5. Limitations and recommendations

The following recommendations have been identified which could open avenues for further research:

• The Zulu questionnaire of the Discus instrument was withdrawn from the study because respondents indicated difficulty in understanding the standard of language used in the questionnaire. It is therefore recommended that the Zulu questionnaire be drafted on the basis of day-to-day language use.
• For future research it would be interesting to include other instruments to determine whether Discus also correlates with other instruments. It needs to be pointed out that the study of criterion-related validity is based on the measuring of criteria against each other. If any two criteria are not perfectly matched, the validity analysis may be affected. For this reason, this type of study has always proved difficult.
• A factor analysis on the Discus could be undertaken for further research.
• It is recommended that the instructions to the questionnaire be amended, so as to reflect a specific role in terms of which the individual must complete the questionnaire. It was found that the general manner in which the instructions are presently set out caused individuals to be uncertain as to the role that was being measured, especially those who had more than one role to fulfil in the work situation.
