PROBLEMThe adjective check list method of measuring the presence of affective states is an attractive alternative or supplement to the more widely used questionnaire and projective methods of assessment. However, substantial individual differences in the tendency to check few or many adjectives has posed a problem. Jackson and Minton(2) have attempted to control this response tendency by using a forced choice format, where S must endorse one or the other of two bipolar adjectives. Zuckerman(6) has offered a different solution which consists of scoring certain adjectives if left unchecked. Following this suggested solution, Zuckerman, Lubin, Vogel and Valerius (a) constructed the Multiple Affect Adjective Check ListToday (MAACL-Today). The MAACL-Today is designed to assess daily changes in levels of anxiety, hostility and depression.In a previous study by Herron, Bernstein and Rosen"), the MAACL-Today was administered to two groups of Veterans Administration patients scheduled for an elective surgical procedure: One group was tested 12-16 hours prior to surgery; the other was tested 12-30 hours prior to discharge, after recovery from surgery. No significant differences in MAACLToday scores were found. Subsequent correlational analysis led to the conclusion that affect scores were predominantly a function of the number of adjectives checked, and not of affect level. This study is designed to modify the previous methodology and to use another subject population in a continuing effort to delve deeper into the role of response set in the MAACLToday measure.
METHODThe MAACGTodayl was administered at the beginning of the period on Thursday of the 4th, 5th and 7th weeks of classes to an upper division course in psychological tests and measurements. The Ss were told that the instructor had used this particular adjective check list in a study of patients undergoing elective surgery in a V. A. Hospital, and that he was interested in comparing the responses of college students with those of the patients. The Ss, at the time of the first administration, were told that the check list would be passed out every Thursday for the next several weeks. To protect anonymity, 5 ' s were told to use some easily remembered code, number or symbol, in the space provided for a name. Their code, dong with the designation of their sex, would permit the instructor to identify each student's check list over the several weeks of repeated administration.The first two administrations of the check list were to serve as a control or low anxious condition; the third administration was to be a high anxious condition, since the midterm exam (and only examination, other than the final) had been scheduled (during the first week of classes) for Thursday of the 7th week. The check list was not administered during the 6th week because of the uncertainty as to whether anxiety would or wodd not be aroused by the prospect of an exam the following week.Of 47 students enrolled in the course, there were complete data on thirty-three.The check lists of these 33 Ss...
