Which of the following is a sign of potential abuse or neglect in children?

Sudden changes in behavior or performance can be significant indicators of potential abuse or neglect in children. This response can manifest in various ways, such as withdrawing from social interactions, declining academic performance, or displaying increased aggression or anxiety. These abrupt changes often suggest that the child is experiencing distress or trauma, which may be linked to their home environment or relationship dynamics.

In contrast, increased sociability can be a normal part of a child's development and may not necessarily indicate any issues. Improved academic performance usually reflects positive changes in a child's life, which is not typically associated with abuse or neglect. Consistent punctuality is also generally considered a positive trait, suggesting reliability or stability in the child's routine. Consequently, these other options do not provide the same level of concern regarding potential indicators of abuse or neglect as the observed behavioral changes do.
