The Altman Self-Rating Mania Scale

Area of Science:

• Psychiatry
• Psychometric Evaluation
• Mental Health Assessment

Background:

• Mania is a core symptom of bipolar disorder and other psychiatric conditions.
• Accurate self-rating scales are crucial for monitoring treatment response and disease progression.
• Existing scales may have limitations in capturing the full spectrum of manic symptoms.

Purpose of the Study:

• To develop and validate the Altman Self-Rating Mania Scale (ASRM).
• To assess the reliability and validity of the ASRM in diverse patient populations.
• To compare ASRM performance against established clinician-rated scales.

Main Methods:

• The ASRM was administered to patients with schizophrenia, schizoaffective disorder, depression, and mania.
• Concurrent validity was assessed using the Clinician-Administered Rating Scale for Mania (CARS-M) and Mania Rating Scale (MRS).
• Test-retest reliability was evaluated in depressed and manic patient subgroups.

Main Results:

• Principal components analysis identified three factors: mania, psychotic symptoms, and irritability.
• Manic patients exhibited significantly higher baseline mania scores than other groups.
• The ASRM demonstrated significant correlations with MRS (r = .718) and CARS-M (r = .766) scores.
• High sensitivity (85.5%) and specificity (87.3%) were achieved for mania subscale scores > 5.

Conclusions:

• The Altman Self-Rating Mania Scale (ASRM) is a psychometrically sound instrument for self-assessment of mania.
• The ASRM shows good reliability and validity, comparable to clinician-rated measures.
• The scale offers advantages for patient self-monitoring and clinical assessment of manic symptoms.
