Selective Prevention

Abstract Background Prevention programs for cardiometabolic diseases (CMD), including cardiovascular disease, diabetes mellitus and chronic kidney disease are feasible, but evidence for the cost-effectiveness of selective CMD prevention programs is lacking. Response rates have an important role in effectiveness, but methods to increase response rates have received insufficient attention. The aim of the current study is to determine the feasibility and the success rate of a variety of response enhancing strategies to increase the participation in a selective prevention program for CMD. Methods The INTEGRATE study is a Dutch randomised controlled trial to assess the effectiveness and cost-effectiveness of a stepwise program for CMD prevention. During the INTEGRATE study we developed ten different response enhancing strategies targeted at different stages of non-response and different patient populations and evaluated these in 29 general practices. Results A face-to-face reminder by the GP increased the response significantly. Digital reminders targeted at patients with an increased CMD risk showed a positive trend towards participation. Sending invitations and reminders by e-mail generated similar response rates, but at lower costs and time investment than the standard way of dissemination. Translated materials, information gatherings at the practice, self-management toolkits, reminders by telephone, information letters, local media attention and SMS text reminders did not increase the response to our program. Conclusions Inviting or reminding patients by e-mail or during GPs consultation may enhance response rates in a selective prevention program for CMD. Different response-enhancing strategies have different patient target populations and implementation issues, therefore practice characteristics need to be taken into account when implementing such strategies.

Scientific Survey

Background. Survey instruments are valuable tools for research and provide insight into real-world practice and areas of knowledge deficits in ways that traditional observational studies and randomized trials cannot. Despite some experts espousing survey response rates ≥60% as valid, there is no consensus as to what an adequate response rate is for a scientific survey. Furthermore, little is known what effect the interaction of survey administration modality and response rate has on results. Objective. To compare the results of differing survey modalities (which typically feature different response rate ranges). Methods. A validated, 21-item survey assessing perceptions of, recommendations regarding, and usage of sunscreen was distributed to three samples of dermatologists using three different modalities: pen/paper via mail, online via email, and in real-time via an audience response system at a national conference. Results. Response rates varied widely by survey modality (30% mail, 9% email 95% live). However, dermatologists’ responses to individual survey questions were largely consistent across modalities, with a statistically significant difference seen for only three questions (recommending sunscreens based on cosmetic elegance, recommending sunscreens based on photostability, and recommending vitamin D supplementation as a means to avoid sun exposure.  Conclusions. In this study evaluating dermatologists’ perceptions of, recommendations for, and personal use of sunscreen, survey results were largely consistent across three different modalities (mail, email, live) despite widely variable response rates, from 9% to 95%. These results suggest that when a scientific survey sample is representative of the target population, minimum response rate and survey modality appear to have negligible impact on results.

A rise in fragility as a system approaches a tipping point may be sometimes estimated using dynamical indicators of resilience (DIORs) that measure the characteristic slowing down of recovery rates before a tipping point. A change in DIORs could be interpreted as an early warning signal for an upcoming critical transition. However, in order to be able to estimate the DIORs, observational records need to be long enough to capture the response rate of the system. As we show here, the required length of the time series depends on the response rates of the system. For instance, the current rate of anthropogenic climate forcing is fast relative to the response rate of some parts of the climate system. Therefore, we may expect difficulties estimating the resilience from modern time series. So far, there have been no systematic studies of the effects of the response rates of the dynamical systems and the rates of forcing on the detectability trends in the DIORs prior to critical transitions. Here, we quantify the performance of the resilience indicators variance and temporal autocorrelation, in systems with different response rates and for different rates of forcing. Our results show that the rapid rise of anthropogenic forcing to the Earth may make it difficult to detect changes in the resilience of ecosystems and climate elements from time series. These findings suggest that in order to determine with models whether the use of the DIORs is appropriate, we need to use realistic models that incorporate the key processes with the appropriate time constants.

Male Subjects

The effects of preliminary mail and telephone contacts on response rate and volunteer bias were studied. Advance telephone and mail contacts did not lead to significantly different response rates. The advance telephone contact, however, did give rise to volunteer bias: females volunteered significantly less often than male subjects. Preliminary mail contacts and political stance of the subjects were not related to the volunteering. Instead of advance telephone calls, the use of follow-up contacts seems to be preferable.

Rats, trained to press a lever for sucrose reward on a random interval (RI) schedule, were presented while lever-pressing with two stimuli, each associated with a different schedule of shock delivery: in the presence of one stimulus (Se), shock occurred on an RI schedule irrespective of the rat's behaviour; in the presence of the other (Sp) shocks were programmed by the same schedule but delivered only when the rat pressed the lever. Both stimuli suppressed lever-pressing. In addition, the rats developed significantly different response rates in the two stimuli, thus demonstrating a discrimination between response-contingent and response-independent shock. Group data showed faster responding in Se than in Sp, supporting the view that response-contingent shock produces greater suppression than response-independent shock. Individual animal analyses, however, demonstrated that this was the case in the majority of animals, but not in all. Response suppression was alleviated by amylobarbitone sodium (15 mg/kg) or chlordiazepoxide HCI (5 mg/kg); the latter drug alleviated suppression significantly more in Sp than Se and eliminated the difference between the response rates controlled by the two stimuli.

Abstract We examined the use of smoothing to enhance the detection of response coupling from the activity of different response systems. Three different types of moving average smoothers were applied to both simulated interbeat interval (IBI) and electrodermal activity (EDA) time series and to empirical IBI, EDA, and facial electromyography time series. The results indicated that progressive smoothing increased the efficiency of the detection of response coupling but did not increase the probability of Type I error. The power of the smoothing methods depended on the response characteristics. The benefits and use of the smoothing methods to extract information from psychophysiological time series are discussed.
