The transdiagnostic model allows explaining and developing treatments based on the etiology and maintenance factors of comorbid psychopathologies; however, the relationships between its explanatory variables still require investigation. The purpose of this paper was to develop a structural model that includes these transdiagnostic variables: positive and negative affect, intolerance to uncertainty and anxiety sensitivity, in emotional problems such as anxiety and depression. Quantitative research was carried out with an explanatory cross-sectional design in which a structural network of relationships between constructs was defined using a diagram of paths and structural equations. 486 Colombians between the ages of 20 and 40 were intentionally randomly sampled. The following instruments were used to assess the fitting of the model: Positive and Negative Affect Scale (PA-NAS), Anxiety Sensitivity Index-3 (ASI-3), Intolerance of Uncertainty Scale (IUS), Beck Anxiety Inventory (BAI) and Beck Depression Inventory, second edition, Spanish version (BDI-II). The results showed significant correlations between transdiagnostic and symptomatic variables (depression and anxiety symptoms), using an adjusted model that explained the predictive capacity of anxiety sensitivity with anxiety symptoms, and intolerance of uncertainty with depression symptoms, both transdiagnostic variables associated with positive and negative affect as predictors of anxious and depressive emotional symptoms (R 2 = .74).

Nonverbal cues have been fundamental to the survival of our species, and they remain a critical aspect of communication. Starting at the moment of birth, children's facial expressions and body gestures reflecting pleasure and discomfort elicit different responses from caregivers, which can shape the trajectory of child development. Although early expressions of emotion are universal, socialization of the intensity of expressions begins in infancy and may be influenced by the place the child is born, family characteristics, and other factors. The aim of this study is to describe the differences in the intensity of emotional expression between Chilean and U.S. infants at approximately 1 year of age. Infants' emotional expressions of pleasure and discomfort are described in terms of total intensity and specific facial and corporal intensities. The expressions were assessed by videotaping and coding the children's behaviours during a sequence of pleasurable and displeasing activities. The analyses revealed that the U.S. children expressed pleasure and discomfort with greater intensity compared with the Chilean children, specifically through corporal expressions. Highlights This study explores differences in the intensity of emotional expression of Chilean and U.S. infants around 1 year of age. Assessment involved a sequence of videotaped tasks and showed U.S. infants expressed pleasure and discomfort with higher intensity than Chilean infants. Differences between both samples at 1 year reveal the possibility that cultural emotion socialization shapes emotional expressions very early in development.

ResumenEl trabajo policial es considerado una profesión de alto estrés ya que estos funcionarios están expuestos a situaciones violentas, nocivas y exigentes. En la condición de estrés excesivo hay manifestaciones a nivel físico y psicológico que afectan directamente su quehacer policial y su vida personal y familiar. Esta investigación pretendió conocer el estado de salud fí-sica y mental de una muestra de policías, vinculados a la Escuela de Investigación Criminal (ESINC) y su relación con variables demográficas, grado policial, especialización y percepción que tienen sobre las ór-denes impartidas. Se realizó un estudio descriptivo correlacional de corte transversal. Los participantes fueron seleccionados mediante un muestreo probabilístico estratificado con afijación proporcional. Los resultados muestran que quienes estiman que las ór-denes impartidas en la Escuela son apresuradas, manifiestan dolor en alguna parte del cuerpo, notifican menos vitalidad, se sienten más agotados, cansados, desanimados y tristes. Quienes consideran que el trabajo es excesivo, indican que el dolor corporal les ha dificultado su trabajo habitual (incluido su trabajo fuera de casa y las tareas domésticas).Palabras clave: policía, estrés, salud física, salud mental.
