The Dutch Eating Behavior Questionnaire is an internationally widely used instrument assessing different eating styles that may contribute to weight gain and overweight: emotional eating, external eating, and restraint. This study aimed to evaluate the psychometric properties of the 30-item German version of the DEBQ including its measurement invariance across gender, age, and BMI-status in a representative German population sample. Furthermore, we examined the distribution of eating styles in the general population and provide population-based norms for DEBQ scales. A representative sample of the German general population (N = 2513, age > 14 years) was assessed with the German version of the DEBQ along with information on sociodemographic characteristics and body weight and height. The German version of the DEQB demonstrates good item characteristics and reliability (restraint: α = .92, emotional eating: α = .94, external eating: α = .89). The 3-factor structure of the DEBQ could be replicated in exploratory and confirmatory factor analyses and results of multi-group confirmatory factor analyses supported its metric and scalar measurement invariance across gender, age, and BMI-status. External eating was the most prevalent eating style in the German general population. Women scored higher on emotional and restrained eating scales than men, and overweight individuals scored higher in all three eating styles compared to normal weight individuals. Small differences across age were found for external eating. Norms were provided according to gender, age, and BMI-status. Our findings suggest that the German version of the DEBQ has good reliability and construct validity, and is suitable to reliably measure eating styles across age, gender, and BMI-status. Furthermore, the results demonstrate a considerable variation of eating styles across gender and BMI-status.

The World Health Organisation ([WHO], 2007) declared obesity as the public health threat of the 21st century. Currently, the Maltese adult population ranks as the heaviest in the Euro‐Mediterranean region. In response to a gap in Maltese research on the area of obesity and food consumption, this PhD aimed to gather local data to unearth behavioural‐psychological factors that could be implemented in local interventions. The focus of the PhD was narrowed to women with families based on literature that has identified motherhood as a salient point of transition that amplifies the weight trajectories for adult women. A mixed‐methods approach guided the methodology of the PhD programme with four studies carried out sequentially in two phases. The findings of the qualitative phase revealed that weight management for Maltese mothers was enmeshed with gender norm expectations surrounding motherhood. For mothers with a higher BMI, their relationship to food was a significant barrier to weight loss maintenance. Mothers with a lower BMI or who maintained their weight pointed at their food planning ability to manage their diet. The quantitative phase extended literature on the dimensional validity of the Dutch Eating Behaviour Questionnaire (DEBQ) (Van Strien et al., 1986) by reproducing its factor structure and ascertaining its reliability among Maltese women. This was the first validation of an eating behaviours assessment tool in Maltese and the first validation of the DEBQ in a Semitic language. Finally, Structured Equation Modelling revealed how food planning could act as a mediator to restrained and external eating styles to increase fruit and vegetable snacking and decrease high calorie snacking. In addition to the implications to theory, it is believed that these findings have worthy practical implications through tailored eating behaviour interventions, by targeting food planning to counterbalance the impact of external eating among Maltese mothers.

This work examines and presents evidence for the existence of a gap in epistemological views between academic and practice marketers. Few if any academics would seem to challenge the ‘gap’ premise but the importance of any gap and its nature are issues about which little agreement exists. The intractable nature of the academic practitioner gap has a long history of interesting and diverse debate ranging from Dewey’s argument about the true nature of knowing to contributions based on epistemic adolescence, ontological differences and more pragmatic suggestions about different tribes. Others include the rigour versus relevance issue, failures in curriculum or pedagogy and a clash between modernist and postmodernist epistemologies. Polanyi’s description of tacit versus explicit knowledge further extends the debate as do issues of knowledge creation and dissemination in particular through Nonaka. Irrespective of approach actual evidence for a gap was largely based on argument rather than empirical proof. This work address that lack. The intractability of the gap suggests that it is at root, epistemic. To identity the existence of a gap in such terms a domain specific epistemic questionnaire developed by Hofer was used. A factor analytic process extracted a common set of factors for the domain of marketers. Five epistemic factors were identified. Three of these showed significant difference in orientation between practitioners and academics confirming that the theory practice gap is tangible and revealing an indication of its nature Broadly results from factor analysis with interpretation informed by factor item structure and prior theoretical debate suggests that academics and practitioners views on knowledge and how they come to know share similarities and differences. Academics are more likely to see knowledge as stable, based on established academic premise legitimized from academy. Practitioners are more likely to see knowledge as emerging from action, as dynamic and legitimised by results. Other significant findings included the emergence of dialogue as a means of closing the gap, and the emergence of a group of academics with significant practice experience termed here as, hybrids, who are located in the Academy but mostly share their epistemic views with practitioners. Correlation analysis showed that academic propensity to engage in dialogue with practice moved academic factor scores towards practitioners. This shows that dialogue has a clear role in both perpetuating the gap in its absence or reducing it. Fundamentally dialogue plays a clear role in bridging the two epistemologies and in providing for additional epistemic work. Finally a solution to bridging the gap has been proposed. The model called dialogic introspection melds dialogue and introspection to create epistemic doubt, the volition to change and a means of resolution. The model avoids prescription of what form knowledge should take but instead adopts a stance similar to more mature disciplines like medicine in which the status of academic work is enhanced in line with its relevance to practice which itself is embodied in dialogue. This approach recognizes the centrality of epistemology as shaping the conditions necessary for recognizing epistemologies as hierarchies in which the epistemology most capable of additional epistemic work is the most desirable. Such an epistemology would have the capacity to add epistemic work and reinforces Nonaka’s call for epistemology to be recognized as central to knowledge creation.
