Psychiatrists' Attitudes Toward Non-Pharmacologic Factors Within the Context of Antidepressant Pharmacotherapy

Placebos in pediatrics: A cross-sectional survey investigating physicians' perspectives

OBJECTIVE

Placebo responses are significantly higher in children than in adults, suggesting a potential underused treatment option in pediatric care. To facilitate the clinical translation of these beneficial effects, we explored physicians' current practice, opinions, knowledge, and likelihood of recommending placebos in the future.

METHODS

A cross-sectional web-based survey administered by REDCap was conducted at Boston Children's Hospital between October 2021 and March 2022. Physicians (n = 1157) were invited to participate through an email containing a link to a 23-item survey designed to assess physicians' attitudes and perceptions towards the clinical use of placebo in pediatrics.

RESULTS

From 207 (18%) returned surveys, 109 (9%) were fully completed. Most respondents (79%) believed that enhancing the therapeutic components that contribute to the placebo response may be a way of improving pediatric care. However, whereas most (62%) found placebo treatments permissible, only one-third reported recommending them. In pediatrics, placebos are typically introduced as a medicine that "might help" (43%). The most common treatments recommended to enhance placebo effects are physical therapy, vitamins, and over-the-counter analgesics. Physicians most frequently recommend placebos for occasional pain, headaches, and anxiety disorders. Finally, the great majority of physicians (87%) stated they would be more likely to recommend placebo treatments if there were safety and ethical guidelines for open-label placebos.

CONCLUSIONS

Placebo treatments seem permissible to physicians in pediatric care, but the development of safety and ethical guidelines may be necessary before physicians systematically incorporate the benefits of the placebo effect in pediatrics.

Resilient Prescribing: An Approach to Psychotropic Use in Deployed Environments

Resilient prescribing is an approach to the use of psychotropics that considers the significance of the treatment beyond the direct effects of the medication. Within this strengths-based approach, those who are prescribed medications must retain a sense of self-efficacy, understand the importance of their own actions in their recovery, have reasonable expectations of what a medication can and cannot do, and avoid the adoption of a disempowering illness identity. These constitute the principles of resilient prescribing. In this manuscript, we explore these principles with consideration for how they may be applied in deployed settings where the ability of service members to recover from behavioral health concerns is mission critical. These principles offer a roadmap to prescribing that builds upon the service members' own strengths and has the potential to amplify the positive impacts of mental health treatment.

The Importance of Patient Expectations: A Mixed-Methods Study of U.S. Psychiatrists

Objective: To examine how psychiatrists think about and modulate non-specific factors (e.g., hope, expectations) in clinical practice. Methods: U.S. psychiatrists were recruited for two studies assessing attitudes and behaviors related to non-specific factors. Study 1 entailed remote qualitative focus groups (k = 7) with n = 26 participants (36.0% female). Study 2 was a quantitative survey with n = 346 respondents (34.0% female) designed to assess the generalizability of focus group findings. Results: Four themes were identified in Study 1 that were used to inform the survey (Study 2): (1) Expectations (2) Hope, (3) Placebo Effect, and (4) Aesthetic Features. Nearly all surveyed psychiatrists (92.2%) considered patient expectations at least "most of the time" when interacting with a patient. Focus groups revealed that psychiatrists often attempt to balance optimism and realism to improve outcomes. A majority of survey respondents believed office design and physician attire could at least somewhat influence expectations (72.5 and 77.3%, respectively) and even outcomes (51.5 and 58.7%, respectively). Focus group psychiatrists described how physical features may be used as therapeutic tools. Conclusions: Psychiatrists are highly mindful of patient expectations. Although there is variability in the perceived importance of expectations, hope, the placebo effect, and aesthetic features, many utilize these factors in clinical practice.

Physical therapists' perspectives on using contextual factors in clinical practice: Findings from an Italian national survey

Background

Contextual factors (CFs) represent a potential therapeutic tool to boost physiotherapy outcomes, triggering placebo effects. Nevertheless, no evidence about the use of CFs among physical therapists is currently available.

Objective

To investigate the use of CFs and the opinion of Italian physical therapists specialized in Orthopaedic Manual Therapy (OMTs) on their therapeutic benefits.

Design

An exploratory cross-sectional online survey.

Methods

A 17-item questionnaire and 2 clinical vignettes assessed the perspective of OMTs on the adoption of CFs in daily clinical practice. The target population was composed of 906 OMTs. An online survey was performed in 2016 using SurveyMonkey Software. Data were analyzed by descriptive and inferential statistics.

Results

A total of 558 volunteers (61.6% of the target OMT population) participated in the study. Half of the participants (52.0%) claimed to use CFs frequently in their practice. More of 50% of OMTs valued the therapeutic significance of CFs for different health problems as determined by a combined psychological and physiological effect. OMTs considered the use of CFs ethically acceptable when they exert beneficial therapeutic effects and their effectiveness has emerged in previous clinical experiences (30.6%). They disagreed on the adoption of CFs when they are deceptive (14.1%). Moreover, OMTs did not communicate the adoption of CFs to patients (38.2%), and CFs were usually used in addition to other interventions to optimize clinical responses (19.9%). Psychological mechanisms, patient’s expectation and conditioning were believed to be the main components behind CFs (7.9%).

Limitations

Considering that the data collected were self-reported and retrospective, recall and response biases may limit the internal and external validity of the findings.

Conclusions

OMTs used CFs in their clinical practice and believed in their therapeutic effect. The knowledge of CFs, placebo and nocebo mechanisms and their clinical effects should be included in physical therapists’ university studies.

Attitudes toward placebo-controlled clinical trials among depressed patients in Japan

BACKGROUND

Placebo-controlled clinical trials are the standard in the design of clinical studies for the licensing of new drugs. Medical and ethical concerns regarding placebo use still exist in clinical trials of depressed patients. The aim of this study was to investigate the attitudes toward placebo-controlled clinical trials and to assess factors related to the willingness to participate in such trials among depressed patients in Japan.

METHODS

A total of 206 depressed patients aged 49.5 ± 15.7 years (mean ± SD) who were admitted to three psychiatric hospitals were recruited for a cross-sectional study from June 2015 to March 2016. After a thorough explanation of the placebo, the study participants completed a brief 14-item questionnaire developed to evaluate patients' attitudes regarding possible participation in placebo-controlled clinical trials. The Quick Inventory of Depressive Symptomatology was also administered to assess depressive symptoms.

RESULTS

The results indicated that 47% of the patients would be willing to participate in a placebo-controlled clinical trial. Expectations for the improvement of disease, desire to receive more medical care, encouragement by family or friends, and desire to support the development of new drugs were associated with the willingness to participate in such trials, whereas a belief that additional time would be required for medical examinations and fear of exacerbation of symptoms due to placebo use were associated with non-participation.

LIMITATIONS

Patients were asked about possible participation in placebo-controlled clinical trials.

CONCLUSIONS

Less than half of the respondents were willing to participate in placebo-controlled clinical trials. Attitudes toward participation in a placebo-controlled clinical trial need to be considered when deciding whether to conduct such a trial.

Physicians' beliefs about placebo and nocebo effects in antidepressants - an online survey among German practitioners

BACKGROUND

While substantial placebo and nocebo effects have been documented in antidepressant clinical trials, physicians' awareness of the nonspecific effects in routine antidepressant treatment remains unclear. The study investigated physicians' beliefs and explanatory models regarding the desired effects and undesired side effects of antidepressants, with specific emphasis on nonspecific effects accounted for by placebo and nocebo mechanisms.

METHODS

An online survey was conducted among 87 physicians (40.2% psychiatrists, 25.3% neurologists, 24.1% general practitioners, 12.6% internists, 21.8% other). The survey assessed the physician's beliefs in antidepressant effectiveness, as well as 6 explanatory models regarding antidepressant effectiveness and 8 explanatory models for the occurrence of side effects.

RESULTS

Most physicians (89.7%) believed in the effectiveness of antidepressants while acknowledging a considerable role of the placebo effect by attributing around 40% of the total effects to nonspecific factors. For both antidepressant effectiveness and the occurrence of side effects, pharmacological effects were rated as most important (93.1% and 80.5% agreement), but physicians also attributed a substantial role to the patients' expectations (63.2% and 58.6%) and experiences (60.9% and 56.3%). Concerning the physician's own role in promoting nonspecific effects in antidepressant effectiveness, highest endorsements were found for the quality of the physician-patient-relationship (58.6%) and own expectations (41.4%). When asked about side effects, fewer participants agreed that informing the patient about known side effects (25.2%) or the physicians' expectations themselves (17.2%) could induce side effects.

CONCLUSION

Physicians, when prescribing antidepressants, are generally open towards nonspecific treatment mechanisms. However, they consider their own influence as less important than the patient's side, especially when it comes to the explanation of unwanted side effects. Awareness of the possible beneficial as well as malicious role of nonspecific mechanisms should be fostered as the first step towards optimizing antidepressant treatment by promoting placebo while avoiding nocebo effects.
