Assessing digital advertising exposure using a virtual experimental protocol.

ABSTRACT:

Introduction

The rapid increase in online public education campaigns underscores the need for a better understanding of the effects of exposure to digital advertising and targeted individual-level outcomes. The goal of this study is to develop a virtual experimental protocol to evaluate the dose-response effects of individual-level exposure to digital video ads on campaign outcomes in a naturalistic online browsing context.

Methods

Young adults aged 18-24 years (n = 221) completed three 5 min viewing sessions on a realistic mock-up of the YouTube mobile app over a period of 2 weeks, followed by a 10-min survey after the third session. Participants were randomized to view between 0 and 6 exposures of ads from an e-cigarette prevention campaign; respondents viewed a total of 2 ads per session, with 0 to 2 of those ads being non-skippable digital video ads from the campaign and/or a dummy ad. The video ads played prior to short YouTube videos. Outcomes measured were self-reported ad recognition, frequency of ad exposure, and main message knowledge.

Results

This study demonstrates a rapidly accessible virtual experimental protocol for evaluating the dose-response effects of digital advertising and individual-level outcomes. Five digital exposures of non-skippable video ads delivered via this platform over a 2-week period generated the highest ad recognition when there were up to six exposures. Higher exposure levels may be needed for message knowledge and ad-content-related effects.

Conclusion

This protocol can be extended to investigate dose-response effects and mechanisms of action of individual-level exposure to digital advertising for multiple campaign outcomes, including changes in knowledge, attitudes, and beliefs. Findings can inform evidence for adequate levels of digital exposure in public education campaigns.

Project description:ObjectiveGlobal trends, such as improving accessibility to healthcare services through the Internet, and the COVID-19 pandemic are among the driving factors in the adoption of digital health. This study hypothesized that digital solutions can reach and gather data from a large number of patients with trigeminal neuralgia (TN), a commonly misdiagnosed neuropathic facial pain syndrome, and quickly and fast-track their diagnosis by suggesting them to consult a neurologist. We developed an accessible digital screening tool based on patient symptoms and history to test this hypothesis and used social media advertisement to screen a general population for TN.MethodsThe standard diagnostic criteria, International Classification of Orofacial Pain, for facial pain is digitized as a web-based questionnaire that allows easy access to the evaluation for patients with suspected TN symptoms. Targeted search with relevant keywords and display campaigns on Google search engine and Facebook social media platform were used to reach large numbers of subjects. A report was autogenerated, which included a summary of a subject's symptoms, likely or likely not TN diagnosis, and information to seek appropriate medical assistance.ResultsThe website was live for seven weeks and generated 240 screening questionnaire submissions, with a total spending of $2482. Forty-four subjects (18.3%) that reported typical symptoms of TN experienced unilateral and episodic pain in one of the trigeminal nerve regions.ConclusionsWe have demonstrated the feasibility of social media advertisement and digitally screening a general population for TN, gathering valuable clinical data, such as pain characteristics, through a web-based questionnaire. Based on these data, patients with similar symptoms of TN are suggested to consult a neurologist for diagnosis. This study provides a framework for using digital screening tools to improve the healthcare experience of patients who would spend several months before finding appropriate diagnosis for their specific conditions.

Project description:BackgroundIsoflurane is used as an inhalation anesthetic in medical, paramedical, and veterinary practice. Epidemiological studies suggest an increased risk of miscarriages and malformations at birth related to maternal exposure to isoflurane and other inhalation anesthetics. However, these studies cannot be used to derive an occupational exposure level (OEL), because exposure was not determined quantitatively and other risk factors such as co-exposures to other inhalation anesthetics and other work-related factors may also have contributed to the observed adverse outcomes. The aim of this systematic review project is to assess all available evidence on the effects of isoflurane in studies of controlled exposures in laboratory animals to derive a health-based recommended OEL.MethodsA comprehensive search strategy was developed to retrieve all animal studies addressing isoflurane exposure from PubMed, EMBASE, and Web of Science. Title-abstract screening will be performed by machine learning, and full-text screening by one reviewer. Discrepancies will be resolved by discussion. We will include primary research in healthy, sexually mature (non human) vertebrates of single exposure to isoflurane. Studies describing combined exposure and treatments with > = 1 vol% isoflurane will be excluded. Subsequently, details regarding study identification, study design, animal model, and intervention will be summarized. All relevant exposure characteristics and outcomes will be extracted. The risk of bias will be assessed by two independent reviewers using an adapted version of the SYRCLE's risk of bias tool and an addition of the OHAT tool. For all outcomes for which dose-response curves can be derived, the benchmark dose (BMD) approach will be used to establish a point of departure for deriving a recommended health-based recommended OEL for 8 h (workshift exposure) and for 15 min (short-term exposure).DiscussionIncluded studies should be sufficiently sensitive to detect the adverse health outcomes of interest. Uncertainties in the extrapolation from animals to humans will be addressed using assessment factor. These factors are justified in accordance with current practice in chemical risk assessment. A panel of experts will be involved to reach consensus decisions regarding significant steps in this project, such as determination of the critical effects and how to extrapolate from animals to humans.Systematic review registrationPROSPERO CRD42022308978.
