into things that trigger a child's memory of the abuse through observation of the child's behavior when interacting with other adults or children A particular challenge arises where child protection professionals are assessing families where neglect is occurring. Neglect is a complex phenomenon without a universally-accepted definition and professionals cite difficulty in knowing which questions to ask to identify neglect. Younger children, children living in poverty, and children with more siblings are at increased risk of neglect. Prevention A support-group structure is needed to reinforce parenting skills and closely monitor the child's well-being. Visiting home nurse or social-worker visits are also required to observe and evaluate the progress of the child and the caretaking situation. The support-group structure and visiting home nurse or social-worker visits are not mutually exclusive. Many studies have demonstrated that the two measures must be coupled together for the best possible outcome. Studies show that if health and medical care personnel in a structured way ask parents about important psychosocial risk factors in connection with visiting pediatric primary care and, if necessary, offering the parent help may help prevent child maltreatment. Children's school programs regarding "good touch … bad touch" can provide children with a forum in which to role-play and learn to avoid potentially harmful scenarios. Pediatricians can help identify children at risk of maltreatment and intervene with the aid of a social worker or provide access to treatment that addresses potential risk factors such as maternal depression. Videoconferencing has also been used to diagnose child abuse in remote emergency departments and clinics. Unintended conception increases the risk of subsequent child abuse, and large family size increases the risk of child neglect. Thus, a comprehensive study for the National Academy of Sciences concluded that affordable contraceptive services should form the basis for child abuse prevention. "The starting point for effective child abuse programming is pregnancy planning," according to an analysis for US Surgeon General C. Everett Koop. Findings from research published in 2016 support the importance of family relationships in the trajectory of a child's life: family-targeted interventions are important for improving long-term health, particularly in communities that are socioeconomically disadvantaged. Resources for child-protection services are sometimes limited. According to Hosin (2007), "a considerable number of traumatized abused children do not gain access to protective child-protection strategies." Briere (1992) argues that only when "lower-level violence" of children ceases to be culturally tolerated will there be
