IB Psychology SL Extended Essay Example

The research question is clearly stated and tightly anchored to a specific treatment and condition. Framing the task around “to what extent” gives the essay room for balanced judgement rather than a simple yes/no answer, which is a strong starting point for focused investigation.

The sectioning is logical and reader-friendly: the essay moves from background to treatment overview, then into evidence, comparison, and limitations. This helps the argument unfold in a controlled way and supports the research focus.

What would count as “most successful” in this essay: symptom reduction, long-term relapse prevention, cost, accessibility, or patient preference? Clarifying that decision early would help the student evaluate evidence consistently rather than shifting between criteria later on.

Consider naming the main source types and how they will be selected, for example systematic reviews, clinical guidelines, and primary studies. A brief method statement with search terms or inclusion criteria would make the research process much more transparent and credible.

The focus begins to drift here: the essay promises to examine “validity,” “reliability,” “effectiveness,” and “current level of success,” which are related but not identical. The student should define which criterion will actually be used to judge EMDR so the investigation stays controlled and the conclusion is easier to defend.

This widens the purpose beyond the research question and introduces an unsupported ethical claim about antidepressants. The student should keep the introduction tied to EMDR for PTSD and avoid speculative statements unless they are later justified with evidence.

This is a factual statement, but it is used as if historical development alone strengthens the method. The student should explain why this timeline matters for the research question, or else keep the development section shorter so it does not distract from evaluating effectiveness.

The student shows secure understanding of PTSD as a persistent condition with functional consequences, not just a short-term reaction. Linking symptoms, duration, and treatment need demonstrates good conceptual awareness and supports the later comparison of therapies.

This oversimplifies antidepressants and risks misleading the reader. The student should distinguish between medication classes, symptom management, and the limits of pharmacological treatment for PTSD rather than reducing the concept to a single broad function.

The student uses an important concept, but the explanation is too absolute. AIP should be presented as the theoretical model underlying EMDR, not as a proven description of how all trauma is stored in the brain. More careful wording would improve accuracy.

The student demonstrates good source application here by connecting the evidence base to real comparative treatments. This shows understanding of how EMDR is evaluated in relation to alternatives rather than in isolation.

The explanation of clinical significance is incomplete. The student should finish the distinction clearly and explain why a statistically significant result may still have limited real-world value if the change does not meaningfully improve symptoms or functioning.

A single case example can illustrate treatment, but it cannot establish general effectiveness. The student should separate anecdotal evidence from research evidence and avoid using one testimonial-style case to support a broad conclusion about EMDR.

Consider clarifying whether this claim refers to equivalence, no significant difference, or simply insufficient evidence. A more precise distinction would show stronger command of the terminology and help the comparison sound more academically careful.

This is an important evaluative claim, but it needs sharper support. The student should explain why evidence is weaker in these groups and whether the limitation comes from sample size, trauma complexity, or inconsistent outcomes rather than just stating that it “decreases.”

The student begins to evaluate methodology rather than just summarise findings. Recognising the role of randomisation and bias reduction shows real analytical thinking and helps justify why the evidence is taken seriously.

This is a good starting point, but the criticism stays too general. The student should explain which drawback matters most for this topic, such as sample representativeness, outcome measures, follow-up duration, or comparison groups, and then link that directly to EMDR.

The conclusion reads too strongly for a case study and sounds more certain than the evidence allows. The student should avoid turning an individual example into proof and instead treat it as a brief illustration that sits alongside broader research findings.

The student does not ignore limitations; they try to extend the discussion to more complex trauma presentations. That broader perspective is useful because it prevents the essay from treating all PTSD cases as identical.

This sentence moves from a general side-effect claim to a specific conclusion about EMDR outcomes without enough evidence. The student should either support the interaction between medication and EMDR with stronger research or present this more cautiously as a possibility rather than a settled effect.

The student makes a strong claim from a source without showing enough analysis of the study’s design or limits. To strengthen this, the essay should explain what outcome improved, for whom, and whether the evidence supports combination therapy generally or only under specific conditions.

This shows the student is attempting comparison rather than one-sided praise. Bringing in relative outcomes is useful because it moves the essay toward evaluative judgement instead of simple description.

The explanation here is speculative and not academically precise. The student should replace this with a clearer evidence-based reason for caution, such as increased cognitive load, conflicting therapeutic aims, or lack of supporting research.

This comparison loses focus on PTSD because neuromodulation is discussed mainly in relation to depression. The student should explain why this treatment is relevant to the research question, or replace it with a more directly comparable PTSD intervention so the discussion stays tightly targeted.

How would this judgement change if the student defined “benefits” more narrowly, for example by focusing only on symptom reduction rather than general quality of life? A clearer evaluative criterion would make the cost discussion more convincing.

The conclusion is positive, but it is not fully balanced by the evidence developed earlier. The student should synthesise the strongest supporting and limiting evidence, then state a more qualified final judgement about which PTSD populations and outcomes justify calling EMDR “valid.”

The table of contents is useful, but several entries appear duplicated or unevenly aligned, which makes the structure harder to scan. The student should ensure each major section appears once and that page references match the final organisation of the report.

The report includes a clear contents page, which improves navigation and shows a logical organisation of sections. This helps the reader anticipate the argument and find evidence quickly.

The referencing style is inconsistent here, with duplicated bracketed information and unclear author/title separation. The student should standardise citations so each source is easy to identify and trace back to the bibliography.

The bibliography is present and the essay includes a wide range of source entries. That gives the report a recognizable academic structure and shows that the student attempted to document research thoroughly.

The access date is written incorrectly as “22th,” which weakens the professionalism of the presentation. The student should proofread all bibliography entries carefully so dates, punctuation, and capitalisation are consistent.

This entry shows that citation formatting is not fully consistent across the bibliography, especially in title capitalisation and journal presentation. A single referencing system should be followed throughout so the source list looks coherent and academically reliable.

Consider making the bibliography entries more uniform by adding the missing publication details in the same style as the other academic sources. Consistency here would make the research trail easier to follow and strengthen the overall professionalism of the report.
