Aggressive Attitudes in Middle Schools: A Factor Structure and Criterion-Related Validity Study.

Area of Science:

• Educational Psychology
• Developmental Psychology
• School Psychology

Background:

• Student attitudes toward aggression are linked to individual aggressive behavior.
• Measuring school-wide normative beliefs about aggression presents significant challenges.
• Previous research has not adequately examined these measurement challenges.

Purpose of the Study:

• To investigate the factor structure, measurement invariance, and criterion-related validity of the six-item Aggressive Attitudes scale.
• To address measurement challenges in assessing school-wide normative beliefs about aggression.
• To provide a reliable tool for understanding aggression in school settings.

Main Methods:

• Utilized a large sample of 7th and 8th-grade students (n = 39,364) from 423 schools.
• Employed advanced statistical procedures accounting for clustered and ordinal data.
• Examined the factor structure, measurement invariance, and criterion-related validity of the Aggressive Attitudes scale.

Main Results:

• The Aggressive Attitudes scale demonstrated a robust second-order factor structure.
• Measurement invariance was confirmed across gender, grade, and race/ethnicity.
• Criterion-related validity was supported by correlations with eight student- and school-level aggression indices.

Conclusions:

• The Aggressive Attitudes scale is a psychometrically sound measure for assessing adolescent normative beliefs about aggression.
• The scale's invariance across demographic groups supports its use in diverse school populations.
• Findings support the scale's utility in predicting aggressive behaviors at individual and school levels.
