You design a study to evaluate the effect of a new treatment for an anxiety disorder.  In the study, one group of participants (Group 1) receive the new treatment for 1 hour per week, for 8 weeks. Another group of participants (Group 2) receive nothing for 8 weeks, they are waiting to receive the treatment later.  Before the treatment and after the treatment, you measure the level of anxiety in both groups.  At the end of the treatment, you find that both groups improved slightly, and to the same degree.  What is your conclusion?

Question 6On 10 days during the month, a group of participants rated their feelings of anxiety immediately following a 30-minute session with a counselor. On 10 other days during the same month, the same group of participants rated their feelings of anxiety immediately following a brisk 30-minute walk. The mean difference in anxiety ratings between the counselor and walk conditions could be analyzed with a1 pointindependent-samples t-test.one-way between-groups ANOVA.paired-samples t-test.one-sample t-test.

The American Association of Psychology has published a report on treatments for panic disorder.  Three different treatments—cognitive behavioral therapy (CBT), medical drugs and a combination of the two—were used in combatting two symptoms (anxiety and depression) of this disorder, as well as in patients’ amelioration (overall improvement and quality of life). The effect size of a symptom’s reduction, or the effect size of a positive marker’s increase, were measured on a scale of 0 to 1. Given these measurements of both symptoms and progress, ______.Which choice most effective uses data from the graph to complete the statement?Choose Your AnswerPreviousNextA.It appears that CBT, more than medical drugs, affords a patient with panic disorder a feeling of overall improvement as well as an improved quality of life.B.It seems that reducing anxiety, with any treatment, is the most achievable aim.C.Results suggest that only when in combination, do drugs and CBT address depression more effectively than these treatments’ separate administration.D.There appears to be strong reason to doubt the efficacy of either CBT, drugs or their treatment in combination.

You discover that a few of the psychotherapists in the clinic have decided to try out the new therapy, while others who treat similar patients have chosen to stick with the normal protocol. You can use these pre-existing groups to study the symptom progression of the patients treated with the new therapy versus those receiving the standard course of treatment. Although the groups were not randomly assigned, if you properly account for any systematic differences between them, you can be reasonably confident any differences must arise from the treatment and not other confounding variables.
