THE NATIONAL EVALUATION OF THE DSO PROGRAM IS MASSIVE IN SCOPE AS IT WILL ENTAIL THE PROCESSING OF OVER 6,000 CLIENT-CENTERED DATA FORMS EACH MONTH FOR EIGHTEEN MONTHS. SEVEN DIFFERENT TYPES OF STATUS OFFENDER PROGRAMS LOCATED IN VARIOUS AREAS OF THE COUNTRY WILL BE REPORTING TO THE SOCIAL SCIENCE RESEARCH INSTITUTE OF THE UNIVERSITY OF SOUTHERN CALIFORNIA. DATA ANALYSES TO BE PERFORMED INCLUDE THE COMPARATIVE ANALYSIS OF CONTROL VARIABLES (DEMOGRAPHIC CHARACTERISTICS OF JUVENILE CLIENTS IN DSO PROGRAMS, INDIVIDUAL PROGRAM CLIENT POPULATION STATISTICS, AND COMMUNITY TOLERANCE MEASUREMENTS) WITH THE DEPENDENT VARIABLES OF OFFICIAL DELINQUENCY RECORDS, SELF-REPORTED DELINQUENCY, AND CLIENT SOCIAL ADJUSTMENT DATA. DATA WILL BE CROSS- CLASSIFIED TO DETERMINE THE EFFECTS OF THE VARIOUS TYPES OF DSO PROGRAMS (THE INDEPENDENT VARIABLES OF THE STUDY). THESE PROGRAMS HAVE BEEN PLACED IN THE FOLLOWING GROUPINGS: DIVERSION, DIAGNOSTIC, AND EVALUATION SCREENING UNITS; SHELTER CARE HOMES (RESIDENCY OF 30 DAYS OR LESS); GROUP HOMES (OVER 30 DAYS); FOSTER HOMES; MULTIPLE SERVICE CENTERS (SUCH AS YOUTH SERVICES BUREAUS); OUTREACH INTERVENTION (ACTIVE EFFORTS TO INTERVENE IN AND ATTEMPT TO MODIFY VARIOUS PHYSICAL, SOCIAL, AND EMOTIONAL CIRCUMSTANCES OF THE CLIENT); AND SERVICES WHICH OFFER COUNSELING ONLY. INSTRUCTIONS FOR CODING AND BLANK COPIES OF ALL THE DATA COLLECTION INSTRUMENTS ARE PROVIDED. THESE FORMS ARE DESIGNED TO BE PROCESSED BY OPTICAL SCANNING EQUIPMENT. PROCEDURES FOR TRACKING LOST OR INCOMPLETE DATA COLLECTION FORMS ARE DESCRIBED.
