In earlier studies that used conventional BLT, the presence of headaches was slightly lower, whereas insomnia and nausea were reported more often [ 68].
Black women characterized by greater ISE scores reported lower rates of insomnia [rs = -0.43, p < 0.0001].
Within the White ethnicity, women with greater ISE scores also reported lower rates of insomnia [rs = -0.18, p < 0.0001].
In other words, larger number of co-morbid problems was associated with slightly lower improvements in insomnia severity.
Lower rates of insomnia symptoms observed among Blacks might reflect a greater ability to regulate negative emotions about the sleep process.
It should be noted, however, that larger number of co-morbid problems was associated with slightly lower improvements in insomnia severity.
Individuals with higher levels of achievement motivation report fewer financial problems, while those focused on solving problems indicate lower levels of insomnia.
When analyzed by age group, patients aged 65 and older were found to report a significantly lower incidence of insomnia and headache than those patients aged <65 (Table 4).
The explanation for the lower rates of insomnia symptoms among Blacks formulated in our previous report pointed to appraisal research [ 5], which shows that Blacks use more positive reappraisal than do Whites [ 7, 8, 16].
While many objective studies in the U.S. have suggested that individuals of African ancestry have characteristically worse sleep patterns [ 1, 2], relative to those of European descent, the preponderance of evidence indicates lower rates of insomnia symptoms among the former.
