Is processing speed a valid neurocognitive endophenotype in bipolar disorder? Evidence from a longitudinal, family study. J Psychiatr Res 2021; 141:241-247. [PMID: 34256275 DOI: 10.1016/j.jpsychires.2021.07.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 06/30/2021] [Accepted: 07/05/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Substantial evidence supports the existence of neurocognitive endophenotypes in bipolar disorder (BD), but very few longitudinal studies have included unaffected relatives. In a 5-year, follow-up, family study, we have recently suggested that deficits in manual motor speed and visual memory could be endophenotype candidates for BD. We aimed to explore whether this also applies to processing speed. METHODS A sample of 348 individuals, including 163 BD patients, 65 unaffected first-degree relatives (BD-Rel) and 120 genetically unrelated healthy controls (HC), was assessed with the Digit Symbol Substitution Test (DSST) on two occasions over a 2-year period (T1, T2). DSST values were controlled for age, years of education, occupational status, and subsyndromic mood symptoms. Differences between groups were evaluated with ANCOVAs. RESULTS At T1 BD performed significantly worse than HC (p < 0.001; Cohen's d = 1.38) and BD-Rel (p < 0.001; Cohen's d = 0.82). BD-Rel showed an intermediate performance with significant differences with HC (p < 0.01; Cohen's d = 0.50). Similarly, at T2 BD performed significantly worse than HC (p < 0.001; Cohen's d = 1.44) and BD-Rel (p < 0.01; Cohen's d = 0.51). BD-Rel performance was intermediate and significantly lower than that of HC (p < 0.01; Cohen's d = 0.97). A Repeated Measures ANOVA revealed no significant between-group differences in performance over time (p > 0.05). CONCLUSIONS The results of this longitudinal, family study suggest that impaired processing speed may represent a suitable cognitive endophenotype for BD. Further research on the field is required to confirm these preliminary findings.

Abstract
OBJECTIVE The main aims of this study were to examine the differences in the Emotional Intelligence (EI), the emotional domain of social cognition (SC), between euthymic patients with bipolar disorder (BD) and healthy controls (HC) and to evaluate the contribution of sociodemographic, clinical, and neuropsychological variables to EI. METHODS We recruited 202 patients with BD and 50 HC. EI was evaluated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). The sociodemographic, clinical, and neurocognitive variables that showed a significant association with EI were entered into hierarchical multiple regression analysis. RESULTS BD patients obtained significantly lower scores compared to HC in the Emotional Intelligence Quotient (EIQ) and in the Understanding Emotions branch score. The best fitting model for the variables associated with EI in the patients group was a linear combination of gender, estimated IQ, family history of affective diagnosis, and executive function. The model, including these previous variables, explained up to 27.6% of the observed variance (R2 = 0.276, F = 16.406, P < 0.001). CONCLUSIONS The identification of variables associated with deficit in EI, such as male gender, lower estimated IQ, family history of affective diagnosis. and lower executive function performance, may help in selecting treatment targets to improve SC, and especially EI, in patients with BD.

The association between social skills deficits and family history of mood disorder in bipolar I disorder. BRAZILIAN JOURNAL OF PSYCHIATRY 2018; 40:244-248. [PMID: 29590265 PMCID: PMC6899394 DOI: 10.1590/1516-4446-2017-2313] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/23/2017] [Accepted: 07/28/2017] [Indexed: 11/21/2022]
Abstract
Objective: To compare social skills and related executive functions among bipolar disorder (BD) patients with a family history of mood disorders (FHMD), BD patients with no FHMD and healthy control (HCs). Methods: We evaluated 20 euthymic patients with FHMD, 17 euthymic patients without FHMD, and 31 HCs using the Social Skills Inventory (SSI) and a neuropsychological battery evaluating executive function, inhibitory control, verbal fluency and estimated intelligence. Results: Both BD groups had lower SSI scores than controls. Scores for one subfactor of the social skills questionnaire, conversational skills and social performance, were significantly lower among patients with FHMD than among patients without FHMD (p = 0.019). Both groups of BD patients exhibited significant deficits in initiation/inhibition, but only BD patients with FHMD had deficits in verbal fluency, both compared to HC. There were no associations between social skills questionnaire scores and measures of cognitive function. Conclusion: Euthymic BD patients have lower social skills and executive function performance than HC. The presence of FHMD among BD patients is specifically associated with deficits in conversational and social performance skills, in addition to deficits in verbal fluency. Both characteristics might be associated with a common genetically determined pathophysiological substrate.

Abstract
BACKGROUND Highly hypnotizable individuals have impaired executive function, elevated motor impulsivity and increased emotional sensitivity, which are sometimes found in bipolar disorder patients. It is then reasonable to assume that certain aspects of hypnotic susceptibility differ with the types of bipolar disorder. METHODS The Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) test, the Mood Disorder Questionnaire (MDQ), the Hypomanic Checklist-32 (HCL-32) and the Plutchick-van Praag Depression Inventory (PVP) were applied to 62 patients with bipolar I disorder, 33 bipolar II disorder, and 120 healthy volunteers. RESULTS The passing rate of the SHSS:C 'Moving hands apart' item was higher in bipolar I patients than in controls, whereas for 'Mosquito hallucination' the rate was lower. Bipolar I and II patients scored significantly higher on MDQ, HCL-32 and PVP scales than controls. The passing rates of 'Mosquito hallucination' in controls, 'Arm rigidity' in bipolar I, and 'Age regression' in bipolar II predicted the respective MDQ scores. CONCLUSION In contrast to cognitive suggestions, bipolar I patients followed motor suggestions more often under hypnosis. Furthermore, both bipolar disorder patients and healthy volunteers demonstrated associations between mania levels and certain hypnotic susceptibility features. Our study aids in better understanding the altered conscious states in bipolar disorders, and encourages the use of related psychotherapy for these patients.

Abstract
OBJECTIVES Patients with bipolar disorder often suffer from cognitive impairment that significantly influences their functional outcome. However, it remains unknown whether lithium has a central role in cognition and functional outcome. We examined whether cognition and functional outcome were predicted by demographic and clinical variables, including the response to lithium, in lithium-treated patients with bipolar disorder. METHODS We evaluated 96 lithium-treated euthymic patients with bipolar disorder and 196 age- and-gender-matched healthy controls, using the Brief Assessment of Cognition in Schizophrenia (BACS). The patients were also assessed using the Social Functioning Scale (SFS) and "The Retrospective Criteria of Long-Term Treatment Response in Research Subjects with Bipolar Disorder" (Alda) scale, which was evaluated as either a continuous measure of the total scale or a dichotomous criterion. RESULTS Multiple regression analysis revealed two key findings: first, that the premorbid intelligence quotient, age, and number of mood episodes were predictors of the BACS composite score; and, second, that the BACS composite score, negative symptoms, and continuous measure on the total Alda scale (but not its dichotomy) predicted the total SFS score. Structural equation modeling (SEM) was used to confirm these findings, and additionally revealed that the Alda scale was significantly associated with negative symptoms and also the number of mood episodes, regardless of how it was evaluated. CONCLUSIONS SEM delineated how demographic and clinical variables, cognitive performance, and response to lithium treatment were causally associated with, and converged on, social function. The putative role of the Alda scale for social function warrants further study.

Abstract
Little is known about the development of cognitive deficits prior to the official onset of bipolar disorder (BP). The aim of this study was to investigate neurocognitive performance in two early stages of BP. This high-risk design study recruited a group of offspring of parents with BP (n = 58), aged 8-28 years. Based on the subthreshold syndromes, the "unaffected" offspring were further divided into high-risk (HR) and ultra-high-risk (UHR) stages. For comparison, a group of individuals with subthreshold symptoms but without family history of psychiatric disorder (n = 17) and 48 healthy controls (HCs) were included. The MATRICS Consensus Cognitive Battery (MCCB) and Tower of London task were applied to assess neuropsychological performance. The HR offspring performed significantly poorer on verbal learning and memory when compared with HCs, indicating that the deficits may serve as neurocognitive endophenotypes for BP. Deficits in working memory, visual-spatial memory, and cognitive planning were observed in the UHR offspring when compared with HCs, suggestive of risk of developing BP. The deficits observed in the UHR offspring were absent in the individuals with subthreshold symptoms without psychiatric family history. Our data suggest that cognitive deficits become apparent prior to the official onset of BP, with specific deficits observable in different early stages. These results nonetheless are based on small sample size and a cross-sectional design. Given this and the heterogeneity of bipolar disorders, these findings should be interpreted cautiously and require replication.

Abstract
INTRODUCTION Although cognitive deficits are consistent endophenotypes of schizophrenia and bipolar disorder, findings in psychotic bipolar disorder (BDP) are inconsistent. In this study we compared adult unaffected first-degree relatives of schizophrenia and BDP patients on cognition, psychopathology, social functioning and quality of life. METHODS Sixty-six unaffected first-degree relatives of schizophrenia patients (SUnR), 36 unaffected first-degree relatives of BDP patients (BDPUnR) and 102 controls participated in the study. Between-group differences were examined and Discriminant Function Analysis (DFA) predicted group membership. RESULTS Visual memory, control inhibition, working memory, cognitive flexibility and abstract reasoning were linearly impaired in the relatives' groups. Poorer verbal fluency and processing speed were evident only in the SUnR group. The SUnR group had higher depressive and somatization symptoms while the BDPUnR group had higher anxiety and lower social functioning compared with the controls. Individuals with superior cognition were more likely to be classified as controls; those with higher social functioning, prolonged processing speed and lower anxiety were more likely to be classified as SUnR. LIMITATIONS The relatives' sample is quite heterogeneous; the effects of genetic or environmental risk-factors were not examined. CONCLUSIONS Cognitive functions mediated by a fronto-parietal network, show linear impairments in unaffected relatives of BDP and schizophrenia patients; processing speed and verbal fluency impairments were evident only in schizophrenia relatives. Self-perceived symptomatology and social functioning also differ between schizophrenia and BDP relatives. The continuum seen in patients in several indices was also seen in the cognitive impairments in unaffected relatives of schizophrenia and BDP patients.

Abstract
BACKGROUND Neurocognitive deficits are present in bipolar disorder (BD) patients and their unaffected (nonbipolar) relatives, but it is not clear which domains are most often impaired and the extent of the impairment resulting from shared genetic factors. In this literature review, we address these issues and identify specific neurocognitive tasks most sensitive to cognitive deficits in patients and unaffected relatives. METHOD We conducted a systematic review in Web of Science, PubMed/Medline and PsycINFO databases. RESULTS Fifty-one articles assessing cognitive functioning in BD patients (23 studies) and unaffected relatives (28 studies) were examined. Patients and, less so, relatives show impairments in attention, processing speed, verbal learning/memory, and verbal fluency. CONCLUSION Studies were more likely to find impairment in patients than relatives, suggesting that some neurocognitive deficits may be a result of the illness itself and/or its treatment. However, small sample sizes, differences among relatives studied (e.g., relatedness, diagnostic status, age), and differences in assessment instruments may contribute to inconsistencies in reported neurocognitive performance among relatives. Additional studies addressing these issues are needed.

Abstract
OBJECTIVE Studies investigating the cognitive function of healthy relatives of patients with bipolar disorder are conflicting, and the neurocognitive profile of relatives of bipolar disorder probands is still unclear. We aimed to evaluate executive function in unaffected parents of familial and sporadic patients with bipolar disorder. METHODS The study included 24 unaffected familial parents (FP) of patients with bipolar disorder, 26 unaffected sporadic parents (SP) of patients with bipolar disorder and 26 controls matched with the parents for gender, age and duration of education (76 subjects in total). All of the subjects were interviewed with the Structured Clinical Interview for DSM-IV-Axis I. Executive function was assessed using the California Verbal Learning Test (CVLT), the Trail Making Test (TMT), the Wisconsin Card Sorting Test (WCST) and the Stroop test. RESULTS In comparison to their respective matched controls, FP performed significantly worse on the CVLT, TMT, WCST and Stroop test, whereas SP performed significantly worse only on WCST perseverative errors and Stroop color test. FP performed significantly worse than SP on the CVLT, TMT, and WCST. CONCLUSION The present study investigated relatives with and without a family history of bipolar disorder separately and found that executive function was impaired in parents with a positive family history of bipolar disorder. These findings bring more evidence suggesting that deficits in prefrontal executive function and verbal memory are associated with familial vulnerability to bipolar disorder and that executive function and verbal memory impairments may represent a potential endophenotype of bipolar disorder.

Tsitsipa E, Fountoulakis KN. The neurocognitive functioning in bipolar disorder: a systematic review of data. Ann Gen Psychiatry 2015; 14:42. [PMID: 26628905 PMCID: PMC4666163 DOI: 10.1186/s12991-015-0081-z] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2015] [Accepted: 11/18/2015] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND During the last decades, there have been many different opinions concerning the neurocognitive function in Bipolar disorder (BD). The aim of the current study was to perform a systematic review of the literature and to synthesize the data in a comprehensive picture of the neurocognitive dysfunction in BD. METHODS Papers were located with searches in PubMed/MEDLINE, through June 1st 2015. The review followed a modified version of the recommendations of the Preferred Items for Reporting of Systematic Reviews and Meta-Analyses statement. RESULTS The initial search returned 110,403 papers. After the deletion of duplicates, 11,771 papers remained for further evaluation. Eventually, 250 were included in the analysis. CONCLUSION The current review supports the presence of a neurocognitive deficit in BD, in almost all neurocognitive domains. This deficit is qualitative similar to that observed in schizophrenia but it is less severe. There are no differences between BD subtypes. Its origin is unclear. It seems it is an enduring component and represents a core primary characteristic of the illness, rather than being secondary to the mood state or medication. This core deficit is confounded (either increased or attenuated) by the disease phase, specific personal characteristics of the patients (age, gender, education, etc.), current symptomatology and its treatment (especially psychotic features) and long-term course and long-term exposure to medication, psychiatric and somatic comorbidity and alcohol and/or substance abuse.

Verbal memory as a mediator in the relationship between subthreshold depressive symptoms and functional outcome in bipolar disorder. J Affect Disord 2014; 160:50-4. [PMID: 24709022 DOI: 10.1016/j.jad.2014.02.034] [Citation(s) in RCA: 56] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Revised: 02/24/2014] [Accepted: 02/26/2014] [Indexed: 11/30/2022]
Abstract
BACKGROUND Most studies on the factors involved in the functional outcome of patients with bipolar disorder have identified subsyndromal depressive symptoms and cognitive impairment as key players. However, most studies are cross-sectional and very few have analyzed the interaction between cognition and subclinical depression. The present study aimed to identify the role of cognition, and particularly verbal memory, and subthreshold depressive symptoms in the functional outcome of patients with bipolar I and II disorder at one year follow-up. METHOD A confirmatory analysis was performed using the path analysis. A total of 111 euthymic patients were included to test the role of verbal memory as a mediator in the relationship of subthreshold depressive symptoms and functional outcome at one year follow-up. Measures of verbal memory, subthreshold depressive symptoms and functioning (at baseline, at 6 months and at one year follow-up) were gathered through the use of a neuropsychological assessment and validated clinical scales. RESULTS The hypothesized mediation model displayed a good fit to data (Chi=0.393, df=2, p=0.625; RMSEA<0.001 with CI: 0.001-0.125 and CFI=1.00). Functional outcome at one year follow-up was predicted by the functional outcome at baseline, which in turn, was related to subthreshold depressive symptoms at baseline and to the verbal composite memory scores as a mediator variable. CONCLUSION The results of this study prospectively confirm previous findings on the disabling role of subthreshold depressive symptoms and verbal memory impairment on psychosocial functioning. However, these results come from a sample with moderate to severe functional impairment; hence, as a limitation, this may hinder the generalization of these results.

Abstract
BACKGROUND Patients with remitted bipolar disorder have cognitive impairments, particularly in executive functions. However, the findings of studies that investigated cognitive functions in unaffected relatives of patients with bipolar disorder are conflicting. AIMS The aim of this study is to investigate executive functions in healthy parents of patients with bipolar I disorder, along with bipolar I disorder patients and matched controls. It has been hypothesized that both patients with bipolar I disorder and their parents would have executive function impairments compared with controls. METHODS 25 patients with bipolar I disorder, in full remission, 25 healthy controls that matched the patients with respect to age, gender and education, 50 healthy parents of those patients and 50 healthy controls that matched the parents for age, gender and education were included in the study. All the participants were interviewed with Structured Clinical Interview for DSM-IV-Axis I (SCID-I). Executive functions were assessed using the Verbal Fluency Test (VFT), Trail Making Test (TMT), Wisconsin Card Sorting Test (WCST) and Stroop Test. RESULTS Patients performed significantly worse than their matched controls on the VFT, TMT and Stroop tests, but not on the WCST. Parents performed significantly worse than their matched controls on the TMT and Stroop tests, but not on the VFT and WCST. CONCLUSIONS Our results bring more evidence that deficits in ventral, but not dorsal prefrontal executive functions are associated with familial vulnerability to bipolar disorder and ventral prefrontal executive function impairments may represent a potential endophenotype for bipolar disorder.

Association of rs1006737 in CACNA1C with alterations in prefrontal activation and fronto-hippocampal connectivity. Hum Brain Mapp 2013; 35:1190-200. [PMID: 23404764 DOI: 10.1002/hbm.22244] [Citation(s) in RCA: 67] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2012] [Revised: 11/20/2012] [Accepted: 11/24/2012] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Genome-wide association studies have identified the rs1006737 single nucleotide polymorphism (SNP) in the CACNA1C gene as a susceptibility locus for schizophrenia and bipolar disorder. On the neural systems level this association is explained by altered functioning of the dorsolateral prefrontal cortex (DLPFC) and the hippocampal formation (HF), brain regions also affected by mental illness. In the present study we investigated the association of rs1006737 genotype with prefrontal activation and fronto-hippocampal connectivity. METHODS We used functional magnetic resonance imaging to measure neural activation during an n-back working memory task in 94 healthy subjects. All subjects were genotyped for the SNP rs1006737. We tested associations of the rs1006737 genotype with changes in working-memory-related DLPFC activation and functional integration using a seed region functional connectivity approach. RESULTS Rs1006737 genotype was associated with altered right-hemispheric DLPFC activation. The homozygous A (risk) group showed decreased activation compared to G-allele carriers. Further, the functional connectivity analysis revealed a positive association of fronto-hippocampal connectivity with rs1006737 A alleles. CONCLUSIONS We did not replicate the previous findings of increased right DLPFC activation in CACNA1C rs1006737 A homozygotes. In fact, we found the opposite effect, thus questioning prefrontal inefficiency as rs1006737 genotype-related intermediate phenotype. On the other hand, our results indicate that alterations in the functional coupling between the prefrontal cortex and the medial temporal lobe could represent a neural system phenotype that is mediated by CACNA1C rs1006737 and other genetic susceptibility loci for schizophrenia and bipolar disorder.

Schizotypy and genetic loading for schizophrenia impact upon neuropsychological status in bipolar II and unipolar major depressive disorders. J Affect Disord 2012; 142:225-32.

Abstract
BACKGROUND Growing evidence suggests that schizotypy and genetic loading for schizophrenia both represent risk for the development of schizophrenia. Although these conditions are known to be associated with neurocognitive impairments, such an association has not been studied in patients with bipolar II disorder (BPII) or unipolar major depressive disorder (UP). METHODS Forty-one depressed patients with BPII, 131 patients with UP and demographically matched 225 healthy controls were recruited. Schizotypy was assessed by the Schizotypal Personality Questionnaire. Neuropsychological functioning was measured by the Wechsler Memory Scale-Revised, the Wechsler Adult Intelligence Scale-Revised and the Wisconsin Card Sorting Test. RESULTS Mood disorder patients performed significantly worse than controls in verbal and visual memory, working memory and processing speed. BPII patients performed significantly more poorly than UP patients in verbal memory and executive functioning. Both BPII and UP patients demonstrated significantly greater schizotypal traits than controls. Schizotypy was significantly negatively correlated with verbal comprehension both in BPII and UP patients and with working memory and processing speed in healthy controls. Patients who had one or more first-degree relatives with schizophrenia performed significantly more poorly than the remaining patients in all cognitive domains. LIMITATIONS Most of our patients were on psychotropic medication, and the sample of BPII patients was not very large. CONCLUSIONS Liability for schizophrenia could play a pivotal role in neurocognitive functioning in mood disorders, suggesting that such liability might lie on a continuum ranging from normality through mood disorders to full-blown schizophrenia.

Abstract
Neuropsychiatric illnesses are associated with dysfunction in distributed prefrontal neural systems that underlie perception, cognition, social interactions, emotion regulation, and motivation. The high degree of learning-dependent plasticity in these networks-combined with the availability of advanced computerized technology-suggests that we should be able to engineer very specific training programs that drive meaningful and enduring improvements in impaired neural systems relevant to neuropsychiatric illness. However, cognitive training approaches for mental and addictive disorders must take into account possible inherent limitations in the underlying brain 'learning machinery' due to pathophysiology, must grapple with the presence of complex overlearned maladaptive patterns of neural functioning, and must find a way to ally with developmental and psychosocial factors that influence response to illness and to treatment. In this review, we briefly examine the current state of knowledge from studies of cognitive remediation in psychiatry and we highlight open questions. We then present a systems neuroscience rationale for successful cognitive training for neuropsychiatric illnesses, one that emphasizes the distributed nature of neural assemblies that support cognitive and affective processing, as well as their plasticity. It is based on the notion that, during successful learning, the brain represents the relevant perceptual and cognitive/affective inputs and action outputs with disproportionately larger and more coordinated populations of neurons that are distributed (and that are interacting) across multiple levels of processing and throughout multiple brain regions. This approach allows us to address limitations found in earlier research and to introduce important principles for the design and evaluation of the next generation of cognitive training for impaired neural systems. We summarize work to date using such neuroscience-informed methods and indicate some of the exciting future directions of this field.

Abstract
Bipolar disorder is a severe mental illness that affects nearly 4.4% of the general population when bipolar spectrum disorders are taken into account. Neurocognitive impairment is thought to be a core deficit of this illness since it is present during euthymia. In fact, 40-60% of euthymic patients present with neurocognitive disturbances. Not only the clinical factors but also disturbances in neurocognition can influence the functional outcome of BD patients. Hence, further research is needed in order to clarify the relationship between these variables. Despite the growing body of evidence that has emerged during the last decade, no unique neurocognitive profile has been proposed yet for either BD subtype. The majority of the studies recluted heterogeneous samples (including both bipolar I and II) or focused on BD-I patients only. The aim of this review is to give an overall picture of the main neurocognitive disturbances found in the bipolar spectrum and particularly in BD-II, where the findings are more ambiguous. An extensive review of all the literature has been done regarding this subtype (from 1980 until July 2009). Data available until now suggest that deficits are present across the bipolar spectrum (BD-I and BD-II), but they seem slightly more severe in BD-I. The extent to which either subtype share-or not-some similarities is still unknown. More studies are required but it would also be interesting to reach a consensus in the neuropsychological assessment of BD to facilitate comparisons between the different studies.

Abstract
OBJECTIVE We examined the use of particular cognitive strategies for regulating negative emotion in relation to mood and temperament in BD-I, unaffected relatives of bipolar patients (UR), and healthy controls (HC). METHOD Participants were 105 patients with BD-I, 124 UR, and 63 HC; all participants completed the Cognitive Emotion Regulation Questionnaire (CERQ), the Depression Anxiety Stress Scales (DASS), and the Hypomanic Personality Scale (HPS). RESULTS The BD-I group reported more frequent use of rumination, catastrophizing and self-blame, and less frequent use of putting into perspective, in response to negative life events, relative to the UR and HC groups. In BD-I, more frequent use of rumination was associated with increased DASS and HPS scores. By contrast, within the UR group, more frequent use of catastrophizing and self-blame were associated with increased DASS and HPS scores. In all participants, less frequent use of adaptive cognitive reframing strategies (e.g. putting into perspective) were associated with increased DASS scores. CONCLUSION Both BD-I and UR groups reported more frequent use of maladaptive regulatory strategies previously associated with depression. Emotion regulation strategies of catastrophizing, self-blame, and cognitive reframing techniques may be associated with vulnerability for mood disorders, with the latter active within the general population regardless of biological vulnerability to disorder.
