Visual inspection is the primary method used to analyze graphed behavioral data produced by functional analyses of problem behavior. The purpose of this study was to examine rater reliability of functional analysis graphs using visual inspection. Forty-three participants responded to a one-time anonymous survey (N = 454) mailed to graduate…

The Preferred Items and Experiences Questionnaire (PIEQ) is a new instrument to assess reinforcer 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 consistency methods, and to test its validity.

The factor structure, psychometric properties, and relationship with personality variables of a Spanish version of the Savings Inventory-Revised (SI-R) are investigated in a sample of 381 undergraduate students. A maximum likelihood factor analysis suggests a three-factor structure, which is similar but not identical to that of the original…

This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from…
