This study examined the reliability and validity of a new measure, an inventory designed for the assessment of Dependent Personality traits. The new scale, the Dependent Personality Inventory, uses a dichotomous (True/ False) answer format and produces 8 subscales which correspond with the individual criterion of the disorder as defined by the current Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV-TR). The scale was administered to a sample of 82 students attending a large mid-western university in the United States. Factor analysis of the DPI using a Principle Components Analysis produced two main factors. Additional analysis showed a differential correlation between these two factors and the Dependent Personality Questionnaire (DPQ Hyler, 1994) and the Minnesota Multiphasic Personality Inventory-2 Social Introversion Subscales 1-3 (MMPI-2 Si1-3 Ben-Porath, Hostetler, Butcher & Graham, 1989). The DPQ correlated highly with the DPI factor 1(r=-.65, p<.00) and to a lesser degree with factor 2 (r=-.29, p<.02). All three Si subscales of the MMPI-2 correlated highly with factor 1 (r=-.43, p<.00 r=-.32, p<.00 r=-.50, p< .00) respectively while only subscales 1 and 3 correlate with factor 2 (r=-.24, p<.05 r=-.39, p<.00) respectively. The results support both the reliability and validity of the DPI as a screening measure in a college student sample. Recommendations for additional studies using the DPI are discussed
