The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959). [1] It organizes convergent and discriminant validity evidence for comparison of how a measure relates to other measures.
A wide range of research methods are used in psychology. These methods vary by the sources from which information is obtained, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they collect qualitative data, quantitative data or both.
Microgenetic design (a.k.a. microgenetic method) is a scientific method in which the same setting is studied repeatedly in order to observe change in detail.In contrast to cross-sectional and longitudinal designs, which provide broad outlines of the process of change, microgenetic designs provide an in-depth analysis of the behavior of the system while it is changing.
Often the term "framework" is used as a synonym. A method is a still more specific way of practically implementing the approach. Methodologies provide the guidelines that help researchers decide which method to follow. The method itself may be understood as a sequence of techniques. A technique is a step taken that can be observed and measured.
Q methodology is a research method used in psychology and in social sciences to study people's "subjectivity"—that is, their viewpoint. Q was developed by psychologist William Stephenson . It has been used both in clinical settings for assessing a patient's progress over time (intra-rater comparison), as well as in research settings to ...

This method represents the most extreme form of intervention in observational methods, and researchers are able to exert more control over the study and its participants. [2] Conducting field experiments allows researchers to make causal inferences from their results, and therefore increases external validity.
An important aspect of the descriptive phenomenological method in psychology is the way by which it distinguishes itself from those approaches that are strictly interpretive. [9] In this, Giorgi closely follows Husserl who proposes that "being given and being interpreted are descriptions of the same situation from two different levels of ...
