  • Learned Nocebo Effects on Cutaneous Sensations of Pain and Itch

  • Influencing the Insulin System by Placebo Effects in Patients With Diabetes Type 2 and Healthy Controls

    Open AccessAleksandrina Skvortsova, Dieuwke S Veldhuijzen et al.ARTICLEPsychosomatic Medicine2023

    OBJECTIVE: The objective of this study was to investigate whether placebo effect induced by pharmacological conditioning with intranasal insulin can affect glucose, insulin, C-peptide, hunger, and memory in patients with diabetes type 2 and healthy controls. METHODS: Placebo effect was induced by pharmacological conditioning. Thirty-two older patients (mean age = 68.3 years) with diabetes type 2 and age- and sex-matched thirty-two healthy older a…

  • Integrating Placebo Effects in General Practice

    Open AccessRosanne M Smits, Dieuwke S Veldhuijzen et al.ARTICLEFrontiers in Psychiatry2022

    Objectives: Placebo effects, beneficial treatment outcomes due to non-active treatment components, play an important role in the overall treatment response. To facilitate these beneficial effects it is important to explore the perspectives of health care professionals (HCPs) on the integration of placebo effects in clinical care. Three themes were investigated: knowledge about placebo effects and factors that contribute to these, frequency of pla…

  • Open- and Closed-Label Placebo and Nocebo Suggestions About a Sham Transdermal Patch

    Open AccessStefanie H Meeuwis, Henriët Van Middendorp et al.ARTICLEPsychosomatic Medicine2021

    OBJECTIVE: Placebo effects may occur when it is known that an inert substance is given (i.e., open-label placebo). It is not yet clear whether these effects are similar to concealed (i.e., closed-label) placebo effects for itch or whether nocebo effects can be induced under open-label conditions. METHODS: Healthy volunteers (n = 112) were randomized to an open-label (I) or closed-label (II) positive suggestions group, or an open-label (III) or cl…

  • Placebo Effects in the Neuroendocrine System

    Open AccessAleksandrina Skvortsova, Dieuwke S Veldhuijzen et al.ARTICLEPsychosomatic Medicine2020

    OBJECTIVE: There is evidence that placebo effects may influence hormone secretion. However, few studies have examined placebo effects in the endocrine system, including oxytocin placebo effects. We studied whether it is possible to trigger oxytocin placebo effects using a classical conditioning paradigm. METHODS: Ninety-nine women were assigned to a conditioned, control, or drug control group. In the two-phase conditioning paradigm, participants …

  • Antipruritic Placebo Effects by Conditioning H1-antihistamine

    Open AccessStefanie H Meeuwis, Henriët Van Middendorp et al.ARTICLEPsychosomatic Medicine2019

    OBJECTIVE: Allergic rhinitis symptoms can be reduced by behaviorally conditioning antihistamine. It is unclear whether these findings extend to histamine-induced itch or work when participants are informed about the conditioning procedure (open-label conditioning). The current study aims to investigate the efficacy of (open-label) antipruritic behavioral conditioning for histamine-induced itch. METHODS: Healthy participants (n = 92; 84% female) w…

  • Effects of Open- and Closed-Label Nocebo and Placebo Suggestions on Itch and Itch Expectations

    Open AccessStefanie H Meeuwis, Henriët Van Middendorp et al.ARTICLEFrontiers in Psychiatry2019

    Placebo and nocebo effects have been shown to influence subjective symptoms such as itch. These effects can be induced by influencing outcome expectations through, for example, combining the application of an inert substance (e.g., a cream) with verbal suggestions on the anticipated effects of this substance. Interestingly, placebo effects also occur when it is known that a treatment is inert (i.e., open-label placebo). However, no study to date …

  • Enhancing Placebo Effects in Somatic Symptoms Through Oxytocin

    Open AccessAleksandrina Skvortsova, Dieuwke S Veldhuijzen et al.ARTICLEPsychosomatic Medicine2018

    OBJECTIVE: Placebo effects relieve various somatic symptoms, but it is unclear how they can be enhanced to maximize positive treatment outcomes. Oxytocin administration may potentially enhance placebo effects, but few studies have been performed, and they have had conflicting findings. The study aim was to investigate the influence of positive verbal suggestions and oxytocin on treatment expectations and placebo effects for pain and itch. METHODS…
