The purposes of the study were: (1) to determine whether the experience of attending a human relations workshop produces a change in anxiety levels as measured by two instruments, the Janet Taylor Manifest Anxiety Scale and the Anxiety Scale (Omnibus Personality Inventory); (2) to compare the mean anxiety scores of the experimental treatment group and the control group using the variables of sex, teaching level, and years of experience in public school teaching; and (3) to determine the retention effect on anxiety over an intervening time span of four months for the experimental treatment group. The following are conclusions derived from this study: 1. Whatever effect the experience of attending a human relations workshop had, it cannot be measured by the Anxiety Scale (OPI) or the TMAS. 2. No segment of a school population will experience increased anxiety as a result of attending a Thiokol human relations workshop (1). 3. No significant changes in levels of teacher anxiety can be expected from attending a one-week human relations workshop with the possible exception of individuals with six or more years’ experience who did report lowered anxiety. 4. There is no longitudinal effect on levels of anxiety for teachers as a result of a human relations workshop experience.
