FORUM 1: Using a topic of interest to yourself, briefly

Describe a proposed research study you would like to conduct. The effects training Brazilian jiu-jitsu has on the mental health of military members. Within the military, there are several factors that may contribute to depression and stress. This study would look into the positive effects training jiu-jitsu has on military members and how it could reduce the depression, or PTSD symptoms a member may have or display. Provide a detailed discussion regarding some of the potential threats that could occur to the internal validity of your study.

A few potential threats that could occur could be that the classes provided may not all be of the same instruction or level of instruction resulting in inconsistent or loss of complete control of the experiment. Also, the different levels of issues could have some members taking longer to show any signs of improvement to symptoms, leaving the results incomplete. As mentioned by Malec and Newman, (2013), “the degree of control affects the internal validity of the study.” Examine how these threats could reduce the validity of your study and possibly make the study invalid.

The results could not show an accurate representation in the impact the martial art could have on someone who is battling depression or PTSD and erode the importance that would be shown of the positive impact doing the martial art would have. Not having a base line for what schools would be approved prior to start could hinder results if the class instructions are not consistent with each other and this independent variable would impact the results. The dependent measures would need to be controlled and the baseline of what symptoms and at what level of care would also need to be factors in the experiment. What are some ways you could increase the internal validity? A few ways to increase internal validity could be to be sure to use the correct experiment model.

To have a high level of validity, the experiment needs to have the maximum control over variables and the experiment should be designed to keep the independent variable being the only variable to have differences. (Malec and Newman, 2013). Eliminating the possibility of errors within the study is another way to increase internal validity, though there may be some errors that cannot be controlled. What is the importance of external validity for your study? Having the highest level of realism can help with a high degree of external validity. (Malec and Newman, 2013). Not substituting the martial art class with other exercises or a different martial art would help keep the external validity for the study.

Pressing to achieve mundane realism is a goal and as mentioned by Malec and Newman, (2013), “need to not re-create the phenomenon down to the last detail; instead, we aim to make the laboratory setting feel like the real world.” Making it as real as possible, from those who have the symptoms to the realism of the jiu-jitsu classes, keeping a balance between the two will help. Is internal validity or external validity more important for your study? I think it would depend on the study being conducted.

If the study wanted to focus on independent variables than internal validity would be more important. If the study wanted to see results beyond the conditions of the study than the external validity would become more important. Either way both offer a specific look into a study and the results. What do you find most difficult about the idea of validity? Thinking that something is clear may not mean that it is.

The validity of a study could have several issues with someone who wants their hypothesis to be true and accurate. Having total control of both external and internal factors may be close to impossible if you are dealing with people, as several factors could come into play when people are involved. What aspects of evaluating it or integrating it into research design are the most challenging and why? Integrating validity is challenging because you may have more than one independent or dependent variable that needs internal validity. Trying to get it to fit one of the designs can also be difficult due to not understanding the context completely or losing focus on what the hypothesis is asking.

What questions do you still have about experimental validity after this exercise? A few questions I have would be when people are involved, such as within the study that I would like to conduct, how can you avoid false results? Also, how can the validity of the study be maintained for both the internal and external areas, to include maintaining credibility with a topic that has not been aggressively studied?

Paper For Above Instructions

The study I propose aims to explore the impact that training in Brazilian jiu-jitsu (BJJ) can have on the mental health of military personnel, particularly focusing on conditions such as depression and Post-Traumatic Stress Disorder (PTSD). The motivation for this study stems from a growing body of evidence suggesting physical activities like martial arts can provide mental health benefits, including improvements in mood and reductions in anxiety (Martínez-Ros et al., 2020). This study proposes to assess these benefits specifically within the military context, where members encounter unique stressors that can adversely affect their mental well-being.

One of the primary factors contributing to mental health issues among military personnel includes the psychologically demanding environment they operate in, which can lead to both acute stressors and chronic mental health conditions (Hoge et al., 2006). As indicated by research from the Department of Veterans Affairs, rates of PTSD among veterans can range from 10% to over 30%, depending on the service era (Naseer et al., 2020). Despite recognition of these concerns, traditional therapeutic approaches can be met with resistance by service members who may perceive them as stigmatizing. However, engaging in martial arts may promote resilience and provide a nontraditional outlet for trauma management (Patterson et al., 2021).

To assess this, I propose a randomized controlled trial involving military personnel who express an interest in participating in BJJ classes over a six-month period. Participants would complete baseline assessments using standardized tools for measuring symptoms of depression and PTSD, such as the Patient Health Questionnaire (PHQ-9) and the PTSD Checklist for DSM-5 (PCL-5). Randomization would help eliminate potential selection biases, ensuring that participants are equally distributed across differing levels of experience with martial arts.

While executing this study, several potential threats to internal validity must be acknowledged. One significant concern would be the variation in instruction quality across different martial arts classes, as not all instructors may deliver the same standard of training (Helgeson & Cohen, 2019). This inconsistency could lead to differential outcomes among participants, skewing the data and impacting the findings. To mitigate this threat, it would be essential to standardize instruction quality by selecting certified instructors who have undergone specific training in delivering BJJ to military personnel.

Another potential threat is attrition, where participants drop out of the study before completion (White et al., 2021). Retaining participants is critical to maintaining the study's internal validity, as dropout can introduce bias. Strategies to reduce attrition might include providing consistent communication throughout the study and ongoing encouragement from coaches, as well as taking steps to create a fostering and supportive training environment.

Moreover, participant variability could affect the study outcomes. Different mental health conditions may manifest differently, and some participants may require more time than others to show signs of improvement (Huang et al., 2019). To address this issue, careful tracking of individual progress and employing robust statistical methods to control for this variability would be essential during data analysis, allowing us to draw meaningful conclusions.

Improving internal validity might involve implementing a controlled study design that eliminates extraneous variables impacting the outcomes. One way to achieve this is by ensuring that participants complete the same type and duration of jiu-jitsu classes. Creating a defined schedule, with classes taking place at the same time and with the same duration each week, could minimize variability in class exposure. In addition, using validated assessment tools at regular intervals would help to keep track of changes in mental health symptoms over the study period.

Regarding external validity, representing a diverse sample of military personnel will allow for greater generalizability of the results. The chosen BJJ classes should be representative of the training that would typically be available to service members. By ensuring that classes reflect real-world scenarios that military personnel may encounter, external validity can be enhanced as the findings will be applicable to similar contexts beyond the study population (Hinton et al., 2022).

Balancing internal and external validity is essential for this study. While high internal validity ensures that the observed effects can be attributed to the BJJ intervention and not other factors, strong external validity indicates that these results can be replicated in other military settings. Ultimately, while internal validity may take precedence in determining the effectiveness of the intervention, external validity ensures that these findings can benefit military members facing similar mental health challenges across different environments.

In conclusion, the proposed research study aims to rigorously investigate the positive impact that training in Brazilian jiu-jitsu may have on the mental health of military members suffering from depression and PTSD. Identifying and addressing potential threats to internal validity will be critical for ensuring that the findings are reliable and can ultimately inform interventions that can improve the mental well-being of those who serve in the armed forces.
