Article: Cognitive-behavioral therapy for insomnia improves attentional function in fibromyalgia syndrome: a pilot, randomized controlled trial.
[show abstract] [hide abstract]
ABSTRACT: This pilot, randomized controlled trial analyzed the effects of a cognitive behavioral therapy (CBT, n = 20) for insomnia vs a sleep hygiene (SH, n = 20) program on the three attentional networks (alertness, orienting, and executive function) and other additional outcome measures (sleep, pain, depression, anxiety, and daily functioning) of fibromyalgia patients. The CBT group showed significant improvement in alertness (F(1, 28) = 11.84, p = .0018), executive functioning (F(1, 28) = 15.76, p = .00059), sleep quality ( F(1, 38) = 6.33, p = .016), and a trend to improvement in daily functioning (p > .06), as compared with the SH group. The improvement in executive functioning was significantly related to the changes in sleep (r = 0.40, p = .026). A CBT for insomnia represents a useful intervention in fibromyalgia patients not only regarding sleep disturbance but also attentional dysfunction and probably daily functioning.Journal of Health Psychology 02/2011; 16(5):770-82. · 1.22 Impact Factor -
Article: Affective and Personality Characteristics in Function of Nightmare Prevalence, Nightmare Distress, and Interference Due to Nightmares.
[show abstract] [hide abstract]
ABSTRACT: This study analyzes the relationships among nightmare frequency, nightmare distress, and interference due to nightmares, sleep quality, psychopathology (anxiety and depression), and personality (neuroticism, psychoticism, and boundaries). The nightmare parameters were evaluated with the Nightmare Frequency Questionnaire (B. Krakow et al., 2000; see also record 2000-16731-002), the Nightmare Distress Questionnaire (K. Belicki, 1992b; see also record 1993-08389-001), and the Nightmare Effects Survey (Krakow et al., 2000). The sample was composed of 147 healthy students. The results demonstrated that the 2 measurements of distress (subjective distress associated with nightmares and, especially, deterioration of psychosocial functioning) were the dimensions that best related to the variables studied, although the relationships were modulated by nightmare frequency. The parameter of nightmare frequency was found to be useful as an indicator of certain personality characteristics rather than psychological perturbation. Having nightmares on a weekly basis was strongly associated with depressed mood. The knowledge about these relations is relevant not only theoretically but also as a practical guide.
