• Partly related to cultural differences
• Partly related to actual wording of sentences
• Partly related to direction on answering scale
  causing confusion
• Partly related to inaccuracy of translation

18
Recommendation

• Be very careful when instructing clients how to
  fill in the questionnaire

• Idea to homogenize the statements in order to
  make the answering scale point in the same
  direction to avoid confusion
