University Counseling Center clientele in 49 universities were surveyed by the use of the Counseling Services Assessment Blank. Respondents provided demographic and diagnostic self descriptions, self report assessments of specific theraeutic gains, and evaluations of agency services. The diagnostic self descriptions were based on a two-dimensional system. The first dimension involved the client's ranking of his or her problem-goals in counseling as either vocational, personal, or educational. The second dimension involved a ranking of the possible causes of the problems as either lack of information about self, lack of information about the environment, self conflict, conflict with others, or lack of skill. The five gain items corresponded directly to the five cause items so that, for example, the first gain item asked for the client's evaluation of gain in information about self. There were also 11 service evaluation items concerning helpfulness of tests, confidentiality of counselors and groups, ratings of individual, group, and overall counseling experiences along with helpfulness ratings of individual and group counselors and other group members. Other items assessed were physical facilities and the client's perception of adequacy of self for seeking counseling. In the analysis of sex differences, it was found that: (1) females sought more counseling than males; (2) females saw themselves with more problems and engaged in longer therapy periods; and (3) both sexes increased focus equally on themselves each successive academic year, with females beginning with a higher focus in the freshman year.
