A researcher compares three different type of therapy (Psychoanalytic, Cognitive-behavioral, Humanistic) to see how they affect people's depression levels. Interpret his results based on the follow data. Higher scores mean higher depression. Assume a = .05.
Mean depression score for Cognitive-behavioral group: 9.49
Mean depression score for Psychoanalytic group: 11.25
Mean depression score for Humanistic group: 11.12
(2, 89) = 3.78, p = .004, n2 = .07
Tukey post hoc tests:
Psychoanalytic vs. Cognitive-behavioral*, p=.03
Psychoanalytic vs. Humanistic, p=.49
Cognitive-behavioral vs. Humanistic*, p=.01
What is the interpretation of these results?
A People who had Cognitive-behavioral therapy had lower depression scores than people who had Psychoanalytic or Humanistic therapy.
B People who had Psychoanalytic or Humanistic therapy had lower depression scores than people who had Cognitive therapy.
C Depression scores were not significantly different regardless of the therapy type.
