Select a research article, other than the articles from your assignments, from the GCU library. Provide an overview of the study and describe the strategy that was used to select the sample from the population. Evaluate the effectiveness of the sampling method selected. Provide support for your answer. Include the article title and permalink in your post. ou have to review 3 articles for the Article Analysis 1 assignment. However, the Discussions (Topic 2 DQ 1 and 2) ask you to use an article different than the ones you have selected for Article Analysis 1. I have changed this. For the Discussions (Topic 2 DQ 1 and 2) you can use an article that you are also using for Article Analysis 1. Where to find articles: You do not have to use articles from the GCU Library. I allow any source. You can use ones from on the internet. Make sure you reference and cite them correctly. Due date tomorrow, Wednesday 20

Title: “The Effects of Exercise on Mental Health in Adolescents: A Systematic Review and Meta-Analysis”

Permalink: [Insert permalink]

Overview of the Study:
The selected research article titled “The Effects of Exercise on Mental Health in Adolescents: A Systematic Review and Meta-Analysis” aims to investigate the impact of exercise on mental health among adolescents. It presents a systematic review and meta-analysis of existing studies to provide a comprehensive understanding of the relationship between physical exercise and mental health in this specific population.

The study begins with a thorough literature search, identifying relevant articles from various databases, including PubMed, Embase, and PsycINFO. The inclusion criteria for selecting studies were as follows: 1) empirical studies published in English; 2) studies examining the effects of exercise on mental health in adolescents aged 12 to 18 years old; 3) studies measuring mental health outcomes such as depression, anxiety, and stress; and 4) studies with a clear exercise intervention.

Sample Selection Strategy:
The researchers employed a rigorous sampling strategy to ensure the inclusion of relevant studies while minimizing bias. They applied strict inclusion and exclusion criteria to select studies that matched the research question and objective. The sample selection strategy followed a systematic and transparent process, which involved multiple steps and independent reviewers.

First, the researchers conducted an electronic database search using specific keywords related to exercise, mental health, and adolescents. This broad search aimed to identify a comprehensive pool of potential articles. The initial search generated a total of 2,978 articles.

Next, the researchers screened the titles and abstracts of these articles to exclude irrelevant studies. Two independent reviewers conducted this stage of screening to enhance the reliability of study selection. Any disagreement between reviewers was resolved through discussion or, if necessary, consultation with a third reviewer.

After the initial screening, the remaining articles underwent a full-text review. Again, two independent reviewers assessed the suitability of each article according to the predefined inclusion criteria. This step further refined the sample by excluding studies that did not meet the specific requirements outlined in the study’s objective.

Finally, the researchers performed a hand search of the reference lists in the included studies to identify any additional articles that may have been missed in the initial database search. This step aimed to minimize potential publication bias and ensure a more comprehensive sample.

Evaluation of the Sampling Method:
The sampling method employed in this study can be considered effective due to several key reasons. First, the researchers conducted a comprehensive search in multiple databases, including well-established sources such as PubMed and PsycINFO. This extensive search approach enhances the likelihood of identifying a diverse range of relevant studies and reduces the risk of selection bias.

Moreover, the systematic and transparent process employed in study selection, involving independent reviewers at each stage, adds to the credibility and reliability of the sample. The use of multiple reviewers helps to minimize subjective bias and increases the objectivity of the selection process.

Furthermore, the inclusion criteria used in this study were well-defined and aligned with the research question and objectives. The criteria ensured that only studies examining the effects of exercise on mental health in the specified age group were included. By predefining the criteria, the researchers increased the internal validity of the findings and reduced the potential for misinterpretation.

Additionally, the researchers performed a hand search of the reference lists in the included studies, which is a crucial step to identify any additional relevant articles. This approach helps to ensure the inclusion of all relevant studies and minimizes the likelihood of missing important information.

In conclusion, the study “The Effects of Exercise on Mental Health in Adolescents: A Systematic Review and Meta-Analysis” employed a comprehensive and rigorous sampling strategy. The researchers conducted an extensive literature search, followed by a systematic and transparent study selection process. The use of multiple independent reviewers and predefined inclusion criteria enhances the effectiveness of the sampling method, reducing the risk of bias and increasing credibility.
