Die betroubaarheid en geldigheid van 'n assertiwiteitsvraelys vir toesighouers in die goudmynbedryf
Abstract
Assertiveness training forms an important component of training in the gold mining industry,
because it affects productivity as well as the nature of interpersonal relationships. Assertion
involves standing up for personal rights and expressing thoughts, feelings and beliefs in direct,
honest, and appropriate ways which do not violate another person's rights. Surveys have
indicated that supervisors at the Vaal River Gold Mine have limited skills of assertiveness. This
deficiency raises problems in interpersonal relationships in the work situation and has a negative
effect on productivity. A reliable and valid questionnaire to determine the assertiveness of the
Vaal River Gold Mine Supervisors is therefore a necessity. The general aim of this research was
to investigate the reliability and validity of an assertiveness questionnaire at the Vaal River Gold
Mine. The research hypotheses were tested by using a survey design as well as an experimental
design. Two research groups were used for the research. The research groups were comprised of
supervisors of the Vaal River Gold Mine. The first group was exposed to the survey design with
the following Paterson job gradings: 201 supervisors of the B5; B6/7 grading; 69 supervisors
of the C1, C2 and C3 grading; 129 supervisors of the C4/5 grading; and finally 23 supervisors
of the D1/2 grading. The second group consisted of 62 supervisors selected at random from a
group of 126 supervisors that were targeted for assertiveness training.
The measurmg instruments applicable to this research were the Vaal River Gold Mine
assertiveness questionnaire, the Rathus Assertiveness Schedule (RAS) and the Sixteen
Personality Factor Questionnaire (16 PF).
The results of the empirical survey indicated that the questionnaire currently being used were not
reliable and valid and did not satisfy the requirements of the evaluation of supervisors at the Vaal
River Gold Mine. The questionnaire was statistically analysed, and an improved questionnaire
was statistically processed.
