This research aims to gain insight into how consumers interact with a commercially available genetic nutrition programme, DNAfit, to explore health change via an intervention.

Focus groups were conducted between June and October 2019, pre-, during- and post-intervention, with a total sample of 14 younger (aged 25–44 years) and 14 mature (aged 45–65 years) cohorts from New Zealand. Qualitative thematic analysis was completed with the help of NVivo software.

Younger participants in this study engaged less overall with DNAfit, felt the service did not match their lifestyles and did not encourage their believability of genetic personalised nutrition (GPN). In contrast, mature participants had positive engagement with GPN, as their motivation to use the service fit with their motivation for longevity. Overall, social uptake in health changes based on GPN is likely to depend on life stage.

This paper adds to limited social marketing research, which seeks novel avenues to explore how consumers engage with GPN technologies to drive social change, assisting social marketers on how to more effectively deliver health programmes that allow consumer-driven interaction to build health capabilities.

The purpose of this paper is to explore how spirituality impacts on the consumption choices of consumers who are adopting a sustainable lifestyle.

This is a longitudinal study of urban-based consumers who are actively engaged in living sustainably. To effectively study these lifestyles, a multi-modal research design was used, which combined photo-elicitation, journaling, interviews and observational data.

Spirituality and material consumption are traditionally depicted as being in opposition, with research finding a decrease in conspicuous consumption when spirituality is enhanced. This research demonstrates sustainability-mindful consumers who are reversing this trend by enacting their deeply held ideological beliefs through their consumption choices. The merging of ideology with consumption elevates even mundane purchases to be acts of meaning and purpose.

With an unwillingness to compromise on their beliefs, there is a growing gap between these consumers’ demands and what the market is offering. The study found evidence of these consumers developing their own consumables in direct response to a lack of appropriate market alternatives.

This study demonstrates consumers for whom spirituality is at the centre of their consumption choices. Further, it provides evidence that supports Maslow’s theory of being motives (self-actualization and self-transcendence), in which people are motivated by the desire to fulfil their highest life potential. This research suggests opportunities for those businesses that are willing to meet consumers’ transcendent needs through more transparent and socially responsible practices.

This paper proposed an adaptation of the theory of planned behavior (TPB) model to study the factors influencing organic food purchase behavior in an emerging market. This research introduced household norms as an important factor that reflected the influence of household activities and family pressure on individuals to perform organic food purchase behaviors. The role of trust in organic food as a direct and a moderating factor was examined in the proposed framework as well.

The study proposed a model with 10 hypotheses from the literature review. The hypotheses were tested using data collected from 407 organic food customers in Hanoi, Vietnam. The partial least squares structural equation modeling (PLS-SEM) approach was used for analysis.

The results indicated that household norms played an important role influencing purchase intention and behavior. This research also showed that trust in organic food directly affected purchase intention and played a moderating role on the attitude towards organic food and purchase intention relationship. However, trust in organic food did not show moderating effects on other relationships in the model.

More context-specific reasons may be incorporated into the research model to better explain consumer purchase behaviors.

The role of household norms and its impact under TPB has not been investigated for organic food purchase behaviors, particularly in emerging markets.
