The People/Things and Data/Ideas scales are scored in such a manner that high scores are associated with the first pole listed (e.g., high scores on People/Things reflect greater interest in people than in things). In addition, weighted geometric composites of the 18 spherical scales are used to construct the RIASEC scales, Prediger’s 4 poles (People, Things, Data, and Ideas), and 3 summary dimensional scales (People vs Things, Data vs Ideas, and Prestige). ![]() To represent the combined scales across the three sets of 18 spherical scales, a set of 18 composite scores is calculated by taking the means of each scale across the three item types. So, 18 spherical scales are created separately for the occupational preference section, the activity preference section, and the activity competence belief section for a total of 54 spherical scales. The means of the six items are used to represent each of the 18 spherical scales of the PGI. Six items comprise each scale for each of the item types (activity preferences, activity competence beliefs, and occupational preferences). Because they provide very similar scales, it might be desirable to give only one for brevity. The other part of the PGI consists of 113 activities (108 tied to the spherical scales and 5 exploratory items) whereby the respondents respond twice, using a 7-point scale (1 = very strongly dislike, 7 = very strongly like) to rate the extent to which they like each occupation and then again using a 7-point scale (1 = unable to do, 7 = very competent) to rate their perceived competence. The two parts (occupational titles and activities) are generally administered together, but it is possible to administer either the occupational titles part or the activities part alone. ![]() One part consists of 108 occupational titles whereby the respondents are to rate the extent to which they like each occupation using a 7-point scale (1 = very strongly dislike, 7 = very strongly like). ![]() The PGI consists of two forms, based on item type, that can be used together or apart. The PGI can be accessed online or through a downloadable Windows file. There are two versions of the PGI: the PGI and the PGI-Short. It provides a wealth of information that can be used in career and educational planning. The Personal Globe Inventory (PGI) is an inventory that assesses interests and self-estimates of ability in a wide variety of areas. ![]()
