Application of the problem-solving model: case guide
An 11-12 slide case presentation that pairs a problem-solving blueprint with a theoretical orientation — and where seven of the nine required points repeat the same instruction to keep the theory in view.

What does 'the problem-solving model AND a theory' actually require?
The instruction that shapes every slide is the capitalised **AND**: you use the problem-solving model *and* a theory. Those are not the same kind of thing and the assignment depends on you knowing it. The problem-solving model is a **blueprint** — D'Zurilla's steps of problem definition and formulation, generation of alternatives, decision making, and solution implementation and verification. A theoretical orientation is what explains *why* the client's problem takes the form it does and what will shift it. The model gives you the sequence; the theory fills each step with content. Seven of the nine required bullets end with a variant of *keep the theoretical orientation in mind*, which is the brief telling you the same thing seven times. Say on your second slide which theory you have chosen and why it suits this client, so the pairing is established before the steps begin.
That repetition is the grading criterion in disguise, so make the theory visible at every step rather than naming it once on slide two. Concretely: if you choose a cognitive-behavioural orientation, assessment of problem orientation looks at the client's appraisals and beliefs about the problem; if you choose systems or family theory, it looks at how the problem is defined and maintained within relationships; if you choose crisis theory, it looks at how the event has overwhelmed usual coping. The same is true at solution generation and implementation. A presentation where the theory could be swapped for any other without changing a single slide has not met the requirement the brief keeps restating. A quick self-test before submitting: cover the theory's name on every slide and ask whether a reader could still identify it from the content.
The second bullet asks how you would assess the client's **problem orientation** — how the client perceives the problem — and this is far more important than its position in the list suggests. Problem orientation is not a warm-up before the real work: component analyses of problem-solving therapy find that treatment is more effective when it includes training in a **positive problem orientation** rather than problem-solving skills alone, and when all four of D'Zurilla's core skills are covered. So a client who believes the problem is unsolvable or that they are incapable of solving it needs that addressed first, and you can say so on evidence rather than as an opinion. That single point will lift the assessment slides above description. It also gives the assessment slide something to recommend, rather than only something to report.
Two of the final bullets are evaluative and they are the ones most often turned into praise. *Evaluate how well the problem-solving model can be used for short-term treatment of this client* and *evaluate one merit and one limitation* both require a judgement with something on the other side. The evidence supports a genuinely balanced answer: problem-solving therapy performs comparably to other psychosocial therapies and to medication for depression and better than no treatment, and a meta-analysis in older adults found a significant reduction in depressive symptoms and in functional disability. But the youth literature is weaker — the trial at lowest risk of bias found improvements in solving personal problems without a significant effect on emotional symptoms. Match the evidence you cite to your client. Citing evidence from the wrong population without flagging it is the commonest way this evaluation goes wrong.
Finally, treat the format as a constraint on content rather than as packaging. Eleven to twelve slides for nine required content points leaves roughly one slide each plus a title and reference slide, so there is no room for a background section on the model's history or a biography of Helen Perlman. Put one bullet's answer on each slide, name the case (the Jake Levy case study you selected in Week 2) once and then work from it rather than re-describing it, and use the speaker notes for the reasoning that will not fit on the slide. Note also that the brief's own list of presentation guidelines is cut off in the source, so check your course page for the formatting requirements that should follow. Speaker notes are also where the marker looks for the reasoning that a bulleted slide cannot carry, so do not leave them empty.
Required point | What the theory must do there | The slide that fails |
|---|---|---|
Theoretical orientation identified | Named, and chosen for a reason | Named and never used again |
Assess problem orientation | Theory-specific view of how the client sees the problem | A generic statement that the client feels stuck |
Problem definition and formulation | Formulated in the theory's own terms | A restatement of the presenting problem |
Two solutions | At least one arising from the theory | Two generic interventions |
Implementation and mobilisation | How this client, in this theory, can act | A plan with no client in it |
Evaluate outcome / short-term fit / merit and limitation | A judgement with evidence on both sides | Praise for the model |
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Distinguish a practice model from a theoretical orientation and use both together.
- 02Apply a chosen theory consistently across every stage of a case formulation.
- 03Treat problem orientation as an active treatment target rather than a preliminary.
- 04Evaluate a practice model against evidence rather than endorsing it.
Read the full question
Review every instruction before using the planning guidance that follows.
What the 11-12 slides have to cover
- 01An 11- to 12-slide PowerPoint presentation.
- 02The selected theoretical orientation, identified.
- 03An assessment of the client's problem orientation, informed by that theory.
- 04Problem definition and formulation in the theory's terms.
- 05Two possible solutions, at least one arising from the theory.
- 06Implementation, the client's capacity to mobilise it, and outcome evaluation.
- 07An evaluation of short-term fit, plus one merit and one limitation.
From problem orientation to merit and limitation
Orientation and case framing
Name the theoretical orientation, say why it was chosen, and identify the case.
Assessing problem orientation
Establish how the client perceives the problem, through the theory's lens.
Problem definition and formulation
Formulate the problem in the theory's own vocabulary.
Solutions, implementation and mobilisation
Generate two solutions, implement one, and assess the client's capacity to act.
Evaluation, fit, merit and limitation
Define how outcome would be judged, then evaluate the model itself for this case.
Reading the case before reading the model
Recommended databases
- The course textbook, D'Zurilla's five steps
- The assigned Westefeld and Heckman-Stone (2003) article
- PubMed and PubMed Central
- Social Work Abstracts and PsycINFO
Search sequence
- 1.Reread the case study before anything else, since every one of the nine points is about this client and a presentation built from the model outward will not fit them.
- 2.Read the assigned Westefeld and Heckman-Stone article for the worked example the brief points at — it shows a theory being layered onto the problem-solving blueprint, which is exactly the move you are being asked to make.
- 3.Search problem-solving therapy outcome evidence for your client's population, because the two evaluative points need evidence and it differs by age group.
- 4.Look up how your chosen theoretical orientation conceptualises assessment specifically, so the problem-orientation slide is theory-specific rather than generic.

Efficacy of problem-solving therapy in treating late-life depression with potential cognitive impairment: a systematic review and meta-analysis
BMJ Open · 2024
Current evidence on where problem-solving therapy fits, useful for the short-term-treatment evaluation: it is described as a practical approach focused on resolving issues and taking action, with evidence that it may improve depressive symptoms and executive function together. Note that the brief's own assigned reading, Westefeld and Heckman-Stone (2003) in The Counseling Psychologist, sits behind a publisher bot wall and should be retrieved through your university library rather than the open web.

Meta-analysis of problem solving therapy for the treatment of major depressive disorder in older adults
International Journal of Geriatric Psychiatry — Kirkham, Choi and Seitz · 2016
Evidence for the merit side of your evaluation: across nine randomised trials and 569 participants, problem-solving therapy produced a significant reduction in depressive symptoms and in functional disability. Cite it if your client is an older adult; note its population if they are not, since transferring the finding without saying so is the error this evaluation invites.

Problem-solving training as an active ingredient of treatment for youth depression: a scoping review and exploratory meta-analysis
BMC Psychiatry · 2021
The limitation side, and a genuinely balanced one: for young people, the trial at lowest risk of bias found problem-solving training helped with solving personal problems but did not significantly reduce emotional symptoms. Using this alongside the older-adult meta-analysis lets you argue that the model's effectiveness is population-dependent, which is a stronger limitation than a generic caveat.
Before the presentation is submitted
Common mistakes
- Treating the problem-solving model and the theory as alternatives rather than a blueprint plus content.
- Naming the theoretical orientation once and never applying it again.
- Producing slides where the theory could be swapped out without changing anything.
- Treating problem orientation as a warm-up rather than as an active target.
- Offering two generic solutions with no link to the chosen theory.
- Describing implementation with no reference to this client's capacity to act.
- Turning the two evaluative points into praise for the model.
- Spending slides on the model's history instead of on the nine required points.
Submission checklist
- The presentation is 11 to 12 slides.
- All nine required points are addressed, one per slide where possible.
- The theoretical orientation is named early and visible in every subsequent slide.
- Problem orientation is assessed in the theory's own terms.
- At least one of the two solutions stems from the theory.
- The client's capacity to mobilise the solution is addressed specifically.
- Short-term fit, one merit and one limitation are each argued with evidence.
- The case is named once and then worked from, not re-described.
