A 37-year-old White man presents to the psychiatric-mental health nurse practitioner (PMHNP) with suspected conversion disorder. According to Erikson, the development of conversion disorder is associated with failure to resolve which psychosocial developmental stage?

Choice A reason: Industry vs. inferiority (ages 6–12) relates to competence and skill mastery, not the emotional patterns leading to conversion disorder. Choice B reason: Initiative vs. guilt (ages 3–5) involves developing self-initiative; failure in this stage can result in inhibition, guilt, and somatic manifestations, which are characteristic of conversion disorder. Choice C reason: Identity vs. role confusion (ages 12–18) affects adolescent identity formation but is not directly associated with conversion disorder. Choice D reason: Intimacy vs. isolation (ages 18–35) pertains to forming close relationships and does not explain conversion disorder development.
