Which of the following best defines psychosis?

The definition of psychosis is best captured by the idea of a condition characterized by a distorted perception of reality. This is a fundamental aspect of psychosis, as individuals experiencing it often have significant disruptions in their thoughts, perceptions, and emotional responses. This can result in hallucinations (experiencing things that are not present, such as hearing voices) or delusions (firmly held false beliefs). These distortions can severely impact an individual’s ability to function in everyday life and often necessitate clinical intervention.

The other options do not accurately reflect the nature of psychosis. A mild mood disorder refers to conditions like mild depression or anxiety, which do not encompass the severe distortions characteristic of psychosis. Anxiety disorders primarily involve excessive worry or fear but do not typically include the loss of contact with reality found in psychosis. Similarly, PTSD (Post-Traumatic Stress Disorder) involves trauma-related symptoms such as flashbacks and avoidance behaviors, but it is not synonymous with the distorted perceptions seen in psychosis. Thus, option B is the most accurate definition in this context.
