“…An explanation for this is that both pelvic girdle questionnaire and ODI are related to pain severity and its consequences. The assumption that pelvic girdle questionnaire is more sensitive and specific to consequences from PGP [13], was corroborated when the whole range of the scale was used in pelvic girdle questionnaire (0-93) as compared to ODI (0-64). In addition, the Swedish version of the pelvic girdle questionnaire showed no floor or ceiling effects, which strengthens its validity.…”

“…Previous studies have shown that self-reported PGP correlates well with clinically examined PGP, and we can thereby assume that the majority suffered from PGP [29,30]. In addition, pelvic girdle questionnaire is proposed as a suitable instrument for studies on LBP and PGP [13].…”

“…It is sensitive to severity levels of PGP, with an ability to discriminate between women during pregnancy vs. postpartum, as well as between different pain locations [12]. Furthermore, the pelvic girdle questionnaire has shown acceptable responsiveness in women with PGP, and has shown the ability to discriminate between participants who improved and those who did not [13]. The pelvic girdle questionnaire was recently recommended as the primary instrument for studies on LBP and PGP during pregnancy [14].…”

Purpose: The aims of this study were to translate and culturally adapt The Pelvic Girdle Questionnaire to Swedish, and to evaluate the construct and discriminative validity. Materials and methods: A translation and cultural adaptation process was performed according to international guidelines. Pilot tests were conducted among 16 women during pregnancy and post-partum. Analysis of the construct and discriminative validity of the Swedish version of the Pelvic Girdle Questionnaire was performed in a sample of 177 pregnant women suffering from pain in the lumbo-pelvic area. Participants completed the Pelvic Girdle Questionnaire along with Oswestry Disability Index, numeric rating scales for pain intensity and for pelvic girdle pain concerns. Results: The Swedish version of the Pelvic Girdle Questionnaire showed high internal consistency with Cronbach's alphas between 0.82 and 0.96, good convergent validity with high correlations with the Oswestry Disability Index and the pain intensity numeric rating scale, whereas moderate correlation was shown between the concerns numeric rating scale and the other instruments as hypothesized. Receiver operating characteristic curves showed good discriminatory capacity for women in need of treatment. Conclusions: The Swedish version of the Pelvic Girdle Questionnaire has patient acceptability. It has good construct and discriminative validity for measurements of consequences of pregnancy-related pelvic girdle pain among Swedish speaking women. ä IMPLICATIONS FOR REHABILITATIONPregnancy-related pelvic girdle pain may be disabling and long-lasting, however treatable when identified. The Pelvic Girdle Questionnaire is the only condition-specific, reliability tested and validated questionnaire for pelvic girdle pain. The Swedish version of the Pelvic Girdle Questionnaire has patient acceptability, good construct validity for pelvic girdle pain among Swedish speaking women, and shows good discriminative capacity for women in need of treatment.

“…In this study, we used ROC curves to examine cutoff values for the OMQ scale change scores (de Vet et al, 2006) The perceived improvement of movement quality on the GPE was used as an anchor (de Vet et al, 2011), which required the choice of a sensible cutoff point of important change (Stuge, Krogstad Jenssen, & Grotle, 2017). There is debate about whether the category 'a little improved' should be considered as change (de Vet et al, 2007;Demoulin, Ostelo, Knottnerus, & Smeets, 2010;Jaeschke et al, 1989;Wyrwich et al, 1999).…”

Aim: The Observable Movement Quality (OMQ) scale measures generic movement quality and is used alongside standardized ageadequate motor performance tests. The scale consists of 15 items, each focusing on a different aspect; together, the entire construct of movement quality is assessed. This study aimed to determine interrater and intrarater reliability, and responsiveness of the OMQ scale. Methods: A prospective intervention study with pre-post design in pediatric physical therapy practices. For interrater reliability, 3 physical therapists observed video-recorded motor assessments of 30 children with mild to moderate motor impairments-aged 4 to 12 years-using the OMQ scale. One therapist scored baseline assessment a second time for intrarater reliability, and to calculate smallest detectable change (SDC). Responsiveness (n ¼ 28) was tested by comparing outcomes before and after intervention. Results: Interrater reliability was moderate to good (ICC 2,1 : 0.79); intrarater reliability was high (ICC 2,1 : 0.97). Responsiveness results revealed an SDC of 2.4 and a minimal important change of 2.5; indicating sufficient validity in differentiating groups of children showing improved versus unchanged movement quality. Conclusion: The OMQ scale is reliable and responsive to change when used to assess movement quality in clinical practice for children with mild to moderate motor impairments, aged 4-12 year.

“…Correlations between PROM change scores and GRC scale scores were assessed by calculating Spearman's rank correlation coefficients. Correlation was interpreted as high (> 0·5), moderate (0·3–0·5) or low (< 0·3), based on previous studies and guidelines for assessing responsiveness . The next hypotheses (5, 6, 7) concerned the mean PROM change scores of improved, unchanged and worsened patients according to the associated GRC scale, namely the GRC scale measuring a similar construct.…”

Responsiveness of quality‐of‐life measures in patients with peripheral vascular malformations: the OVAMA project

Summary Background The OVAMA (Outcome Measures for Vascular Malformations) project determined quality of life (QoL) as a core outcome domain for patients with vascular malformations. In order to measure how current therapeutic strategies alter QoL in these patients, a patient‐reported outcome measurement (PROM) responsive to changes in QoL is required. Objectives To assess the responsiveness of two widely used generic QoL PROMs, the Medical Outcomes Study Short Form 36 (SF‐36) and Skindex‐29, in adult patients with vascular malformations. Methods In an international multicentre prospective study, treated and untreated patients completed the SF‐36 and Skindex‐29 at baseline and after a follow‐up period of 6–8 weeks. Global rating of change (GRC) scales assessing various QoL‐related outcome domains were additionally completed. Per subscale, responsiveness was assessed using two methods: by testing hypotheses on expected correlation strength between change scores of the questionnaires and the GRC scales, and by calculating the area under the receiver operating characteristics curve (AUC). The questionnaires were considered responsive if ≥ 75% of the hypotheses were confirmed or if the AUC was ≥ 0·7. Results Eighty‐nine participants were recruited in three centres in the Netherlands and the U.S.A., of whom 67 completed all baseline and follow‐up questionnaires. For all subscales of the SF‐36 and Skindex‐29, < 75% of the hypotheses were confirmed and the AUC was < 0·7. Conclusions Our findings suggest that the SF‐36 and Skindex‐29 seemed unresponsive to change in QoL. This suggests that alternative PROMs are needed to measure – and ultimately improve – QoL in patients with vascular malformations. What's already known about this topic? Quality of life is often impaired in patients with vascular malformations. Quality of life is considered a core outcome domain for evaluating treatment of vascular malformations. To measure the effect of treatment on quality of life, a patient‐reported outcome measure is required that is responsive to changes in quality of life. What does this study add? This is the first study assessing the responsiveness of quality‐of‐life measures in patients with vascular malformations. The results seem to indicate that the Medical Outcomes Study Short Form 36 (SF‐36) and Skindex‐29 are not responsive to changes in quality of life in patients with vascular malformations. What are the clinical implications of this work? Medical Outcomes Study Short Form 36 (SF‐36) and Skindex‐29 are not ideal to assess the effect on quality of life over time, of treatment strategies for peripheral vascular malformations.
