A study was conducted to develop and validate a procedure for efficiently identifying critical affective behaviors necessary for success in a given role or job. Subjects were 2 groups of 10 cosmetology instructors each and 1 group of 10 employers of cosmetologists. Three instrument packages were used: the first was used by all members of the three groups to generate individual lists of affective behaviors necessary to perform the functions of a cosmetologist; the second was used by one coordinator from each group to develop a combined list that included all contributions of each member of the group and eliminated repetitions; the third used the combined list to generate ratings of each behavior from each of the subjects in terms of importance to success on the job. A 6-point Likert scale was used to generate the ratings. Analyses indicated that the extent of disagreement on the exact job-related affective behaviors important to success as a cosmetologist between groups was large. The overall conclusion was that the Performance-Based Affective Behavior Identification (PBABI) process is an effective one for identifying role-related affective behaviors. The procedure can be implemented through the mail and produces lists of affective behaviors stated in a behavioral format that represents group consensus. (Includes 32 references and 8 appendices containing project letters, the PBABI module, and mean ratings and frequencies of behaviors.) (CML)
