Summary of the study

Summary of the study

The study conducted by Janvnbakht, Hejazi, and Ghasemi (2009) aimed to evaluate the ways in which Yoga relieves symptoms associated with depression and anxiety in women patients referred to a yoga clinic.

The authors conduct the study to determine the perception that yoga acts as one of the effective methods of stress management that alleviate anxiety and stress disorders.

The study used women referred to the yoga clinic from July 2006 to July 2007 as a convenient sample for the study.

The cases were evaluated during the time of admission using a personal questionnaire alongside Spielberger and Beck tests.

A control group was assigned to the participants and experiment randomly.

The control group did not get any yoga classes. Evaluation of the two groups was done repeatedly after two months throughout the study period (Bick & Graham, 2010).

The cases were evaluated during the time of admission using a personal questionnaire alongside Spielberger and Beck tests. A control group was assigned to the participants and experiment randomly. The participants used as the experimental group took part in yoga classes twice a week for 90 minutes for two months. The control group did not get any yoga classes. Evaluation of the two groups was done repeatedly after two months throughout the study period (Bick & Graham, 2010).

Summary of the study (cont'd)

The results revealed that the average prevalence of anxiety and depression, reduced significantly in the experimental groups, both pre-yoga intervention (12.82 to 7.9) and post Yoga Intervention (10.79 to 6.04).

This represented a prevalence decrease of p=0. 13. Comparing the results of the experimental and control group showed a significant difference in the influence of yoga intervention.

There was a significant decrease in anxiety of women who took part in the yoga intervention (p=0. 03) and a decrease in trait anxiety of less than 0.001.

After the one-year, the authors found that participating in a two-month yoga intervention result in a significant reduction in the perceived level of depression and anxiety in women suffering from anxiety related disorders.

the authors of the study suggested that Yoga intervention may be considered as one of the complementary and alternative therapies in the management of depression and/or anxiety related disorders and associated symptoms (Kent & McCormack, 2010).

Critical Appraisal of the Research Article

The study conducted by Janvnbakht, Hejazi, & Ghasemi (2009) used blinding method to ensure the internal validity of the study is maintained.

Russ & Niec, (2011), acknowledged that blinding minimizes the occurrence of prognostic differences between the different groups being studied.

These biases reduce threats to internal validity during the assessment of the results and subsequent differential interventions.

The authors failed to maintain the internal validity of the study as the control group is aware of their status during the study.

They do not receive any yoga classes for the time of the study to create the effect of yoga intervention to patients with anxiety and depression disorders.

Janvnbakht, Hejazi, & Ghasemi (2009) have clearly identified the purpose of their study. They have also stated the importance and relevance of the research topic to the current evidence-based practice.

The use of participants with an already diagnosed illness facilitates the study of the effectiveness of the yoga intervention in alleviating disorders and symptoms associated with anxiety and depression.

Critical Appraisal of the Research Article

The study conducted by Janvnbakht, Hejazi, & Ghasemi (2009) used blinding method to ensure the internal validity of the study is maintained. Individual's perception and knowledge towards a phenomenon affect the results of a study. This increases the risks of inaccurate findings when conducting research. As such, blinding proves effective as it eliminates selection bias. Russ & Niec, (2011), acknowledged that blinding minimizes the occurrence of prognostic differences between the different groups being studied. These biases reduce threats to internal validity during the assessment of the results and subsequent differential interventions. However, factors like history, maturation, mortality, testing, and interaction between the subjects threaten the internal validity and the blinding strategy adopted in the study.

The authors failed to maintain the internal validity of the study as the control group is aware of their status during the study. They do not receive any yoga classes for the time of the study to create the effect of yoga intervention to patients with anxiety and depression disorders. According to Russ & Niec, (2011), the major criteria that ensure internal validity during a study are blinding, adequate handling of the participants who drop out or withdraw from the study, and random allocation of treatment to… [END OF PREVIEW]
