CHAPTER 5 Experimental and Quasi-Experimental Designs for Researchl DONALD T. CAMPBELL Northwestern University JULIAN C. STANLEY Johns Hopkins University In this chapter we shall examine the validity of 16 experimental designs against 12 com­ mon threats to valid inference. By experi­ ment we refer to that portion of research in which variables are manipulated and their effects …

The quasi-experimental study was used to investigate two groups of three classes. The first group had traditional face-to-face classroom lecture sessions digitally (audio) recorded and had these audio recordings made available to them online.
A non-experimental study picks up the slack from an experimental design. As discussed earlier, to study the effects of gender, you have to be able to manipulate a person’s gender. Other examples
Design. In a quasi-experimental study design, data on behavioural determinants were collected at baseline, four weeks and six months after the intervention in both the intervention and control group. Children completed consecutively three questionnaires in which knowledge, awareness, skills, attitude, emotion, subjective norm and intention towards the two target behaviours were assessed
Quasi-experimental studies are increasingly used to establish causal relationships in epidemiology and health systems research. Quasi-experimental studies offer important opportunities to increase

Quasi-experimental Study Designs Quasi-experimental studies provide an alternative to experimental and observational designs, falling somewhere in the middle on the internal validity spectrum—providing less than an experimental design but more than an observational study.
In strengthening social work’s ability to improve lives and communities, experimental design can play a critical role in helping stakeholders better understand what works in achieving positive impacts. Experimental design studies aim to test whether a specific “intervention” (or “treatment

A two-group study is the simplest design that incorporates a number of experimental control techniques. Let’s look at some data that might be recorded from this study (see
In the study of infectious diseases and, in particular, in the study of infection control and antibiotic resistance, the quasi-experimental study design, sometimes called the pre-post-intervention design, is often used to evaluate the benefits of specific interventions.

The investigators set up an experimental study (e.g. a randomised controlled trial, see below) and collect and analyse data, which will support or disprove the hypothesis.
Many of the benefits and limitations to quasi-experimental research have been alluded to in previous modules in this series. Following is a summary regarding both the advantages and the limitations or disadvantages of using quasi-experimental research approaches.

Quasi-experimental designs (QED) can still help researchers understand the impacts of a policy or program. What makes a QED “quasi” is the fact that instead of randomly assigning subjects to

Quasi-experimental studies are research designs that evaluate human behavior. Sociologists and psychologists often perform quasi-experimental research to study individuals within the same environment facing similar circumstances.
The experimental and quasi-experimental designs, along with their strengths and drawbacks, are discussed in this chapter. EXPERIMENTAL DESIGN Regular use of control groups in psychosocial and educational research dates back to about 1908. This is quite a bit later than its first use in the physical and biological sci-ences. Boring (1954) traced the recorded use of experimental controls back to
Methods: The study used a prospective, quasi-experimental design with an interrupted time-series analysis to collect data from 781 government health sectors (556 healthcare facilities, 196 district health offices, and 29 zonal health departments) selected from developing and emerging regions in Ethiopia.
A quasi-experimental design by definition lacks random assignment, however. Assignment to conditions (treatment versus no treatment or comparison) is by means of self-selection (by which participants choose treatment for themselves) or administrator selection (e.g., by officials, teachers, policymakers and so on) or both of these routes.”

A quasi-experimental design DOES NOT permit the researcher to control the assignment of participants to conditions or groups. RANDOM ASSIGNMENT TO GROUPS IS THE BASIC DIFFERENCE BETWEEN TRUE AND
valid explanations, the ways in which experimental and quasi-experimental research designs seek to meet these criteria, and the difficulties that can sometimes result in invalid conclusions. By the end of the chapter, you should have a good grasp of the meaning of causation and the logic of experimental design. Most social research, both academic and applied, uses data collection methods other

A type of quasi-experimental design that is generally better than either the nonequivalent groups design or the pretest-posttest design is one that combines elements of both. There is a treatment group that is given a pretest, receives a treatment, and then is given a posttest. But at the same time there is a control group that is given a pretest, does
