The measurement of assertiveness and aggressiveness.

Area of Science:

• Psychology
• Social Psychology
• Behavioral Science

Background:

• Assertiveness is often broadly defined, encompassing distinct behavioral patterns.
• Previous measures may not differentiate between protective and acquisitive social behaviors.

Purpose of the Study:

• To introduce and validate the Bakker Assertiveness-Aggressiveness Inventory (BAAI).
• To differentiate between defensive (territory protection) and initiating (status augmentation) behaviors.
• To examine the relationship of these behaviors with demographic variables.

Main Methods:

• Development of a 36-item self-report inventory (BAAI).
• Administration of the inventory to a specific population.
• Correlational analysis with occupation level and educational attainment.

Main Results:

• Assertiveness scores significantly exceeded aggressiveness scores in a class focused on defensive behaviors.
• Aggressiveness scores showed a positive correlation with occupation level and years of schooling.
• Assertiveness scores did not correlate with occupation level or schooling.

Conclusions:

• The BAAI effectively distinguishes between defensive assertiveness and aggressiveness.
• Aggressiveness appears linked to socioeconomic and educational factors, unlike defensive assertiveness.
• The inventory provides a nuanced measure of social behavior, aiding further research.
