THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE DIFFERENCES BETWEEN 22 CONFERENCES PLANNED WITHOUT PARTICIPATION REPRESENTATION AND 25 PLANNED WITH PARTICIPATION REPRESENTATION ON THREE MEASURES OF PROGRAM EFFECTIVENESS--(1) PARTICIPANTS' PERCEPTION OF PROGRAM RELEVANCE TO PERSONAL MOTIVES, (2) THEIR EXPRESSED SATISFACTION WITH THE PROGRAM, AND (3) THEIR EXPRESSED INTEREST IN CONTINUING EDUCATIVE ACTIVITY. A CONFERENCE EVALUATION FORM WAS CONSTRUCTED, PRETESTED, AND ADMINISTERED TO 1,026 MEN AND WOMEN ATTENDING CONFERENCES IN 1965 AT FIVE UNIVERSITY RESIDENTIAL CENTERS. THESE CONFERENCES WERE RANDOMLY DRAWN WITHIN THE TWO TYPES OF PLANNING. THE MAJORITY WERE DIRECTED TO INCREASING VOCATIONAL OR OCCUPATIONAL COMPETENCY. DEMOGRAPHIC FACTORS OF AGE (36-55), SEX (MOSTLY MEN), EDUCATIONAL LEVEL (MOSTLY COLLEGE GRADUATES), AND PREVIOUS ATTENDANCE AT CONFERENCES (59 PERCENT) SHOWED NO DIFFERENCES BETWEEN THE GROUPS OF PARTICIPANTS. FINDINGS SHOWED THAT PARTICIPANT PERCEPTION OF CONFERENCE RELEVANCE TO HIS PERSONAL MOTIVES AND HIS SATISFACTION WITH IT WERE GREATER IN CONFERENCES PLANNED WITH PARTICIPATION REPRESENTATION. AN INTEREST INVENTORY DID NOT SHOW SIGNIFICANT DIFFERENCES BETWEEN THE TWO GROUPS. IT DID APPEAR, HOWEVER, THAT PROGRAMS PLANNED WITHOUT PARTICIPANT REPRESENTATION RANKED HIGHER ON ACQUISITION OF KNOWLEDGE, AND PROGRAMS PLANNED WITH REPRESENTATION RANKED HIGHER IN AN ASSOCIATIONAL-PARTICIPATION DIMENSION. THIS MATERIAL WAS SUBMITTED AS A DISSERTATION TO THE UNIVERSITY OF CHICAGO, 1966, 160 PAGES. (EB)
