Objective/background: Unmet needs in perinatal mental healthcare are an important public health issue particularly in the context of a stressful life event such as the COVID-19 pandemic but data on the extent of this problem are needed., Aim: The aim of this study is to determine the (1) proportion of women with clinically significant symptoms of perinatal depression, anxiety or comorbid symptoms of depression and anxiety, receiving mental healthcare overall and by country and (2) factors associated with receiving mental healthcare., Method: Women in the perinatal period (pregnancy or up to 6 months postpartum) participating in the Riseup-PPD-COVID-19 cross-sectional study, reported on sociodemographic, social support health-related factors, and COVID-19 related factors, and on symptoms of depression (Edinburgh Postnatal Depression Scale [EPDS]) and anxiety (Generalised Anxiety Disorder [GAD-7]) using self-report questionnaires. Clinically significant symptoms were defined as EPDS ≥ 13 for depression and GAD-7 ≥ 10 for anxiety. Mental healthcare was defined as self-reported current mental health treatment., Results: Of the 11 809 participants from 12 countries included in the analysis, 4 379 (37.1%) reported clinically significant symptoms of depression (n = 1 228; 10.4%; EPDS ≥ 13 and GAD-7 ⟨ 10), anxiety (n = 848; 7.2%; GAD-7 ≥ 10 and EPDS ⟨ 13) or comorbid symptoms of depression and anxiety (n = 2 303; 19.5%; EPDS ≥ 13 and GAD-7 ≥ 10). Most women with clinically significant symptoms of depression, anxiety, or comorbid symptoms of depression and anxiety were not receiving mental healthcare (89.0%). Variation in the proportion of women with clinically significant symptoms of depression and/or anxiety reporting mental healthcare was high (4.7% in Turkey to 21.6% in Brazil). Women in the postpartum (vs. pregnancy) were less likely (OR 0.72; 95% CI 0.59-0.88), whereas women with previous mental health problems (vs. no previous mental health problems) (OR 5.56; 95% CI 4.41-7.01), were more likely to receive mental healthcare., Conclusion: There are high unmet needs in mental healthcare for women with clinically significant symptoms of perinatal depression and/or anxiety across countries during the COVID-19 pandemic. Studies beyond the COVID-19 pandemic and covering the whole range of mental health problems in the perinatal period are warranted to understand the gaps in perinatal mental healthcare., (© 2024 The Authors.

Background: This study aims to describe the relationship between life satisfaction, positive affect, depression and anxiety symptoms with sociodemographic, psychosocial and clinical variables, and to identify the relative importance of these predictor groups., Methods: We evaluated life satisfaction (SWLS), positive affect (PANAS), depressive (PHQ-9), and anxiety (GAI) symptoms and their association with sociodemographic, psychosocial and clinical variables in a multistage, random general population sample of fully functioning individuals aged 60-80 years from the Concepción province and Gran Santiago, Chile ( n = 396). We performed weighted multiple regression analysis, considering the complex sample structure with age group, sex, and geographical area, complemented with general and conditional dominance analyses to estimate the relevance of the predictor groups., Results: We found significant associations with the geographical area, sex, age, education level, household members, having a partner, employment status, caregiver status, economic satisfaction, presence of chronic diseases, medication use, and alcohol use. Satisfaction with health was the most important predictor for positive affect ( p  < 0.001), depressive ( p  < 0.001), and anxiety ( p  < 0.001) symptoms, while alcohol use was the most significant predictor for life satisfaction ( p  < 0.001)., Conclusion: Simultaneously studying the positive and negative dimensions of wellbeing and mental health in older adults allows for a more comprehensive perspective on the challenges faced during this stage of life. This study accounts for previously unknown associations and contributes to the identification of common and specific predictors in both dimensions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Saldivia, Aslan, Cova, Bustos, Inostroza and Castillo-Carreño.)

Background: While there are reviews of the literature on mental health stigma reduction programs, very few have focused on the workplace., Objective: We sought to identify, describe and compare the main characteristics of the interventions to reduce the stigma towards mental health at work., Method: The search of original articles (2007 to 2022) was carried out in the Web of Science Core Collection and Scopus databases, selecting 25 articles from the key terms: 1. Stigma, 2. Workplace, 3. Anti-stigma intervention/program, 4. Mental health., Results: These interventions can be effective in changing the knowledge, attitudes, and behaviors of workers towards people with mental health problems, although further verification of these results is needed as they are limited to date., Discussion and Conclusion: Interventions to reduce stigma in the workplace could create more supportive work environments by reducing negative attitudes and discrimination and improving awareness of mental disorders., (© 2023.

This study aimed to analyse the role of governmental responses to the coronavirus disease 2019 (COVID-19) outbreak, measured by the Containment and Health Index (CHI), on symptoms of anxiety and depression during pregnancy and postpartum, while considering the countries' Inequality-adjusted Human Development Index (IHDI) and individual factors such as age, gravidity, and exposure to COVID-19. A cross-sectional study using baseline data from the Riseup-PPD-COVID-19 observational prospective international study (ClinicalTrials.gov: NCT04595123) was carried out between June and October 2020 in 12 countries (Albania, Brazil, Bulgaria, Chile, Cyprus, Greece, Israel, Malta, Portugal, Spain, Turkey, and the United Kingdom). Participants were 7645 pregnant women or mothers in the postpartum period-with an infant aged up to 6 months-who completed the Edinburgh Postnatal Depression Scale (EPDS) or the Generalised Anxiety Disorder Assessment (GAD-7) during pregnancy or the postpartum period. The overall prevalence of clinically significant depression symptoms (EPDS ≥ 13) was 30%, ranging from 20,5% in Cyprus to 44,3% in Brazil. The prevalence of clinically significant anxiety symptoms (GAD-7 ≥ 10) was 23,6% (ranging from 14,2% in Israel and Turkey to 39,5% in Brazil). Higher symptoms of anxiety or depression were observed in multigravida exposed to COVID-19 or living in countries with a higher number of deaths due to COVID-19. Furthermore, multigravida from countries with lower IHDI or CHI had higher symptoms of anxiety and depression. Perinatal mental health is context-dependent, with women from more disadvantaged countries at higher risk for poor mental health. Implementing more restrictive measures seems to be a protective factor for mental health, at least in the initial phase of the COVID-19., (© 2023. The Author(s).)

Research on the multidimensionality of hallucination-like experiences (HLEs) can contribute to the study of psychotic risk. The Launay-Slade Hallucinations Scale-Extended (LSHS-E) is one of the most widely used tools for research in HLEs, but the correspondence of its paper and online formats has not been established yet. Therefore, we studied the factorial structure and measurement invariance between online and paper-and-pencil versions of LSHS-E in a Chilean population. Two thousand eighty-six completed the online version, and 578 students completed the original paper-and-pencil version. After matching by sex, age, civil status, alcohol and cannabis consumption, and psychiatric treatment received, we selected 543 students from each group. We conducted a confirmatory factor analysis of a four-factor model and a hierarchical model that included a general predisposition to hallucination, explaining the strong relationship between the different types of hallucinations. Both models showed a good fit to the data and were invariant between paper-and-pencil and online versions. Also, the LSHS-E has good reliability in both online and paper-and-pencil formats. This study shows that the online LSHS-E possesses psychometric properties equivalent to the paper-and-pencil version. It should be considered a valuable tool for research of psychosis determinants in the COVID-19 era., Supplementary Information: The online version contains supplementary material available at 10.1007/s12144-021-02497-7., Competing Interests: Conflict of InterestThe authors have no conflicts of interest to declare that they are relevant to the content of this article., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2021.)

This study assessed the effectiveness of a program (called Igual-Mente, Equal-Mind) designed to reduce stigma in primary health care personnel. A random clinical trial was performed (ISRCTN46464036). There were 316 primary care professionals and technicians who were randomized and assigned to the experimental or control group. The program considered as strategies the education, the contact and the development of skills. There were six sessions with the primary care staff and two sessions with the managers of the health centers. It was executed by two facilitators, a professional psychologist and an expert by experience, i.e., a person diagnosed with a severe mental disorder (SMD). Attitudes, social distance, and humane treatment behaviors toward people with SMD were assessed. The intervention was effective in reducing stigma attitudes y social distance towards people diagnosed with SMD. The magnitude of the changes ranged from moderate to high in all these variables and the effects were maintained for four months after the end of the program. Regarding humane treatment behaviors, the effects were less clear. This study shows good results indicating that well-designed interventions can effectively reduce stigma towards people diagnosed with SMD, which is one of the main challenges of health systems., (Copyright © 2021 Elsevier B.V.

Background: There is evidence of negative attitudes among health professionals towards people with mental illness but there is also a knowledge gap on what training must be given to these health professionals during their education. The purpose of this study is to compare the attitudes of students of health sciences: nursing, medical, occupational therapy, and psychology., Methods: A comparative and cross-sectional study in which 927 final-year students from health sciences university programmes were evaluated using the Mental Illness: Clinicians' Attitudes (both MICA-2 and MICA-4) scale. The sample was taken in six universities from Chile and Spain., Results: We found consistent results indicating that stigma varies across university programmes. Medical and nursing students showed more negative attitudes than psychology and occupational therapy students in several stigma-related themes: recovery, dangerousness, uncomfortability, disclosure, and discriminatory behaviour., Conclusions: Our study presents a relevant description of the attitudes of each university programme for education against stigma in the formative years. Results show that the biomedical understanding of mental disorders can have negative effects on attitudes, and that education based on the psychosocial model allows a more holistic view of the person over the diagnosis.

Background: Corona Virus Disease 19 (COVID-19) is a new pandemic, declared a public health emergency by the World Health Organization, which could have negative consequences for pregnant and postpartum women. The scarce evidence published to date suggests that perinatal mental health has deteriorated since the COVID-19 outbreak. However, the few studies published so far have some limitations, such as a cross-sectional design and the omission of important factors for the understanding of perinatal mental health, including governmental restriction measures and healthcare practices implemented at the maternity hospitals. Within the Riseup-PPD COST Action, a study is underway to assess the impact of COVID-19 in perinatal mental health. The primary objectives are to (1) evaluate changes in perinatal mental health outcomes; and (2) determine the risk and protective factors for perinatal mental health during the COVID-19 pandemic. Additionally, we will compare the results between the countries participating in the study., Methods: This is an international prospective cohort study, with a baseline and three follow-up assessments over a six-month period. It is being carried out in 11 European countries (Albania, Bulgaria, Cyprus, France, Greece, Israel, Malta, Portugal, Spain, Turkey, and the United Kingdom), Argentina, Brazil and Chile. The sample consists of adult pregnant and postpartum women (with infants up to 6 months of age). The assessment includes measures on COVID-19 epidemiology and public health measures (Oxford COVID-19 Government Response Tracker dataset), Coronavirus Perinatal Experiences (COPE questionnaires), psychological distress (BSI-18), depression (EPDS), anxiety (GAD-7) and post-traumatic stress symptoms (PTSD checklist for DSM-V)., Discussion: This study will provide important information for understanding the impact of the COVID-19 pandemic on perinatal mental health and well-being, including the identification of potential risk and protective factors by implementing predictive models using machine learning techniques. The findings will help policymakers develop suitable guidelines and prevention strategies for perinatal mental health and contribute to designing tailored mental health interventions., Trial Registration: ClinicalTrials.gov Identifier: NCT04595123 .

Background: This study aimed to assess the measurement properties (reliability, factor structure, and criterion validity) of the Patient Health Questionnaire (PHQ-9) as an instrument for screening major depressive disorder (MDD) in elderly primary care users in Chile. Method: About 582 participants aged between 65 and 80 years were enrolled from primary care centers. They completed the Composite International Diagnostic Interview (CIDI), a survey with sociodemographic characteristics and the PHQ-9. Results: The PHQ-9 revealed an acceptable internal consistency (ω = 0.79 [95% CI: 0.75-0.80] and α = 0.78 [95% CI: 0.75-0.81]); confirmatory factor analysis demonstrated a good fit for both 1- and 2-factor solutions. The chi-square difference test (χ 2 = 0.61, gl = 1, p = 0.43) and correlation between the somatic and the cognitive-effective latent factors were very high ( r = 0.97, p < 0.001), indicating that the 1 factor model was more parsimonious. Utilizing the CIDI as the gold standard, the area under the curve (AUC) was 0.88 (SE = 0.04, 95% CI: 0.84-0.90). The optimal cut-off score of ≥ 6 yielded good sensitivity and specificity for detecting MDD (0.95 and 0.76, respectively). However, considering the clinical utility index, the cut-off score of ≥9 proved to be a more effective marker for discarding cases of MDD. Conclusion: The PHQ-9 has adequate psychometric properties for elderly primary care users. In clinical settings, it showed its greatest utility in ruling out the presence of an MDD, however, its clinical value for identifying possible cases of MDD is limited. In cases above the cut-off point, it is recommended to perform a more thorough evaluation., (Copyright © 2020 Aslan, Cova, Saldivia, Bustos, Inostroza, Rincón, Ortiz and Bühring.)

Background: According to the stress inoculation hypothesis, successfully navigating life stressors may improve one's ability to cope with subsequent stressors, thereby increasing psychiatric resilience., Aims: Among individuals with no baseline history of post-traumatic stress disorder (PTSD) and/or major depressive disorder (MDD), to determine whether a history of a stressful life event protected participants against the development of PTSD and/or MDD after a natural disaster., Method: Analyses utilised data from a multiwave, prospective cohort study of adult Chilean primary care attendees (years 2003-2011; n = 1160). At baseline, participants completed the Composite International Diagnostic Interview (CIDI), a comprehensive psychiatric diagnostic instrument, and the List of Threatening Experiences, a 12-item questionnaire that measures major stressful life events. During the study (2010), the sixth most powerful earthquake on record struck Chile. One year later (2011), the CIDI was re-administered to assess post-disaster PTSD and/or MDD., Results: Marginal structural logistic regressions indicated that for every one-unit increase in the number of pre-disaster stressors, the odds of developing post-disaster PTSD or MDD increased (OR = 1.21, 95% CI 1.08-1.37, and OR = 1.16, 95% CI 1.06-1.27 respectively). When categorising pre-disaster stressors, individuals with four or more stressors (compared with no stressors) had higher odds of developing post-disaster PTSD (OR = 2.77, 95% CI 1.52-5.04), and a dose-response relationship between pre-disaster stressors and post-disaster MDD was found., Conclusions: In contrast to the stress inoculation hypothesis, results indicated that experiencing multiple stressors increased the vulnerability to developing PTSD and/or MDD after a natural disaster. Increased knowledge regarding the individual variations of these disorders is essential to inform targeted mental health interventions after a natural disaster, especially in under-studied populations.

Objective: To determine whether etifoxine, a non-benzodiazepine drug of the benzoxazine family, is non-inferior compared with clonazepam in the treatment of anxiety disorders., Method: A randomized controlled double blind trial with parallel groups was conducted. A total of 179 volunteer patients with a diagnosis of anxiety disorder (DSM-IV), between 18 and 64 years of age, participated in this study. The experimental group received 150 mg/day of etifoxine and the control 1 mg/day of clonazepam, both in three daily doses for 12 weeks. This treatment was completed by 87 participants, and 70 were available for follow-up at 24 weeks from start of treatment. The primary objective was a non-inferiority comparison between etifoxine and clonazepam in the decrease of anxiety symptoms (HAM-A) at 12 weeks of treatment. Secondary outcomes included the evaluation of medication side effects (UKU), anxiety symptoms at 24 weeks of treatment, and clinical improvement (CGI). Data analysis included multiple imputation of missing data. The effect of etifoxine on the HAM-A, UKU, and CGI was evaluated with the intention of treatment, and a sensitivity analysis of the results was conducted. Non-inferiority would be declared by a standardized mean difference (SMD) between clonazepam and etifoxine not superior to 0.31 in favour of clonazepam., Results: Using imputed data, etifoxine shows non-inferiority to clonazepam on the reduction of anxiety symptoms at the 12-week (SMD = 0.407; 95% CI, 0.069, 0.746) and 24-week follow-ups (SMD = 0.484; 95% CI, 0.163, 0.806) and presented fewer side effects (SMD = 0.58; 95% CI, 0.287, 0.889). LOCF analysis shows that etifoxine is non-inferior to clonazepam on reduction of anxiety symptoms and adverse symptoms even when no change was assigned as result to participant whom withdrew. Non-inferiority could be declared for clinical improvement (SMD = 0.326; 95% CI, - 0.20, 0.858)., Conclusion: Etifoxine was non-inferior to clonazepam on reduction of anxiety symptoms, adverse effects, and clinical improvement.

Background: Parenting training is a proven strategy for the promotion of positive parenting practices and for the prevention and treatment of behavior problems in children. The processes that explain this efficacy are less clear. The aim of this study was to assess the mediating role of parenting practice modification, encouraged through the implementation of a universal parenting training program, for the decrease of behavior problems in 3- to 6-year-old children., Method: A cluster randomized trial was carried out in 19 educational centers in low and middle socioeconomic areas. A total of 178 families received the program and 154 of them were the control group. The following parenting practices were assessed: positive reinforcement, involvement, inconsistency, unsuitable treatment behaviors and physical punishment, as well as hostility and humiliation behaviors. Parent-child interaction was also assessed using an observational instrument. A multiple mediation analysis was carried out, identifying the indirect effects., Results: Reduction of harsh discipline and physical punishment, and parental inconsistency mediated the effects observed in the reduction of child behavior problems during the program., Conclusion: Within Chilean families, harsh discipline, physical punishment, and parental inconsistency are important aspects to be considered in the implementation of universal parenting training programs.

Background: Stigma towards people diagnosed with a severe mental disorder (SMD) is one of the main obstacles for these service users to receive timely and relevant healthcare. This study was undertaken to understand how stigmatizing attitudes are demonstrated towards people with SMD in primary healthcare centers (PHC) from the perspective of those affected and primary healthcare professionals., Methods: We used a qualitative exploratory research design to contrast the differences and similarities regarding stigmatizing attitudes towards people with SMD in primary healthcare centers (PHC) from the perspective of two groups: (i) people diagnosed with a severe mental disorder, and (ii) healthcare professionals. Data was collected through semi-structured interviews and discussion groups and subsequently analyzed using Atlas.ti software., Results: Our results indicate that both service users and healthcare professionals manifest stereotypes, prejudices, and discriminatory behavior in health care. In addition, structural aspects of the health system and organizational culture appear to contribute to stigmatization. Both groups agreed that there is a need for healthcare professionals to have more education, specialization, and skill development related to mental health issues., Conclusions: Interventions to reduce the stigma towards people with SMD in PHC must consider delivery of information about mental disorders, development of skills in the healthcare professionals, and modifications in the culture of the health centers., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s) 2020.)

Background: Evidence about the effectiveness of psychosocial interventions to reduce the incidence of depression and anxiety and promote subjective well-being in older people is limited, particularly in Latin-American countries. This study thus aims to assess a program specifically designed to address this issue in persons aged 65 to 80 and attending primary health care centres., Method: Older people who use primary care centres are to be randomly assigned to the program or to a control group. Only independent users will be included; those having had a major depressive disorder or an anxiety disorder in the last 6 months will be excluded. The program is group based; it includes cognitive stimulation, expansion of social support networks and cognitive behaviour strategies. Depressive and anxiety symptoms and disorders, as well as psychological well-being, will be assessed using standardised instruments, once before implementing the program and later, after 18 and 36 weeks., Discussion: Primary care is a setting where interventions to improve mental health can be beneficial. Providing evidence-based programs that work with older people is a priority for public mental health., Trial Registration: A protocol for this study has been registered prospectively at ISRCTN registry on 25 July 2018. Identifier: ISRCTN32235611 .

Hallucination-like experiences (HLEs) are typically defined as sensory perceptions in the absence of external stimuli. Multidimensional tools, able to assess different facets of HLEs, are helpful for a better characterization of hallucination proneness and to investigate the cross-national variation in the frequencies of HLEs. The current study set out to establish the validity, factor structure, and measurement invariance of the Launay-Slade Hallucinations Scale-Extended (LSHS-E), a tool to assess HLEs. A total of 4419 respondents from 10 countries were enrolled. Network analyses between the LSHS-E and the 3 dimensions of the Community Assessment of Psychic Experiences (CAPE) were performed to assess convergent and divergent validity of the LSHS-E. Confirmatory factor analysis was used to test its measurement invariance. The best fit was a 4-factor model, which proved invariant by country and clinical status, indicating cross-national stability of the hallucination-proneness construct. Among the different components of hallucination-proneness, auditory-visual HLEs had the strongest association with the positive dimension of the CAPE, compared with the depression and negative dimensions. Participants who reported a diagnosis of a mental disorder scored higher on the 4 LSHS-E factors. Small effect size differences by country were found in the scores of the 4 LSHS-E factors even after taking into account the role of socio-demographic and clinical variables. Due to its good psychometric properties, the LSHS-E is a strong candidate tool for large investigations of HLEs.

Background: Simple and brief questionnaires with adequate psychometric properties are useful for the early detection of depressive disorders., Aim: To analyze the psychometric behavior of the Patient Health Questionnaire (PHQ-9) in Chile., Material and Methods: Data were collected from 1,738 adult patients, consulting in primary health care centers. The values obtained in the PHQ-9 were compared with those of the Composite International Diagnostic Interview (CIDI)., Results: The mean score of PHQ-9 was 4.85 ± 5.57. Internal consistency indices were high. McDonald's ω coefficient of was 0.90 and Cronbach alpha 0.89. A confirmatory factor analysis showed a good fit of the one-dimensional model. Using a cutoff score of seven determined with the receiver operating characteristic (ROC) curve, the sensitivity and specificity of the instrument were 0.8 and 0.7, when compared with CIDI diagnoses., Conclusions: PHQ-9 is a useful instrument for the screening of depressive disorders in primary health care centers in Chile.

Objective: To describe the availability of local mental health (MH) services in small MH catchment areas in Central Chile, using a bottom-up approach., Methods: MH services of 19 small MH catchment areas in five health districts of Central Chile that provide health care to more than 4 million inhabitants were assessed using DESDE-LTC (Description and Evaluation of Services and Directories in Europe for Long-Term Care), a tool for standardized description and classification of LTC health services, in a study conducted in 2012 ("DESDE-Chile") designed to complement other studies conducted in 2004 and 2012 at the national and regional level using the World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS). Key informants from national, regional, and local health authorities were contacted to compile a comprehensive list of MH services or facilities (health, social services, education, employment, and housing). The analysis of local care provision covered three criteria-service availability, placement capacity, and workforce capacity., Results: The study detected disparities in all three criteria (availability and placement and workforce capacity) across the five health districts, between urban and rural areas, and between neighboring urban areas. Analysis of service availability revealed differences in the weight of residential services versus day and outpatient care. The Talcahuano area could be considered a benchmark of MH care in Central Chile, based on its service provision patterns, and the criteria of the community care model. The list of MH services identified in this study differed from the one generated in the 2012 WHO-AIMS study., Conclusions: This survey of local MH service provision in small catchment areas using the DESDE-LTC tool provided MH service provision data that complemented information collected in other studies conducted at the national/regional level using the WHO-AIMS tool. The bottom-up approach applied in this study would also be useful for the assessment of equity and accessibility and local planning., Competing Interests: Conflicts of interest. None.

Objective: To understand the mental health treatment gap in the Region of the Americas by examining the prevalence of mental health disorders, use of mental health services, and the global burden of disease., Methods: Data from community-based surveys of mental disorders in Argentina, Brazil, Canada, Chile, Colombia, Guatemala, Mexico, Peru, and the United States were utilized. The World Mental Health Survey published data were used to estimate the treatment gap. For Canada, Chile, and Guatemala, the treatment gap was calculated from data files. The mean, median, and weighted treatment gap, and the 12-month prevalence by severity and category of mental disorder were estimated for the general adult, child-adolescent, and indigenous populations. Disability-adjusted Life Years and Years Lived with Disability were calculated from the Global Burden of Disease study., Results: Mental and substance use disorders accounted for 10.5% of the global burden of disease in the Americas. The 12-month prevalence rate of severe mental disorders ranged from 2% - 10% across studies. The weighted mean treatment gap in the Americas for moderate to severe disorders was 65.7%; North America, 53.2%; Latin America, 74.7%; Mesoamerica, 78.7%; and South America, 73.1%. The treatment gap for severe mental disorders in children and adolescents was over 50%. One-third of the indigenous population in the United States and 80% in Latin America had not received treatment., Conclusion: The treatment gap for mental health remains a public health concern. A high proportion of adults, children, and indigenous individuals with serious mental illness remains untreated. The result is an elevated prevalence of mental disorders and global burden of disease., Competing Interests: Conflict of interests. None declared.

Background: Evidence for the effectiveness of parental training as a strategy for promotion of positive parental practices and prevention of child behavior problems in low and middle income countries is not conclusive. This study aims to assess the effectiveness of a universal positive parental training program designed for this context, "Día a Día" UdeC © ("Day by Day" University of Concepción), in Chilean preschoolers' families (3-6 years old children). Methods: A cluster randomized controlled trial (cRCT) was carried out in 19 preschool education centers. There were two treatment arms: 10 centers (including 178 families) were randomly assigned to the intervention group and nine centers (including 154 families) were assigned to the waiting list control condition. Intervention groups received Day by Day UdeC, a six group sessions program for parents, including two group sessions for preschool educators, focused in affective communication; daily and child-directed play; directed attention; routines and transitions; reinforcement and incentive programs; planned inattention-ignore and time out; and logical consequences. Parental practices, parental satisfaction, and presence of children behavioral problems were examined at two-time points: T1 (4 weeks before intervention) and T2 (5-6 weeks after intervention). Results: Intention-to-treat analysis shows a reduction in physical punishment and an increase in parental involvement, as well as a reduction in children behavioral problems. A per-protocol analysis revealed an additional effect: increase in observed parental practices. Conclusion: This cRCT provided evidence for the effectiveness of a parental training program for the promotion of positive parental practices in low and middle income countries. The observed effects of the program in decreasing physical punishment and children's behavioral problems make it a promising strategy for prevention purposes. Trial Registration: This study was registered under ISRCTN.com (ISRCTN90762146; https://doi.org/10.1186/ISRCTN90762146).

Background: Natural disasters are associated with a variety of negative health consequences, including enhanced suicide risk. Factors that moderate the relationship between disaster exposure and enhanced suicide risk are unknown. The aim of the current study was to determine whether pre-disaster PTSD moderates the association between change over time in thoughts of death, suicidal ideation (SI), suicide plans, and suicide attempts (SA) from pre- to post-disaster., Methods: Participants (n = 2832) were recruited from Chile as part of the larger PREDICT study and completed a measure of lifetime PTSD and panic disorder at baseline and a lifetime death/suicide measure at baseline in 2003 and again 6, 12, and 24 months later (i.e. "pre-disaster"). One year following a major earthquake and tsunami in 2010 (i.e., "post-disaster"), participants completed another death/suicide measure., Results: Both those with and without pre-disaster PTSD experienced significant increases in SI from pre- to post-disaster. However, pre-disaster PTSD was associated with significantly accelerated increases in thoughts of death and SI from pre-to post-disaster. At nearly all time-points, pre-disaster PTSD was associated with higher thoughts of death and SI, suicide planning, and SA. In contrast, panic disorder did not moderate the association between time and changes in SI., Limitations: There was a long time-gap between pre-disaster and post-disaster, with limited data about what occurred during this time., Conclusion: Pre-disaster PTSD is an important predictor of increased SI following a natural disaster, and groups with pre-disaster PTSD should be prioritized for receipt of mental health resources following a natural disaster., (Copyright © 2018 Elsevier B.V.

Introduction: Social stigma is the assigning of negative stereotypes to people with schizophrenia. Different measurement tools have been used to evaluate this, including knowledge scales. The aim of this study was to evaluate the public stigma by measuring this knowledge and relate the degree of information with variables that have shown to influence on stigma presented by the affected population., Methods: The sample was composed of 399 people and the inclusion criterion was being between 18 and 65 years of age. The "Questionnaire of knowledge on schizophrenia" was applied, as well as a questionnaire to collect sociodemographic information. Participants were recruited in places with large crowds. The following analyses were performed: multiple correlations, non-parametric bivariate and hierarchical clusters., Results: The questionnaire had two dimensions: "Beliefs on the knowledge of schizophrenia" and "Attitudes towards schizophrenia". There are significant differences between them, and the contact with people with SMI. In the analysis of clusters, there was difference in the two groups according to the combination of the two dimensions of the tools., Conclusions: It is highlighted that none of the dimensions measures true knowledge, and the questionnaire has an attitudinal dimension. More than contact itself, it is the type of interaction of a relevant variable at the level of stigma that questions the traditional hypothesis of contact. Further research is required on the characteristics of the tool and the aspects of the contact associated to a lower level of stigma in the population., (Copyright © 2017 Asociación Colombiana de Psiquiatría.

Background The knowledge of predictive factors in depression should help to deal with the disease. Aim To assess potential predictors of remission of major depressive disorders (MDD) in secondary care and to propose a predictive model. Material and Methods A 12 month follow-up study was conducted in a sample of 112 outpatients at three psychiatric care centers of Chile, with baseline and quarterly assessments. Demographic, psychosocial, clinical and treatment factors as potential predictors, were assessed. A clinical interview with the checklist of DSM-IV diagnostic criteria, the Hamilton Depression Scale and the List of Threatening Experiences and Multidimensional Scale of Perceived Social Support were applied. Results The number of stressful events, perceived social support, baseline depression scores, melancholic features, time prior to beginning treatment at the secondary level and psychotherapeutic sessions were included in the model as predictors of remission. Sex, age, number of previous depressive episodes, psychiatric comorbidity and medical comorbidity were not significantly related with remission. Conclusions This model allows to predict depression score at six months with 70% of accuracy and the score at 12 months with 72% of accuracy.

Background: With an increasing number of individuals surviving natural disasters, it is crucial to understand who is most at risk for developing post-traumatic stress disorder (PTSD). The objective of this study was to prospectively examine the role that pre-existing psychopathology plays in developing PTSD after a disaster., Methods: This study uses data from a prospective 5-wave longitudinal cohort (years 2003-11) of Chilean adults from 10 health centres ( N  = 1708). At baseline, participants completed the Composite International Diagnostic Interview (CIDI), a comprehensive psychiatric diagnostic instrument. In 2010, the sixth most powerful earthquake on record struck Chile. One year later, a modified version of the PTSD module of the CIDI was administered. Marginal structural logistic regressions with inverse probability censoring weights were constructed to identify pre-disaster psychiatric predictors of post-disaster PTSD., Results: The majority of participants were female (75.9%) and had a high-school/college education (66.9%). After controlling for pre-disaster PTSD, pre-existing dysthymia [odds ratio (OR) = 2.21; 95% confidence interval (CI) = 1.39-3.52], brief psychotic disorder (OR = 2.67; 95% CI = 1.21-5.90), anxiety disorders (not including PTSD; OR = 1.49; 95% CI = 1.27-1.76), panic disorder (OR = 2.46; 95% CI = 1.37-4.42), agoraphobia (OR = 2.23; 95% CI = 1.22-4.10), social phobia (OR = 1.86; 95% CI = 1.06-3.29), specific phobia (OR = 2.07; 95% CI = 1.50-2.86) and hypochondriasis (OR = 2.10; 95% CI = 1.05-4.18) were predictors of post-disaster PTSD. After controlling for pre-disaster anxiety disorders, dysthymia, and non-affective psychotic disorders, individuals with pre-disaster PTSD (vs those without pre-disaster PTSD) had higher odds of developing post-disaster PTSD (OR = 2.53; 95% CI = 1.37-4.65)., Conclusions: This is the first Chilean study to demonstrate prospectively that pre-disaster psychiatric disorders, independent of a prior history of other psychiatric disorders, increase the vulnerability to develop PTSD following a major natural disaster., (© The Author 2016; all rights reserved.

Background: Depression is considered the second leading cause of disability worldwide., Aim: To describe the clinical characteristics and the evolution of major depressive disorder (MDD) in secondary care. To evaluate the association between socio-demographic and clinic variables with the first or recurrent major depressive events (MDE)., Material and Methods: Clinical features, treatment, remission and duration of MDE were evaluated during a follow up lasting 12 months in 112 participants aged 44 ± 15 years (79% women). Patients were assessed as outpatients every three months at three psychiatric care centers of Chile. Clinical interviews were carried out using DSM-IV diagnostic criteria checklists and the Hamilton Depression Scale was applied., Results: Most patients were referred from primary care. The mean time lapse for referral to the secondary level was 10.8 months. Most patients had episodes that were recurrent, severe, with a high rate of psychosis, with suicide attempts and melancholic features and with psychiatric and medical comorbidities. Remission rate was 27.5%. In only 16 % of patients, the episode lasted six months or less. The group with recurrent episodes had different age, sex and clinical features., Conclusions: MDD treated at the secondary care level is severe and its symptoms are intense. The time lapse prior to referral was prolonged. Primary care management and referral of these patients should be studied more closely.

The Alabama Parenting Questionnaire (APQ) is a well-known tool to assess empirically identified aspects of positive and negative parenting practices. This study evaluates the psychometric properties of an adapted version of the APQ for its use with parents of children between 2 and 6 years of age in Chile. The participants were 557 parents of children aged 2 to 6 years. A confirmatory factor analysis showed that the best fit was obtained by a four-factor model (positive reinforcement, parental involvement, inconsistency of disciplinary practices, and punitive practices). The invariance analysis for this model by sex and social composition was positive. Disciplinary inconsistency and punitive practices were correlated with externalized and internalized behaviors in children. Results suggest that this adaptation of the APQ may result in a useful tool for clinical and research purposes in this age group., (© 2017 Michigan Association for Infant Mental Health.)

Diabetic cardiomyopathy refers to the manifestations in the heart as a result of altered glucose homeostasis, reflected as fibrosis, cellular hypertrophy, increased oxidative stress, and apoptosis, leading to ventricular dysfunction. Since physical exercise has been indicated as cardioprotective, we tested the hypothesis that high-intensity exercise training could reverse the cardiac maladaptations produced by diabetes. For this, diabetes was induced in rats by a single dose of alloxan. Diabetic rats were randomly assigned to a sedentary group or submitted to a program of exercise on a treadmill for 4 weeks at 80% of maximal performance. Another group of normoglycemic rats was used as control. Diabetic rat hearts presented cardiomyocyte hypertrophy and interstitial fibrosis. Chronic exercise reduced both parameters but increased apoptosis. Diabetes increased the myocardial levels of the mRNA and proteins of NADPH oxidases NOX2 and NOX4. These altered levels were not reduced by exercise. Diabetes also increased the level of uncoupled endothelial nitric oxide synthase (eNOS) that was not reversed by exercise. Finally, diabetic rats showed a lower degree of phosphorylated phospholamban and reduced levels of SERCA2 that were not restored by high-intensity exercise. These results suggest that high-intensity chronic exercise was able to reverse remodeling in the diabetic heart but was unable to restore the nitroso-redox imbalance imposed by diabetes.

Background: Screening instruments are required for the detection of depressive disorders by primary care practitioners., Aim: To develop a screening instrument to detect depression, based on data gathered interviewing patients attending primary health care settings., Material and Methods: The instrument was constructed with data about factors associated or triggering a depressive disorder obtained from 3,000 patients consulting for general morbidity. All patients answered the Composite International Diagnostic Interview, (version 2.1, section depression) and an inventory containing 39 risk factors for depression, obtained from the literature. A multiple imputation method using chained equations was carried out. Using a binary logistic regression with backward selection, an equation for depression screening was obtained. The c-index was calculated to estimate discriminating power of the model. A shrinkage factor was estimated to adjust the predictive model., Results: Estimations were carried out with data from 2,552 patients with a median age of 47 years (73% women). Fifty five percent lived with a partner and 45% had basic studies. The method selected 14 significant predictors, with a shrinkage value of 0.861 and a c-index of 0.838 (95% confidence intervals 0.82-0.86)., Conclusions: The instrument has adequate psychometric properties as a screening tool for depression in primary health care.

Background: Serotonin plays a central role regulating mood and on the development of depressive disorders., Aim: To study whether 5HTTLPR functional polymorphisms in the serotonin transporter gene or the Monoamine oxidase A gene (uMAOA) were risk markers for depression., Material and Methods: The Composite International Diagnostic Interview (CIDI) was applied to 1,062 consultants in primary health care centers aged between 18 and 75 years to establish the diagnosis of depression. A sample of saliva was obtained for DNA extraction and genetic analyses., Results: No association between the presence of depressive disorders and 5HTTLPR (ss) or uMAOA (3/3) risk genotypes was found. Psychological abuse and the presence of two or more life events were found to be predictors of depression in the studied sample., Conclusions: In this study, 5HTTLPR and uMAOA polymorphisms were not risk factors for depression. However, psychological abuse and the presence of two or more life events were risk factors for depressive disorders.

Postpartum depression (PPD) is a common condition worldwide and most of the available information is about treatment rather than prevention. This paper is an update on prevention and treatment of PPD. A simple review of the literature and a critical review of papers' methodology and conclusions was carried out. There is a consensus of the preeminence of psychosocial factors in the genesis of PPD. Considering the complications when the condition is not treated, it is of the utmost importance to implement early detection and management strategies. The use of psychosocial preventive interventions is an alternative that has support in the literature and should be seriously considered.
