RESUMO
BACKGROUND: In April 2020, two independent clinical trials to assess SARS-CoV-2 prophylaxis strategies among health care workers were initiated at our hospital: MeCOVID (melatonin vs placebo) and EPICOS (tenofovir disoproxil/emtricitabine vs hydroxychloroquine vs combination therapy vs placebo). OBJECTIVE: This study aimed to evaluate the reasons why health care workers chose to participate in the MeCOVID and EPICOS trials, as well as why they chose one over the other. METHODS: Both trials were offered to health care workers through an internal news bulletin. After an initial screening visit, all subjects were asked to respond to a web-based survey. RESULTS: In the first month, 206 health care workers were screened and 160 were randomized. The survey participation was high at 73.3%. Health care workers cited "to contribute to scientific knowledge" (n=80, 53.0%), followed by "to avoid SARS-CoV-2 infection" (n=33, 21.9%) and "the interest to be tested for SARS-CoV-2" (n=28, 18.5%), as their primary reasons to participate in the trials. We observed significant differences in the expected personal benefits across physicians and nurses (P=.01). The vast majority of volunteers (n=202, 98.0%) selected the MeCOVID trial, their primary reason being their concern regarding adverse reactions to treatments in the EPICOS trial (n=102, 69.4%). CONCLUSIONS: Health care workers' reasons to participate in prophylaxis trials in an acute pandemic context appear to be driven largely by their desire to contribute to science and to gain health benefits. Safety outweighed efficacy when choosing between the two clinical trials.

Antenatal progesterone prevents preterm birth (PTB) in women with a short cervix or prior PTB in daily vaginal or weekly injectable formulations, respectively. Neither has been tested for the indication of maternal HIV, which is associated with an elevated risk of PTB. The Vaginal Progesterone (VP) Trial was a pilot feasibility study of VP to prevent HIV-related PTB in Lusaka, Zambia. Using mixed methods, we concurrently evaluated the acceptability of the trial and the study product among participants. Over a 1-year period, we enrolled 140 pregnant women living with HIV into a double-masked, placebo-controlled, randomized trial of daily self-administered VP or placebo. We administered an endline questionnaire to all participants and conducted in-depth interviews with 30 participants to assess barriers and facilitators to uptake and retention in the trial and to study product adherence. All interviews were audiotaped, transcribed, translated into English as needed, and independently coded by two analysts to capture emerging themes. Of 131 participants who completed the questionnaire, 128 (98%) reported that nothing was difficult when asked the hardest part about using the study product. When given a hypothetical choice between vaginal and injectable progesterone, 97 (74%) chose vaginal, 31 (24%) injectable, and 3 (2%) stated no preference. Most interviewees reported no difficulties with using the study product; others cited minor side effects and surmountable challenges. Strategies that supported adherence included setting alarms, aligning dosing with antiretrovirals, receiving encouragement from friends and family, sensing a benefit to their unborn baby, and positive feedback from study staff. Participants who reported preference of a vaginal medication over injectable described familiarity with the vaginal product, a fear of needles and resulting pain, and inconvenience of a weekly clinic visit. Those who would prefer weekly injections cited fewer doses to remember. Perceived barriers to study participation included mistrust about the motivations behind research, suspicion of Satanism, and futility or possible harm from a placebo. We report key influences on acceptability of a randomized trial of VP to prevent PTB among HIV-infected women in Zambia, which should inform methods to promote uptake, adherence, and retention in a full-scale trial.

BACKGROUND: Cognitive Training (CT) has demonstrated some benefits to cognitive and psychosocial function in Mild Cognitive Impairment (MCI) and early dementia, but the certainty related to those findings remains unclear. Therefore, understanding the mechanisms by which CT improves cognitive functioning may help to understand the relationships between CT and cognitive function. The purpose of this review was to identify the evidence for neuroimaging outcomes in studies of CT in MCI and early Alzheimer's Disease (AD). METHODS: Medline, Embase, Web of Science, PsycINFO, CINAHL, and The Cochrane Library were searched with a predefined search strategy, which yielded 1778 articles. Studies were suitable for inclusion where a CT program was used in patients with MCI or AD, with a structural or functional Magnetic Resonance Imaging (MRI) outcome. Studies were assessed for quality using the Downs and Black criteria. RESULTS: A total of 19 studies met the inclusion criteria. Quality of the included studies was variable and there was significant heterogeneity for studies included in this review. Task activation was generally increased post-training, but functional connectivity was both increased and decreased after training. Results varied by diagnosis, type of CT program, and brain networks examined. No effects were seen on hippocampal volumes post-training, but cortical thickening and increased grey matter volumes were demonstrated. CONCLUSIONS: CT resulted in variable functional and structural changes in dementia, and conclusions are limited by heterogeneity and study quality. Larger, more robust studies are required to correlate these findings with clinical benefits from CT.

OBJECTIVE: To explore the delivery of home and hospital management at diagnosis of type 1 diabetes in childhood and any impact this had on health professionals delivering care. METHODS: This qualitative study was undertaken as part of the Delivering Early Care in Diabetes Evaluation randomized controlled trial where participants were individually randomized to receive initiation of management at diagnosis, to home or hospital. Semi-structured telephone interviews were planned with a purposive sample of health professionals involved with the delivery of home and hospital management, to include consultants, diabetes and research nurses, and dieticians from the eight UK centres taking part. The interview schedule focused on their experiences of delivering the two models of care; preferences, impact, and future plans. Data were subject to thematic analysis. RESULTS: Twenty-two health professionals participated, represented by consultants, diabetes and research nurses, and dieticians. Overall, nurses preferred home management and perceived it to be beneficial in terms of facilitating a unique opportunity to understand family life and provide education to extended family members. Nurses described a special bond and lasting relationship that they developed with the home managed children and families. Consultants expressed concern that it jeopardized their relationship with families. Dieticians reported being unable to deliver short bursts of education to families in the home managed arm. All health professionals were equally divided over which was logistically easier to deliver. CONCLUSIONS: A hybrid approach, of a brief stay in hospital and early home management, offers a pragmatic solution to the advantages and challenges presented by both systems.

OBJECTIVES: Given the disparity that exists in enrollment of minorities to oncology clinical trials, the objective of our study was to assess whether race is associated with willingness to participate in gynecologic oncology clinical trials in a rural Southern academic medicine setting. Our secondary aim was to determine whether willingness to participate is impacted by an educational intervention. METHODS: A single institution prospective survey study was performed at an academic medical center. Women presenting to the gynecologic oncology clinic with a current or prior diagnosis of gynecologic malignancy were approached to participate. The validated Attitudes to Randomized Trials Questionnaire (ARTQ) assessed willingness to participate in clinical trials. Relevant demographic and clinical data were abstracted. Characteristics were compared between those willing and unwilling to participate in clinical trials with a chi-square test for categorical variables and Wilcoxon rank sum tests for continuous data. RESULTS: We enrolled 156 participants (50% White, 50% non-White) from May 2017 to January 2018. The minority group included 35% non-Hispanic Black, 9% Hispanic, 4% Asian, and 2% other. Median age was 63 years with endometrial cancer being the most common diagnosis (48%). On initial screen, only 35% were willing to participate in a clinical trial. Willingness to participate did not differ between race, age, marital status, education level, cancer type, stage, or mode of treatment. Rates improved to 82% after being provided additional educational information. Following education, White women and those with more education were significantly more willing to participate in clinical trials than their minority and less educated counterparts. CONCLUSIONS: Willingness to participate improved among all sub-categories following an educational intervention. The increase in willingness was less robust among racial and ethnic minorities, suggesting that different tools are needed for recruitment of minorities to gynecologic oncology clinical trials.

Background The number of global clinical trials is increasing. Recruitment rate in clinical trials is a challenging task that affects sample size, power of the study, and adequate representation of the targeted population. An understanding of the worries and reasons why patients may refrain from participation in trials may lead to improved enrollment rates. Objectives To assess the rate of patients who are willing to participate in clinical trials, and aspects that might have an impact on the patients' willingness to participate. Setting Government tertiary hospital in Jordan. Methods This is a cross-sectional study. Patients were interviewed by pharmacists in different clinics in a tertiary hospital and information was collected using a data collection sheet. Main outcome measure Factors that might predict the inclination of a patient to participate in clinical trials, and the rate of willingness to participation in randomized controlled trials in cancer patients compared to non-cancer patients. Results A total of 1193 participants were enrolled in the study, one hundred and thirty-five participants (11.3%) had cancer and 80% of the participants had at least one chronic medical condition. Majority of patients (n = 882, 73.9%) believed that trials were safe and 1106 (92.7%) patients thought they were important. Age, education level, income, having cancer or any chronic medical condition, and degree of control of chronic diseases were statistically significant predictors of the willingness of patients to participate in trials. Patients with cancer had a higher rate of acceptance to participation in randomized controlled trials compared to non-cancer patients, 80.0% versus 62.4%, p value < 0.001. Conclusion In general, almost two-thirds of patients were willing to participate in clinical trials, with a higher rate in cancer patients. Factors such as education level, income, and extent of control of medical conditions that might refrain patients from enrollment in trials will lower recruitment rate and must be addressed and taken into consideration before launching clinical trials.

Studies show that conservative management in acute uncomplicated appendicitis (AUA) is an alternative to surgery. This study aims to determine factors affecting parental preference in management of AUA and their decision for research participation. We conducted surveys on parents whose children were admitted with suspicion of appendicitis but later confirmed not to have appendicitis. Information on appendicectomy versus conservative treatment with antibiotics was provided using a fixed script and standard information leaflet. Questionnaires covered factors influencing decisions, opinions regarding research, treatment preference and demographic data. We excluded parents not fluent in English. Of 113 respondents, 71(62.8%) chose antibiotics, 39(34.5%) chose appendicectomy, and 3(2.7%) had no preference. Reasons given for choosing antibiotics were fear of surgical risks and preferring less invasive treatment. Those choosing appendicectomy expressed preference for definitive treatment and fear of recurrence. Majority were against randomisation (n = 89, 78.8%) and blinding (n = 90, 79.7%). Over half found difficulty involving their child in research (n = 65, 57.5%). Most thought that research is important (66.4%) and beneficial to others (59.3%). Parents who perceived their child as healthy found research riskier (p = 0.039). Educated parents were more likely to find research beneficial to others (p = 0.012) but less accepting of randomisation (p = 0.001).Conclusion: More parents appear to prefer conservative treatment for acute uncomplicated appendicitis. Researchers must consider parental concerns regarding randomisation and blinding.What is Known:⢠Conservative management of acute uncomplicated appendicitis in paediatric patients is safe and effective, sparing the child the need for an operation; however, neither conservative nor surgical management is proven to be superior.⢠Randomised controlled trials provide the highest level of evidence, but it is challenging to recruit paediatric patients as participants in such clinical trials.What is New:⢠More parents prefer conservative management of uncomplicated appendicitis over surgical management for their children due to fear of surgical risks and complications⢠Randomisation in trial design is significantly associated with a parent's decision to reject their child's participation in a clinical trial.

The COVID-19 pandemic has magnified the importance of clinical trials for finding a safe and effective vaccine to protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19. Although communication about vaccines and vaccine hesitancy were challenges long before COVID-19, the twin facts of a pandemic and an "infodemic" of health information, misinformation, and disinformation have raised new challenges for vaccine-related communication and decision-making. The goal of this commentary is to highlight strategies to improve communication and decision-making for adults considering participation in COVID-19 vaccine clinical trials. First, I present a general conceptual model for clinical trial participation that can be applied to various vaccine and other clinical trial contexts. Next, I introduce the ASK (Assume, Seek, Know) approach for enhancing clinical trial participation: (1) assume that all patients will want to know their options, (2) seek the counsel of stakeholders, and (3) know your numbers. The ideas presented in this commentary are intended to enhance vaccine-specific clinical trial communication, decision-making, and literacy, while dually offering strategies and resources that may help reduce vaccine hesitancy and increase vaccine uptake over time.

BACKGROUND: Interventions that enable people to remain in their own home as they age are of interest to stakeholders, yet detailed information on effective interventions is scarce. Our objective was to systematically search and synthesise evidence for the effectiveness of community-based, aged care interventions in delaying or avoiding admission to residential aged care. METHOD: Nine databases were searched from January 2000 to February 2018 for English publications. Reference lists of relevant publications were searched. The databases yielded 55,221 citations and 50 citations were gleaned from other sources. Where there was sufficient homogeneity of study design, population, intervention and measures, meta-analyses were performed. Studies were grouped by the type of intervention: complex multifactorial interventions, minimal/single focus interventions, restorative programs, or by the target population (e.g. participants with dementia). RESULTS: Data from 31 randomised controlled trials (32 articles) that met our inclusion criteria were extracted and analysed. Compared to controls, complex multifactorial interventions in community aged care significantly improved older adults' ability to remain living at home (risk difference - 0.02; 95% CI -0.03, - 0.00; p = 0.04). Commonalities in the 13 studies with complex interventions were the use of comprehensive assessment, regular reviews, case management, care planning, referrals to additional services, individualised interventions, frequent client contact if required, and liaison with General Practitioners. Complex interventions did not have a significantly different effect on mortality. Single focus interventions did not show a significant effect in reducing residential aged care admissions (risk difference 0, 95% CI -0.01, 0.01; p = 0.71), nor for mortality or quality of life. Subgroup analysis of complex interventions for people with dementia showed significant risk reduction for residential aged care admissions (RD -0.05; 95% CI -0.09, -0.01; p = 0.02). Compared to controls, only interventions targeting participants with dementia had a significant effect on improving quality of life (SMD 3.38, 95% CI 3.02, 3.74; p < 0.000001). CONCLUSIONS: Where the goal is to avoid residential aged care admission for people with or without dementia, there is evidence for multifactorial, individualised community programs. The evidence suggests these interventions do not result in greater mortality and hence are safe. Minimal, single focus interventions will not achieve the targeted outcomes.

AIM OF THE STUDY: The internal validity of double blinding in randomised placebo-controlled trials (RCTs) has become a target of criticism. The goal of this study was to investigate (a) how accurately the patients and their treating physicians were able to guess their assigned treatment, and (b) predictors for an accurate guess. METHODS: Data on treatment estimation from patients (n = 382) and their physicians (n = 358 guesses) in an RCT investigating the role of adjunct prednisone for community-acquired pneumonia in a tertiary care setting were analysed. At discharge, patients and their physicians had to guess whether they had been assigned to the prednisone or to the placebo group. The alternative possibility was “uncertain”. Percentages and confidence intervals (CIs) were calculated for the proportion of patients guessing correctly. Chance finding was defined as having 50% or less correct guesses. To test for predictors for prednisone treatment guess, a mixed effects logistic regression model was performed. RESULTS: In the prednisone group, 28.9% (55/190; 95% CI 22.6–36.0%) of the patients made a correct guess and the majority (61.6%, 117/190) was uncertain. In the placebo group, 13.0% (25/192; 95% CI 8.8–18.8%) guessed correctly, with the majority being uncertain (69.8%, 134/192). Physicians guessed correctly in 48.3% (87/180, 95% CI 40.8–55.9%) of cases in the prednisone group and in 66.3% (118/178, 95% CI 58.8–73.2%) of cases in the placebo group, which was above chance for the placebo group. The physicians were uncertain in 21.7% (39/180) of cases in the prednisone group, and in 15.2% (27/178) of cases in the placebo group. Significant predictors for guessing prednisone were the occurrence of hyperglycaemia (odds ratio [OR] 3.77, 95% CI 2.39–5.95; p<0.001) and a shorter time to clinical stability (OR 0.95, 95% CI 0.91–0.99; p = 0.02). CONCLUSIONS: We confirmed that patient blinding was achieved in this study. Physicians made correct guesses more often than patients. Treatment estimation by both patients and physicians was led not only by the expectations of treatment effects of the study drug but also by known side effects of prednisone. Trial registration no.: NCT00973154  .

BACKGROUND: In recent years, several reviews have addressed the effectiveness of dance therapy in dementia, healthy older adults, or the elderly in general. However, reviews regarding the effect of this therapy exclusively on patients diagnosed with Alzheimer's disease have not been found. OBJECTIVE: The purpose of this study is to review the available literature describing clinical trials which explore the effects of dancing on psychological and physical outcomes, functionality, cognitive function, and quality of life in patients diagnosed with Alzheimer's disease. In addition, this review aims to assess the quality of studies that perform dance therapy interventions in these patients. METHODS: This study is a systematic review of randomized and non-randomized clinical trials regarding the effect of intervention including a dancing activity in people diagnosed with Alzheimer's disease. RESULTS: In total, the evidence for this review rests on 12 studies with a total of 349 participants. The findings of this mini-review confirm the positive effect of dance therapy on physical and cognitive function, functionality, psychological outcomes, and quality of life in people with Alzheimer's disease. CONCLUSION: Most of the studies implementing dance as part of the therapeutic treatment has shown to improve or slow the worsening in the quality of life of patients with Alzheimer's disease and their caregivers. Future research focused on these patients should use a more exhaustive methodology and make a more detailed description of these kind of interventions.

BACKGROUND: There are limited data comparing the consistency of angina reporting by patients and clinicians. METHODS: We performed a retrospective analysis of data from the randomised Stent or Surgery (SoS) trial. The trial required reporting of angina using the Canadian Cardiovascular Society (CCS) classification by both patients and clinicians at baseline and twelve months. We compared paired observations to describe the magnitude and direction of differences in clinician and patient reporting. The difference in CCS grade was expressed as the clinician minus patient value. We also examined the proportion of trial subjects reported as being free from angina (CCSâ¯=â¯0) in clinician and patient reporting. RESULTS: Paired CCS data was available for 912 and 887 cases at baseline and 12â¯months respectively. At baseline, clinicians reported freedom from angina in a single case (1/912â¯=â¯0.1%) compared to 70/912 (7.7%) patients (Delta 7.6% 95% CI 5.8 to 9.3, Pâ¯≤0.001). At 12â¯months, the position was reversed, with clinicians reporting 639/887 (72%) angina free compared to 449/887 (50.6%) for patients (Delta -21.4 95% CI -17.1 to -25.8 Pâ¯≤â¯0.001). For the reported CCS grade at follow-up, the weighted linear kappa for overall agreement was 0.312. Discordant reporting involved the clinician suggesting less angina rather than more (36% v 8% of cases). CONCLUSIONS: These findings have implications for our perception of previous research which has, in the main, focussed on clinician reporting. This emphasises the importance of patient reporting and a need to better understand reasons for discordance.

BACKGROUND: There is a lack of well-designed randomized controlled trials (RCTs) to investigate the efficacy of psychological therapies for children in foster care with emotional and behavioural difficulties. Mentalization-based therapy (MBT) focuses on supporting the carer-child relationship by promoting reflective capacity. This study examined the feasibility and acceptability of an RCT of MBT, delivered in a family-format, for children who are in foster care in the UK. METHOD: Herts and Minds was a phase II, blinded feasibility RCT with follow-up of at 12 and 24 weeks post-randomisation. Participants were children (age 5-16) in foster care referred to a targeted mental health service, who had some level of difficulty as identified by the Strengths and Difficulties Questionnaire (SDQ). Aims were to assess: the feasibility of recruitment processes and study uptake; capacity to train mental health practitioners to deliver MBT to an acceptable level of treatment integrity; establish acceptability and credibility of MBT as an intervention for children in foster care; establish feasibility and acceptability to participants of conducting an RCT; and estimate the likely treatment efficacy effect size. Participants were randomly allocated to either MBT (n = 15) or Usual Clinical Care (UCC) (n = 21) individually or in sibling groups. A range of qualitative and quantitative data was gathered to assess feasibility. RESULTS: Feasibility was established with regard to: capacity to recruit participants to a study; capacity to train mental health practitioners to deliver MBT to an acceptable level of treatment integrity; acceptability and credibility of MBT; and feasibility and acceptability to participants of conducting an RCT. A number of issues made it difficult to estimate a likely treatment efficacy effect size. CONCLUSION: With modifications, it is feasible to run an RCT of MBT for children in foster care. Both the therapy and research design were acceptable to participants, but modifications may be needed regarding both the timing of assessments and the identification of appropriate primary outcome measures. Given the lack of evidenced based therapies for this population, such a trial would be a significant contribution to the field. Findings may be useful for other groups planning clinical trials of psychological therapies for children in foster care. TRIAL REGISTRATION: ISRCTN 90349442 . The trial was retrospectively registered on 6 May 2016.

In this paper, I suggest that placebo effects, as we know them today, should be understood as experimental phenomena, low-level regularities whose causal structure is grasped through particular experimental designs with little theoretical guidance. Focusing on placebo interventions with needles for pain reduction -one of the few placebo regularities that seems to arise in meta-analytical studies- I discuss the extent to which it is possible to decompose the different factors at play through more fine-grained randomized clinical trials. My sceptical argument is twofold. On the one hand, I argue that experiments alone are not enough to standardize interventions, and that it is necessary to include theories. On the other hand, I argue that the social interactions that seem to be part of placebo effects are difficult, if not impossible, to blind. Therefore, the measurement biases arising from the participants' reactivity to the experimental setup cannot be controlled for. Further decomposition of placebo effects requires a theoretical account of the existing experimental regularities that may guide further tests.

BACKGROUND: Some patients with major depression continue to demonstrate deficits in health-related quality of life (HRQL) following remission. No data exist, however, regarding HRQL in remitted psychotic depression. In this study, we aimed to characterize HRQL in patients with psychotic depression receiving controlled pharmacotherapy. METHODS: This is a secondary analysis of a randomized controlled trial studying continuation pharmacotherapy of psychotic depression. We compared participants' HRQL (measured using the SF-36) between baseline and remission and to population norms. We also compared SF-36 scores stratified by age and gender and examined the correlation between SF-36 scores and medical burden, depression score and neuropsychological performance in remission. RESULTS: SF-36 scores were significantly lower than population norms at baseline, but improved following remission to the level of population norms. Neither SF-36 scores nor magnitude of SF-36 improvement differed substantially between genders or between younger and older participants. In remission, depression scores were correlated with most SF-36 scales and medical burden was correlated with SF-36 scales measuring physical symptoms. Neuropsychological measures were generally not correlated with SF-36 scores. LIMITATIONS: This study was a secondary analysis not powered specifically to measure HRQL as an outcome variable and the SF-36 was the only HRQL measure used. CONCLUSIONS: Participants with remitted psychotic depression demonstrated levels of HRQL comparable to population norms, despite marked impairment in HRQL when acutely ill. This finding suggests that, when treated in a rigorous manner, many patients with this severe illness improve significantly from a clinical and HRQL perspective.

Clinical trial accrual is vital to advancing care. A single study elucidated demographic data correlating with glioma patients' clinical trial enrollment. However, it did not investigate the underlying decision-making process for non-participation. In this study, we seek to understand this key aspect of patient accrual. All notes for glioma patients seen by a single neuro-oncologist from July 2010 to May 2017 were examined for mention of clinical trial offerings. When a trial was declined, the patient's reasoning was recorded along with the following: diagnosis, KPS, extent of resection, age, gender, race, marital status, income group, religion, trial offered at initial visit versus subsequent, and distance from trial site. Of 279 consecutive glioma patients, 88 were eligible for and offered a clinical trial. Fifty-seven accepted (65%), and 31 (35%) declined participation (Fig. 1). Of those offered a clinical trial, patients with glioblastoma (GBM) were significantly more likely to accept (44 out of 57 (77%) vs. 13 out of 57 (23%), p =0.03). After we adjusted for gender and travel distance, GBM was the only significant predictor of clinical trial acceptance, with an odds ratio of 3.18 (95% CI 1.17, 8.61, p =0.02). Reasons cited for non-participation included: travel distance (39%), lack of interest (39%), visit frequency (16%), and fear of randomization (6%). This study clarified for the first time individual glioma patient rationale for non-participation and potential areas for improving enrollment. Allowing off-site treatment centers or telemedicine visits may entice rural patients to participate. Visit frequency should be carefully considered and minimized whenever possible. Further prospective study of rationale for non-participation may improve enrollment over time.

Rural-residing cancer patients often do not participate in clinical trials. Many patients misunderstand cancer clinical trials and their rights as participant. The purpose of this study is to modify a previously developed cancer clinical trials decision aid (DA), incorporating the unique needs of rural populations, and test its impact on knowledge and decision outcomes. The study was conducted in two phases. Phase I recruited 15 rural-residing cancer survivors in a qualitative usability study. Participants navigated the original DA and provided feedback regarding usability and implementation in rural settings. Phase II recruited 31 newly diagnosed rural-residing cancer patients. Patients completed a survey before and after using the revised DA, R-CHOICES. Primary outcomes included decisional conflict, decision self-efficacy, knowledge, communication self-efficacy, and attitudes towards and willingness to consider joining a trial. In phase I, the DA was viewed positively by rural-residing cancer survivors. Participants provided important feedback about factors rural-residing patients consider when thinking about trial participation. In phase II, after using R-CHOICES, participants had higher certainty about their choice (mean post-test = 3.10 vs. pre-test = 2.67; P = 0.025) and higher trial knowledge (mean percentage correct at post-test = 73.58 vs. pre-test = 57.77; P < 0.001). There was no significant change in decision self-efficacy, communication self-efficacy, and attitudes towards or willingness to join trials. The R-CHOICES improved rural-residing patients' knowledge of cancer clinical trials and reduced conflict about making a trial decision. More research is needed on ways to further support decisions about trial participation among this population.

IntroductionDespite consistently high discontinuation rates due to withdrawal of consent (WOC) and insufficient therapeutic effect (ITE) in schizophrenia trials, insight into the underlying factors contributing to poor satisfaction with treatment and dropout is limited. A better understanding of these factors could help to improve trial design and completion rates. METHODS: Using data from 1,136 trial participants with schizophrenia or schizoaffective disorder, we explored associations between predictor variables with (1) dropout due to WOC and ITE and (2) satisfaction with treatment among patients and investigators by means of hierarchic multiple regression analyses. RESULTS: ITE was associated with poor clinical improvement, poor investigator satisfaction with treatment, and poor patient insight into their own disease, whereas WOC only showed a meaningful association with poor patient satisfaction with treatment. Investigator satisfaction with treatment appeared most strongly associated with Positive and Negative Syndrome Scale (PANSS) positive factor endpoint scores, whereas patient satisfaction with treatment was best predicted by the endpoint score on the PANSS emotional distress factor. The occurrence of severe side effects showed no meaningful association to satisfaction with treatment among investigators and patients, and neither did a patient's experienced psychopathology, nor their self-rating of functional impairment. CONCLUSIONS: Whereas trial discontinuation due to ITE is associated with poor treatment effectiveness, a patient's decision to withdraw from an antipsychotic trial remains unpredictable and may occur even when the investigator observes a global clinical improvement and is satisfied with the treatment.

OBJECTIVE: We tested the hypothesis that participants who know the behavioral focus of a study and are thus aware that a particular behavior is being studied will modify that behavior, independently of any possible effect of assessment, thereby dismantling a Hawthorne effect into two putative components. STUDY DESIGN AND SETTING: We undertook a three-arm individually randomized trial online among students: group A (control) were told they were completing a lifestyle survey; group B were told the focus of the survey was alcohol consumption; and group C additionally answered 20 questions on their alcohol use and its consequences before answering the same lifestyle questions as Groups A and B. Nondrinkers were excluded, and all groups were aware they would be followed up after 1 month. RESULTS: Outcome data were obtained for 4,583 of 5,478 trial participants (84% follow-up rate). There were no differences between the three groups on primary (overall volume consumed) or secondary outcome measures (drinking frequency and amount per typical occasion) in the intervening 4 weeks. CONCLUSIONS: There is no evidence that any form of Hawthorne effect exists in relation to self-reported alcohol consumption online among university students in usual research practice. Attention to study contexts is warranted for investigating research participation effects.
