Predictive models are increasingly crucial in navigating heterogeneous markets. This study develops a predictive model approach to forecast consumer cluster membership in the green fast-moving consumer goods sector, focusing on bio-based products like adhesives and plasters. Through two online surveys in Germany, we identified key factors acting as drivers and barriers, demonstrating their effectiveness in distinguishing similar consumer segments across both product categories. Utilizing multinomial logistic regression, we crafted a prediction model that accurately forecasts cluster membership, providing novel insights into consumer behavior towards non-food bio-based products. This facilitates the development of targeted business and marketing strategies, optimizing resource allocation in market research activities. Our findings offer significant contributions to understanding the dynamics influencing consumer choices in the bio-based product market.

Natural cosmetics offer the opportunity to reduce the environmental burden caused by the consumption of cosmetic products. This qualitative study analyzes the local range of natural cosmetics and related consumer perceptions and assessments in two case cities in Germany by applying a mixed-method approach of store checks and the photovoice method. Results of the study show that there is only a limited match of the actual range and consumer perception for some types of retail businesses and a mismatch for product categories. Additionally, participants showed little awareness of the most common natural cosmetic certifications. Consumer assessments about the range of natural cosmetics were influenced by factors such as the arrangement of products in the shops and consumers' experience and knowledge about natural cosmetic brands. Retailers can use the study results in arranging natural cosmetics accordingly; companies can use it to emphasize branding, and policy-makers can increase consumer knowledge about natural cosmetics.

BackgroundNatural health products (NHP) are an important part of the healthcare system. They are mainly non-prescription and sold over the counter, which requires active decision making by the consumer. Within the framework of the Complementary and Alternative Healthcare Model, this study aims to identify factors that influence NHP usage, in particular related to concentration and cognition (CC), a topic that concerns all ages and social classes within the population.MethodsData were collected by means of a representative online survey (n = 1,707) in Germany in April 2022. Three user groups were defined: NHPCC users, who used NHP for CC (12 month prevalence); nCC-NHP users, who used NHP but not for CC indications (12 month prevalence); and past NHP users, who have used NHP but not within the previous 12 months. Independent influencing variables were categorized into predisposing, enabling, need, and health service use factors. Data were analyzed with descriptive statistics, inferential statistics, and binary logistic regression models to compare NHPCC users to nCC-NHP users (model 1) and to past NHP users (model 2).ResultsA higher share of NHPCC and nCC-NHP users compared to past NHP users were women, self-medicated with NHP, and used information about NHP provided by health professionals or on product. Their openness-to-change value orientation was more pronounced than of past users. Compared to nCC-NHP and past NHP users, the probability of being an NHPCC user increased if an individual had more difficulties in daily attention and memory performance, made use of health professionals and literature to seek information about NHP, and used NHP for health support and illness prevention. Additionally, a female gender, NHP self-medication, and having higher values of self-transcendence were significant indicators for NHPCC usage compared to past NHP usage.ConclusionNHP manufacturers, health professionals, and policymakers should be aware of the factors that lead to NHP consumption decisions and consider them in the development and optimization of healthcare strategies as well as in the marketing and communication strategies of companies producing NHP, in particular for CC. The current study can contribute to characterizing the target groups and to defining the aims and communication channels of such campaigns.

Using bio-based building products for renovation and refurbishment contributes to a bioeconomy. As private consumers mainly buy building products at local hardware stores, it is essential to consider the local supply situation. This qualitative study analyzes the local range of bio-based building products for renovation and refurbishment and related consumer perceptions and assessments in two case cities in Germany. The study results reveal that consumers face high search costs, the range of products is primarily narrow, and their placement and presentation are unfavorable. Manufacturers can use the study results and invest in classical marketing strategies, and initiate pull strategies with consumers for bio-based building products. This could motivate retailers to increase the range and improve the placement and presentation of such products. Finally, policymakers can apply the insights from this study to educational campaigns and the promotion of quality labels in this field.

BackgroundRespiratory diseases (RD) can challenge healthcare systems around the globe. Natural health products (NHPs) are popular complementary and alternative medicine options for health issues concerning non-fatal RD. Little is known about the characteristics of the users of RD-NHPs and about their NHP consumption behavior during the Covid-19 pandemic in Germany.MethodsA representative online survey was conducted in Germany in 2022. 1707 participants were classified based on having used NHPs for RD within the previous 12 months, having used NHPs but not for RD within the previous 12 months and not having used NHPs. Data were analyzed using descriptive and inferential statistical methods as well as a multinomial logistic regression model.ResultsUsers of RD-NHPs within the previous 12 months were more likely to be employed and to consult pharmacists more often for non-fatal health issues than individuals who did not take RD-NHPs. RD-NHP users were more likely to suffer from a Covid-19 infection and to have children living in the same household than other NHP users. Compared to non-NHP users, RD-NHP users were more likely to be female, highly educated and have stronger openness-to-change value orientations. Vaccination-related behavior was no indicator of RD-NHP usage. Most RD-NHP users took NHPs in self-medication. Few reported informing their practitioner about their self-medication. Drugstores were the most visited supply source for NHPs during the pandemic, followed by pharmacies. Common information sources regarding NHPs were the products themselves and pharmacists.ConclusionThis study emphasized the important role of NHPs as a popular prevention and treatment option for RD. RD-NHPs were more likely used by individuals who were employed, who suffered from a RD and who consult pharmacists for non-fatal health issues. The importance of product information and pharmacies as information sources should be considered to make communication strategies about safe self-medication options with RD-NHPs more effective, which could help to reduce the burden of health facilities regarding non-fatal RD. To improve and develop future pandemic-control strategies, health professionals and policy makers should consider NHP usage behavior and provide critical information about chances and risks of self-medicated NHP consumption.

A strong link between emotions and eating behavior has been previously found, however there is a lack of research investigating how emotions influence food product choice in a retail setting. An online questionnaire including a choice-based conjoint analysis and self-reported consumer emotions was used to assess the importance of different product attributes to yogurt consumers in Germany in 2021. The analysis consisted of a Hierarchical Bayes approach and a cluster analysis. The results revealed that yogurt consumers placed most importance on ingredients, followed by price, Nutri-Score, flavour, and finally production method. Based on the self-reported consumer emotions, a positive, a rather positive and an indifferent emotion cluster was found. The positive cluster preferred the highest quality in terms of ecological and health values and was willing to pay more for such a yogurt. The rather positive cluster preferred these options as well, however was not always willing to pay more for them. The indifferent cluster was more driven by lower prices and was more willing to trade other qualities for the cheapest option. These findings are insightful for food marketing and health interventions as shopping experience, as well as product choice could be enhanced through emotion induction.

Bio-based products represent a promising alternative to fossil-based products and contribute to reduce negative environmental consequences caused by the latter. As consumer behavior is crucial for market penetration of bio-based products, this review analyses the current state of the art in consumer research on bio-based products and aims to identify research gaps and future research needs. This review is based on a systematic synthesis of 59 scientific journal articles and one book chapter on consumer studies related to bio-based products. Peer-reviewed studies in English language, with a research focus on consumer issues related to bio-based products of plant origin, that aim to replace fossil resources, have been included in the review. Most reviewed studies investigated bio-based plastics and composites, used a quantitative research approach, have been based on established consumer theories and used non-probability sampling techniques. While consumer preferences and attitudes, conviction as well as knowledge and perception related to bio-based products were focus of many reviewed studies, consumer awareness, liking and purchasing of bio-based products have been studied rarely or not at all. The results show that many consumers are not aware of the existence of bio-based products, related knowledge is low, and labels and brands are often unknown. Additionally, some consumers have wrong assumptions about the environmental impact of bio-based materials. Consumer preferences vary between product groups, but often factors like price or functionality are more important than bio-based materials. High purchase intentions and an increased willingness to pay are found e.g. for bio-based packaging products, disposable products and plant containers (in particular for female and environmentally-concerned consumers). The review identifies important research gaps and conclusions for future research needs such as e.g., to realize more studies in countries of the global south, analyze actual purchase behavior and the regional supply situation related to bio-based products.

Im Projekt wurde eine Studie an 39 Senioren in 2 Pflegeeinrichtungen durchgeführt. Ziel war es, Anreicherungstechniken für eine komplette Nährstoffanreicherung zu entwickeln, in verschiedenen Pflegeeinrichtungen durchzuführen, sowie die Entwicklung von neuen kostengünstigen Proteinformulierungen. Die Pflegekräfte können damit, dem Probanden die gewünschte Menge Proteinsahne geben und stellen so die Nährstoffaufnahme sicher. Zudem konnten bei der Studie Mahlzeiten für Bewohner mit Kau- und Schluckbeschwerden verbessert werden. Diese Personen bekamen vor der klinischen Studie täglich püriertes Essen. Um den optischen Eindruck zu verbessern, wurde dies in der Studie mit einem Texturierungsmittel versetzt und mit Silikonformen wieder in die originale 3D Form gebracht. Vor dem Servieren wurden die Lebensmittel aus den Formen gelöst, auf den Teller gegeben und erwärmt. Das Pflegepersonal bestätigt, dass die Bewohner ihr Essen wieder besser erkennen konnten und eine deutlich höhere Begeisterung für die Mahlzeiten haben. Ziel des 2. Projektteils war es, die Wirksamkeit personalisierter Preispromotionen für gesunde Lebensmittel in Supermärkte zu testen, um Konsumenten zu einer gesünderen Lebensmittelwahl zu bewegen. Hierzu wurden auf Basis von Verbraucherpaneldaten verhaltensbezogene Verbrauchersegmentierungen für verschiedene Warengruppen durchgeführt. Zur Bestimmung der Einflüsse von maßgeschneiderten Aktionen auf den Kauf von fettarmen Produkten wurden ein Modell und eine simulationsbasierte Methode entwickelt. Der Ansatz basiert auf einem gemeinsamen Modell aus Kaufereignis, Wahlentscheidung und Kaufmenge und wurde für verschiedene Ebenen umgesetzt. Zudem wurden die Absatzahlen verschiedener Filialen eines Lebensmittelhändlers für definierte Warengruppen vor und nach einer Preisreduktion untersucht. Die Ergebnisse einer Online-Studie zeigen, dass bei der Entscheidung für Joghurt die Inhaltsstoffe die wichtigsten Entscheidungskriterien für Probanden darstellen.

Public acceptance of agricultural technologies is an important determinant of their success. In the case of autonomous crop robots, recent research from Germany suggests that societal acceptance of the technology plays an important role for farmer acceptance of crop robots. Yet little research has been conducted so far into how the public perceives autonomous agricultural technologies like crop robots. Investigating the public’s opinion on crop robots will provide answers to one of farmers’ questions in the decision to invest in crop robots. Through consumer segmentation and hypotheses-based characterization, specific consumer groups with differing attitudes towards crop robots are identified. Two discrete choice experiments on digital and autonomous methods of weed management (n = 675) and tractor size and degree of autonomy (n = 645), conducted as part of a larger representative consumer survey in Germany (n = 2,012), are submitted to a Hierarchical Bayes estimation and subsequent latent class analysis. The identified consumer segments are characterized in a hypotheses-based approach with hypotheses centering on consumer attitudes measured as 5-point Likert-type items and as spontaneous image associations. Both subsamples can be segmented into three groups, which are comparable between the experiments in their socio-economic composition. Results suggest that the German public is largely positively inclined towards autonomous agricultural technologies. The method of weed control is considered more important than the vehicle type (i.e., conventional tractor or crop robot) and vehicle size is considered more important than degree of autonomy. Only the respective smallest consumer segments in the two experiments indicate indifference or a more conservative perspective. Participants’ attitude towards environmental preservation appears to have a positive influence on their evaluation of autonomous agricultural technologies. To the authors’ best knowledge, this is the first investigation into the public opinion of crop robots, based on a large sample representative of the German population in four socio-demographic variables. It indicates that the German population is most interested in the reduction of agrochemicals in plant production and will also accept autonomous agricultural technologies to achieve this goal. Policymakers should make use of these insights when communicating about novel technologies in agriculture and extension agents should relay this information to farmers, particularly those already interested in investing in crop robots.
