Behavioral experimentation in field settings: threats to validity and interpretation problems

摘要: Publisher Summary Experimenter control over the experimental conditions is part of nature single-subject research and includes effective interventions, environmental control, reliable measurements. In pre- post-treatment assessments, data from current changes directly related to interventions are used as indications improvement. The reliability effectiveness a procedure has been proven by multiple replications design, which provides clinicians with information about exact necessary for be effective. Field is, however, especially vulnerable both internal external validity threats; minimize confounding variable effects, special technical precautions should taken. This chapter describes methodology treatment research, based on deinstitutionalization normalization processes. It discusses design aimed at reducing threats an actual field group experiment staff training. also explores problems concerning interpretation study results.
