The use of numerical/quantitative data in qualitative research studies and reports has been controversial. Prominent qualitative researchers such as Howard Becker and Martyn Hammersley have supported the inclusion of what Becker called "quasi-statistics": simple counts of things to make statements such as "some," "usually," and "most" more…

The question as to which structural equation model should be selected when multitrait-multimethod (MTMM) data are analyzed is of interest to many researchers. In the past, attempts to find a well-fitting model have often been data-driven and highly arbitrary. In the present article, the authors argue that the measurement design (type of methods…

The intersection of mixed methods and social justice has implications for the role of the researcher and choices of specific paradigmatic perspectives. The transformative paradigm with its associated philosophical assumptions provides a framework for addressing inequality and injustice in society using culturally competent, mixed methods…

A mixed methods study has the potential to produce knowledge that is unavailable to a qualitative study and a quantitative study undertaken independently. Any unique insight or "yield" from a mixed methods study may be difficult to assess in practice. However, given that integration of data or findings from different components of a…

This study investigates the latent structure of individual differences in vocational, leisure, and family interests. The participants consisted of 302 French adults who rated their like or dislike for activities based on Holland's RIASEC typology and presented in three life domains: work, family and leisure. The multitrait-multimethod model…

Quality assurance and evaluation research, like other fields of social research and its application, are confronted with a series of problems. In the present paper, I want first to give a list of such problems, although necessarily incomplete. It is then claimed that while there is no "perfect" solution to these problems, critical multiplism may…

Explores the concept of construct validity in the context of a public examination. Multitrait-multimethod analysis and factor analysis were used. Discusses the analyses in terms of theory versus practical components and experimental versus observational investigation in practical components. Sample items for the practical examinations are…

Explains the convergent and discriminant validity of two tests of science process skills with two tests of formal reasoning ability. Reports test results from elementary education majors and discusses the tests' intercorrelations. Implications related to instruction are analyzed. (ML)

Measures of 4traits (cognitive competence, social competence, social maladaption, and personal maladaption) were obtained on 157 persons with mental retardation, using 3 measurements: standardized assessment instrument, day shift staff ratings, and evening shift staff ratings. The multitrait-multimethod matrix procedure demonstrated strong…
