Brusser and Janosy wanted to explore
the effectiveness of a new relaxation/biofeedback intervention on menopausal symptoms. They invited women who presented themselves in an outpatient clinic with complaints of severe hot flashes to participate in the study of the experimental treatment. These 50 women were asked to record, every day for 3 weeks before the intervention, the frequency and duration of their hot flashes. The intervention itself involved five 1-hour sessions over a period of 1 week. Then, for the 3 weeks after the treatment, the women were asked to record their hot flashes again every day. At the end of the study, Brusser and Janosy found that both the frequency and average duration of the hot flashes had been significantly reduced in this sample of 50 women. They concluded that their intervention was an effective therapy in treating menopausal hot flashes. What is the independent variable in this study?
Relaxation/bio feedback
Tracking of the hot flashes
Menopausal symptoms
