Abstract:
This study presents both the construction procedures and the results obtained with a 16-
items Disruptive Behavior Scale Professed by Students (DBS-PS) for Portuguese students.
The sample was made of 915 subjects from the 7th, the 8th, and the 9th grades. Results
obtained with that self-report instrument were analyzed, and measures of reliability and
of construct and concurrent discrimination were estimated. Three specific factors were
identified for the school disruption through varimax-rotation factor analysis. These factors
accounted for 51 per cent of the total variance. Reliability coefficients ranged between
.67 and .88 for different factors and groups (socio-economic status, residential zone, sex,
age and grade). Concurrent validity coefficients were satisfactory. Results were in accordance
with the psychometric theory of psychological evaluation.
Key words:
disruptive behaviour, violence in the school, assessment.
