MMPI-2 negative treatment indicators scale and irregular discharge

Area of Science:

• Psychiatry
• Psychological Assessment
• Clinical Psychology

Background:

• The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used psychological assessment tool.
• Identifying factors associated with treatment adherence and outcomes in psychiatric inpatients is crucial for improving care.
• The MMPI-2 Negative Treatment Indicators scale (TRT) is designed to identify patients who may not benefit from or adhere to treatment.

Purpose of the Study:

• To investigate whether the MMPI-2 Negative Treatment Indicators scale (TRT) can predict irregular discharge from psychiatric inpatient treatment.
• To explore the relationship between TRT scores, K scale elevation, and treatment discharge status.

Main Methods:

• A comparative study design was employed.
• 18 psychiatric inpatients with irregular discharge were compared to 18 inpatients with regular discharge.
• The MMPI-2 Negative Treatment Indicators scale (TRT) and K scale were administered and analyzed.

Main Results:

• No statistically significant difference was found between the irregular and regular discharge groups on the MMPI-2 Negative Treatment Indicators scale (TRT).
• A significant difference was observed in K scale elevation between the two groups.
• Patients with irregular discharge showed a trend towards higher K scale elevation.

Conclusions:

• The MMPI-2 Negative Treatment Indicators scale (TRT) alone may not be a reliable predictor of irregular discharge in psychiatric inpatients.
• K scale elevation appears to be a relevant factor that may influence the interpretation of TRT scores.
• Further research is warranted to understand the interplay between K scale elevation and treatment outcomes.
