| dc.description.abstract | Background: Suicide is a significant public health concern, and several psychological variables, such as childhood trauma, have been studied as risk factors, but this link remains unclear. The study aims to examine the association between childhood trauma (i.e., physical and emotional abuse/neglect and sexual abuse) and suicide, as well as to analyze the mediating role of alexithymia and mental health (i.e., depression and anxiety) in this relationship. Methods: A total of 75 individuals with dual diagnosis (on average, 44.15 years old, SD = 12.15; 82.7% males) completed four questionnaires: Childhood Trauma Questionnaire, Toronto Alexithymia Scale, Symptoms Assessment-45, and Paykel Suicide Scale. Structural equation modeling was performed to examine the mediating role of alexithymia and mental health in the relationship between childhood trauma and suicidal behavior. Results: Both alexithymia and mental health problems mediate the relationship between childhood trauma and suicidal behavior. Conclusions: This finding underscores the importance of screening for and addressing alexithymia and mental health in clinical practice, especially in suicide-prevention interventions. | en |
| dc.description.abstract | Antecedentes: El suicidio representa un importante problema de salud pública, y diversas variables psicológicas han sido estudiadas como factores de riesgo, entre ellas el trauma infantil; sin embargo, esta relación sigue siendo poco clara. El estudio tiene como objetivo examinar la asociación entre el trauma infantil (i.e., abuso físico y emocional, negligencia física y emocional, y abuso sexual) y el suicidio, así como analizar el papel mediador de la alexitimia y la salud mental en esta relación. Método: 75 personas con patología dual (la edad media fue de 44,15 años, DT = 12,15; 82,7% hombres) completaron cuatro cuestionarios: el Cuestionario de Trauma Infantil, la Escala de Alexitimia, el SA-45 y la Escala de Suicidio de Paykel. Se empleó un modelo de ecuaciones estructurales para examinar el papel mediador de la alexitimia y la salud mental en la relación entre trauma infantil y conducta suicida. Resultados: Tanto la alexitimia como los problemas de salud mental mediaron la relación entre el trauma infantil y la conducta suicida. Conclusiones: Estos hallazgos subrayan la importancia de evaluar y abordar la alexitimia y los problemas de salud mental en la práctica clínica, especialmente en las intervenciones dirigidas a la prevención del suicidio. | es |
