The findings revealed significant predictive relationships between personality disorders and death anxiety.

Translating and validating the Ghosting Questionnaire into Arabic: results from classical test theory and item response theory analyses : Short title: the arabic version of the Ghosting Questionnaire.

Background: Ghosting refers to the sudden cessation of communication in interpersonal relationships. Ghosting has gained attention as a phenomenon commonly encountered in the context of digital communication. Earlier studies on ghosting mostly focused on Western societies while, in Arab societies, research into this practice has yet to be initiated.

The translation and validation of the surgical anxiety questionnaire into the modern standard Arabic language: results from classical test theory and item response theory analyses.

Background: Preoperative anxiety is commonly found in patients who are waiting for surgery and can lead to negative surgical outcomes. Understanding the sources of surgical anxiety allows healthcare providers to identify at-risk patients and implement psychosocial interventions such as counseling, relaxation techniques, and cognitive‒behavioral therapy to minimize anxiety. Few comprehensive psychiatric measures are available to assess preoperative anxiety in Arabic.

How accurately can supervised machine learning model predict a targeted psychiatric disorder?

Background: Hoarding disorder (HD) is characterized by a compulsion to collect belongings, and to experience significant distress when parting from them. HD is often misdiagnosed for several reasons. These include patient and family lack of recognition that it is a psychiatric disorder and professionals' lack of relevant expertise with it.
