Do you think I need to study ALL the diagnosis for the DM5 for the national board exam of MFT?

Hi there,

I am studying for the MN National Board Exam for LMFT. I am currently studying the DSM-5 TR for the all the diagnosis. I am needing clarification and understanding about the criteria for Delusional Disorder (F22) for the following:

Criterion B: (Criterion A for schizophrenia has never been met. Note: hallucinations, if present, are not prominent and are related to the delusional theme). (e.g., the sensation of being infested with insects associated with delusions of infestation).
Criterion C: Apart from the impact of the delusion(s) or it ramifications, functioning is not markedly impaired, and behavior is not obliviously bizarre or odd.

I am not sure what those mean and if someone could clarify those for me that would be greatly appreciated!

A therapist is working with a family in which a child has recently begun exhibiting behavioral problems at school. During sessions, the therapist observes that whenever the parents attempt to address ongoing marital conflict, the child’s symptoms intensify, shifting attention away from the couple’s issues. From a systemic perspective, the child’s behavior is BEST understood as:

a. A sign of unresolved individual pathology within the child that requires individual treatment
b. An attempt by the child to gain attention and control within the family system
c. A homeostatic mechanism that functions to stabilize the family by diverting attention from marital conflict
d. Evidence that the parents lack effective behavioral management strategies for the child

Homeostasis refers to a system’s natural tendency to maintain stability and resist change, even when the pattern is unhealthy. In family systems, behaviors (including symptoms) often serve a function that keeps the system balanced. When one part of the system tries to change, other members may (consciously or unconsciously) respond in ways that pull the system back to its usual pattern. This is why progress can feel “stuck” or why symptoms may reappear—because the system is trying to restore its familiar equilibrium.

Key Points to Memorize

• Systems prefer stability over change

• Symptoms often have a purpose (maintain balance)

• Change in one member → reaction from others

• Dysfunction can still feel “normal” to the system

• Resistance = system trying to return to homeostasis

Exam Clues

• “Every time things improve, the problem returns”

• “One member improves → another worsens”

• “Behavior distracts from deeper issue (e.g., marital conflict)”

Quick Example

• Child acts out → parents focus on child → avoid marital conflict
  Symptom = maintains homeostasis

Most often, we miss questions due to falling into predictable traps, not lacking content knowledge. Below are some common traps that can get us in trouble...

1. Acting Too Quickly (Skipping Assessment)

Trap: Jumping straight into intervention (CBT, referrals, advice)

Why it’s wrong: You must understand the problem first.

What they want instead:

• Clarify

• Gather more information

• Assess risk, context, and functioning

Reframe: “Do I fully understand what’s going on yet?”
If not → ASSESS is the correct answer

2. Ignoring Safety Cues

Trap: Missing subtle risk indicators in the vignette

Examples they sneak in:

• “Client has access to pills”

• “States they feel like a burden”

• “History of attempts”

• “Child left alone frequently”

Why it’s wrong: Safety always overrides all other interventions.

Correct move:

• Suicide/homicide assessment

• Reporting if mandated

• Safety planning or hospitalization if needed

Reframe: “Is there ANY risk here, even indirectly?”

3. Over-Diagnosing / Labeling Too Soon

Trap: Choosing answers that assign a diagnosis too early

Why it’s wrong: The exam values assessment before diagnosis and avoids premature labeling.

Correct approach:

• Focus on symptoms and context

• Rule out situational factors (grief, trauma, culture)

Reframe: “Do I have enough info to diagnose—or should I assess more?”

4. Choosing Extreme or Rigid Answers

Trap answers often include:

• “Immediately terminate”

• “Report right away” (without enough evidence)

• “Confront the client directly”

• “Tell the client…”

Why it’s wrong: The exam often favors least restrictive, least intrusive interventions first.

Correct answers tend to:

• Be collaborative

• Be gradual

• Preserve rapport

Reframe: “Is this the least extreme appropriate action?”

5. Ignoring Cultural & Contextual Factors

Trap: Treating all clients the same without context

Missed cues include:

• Cultural stigma

• Immigration status

• Religion

• LGBTQ+ identity

• Socioeconomic stressors

Why it’s wrong:
The exam is heavily systemically focused.

Correct answers:

• Show cultural humility

• Explore meaning

• Avoid assumptions

Reframe: “What context am I missing?”

6. Breaking Confidentiality Incorrectly

Trap: Either:

• Breaking confidentiality too quickly
  OR

• Failing to break it when required

Know the balance:

• Break ONLY when legally required (danger, abuse, court order)

• Otherwise → protect confidentiality

Reframe: “Is there a legal/ethical requirement—or just concern?”

7. Picking the “Best Sounding Therapy” Instead of Process

Trap: Choosing modalities (CBT, DBT, MI) just because they sound correct

Why it’s wrong:
The exam tests process over technique

Correct answers often:

• Reflect empathy

• Clarify client experience

• Build alliance first

Reframe: “Do I need a technique yet—or understanding?”

8. Ignoring the Question Stem (FIRST vs BEST vs NEXT)

Trap: Answering the wrong question type

• FIRST = assessment

• NEXT = step after assessment

• BEST = most complete/appropriate overall

Why it’s wrong: You might pick a correct action—but at the wrong time.

Reframe: “Where am I in the clinical process?”

9. Not Thinking Systemically

Trap: Focusing only on the individual

Missed areas:

• Family dynamics

• Environment

• Relationships

• Systems impact

Correct answers:

• Include broader context

• Consider supports and stressors

Reframe: “Who/what else is influencing this situation?”
