摘要
BACKGROUND/OBJECTIVES:Heavy menstrual bleeding (HMB) affects 34% to 37% of adolescent girls. The Menstrual Bleeding Questionnaire (MBQ) is a validated measure of menstrual bleeding-specific health-related quality of life (HRQoL) for women aged ≥18 years. No similar measure existed for adolescents with HMB. PATIENTS/METHODS:HMB was defined by the Pictorial Bleeding Assessment Chart (PBAC) score ≥100. In Phase 1, a focus group of adolescents with HMB adapted the MBQ, to generate the Adolescent MBQ (aMBQ). In phase 2, participants with and without HMB were recruited from clinics and self-referral. Each participant completed 3 questionnaires (aMBQ, Pediatric Quality of Life module [PedsQL]©, PBAC) at two time points. Validity of the aMBQ was assessed by Pearson's correlation with the PedsQL©. Reliability was calculated using intra-class correlation (ICC) in those without HMB. The receiver operating characteristic curve assessed the aMBQ's ability to identify those with HMB. RESULTS:Phase 1 included five girls with a mean age of 17.1 (13-18) years. The aMBQ was adapted from the MBQ by substituting four words/phrases that altered 8 of the 20 questions and by adding 1 new question. The 21-item aMBQ has a score range of 0 to 77 (77 = worst HRQoL). Phase 2 included 52 participants: 20 with and 32 without HMB, with a mean age of 14.8 (11-17) years. The validity of the aMBQ was confirmed by a moderate correlation with PedsQL© (r = -0.63; P < .001). Test-retest reliability was substantial (ICC = 0.73; P = .04). An aMBQ score of >30 identified those with HMB with excellent discrimination (area under the curve = 0.82; sensitivity, 70.0%; specificity, 84.4%). CONCLUSIONS:The aMBQ is a valid and reliable tool to assess HRQoL in adolescents with HMB.
