RESUMO

BACKGROUND: The Racing and Crowded Thoughts Questionnaire (RCTQ-13) is the most widely used specific scale for the measurement of racing thoughts, but there is currently no Spanish version that allow the evaluation in Spanish-speaking patients. The objective of this study is to translate, adapt, and validate the RCTQ-13 in a Colombian population with affective disorders. METHODS: The questionnaire was translated and back-translated, and corrections were implemented following a pilot test to improve comprehensibility. We included patients with Bipolar I Disorder and with Major depressive disorder seen in three centers in the city of Medellín, Colombia. We evaluate structural validity with confirmatory factor analysis, internal consistency, and test-retest reliability. Construct validity was also assessed with the comparison between euthymic, maniac, and depressive episodes and the correlation with worry, rumination, and mania scales. Responsiveness was measured 1 month after the first evaluation. Based on item response theory (IRT), we also estimated item difficulty, discrimination, and fit using a generalized partial credit model. RESULTS: Two hundred fifty subjects were included. Confirmatory factor analysis revealed that the three-factor structure of the scale was appropriate. Internal consistency was adequate for the entire scale (Cronbach's alpha = 0.95, 95% CI: 0.94-0.96) and for each factor. Test-retest reliability was good (intraclass correlation coefficient = 0.82, 95%IC: 0.70-0.88). For construct validity, we observed differences between patients with different types of affective episodes, a moderate positive correlation with the Penn State Worry Scale (r = 0.55) and the Ruminative Response Scale (r = 0.42), and a low negative correlation with the Young Mania Rating Scale (r = - 0.10). Responsiveness was proved to be adequate. Under IRT, the response thresholds for the response options are organized for all items. The infit was adequate for all items and the outfit was acceptable. CONCLUSIONS: The Spanish version of the RCTQ-13 is a reliable, valid, and responsive scale and can be used for the clinical assessment of the construct of racing and crowded thoughts in patients with the spectrum of affective disorders in whom this experience can be expressed with different nuances. Further research is needed to expand the relationship with rumination and worry.

RESUMO

Objective: To contextualize a synthesis of evidence on interventions in student mental health during the COVID-19 pandemic through a deliberative dialogue with Ibero-American universities. Methods: An evidence synthesis and synchronous dialogues were previously conducted, consisting of subgroup discussions about the design and implementation of mental health interventions. An analysis of dialogic data was conducted, then organized by topic. Results: Fifty-seven representatives of 17 public and private Ibero-American universities participated in the meeting. In terms of the design of interventions, mental health is perceived as neglected, although its profile was raised by the pandemic. Interventions are guided by detection of needs; scientific evidence is rarely used to design them. Importance was given to forming an interdisciplinary team with continuous training in order to design a specific program that also covers families and teaching/administrative staff. In terms of implementation, problems include saturation of services due to high demand and lack of basic resources among students. Regarding the provision of resources, the influence of the broader context, including the institutional context, is undeniable. The dialogues were perceived as an opportunity to build a new set of interventions. Conclusions: These dialogues enriched the description of interventions already described in the literature on student mental health during the COVID-19 pandemic. However, implementing such interventions in the region means addressing previous neglect and a high level of unmet basic needs.


Objetivo: Contextualizar uma síntese de evidências sobre intervenções em saúde mental de estudantes universitários na pandemia de COVID-19, por meio do diálogo deliberativo com universidades ibero-americanas. Métodos: A partir de uma síntese de evidências previamente elaborada, o diálogo síncrono foi conduzido por meio de discussões em subgrupos sobre o planejamento e a implementação de intervenções em saúde mental. Os dados obtidos foram analisados e resumidos por área temática. Resultados: Cinquenta e sete integrantes de 17 universidades ibero-americanas públicas e privadas participaram do encontro. Os participantes indicaram que a saúde mental é negligenciada no planejamento das intervenções, mas ganhou visibilidade na pandemia. As intervenções são direcionadas às necessidades identificadas e raramente planejadas com base em evidências científicas. Disseram considerar importante formar uma equipe interdisciplinar com capacitação contínua para planejar um programa específico que englobe também familiares e o corpo docente e administrativo. Implementar intervenções é complicado porque os serviços estão sobrecarregados devido à grande demanda e à falta de recursos básicos para os estudantes. O contexto macro e institucional claramente influencia a disponibilização de recursos. O diálogo foi visto como uma oportunidade para consolidar um novo conjunto de intervenções. Conclusões: O presente diálogo contribuiu para enriquecer a literatura de intervenções de saúde mental para estudantes universitários na pandemia de COVID-19. Implementar intervenções no nosso contexto requer sanar as falhas por negligência passada e as enormes necessidades básicas não atendidas.

RESUMO

OBJECTIVE: Despite promising research and consensus recommendations on the important therapeutic role of physical therapy for motor functional neurological disorder (FND), little is known about the feasibility and potential efficacy of implementing physical therapy for this population in a U.S.-based outpatient program. Given health care system differences internationally, this is an important gap in the literature. METHODS: In this retrospective cohort study, the authors investigated the relationship between treatment adherence and clinical outcome in a hospital-based outpatient physical therapy clinical program. Medical records of 50 consecutive patients with motor FND referred from an FND clinical program were reviewed. The physical therapy intervention included a 1-hour initial assessment and the development of individualized treatment plans guided by published consensus recommendations. Statistical analyses included nonparametric, univariate screening tests followed by multivariate regression analyses. RESULTS: In univariate analyses, there was a statistically significant positive correlation between the number of sessions attended and clinical improvement. This relationship held when adjusting for demographic variables, concurrent psychogenic nonepileptic seizures, and other major neurological comorbidities. In a post hoc analysis of the subset of individuals with available gait speed data, posttreatment 10-meter gait speed times improved compared with baseline measurements. Baseline neuropsychiatric factors did not correlate with clinical improvement. CONCLUSIONS: This preliminary, retrospective cohort study demonstrated that treatment adherence to a U.S.-based outpatient physical therapy program was associated with clinical improvement. Prospective observational and randomized controlled trials are needed to further optimize physical therapy for patients with functional motor symptoms in the outpatient setting.

RESUMO

OBJECTIVE: Positive psychology interventions, which involve systematic completion of activities designed to promote well-being, are being increasingly studied in medically ill patients. However, the extent to which these interventions ameliorate patient anxiety remains unclear. Therefore, the aim of the study was to conduct a meta-analysis to determine the efficacy of positive psychology interventions in reducing anxiety in medical patients. METHODS: Electronic databases Medline, PsycINFO, SciELO, Cochrane (Central), and ClinicalTrials.gov were searched from inception to June 18, 2018, to identify studies of positive psychology interventions that included a validated measure of anxiety as an outcome measure. RESULTS: The search generated a total of 1024 studies. Twelve randomized controlled trials (n = 1131) delivered to medical patients were included in the review, and a further 11 nonrandomized trials (n = 300) were included in a secondary analysis. Positive psychology interventions were effective at reducing patient anxiety relative to a control with a small to medium effect size (g = -0.34, 95% confidence interval = -0.50 to -0.18), and results were maintained at a mean of 8-week follow-up (g = -0.31, 95% confidence interval = -0.54 to -0.08). Clinician-led interventions seemed to be more effective than self-administered interventions, and longer interventions were more effective than shorter interventions. Secondary analysis of nonrandomized trials also found that positive psychology interventions are associated with reduced anxiety. CONCLUSIONS: Positive psychology interventions seem to be effective at reducing medical patient anxiety. Future research is needed to determine optimal intervention characteristics, including dose and intervention content, that maximize the observed treatment effects.

RESUMO

OBJECTIVE: Some individuals with functional neurological disorder (FND) exhibit motor and affective disturbances, along with limbic hyper-reactivity and enhanced motor-limbic connectivity. Given that the multimodal integration network (insula, dorsal cingulate, temporoparietal junction (TPJ)) is implicated in convergent sensorimotor, affective and interoceptive processing, we hypothesised that patients with FND would exhibit altered motor and amygdalar resting-state propagation to this network. Patient-reported symptom severity and clinical outcome were also hypothesised to map onto multimodal integration areas. METHODS: Between-group differences in primary motor and amygdalar nuclei (laterobasal, centromedial) were examined using graph-theory stepwise functional connectivity (SFC) in 30 patients with motor FND compared with 30 healthy controls. Within-group analyses correlated functional propagation profiles with symptom severity and prospectively collected 6-month outcomes as measured by the Screening for Somatoform Symptoms Conversion Disorder subscale and Patient Health Questionnaire-15 composite score. Findings were clusterwise corrected for multiple comparisons. RESULTS: Compared with controls, patients with FND exhibited increased SFC from motor regions to the bilateral posterior insula, TPJ, middle cingulate cortex and putamen. From the right laterobasal amygdala, the FND cohort showed enhanced connectivity to the left anterior insula, periaqueductal grey and hypothalamus among other areas. In within-group analyses, symptom severity correlated with enhanced SFC from the left anterior insula to the right anterior insula and TPJ; increased SFC from the left centromedial amygdala to the right anterior insula correlated with clinical improvement. Within-group associations held controlling for depression, anxiety and antidepressant use. CONCLUSIONS: These neuroimaging findings suggest potential candidate neurocircuit pathways in the pathophysiology of FND.

RESUMO

Insecure attachment is a predisposing risk factor for the development of functional neurological disorder (FND). There is limited research investigating connections between attachment styles, other predisposing vulnerabilities, and symptom severity in patients with motor FND. By using a within-group design with prospective data collection, the authors performed univariate tests followed by multivariate linear regressions to investigate neuropsychiatric factors associated with four attachment styles (secure, fearful, preoccupied, and dismissing) among 56 patients with motor FND (mean age=40.2 years [SD=13.0]; women, N=41; men, N=15). In univariate analyses, fearful attachment style was associated with self-reported adverse life event burden, alexithymia, dissociation, depression, anxiety, impaired stress coping skills, functional neurologic symptom severity, and marital status. In a multivariate stepwise linear regression analysis, childhood abuse, alexithymia, depression, and not being married independently predicted fearful attachment. In a post hoc analysis, childhood sexual and emotional abuse were each independently associated with fearful attachment tendencies. There were no independent predictors of secure, preoccupied, or dismissing attachment styles in this study population. Future studies with larger cohorts are needed to investigate nuanced relationships among predisposing vulnerabilities for the development of FND, as well as potential links between risk factors, functional neurologic symptom severity, and clinical outcomes.

RESUMO

BACKGROUND: The relationships between baseline neuropsychiatric factors and clinical outcome in patients with functional neurological disorder (FND)/conversion disorder remain poorly understood. OBJECTIVE: This prospective, naturalistic pilot study investigated links between predisposing vulnerabilities (risk factors) and clinical outcome in patients with motor FND engaged in usual care within a subspecialty FND clinic. METHODS: Thirty-four patients with motor FND were enrolled and completed baseline and 6-month follow-up psychometric questionnaires. Univariate screening tests followed by multivariate linear regression analyses were used to investigate neuropsychiatric predictors of 6-month clinical outcome in patients with motor FND. RESULTS: In univariate analyses, baseline secure attachment traits and depression as measured by the Relationship Scales Questionnaire and Beck Depression Inventory-II positively correlated with improved Patient Health Questionnaire-15 scores. In a multivariate linear regression analysis adjusting for the interval time between baseline and follow-up data collection, baseline secure attachment and depression scores independently predicted improvements in Patient Health Questionnaire-15 scores. In additional analyses, patients with a diagnosis of psychogenic nonepileptic seizures compared to individuals with other motor FND subtypes showed a trend toward worse 6-month physical health outcomes as measured by the Short Form Health Survey-36. CONCLUSION: Future large-scale, multi-site longitudinal studies are needed to comprehensively investigate neuropsychiatric predictors of clinical outcome in patients with motor FND, including functional weakness, functional movement disorders, and psychogenic nonepileptic seizures.

RESUMO

Urokinase-type plasminogen activator (uPA) is a serine proteinase that, upon binding to its receptor (uPAR), catalyzes the conversion of plasminogen into plasmin on the cell surface. Our previous studies indicate that uPA and uPAR expression increase in the ischemic brain during the recovery phase from an acute ischemic injury and that uPA binding to uPAR promotes neurological recovery after an acute ischemic stroke. Here, we used male mice genetically deficient on either uPA (uPA-/-) or uPAR (uPAR-/-) or with a four-amino acid substitution into the growth factor domain of uPA that abrogates its binding to uPAR (PlatGFDhu/GFDhu) to investigate the mechanism whereby uPA promotes neurorepair in the ischemic brain. We found that neurons release uPA and astrocytes recruit uPAR to their plasma membrane during the recovery phase from a hypoxic injury and that binding of neuronal uPA to astrocytic uPAR induces astrocytic activation by a mechanism that does not require plasmin generation, but instead is mediated by extracellular signal-regulated kinase 1/2 (ERK1/2)-regulated phosphorylation of the signal transducer and activator of transcription 3 (STAT3). We report that uPA/uPAR binding is necessary and sufficient to induce astrocytic activation in the ischemic brain and that astrocytes activated by neuronal uPA promote synaptic recovery in neurons that have suffered an acute hypoxic injury via a mechanism mediated by astrocytic thrombospondin-1 (TSP1) and synaptic low-density lipoprotein receptor-related protein-1 (LRP1). In summary, we show that uPA/uPAR-induced astrocytic activation mediates a cross talk between astrocytes and injured neurons that promotes synaptic recovery in the ischemic brain.SIGNIFICANCE STATEMENT To date, there is no therapeutic strategy to promote synaptic recovery in the injured brain. Here, we show that neurons release urokinase-type plasminogen activator (uPA) and astrocytes recruit the uPA receptor (uPAR) to their plasma membrane during the recovery phase from a hypoxic injury. We found that binding of neuronal uPA to astrocytic uPAR promotes astrocytic activation and that astrocytes activated by uPA-uPAR binding promote synaptic recovery in neurons that have suffered a hypoxic injury by a mechanism that does not require plasmin generation, but instead is mediated by ERK1/2-regulated STAT3 phosphorylation, astrocytic thrombospondin-1 (TSP1) and synaptic low-density lipoprotein receptor-related protein-1 (LRP1). Our work unveils a new biological function for uPA-uPAR as mediator of a neuron-astrocyte cross talk that promotes synaptic recovery in the ischemic brain.

RESUMO

BACKGROUND: Catatonia is a challenging and heterogeneous neuropsychiatric syndrome of motor, affective and behavioral dysregulation which has been associated with multiple disorders such as structural brain lesions, systemic diseases, and psychiatric disorders. This systematic review summarized and compared functional neuroimaging abnormalities in catatonia associated with psychiatric and medical conditions. METHODS: Using PRISMA methods, we completed a systematic review of 6 databases from inception to February 7th, 2024 of patients with catatonia that had functional neuroimaging performed. RESULTS: A total of 309 studies were identified through the systematic search and 62 met the criteria for full-text review. A total of 15 studies reported patients with catatonia associated with a psychiatric disorder (n = 241) and one study reported catatonia associated with another medical condition, involving patients with N-methyl-d-aspartate receptor antibody encephalitis (n = 23). Findings varied across disorders, with hyperactivity observed in areas like the prefrontal cortex (PFC), the supplementary motor area (SMA) and the ventral pre-motor cortex in acute catatonia associated to a psychiatric disorder, hypoactivity in PFC, the parietal cortex, and the SMA in catatonia associated to a medical condition, and mixed metabolic activity in the study on catatonia linked to a medical condition. CONCLUSION: Findings support the theory of dysfunction in cortico-striatal-thalamic, cortico-cerebellar, anterior cingulate-medial orbitofrontal, and lateral orbitofrontal networks in catatonia. However, the majority of the literature focuses on schizophrenia spectrum disorders, leaving the pathophysiologic characteristics of catatonia in other disorders less understood. This review highlights the need for further research to elucidate the pathophysiology of catatonia across various disorders.

RESUMO

Introduction: Adjustment disorder (AD) is a diagnosis that must be differentiated from major depressive episode (MDE) because of the therapeutic implications. The aim of this study is to understand the experience of patients who in their lifetime have been diagnosed with AD as well as MDE to establish the characteristics of each disorder. Methods: A descriptive phenomenological approach was used with in-depth interviews to four patients and the method proposed by Colaizzi to understand the experiences and reach the description of both disorders. Results: Three women and one man, with advanced schooling were interviewed. The participants emphasized the existence of differences that were grouped in: the attribution made by the individual, the theme of cognitions, the variability in the course, the possibility of mood modulation, the syndrome severity, the presence of hopelessness and the perceived course. Conclusion: Phenomenological differences were found in the subjective experience of MDE and AD. The MDE would be described as an intense state of generalized shutdown of the subject's own life, with little response to events, and the AD, as a dynamic reaction attributed to a stressful event, with high variability in the course of symptoms due to the dependence on such event, with the preserved hope that it will end.

RESUMO

INTRODUCTION: Attention deficit/hyperactivity disorder (ADHD) has genetic and environmental aetiological factors. There are few publications on the environmental factors. The objective of this review is to present the role of psychosocial adversity in the aetiology and course of ADHD. METHODS: A search was carried out in the following databases: PubMed, ScienceDirect, SciELO, ClinicalKey, EMBASE, Lilacs, OVID, APA and PsycNET. English and Spanish were selected without being limited by type of study or year of publication. Finally, a qualitative synthesis was conducted. RESULTS: ADHD development could be related to exposure to adverse factors in the family, school or social environment. It has been proposed as an explanatory mechanism that adversity interacts with genetic variants and leads to neurobiological changes. There may also be a gene-environment correlation whereby individual hereditary characteristics increase the risk of exposure to adversity, and indirectly increase the probability of developing ADHD. Research on psychosocial adversity represents a big challenge, not only due to the complexity of its construct, but also to the effect of subjective perception of a given event. CONCLUSIONS: ADHD aetiology is complex and involves the interaction of both genetic and environmental factors, in which these factors correlate and cause the disorder. The study of the role of psychosocial adversity in ADHD is fundamental, but it remains a task that entails great difficulties.

RESUMO

INTRODUCTION: Studies that have compared the cognitive alterations of the children of parents with bipolar disorder (CPBD) versus the children of control parents (CCP), present heterogeneous results due to the studies' methodological differences, the age of the population studied, and the lack of standardisation of the measures used for the different neurocognitive domains. The objective was to compare the neurocognitive profile of CPBD versus CCP to observe if there are differences that could be proposed as possible endophenotypes of BD. RESULTS: A total of 107 individuals (51 CPBD, and 56 CCP) with ages between 6 and 16 (mean, 12.2±2.80) years of age were evaluated. Seventy-four point five percent of the CPBD group had some disorder compared to 67.9% of the CCP group. Tests such as letter-F phonemic verbal fluency, letter-S phonemic verbal fluency, overall F-A-S phonemic verbal fluency, story recall and retrieval, and Wisconsin perseverative errors showed a difference with a small effect size, but with a high degree of uncertainty. CONCLUSIONS: The CPBD did not have differences in their neurocognitive profile in comparison with CCP. Both groups have a high prevalence of psychopathology, which is a factor that could explain the lack of differences in neurocognitive performance.

RESUMO

INTRODUCTION: Predominant polarity (PP) has been proposed as a specifier of bipolar disorder (BD) due to its relationship with clinical and prognostic variables. It is possible that this is due to a different underlying neurobiology, in such a way that the changes found by structural nuclear magnetic resonance imaging (sMRI) in BD are different and specific. OBJECTIVES: To explore findings of structural neuroimaging in patients with BD type I (BD-I) according to PP. METHODS: Cross-sectional study that evaluated 77 patients with BD-I using the DIGS interview. PP was established using the operative definition of two-thirds of all affective episodes throughout life to classify PP as manic (MPP), depressive (DPP) or indeterminate (IPP). MRI was performed during the euthymia phase to measure intracranial structures. The data obtained was analysed using a linear regression model adjusted for confounding variables (drug use, alcohol use, psychoactive substance use) and were compared between the three groups finding the standardised mean difference (SMD). RESULTS: Differences with adequate effect size were found in three brain structures after adjusting for confounding variables, specifically in the right fusiform gyrus and the left lingual gyrus, which were greater in the DPP group than in the MPP group (SMD = 0.92; 95% CI = 0.34-1.49 and SMD = 0.78; 95% CI = 0.21-1.35). Likewise, in the right thalamus, it was shown to be greater in the IPP group compared to MPP group (SMD 0.89, 95% CI = 0.31-1.46). CONCLUSIONS: A reduction in the thickness of the right fusiform gyrus and the left lingual gyrus, as well as the right thalamic volume was observed in patients with BD-I with PPM, which supports the hypothesis that PP has a plausible neurobiological correlate and could have potential utility as a BD specifier.

RESUMO

Content-based validity can be defined as the evidence of the degree to which the items of an instrument represent the construct to be inferred. It is the initial and unavoidable step for evaluating other sources of validity. However, it is one of the least reported psychometric properties in development of health measurement scales. That is why it is considered a challenge that must be overcome with the recognition of its value. In this narrative review, the concept of content as evidence of validity is revised and methods for evaluation are synthesized with an algorithm.

RESUMO

INTRODUCTION: Lithium treatment of bipolar disorder (BD) has been associated with less cognitive impairment and fewer changes in structural brain anatomy compared to other treatments. However, the studies are heterogeneous and few assess whether these effects are related. The objective of this study was to evaluate and relate cognitive performance and structural neuroanatomy in patients treated with and without lithium. METHODS: Cross-sectional study that included 48 subjects with BD-I, of which 22 were treated with lithium and 26 without lithium. Performance was assessed on Wechsler III (WAIS III), TMT A and B (Trial Making Test) neuropsychological tests, California verbal learning test (CVLT), Rey complex figure test and Wisconsin card sorting test. Brain structures obtained by magnetic resonance imaging (MRI) were evaluated. The standardised mean difference (SMD) between both groups was calculated, adjusted for confounding variables using a propensity score, and the Spearman correlation coefficient (ρ) was used to assess the relationship between cognitive performance and neuroanatomical regions. RESULTS: Compared to the group without lithium, the group with lithium had fewer perseverative errors in the Wisconsin test (SMD = -0.69) and greater left and right cortical areas (SMD = 0.85; SMD = 0.92); greater surface area in the left anterior cingulate (SMD = 1.32), right medial orbitofrontal cortex (SMD = 1.17), right superior frontal gyrus (SMD = 0.82), and right and left precentral gyrus (SMD = 1.33; SMD = 0.98); greater volume of the right amygdala (SMD = 0.57), right hippocampus (SMD = 0.66), right putamen (SMD = 0.87) and right thalamus (SMD = .67). In the lithium group, a correlation was found with these errors and the thickness of the left precentral gyrus (ρ = -0.78), the volume of the right thalamus (ρ = -0.44), and the right amygdala (ρ = 0.6). CONCLUSIONS: The lithium group had better cognitive flexibility and greater dimension in some frontal and subcortical cortical regions. Furthermore, there was a moderate to high correlation between performance in this executive function and the thickness of the right precentral gyrus, and the volumes of the thalamus and the right amygdala. These findings could suggest a neuroprotective effect of lithium.

RESUMO

Background: A telehealth mental health programme was designed at the LivingLab of the Faculty of Medicine of the Universidad de Antioquia [University of Antioquia].Objectives: To describe the development and operation of the programme and evaluate the satisfaction of the patients treated during the COVID-19 pandemic in 2020 and 2021.Methods: Descriptive study that details the development of the programme. Data were extracted from medical records to describe the patients who were treated. A satisfaction scale was applied to a random sample and the data were summarised with descriptive statistics.Results: In March 2020 and August 2021, 10,229 patients were treated, with 20,276 treated by telepsychology and 4,164 by psychiatry, 1,808 by telepsychiatry and 2,356 by tele-expertise, with a total of 6,312 visits. The most frequent diagnoses were depressive (36.8%), anxiety (12.0%), and psychotic (10.7%) disorders. Respondents were satisfied to the point that more than 93% would recommend it to another person.Conclusions: The LivingLab telehealth mental health programme allowed for the care of patients with mental health problems and disorders in Antioquia during the first two years of the COVID-19 pandemic, and there was a high degree of satisfaction among the beneficiaries. Therefore it could be adopted in mental health care.

RESUMO

INTRODUCTION: The offspring of bipolar parents (BO) is a high-risk population for inheriting the bipolar disorder (BD) and other early clinical manifestations, such as sleep disturbances. OBJECTIVE: To compare the presence of psychiatric disorders and sleep disturbances of BO versus offspring of control parents (OCP). METHODS: A cross-sectional analytical study was conducted that compared BO versus OCP. The participants were assessed using valid tools to determine the presence of psychiatric symptoms or disorders. The "Sleep Evaluation Questionnaire" and "School Sleep Habits Survey" were used to determine sleep characteristics and associated factors. Sleep records (7-21 days) were also obtained by using an actigraphy watch. RESULTS: A sample of 42 participants (18 BO and 24 OCP) was recruited. Differences were found in the presentation of the psychiatric disorder. The BO group showed a higher frequency of major depression disorder (MDD; P = .04) and Disruptive Mood Dysregulation Disorder (DMDD; P = .04). The OCP group showed a higher frequency of Attention Deficit and Hyperactivity Disorder (ADHD; P = .65), and Separation Anxiety Disorder (SAD; P = .46). Differences were also found in sleep by using subjective measurements. Compared to the OCP group, BO had a worse perception of quality of sleep (P = .02), a higher frequency of nightmares (P = .01), a shorter total sleep time, and a higher sleep latency. Nevertheless, no differences were found between groups in the actigraphy measurements. CONCLUSIONS: The BO group had a higher frequency of Mood Disorders, and at the same time a higher number of sleep disturbances in the subjective measurements. It is possible that there is an association between mood symptoms, sleep disturbances, and coffee intake. No differences were found in the sleep profile by using actigraphy.

RESUMO

OBJECTIVE: Validate the Self Stigma Of Seeking Help (SSOSH) scale in a population of students of a medical school for its use in Colombia. METHODS: We included 384 medical students from the city of Medellín. Initially, two direct translations were made, two back translation and one pilot test. The internal consistency, test-retest repeatability and structural, convergent, divergent and discriminative construct validity were then evaluated. RESULTS: A easy-to-understand and to fill out Spanish version was obtained. The internal consistency of the scale was adequate (Cronbach's alpha = .80; 95%CI, .77-.83) as well as the test-retest repeatability (CCI = .77; 95%CI, .63-.86). The Confirmatory Factor Analysis showed a good fit with the one-dimensional structure (RMSEA = .073; IC90%, .056-.089; CFI = .968; TLI = .977; WRMR = .844). The convergent validity was supported by the correlation with the Public Stigma scales (ρ = .39) and Attitudes towards Seeking Help (ρ = -0.50) and the divergent validity with the Social Desirability scale (ρ = -0,05). When examining the discriminative validity, differences were found between the scores of those who would be willing to seek professional help when having a mental health problem and those who probably would not (Difference of means = 4.9; 95%CI, 2.99-6.83). CONCLUSIONS: The Colombian version of the SSOSH is valid, reliable and useful for the measurement of the Self-stigma associated with seeking professional help in the university population of the Colombian health sector. Its psychometric properties must be investigated in populations of other programs and outside universities.

The internal consistency, test-retest repeatability and structural, convergent, divergent and discriminative construct validity were then evaluated. RESULTS: A easy-to-understand and to fill out Spanish version was obtained. The internal consistency of the scale was adequate (Cronbach's alpha=.80; 95%CI, .77-.83) as well as the test-retest repeatability (CCI=.77; 95%CI, .63-.86). The Confirmatory Factor Analysis showed a good fit with the one-dimensional structure (RMSEA=.073; IC90%, .056-.089; CFI=.968; TLI=.977; WRMR=.844). The convergent validity was supported by the correlation with the Public Stigma scales (ρ=.39) and Attitudes towards Seeking Help (ρ= -0.50) and the divergent validity with the Social Desirability scale (ρ=-0,05). When examining the discriminative validity, differences were found between the scores of those who would be willing to seek professional help when having a mental health problem and those who probably would not (Difference of means=4.9; 95%CI, 2.99-6.83).

RESUMO

INTRODUCTION: Attention deficit/hyperactivity disorder (ADHD) has genetic and environmental aetiological factors. There are few publications on the environmental factors. The objective of this review is to present the role of psychosocial adversity in the aetiology and course of ADHD. METHODS: A search was carried out in the following databases: PubMed, ScienceDirect, SciELO, ClinicalKey, EMBASE, Lilacs, OVID, APA and PsycNET. English and Spanish were selected without being limited by type of study or year of publication. Finally, a qualitative synthesis was conducted. RESULTS: ADHD development could be related to exposure to adverse factors in the family, school or social environment. It has been proposed as an explanatory mechanism that adversity interacts with genetic variants and leads to neurobiological changes. There may also be a gene-environment correlation whereby individual hereditary characteristics increase the risk of exposure to adversity, and indirectly increase the probability of developing ADHD. Research on psychosocial adversity represents a big challenge, not only due to the complexity of its construct, but also to the effect of subjective perception of a given event. CONCLUSIONS: ADHD aetiology is complex and involves the interaction of both genetic and environmental factors, in which these factors correlate and cause the disorder. The study of the role of psychosocial adversity in ADHD is fundamental, but it remains a task that entails great difficulties.
