Examining a construct and answering the questions accordingly. The construct I chose is Post Traumatic Stress Disorder (PTSD). The assignment involves researching peer-reviewed articles, making a chart, knowing the validity types (face, convergent, divergent, criterion, incremental, prospective) well, and knowing the psychological tests such as CES-D, PHQ-9, and HRSD, mean score, reliability, PPV, Sensitivity, etc. The grammar and explanations are strictly important and references are needed as well. The prospective study needs to be clear and understandable.
