Psychometric network analysis of the Patient Health Questionnaire-4 (PHQ-4) in Paraguayan general population.

BACKGROUND: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. OBJECTIVE: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. METHODS: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. RESULTS: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they were always replicated within the empirical dimension. The unidimensional structure has shown evidence of configural invariance; therefore, the network structure functioned equally among the different sex groups. CONCLUSION: The PHQ-4 presented optimal preliminary evidence of validity based on its internal structure, reliability, and invariance between sexes. Therefore, it may be useful as an accurate and brief measure of anxiety and depressive symptoms in the Paraguayan context.

Pandemic Grief and Suicidal Ideation in Latin American Countries: A Network Analysis.

This study aimed to characterize the network structure of pandemic grief symptoms and suicidal ideation in 2174 people from eight Latin American countries. Pandemic grief and suicidal ideation were measured using the Pandemic Grief Scale and a single item, respectively. Network analysis provides an in-depth characterization of symptom-symptom interactions within mental disorders. The results indicated that, "desire to die," "apathy" and "absence of sense of life" are the most central symptoms in a pandemic grief symptom network; therefore, these symptoms could be focal elements for preventive and treatment efforts. Suicidal ideation, the wish to die, and the absence of meaning in life had the strongest relationship. In general, the network structure did not differ among the participating countries. It identifies specific symptoms within the network that may increase the likelihood of their co-occurrence and is useful at the therapeutic level.

Fear of monkeypox and intention to vaccinate against monkeypox: a network analysis

Introduction: The presence of fear of an infectious disease triggers psychological factors associated with perceived behavioral control over vaccination acceptance, subjective norms of vaccination acceptance, attitudes toward vaccination acceptance, and perceived infectiousness from disease. Objective: The study evaluated how symptoms of fear of Monkeypox specifically relate to intention to be vaccinated against Monkeypox in a sample of 506 Peruvian individuals with a mean age of 27.11 years (SD = 9.77). Methods: Participants responded to the Monkeypox Fear Scale (MFS) and a single item of Intention to be vaccinated against Monkeypox. Using network analysis, central fear symptoms and associations between symptoms and intention to vaccinate were identified. Results: The results suggest that the node with the highest centrality was item 5 of the MFS. Regarding the connection between the intention to be vaccinated and the MFS items, a direct relationship was observed with item 1 and an inverse relationship with item 6. In addition, the relationship between these MFS items and intention to vaccinate is higher in men compared to women. While it would be expected that a greater presence of symptoms of fear of Monkeypox could lead people to have a greater intention to be vaccinated against the disease, the results could lead other researchers to generate evidence to explain this relationship in other Latin American countries. Discussion: The evidence is useful for developing policies that favor vaccination against Monkeypox in Peru and other Latin American countries.

Introducción: La presencia del miedo a una enfermedad infecciosa desencadena factores psicológicos asociados con el control conductual percibido sobre la aceptación de la vacunación, normas subjetivas de aceptación de la vacunación, actitudes hacia la aceptación de la vacunación y la percepción de la infectividad de la enfermedad. Objetivo: El estudio evaluó cómo los síntomas del miedo a la viruela del mono se relacionan específicamente con la intención de ser vacunado contra la viruela del mono en una muestra de 506 individuos peruanos con una edad promedio de 27,11 años (DE = 9,77). Métodos: Los participantes respondieron a la Escala de Miedo a la Viruela del Mono (MFS) y a un solo ítem de Intención de ser vacunado contra la viruela del mono. Utilizando análisis de redes, se identificaron los síntomas centrales del miedo y las asociaciones entre los síntomas y la intención de vacunarse. Resultados: Los resultados sugieren que el nodo con mayor centralidad fue el ítem 5 de la MFS. En cuanto a la conexión entre la intención de ser vacunado y los ítems de la MFS, se observó una relación directa con el ítem 1 y una relación inversa con el ítem 6. Además, la relación entre estos ítems de la MFS y la intención de vacunarse es mayor en hombres en comparación con mujeres. Si bien se esperaría que una mayor presencia de síntomas de miedo a la viruela del mono llevara a las personas a tener una mayor intención de ser vacunadas contra la enfermedad, los resultados podrían llevar a otros investigadores a generar evidencia para explicar esta relación en otros países de América Latina. Discusión: La evidencia es útil para desarrollar políticas que favorezcan la vacunación contra la viruela del mono en Perú y otros países de América Latina.
