\fEXCERPT FROM THE RESEARCH ARTICLE2 The final sample consisted of 74 foster parents. . . . The foster children of parents in the sample were mostly boys. . . . Qualified participants were randomly assigned to either an intervention or a control group. . . . The intervention period. . . continued for two weeks. Parents in the intervention group received the Anger Outbursts DVD and were instructed to view the training materials at least once a week. Parents in the control group received no materials during this time. p. 138 138 The Parent Knowledge questionnaire included 20 multiple-choice and true-false items based on content from all segments in the Anger Outbursts program. . . . Scores were reported as the percentage of items correct out of 20. High scores on this measure indicated greater knowledge about anger issues in children. The Parent Perception questionnaire included [a measure of] parents' confidence in having the relevant parenting skills (three items, for example, "I can recognize the different types of anger outbursts in children"). Parents rated on a four-point scale (1 = not at all; 2 - a little; 3 = mostly; 4 = very much). . . . Scores were reported as the average rating over all items. Table 1 Mean Performance on Parent Knowledge and Confidence Scales at Posttest for the National Sample of Foster Parents Intervention Control M SD n M SD Parent knowledge 71.32 12.39 34 61,38 9.41 40 Parent confidence 2.99 0.42 34 2.84 0.49 40 Standardized mean difference statistic (d ) = 0.91, bd = 0.33. STUDY QUESTIONS Factual Questions'd - 0.33. STUDY QUESTIONS Factual Questions 1. What is the average response for Parent knowledge for the Intervention group at posttest? 2. What is the average response for Parent knowledge for the Control group at posttest? 3. What is the value of d for the difference between your answers to Questions 1 and 2? 4. According to the information in Exercise 5.5, the effect size in your answer to Question 3 should be labeled as small. Is this statement true or false? Explain your answer. 5. The mean Parent confidence score for the intervention group exceeds the mean Parent confidence score for the control group by how many points? 6. What is the value of d for the difference in your answer to Question 5? (Hint to calculate it yourself: The average standard deviation equals 0.42 + 0.49 = 0.91 + 2 = 0.455.) 7. According to information in Exercise 5.5, the effect size in your answer to Question 6 should be labeled as small. Is this statement true or false? Explain your answer. p. 139 139 8. Even though it is becoming increasingly common to report effect sizes for the difference between means, many researchers still do not report them. To help in the interpretation of the differences between means, you can usually compute the values of d from the statistics that are given in an article. To practice doing this, check the value of d for the Parent knowledge means by following Steps A, B, C, and D below. A. Subtract the control group's Parent knowledge mean from the intervention group's Parent knowledge mean. What value do you get? B. Compute the mean of the two standard deviations for Parent knowledge (i.e., sum them and divide by 2). What value do you get? C. Divide your answer to Step A by your answer to Step B. What value do you get? D. Does your answer to Step C equal the value in the footnote in the table? Questions for Discussion
