      <p><i>Background - </i>Fear of pain is highly correlated with pain report and physiological measures of arousal when pain is inflicted. The Fear of Pain Questionnaire III (FPQ-III) and The Fear of Pain Questionnaire Short Form (FPQ-SF) are self-report inventories developed for assessment of fear of pain (FOP). A previous study assessed the fit of the FPQ-III and the FPQ-SF in a Norwegian non-clinical ...

      Vambheim, Sara Magelssen; Lyby, Peter Solvoll; Aslaksen, Per M.; Flaten, Magne; Åsli, Ole; Martinussen, Laila Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-08)
      <i>Background</i>: The Fear of Pain Questionnaire-III (FPQ-III) is a widely used instrument to assess the fear of pain (FOP) in clinical and nonclinical samples. The FPQ-III has 30 items and is divided into three subscales: Severe Pain, Minor Pain and Medical Pain. Due to findings of poor fit of the original three-factor FPQ-III model, the Fear of Pain Questionnaire-Short Form ...
    • Language of motivation and emotion in an internet support group for smoking cessation: Explorative use of automated content analysis to measure regulatory focus 

      Johnsen, Jan-Are Kolset; Vambheim, Sara Magelssen; Wynn, Rolf; Wangberg, Silje C (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      The present study describes a novel approach to the identification of the motivational processes in text data extracted from an Internet support group (ISG) for smoking cessation. Based on the previous findings that a “prevention” focus might be more relevant for maintaining behavior change, it was hypothesized that 1) language use (ie, the use of emotional words) signaling a “promotion” focus would ...
    • Relaxation techniques as an intervention for chronic pain: A systematic review of randomized controlled trials 

      Vambheim, Sara Magelssen; Kyllo, Tonje; Hegland, Sanne; Bystad, Martin Kragnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-20)
      Chronic pain increases the risk of sleep disturbances, depression and disability. Even though medical treatments have limited value, the use of prescription-based analgesics have increased over the recent years. It is therefore important to evaluate the effect of non-pharmacological treatments. A systematic search for studies evaluating the effect of relaxation techniques on chronic pain was ...
    • Sex differences in fear of pain: item-level analysis of the Fear of Pain Questionnaire III 

      Vambheim, Sara Magelssen; Øien, Roald A (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-07)
      Objectives: This study aimed to investigate sex differences in fear of pain (FOP) measured by the Fear of Pain Questionnaire III (FPQ-III) in a nonclinical sample. The FPQ-III is a selfreport inventory measuring FOP, with 30 items, divided into three subscales: Severe, Minor and Medical Pain. <p> Methods: A total of 185 subjects participated (49.7% females) in this study. Sex differences on ...
    • Sex differences in pain, fear of pain and placebo analgesia 

      Vambheim, Sara Magelssen (Doctoral thesis; Doktorgradsavhandling, 2018-11-13)
      The hypothesis that males are more responsive to placebo treatment than females was tested experimentally in this thesis. The hypothesis was confirmed and the results showed that the sex difference was related to a difference in males’ and females’ stress response after placebo treatment. Placebo responses on pain unpleasantness and the P2 component was found in males, but not in females. The ...
    • Sex-Differences in Children Referred for Assessment: An Exploratory Analysis of the Autism Mental Status Exam (AMSE) 

      Øien, Roald A; Vambheim, Sara Magelssen; Hart, Logan; Nordahl-Hansen, Anders; Erickson, Craig; Wink, Logan; Eisemann, Martin; Shic, Frederick; Volkmar, Fred R.; Grodberg, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-08)
      The autism mental status exam is an eight-item observational assessment that structures the way we observe and document signs and symptoms of ASD. Investigations of test performance indicate strong sensitivity and specificity using gold-standard assessment as reference standard. This study aims to explore potential sex differences in AMSE test performance and observations of 123 children referred ...
    • A systematic review of sex differences in the placebo and the nocebo effect 

      Vambheim, Sara Magelssen; Flaten, Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-31)
      Objectives: The present review investigated whether there are systematic sex differences in the placebo and the nocebo effect. <br>Methods: A literature search was conducted in multiple electronic databases. Studies were included if the study compared a group or condition where a placebo was administered to a natural history group or similar cohort. <br>Results: Eighteen studies were identified ...
