- PublikationReducing individual meat consumption: The role of socio-psychological factors and the stage model of behavioral change(2019) Weibel, Christian; Kossmann, Katharina; Schaffner, Dorothea; Ohnmacht, Timo [in: Journal of Food Quality and Preference]The aim of this study is to identify the factors involved in reducing meat consumption. Meat consumption is a major contributor to greenhouse gas (GHG) emissions and thus to climate change. Since meat consumption is a voluntary form of behavior, and since only 1.4 percent of the Swiss population are strict vegetarians, there is considerable potential for behavioral change. We propose an integrated and dynamic model based on a theory of planned behavior and a phase model of behavioral change to identify the factors involved in encouraging behavioral change and to discuss their practical implications. Our findings, based on a representative survey applying a multi-nominal logit approach, suggest that it is mainly attitude, perceived behavioral control, personal norms and problem-awareness that have significant impacts on the phase an individual has reached in a process of behavioral change (pre-decision, pre-action, action and post-action). The theoretical, empirical and practical implications discussed here will increase our understanding of the effectiveness of interventions aimed at reducing meat consumption. This should aid public authorities, policy-makers and marketing professionals in deciding how to promote a meat-reduced diet by choosing the most promising factors for behavioral change.01 - Zeitschriftenartikel, Journalartikel oder Magazin

- PublikationHow to postpone purchases of a new mobile phone? Pointers for interventions based on socio-psychological factors and a phase model of behavioural change(Elsevier, 2018) Ohnmacht, Timo; Thi Vu, Thao; Schaffner, Dorothea; Weibel, Christian [in: Journal of Cleaner Production]Due to the short life-spans of mobile phones, materials are wasted and the degradation of the environment from mineral mining increases. We examine the relationship between the socio-psychological factors that affect the status in four phases of a model of behavioural change (predecision, preaction, action, postaction) with regard to postponed purchases of a new mobile phone by using an ordered logit approach. Representative data from 1818 residents of the city of Lucerne, Switzerland, were collected. The empirical results indicate that the significant effects of socio-psychological factors on phase affiliation provide an orientation framework for the design of interventions. There is evidence that influencing perceived behavioural control to increase affiliation to higher phases by inter alia longer battery life spans, fewer updates that slow down the system, and extended options for repair and maintenance to extend the longevity of the mobile phone.01A - Beitrag in wissenschaftlicher Zeitschrift
