Which of the following is an example of a regressive behavior in children diagnosed with PTSD?

Bedwetting is indeed an example of regressive behavior in children diagnosed with PTSD. Regression refers to a return to earlier or less mature forms of behavior that one had previously outgrown. In children, this can manifest in several ways, including the return of behaviors typical of an earlier developmental stage.

In the case of PTSD, children may experience emotional distress that leads to their reverted behaviors as a coping mechanism. Bedwetting, in particular, is considered a significant indicator because it is usually a behavior that children outgrow as they develop greater bladder control. When a child with PTSD regresses to bedwetting, it often highlights the psychological turmoil they are experiencing, possibly linked to their trauma, as they seek comfort in behaviors that once provided security.

The other behaviors listed, such as refusal to engage in social activities, excessive playing with toys, or talking back to adults, can be manifestations of various emotional or behavioral issues, but they do not specifically signify regression in the same way. For instance, avoiding social activities may reflect anxiety or a desire for avoidance rather than a return to earlier developmental behavior. Playing excessively may indicate a coping mechanism rather than regression. Similarly, talking back can reflect defiance or struggles with authority rather than an earlier developmental stage.
