Body image in idiopathic scoliosis: a comparison study of psychometric properties between four patient-reported outcome instruments.

ABSTRACT:

Background

Four patient-reported outcome (PRO) instruments are commonly used to assess body image in idiopathic scoliosis (IS): the Quality of Life Profile for Spinal Deformities (QLPSD), SRS-22 Self-Image scale, Spinal Appearance Questionnaire (SAQ), and Trunk Appearance Perception Scale (TAPS). The aim of this study is to compare the psychometric properties of these instruments in patients with IS and report the translational/cultural adaptation of the SAQ to Spanish.

Methods

The four instruments in a Spanish version were administered to 80 patients with IS aged 10 to 40 years old. The sample was stratified according to scoliosis magnitude (less and more than 45º). Analysis was also conducted for age groups. The psychometric properties studied included convergent and divergent construct validity, as well as internal consistency. Convergent validity was evaluated by correlation analysis between the self-image instruments and Cobb angle. Divergent validity was assessed with correlation analysis between PRO scores and SRS-22 dimensions scores such as Function, Pain and Mental Health.

Results

In the overall sample, each of the PRO instruments demonstrated high internal consistency (QLPSD Body Image, ??=?0.80; SRS-22 Self Image, ??=?0.78; SAQ, ??=?0.89; TAPS, ??=?0.87), also both for younger and adult patients subgroups. Correlation with curve magnitude was significant for each of the four scales. However, the correlation was higher for the pictorial scales (SAQ Appearance r?=?0.61, TAPS r?=?-0.62) than for the textual scales (QLPSD-bi r?=?0.36, SRS-22 Self-Image scale r?=?-0.41). In the younger group, correlation between Cobb angle and textual scales (QLPSD-bi and SRS-22 Self-Image Scale) was not significant. Body Image scales showed significant correlations with SRS-22 Pain, Function and Mental Health dimensions.

Conclusions

All four instruments tested have good psychometric properties. Pictorial scales (SAQ Appearance and TAPS) correlated better with the radiological magnitude of the curve and this correlation is independent of age. Unexpectedly, all four scales demonstrated significant correlations with non-body image dimensions and the divergent hypothesis was not confirmed. Globally, pictorial scales showed slightly better construct validity to test body image perception than textual scales.

Project description:BackgroundThe management of people living with HIV and AIDS is multidimensional and complex. Using patient-reported outcome measures (PROMs) has been increasingly recognized to be the key factor for providing patient-centered health care to meet the lifelong needs of people living with HIV and AIDS from diagnosis to death. However, there is currently no consensus on a PROM recommended for health care providers and researchers to assess health outcomes in people living with HIV and AIDS.ObjectiveThe purpose of this systematic review was to summarize and categorize the available validated HIV-specific PROMs in adults living with HIV and AIDS and to assess these PROMs using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology.MethodsThis systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of 3 recommended databases (PubMed, Embase, and PsychINFO) was conducted on January 15, 2021. Studies were included if they assessed any psychometric property of HIV-specific PROMs in adults living with HIV and AIDS and met the eligibility criteria. The PROMs were assessed for 9 psychometric properties, evaluated in each included study following the COSMIN methodology by assessing the following: the methodological quality assessed using the COSMIN risk of bias checklist; overall rating of results; level of evidence assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluation approach; and level of recommendation.ResultsA total of 88 PROMs classified into 8 categories, assessing the psychometric properties of PROMs for adults living with HIV and AIDS, were identified in 152 studies including 79,213 people living with HIV and AIDS. The psychometric properties of most included PROMs were rated with insufficient evidence. The PROMs that received class A recommendation were the Poz Quality of Life, HIV Symptom Index or Symptoms Distress Module of the Adult AIDS Clinical Trial Group, and People Living with HIV Resilience Scale. In addition, because of a lack of evidence, recommendations regarding use could not be made for most of the remaining assessed PROMs (received class B recommendation).ConclusionsThis systematic review recommends 3 PROMs to assess health outcomes in adults living with HIV and AIDS. However, all these PROMs have some shortcomings. In addition, most of the included PROMs do not have sufficient evidence for assessing their psychometric properties and require a more comprehensive validation of the psychometric properties in the future to provide more scientific evidence. Thus, our findings may provide a reference for the selection of high-quality HIV-specific PROMs by health care providers and researchers for clinical practice and research.

Project description:BackgroundThis study aimed to provide a German translation of the Body Image in Pregnancy Scale (BIPS) - a measure tailored to pregnancy-specific aspects of body image while being consistent to the multifaceted theoretical framework of body image - and to test its psychometric properties and validity.MethodsThe English-language original version of the BIPS was translated into German language using a forward-backward translation rationale. Face validity of the items was tested in cognitive interviews (n = 5). An online survey was conducted among 291 pregnant women. After conducting standard item analyses, factorial validity was tested using principal-axis factor analysis (PAF). Convergent and incremental validity with measures of body dissatisfaction (FFB), depression (EPDS), anxiety (GAD-7), self-esteem (RSE), and eating disorder psychopathology (EDE-Q) was tested by bivariate correlations and multiple linear hierarchical regression analyses.ResultsThe PFA revealed a 32 item and 6-factor solution resembling the dimensions preoccupation with appearance, dissatisfaction with strength-related aspects, dissatisfaction with body parts, dissatisfaction with complexion, prioritization of appearance over function, and concerns about sexual attractiveness. Internal consistency on a subscale level was good to excellent (.79 ≤ Cronbach's α ≤ .91). Consistent with theoretical assumptions, we found significant positive correlations of BIPS-G subscales with depression, anxiety and eating disorder psychopathology and negative correlations of BIPS-G subscales with self-esteem. BIPS-G subscales substantially improved the prediction of depression, anxiety, self-esteem and eating disorder psychopathology over demographic factors and body dissatisfaction (.03 ≤ ΔR2 ≤ .15, all p-values < 0.05).ConclusionsThe German version of the BIPS appeared to be a reliable and valid measure which has the capacity to enhance future research on body image during pregnancy in German-speaking populations.

Project description:BACKGROUND:Developing successful interventions for chronic musculoskeletal pain requires valid, responsive, and reliable outcome measures. The Minneapolis VA Evidence-based Synthesis Program completed a focused evidence review on key psychometric properties of 17 self-report measures of pain severity and pain-related functional impairment suitable for clinical research on chronic musculoskeletal pain. METHODS:Pain experts of the VA Pain Measurement Outcomes Workgroup identified 17 pain measures to undergo systematic review. In addition to a MEDLINE search on these 17 measures (1/2000-1/2017), we hand-searched (without publication date limits) the reference lists of all included studies, prior systematic reviews, and-when available-Web sites dedicated to each measure (PROSPERO registration CRD42017056610). Our primary outcome was the measure's minimal important difference (MID). Secondary outcomes included responsiveness, validity, and test-retest reliability. Outcomes were synthesized through evidence mapping and qualitative comparison. RESULTS:Of 1635 abstracts identified, 331 articles underwent full-text review, and 43 met inclusion criteria. Five measures (Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMDQ), SF-36 Bodily Pain Scale (SF-36 BPS), Numeric Rating Scale (NRS), and Visual Analog Scale (VAS)) had data reported on MID, responsiveness, validity, and test-retest reliability. Seven measures had data reported on three of the four psychometric outcomes. Eight measures had reported MIDs, though estimation methods differed substantially and often were not clinically anchored. CONCLUSIONS:In this focused evidence review, the most evidence on key psychometric properties in chronic musculoskeletal pain populations was found for the ODI, RMDQ, SF-36 BPS, NRS, and VAS. Key limitations in the field include substantial variation in methods of estimating psychometric properties, defining chronic musculoskeletal pain, and reporting patient demographics. TRIAL REGISTRATION:Registered in the PROSPERO database: CRD42017056610.

Project description:BackgroundSuboptimal health status (SHS) measurement has now been recognized as an essential construct in predictive, preventive, and personalized medicine. Currently, there are limited tools, and an ongoing debate about appropriate tools. Therefore, it is crucial to evaluate and generate conclusive evidence about the psychometric properties of available SHS tools.ObjectiveThis research aimed to identify and critically assess the psychometric properties of available SHS instruments and provide recommendations for their future use.MethodsArticles were retrieved by following the guidelines of the PRISMA checklist, and the robustness of methods and evidence about the measurement properties was assessed using the adapted COSMIN checklist. The review was registered in PROSPERO.ResultsThe systematic review identified 14 publications describing four subjective SHS measures with established psychometric properties; these included the Suboptimal Health Status Questionnaire-25 (SHSQ-25), Sub-health Measurement Scale Version 1.0 (SHMS V1.0), Multidimensional Sub-health Questionnaire of Adolescents (MSQA), and the Sub-Health Self-Rating Scale (SSS). Most studies were conducted in China and reported three reliability indices: (1) the internal consistency measured by Cronbach's α value ranged between 0.70 and 0.96; (2) the test-retest reliability; and (3) the split-half reliability coefficient values ranged between 0.64 and 0.98, and between 0.83 and 0.96, respectively. For the values of validity coefficients in the case of SHSQ-25 > 0.71, the SHMS-1.0 ranged from 0.64 to 0.87, and the SSS ranged from 0.74 to 0.96. Using these existing and well-characterized tools rather than constructing original tools is beneficial, given that the existing choice demonstrated sound psychometric properties and established norms.ConclusionsThe SHSQ-25 stood out as being more suitable for the general population and routine health surveys, because it is short and easy to complete. Therefore, there is a need to adapt this tool by translating it into other languages, including Arabic, and establishing norms based on populations from other regions of the world.

Project description:We aimed to provide a complex assessment of adult females with adolescent idiopathic scoliosis (AIS) after a minimum of 23 years after completed Milwaukee brace treatment. In the present study, a comparison between healthy female and AIS patients' perception of trunk disfigurement, self-image, mental health, pain level and everyday activity was made. Thirty AIS patients with a mean of 27.77 yrs (SD 3.30) after the treatment were included in the study. The control group consisted of 42 females, matching the age profile of the patient group. Study participants from both groups were examined using the same protocol, except for the radiological evaluation. Patients and healthy controls completed the Polish versions of the Scoliosis Research Society (SRS-22) and Spinal Appearance Questionnaire (SAQ). Patients additionally filled the Bad Sobberheim Stress Questionnaire-Deformity (BSSQ-Deformity) and Bad Sobberheim Stress Questionnaire-Brace (BSSQ-Brace). The study group's SAQ results differ significantly in regard to the total score and all individual domains, indicating better functioning among healthy controls. Except for the General domain (p = 0.002), among the remaining subscales the study group's results differed significantly at p<0.001. Considering SRS-22 results, it was revealed that the patient group scored higher, signaling better functioning with reference to pain level (p = 0.016), function/activity (p<0.001) and the total score (p<0.001). The findings add to the complexity of long-term effect evaluations of AIS, particularly amongst females treated with a Milwaukee brace. Long-term results were not conclusive in terms of nonverbal assessment of body image and emotional tension regarding the experiences of brace-wearing. Future patients can be reassured that scoliosis treated conservatively does not negatively affect everyday activity, pain level, childbearing and mental health. Subjects who declared to have psychological problems due to scoliosis had a bigger curve size after treatment and in this study than the other AIS patients.
