The Gynaecologic Leiden Questionnaire: psychometric properties of a self-report questionnaire of sexual function and vaginal changes for gynaecological cancer patients.
BACKGROUND
The aim of this study was to investigate the psychometric properties of the items concerning sexual functioning of the Gynaecologic Leiden Questionnaire (LQ), which consists of items for post operative morbidity for women with cancer.


METHODS
The total study sample consisted of 198 subjects: 66 patients treated for cervical cancer, 66 patients with sexual complaints and 66 subjects from the general population.


RESULTS
By means of factor analysis three subscales were derived: Female Sexual Complaints, Female Sexual Function and Female Orgasm. The reliability of the subscales appeared to be satisfactory. The scores on the three subscales differentiated well between the patients treated for cervical cancer, patients with sexual complaints and the subjects from the general population. Furthermore, the subscales were sensitive to changes within the patients treated for cervical cancer. The convergent and divergent construct validities of the LQ were investigated using other instruments measuring sexual functioning, sexual dissatisfaction, marital distress, general life distress and psychological distress. The LQ subscales were found to represent relatively independent constructs.


CONCLUSIONS
The results support the reliability and psychometric validity of the LQ in the assessment of sexual functioning and vaginal changes in gynaecological cancer patients.
