Tóm tắt	The DES is a 28-item self-report questionnaire designed to measure the frequency and severity of dissociative symptoms, including depersonalization (feeling detached from one's body), derealization (feeling the world is unreal), amnesia, absorption (intense focus), and identity confusion. Developed by Bernstein and Putnam in 1986, it is the most widely used dissociation screening instrument in clinical and research settings. The DES helps identify dissociative disorders (dissociative identity disorder, other specified dissociative disorder), trauma-related dissociation, and dissociative symptoms in other psychiatric conditions.	The PANSS is a 30-item clinician-administered scale designed to measure the presence and severity of positive symptoms (delusions, hallucinations, disorganization), negative symptoms (affective flattening, alogia, avolition), and general psychopathology in schizophrenia and related psychotic disorders. Developed by Kay, Fiszbein, and Opler in 1987, the PANSS has become the standard rating scale in schizophrenia research, antipsychotic medication trials, and clinical monitoring. It provides comprehensive assessment across three symptom domains and yields a total score reflecting overall disease severity.
