This study aims to investigate the effectiveness of cognitive-behavioral therapy for insomnia (CBT-I) on emotional regulation and dysfunctional sleep beliefs among insomniac patients. Objectives: Human body needs an adequate amount of night’s sleep after a long day to regain its power.
Regardless of severity of sleep disturbance, sleep-related bias may affect subjective feelings of wakefulness and objective levels of alertness (e.g., one who believes they are not obtaining sufficient sleep may act accordingly).
Dysfunctional beliefs about sleep correlate with RT through 8000ms delay, eventually predicting RT. There is a diminishing association found between insomnia severity and RT during inter-stimulus delay times (>6000ms). A regression was calculated to predict reaction time at 7000ms delay based on the DBAS (F(1,151) = 2.51, p =. DBAS was correlated with PVT RT for delay times of 2000ms r(162) =. ISI was correlated with PVT RT for inter-stimulus interval delay times of 1000ms r(162) =. Inclusion criteria: right-handed adults exclusion criteria: history of brain injury, seizure disorder, or vision impairment. This study focuses on the relationship between dysfunctional sleep-related cognitions (Dysfunctional Beliefs and Attitudes About Sleep Scale ), insomnia severity (Insomnia Severity Index ), and sleepiness (Epworth Sleepiness Scale ) and their association to PVT RT.ġ62 participants were recruited from East Carolina University. The Perceptual Vigilance Task (PVT), a measure of reaction time (RT) used to assess alertness is commonly used in sleep research. Poor sleep quality has adverse effects ranging from decreased focus to increased work-related injuries.
