Of the several techniques reported for the treatment of self-injurious behavior, response-contingent aversive stimu-lation and overcorrection seem to be the most successful. However, many procedures are precluded from use by legal or other restrictions. Thus, many procedures that are both ethnically and aesthetically tolerable to practitioners and the public must be developed. Facial screening (Lutkzer & Spencer, Note 1; Zegiob, Becker & Bristow, Note 2; Lutzker, Note 3), applying a terrycloth bib to cover the face contingent upon self-injurious behavior, has been shown to be effective. The purpose of this study was to investigate the parameters of facial screening with two subjects. Specifically investigated were: a) the role of non-contingent v~. contingent facial screening in therapy and extra-therapy setting; and b) the role of opaque vs. translucent bibs. In the first study, using a multiple baseline design, it was found that non-contingent facial screening was effective only after a history of pairing with contingent facial screening. While non-contingent facial screening reduced self-injurious behavior in two settings, it did not eliminate self-injurious behavior in all three settings in which it was observed. In the second study a reversal design-component analysis was used to compare a translucent to an opaque bib. The translucent bib was ineffective in reducing the self-injurious behavior while the opaque bib eliminated self-injurious behavior as long as facial screening was applied consistently.
