Psychosis is defined as a severe disruption in reality perception characterized by delusions and/or hallucinations (West, 2013). It is a common shared symptom of various disorders, including psychotic and non-psychotic disorders and neurologic and medical conditions (Arciniegas, 2015).

Psychotic disorders are severe mental illnesses that affect a person’s thinking, feelings, and behavior, such as hallucinations, delusions, disorganized thinking, and motor behavior (Tampi et al., 2019).

Purging behaviors are compensatory behaviors used by eating disorder patients, in which they forcibly eject food from their bodies in an effort to regulate their weight and/or physical appearance (Wade, 2017). Self-induced vomiting is the most common purging behavior (Neale & Hudson, 2020).
