RESUMO

PURPOSE: Limited research has examined recovery processes and conceptualisations of recovery within orthorexia nervosa (ON). This study harnessed Instagram data to examine how people who self-identify with ON use the hashtag #OrthorexiaRecovery and how recovery is represented within this online space. METHODS: 500 textual posts containing #OrthorexiaRecovery were extracted from Instagram. Co-occurring hashtags were analysed descriptively to determine whether this online space is specific to ON, and textual data were analysed using reflexive thematic analysis. RESULTS: The hashtag analysis indicated that #OrthorexiaRecovery is being used within a wider context of eating disorder recovery and awareness, but also provides deep insights into experiences of recovery from ON. The thematic analysis generated five themes: the invisibility of orthorexia; a turbulent and continuous process; finding food freedom; from compulsive exercise to intuitive movement; a community of support. Our findings suggest that people with self-reported ON experience recovery as a continuous process and the current invisibility of ON within diagnostic criteria and wider society impedes recovery. While working towards recovery, users aimed to be free from diet culture, become more attuned to their bodies, and develop more adaptive relationships with food and fitness. Users noted a general lack of support for people with ON and so used this online space to create a supportive community, though some content was potentially triggering. CONCLUSION: Our findings highlight the importance of increased recognition of ON and the potential value of targeting societal norms and harnessing social identity resources within therapeutic interventions for ON.

RESUMO

PURPOSE: Limited research has explored conceptualisations of health and healthy eating in orthorexia nervosa (ON). This mixed-methods study aimed to investigate how 'health' and 'healthy eating' are conceptualised by individuals at risk for ON. This study examined the potential relationships between health anxiety, beliefs about health controllability and orthorexic symptomatology in our broader sample. METHODS: A total of 362 participants took a survey on health anxiety (measured with the HAQ), beliefs about the controllability of one's own health (IMHLC) and ON symptomatology (E-DOS and EHQ). Participants 'at risk' for ON (n = 141), also completed an online qualitative survey about conceptualisations of health and healthy eating. Qualitative data were analysed using thematic analysis (part A). The PROCESS macro for SPSS was used for the quantitative analysis (part B). RESULTS: Conceptualisations of health and healthy eating were complex. Four themes were generated from our qualitative data: 'health is more than thin ideals', 'healthy food equals healthy mind', 'a body that works for you' and 'taking control of your body'. Our quantitative analysis revealed that health anxiety and beliefs in health controllability independently predicted ON symptomatology. CONCLUSION: A richer understanding of what health means in the context of ON is important, given the centrality of this concept to the proposed classification of this disordered eating style. Our findings highlight that both health anxiety and health controllability are important targets for future investigation, given their potential relevance to the aetiology and treatment of ON. LEVEL OF EVIDENCE: Level V, based on a descriptive study.

RESUMO

PURPOSE: Orthorexia nervosa (ON) is a proposed new eating disorder, used to describe a pathological obsession with healthy or 'clean' eating. Although some quantitative research has been carried out in ON, very little qualitative work has been published to date to explore individual experiences of ON. Thus, this study aimed to explore individuals' personal experiences of ON, as described in online blogs. METHODS: Fifteen women bloggers, who self-identified as having ON, consented for their blog entries to be analysed in this study. Forty pre-existing blog entries describing the first-person experiences of ON were analysed using thematic analysis. RESULTS: Three key themes were discussed: (1) initial motivations for a healthier lifestyle, (2) fuelling the problem-social influences, and: (3) when healthy becomes unhealthy. Bloggers described the role of social messages, comparison with others around ideas of 'healthiness', as well as confusion around diagnosis as factors influencing their disordered eating. They also described the exacerbating impact of perfectionism and perceived control, as well as a confirmatory cycle of fear and avoidance. For some bloggers, increased physical symptoms in response to feared foods provided confirmation for these fears, further exacerbating food avoidance. CONCLUSION: Whilst the debate around the diagnosis of ON continues, these bloggers' accounts suggest that ON is experienced as a legitimate, debilitating disorder, worthy of clinical and research investigation. This study provides evidence of some of the potential triggers and maintaining factors for this disordered eating style. LEVEL OF EVIDENCE: Level V, qualitative descriptive study.

RESUMO

BACKGROUND: Placebo effects and their underpinning mechanisms are increasingly well understood. However, this is poorly communicated to participants in placebo-controlled trials. For valid informed consent, participants should be informed about the potential benefits and risks of participating in placebo-controlled trials. Existing information leaflets often fail to describe the potential benefits and adverse effects associated with placebo allocation. This study tested the effects of a new website designed to inform patients about placebo effects (The Power of Placebos, PoP). PoP was designed using qualitative methods in combination with theory- and evidence-based approaches to ensure it was engaging, informative, and addressed patients' concerns. OBJECTIVE: This study aimed to test the effects of PoP, compared with a control website, on people's knowledge about placebo and the ability to make an informed choice about taking part in a placebo-controlled trial. METHODS: A total of 350 adults with back pain recruited from 26 general practices in Southern England participated in this Web-based study. Participants were randomly assigned to PoP (which presented scientifically accurate information about placebo effects in an engaging way) or a control website (based on existing information leaflets from UK trials). Participants self-completed Web-based pre- and postintervention questionnaire measures of knowledge about placebo effects and preintervention questionnaire measures of attitudes toward and intentions to participate in a placebo-controlled trial. The 2 primary outcomes were (1) knowledge and (2) informed choice to take part in a placebo-controlled trial (computed from knowledge, attitudes, and intentions). RESULTS: After viewing PoP, participants had significantly greater knowledge about placebos (mean 8.28 [SD 1.76]; n=158) than participants who viewed the control (mean 5.60 [SD 2.24]; n=174; F1,329=173.821; P<.001; η2=.346). Participants who viewed PoP were 3.16 times more likely than those who viewed the control to make an informed choice about placebos (χ21=36.5; P<.001). CONCLUSIONS: In a sample of adults with back pain, PoP increased knowledge and rates of informed choice about placebos compared with a control website. PoP could be used to improve knowledge about placebo effects in back pain. After essential further development and testing in clinical trial settings, it could support informed consent in placebo-controlled trials.

RESUMO

INTRODUCTION: Patients require an accurate knowledge about placebos and their possible effects to ensure consent for placebo-controlled clinical trials is adequately informed. However, few previous studies have explored patients' baseline (ie, pretrial recruitment) levels of understanding and knowledge about placebos. The present online survey aimed to assess knowledge about placebos among patients with a history of back pain. DESIGN: A 15-item questionnaire was constructed to measure knowledge about placebos. Additional questions assessed sociodemographic characteristics, duration and severity of back pain, and previous experience of receiving placebos. SETTING: Participants recruited from community settings completed the study online. RESULTS: 210 participants completed the questionnaire. 86.7% had back pain in the past 6 months, 44.3% currently had back pain. 4.3% had received a placebo intervention as part of a clinical trial and 68.1% had previously read or heard information about placebos. Overall knowledge of placebos was high, with participants on average answering 12.07 of 15 questions about placebos correctly (SD=2.35). However, few participants correctly answered questions about the nocebo effect (31.9% correct) and the impact of the colour of a placebo pill (55.2% correct). CONCLUSIONS: The findings identified key gaps in knowledge about placebos. The lack of understanding of the nocebo effect in particular has implications for the informed consent of trial participants. Research ethics committees and investigators should prioritise amending informed consent procedures to incorporate the fact that participants in the placebo arm might experience adverse side effects.

RESUMO

BACKGROUND: Orthorexia Nervosa (ON) is a disordered eating style involving an unhealthy obsession with 'healthy' or 'clean' eating. Its aetiology is still poorly understood and is not yet recognised in diagnostic manuals. While ON has been associated with Obsessive Compulsive (OC) symptoms and perfectionism, no study to date has looked at the relationship between OC symptoms and ON tendencies via perfectionism, or the influence of two facets of perfectionism in this relationship, namely evaluative concern and achievement striving. Examining the potential role of perfectionism helps to understand the aetiology of ON as well as inform potential treatments tailored specifically for ON and comorbid OC symptoms. METHODS: In this cross sectional study, we tested 507 participants (n = 70 males, n = 69 at risk of ON) on questionnaires measuring OC symptoms, perfectionism and ON symptoms. We ran two mediation analyses to look at the overall relationship between perfectionism and OC and ON symptoms (Model 1) as well as the specific contribution of evaluative concern and achievement striving in the relationship between OC and ON symptoms (Model 2). RESULTS: We found that perfectionism partially mediated the relationship between OC and ON symptoms. Specifically, we found that while achievement striving and evaluative concern were associated with OC symptoms, only achievement striving was significantly associated with ON symptoms, mediating the relationship between OC and ON symptoms. CONCLUSIONS: This study highlighted the role of one key facet of perfectionism (achievement striving) in the aetiology of ON. The role of achievement striving was indicated as a transdiagnostic construct explaining the link between ON and OC symptoms. These findings are discussed in terms of their implications for treatment models, specifically in terms of the potential role of targeting perfectionism in ON treatment.


Orthorexia Nervosa (ON) is a disordered eating style involving an obsession with extreme 'healthy' eating, causing the person distress and impairment. People with ON are more likely to have symptoms of Obsessive Compulsive Disorder (OCD), such as obsessive thoughts that are reduced by repetitive behaviours. There is also evidence that perfectionism (e.g. having very high personal standards) plays an important role in both ON and OCD.Our study of 507 participants looked at whether two aspects of perfectionism: (1) concern about being evaluated negatively by others; 'evaluative concern', and: 2) striving for very high standards; 'achievement striving' were linked to higher levels of orthorexic and obsessive-compulsive symptoms. Our research also looked at whether these aspects of perfectionism explained the link between orthorexic and obsessive-compulsive symptoms.We found that both aspects of perfectionism were linked to obsessive-compulsive symptoms. However, achievement striving specifically helped to explain the link between orthorexic and obsessive-compulsive symptoms. These findings suggest that treatment focusing on achievement striving might be particularly useful for people with ON, and for those who have both orthorexic and obsessive-compulsive symptoms.

RESUMO

BACKGROUND: Existing research highlights the link between certain personality traits and mental health in surgeons. However, little research has explored the important role of psychological skills and qualities in potentially explaining this link. A cross-sectional survey of UK-based surgeons was used to examine whether two such skills (psychological flexibility and resilience) helped to explain why certain personality traits might be linked to mental health in surgeons. METHOD: An online survey comprising measures of personality (neuroticism, extraversion and conscientiousness), psychological skills/qualities (psychological flexibility and resilience) and mental health (depression, anxiety, stress and burnout) was sent to surgeons practising in the UK. Mediation analyses were used to examine the potential mediating role of psychological flexibility and resilience in explaining the relationship between personality factors and mental health. RESULTS: A total of 348 surgeons completed the survey. In all 12 mediation models, psychological flexibility and/or resilience played a significant role in explaining the relationship between personality traits (neuroticism, extraversion and conscientiousness) and mental health (depression, anxiety and burnout). CONCLUSION: Findings suggest that it is not only a surgeon's personality that is associated with their mental health, but the extent to which a surgeon demonstrates specific psychological qualities and skills (psychological flexibility and resilience). This has important implications for improving surgeons' mental wellbeing, because psychological flexibility and resilience are malleable, and can be successfully targeted with interventions in a way that personality traits cannot.

RESUMO

OBJECTIVES: To test whether a newly developed person-, theory- and evidence-based website about acupuncture helps patients make informed decisions about whether or not to use acupuncture for back pain. METHODS: A randomised online study compared a newly developed 'enhanced website' to a 'standard website'. The enhanced website provided evidence-based information in a person-based manner and targeted psychological constructs. The standard website was based on a widely used patient information leaflet. In total, 350 adults with recent self-reported back pain were recruited from general practices in South West England. The two primary outcomes were knowledge change and making an informed choice about using acupuncture. Secondary outcomes were beliefs about and willingness to have acupuncture. RESULTS: Participants who viewed the enhanced acupuncture website had a significantly greater increase in knowledge about acupuncture (M = 1.1, standard deviation (SD) = 1.7) than participants who viewed the standard website (M = 0.2, SD = 1.1; F(1, 315) = 37.93, p < 0.001, η2 = .107). Participants who viewed the enhanced acupuncture website were also 3.3 times more likely to make an informed choice about using acupuncture than those who viewed the standard website (χ2(1) = 23.46, p < 0.001). There were no significant effects on treatment beliefs or willingness to have acupuncture. CONCLUSION: The enhanced website improved patients' knowledge and ability to make an informed choice about acupuncture, but did not optimise treatment beliefs or change willingness to have acupuncture. The enhanced website could be used to support informed decision-making among primary care patients and members of the general public considering using acupuncture for back pain.

RESUMO

OBJECTIVES: Despite the prevalence of acupuncture treatment in the UK, and the increasing evidence of safety and effectiveness, the information presented to patients by practitioners frequently contains inaccuracies. As knowledge of treatment affects both patient decision-making and treatment outcomes, this study aimed to establish what is known about acupuncture in a sample of people who had, and had not, previously experienced acupuncture. DESIGN: A 15-item questionnaire was constructed to assess knowledge of acupuncture. SETTING: Online survey of people with a history of back pain. RESULTS: 202 participants completed the questionnaire. 66.8% of the sample was female and 33.2% male, with a mean age of 35 years (range 18-74 years). 87.6% had back pain in the past six months, 44.1% currently. 21.8% had previously received acupuncture, and 69.8% had previously read or heard information about acupuncture. On average participants answered 11.03 of 15 questions about acupuncture correctly (SD=2.64). Items relating to common concerns about acupuncture, acupuncture efficacy, and types of acupuncture were correctly answered by ≥80% of participants. Participants possessed less knowledge of accessibility, Government legislation, and methods of administration. CONCLUSIONS: The study identified key gaps in knowledge about acupuncture among patients. In particular, many participants were unaware that acupuncture is available from the UK National Health Service and that acupuncturists are not subject to statutory regulation in the UK. These knowledge gaps should be addressed in order to increase people's understanding of and access to acupuncture.

RESUMO

BACKGROUND: According to established ethical principles and guidelines, patients in clinical trials should be fully informed about the interventions they might receive. However, information about placebo-controlled clinical trials typically focuses on the new intervention being tested and provides limited and at times misleading information about placebos. OBJECTIVE: We aimed to create an informative, scientifically accurate, and engaging website that could be used to improve understanding of placebo effects among patients who might be considering taking part in a placebo-controlled clinical trial. METHODS: Our approach drew on evidence-, theory-, and person-based intervention development. We used existing evidence and theory about placebo effects to develop content that was scientifically accurate. We used existing evidence and theory of health behavior to ensure our content would be communicated persuasively, to an audience who might currently be ignorant or misinformed about placebo effects. A qualitative 'think aloud' study was conducted in which 10 participants viewed prototypes of the website and spoke their thoughts out loud in the presence of a researcher. RESULTS: The website provides information about 10 key topics and uses text, evidence summaries, quizzes, audio clips of patients' stories, and a short film to convey key messages. Comments from participants in the think aloud study highlighted occasional misunderstandings and off-putting/confusing features. These were addressed by modifying elements of content, style, and navigation to improve participants' experiences of using the website. CONCLUSIONS: We have developed an evidence-based website that incorporates theory-based techniques to inform members of the public about placebos and placebo effects. Qualitative research ensured our website was engaging and convincing for our target audience who might not perceive a need to learn about placebo effects. Before using the website in clinical trials, it is necessary to test its effects on key outcomes including patients' knowledge and capacity for making informed choices about placebos.

RESUMO

INTRODUCTION: Potential acupuncture patients seek out information about acupuncture from various sources including websites, many of which are unreliable. We aimed to create an informative, scientifically accurate and engaging website to educate patients about acupuncture for back pain and modify their beliefs in a way that might enhance its clinical effects. METHODS: We used psychological theory and techniques to design an evidence-based website, incorporating multimedia elements. We conducted qualitative "think aloud" audio-recorded interviews to elicit user views of the website. A convenience sample of ten participants (4 male; aged 21-64 years from the local community) looked at the website in the presence of a researcher and spoke their thoughts out loud. Comments were categorised by topic. RESULTS: The website comprises 11 main pages and addresses key topics of interest to potential acupuncture patients, including beneficial and adverse effects, mechanisms of action, safety, practicalities, and patients' experiences of acupuncture. It provides information through text, evidence summaries and audio-clips of four patients' stories and two acupuncturists' descriptions of their practice, and three short films. Evidence from the think aloud study was used to identify opportunities to make the website more informative, engaging, and user-friendly. CONCLUSIONS: Using a combination of psychological theory and qualitative interviews enabled us to produce a user-friendly, evidence-based website that is likely to change patients' beliefs about acupuncture for back pain. Before using the website in clinical settings it is necessary to test its effects on key outcomes including patients' beliefs and capacity for making informed choices about acupuncture.

RESUMO

INTRODUCTION: Components other than the active ingredients of treatment can have substantial effects on pain and disability. Such 'non-specific' components include: the therapeutic relationship, the healthcare environment, incidental treatment characteristics, patients' beliefs and practitioners' beliefs. This study aims to: identify the most powerful non-specific treatment components for low back pain (LBP), compare their effects on patient outcomes across orthodox (physiotherapy) and complementary (osteopathy, acupuncture) therapies, test which theoretically derived mechanistic pathways explain the effects of non-specific components and identify similarities and differences between the therapies on patient-practitioner interactions. METHODS AND ANALYSIS: This research comprises a prospective questionnaire-based cohort study with a nested mixed-methods study. A minimum of 144 practitioners will be recruited from public and private sector settings (48 physiotherapists, 48 osteopaths and 48 acupuncturists). Practitioners are asked to recruit 10-30 patients each, by handing out invitation packs to adult patients presenting with a new episode of LBP. The planned multilevel analysis requires a final sample size of 690 patients to detect correlations between predictors, hypothesised mediators and the primary outcome (self-reported back-related disability on the Roland-Morris Disability Questionnaire). Practitioners and patients complete questionnaires measuring non-specific treatment components, mediators and outcomes at: baseline (time 1: after the first consultation for a new episode of LBP), during treatment (time 2: 2 weeks post-baseline) and short-term outcome (time 3: 3 months post-baseline). A randomly selected subsample of participants in the questionnaire study will be invited to take part in a nested mixed-methods study of patient-practitioner interactions. In the nested study, 63 consultations (21/therapy) will be audio-recorded and analysed quantitatively and qualitatively, to identify communication practices associated with patient outcomes. ETHICS AND DISSEMINATION: The protocol is approved by the host institution's ethics committee and the NHS Health Research Authority Research Ethics Committee. Results will be disseminated via peer-reviewed journal articles, conferences and a stakeholder workshop.

RESUMO

Although there has been a lot of research looking at the placebo response, nocebo responses in the healthcare setting have been largely overlooked. This article explores the potential role of negative patient-doctor communication in facilitating nocebo responses in the medical consultation. We suggest that invalidation, that is, communicating a lack of understanding and acceptance to the patient (albeit unintentionally), is a key factor in understanding the nocebo response. This article reviews evidence from the experimental and healthcare setting, which suggests that the negative effects of invalidation may be stronger than we think.
