P rofessionals concerned about maltreatment of children have focused on child physical and sexual abuse, paying less attention to child neglect (Wolock & Horowitz, 1984). There are several reasons why neglect has not received the attention it deserves (Dubowitz, 1994). First, the typically vague definitions of neglect make it an amorphous phenomenon (Greenbaum et al., 2008). Many professionals are understandably unclear about what constitutes neglect, how to identify neglect, and what course of action is appropriate and effective. Second, the strong association between child neglect and poverty (Giovannoni & Becerra, 1979) often evokes a sense of hopelessness among professionals, deterring them from becoming involved in the complex issues underpinning neglect situations. Thirdly, neglect does not evoke the horror and outrage of abuse. However, more than half of the reports for child maltreatment made in the United States each year are for neglect, and the morbidity and mortality associated with neglect are as severe as with abuse (e.g., Dong et al., 2004; Dubowitz, 2007; Teicher et al., 2004). This chapter focuses on one major form of neglect-neglect of children's health care. The chapter addresses the following: (1) definitional issues concerning neglected health care, (2) incidence, (3) etiology, (4) major manifestations, and (5) general principles for evaluation and (6) for intervention. Legal aspects of neglect of children's health care are discussed in Chapter 22.
