Vocational Diagnostic Signs for Decision-Making Ability Across Three Populations

A sample of 1,005 high school juniors, 692 college juniors, and at least 140 employed adults was administered the Self-Directed Search and validation criteria. The data was used by John L. Holland to examine the validity of theoretically-derived vocational diagnostic signs for predicting self-knowledge, occupational knowledge, and decision-making ability. The study found that signs for good decision-making ability predicted scores on a decision-making task more efficiently than non-SDS variables.

Use Cases

• Validate psychometric instruments for career maturity based on the Career Maturity Inventory scores.
• Predict decision-making ability in vocational contexts based on Self-Directed Search profile consistency and differentiation.
• Analyze the relationship between vocational diagnostic signs and personality constructs like identity and anomy.
• Compare vocational assessment outcomes across distinct populations like high school students, college students, and employed adults.

Strengths

• Data was collected from three distinct and sizable samples, including over 1,000 high school juniors.
• Validation used multiple established criteria, including the Career Maturity Inventory and specific decision-making tasks.
• The study provides clear, testable results on the predictive validity of specific diagnostic signs.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The description states that signs for self and occupational knowledge had no convergent or discriminant validity.
