If the inventory of a questionnaire is relatively homogeneous and unambiguous, then the inter-item correlation will be high.
All participants in the clinical trials underwent a baseline visit including physical measurements (height, weight, blood pressure, heart rate, waist and hip circumferences), blood specimen collection, a medication/supplement inventory, and completion of questionnaires on medical and family/reproductive history, lifestyle/behavioural factors, and quality of life.
Wording changes were based on the Family Inventory of Life Events questionnaire [ 117, 118].
All participants were evaluated by using a semi-structured questionnaire, the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire and the Sexual Quality of Life questionnaire (SQoL).
However, the responsiveness of the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire, a highly recommended questionnaire by the International Consultation of Incontinence to assess sexual function in patients with incontinence, has not been established.
The Brief Form of the World Health Organization's Quality of Life Questionnaire (WHOQOL-BREF, Taiwanese version); Short-Form 36; Inventory of Socially Supportive Behavior questionnaire; Geriatric Depression Scale-short form; Barthel Index; and instrumental activities of daily living were used.
On the first and last days of class, the students completed the revised version of the "conceptual inventory of natural selection" (CINS) questionnaire developed by Anderson et al. (2002), which can be downloaded from http://www.biologylessons.sdsu.edu/CINS6_03.pdf.sdsu.edu/CINS6_03.pdf
Sexual response was measured by the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire.
Treatment satisfaction of subjects and their female partners was assessed through responses to the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire.
Other secondary measures include the Behaviour Rating Inventory of Executive Function (BRIEF) questionnaire to be completed each by the parent and teacher [ 17].
