The dimensionality of career indecisiveness has continually eluded researchers for several years. These measures have been either purely theoretical or purely empirical, neglecting the other domain. A relatively new instrument, the Career Decision Difficulties Questionnaire (CDDQ), is based on a taxonomy of decision-making difficulties. This study assesses the reliability and construct validity of the CDDQ, along with differences between decided and undecided groups. The sample included 268 university students. Convergent validity was assessed using the Career Decision Scale (CDS). Discriminant validity was assessed using measures of anxiety and social desirability. The CDDQ showed convergence with the CDS, and discriminated against both anxiety and social desirability. Differences between groups were statistically significant on most decision making difficulty scales. The results provide support for the reliability and validity of the CDDQ, suggesting that this measure may be useful in attempting to understand the multidimensionality of career indecisiveness and further assist in the development of a more comprehensive and accurate theoretical perspective of the construct of career indecisiveness.

Since we believe that, other things being equal, root resorption will occur more frequently in patients treated orthodontically than in individuals who have not received orthodontic treatment, it has been our aim to discover if this belief is based upon fact and, if so, to what extent this premise can be applied for the purpose of prognosticating root resorption.Stimulus to this investigation was given by Ketcham who urged "all orthodontists to secure accurate radiographic surveys of allcases before treatment, and to recheck them often, compiling results so that many accurate data may be secured" (1).A preliminary report was made in 1936 of the incidence of root resorption developing in patients receiving orthodontic treatment in the undergraduate clinic in the School of Dentistry of the University of Minnesota (2). Serial roentgenograms of 439 orthodontic patients, whose ages ranged from 7 to 21 years, were studied. None of these patients showed any evidence of root resorption before orthodontic treatment was instituted. At the end of the first year of treatment, 49 per cent of the 439 patients showed root resorption; and at the end of two years of treatment, 75 per cent of the remaining 277 patients demonstrated root resorption.For purposes of comparison the roentgenograms of 4,560 patients with no history of orthodontic treatment were studied. The individuals in this group ranged in age from 7 to 79 years, and the incidence of root resorption in this group was 13 per cent. However, when the 739 patients ranging from 7 to 21 years of age, the age group compa-1
