Item Constructing the Puerto Rico Self-Concept Scale: Problems and procedures(1981) Abadzi, Helen; Florez, SoniaThe Puerto Rico self-concept scale was developed for the purpose of assessing the relationship of self-concept with academic achievement and other school-related variables in Puerto Rico. An 88-item scale that can measure self-concept in the 4th, 7th, and 10th grades was constructed. Empirical criterion keying was used for the development of items that were also adapted to the phraseology used by local students. After small-group testing, the 264- item bank was administered to 2,445 students. Item analyses focused on item discrimination. Scores showed a low but significant correlation with previous’ year’s grade point average. Overall scale reliability was .93. A 34-item short form had overall reliability of .84. Preliminary norms were prepared from existing data.
