This study does not seek to generalize with respect to the possible differences between delinquent and nondelinquent girls, or even between a particular group of delinquent and nondelinquent girls. Its primary purpose is the analysis of the results of a series of tests of emotionality, or personality, when they are applied to two groups of girls who are manifestly different, on the average, in their personality adjustments. One of these groups was composed of 47 girls, aged 16 and 17, who were in the Tennessee Vocational School for Girls, ordinarily called the State Reform School, to which girls are committed by court as a result of one or more delinquencies of some type. This was the entire population with the designated ages. The other group was composed of 50 girls in West End High School, in Nashville, a public high school which is located in a somewhat favored portion of the city, both from an economic and social point of view. These girls were selected at random from the 16- and l7-year-old girls in the latter school. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
