The death of a loved one can trigger a range of emotional, behavioral, motivational and cognitive reactions collectively labeled as "grief." There has been a recent resurgence of empirical interest in grief reactions, and there is now a general consensus that 7%-10% of bereaved individuals experience intense and chronic reactions termed Prolonged Grief (PG). However, there is ongoing debate about how best to conceptualize the construct. Recent studies have advanced this debate by applying a network, or causal systems approach...

Insomnia is robustly associated with suicidal behavior, but methodological limitations in existing studies hinder nuanced understanding of this relationship. The current study addressed these limitations by utilizing a longitudinal design and advanced statistical modeling. Participants who endorsed lifetime experience of suicidal behavior were recruited through Amazon's Mechanical Turk (N = 589) and completed self-report online surveys at 6 time points over a 15-day period. Latent difference score modeling was utilized to investigate whether levels and/or changes in insomnia symptoms drive subsequent changes in suicide ideation, or vice versa...

There is considerable variation in negative and positive symptoms of psychosis, global functioning, and emotional face perception (EFP), not only in schizophrenia but also in other psychotic disorders and healthy individuals. However, EFP impairment and its association with worse symptoms and global functioning have been examined largely in the domain of schizophrenia. The present study adopted a dimensional approach to examine the association of behavioral and neural measures of EFP with symptoms of psychosis and global functioning across individuals with schizophrenia spectrum (SZ; N = 28) and other psychotic (OP; N = 29) disorders, and never-psychotic participants (NP; N = 21)...

Structural learning is fundamental to the formation of cognitive maps that are necessary for learning, memory, and spatial navigation. It also enables successful navigation of the social world, which is something that individuals with autism spectrum disorder (ASD) find particularly difficult. To master these situations, a person needs to bind pieces of information to one another and to consider the context in which experiences happen. Such binding is a capacity of the hippocampus. Although altered hippocampal function has for long been suspected to play a role in the etiology of ASD, the relevant evidence has remained inconclusive because few behavioral tests that are known to specifically necessitate preserved hippocampal function have been employed in studies of ASD...

Frontal electroencephalographic alpha asymmetry as an indicator of trait approach and trait inhibition systems has previously been studied in individuals with obsessive-compulsive disorder (OCD) with mixed results. We explored frontal alpha asymmetry as a possible risk factor in OCD by investigating a large sample of OCD patients (n = 113), healthy control participants (n = 113), and unaffected 1st-degree relatives of OCD patients (n = 37). Additionally, the relationship between OCD symptom dimensions and frontal alpha asymmetry was explored...

Alcohol use disorder (AUD) and major depressive disorder (MDD) are often comorbid. It is not understood how genetic risk factors for these disorders relate to each other over time and to what degree they are stable. Age-dependent characteristics of the disorders indicate that different genetic factors could be relevant at different stages of life, and MDD may become increasingly correlated with AUD over time. DSM-IV diagnoses of AUD and MDD were assessed by interviews of 2,801 young adult twins between 1999 and 2004 (T1) and 2,284 of the same twins between 2010 and 2011 (T2)...

Reports an error in "Neural reactivity to rewards and losses in offspring of mothers and fathers with histories of depressive and anxiety disorders" by Autumn Kujawa, Greg Hajcak Proudfit and Daniel N. Klein (Journal of Abnormal Psychology, 2014[May], Vol 123[2], 287-297). In the original article, there was an error in the Measures section. The article stated that the EEG data were band-pass filtered with cutoffs of 0.1 and 30 Hz and baseline corrected using the 200 ms interval prior to feedback. Instead, the data were actually filtered with cutoffs of 0...

Two studies examined 2 important but previously unanswered questions about the experience of suicidal ideation: (a) How does suicidal ideation vary over short periods of time?, and (b) To what degree do risk factors for suicidal ideation vary over short periods and are such changes associated with changes in suicidal ideation? Participants in Study 1 were 54 adults who had attempted suicide in the previous year and completed 28 days of ecological momentary assessment (EMA; average of 2.51 assessments per day; 2,891 unique assessments)...

Classification of emotional disorders faces challenges of within-disorder heterogeneity and between-disorder comorbidity. The current study addressed these issues by analyzing all emotional disorder symptoms to identify homogeneous dimensions that characterize this domain. These dimensions were, in turn, used to define coherent syndromes and higher order factors. All of the emotional disorder symptoms specified in diagnostic manuals were assessed by interview in 2 treatment-seeking samples (N = 426 and 305), alongside clinical diagnoses and functioning measures...

The present study was designed to test the hypothesis that anorexia nervosa (AN) patients are relatively insensitive to the attentional capture of visual food stimuli. Attentional avoidance of food might help AN patients to prevent more elaborate processing of food stimuli and the subsequent generation of craving, which might enable AN patients to maintain their strict diet. Participants were 66 restrictive AN spectrum patients and 55 healthy controls. A single-target rapid serial visual presentation task was used with food and disorder-neutral cues as critical distracter stimuli and disorder-neutral pictures as target stimuli...

In the clinical neuroscience literature, between-subjects differences in neural activity are presumed to reflect reliable measures-even though the psychometric properties of neural measures are almost never reported. The current article focuses on the critical importance of assessing and reporting internal consistency reliability-the homogeneity of "items" that comprise a neural "score." We demonstrate how variability in the internal consistency of neural measures limits between-subjects (i.e., individual differences) effects...

The longitudinal structure of depression in children and adolescents was examined by applying a Trait-State-Occasion structural equation model to 4 waves of self, teacher, peer, and parent reports in 2 age groups (9 to 13 and 13 to 16 years old). Analyses revealed that the depression latent variable consisted of 2 longitudinal factors: a time-invariant dimension that was completely stable over time and a time-varying dimension that was not perfectly stable over time. Different sources of information were differentially sensitive to these 2 dimensions...

Avoidance is regarded as an important feature for the development and maintenance of obsessive-compulsive disorder (OCD) and is usually assessed using explicit measures such as self-report scales. However, some behavioral schemata are unavailable to introspection, making them partially inaccessible by explicit measures. We used an approach-avoidance task (AAT) as an implicit measure to examine behavioral tendencies in patients with OCD, including patients with checking- and contamination-related symptoms (n = 63), compared with a healthy control group (n = 30)...

Motivational and hedonic impairments are core features of a variety of types of psychopathology. An important aspect of motivational function is reinforcement learning (RL), including implicit (i.e., outside of conscious awareness) and explicit (i.e., including explicit representations about potential reward associations) learning, as well as both positive reinforcement (learning about actions that lead to reward) and punishment (learning to avoid actions that lead to loss). Here we present data from paradigms designed to assess both positive and negative components of both implicit and explicit RL, examine performance on each of these tasks among individuals with schizophrenia, schizoaffective disorder, and bipolar disorder with psychosis, and examine their relative relationships to specific symptom domains transdiagnostically...

Explicit instructions regarding stimulus-threat associations increase acquisition and extinction of fear in healthy participants. The current study aimed to investigate the effect of contingency instructions on fear acquisition and extinction in patients with anxiety disorders. Patients with various anxiety disorders (N = 104) and healthy comparison participants (N = 93) participated in a differential fear conditioning task (within-subjects design). Approximately halfway through the acquisition phase, participants were instructed about the stimulus-threat association, and approximately halfway through the extinction phase, participants were informed that the unconditioned stimulus (US) would no longer be administered...

Stress plays a key role in addiction etiology and relapse. Rodent models posit that following repeated periods of alcohol and other drug intoxication, compensatory allostatic changes occur in the central nervous system (CNS) circuits involved in behavioral and emotional response to stressors. We examine a predicted manifestation of this neuroadaptation in recently abstinent alcohol-dependent humans. Participants completed a translational laboratory task that uses startle potentiation to unpredictable (vs. predictable) stressors implicated in the putative CNS mechanisms that mediate this neuroadaptation...

Theoretical and empirical work suggests that aggression in those with borderline personality disorder (BPD) occurs primarily in the context of emotional reactivity, especially anger and shame, in response to perceived rejection. Using intensive repeated measures, we examined a within-person process model in which perceived rejection predicts increases in aggressive urges and behaviors via increases in negative affect (indirect effect) and in which BPD symptoms exacerbate this process (moderated mediation). Participants were 117 emerging adult women (ages 18-24) with recent histories of aggressive behavior who were recruited from a community-based longitudinal study of at-risk youth...

The Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM-5) proposes an alternative model for personality disorders, which includes maladaptive-level personality traits. These traits can be operationalized by the Personality Inventory for the DSM-5 (PID-5). Although there has been extensive research on genetic and environmental influences on normative level personality, the heritability of the DSM-5 traits remains understudied. The present study addresses this gap in the literature by assessing traits indexed by the PID-5 and the International Personality Item Pool NEO (IPIP-NEO) in adult twins (N = 1,812 individuals)...

Individuals with schizophrenia display notable deficits in social functioning. Research indicates that neural connectivity within the default mode network (DMN) is related to social cognition and social functioning in healthy and clinical populations. However, the association between DMN connectivity, social cognition, and social functioning has not been studied in schizophrenia. For the present study, the authors used resting-state neuroimaging data to evaluate connectivity between the main DMN hubs (i.e., the medial prefrontal cortex [mPFC] and the posterior cingulate cortex-anterior precuneus [PPC]) in individuals with schizophrenia (n = 28) and controls (n = 32)...
