Abstract

Insights

The Persian version of the Mood Disorder Insight Scale (MDIS) is a reliable tool for assessing insight in bipolar I disorder patients. This validated scale aids in understanding patient awareness, crucial for treatment adherence and outcomes.

Area of Science:

  • Psychiatry
  • Psychological Assessment

Background:

  • Impaired insight in bipolar I disorder correlates with poor prognosis and treatment adherence.
  • Specialized scales are needed to accurately evaluate insight in these patients.
  • The Mood Disorder Insight Scale (MDIS) is a potential tool for this assessment.

Purpose of the Study:

  • To evaluate the validity and reliability of the Persian version of the Mood Disorder Insight Scale (MDIS).

Main Methods:

  • 145 bipolar I disorder patients from Iran Hospital of Psychiatry participated.
  • Patients completed the Persian MDIS after undergoing the Persian Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and the Scale to Assess Unawareness of Mental Disorder (SUMD).

Main Results:

  • The Persian MDIS demonstrated satisfactory internal consistency (Cronbach's alpha = 0.8).
  • Excellent test-retest reliability was observed (0.95, p < 0.01).
  • Factor analysis and correlation with SUMD (0.85) supported construct and concurrent validity.

Conclusions:

  • The Persian version of the MDIS is a valid and reliable instrument.
  • It can be effectively used for assessing insight in individuals with bipolar I disorder.

One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
