The first four items of the scale (see above) loaded high
([0.67) on a separate factor and are classified as ‘severe
delinquent behaviour’. Respondents with the minimum
score of 11 on the delinquency scale were classified as
reporting ‘no delinquency’. Those coded into the frequent
delinquency category scored more than 15 on the delinquency scale (which represents the upper quartile) or
reported at least one of the four severe delinquent behaviours. All others were coded in the category of sometimes
delinquency.
