RESUMEN
OBJECTIVE: The support of the personal recovery of people with lived experience of mental illness is a major issue in clinical practice. Thus, a valid instrument to assess personal recovery is needed. The present study aimed to validate the French translation of the 22-item Questionnaire about the Process of Recovery (QPR-Fr). METHOD: A convenience sample of 222 participants reporting a severe mental illness diagnosis was recruited online. Psychometric properties of the QPR-Fr were evaluated. A confirmatory factor analysis was conducted for structural validity. Internal consistency and test-retest reliability were assessed. To test for convergent validity, we conducted multiple linear regression analysis to explore the QPR-Fr associations with psychological distress and the CHIME framework (with Connectedness, Hope and optimism about the future, Identity, Meaning in life, and Empowerment) proxy measures (perceived social support, hope, self-esteem, quality of life, and empowerment). RESULTS: An adequate fit was found for a 19-item unidimensional factor structure. Internal consistency was excellent. Test reliability was good. The QPR-Fr total score was significantly positively associated with quality of life, hope, self-esteem, and social support satisfaction and negatively associated with psychological distress. No significant association was found with social support availability nor with empowerment. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: This study provides additional data to support the cross-cultural validity of the Questionnaire about the Process of Recovery. The QPR-Fr is a valid and reliable tool to assess personal recovery. Practitioners could use the QPR-Fr to assess personal recovery in collaboration with people with lived experience. Convergent validity with CHIME proxy measures supports the validity of the CHIME framework in a French cultural context. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVES: Although free from characterized manic and depressive episodes, the euthymic period in bipolar disorder (BD) remains characterized by a whole host of difficulties, particularly relational. These difficulties are factors of vulnerabilities and relapses. People's perception of their own relationships has an impact on their symptomatology, their responses to treatment and on relapse rates. Young's early maladaptive schemas (EMS) approach proves to be relevant for understanding the construction of these perceptions and working on them. Nevertheless, to this date, few studies have investigated which EMS are related to relationship dysfunction in this particular population. Determining the link between EMS and relationship difficulties would be relevant to understand psychosocial impairment of people with BD in euthymic states. The present study aims to investigate the associations between the different domains of EMS and relationship dysfunction among patients with bipolar disorder in the euthymic phase. METHODS: Data are extracted from the FACE-BD cohort, within the BD Expert Center in Versailles. Inclusion criteria were to be aged between 18 and 65 and to be an outpatient with a diagnosis of bipolar disorder (DSM-IV-TR). Patients had to be euthymic at the time of inclusion, according to DSM-IV-TR criteria with a cut-off score of 14 on the Montgomery-Asberg Depression Rating Scale and the Young Mania Rating Scale. Non-inclusion criteria were meeting at the time of the study the criteria for characteristic depressive episode, hypomania or mania according to the DSM-IV-TR. Sociodemographic data, clinical features associated with relationship dysfunction were assessed. EMS and EMS domains were assessed with the YSQ-R short form (Young Schema Questionnaire 3 Short Form) and current relationship dysfunction were assessed with the FAST (Functioning assessment short test subscale). Successive simple linear regression analyses were performed to investigate the association between the severity scores of each EMS and the intensity of relationship dysfunction. Furthermore, successive simple linear regression analyses investigated the association between EMS domain scores and intensity of relationship dysfunction. Multiple linear regression analyses were performed to test the association between EMS scores, then EMS domains, and the intensity of relationship dysfunction after adjusting for age as well as the intensity of residual depressive and manic symptoms. RESULTS: Relationship dysfunction is partly associated with EMS activation in particular in the separation and rejection domain (P<0.0001), the other-directedness domain (P=0.031) and the over-vigilance and inhibition domain (P=0.005). Having residual depressive symptoms is also among the factors contributing to the relationship dysfunctions of people with bipolar disorder in the euthymic phase. DISCUSSION: This is the first study demonstrating that the activation of several domains of EMS is a risk factor of relationships difficulties for people in euthymic phase of bipolar disorder. It is necessary to identify which EMS are specifically activated and their domains of belonging in order to prevent and reduce them. EMS are a lever for functional remission. It is therefore relevant to refer people reporting relationship problems to schema therapy consistent with a personalized care. Finally, future studies should focus on the mechanisms underlying the complex relationship between EMS domains and relationship dysfunction in people with bipolar disorder in the euthymic phase. It may also be relevant for future research to control for different types of relationship dysfunction. EMS may be differentially associated with several types of interpersonal problems. The relations between different adaptation styles and EMS should be further investigated to offer more personalized care, with the aim to improve functional remission.
RESUMEN
In order to determine family functioning in the treatment of adults with bipolar disorders, guidelines are needed regarding the way family functioning may be assessed. The present systematic review aims to investigate how family functioning is assessed in this context. Following PRISMA guidelines, a total of 29 studies were reviewed. Results showed that although there was no consensual family functioning assessment across studies, 27 studies (93%) relied on self-report questionnaires, 12 studies (41%) relied on one family member as an informant (adult with bipolar disorder or other) and the adult considered was mostly a woman in the acute phase of bipolar I disorder. Significant heterogeneity was observed in the assessment of family functioning. Methodological considerations regarding the assessment of family functioning are discussed.
RESUMEN
In patients with bipolar disorder (BD), pain prevalence is close to 30%. It is important to determine whether pain influences BD course and to identify factors associated with pain in BD in order to guide BD management. This naturalistic, prospective study used data on 880 patients with BD from the French FACE-BD cohort who were divided into two groups according to the presence or absence of pain. Multivariate models were used to test whether pain was associated with affective states and personality traits while controlling for confounders. Then, multivariate models were used to test whether pain at baseline predicted global life functioning and depressive symptomatology at one year. At baseline, 22% of patients self-reported pain. The pain was associated with depressive symptomatology, levels of emotional reactivity in a quadratic relationship, and a composite variable of personality traits (affective lability, affective intensity, hostility/anger, and impulsivity). At one year, the pain was predictive of depression and lower global life functioning. Pain worsens mental health and well-being in patients with BD. The role of emotions, depression, and personality traits in pain has to be elucidated to better understand the high prevalence of pain in BD and to promote specific therapeutic strategies for patients experiencing pain.
RESUMEN
OBJECTIVES: Childhood maltreatment, also referred as childhood trauma, increases the severity of bipolar disorders (BD). Childhood maltreatment has been associated with more frequent mood recurrences, however, mostly in retrospective studies. Since scarce, further prospective studies are required to identify whether childhood maltreatment may be associated with the time to recurrence in BD. METHODS: Individuals with BD (N = 2008) were assessed clinically and for childhood maltreatment at baseline, and followed up for two years. The cumulative probability of mood recurrence over time was estimated with the Turnbull's extension of the Kaplan-Meier analysis for interval-censored data, including childhood maltreatment as a whole, and then maltreatment subtypes as predictors. Analyses were adjusted for potential confounding factors. RESULTS: The median duration of follow-up was 22.3 months (IQR:12.0-24.8). Univariable analyses showed associations between childhood maltreatment, in particular all types of abuses (emotional, physical, and sexual) or emotional neglect, and a shorter time to recurrence (all p < 0.001). When including potential confounders into the multivariable models, the time to mood recurrence was associated with multiple/severe childhood maltreatment (i.e., total score above the 75th percentile) (HR = 1.32 95%CI (1.11-1.57), p = 0.002), and more specifically with moderate/severe physical abuse (HR = 1.44 95%CI(1.21-1.73), p < 0.0001). Living alone, lifetime anxiety disorders, lifetime number of mood episodes, baseline depressive and (hypo)manic symptoms, and baseline use of atypical antipsychotics were also associated with the time to recurrence. CONCLUSIONS: In addition to typical predictors of mood recurrences, an exposure to multiple/severe forms of childhood maltreatment, and more specifically to moderate to severe physical abuse, may increase the risk for a mood recurrence in BD. This leads to the recommendations of more scrutiny and denser follow-up of the individuals having been exposed to such early-life stressors.

INTRODUCTION: Tobacco and alcohol represent the two most important risk factors increasing cancer incidence and mortality, particularly among women with breast cancer. However, few researches have focused on the consumption of psychoactive substances in women treated for breast cancer. The present study describes the prevalence of tobacco and alcohol consumption and their relationships with the sociodemographic, medical and psychological variables in a population of women receiving surgery treatment for breast cancer. METHODS: Between October 2014 and August 2015, a group of women receiving breast cancer treatment were recruited to participate to a screening and brief intervention program (SBI) for the consumption of tobacco and alcohol, adapted to the oncology context. Data on tobacco and alcohol consumption were collected using two questionnaires : the smoking status identification (NIDA) and alcohol consumption (AUDIT-C). A questionnaire for socio- demographic data and two for psychological data (Thermometer of psychological distress; ESAS), have been used. The medical data were reported by participants and verified on medical records. RESULTS: In a total of 11 months, 120 women with breast cancer were included in this study. A large majority of patients were hospitalized for a first-time cancer (80.8%), type invasive ductal carcinoma (70.8%) and were receiving surgery as primary treatment (45%). Furthermore, 30.8% of the women reported tobacco consumption and 38.4% high-risk alcohol consumption. Regarding mental health, 40.8% presented moderate to intense levels of psychological distress. No significant relationships were found between consumption scores and sociodemographic, medical or psychological characteristics. Only the patient's age was negatively associated with tobacco consumption. DISCUSSION: Tobacco and at-risk alcohol consumption are frequently reported behaviors during breast cancer treatment. Intervention strategies targeting risk behaviors related to addictive consumption should be implemented during the full treatment of breast cancer patients.

OBJECTIVES: The comorbidity of alcohol use disorder (AUD) and bipolar disorder (BD) has been repeatedly associated with poorer clinical outcomes than BD without AUD. We aimed to extend these findings by focusing on the characteristics associated with the sequence of onset of BD and AUD. METHODS: 3,027 outpatients from the Fondamental Advanced Centres of Expertise were ascertained for BD-1, BD-2 and AUD diagnoses, including their respective ages at onset (AAOs, N =2,804). We selected the variables associated with both the presence and sequence of onset of comorbid AUD using bivariate analyses corrected for multiple testing to enter a binary regression model with the sequence of onset of BD and AUD as the dependent variable (AUD first - which also included 88 same-year onsets, vs. BD first). RESULTS: BD patients with comorbid AUD showed more severe clinical profile than those without. Compared to BD-AUD (N =269), AUD-BD (N =276) was independently associated with a higher AAO of BD (OR =1.1, p <0.001), increased prevalence of comorbid cannabis use disorder (OR =2.8, p <0.001) a higher number of (hypo)manic/mixed BD episodes per year of bipolar illness (OR =3, p <0.01). LIMITATIONS: The transversal design prevents from drawing causal conclusions. CONCLUSION: Increased severity of BD with AUD compared to BD alone did not differ according to the sequence of onset. A few differences, though, could be used to better monitor the trajectory of patients showing either one of these disorders.

BACKGROUND: Bipolar disorder (BD) is a chronic and severe mental illness. It requires a non-discontinued pharmacological treatment to prevent mood recurrences but nonadherence to medication is frequent. To this date, medication adherence in BD has been mostly evaluated in cross-sectional studies and often considered as a stable trait. We aimed to study medication adherence using a prospective person-oriented approach. METHODS: 1627 BD patients were followed on a 2 years period and assessed every 6 months. Medication adherence was evaluated at each visit with the Medication Adherence Rating Scale (MARS). A latent class mixed model (LCMM) was used to identify trajectory classes of adherence over time. Regression analyses and linear mixed model were used to search for predictors and covariables of the trajectories. RESULTS: Three distinct and robust trajectories of medication adherence have been identified: one that starts poorly and keeps deteriorating (4.8%), one that starts poorly but improves (9%) and one that starts well and keeps improving (86.2%). A good tolerance to psychotropic medications, low depressive symptoms, the absence of comorbid eating disorders and anticonvulsant medication were associated to a better prognosis of adherence. Along the follow-up, the lower were the depressive symptoms, the better was the medication adherence (p < .001) LIMITATIONS: The use of a single measure of medication adherence although it is a validated instrument and a possible positive selection bias that might limit the generalization of our findings. CONCLUSIONS: This study demonstrates that medication adherence in BD patients is a heterogeneous and potentially variable phenomenon.

BACKGROUND: A crucial health issue is to understand the remission heterogeneity of Bipolar Disorders by considering symptomatology as well as functioning. A new perspective could be elements of the construction of individual identity. This exploratory study aimed to explore the remission heterogeneity of patients with BD in terms of Early Maladaptive Schemas (EMS) by preferring a person-oriented approach. METHODS: This study included euthymic patients recruited into the FACE-BD cohort. The remission was assessed by the Montgomery-Asberg Depression Rating Scale and the Young Mania Rating Scale for its symptomatic dimension and by the Functioning Assessment Short Test for its functional dimension. The activation of the eighteen EMS was assessed by the Young Schema Questionnaire 3 Short Form. Clustering was performed to identify profiles according to the patients' remission. Clusters identified were compared on the EMS activation by using analysis of variance and post-hoc tests. RESULTS: Among the 100 euthymic patients included, four profiles of remission were identified: cluster 1 "Global Remission" (34%), cluster 2 "Hypomanic residual" (20%), cluster 3 "Depressive residual and functional impairment" (36%) and cluster 4 "Global handicap" (10%). Two out of three EMS discriminated against these profiles. The activation of specific EMS clarifies the singularity of each remission profile. LIMITATIONS: For the symptomatic dimension, cut-offs chosen could be discussed as well as the scale assessing residual depressive symptoms. CONCLUSIONS: This study participates in a comprehensive model of remission by integrating the symptomatology, the functioning, and the EMS. Identifying and treating EMS may improve patients remission to reach recovery.

BACKGROUND: Cognitive deficits are a well-established feature of bipolar disorders (BD), even during periods of euthymia, but risk factors associated with cognitive deficits in euthymic BD are still poorly understood. We aimed to validate classification criteria for the identification of clinically significant cognitive impairment, based on psychometric properties, to estimate the prevalence of neuropsychological deficits in euthymic BD, and identify risk factors for cognitive deficits using a multivariate approach. METHODS: We investigated neuropsychological performance in 476 euthymic patients with BD recruited via the French network of BD expert centres. We used a battery of tests, assessing five domains of cognition. Five criteria for the identification of neuropsychological impairment were tested based on their convergent and concurrent validity. Uni- and multivariate logistic regressions between cognitive impairment and several clinical and demographic variables were performed to identify risk factors for neuropsychological impairment in BD. RESULTS: One cut-off had satisfactory psychometric properties and yielded a prevalence of 12.4% for cognitive deficits in euthymic BD. Antipsychotics use were associated with the presence of a cognitive deficit. CONCLUSIONS: This is the first study to validate a criterion for clinically significant cognitive impairment in BD. We report a lower prevalence of cognitive impairment than previous studies, which may have overestimated its prevalence. Patients with euthymic BD and cognitive impairment may benefit from cognitive remediation.

The aim of this study was to assess the respective weight of individual and environmental factors on quality of life (Qol) of parents of children with autism spectrum disorders (ASD). Few studies have investigated both individual and environmental predictors of Qol but to our knowledge, none of them has considered the child's and parents' characteristics, family context and services available in the same design. Participants were 115 parents (73 mothers and 42 fathers) of children with ASD aged from 3 to 10 years. Hierarchical regression analyses were conducted to investigate predictors of parental Qol among child-related, parent-related and environmental factors. Findings indicate that a higher Qol is associated with a good quality of interaction in marital and parent-grandparents dyads, no family medical history and access to psycho-educational interventions for the child, regardless of child's developmental quotient, comorbidity, parent sex and working time. This final model best fits the data and explains 31.5% of the variance of parents' Qol. This study highlights that it is crucial to consider both individual and environmental variables as potential protective factors of parental adjustment. An ecological approach seems to be relevant to understand which parenting resources should be targeted in support programs.

BACKGROUND: Reducing risk attributable to traffic accidents is a public health challenge. Research into risk factors in the area is now moving towards identification of the psychological factors involved, particularly emotional states. The aim of this study was to evaluate the link between emotional reactivity and responsibility in road traffic accidents. We hypothesized that the more one's emotional reactivity is disturbed, the greater the likelihood of being responsible for a traffic accident. METHODS: This case-control study was based on a sample of 955 drivers injured in a motor vehicle crash. Responsibility levels were determined with a standardized method adapted from the quantitative Robertson and Drummer crash responsibility instrument. Emotional reactivity was assessed with the MATHYS. RESULTS: Hierarchical cluster analysis discriminated four distinctive driver's emotional reactivity profiles: basic emotional reactivity (54%), mild emotional hyper-reactivity (29%), emotional hyper-reactivity (11%) and emotional hypo-reactivity (6%). Drivers who demonstrated emotional hypo-reactivity had a 2.3-fold greater risk of being responsible for a traffic accident than those with basic emotional reactivity. CONCLUSION: Drivers' responsibility in traffic accidents depends on their emotional status. The latter can change the ability of drivers, modifying their behavior and thus increasing their propensity to exhibit risk behavior and to cause traffic accidents.

OBJECTIVES: Poor adherence to medication is frequent in bipolar disorder (BD) and has been associated with several factors. To date, the relationship between low adherence and neuropsychological functioning in BD is still unclear. As age and neuropsychological functioning might have opposing influences on adherence, our aim was to investigate this link with a particular focus on the effect of age. METHODS: In a cross-sectional study, we included 353 patients divided into two age-groups (16-46; 47-71) from a French cohort diagnosed with BD (type I, II, NOS) and strictly euthymic. All patients had a standardized clinical and neuropsychological assessment and were categorized as high (n = 186) or low (n = 167) adherent based on their score from the Medication Adherence Rating Scale. Clinical information was collected based on a standardized interview and clinical validated scales. Neuropsychological performances were evaluated with an established standardized neuropsychological battery for bipolar disorder patients. After univariate analysis, neuropsychological and clinical predictors of low adherence were included in two age-specific stepwise multiple logistic regressions. RESULTS: A smaller number of hospitalizations (OR = 0.846, p = 0.012), a shorter illness duration (OR = 0.937, p = 0.003) and higher adverse effects (OR = 1.082, p<0.001) were associated with a greater risk of low adherence in the younger patients. In the older patients, low adherence was also predicted by a smaller number of hospitalizations (OR = 0.727, p = 0.008) and higher adverse effects (OR = 1.124, p = 0.005). Interestingly poor inhibition performance was also a significant predictor of low adherence in older patients (OR = 0.924, p = 0.030). CONCLUSIONS: We found an age-specific relationship between cognitive functioning and adherence in patients with BD. Poor inhibition performances predicted low adherence in older patients only. Our results highlight the need to provide age-adapted therapeutic interventions to improve adherence in patients with BD.

OBJECTIVES: To describe the various types of patient education interventions for colorectal cancer patients with stoma and to examine their effects on quality of life, psychosocial skills and self-management skills. METHODS: A systematic review was performed. Six electronic databases were searched. Inclusion criteria were: studies about patient education applying quantitative methods including digestive stoma adults with colorectal cancer. The primary outcome was quality of life. Secondary outcomes were psychosocial and self-management skills. RESULTS: Thirteen studies were identified and included. Five studies examined quality of life and three reported improvements. Patient education improved some psychosocial and self-management skills. Contrasting findings were reported for specific-disease quality of life, emotional distress, length of hospital stay, stoma complications and readmission rate. CONCLUSIONS: Patient education has a positive impact on some psychosocial and self-management skills, indicating that this area should be developed. Contrasting findings were reported for quality of life. Methodologies are heterogeneous making it difficult to produce evidence-based guidelines. This article proposes tools to carry out further studies on this subject and to improve understanding. PRACTICE IMPLICATION: Further education intervention for stoma patients with colorectal cancer should be standardized in terms of intervention, duration and outcome measures to compare intervention and determine best practice.

OBJECTIVES: Inter-episode mood instability has increasingly been considered in bipolar disorder. This study aimed to investigate emotional reactivity as a major dimension for better characterizing remitted bipolar patients with subthreshold mood symptoms and functional status. This study also aimed to investigate whether high-sensitivity C-reactive protein, a marker of low-grade inflammation, could be a biological marker of emotional dysregulation in bipolar disorder (BD). METHODS: Cross-sectional study of 613 subjects who met Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria for BD recruited from the FondaMental Advanced Centers of Expertise in Bipolar Disorders cohort from 2009 to 2014. All patients had been in remission for at least 3 months before assessment. Patients were classified into three groups according to levels of emotional reactivity. Emotional reactivity was assessed by using the Multidimensional Assessment of Thymic States, and functional status was assessed by the Functioning Assessment Short Test. Clinical characteristics and blood sample were collected from all patients. RESULTS: In total, 415 (68%) patients had abnormal emotional reactivity. Independent of potential confounders, including age, gender and subthreshold mood symptoms, serum levels of high-sensitivity C-reactive protein were significantly higher in patients with emotional hyper-reactivity (median = 4.0 mg/L, interquartile range = 2.7-5.6), and with emotional hypo-reactivity (median = 3.0 mg/L, interquartile range = 1-4) compared with patients with normal emotional reactivity (median = 0.95 mg/L, interquartile range = 0.4-1.9, p < 0.001). Patients with emotional hyper-reactivity showed significant cognitive functioning impairment ( p < 0.001). CONCLUSIONS: Emotional reactivity appears to be a relevant dimension for better characterizing remitted bipolar patients with subthreshold mood symptoms. Levels of high-sensitivity C-reactive protein may be an objective marker of emotional dysregulation in BD. Further studies are needed to confirm our findings.

To better explore the clinical heterogeneity of bipolar mood states, we developed a dimensional scale for assessing all mood episodes (depressive, hypomanic, manic, mixed states) using the same tool. The Multidimensional Assessment of Thymic States (MATHYS) (Henry et al., 2008) provides two scores, a total score measuring a level of activation and a sub-score of emotional reactivity. The aim of this study was to establish the appropriate cut-off in total activation versus inhibition and in the emotional reactivity sub-score in bipolar disorders. Patients (n=187) during an acute episode and controls (n=89) filled in the MATHYS. Receiver Operating Characteristic (ROC) curves were obtained to estimate the sensitivity and specificity of the global score and the emotional reactivity sub-score of the MATHYS, in order to differentiate patients from controls. ROC curves showed very satisfactory sensitivity and specificity levels both for the total score and the sub-score of emotional reactivity, thus providing an appropriate cut-off. Concerning the total score between 0 and 200, patients with a score lower than 91 had significant global inhibition and those with a score higher than 109 had significant global activation. Regarding the emotional reactivity sub-score between 0 and 40, patients with a score lower than 16 had significant emotional hyporeactivity and those with a score higher than 24 had significant emotional hyperreactivity. Our results provide cut-offs for the MATHYS to identify patients in an acute phase.

BACKGROUND: Pattern analysis can aid understanding of trajectories of symptom evolution. However, most studies focus on relatively homogeneous disorders with a restricted range of outcomes, prescribed a limited number of classes of medication. We explored the utility of pattern analysis in defining short-term outcomes in a heterogeneous clinical sample with acute bipolar disorders. METHOD: In a naturalistic observational study, we used Group-based trajectory modeling (GBTM) to define trajectories of symptom change in 118 bipolar cases recruited during an acute DSM IV episode: major depression (56%), (hypo)mania (26%), and mixed states (18%). Symptoms were assessed weekly for a month using the MATHYS, which measures symptoms independent of episode polarity. RESULTS: Four trajectories of symptom change were identified: Persistent Inhibition, Transient Inhibition, Transient Activation and Over-activation. However, counter to traditional predictions, we observed that bipolar depression shows a heterogeneous response pattern with cases being distributed approximately equally across trajectories that commenced with inhibition and activation. LIMITATIONS: The observational period focuses on acute outcomes and so we cannot use the findings to predict whether the trajectories lead to stable improvement or whether the clinical course for some clusters is cyclical. As in all GBTM, the terms used for each trajectory are subjective, also the modeling programme we used assumes dropouts are random, which is clearly not always the case. CONCLUSION: This paper highlights the potential importance of techniques such as GBTM in distinguishing the different response trajectories for acutely ill bipolar cases. The use of the MATHYS provides further critical insights, demonstrating that clustering of cases with similar response patterns may be independent of episodes defined by mood state.

OBJECTIVE: To assess the association between mind wandering (thinking unrelated to the task at hand) and the risk of being responsible for a motor vehicle crash. DESIGN: Responsibility case-control study. SETTING: Adult emergency department of a university hospital in France, April 2010 to August 2011. PARTICIPANTS: 955 drivers injured in a motor vehicle crash. MAIN OUTCOME MEASURES: Responsibility for the crash, mind wandering, external distraction, negative affect, alcohol use, psychotropic drug use, and sleep deprivation. Potential confounders were sociodemographic and crash characteristics. RESULTS: Intense mind wandering (highly disrupting/distracting content) was associated with responsibility for a traffic crash (17% (78 of 453 crashes in which the driver was thought to be responsible) v 9% (43 of 502 crashes in which the driver was not thought to be responsible); adjusted odds ratio 2.12, 95% confidence interval 1.37 to 3.28). CONCLUSIONS: Mind wandering while driving, by decoupling attention from visual and auditory perceptions, can jeopardise the ability of the driver to incorporate information from the environment, thereby threatening safety on the roads.

BACKGROUND: Assessment of emotional reactivity, defined as rapid emotional responses to salient environmental events, has been neglected in mood disorders. This article reviews data showing the relevance of using emotional reactivity to better characterize bipolar mood episodes. METHOD: We reviewed clinical data on emotional reactivity during all phases of bipolar disorders (euthymic, manic, mixed and depressive states) and brain-imaging, neurochemical, genetic studies related to emotional reactivity disturbances. RESULT: Euthymic bipolar patients show mild abnormalities (hypersensitivity to emotional stimuli and higher arousability) in comparison to controls. Both manic and mixed states are characterized by a significant increase in emotional reactivity. Furthermore, emotional reactivity may discriminate between two types of bipolar depression, the first being characterized by emotional hypo-reactivity and global behavioral inhibition, the second by emotional hyper-reactivity. Brain-imaging studies can help to identify the underlying mechanisms involved in disturbances of emotional reactivity. CONCLUSION: Emotional reactivity can be used to refine more homogeneous pathophysiological subtypes of mood episodes. Future research should explore possible correlations between biomarkers, response to treatments and these clinical phenotypes.

BACKGROUND: The clinical presentation, course, and comorbidities of bipolar disorder type I are highly heterogeneous, and this variability remains poorly predictable. Certain onset characteristics (eg, age and polarity at onset) may delineate subgroups differing in clinical expression and outcome. METHOD: We retrospectively investigated the association between both age and polarity at onset and the clinical characteristics of bipolar I disorder (DSM-IV) in 2 independent adult samples: 480 French patients assessed in 1992-2006 (patients had been recruited from 3 university-affiliated psychiatry departments) and 714 US patients assessed in 1991-2003 (data were extracted from the Bipolar Disorder Phenome Database). RESULTS: Polarity at onset correlated with subsequent predominance (P < .001). Most patients experienced a depressive onset (57.9% in France vs 71.0% in the United States; P < .001) associated with a higher density of depressive episodes, suicidal behavior, and alcohol misuse. A manic onset was associated with a higher density of manic episodes. Early onset was frequent in both countries (42% in France vs 68% in the United States; P < .001) and was associated with suicidal behavior and cannabis and cocaine/opiate misuse. Sensitivity for the prediction of clinical characteristics was 1%-35% for age at onset and 26%-47% for polarity at onset. CONCLUSIONS: Onset characteristics are associated with subsequent predominant polarity, suicidal behavior, and substance misuse in bipolar I disorder. These findings may facilitate personalized treatment strategies based on type of onset and may also facilitate early focused strategies for preventing comorbidity. Given the relatively low sensitivity and specificity of these onset characteristics for predicting clinical variables, the relevance of age and polarity at onset as specifiers in nosographical classifications will require further studies. However, polarity at onset may be the more relevant specifier, with further investigation required for age at onset.
