Randomized Controlled Trial
Parental anxiety and stress before pediatric anesthesia: a pilot study on the effectiveness of preoperative clown intervention.
As induction of pediatric anesthesia can elicit anxiety in children and parents alike, this study was aimed at evaluating the effectiveness of clown intervention in decreasing maternal anxiety and stress in the preoperative phase. Before anesthesia induction, 25 children were randomly assigned to clown intervention and 25 to a control group with a routine procedure. ⋯ Moreover, after clown intervention, older children's mothers significantly reduced the level of perceived stress. As clown intervention can positively influence maternal anxiety and stress in the preoperative period, its promotion in clinical-hospital environments is recommended.

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.
