Anonymous questionnaires are vital for sensitive research. A new subject-generated coding system accurately matched 75.2% of pretest-posttest pairs, proving effective for maintaining confidentiality in studies.

Area of Science:

  • Psychology
  • Research Methodology
  • Data Collection

Background:

  • Anonymous questionnaires are crucial for sensitive research topics.
  • Accurately matching pretests with posttests is challenging in anonymous studies.
  • The accuracy of existing subject-generated coding schemes is largely unknown.

Purpose of the Study:

  • To evaluate the accuracy of a subject-generated coding system for matching pretests and posttests in an anonymous study.
  • To determine the effectiveness of subject-generated codes in maintaining participant confidentiality.
  • To assess the feasibility of using such coding systems in research involving sensitive issues.

Main Methods:

  • Conducted an anonymous study with 745 students.
  • Implemented a subject-generated coding system for pretest-posttest matching.

  • Verified coding accuracy using an anonymous sticker identification system.

    • Main Results:

    • The subject-generated coding system achieved an accurate match rate of 75.2% for pretest-posttest pairs.
    • 22.1% of pairs remained unmatched.
    • Incorrect matches occurred in only 2.7% of cases.

    Conclusions:

    • Subject-generated coding systems are effective for matching pretests and posttests in anonymous research.
    • These systems significantly enhance confidentiality, which is critical for sensitive research.
    • The sticker identification system provides a reliable method for verifying coding accuracy.
