Summary
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.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
