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. 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. Provide a detailed discussion regarding some of the potential threats that could occur to the internal validity of your study.

A few potential threats could occur such as inconsistent instruction in classes, leading to a loss of complete control of the experiment. Different levels of issues in participants could result in varying times for improvement, leaving results incomplete. Examine how these threats could reduce the validity of your study. What are some ways you could increase internal validity? What is the importance of external validity for your study?

Pressing to achieve mundane realism is a goal. Either way, both internal and external validity offer a specific look into a study and the results. What do you find most difficult about the idea of validity? What aspects of evaluating it or integrating it into research design are the most challenging and why?

What questions do you still have about experimental validity after this exercise?

FORUM 2: Experimental Validity. Experimental studies must adhere to internal and external validity conditions, ensuring widespread applicability of the established findings. Internal validity is the level of confidence that no factors sabotaged the trustworthiness of the collected data. In contrast, external validity relates to the extent of generalizability of the established findings to the whole population and other groups.

A matrix of threats could likely undermine the internal validity of the data collected in the proposed study. The most common threats include selection bias, attrition, history, maturation, and instrumentation. How can the validity of the study be maintained for both internal and external areas, to include maintaining credibility with a topic that has not been aggressively studied?

In addressing the proposed study on the effects of Brazilian jiu-jitsu on the mental health of military members, it is crucial to analyze the potential threats to internal validity. One significant threat arises from the varying quality of instruction provided in jiu-jitsu classes. As noted, inconsistent training can lead to disparities in skill acquisition among participants, complicating the measurement of psychological outcomes (Malec & Newman, 2013). Furthermore, participant variability in pre-existing conditions, such as different levels of PTSD or depression, may create an uneven baseline, affecting the study’s ability to accurately measure the effects of training over time.

Moreover, the attrition of participants during the study presents another possibility that could diminish internal validity. As noted, some participants may drop out due to multiple reasons, including a lack of improvement or personal circumstances (Patino & Ferreira, 2018). This dropout can lead to selection bias if the remaining participants differ significantly from those who left, impacting the estimated effectiveness of jiu-jitsu training on mental health.

To mitigate these threats, establishing a controlled environment that standardizes instruction, as well as ensuring the recruitment of participants with similar baseline characteristics, is essential. Implementing a robust screening process before starting the study could help ensure that participants are equitably matched in terms of prior experience and mental health status (Malec & Newman, 2013). Moreover, robust follow-up mechanisms to increase retention rates can help achieve statistical power that strengthens the findings.

Regarding external validity, the realism of the training environment must be preserved to generalize results effectively to the broader population of military personnel. Achieving a balance between laboratory controls and real-world applicability helps maintain realistic expectations of jiu-jitsu's benefits in mental health. Understanding the dynamics of martial arts and how they can be integrated into military training could further enhance external validity (Patino & Ferreira, 2018).

Considering whether internal or external validity holds greater importance largely depends on the research focus. If the study aims for precise relationships between variables, internal validity becomes paramount. However, if the goal is to translate findings into practical applications for diverse groups, external validity is essential. Recognizing that both validities offer valuable insights for different aspects of research helps during the study's design process.

One of the most challenging aspects of establishing validity is recognizing that perceived clarity may often be misleading. Assumptions that all variables have been accounted for can lead to significant oversight in research design. When humans are involved, the complexity of individual experiences and behaviors can introduce variability, which is difficult to control (Patino & Ferreira, 2018).

In conclusion, developing a valid study on the effects of Brazilian jiu-jitsu on military mental health is a multifaceted task. Addressing threats to both internal and external validity from the outset will be vital to establishing credible findings that can influence therapeutic practices within military contexts. Future inquiries could benefit from exploring these intricacies while continuing to address the evolving nature of mental health treatment through innovative therapeutic modalities.
