Stress, support, psychological states and sleep.
A stress-support model incorporating indicators of life events, social support and SCL-90 measures of psychological distress was hypothesized to affect both reported and objective (somnographic) sleep. To determine the effects of these antecedents on sleep among 69 mid-life women, two models were tested, using both partial correlations and path analysis. Of all the measures of life events and social support examined in this study only negative LEs and contacts with non-supportive persons were associated (positively) with psychological distress, differentially explaining between 9% and 19% of the variance in each of five SCL-90 subscales. Both negative life events and contacts with non-supportive persons influenced depression and the SCL-90 PST index, whereas only negative life events affected anxiety, phobic anxiety and paranoid ideation. Anxiety, depression and the PST index, as indicators of psychological distress, had direct inverse effects on reported sleep with significant adjusted R2 values ranging from 10% to 16%. The model did not hold for somnographic sleep. The factors which are likely to contribute to the absence of an observed relationship between psychological distress and somnographic sleep are discussed.

Sleep quality subtypes in midlife women.
Eighty-two midlife women (40-59 years) were classified as poor or good sleepers according to either self-reported sleep quality or a sleep efficiency index (SEI) criterion, for comparison of wakefulness, fragmentation and other somnographic sleep variables; as well as psychological (SCL-90) and somatic symptom distress. When classified solely by self-report, the good and poor sleeper groups did not differ on any somnographic variables but self-declared poor sleepers had higher psychological distress scores than good sleepers (p less than or equal to 0.01). When classified solely by the SEI criterion, the good and poor sleepers did not differ on psychological distress but, as expected, differed on various somnographic wakefulness as well as rapid eye movement and stage 2 sleep variables. Further analysis of four subgroups derived by combining objective and subjective, good and poor sleep scores indicated that 15% of this sample (n = 12) perceived but had no objective evidence of poor sleep, and this group scored highest in psychological distress. Only seven women perceived poor sleep in concert with demonstrating low SEI. They scored highest in menopausal symptoms but not in general psychological distress.
