Measuring self-esteem after spinal cord injury: Development, validation and psychometric characteristics of the SCI-QOL Self-esteem item bank and short form

The Association Between Spirituality, Self-Esteem, Anxiety and Depression: A Comparative Exploratory Study Between People with a Spinal Cord Injury and Healthy Subjects in Greece

The purpose of this study was to evaluate spirituality, religiosity, self-esteem, depression, and stress in people with spinal cord injuries. The Royal Free Questionnaire for Spiritual and Religious Beliefs, the Rosenberg Self-Esteem Scale, the Center for Epidemiologic Studies Depression Scale, and the Spielberger State-Trait Anxiety Scale were all designed for the current study to collect demographic and injury-related information. In the study, 88 patients with traumatic SCI and 88 healthy subjects were included. Half of the participants and healthy subjects were women, while the mean age of the healthy subjects was 42.8 years and that of the subjects was 42.4 years. The majority of participants were Greek (97.2%), while 44.1% were married or with a partner and 43.2% were single. The mean depression and stress score was higher in patients than in healthy subjects, and the mean score of self-esteem was lower in patients than healthy subjects. Multivariable linear regression model showed that patients who believed more that a spiritual force or power outside of ourselves can influence what happens in everyday life had less depression and stress. People with spinal cord injuries experience extreme stress, anxiety, and depression. Spirituality and religiosity can play a significant role in their recuperation, rehabilitation, and adaptation.

Baseline Comparison of Exercisers and Nonexercisers With Spinal Cord Injury Enrolled in a Group Tele-Exercise Program

Background

Individuals with SCI are 1.5 times more likely to be sedentary compared to adults without disabilities or chronic health conditions. It is therefore imperative to develop and evaluate innovative facilitation strategies for physical activity behavior in this population.

Objectives

As an insightful step to creating and evaluating tailored physical activity interventions for individuals with SCI, we evaluated demographic, psychosocial, and physical characteristics of those who choose to engage in physical activity by enrolling in a group exercise study.

Design/Methods

We conducted a cross-sectional analysis detailing demographic features and baseline outcomes of those with SCI enrolled in a group tele-exercise study who were classified as regular exercisers versus nonregular exercisers per the American College of Sports Medicine exercise guidelines. Between-group differences for psychosocial and physical outcomes were assessed with chi-square and Mann-Whitney U tests (p < .05).

Results

Twenty-seven adult volunteers enrolled in the study (exercisers = 14, nonexercisers = 13). Groups were comparable for biological sex, gender identity, self-reported racial group(s), and current age. Exercisers demonstrated significantly shorter duration of injury compared to nonexercisers (p = .012). Exercisers exhibited significantly higher exercise self-efficacy (p = .017) and increased reported weekly minutes in vigorous intensity leisure time physical activity (p = .029).

Conclusion

Nonexercisers with SCI demonstrate increased injury duration and reduced exercise self-efficacy compared to active peers. These factors should be addressed in the design and delivery of SCI-specific physical activity interventions to increase the likelihood of this critical health behavior over time.

Neurological Health: Not Merely the Absence of Disease: Current Wellbeing Instruments Across the Spectrum of Neurology

OBJECTIVE

Well-being and quality of life can vary independently of disease. Instruments measuring well-being and quality of life are commonly used in neurology, but there has been little investigation into the extent in which they accurately measure wellbeing/quality of life or if they merely reflect a diseased state of an individual.

DESIGN

Systematic searches, thematic analysis and narrative synthesis were undertaken. Individual items from instruments represented in ≥ 5 publications were categorised independently, without prior training, by five neurologists and one well-being researcher, as relating to 'disease-effect' or 'Well-being' with a study-created instrument. Items were additionally categorised into well-being domains.

DATA SOURCES

MEDLINE, EMBASE, EMCARE and PsycINFO from 1990 to 2020 were performed, across the 13 most prevalent neurological diseases.

RESULTS

301 unique instruments were identified. Multiple sclerosis had most unique instruments at 92. SF-36 was used most, in 66 studies. 22 instruments appeared in ≥ 5 publications: 19/22 'well-being' outcome instruments predominantly measured disease effect (Fleiss kappa = .60). Only 1/22 instruments was categorised unanimously as relating to well-being. Instruments predominantly measured mental, physical and activity domains, over social or spiritual.

CONCLUSIONS

Most neurological well-being or quality-of-life instruments predominantly measure disease effect, rather than disease-independent well-being. Instruments differed widely in well-being domains examined.

Assessment of quality of life after upper extremity transplantation: Framework for patient-reported outcome scale domains

Upper extremity transplantation offers the promise of restored function and regained quality of life (QOL) for individuals who have sustained hand or arm amputation. However, a major challenge for this procedure becoming an accessible treatment option for patients is the lack of standard measures to document benefits to QOL. Patient-reported outcomes (PRO) measures are well-suited for this kind of intervention, where the perspective of the patient is central to defining treatment success. To date, qualitative work with experts, clinicians, and patients has been used to identify the most important domains of QOL for PRO item development. Specifically, our group's qualitative work has identified several domains of QOL that are unique to individuals who have received upper extremity transplants, which are distinct from topics covered by existing PRO measures. These include emotional and social aspects of upper extremity transplant, such as Expectations and Perceived Outcomes, Integration and Assimilation of Transplant, Fitting in, and Post-Surgical Challenges and Complications. The broad topic of Satisfaction with Transplant was subdivided into three subtopics: Function, Sensation, and Aesthetics. Satisfaction with Sensation was also identified as a unique domain not evaluated by existing PRO measures. This report operationalizes these eight QOL domains by presenting scoping definitions. This manuscript describes the work that has been completed for domain characterization as an early step toward developing standardized PRO measures to evaluate these important outcomes specific to upper extremity transplantation.

A Study Protocol for a Multisite Randomized Controlled Trial of an Intervention to Improve Outcomes After Spinal Cord Injury

Background

The consequences of spinal cord injury (SCI) can place significant demands on an individual's coping mechanisms. Interventions to promote psychological adjustment and coping are often included in inpatient rehabilitation programs; however, following discharge, many individuals with SCI do not receive ongoing counseling or education about psychological adjustment to disability. Effective postacute treatment models are needed to help individuals with SCI build skills that help them adapt to the stresses associated with a chronic physical disability, alleviate the consequences of anxiety and depression, and enhance subjective well-being.

Objectives

To describe the protocol for a randomized clinical trial (RCT) of a 6-week intervention designed to improve psychosocial outcomes after SCI.

Methods

To test efficacy and replicability of the intervention, we designed a three-arm, multisite RCT with assessments conducted at six time points. Our primary hypothesis is that participants in the Group arm will report greater improvements in psychosocial outcomes than participants who complete the intervention individually via video (Individual arm) or those who do not receive the intervention (Control arm). We also hypothesize that participants in the Group arm will maintain greater improvements in psychosocial outcomes longer than those in the individual or control arms.

Conclusion

Results of the RCT will be presented and published to professionals and consumers, and intervention training and materials will be made available upon request.

Applicability of the AO Spine Patient Reported Outcome Spine Trauma (PROST) in people with motor-complete spinal cord injury: a cognitive interview study

STUDY DESIGN

This is a cognitive interview study.

OBJECTIVES

To examine the applicability of the Patient Reported Outcome Spine Trauma (AO Spine PROST) in people with motor-complete traumatic or non-traumatic spinal cord injury (SCI).

SETTING

Two rehabilitation centers in The Netherlands.

METHOD

Semi-structured cognitive interviews were conducted with 29 adults with a motor-complete SCI (AISA Impairment Scale A or B). Participants were asked to complete the AO Spine PROST and four additional evaluation questions rated on a 1-5-point Likert scale (5 most positive), while verbalizing their thoughts about their answers. Interviews were audio-recorded and transcribed. Codes were identified and linked to a coding scheme. Qualitative data were used to interpret the quantitative results.

RESULTS

Almost three-quarters of the participants (71.4%) had a traumatic SCI. Positive ratings of the measure were obtained regards comprehensibility (mean 4.0), non-offensiveness (4.6), relevance (4.2), and completeness (3.6). A question about the emotional impact of SCI was indicated to be missing. How using an assistive device should weigh in the score was a recurring topic. The use of multiple examples per item raised uncertainty, mostly solved by averaging their score. Some individuals indicated that the possibility to express even better function compared to before the onset of injury would be valuable.

CONCLUSIONS

Overall, the AO Spine PROST appears applicable in adults with a motor-complete traumatic or non-traumatic SCI. Recommendations are made for improvement in instructions, terminology, and examples used in the tool. This study contributes to the further development of the AO Spine PROST in spine trauma care and research.

Dutch-Flemish translation and cross-cultural adaption of the Spinal Cord Injury-Quality of Life (SCI-QOL) short forms

PURPOSE

A spinal cord injury (SCI) has a large impact on a person's physical, psychological, and social health. Previous studies focused on physical recovery in patients with SCI and assessed their health-related quality of life (HRQOL) with general questionnaires, which often contain irrelevant questions. The SCI-QOL questionnaire was developed to specifically assess the HRQOL of the SCI population. A comprehensive translation and cross-cultural adaptation are required to use this questionnaire in the Netherlands and Flanders, Belgium.

METHODS

All 23 short forms of the SCI-QOL for adults were translated from English into Dutch-Flemish using the Functional Assessment of Chronic Illness Therapy translation methodology, with a cognitive debriefing being performed with 10 patients with SCI and 10 persons from the general population.

RESULTS

The Dutch-Flemish PROMIS group previously translated 46 of the 207 items in the 23 short forms. Here, we achieved an acceptable translation of the other 161 items. A single Dutch-Flemish translation was obtained for 20 short forms, while separate Dutch and Flemish translations were necessary for the short forms Ambulation, Manual Wheelchair, and Stigma.

CONCLUSION

The Dutch-Flemish translation of the SCI-QOL is now available for clinical and research purposes. Future studies should focus on the psychometric properties of this cross-culturally adapted version.

Overview of the Spinal Cord Injury-Functional Index (SCI-FI): Structure and Recent Advances

The Spinal Cord Injury - Functional Index is a system of patient reported outcomes (PRO) measures of functional activities developed specifically with and for individuals with spinal cord injury (SCI). The SCI-FI was designed to overcome limitations in measurement of the full range of activities and breadth of content of physical functioning commonly used in SCI research. Generic measurement tools of physical function (i.e., those focused on the general population) tend to overemphasize mobility and do not contain enough items at the lower end of the functional range (e.g., appropriate for individuals with tetraplegia). The SCI-FI consists of nine item response theory (IRT)-calibrated item banks that represent relevant and meaningful item content for individuals with SCI, span a wide range of functional abilities, and subdivide physical functioning into important subdomains, including basic mobility, self-care, and fine motor function. Since the original publication of the SCI-FI in 2012, there have been significant advances in and publications on the reliability and psychometric properties of the measures. The manuscripts presented in this special section clarify the SCI-FI structure and present new research on the SCI-FI measurement system.

Measuring pain phenomena after spinal cord injury: Development and psychometric properties of the SCI-QOL Pain Interference and Pain Behavior assessment tools

OBJECTIVE

To develop modern patient-reported outcome measures that assess pain interference and pain behavior after spinal cord injury (SCI).

DESIGN

Grounded-theory based qualitative item development; large-scale item calibration field-testing; confirmatory factor analyses; graded response model item response theory analyses; statistical linking techniques to transform scores to the Patient Reported Outcome Measurement Information System (PROMIS) metric.

SETTING

Five SCI Model Systems centers and one Department of Veterans Affairs medical center in the United States.

PARTICIPANTS

Adults with traumatic SCI.

INTERVENTIONS

N/A.

OUTCOME MEASURES

Spinal Cord Injury - Quality of Life (SCI-QOL) Pain Interference item bank, SCI-QOL Pain Interference short form, and SCI-QOL Pain Behavior scale.

RESULTS

Seven hundred fifty-seven individuals with traumatic SCI completed 58 items addressing various aspects of pain. Items were then separated by whether they assessed pain interference or pain behavior, and poorly functioning items were removed. Confirmatory factor analyses confirmed that each set of items was unidimensional, and item response theory analyses were used to estimate slopes and thresholds for the items. Ultimately, 7 items (4 from PROMIS) comprised the Pain Behavior scale and 25 items (18 from PROMIS) comprised the Pain Interference item bank. Ten of these 25 items were selected to form the Pain Interference short form.

CONCLUSIONS

The SCI-QOL Pain Interference item bank and the SCI-QOL Pain Behavior scale demonstrated robust psychometric properties. The Pain Interference item bank is available as a computer adaptive test or short form for research and clinical applications, and scores are transformed to the PROMIS metric.

Measuring stigma after spinal cord injury: Development and psychometric characteristics of the SCI-QOL Stigma item bank and short form

OBJECTIVE

To develop a calibrated item bank and computer adaptive test (CAT) to assess the effects of stigma on health-related quality of life in individuals with spinal cord injury (SCI).

DESIGN

Grounded-theory based qualitative item development methods, large-scale item calibration field testing, confirmatory factor analysis, and item response theory (IRT)-based psychometric analyses.

SETTING

Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States.

PARTICIPANTS

Adults with traumatic SCI.

MAIN OUTCOME MEASURES

SCI-QOL Stigma Item Bank

RESULTS

A sample of 611 individuals with traumatic SCI completed 30 items assessing SCI-related stigma. After 7 items were iteratively removed, factor analyses confirmed a unidimensional pool of items. Graded Response Model IRT analyses were used to estimate slopes and thresholds for the final 23 items.

CONCLUSIONS

The SCI-QOL Stigma item bank is unique not only in the assessment of SCI-related stigma but also in the inclusion of individuals with SCI in all phases of its development. Use of confirmatory factor analytic and IRT methods provide flexibility and precision of measurement. The item bank may be administered as a CAT or as a 10-item fixed-length short form and can be used for research and clinical applications.

Kalpakjian C, W. Choi S, Jette AM, Forchheimer M, Cella D. Overview of the Spinal Cord Injury--Quality of Life (SCI-QOL) measurement system

CONTEXT/OBJECTIVE

The Spinal Cord Injury--Quality of Life (SCI-QOL) measurement system was developed to address the shortage of relevant and psychometrically sound patient reported outcome (PRO) measures available for clinical care and research in spinal cord injury (SCI) rehabilitation. Using a computer adaptive testing (CAT) approach, the SCI-QOL builds on the Patient Reported Outcomes Measurement Information System (PROMIS) and the Quality of Life in Neurological Disorders (Neuro-QOL) initiative. This initial manuscript introduces the background and development of the SCI-QOL measurement system. Greater detail is presented in the additional manuscripts of this special issue.

DESIGN

Classical and contemporary test development methodologies were employed. Qualitative input was obtained from individuals with SCI and clinicians through interviews, focus groups, and cognitive debriefing. Item pools were field tested in a multi-site sample (n=877) and calibrated using item response theory methods. Initial reliability and validity testing was performed in a new sample of individuals with traumatic SCI (n=245).

SETTING

Five Model SCI System centers and one Department of Veterans Affairs Medical Center across the United States.

PARTICIPANTS

Adults with traumatic SCI.

INTERVENTIONS

OUTCOME MEASURES

n/a

RESULTS

The SCI-QOL consists of 19 item banks, including the SCI-Functional Index banks, and 3 fixed-length scales measuring physical, emotional, and social aspects of health-related QOL (HRQOL).

CONCLUSION

The SCI-QOL measurement system consists of psychometrically sound measures for individuals with SCI. The manuscripts in this special issue provide evidence of the reliability and initial validity of this measurement system. The SCI-QOL also links to other measures designed for a general medical population.

Methodology for the development and calibration of the SCI-QOL item banks

OBJECTIVE

To develop a comprehensive, psychometrically sound, and conceptually grounded patient reported outcomes (PRO) measurement system for individuals with spinal cord injury (SCI).

METHODS

Individual interviews (n=44) and focus groups (n=65 individuals with SCI and n=42 SCI clinicians) were used to select key domains for inclusion and to develop PRO items. Verbatim items from other cutting-edge measurement systems (i.e. PROMIS, Neuro-QOL) were included to facilitate linkage and cross-population comparison. Items were field tested in a large sample of individuals with traumatic SCI (n=877). Dimensionality was assessed with confirmatory factor analysis. Local item dependence and differential item functioning were assessed, and items were calibrated using the item response theory (IRT) graded response model. Finally, computer adaptive tests (CATs) and short forms were administered in a new sample (n=245) to assess test-retest reliability and stability.

PARTICIPANTS AND PROCEDURES

A calibration sample of 877 individuals with traumatic SCI across five SCI Model Systems sites and one Department of Veterans Affairs medical center completed SCI-QOL items in interview format.

RESULTS

We developed 14 unidimensional calibrated item banks and 3 calibrated scales across physical, emotional, and social health domains. When combined with the five Spinal Cord Injury--Functional Index physical function banks, the final SCI-QOL system consists of 22 IRT-calibrated item banks/scales. Item banks may be administered as CATs or short forms. Scales may be administered in a fixed-length format only.

CONCLUSIONS

The SCI-QOL measurement system provides SCI researchers and clinicians with a comprehensive, relevant and psychometrically robust system for measurement of physical-medical, physical-functional, emotional, and social outcomes. All SCI-QOL instruments are freely available on Assessment CenterSM.
