Parker MA, Kent AL, Sneddon A, et al. - Researchers conducted a cross-sectional study at three Senior High Schools in the Australian Capital Territory (ACT), Australia, with the aim to verify the value of the PIPPA (Period ImPact and Pain Assessment) self-screening tool for menstrual disturbance in teenagers. A total of 1,066 girls (aged between 15 and 19 years) underwent a quantitative paper survey that obtained self-reports of menstrual bleeding patterns, typical and atypical symptoms, morbidities and interference with daily activities. Using multiple correspondence analysis (MCA), associations between PIPPA questions were examined. Outcomes support the validity of PIPPA for pain related menstrual disturbance that affects functioning in young women. Good validity was recorded for PIPPA subdomains of pain/interference vs indicators of pain and interference and these subdomains are responsive to age, BMI and school absence differences. The indicator ‘missing school’ was highly linked with pain and interference, and correlation of both obesity (BMI ≥ 30) and underweight (BMI ≤ 18.4) with higher PIPPA scores was evident.
