## 문제

A nurse is assessing a 35-year-old client who reports persistent fatigue and pain for the past 6 months. Which assessment finding would be most characteristic of illness anxiety disorder?

## 보기

1. The client expresses relief when told that medical tests are normal and symptoms are likely stress-related
2. The client continues to seek multiple medical opinions and remains convinced that a serious medical condition exists **✔ 정답**
3. The client acknowledges that stress may be contributing to the physical symptoms and is willing to consider psychological interventions
4. The client's symptoms completely resolve when distracted by engaging activities or social interactions

**정답: 2**

## 해설

Illness anxiety disorder involves persistent preoccupation with having a serious illness despite normal tests, and seeking multiple medical opinions, as in option 2. Other options (relief with normal results, stress acknowledgment, symptom resolution with distraction) are not characteristic.

Understanding the Core Feature of Illness Anxiety Disorder

This question targets a critical distinction in psychiatric nursing: differentiating illness anxiety disorder (IAD) from other conditions involving physical symptoms, such as somatic symptom disorder (SSD). The key to answering correctly lies in understanding the cognitive and behavioral response to health information, not just the presence of symptoms.

In IAD, the central feature is a persistent preoccupation with having or acquiring a serious illness. According to the provided research by Kikas et al. (2026), which directly compares IAD and SSD in health-anxious individuals, the diagnostic criteria for IAD specify that somatic symptoms, if present, are only mild in intensity [1]. The driving force is the high level of health anxiety itself. When a client with IAD is presented with normal test results or medical reassurance, the anxiety does not abate. Instead, they often doubt the findings, fear a missed diagnosis, or believe the tests were inadequate. This leads to a characteristic pattern of "doctor shopping" and repeated requests for medical investigations.

Analysis of the Correct Answer

Option 2 is correct because it captures this defining behavioral pattern: the client continues to seek multiple medical opinions and remains convinced that a serious medical condition exists, despite evidence to the contrary. This demonstrates the core cognitive distortion of IAD—a fixed, false belief of being sick that is resistant to medical reassurance. The study's focus on comparing IAD with and without moderate-to-severe somatic symptoms underscores that the hallmark of IAD is the illness preoccupation itself, which persists regardless of the severity of any concurrent physical symptoms [1].

Why the Other Options Are Incorrect

-   Option 1: Expressing relief when told tests are normal is a healthy, adaptive response. This directly contradicts the persistent health anxiety and non-reassurability that defines IAD. A client with IAD would not feel relief from normal results.

-   Option 3: Acknowledging a mind-body connection and showing willingness to consider psychological interventions indicates good insight and is more characteristic of someone who is not pathologically fixated on a disease-based explanation. This openness is the opposite of the rigid, somatic attribution seen in IAD.

-   Option 4: Symptoms that completely resolve with distraction are a hallmark of conversion disorder (functional neurological symptom disorder) or, in some contexts, a feature of factitious disorder, where secondary gain is prominent. This phenomenon, sometimes called "la belle indifférence," is not characteristic of IAD, where the distress and preoccupation are pervasive and not easily dismissed.

Clinical Reasoning and NCLEX Application

From an NCLEX-RN perspective, the assessment of a client with persistent fatigue and pain requires the nurse to look beyond the symptoms to the client's cognitive and emotional response. The critical nursing assessment for suspected IAD is the client's reaction to medical reassurance. A response of continued fear, skepticism, and further help-seeking behavior, as described in option 2, is the most specific and characteristic finding. The research by Kikas et al. (2026) supports this by highlighting that the minimal somatic symptom requirement in the current IAD diagnosis is designed to isolate this core feature of illness preoccupation without the confounding factor of significant somatic distress that defines SSD [1]. Therefore, when a nurse observes a pattern of non-reassurable health anxiety and repeated medical consultations in a client with mild or absent physical findings, IAD should be a primary consideration.References (research sources)

## 임상 시나리오

Clinical Guide: Illness Anxiety DisorderKey Assessment and Intervention Strategies
The hallmark of Illness Anxiety Disorder is a persistent preoccupation with having a serious illness, despite normal medical evaluations. Somatic symptoms are either absent or mild.

A defining behavioral pattern is doctor shopping, where the client seeks multiple medical opinions after receiving reassurance. This stems from a core cognitive distortion—a fixed belief that a serious condition has been missed.

Nursing AlertDo not challenge the client's belief directly. Acknowledge their distress without reinforcing the illness conviction. Schedule regular, brief follow-ups to build trust and gradually shift focus to coping strategies.

## 핵심 개념

- **Illness Anxiety Disorder** — A psychiatric condition characterized by persistent preoccupation with having or acquiring a serious illness, with mild or absent somatic symptoms, and high health anxiety that is not relieved by medical reassurance.
- **Somatic Symptom Disorder** — A disorder characterized by one or more distressing somatic symptoms that disrupt daily life, accompanied by excessive thoughts, feelings, or behaviors related to the symptoms.
- **Doctor Shopping** — A behavioral pattern where a patient consults multiple healthcare providers for the same issue, often due to dissatisfaction with previous diagnoses or reassurance, commonly seen in Illness Anxiety Disorder.
- **Health Anxiety** — Excessive worry about having or developing a serious medical condition, which persists despite appropriate medical evaluation and reassurance.
- **Cognitive Distortion** — Inaccurate or exaggerated thought patterns, such as the fixed false belief of being sick in Illness Anxiety Disorder, that contribute to maladaptive behaviors and emotional distress.
