Diagnosis of hemophobia is based on a psychological evaluation, which is a structured interview with a mental health professional that provides information to assess the individual's behavior, personality, thought processes, and cognitive abilities, and subsequently, identify any disturbances.
Currently, the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) differentiates phobias into three groups: agoraphobia, or the fear of public places; social phobia, or the fear of social situations and interactions; and specific phobias, which are an irrational fear of an object or situation. In turn, specific phobias are subdivided into five categories, including fear of animals (e.g., spiders, snakes, dogs), fear of the natural environment (e.g., heights, storms, darkness), fear of blood and invasive medical procedures (e.g., blood, needles, injections), situational fears (e.g., elevators, flying); and finally, fears that do not fall into the previous categories.
According to the DSM-V, the criteria for the diagnosis of a phobia involves having an unreasonable fear or anxiety about a specific object or situation that lasts for at least 6 months and cannot be better explained by any other condition or substance. The fear or anxiety must be out of proportion to the actual danger posed by the situation and must result in clinically significant distress or severely affect the individual’s personal, social, or occupational activities.
