RESUMEN

OBJECTIVE: This feasibility study aimed to assess the acceptability of using smartphone notifications to modify the medication beliefs of people with gout. We evaluated the feasibility and acceptability of a smartphone application using the Technology Acceptance Model. We explored adherence rate differences and outcomes between the intervention and control groups. METHODS: Fifty-two patients with gout who were prescribed allopurinol were randomly assigned to either active control (n = 24) or intervention group (n = 28). Over 3 months, both groups used the study app on their smartphones. The active control group received notifications about general health advice, whereas the intervention group received adherence-targeted notifications. The feasibility and acceptability of the smartphone app was measured through semistructured interviews. Adherence rate was assessed through serum urate levels and missed doses at 3 timepoints: baseline, 3 months (post intervention), and 6 months (follow-up). RESULTS: The smartphone app demonstrated high feasibility, with strong participant retention and compliance. The participants expressed high levels of satisfaction with the app's user-friendliness and content, highlighting its acceptability. Both groups showed a significant reduction in missed doses over time (P < 0.05), but no significant differences in serum urate levels were found between the groups. Patients who received adherence-targeted notifications reported finding it more convenient to take allopurinol and expressed higher overall treatment satisfaction throughout the study. CONCLUSION: Adherence-targeted notifications have the potential to be an effective and scalable approach to supporting medication adherence in patients with gout. Further research is needed with larger samples to refine the components of the intervention and explore its optimal implementation.

RESUMEN

OBJECTIVE: To investigate the effect of colchicine prophylaxis on gout remission when commencing urate lowering therapy (ULT), and illness perceptions of people in remission, using two definitions of gout remission. METHODS: Data from a 12-month double-blind placebo-controlled trial of 200 people with gout commencing allopurinol were analyzed. Participants were randomly assigned to prophylaxis with 0.5mg daily colchicine or placebo for six months, followed by six months of additional follow-up. Gout remission was assessed using the 2016 preliminary definition or simplified definition without patient reported outcomes. Illness perceptions were assessed using a gout-specific brief illness perception questionnaire (BIPQ). RESULTS: In the first six months, few participants were in remission according to either the 2016 preliminary definition (3% for colchicine and 4% for placebo) or the simplified definition (7% for colchicine and 12% for placebo). In the second six months, after study drug (colchicine or placebo) discontinuation, fewer participants in the colchicine group than in the placebo group were in remission according to the 2016 preliminary definition (4% vs. 14%, p=0.03), and the simplified definition (14% vs 28%, p=0.02). Participants fulfilling remission using either definition had more favorable perceptions about their gout symptoms and illness concerns, as well as consequences, when using the simplified definition. CONCLUSION: Using either definition, six months of colchicine prophylaxis when initiating ULT does not provide an advantage in the fulfilment of gout remission. People fulfilling either definition report fewer symptoms, lower concern about their gout, and when using the simplified definition, are less affected by gout.

RESUMEN

OBJECTIVES: This study aimed to assess the psychometric properties of two widely used fatigue scales in a sample of patients with inflammatory conditions. METHODS: Rasch analysis was used to examine scale reliability, item bias, unidimensionality and overall fit to the Rasch model. Sub-test methodology was utilised to attempt to improve model fit for the CFQ and BRAF-MDQ. RESULTS: Initial analysis displayed strong reliability (PSI=0.89 0.96), alongside a lack of item bias in both scales. However, evidence for unidimensionality was not found for either scale. Overall fit to the Rasch model was marginal for the CFQ, and misfitting for the BRAF-MDQ. Local dependency was observed, as well as significant item misfit for both scales. Sub-test modifications resulted in the best model fit for the BRAF-MDQ (χ2(16)=15.77, p=0.469) and the CFQ (χ2(25)=15.49, p=0.929). Modifications resulted in improved fit, reductions in measurement error, and the production of ordinal-to-interval conversion tables for both scales. Conversion tables apply the benefits of enhanced measurement accuracy, valid comparison of BRAF-MDQ and CFQ scores to other interval-level data, appropriate use in parametric statistics, and enhanced precision in clinical cut-off scores-without the need to change administration format. CONCLUSION: The BRAF-MDQ and CFQ are valid, reliable tools for fatigue assessment. Psychometric indices and content factors suggest the CFQ is suited to measuring general fatigue, particularly when response burden is a concern, while the BRAF-MDQ should be used in clinical presentations where other symptoms are severe and the impact of fatigue on daily living, emotional, and social well-being is of interest.

RESUMEN

BACKGROUND: Side-effect concerns are a major barrier to vaccination against COVID-19 and other diseases. Identifying cost- and time-efficient interventions to improve vaccine experience and reduce vaccine hesitancy-without withholding information about side effects-is critical. PURPOSE: Determine whether a brief symptom as positive signals mindset intervention can improve vaccine experience and reduce vaccine hesitancy after the COVID-19 vaccination. METHODS: English-speaking adults (18+) were recruited during the 15-min wait period after receiving their second dose of the Pfizer COVID-19 vaccination and were randomly allocated to the symptom as positive signals mindset condition or the treatment as usual control. Participants in the mindset intervention viewed a 3:43-min video explaining how the body responds to vaccinations and how common side effects such as fatigue, sore arm, and fever are signs that the vaccination is helping the body boost immunity. The control group received standard vaccination center information. RESULTS: Mindset participants (N = 260) versus controls (N = 268) reported significantly less worry about symptoms at day 3 [t(506)=2.60, p=.01, d=0.23], fewer symptoms immediately following the vaccine [t(484)=2.75, p=.006, d=0.24], and increased intentions to vaccinate against viruses like COVID-19 in the future [t(514)=-2.57, p=.01, d=0.22]. No significant differences for side-effect frequency at day 3, coping, or impact. CONCLUSIONS: This study supports the use of a brief video aimed at reframing symptoms as positive signals to reduce worry and increase future vaccine intentions.

Side-effect concerns are a major barrier to vaccination against COVID-19 and other diseases. Therefore, the purpose of this study was to determine whether a brief symptom as positive signals mindset intervention could improve vaccine experience and reduce vaccine hesitancy after the COVID-19 vaccination. Participants were recruited during the 15-min wait period after receiving their second dose of the Pfizer COVID-19 vaccination and were randomly allocated to a treatment as usual control condition or to a mindset intervention condition which entailed watching a 3:43-min video explaining how the body responds to vaccinations and how common side effects such as fatigue, sore arm, and fever are signs that the vaccination is helping the body boost immunity. Compared with participants in the control condition, participants in the mindset intervention condition reported significantly less worry about symptoms at day 3, fewer symptoms immediately following the vaccine and increased intentions to vaccinate against viruses like COVID-19 in the future. No significant differences emerged for side-effect frequency at day 3, coping, or impact. These finding provide initial support for cost- and time-efficient interventions to improve vaccine experience and reduce vaccine hesitancy without withholding information about side effects.

RESUMEN

BACKGROUND: Involving patients in treatment decisions is commonplace in healthcare, and patients are frequently accompanied by a companion (support person). Companions are often actively involved in medical consultations, yet their impact on decisions to change medications is unknown. PURPOSE: This study examines the influence of companions on a patient's decision to transition from their bio-originator therapy to a biosimilar. METHODS: A parallel, two-arm randomized controlled trial was conducted with 79 patients taking a bio-originator for rheumatic diseases who regularly attend clinic with a companion. Patients were randomized to receive an explanation about a hypothetical transition to a biosimilar alone or with their companion. Patients reported willingness to transition, risk perceptions, difficulty understanding, social support, and completed the Decisional Conflict Scale and Satisfaction with Decision Scale. RESULTS: Companions did not influence decisions to transition to biosimilars or cognitive and affective risk perceptions. Accompanied patients reported more difficulty understanding the explanation (p = .006, Cohen's d = .64) but thought it was more important to receive information with companions (p = .023, Cohen's d = -.52). Companions did not impact decision satisfaction or decisional conflict. Receiving emotional, but not practical support, was associated with less decisional conflict in accompanied patients (p = .038, r2 = 0.20). CONCLUSIONS: The presence of companions does not seem to influence risk perceptions or decisions about transitioning to biosimilars. Companions, however, impact the patient's reporting of their ability to understand treatment explanations. Providers should check understanding in all patients but may need to provide additional time or educational resources to accompanied patients and companions.

RESUMEN

Patient perceptions influence biosimilar uptake in non-mandatory transitions. Companions (support people) are often actively involved in the patient's medical journey and are likely to have unique perceptions of biosimilars, which may shape patient attitudes. This study explores the congruence between patient and companion perceptions towards biosimilars and their information needs. Patients taking bio-originators for rheumatic diseases (59% for rheumatoid arthritis) and their companions received an explanation about biosimilars. Participants (N = 78) completed questionnaires assessing their familiarity with biosimilars, perceptions, concerns, and benefits of being accompanied. Contingency tables and paired sample t-tests were used to explore differences in familiarity, confidence in knowledge, and perceptions. Intra-class correlation coefficients were calculated to assess the degree of congruence for perceptions towards biosimilars. Companions were significantly less familiar with biosimilars (p = 0.014, Cramer's V = 0.28) and reported lower confidence in their knowledge (p = 0.006, Cohen's d = 0.47) than patients. Companions and patients had moderate to good congruency for perceptions toward confidence in biosimilar use and safety, efficacy, and side-effect expectations (intra-class correlation coefficients ranging from 0.75 to 0.81). Companions and patients were most concerned about safety and effectiveness. Companions also reported concerns about cost savings driving the transition, while patients had concerns about uncertainty and testing. Patients reported the ability for discussion, improved understanding, and validation as benefits of being accompanied. Companions and patients have similar levels of perceptions and expectations towards biosimilars but report some unique information needs. Future educational interventions should involve companions and address their concerns to help improve biosimilar acceptance.

RESUMEN

AIM: To determine if consumers and clinicians believe intelligence or health outcomes are more important long-term outcomes for babies born preterm. METHODS: Prospective, online survey of six outcomes ranked using a hierarchy ladder, Likert scale and a hypothetical scenario: education (complete secondary school); longevity (70 years of age or more); money (sufficient for rent and food); normal weight; good health and intelligence. Participants were clinicians taking care of preterm babies, parents of preterm babies, ex-preterm adults and adult controls. RESULTS: The survey was completed by 145 participants (35 controls, 36 clinicians, 39 parents and 35 ex-preterm adults). Health was the most frequently top-ranked variable on the hierarchy ladder (health; 99/145 (68.3%), money; 17/145 (11.7%), longevity; 10/145 (6.9%), education; 8/145 (5.5%), normal weight; 6/145 (4.1%), intelligence; 5/145 (3.4%), P < 0.0001), with no statistical difference between the groups. On a 5-point Likert scale, participants were most likely to agree that sufficient money, health and finishing secondary school were important for preterm babies to have a good life (mean (SD): money 4.43 (0.81); health 4.39 (0.72); education 4.37 (0.81); normal weight 4.10 (0.81); intelligence 4.03 (0.94); longevity 4.01 (1.07), P < 0.0001). In the scenario, the option of an ex-preterm adult having a healthy life with low socio-economic status (SES), was preferred over high SES with an unhealthy life (p < 0.0001). CONCLUSIONS: Health was perceived as the most important long-term outcome for preterm babies. Future research should prioritise good health outcomes for babies born preterm.

RESUMEN

INTRODUCTION: Clinical and laboratory studies demonstrate that placebo and nocebo effects influence various symptoms and conditions after the administration of both inert and active treatments. OBJECTIVE: There is an increasing need for up-to-date recommendations on how to inform patients about placebo and nocebo effects in clinical practice and train clinicians how to disclose this information. METHODS: Based on previous clinical recommendations concerning placebo and nocebo effects, a 3-step, invitation-only Delphi study was conducted among an interdisciplinary group of internationally recognized experts. The study consisted of open- and closed-ended survey questions followed by a final expert meeting. The surveys were subdivided into 3 parts: (1) informing patients about placebo effects, (2) informing patients about nocebo effects, and (3) training clinicians how to communicate this information to the patients. RESULTS: There was consensus that communicating general information about placebo and nocebo effects to patients (e.g., explaining their role in treatment) could be beneficial, but that such information needs to be adjusted to match the specific clinical context (e.g., condition and treatment). Experts also agreed that training clinicians to communicate about placebo and nocebo effects should be a regular and integrated part of medical education that makes use of multiple formats, including face-to-face and online modalities. CONCLUSIONS: The current 3-step Delphi study provides consensus-based recommendations and practical considerations for disclosures about placebo and nocebo effects in clinical practice. Future research is needed on how to optimally tailor information to specific clinical conditions and patients' needs, and on developing standardized disclosure training modules for clinicians.

RESUMEN

Although patient acceptance is important for biosimilar adoption and reducing healthcare costs, many patients perceive biosimilars to be unsafe and have concerns about switching. Studies show that patients' characteristics influence negative perceptions toward generic drugs, but little research has explored biosimilar acceptance. This study examines which demographic and psychological characteristics are associated with patients' safety perceptions and concerns about switching to biosimilars. Ninety-six patients taking bio-originators for rheumatic conditions (65% for rheumatoid arthritis) completed the Brief Illness Perceptions Questionnaire, Beliefs about Medicines Questionnaire and Perceived Sensitivity to Medicines Scale. Demographic factors, information seeking, concerns about switching and safety perceptions were also assessed. Pearson's correlations and hierarchical linear regressions were conducted to explore whether patient characteristics are associated with perceptions of biosimilars. Negative safety perceptions were associated with being female, short-term bio-originator use, illness beliefs, seeking health information online, high perceived sensitivity to medicines and negative beliefs about medicines. Only being female (ß = 0.24, P = 0.02) was independently associated. More concerns about switching were associated with being female, illness beliefs, high perceived sensitivity to medicines, information-seeking behaviours and preferring innovator drugs. Seeking health information online (ß = 0.20, P = 0.04), preferring innovator drugs (ß = 0.29, P = 0.004) and stronger emotional responses (ß = 0.26, P = 0.01) were independently associated. Perceived bio-originator effectiveness was inversely associated with preferring biosimilars (rs= - 0.33, P < 0.001). Patients who have stronger emotional responses to their condition, are females, seek health information online and prefer innovator drugs that have more negative perceptions about biosimilars. Experiences with bio-originators influence attitudes towards switching.

RESUMEN

BACKGROUND: Exacerbated parental stress during a stay in the neonatal intensive care unit can negatively impact the development of the hospitalized infant, strain the dyadic relationship and put parents at risk for poor mental health. It is therefore important to identify risk factors of stress throughout the duration of a hospitalization. This longitudinal study aimed to investigate sources of stress for mothers and fathers who had a baby in the neonatal special care unit. METHODS: Parents of 57 singletons and 11 twins (68 infants) admitted to a neonatal special care unit (46% for prematurity) were recruited. Sixty-four mothers and 20 fathers were assessed at admission, and 60 mothers and 16 fathers at discharge. Participants reported their satisfaction with hospital information and completed the Perceived Stress Scale, the Brief Illness Perception Questionnaire and the Dyadic Adjustment Scale. RESULTS: Parents demonstrated similar stress trajectories, with stress on average declining over time. Higher maternal stress at admission was associated with a belief that the baby's illness would have a longer timeline, lower perceptions of treatment efficacy and lower satisfaction with the information received from medical staff. Younger age and lower levels of education predicted higher maternal stress at discharge. Fathers had higher stress at discharge when they were older, had a baby born at younger gestation and felt they had less control. At admission, information satisfaction was positively associated with parental beliefs about treatment efficacy and understanding the infant's condition. At discharge, information satisfaction was negatively associated with beliefs about illness severity and the likely time frame of the illness. CONCLUSION: The findings highlight that parents' perceptions of their baby's illness and treatment at admission and discharge have a significant association with stress. Clinical staff can use these factors to identify parents who are at risk of exhibiting a greater level of stress over the hospitalization period.

RESUMEN

Placebo effects constitute a major part of treatment success in medical interventions. The nocebo effect also has a major impact, as it accounts for a significant proportion of the reported side effects for many treatments. Historically, clinical trials have aimed to reduce placebo effects; however, currently, there is interest in optimizing placebo effects to improve existing treatments and in examining ways to minimize nocebo effects to improve clinical outcome. To achieve these aims, a better understanding of the psychological and neurobiological mechanisms of the placebo and nocebo response is required. This review discusses the impact of the placebo and nocebo response in health care. We also examine the mechanisms involved in the placebo and nocebo effects, including the central mechanism of expectations. Finally, we examine ways to enhance placebo effects and reduce the impact of the nocebo response in clinical practice and suggest areas for future research.

RESUMEN

Non-adherence remains the largest cause of treatment failure to antiretroviral therapy (ART). Despite having the largest HIV pandemic, few successful adherence interventions have been conducted in South Africa. Active visualisation is a novel intervention approach that may help effectively communicate the need for consistent adherence to ART. The current study tested an active visualisation intervention in a sample of non-adherent patients. 111 patients failing on first- or second-line ART were recruited from two sites in the Western Cape, South Africa. Participants were randomly allocated to receive the intervention or standard care (including adherence counselling). The primary outcome was adherence as measured by plasma viral load (VL). There was a clinically significant difference (p = 0.06) in VL change scores between groups from baseline to follow-up, where the intervention had a greater decrease in log VL (Madj = - 1.92, CI [- 2.41, - 1.43), as compared to the control group (Madj = - 1.24, [- 1.76, - 0.73]). Participants in the intervention group were also significantly more likely to have a 0.5 log improvement in VL at follow-up ([Formula: see text] = 4.82, p = 0.028, ɸ = 0.28). This study provides initial evidence for the utility of this novel, brief intervention as an adjunct to standard adherence counselling, for improving adherence to ART.

RESUMEN

Background: Open-label placebos are a novel treatment option, in which participants take placebos with full knowledge that they do not contain active medicine. Open-label placebo treatments have been shown to result in patient-reported symptom improvements, but they have not been tested on objectively measurable physiological outcomes such as wound healing. Purpose: The current study aimed to determine whether open-label placebos improved wound healing in punch biopsy wounds compared with no treatment. Methods: In a randomized controlled trial, 70 participants (mean age 27.6 ± 10.1, 58 female) were provided with information about the beneficial effects of placebos and given a 4 mm punch biopsy wound. Participants were then randomized to either an open-label placebo intervention (two placebo tablets twice a day for 10 days) or a no-treatment control group. Wounds were photographed at 7 days and 10 days to determine reepithelialization of the wound surface. Results: No significant differences were observed between the open-label placebo and control conditions in the percentage of wound area healed or for the number of participants with fully reepithelialized wounds at 7 days (placebo 7/32 wounds healed, control 10/33 wounds healed, (χ2[1, N = 65] = 0.60, p = .440, φ = 0.10) and 10 days after wounding (placebo 17/32, control 25/33 wounds healed (χ2[1, N = 65] = 3.64, p = .056, φ = 0.24). Conclusions: Open-label placebo treatment does not improve the healing rate of wounds. Open-label placebos may be beneficial for subjective patient-reported outcomes but do not influence wound healing. Australian New Zealand Clinical Trials Registration: ACTRN12616000411448.

RESUMEN

Background: Social modeling has the capacity to shape treatment outcomes, including side effects. Purpose: This study investigated the influence of social modeling of treatment side effects, gender, and participant empathy, on side effects of a placebo treatment. Methods: Ninety-six participants (48 females) completed a study purportedly investigating the influence of modafinil (actually placebo) on alertness and fatigue. The participants were randomly seated with a male or female confederate and saw this confederate report experiencing side effects or no side effects. Participant empathy was assessed at baseline. Changes in modeled and general symptoms, and misattribution of symptoms, were assessed during the session and at 24-hr follow-up. Results: During the experimental session, seeing side effect modeling significantly increased modeled symptoms (p = .023, d = 0.56) but not general or misattributed symptoms. Regardless of modeling condition, female participants seated with a female model reported significantly more general symptoms during the session. However, response to social modeling did not differ significantly by model or participant gender. At follow-up, the effect of social modeling of side effects had generalized to other symptoms, resulting in significantly higher rates of modeled symptoms (p = .023, d = 0.48), general symptoms (p = .013, d = 0.49), and misattributed symptoms (p = .022, d = 0.50). The experience of modeled symptoms in response to social modeling was predicted by participants' levels of baseline empathy. Conclusions: Social modeling of symptoms can increase the side effects following treatment, and this effect appears to generalize to a broader range of symptoms and symptom misattribution over time. Higher baseline empathy seems to increase response to social modeling.

RESUMEN

Background: Previous research has shown a link between low positive affect and mortality, but questions remain about how positive affect is related to mortality and how this differs by gender and age. Purpose: To investigate the relationships between positive affect, negative affect, and mortality in a general population sample, and to examine whether these relationships were related to age, sex, or cause-specific mortality. Methods: We used data from 5,554 Norwegian participants aged 47-49 and 71-74 years who completed the Positive and Negative Affect Schedule (PANAS) and also provided data on demographics, health behaviors, and physical health as part of the Hordaland Health Study. The primary outcome was mortality after an average follow-up period of 16.5 years. Results: Participants in the lowest positive affect tertile had a near twofold increased mortality risk, compared to those in the highest positive affect tertile. This association was driven primarily by the PANAS "active" item and persisted, even after controlling for activity-related confounds and other positive affect items. No significant associations were found between negative affect and mortality. The relationship between positive affect and mortality was not significantly attenuated by age or sex. Although low positive affect was associated with an increased risk of mortality, it was not related to a specific cause of death. Conclusions: Low positive affect was significantly associated with mortality risk. The relationship was driven by the PANAS active item and not associated with cause-specific mortality. Findings suggest future research should examine the association between feeling inactive, sedentary behavior, and subsequent mortality.

RESUMEN

PURPOSE: Numerous studies have documented that lower socioeconomic status (SES) is associated with increased mental health problems in children. One proposed pathway for this association has been differential exposure to accumulated risk factors in children of lower SES. The aim of the current study was to investigate the socioeconomic distribution of exposure to negative life events and family stress and to examine the direct and interactive association between lower SES and exposure to life events and family stress in relation with mental health problems. METHODS: Using cross-sectional data from the second wave of the Bergen Child Study (conducted in 2006), the current study investigated the association between lower SES and exposure to negative life events, family life stressors, and mental health problems in a sample of 2043 Norwegian 11-13 years and their parents. Information about mental health was self-reported by the children using the Strengths and Difficulties Questionnaire, whereas information about SES and exposure to negative life events and family stressors were provided by their parents. RESULTS: The findings showed that lower SES was associated with more symptoms of emotional-, conduct-, hyperactivity/inattention-, and peer problems and that exposure to life events and family stress explained some of this association (10-29% of the total effects). CONCLUSIONS: Low SES and higher prevalence of negative life events and family stressors were associated with more symptoms of mental health problems. Overall, the effect sizes were smaller than previous investigations (f 2s = 0.015-0.031), perhaps suggesting a buffering effect of the social safety net in place in Norway.

RESUMEN

AIM: It has been increasingly recognised that family-centred care (FCC) is associated with enhanced well-being for both parents and infants in paediatric settings, including the neonatal intensive care unit (NICU). Over the past 4 years, our NICU has increasingly adopted a collaborative philosophy of care. The purpose of the study was to examine parental experiences of FCC during both the admission and discharge time points in order to examine differences in parents' experiences and identify areas for improvement. METHODS: We conducted interviews at two time points (admission and discharge) with 83 parents (mothers and fathers) of premature and medically fragile infants and analysed the data using thematic analysis. RESULTS: Three key themes (and sub-themes) were identified: disempowerment, hierarchy between parents and staff and the father's peripheral role. The themes were equally prevalent across admission and discharge. CONCLUSIONS: The challenges relating to FCC reported by parents at both admission and discharge represent some of the key barriers that parents still face in terms of being truly involved in the care of their infant in the NICU. Similar themes at both time points suggest that parents need equal amounts of support during their stay in NICU, irrespective of the level of care the infant is receiving and whether they are approaching discharge. Implications for improving FCC more generally are discussed.

RESUMEN

BACKGROUND: Placebo effects contribute substantially to outcome in most fields of medicine. While clinical trials typically try to control or minimize these effects, the potential of placebo mechanisms to improve outcome is rarely used. Patient expectations about treatment efficacy and outcome are major mechanisms that contribute to these placebo effects. We aimed to optimize these expectations to improve outcome in patients undergoing coronary artery bypass graft (CABG) surgery. METHODS: In a prospective three-arm randomized clinical trial with a 6 month follow-up, 124 patients scheduled for CABG surgery were randomized to either a brief psychological pre-surgery intervention to optimize outcome expectations (EXPECT); or a psychological control intervention focusing on emotional support and general advice, but not on expectations (SUPPORT); or to standard medical care (SMC). Interventions were kept brief to be feasible with a heart surgery environment; "dose" of therapy was identical for both pre-surgery interventions. Primary outcome was disability 6 months after surgery. Secondary outcomes comprised further clinical and immunological variables. RESULTS: Patients in the EXPECT group showed significantly larger improvements in disability (-12.6; -17.6 to -7.5) than the SMC group (-1.9; -6.6 to +2.7); patients in the SUPPORT group (-6.7; -11.8 to 1.7) did not differ from the SMC group. Comparing follow-up scores and controlling for baseline scores of EXPECT versus SUPPORT on the variable disability only revealed a trend in favor of the EXPECT group (P = 0.09). Specific advantages for EXPECT compared to SUPPORT were found for mental quality of life and fitness for work (hours per week). Both psychological pre-surgery interventions induced less pronounced increases in pro-inflammatory cytokine concentrations reflected by decreased interleukin-8 levels post-surgery compared to changes in SMC patients and lower interleukin-6 levels in patients of the EXPECT group at follow-up. Both pre-surgery interventions were characterized by great patient acceptability and no adverse effects were attributed to them. Considering the innovative nature of this approach, replication in larger, multicenter trials is needed. CONCLUSIONS: Optimizing patients' expectations pre-surgery helps to improve outcome 6 months after treatment. This implies that making use of placebo mechanisms has the potential to improve long-term outcome of highly invasive medical interventions. Further studies are warranted to generalize this approach to other fields of medicine. TRIAL REGISTRATION: Ethical approval for the study was obtained from the IRB of the Medical School, University of Marburg, and the trial was registered at ( NCT01407055 ) on July 25, 2011.

RESUMEN

BACKGROUND: Anti-vaccination attitudes are important predictors of vaccination behavior. Existing measures of vaccination attitudes focus on specific age groups and/or particular vaccines; a more comprehensive measure would facilitate comparisons across studies. PURPOSE: The aim of this study was to develop a short measure of general vaccination attitudes and establish its reliability and validity. METHODS: Two studies were conducted using the VAX scale. For Study 1, participants were 409 individuals (53% female), with a mean age of 34.5 years. For Study 2, participants were 92 individuals (67% female) with a mean age of 28.6. Participants answered paper-and-pencil questions about their attitudes toward vaccines, prior and expected-future vaccination behaviors, perceived sensitivity to medicines, online behavior, and basic demographic information. Exploratory and confirmatory factor analyses were conducted with correlations and t tests then used to assess the scale's reliability and validity. RESULTS: Four distinct but correlated vaccine attitudes were identified: (1) mistrust of vaccine benefit, (2) worries about unforeseen future effects, (3) concerns about commercial profiteering, and (4) preference for natural immunity. These factors were significantly related to prior vaccination behavior, future intentions to obtain recommended vaccinations, perceived sensitivity to medicines, and the tendency to obtain health information online. CONCLUSIONS: The VAX scale provides an efficient method for identifying those with vaccination resistance, and the four subscales enable a more nuanced understanding of the nature of those views. It should be noted, however, that the strong correlations amongst the four subscales suggest that interventions should target all four attitude areas, and it remains to be seen whether differential emphasis across the four areas is warranted.
