Iconographic Professional Interests Inventory (3IP): A New Validation Study

Area of Science:

• Psychology
• Career Development

Background:

• Vocational interests are crucial in career counselling and self-knowledge.
• Early assessment of professional interests (before age 13) is uncommon.
• The Iconographic Professional Interests Inventory (3IP) uses 65 images to represent job activities.

Purpose of the Study:

• To conduct an in-depth examination of the 3IP construct.
• To test additional models beyond the 19 vocational areas in the 3IP manual.
• To evaluate the psychometric properties of the 3IP inventory.

Main Methods:

• Utilized the 3IP inventory, comprising 65 stylized job-related pictures.
• Tested multiple models, including grouping vocational areas and Holland's RIASEC model.
• Analyzed item selection for 24 specific jobs.

Main Results:

• Most 3IP vocational areas were successfully grouped into four second-level areas: 'things,' 'people,' 'leisure,' and 'culture.'
• Holland's RIASEC model demonstrated effectiveness when applied to a specific selection of 24 jobs within the 3IP framework.
• The 3IP inventory exhibits good psychometric qualities.

Conclusions:

• The 3IP inventory is a valuable tool for assessing vocational interests.
• The inventory's structure supports broader categorization and alignment with established models like RIASEC.
• Enhancing the inventory with more targeted job representations could further improve its psychometric properties.
