Die Integration qualitativer und quantitativer Forschung – theoretische Grundlagen von „Mixed Methods“

Mixed Methods have been used in social research for quite a long time, as can be seen by looking on influential empirical studies from the first half of the 20^th century, where the combined use of qualitative and quantitative methods was justified in most cases only pragmatically (if at all). Unfortunately, the discussions led from the 1970s onwards about theoretical justifications of mixed methods designs often suffered from a focus limited on formal and epistemological issues. This holds true for the debates about the notion of “triangulation” as well as for the controversies about the paradigms presumably underlying quantitative, qualitative or mixed methods research. By contrasting “positivism”, “constructivism” and “pragmatism” outdated frontlines were often preserved and complex philosophical problems oversimplified. Furthermore, the focus on epistemology led to a neglect of substantial issues relating to the research field (which are always critical for the use of methods).The necessity for using (and combining) quantitative and qualitative methods follows from the nature of social structures relevant for the concrete field of investigation which may differ widely according to their stability and flexibility. Thereby structures with limited scope or “contingent structures” create specific problems for qualitative and quantitative methods which can be detected and dealt with by drawing on the strengths of the respective other methodological tradition in mixed methods designs.     

Datenanalyse in der Mixed-Methods-Forschung

This article discusses data analysis in mixed methods approaches. The challenge of integration during the stage of analysis has recently become a main point of the discourse on mixed methods that for more than a decade had been centered on topics of research design and compatibility of paradigms. The article focuses on key aspects of integration strategies as well as on points of the integration, which depend largely on the research design of the project. Ten different integration strategies in three areas are presented in detail, namely result-based, data-based and sequence-oriented integration strategies. Joint displays, which jointly present data and/or results of the qualitative and the quantitative research strands a particularly important.     

Developing a culturally-specific mixed methods approach to global research

With much of the development of mixed methods occurring through the works of scholars from the US, the UK, Canada, and the Anglos-Saxon/English-speaking countries, the discourse about a global research community must consider how it needs to be sensitive to diverse cultures. Clearly, the discussion must focus on adapting mixed methods to best fit the problems of countries, the cultural norms of conducting research, and the scholarly talents of in-country investigators. Unfortunately, the mixed methods literature is largely silent on diverse cultural adaptations of mixed methods.In this article, we first trace the involvement of worldwide countries in the historic development of mixed methods. Then, to gain a better understanding of the use and adaptation of mixed methods in diverse world academic cultures, we provide a qualitative study of themes mentioned by participants from seven different countries. From both the historical overview and the qualitative study, we end by making suggestions about specific strategies for a global discourse about mixed methods research, and suggest a de-colonizing presence of the Anglo-Saxon/English-speaking countries in the global expansion of mixed methods.     

Evidenztriangulation in der Gesundheitsforschung

The contribution starts with weaknesses of a strict quantitative methodology in social research. Especially in health research variable connections are so complex that a broader understanding of research methods seems to be necessary. The dominance of quantitative-experimental ongoing in the sense of randomized controlled trials (RCT) at the top of the evidence hierarchy is criticized and a concept of evidence triangulation in the sense of mixed methods is proposed as alternative. An example study shows the logic of this research design. An institution of drug addicts counseling and therapy is analyzed in its effects through an evaluation study, using four different methodological approaches, an experimental pre-post design, qualitative interviews with the clients, and qualitative and document analysis using qualitative content analysis are combined. Each of them is developed in criticizing and supplementing the other approaches. The mixed methods procedure therefor follows a dialectical theory of science.     

Sequentielles Mixed-Methods-Sampling: Wie quantitative Sekundärdaten qualitative Stichprobenpläne und theoretisches Sampling unterstützen können

Mixed methods sampling has played a minor role in methodological discussions so far. In particular, there is a lack of information about practical implementations and critical reflections of sampling decisions and sampling steps showing the benefits and challenges of different approaches. Therefore, this paper demonstrates by drawing on an empirical example, how quantitative secondary data analysis (German Socio-Economic Panel, Linked Employer-Employee Data, Employment History) can support the empirically informed formation of contrast groups for qualitative sampling plans as well as field access to these contrast groups. Furthermore, the article will show how an additional theoretical sampling can extend the empirically grounded composition of contrast groups and can build upon the quantitative secondary data. The discussion is based on a project with an explanatory sequential research design which combines quantitative secondary analysis with subsequent expert interviews with human resources managers in companies and narrative interviews with employees. The project focusses on the causes, practices, and consequences of employment relationships with an interrupted membership in the same employing organization (“recalls”).     

Ausgrenzung,Klassenzusammenhalt, Kooperation und Selbstbehauptung. Eine quasi-experimentelle Untersuchung der personal-sozialen Kompetenzen bei Schüler/-innen mit einer erlebnispädagogischen Intervention

With a classic quasi-experimental design (two measuring points, treatment and control group) the two questionnaires have been raised in the 2nd/3rd school week and after the first quarter with the constructs “class cohesion” and “exclusion” and “cooperation” and “self-assertion”. The treatment took place in the fourth week of beginning secundary classes (Switzerland). After the treatment the students showed significantly less exclusion ambitions and a better class cohesion than the control group. This finding should take into account the disturbing variables which must be meaningfully interpreted. And with respect to the sample the treatment group was – compared to the German standard – either socially more competent or biased.     

Kulturwandel im Geldgeschäft? Potenziale einer ethischen Selbsterneuerung im Banken- und Finanzwesen

Following the financial crisis in 2008 a debate about the social benefit of the financial industry, which operates without considering its real-economic consequences, was initiated. The financial industry responded by offering strategies of cultural change (“Kulturwandel”) which foster a more socially responsible financial practice. At the same time the expansion of “ethical” banks aims to establish a banking business avoiding negative externalities of the banking sector. Following the conceptual assumptions of the sociology of critique we study the collectively shared interpretation of a “good” and legitimate financial practice beyond publicly communicated standards of practice. Against this backdrop we evaluate the potentials of normative self-regulation in banking and finance. Our results show that cultural or ethical change is only partly feasible if it exclusively focuses the motives, values and personalities of the individual subjects but neglects the structural as well as institutional conditions of a “good” financial practice.     

Understanding the philosophical positions of classical and neopragmatists for mixed methods research

Pragmatism is the most popular philosophy/paradigm in the international field of mixed methods research (MMR). This article therefore introduces, describes, and contrasts the philosophies of the most well known pragmatists, including the three most important classical pragmatists (Charles Sanders Peirce, William James and John Dewey) and two neopragmatists (Richard Rorty and Susan Haack). It is shown that Rorty and James fit well with qualitatively driven MMR (i.?e., MMR where the qualitative component of the study is primary); Peirce fits well with quantitatively driven MMR (i.?e., MMR where the quantitative component is primary); and Dewey fits well with MMR that attempts to treat qualitative and quantitative research/philosophy equally (i.?e., equal-status mixed methods research). Importantly, it is shown here that pragmatism offers a way out of many philosophy of science quagmires facing social researchers and it offers a promising philosophy for mixed methods research practice.     

Religion und Bildungserfolg im Migrationskontext – Theoretische Argumente,empirische Befunde und offene Fragen

Religion has received extensive attention as a factor influencing immigrants’ integration. This paper examines the role of religion in explaining ethnic educational inequalities in Germany. Due to a general lack of research in this field, the paper provides an overview of existing empirical findings, specifies theoretical arguments on how religious affiliation, belief and participation possibly affect educational achievement among children of immigrants. Using data from the first wave of the “Children of Immigrants Longitudinal Survey in four European Countries” collected in 2010/11 the paper tests key arguments on the influence of religion on the educational attainment among 14-year-old immigrant and non-immigrant students at German schools. Compared to other religious groups, Muslims display lower rates of educational achievement. However, this can be largely explained by their social background and is independent from their levels of individual religiosity. Interestingly, individual religiosity has a positive effect on the educational achievement among Protestant students, whether with or without a migration background.     

Mixed-Methods-Sampling als Mittel zur Abgrenzung eines unscharfen und heterogenen Forschungsfeldes

Problems in defining the research field and in generalizing emerge in both quantitative and qualitative research. With the analysis of “fears of the future in dystopian feature films”, a multi-stage sampling strategy is presented to point out these difficulties as well as to illustrate one possible way of dealing with them. Particularly, in heterogeneous, rapidly changing and diffuse fields of research conducting mixed-method-studies can compensate for the weaknesses of quantitative and qualitative research logics. Therefore, further research should address issues of field delineation, sampling and generalization in greater detail.     

The Pragmatic Case Study in Psychotherapy: A Mixed Methods Approach Informed by Psychology’s Striving for Methodological Quality

At least as far back as Plato and Aristotle, psychology began as a stepchild of philosophy. The establishment by Wilhelm Wundt in 1879 of the first formal psychological laboratory focused on studying psychophysiological phenomena was psychology’s declaration of independence as a discipline. By positioning itself as the application of natural-science-based, empirical methods involving quantitative, group-based approaches to psychological topics, the discipline consolidated its independence and its societal status and clout. This paper first summarizes these developments, to highlight the causes of psychology’s historical resistance to qualitative case studies, and to qualitative research generally. I then briefly review three movements that have stimulated psychology to slowly but surely embrace qualitative case study research, with the addition of complementary, quantitative data: the rise of postmodern philosophy, the related “cognitive revolution” in psychology, and the “mixed methods” model of research in the social sciences that synergistically combines qualitative and quantitative methods. The result of this embrace, in the context of psychology’s established science-oriented identity, has been for psychology to add quality-of-knowledge guidelines for elevating the yield of case study knowledge. This result is illustrated by three examples: Kazdin’s (J Consult Clin Psychol 49:183–192, 1981) strategies for reducing threats to the validity of conclusions from case studies; Elliott, Fischer, and Rennie’s (Br J Clin Psychol 38:215–229, 1999) development of methodological standards for both quantitative and qualitative research; and my own work in developing the Pragmatic Case Study (PCS), which particularly reflects three of the recent trends in psychology: pluralism, pragmatism, and the mixed methods approach. Comparisons between organized social work’s and organized psychology’s approach to psychotherapy training and research is noted, with the two fields starting off in opposite directions and recently coming together.     

Ökologische Validität durch Mixed-Methods-Designs

Due to their focus on variable-oriented comparisons and large-N samples, survey methods are prone to lack information on the context-specific, practical meaning of measured constructs. This issue is explicated via the concept of “ecological validity”. A sequential quantitative-qualitative mixed-methods-study on anti-American prejudice in Germany is presented to demonstrate how semi-structured qualitative interviews (n = 22) can compensate for lacking ecological validity in standardized prejudice measurements (CATI-survey, n = 808, summer 2011). Qualitative analyses provide context-sensitive insight into the rhetorical functions of anti-American speech. They are used to generate explanatory hypotheses for correlations between anti-American, anti-Semitic, and racist prejudice in the survey data. This complementarity of research methods is closely connected to an enhanced theoretical perspective: The combination of attitude-based and speech-act-theoretical concepts of prejudice helps to increase construct validity in the example study.     

Warum die Weltgesellschaft nicht existiert. Kritische Reflexionen zu einigen empirischen und epistemologischen Problemen der Theorie der Weltgesellschaft

Use of the term “World Society” in its present connotations is becoming an accepted part of the vocabulary of globalization in academic thinking. Despite its relatively rapid rise as an analytical tool, the popularity of the term does not appear to be matched by any widespread consensus concerning its precise meaning. This paper therefore sets out to take a recapitulating look at the concept of “World Society” from both a theoretical and systematical standpoint. The aim is to offer a detailed account of the concept of World Society. Current sociological research on World Society focuses on three sets of central assumptions, which are of special relevance for its genesis: 1. Communication technologies; 2. Global diffusion of cultural/ normative patterns; 3. Functional Differentiation. This serves as the backdrop for an analysis of the epistemological limitations and modal epistemological problems of World Society Theory. Epistemic modality deals with the reality or truth-status of propositions. Due to reflections on philosophy of modality, this paper attempts to show that socio-cultural rules as such are merely “virtual”. Structures are not fixed or given. They exist only as they are instantiated in action. On this basis the paper argues that world society does not exist, because World society theory mostly overlooks implementation. It attends almost entirely to law on the books, not law in action. Synonymous with the Western metaphysical tradition world society theory presents a modern version of a Platonic theory of ideas. In a critical discussion of concepts of World Society Theory, the limits of this approach as well as noteworthy challenges for historical-sociological research on contemporary processes of globalization are identified.     

Unternehmen erfolgreich in (die) Zukunft führen

This article of the magazine “Gruppe. Interaktion. Organisation (GIO)” shows how the digital transformation changes the understanding of leadership in a fundamental and disruptive way. It highlights different approaches for business strategies and human resource management that seem necessary to succeed within the new, digital age. The digital transformation of the Haufe Group offers a valid example and is being outlined with reference to their practical experience and to scientific research. The case of the Haufe Group indicates clearly: the digital transformation requires a profound social transformation!     

Quantifizierung

The challenge in data analysis often lies in taking account of the multi-dimensionality and complexity of the data and at the same time discovering patterns, which requires reduction and simplification. Quantitizing qualitative data can serve as an additional step during data analysis to broaden the perspective and collect complementary views. Examples from research illustrate how information gathered during one data collection can generate different types of data or how qualitative data can be transformed to be analysed statistically. Practicalities of integrating qualitative and quantitative analyses are illustrated to offer good-practice examples for transformation designs (QUAL → QUAN). With the methodological reflection of research practice I evaluate consequences for the field of mixed methods research, in which the statistical analysis of codes created during an interpretive phase plays a minor role.     

Konfundierungen in Vignettenanalysen mit einzelnen d‑effizienten Vignettenstichproben

This research note deals with a design of vignette studies which is based on a single d-efficient vignette sample. To this end, we first discuss the underlying assumption of negligble interaction effects between vignette characteristics. A subsequent simulation demonstrates potential consequences of the violation of this assumption for our vignette study “Who is welcome in Germany?” (KZfSS 2016, 2).     

Karrieren nach der Rente: Karriere- und Arbeitsvorstellungen von arbeitenden Rentner*innen

The employment rate of German older workers has rapidly risen in the last 15 years. The steepest increase was found among those older than 65. The number of these working pensioners has more than doubled between 2000 and 2015. However only little gerontological and psychological research on working pensioners can be found. Companies and human resources managers seem rather unprepared, as almost no organisational career and development models exist for this group. Based on data from the survey “Transitions and Old Age Potential: Übergänge und Alternspotenziale (TOP)” the article at hand investigates older workers (age 50–65), attitudes towards potentially working in retirement. The results show that about half of the respondents consider working in addition to receiving a pension. However, they prefer part-time employment with on average 20?hours a week over full-time employment. In addition, this article discusses how the preference of this employment group fits with existing career models. We find that there is not one but several career models for working pensioners that human resource strategies should be mindful of.     

Entwicklung einer auf Resilienz ausgerichteten OrganisationskulturDevelopment of an organizational culture aiming resilience

This article examines how resilience of organizations can be enhanced by promoting their capability for adaptation. In a first step, the current understanding of the conceptualization of organizational resilience is compared to the resilience of individuals and teams. In a second step, the article also aims to illustrate the relationship between organizational resilience and organizational culture. Based on this, the applied research and development project “TeamSafe” in collaboration with a nuclear power plant is described as an example of a resilience-oriented training concept and a method for coping with unknown situations. In this project a multi-methodological approach (observational methods, video analysis and workshops) was chosen in order to identify relevant competencies and combine them with scientific findings. By involving simulator instructors and operating teams during the development process of the training concept, crucial action knowledge of operating teams in a nuclear power plant was gained by observations in the simulator and shared between different teams. This enabled the resilience-oriented development of the organization’s culture.     

Die europäische Schuldenkrise als Schub systemischer Vergesellschaftung: Von Partizipationsversprechen zu Partizipationszwang

The article presents a sociological conceptualization of the dealing with the recent sovereign debt crisis in the European Monetary Union (EMU), which is reconstructed as a push of “sociation” (vergesellschaftung in Simmel’s sense) that maneuvered populations of indebted states into de facto contractual obligations vis-à-vis their states’ creditors. Seen from this perspective, the sovereign debt crisis has led to an, if highly ambivalent, deepening of European “integration”. The article suggests a combination of Habermas’s distinction between system and life-world, which enables an interpretation of contract-like relationships as systemic mode of integration potentially harking back on the life-world, with David Graeber’s emphasis on the asymmetrical and hierarchical processes of sociation inherent in contractualized and marketized creditor-debtor relationships. Far from postulating an evolutionary development of processes of debt-related sociation that might be associated with the modernization-theoretical proclivities in Habermas’s theory, the article analyzes the role of financial market publics in creating a structure of legitimation that supported the political interpretation of the financial crisis as a sovereign debt crisis in the EMU, thus bestowing justification on the treatment of populations as “debtors of last resort”.     

How to Construct a Mixed Methods Research Design

This article provides researchers with knowledge of how to design a high quality mixed methods research study. To design a mixed study, researchers must understand and carefully consider each of the dimensions of mixed methods design, and always keep an eye on the issue of validity. We explain the seven major design dimensions: purpose, theoretical drive, timing (simultaneity and dependency), point of integration, typological versus interactive design approaches, planned versus emergent design, and design complexity. There also are multiple secondary dimensions that need to be considered during the design process. We explain ten secondary dimensions of design to be considered for each research study. We also provide two case studies showing how the mixed designs were constructed.
