RESUMO
The objective was to evaluate the risk of presenting an alcohol use disorder (AUD) in outpatient psychiatric units and compare it with drug addiction outpatient units and with healthy controls in the same administrative health area. An observational, descriptive, multicenter study was carried out in which a total of 1054 participants were evaluated. Data were obtained by means of the camouflaged CAGE questionnaire, which consists of 4 basic questions camouflaged with 8 other questions about healthy lifestyle habits. Cut-off points 1 and 2 were considered.Of the total number of participants, 588 were psychiatric outpatients, 153 outpatients from addiction centers and 313 healthy individuals. The mean age of the total sample was 45.8 years and the percentage of men was 53.2%. Of the total sample, 38.3% scored ≥1, as did 34.2% of psychiatric patients, 72.5% of drug addicts and 29.4% of healthy people. The ≥2 cut-off was reached by 26.6% of the total sample, 22.6% of psychiatric patients, 64.7% of drug addicts and 15.3% of healthy subjects. The participants with the highest percentage of ≥1 scores were men (48.8%), those younger than 30 years (50%), those with a diagnosis of alcohol use disorder (95.9%) and ADHD (83.3%).Psychiatric patients are at a higher risk of having an AUD than the healthy subjects, although lower than those who are drug addicts, and the CAGE questionnaire is a simple and useful tool to detect the risk patients have to suffer the condition under study.
El objetivo fue evaluar el riesgo de presentar un trastorno por uso de alcohol (TUA) en las consultas psiquiátricas ambulatorias y compararlo con las consultas de drogodependencias y con individuos sanos de la misma zona de salud. Se realizó un estudio observacional, descriptivo, multicéntrico, en el que fueron incluidos un total de 1054 participantes. Se utilizó el cuestionario CAGE camuflado para la obtención de los datos, que consta de 4 preguntas básicas camufladas con otras 8 preguntas sobre hábitos de vida saludables. Se consideraron los puntos de corte de 1 y 2.Del total de participantes, 588 eran pacientes psiquiátricos ambulatorios, 153 de los centros de drogodependencias ambulatorios y 313 sanos. La edad media de la muestra fue de 45,8 años y el porcentaje de hombres fue del 53,2%. El 38,3% de los participantes presentaron una puntuación ≥1, el 34,2% en las consultas psiquiátricas, el 72,5% en las de drogodependencias y el 29,4% en sanos. El 26,6% presentaron una puntuación ≥2, el 22,6% en las consultas psiquiátricas, el 64,7% en las de drogodependencias y el 15,3% en sanos. Los que presentaron mayor porcentaje de puntuación ≥1 fueron los hombres (48,8%), los menores de 30 años (50%), y los que tenían un diagnóstico de trastorno por uso de alcohol (95,9%) y de TDAH (83,3%).Los pacientes psiquiátricos presentan un mayor riesgo de presentar un TUA que los individuos sanos, aunque menor que los drogodependientes, siendo el cuestionario CAGE una herramienta sencilla y útil para detectar el riesgo de presentarlos.

BACKGROUND: In addition to factors intrinsic to bipolar disorder (BD), sexual functioning (SF) can be affected by extrinsic causes, such as psychotropic drugs. However, the effect of mood stabilizers on SF and quality of life (QoL) is an underexplored research area. AIM: To analyze SF in BD outpatients in euthymia for at least 6 months treated only with mood stabilizers and the association between SF and QoL. METHODS: A multicenter cross-sectional study was conducted in 114 BD outpatients treated with (i) lithium alone (L group); (ii) anticonvulsants alone (valproate or lamotrigine; A group); (iii) lithium plus anticonvulsants (L+A group); or (iv) lithium plus benzodiazepines (L+B group). The Changes in Sexual Functioning Questionnaire Short Form (CSFQ-14) was used. Statistical analyses were performed to compare CSFQ-14 scores among the pharmacological groups. An adaptive lasso was used to identify potential confounding variables, and linear regression models were used to study the association of the CSFQ-14 with QoL. MAIN OUTCOME MEASURES: Self-reports on phases of the sexual response cycle (ie, desire, arousal, and orgasm) and QoL were assessed. RESULTS: The A group had better total SF scores than the L group and the L+B group. Relative to the A group, the L and L+B groups had worse sexual desire; the L group had worse sexual arousal; and the L+A group and the L+B group had worse sexual orgasm. Regarding sociodemographic factors, being female and older age were associated with worse total SF and all subscale scores. Among all subscales scores, higher sexual arousal scores were associated with better QoL. CLINICAL IMPLICATIONS: Potential modified extrinsic factors such as psychotropic medication that can affect SF can be addressed and adjusted to lessen side effects on SF. STRENGTHS & LIMITATIONS: Sample of patients with euthymic BD in treatment with mood stabilizers and no antipsychotics or antidepressants, substance use as an exclusion criterion, and use of a validated, gender-specific scale to evaluate SF. Major limitations were cross-sectional design, sample size, and lack of information about stability of relationship with partner. CONCLUSIONS: Lithium in monotherapy or in combination with benzodiazepines is related to worse total SF and worse sexual desire than anticonvulsants in monotherapy. While the addition of benzodiazepines or anticonvulsants to lithium negatively affects sexual orgasm, sexual arousal (which plays a significant role in QoL) improves when benzodiazepines are added to lithium. Anticonvulsants in monotherapy have the least negative effects on SF in patients with BD. García-Blanco A, García-Portilla MP, Fuente-Tomás L de la, et al.

Alcohol use disorders (AUD) are 2 times higher among psychiatric patients than in the general population. The under-recognition of this dual diagnosis can entail several negative outcomes. Early assessment with a screening tool like the CAGE questionnaire could be an opportunity to improve patients' prognoses. The objective of this study is to assess AUD risk in an outpatient psychiatric sample with a modified CAGE, considering the influence of age, gender and clinical psychiatric diagnosis. An observational, multicentric, descriptive study was carried out. The 4-item CAGE scale, camouflaged in a healthy lifestyle questionnaire, was implemented, using a cut-off point of one. 559 outpatients were assessed. 54% were female and the average age was 50.07 years. 182 patients presented a CAGE score ≥1 (45.1% of men and 21.9% of women). Gender was the strongest predictor of a positive result in CAGE, as men were 3.03 times more likely to score ≥1 on the CAGE questionnaire (p < .001, 95% CI: 0.22-0.49). Patients with bipolar and personality disorders had the highest rates of CAGE scores ≥1 (45.2 and 44.9%, respectively), with a significant association between diagnosis and a positive score (p = .002). Patients above 60 years were 2.5 times less likely to score ≥1 on the CAGE (p = .017, 95% CI: 0.19-0.85). Specific screening questionnaires, like the CAGE scale, can be an easy and useful tool in the assessment of AUD risk in psychiatric outpatients. Male patients with a bipolar or personality disorder present a higher risk of AUD.
Los trastornos por uso de alcohol (TUA) son 2 veces más frecuentes en pacientes psiquiátricos que en la población general. El infradiagnóstico de patología dual puede tener diversas consecuencias negativas; una valoración precoz con herramientas de cribaje como la escala CAGE podría mejorar el pronóstico de estos pacientes. El objetivo de este estudio es valorar el riesgo de TUA en pacientes psiquiátricos ambulatorios con una CAGE modificada, considerando la influencia de edad, género, y diagnóstico psiquiátrico. Se realizó un estudio descriptivo observacional, multicéntrico. La escala CAGE de 4 ítems, camuflada en un cuestionario de vida saludable, se aplicó utilizando el punto de corte de 1. Se valoraron 559 pacientes. El 54% eran mujeres, y la edad media fue de 50,07 años. 182 pacientes presentaron una puntuación ≥1 (45,1% de los hombres y 21,9% de las mujeres). El género fue el predictor principal de un resultado positivo en la escala CAGE, siendo 3,03 veces más probable que los hombres obtengan una puntuación ≥1 (p < ,001, 95% IC: 0,22-0,49). El trastorno bipolar y los trastornos de personalidad presentaron las tasas más altas de puntuaciones ≥1 (45,2 y 44,9%, respectivamente) con una asociación significativa entre diagnóstico y un resultado positivo (p = ,002). Los pacientes de más de 60 años mostraron 2,5 veces menos probabilidades de obtener una puntuación positiva (p = ,017, 95% IC: 0,19-0,85). Cuestionarios específicos, como CAGE, pueden ser herramientas sencillas y útiles para valorar el riesgo de TUA en pacientes psiquiátricos ambulatorios. Los pacientes hombres con trastorno bipolar o de personalidad presentan un riesgo más elevado de TUA.

Impaired intestinal permeability has recently been suggested as a possible source of chronic inflammation in schizophrenia, but its association with specific psychopathological features remains uncertain. This study aimed to explore the interaction between intestinal permeability, inflammation, and positive and negative symptoms in schizophrenia using a network analysis approach. The study sample comprised 281 adults with schizophrenia (age 40.29 ± 13.65 years, 63.0 % males), enrolled in a cross-sectional observational study assessing intestinal permeability. We estimated the network with a Gaussian graphical model, incorporating scores from 14 individual items of the Positive and Negative Syndrome Scale (PANSS), along with body mass index (BMI), and plasma C-reactive protein (CRP) and lipopolysaccharide-binding protein (LBP) levels. We calculated strength centrality and expected influence and used bridge centrality statistics to identify the bridge nodes. Distinct but highly interconnected clusters emerged for positive and negative symptoms. The biological variables were closely associated with each other. LBP was positively linked with CRP and BMI, but only indirectly connected to psychopathology. CRP exhibited direct positive relationships with various PANSS items and bridged LBP and BMI with psychopathology. Bridge nodes included Conceptual Disorganisation (P2), Active Social Avoidance (G16), Suspiciousness/Persecution (P6), and CRP. These findings support the role of gut-derived inflammation as a mechanism underlying greater symptom severity in schizophrenia and emphasise the importance of addressing dietary habits not only to enhance physical health but also to contribute to improving psychotic symptoms.

INTRODUCTION: Although there is evidence that higher cognitive reserve (CR) is a protective factor and it has been related to better prognosis, there have been no studies to date that have explored the CR level and its impact in clinical, neurocognitive and lifestyle outcomes according to the stage of the disease: early stage of psychosis (ESP) or chronic schizophrenia (SCZ). MATERIAL AND METHODS: A total of 60 patients in the ESP and 225 patients with SCZ were enrolled in the study. To test the predictive capacity of CR for each diagnostic group, a logistic regression analysis was conducted. Hierarchical linear regression analyses were performed to explore the associations between CR and different outcomes. The mediation analyses were performed according to the principles of Baron and Kenny. RESULTS: Patients with SCZ showed lower CR than those in the ESP (p<0.001). CR correctly classified 79.6% of the cases (p<0.001; Exp(B)=1.062). In ESP group, CR was related to working memory (p=0.030) and negative symptoms (p=0.027). CR (t=3.925, p<0.001) and cannabis use (t=2.023, p=0.048) explained 26.7% of the variance on functioning (p=0.003). In patients with SCZ, CR predicted all cognitive domains, negative symptoms (R2=0.091, p=0.001) and functioning (R2=0.074, p=0.005). In both ESP and SCZ groups, higher CR was associated with lower body mass index and circumference. In ESP group, the effect of adherence to Mediterranean diet on functioning (p=0.037) was mediated by CR level (p=0.003). CONCLUSIONS: The implications of CR depend on the stage of the disease (ESP vs. SCZ), with a greater effect on neurocognition and negative symptoms in patients with chronic SCZ.
RESUMO
BACKGROUND: Altered intestinal permeability and low-grade chronic inflammation disrupt the integrity of the blood-brain barrier (microbiota-gut-brain axis), probably playing a role in the pathophysiology of schizophrenia-spectrum disorders. However, studies assessing the microbiota-gut-brain axis are inconsistent. This article describes the rationale, objectives, protocol, and presents descriptive results for a new project. METHODS: The sample of this study came from an observational, cross-sectional and multisite study including four centers in Spain (PI17/00246) recruiting adult patients with DSM-5 schizophrenia-spectrum disorders at any stage of the disease. The aims of the project are to assess the interrelation between intestinal permeability and low-grade chronic inflammation in schizophrenia-spectrum disorders and the role of peripheral biomarkers, diet, exercise, metabolic syndrome, disease severity and functioning as well as cognition. Assessments included the following variables: (1) anthropometric, (2) intestinal permeability, diet, and physical exercise, (3) clinical and functional, (4) neuropsychological and cognitive reserve, and (5) peripheral biomarkers from blood. RESULTS: A total of 646 patients were enrolled (257, 39.7% female). Mean age was 43.2±13.6 years, illness duration 15.1±11.5 years. 55.8% consumed tobacco. Positive PANSS score was 13.68±6.55, and 20.38±8.69 in the negative symptoms. CGI was 4.16±2.22 and GAF was 60.00±14.84. CONCLUSION: The results obtained by this project are expected to contribute toward the understanding of the physiopathology of schizophrenia-spectrum disorders. This will likely aid to personalize treatments in real-world clinical practice, potentially including variables related to intestinal permeability and inflammation.
RESUMO
INTRODUCTION: Bipolar disorder (BD) has been reconceptualised as a progressive disorder that develops from mild to severe presentations. An empirical staging model - the Empirically Developed Clinical Staging Model for BD (EmDe-5) - was developed in a previous study. This study aims to further validate that model using a larger and more representative Spanish sample. MATERIAL AND METHODS: 183 BD outpatients were recruited at 11 sites in Spain. Assessment included clinical characteristics of the BD (number of hospitalisations, number of suicide attempts, comorbid personality disorders), physical health (BMI, metabolic syndrome, number of physical illnesses), cognition (SCIP), functioning (permanently disabled due to BD, FAST), and quality of life (SF-36). The CGI-S, VAS-S, and psychopharmacological treatment pattern were used as external validators. RESULTS: Ten patients (51.5%) were classified as stage 1, 33 (18%) as stage 2, 93 (508%) as stage 3, 37 (202%) as stage 4, and 10 (55%) as stage 5. All profilers, other than number of suicide attempts (p=0.311) and comorbid personality disorder (p=0.061), exhibited worse scores from stage 1 to 5. As expected, VAS-S and CGI-S scores were worse in the later stages. Regarding treatment, early stages (1-2) were associated with the use of one to three drugs while late stages (4-5) were associated with four or more drugs (p=0.002). CONCLUSIONS: We confirm the EmDe-5 staging model's construct validity. The ease of obtaining the profilers, together with the operational criteria provided to quantify them, will facilitate the use of the EmDe-5 staging model in daily clinical practice.
RESUMO
Sexual functioning in bipolar disorder (BD) is dependent on multiple clinical and demographic determinants that can eventually lead to sexual dysfunction. However, the contribution of affective temperaments remains unstudied in this population. In this cross-sectional multicentric work, we studied the impact of temperament traits on sexual functioning in 100 euthymic BD outpatients treated only with mood stabilizers with or without benzodiazepines. Temperament was evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - Autoquestionnaire (TEMPS-A) and sexual functioning with the Changes on Sexual Functioning Questionnaire (CSFQ-14). The effect of temperament on sexual functioning was analyzed using Bayesian ordinal regression models, which included age, gender, BD type, dominant polarity, metabolic syndrome, marital status, and affective symptomatology. Our results showed that hyperthymic traits predicted a significantly higher CSFQ-14 score for global sexual functioning (OR = 1.222; 95% CI [1.073, 1.431]), desire (OR = 1.164; 95% CI [1.025, 1.357]), arousal (OR = 1.278; 95% CI: [1.083, 1.551]), and orgasm (OR = 1.182; 95% CI [1.037, 1.365]). We did not find a significant contribution for other types of temperaments. Better sexual functioning was also associated with a better quality of life. Our findings highlight the importance of temperament traits in sexual functioning in euthymic BD, which may have implications in sexual dysfunction prevention.

OBJECTIVES: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and C-Reactive Protein (CRP) are markers of inflammation that are elevated in bipolar disorder (BD) and are also related to a higher risk of metabolic syndrome (MetS). This study aimed at investigating for the first time the association between NLR, PLR, and CRP and the metabolic status in BD. METHODS: We assessed the association between biomarkers and the metabolic status: number of metabolic risk factors, presence of MetS, insulin sensitivity (Quantitative Insulin Sensitivity Check Index, QUICKI) and insulin resistance (Homeostatic Model Assessment for Insulin Resistance, HOMA-IR index), in a sample of 219 outpatients with BD. RESULTS: 25.9% of the sample met the criteria for MetS. High levels of CRP were found in 12% of the sample. Older age, low PLR, high NLR, and high CRP levels significantly predicted a higher number of MetS risk factors (p < 0.001). Older age and low PLR were associated with a greater likelihood of developing MetS (p = 0.007). CONCLUSIONS: Although further studies are needed to replicate and validate these findings, inflammatory biomarkers as CRP, PLR and NLR could be useful tools to identify patients with a BD at risk for a metabolic adverse outcome.

Bipolar disorder (BD) has been identified as a life-course illness with different clinical manifestations from an at-risk to a late stage, supporting the assumption that it would benefit from a staging model. In a previous study, we used a clustering approach to stratify 224 patients with a diagnosis of BD into five clusters based on clinical characteristics, functioning, cognition, general health, and health-related quality of life. This study was design to test the construct validity of our previously developed k-means clustering model and to confirm its longitudinal validity over a span of 3 years. Of the 224 patients included at baseline who were used to develop our model, 129 (57.6%) reached the 3-year follow-up. All life domains except mental health-related quality of life (QoL) showed significant worsening in stages (p < 0.001), suggesting construct validity. Furthermore, as patients progressed through stages, functional decline (p < 0.001) and more complex treatment patterns (p = 0.002) were observed. As expected, at 3 years, the majority of patients remained at the same stage (49.6%), or progressed (20.9%) or regressed (23.3%) one stage. Furthermore, 85% of patients who stayed euthymic during that period remained at the same stage or regressed to previous stages, supporting its longitudinal validity. For that reason, this study provides evidence of the construct and longitudinal validity of an empirically developed, comprehensive staging model for patients with BD. Thus, it may help clinicians and researchers to better understand the disorder and, at the same time, to design more accurate and personalized treatment plans.

BACKGROUND: Cannabis use is markedly prevalent among patients with bipolar disorder (BD). However, to date, there have been no studies on this issue with a sex-based approach. This study examines if lifetime cannabis use (LCU) is differently associated with clinical course, functioning, and quality of life (QoL) in patients with BD by sex. METHODS: Secondary analysis of a cross-sectional, naturalistic, multicentre study. LCU was defined as having had at least one day of use per month for at least 12 consecutive months in a patient's life. RESULTS: A total of 224 patients with BD were included (65.2% women). Patients with LCU were younger (p = 0.001) and had their first hospitalization earlier (p<0.005) than those without LCU, regardless of sex. Among women, LCU was associated with being single (p = 0.006), worse sexual functioning (p = 0.006), financial functioning (p = 0.009), QoL [bodily pain (p = 0.009), vitality (p = 0.027), social functioning (p = 0.037), emotional role (p = 0.038), mental health (p = 0.001), and mental summary component (p = 0.012)]. After controlling for confounders, among women, LCU was associated with worse QoL, specifically on bodily pain (p = 0.049) and mental health (p = 0.016) subscales. Among males, no statistically significant differences were found between LCU and no LCU (NLCU) in any of the variables of the study. LIMITATIONS: This study was a secondary analysis not powered specifically to analyze cannabis use. CONCLUSIONS: LCU was associated with a younger age at first hospitalization in both women and men, while only women reported worse QoL on bodily pain and mental health subscales. Clinicians and public health providers should be aware of this and inform their patients and the general population of these detrimental effects.

There is a scarcity of studies assessing the influence of biomarkers in metabolic syndrome in psychiatric patients. Our aim was to correlate serum or plasma levels of 25-hydroxyvitamin D (25-OH-VD), retinol, vitamin B12 (VB12), folate and homocysteine (Hcy), with the metabolic status, in a sample of 289 outpatients with Schizophrenia or Bipolar Disorder. Logistic regression and multiple linear regressions were performed to assess the ability of biomarkers to predict the presence of MetS, the number of risk factors for MetS, and insulin resistance indexes (HOMA and QUICKI). Regarding the association between biomarkers and the QUICKI index, the model explained 6.8% of the variance, with folate and 25-OH-VD levels contributing significantly to the model. The model predicting the number of MetS risk factors was significant and explained 21.7% of the variance, being 25-OH-VD and retinol the statistically significant factors. As for the impact of biomarkers on MetS, the model was statistically significant, being 25-OH-VD and retinol levels the significant factors. We report for the first time an association between MetS and both low 25-OH-VD and high retinol concentrations. Inflammation-related biomarkers may help identify patients with a high risk of MetS who might benefit from healthy lifestyle counselling and early intervention.

INTRODUCTION: Bipolar disorder (BD) is a heterogeneous disorder needing personalized and shared decisions. We aimed to empirically develop a cluster-based classification that allocates patients according to their severity for helping clinicians in these processes. METHODS: Naturalistic, cross-sectional, multicenter study. We included 224 subjects with BD (DSM-IV-TR) under outpatient treatment from 4 sites in Spain. We obtained information on socio-demography, clinical course, psychopathology, cognition, functioning, vital signs, anthropometry and lab analysis. Statistical analysis: k-means clustering, comparisons of between-group variables, and expert criteria. RESULTS AND DISCUSSION: We obtained 12 profilers from 5 life domains that classified patients in five clusters. The profilers were: Number of hospitalizations and of suicide attempts, comorbid personality disorder, body mass index, metabolic syndrome, the number of comorbid physical illnesses, cognitive functioning, being permanently disabled due to BD, global and leisure time functioning, and patients' perception of their functioning and mental health. We obtained preliminary evidence on the construct validity of the classification: (1) all the profilers behaved correctly, significantly increasing in severity as the severity of the clusters increased, and (2) more severe clusters needed more complex pharmacological treatment. CONCLUSIONS: We propose a new, easy-to-use, cluster-based severity classification for BD that may help clinicians in the processes of personalized medicine and shared decision-making.

Clinical staging is a diagnostic tool used in other medical specialties, which has resulted from the combination of a categorical and dimensional approach. In the last 2decades, the usefulness of its application in the field of psychiatry has been suggested, mainly as a tool for diagnostic help, and therapeutic and prognostic orientation. In this paper we review the clinical staging models that have been proposed to date for bipolar disorder, depression and schizophrenia. A literature search was performed in PubMed and Medline databases. A total of 15 studies were selected according to inclusion and exclusion criteria. Models were grouped according to the type of disorder for which staging was proposed (bipolar disorder: 4, depression: 5, schizophrenia: 6), and their characteristics were described. As a conclusion, we identify the need to empirically validate these models to demonstrate that staging is a useful tool for clinical practice.

There is scarce knowledge about the impact of sleep disturbances on functioning and quality of life (QoL). This study aims to investigate the links between sleep satisfaction and duration, and functioning and QoL in euthymic BD patients. We made a secondary analysis of a cross-sectional, naturalistic, multicenter study. Inclusion criteria: DSM-IV BD diagnosis; ageâ¯>â¯17 years; written informed consent. Sample: 119 Spanish euthymic BD outpatients. Hierarchical multiple regressions were performed controlling for confounding factors. We found that almost half of the patients reported at least one sleep complaint, nighttime awakenings (60.5%) and difficulty falling asleep (31.9%) were the most frequent. Long sleep duration was associated with worse global functioning, and also with worse occupational functioning along with caffeine consumption. Sleep satisfaction was negatively associated with worse QoL in the mental health subscale and the summary mental. In both cases, the use of benzodiazepines negatively affects these QoL domains. In conclusion, euthymic bipolar patients frequently present sleep disturbances that seem to contribute to the impairment of their functioning and QoL. Also, the use of benzodiazepines negatively affects the QoL of these patients. Thus, a detailed sleep evaluation should be performed, and the use of benzodiazepines should be reduced to the minimum.

BACKGROUND: Bipolar disorder (BD) is a disabling illness that is associated with low quality of life (QoL). This low QoL goes further than mood episodes, which suggests that stable traits, such as affective temperaments, can cause functional impairment. OBJECTIVE: Our study analyses the impact of affective temperaments on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of QoL in euthymic BD patients. METHODS: A multicentre study was conducted in 180 euthymic BD patients and 95 healthy controls. Firstly, statistical analyses were performed to compare QoL and affective temperaments between the two groups. Secondly, Adaptive Lasso Analysis was carried out to identify the potential confounding variables and select the affective temperaments as potential predictors on the PCS and MCS of QoL in BD patients, as well as the control group. RESULTS: QoL scores in terms of PCS and MCS in BD patients were significantly lower than in healthy individuals. Whereas anxious temperament, anxiety disorder comorbidity, and age were the best predictors of PCS impairment in BD patients, anxious temperament, subclinical depressive symptoms, and age were the best predictors of MCS impairment. LIMITATIONS: Further longitudinal studies with unaffected high-risk relatives are needed to examine the potential interaction between affective temperament and psychopathology. CONCLUSIONS: Anxious temperament has an impact on QoL in BD in terms of both the physical component and the mental component. Systematic screening of temperament in BD would give clinicians better knowledge of QoL predictors. Further research should allow more individualized treatment of BD patients based on temperamental factors.
