson et al., 2015) to advance and test a conceptual model that focuses on a high-stress, high-stakes setting and integrates literatures on workplace stress with literatures on applicant reactions. We predict that when applicants ruminate about COVID-19 during an interview and have higher levels of COVID-19 exhaustion, they will have higher levels of anxiety during virtual interviews, which in turn relates to reduced interview performance, lower perceptions of fairness, and reduced intentions to recommend the organization. Further, we predict that three factors capturing COVID-19 as an enduring and impactful event (COVID-19 duration, COVID-19 cases, COVID-19 deaths) will be positively related to COVID-19 exhaustion. We tested our propositions with 8,343 job applicants across 373 companies and 93 countries/regions. Consistent with predictions, we found a positive relationship between COVID-19 rumination and interview anxiety, and this relationship was stronger for applicants who experienced higher (vs. lower) levels of COVID-19 exhaustion. In turn, interview anxiety was negatively related to interview performance, fairness perceptions, and recommendation intentions. Moreover, using a relevant subset of the data (n = 6,136), we found that COVID-19 duration and deaths were positively related to COVID-19 exhaustion. This research offers several insights for understanding the virtual interview experience embedded in the pandemic and advances the literature on applicant reactions.

RESUMO

Uncertainty is a defining feature of the COVID-19 pandemic. However, because uncertainty is an aversive state, uncertainty reduction theory (URT) holds that employees try to manage it by obtaining information. To date, most evidence for the effectiveness of obtaining information to reduce uncertainty stems from research conducted in relatively stable contexts wherein employees can acquire consistent information. Yet, research on crises and news consumption provides reasons to believe that the potential for information to mitigate uncertainty as specified by URT may break down during crises such as the COVID-19 pandemic. Integrating URT with research on crises and news consumption, we predict that consuming news information during crises-which tends to be distressing, constantly evolving, and inconsistent-will be positively related to uncertainty. This in turn may have negative implications for employee goal progress and creativity; two work outcomes that take on substantial significance in times of uncertainty and the pandemic. We further predict that death anxiety will moderate this relationship, such that the link between employees' news consumption and uncertainty is stronger for those with lower levels of death anxiety, compared to those with higher levels. We test our theorizing via an experience-sampling study with 180 full-time employees, with results providing support for our conceptual model. Our study reveals important theoretical and practical implications regarding information consumption during crises such as the COVID-19 pandemic.

RESUMO

This study expands the work-family enrichment literature by integrating enrichment theory (Greenhaus & Powell, 2006), social-cognitive theory (Bandura, 2001), capitalization theory (e.g., Gable, Reis, Impett, & Asher, 2004), and creative cognition theory (e.g., Smith, Ward, & Finke, 1995), in order to advance a novel conceptual model of the effects of resource transfer training on enrichment and job satisfaction. The model was tested by developing and evaluating a work-to-family enrichment training program, the Resource Transfer Training, which was based on Greenhaus and Powell's (2006) enrichment theory and interpersonal capitalization theory (Ilies, Keeney, & Scott, 2011). The training was administered to 163 administrative employees using a longitudinal prepost experimental design. Consistent with hypotheses, findings indicated that, compared to a control training condition, the Resource Transfer Training increased development-based enrichment from work to family (the transfer of skills, knowledge and values). Furthermore, the effect of the training on both development-based and affect-based enrichment (the transfer of positive affect) was mediated by enrichment self-efficacy, and the indirect effects of the training on enrichment were moderated by initial social-emotional work resources. Finally, as hypothesized, enrichment self-efficacy and enrichment experiences sequentially mediated the effect of the training on job satisfaction. This work advances theory by demonstrating that human agency can facilitate enrichment experiences across roles, and by exploring new antecedents of enrichment through theoretically driven training components. It advances practice by devising and testing a work-to-family enrichment intervention that can serve as a tool for organizations to increase positive synergy between work and nonwork roles.

RESUMO

The COVID-19 pandemic has unhinged the lives of employees across the globe, yet there is little understanding of how COVID-19 health anxiety (CovH anxiety)-that is, feelings of fear and apprehension about having or contracting COVID-19-impacts critical work, home, and health outcomes. In the current study, we integrate transactional stress theory (Lazarus & Folkman, 1984) with self-determination theory (Deci & Ryan, 2000) to advance and test a model predicting that CovH anxiety prompts individuals to suppress emotions, which has detrimental implications for their psychological need fulfillment. In turn, lack of psychological need fulfillment hinders employees' abilities to work effectively, engage with their family, and experience heightened well-being. Our model further predicts that handwashing frequency-a form of problem-focused coping-will mitigate the effects of CovH anxiety. We test our propositions using a longitudinal design that followed 503 employees across the first four weeks that stay-at-home and social distancing orders were enacted. Consistent with predictions, CovH anxiety was found to impair critical work (goal progress), home (family engagement) and health (somatic complaints) outcomes due to increased emotion suppression and lack of psychological need fulfillment. Further, individuals who frequently engage in handwashing behavior were buffered from the negative impact of CovH anxiety. Combined, our work integrates and extends existing theory and has a number of important practical implications. Our research represents a first step to understanding the work-, home-, and health-related implications of this unprecedented situation, highlighting the detrimental impact of the anxiety stemming from the COVID-19 pandemic.

RESUMO

BACKGROUND: Cognitive dysfunction is common in psychotic disorders, and may reflect underlying pathophysiology. However, substantial cognitive heterogeneity exists both within and between diagnostic categories, creating challenges for studying the neurobiology of cognitive dysfunction in patients. The aim of this study was to identify patients with psychosis with intact versus impaired cognitive profiles, and to examine resting state functional connectivity between patient groups and compared to healthy controls to determine the extent to which patterns of connectivity are overlapping or distinct. METHODS: Participants with affective or non-affective psychosis (n=120) and healthy controls (n=31) were administered the MATRICS Consensus Cognitive Battery, clinical and community functioning assessments, and an fMRI scan to measure resting state functional connectivity (RSFC). Cognitive composite scores were used to identify groups of patients with and without cognitive dysfunction. RSFC was compared between groups of patients and healthy controls, controlling for demographic and clinical variables. RESULTS: Both cognitively intact and cognitively impaired patients showed decreased intrinsic connectivity compared to controls in frontoparietal control (FPN) and motor networks. Patients with cognitive impairment showed additional reductions in FPN connectivity compared to patients with intact cognition, particularly in subnetwork A. CONCLUSIONS: We leveraged the heterogeneity in cognitive ability among patients with psychosis to disentangle the relative contributions of cognitive dysfunction and presence of an underlying psychotic illness using resting state functional connectivity. These findings suggest at least partially separable effects of presence of a psychotic disorder and neurocognitive impairment contributing to network dysconnectivity in psychosis.

RESUMO

BACKGROUND: Women experience greater difficulty quitting smoking than men, which may be explained by sex differences in brain circuitry underlying cognitive control. Prior work has linked reduced interhemispheric executive control network (ECN) coupling with poor executive function, shorter time to relapse, and greater substance use. Lower structural connectivity between a key ECN hub, the dorsolateral prefrontal cortex (DLPFC), and the dorsal striatum (DS) also contributes to less efficient cognitive control recruitment, and reduced intrahemispheric connectivity between these regions has been associated with smoking relapse. Therefore, sex differences were probed by evaluating interhemispheric ECN and intrahemispheric DLPFC-DS connectivity. To assess the potential sex by nicotine interaction, a pilot sample of non-smokers was evaluated following acute nicotine and placebo administration. METHODS: Thirty-five smokers (19 women) completed one resting state functional magnetic resonance imaging scan. Seventeen non-smokers (8 women) were scanned twice using a repeated measures design where they received 2 and 0 mg nicotine. RESULTS: In smokers, women had less interhemispheric ECN and DLPFC-DS coupling than men. In non-smokers, there was a drug x sex interaction where women, relative to men, had weaker ECN coupling following nicotine but not placebo administration. CONCLUSIONS: The current work indicates that nicotine-dependent women, versus men, have weaker connectivity in brain networks critically implicated in cognitive control. How these connectivity differences contribute to the behavioral aspects of smoking requires more testing. However, building on the literature, it is likely these deficits in functional connectivity contribute to the lower abstinence rates noted in women relative to men.

RESUMO

Social affiliation, or engagement in positive social interactions, is often profoundly impaired in individuals with schizophrenia. Valid measures of social affiliation are needed to understand these impairments and their symptom and functional correlates; however, such measures are limited and have not been validated. This pilot study evaluated one such measure-the video-based Social Affiliation Interaction Task (SAIT)-and a novel in vivo behavioral measure, the Affiliative Conversation Task (ACT). Twenty participants with schizophrenia or schizoaffective disorder (SZ) and 35 nonpsychiatric controls (CT) completed both tasks and measures of negative symptoms and functioning. We explored group differences in social affiliation skills; convergent validity between social affiliation skill ratings from the two tasks; and concurrent validity with social affiliation skill ratings, negative symptoms, and functioning. SZ evidenced lower affiliation skill ratings than CT on the video SAIT, but not on the ACT, and the tasks displayed moderate convergent validity for affiliation skill ratings. Less affiliation skill in the SAIT was correlated with more negative symptoms and less functioning in the SZ group with medium effects, though the results were not significant. Findings suggest that the SAIT may be more sensitive to individual differences in skill level. Future research should continue to examine the SAIT for use in measuring affiliation skills.

RESUMO

Researchers have uncovered inconsistent relations between anxiety and performance. Although the prominent view is a "dark side," where anxiety has a negative relation with performance, a "bright side" of anxiety has also been suggested. We reconcile past findings by presenting a comprehensive multilevel, multiprocess model of workplace anxiety called the theory of workplace anxiety (TWA). This model highlights the processes and conditions through which workplace anxiety may lead to debilitative and facilitative job performance and includes 19 theoretical propositions. Drawing on past theories of anxiety, resource depletion, cognitive-motivational processing, and performance, we uncover the debilitative and facilitative nature of dispositional and situational workplace anxiety by positioning emotional exhaustion, self-regulatory processing, and cognitive interference as distinct contrasting processes underlying the relationship between workplace anxiety and job performance. Extending our theoretical model, we pinpoint motivation, ability, and emotional intelligence as critical conditions that shape when workplace anxiety will debilitate and facilitate job performance. We also identify the unique employee, job, and situational characteristics that serve as antecedents of dispositional and situational workplace anxiety. The TWA offers a nuanced perspective on workplace anxiety and serves as a foundation for future work. (PsycINFO Database Record

RESUMO

Much of the earliest research on personality pathology was observational and descriptive in nature, drawing heavily on subjective self-reports, however, the last 20 years have seen a surge of interest in laboratory-based studies. Laboratory research offers a number of benefits for researchers interested in personality disorders and personality pathology including the opportunities to use objective performance-based and behavioral measures, reveal the neuropsychological and biobehavioral processes that may help shape the experience and behavior of individuals with personality disorders, and create experimental designs that allow researchers to systematically explore the effect of context on emotional, behavioral and cognitive responding. Along with these benefits, laboratory research on personality disorders has its share of methodological and interpretive challenges and raise several key questions, including (a) How should we interpret findings that diverge from theory-driven predictions? (b) How do we reconcile discrepant results from subjective and performance-based assessments? and (c) Are these discrepancies due to methodological artifact, a hallmark of the disorder, or cause for theoretical reconsideration? The goal of this article is to review studies aimed at answering a key research question in the domains of borderline personality disorder, psychopathy, and schizotypy. Our review highlights significant progress in laboratory research on personality disorders, and identifies challenges that must be addressed to capitalize on the promise of laboratory methods. It is our hope that future experimental work proceeds with an eye toward theoretical coherence, methodological rigor, ecological validity, and clinical utility. (PsycINFO Database Record

RESUMO

Negative symptoms in schizophrenia are characterized by deficits in normative experiences and expression of emotion, and they are associated with poor social functioning. Negative symptoms relating to deficits in motivation and pleasure may hinder the development of affiliative bonds. The current study used a novel procedure to examine the relation between negative symptoms and the development of social affiliation within a laboratory setting. Fifty-five men (35 controls; 20 with a schizophrenia spectrum disorder) completed three Social Affiliation Enhancement Tasks with an experimenter partner. Self-reported affiliation and affect ratings were assessed before and after the affiliative interaction. Across groups, social affiliation and positive affect increased following the interactive tasks. However, the schizophrenia group reported less positive and more negative affect than controls. Within individuals with schizophrenia, negative symptoms reflecting motivation and pleasure deficits and self-reported social anhedonia were associated with less affiliative feelings of interpersonal closeness and less willingness to interact. Additionally, these self-reported reactions to the interaction partner were significantly related to social functioning in the community. These findings indicate that though individuals with schizophrenia can form affiliative bonds, the extent to which this is possible may be limited by negative symptoms relating to motivation and pleasure. Additional research will be necessary to examine just how these negative symptoms interfere with social affiliation.

RESUMO

OBJECTIVES: Cognitive dysfunction is a core symptom dimension that cuts across the psychoses. Recent findings support classification of patients along the cognitive dimension using cluster analysis; however, data-derived groupings may be highly determined by sampling characteristics and the measures used to derive the clusters, and so their interpretability must be established. We examined cognitive clusters in a cross-diagnostic sample of patients with psychosis and associations with clinical and functional outcomes. We then compared our findings to a previous report of cognitive clusters in a separate sample using a different cognitive battery. METHODS: Participants with affective or non-affective psychosis (n=120) and healthy controls (n=31) were administered the MATRICS Consensus Cognitive Battery, and clinical and community functioning assessments. Cluster analyses were performed on cognitive variables, and clusters were compared on demographic, cognitive, and clinical measures. Results were compared to findings from our previous report. RESULTS: A four-cluster solution provided a good fit to the data; profiles included a neuropsychologically normal cluster, a globally impaired cluster, and two clusters of mixed profiles. Cognitive burden was associated with symptom severity and poorer community functioning. The patterns of cognitive performance by cluster were highly consistent with our previous findings. CONCLUSIONS: We found evidence of four cognitive subgroups of patients with psychosis, with cognitive profiles that map closely to those produced in our previous work. Clusters were associated with clinical and community variables and a measure of premorbid functioning, suggesting that they reflect meaningful groupings: replicable, and related to clinical presentation and functional outcomes.

RESUMO

BACKGROUND: Individuals who use cocaine have fewer cognitive resources needed to maintain abstinence. This is evidenced by blunted brain function during cognitive control tasks and reduced communication between brain regions associated with cognitive function. For instance, relapse vulnerability is heightened in individuals with less communication between the right and left frontoparietal executive control network (ECN). Given that recent cocaine use enhances such communication, it is plausible that recency of cocaine use influences interhemispheric ECN communication. However, it is unclear whether ECN communication weakens over the course of early cocaine abstinence, which may then enhance relapse risk. METHODS: In ten men with cocaine use disorder, we conducted a preliminary assessment of the relationship between the number of days since last cocaine use (1-3days) and interhemispheric ECN coupling using resting state functional magnetic resonance imaging (fMRI). RESULTS: Reduced interhemispheric ECN coupling was associated with increasing days since last cocaine use; weaker coupling was also associated with lower urine cocaine metabolite concentrations. This association was more prominent in prefrontal than parietal ECN-subregions. CONCLUSIONS: Preliminary results indicate that resting state interhemispheric ECN coupling weakens within the first few days following last cocaine use. Because of the known link between reduced ECN interhemispheric coupling and relapse vulnerability, these results suggest that relapse risk may increase the longer an individual abstains during an early quit attempt. Treatments focused on reversing this coupling deficit may facilitate abstinence.

RESUMO

STUDY OBJECTIVES: Insomnia is pervasive among people with serious mental illnesses (SMI) and has a profound negative impact on their psychiatric symptom management and recovery. However, little is known about the factors that affect severity of insomnia in those with SMI. In addition, very few studies have explored whether evidence-based interventions developed for those without SMI are appropriate for or applicable to individuals with SMI. The purpose of this study was to test the role of arousal, dysfunctional cognitions about sleep, and sleep-related behaviors in predicting severity of insomnia in a sample of 60 Veterans who were receiving care in Veterans Health Administration mental health and psychosocial rehabilitation programs and who reported subjective insomnia. In addition, information was collected regarding the types of insomnia treatments provided to these Veterans. METHODS: Participants completed assessments of insomnia severity and sleep-related arousal, behaviors, and cognitions. Medical records were reviewed to determine whether participants had been screened/assessed for insomnia and whether treatments for insomnia were provided before the date of referral to the study. Multiple regression was used to predict insomnia severity on the basis of these factors. RESULTS: Most participants (81.7%) reported moderate to severe insomnia, although only 3.3% had a diagnosis of insomnia in their medical records. Worry and helplessness about sleep were predictive of insomnia severity; better self-reported sleep hygiene and higher levels of arousal were also associated with greater severity of insomnia. Education about sleep hygiene and medication were the only types of insomnia treatment received. CONCLUSIONS: Similar to insomnia among individuals without SMI, insomnia in Veterans with SMI is associated with dysfunctional sleep-related behaviors and cognitions. Many of the Veterans also lacked access to settings and resources conducive to healthy sleep. Veterans with SMI should be regularly assessed for insomnia. Research is needed concerning optimal evidence-based insomnia interventions for addressing behaviors and cognitions in this population in the context of these challenges.

RESUMO

Negative symptoms like avolition and anhedonia are thought to involve difficulties with reward processing and motivation. The current study aimed to replicate and extend prior findings that individuals with schizophrenia display reduced willingness to expend effort for rewards and that such reduced effort is associated with negative symptoms, poor functioning, and cognitive impairment. The present study compared the effortful decision making of individuals with schizophrenia (n=48) and healthy controls (n=27) on the Effort Expenditure for Rewards Task (EEfRT). Individuals with schizophrenia chose a smaller proportion of hard tasks than healthy controls across all probability and reward levels with the exception of trials with a 12% probability and low or medium reward magnitude wherein both groups chose similarly few hard tasks. Contrary to expectations, in individuals with schizophrenia, greater negative symptoms were associated with making more effortful choices. Effortful decision making was unrelated to positive symptoms, depression, cognition, and functioning in individuals with schizophrenia. Our results are consistent with prior findings that revealed a pattern of inefficient decision making in individuals with schizophrenia relative to healthy controls. However the results did not support the hypothesized association of negative symptoms and reduced effort in schizophrenia and highlight prior inconsistencies in this literature. Future research is needed to understand what factors may be related to diminished effortful decision making in schizophrenia and the clinical significance of such performance deficits.

RESUMO

In this article, we draw from Conservation of Resources Theory to advance and test a framework which predicts that emotional exhaustion plays an explanatory role underlying the relation between workplace anxiety and job performance. Further, we draw from social exchange theories to predict that leader-member exchange and coworker exchange will mitigate the harmful effects of anxiety on job performance. Findings across a 3-wave study of police officers supported our model. Emotional exhaustion mediated the link between workplace anxiety and job performance, over and above the effect of cognitive interference. Further, coworker exchange mitigated the positive relation between anxiety and emotional exhaustion, while leader-member exchange mitigated the negative relation between emotional exhaustion and job performance. This study elucidates the effects of workplace anxiety on resource depletion via emotional exhaustion and highlights the value of drawing on social resources to offset the potentially harmful effects of workplace anxiety on job performance.

RESUMO

It has been proposed that anhedonia may, in part, reflect difficulties in reward processing and effortful decision making. The current study aimed to replicate previous findings of effortful decision making deficits associated with elevated anhedonia and expand upon these findings by investigating whether these decision making deficits are specific to elevated social anhedonia or are also associated with elevated positive schizotypy characteristics. The current study compared controls (n=40) to individuals elevated on social anhedonia (n=30), and individuals elevated on perceptual aberration/magical ideation (n=30) on the Effort Expenditure for Rewards Task (EEfRT). Across groups, participants chose a higher proportion of hard tasks with increasing probability of reward and reward magnitude, demonstrating sensitivity to probability and reward values. Contrary to our expectations, when the probability of reward was most uncertain (50% probability), at low and medium reward values, the social anhedonia group demonstrated more effortful decision making than either individuals high in positive schizotypy or controls. The positive schizotypy group only differed from controls (making less effortful choices than controls) when reward probability was lowest (12%) and the magnitude of reward was the smallest. Our results suggest that social anhedonia is related to intact motivation and effort for monetary rewards, but that individuals with this characteristic display a unique and perhaps inefficient pattern of effort allocation when the probability of reward is most uncertain. Future research is needed to better understand effortful decision making and the processing of reward across a range of individual difference characteristics.

RESUMO

Considerable evidence suggests that how candidates react to selection procedures can affect their test performance and their attitudes toward the hiring organization (e.g., recommending the firm to others). However, very few studies of candidate reactions have examined one of the outcomes organizations care most about: job performance. We attempt to address this gap by developing and testing a conceptual framework that delineates whether and how candidate reactions might influence job performance. We accomplish this objective using data from 4 studies (total N = 6,480), 6 selection procedures (personality tests, job knowledge tests, cognitive ability tests, work samples, situational judgment tests, and a selection inventory), 5 key candidate reactions (anxiety, motivation, belief in tests, self-efficacy, and procedural justice), 2 contexts (industry and education), 3 continents (North America, South America, and Europe), 2 study designs (predictive and concurrent), and 4 occupational areas (medical, sales, customer service, and technological). Consistent with previous research, candidate reactions were related to test scores, and test scores were related to job performance. Further, there was some evidence that reactions affected performance indirectly through their influence on test scores. Finally, in no cases did candidate reactions affect the prediction of job performance by increasing or decreasing the criterion-related validity of test scores. Implications of these findings and avenues for future research are discussed.
