 PICOT Question  Can overweight and obesity among teenagers be prevented or managed successfully through physical activity programs after six months than no intervention at all?  Specific Research Approach  The main research method that will be used in this study is qualitative approach. Qualitative research can be described as a data gathering approach that entails in-depth inquiry of human perceptions, attitudes, and experiences. This research also seeks to examine associated processes within the contexts that certain phenomena take place (Langford, 2012). The utilization of qualitative research approach results in the development of value-based understanding of motivations and behaviors. There are various ways in which qualitative design will be implemented. This type of research approach is reliant on observations and assessments that subjectively measure the participants’ introspections, interpersonal interactions, as well as those who have relevant communities (Langford, 2012). The process of reporting this research is highly supported by verbal and visual descriptions, quotations, as well as interpretive coding.  The primary reason of which qualitative research has been selected is that it gives room for access to detailed feedback from the subjects and circumstances. In the past, the process of data gathering and analysis highly over depended on subjective evaluations (Langford, 2012). Moreover, qualitative approach provides insights into the attitudes, behaviors, and motivations on issues related to physical activity as a way of educing obesity prevalence among adolescents. This process will give room for in-depth evaluation of issues that are being researched. Moreover, qualitative approach enables the researcher to investigate highly-sensitive information. Further, qualitative design is a useful tool for undertaking comprehensive assessment on the basis of interpersonal interactions over an extended period of time.  Data Collection Method  Interviews will be used as the main data gathering methods for this study. In particular, the participants will be administered with structured interviews, which will have a list of questions read out and the responses noted down (Gratton & Jones, 2014). Structured interviews will ensure that the respondents complete the questionnaires on time and seek clarification over questions that may seem unclear or ambiguous. Structured interviews will enable the participants to express their experiences in their own words on what they feel about the efficacy of physical activities in reducing obesity prevalence. This process will enable them to explain and elaborate on any area of specific interest or significance (Gratton & Jones, 2014). Furthermore, the interview method will be insightful in many ways since it offers the researcher with perceived causal inferences from the respondents, as opposed to the researcher’s point of view. This process allows the respo0ndent to become more of an informant, who provides data from their own lived experiences and perspective. Further, the interview method will be used as a tool to provide avenues through which more important, yet unexpected data will emerge (Gratton & Jones, 2014). This is especially the case when it comes to face-to-face interviews, which enable the researcher to evaluate the respondent’s body language, facial expressions, and voice tonal variations.  Steps to Ensure Data Quality  Data quality is critical in realizing credibility of study. As such, there are various steps that will be taken to ensure quality of the data gathered. First, a data auditing process will be undertaken. The auditing process involves comparing samples of reported data for earlier time period with the source’s data records for the current period. The main assessment methods for data auditing will include triangulating with other data sources, conducting documentation reviews, and verifying and cross-checking (Radhakrishna et al. 2012). In addition, reliability will be ensured by conducting repeated measurements to ensure that they are consistent. Validity refers to the closeness between the values offered and the true values. Validity will be attained through careful designing of the structured interview questions, and conducting field tests.    References  Gratton, C., & Jones, I. (2014).
