The student incorporates source material that is relevant and appropriate to the posed research question, effectively referencing systematic reviews and meta-analyses that support the efficacy of cognitive-behavioral therapy (CBT) and prolonged exposure therapy (PE) for PTSD. However, the student could enhance the effectiveness of the source material by including a broader range of research studies to provide a more comprehensive view of the topic. The sources utilized are primarily from accredited scientific publications, and the student demonstrates a clear understanding of technical terms related to PTSD treatments, explaining them effectively. Furthermore, the essay includes a thorough evaluation of empirical evidence, addressing cultural, ethical, and methodological factors, while maintaining an academic tone and ensuring clarity without oversaturation of technical jargon.
