Die gebruikswaarde van J.L. Holland se SDS–vraelys in beroepsvoorligting vir Swart leerlinge
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. CHAPTER 2: LITERATURE STUDY In this chapter it was necessary to look at the following aspects: • theories of vocational choice and • aptitude, attitude and interest. In the section on theories of vocational choice or career development, reference was made to the theories of Ginzberg and associates. Super, Roe, Hoppock, Holland, decision-making models as well as the behavioristic, sociological and psychoanalitical approaches. 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 used. A random sample was selected. pupils of Lebowa and Gazankulu. The sample consisted of standard 10 The psychometric tests included in the vocational guidance programme were: • an aptitude test battery (AAT); • an interest questionnaire (SDS) and • the Survey of Study Habits and Attitudes (SSHA). Finally the statistical methods were discussed, namely item analysis, means ana standard deviations, correlations, factor analysis, procedures to determine consistency and congruency, stepwise regression and distribution of SDS-codes. CHAPTER 4: DISCUSSION OF RESULTS In summary it is clear that the results in general give an indication that the SDS has utility with blacks. The item analysis of the 228 items indicated that only 15 items needed revision. The means indicated that there is no notable difference between this and other samples. The reliability coefficients are satisfactory and are good in comparison with the results obtained by Holland and others. The intercorrelations between the six personality types confirmed relationships as described by Holland. The factor analysis results indicated that the SDS has a definite structure. Procedures conducted to determine consistency and congruency as defined by Holland confirmed the use of the concepts. The Realistic, Enterprising and Investigative fields were identified as contributing to the prediction of academic achievement. It was also indicated that most of the pupils resemble the Social personality type as defined by Holland. CHAPTER 5: CONCLUSION In summary the conclusion can be made that the SDS has utility for use with black pupils in a vocational guidance situation.
