Development and Psychometric Evaluation of an Instrument to Assess Reinforcer Preferences The Preferred Items and Experiences Questionnaire EDWARD P. SARAFINO JAMES A. GRAHAM The College of New Jersey The Preferred Items and Experiences Questionnaire (PIEQ) is a new instrument to assess rein- forcer preferences in adolescents and adults. Research was conducted with college and high school students to develop the PIEQ, to examine its reliability with test-retest and internal con- sistency methods, and to test its validity. This research provides support for the PIEQ’s relia- bility and validity. Keywords: assessment; reinforcer; preferences The application of effective reinforcers is a cornerstone of behav- ior modification program design and implementation. Determining which consequences will reinforce a person’s behavior can be accomplished in several ways (Sarafino, 2001). For example, one way uses structured tests, presenting an array of stimuli and observ- ing which ones the person chooses. Research has shown that rein- forcers identified with structured tests of individuals’preferences are AUTHORS’NOTE:We are indebted to Edward Barry, principal of Ewing High School, and the school’s teachers for designating and preparing the classes for recruitment and for encour- aging students to participate.

Another method for assess- ing reinforcer preferences has the individual rate his or her liking of potential reinforcers in a questionnaire. The Reinforcement Survey Schedule (RSS) is a very detailed and extensive questionnaire for assessing possible reinforcers for adults (Cautela & Kastenbaum, 1967). It lists 148 potential reinforcers and has respondents rate each for the “pleasure it gives,” using a 5-point scale from not at all to very much, and it takes 20 to 30 minutes to complete. Research has found evidence of the instrument’s validity (Cautela & Lynch, 1983) and has shown that it has good reliability, with median test-retest correlations ranging from .67 to .73 for the full scale (Kleinknecht, McCormick, & Thorndike, 1973). Different ver- sions of the RSS have been developed for specific populations, such as adolescents and individuals with certain psychiatric disorders, and the scale has been useful in research and in treating clients in private practice and institutions (Cautela & Lynch, 1983). But the various ver- sions of the RSS have limitations. For example, many of the rein- forcers they list could be difficult or unethical to control and administer, such as “nude men” and “being right in an argument.” Other reinforcers are specified in extreme detail, as in the 17 listed types of reading material (e.g., “mystery,” “travel,” and “science”), making the survey long to fill out. Because of these limitations, we have developed a new survey to assess reinforcer preferences—a 59-item instrument, called the Preferred Items and Experiences Questionnaire (PIEQ), that is intended for use with adolescents and adults. An important advantage of the PIEQ is that almost all of the reinforcers it lists can be controlled and administered by professionals, such as therapists and teachers, and by family members and clients (in self-management). Two studies were conducted to develop the PIEQ and assess its psychometric properties. STUDY 1—METHOD AND RESULTS An initial version of the PIEQ was developed by perusing the rel- evant literature and by interviewing college students to identify Downloaded from http://bmo.sagepub.com by on November 8, 2007 © 2006 SAGE Publications.

Sarafino, Graham / ASSESSING REINFORCER PREFERENCES 837 items or experiences they think teenagers and adults like or find pleasurable. These procedures identified 49 potential reinforcers that were separated for the questionnaire into seven thematic categories (see Sarafino, 2001, Figure 4.2, for the complete scale). Study 1 was carried out to examine the items in the initial version of the PIEQ, make changes to them, and assess the scale’s reliability and validity. PARTICIPANTS The participants in Study 1 were 52 undergraduates enrolled in an upper-division psychology course; approximately 86% were females. MATERIALS AND PROCEDURE The thematic categories of the initial PIEQ version and examples of the reinforcers included are: tangible items (e.g., new clothes, music recordings); foods (candy, popcorn); beverages (soft drinks, juices); outcomes for work, chores, or skills (money, praise or feed- back); friends’ or relatives’ actions (giving affection, invitation for a party); passive leisure activities (watching TV, listening to music); and active leisure activities (playing athletics, reading). No category had fewer than five reinforcers in it. The instructions asked the par- ticipants to use a 5-point scale (0 = not at all,4 = very much) to “rate how much you like to receive, have, or do” each item or experience. The participants were also told to assume that the items or experi- ences available for each listed reinforcer were “about as good as they could get” for that type of reinforcer (i.e., ones “you would choose from an array” of similar options). Each category had spaces in which participants could add items or experiences that were not included in the list. Testing was conducted in three 10- to 15-minute sessions during class periods, 1 week apart, beginning with the first meeting of the semester. The students were not told in advance that testing would occur. To coordinate surveys across sessions and maintain anonymity, each participant composed and wrote on the materials a code based on his or her birth month and home zip code. For the first and third sessions, the procedure was exactly as described above; the Downloaded from http://bmo.sagepub.com by on November 8, 2007 © 2006 SAGE Publications. All rights reserved.
