Abstract Recently, we undertook a case series study and found that behavior therapy for insomnia was effective as plied in the clinic setting and that the findings were similar to those in the "clinical trial" literature. In the present study, we evaluate a second set of case series data to assess (1) the replicability of our original findings, (2) if our treatment outcomes are statistically comparable to those in the literature, and (3) if medical and psychiatric morbidity influence treatment outcome. It was found that patients who completed four or more sessions of cognitive behavioral therapy for insomnia (CBT) were, on average, 33\% improved. This average corresponded to a 56\% reduction in wake time after sleep onset, a 34\% reduction in sleep latency, a 29\% increase in total sleep time, and a 13\% decrease in number of awakenings per night. These findings are not significantly different from those reported in literature for both CBT and pharmacotherapy interventions. Medical and psychiatric comorbidity did not influence treatment outcome.
