Which of the following is NOT one of the common prevalence rates in adults for psychological disorders?

The common prevalence rates for psychological disorders in adults provide essential insight into mental health trends. Schizophrenia is well-documented with a prevalence rate of approximately 1%, which reflects the rarity of this serious mental health condition. Eating disorders, while potentially more variable, commonly fall within a prevalence range of 1-6%, particularly considering conditions such as anorexia and bulimia.

Dissociative disorders, while often underreported, have a prevalence estimate around 1-3%, significantly lower than the stated 19% in the question. This figure likely overestimates the actual occurrence of these disorders in the general population.

The prevalence of personality disorders, however, is often cited as around 15-20%, with some estimates approaching 25% in certain populations. This figure makes option C, which states that personality disorders have a prevalence rate of 25%, misleading, as it aligns more closely with specific subsets or certain populations rather than the general adult population.

Therefore, the correct answer identifies a statement that exaggerates the prevalence rate of personality disorders compared to the established research in psychological literature. This method of distinguishing between common prevalence rates for these disorders is critical for understanding mental health and guiding potential treatment approaches.
