The study examined the Personal Orientation Inventory (POI) scale factor structure using as a population 397 young adults (average age 26) members of rural disadvantaged families of average intelligence attending the Mountain-Plains program. The factor structure was compared with that of a similar study of college students. Tables show factor loadings for 12 POI scales for both studies and partial correlation matrixes for the POI scales characterizing the three factors. Findings indicate that dimensions of positive mental health do not seem to differ markedly between college students (a young population heavily weighed with advantaged persons) and Mountain-Plains students (an older population that is 100 percent disadvantaged). The findings of highly similar factors in the two studies is of particular importance to persons working with populations dissimilar to the largely collegiate group which has been the predominant focus of POI research. Persons dealing with other ages and social classes can now more confidently use the POI. A POI scale intercorrelation matrix for the 397 students and POI scale description are appended. (Author/NH)
