nonphysical abuse: a pattern of behavior in which one person deliberately and repeatedly subjects another to nonphysical acts that are detrimental to behavioral and affective functioning and overall mental well-being. Researchers have yet to formulate a universally agreed upon definition of the concept, but they have identified a variety of forms that emotional abuse may take, including verbal abuse; intimidation and terrorization; humiliation and degradation; exploitation; harassment; rejection and withholding of affection; isolation; and excessive control. Also called psychological abuse.
