Summary
This study validates the 14-item Changes in Sexual Functioning Questionnaire (CSFQ-14) for assessing sexual dysfunction. The CSFQ-14 demonstrates strong reliability and validity for measuring desire, arousal, and orgasm.
Area of Science:
- Psychometrics
- Sexual Health
- Clinical Psychology
Background:
- The Changes in Sexual Functioning Questionnaire (CSFQ) is a 36-item tool for assessing sexual functioning across five scales.
- Existing instruments may require adaptation for specific research or clinical needs.
Purpose of the Study:
- To document the internal consistency and factor structure of a shortened, 14-item version of the CSFQ (CSFQ-14).
- To confirm the construct validity of the CSFQ-14 as a measure of sexual dysfunction.
- To evaluate the reliability of the CSFQ-14 and its scales.
Main Methods:
- Factor analysis was employed to assess the construct validity of the CSFQ-14.
- Internal consistency was evaluated for the CSFQ-14 and its derived scales.
Main Results:
- The 14-item CSFQ-14 yields scores for three scales: desire, arousal, and orgasm, aligning with the sexual response cycle.
- Factor analysis confirmed the construct validity of the CSFQ-14 as a global measure of sexual dysfunction.
- The CSFQ-14 and its individual scales demonstrated strong internal reliability.
Conclusions:
- The CSFQ-14 is a reliable and valid instrument for assessing sexual functioning.
- The shortened version effectively measures key aspects of sexual response, including desire, arousal, and orgasm.
- The CSFQ-14 provides a robust tool for both clinical and research applications in sexual health.
