The children are asked to rate their pain on an unstructured line scale, then the children are randomly assigned in equal numbers to two psychological intervention groups: the self-reward group and the imagination group. In the self-reward group, the children give themselves positive self-statements for enduring pain, such as “I’m a brave person.” In the imagination group, children are taught to imagine situation in which they experience pleasure when they are experiencing pain. Half of each group is given pain pills in addition to the psychological intervention, while the other half of each group is given a placebo. At the end of two weeks, the children are again asked to rate their pain on the same scale. The difference between the first pain rating and the second one is presented in the analysis printout below. A larger difference score means a greater reduction in pain, as the first rating should have been larger than the second one. Medication Pain PillsPlaceboPsychological InterventionPositive Self-Reward4.45(.80623)4.35 (.47434)4.40(.64584)Imagination5.65(.66875)4.525(.74954)5.0875(.90057) 5.05(.94799)4.4375(.61705)  ANOVA Summary Table SourceSum of Squares dfMean Square F-ratio Prob.Psychological Intervention4.72714.72710.035.003Medication3.75213.7527.965.008Psychological Intervention X Medication2.62712.6275.576.042Error16.95636.471  Total928.18840    Social Science Psychology PSY 270 Share QuestionEmailCopy link Comments (0)
