A comparison of elective mutism and emotional disorders in children.

The case notes of 24 children diagnosed as elective mutes were compared with those of 24 matched controls with diagnosed emotional disorders. One-third of the elective mutes (but none of the controls) had experienced delayed development of speech or difficulties in articulation. All the elective mutes lived in two-parent families, but marital discord was noted in half the families in both groups. Compared with the controls, the mute children were more often described as 'anxious', 'depressed' and 'manipulative', and their mothers were characterised as 'over-protective', and tending to 'spoil' their children. Three unusual cases, of mutism at home, are described in detail. It is proposed that elective mutism is associated with particular personal and family characteristics and represents a condition different from any recognised emotional disorder.
