In this preliminary investigation sixteen latency-age children were compared with matched good sleep children from child psychiatric and general pediatric clinic populations. Parent and child reports support the existence of chronic childhood insomnia, occurring at a greater frequency in an emotionally disturbed population. Although parent-child agreement on insomnia symptoms tends to be high, there was poor agreement on other sleep-related symptoms.
During the year their insomnia began, chronic insomniacs experienced a greater number of stressful life events compared with previous or subsequent years and compared with good sleepers. In addition, among the life event categories assessed, insomniacs reported a greater number of undesirable events, particularly events related to losses and to ill health. They also had lifelong histories of more illnesses and somatic complaints, beginning with more childhood illnesses and more childhood problems related to eating and sleeping. During childhood, insomniacs reported more frequent discontent with their families, and prior to the onset of insomnia, they had less satisfying relationships with their parents as well as problems in other interpersonal relations and in their self-concepts. Currently, insomniacs felt considerably less satisfied with their lives, had lower self-concepts, and had greater difficulty with interpersonal relationships. Thus, stressful life events, mediated by certain predisposing factors of personal vulnerability, were found to be closely related to the onset of chronic insomnia.
To determine whether poor sleepers have a unique personality constellation significantly different from that of good sleepers, a sample of 162 emotionally disturbed adolescent poor sleepers was compared to a sample of 153 emotionally disturbed adolescent good sleepers on standardized personality instruments. Poor sleepers were found to have a high incidence of neurotic psychopathology with personality patterns characterized by depression, fearfulness, inhibition, anxiety, and rumination. In contrast, good sleepers showed quasi-healthy and/or characterological patterns. While this study does not resolve cause and effect relationships, it does establish a highly significant relationship between neuroticism and sleep disturbance for adolescent boys and girls, and also demonstrates a similarity of personality dynamics and patterns between adult and adolescent samples of patients with sleep disturbances.

A sample of 53 poor sleepers (N = 37 boys and 16 girls) and a matched sample of 53 good sleepers were selected from a national study of 831 white, emotionally disturbed adolescents in treatment. Psychotherapists' ratings on 552 variables were examined by comparing the endorsement rates of the two groups by means of a split-sample procedure. The results yielded 74 replicated characteristics that differentiate poor from good sleepers, a number of which are highly unique to each group. Poor sleepers are consistently higher on measures associated with neuroticism, whereas good sleepers are higher on measures associated with pseudo-normalcy or psychopathy. These results present further evidence that personality dynamics play a critical role in disturbed sleep. The authors suggest that a reorientation that integrates personality and physiological findings is necessary to advance our understanding and treatment effectiveness of persons with disturbed sleep.
