    How to eat healthy and save the planet. Development and evaluation of an evidence-based app
    (2019) Feck, Vanessa; Herrmann, Anne; Visschers, Vivianne
    Background: Food consumption affects individuals as well as our planet. How can a tailored app help people to make healthier and more sustainable meal choices? To answer this question, we contributed to the development of an evidence-based dietary app and evaluated its effects. The app offers personalized recipes and tips in order to reduce food waste and meat consumption, and increase the use of seasonal and plant-based products. Method: Using a mixed-methods approach, app usage data (N=2167) and quantitative data from a longitudinal online questionnaire (T1-T3: N=56) were combined with in-depth interviews with users (N=6) and app-developers (N=3). Findings: In the interviews, users evaluated the personalized recipe-suggestions positively. An additional search (e.g. recipes with certain ingredients) was often no longer necessary to find a suitable recipe. The app metrics showed positive correlations between frequent app usage and the motivation to reduce food waste (r=.06, p<.05) as well as the motivation to use seasonal products (r=.16, p<.01). The survey data showed that participants’ initial confidence to implement new dietary behavior was a strong predictor of the implementation of new dietary behavior after three weeks of app usage (β≥.49, p≤.01, R2 = .66). Last, the development team emphasized the benefits of an iterative approach in which regular user feedback informed the further development process of the app. Discussion: The results of this research show that it can be effective to combine health- and sustainability-focused diet interventions. These interventions should be personalized and aim to increase users’ confidence to perform new dietary behavior.

    The protean career orientation as predictor of career outcomes: evaluation of incremental validity and mediation effects
    (Elsevier, 18.06.2015) Herrmann, Anne; Hirschi, Andreas; Baruch, Yehuda [in: Journal of Vocational Behavior]
    A protean career orientation is assumed to be beneficial for career development but researchers have only recently started to empirically evaluate the concept. Conducting two studies based on three independent samples of university students and working professionals in Germany, we address issues of concurrent validity, predictive incremental validity and mechanisms linking the protean orientation to career outcomes. The first study showed that in a sample of 104 German employees different measures of the protean career orientation all correlated highly, but not identically, to a range of work and career attitudes. Using bootstrapping analysis, a second study with a six-month prospective examination among 419 German university students and a cross-sectional analysis among 526 German employees showed that a protean career orientation predicts proactive career behaviors and career satisfaction beyond a proactive disposition and core self-evaluations, respectively. Moreover, the protean career orientation was a significant mediator of these two personality constructs on both career outcomes. Cumulatively, the studies enrich our understanding of how and when a protean career orientation is related to important career outcomes.

    Career adaptivity, adaptability, and adapting: a conceptual and empirical investigation
    (Elsevier, 04/2015) Herrmann, Anne; Hirschi, Andreas; Keller, Anita [in: Journal of Vocational Behavior]
    The literature on career adaptation is vast and based on a range of different measurement approaches. The present paper aims to explore how different operationalizations of career adaptability in terms of concern, control, curiosity, and confidence are related from a conceptual and empirical standpoint. Based on a cross-sectional analysis with 1260 German university students, we established that the adaptability resources of concern, control, curiosity, and confidence are significantly related to, but empirically distinct from, measures representing adapting in terms of career planning, career decision-making difficulties, career exploration, and occupational selfefficacy. In a follow-up survey six months later, we found that the career adaptability dimensions partially mediated the effects of adaptivity (i.e., core self-evaluations and proactivity) on planning, decision-making difficulties, exploration, and self-efficacy. Interestingly, in both analyses, there was no clear match between adaptability resources and theoretically corresponding aspects of career adapting in terms of behaviors, beliefs, and barriers. The results suggest that psychological career resources in terms of concern, control, curiosity, and confidence partially mediate the effects of more context-general, trait-like adaptivity on different career-specific behavioral forms of adapting.

    The career engagement scale: development and validation of a measure of proactive career behaviors
    (SAGE, 2014) Hirschi, Andreas; Freund, Philipp Alexander; Herrmann, Anne [in: Journal of Career Assessment]
    Careers today increasingly require engagement in proactive career behaviors; however, there is a lack of validated measures assessing the general degree to which somebody is engaged in such career behaviors.Wedescribe the results of six studies with six independent samples ofGerman university students (total N ¼ 2,854), working professionals (total N ¼ 561), and university graduates (N ¼ 141) that report the development and validation of the Career Engagement scale—a measure of the degree towhich somebody is proactively developing his or her career as expressed by diverse career behaviors. The studies provide support for measurement invariance across gender and time. In support of convergent and discriminant validity, we find that career engagement is more prevalent among working professionals than among university students and that this scale has incremental validity above several specific career behaviors regarding its relation to vocational identity clarity and career self-efficacy beliefs among students and to job and career satisfaction among employees. In support of incremental predictive validity, beyond the effects of several more specific career behaviors, career engagement while at university predicts higher job and career satisfaction several months later after beginning work.

    Simple measures and complex structures: Is it worth employing a more complex model of personality in Big Five inventories?
    (Elsevier, 18.05.2013) Herrmann, Anne; Pfister, Hans-Rüdiger [in: Journal of Research in Personality]
    The poor performance of five-factor personality inventories in confirmatory factor analyses (CFAs) prompted some to question their construct validity. Others doubted the CFA’s suitability and suggested applying Exploratory Structural Equation Modeling (ESEM). The question arises as to what impact the application of either method has on the construct validity of personality inventories. We addressed this question by applying ESEM and CFA to construct better-fitting, though more complex models based on data from two questionnaires (NEO PI-R and 16PF). Generally, scores derived from either method did not differ substantially. When applying ESEM, convergent validity declined but discriminant validity improved. When applying CFA, convergent and discriminant validity decreased. We conclude that using current personality questionnaires that utilize a simple structure is appropriate.

    Calling and career preparation: investigating developmental patterns and temporal precedence
    (Elsevier, 13.03.2013) Hirschi, Andreas; Herrmann, Anne [in: Journal of Vocational Behavior]
    The presence of a calling and career development are assumed to be closely related. However, the nature of and reason for this relationship have not been thoroughly investigated. We hypothesized the existence of reciprocal effects between calling and three dimensions of career preparation and assessed the change of the presence of a calling, career planning, decidedness, and self-efficacy with three waves of a diverse sample of German university students (N = 846) over one year. Latent growth analyses revealed that the intercepts of calling showed a significant positive correlation with the intercepts of all career preparation measures. The slope of calling was positively related to those of decidedness and self-efficacy but not to planning. Cross-lagged analyses showed that calling predicted a subsequent increase in planning and self-efficacy. Planning and decidedness predicted an increase in the presence of a calling. The results suggest that calling and career preparation are related due to mutual effects but that effects differ for different career preparation dimensions.

    Assessing difficulties in career decision making among Swiss adolescents with the German My Vocational Situation Scale
    (Hogrefe, 2013) Hirschi, Andreas; Herrmann, Anne [in: Swiss Journal of Psychology]
    Assessing problems in career decision making among adolescents is important for career guidance and research. The present study is the first to investigate among Swiss adolescents the factor structure and convergent validity in relation to personality of the German-language adaptation of the My Vocational Situation Scale. Two preliminary studies (N = 217) suggested that using a 5-point Likert scale response format would increase scale reliability. The confirmatory factor analyses in the main study with two cohorts (n = 341, eighth grade; n = 303, eleventh grade) confirmed that four main factors, which assess problems with identity, decision making, information, and perceived barriers, underlie the data. The barriers factor was differentiated into aspired vocation and personal situation. Construct validity was supported by significant relationships between favorable personality characteristics (emotional stability, extraversion, agreeableness, conscientiousness, generalized self-efficacy, and internal locus of control) and fewer problems. The results suggest that the vocational identity and barriers scales can be fruitfully applied to research on and the practice of career counseling with adolescents.

    Vocational identity achievement as a mediator of presence of calling and life satisfaction
    (SAGE, 2012) Hirschi, Andreas; Herrmann, Anne [in: Journal of Career Assessment]
    The present study explores what mechanism might be responsible for the reported link between presence of a calling in one’s career and life satisfaction. It is proposed that vocational identity achievement acts as one important mediator of this relation and that the effects can be observed even when controlling for core self-evaluations (CSEs). The study used a short-term longitudinal design based on a sample of 269 German college students from different majors. The results confirmed the mediation model, with calling predicting vocational identity achievement 6 months later and identity serving as a stronger predictor of life satisfaction, all controlling for CSEs. However, contrary to previous research, presence of calling was not directly related to life satisfaction and even showed a negative relation when vocational identity achievement was controlled. The results are interpreted to suggest a multifaceted relation between calling and life satisfaction.
