This debate will examine Dr. Jeremy D. Jewell’s and Dr. Kevin D. Stark’s research projects. This study was published in the Journal of Child and Family Studies with the title “Comparing the Home Environments of Teenagers with Conduct Disorder or Depression.” The authors want to know how adolescents with conduct disorder (CD) and depressive disorder grew up in different environments. The study is based on the youth’s diagnostic and home situation, which are considered independent factors.
The design adopted for the creation of this study was quasi-experimental. Initially, the participants were divided into two groups: those diagnosed with Major Depressive Disorder or Dysthymic Disorder without a CD diagnosis, and those diagnosed with CD (Jewell & Stark, 2003, p. 81), with both groups representing the youth’s varied diagnosis. Throughout the investigation, the researchers interfered in numerous tests and interviews with the adolescents to collect information relevant to the study.The design used to create this study was quasi-experimental.

Throughout the inquiry, the researchers intervened in a variety of tests and interviews with the teenagers in order to acquire data for the study.
Stratified random sampling is a type of random sampling in which the researchers decide at random after gathering information about the study participants (Morling, 2021, pp. 188-189). The researchers picked a specific treatment center in the southern United States for their study. They settled on the two disorders for which the participants were diagnosed and the age range in which they were to be found (Jewell & Stark, 2003, pp. 80-81). After these three criteria were established, the researchers did not decide how many individuals would be classified as male or female, what the average age would be, or how they would identify themselves based on their ethnicity. These later demographics were chosen at random.
Several strategies used to provide the survey validity are revealed during the study’s development. One of these techniques involves psychiatrists (Jewell & Stark, 2003, p. 81), who supervise all researchers as well as all choices and findings.The Self Report Measure of Family Functioning (SRMFF) was used by the researchers in this study (Jewell & Stark, 2003, p. 81). This tool enables researchers to consider the scales and subscales that each study participant offers concerning the condition with which they have been diagnosed.
