Psycho-behavioral characteristics of children with vocal nodules: WPBIC ratings.

The parents of 30 children referred to speech pathology because of vocal nodules completed the Walker Problem Behavior Identification Checklist (WPBIC) on their children. These checklist responses were then compared to those from the parents of a matched, vocally normal, control group. The nodule children had significantly higher scores on the scales for acting out, distractibility, disturbed peer relations, and immature behaviors. The implications of these results for nodule formation and intervention are discussed.
