Sleep onset insomnia is a common problem of college students. Buckelew, DeGood, et al. (2009, 2013) found evidence for an EEG disregulation (or impaired neuroflexibility) model for poor sleepers with persistent delayed sleep onset. Students who were good sleepers demonstrated better alpha activation/deactivation control compared with poor sleepers. The current pilot study was designed to assess if poor sleepers could improve voluntary EEG activation/deactivation control, utilizing alpha feedback (both enhance and suppress) during neurofeedback conditions. Poor sleepers were identified as students who attained a score above a 5 on the Pittsburgh Sleep Quality Inventory (PSQI) and reported chronic trouble sleeping (taking 30 min or longer to go to sleep for at least one year). Eight students (3 male, 5 female) participated in a six-week sleep enhancement program including basic insomnia education, sleep hygiene, relaxation, and stimulus control training. Additionally, these students also participated in six sessions of two trials of alpha enhancement and suppression with auditory and visual feedback. EEG was recorded from a Cz placement. The PSQI was completed before and at the end of training. A comparison group of 7 other poor sleepers also completed the PSQI at 6-week intervals, but did not participate in any treatment. There was a significant between group across time interaction on Sleep Quality scores, F (1, 13) = 7. 186, p = .02, with students who participated in the training program reporting improved sleep and the comparison students reporting poorer sleep across time. For the treatment group a repeated measures ANOVA with alpha control as the dependent variable, revealed that alpha control significantly improved across training from Session 1 (time 1) until after training (Session 6, time 2). Thus, the poor sleepers in the treatment group reported both improved sleep and demonstrated better alpha control (enhanced neuroflexibility) at the end of training. This preliminary study provides support for neurofeedback as an adjunct to a comprehensive sleep-training program. Seemingly, neuroflexibility impairments, which we believe are associated with poor sleep regulation, can respond to neurofeedback treatment. Future studies should include a larger sample size and random assignment to an experimental and a placebo controlled condition. Keywords * Sleep onset insomnia * Sleep hygiene * EEG biofeedback
