ROTTER INCOMPELETE SENTENCEBLANK (RISB)
INTRODUCTION
PURPOSE OF RISB
The Rotters incomplete sentence blank is an attempt to standardize the sentence completion method for the use at college level. Forty stems are completed by the subject. These completions are then scored by comparing them against typical items in empirically derived scoring manuals for men and women and byassigning to each response a scale value from 0to6. The total score is an index of maladjustment
THE SENTENCE COMPLETION METHOD
The sentence completion method of studying personality is a semi structured projective technique in which the subject is asked to finish a sentence for which the first word or words are supplied. As in other projective devices, it is assumed that the subject reflects his ownwishes, desires, fears and attitudes in the sentences he makes. Historically, the incomplete sentence method is related most closely to the word association test. In some test incomplete sentences tests only a single word or brief response is called for; the major differences appears to be in the length of the stimulus. In the sentence completion tests, tendencies to block and to twist the meaningof the stimulus words appear and the responses may be categorized in a somewhat similar fashion to the word association method.
DEVELOPMENT OF ISB
The Incomplete Sentence Blank consists of forty items revised from a form used by Rotter and Willermann (11) in the army. This form was, in turn, a revision of blanks used by Shor (15), Hutt(5), and Holzberg (4) at the Mason General Hospital. In thedevelopment of the ISB, two objectives were kept in mind. One aim was to provide a technique which could be used objectively for screening and experimental purposes. It was felt that this technique should have at least some of the advantages of projective methods, and also be economical from the point of view of administration and scoring. A second goal was to obtain information of ratherspecific diagnostic value for treatment purposes.
The Incomplete Sentence Blank can be used, of course, for general interpretation with a variety of subjects in much the same manner that a clinician trained in dynamic psychology uses any projective material. However, a feature of ISB is that one can derive a single over-all adjustment score. This over-all adjustment score is of particular value forscreening purposes with college students and in experimental studies. The ISB has also been used in a vocational guidance center to select students requiring broader counseling than was usually given, in experimental studies of the effect of psychotherapy and in investigations of the relationship of adjustment to a variety of variables.
PSYCHOMETRIC PROPERTIES 1.RELIABILITY
Since the items on anincomplete sentence blank are not equivalent, the odd even technique for determining reliability is not applicable and would tend to give minimum estimate of internal consistency. Therefore items on the ISB were divided into two halves deemed as nearly equivalent as possible. This yielded a corrected split-half reliability of .84 when based on the records of 124 male college students, and .83 whenbased on 71 female students. Inter-scorer reliability for two scorer trained by the authors was .91 when based on male records and .96 for female records.
2. VALIDITY
The Incomplete Sentence Blank was validated on groups of subjects which did not include any of cases used in developing the scoring principles and the scoring manuals. Scoring of the blanks was done “blindly” the scorer neverknew whether the test blank was supposed to be that of a maladjusted or an adjusted subject. Validity data were obtained for the two sexes separately since the scoring manuals differ. The subjects include 82 females and 124 males who were classified as either adjusted or maladjusted i.e., as needing personal counseling or as not needing such counseling. A cutting score of 135 provided a very...
