Document Summary

Behavioral diary: a self-report data collection strategy where individuals record their behaviors and associated feelings as they occur. Pretest-posttest design: a within-subjects design where participants are measured before and after exposure to a treatment or intervention. Baseline measurement: the participants" initial assessment at the beginning of a study. Longitudinal designs = within-subjects design where we repeatedly measure participants over an extended period of time. Repeated-measures design: a type of within-subjects design where participants are exposed to each level of the independent variable and are measured on the dependent variable after each variable; unlike the pretest-posttest design, there is no baseline measurement. Answers specific types of research questions can naturally measure participants" behaviors/attitudes/etc. Attrition/mortality: the differential dropping out of participants from a study. Testing effect: a threat to the internal validity of a study where participants" scores may change on subsequent measurements simply because of their increased familiarity with the instrument.
