Objective: Prior studies support that younger age of onset would be associated with poorer psychiatric and mental health outcomes for many psychiatric disorders. However, such relationship has never been examined for social anxiety disorder (SAD) in a nationally representative sample., Methods: Using data from the second Wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), we have identified four groups of participants with a lifetime DSM-IV diagnosis of SAD based on the self-reported age of onset (childhood onset (<12 years, N = 658), adolescence onset (12-17 years, N = 663), early-adulthood onset (18-39 years, N = 663), and late-adulthood onset (>39 years, N = 415)), and a control group without a lifetime history of SAD (N = 32,205). We performed multinomial logistic regression models to compare lifetime DSM-IV psychiatric disorders and current mental health-related quality of life (assessed with the mental component summary score (MSC) of the SF-12) across these groups., Results: The lifetime prevalence rates of panic disorder, agoraphobia and post-traumatic stress disorder were significantly higher in the adulthood onset groups than in groups with an onset during childhood or adolescence (p < 0.01 for most models). MCS score was significantly higher in the childhood (46.0 (SE = 0.5)) or adolescence (46.5 (SE = 0.5)) onset groups than in the groups with an onset during adulthood (early-adulthood onset: 43.5 (SE = 0.6), and late-adulthood onset: 43.0 (SE = 0.8))., Limitations: Our results relied on retrospective self-reported data., Conclusion: Among individuals with SAD, a later age of onset was significantly associated with greater lifetime rates of psychiatric disorders and diminished quality of life., (Copyright © 2022.

Introduction: It remains unclear whether specific clinical factors contribute to heterogeneity in the timing of the onset of major depression., Methods: Using a nationally representative US adult sample, the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions, we compared the characteristics of 5 different groups of patients defined by their age at onset: (i) before 18 years, (ii) between 18 and 34 years, (iii) between 35 and 44 years, (iv) between 45 and 59 years, and (v) 60 years or older. Specifically, we examined parental history of psychiatric disorders, history of childhood maltreatment experiences, sociodemographic characteristics, lifetime psychiatric disorders, and psychiatric disorders that occurred before the first major depressive episode (MDE)., Results: Compared with first MDE occurring between 18 and 34 years, first MDE before 18 years was more strongly associated with childhood maltreatment and family history of psychiatric disorders, and less strongly linked to prior lifetime psychiatric disorders, whereas first MDE occurring at 60 years and older was more strongly associated with widowhood and a prior lifetime history of generalized anxiety disorder., Limitations: Associations found cannot be interpzreted as causal relationships due to study design and the risk of recall bias., Conclusion: Our results suggest substantial age differences in risk factors for first MDE. Improving early detection and treatment of major depression and other psychiatric disorders, and preventing childhood maltreatment may have broad benefits to reduce the burden of MDE at all ages., (Copyright © 2021.

Objective: Data are scarce regarding the clinical factors associated with utilization of long-term care facilities among older adults with schizophrenia. In this multicenter study, we sought to examine potential clinical differences between older adults with schizophrenia who are living in a long-term care facility and their community-dwelling counterparts., Method: We used data from the French Cohort of individuals with Schizophrenia Aged 55-years or more (CSA) study, a large multicenter sample of older adults with schizophrenia (N = 353)., Results: The prevalence of long-term care utilization was 35.1% of older patients with schizophrenia. Living in a long term care facility was significantly and independently associated with higher level of depression (Adjusted odds ratio (AOR) [95%CI]=1.97 [1.06-3.64]), lower cognitive (AOR [95%CI]=0.94 [0.88-0.99]) and global functioning (AOR [95%CI]=0.97 [0.95-0.99]), greater lifetime number of hospitalizations in a psychiatric department (AOR [95%CI]=2.30 [1.18-4.50]), not having consulted a general practitioner in the past year (AOR [95%CI]=0.28 [0.0.14-0.56]), urbanicity (AOR [95%CI]=2.81 [1.37-5.80]), and older age (AOR [95%CI]=1.08 [1.03-1.13])., Discussion: Older patients with schizophrenia who live in long-term care facilities appear to belong to a distinct group, marked by a more severe course of illness with higher level of depression and more severe cognitive deficits than older patients with schizophrenia living in other settings. Our study highlights the need of early assessment and management of depression and cognitive deficits in this population and the importance of monitoring closely this vulnerable population., (Copyright © 2021 Elsevier B.V.

Objective: Although lithium is widely used in current practice to treat bipolar disorder (BD) and treatment-resistant major depressive disorder (MDD) among older adults, little is known about its efficacy and tolerability in this population, which is generally excluded from randomized clinical trials. The objective of this study was to evaluate the efficacy and tolerability of long-term use of lithium among older adults with BD and MDD., Method: Data from the Cohort of individuals with Schizophrenia and mood disorders Aged 55 years or more (CSA) were used. Two groups of patients with BD and MDD were compared: those who were currently receiving lithium versus those who were not. The effects of lithium on psychiatric (i.e., depressive symptoms severity, perceived clinical severity, rates of psychiatric admissions in the past-year), geriatric (overall and cognitive functioning) and physical outcomes (i.e., rates of non-psychiatric medical comorbidities and general hospital admissions in the past-year) were evaluated. All analyses were adjusted for age, sex, duration of disorder, diagnosis, smoking status, alcohol use, and use of antipsychotics, antiepileptics or antidepressants., Results: Among the 281 older participants with BD or MDD, 15.7% were taking lithium for a mean duration of 12.5(SD = 11.6) years. Lithium use was associated with lower intensity of depressive symptoms, reduced perceived clinical global severity and lower benzodiazepine use (all p < 0.05), without being linked to greater rates of medical comorbidities, except for hypothyroidism., Limitations: Data were cross-sectional and data on lifetime history of psychotropic medications was not assessed., Conclusion: Our results suggest that long-term lithium use may be efficient and relatively well-tolerated in older adults with BD or treatment-resistant MDD., (Copyright © 2019 Elsevier B.V.

Background: Little is known about the respective effects of depression and cognitive impairment on quality of life among older adults with schizophrenia spectrum disorder., Methods: We used data from the Cohort of individuals with Schizophrenia Aged 55-years or more (CSA) study, a large multicenter sample of older adults with schizophrenia or schizoaffective disorder (N = 353). Quality of life (QoL), depression and cognitive impairment were assessed using the Quality of Life Scale (QLS), the Center of Epidemiologic Studies Depression scale and the Mini-Mental State Examination, respectively. We used structural equation modeling to examine the shared and specific effects of depression and cognitive impairment on QoL, while adjusting for sociodemographic characteristics, general medical conditions, psychotropic medications and the duration of the disorder., Results: Depression and cognitive impairment were positively associated (r = 0.24, p < 0.01) and both independently and negatively impacted on QoL (standardized β = -0.41 and β = -0.32, both p < 0.01) and on each QLS quality-of-life domains, except for depression on instrumental role and cognitive impairment on interpersonal relations in the sensitivity analyses excluding respondents with any missing data. Effects of depression and cognitive impairment on QoL were not due to specific depressive symptoms or specific cognitive domains, but rather mediated through two broad dimensions representing the shared effects across all depressive symptoms and all cognitive deficits, respectively., Limitations: Because of the cross-sectional design of this study, measures of association do not imply causal associations., Conclusions: Mechanisms underlying these two broad dimensions should be considered as important potential targets to improve quality of life of this vulnerable population., (Copyright © 2019.

Background: Few studies have examined the prevalence and correlates of subsyndromal and syndromal depressive symptoms (SSSD) among older adults with schizophrenia spectrum disorder. In this report, we examined the prevalence of SSSD and their associations with sociodemographic characteristics, clinical characteristics of schizophrenia, comorbidity, psychotropic medications, quality of life, functioning and mental health care utilization in a large, multicenter sample of older adults with schizophrenia spectrum disorder., Methods: Data from the Cohort of individuals with Schizophrenia Aged 55 years or more (CSA) were used to examine the prevalence of SSSD, defined using the Center of Epidemiologic Studies Depression (CESD) scale. Clinical characteristics associated with SSSD were explored., Results: Among 343 older adults with schizophrenia spectrum disorder, 78.1% had either subsyndromal (30.6%) or syndromal (47.5%) depressive symptoms. SSSD were independently associated with positive and negative symptoms, lower quality of life, non-late-onset psychosis, benzodiazepine use and urbanicity. There were no significant associations of SSSD with other sociodemographic characteristics and psychotropic medications, or with general medical conditions. We found no significant differences in the proportion of participants who were treated with antidepressants between those with syndromal depressive symptoms and those without depression (22.1% vs. 20.0%, p = 0.89). SSSD were not associated with higher mental health care utilization., Limitations: Data were cross-sectional and depression was not evaluated with a semi-structured interview., Conclusion: SSSD may be highly prevalent and under-assessed and/or undertreated among older adults with schizophrenia spectrum disorder. Our findings should alert clinicians about the need to assess systematically and regularly depression in this vulnerable population., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Metabolic syndrome and its associated morbidity and mortality have been well documented in adults with schizophrenia. However, data is lacking for their geriatric counterparts. We sought to investigate the frequency of screening and the prevalence of metabolic syndrome in older adults with schizophrenia, as well as its possible correlates, using the Cohort of individuals with schizophrenia Aged 55 years or more study (n = 353). We found that 42.2% (n = 149) of our sample was screened for metabolic syndrome. Almost half of those (n = 77; 51.7%) screened positive according to ATPIII criteria. Hypertension and abdominal obesity were the two most prevalent metabolic abnormalities. Screening was positively associated with male gender and urbanicity, and metabolic syndrome diagnosis was positively associated with cardiovascular disorders and consultation with a general practitioner (all p < 0.05). However, there were no significant associations of metabolic syndrome with socio-demographic or clinical characteristics, psychotropic medications, other medical conditions and other indicators of mental health care utilization. Our findings support that the prevalence of metabolic syndrome among older adults with schizophrenia spectrum disorder is high and screening is crucial mainly in those patients with hypertension and/or abdominal obesity. Factors at play might be different than those in the younger population., (Copyright © 2019. Published by Elsevier B.V.)

Background: Medial prefrontal cortex (MPFC) activity during self-referential processing has been associated with rumination and found aberrant in depression. We investigated whether this aberrant activity reflects a trait marker that persists in remitted patients., Methods: Twenty-five patients fully remitted from major depression for at least 6 months, and 29 matched healthy controls were scanned with fMRI while presented with personality trait words in two conditions: Self condition asked whether the trait described themselves; General condition asked whether the trait was generally desirable. Contrasts-of-interest were examined in a factorial model and rumination correlates were examined in 2-sample t-tests with Ruminative Response Style score as covariate. All findings were reported at a conservative p < 0.05, with whole-brain peak-level family-wise error correction., Results: Self-referential processing increased anterior cortical midline activity to a similar extent in both groups. Dorsal anterior cingulate cortex (MNI(x,y,z) = -12,20,26) and dorsal MPFC (MNI(x,y,z) = -6,46,40) activity during self-referential processing was positively associated with rumination in healthy control subjects and negatively associated with rumination in remitted patients., Limitations: A longitudinal design tracking the relationship between rumination and MPFC activity would have aided the interpretation of our findings as to whether high ruminators are exhibiting an adaptive process to maintain remission or whether it represents a maladaptive process considering that high ruminators have an increased vulnerability for relapse., Conclusions: The association between increased anterior cortical midline activity during self-referential processing and rumination differentiated healthy controls from formerly depressed patients. Self-referential neural processing during remission from depression may depend on the cognitive tendencies to ruminate., (Copyright © 2019. Published by Elsevier B.V.)

Background: The association between depression and the metabolic syndrome remains poorly understood. Diet and physical activity may partly explain this association., Methods: Baseline data on 64,861 subjects from the French population-based Constances cohort was analyzed. Depressive symptoms were determined with the Center of Epidemiologic Studies Depression (CES-D) scale. A CES-D score ≥ 19 combined with self-reported limitations related to depressive symptoms was used to define depression. The metabolic syndrome was defined according to the International Diabetes Federation criteria. Dietary patterns were determined with a food frequency questionnaire and a principal component analysis. Physical activity was measured with 3 questions resulting in a composite 6-point scale. Associations between depression and the metabolic syndrome were estimated through logistic regression and path analysis., Results: The odds-ratios (95% confidence interval) for the association between depression and the metabolic syndrome, adjusting for age, sex, education and income, was 1.75 (1.57-1.96). The path analysis showed that 23% of this association was explained by diet and physical activity, 67% being attributed to physical activity., Limitations: The cross-sectional nature of the analyses warrants the results to be confirmed by longitudinal analyses., Conclusion: Diet and physical activity might partially explain the association between depressive symptoms and metabolic syndrome but other factors (e.g. inflammatory factors) are involved., (Copyright © 2018 Elsevier B.V.

The limited published literature on the subject suggests that there may be differences in how females and males experience narcissistic personality disorder (NPD) symptoms. The aim of this study was to use methods based on item response theory to examine whether, when equating for levels of NPD symptom severity, there are sex differences in the likelihood of reporting DSM-IV-TR NPD symptoms. We conducted these analyses using a large, nationally representative sample from the USA (n=34,653), the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). There were statistically and clinically significant sex differences for 2 out of the 9 DSM-IV-TR NPD symptoms. We found that males were more likely to endorse the item 'lack of empathy' at lower levels of narcissistic personality disorder severity than females. The item 'being envious' was a better indicator of NPD severity in males than in females. There were no clinically significant sex differences on the remaining NPD symptoms. Overall, our findings indicate substantial sex differences in narcissistic personality disorder symptom expression. Although our results may reflect sex-bias in diagnostic criteria, they are consistent with recent views suggesting that narcissistic personality disorder may be underpinned by shared and sex-specific mechanisms., (Copyright © 2017 Elsevier B.V.

Objectives: To examine (i) the frequency of different sleep complaints (early wake-up, trouble falling asleep, hypersomnia) and their co-occurrence and (ii) the sociodemographic characteristics and psychiatric comorbidity associated with each type of sleep profiles., Methods: Data were drawn from the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative survey of the US adult population (wave 1, 2001-2002; wave 2, 2004-2005). The primary analyses were limited to 3573 participants who had a DSM-IV-TR diagnosis of major depressive episode (MDE) between the two waves. We used a multiple regression model to estimate the strength of independent associations between self-reported sleep complaints, sociodemographic characteristics and lifetime psychiatric comorbidity., Results: Most of participants with MDE (92%) reported significant sleep complaints, from whom 85.2% had insomnia and 47.5% hypersomnia symptoms. The prevalence rates were for insomnia "only" of 48.5%, hypersomnia "only" of 13.7%, and their co-occurrence of 30.2%. We found that several sociodemographic characteristics (gender, age, education, individual and familial income, marital status) and psychiatric disorders (bipolar disorders, post-traumatic disorders and panic disorder) were significantly and independently associated with different sleep profiles. The co-occurrence of insomnia (especially early wake-up) and hypersomnia presented with a two-/three- fold increase risk of bipolar disorders., Limitations: Definitions of sleep complaints were qualitative and subjective., Conclusion: Sleep complaints are prevalent and heterogeneous in expression during MDE. Sleep disturbance profiles are associated with specific patterns of comorbidity. Our findings highlight the importance of continued research on sleep complaints during MDE while taking into account psychiatric comorbidity., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Background: The inclusion of subsyndromal forms of bipolarity in the fifth edition of the DSM has major implications for the way in which we approach the diagnosis of individuals with depressive symptoms. The aim of the present study was to use methods based on item response theory (IRT) to examine whether, when equating for levels of depression severity, there are differences in the likelihood of reporting DSM-IV symptoms of major depressive episode (MDE) between subjects with and without a lifetime history of manic symptoms., Methods: We conducted these analyses using a large, nationally representative sample from the USA (n=34,653), the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions., Results: The items sadness, appetite disturbance and psychomotor symptoms were better indicators of depression severity in participants without a lifetime history of manic symptoms, in a clinically meaningful way. DSM-IV symptoms of MDE were substantially less informative in participants with a lifetime history of manic symptoms than in those without such history., Limitations: Clinical information on DSM-IV depressive and manic symptoms was based on retrospective self-report, Conclusions: The clinical presentation of depressive symptoms may substantially differ in individuals with and without a lifetime history of manic symptoms. These findings alert to the possibility of atypical symptomatic presentations among individuals with co-occurring symptoms or disorders and highlight the importance of continued research into specific pathophysiology differentiating unipolar and bipolar depression., (Copyright © 2016 Elsevier B.V.

Background: Whether there are systematic sex differences in posttraumatic stress disorder (PTSD) symptom expression remains debated. Using methods based on item response theory (IRT), we aimed at examining differences in the likelihood of reporting DSM-IV symptoms of PTSD between women and men, while stratifying for major trauma type and equating for PTSD severity., Method: We compared data from women and men in a large nationally representative adult sample, the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses were conducted in the full population sample of individuals who met the DSM-IV criterion A (n=23,860) and in subsamples according to trauma types., Results: The clinical presentation of the 17 DSM-IV PTSD symptoms in the general population did not substantially differ in women and men in the full population and by trauma type after equating for levels of PTSD severity. The only exception was the symptom "foreshortened future", which was more likely endorsed by men at equivalent levels of PTSD severity., Limitations: The retrospective nature of the assessment of PTSD symptoms could have led to recall bias. Our sample size was too small to draw conclusions among individuals who experienced war-related traumas., Conclusions: Our findings suggest that the clinical presentation of PTSD does not differ substantially between women and men. We also provide additional psychometric support to the exclusion of the symptom "foreshortened future" from the diagnostic criteria for PTSD in the DSM-5., (Copyright © 2015 Elsevier B.V.

Childhood-onset compared to adulthood-onset of major depression is associated with increased rates of serious cardiovascular events, independently of cardiovascular risk factors. This could be explained by a longer duration of exposure to depression. Cardiovascular disease risk should be systematically assessed in individuals with long duration of major depression., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

Background: The explanation of the lower lifetime prevalence rate of major depressive disorder (MDD) in older adults compared to younger people in community surveys is debated. This study examines the hypothesis that the decrease of the lifetime prevalence of MDD in older adults may be due to an age-related difference in the lifetime prevalence of subthreshold hypomania and, to a lesser extent, to the increased rate of medical induced-depression., Methods: Data were derived from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a national representative sample of 43,093 adults of the United States population. We examined lifetime prevalence rates of pure MDD and MDD plus subthreshold hypomania (D(m)) by age, assuming that the lifetime prevalence of pure MDD in older adults would be similar to that in the youngest cohort, consequent to an inverse age-D(m) relationship. We further considered non-hierarchical MDD (i.e., general medical condition depressive disorders were not ruled out) with the same method., Results: The lifetime prevalence of D(m) among depressed adults aged 65 years and over was substantially lower compared to the youngest group. When considering non-hierarchical MDD, the odds ratio of the lifetime prevalence estimates of non-hierarchical pure MDD in older adults compared to the youngest group appeared not significantly different from 1., Conclusions: Findings indicate that the decrease of lifetime prevalence of MDD in older adults may be due to an age-related difference in the lifetime prevalence of subthreshold hypomania and, to a lesser extent, to the increased rate of medical induced-depression., (Copyright © 2013 Elsevier B.V.

Background: Research on the generalizability of clinical trials in panic disorder is limited. The present study sought to quantify the generalizability of clinical trials' results of individuals with DSM-IV panic disorder (PD) to a large community sample., Methods: Data were derived from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a large national representative sample of 43,093 adults of the United States population. We applied a standard set of eligibility criteria representative of PD clinical trials to all adults with past 12 months PD (n=907), and then to a subgroup of participants seeking treatment (n=105). Our aim was to determine the proportion of participants with PD who would have been excluded by typical eligibility criteria., Results: We found that more than 8 out of ten participants (80.52%; 95% CI=77.13-83.52%) with PD were excluded by at least one criterion. In the subgroup of participants who sought treatment, the exclusion rate by at least one criterion was higher (92.40%; 95% CI=84.60-96.42%). For the full sample and the treatment-seeking subsample, having currently a depression and a diagnosis of alcohol or drug abuse/dependence were the criteria excluding the highest percentage of participants. Having a lifetime history of bipolar disorder and a current significant medical condition also excluded a substantial proportion of individuals in both samples. Exclusion rates were similar when considering panic disorder with and without agoraphobia., Conclusions: Clinical trials, that exclude a majority of adults with panic disorder, should carefully consider the impact of eligibility criteria on the generalizability of their results. As required by CONSORT guidelines, reporting exclusion rate estimate and reasons of eligibility should be mandatory in both clinical trials and meta-analyses., (Copyright © 2012 Elsevier B.V.

This study presents gender effects in sociodemographics and psychiatric correlates of bullying in the United States. Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of U.S. adults. Face-to-face interviews of more than 43,000 adults were conducted during the 2001-2002 period. The present study compared 2460 respondents who ever bullied with 39,501 respondents who did not, stratified by gender. The prevalence of this behavior in the U.S. was significantly higher in men (8.5%) than in women (4.2%). Multivariate logistic regression analyses indicated strong associations in both genders with numerous psychiatric and addictive disorders with significant gender effects. Following adjustments for sociodemographic characteristics and other antisocial behaviors, women who ever bullied were significantly more likely to have any lifetime externalizing, including conduct disorder, as well as any lifetime internalizing spectrum disorder compared to men with such behavior. Bullying in women may be a symptom of a broader syndrome than in men, including more prevalent impairment of impulse control and more frequent affective disorders., (Copyright © 2012 Elsevier Ireland Ltd.

This study presents gender differences in sociodemographics and in psychiatric correlates of firesetting in the United States. Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a representative sample of U.S. adults. Face-to-face interviews of more than 43,000 adults were conducted in the 2001-2002 period. This study focused on the 407 subjects with a lifetime history of firesetting. The prevalence of lifetime firesetting in the U.S. was 1.7% in men and 0.4% in women. Firesetting was significantly associated with a wide range of antisocial behaviors that differed by gender. Multivariate logistic regression analyses indicated associations in both genders with psychiatric and addictive disorders. Men with a lifetime history of firesetting were significantly more likely than men without such history to have lifetime generalized anxiety disorder as well as a diagnosis of conduct disorder, antisocial personality disorder, alcohol or cannabis use disorder, and obsessive-compulsive personality disorder. Women with a lifetime history of firesetting were significantly more likely than women without such history to have lifetime alcohol or cannabis use disorder, conduct disorder, and antisocial or obsessive compulsive personality disorder, as well as psychotic disorder, bipolar disorder or schizoid personality disorder. Women with a lifetime history of firesetting were significantly more likely than men with such history to have a lifetime diagnosis of alcohol abuse and antisocial personality disorder as well as a diagnosis of schizoid personality disorder. Our findings indicate that firesetting in women could represent a behavioral manifestation of a broader spectrum than firesetting in men., (Copyright © 2011 Elsevier Ltd. All rights reserved.)
