ALL BEHAVIORAL DATA WERE GATHERED IN PERIODS WHEN THE SUBJECTS WERE NOT CONFINED IN PENITENTIARIES OR OTHER INSTITUTIONS. THE RESULTS SHOWED THAT DELINQUENTS AND NON-DELINQUENTS WERE NOT RELIABLY DIFFERENT ON A WIDE VARIETY OF LEGAL AND ILLEGAL BEHAVIORS. THE TWO GROUPS SHOWED SIMILAR PATTERNS IN SUCH LEGAL BEHAVIORS AS WELFARE, CHARITY, USE OF PRESCRIPTIONS, AND SOME SEXUAL BEHAVIORS. THE GROUPS ALSO DID NOT DIFFER RELIABLY ON NON-PRESCRIPTION USE OF DRUGS. HOWEVER, THE TWO GROUPS WERE DIFFERENT FOR SUCH BEHAVIORS AS LEGAL EARNINGS, HETEROSEXUAL INTERCOURSE, NON-DELINQUENT ASSOCIATIONS, DELINQUENT ASSOCIATIONS, CHURCH ATTENDANCE, ILLEGAL EARNINGS, AGGRESSION, AND NON-PRESCRIPTION OPIATE USE. NON-DELINQUENTS WERE FOUND TO ENGAGE IN SIGNIFICANT AMOUNTS OF CERTAIN KINDS OF ILLEGAL BEHAVIOR: ILLEGAL EARNINGS, PROPERTY DAMAGE, BARE-HANDS AGGRESSION, AND NON-PRESCRIPTION CANNABIS USE. IMPLICATIONS OF THIS NON-DELINQUENT ILLEGAL BEHAVIOR ARE BRIEFLY EXAMINED.
