The Women's Health Questionnaire (WHQ): a psychometric evaluation of the 36-item Norwegian version.

Researchers in Norway evaluated a health questionnaire designed to measure symptoms women experience during menopause. The study was part of a larger clinical trial called ACUFLASH, which tested whether acupuncture could help reduce hot flashes and other menopausal symptoms.

The Women's Health Questionnaire (WHQ) contains 36 questions covering various aspects of women's health during menopause, including hot flashes, mood changes, sleep quality, and overall well-being. The researchers wanted to determine if this questionnaire was reliable and accurate when used with Norwegian women experiencing frequent hot flashes.

The study included 267 women who were having very frequent hot flashes. These women completed the questionnaire at the beginning of the acupuncture study. The researchers then analyzed the responses to see if the questionnaire was working properly.

What they found was that while the overall questionnaire score appeared reliable, there were some problems with specific sections. Some parts of the questionnaire didn't measure what they were supposed to measure very well, particularly the section about hot flashes and night sweats. The structure of the questionnaire wasn't as clear as expected, and some sections showed inconsistent results.

What this means for patients: If you're considering acupuncture for menopausal symptoms, this study reminds us that measuring treatment success can be challenging. While the research on acupuncture for hot flashes continues (this was just testing the questionnaire, not the treatment itself), it's important to track your symptoms in multiple ways, not just with questionnaires. Keep a detailed symptom diary and communicate openly with your healthcare provider about what you're experiencing. If considering acupuncture treatment, always seek care from a qualified, licensed acupuncturist with experience treating menopausal symptoms.

This psychometric study evaluated the 36-item Norwegian Women's Health Questionnaire (WHQ) using baseline data from the ACUFLASH randomized controlled trial examining acupuncture for menopausal hot flashes. The sample comprised 267 women experiencing high-frequency vasomotor symptoms.

Key methodological findings revealed significant psychometric limitations: unclear factor structure inconsistent with the original WHQ dimensions, low internal consistency (Cronbach's alpha) for several subscales, and substantial floor effects in the vasomotor symptoms dimension. While the total scale score demonstrated acceptable reliability, individual subscale interpretation requires caution.

Clinical takeaway: When assessing treatment outcomes for menopausal patients using the WHQ, practitioners should prioritize the total scale score over individual subscale scores, particularly the vasomotor dimension. Consider supplementing with objective measures (hot flash diaries, frequency counts) and alternative validated instruments. The psychometric weaknesses may be population-specific (women with severe, high-frequency symptoms) and could affect outcome measurement in clinical trials and practice-based assessments. Cross-cultural validation remains essential when adapting health instruments across populations.
