The validity of the California Q-set Alexithymia Prototype

Area of Science:

• Psychology
• Clinical Psychology
• Personality Psychology

Background:

• Alexithymia is a personality construct characterized by difficulties identifying and expressing emotions.
• Validating measurement tools for alexithymia is crucial for accurate psychological assessment.

Purpose of the Study:

• To examine the validity of the California Q-set Alexithymia Prototype (CAQ-AP) as both an observer and self-report measure.
• To assess the CAQ-AP's reliability in capturing the alexithymia construct.

Main Methods:

• The study involved 155 undergraduate college students.
• Observer-based alexithymia similarity scores from the CAQ-AP were correlated with scores on established self-report scales for relevant psychological constructs.

Main Results:

• Alexithymia scores demonstrated statistically significant positive correlations with neuroticism, depression, and anxiety.
• Conversely, alexithymia showed significant negative correlations with extraversion, openness, and emotional expression.
• These findings align with theoretical expectations for the alexithymia construct.

Conclusions:

• The California Q-set Alexithymia Prototype (CAQ-AP) has successfully passed a second validity check.
• The CAQ-AP is recommended as a reliable observer-based measure for assessing the alexithymia construct in psychological research.
