title: Similarity of monozygotic and dizygotic child twins in level and lability of subclinically depressed mood.
abstract: Twenty child monozygotic twin-pairs were compared to 21 child dizygotic twin-pairs on similarity of level and lability of subclinically depressed mood. Mood was assessed by self, parent, and teacher ratings. Estimates of genetic variance were statistically significant for about half of the measures of both level and lability of depression.
