Chinese Journal of Behavioral Medicine and Brain Science 2014;(11):1030-1032
Objective To evaluate the effect of the miracle questions in solution?focused brief therapy on memory tend and emotional stage in a non?clinical situation in college students. Methods A quasi?experimental design was adopted,and two kinds of materials for self?coaching( solution?focused,problem?focused) were devel?oped according to the previous researches. Seventy?two subjects were randomly divided into two groups,receiving the miracle questions in solution?focused brief therapy( The miracle question group,thirty?six subjects) or problem?focused coaching intervention(problem?focused group,thirty?six subjects).Exception memories number and positive and negative emotion level were evaluated between the two groups. Results The subjects receiving the miracle question group write more exception memories (3.67±2.07) than problem?focused group (1.61±1.18) ( t=5.178, P<0.01) . There was no significant difference in the positive and negative emotion level between the two groups(P>0.05) . Conclusion The miracle questions in solution?focused brief therapy can trigger the subjects to exceptional memories .This suggests that in practical application,questions order has impact on the effect of consultation. Be?fore asking exception question,miracle questions should be asked in the use of solution?focused intervention.
