Development and validation of the General attitude towards Medication Questionnaire (Gamq)
The newly developed GAMQ showed satisfactory psychometric properties in a variety of populations, although limitations should be considered. The GAMQ is the first scale to assess both positive and negative attitudes towards medication in general, providing indicators of Trust, Concerns, and Reluctance regarding medication. The scale may be an informative measure for predicting treatment outcomes and adherence, as well as placebo and nocebo effect…

Influencing the Insulin System by Placebo Effects in Patients With Diabetes Type 2 and Healthy Controls
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…
Effectiveness of Human-Supported and Self-Help eHealth Lifestyle Interventions for Patients With Cardiometabolic Risk Factors
OBJECTIVE: eHealth is a useful tool to deliver lifestyle interventions for patients with cardiometabolic diseases. However, there are inconsistent findings about whether these eHealth interventions should be supported by a human professional, or whether self-help interventions are equally effective. METHODS: Databases were searched between January 1995 and October 2021 for randomized controlled trials on cardiometabolic diseases (cardiovascular d…
EHealth to Improve Psychological Functioning and Self-Management of People With Chronic Kidney Disease
OBJECTIVE: Psychological distress is common among patients with chronic kidney disease and can interfere with disease self-management. We assessed the effectiveness of the personalized E-GOAL electronic health care pathway with screening and cognitive-behavioral therapy including self-management support, aimed to treat psychological distress and facilitate self-management among people with chronic kidney disease not on dialysis ( N = 121). METHOD…
The Personalized Priority and Progress Questionnaire (PPPQ)
The PPPQ proved to be a feasible and valid instrument. The PPPQ can be adapted to match diverse populations and could be a useful tool both in clinical practice (e.g., to identify priorities and tailor treatment) and clinical trials (e.g., to evaluate the effectiveness of personalized interventions)
Do individual psychological characteristics predict induction and generalization of nocebo and placebo effects on pain and itch
The tested psychological characteristics may not play an important role in the induction and generalization of nocebo and placebo effects in healthy individuals. However, firm conclusions cannot be drawn with the current sample. Future studies should validate findings in larger and more diverse samples
Integrating Placebo Effects in General Practice
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…
On the relationship between valence and arousal in samples across the globe
Affect is involved in many psychological phenomena, but a descriptive structure, long sought, has been elusive. Valence and arousal are fundamental, and a key question-the focus of the present study-is the relationship between them. Valence is sometimes thought to be independent of arousal, but, in some studies (representing too few societies in the world) arousal was found to vary with valence. One common finding is that arousal is lowest at neu…
Support for a Covid-19 vaccine mandate in the face of safety concerns and political affiliations
COVID-19 vaccine development has been widely awaited, but concerns around acceptance and political polarisation prevail. We sought to determine the willingness of Australians to take a (then prospective) COVID-19 vaccine, compared with their previously recorded opinions about other vaccines. We also sought to determine reasons for hesitancy, levels of support for possible government mandates, and the political basis of support. We surveyed 1200 A…
Does Materialism Hinder Relational Well-Being? The Role of Culture and Social Motives
Spatial knowledge acquired from first-person and dynamic map perspectives
As we become familiar with an environment through navigation and map study, spatial information is encoded into a mental representation of space. It is currently unclear to what degree mental representations of space are determined by the perspective in which spatial information is acquired. The overlapping model of spatial knowledge argues that spatial information is encoded into a common spatial representation independent of learning perspectiv…
Open- and Closed-Label Placebo and Nocebo Suggestions About a Sham Transdermal Patch
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…
Detecting and Treating Psychosocial and Lifestyle-Related Difficulties in Chronic Disease
Many patients with lifestyle-related chronic diseases find it difficult to adhere to a healthy and active lifestyle, often due to psychosocial difficulties. The aim of the current study was to develop an eHealth care pathway aimed at detecting and treating psychosocial and lifestyle-related difficulties that fits the needs and preferences of individual patients across various lifestyle-related chronic diseases. Each intervention component was dev…
Giving to Animal Charities
Growing public concern for the welfare of animals is reflected in an increase in the number of animal charities around the world. However, little is known about the individuals who donate to these organizations. In this study, we examine relations between individual differences in personal values and sociodemographic characteristics and the decision to donate to animal charities. We do this in samples from nine different countries: the USA, Canad…
Placebo Effects in the Neuroendocrine System
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 …
Majority acceptance of vaccination and mandates across the political spectrum in Australia
The Australian government has recently introduced some of the strictest vaccination mandates in the world. In light of international studies warning that public opposition to vaccination mandates could undermine public consensus about the value of vaccination, we conduct an original study of more than 1000 Australians on attitudes towards both vaccination and mandates. We find that, in contrast to similar studies in the United States and the Unit…
Antipruritic Placebo Effects by Conditioning H1-antihistamine
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
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 …
The Use of Expectancy and Empathy When Communicating With Patients With Advanced Breast Cancer; an Observational Study of Clinician–Patient Consultations
Background: Information provision about prognosis, treatments, and side-effects is important in advanced cancer, yet also associated with impaired patient well-being. To counter potential detrimental effects, communication strategies based on placebo and nocebo effect mechanisms might be promising to apply in daily practice. This study aimed to provide more insight into how often and how oncologists use expectancy and empathy expressions in consu…
Enhancing Placebo Effects in Somatic Symptoms Through Oxytocin
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…

Why do Highly Qualified Women (Still) Earn Less? Gender Differences in Long-Term Predictors of Career Success
Our study investigated gender differences in the long-term effects of education, work experience, agentic personality traits, and number of children on career success (i.e., salary) in medicine. German male and female students ( N = 99) were surveyed at a German medical school (T1) and 15 years later (T2). Women interrupted their careers for longer than men ( d = .92). Men had a substantially higher income at T2 ( d = 1.07). Career interruptions,…
