Table 2 Psychometric properties of the instruments and procedures
Examination procedure | Description of procedure | Indicator of musculoskeletal dysfunction | Reported psychometric properties |
|---|---|---|---|
Modified Oxford Scale (MOS) | Vaginal palpation performed by introduce of two fingers inside participant vaginal canal | Subjective evaluation of PFM function | Intra-rater reliability of MOS (Kappa test) [19] Bidigital palpation 0.75 Inter-rater reliability of MOS (Kappa test) Bidigital palpation 0.60 |
Manometry | PeritronTM manometer: insertion of a probe into the vaginal canal of participant | Objective evaluation of PFM function | Intra-rater reliability 0.96 [28] |
KHQ | Score variating 0 to 100 = the higher the score, the worse the quality of life | Impact of urinary loss | Internal consistency 0.87 [17] Reproducibility: evaluated by Pearson’s coefficient for all domains [29] (listed below): Perception of health 0.36 Impact of incontinence 0.60 Limitations of daily activities 0.75 Physical limitation 0.74 Social limitation personal relationship 0.82 Emotions 0.76 Sleep/energy 0.62 Severity measures 0.71 Minimum relevant clinical difference: 5 points [23] Responsiveness: evaluated by Cronbach’s alpha for all domains [30] (listed below): General health perception − 0.76 Impact of incontinence − 1.94 Role limitations − 1.50 Physical limitations − 1.49 Social limitations − 1.33 Personal relationships − 0.76 Emotions − 1.44 Sleep/energy − 0.86 Severity measures − 2.40 |
SF-6D | Score between 0 to 100 = the higher the score, the better the health status | Quality of life that constructed data about effectiveness, used in economic analyzes | Internal consistency: – Reproducibility intra-rater: evaluated by Pearson’s correlation coefficient for all domains [31] (listed below): Functional capacity 0.8 Physical aspects 0.63 Social aspects 0.75 Emotional aspects 0.44 Pain 0.54 Vitality 0.65 Mental health 0.69 General health status 0.84 Specificity: – Minimum relevant clinical difference: – Responsiveness: 0.404 (performed in women with postoperative pelvic organ prolapse; the value of the total score was used to identify the result of responsiveness through the ANOVA test) [32] |
King’s Health Questionnaire for Scoring Algorithm | Score: 0 = worst health status 1 = better health status | Health measures of UI | Internal consistency: – Reproducibility: – Specificity: – Minimizes relevant click difference: – Responsiveness: evaluated by standardized response mean (SRM) for all domains (listed below). The SRM is a version of the effect size that divides the mean change by the standard deviation of the change [27]: Role 0.56 Physical 0.51 Social 0.39 Personal 0.33 Emotions 0.37 Sleep 0.41 Severity 0.50 Valid: – |
