Chapter 11 Flashcards
Quasi experiment
Has some features of an experiment, but Lacks key aspects of experimental control
One group post test only design
A treatment occurs and afterword the dependent variable is measured once
One group pretest posttest design
A dependent variable is measured once before and once after a treatment occurs
Simple interrupted time series design
A dependent variable is repeatedly measured at periodic intervals before and after a treatment
Selection interactions
The interaction of a selection with another thread to internal validity
Post test only design with a non-equivalent control group
Participants and one condition are exposed to a treatment, anon equivalent group is not exposed to the treatment, and scores from both groups are obtained after the treatment ends
Pretest posttest design with a non-equivalent control group
Pre-and post treatment scores are obtained for a treatment group and a non-equivalent control group
Interrupted time series design with a non-equivalent control group
A series of pre-and post treatment scores are obtained for a treatment group and a non-equivalent control group
Switching replication design
One group receives a treatment, and a non-equivalent group initially does not receive the treatment but I stand exposed to it later in time
Program evaluation
Involves the use of research methods to assess the need for, and the design, implementation, and effectiveness of a social intervention
Needs assessment
Determines whether there is a need for a social program and the general steps required to me that need
Program theory and design assessment
Evaluates the rationale for why a program has been, or will be, designed in a particular way
Process evaluation
Determines whether a program is being implemented as intended
Outcome evaluation
Assesses a programs effectiveness
Contamination
Occurs when knowledge, services, or other experiences intended for one group are intentionally received by another group
