Summary
A new self-report tool, the Nightmare Disorder Index (NDI), shows that many nurses experience nightmares and probable nightmare disorder, impacting their psychosocial functioning. Screening is recommended for this high-risk group.
Area of Science:
- Psychiatry
- Sleep Medicine
- Nursing Health
Background:
- Nurses are a high-risk group for nightmares.
- Limited data exists on nightmare disorder prevalence and psychosocial factors in nurses.
- A validated self-report measure for nightmare disorder was lacking.
Purpose of the Study:
- Develop and validate a self-report measure for DSM-5 nightmare disorder.
- Assess the prevalence of nightmare disorder among nurses.
- Examine psychosocial factors associated with nightmare disorder in nurses.
Main Methods:
- Developed the Nightmare Disorder Index (NDI) for self-report.
- Administered NDI, psychosocial, and demographic questionnaires to 460 nurses.
- Utilized sleep diaries and actigraphy for a subset of 400 nurses.
Main Results:
- The NDI demonstrated good psychometric properties (internal consistency α = 0.80).
- 7.4% of nurses met full criteria for probable nightmare disorder, with 43.9% meeting partial criteria.
- Nurses with nightmare disorder showed significantly poorer psychosocial functioning (PTSD, depression, anxiety, stress).
Conclusions:
- The NDI is an efficient and valid self-report tool for nightmare disorder.
- High rates of nightmares and nightmare disorder are prevalent in nurses.
- Nightmare disorder is linked to poorer psychosocial functioning, warranting increased screening in healthcare workers.

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

01:29Nursing Interventions II: Selecting and Classifying the Nursing Interventions
2.9K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.

A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...
