SUICIDÁLNÍ IDEACE LGBT+ OSOB: PSYCHOMETRICKÉ VLASTNOSTI ŠKÁLY SUICIDÁLNÍ IDEACE (SIDAS) NA ČESKÉM LGBT+ VZORKU.

Introduction: This study assessed the psychometric properties of Czech adaptation of the Suicidal Ideation Assessment Scale (SIDAS) developed to enable online administration and evaluates its use among LGBT+ people. Methods: Using confirmatory factor analysis, we examined factor structure and measurement invariance across LGBT+ subgroups within a sample consisting of 1 778 participants. Results: We found a consistent one-factor structure and partial measurement invariance, enabling comparisons. SIDAS showed strong convergent validity with loneliness, emotion dysregulation, stress, rumination, and life satisfaction. Discussion: The adapted SIDAS proves valuable for assessing suicidal ideation within the LGBT+ community and is suitable for online administration; as such, it may help guide and assess the effects of targeted interventions. Future research should explore temporal dynamics and additional variables for severity assessment. [ABSTRACT FROM AUTHOR]
