Introduction “Children in psychodynamic psychotherapy: Changes in global functioning” is a study that was conducted by Fredrik Odhammar, Eva C. Sundin, Mattias Jonson, and Gunnar Carlberg as part of Erica Process and Outcome Study on children. The study was carried out with the aim of establishing the effectiveness of the participants’ global functioning following psychodynamic psychotherapy. The participants involved children who had undergone psychodynamic psychotherapy. The work of Odhammar and the other researchers will be appraised in this critique, with particular emphasis on the research topic, the theoretical coherence, and logical structure, and the research design used. Also, the major findings of the study, their validity and reliability, and their practical implications to clinical practice will be examined. Brief Summary Odhammar and other researchers carried out their study as part of the Erica Process and Outcome Study. This is a study that investigated children’s global functioning following psychodynamic psychotherapy with the main focus being to establish whether global functioning is enhanced after treatment. The researchers assessed the factors that are thought to influence global functioning, such as age, sex, type of disorder, and co-morbidities among others using quantitative and statistical methods. The participants in the study included 33 children between the ages of 5 and 10 years who had been involved in psychodynamic psychotherapy at the same time with their parents. Twenty-nine (29) of the study participants were diagnosed with some mental health disorders, whereas fifteen (15) of the participants were diagnosed with co-morbid conditions. The diagnoses were based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). The psychotherapists used CGAS and HCAM tools to measure the participants’ global functioning. From the study, the researchers showed that psychodynamic psychotherapy significantly enhanced the children’s global functioning, even though the study did not establish any significant relationship in regard to factors like age and sex that are thought to influence global functioning. The researchers also sought to disambiguate the complex relationship existing between the psychodynamic psychotherapy procedure and the enhancement in global functioning. The researchers, thus, incorporated a qualitative study approach whereby in-depth case studies were performed using data generated from questionnaires that were obtained from two therapies and filled at intervals of 3 months. The researchers sampled two such therapies, including one that reported great improvement and one that reported minimal improvement in global functioning as measured under CGAS. On evaluation, the researchers established that significant changes, such as the achievement of set goals, in the patients were not regularly captured in the measurements on the CGAS (Odhammar et al. 2011). Theoretical approaches and evaluation of the study by Odhammar et al. (2011) To justify the need for their study, Odhammar et al. (2011) researched extensively about psychodynamic psychotherapy through broad literature review. The intense research on available relevant literature was important in improving the study’s reliability and validity, in addition to bringing out th
