The Effectiveness Of Cognitive Behavior Therapy

Name Course Instructor Date The effectiveness of Cognitive Behavior Therapy (CBT) in lowering the patient health questionnaire-9 (PHQ-9) scores in adults with depression Statistical Test: The test that I would use is the Independent Measures t-test. Purpose: To determine the effect of Cognitive Behavior Therapy (CBT) on the patient health questionnaire-9 (PHQ-9) scores in adults with depression. Independent variable: CBT is the independent variable since this is the intervention used to determine its effect on depression as indicated by the PHQ-9 scores. Dependent variable: The score on the depression questionnaire, where the participants are treated with CBT and complete the depression questionnaire. Method: Participants selected are between 18 and 45 years of age, both male and female. CBT intervention is used to determine whether there is a decrease in the PHQ-9 levels, and lower scores indicate there is improvement among people diagnosed with depression. There would be two groups where participants receive the CBT intervention, and in the other group there is no therapy intervention. The PHQ-9 scores would be compared between the two groups to determine whether CBT affects the questionnaire scores. The PHQ-9 tool not only allows one to investigate of patients with depressive disorders through a self-assessment survey, but also allows determining the severity of depression, which is helpful in follow-up treatment. The PHQ-9 (Patient Health Questionnaire) consists of 9 items that evaluate the presence of depressive symptoms (corresponding to the DSM-IV criteria) present in the last 2 weeks. 2) Statistical Test: The test that I would use is the Paired T-Test effect Purpose: To determine the effect of music therapy on patients’ anxiety among long-term care patients where pain is assumed to increase anxiety and a positive mood reduces anxiety. Independent variable: The independent variable is the music therapy used to determine its effect on anxiety levels. Dependent variable: The dependent variable is the anxiety level, and anxiety may also increase the risk of depression. Method: The Beck Anxiety Inventory (BAI) is used to measure the anxiety levels at the pre and post intervention anxiety levels and scores are compared before and after intervention. All the participants in the study are long-term care patients who consent to participate voluntarily. Using the paired t-test the mean scores of anxiety levels at pre and post intervention is used for group comparisons. 3) Statistical Test: The test that I would use is the analysis of Variance (ANOVA) Purpose: To determine the impact of binge eating disorder on obesity where the eating behaviors are considered in pre-surgical evaluation to measure binge eating. Independent variable: The independent variable is binge and compulsive eating b...
