A new measure is created to assess how delinquent an adolescent is. It asks respondents to rate how often they engage in delinquent acts such as using drugs, getting into fights, engage in theft etc.The authors report that the scale has a test-retest reliability over a 2 week period of .81. The authors also reported that they looked at how well the new measure correlated with a well-validated measure of juvenile delinquency.The correlation they found between scores on the two measures was .56.Do you think this is a good measure? why or why not?
