Twenty-Five-Year Cross-sequential Analysis of Self-reported Problems: Findings From 5 Cohorts From the Spinal Cord Injury Longitudinal Aging Study

OBJECTIVE

To evaluate how self-reported problems change over time among people with spinal cord injury (SCI).

DESIGN

Cross-sequential analysis.

SETTING

Medical university in the Southeastern United States.

PARTICIPANTS

Participants included 1997 individuals with traumatic SCI of at least 1-year duration who were identified from participation in the SCI Longitudinal Aging Study from 1993-2018.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The outcomes analyzed were 6 problem factors defined as health, social isolation, emotional distress, environmental barriers, money, and lack of opportunities. A series of cross-sequential models, using PROC MIXED procedure, were developed to evaluate the initial and change of the 6 problem factors over the 6 times of measurements in 25 years.

RESULTS

Years post injury was negatively associated with initial status of problems of social isolation, emotional distress, environmental barriers, and lack of opportunities because participants with more years post injury at baseline reported lower scores on each factor. Longitudinally, with increased years post injury, higher scores were observed on the health problem factor. However, problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities decreased over time with increasing years post injury.

CONCLUSIONS

Participants had more health problems with increasing years after SCI, but fewer problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities.

Impact of Marital Status on 20-Year Subjective Well-being Trajectories

BACKGROUND

It is well-known that marital status has a significant impact on subjective well-being (SWB). However, research examining the long-term influence of marital status on SWB after spinal cord injury (SCI) is limited.

OBJECTIVE

To identify the relationship between marital status and SWB trajectories over time, using 20 years of longitudinal data.

METHODS

We conducted a cohort study, including 1,032 participants surveyed 5 times in 1993, 1998, 2003, 2008, and 2013. Participants were identified from outpatient records of 2 Midwestern hospitals and 1 Southeastern specialty hospital. The Life Situation Questionnaire-Revised (LSQ-R) was used to measure multiple aspects of SWB. A multilevel model was applied to analyze the 5 repeated measurements.

RESULTS

The married or cohabitating participants enjoyed the best SWB at baseline, but their home satisfaction and global satisfaction declined over time and their social isolation increased slightly. For divorced, separated, or widowed people, the negative effects of marital loss attenuated over time. For single individuals, SWB, except for environmental barriers, did not change positively over time if they remained single.

CONCLUSIONS

Using longitudinal data with 5 repeated measurements, our study showed a complicated relationship between marital and relationship status with SWB and how these relationships change over time for people with chronic SCI.

Household income and subjective well-being after spinal cord injury: a longitudinal study

BACKGROUND

Studies regarding subjective well-being (SWB) after spinal cord injury (SCI) are increasing in recent years, but little has been contributed to the relationship between income and SWB.

OBJECTIVE

By using longitudinal data, we want to identify (1) the overall trend in SWB over a 10-year period; (2) the association between household income and SWB at baseline; (3) the variation of the trajectory of SWB over 10 years among different household income groups; and (4) the variation of change rates of SWB over 10 years among different household income groups.

METHODS

We conducted a cohort study, including 434 participants who completed 3 measurements in 1998, 2003, and 2008. They were identified from outpatient records of 2 midwestern hospitals and a southeastern specialty hospital.

RESULTS

People with lower household income experienced more life problems and less life satisfaction at the baseline measurement. During the 10-year period, their health problems and environmental barriers significantly increased compared to persons with higher income. Increasing vocational satisfaction was the only favorable change for the lower income group.

CONCLUSIONS

There were consistent disparities in SWB related to income, and these typically persisted over time. Therefore, with the exception of vocational satisfaction, few changes may be anticipated in SWB that would narrow the gap between high and low income.

Effects of concurrent respiratory resistance training on health-related quality of life in wheelchair rugby athletes: a pilot study

PURPOSE

To compare the effects of 9 weeks of training with a concurrent flow resistance (CFR) device versus a concurrent pressure threshold resistance (CPTR) device on health-related quality of life (HRQoL) in wheelchair rugby (WR) athletes.

METHOD

Twenty-four male WR athletes (22 with tetraplegia, 1 with a spastic cerebral palsy, and 1 with congenital upper and lower limb deformities) were matched by lesion level, completeness of injury, and rugby classification prior to being randomly assigned to 1 of 3 groups: (1) CPTR (n=8), (2) CFR (n=8), or (3) controls (CON, n=8). Pre/post testing included assessment of HRQoL as measured by the Short-Form Health Survey Version 2.0 (SF-36v2). Manufacturer protocol guidelines for the CFR and CPTR groups were followed for breathing exercises.

RESULTS

Sixteen participants completed the study (CPTR=4, CFR=5, CON=7). The Mann-Whitney U rank order revealed significantly greater reductions in bodily pain (P = .038) and improvements in vitality (P = .028) for CFR versus CON.

CONCLUSION

Results from this study suggest that training with a CFR device improves some aspects of HRQoL (eg, vitality and bodily pain) in WR athletes. Further research with a larger sample size is needed to examine the impact of these devices on improving HRQoL for wheelchair athletes.

Association of spasticity and life satisfaction after spinal cord injury

Objective

To identify the relationship between spasticity and life satisfaction as measured by 3 multi-item factor scales and a rating of overall quality of life among participants with spinal cord injury (SCI).

Study Design

Cross-sectional survey; secondary analysis of existing data by linear regression analysis between spasticity and quality of life.

Setting

Large specialty hospital in the Southeastern United States.

Methods

Participants included 1,549 adults with traumatic spinal cord injuries, at least 18 years of age and a minimum of 1 year post-injury at survey. Outcome measures included: (1) Home Life Satisfaction, (2) Global Satisfaction, (3) Vocational Satisfaction, (4) Overall Quality of Life and (5) three subscales from the Patient Reported Impact of Spasticity Measure.

Results

Three aspects of spasticity (Daily Activities, Positive Impact, and spasticity at its worst) all were negatively correlated with Home Life Satisfaction, Global Satisfaction, and Overall Quality of Life. Only the Daily Activities scale and the spasticity at its worst rating had a significant negative correlation with Vocational Satisfaction.

Conclusion

Spasticity is negatively associated with quality of life after SCI. These negative outcomes need to be considered in an individual’s rehabilitation and treatment methods.
