Randomized Controlled Trial
Guided imagery in people with fibromyalgia: a randomized controlled trial of effects on pain, functional status and self-efficacy.
Studies on the effects of guided imagery in patients with fibromyalgia show varying results. This randomized controlled trial (n = 65) aims to give more insight into the effects on pain, functional status, and self-efficacy. ⋯ No effects of guided imagery could be established. Explanations for the diverging results between studies might be found in the content of the exercises, length of the intervention period, and background of participants.

Randomized Controlled Trial
The role of threat expectancy in attentional bias and thermal pain perception in healthy individuals.
The influence of threat expectancy upon attentional biases for pain-related information and pain thresholds was explored in healthy participants. Participants were randomized to receive either threatening (n = 32) or nonthreatening (n = 31) information regarding an upcoming computerized task assessing cold and heat pain thresholds. ⋯ No between-group differences were found in terms of cold and heat pain thresholds. These results show that the type of information participants receive can influence their attentional processes and emotional concerns.

Randomized Controlled Trial
Clown intervention to reduce preoperative anxiety in children and parents: a randomized controlled trial.
This study investigated whether a clown doctor intervention could reduce preoperative anxiety in children hospitalized for minor surgery and in their parents. A randomized controlled trial was conducted with 77 children and 119 parents: the clown group consisted of 52 children accompanied in the preoperating room by their parents (n = 89) and two clowns while the comparison group consisted of children accompanied by the parents only. The clown intervention significantly reduced the children's preoperative anxiety: children benefited from the clown's presence and showed better adjustment than children in the comparison group. Mothers in Comparison Group showed higher anxiety.

Randomized Controlled Trial
Massage on experimental pain in healthy females: a randomized controlled trial.
This randomized controlled study evaluated the effect of massage on affect, relaxation, and experimental pain induced by electrical stimulation. Participants were 96 healthy women (M age = 20.13 ± 5.93 years; 84.4% White) randomly assigned to a 15-minute no-treatment control, guided imagery, massage or massage plus guided imagery condition. ⋯ The two massage conditions generally reported decreased pain unpleasantness, lower unpleasant affect, maintenance of pleasant affect, and increased relaxation compared to the no-treatment condition. The results suggest that massage may alter immediate affective qualities in the context of pain.

Randomized Controlled Trial
Cognitive-behavioral therapy for insomnia improves attentional function in fibromyalgia syndrome: a pilot, randomized controlled trial.
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.
