Filter by:With this study the investigators want to perform a prospective observational cohort study at Zealand University Hospital, Koege, Denmark. The purpose of this study is twofold: 1. to investigate how expectations predict patients' pain, rehabilitation and quality of life after spinal surgery. 2. to explore the patients' expectations before, and their experiences after, spinal surgery regarding pain, rehabilitation and quality of life.
The purpose of this study is to test if priming expectations of transcranial Direct Current Stimulation (tDCS) can improve the efficacy of tDCS in enhancing motor learning.
Caffeine is a psycho-active substance that is widely consumed in the world. It is seen that its widespread consumption is related to expectancies of consumption as well as cultural factors. Recreationally active individuals may have various expectations from caffeine consumption in line with their lifestyles and goals such as physical, social and/or other aspects. It can be stated that caffeine consumption expectancies have an important role in the process of evaluating consumption patterns. However, in the literature it seems to be very limited information about expectancies related to caffeine consumption. In this direction, the aim of the research was to test the compatibility of Brief-Caffeine Expectancy Questionnaire (B-CaffeQ) to Turkish culture and language. In the study, data will be collected from two separate participant groups and going to analysis. To reveal the structure on the first group (n=250-300 approx.) data, Exploratory Factor Analysis (EFA), and to verify the structure on the second group (n=313) data, Confirmatory Factor Analysis (CFA) will be used. Reliability will be assessed by performing test-retest and internal consistency analyzes on both the two data groups.
The goal of this study is to determine whether a novel questionnaire designed to illicit patient's self-reported expectations across four domains (overall purpose of visit, medication intervention, imaging intervention and disposition) improves patient-provider communication as evaluated by an exit survey during an emergency room visit.
Expectations are a major driver of changes in health-related outcomes and are related to reduced pain after medical treatment. However, no studies have specifically addressed the role of expectations in connection with the success of interventional pain techniques and the specific effect of expectations on diagnostic and therapeutic procedures in this field. Further, there are no studies on prolonged pain reduction after diagnostic nerve blocks. This prospective cohort study will investigate patients' outcome-related expectations measured by validated questionnaires (i.a. the Expectation for Treatment Scale) before standardized diagnostic nerve blocks (i.e. lumbar medial branch and greater occipital nerve blocks) and their association with immediate pain reduction, calculated using a numeric rating scale (NRS) before and after the block. Secondary outcomes are specificity of pain relief duration in relation to the local anesthetic, changes in pain-related interference, quality of life and function, as well as patients' global impression of change after one week in order to assess possible therapeutic effects of the nerve blocks themselves. The sample size of 110 patients is based on a power of 80% and a significance level of 0.05. Additional endpoints will be evaluated using mixed-effects linear regression, non-linear relationships between expectation and endpoints will be modelled using fractional polynomials. This research will quantify the effect of patients' expectations on pain reduction after nerve blocks, extend our knowledge which patients are likely to respond to interventional pain treatments and under which circumstances nerve blocks may exhibit therapeutic effects.
Various studies have shown that a more positive outcome expectation can have an influence on the actual treatment outcome of outpatient psychotherapeutic treatments. Therefore, the aim of this online study is to investigate whether [1] the patients' outcome expectation of outpatient psychotherapy can be optimized by a brief nonguided online intervention and whether [2] this intervention can influence important factors of psychotherapy, such as active cooperation, the therapeutic relationship, motivation, and regular attendance to therapy. To examine these questions, patients who are waiting for outpatient therapy will be randomized into two groups (control vs. intervention group) after baseline assessment. The intervention group will participate in a brief therapy preparation (30 minutes) that focuses on optimizing outcome expectations. Both groups will fill out questionnaires again on the following day, during the diagnostic phase at the beginning of therapy and six months later (or at the end of therapy in case therapy ends before the 6-month-follow-up). Furthermore, therapists will also fill out questionnaires during the diagnostic phase at the beginning of therapy and six months later (or at the end of therapy in case therapy ends before the 6-month-follow-up).
The investigators administer a functional neuroimaging task to investigate the effect of cue expectancy on participants' self-reported ratings across a variety of affective and cognitive domains. The experiment incorporates three tasks in which participants experience and rate 1) somatic pain, 2) vicarious pain, and 3) cognitive effort. In the somatic pain task, participants receive a brief thermal stimulus administered to a site on their arm; in the vicarious pain task, participants watch a short video clip of a patient with back/shoulder pain; in the cognitive effort task, participants perform a cognitively demanding "mental rotation" task that requires them to indicate whether two 3D objects are the same or different when rotated along the y-axis. Each trial follows a sequence that begins with a fixation, followed by a social influence cue, then an expectation rating, followed by a condition-specific stimulus, and then, an actual rating of the outcome experience. There are four events of interest: 1) cue perception, 2) expectation rating, 3) stimulus experience, and 4) outcome rating. First, participants are presented with a cue that depicts how other participants responded to the upcoming stimulus ("cue perception"). Although the participant is told these are real ratings, they are in fact, fabricated data points that vary in intensity (low, high). Then, based on the provided cues, participants are prompted to report their expectation of the upcoming stimulus intensity ("expectation rating") After providing an expectation rating, participants are presented with a condition-specific stimulus (somatic pain, vicarious pain, or cognitive effort) that also varies in three levels of low, medium, high stimulus intensity ("stimulus experience"). Once the stimulus presentation has concluded, participants are prompted to provide an actual rating of their experience ("outcome rating"). For the somatic pain condition, participants rate their expectations and actual experience of how painful the stimulus was; for the vicarious pain condition, they rate their expectations and actual perception of how much pain the patient was in; and for the cognitive condition, the participant provides expectation and actual ratings of task difficulty.
Investigators hypothesize that patients with higher expectations regarding their epidural injection experience a higher pain reduction of their lower back pain and/or leg pain after an epidural injection. Patients' expectations of an epidural injection can influence their level of pain reduction. The primary objective of this study is to investigate the prognostic significance of patient expectations on pain reduction after epidural injections ('expected benefits', see under) in patients with low back pain and/or leg pain. Investigators furthermore hypothesize that patients that have a higher match between their expectations of improvement and actual improvement are more satisfied. A secondary objective of this study is to investigate the prognostic significance of a high match between expectations of improvement and actual improvement on patient satisfaction of the treatment.
It is now known that the level of patients' expectations about a treatment (intervention, medication) can influence their prognosis. Positive expectations impact the effectiveness of the intervention, while negative expectations may lead to adverse events. It would therefore be useful to measure these expectations. However, there is no standardized questionnaire to report the overall level of expectation in the pre-operative phase. A team (led by Pr Meike C Shedden-Mora) has recently developed a questionnaire that aims to assess a patient's general level of expectation regarding a therapeutic intervention, taking into account the direct benefits and the expected adverse effects. This questionnaire, the brief version of the treatment expectation questionnaire (TEX-Q) is composed of 15 items. There's currently no French translation of the TEX-Q, nor has it been tested on a population scheduled for surgery. In addition to expectations regarding the surgical procedure, patients seem to have various expectations regarding the impact and specific role of anesthesia. Little literature exists on specific expectations regarding the role of anesthesia. Thus, we believe it is necessary to validate a French version of the TEX-Q questionnaire (TEX-Q-F) applied to the context of scheduled surgery, as well as to evaluate the specific expectations of anesthesia.
Antidepressant medication is established as an evidence-based, guideline-recommended treatment for Major Depressive Disorders. In the past decades, prescriptions of antidepressant medication have markedly increased, with a specific surge in maintenance prescriptions and therefore, long-term intake, despite guideline recommendations to discontinue antidepressant medication after maintenance therapy has been completed. Over half of fully remitted patients who attempt to discontinue their antidepressant medication report adverse discontinuation symptoms. For many patients, discontinuation symptoms are so severe, that they do not manage to complete their discontinuation attempt. While discontinuation symptoms, deterioration of depressive symptoms, and recurrence can result from pharmacological effects of antidepressant discontinuation, patients' expectations towards discontinuation are likely to play an essential role in occurrence, too. The aim of the present study is to explore the interplay of expectations and pharmacological effects in antidepressant discontinuation. Participants who fulfill German national S3 guideline recommendations will receive a 1:1 chance to either discontinue their antidepressant medication or remain on their antidepressant medication. In addition, participants' expectations are intended to be manipulated by varying verbal instructions using the open-hidden paradigm. Within the open trial arms, participants will receive full information about their treatment (i.e., high expectation). Within the hidden trial arms, participants will be informed about a 50% chance of discontinuing versus remaining on their antidepressant medication (i.e., moderate expectation). Participants will have a 1:1:1:1 chance of being allocated to 1 of the 4 experimental groups: open discontinuation (OD), hidden discontinuation (HD), open continuation (OC), or hidden continuation (HC) of their antidepressant medication. This preregistration is part of the collaborative research center (CRC) SFB/TRR289 which aims to characterize the psychological and neurobiological effects of treatment expectations on health outcome (https://treatment-expectation.de) and is funded by the Deutsche Forschungsgemeinschaft (DFG).
