Standaardisering van die Meyer-belangstellingsvraelys op volwassenes
The purpose of this investigation was to standardise the MB-10 on adults. As it has already been standardised for grade 7, grade 9 and grade 11 learners, as well as first year students, the next logical step would be to extend it to adults. This study is further motivated by a suggestion of the Psychometric Committee of the Vocational Council for Psychology that there is indeed a need to standardise the MB- 10 on adults. Altogether 233 adult volunteers between the ages of 22 and 55 years participated in this study. The average age of the male group (35 years) is more or less the same as that of the female group (34 years). The majority of the participants (184) are Afrikaans speaking. Regarding the level of education, marginally more men and women (51% and 52% respectively) have post-matric qualifications, whereas 49% of the men and 48% of the women only have a school qualification. From the investigation the following conclusions might be drawn: * The same form of the MB-10 which has already been standardised on other groups, can be used as a reliable and valid instrument of measurement for adult interest. * Item analysis has indicated that there are only a few items which did not make a positive contribution to the relevant field, but that the overwhelming majority of the item correlations are highly satisfactory. A possible reason for the low correlations may be that certain items that should have been simple enough for grade 7 learners, were too simplistic for adults. * No meaningful differences were found regarding interest between adults with different educational levels, except that persons with no post school qualifications tend to have a preference for business activities. Results of this investigation have resulted in the setting of separate norm tables for adult men and women.
