Objective: The goal of this study was to report on the development and early usability of a new interactive mHealth app for reducing cardiovascular risk in primary care patients of low socioeconomic status attending clinics in Chile. Design: Mixed-methods design with qualitative and quantitative components. Setting: Three Chilean primary care clinics located in one urban (Santiago) and two rural areas (San Clemente and Chiguayante). Each clinic serves a population of about 24,000 people of generally low socioeconomic status with an average of 8.5 years of education. Methods: A qualitative co-design participatory framework was used to develop the "Mi Salud-APS" mHealth app. Three iterations of virtual workshops were held with healthcare providers and patient participants to develop the new app. Once developed, the usability phase identified, invited and followed up for 3 months a sample of primary care patients with moderate (N = 119) or high (N = 329) cardiovascular risk. Results: A total of 24 healthcare providers and 24 patients participated in the developmental workshops. Three emergent categories represented the core attributes for the mHealth app design: 'Friendly', 'Interactive' and 'Pertinent'. In the usability phase of the sample of 448 patients, 98% downloaded the app, and 64.6% of them logged in and used it for an average of 1.46 (0.5-10) times weekly. Conclusion: Findings suggest that patient and healthcare provider contributions to the development of the mHealth app accurately reflect the interests and experiences of both groups and together helped achieve the high usability levels observed among primary care patients enrolled in clinics in underserved communities.

Digital competences are widely regarded as the key competences as defined by various international organizations, such as the European Commission (2018) and the OECD (2022). Given their paramount importance across all facets of contemporary society, a thorough examination of their developmental aspects becomes imperative. The study was conducted at a Chilean state-run university, which stands as the second largest institution in terms of student enrollment. Utilizing a quantitative survey-based methodology, this research study seeks to characterize the level of digital competences among Year-1 students pursuing undergraduate programs. Furthermore, it aims to compare the competence levels of two prominent student groups, distinguished by their distinct secondary schooling pathways, namely, technical-vocational education (TVSE) and scientific-humanistic education (SHSE). For the purpose of data collection, the CompDig-Ped test, aligned with the European framework for digital competences (DigComp), has been employed as the research instrument. The key findings of this study underscore significant disparities in digital competence levels between students originating from SHSE and TVSE secondary school trajectories, with TVSE students demonstrating comparatively lower levels of digital competence. These outcomes are congruent with existing research, which highlights the challenges encountered by technical-vocational secondary education in Chile over an extended period of time.

Background: In Latin America, there is limited research on the prevalence of mental disorders in children and adolescents. This Chilean survey is the first national representative survey in the Latin American region to examine the prevalence of Diagnostic and Statistical Manual-IV (DSM-IV) psychiatric disorders in the region in children and adolescents. Methods: Subjects aged 4-18 were selected using a stratified multistage design. The Diagnostic Interview Schedule for Children version IV (DISC-IV) was used to obtain 12-month DSM-IV diagnoses of affective, anxiety, conduct and substance use disorders, and supplemented with questionnaires examining family risk factors, family income, and service utilization. The parent or the primary caretaker was interviewed for children, aged 4-11, using the DISC-IV; however, adolescents, aged 12-18, were directly interviewed. Results: A sample of 1558 children and adolescents was evaluated. Using the most stringent DISC-IV impairment algorithm, the prevalence rate for any psychiatric disorders was 22.5% (19.3% for boys and 25.8% for girls). The prevalence rate was higher among the children, aged 4-11, in comparison with adolescents, aged 12-18 (27.8% and 16.5%, respectively). Less than half of the subjects in need of services sought some form of assistance. Nearly a quarter of those using services did not present with a psychiatric diagnosis in the past year. Comorbidity was found in 24.8% of those with a disorder, but only 6.3% had three or more diagnoses. Conclusions: The prevalence of psychiatric disorders in Chile is high among children and adolescents. This study highlights the increasing need to reevaluate mental health services provided to children and adolescents in Latin America. (Contains 5 tables.)

The Mini Mental State Examination (MMSE) is used widely internationally. Data on population age and gender distribution of MMSE scores outside of the US is rare. The Composite International Diagnostic Interview (CIDI), which incorporates the MMSE, was administered to a household sample of 2978 individuals age 15 and older in Chile. DSM-III-R lifetime prevalence rates were estimated. The average MMSE score ranged from 16-29 depending on the level of educational attainment. Sociodemographic variables, including age marital status, urban-rural and income, impacted MMSE scores. When the MMSE scores were controlled for sociodemographic variables, those with any psychiatric disorder had significantly lower scores; however, specific diagnoses did not affect MMSE scores.

Objectives: To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in Santiago, Chile, as part of a national sample. Method: subjects from 4 to 18 years of age were selected in an aleatory stratified multistage fashion. As part of a national sample, 10 counties in Santiago were selected, then blocks, homes and the child or adolescent to be interviewed. Psychology graduate students applied the Spanish computer version of DISC-IV, as well as a questionnaire on family risk factors, socioeconomic index and service use. Results: a sample of 792 children and adolescents was evaluated, obtaining 76.7% of participation. Using the most stringent impairment algorithm, the prevalence for any psychiatric disorders was 25.4%, being 20.7% in boys and 30.3% in girls, mainly explained by anxious and affective disorders. Prevalence was higher in the 4-11 years of age than in the 12-18 (31.9% and 18.2% respectively). This difference was mainly accounted for by disruptive disorders. Prevalence of anxious disorders was the highest, but less associated with impairment, while most of the children and adolescents with affective disorders were impaired. Conclusions: prevalence of psychiatric disorders in Santiago is high in this age group, and this study will be used for improving mental health services. [Copyright &y& Elsevier]

Background:  In Latin America, there is limited research on the prevalence of mental disorders in children and adolescents. This Chilean survey is the first national representative survey in the Latin American region to examine the prevalence of diagnostic and statistical manual-IV (DSM-IV) psychiatric disorders in the region in children and adolescents., Methods:  Subjects aged 4-18 were selected using a stratified multistage design.

Purpose: To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in Santiago, Chile, as part of a national sample., Method: Subjects aged 4-18 were selected using a stratified multistage design. First, ten municipalities/comunas of Santiago were selected; then the blocks, homes, and child or adolescent to be interviewed were chosen. Psychology graduate students administered the Spanish-language, computer-assisted version of DISC-IV that estimated DSM-IV 12-month prevalence., Results: A total of 792 children and adolescents were evaluated, with a participation rate of 76.7%. The most stringent impairment DSM-IV DISC algorithm for psychiatric disorders revealed a prevalence of 25.4% (20.7% for boys and 30.3% for girls). The majority of the diagnoses corresponded to anxiety and affective disorders. Prevalence was higher in children aged 4-11 (31.9%) than in adolescents aged 12-18 (18.2%). This difference was mainly accounted for by disruptive disorders in the younger age group. Anxiety disorders had the highest prevalence, although impairment was low. In contrast, most children and adolescents with affective disorders were impaired., Conclusions: In Santiago, the prevalence of psychiatric disorders in children and adolescents was high. This study helps raise awareness of child and adolescent mental health issues in Spanish-speaking Latin America and serves as a basis for improving mental health services.

Background: The knowledge about prevalence of psychiatric disorders in all age groups is fundamental to plan an adequate mental health care., Aim: To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in the province of Cautin, Chile., Material and Methods: Subjects aged between 4 and 18 years were selected in an aleatory stratified multistage fashion. As part of a national sample, four counties in Cautín were selected, then blocks, homes and the child or adolescent to be interviewed. Psychology graduate students applied the Spanish computer version of DISC-IV, as well as a questionnaire on family risk factors, socioeconomic index and service use., Results: A sample of 272 children and adolescents was evaluated, obtaining 93,4% of participation. Using the most stringent impairment algorithm, the prevalence rate for any psychiatric disorder was 16.8%, being 16.5% in boys and 17.1% in girls and mainly explained by anxiety and affective disorders. Prevalence was practically the same in the group aged 4 to 11 years than in those aged 12 to 18 years (16.7% and 16.8% respectively). Prevalence of anxiety disorders was the highest, but less associated with impairment. On the other hand, all children and adolescents with affective disorders were impaired., Conclusions: The prevalence of psychiatric disorders in Cautín is high in children and adolescents.

Background: In this study we examined the prevalence rates of post-traumatic stress disorder (PTSD), types of trauma most often associated with PTSD, the co-morbidity of PTSD with other lifetime psychiatric disorders, which disorders preceded PTSD, and gender differences in PTSD and trauma exposure in a representative sample of Chileans., Method: The DSM-III-R PTSD and antisocial personality disorder modules from the Diagnostic Interview Schedule (DIS) and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic Interview (CIDI) were administered to a representative sample of 2390 persons aged 15 to over 64 years in three cities in Chile., Results: The lifetime prevalence of PTSD was 4.4% (2.5% for men and 6.2% for women). Among persons exposed to trauma, rape was most strongly associated with PTSD. Onset of PTSD significantly increased the risk of developing each of the 10 other tested disorders. Among those exposed to trauma, women were significantly more likely to develop PTSD, after controlling for assaultive violence., Conclusions: This study highlights the importance of investigating the prevalence of PTSD, patterns of co-morbidity of PTSD, and gender differences in PTSD in non-English-speaking countries.

Background: The Mapuche are the largest indigenous group in Chile; yet almost all data on the mental health of indigenous populations are from North America., Aim: The study examines the differential DSM-III-R prevalence rates of psychiatric disorders and service utilization among indigenous and non-indigenous community residence., Methods: The Composite International Diagnostic Interview (CIDI) was administered to a stratified random sample of 75 Mapuche and 434 non-Mapuche residents of the province of Cautín. Lifetime prevalence and 12-month prevalence rates were estimated., Results: Approximately 28.4% of the Mapuche population had a lifetime, and 15.7% a 12-month, prevalent psychiatric disorder compared to 38.0% and 25.7%, respectively, of the non-Mapuche. Few significant differences were noted between the two groups; however, generalized anxiety disorder, simple phobia, and drug dependence were less prevalent among the Mapuche. Service utilization among the Mapuche with mental illness was low., Conclusions: This is a preliminary study based on a small sample size. Further research on the mental health of indigenous populations of South America is needed.

Background: The Diagnostic and Statistic Manual (DSM) solved the problem of diagnostic criteria for psychiatric diseases. Highly structured interviews such as Composite International Diagnostic Interview (CIDI) allow the evaluation of psychiatric disorders in large samples, with great accuracy., Aim: To report the prevalence rates of psychiatric disorders in a representative sample of Chilean individuals., Material and Methods: The CIDI was administered to 2978 Chilean individuals coming form four provinces. Lifetime and prevalence rates of psychiatric disorders, based in the third revision of the DSM, were calculated., Results: Thirty six percent of the population had a psychiatric disorder at least once in their lifetime and 23% had a disorder in the last six months. The most common lifetime diagnoses were agoraphobia in 11%, major depressive disorders in 9%, dysthymia in 8% and alcohol dependence in 6%. Only 49% of those with a psychiatric disorder sought medical care, while 4% of those individuals considered devoid of psychiatric illnesses, consulted in a mental health facility., Conclusions: The prevalence of psychiatric disorders in the Chilean population is similar to that of other Spanish speaking populations in Latin or North America.

There is an urgent need in multinational studies for efficient and sensitive tests for the evaluation of dementias. These tests are used to investigate the regional characteristics of dementias, providing possible insight into the different etiologies of the disorders. These tests are also utilized to assess the outcome of treatment interventions at multinational levels. We validated and standardized the Syndrom Kurztest, a brief European neuropsychological test, in a population of elderly Chileans, possessing high levels of illiteracy. In our sample, the SKT was found to be an effective instrument for the diagnosis of dementias, and for differentiating mild-moderate from severe degrees of the disease. There was a good correlation between the scores on the SKT and the age of the participants, but the gender and the years of schooling had no effect. The test is a useful contribution to the study of dementias, found in the aging developing world, particularly because it can be used in illiterate populations.
