This review evaluates the methodological quality of current front-of-pack labeling research and discusses future research challenges. Peer-reviewed articles were identified using a computerized search of the databases PubMed andWeb of Science (ISI) from1990 to February 2011; reference lists fromkey published articleswere used as well. The quality of the 31 included studies was assessed. The results showed that the methodological quality of published front-of-pack labeling research is generally low to mediocre; objective observational data-based consumer studies were of higher quality than consumer studies relying on self-reports. Experimental studies that included a control group were lacking. The review further revealed a lack of a validated methodology to measure the use of front-of-pack labels and the effects of these labels in real-life settings. In conclusion, few methodologically sound front-of-pack labeling studies are presently available. The highest methodological quality and the greatest public health relevance are achieved by measuring the health effects of front-of-pack labels using biomarkers in a longitudinal, randomized, controlled design in a real-life setting.

Positive health (PH) has been described as a promising transformative innovation to address the challenges of promoting well-being and reducing the burden of disease. For this study, we conducted a scientific literature review of the current state of knowledge about PH as introduced by Huber and colleagues, following the Cochrane Rapid Review recommendations. Three databases were searched (PubMed, Google Scholar, and CINAHL). Data were extracted and synthesised using a narrative approach. A total of 55 articles were included. The initial evaluation revealed promising results at both the individual and collective levels. However, several articles gave reason for further refinement of the conceptualisation of PH and of ways to measure the effects of PH interventions in greater detail. Professionals also expressed a desire for a more informed application and elaboration of the PH method, in various settings and populations, to increase its effectiveness in practice. The results from the rapid review highlight the transformative potential of PH in shifting from a disease-oriented to a health-oriented paradigm of healthcare. This underlines the need for continued research regarding further development of the concept and its practical method, along with the necessity for methodological innovation.

Understanding the complex and dynamic nature of experiences requires the use of proper measurement tools. As interest grows in the objective measurement of experiences within tourism and hospitality, there is an urgent need to consolidate and synthesize these studies. Thus, this study investigated prevalent objective measurement techniques via a systematic review. We analyzed physiological measures such as electroencephalography (EEG), heart rate variability (HRV), skin conductance (SC), and facial electromyography (fEMG) along with behavioral measures, including eye tracking and location tracking. This review identified 100 empirical studies that employed objective measurement to examine tourism and hospitality experiences over the last decade, highlighting trends, research contexts and designs, and the synergies between different methods. Our discussion on methodological issues and best practices will help researchers and practitioners identify the best tools to capture people’s experiences and promote more standardized practices and comparable findings on studying experiences in tourism and hospitality settings.
