Psychometric properties of the GAD-7 (General Anxiety Disorder-7): a cross-sectional study of the Peruvian general population.

BACKGROUND: Anxiety disorders are among the main mental health problems worldwide and are considered one of the most disabling conditions. Therefore, it is essential to have measurement tools that can be used to screen for anxiety symptoms in the general population and thus identify potential cases of people with anxiety symptoms and provide them with timely care. Our aim was to evaluate the psychometric properties of the General Anxiety Disorder-7 scale (GAD-7) in the Peruvian population. METHOD: Our study was a cross-sectional study. The sample included people aged 12 to 65 years in Peru. Confirmatory factor analysis, analysis of measurement invariance, convergent validity with the Patient Health Questionnaire-9 (PHQ-9) and internal consistency analysis were performed. RESULTS: In total, 4431 participants were included. The one-factor model showed the best fit (CFI = 0.994; TLI = 0.991; RMSEA = 0.068; WRMR = 1.567). The GAD-7 score showed measurement invariance between men and women and between age groups (adults vs. adolescents) (ΔCFI < 0.01). The internal consistency of the one-factor model was satisfactory (ω = 0.90, α = 0.93). The relationship between depressive symptoms (PHQ-9) and anxiety symptoms (GAD-7) presented a moderate correlation (r = 0.77). CONCLUSIONS: Our study concluded that the GAD-7 score shows evidence of validity and reliability for the one-factor model. Furthermore, because the GAD-7 score is invariant, comparisons can be made between groups (i.e., by sex and age group). Finally, we recommend the use of the GAD-7 for the general population in the Peruvian context.

Witnessing inter-parental violence in childhood and help-seeking behaviours in violence against women in Peru.

BACKGROUND: Violence against women (VAW) severely impacts their physical and mental health. In some cultures, women can normalize certain types of violence if they were linked to home models in childhood and, eventually, do not seek for help in adulthood. We aimed to determine, in Peruvian women, (1) the association between witnessing violence in their family of origin and VAW experienced in adulthood, (2) the extent to which women who have experienced VAW seek some help, and (3) identify VAW prevalence by Peruvian region. METHODS: Cross-sectional study of secondary data obtained from the 2019 National Demographic and Family Health Survey (ENDES). The outcome was VAW (psychological, physical and sexual violence), whereas the exposure was witnessing violence in the home of origin. Help-seeking behavior was a secondary outcome, for which VAW was the exposure. Prevalence ratios (PR) were estimated to assess both associations, unadjusted and adjusted for covariates (aPR). RESULTS: Data from 14,256 women aged 15 to 49 years were analysed. 51.5% reported having experienced VAW and 43.8% witnessed violence in the home of origin during childhood. Witnessing inter-parental violence in childhood was associated with psychological violence aPR = 1.25 (95% CI: 1.17-1.33), physical aPR = 1.52 (95% CI: 1.38-1.67), and sexual aPR = 1.99 (95% CI: 1.57-2.52). Women who have experienced both types of violence (physical and sexual) were more likely to help-seeking (aPR = 1.30, 95% CI: 1.14-1.50) than women suffering only one type of violence. CONCLUSION: Women who reported having witnessed home violence in their childhood are more likely to experience Violence Against Women (VAW) by their current partner. Physical and sexual violence with a current partner was more associated with witnessing inter-parental violence in childhood, and when physical and sexual violence jointly occurred women were more help-seeking. The southern region of Peru is identified as an area of high vulnerability for women. It is crucial to promote educative and community-based programs aimed at the prevention and early recognition of VAW.

Psychometric Adaptation of a Brief Scale of Child-to-Parent Violence and Intrafamily Violence in Peruvian Adolescents.

Family violence is a critical public health problem in Latin America. In Peru, family violence continues to be difficult to detect and prevent, with child-to-parent violence (CPV) arising as a key issue. This study aimed to do a psychometric adaptation of a brief scale of evaluation of CPV and intrafamily violence in a sample of Peruvian adolescents. Our study analyzed internal structure, internal consistency (with depression, family satisfaction, and anxiety), convergent validity, and measurement invariance. The study population included 570 adolescents living with both parents (50.2% women). Adequate goodness-of-fit indices were found for the full version of CPV and intrafamily violence of nine items (CFI = 0.991; RMSEA = 0.053) and the version with only CPV of six items (CFI = 0.995; RMSEA = 0.074). The latent correlations between CPV with depressive symptoms and anxiety symptoms were greater than 0.40. Our study found that the full version of CPV and intrafamily violence (nine items) and the CPV-only version (six items) were invariant by sex. Reliability was adequate in all cases (ω > 0.70). The scale presents evidence of validity and reliability in Peruvian adolescents. It is suitable for epidemiological research on family violence.

Can working at home be a hazard? Ergonomic factors associated with musculoskeletal disorders among teleworkers during the COVID-19 pandemic: a scoping review.

Objectives. The improvised and massive adoption of remote work in the context of COVID-19 has forced us to adapt homes as workspaces, which could promote development of musculoskeletal disorders (MSDs). This review explores the evidence for ergonomic factors associated with MSDs in teleworkers. Methods. A literature search was conducted in MEDLINE, Embase, Scopus, SciELO and EBSCO. We included observational studies published between March 2020 and October 2021 that included teleworking personnel due to the restrictions of the pandemic. Results. A total of 212 studies were identified, 14 were chosen for complete review. Associated factors were change of work modality (on-site work to telework), use of home environments as workspaces (areas not adapted for work and with low lighting), working furniture (non-ergonomic chairs and desks), use of electronic devices (tablets, cell phones and laptops), organizational factors (working hours, active breaks, sitting time) and individual factors (physical activity practice). Conclusion. Various ergonomic home factors and the characteristics of teleworking - mainly furniture, the environment of work and physical activity - are associated with MSDs. This evidence suggests that the norms and regulation of telework can consider the adaptation of workspace and conditions at home to prevent health problems in the medium and long term.

The impact of COVID-19 pandemic on the quality of life of healthcare workers and the associated factors: A systematic review.

Introduction: The COVID-19 pandemic has exacerbated health issues in healthcare workers which in turn impacts their quality of life. Objective: This review aimed to (i) analyze the impact of the COVID-19 pandemic on the quality of life of healthcare professionals and (ii) identify the associated factors with quality of life. Materials and methods: We conducted a systematic review using the PRISMA guidelines previously registered in PROSPERO (CRD42021253075). The searched in Web of Science, Scopus, MEDLINE and EMBASE databases included original articles published till May 2021. Results: We found 19 articles and 14,352 professionals in total, the median age ranged from 29 to 42.5 years and 37% of the studies used the WHOQOL-BREF instrument to assess the outcome. The report was heterogeneous, 7 studies described global scores and 9 by domains. Depression, anxiety and stress were commonly reported factors affecting professional's quality of life and this was significantly lower among professionals working with COVID-19 patients compared to their counterparts. Conclusion: COVID-19 frontline workers perceived lower quality of life, which was mainly associated with psychological states such as the aforementioned besides to working conditions like not being previously trained in COVID-19 cases. On the other hand, social support, resilience and active coping could improved their quality of life.

Introducción: La pandemia de COVID-19 ha agravado los problemas de salud del personal sanitario, lo que a su vez repercute en su calidad de vida. Objetivo: Esta revisión tiene como objetivo: (a) Analizar el impacto de la pandemia COVID-19 en la calidad de vida de los profesionales sanitarios y (2) Identificar los factores asociados a su calidad de vida. Materiales y métodos: Se realizó una revisión sistemática utilizando las pautas PRISMA previamente registradas en PROSPERO (CRD42021253075). La búsqueda en las bases de datos Web of Science, Scopus, MEDLINE y EMBASE incluyó artículos originales publicados hasta mayo de 2021. Resultados: Se encontraron 19 artículos y 14.352 profesionales en total, la mediana de edad osciló entre 29 y 42,5 años y el 37% de los estudios utilizaron el instrumento WHOQOL-BREF para evaluar el resultado. El informe fue heterogéneo, 7 estudios describieron puntuaciones globales y 9 por dominios. La depresión, la ansiedad y el estrés fueron los factores comúnmente reportados que afectan a la calidad de vida del profesional, y esta fue significativamente menor entre los profesionales que trabajan con pacientes de COVID-19 en comparación con sus homólogos. Conclusión: Los trabajadores de primera línea de COVID-19 percibieron una menor calidad de vida, que se asoció principalmente a estados psicológicos como los mencionados, además de a condiciones de trabajo como no haber recibido formación previa en casos de COVID-19. Por otro lado, el apoyo social, la resiliencia y el afrontamiento activo mejoraron su calidad de vida.

An explanatory model of depressive symptoms from anxiety, post-traumatic stress, somatic symptoms, and symptom perception: the potential role of inflammatory markers in hospitalized COVID-19 patients.

BACKGROUND: The context of the COVID-19 pandemic has harmed the mental health of the population, increasing the incidence of mental health problems such as depression, especially in those who have had COVID-19. Our study puts forward an explanatory model of depressive symptoms based on subjective psychological factors in those hospitalized for COVID-19 with and without biological markers (i.e., inflammatory markers). Therefore, we aim to evaluate the hypotheses proposed in the model to predict the presence of depressive symptoms. METHOD: We conducted a cross-sectional study, using a simple random sampling. Data from 277 hospitalized patients with COVID-19 in Lima-Peru, were collected to assess mental health variables (i.e., depressive, anxiety, post-traumatic stress, and somatic symptoms), self-perception of COVID-19 related symptoms, and neutrophil/lymphocyte ratio (NLR) such as inflammatory marker. We performed a structural equation modeling analysis to evaluate a predictive model of depressive symptoms. RESULTS: The results showed a prevalence of depressive symptoms (11.2%), anxiety symptoms (7.9%), somatic symptoms (2.2%), and symptoms of post-traumatic stress (6.1%) in the overall sample. No association was found between the prevalence of these mental health problems among individuals with and without severe inflammatory response. The mental health indicators with the highest prevalence were sleep problems (48%), low energy (47.7%), nervousness (48.77%), worry (47.7%), irritability (43.7%) and back pain (52%) in the overall sample. The model proposed to explain depressive symptoms was able to explain more than 83.7% of the variance and presented good goodness-of-fit indices. Also, a different performance between the proposed model was found between those with and without severe inflammatory response. This difference was mainly found in the relationship between anxiety and post-traumatic stress symptoms, and between the perception of COVID-19 related symptoms and somatic symptoms. CONCLUSIONS: Results demonstrated that our model of mental health variables may explain depressive symptoms in hospitalized patients of COVID-19 from a third-level hospital in Peru. In the model, perception of symptoms influences somatic symptoms, which impact both anxiety symptoms and symptoms of post-traumatic stress. Thus, anxiety symptoms could directly influence depressive symptoms or through symptoms of post-traumatic stress. Our findings could be useful to decision-makers for the prevention of depression, used to inform the creation of screening tools (i.e., perception of symptoms, somatic and anxiety symptoms) to identify vulnerable patients to depression.

Effects of Anonymity versus Examinee Name on a Measure of Depressive Symptoms in Adolescents.

There is evidence in the literature that anonymity when investigating individual variables could increase the objectivity of the measurement of some psychosocial constructs. However, there is a significant gap in the literature on the theoretical and methodological usefulness of simultaneously assessing the same measurement instrument across two groups, with one group remaining anonymous and a second group revealing identities using names. Therefore, the aim of this study was to compare the psychometric characteristics of a measure of depressive symptoms in two groups of adolescents as a consequence of identification or anonymity at the time of answering the measuring instrument. The participants were 189 adolescents from Metropolitan Lima; classrooms were randomly assigned to the identified group (n = 89; application requesting to write one's own name) or to the anonymous group (n = 100; application under usual conditions), who responded to the Childhood Depression Inventory, short version (CDI-S). Univariate characteristics (mean, dispersion, distribution), dimensionality, reliability, and measurement invariance were analyzed. Specific results in each of the statistical and psychometric aspects evaluated indicated strong psychometric similarity. The practical and ethical implications of the present results for professional and research activity are discussed.

Ethical implications in the evaluation of complex contexts related to COVID-19

Background: The pandemic caused by Sars-cov-2 has generated multiple sustained efforts for its identification, characteristics and mobility of the disease that to date has repercussions worldwide. Given this need, it is necessary to have updated information considering transparent research processes. Method: A critical review of the current literature on COVID-19 research. Conclusions: It is essential to have ethical procedures in the different phases of research that can go beyond personal interests and that guarantee the preservation of people's welfare in the reduction of possible damage to health globally, adequate procedures in the collection of information that is not built to the measure of the researchers, to avoid involuntary segregation of the participants and that this leads to a reduction of significant damage due to implicit biases that are generated by poor planning that pursues the scoop instead of social good.

Introducción: La pandemia ocasionada por el Sars-cov-2 ha genero múltiples esfuerzos sostenidos para su identificación, características y movilidad de la enfermedad que hasta la fecha tiene repercusión a nivel mundial y ante esta necesidad es necesario contar con información de actualiza teniendo en cuento procesos claros de investigación. Método: revisión crítica del cuerpo actual de literatura sobre investigación en COVID-19. Conclusiones: Es imprescindible contar con procedimientos éticos en las diferentes fases de investigación que puedan ir más allá de los intereses personales y que garanticen la preservación del bienestar de las personas en la reducción de posibles daños en la salud de manera global, adecuados procedimientos en la recolección de información que no se encuentren construidos a la medida de los investigadores, para evitar una segregación involuntaria de los participantes y que esto conlleve en una reducción de daños significativos por sesgos implícitos que son generados por una mala planificación que persigue la primicia en lugar de un bien social.

Depression, post-traumatic stress, anxiety, and fear of COVID-19 in the general population and health-care workers: prevalence, relationship, and explicative model in Peru.

BACKGROUND: This study has two aims. First, determine the fit of the fear model to COVID-19, anxiety, and post-traumatic stress in the general population and health-care workers. Second, determine which model best explains the relationship between depression and the triad of fear, anxiety, and post-traumatic stress in both groups. METHOD: A cross-sectional study was conducted using self-reported questionnaires for anxiety, fear of COVID-19, depression, and post-traumatic stress. Information was collected from adults living in Lima, the capital and the most populous city in Peru. The explanatory models were evaluated using a structural equation model. RESULTS: A total of 830 participants were included, including general population (n = 640) and health-care workers (n = 190). A high overall prevalence of depressive symptoms (16%), anxiety (11.7%), and post-traumatic stress (14.9%) were identified. A higher prevalence of depressive, anxious, or stress symptoms was identified in the general population (28.6%) compared to health-care workers (17.9%). The triad model of fear of COVID-19, anxiety, and stress presented adequate goodness-of-fit indices for both groups. A model was identified that manages to explain depressive symptoms in more than 70% of the general population and health-care workers, based on the variables of the triad (CFI = 0.94; TLI = 0.94; RMSEA = 0.06; SRMR = 0.06). In the general population post-traumatic stress mediated the relationship between anxiety and depression (ß = 0.12; 95%CI = 0.06 to 0.18) which was significant, but the indirect effect of post-traumatic stress was not significant in health care workers (ß = 0.03; 95%CI = - 0.11 to 0.19). LIMITATIONS: The prevalence estimates relied on self-reported information. Other variables of interest, such as intolerance to uncertainty or income level, could not be evaluated. CONCLUSIONS: Our study proposes and tests one model that explains more than 70% of depressive symptoms. This explanatory model can be used in health contexts and populations to determine how emotional factors can affect depressive symptoms.

Disability and severe depression among Peruvian older adults: analysis of the Peru Demographic and Family Health Survey, ENDES 2017.

BACKGROUND: Depression is considered a mental health-related disability that affects approximately 350 million people worldwide. On the other hand, it is estimated that 15% of the world's population lives with some form of disability, and this scenario is currently riddled with the global burden of mental disorders, non-communicable diseases and other age-related comorbidities. AIM: To assess the association between disability and depression among Peruvian older adults. METHODS: We used data from the 2017 Peru Demographic and Familiar Health Survey, with a focus on adults aged 50 years and older. Whereas the presence of disability was assessed using different questions of the survey, depression was measured with the Patient Health Questionnaire-9 (PHQ-9). We calculated the adjusted prevalence ratios (aPR) using Poisson regression models with log link function, with their respective 95% confidence intervals (95% CI). RESULTS: From the study population, 5% had a disability. In addition, 43.3% were screened positive for depression (13.2% for moderately severe/severe). After adjusting for confounding variables, disability was associated with moderate and severe depression (aPR: 1.06; 95% CI: 1.01-1.11, aPR: 1.10; 95% CI: 1.05-1.15). CONCLUSION: Disability was positively associated with moderate and severe depression. Public health policies should address the early diagnosis and rehabilitation of patients with any of these problems. Likewise, coping strategies should be promoted among families of persons with disabilities.

Valid group comparisons can be made with the Patient Health Questionnaire (PHQ-9): A measurement invariance study across groups by demographic characteristics.

OBJECTIVE: Analyze the measurement invariance and the factor structure of the Patient Health Questionnaire-9 (PHQ-9) in the Peruvian population. METHOD: Secondary data analysis performed using cross-sectional data from the Health Questionnaire of the Demographic and Health Survey in Peru. Variables of interest were the PHQ-9 and demographic characteristics (sex, age group, level of education, socioeconomic status, marital status, and area of residence). Factor structure was evaluated by standard confirmatory factor analysis (CFA), and measurement invariance by multi-group CFA, using standard goodness-of-fit indices criteria for interpreting results from both CFAs. Analysis of the internal consistency (α and ω) was also pursued. RESULTS: Data from 30,449 study participants were analyzed, 56.7% were women, average age was 40.5 years (standard deviation (SD) = 16.3), 65.9% lived in urban areas, 74.6% were married, and had 9 years of education on average (SD = 4.6). From standard CFA, a one-dimensional model presented the best fit (CFI = 0.936; RMSEA = 0.089; SRMR = 0.039). From multi-group CFA, all progressively restricted models had ΔCFI<0.01 across almost all groups by demographic characteristics. PHQ-9 reliability was optimal (α = ω = 0.87). CONCLUSIONS: The evidence presents support for the one-dimensional model and measurement invariance of the PHQ-9 measure, allowing for reliable comparisons between sex, age groups, education level, socioeconomic status, marital status, and residence area, and recommends its use within the Peruvian population.
