PMH/503 Week 2: Case Formulation and Treatment Planning, sample paper

Reviewed by Lenora Whitcombe, MSN, RN · University of Phoenix

This page holds a complete PMH/503 Week 2 sample paper on case formulation and treatment planning, in true APA form. A 50-year-old engineer laid off after 25 years presents with depression and anger. A psychiatric nurse practitioner student builds a formulation of predisposing, precipitating, perpetuating and protective factors, explains why formulation adds to diagnosis, addresses reliability concerns from research and derives a treatment plan with measurable goals.

Mr. W., a 50-year-old mechanical engineer, was laid off four months ago after 25 years with the same company. He now meets criteria for major depressive disorder, with a PHQ-9 of 17, and his wife says he snaps at her and their teenage children. He says, "I built half their products, and they threw me out like trash." This paper develops a case formulation and the treatment plan that follows from it.

Why Formulation

Macneil et al. (2012) argue that diagnosis alone is often insufficient to guide intervention in mental health, and that case formulation, an individualized explanation of the person's difficulties, links assessment to treatment by identifying the mechanisms to target. Two people with the same diagnosis may need different treatments because different factors drive and maintain their problems.

Building It Together

I explain the four Ps and invite Mr. W. to build the formulation with me on a whiteboard. Collaboration increases its accuracy and his investment in it.

Predisposing Factors

Mr. W. grew up with a father who valued achievement and rarely praised him. He learned that his worth depended on performance. He has a family history of depression in his mother. His identity has been tied almost entirely to his work.

Precipitating Factor

The layoff, delivered in a five-minute meeting with no acknowledgment of his contributions, struck at his core belief that he is valuable only if he is productive.

Perpetuating Factors

Since the layoff, he has stopped seeing former colleagues out of shame, stays home and ruminates, sleeps late and drinks three beers nightly. Each behavior reduces opportunities for success and connection and keeps him focused on loss. His thoughts, "I'm worthless now," "No one will hire someone my age," fuel both depression and anger. His irritability pushes his family away, confirming his sense of being unwanted.

Protective Factors

He has a supportive wife, good problem-solving skills, financial severance for six months, a friend from college who calls weekly and a history of coping well with past challenges.

The formulation shows that the layoff did not cause his depression by itself; it collided with a lifelong rule that his worth is his work.

What this part is doingEach of the four Ps is filled with specific details from the client, which is what makes the formulation useful for treatment.

Is Formulation Reliable?

Kuyken et al. (2005) studied the reliability and quality of cognitive case formulations and found that clinicians agreed reasonably well on descriptive elements, such as the presenting problems and precipitants, but less well on inferred mechanisms, such as underlying beliefs, and that quality varied with clinician training. This suggests that formulations should stay close to evidence, be tested with the client and be revised as new information emerges.

From Formulation to Plan

Each perpetuating factor becomes a target. Withdrawal and inactivity point to behavioral activation: scheduling activities that bring mastery and pleasure, including reconnecting with colleagues. Negative thoughts point to cognitive restructuring: examining the evidence for "I'm worthless" and developing balanced alternatives. Alcohol use points to monitoring and reduction. Irritability points to recognizing anger triggers and communicating needs to his family. The predisposing belief that worth equals productivity becomes a longer-term target for exploring a broader sense of identity.

Cultural and Developmental Context

At 50, Mr. W. faces age-related barriers in the job market that are real, not only distorted thoughts. The formulation must distinguish accurate appraisals from exaggerated ones. His belief that "no one will hire someone my age" contains a truth about discrimination and a distortion in its absoluteness. Cognitive work will not deny the barrier but test the "no one."

Family System

His irritability affects his wife and children, and their responses, withdrawing or arguing, affect him. Including his wife in one session to share the formulation can help her understand his anger as part of depression and help the family respond in ways that reduce conflict.

Risk Assessment

Middle-aged men who lose employment and drink are at increased risk of suicide. I ask directly about suicidal thoughts, which he denies, and about firearms in the home; he has a hunting rifle, and we discuss storing it with a friend during this period. The formulation includes risk as a perpetuating and potentially dangerous factor.

Strengths as Tools

Protective factors are not only buffers but tools. His engineering problem-solving skills can be applied to the job search as a project with steps, and his friend's weekly calls can become planned activities rather than passive support.

Collaborative Language

I write the formulation in his words where possible, such as "thrown out like trash" beside "loss of role and respect," so that it feels like his story rather than a clinical label.

Anticipating Obstacles

The formulation also predicts obstacles. His belief that he must perform well may make homework feel like a test he can fail. I plan to frame early assignments as experiments, where any result teaches us something, reducing the risk that he avoids them. His drinking may blunt motivation in the evenings, so activities are scheduled earlier in the day.

Medication

Given moderate-to-severe symptoms, I discuss adding an antidepressant alongside therapy; he prefers to start with therapy and revisit in four weeks, which is reasonable with close monitoring.

Sharing the Formulation With Him

When we finished, Mr. W. looked at the whiteboard and said, "So it's not just that I'm weak." Seeing his difficulties as understandable responses to a real loss, shaped by old rules, reduced his shame and increased his willingness to try the plan.

Revisiting After Six Weeks

If his mood improves with activation but anger persists, the formulation suggests shifting focus to family communication; if mood does not improve, it suggests revisiting the core belief work or adding medication.

Wife's Perspective

His wife, in a joint session, adds that he now spends hours at the computer reading about layoffs, a form of rumination we add to the formulation.

Measurable Goals

Goals are specific and measurable: reduce PHQ-9 below 10 in 12 weeks; contact two former colleagues within four weeks; limit drinking to two nights a week; hold a weekly family dinner without arguments; complete three job applications or informational interviews a month.

Choice of Therapy

The formulation points to cognitive behavioral therapy as the primary approach, with behavioral activation first, since activation often improves mood before cognitive work. Wampold (2015) reminds that the alliance and a coherent rationale matter across approaches; sharing the formulation provides that rationale.

Review

We will review the formulation at week six to test whether it still fits and revise it with any new information.

Conclusion

Mr. W.'s depression and anger are explained by a lifelong belief tying worth to work, precipitated by an abrupt layoff and maintained by withdrawal, rumination, drinking and irritability, with a supportive family and past resilience as strengths. Built with him and kept close to evidence, as reliability research advises, the formulation produced a plan of behavioral activation, cognitive work, alcohol reduction and family communication, each linked to a measurable goal.

How this PMH 503 Week 2 example is structured

The PMH/503 Week 2 work usually covers case formulation and treatment planning. This paper shows a formulation built step by step with the client and then shows how each part points to a specific treatment target. Students search this week as PMH 503 Week 2, PMH503 Wk 2 or PMH/503 Wk 2; all three are the same assignment.

PMH/503 Week 2 questions, answered

What does PMH/503 Week 2 usually ask for?

Many sections ask students to develop a case formulation and a treatment plan that links the formulation to interventions and goals.

What are the four Ps of formulation?

Predisposing factors that create vulnerability, precipitating factors that triggered the problem, perpetuating factors that maintain it and protective factors that support recovery.

Why use a formulation if there is already a diagnosis?

A diagnosis names the disorder; a formulation explains why this person has these problems now and what keeps them going, which guides individualized treatment.
