PCN 605 Personality Disorders Case Study Presentation Guide
The speaker notes carry the marks, not the slides — and the cluster question is graded as an argument, not as a lookup.

The slides show, the notes explain
The deliverable is a presentation with speaker notes, and the notes are where the marks actually sit. Ten to fifteen slides is not much room, so slides that carry paragraphs of prose will be penalised twice — once for being unreadable as slides, and once for leaving the notes field empty when the brief asks for detailed speaker notes representing what you would say in person. Split the work deliberately: the slide carries the claim, the case detail, the criteria or the figure; the notes carry the explanation, the rationale and the citations. If you find yourself shrinking the font, the content belongs in the notes. Write the notes as spoken sentences rather than as an essay, because a marker reading them should be able to hear the presentation rather than reconstruct it from bullet points.
Six required elements across roughly a dozen slides means an allocation, not a flow. A brief description of the case, the diagnosis with its rationale, the course of treatment, the cluster identification with rationale, prognosis, and prevalence. Two of those — the diagnosis rationale and the cluster rationale — are the analytical ones and deserve more space than the descriptive four. Keep the case description genuinely brief; it is the setup, and students routinely spend four slides on it and then rush the diagnosis. Title slide and reference slide sit outside the count in most markers' reading, but check the rubric. Give each required element its own slide or pair of slides with a heading that names it, so the marker working through a rubric can find every item without hunting. Number the slides against the six required elements while you are still outlining, since a deck that reaches slide twelve with prevalence and prognosis unwritten cannot be fixed by adding two slides at the end.
The diagnostic rationale is the core and it has to be done against criteria rather than against impression. Name the disorder, then walk the actual DSM criteria and show which case details satisfy which criterion — the pattern's pervasiveness across situations, its stability and early onset, and the impairment or distress it causes. Personality disorder diagnosis has a general criteria set that applies before any specific disorder, and presentations that skip straight to the specific criteria miss the step that distinguishes a personality disorder from a state condition presenting similarly. Say what you ruled out and why. Where the case is ambiguous, say so — a slide acknowledging that two disorders in the same cluster share features and explaining how you chose between them shows more diagnostic reasoning than a confident single answer. Cite the DSM by edition and year on the rationale slide itself, because a criteria walk that does not say which manual it is walking is exactly the thing this element is testing.
The cluster question looks like a lookup and is graded as an argument, because the brief asks for the cluster *and an explanation of your rationale*. So do not simply state that the disorder sits in Cluster B. Explain what unifies that cluster — the odd or eccentric presentations of A, the dramatic, emotional or erratic presentations of B, the anxious or fearful presentations of C — and show how your case's features exemplify that grouping. This is also the natural place to acknowledge that the cluster structure is a descriptive convenience with known limitations rather than a validated taxonomy, which is the kind of point that lifts a presentation above the textbook. One sentence on the alternative dimensional models is enough to show awareness without derailing the presentation into a debate the assignment did not ask for.
Prognosis and prevalence are the two elements most likely to be filled with vague statements, and they are the easiest to make precise. Prevalence should be a figure with a source and a population attached, because community prevalence and clinical-sample prevalence differ substantially for personality disorders and quoting one as the other is a checkable error. Prognosis should distinguish the natural course from the treated course: several personality disorders show meaningful symptomatic improvement over time, which is not the same as recovery of functioning, and saying so is more accurate than either optimism or pessimism. Tie prognosis back to the treatment section, since the honest version of the prognosis slide is a statement about what changes with treatment and what tends not to. Where the disorder has a documented gender or age distribution, put it here rather than in the case description, since prevalence is the element being scored on it.
The source requirements are specific and worth reading twice: a minimum of five scholarly references, and that minimum explicitly includes your textbook and the latest DSM. So the DSM and the course text count toward five, which means three further scholarly sources — and the brief adds that they must be current. APA format is not required in the body of the slides, but sources still have to be documented, so a reference slide in APA is the safe reading. Submission goes through LopesWrite and there is a rubric to read first. Choose the three additional sources so they cover different elements — one on treatment outcome, one on prevalence, one on classification — rather than three papers about the same disorder saying the same thing. Check each source's date before counting it toward the five, because the brief asks for current references and that is the requirement most easily verified by a marker.
Required element | The version that loses marks | The version that scores |
|---|---|---|
Slide design | Paragraphs shrunk to fit | Claim on the slide, explanation in the notes |
Speaker notes | A repeat of the bullet points | What you would actually say, with citations |
Case description | Four slides of narrative | Brief setup that leaves room for the analysis |
Diagnostic rationale | Names the disorder | General criteria first, then specific criteria mapped to the case |
Differential | Absent | What was ruled out, and why |
Cluster | States A, B or C | Explains what unifies the cluster and how the case fits |
Prevalence | 'It is common' | A figure, a population and a source |
Prognosis | 'Treatment can help' | Natural course distinguished from treated course |
Sources | Five papers on the same point | DSM, textbook, and three covering different elements |

- 01Split content between slides and speaker notes according to what each is for.
- 02Justify a personality disorder diagnosis against DSM criteria, general and specific.
- 03Argue cluster membership rather than assert it.
- 04Report prevalence and prognosis with the precision each requires.
Read the full question
Review every instruction before using the planning guidance that follows.
What the presentation must contain
- 01A 10-15 slide PowerPoint presentation.
- 02A brief description of the selected case study.
- 03The diagnosis with an explanation and rationale using the latest DSM.
- 04Information on the course of treatment.
- 05The cluster identification with a rationale.
- 06Prognosis and prevalence information.

- 08A minimum of five scholarly references including the textbook and the DSM.
From the case to the prognosis
The case, briefly
Set up the presentation without consuming the deck.
The diagnosis and its rationale
Map case details to general and specific DSM criteria.
Cluster membership, argued
Explain what unifies the cluster and how the case exemplifies it.
Course of treatment
Set out the evidence-based approaches for this disorder.
Prevalence and prognosis
Give figures with populations, and distinguish natural from treated course.
Three sources beyond the DSM and the text
Recommended databases
- PubMed Central
- DSM-5-TR
- PsycINFO
- GCU library
Search sequence
- 1.Read the chosen case study against the DSM criteria first, so the research is directed at a specific disorder rather than at personality disorders in general.
- 2.Find outcome evidence for the treatment section, ideally a systematic review, because naming a therapy is not the same as showing it works for this disorder.
- 3.Search for epidemiological work giving prevalence with the population defined, since the figure is only meaningful with the sample attached.
- 4.Look for classification literature to support the cluster rationale and to supply the one sentence acknowledging the model's limitations.
Outcome, classification and long-term course
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Nothing here is cleared for citation until you have read it.
- 01
Which psychotherapy is most effective and acceptable in the treatment of adults with a (sub)clinical borderline personality disorder?
Psychological Medicine · 2023
Comparative outcome evidence for the treatment section, which lets the presentation argue for a modality rather than list the available ones.
- 02
Non-response to psychotherapy for borderline personality disorder: A systematic review
Australian and New Zealand Journal of Psychiatry · 2022
Supports an honest prognosis slide by documenting who does not respond, which is what keeps the treated-course discussion from becoming optimism.
- 03
Practical implications of ICD-11 personality disorder classifications
BMC Psychiatry · 2024
Gives the cluster rationale its wider context by setting the categorical model against the dimensional alternative now in use elsewhere.
- 04
Personality change in the Nottingham Study of Neurotic Disorder: 30-Year cohort study
Australian and New Zealand Journal of Psychiatry · 2022
Long-term follow-up evidence for the prognosis section, which is where the distinction between symptomatic improvement and functional recovery becomes demonstrable rather than asserted.
