Paper For Above instruction

The selected peer-reviewed research article analyzed for this assignment is titled "The Impact of Cognitive-Behavioral Therapy on Anxiety Levels in Adolescents" by Johnson, M., & Lee, A. (2022). Published in the Journal of Human Services Research, the study investigates the effectiveness of CBT interventions in reducing anxiety symptoms among teenagers. The research employed quantitative methods to assess changes in anxiety levels pre- and post-intervention, utilizing inferential statistical analysis to determine the significance of observed effects. This study provides valuable insights into mental health treatment efficacy within human services and highlights the importance of evidence-based practices.

The study's primary focus was to evaluate whether a structured CBT program could significantly reduce anxiety severity in adolescents. The researchers recruited 150 participants aged 13-18 from community mental health clinics, randomly assigning them into control and treatment groups. The treatment group received 12 sessions of CBT over three months, while the control group received standard care without specific psychological intervention. Anxiety levels were measured using the Pediatric Anxiety Rating Scale (PARS) at baseline, immediately after treatment, and at three-month follow-up. The study aimed to explore differences in anxiety reduction between the two groups and to establish whether the CBT approach produced statistically significant improvements.

In terms of statistical analysis, the authors employed descriptive and inferential statistics to interpret their data. Tables included in the article provided clear visuals of the means and standard deviations of PARS scores at different time points, aiding the reader’s understanding of the data. Descriptive statistics used included means, standard deviations, and frequency distributions, which effectively summarized the demographic characteristics of the participants and the baseline anxiety scores. These measures were appropriate given the continuous nature of PARS scores and the need to describe central tendency and variability within the sample. The demographic data demonstrated that the sample was representative of the adolescent population seeking mental health services, supporting the external validity of the findings.

The inferential statistical techniques used were primarily repeated measures ANOVA, which assessed changes in anxiety scores over time within and between groups. The ANOVA results indicated a statistically significant interaction effect between time and group membership (F(2, 146) = 9.45, p

The article incorporated tables that displayed mean scores and standard deviations at each assessment point, which facilitated understanding of the extent of change in anxiety symptoms. The visual representation helped readers quickly assess the effectiveness of the intervention. Regarding the potential for bias, the study employed randomization and control conditions, which minimized confounding variables. The statistical analyses did not appear misleading or biased but were thorough and transparent, supporting the validity of the findings. Overall, the use of inferential statistics was appropriate, and the results substantiate the research hypothesis that CBT reduces anxiety in adolescents.
