Deaf children are more susceptible than other children to abuse in home and institutional settings. Many helping professionals are unaware of the unique vulnerabilities and needs of the deaf; this lack of awareness limits the effectiveness of their services to that population. Laws and ethical standards mandate that social workers and others use communication methods that deaf clients can understand; however, many human service agencies rely on less than adequate means of communication in child abuse investigations and other procedures. Such ineffective intervention practices fail to protect a vulnerable population of children who literally cannot speak for themselves.
