Acute Suicidal Affective Disturbance Inventory lifetime (ASADI-L): Initial validation of a German version

Blog Article

A syndrome called Acute Suicidal Affective Disturbance (ASAD) has recently been proposed as a suicide specific diagnosis (1).The syndrome is characterized by a drastic increase in suicidal intent, social and self-alienation, as well as overarousal.A 28-item self-report measure, the Acute Suicidal Affective Disturbance Inventory Lifetime (ASADI-L), has been developed to assess the lifetime occurrence of ASAD symptoms.

This study aims to validate a German version of the ASADI-L and to replicate the unidimensional factor click here structure of the original version.The psychometric properties of the German version of the ASADI-L were examined in a non-clinical online sample of n1 = 300 participants, n2 = 837 outpatients from a mental health research and treatment center and n3 = 148 outpatients from a treatment study on individuals diagnosed with Borderline Personality Disorder.A substantial proportion of all participants, including 23 % in Sample 1, 13.

26 % in Sample 2, and 86.49 % in Sample 3, reported having ever experienced a drastic increase in suicide intent during their lifetime.In addition, 20 % reported every single ASAD item on the ASAD-IL.

Confirmatory factor analysis showed an adequate model fit for the unidimensional model, with good internal consistency.Convergent validity was supported by significant correlations with measures of suicide-related constructs as well as symptoms of self-hatred and feelings of disgust as assessed in the Borderline Symptom List-23 (BSL-23).Future research should cashel tail bag focus on ASAD in longitudinal studies to deepen the understanding of the syndrome and to examine the predictive power of this suicide-specific diagnosis.
