THE STUDY FOCUSED ON A COMPARATIVE ANALYSIS OF MALE AND FEMALE SELF-REPORTED DELINQUENCY INVOLVEMENT. THE GOALS OF THE ANALYSIS WERE (1) TO EXAMINE THE FREQUENCY OF ADOLESCENT SELF-REPORTED INVOLVEMENT IN A WIDE VARIETY OF OFFENSES, (2) TO DETERMINE THE DEGREE OF SPECIALIZATION OR VERSATILITY OF INVOLVEMENT IN THESE OFFENSES, AND (3) TO COMPARE MALES AND FEMALES, IN GENERAL AND BY RACE, ALONG THESE DIMENSIONS IN ORDER TO ISOLATE SIMILARITIES AND DIFFERENCES IN THEIR DELINQUENT INVOLVEMENT. DATA WERE OBTAINED FROM ANONYMOUS SELF-REPORT QUESTIONNAIRES WHICH WERE ADMINISTERED TO A 1977 SAMPLE OF 822 STUDENTS IN 2 MIDWESTERN URBAN HIGH SCHOOLS. ONE OF THE SCHOOLS WAS A LOWER-STATUS INNER-CITY SCHOOL AND THE OTHER WAS A HIGHER-STATUS SUBURBAN SCHOOL. THE MEAN AGE OF THE SUBJECTS WAS 16.68 YEARS. FEMALES CONSTITUTED 56.5 PERCENT OF THE SAMPLE, AND WHITES 48 PERCENT. A TOTAL OF 36 DELINQUENT ACTS WERE LISTED ON THE QUESTIONNAIRE. MAJOR FINDINGS ARE THAT (1) WITH THE EXCEPTION OF A FEW MINOR OFFENSES, MORE MALES THAN FEMALES REPORTED ENGAGING IN EACH OF THE 36 DELINQUENT ACTS; (2) THE OVERALL MALE-FEMALE RATIO FOR PERCENT REPORTING INVOLVEMENT IN EACH OF THE DELINQUENT OFFENSES IS 2.18, CONSIDERABLY SMALLER THAN THE OFFICIAL ARREST RATIO OF 3.72; (3) WHEN MEAN FREQUENCY OF INVOLVEMENT IN EACH OF THE DELINQUENT ACTS IS EXAMINED, ALMOST 28 PERCENT OF THE MALE-FEMALE DIFFERENCES ARE SHOWN TO BE INSIGNIFICANT, AND THERE IS CONSIDERABLE UNIFORMITY BETWEEN MALES AND FEMALES; (4) THERE ARE NO SIGNIFICANT DIFFERENCES BETWEEN NONWHITE AND WHITE MALES BUT THERE ARE DISTINCT DIFFERENCES IN TYPE OF INVOLVEMENT FOR NONWHITE AND WHITE FEMALES; AND (5) RANK ORDER CORRELATIONS INDICATE MORE UNIFORMITIES IN FREQUENCY AND TYPE OF DELINQUENCY INVOLVEMENT WITHIN RACIAL GROUPS THAN WITHIN SEX GROUPS. TABLES AND REFERENCES ARE PROVIDED. (PRG)
