Simulated Research Study #3 Researchers and clinicians are concerned that the current treatments being offered for alcohol dependence are not resulting in a high enough percentage of successful outcomes. A complicating factor is that many clients experience depression during treatment for alcohol dependence. Mindfulness Therapy has demonstrated efficacy for the treatment of depression. The purpose of the study is to determine the efficacy of adding Mindfulness Therapy to the standard treatment program. Will the addition of Mindfulness Therapy for clients with alcohol dependence improve the efficacy of treatment? The researchers designed a study using a convenience sample of 40 participants who have entered treatment for alcohol dependence. The participants were randomly assigned to one of two treatment groups, the standard treatment program or the standard treatment program plus Mindfulness Therapy. Participants will receive treatment for 16 weeks and then complete the Alcohol Dependence Scale (ADS). The treatment groups are considered equivalent at the beginning of the study based on random assignment to groups. The null hypothesis states there will be no difference in scores on the ADS between those who receive the standard treatment program and those who receive the standard treatment program plus Mindfulness Therapy. The researcher used a paired or correlated groups t-test to analyze the data. The scores on the ADS for the two treatment groups are: Standard Treatment Standard Treatment & Mindfulness 14 18 7 12 11 17 8 12 8 4 3 10

What type of study design is used? Please explain. I believe for this research type the study design that was used was independent-groups t-test. Because the study involves comparing the means of two different samples.
COUC 515 Does the study design accurately test the null hypothesis? The study design does accurately test the null hypothesis. Is the correct statistical test used to analyze the data? Why? Why not? The statistical test of choice was correct when analyzing data. Because the study proves that the statistical test helps to deteremine the difference between scores to help reveal if the null hypothesis is accepted or rejected. Regardless of whether or not the correct statistical test was used, are the results statistically significant? Social science research uses a p value of .05 to determine statistical significance. Because the probability value (p-value) is p= 0.137, which is a higher than the 0.05 level of significance which proves that the results do not prove statistically significants. Does the researcher reject or fail to reject the null hypothesis? The researcher fail to rejectthe null hypothesis What are the implications of the results for the study and the counseling field? The conclusion that can be drawn from the result is there is no difference with scores between the two groups (thoses on the ADS who get standard treatment and those who receive Mindfulness therapy).
