Prenatal maternal Inflammation, childhood cognition and adolescent depressive symptoms.

BACKGROUND: Accumulating evidence indicates that higher prenatal maternal inflammation is associated with increased depression risk in adolescent and adult-aged offspring. Prenatal maternal inflammation (PNMI) may increase the likelihood for offspring to have lower cognitive performance, which, in turn, may heighten risk for depression onset. Therefore, this study explored the potential mediating role of childhood cognitive performance in the relationship between PNMI and adolescent depressive symptoms in offspring. METHODS: Participants included 696 mother-offspring dyads from the Child Health and Development Studies (CHDS) cohort. Biomarkers of maternal inflammation [interleukin (IL)-6, IL-8, IL-1 receptor antagonist (IL-1RA) and soluble TNF receptor-II (sTNF-RII)] were assayed from first (T1) and second trimester (T2) sera. Childhood (ages 9-11) cognitive performance was assessed via standardized Peabody Picture Vocabulary Test (PPVT), a measure of receptive vocabulary correlated with general intelligence. Adolescent (ages 15-17) depressive symptoms were assessed via self-report. RESULTS: There were no significant associations between T1 biomarkers and childhood PPVT or adolescent depressive symptoms. Higher T2 IL1-RA was directly associated with lower childhood PPVT (b = -0.21, SE = 0.08, t = -2.55, p = 0.01), but not with adolescent depressive symptoms. T2 IL-6 was not directly associated with childhood PPVT, but higher T2 IL-6 was directly associated at borderline significance with greater depressive symptoms in adolescence (b = 0.05, SE = 0.03, t = 1.96, p = 0.05). Lower childhood PPVT predicted significantly higher adolescent depressive symptoms (b = -0.07, SE = 0.02, t = -2.99, p < 0.01). There was a significant indirect effect of T2 IL-1RA on adolescent depressive symptoms via childhood PPVT (b = 0.03, 95 % CI = 0.002-0.03) indicating a partially mediated effect. No significant associations were found with T2 sTNF-RII nor IL-8. CONCLUSIONS: Lower childhood cognitive performance, such as that indicated by a lower PPVT score, represents a potential mechanism through which prenatal maternal inflammation contributes to adolescent depression risk in offspring.

Toward an Understanding of Incongruent Affect in People With Schizophrenia.

Previous studies have found that people with schizophrenia report more negative affect (NA) in response to positive and neutral stimuli (incongruent NA) than people without schizophrenia, perhaps related to heightened overall NA. We sought to decrease NA and increase positive affect (PA) using the Broad-Minded Affective Coping (BMAC) procedure in people with (n = 29) and without (n = 26) schizophrenia. We also investigated whether decreased NA would contribute to a decrease in incongruent NA in people with schizophrenia. The BMAC procedure increased PA but did not decrease NA in participants, nor did it influence reports of incongruent NA (in response to positive and neutral films) in people with schizophrenia. Baseline NA in people with schizophrenia was correlated with incongruent NA and symptom severity. Results indicate that people with schizophrenia report heightened NA that does not readily diminish in the face of heightened PA.

A multicomponent approach toward understanding emotion regulation in schizophrenia.

OBJECTIVES: Emotion deficits are well documented in people with schizophrenia. Far less is known about their ability to implement emotion regulation strategies. We sought to explore whether people with schizophrenia can modify their emotion responses similar to controls. METHODS: People with (n = 25) and without (n = 21) schizophrenia were instructed to amplify positive-emotion expression, reappraise negative emotion experience, and suppress physiological response. Multiple components of emotion response were measured (experience, expression, and physiology). RESULTS: Although people with schizophrenia showed increased positive expressivity following amplification and decreased negative emotion experience following reappraisal, overall, they expressed less positive emotion and experienced more negative emotion compared with controls. Neither group was effective at physiological suppression. CONCLUSIONS: Together these findings suggest that people with schizophrenia can engage in amplification and reappraisal when explicitly instructed to do so, albeit additional practice may be necessary to modify emotion responses to levels similar to controls.

Electrophysiological Evidence for Impaired Control of Motor Output in Schizophrenia.

Previous research has demonstrated pervasive deficits in response-related processing in people with schizophrenia (PSZ). The present study used behavioral measures and event-related potentials (ERPs) to test the hypothesis that schizophrenia involves specific impairment in the ability to exert control over response-related processing. Twenty-two PSZ and 22 matched control participants completed a choice response task in counterbalanced testing sessions that emphasized only accuracy (the unspeeded condition) or emphasized speed and accuracy equally (the speeded condition). Control participants successfully modulated behavioral and ERP indices of response-related processing under speed pressure, as evidenced by faster and less variable reaction times (RTs) and an earlier onset and increased amplitude lateralized readiness potential (LRP). By contrast, PSZ were unable to improve RT speed or variability or to modulate the LRP under speed pressure, despite showing a decrease in accuracy. Notably, response-related deficits in PSZ emerged only in the speeded condition; behavioral and ERP measures did not differ between groups in the unspeeded condition. Together, these results indicate that impairment in the ability to exert control over response-related processing may underlie response-related deficits in schizophrenia.

Spared and impaired spoken discourse processing in schizophrenia: effects of local and global language context.

Individuals with schizophrenia are impaired in a broad range of cognitive functions, including impairments in the controlled maintenance of context-relevant information. In this study, we used ERPs in human subjects to examine whether impairments in the controlled maintenance of spoken discourse context in schizophrenia lead to overreliance on local associations among the meanings of individual words. Healthy controls (n = 22) and patients (n = 22) listened to short stories in which we manipulated global discourse congruence and local priming. The target word in the last sentence of each story was globally congruent or incongruent and locally associated or unassociated. ERP local association effects did not significantly differ between control participants and schizophrenia patients. However, in contrast to controls, patients only showed effects of discourse congruence when targets were primed by a word in the local context. When patients had to use discourse context in the absence of local priming, they showed impaired brain responses to the target. Our findings indicate that schizophrenia patients are impaired during discourse comprehension when demands on controlled maintenance of context are high. We further found that ERP measures of increased reliance on local priming predicted reduced social functioning, suggesting that alterations in the neural mechanisms underlying discourse comprehension have functional consequences in the illness.

Awareness and coping with emotion in schizophrenia: acceptability, feasibility and case illustrations.

UNLABELLED: Although current treatments help to alleviate some of the symptoms of schizophrenia, people with schizophrenia often continue to experience residual symptoms. An emotion-focused treatment approach may help to improve well-being in this population by increasing positive experiences and resources. In this article, we discuss the feasibility and acceptability of a skills-based group treatment for people schizophrenia or schizoaffective disorder. As part of the Awareness and Coping with Emotion in Schizophrenia (ACES) intervention, group members learned eight empirically supported cognitive and behavioural skills covering emotional awareness and coping. Group member feedback and three case illustrations illuminate participants' experiences with the group, as well as the potential benefits and challenges of this treatment approach. These data suggest that ACES is a feasible and acceptable group intervention. Future research is needed to examine whether ACES has a selective impact on well-being, but these initial findings point to the promise of this intervention to improve quality of life for individuals with schizophrenia and schizoaffective disorder, thus filling a void in existing treatments options. KEY PRACTITIONER MESSAGE: There is a void in existing treatments for schizophrenia with few interventions focusing on increasing well-being in this population. Awareness and Coping with Emotion in Schizophrenia (ACES) is a skills-based group intervention that teaches cognitive and behavioural interventions to promote awareness and coping with emotion. Preliminary evidence demonstrates the feasibility and acceptance of the ACES group intervention in increasing well-being in those with schizophrenia. Future studies should extend this work by systematically evaluating the efficacy of this treatment approach.

Using the Beck Depression Inventory to Assess Anhedonia: A Scale Validation Study.

Anhedonia is central to several psychological disorders and a frequent target of psychosocial and pharmacological treatments. We evaluated the psychometric properties of two widely used anhedonia measures derived from the Beck Depression Inventory: a 3-item (BDI-Anh3) and a 4-item version (BDI-Anh4). We evaluated these measures in a large undergraduate sample, a community sample, and a clinical sample. Both the BDI-Anh3 and the BDI-Anh4 showed adequate internal consistency, with BDI-Anh4 performing somewhat better, across the three samples. Both measures showed good convergent and discriminant validity, even after controlling for shared variance with other items on the BDI. These findings indicate that both measures have sufficient reliability and validity to support their use by researchers and clinicians.

Daily micropractice can augment single-session interventions: A randomized controlled trial of self-compassionate touch and examining their associations with habit formation in US college students.

In this pre-registered study, we evaluated the effects of a single-session, self-guided intervention, leveraging daily micropractice (≤20 seconds/day practice) of self-compassionate touch to enhance self-compassion. We randomly assigned undergraduates (N = 135) to one of two conditions: a single-session intervention in which they were taught self-compassionate touch or a finger-tapping active control. Then, we instructed them to practice for 20 seconds/day for one month. At baseline (T1) and one-month follow-up (T2), participants completed assessments of self-compassion, growth mindset, positive affect, stress, psychopathology, habit formation, and more. In confirmatory, intention-to-treat analyses (N = 135), we found no significant effects on these outcomes. However, in confirmatory, per-protocol analyses (comparing the subsets from each condition who practiced>28 times, N = 45), self-compassionate touch, relative to active control, predicted T1-to-T2 increases in self-compassion (ß = 0.71, p = .025), and reductions in stress (ß = -0.62, p = .047) and psychopathology (ß = -0.61, p = .046). In exploratory intention-to-treat analyses (N = 135), we found the same pattern of effects as in the per-protocol analyses among those who practiced self-compassionate touch more frequently relative to active control. We discuss factors associated with habit formation of daily practice. Daily micropractices have the potential for augmenting single-session interventions and for offering help when more time-intensive approaches may be less accessible. CLINICAL TRIAL REGISTRATION NUMBER: NCT05199779.

Emotion deficits in people with schizophrenia.

Translational research on emotion in schizophrenia has revealed deficits in emotion perception and expression, as well as intact areas, including emotional experience and brain activation in the presence of emotionally evocative material. Yet, a closer look at emotional experience reveals that all is not well in the experience domain. People with schizophrenia have difficulty anticipating emotional events and maintaining or savoring their emotional experiences, as evidenced in behavioral, psychophysiological, and brain imaging studies. Furthermore, people with schizophrenia have difficulty integrating emotion perception with context and reporting on feelings that are differently valenced than presented emotional stimuli. Differences in brain activation are typically observed in areas tightly coupled with cognitive control, such as the dorsolateral prefrontal cortex, and thus the latest research on emotion in schizophrenia explicitly integrates emotion and cognition. Translational research holds promise to identify when in the course of the disorder emotion deficits emerge and to develop more effective interventions for schizophrenia.

Who do you trust? The impact of facial emotion and behaviour on decision making.

During social interactions, we use available information to guide our decisions, including behaviour and emotional displays. In some situations, behaviour and emotional displays may be incongruent, complicating decision making. This study had two main aims: first, to investigate the independent contributions of behaviour and facial displays of emotion on decisions to trust, and, second, to examine what happens when the information being signalled by a facial display is incongruent with behaviour. Participants played a modified version of the Trust Game in which they learned simulated players' behaviour with or without concurrent displays of facial emotion. Results indicated that displays of anger, but not happiness, influenced decisions to trust during initial encounters. Over the course of repeated interactions, however, emotional displays consistent with an established pattern of behaviour made independent contributions to decision making, strengthening decisions to trust. When facial display and behaviour were incongruent, participants used current behaviour to inform decision making.

Emotional responding in depression: distinctions in the time course of emotion.

The current studies were designed to investigate if the emotion context insensitivity hypothesis (ECI; Rottenberg & Gotlib, 2004) is applicable across the time course of emotion. Recent affective science research has pointed to the importance of considering anticipation and maintenance of emotion. In the current studies, we assessed emotion responses among college students with depression symptoms in anticipation of, during, and after an emotional picture using the emotion modulated startle paradigm. People with and without depression symptoms did not differ in blink magnitude in anticipation of emotional pictures suggesting that some anticipatory processes may not be impaired by depression symptoms. In contrast, individuals with depression symptoms did not exhibit blink magnitudes that varied by valence, either during viewing or after the pictures were removed from view. These findings suggest that ECI is relevant not only for those diagnosed with major depressive disorder, but also for people with depression symptoms that may not cross the diagnostic threshold. These data also point to the importance of considering the time course of emotion to better understand emotional deficits in individuals with differing levels of depression symptoms. Identifying where emotion goes awry across the time course of emotion can help inform treatment development.

What gets in the way of social engagement in schizophrenia?

BACKGROUND: Social engagement-important for health and well-being-can be difficult for people with schizophrenia. Past research indicates that despite expressing interest in social interactions, people with schizophrenia report spending less time with others and feeling lonely. Social motivations and barriers may play an important role for understanding social engagement in schizophrenia. AIM: To investigate how people with schizophrenia describe factors that impede and promote social engagement. METHODS: We interviewed a community sample of people with (n = 35) and without (n = 27) schizophrenia or schizoaffective disorder about their social interactions with friends and family over the past week and planned social activities for the coming week. We reviewed the interview transcripts and developed a novel coding system to capture whether interactions occurred, who had initiated the contact, and frequency of reported social barriers (i.e., internal, conflict-based, logistical) and social motivations (i.e., instrumental, affiliative, obligation-based). We also assessed symptoms and functioning. RESULTS: People with schizophrenia were less likely than people without schizophrenia to have spent time with friends [t (51.04) = 2.09, P = 0.042, d = 0.51)], but not family. People with schizophrenia reported more social barriers than people without schizophrenia [F (1, 60) = 10.55, P = 0.002, ηp2 = 0.15)] but did not differ in reported social motivations. Specifically, people with schizophrenia reported more internal [t (45.75) = 3.40, P = 0.001, d = 0.83)] and conflict-based [t (40.11) = 3.03, P = 0.004, d = 0.73)] barriers than people without schizophrenia. Social barriers and motivations were related to real-world social functioning for people with schizophrenia, such that more barriers were associated with more difficulty in close relationships (r = -0.37, P = 0.027) and more motivations were associated with better community functioning (r = 0.38, P = 0.024). CONCLUSION: These findings highlight the importance of assessing first person accounts of social barriers and motivations to better understand social engagement in schizophrenia.

The Future of Women in Psychological Science.

There has been extensive discussion about gender gaps in representation and career advancement in the sciences. However, psychological science itself has yet to be the focus of discussion or systematic review, despite our field's investment in questions of equity, status, well-being, gender bias, and gender disparities. In the present article, we consider 10 topics relevant for women's career advancement in psychological science. We focus on issues that have been the subject of empirical study, discuss relevant evidence within and outside of psychological science, and draw on established psychological theory and social-science research to begin to chart a path forward. We hope that better understanding of these issues within the field will shed light on areas of existing gender gaps in the discipline and areas where positive change has happened, and spark conversation within our field about how to create lasting change to mitigate remaining gender differences in psychological science.

Anticipatory and consummatory components of the experience of pleasure in schizophrenia: cross-cultural validation and extension.

This study examined anticipatory and consummatory pleasure in schizophrenia patients with and without negative symptoms. Negative symptom patients experienced less anticipatory pleasure than non-negative symptom patients; only one facet of consummatory pleasure was unaffected in negative schizophrenia. Greater pleasure deficits were correlated with more severe positive and negative symptoms.

Loving-kindness meditation to enhance recovery from negative symptoms of schizophrenia.

In this article, we describe the clinical applicability of loving-kindness meditation (LKM) to individuals suffering from schizophrenia-spectrum disorders with persistent negative symptoms. LKM may have potential for reducing negative symptoms such as anhedonia, avolition, and asociality while enhancing factors consistent with psychological recovery such as hope and purpose in life. Case studies will illustrate how to conduct this group treatment with clients with negative symptoms, the potential benefits to the client, and difficulties that may arise. Although LKM requires further empirical support, it promises to be an important intervention since there are few treatments for clients afflicted with negative symptoms.

Emotion regulation strategy use and eating disorder symptoms in daily life.

OBJECTIVE: Emotion regulation is posited to be disrupted in eating disorders, but studies have yet to examine the linkage between eating disorder symptoms and emotion regulation strategy use in daily life. We conducted an experience sampling study investigating associations between trait-level difficulties with emotion regulation, daily emotion regulation strategy use, and eating disorder symptoms in daily life. METHOD: Fifty-three undergraduate women completed a trait-level measure of difficulties with emotion regulation, then reported their use of emotion regulation strategies four times per day for seven days. At the end of each day, they also reported daily disordered eating symptoms and behaviors. RESULTS: Reduced access to emotion regulation strategies at the trait-level was associated with dimensional eating disorder symptoms and food restriction across the study period. In addition, greater use of maladaptive strategies and attentional deployment and less use of adaptive strategies on a given day were associated with a higher likelihood of food restriction on that day. Moderation analyses based on baseline eating disorder symptoms indicated that associations were consistent across symptom severity. CONCLUSIONS: These findings suggest that certain eating disorder symptoms are associated with difficulties in regulating emotions at the trait-level and in daily life.

Defeatist performance beliefs in college students: Transdiagnostic associations with symptoms and daily goal-directed behavior.

Defeatist performance beliefs are prevalent and linked to decreased motivation in people with psychological disorders. In this study, we investigated whether defeatist performance beliefs were associated with transdiagnostic psychopathology risk in people with no history of formal diagnosis and whether defeatist performance beliefs impacted engagement in daily goal-directed behavior. One hundred and two college students completed self-report measures of defeatist performance beliefs and risk for depression, mania, and psychosis. Sixty-one of these participants were randomly selected to identify a goal and complete daily surveys about their actual and expected goal progress, effort expenditure, experienced pleasure, and difficulty of goal pursuit. We found that greater defeatist performance beliefs were associated with higher risk for depression, mania, and psychosis. Using multilevel modeling, we found that greater defeatist performance beliefs predicted less goal progress, effort expenditure, and pleasure from goal pursuit. Together, these findings suggest that defeatist performance beliefs may impact goal-directed behavior in healthy people with no reported psychiatric history. Interventions targeting defeatist performance beliefs may have utility for actual goal-directed behavior in many people, regardless of psychiatric status.

A positive emotion regulation intervention for bipolar I disorder: Treatment development and initial outcomes.

OBJECTIVE: Dysfunction in positive affect is a defining symptom of bipolar I disorder (BD), both during and between mood episodes. We hypothesize that helping people with BD learn skills to create balance in their affective experiences by engaging in strategies that increase low activation positive emotion (LAP; e.g., relaxation) could help to improve well-being during periods of symptom remission. We discuss the development and preliminary outcomes of a positive emotion regulation (PER) group treatment for people with BD, designed as a supplement to pharmacological treatment. METHOD: The Learning Affective Understanding for a Rich Emotional Life (LAUREL) intervention is a group-based intervention covering 10 empirically supported skills designed to increase LAP. Sixteen people with BD enrolled in the LAUREL intervention and twelve completed baseline and post-intervention assessments. RESULTS: Participants who completed the study (n = 12) attended the majority of groups (87.96%) and reported practicing skills, on average, 16 times a week. We were unable to detect significant differences in mania symptoms following engagement in this PER intervention. Finally, participants reported increases in several areas associated with well-being post-intervention, including mindfulness, reappraisal, and self-compassion. CONCLUSION: This study provides a theoretical framework and preliminary support for a PER intervention for BD.

Emotional response deficits in schizophrenia: insights from affective science.

Our understanding of the emotional features of schizophrenia has benefited greatly from the adoption of methods and theory from the field of affective science. This article covers basic concepts and methods from affective science on the psychological and neural mechanisms contributing to emotions and reviews the ways in which this research has advanced our understanding of emotional response deficits in schizophrenia. We review naturalistic studies and elicitation studies that evoke emotion responses among participants, including emotion expression, experience, and autonomic physiology. We also consider how these emotion response measures correspond to schizophrenia symptoms, and we focus particular attention on the issue of sex differences in emotional responding and how this may influence our understanding emotional functioning among individuals with schizophrenia.

Social cognition in schizophrenia: an NIMH workshop on definitions, assessment, and research opportunities.

Social cognition has become a high priority area for the study of schizophrenia. However, despite developments in this area, progress remains limited by inconsistent terminology and differences in the way social cognition is measured. To address these obstacles, a consensus-building meeting on social cognition in schizophrenia was held at the National Institute of Mental Health in March 2006. Agreement was reached on several points, including definitions of terms, the significance of social cognition for schizophrenia research, and suggestions for future research directions. The importance of translational interdisciplinary research teams was emphasized. The current article presents a summary of these discussions.
