Validation of the Italian version of the Spinal Cord Independence Measure (SCIM III) Self-Report

Translation and validation of the Chinese self-report version of Spinal Cord Independence Measure (SCIM-SR): Rasch psychometric analysis and online application

Spinal Cord Independence Measure (SCIM) was an important functional outcome measure specifically designed for spinal cord injury (SCI) patients, with the self-reported version of SCIM (SCIM-SR) published in 2013. This study aims to translate the SCIM-SR into Chinese, and to investigate the validity of Chinese SCIM-SR among SCI patients. This Chinese version of SCIM-SR was translated into Chinese in a standardized approach, and then filled out by a sample of patients with SCI (n = 205) within 3 days after admission. Validity of Chinese SCIM-SR was then analyzed using Rasch analysis and principal component analysis. The subscale Selfcare and subscale Mobility showed good fit to the Rasch model, with no significance found in Chi-square test results for item-trait interaction, using Bonferroni adjustment for the significant level (χ2 =18.125, P = 0.111; χ2 =33.629, P = 0.006). Mean fit residual for items and persons of each subscale were within ± 2.5. The model fit of the subscale of Respiration and Sphincter Management was not satisfactory even after deleting one item and merging two items with local dependence. However, Kaiser-Meyer-Olkin test was > 0.50 in total score and all the subscales of Chinese SCIM-SR, and P < 0.05 in the Bartlett's test. There was no differential item functioning for gender, time post injury, age, and etiology in any of the three subscales. An online version of Chinese SCIM-SR was also developed. It is concluded that the SCIM-SR in Chinese is valid for application in individuals with SCI. SCIM-SR is considered as an important tool for self-reporting functional status from SCI individuals' perspective.

Reliability of the Nepali Version of the Spinal Cord Independence Measure Self-Report

A self-report measure is considered a practical alternative tool for longitudinal monitoring and for community models of disability. Spinal Cord Independence Measure Self-Report (SCIM-SR) was developed to measure the functional independence of the spinal cord injury (SCI) population. For the application of this questionnaire in Nepali setting, the cross-cultural adaptation and reliability of the Nepali version of the SCIM-SR were also warranted. The aim of the study was to cross-culturally adapt the Nepali version of the SCIM-SR and determine its reliability. The English version of the SCIM-SR was translated into the Nepali language with cross-cultural adaptations following the Beaton guidelines. A total of 45 community-dwelling individuals with SCI administered the Nepali version of the SCIM-SR two times, with an interval of one week. The intraclass correlation coefficient (ICC) and Cronbach's alpha (α) were used to assess the test-retest reliability and internal consistency, respectively. Cross-cultural equivalence was achieved between the English version and the Nepali version of the SCIM-SR. The test-retest reliability was excellent, with ICCs for the total score 0.968 (95% confidence interval 0.941–0.982), self-care subscale 0.964 (0.934–0.980), respiration and sphincter management subscale 0.941 (0.893–0.968), and mobility subscale 0.966 (0.938–0.981). The internal consistency reached an acceptable range for the total score and most of the subscales except for those of respiration and sphincter management. Cronbach's α coefficients for the total score, self-care subscale, respiration and sphincter management subscale, and mobility subscale were 0.801, 0.959, 0.506, and 0.838, respectively. The Nepali version of the SCIM-SR was cross-culturally adapted and can be used as a reliable self-report instrument to assess functional independence among the community-dwelling SCI population in Nepal.

Functional independence in the Finnish spinal cord injury population

Study design

A cross-sectional survey of the Finnish population with spinal cord injury (FinSCI database).

Objectives

To describe the functional independence of the population with spinal cord injury (SCI) in Finland and to identify how generic and lesion characteristics affect their functional independence.

Setting

The participants were recruited from the registers of three SCI outpatient clinics responsible for lifelong follow-up and care for people with SCI in Finland.

Methods

The data were retrieved from FinSCI (n = 1772). The response rate was 50% (n = 884). The Spinal Cord Independence Measure-Self Report (SCIM-SR) was used. The data were analyzed with univariate testing, factor analyses, and multiple linear regression models.

Results

The median (percentiles 25; 75) SCIM-SR total score was 76.0 (58.8; 89.0), and the score was 18.0 (13.0; 20:0) for the self-care sub-scale, 33.0 (25.0; 39.0) for the respiration and sphincter management sub-scale and 29.0 (16.0; 36.8) for the mobility sub-scale. The higher the neurological level in groups AIS A, B, and C, the lower the functional ability. Group AIS D at any injury level had the highest level of functional ability. Age and the number of years since injury negatively influenced the SCIM-SR scores for every sub-scale.

Conclusion

Based on the International Spinal Cord Injury Core Data Set, the severity of SCI can differentiate persons with SCI according to their functional ability. The results suggest that SCI affects individuals’ health more than ageing alone does, thereby reducing the functional ability and independence of persons with SCI over time.

Adaptation and validation of the Japanese version of the Spinal Cord Independence Measure (SCIM III) self-report

STUDY DESIGN

Psychometric study, cross-sectional validation study.

OBJECTIVES

To adapt and validate the Japanese version of the Spinal Cord Independence Measure self-report (SCIM-SR).

SETTING

A spinal cord injury (SCI) rehabilitation facility in Japan.

METHODS

We adapted the SCIM-SR for the Japanese population by translating and validating the questionnaire in accordance with the international guidelines. Following this, we analyzed 100 inpatients with SCI. We evaluated their independence using the Japanese SCIM-SR, and compared the data with those assessed using the SCIM III by trained ward nurses.

RESULTS

Spearman's rank correlation coefficients were 0.95 for the total score, 0.89 for self-care, 0.83 for respiration and sphincter management, and 0.89 for mobility subscores. The Bland-Altman analysis revealed no significant proportional bias (-0.02; 95% CI [-0.07, 0.06]), but a significant fixed bias (2; 95% CI [0.5, 3.5]). We did not identify any specific factor that affected the differences between SCIM III and SCIM-SR scores.

CONCLUSIONS

Our study validated the Japanese version of SCIM-SR as a tool for the evaluation of the independence of persons with SCI, which could substitute SCIM III and help facilitate a deeper understanding of activities of daily living among patients with SCI.

Association between sleep quality and participation in people with spinal cord injury: A preliminary study

OBJECTIVE

To explore the association between perceived sleep quality and participation in people with spinal cord injury (SCI).

DESIGN

Cross-sectional study.

SETTING

Spinal unit at the Città della Salute e della Scienza University Hospital of Turin, Italy.

PARTICIPANTS

From May to July 2019, 55 consecutive outpatients were recruited.

OUTCOME MEASURES

A set of structured questionnaires was administered. It included sociodemographic data, the Pittsburgh Sleep Quality Index, the Utrecht Scale for Evaluation of Rehabilitation-Participation, the Spinal Cord Independence Measure Self-Report, the Short Form version 12.2, and the Hospital Anxiety and Depression Scale. T-tests were used to highlight differences between participation and participant characteristics. Bivariate analyses and linear regressions were performed to identify associations between sleep quality and participation.

RESULTS

Differences in participation occurred mainly in individuals with a higher level of injury, caregiver dependency, and lower functional level. Participants reporting better sleep quality had more frequent (r = -0.36, P < 0.01), less restricted (r = -0.32, P < 0.05), and more satisfactory participation (r = -0.33, P < 0.01). Linear regression analyses showed that poor sleep quality was significantly associated with reduced participation frequency (β = -0.30, P = 0.03) and less satisfaction with participation (β = -0.49, P < 0.001). Moreover, age, number of hours slept at night, and time since injury were associated with satisfaction with participation.

CONCLUSIONS

An association was found between sleep quality and participation in people with SCI. Given the high prevalence of sleep problems and their association with all dimensions of participation, the promotion of sleep quality should be encouraged because it may positively affect participation.

Translation and validation of the Chinese version of the Spinal Cord Independence Measure (SCIM III) Self-Report

STUDY DESIGN

A cross-sectional psychometric study.

OBJECTIVE

To translate, culturally adapt and validate the Chinese version of the Spinal Cord Independence Measure III-Self Report (SCIM-SR).

SETTING

Four rehabilitation centers in Guangzhou, Chengdu, and Shiyan, China.

METHODS

Translation and cultural adaptation of the Chinese version of the SCIM-SR was conducted according to Brislin guidelines. A total of 147 spinal cord injury patients self-rated their functional independence using translated instrument. The psychometric properties of content validity, criterion-related validity, internal consistency reliability, and test-retest reliability were examined.

RESULTS

The content validity index of the new scale was 0.99. The intraclass correlation coefficient between the total SCIM-SR and SCIM III scores was 0.935, and the coefficients for its three subscales were 0.899, 0.760, and 0.942. Bland-Altman analysis showed that the mean difference between the total SCIM-SR and SCIM III scores was 2.35 (95% confidence interval -0.58 to 5.28), and differences for the three subscales were 0.75 (-0.51-2.01), 1.30 (-0.63-3.23), and 0.30 (-0.80-1.40). The Cronbach's α coefficients for the total scale, the self-care subscale, and the mobility subscale were 0.908, 0.913, and 0.895, respectively. The α for the respiration and sphincter management subscale was 0.581. Test-retest reliability after 2 weeks yielded a Spearman coefficient for the total scale of and subscale values all above 0.73.

CONCLUSIONS

Our results indicate acceptable validity and reliability of the Chinese version of SCIM-SR. It may facilitate long-term evaluations of independence in Chinese spinal cord injury patients in the community and at home.

Cross-cultural adaptation and psychometric testing of the Thai version of the Spinal Cord Independence Measure III-Self Report

STUDY DESIGN

Cross-sectional reliability and validation study.

OBJECTIVE

To translate and assess the psychometric properties of the Thai version of the Spinal Cord Independence Measure III-Self Report (TH-SCIM-SR) in Thai spinal cord injury (SCI) patients.

SETTING

Faculty of Medicine Siriraj Hospital, Mahidol University.

METHODS

A cross-cultural forward and backward translation of the original Spinal Cord Independence Measure III-Self Report (SCIM-SR) was performed at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand, to create the TH-SCIM-SR. The inclusion criteria were Thai patients with SCI duration of ≥3 months. Patients were evaluated by a team of healthcare professionals using the Thai version of the Spinal Cord Independence Measure Version III (TH-SCIM III). Study patients subsequently completed the TH-SCIM-SR two times with a 3-day interval between evaluations. Cronbach's Alpha, Pearson's correlation coefficient, and intraclass correlation coefficient (ICC) were used to examine internal consistency, concurrent validity, and reliability, respectively. Bland-Altman plot was used to compare scoring results between the TH-SCIM III and the TH-SCIM-SR.

RESULTS

Thirty-two patients were included. Cronbach's alpha of total score, self-care subscale, respiration/sphincter management, and mobility subscale were 0.91, 0.94, 0.75, and 0.90, respectively. The reliability analysis showed good reliability. The test-retest ICC of total score, self-care subscale, respiration/sphincter management, and mobility subscale were 0.95, 0.95, 0.78, and 0.96, respectively. Regarding construct validity, the subscales of TH-SCIM-SR demonstrated a strong correlation with those of the TH-SCIM III (0.85-0.96).

CONCLUSIONS

TH-SCIM-SR showed good reliability and validity for assessing functional independence in Thai patients with SCI.

The Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15): validation of the Italian version for individuals with spinal cord injury

STUDY DESIGN

Psychometric study.

OBJECTIVE

The aim of the study was to translate and culturally adapt the MSISQ-15 into Italian and to administer it to individuals with a spinal cord injury (SCI).

SETTING

Rome's Wheelchair Rugby Team and three spinal units in Italy.

METHODS

Translation and validation of the MSISQ-15 were performed based on international guidelines. The questionnaire, which was in a paper and online format, was administered with the Short Form-12 Health Survey (SF-12) and the Spinal Cord Independence Measure Self-Report.

RESULTS

Sixty-five participants were recruited. Internal consistency coefficient of MSISQ-15 scale, assessed by Cronbach's alpha, was 0.75. Test-retest reliability interclass correlations was, for example, 0.86. The construct validity was calculated and showed statistically significant results in relation to the mental health status investigated with the SF-12.

CONCLUSIONS

The MSISQ-15 is a valid, reliable, and useful questionnaire for investigating how often the symptoms of an SCI interfere with a person's satisfaction or sexual activity.

The Relationship Between Psychological and Physical Secondary Conditions and Family Caregiver Burden in Spinal Cord Injury: A Correlational Study

Background: Caregiver burden (CB) is a consequence of providing care to people with spinal cord injury (SCI). However, there is a lack of clarity about the influence of secondary conditions of care recipients on family caregivers. Secondary conditions refer to the physical and psychological complications that can occur after SCI and lead to increased hospitalization and reduced functionality, quality of life, and social participation. Objective: To assess the impact of physical and psychological secondary conditions of people with SCI on the perceived burden of family caregivers. Methods: A multicenter, cross-sectional study of 56 dyads of family caregivers and individuals with SCI in two urban spinal units in Italy and Ireland. Care recipients completed a toolset consisting of demographic information and assessments of functional, physical, and psychological health. Caregivers completed a multidimensional measure of CB. Bivariate data analysis was used. Results: No significant differences between centers were identified. CB was found to be related to physical secondary conditions and functional independence but not to mental health of care recipients. Bladder dysfunction and urinary tract infections influenced all dimensions of CB, whereas pressure injuries influenced only the time-dependent dimension. Level and completeness of injury and duration of caregiving increased CB. Conclusion: Findings indicate the value of a reduction in secondary conditions not just for individuals with SCI but also for their family caregivers. To reduce the individual and family burden of secondary conditions, a two-pronged, multidimensional approach, focusing on self-management for care recipients and psychoeducational support for caregivers, is required.

Lack of knowledge and training are the major obstacles in application of the Spinal Cord Independence Measure (SCIM) in China

OBJECTIVE

To investigate the use of functional outcome measurements after spinal cord injury (SCI) in current clinical practice and to explore the knowledge about the Spinal Cord Independence Measure (SCIM) among SCI physicians in China, and to find facilitators for a broader utilization of SCIM.

DESIGN

A survey-based study.

SETTING

SCI workshops at Peking University.

PARTICIPANTS

125 Chinese SCI physicians attending annual workshops in two consecutive years.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

A questionnaire was administered. The following items were included: whether functional outcome measurement for SCI individuals was performed and with which assessment tool(s); what items should be included in the assessment; whether they knew about the SCIM, its latest version, the Chinese translation, and if so from what source; the possible reasons why SCIM was not implemented in clinical practice; and whether training before using the SCIM was needed, and the training method preferred.

RESULTS

Among these physicians, 84.8% performed functional outcome measurement for individuals with SCI, but only 29.6% of attendees were aware of the SCIM and 20.8% had used it. Lack of training was the major reason why SCIM was not used in clinical practice. Furthermore, 74.4% of the physicians felt they needed formal training before using the SCIM.

CONCLUSION

The use of SCIM is limited in clinical practice in China, which is mainly attributed to lack of knowledge and training. Formal training on the use of the SCIM is essential for its dissemination and will improve functional SCI outcome measurement in China.

Construct validity, test-retest reliability, and the ability to detect change of the Canadian Occupational Performance Measure in a spinal cord injury population

Study design

Cross-sectional study.

Objectives

To examine the construct validity and the ability to detect change, of the Italian version of the Canadian Occupational Performance Measure (COPM) in a spinal cord injury (SCI) population.

Settings

Rehabilitation service of the Paraplegic Center of Ostia, Italy.

Methods

Thirty-nine spinal cord injury participants were recruited. The clinimetric properties of the measure were assessed following international guidelines. Cronbach's alpha and the intraclass correlation coefficient were assessed for internal consistency and test-retest reliability, respectively. Construct validity was evaluated, by calculating correlation between COPM and the Spinal Cord Independence Measure (SCIM) through Pearson's correlation coefficient and Spearman's Rho. The ability to detect change was evaluated on the overall sample.

Results

The COPM was shown to be reliable in a spinal cord injury sample with positive and statistically significant results for Cronbach's alpha (0.89) and ICC (0.99 for the performance subtest and 0.98 for the satisfaction subtest). Correlation coefficients did not show a correlation between the COPM total score and the SCIM. The COPM scores improved significantly during in-patient rehabilitation, moreover the mean change between the start of treatment and the end of the therapy as evaluated with the Wilcoxon signed-rank test was -4.25 points for the performance score and -2.96 points for the satisfaction score.

Conclusions

This study showed that the COPM is a reliable tool for assessing SCI clients' perceived performance of daily activities and their satisfaction with their performance.

Adaptation and validation of the Caregiver Burden Inventory in Spinal Cord Injuries (CBI-SCI)

DESIGN

Validation cross-sectional study.

OBJECTIVES

Even though caregiver burden (CB) represents a well-recognised concern among caregivers of people with a spinal cord injury (SCI), there are no specific questionnaires designed for its evaluation. This study aimed to assess the psychometric properties of the Caregiver Burden Inventory in Spinal Cord Injury (CBI-SCI), which was modified from its original version, and specifically its construct and reliability.

SETTING

Multicentre study in four urban spinal units across Italy. The CBI-SCI was administered to family caregivers in outpatient clinics.

METHODS

CBI-SCI was administered in a toolset composed of a sociodemographic questionnaire, the Family Strain Questionnaire-Short Form (FSQ-SF), the Short Form-36 (SF-36), and the Modified Barthel Index (MBI). The CBI-SCI construct validity was assessed through an exploratory factor analysis. The internal consistency of the questionnaire was examined using Cronbach's alpha (α) coefficient for the total scale and its subscales. Concurrent validity was evaluated performing Pearson's correlation coefficient with all instruments included in the toolset.

RESULTS

The CBI-SCI was administered to 176 participants from February 2016 to September 2017. Factor analysis highlighted the five-factored structure of the questionnaire. The total scale Cronbach's α was 0.91 (p < 0.001). All the five subscales of CBI-SCI showed an acceptable internal consistency, ranging from 0.76 to 0.91 (p < 0.001). Pearson's correlation coefficients of the CBI-SCI with all the administered instruments were statistically significant (p < 0.001), showing congruent relations.

CONCLUSION

The CBI-SCI, due to its validity and reliability, may represent a valuable instrument to evaluate the CB longitudinally in SCI.

Despite limitations in content range, the SCIM-III is reproducible and a valid indicator of physical function in youths with spinal cord injury and dysfunction

STUDY DESIGN

Multi-center, repeated measures OBJECTIVES: Evaluate psychometric properties of the SCIM-III in children.

SETTING

Seven facilities in North America METHODS: One-hundred and twenty-seven youths, mean age of 10.8 years and chronic spinal cord injury/dysfunction completed two administrations of the Spinal Cord Independence Measure-III (SCIM-III). Mean, standard deviation, range values were calculated for SCIM-III total and subscales for the entire sample, four age groups and injury characteristics. Test-retest reliability, concurrent validity, and floor and ceiling effects were examined.

RESULTS

Total SCIM-III and self-care (SC) subscale scores for the youngest age group were lower than those for the three older age groups. There were statistically significant differences in SC subscale scores between neurological level (NL) C5-T1 and T2 -T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5 and in in-room, and indoor/outdoor mobility subscale scores between C1-C4 and T2-T12; C1-C4 and L1-S4/5; C5-T1 and T2-T12; C5-T1 and L1-S4/5; and T2-T12 and L1-S4/5. All scores between motor complete and motor incomplete differed. Test-retest reliability was good (ICC values = > 0.84) and there was moderate to strong correlation between SCIM-III and the FIM® Instrument (r = 0.77-0.92). Ceiling effects were present in the SC subscale for the oldest age group (24%) and for NL L1-S4/5 (35.5%) and in in-room mobility subscale for 6-12 (45.7%), 13-15 (30.43%) and 16-17 (60%) ages, paraplegia (42.4%), tetraplegia (37.1%), incomplete injuries (50%), and T2-T12 (38%) and L1-S4/5 (100%) NL.

CONCLUSION

Despite limitations in content range, the SCIM-III is reproducible, and a valid indicator of physical functioning in youth with SCI/D 6 years of age and older.

Computer-Assessed Preference-Based Quality of Life in Patients with Spinal Cord Injury

Objectives

Our aims were to (1) measure quality of life (QoL) in spinal cord injury (SCI) patients using different methods and analyze differences; (2) enable targeted treatments by identifying variables that affect QoL; and (3) provide decision-makers with useful data for cost-utility analyses in SCI population.

Methods

Seventy-one participants were enrolled. The computer-based tool UceWeb was used to elicit QoL in terms of utility coefficients, through the standard gamble, time trade-off, and rating scale methods. The SF36 questionnaire was also administered. Statistical analyses were performed to find predictors of QoL among collected variables.

Results

Median values for rating scale, time trade-off, and standard gamble were 0.60, 0.82, and 0.85, respectively. All scales were significantly correlated. Rating scale and SF36 provided similar values, significantly lower than the other methods. Impairment level, male gender, older age, living alone, and higher education were correlated with lower QoL but accounted for only 20% of the variation in utility coefficients.

Conclusions

Demographic and clinical variables are useful to predict QoL but do not completely capture utility coefficients variability. Therefore, direct preference-based utility elicitation should be strengthened. Finally, this is the first study providing data that can be used as a reference for cost-utility analyses in the Italian SCI population.

SCIM III (Spinal Cord Independence Measure version III): reliability of assessment by interview and comparison with assessment by observation

STUDY DESIGN

Psychometric study.

OBJECTIVES

The objective of this study was to examine the reliability of the Spinal Cord Independence Measure III (SCIM III) by interview and compare the findings with those of assessment by observation.

SETTING

This study was conducted at Loewenstein Rehabilitation Hospital, Israel.

METHODS

Thirty-five spinal cord lesion (SCL) patients who underwent rehabilitation at Loewenstein Rehabilitation Hospital in Israel were assessed during the last week before discharge with SCIM III by observation and by interview. Nineteen of the patients were also assessed by interview by a third rater to examine inter-rater reliability. Total agreement, kappa, Bland-Altman plots and intraclass correlation (ICC) were used for comparison between interviewers and between interviews and observations.

RESULTS

Total agreement between the interviewers' scores and between interviews and observations was low to moderate (kappa coefficient 0.11-0.80). Bland-Altman analysis revealed good agreement, with low mean difference for almost all SCIM III subscales and total scores, between pairs of interviewers (bias -4.15, limits of agreement -22.51 to 14.19, for total score) and between interviews and observations (bias 1.62, limits of agreement -20.55 to 23.81, for total score). ICC coefficients for the SCIM III subscales and total scores were high (0.637-0.916).

CONCLUSION

The findings of this study support the reliability and validity of SCIM III by interview, which appears to be useful for research of SCL patient groups. Individual scoring of SCIM III by interview, however, varied prominently between raters. Therefore, SCIM III by interview should be used with caution for clinical purposes, probably by raters whose scoring deviation, in relation to observation scores, is known.
