The NEW CLASSIFICATION TECHNIQUES Task seeks through psychological techniques to keep up to date and effective the aptitude area measures used by the Army in classification of its enlisted personnel. A major effort is devoted to research on attitudes, interests, and other motivational factors with the objective of developing measures which will expand the scope of the Army Classification Battery ACB and add to its differential prediction. The present study concerns validation of the Army Job Activities Questionnaire-Mechanical AJAQ-M, a new interest questionnaire, constructed to measure aspects of enduring motivation of the new recruit predictive of MOS training and performance in different types of jobs in the mechanical domain. The AJAQ-M contains four major types of items organized into four sections Section I, expressions of positive or negative valence of particular job activities Section II, forced-choice preferences for job conditions Section III, expressions of valence for specifically-named jobs and Section IV, a checklist of mechanical job activities actually performed. Statistical analyses are described from which were derived eight job-motivation scales and three empirical scales valid for performance in five construction and mechanical MOS. As a whole, results indicated some possibility that the motivational scales of the AJAQ-M could add to the differential validity of ACB cognitive measures.
