Thesis (MA)--PU vir CHO, 1988 ; CHAPTER 1: INTRODUCTION AND OBJECTIVES 1. INTRODUCTION: In view of the great demand for career guidance, it was necessary to give attention to the development and adaptation of psychometric instruments. This led to important development in this area. The Self-Directed Search (SDS) interest questionnaire of J.L. Holland was included in a career guidance programme for black matriculation pupils resulting in the need to investigate the utility of the SDS for black pupils. The study was conducted with this objective in mind. 2. OBJECTIVES: The objectives of this study were as follows: 2.1 PRIMARY OBJECTIVE: 2.1.1 Determining the psychometric suitability of the SDS for blacks with respect to some psychometric and statistical qualities, namely item analysis, means, reliability, intercorrelations of the fields and the factorial structure of the construct. 2.2 SECONDARY OBJECTIVE: 2.2.1 Determining the utility of the SDS in a career guidance set-up for this group, by giving attention to the principles of consistency and congruency; 2.2.2 determining the utility of the SDS as part of a career guidance programme for blacks by using stepwise regression and 2.2.3 determining the distribution of the interests for this group as indicated by the SDS.

Then aptituae, attitude and interest were discussed with special emphasis on the conceptual description, structure and measurement of the concepts. CHAPTER 3: METHOD OF INVESTIGATION In this chapter the following aspects were discussed: • the sample; • the psychometric tests used in the research and • the statistical methods ...
