[Construction of Jung Psychological Types Scale]

Area of Science:

• Psychology
• Personality Assessment

Background:

• Carl Jung's theory of psychological types is foundational in personality psychology.
• Existing instruments may require refinement or new scales for accurate measurement.

Purpose of the Study:

• To construct and validate Jung's Psychological Types Scale (JPTS).
• To assess the reliability and validity of the newly developed JPTS.

Main Methods:

• Item generation and content validation by Jungian analysts.
• Exploratory and confirmatory factor analyses on undergraduate data.
• Reliability testing using alpha and test-retest coefficients.
• Concurrent validity assessed against the Myers-Briggs Type Indicator (MBTI) and NEO Five Factor Inventory (NEO-FFI).

Main Results:

• Factor analysis identified three orthogonal factors: extraversion-introversion (E-I), thinking-feeling (T-F), and sensation-intuition (S-N).
• The JPTS exhibited high internal consistency and test-retest reliability.
• Concurrent validity was supported by meaningful correlations with MBTI and NEO-FFI, with E-I, T-F, and S-N corresponding to Extraversion, Agreeableness (negatively), and Openness (negatively) respectively.

Conclusions:

• The JPTS is a reliable and valid instrument for measuring Jungian psychological types.
• The scale's factors demonstrate correspondence with major personality constructs like the Big Five.
• The JPTS offers a valuable tool for research and application in personality psychology.
