Positive social modeling attenuates nocebo side effects
BACKGROUND: Receiving negative instructions and observing another's adverse treatment-related experience can lead to worsened health outcomes via the nocebo effect. However, it is unknown whether the observation of a positive treatment-related experience can mitigate these effects. PURPOSE: To investigate whether a positive social modeling intervention can reduce nocebo side effects induced by instruction and social modeling. METHODS: Participant…
Instruction on the Scientific Method Provides (Some) Protection Against Illusions of Causality
People tend to overestimate the efficacy of an ineffective treatment when they experience the treatment and its supposed outcome co-occurring frequently. This is referred to as the outcome density effect. Here, we attempted to improve the accuracy of participants’ assessments of an ineffective treatment by instructing them about the scientific practice of comparing treatment effects against a relevant base-rate, i.e., when no treatment is deliver…
A test of pre-exposure spacing and multiple context pre-exposure on the mechanisms of latent inhibition of dental fear
It is hypothesized that spaced pre-exposure and pre-exposure in multiple contexts will increase the engagement of the mechanisms of expected relevance and attention and increase the latent inhibition of dental fear. It is expected that the findings will add to theory on fear learning and provide information to aid the design of future interventions that leverage latent inhibition to reduce dental phobia
A study protocol testing pre-exposure dose and compound pre-exposure on the mechanisms of latent inhibition of dental fear
The proposed study will test whether pre-exposure dose and compound stimulus presentation change expected relevance and attention to the pre-exposed stimulus, and thereby enhance latent inhibition of dental fear. If found, the results will add to our theoretical understanding of the latent inhibition of dental fear and inform future interventions for dental phobia prevention
Replication crisis and placebo studies
A growing body of cross-cultural survey research shows high percentages of clinicians report using placebos in clinical settings. One motivation for clinicians using placebos is to help patients by capitalising on the placebo effect’s reported health benefits. This is not surprising, given that placebo studies are burgeoning, with increasing calls by researchers to ethically harness placebo effects among patients. These calls propose placebos/pla…
Study protocol of an investigation of attention and prediction error as mechanisms of action for latent inhibition of dental fear in humans
Dental phobia negatively affects the dental health and overall health of individuals. This study aims to determine the mechanisms through which pre-exposure retards conditioned dental fear acquisition, recall, and retention. A randomized control trial will be used to identify these mechanisms so that they can be precisely targeted and maximally engaged in preventative efforts
The placebo effect
Mindfulness-Based Analgesia or Placebo Effect? The Development and Evaluation of a Sham Mindfulness Intervention for Acute Experimental Pain
OBJECTIVE: Meta-analyses indicate that mindfulness meditation is efficacious for chronic and acute pain, but most available studies lack active control comparisons. This raises the possibility that placebo-related processes may account, at least in part, for mindfulness effects. The objective of this study was to develop a closely matched sham mindfulness condition to establish whether placebo effects contribute to mindfulness-based interventions…
Pseudoscientific Health Beliefs and the Perceived Frequency of Causal Relationships
Beliefs about cause and effect, including health beliefs, are thought to be related to the frequency of the target outcome (e.g., health recovery) occurring when the putative cause is present and when it is absent (treatment administered vs. no treatment); this is known as contingency learning . However, it is unclear whether unvalidated health beliefs, where there is no evidence of cause-effect contingency, are also influenced by the subjective …
Experimental Assessment of Nocebo Effects and Nocebo Side Effects
Interest in nocebo effects is increasing exponentially: A Google Scholar search for articles referencing nocebo in 1998 (20 years ago) yields 90 results, increasing to 449 in 2008 (10 years ago) and to 1600 in 2018. Increased attention has likely resulted from recognition of the prevalence and potential seriousness of nocebo effects in clinical contexts. It is estimated that up to 97% of reported pharmaceutical side effects are not caused by the …
Knowledge of the aetiology and cost of the nocebo effect is increasing, but conceptualising expectancy and partialling out misattribution remain challenges
The nocebo effect is a concerning phenomenon in which adverse outcomes are triggered by the treatment context. Faasse (2019) summarises recent evidence on mechanisms of the nocebo effect, proposes an updated model, and describes emerging techniques for reducing the nocebo effect. Faasse's model marks an important advance over prior models focussing only on expectancy and classical conditioning by incorporating the role of anxiety, which emerging …
Sources of Placebo-Induced Relief From Nausea
OBJECTIVES: It is well documented that expectancies alter the nauseous response. However, the lack of integration in research examining sources of expectancy has limited our understanding of how expectancies are formed and, consequently, our ability to intervene. The present study explored the role of both instructions and conditioning in placebo-induced relief from nausea. METHODS: The study used a 2 × 2 between-subjects design with instruction …
