The Clinical Anger Scale: preliminary reliability and validity

Area of Science:

• Psychology
• Clinical Psychology
• Psychometrics

Background:

• Clinical anger is a significant issue in mental health.
• Objective measurement tools for clinical anger are needed.
• Existing measures may have limitations in scope or validity.

Purpose of the Study:

• To develop and validate the Clinical Anger Scale (CAS).
• To assess the psychometric properties of the CAS.
• To explore the relationship between clinical anger and other psychological constructs.

Main Methods:

• Development of the Clinical Anger Scale (CAS) as an objective self-report instrument.
• Factor analysis to confirm the CAS's item structure.
• Reliability analyses (internal consistency, test-retest stability).
• Correlational analyses to assess relationships with other variables (social desirability, anger constructs, psychopathology, personality, family environment).

Main Results:

• The CAS demonstrated a unidimensional item structure.
• The CAS showed adequate internal consistency and test-retest stability.
• The CAS was not influenced by social desirability.
• Clinical anger, as measured by the CAS, positively correlated with trait anger, state anger, anger-in, anger-out, and anger-control.
• The CAS showed predictable relationships with psychopathological symptoms, personality traits, and early family environments.

Conclusions:

• The Clinical Anger Scale (CAS) is a promising, validated instrument for measuring clinical anger.
• The CAS possesses good psychometric properties, including reliability and validity.
• The CAS can be a valuable tool for future research and clinical assessment of anger.
