A longitudinal study of depression in survivors of spinal cord injury

Pain interference and depressive symptom severity across 10 years in individuals with long-term spinal cord injury

OBJECTIVE

To examine change in pain interference and depression over a 10-year time period in individuals with long-term traumatic spinal cord injury (SCI) and to identify the extent to which changes in pain interference over time predicts change in depressive symptoms.

DESIGN

Longitudinal analyses of self-report assessment data.

SETTING

Specialty and university hospitals in the Southeastern and Midwestern United States.

PARTICIPANTS

Adults with a history of traumatic SCI (n = 504) who responded to the three most recent data collection periods of the SCI Longitudinal Aging Study (2008 [Time 1], 2013 [Time 2], and 2018 [Time 3]). The participants averaged 59 years of age and 32 years since injury onset at Time 3.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Patient Health Questionnaire (PHQ-9) assessed depressive symptom severity. The 7-item Pain Interference scale from the Brief Pain Inventory assessed pain interference.

RESULTS

Over the three study timepoints, the sample averaged moderate levels of pain interference and mild depressive symptom severity. Unconditional linear growth models, reflecting changes in central tendency, indicated that pain interference significantly decreased and depressive symptom severity significantly increased over time. Multiple independent variables random coefficient modeling based on correlations suggested that change in pain interference was positively associated with change in depressive symptom severity over the 10-year study follow-up.

CONCLUSION

Average depressive symptom severity worsened over time. Change in pain interference was positively associated with change in depressive symptom severity. These results point to the complexity of aging related changes in depressive symptoms and pain interference. They further support the need for continued assessment of mood and pain experiences, particularly among individuals reaching aging milestones with SCI.

Massive body-brain disconnection consequent to spinal cord injuries drives profound changes in higher-order cognitive and emotional functions: A PRISMA scoping review

Spinal cord injury (SCI) leads to a massive disconnection between the brain and the body parts below the lesion level representing a unique opportunity to explore how the body influences a person's mental life. We performed a systematic scoping review of 59 studies on higher-order cognitive and emotional changes after SCI. The results suggest that fluid abilities (e.g. attention, executive functions) and emotional regulation (e.g. emotional reactivity and discrimination) are impaired in people with SCI, with progressive deterioration over time. Although not systematically explored, the factors that are directly (e.g. the severity and level of the lesion) and indirectly associated (e.g. blood pressure, sleeping disorders, medication) with the damage may play a role in these deficits. The inconsistency which was found in the results may derive from the various methods used and the heterogeneity of samples (i.e. the lesion completeness, the time interval since lesion onset). Future studies which are specifically controlled for methods, clinical and socio-cultural dimensions are needed to better understand the role of the body in cognition.

Relationships between cardiovascular disease risk, neuropathic pain, mental health, and autonomic function in chronic spinal cord injury

STUDY DESIGN

Multicentre, cross-sectional study.

OBJECTIVES

To determine if clinical measures of poor mental health (MH-) and neuropathic pain (NP) are related to increased CVD risk in individuals with chronic spinal cord injury (SCI), and further elucidate the relationships between CVD risk, autonomic function, NP, and MH-.

SETTING

Eight SCI rehabilitation centres in the Netherlands.

METHODS

Individuals (n = 257) with a traumatic, chronic (≥10 yrs) SCI, with age at injury between 18-35 years, completed a self-report questionnaire and a one-day visit to a rehabilitation centre for testing. CVD risk was calculated using Framingham risk score. NP was inferred using The Douleur Neuropathique 4 clinical examination, and MH- was assessed using the five-item Mental Health Inventory questionnaire. Cardiovascular autonomic function was determined from peak heart rate during maximal exercise (HRpeak).

RESULTS

There was a high prevalence of both NP (39%) and MH- (45%) following SCI. MH- was significantly correlated with an adverse CVD risk profile (r = 0.174; p = 0.01), increased the odds of adverse 30-year CVD risk by 2.2 (CI 0.92-2.81, p = 0.02), and is an important variable in determining CVD risk (importance=0.74, p = 0.05). Females (p = 0.05) and those with a higher HRpeak (p = 0.046) tended to be more likely to have NP.

CONCLUSIONS

Clinical measures of MH-, but not NP, are important factors for increased CVD risk following SCI. NP tended to be more prevalent in those with more preserved cardiovascular autonomic function. The interrelationships between secondary consequences of SCI are complex and need further exploration.

Predictors of depression among the elderly persons with disabilities in Indonesia

BACKGROUND

Depression is a major mental problem in the elderly, particularly those with disability. This study's aim was to identify variables that predict depression in the elderly with disabilities.

MATERIALS AND METHODS

This cross-sectional study was conducted in Gunungkidul Regency and Yogyakarta City from April to June 2021. The study participants were community-dwelling elderly aged 60 years and above with disabilities, who could communicate verbally without any apparent cognitive impairment. Data was collected by interviewing participants using structured questionnaire on following sections: Demographic characteristics, Mini-Mental State Examination (MMSE), Washington Group Short Set (WG-SS), Barthel Index of activities of daily living (ADL), Lawton Instrumental ADL (IADL) Scale, and Geriatric Depression Scale-30 (GDS-30). Multivariate linear regression analysis applied to identify variables significantly correlated with depression. Multinomial logistic regression analysis performed to obtain the odds ratio (OR).

RESULTS

Study included 115 elderly persons with disabilities. Most of them had mobility impairment. Higher independence in ADL and being married were related with lower risk of depression, whereas increased age at disability increased the risk of depression (P = 0.001). The elderly who had greater independence with daily activities were less likely to have depression (OR = 0.639 for mild depression and OR = 0.589 for severe depression). Those who were not married were more likely to have mild depression (OR = 3.203) and severe depression (OR = 29.119). compared to the married elderly. Age at acquiring disability was associated with higher risk for mild depression (OR = 1.025) and severe depression (OR = 1.053). Higher independence in ADL and being married were related with lower risk of depression, whereas increased age at disability increased the risk of depression (P = 0.001).

CONCLUSION

Independence in the ADL, being married, and being disabled as a young adult are negative predictors of depression in the elderly with disability.

Suicidal ideation, post-traumatic stress disorder, and depression in traumatic spinal cord injury: What resilience tells us

OBJECTIVE

Identification of unmet psychiatric needs, protective and risk factors for suicide are crucial for people with traumatic spinal cord injury (SCI). In this study, we aimed to explore depression, post-traumatic stress disorder (PTSD) status (non-PTSD, partial-PTSD, full-PTSD), resilience, suicidal ideation (SI) and to examine predictors and clinical correlates of current SI in traumatic SCI.

METHOD

Sixty-three individuals with traumatic SCI who were at least 3 months post-injury were included in the study. The participants were evaluated in terms of PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5), depression, SI, and resilience using the PCL-5, the Patient Health Questionnaire-9, the Brief Resilience Scale, and sociodemographic measures.

RESULTS

33% of our sample (n = 21) had SI over the past two weeks. 71.4% of the patients with SI (n = 15) had depression. A total of 52.4% of the patients with SI (n = 11) were diagnosed with full PTSD. Resilience was found to be significantly lower in individuals with depression and individuals with SI. While depression predicted SI in traumatic SCI, resilience stands as a protective factor against SI.

CONCLUSION

SI is quite common in individuals with traumatic SCI and is accompanied by substantial psychiatric comorbidities such as depression and PTSD. Along with depression and PTSD, resilience - which has protective and predictive values and is inversely associated with SI - constitutes a significant psychotherapeutic intervention and screening area.

Psychological distress 12 years following injury in New Zealand: findings from the Prospective Outcomes of Injury Study-10 years on (POIS-10)

BACKGROUND

Injuries can have detrimental impacts on mental health, even after physical recovery. In our Prospective Outcomes of Injury Study (POIS), 25% of participants experienced psychological distress (assessed using the Kessler 6) three months after a sentinel injury event (SIE), declining to 16% at 24 months post-SIE. Internationally, studies of hospitalised patients found distress persisted beyond 24 months post-injury and remained higher than the general population. However, most studies only assessed distress at one timepoint, relied on long-term recall, or were limited to small samples or specific injury types. Therefore, we aim to describe the prevalence of psychological distress 12 years post-SIE and to investigate pre-injury, injury-related and early post-injury characteristics associated with long-term distress.

METHODS

POIS is a longitudinal cohort study of 2856 New Zealanders injured between 2007 and 2009, who were on the national injury insurer, Accident Compensation Corporation entitlement claims' register. Of these, 2068 POIS participants completed an interview at 24 months and agreed to further contact. They were invited to a follow-up interview 12 years post-SIE which included the Kessler-6 (K6), the psychological distress outcome of interest. Data about a range of pre-injury, injury-related and early (3 months) post-injury characteristics were collected via earlier interviews or administrative data sources (e.g. hospital discharge data).

RESULTS

Twelve years post-SIE, 1543 (75%) people were re-interviewed and 1526 completed the K6; n = 177 (12%) reported psychological distress. Multivariable modified Poisson regression models found pre-injury characteristics were associated with an increased risk of clinically relevant distress at 12 years, i.e. having inadequate income, identifying as Māori, Pacific or Asian and having one mental health condition. Early post-injury psychological distress and dissatisfaction with social relationships also increased risk. However, being older was associated with a reduced risk of distress.

CONCLUSION

Clinically relevant distress persists long-term post-injury among adults with varying injury severity, types and causes, and at higher prevalence than in the general population. Early identification of injured people at risk of long-term psychological distress provides opportunities for timely interventions to reduce psychological distress.

Autonomic variability, depression and the disability paradox in spinal cord injury

STUDY DESIGN

Longitudinal.

OBJECTIVE

With an increased risk of depression in spinal cord injury, the study longitudinally examines depression to understand how post-injury autonomic regulation and coping might be related to somatic and cognitive manifestations of depression after 3 years.

SETTING

Indian Spinal Injuries Center.

METHODS

Twenty-eight spinal cord injury participants completed the follow-up assessment of the Patient Health Questionnaire 3 years post-injury. The participants were grouped based on post-injury autonomic regulation (high and low HRV) and the somatic and cognitive manifestation of depression reflected in a depression ratio. Wilcoxson signed-rank test tested the post-injury (T1) and 3 year follow-up (T2) depression scores.

RESULTS

Depression score reduced after 3 years of injury (p ≤ 0.05). Only the high HRV group showed a higher depression ratio (somatic/ cognitive) atfollow-up (T2) (p ≤ 0.05). No difference was observed in post-injury coping between high and low HRV groups.

CONCLUSION

The reduced depression score at follow-up (T2) aligns with the 'disability paradox' and mightindicate cognitive adaptation, specifically for those who showed autonomic adaptability in the form of post-injury high autonomic variability.

Clinical and demographic predictors of symptoms of depression and anxiety in patients with spinal cord injury

Spinal Cord Injury (SCI) is a condition whose consequences can impact the physical, emotional, and social aspects of patient's life, including Depression and Anxiety disorders.

STUDY DESIGN

Using a cross-sectional design, sociodemographic and clinical data were extracted from 556 SCI patients at the time of initial assessment, prior to intensive rehabilitation treatment at the local rehabilitation institute.

OBJECTIVES

Identify the predictive and multivariate relationship between different sociodemographic and clinical variables of Depression and Anxiety symptoms in SCI patients.

SETTING

Lucy Montoro Rehabilitation Institute (LMRI), University of Sao Paulo, Sao Paulo, Brazil.

METHODS

We performed independent univariate and multivariate regression models using the Hospital Anxiety and Depression Scale (HADS) as dependent variable.

RESULTS

Symptoms of depression and anxiety present in SCI patients negatively correlate with the level of independence for locomotion, personal hygiene, bowel control, social interaction measured by the Functional Independence Scale (FIM), type of medication in use and the Language subtest of the MoCA Scale. Unlike previous studies, we did not find a relationship with the use of alcohol and illicit drugs, injury levels, etiological diagnosis or duration of injury. For the anxiety models, the main predictor was Depression symptoms, with SCI-related aspects not being significant. It was found that characteristics of the FIM Scale and cognitive aspects of the MoCA Scale were the main predictors of symptoms of Depression. Characteristics of the injury and motor deficit were not statistically significant.

CONCLUSIONS

These findings can potentially be used to guide clinical practices to identify patients at higher risk of experiencing symptoms of Depression and Anxiety.

Non-opioid pharmacologic treatment of chronic spinal cord injury-related pain

Purpose: Spinal cord injury-related pain is often a severe debilitating condition that adversely affects the patient's physical health, psychological wellbeing and quality of life. Opioid medications have historically been prescribed to this population with great frequency. As opioid abuse disorder becomes an ever-worsening public health issue, more attention must be placed upon non-opioid options. This paper reviews non-opioid medications to be considered when treating spinal cord injury-related pain. The pertinent literature is reviewed, and the advantages and pitfalls of various medication options are discussed in the complicated context of the individual with a spinal cord injury.Methods: Peer-reviewed journal articles and medication package insert data are reviewed.Results:. The non-opioid medications with the greatest evidence for efficacy in the treatment of chronic spinal cord injury-related pain are drawn from the antiepileptic drug and antidepressant categories though the specific selection must be nuanced to the particular individual patient. More research is required to understand the role of calcitonin, lithium, and marijuana in treating spinal cord injury-related pain.Conclusions: The complex clinical situation of each individual patient must be weighed against the risks and benefits of each medication, as reviewed in this paper, to determine the ideal treatment strategy for chronic spinal cord injury-related pain.

The Relationship between Cognitive Performance and Quality of Life in Elite Athletes after Spinal Cord Injury

BACKGROUND

The present investigation was designed to determine cognitive performance and quality of life (QoL) in a group of elite athletes who sustained spinal cord injury (SCI).

METHODS

nine participants suffering a SCI participated in the study. Different cognitive functions were evaluated through the following tests: COWAT, Digit Span, Stroop color-word and QoL through the WHOQoL-BREF scale.

RESULTS

Generally, participants positively assessed their overall quality of life and health status. Although the tests conducted indicate reduced cognitive function among the athletes, it did not affect the reduction in QoL. Single correlations between the results of cognitive tests and QoL could be treated as coincidental.

CONCLUSIONS

Despite the observed decline in selected cognitive functions, the participants positively assessed their quality of life and physical health.Reduced cognitive functioning could be influenced by the impact of sleep-disordered breathing, pain, depressive disorders and medication. This indicates the need for an individualized approach to define the patient's deficits, needs and best care. Further studies with a larger group of participants are needed.

Greener on the other side? an analysis of the association between residential greenspace and psychological well-being among people living with spinal cord injury in the United States

STUDY DESIGN

Secondary analysis of cross-sectional data from a multisite survey study.

OBJECTIVES

To describe associations between residential greenspace and psychological well-being among adults living with chronic spinal cord injury (SCI).

SETTING

Community.

METHODS

Participants were from the Spinal Cord Injury-Quality of Life (SCI-QOL) Calibration Study (N = 313). Geographic Information Systems (GIS) analysis was used to define five- and half-mile buffer areas around participants' residential addresses to represent community and neighborhood environments, respectively, and to create measures of natural and developed open greenspace. Associations of greenspace measures with two SCI-QOL psychological well-being domains (positive affect and depressive symptoms) were modeled using ordinary least squares (OLS) regression, adjusted for demographic, injury-related, and community socioeconomic characteristics.

RESULTS

People living in a community with a moderate amount of natural greenspace reported less positive affect and more depressive symptoms compared to people living in a community with low natural greenspace. At the neighborhood level, a moderate amount of developed open space was associated with less positive affect and more depressive symptoms than a low amount of developed open space.

CONCLUSIONS

Contrary to expectations, residential greenspace had a negative relationship with psychological well-being in this sample of adults with SCI. Understanding how and why natural spaces are associated with quality of life for people with mobility disabilities can influence public policy and urban planning designs to ensure that residential greenspaces are accessible and beneficial to all.

Relationship of patient characteristics and inpatient rehabilitation services to 5-year outcomes following spinal cord injury: A follow up of the SCIRehab project

OBJECTIVE

To examine associations of patient characteristics and treatment quantity delivered during inpatient spinal cord injury (SCI) rehabilitation with outcomes at 5 years post-injury and compare them to the associations found at 1 year post-injury.

DESIGN

Observational study using Practice-Based Evidence research methodology in which clinicians documented treatment details. Regression modeling was used to predict outcomes.

SETTING

Five inpatient SCI rehabilitation centers in the US.

PARTICIPANTS

Participants were 792 SCIRehab participants who were >12 years of age, gave informed consent, and completed both a 1-year and 5-year post-injury interview.

OUTCOME MEASURES

Outcome data were derived from Spinal Cord Injury Model Systems (SCIMS) follow-up interviews at 5 years post-injury and, similar to the 1-year SCIMS outcomes, included measures of physical independence, societal participation, life satisfaction, and depressive symptoms, as well as place of residence, school/work attendance, rehospitalization, and presence of pressure ulcers.

RESULTS

Consistent with 1-year findings, patient characteristics continue to be strong predictors of outcomes 5-years post-injury, although several variables add to the prediction of some of the outcomes. More time in physical therapy and therapeutic recreation were positive predictors of 1-year outcomes, which held less true at 5 years. Greater time spent with psychology and social work/case management predicted greater depressive symptomatology 5-years post-injury. Greater clinician experience was a predictor at both 1- and 5 -years, although the related positive outcomes varied across years.

CONCLUSION

Various outcomes 5-years post-injury were primarily explained by pre-and post-injury characteristics, with little additional variance offered by the quantity of treatment received during inpatient rehabilitation.

Appraisals of disability and psychological adjustment in veterans with spinal cord injuries

Context/Objective: Following a spinal cord injury or disability (SCI/D), cognitive appraisals are a marker of psychological adjustment. The present study evaluated the clinical utility and discriminant validity of the Appraisals of DisAbility Primary and Secondary Scale - Short Form (ADAPSS-sf). The ADAPSS-sf was evaluated on 1. identification of individuals experiencing poor psychological adjustment and 2. prediction of life satisfaction beyond measures of emotional distress.Design: A retrospective study was completed using ROC analyses and odds ratios to identify the clinical utility of the ADAPSS-sf. In addition, blocked hierarchical regression explored the ADAPSS-sf predictive characteristics for satisfaction with life beyond measures of emotional distress.Setting: Veteran's Health Administration SCI Center.Participants: Ninety outpatient veterans with SCI/Ds.Outcome Measures: Measures of psychological adjustment post-SCI/D included the PHQ-9, GAD-7, PC-PTSD, and the Diener Satisfaction with Life Scale (SWLS). The ADAPSS-sf was used as a measure of cognitive appraisals.Results: Results indicated the ADAPSS-sf is effective in identification of poor psychological adjustment, P < .001. Diagnostic odds ratios and ADAPSS-sf cut scores were selected to prioritize sensitivity (7.17, ≤ 11), specificity (68.25, ≥ 22), or a balance of the two (16.32, ≤ 19). Hierarchical regression indicated the ADAPSS-sf accounted for unique variance in life satisfaction beyond measures of emotional distress, (ΔR² = .20, β = -.66, t(89) = 6.54, P < .001).Conclusion: Results indicated SCI/D specific appraisals are predictive of concurrent poor psychological adjustment and provide insight into satisfaction with life beyond measures of emotional distress.

Shorter telomeres among individuals with physical disability: The moderating role of perceived stress

OBJECTIVES

Evidence suggests that individuals with physical disability may suffer from psychological distress and accelerated cellular aging, manifested by shortened telomere length (TL), compared with healthy individuals. Studies indicate that high levels of perceived stress and depression may increase the physiological susceptibility and thus, may contribute to a short TL. However, the moderating role of perceived stress and depression within the relationship between physical disability and TL remains unknown.

METHODS

The participants consisted of 119 male subjects (mean age 54.36 years, range 35-70). Of them, 30 were able-bodied and 86 had a physical disability: 34 were due to Poliomyelitis (polio) and 55 were due to spinal cord injury (SCI). Blood samples for TL analysis were collected; the participants completed questionnaires and underwent disability evaluation.

RESULTS

Participants with disability had a shorter TL as well as elevated levels of perceived stress and depression compared with able-bodied controls. Both the perceived stress and depression were correlated with a shorter TL. Nonetheless, perceived stress, rather than depression, moderated the relationship between disability and TL; among participants with higher perceived stress levels, in particular, individuals with physical disability had a shorter TL than the able-bodied controls.

DISCUSSION

The present findings suggest that individuals with physical disability and who exhibit high levels of perceived stress may be particularly vulnerable for accelerated cellular aging, suggesting that perceived stress can be used as a valuable target for intervention.

Quality of Life after Surviving a Spinal Cord Injury: An Observational Study in South India

Background

Spinal cord injury (SCI) and its negative impact on the quality of life (QOL) is a significant public health concern in India. People with SCI suffer from serious health, economic, and social consequences in their lives. Often, care for SCI survivors is left to their immediate family members in India. Appropriate planning is needed for prevention, rehabilitation, health, and psychological care for SCI in the country.

Purpose

This study assessed the overall QOL of SCI survivors and their satisfaction levels with specific domains and their importance of QOL.

Materials and Methods

In this observational study, two instruments, Farrens and Power for QOL and Barthel Index for functional abilities, were administered to a convenience sample of participants drawn from Narayana Medical College, Nellore, in South India.

Results

Statistically, SCI survivors were found moderately and very satisfied with their QOL. Their perception about importance of health, functioning, social, and economic subscale also did not differ statistically.

Purpose in Life of Elite Athletes after Spinal Cord Injury

Background: Searching for the meaning of human existence is man’s fundamental orientation. People are free to find meaning in their lives, and while they are not always free to choose the conditions of life, they are free to choose their attitude toward the conditions in which they find themselves. When people experience an unchangeable situation, the most important thing is the attitude they take toward it. This study aimed to identify the sense of meaning in life among elite athletes after a spinal cord injury (SCI) and to analyze the different aspects contributing to this domain. Methods: The study involved five athletes with at least national-level achievements in sports prior to a SCI. The study consisted of an interview using a communicator and filling out two online questionnaires—a personal questionnaire and the Purpose in Life Scale. Results: Analyzing the quantitative results, four participants achieved results indicating a high sense of meaning in life, while one participant achieved a significantly lower result. Conclusions: What affects one’s purpose in life is not so much the objective physical limitation but how much physicality one perceives to have lost as a result of the injury. Elite athletes stay involved in the sporting environment, which prevents the loss of purpose and maintains a sense of meaning at a high level. Both telling the story of your own illness and listening to the stories of others help the process of self-healing.

Mediating Effects of Pain Interference on the Relationships Between Pain Intensity and Probable Major Depression Among Participants With Spinal Cord Injury

OBJECTIVE

To evaluate whether pain interference mediates the relationship between pain intensity and probable major depression (PMD) among persons with spinal cord injury (SCI), accounting for differences in the frequency of prescription medication use and resilience.

DESIGN

Cross-sectional analysis using self-report assessment.

SETTING

Medical university in the Southeastern United States.

PARTICIPANTS

There were a total of 4670 participants (N=4670), all of whom had traumatic SCI of at least 1-year duration, identified from the Southeastern Regional SCI Model System and 2 state-based surveillance systems.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The Patient Health Questionnaire-9 was used to define PMD. Covariates included demographic and injury characteristics, pain severity, pain interference, and resilience. Separate sets of multistage logistic regression analyses were conducted for 3 levels of prescription pain medication use (daily, occasional/weekly, none).

RESULTS

Pain intensity was related to a greater risk of PMD (odds ratio [OR]_{daily pain medication user}, 1.28; 95% confidence interval [CI], 1.21-1.35; OR_{occasional/weekly pain medication user}, 1.26; 95% CI, 1.16-1.36; OR_{nonpain medication user}, 1.44; 95% CI, 1.33-1.56), but this relationship disappeared after consideration of pain interference (OR_{daily pain medication user}, 0.97; 95% CI, 0.90-1.04; OR_{occasional/weekly pain medication user}, 0.94; 95% CI, 0.84-1.05; OR_{nonpain medication user}, 1.07; 95% CI, 0.95-1.20), which indicates pain interference was a mediator between pain intensity and PMD and there was no direct relationship between pain intensity and PMD. Resilience was protective of PMD in each model but was not a mediator.

CONCLUSIONS

Although pain intensity was associated with PMD, the relationship was mediated by pain interference. Resilience was an important protective factor. Therefore, clinicians should assess pain interference when screening for PMD and direct treatment at reducing pain interference. Building resilience may further reduce the risk of PMD.

Associations between post-traumatic growth and wisdom in people with long-term paraplegia - the role of disability appraisals and participation

PURPOSE

The number of people with long-term spinal cord injury (SCI) is growing but our knowledge about their successful functioning is still limited. The goal of this study was to investigate the correlations between posttraumatic growth (PTG) and wisdom in people with long-term paraplegia, exploring the mediating effect of disability appraisals, and participation/autonomy (P/A).

METHODS

One-hundred and sixty-six persons with paraplegia completed a set of questionnaires, which included: The three-dimensional Wisdom Scale; The Post-traumatic Growth Inventory; Appraisals of Disability Primary and Secondary Scale; Impact on Participation and Autonomy Questionnaire. Mediation was tested using bootstrapping and a multiple mediation model with two mediators.

RESULTS

Positive and significant correlations between PTG, disability appraisals (as determined resilience), P/A, and wisdom were found. PTG is associated with wisdom when disability appraisals and P/A are mediators. Higher PTG was related to higher determined resilience and smaller restrictions in participation, both of which were associated with higher wisdom.

CONCLUSIONS

The relationship between PTG and wisdom is complex and indirect in people with long-term paraplegia. The mediating variables of disability appraisals and P/A explained the variance in PTG, with P/A playing a more significant role. Findings suggest that long-term SCI may correlate with experiencing high levels of PTG and wisdom, and more positive disability appraisals.Implications for rehabilitationPTG is associated with life wisdom in people with long-term SCI, with a significant contribution of disability appraisal and P/A.Therapists can increase these people's awareness about the possibility of experiencing PTG and maintaining positive changes, despite long-term SCI.Therapists can support people with long-term SCI in maintaining or extending the possibilities of participation and autonomous decision-making about their daily activities, which in consequence may be important for increasing their life wisdom.

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.

Changes in health-related quality of life among older adults aging with long-term spinal cord injury

STUDY DESIGN

Cross-sectional and longitudinal.

OBJECTIVES

To (i) describe health-related quality of life (HRQoL) and changes over 6 years in older adults aging with long-term spinal cord injury (SCI) and (ii) investigate how changes in HRQoL are associated with age, gender, and injury characteristics.

SETTING

Community in southern Sweden.

METHODS

From the initial 123 participants (years 2011-2012) in the Swedish Aging with Spinal Cord Injury Study (SASCIS), 77 individuals (32% women, C1-L3, AIS A-D, median age 66 years, median time since injury 31 years, 30% complete injuries) were assessed 6 years later. HRQoL was rated with the Spinal Cord Injury Quality of Life Questionnaire (SCI QL-23). Associations were investigated using multivariable linear regression analyses.

RESULTS

The median rating of global QoL (scale range 0-100) was relatively high at both assessments (67 and 83, respectively). There was a large variability in all HRQoL-domains and no significant changes over 6 years. As compared to an AIS D injury, a tetraplegia AIS A-C injury and tetraplegia and paraplegia AIS A-C injuries were associated with positive change in depressive symptoms and global QoL, respectively.

CONCLUSIONS

Older adults aging with long-term SCI show large variations in all HRQoL-domains and have the potential to maintain a high and stable level of HRQoL over time. Persons with AIS D injuries may need increased attention to mitigate negative changes in depressive symptoms and global QoL. Further studies are needed to identify modifiable factors associated with changes in HRQoL in older adults aging with long-term SCI.

Effects of Scrambler Therapy in Patients with Failed Back Surgery Syndromes and Factors Associated with Depression Affecting Pain before and after the Therapy

Objectives

To report the effects of scrambler therapy in patients diagnosed with failed back surgery syndromes and to analyze the factors affecting pain before and after the therapy.

Methods

This study included 26 patients (12 males and 14 females). The Oswestry Disability Index (ODI) and Brief Pain Inventory (BPI) before and after scrambler therapy, Beck Depression Inventory (BDI) score before therapy, and residual pain after therapy were assessed. The changes in the ODI, BPI, and residual pain before and after the therapy were analyzed using the Wilcoxon signed rank test. Spearman correlation analysis and Fisher's exact test were used to confirm the correlation between BDI and other factors. Multiple regression analysis was used to identify independent factors predicting residual pain, posttherapy ODI, and posttherapy BPI.

Results

The ODI changed from 25.69 ± 7.98 to 21.80 ± 9.41 (p < 0.05), and the BPI changed from 68.96 ± 18.00 to 61.62 ± 20.27 after scrambler therapy (p < 0.05). In addition, residual pain changed from 100 to 76.15 (p < 0.05). The BDI was negatively correlated with the duration of scrambler therapy and positively correlated with the initial OPD and BPI. In multiple regression analysis, residual pain was significantly correlated with the BDI (p < 0.05).

Conclusion

Scrambler therapy can be used to change the total scores of the ODI and BPI after 5 sessions of treatment. Also, residual pain was significantly related to the BDI. Clinical significance of depression severity on pain should be further investigated via prospective studies.

Employment, health outcomes, and life satisfaction after spinal cord injury: comparison of veterans and nonveterans

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To explore differences between veterans and nonveterans with spinal cord injury (SCI) for employment, health, and satisfaction with life outcomes after controlling for demographic and injury characteristics.

SETTING

Hospitals in the Spinal Cord Injury Model System of care.

METHODS

A total of 9754 (85% nonveterans and 15% veterans) adults with traumatic SCI interviewed from 2000 and 2015 and completed follow-up years 1, 5, and 10 were included in this study. Employment status and the Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) measured employment. The SF-36 for self-perceived health status, CHART-SF, and rehospitalization determined health outcomes. Satisfaction with life was measured by the Satisfaction with Life Scale (SWLS). Secondary data analyses using χ2, t-tests, and generalized estimating equations (GEEs) model to determine group differences with control of demographic and injury characteristics.

RESULTS

There were no significant differences for employment and SWL between nonveterans and veterans. There were some differences in health outcomes; whereas, veterans had better physical independence and mobility compared with nonveterans.

CONCLUSION

Interventions for both groups should target adults with a disability from SCI, be customized for varying levels of injury that address differences in healthcare systems, demographic backgrounds, economic resources, disincentives, and motivation.

Associations Between Doing Planned Exercise and Probable Major Depressive Disorder in Individuals Following Spinal Cord Injury

Background: In neurologically healthy individuals, exercise positively impacts depressive symptoms, but there is limited knowledge regarding the association between exercise behaviors and depression after spinal cord injury (SCI). Objective: To examine associations between doing planned exercise and probable major depressive disorder (PMDD) after SCI. Methods: Community-dwelling adults, who were one or more years post traumatic SCI, completed self-report assessments at baseline (Time 1) and an average of 3.29 years later (Time 2). Patient Health Questionnaire-9 was used to assess depressive symptoms. Participants self-reported frequency of doing planned exercise. There were 1,790 participants who responded at both Time 1 and 2. Associations were analyzed using logistic regression. Results: Prevalence of PMDD was 10% at Time 1 and 12% at Time 2. Only 34% of participants at Time 1 and 29% at Time 2 reported doing planned exercise three or more times per week. The majority of participants (47%) reported no change in frequency of doing planned exercise between Times 1 and 2. Significant risk factors for PMDD at Time 2 included low household income (p = .0085), poor to fair self-perceived health (p < .0001), and doing less planned exercise at Time 2 (p = .0005). Meanwhile, number of years post injury (p = .04), doing planned exercise three or more times per week at Time 1 (p = .0042), and doing more planned exercise at Time 2 (p = .0005) were associated with decreased odds of PMDD at Time 2. Conclusion: These results demonstrate that a negative association exists between doing planned exercise and PMDD post SCI. Future longitudinal studies are needed to further explain these findings.

Correlation between thyroid function, testosterone levels, and depressive symptoms in females with spinal cord injury

Study Design

Prospective case series.

Objective

Investigate the association of testosterone and thyroid-stimulating hormone (TSH) levels with depressive symptoms in women after spinal cord injury (SCI).

Setting

Community SCI clinic.

Methods

Twenty-seven participants were enrolled in this study. Total testosterone (Total T) and TSH levels as well as the Center for Epidemiological Studies Depression Scale (CES-D) survey and monthly sexual activity were obtained from only 20 participants. Pearson's correlations were used to assess the relationship between age, time from injury, Total T level, TSH level, and CES-D total score. Follow-up analyses investigating the role of monthly sexual activity was also explored.

Results

Participants' average age and time from injury was 44.4 ± 12.7 years old and 11.7 ± 8.89 years, respectively. Low Total T was observed in four participants and one of those participant's presented with low TSH as well. Nine women were classified as "at risk for clinical depression" on the CES-D (total score >15). Pearson's correlations revealed a significant association between time from injury and TSH (r = .536, p = .015), as well as CES-D total score (r = -.547, p = .013). Total T was associated with CES-D total score (ρ = -.541, p = .02).

Conclusions

This study provides preliminary results on abnormal hormone levels and depressive symptoms in women after SCI. Twenty percent of this sample presented with low Total T, which was associated with increased depressive symptoms after accounting for time from injury. Further research is needed to investigate the impact of SCI on hormone function and mental health in women post SCI.

Mental health in individuals with spinal cord injury: The role of socioeconomic conditions and social relationships

OBJECTIVES

To evaluate socioeconomic inequalities in social relationships, and to assess whether socioeconomic conditions and social relationships are independently related to mental health problems in individuals with a physical disability due to spinal cord injury (SCI).

METHODS

We analyzed cross-sectional data from 511 individuals with SCI aged over 16 years who participated in the community survey of the Swiss SCI Cohort Study (SwiSCI). Indicators for socioeconomic conditions included years of formal education, household income, and financial strain. Social relationships were operationalized by three structural (partner status; social contact frequency; number of supportive relationships) and four functional aspects (satisfaction with: overall social support; family relationships; contacts to friends; partner relationship). General mental health was assessed by the Mental Health Inventory (MHI-5) of SF-36 and depressive symptoms were measured by the Hospital Anxiety and Depression Scale (depression subscale, HADS-D). Established cut-offs for general mental health problems (MHI-5 ≤56) and depressive symptomatology (HADS-D ≥8) were used to dichotomize outcomes. Associations were assessed using logistic regressions.

RESULTS

Lower household income was predominantly associated with poor structural social relationships, whereas financial strain was robustly linked to poor functional social relationships. Financial strain was associated with general mental health problems and depressive symptomatology, even after controlling for social relationships. Education and household income were not linked to mental health. Poor structural and functional social relationships were related to general mental health problems and depressive symptomatology. Notably, trends remained stable after accounting for socioeconomic conditions.

CONCLUSION

This study provides evidence for socioeconomic inequalities in social relationships as well as for independent associations of financial strain and poor social relationships with mental health problems in individuals with SCI. Further research may develop strategies to improve mental health in SCI by strengthening social relationships. Such interventions may be especially beneficial for individuals with low income and financial strain.

Outcomes in socioeconomically disadvantaged patients with spinal cord injury: a systematic review

OBJECTIVEIndividuals with a spinal cord injury (SCI) in socioeconomically disadvantaged settings (e.g., rural or low income) have different outcomes than their counterparts; however, a contemporary literature review identifying and measuring these outcomes has not been published. Here, the authors' aim was to perform a systematic review and identify these parameters in the hope of providing tangible targets for future clinical research efforts.METHODSA systematic review was performed to find English-language articles published from 2007 to 2017 in the PubMed/MEDLINE, EMBASE, and SCOPUS databases. Studies evaluating any outcomes related to patients with an SCI and in a low-resource setting were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a flowchart was created. Of the 403 articles found, 31 underwent complete review and 26 were eligible for study inclusion. According to the current study criteria, any case studies, studies in less developed countries, studies including and not separating other types of neurological disorders, studies not assessing the effects of a low-resource setting on outcomes in patients with SCI, and studies evaluating the causes of SCI in a low-resource setting were excluded.RESULTSIn SCI patients, a lower income was a predictor of death (OR 2.1, 95% CI 1.7-2.6, p = 0.0002). Moreover, secondary outcomes such as pain intensities (OR 3.32, 95% CI 2.21-4.49, p < 0.001), emergency room visits (11% more likely, p = 0.006), and pressure ulcer formation (OR 2.1, 95% CI 1.5-3.0, p < 0.001) were significantly higher in the lower income brackets. Rurality was also a factor and was significantly associated with increased emergency room visits (OR 1.5, 95% CI 1.1-2.1, p = 0.01) and lower outpatient service utilization (incidence rate ratio [IRR] 0.57, 95% CI 0.35-0.93, p < 0.05).CONCLUSIONSThe authors showed that individuals in a low-resource setting who have suffered an SCI have significantly different outcomes than their counterparts. These specific outcomes are promising targets for future research efforts that focus on improving health conditions among this population.

Depressive mood in individuals with spinal cord injury (SCI) living in Greece

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To provide data on depressive symptoms rates in the Greek SCI population and to investigate their association with demographic and clinical variables.

SETTING

Greek territory.

METHODS

One hundred and sixty-four individuals with SCI living in the community for at least 1 year after the completion of the primary inpatient rehabilitation program were included in the study. Our group of participants were enrolled from multiple rehabilitation centers throughout Greece and were evaluated for probable depression according to the Patient Health Questionnaire (PHQ-9). Univariable and multiple linear regression analyses were performed to assess the possible association of risk factors with the occurrence of depression. We had also examined the correlation between PHQ-9 and scales measuring social reintegration (Craig Handicap Assessment and Reporting Technique (CHART)), quality of life (World Health Organization Quality of Life BREF (WHOQOL-BREF)), and independence (Spinal Cord Independence Measure (SCIM)).

RESULTS

It was found that 18.2% of the sample had probable depression. The mean (SD) PHQ-9 score was 5.7  (4.9). The multiple linear regression analysis showed that high pain scores (P = 0.001) and suffering from both nociceptive and neuropathic pain (P = 0.005) were associated with depressive mood, while pressure ulcers had a significant effect (P = 0.049) only in the univariable analysis. Participant's PHQ-9 scores had also a negative correlation with almost all CHART, WHOQOL-BREF, and SCIM subscales' scores.

CONCLUSIONS

This study documents relatively low rates of probable depression among individuals with SCI in Greece. Severe pain and pressure ulcers were the main identified predictors of depressive mood.

The Patient Health Questionnaire depression screener in spinal cord injury

CONTEXT

Although depression is not inevitable following spinal cord injury/dysfunction (SCI/D), it can have a negative impact on rehabilitation. Evidence-based assessment of depression utilizing self-report instruments, such as the Patient Health Questionnaire-9 (PHQ-9), is considered good clinical practice. Although the PHQ-9 has been studied in individuals with SCI/D, little is known about the clinical utility of the Patient Health Questionnaire-2 (PHQ-2). Traditional cutoff scores for the PHQ-2 were examined to explore their operating characteristics as related to PHQ-9 results.

METHODS

Archival data were collected for 116 Veterans with SCI/D who completed the PHQ-2 and PHQ-9 as one component of their routine, comprehensive SCI annual evaluation at a Veterans Affairs Medical Center. Logistic regressions were performed to determine the impact of different cutoff scores for the PHQ-2 on the likelihood that participants would endorse clinically significant levels of depressive symptoms on the PHQ-9 (≥10).

RESULTS

Using a cutoff score of 3 or greater correctly classified 94.8% of the cases, outperforming the other cutoff scores. A cutoff score of 3 or greater had a sensitivity of 83.3% and specificity of 97.8%, and yielded a positive predictive value of 90.9% and a negative predictive value of 95.7%.

CONCLUSION

The PHQ-2 shows promise as a clinically useful screener in the community-residing SCI/D population. Findings regarding the presence of suicidal ideation emphasize the importance of routine screening for depressive symptomatology in the SCI/D population. Future research should investigate the role of the PHQ-2 in clinical decision-making and treatment monitoring.

From acute to chronic back pain: Using linear mixed models to explore changes in pain intensity, disability, and depression

Background/aims

This longitudinal study investigated the pattern of change in pain intensity, disability, and depression in 232 chronic pain patients who were followed up for 2 years since pain onset. Most studies that have investigated changes in these variables over time have used participants who had already been in pain for more than 3 months. Few studies have followed up individuals from the acute phase onward and such studies used traditional statistical methods that cannot identify transition points over time or measure inter-individual variability.

Methods

We followed up individuals with chronic pain from pain onset up to 18 months and we examined their pain intensity, disability and depression trajectories using a modelling approach that allows to account for between and within-individual variability. We compared three patterns of change based on theoretical criterions: a simple linear growth model; a spline model with a 3-month transition point; and a spline model with a 6-month transition point. Time with pain was selected as time metric to characterise the change in these variables in the transition from acute to chronic pain. Sex and age differences were also examined.

Results

The results showed that the pain intensity trajectory was best represented by the spline model with a 3-month transition point, whereas disability and depression were best explained by linear growth models. There were sex differences at intercept level in all the models. There were age differences at baseline for pain intensity. No sex or age differences were found for the slope.

Conclusions

Pain intensity decreased in the first 3 months but underwent no further change. Disability and depression slightly but constantly decreased over time. Although women and older individuals are more likely to report higher pain intensity or pain-related disability in the first three months with pain, no differences by sex or age appear to be associated with the changes in pain intensity, depression and disability through the process of chronification.

Implications

Our findings suggest that pain chronification could be considered a continuous process and contribute to the ongoing discussion on the utility of standard classifications of pain as acute or chronic from a clinical point of view. Clinical and intervention decisions based in these standard classifications should consider the differences in the trajectories of pain related variables over time. In addition, this article illustrates a statistical procedure that can be of utility to pain researchers.

Social activity and relationship changes experienced by people with bowel and bladder dysfunction following spinal cord injury

STUDY DESIGN

Exploratory qualitative.

OBJECTIVES

The aim of this study was to describe the experiences of bowel and bladder dysfunction on social activities and relationships in people with spinal cord injury living in the community.

SETTING

People living with spinal cord injury experiencing bowel and bladder dysfunction.

METHODS

Participants were recruited through the Australian Quadriplegic Association Victoria. Semi-structured in-depth interviews were undertaken with purposively selected participants to ensure representation of age, gender, spinal cord injury level and compensation status. A thematic analysis was performed to interpret patient experiences.

RESULTS

Twenty-two participants took part in the study. Bladder and bowel dysfunction altered relationships because of issues with intimacy, strained partner relationships and role changes for family and friends. A lack of understanding from friends about bladder and bowel dysfunction caused frustration, as this impairment was often responsible for variable attendance at social activities. Issues with the number, location, access and cleanliness of bathrooms in public areas and in private residences negatively affected social engagement. Social activities were moderated by illness, such as urinary tract infections, rigid and unreliable bowel routines, stress and anxiety about incontinence and managing the public environment, and due to continuous changes in plans related to bowel and bladder issues. Social support and adaptation fostered participation in social activities.

CONCLUSION

Tension exists between managing bowel and bladder dysfunction and the desire to participate in social activities. Multiple intersecting factors negatively affected the social relationships and activities of people with spinal cord injury and bowel and bladder dysfunction.

Anxiety and Depression in Patients with Traumatic Spinal Cord Injury: A Nationwide Population-Based Cohort Study

BACKGROUND

Traumatic spinal cord injury (tSCI) may involve new-onset anxiety and depression post-discharge. However, long-term population-based studies have lacked access to follow-up conditions in terms of new-onset anxiety and depression. The objective of this study was to estimate the long-term risk of new-onset anxiety and depression post-discharge.

METHODS

The Longitudinal Health Insurance Database 2000 (LHID2000) from Taiwan's National Health Insurance Research Database was used in this study. Individuals with tSCI were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic codes of 806 and 952 from 1999-2008. The comparison cohort (other health conditions group) was randomly selected from the LHID2000 and was 1:1 matched by age, sex, index year, and comorbidities to reduce the selection bias. All study participants were retrospectively followed for a maximum of 3 years until the end of follow-up, death, or new-onset anxiety (ICD-9-CM: 309.2-309.4) or depression (ICD-9-CM: 296.2, 296.5, 296.82, 300.4, 309.0-309.1, and 311). Persons who were issued a catastrophic illness card for tSCI were categorized as having a severe level of SCI (Injury Severity Score [ISS] ≥16). Poisson regression was used to estimate the incidence rate ratios of anxiety or depression between patients with tSCI and other health conditions. The relative risk of anxiety or depression was estimated using a Cox regression analysis, which was adjusted for potential confounding factors.

RESULTS

Univariate analyses showed that the tSCI patients (n = 3556) had a 1.33 times greater incidence of new-onset anxiety or depression (95% confidence interval [CI]: 1.12-1.57) compared to the other health conditions group (n = 3556). After adjusting for potential risk factors, the tSCI patients had a significant 1.29-fold increased risk of anxiety or depression compared to the group with other health conditions (95% CI: 1.09-1.53). Individuals with tSCI, including patients who were under the age of 35, patients who were males, patients who had a low income, and patients without a Charlson Comorbidity Index score, all had a higher long-term risk of anxiety or depression than the other health conditions group (IRRs: 1.84, 1.63, 1.29, and 1.39, respectively). For all tSCI patients, those with an Injury Severity Score (ISS) ≥16 had an almost 2-fold higher risk of anxiety or depression (adjusted Hazard Ratio: 1.85; 95% CI: 1.17-2.92) compared to those with ISS <16.

CONCLUSIONS

Our findings indicated that tSCI patients have a high risk of anxiety or depression post-discharge, especially among the younger tSCI patients (age <50 years), compared with the other health conditions group. This information could help physicians understand the long-term risk of new-onset anxiety or depression in tSCI patients post-discharge.

Depressive symptomatology after spinal cord injury: A multi-center investigation of multiple racial-ethnic groups

OBJECTIVE

To identify (1) racial-ethnic differences in depressive symptomatology after spinal cord injury (SCI) and (2) the relationship of multiple additional factors to depressive symptoms, including health behaviors, employment, fatigue, and pain interference.

DESIGN

Cross-sectional Setting: Data were collected at 3 specialty hospitals in different regions of the USA (Southeastern, Mountain, Western).

PARTICIPANTS

Participants (N = 1,063) were identified from outpatient records of the 3 hospitals with oversampling of racial-ethnic minority groups.

INTERVENTIONS

N/A Main Outcome Measure(s): The outcome, depressive symptomatology, was measured by the Older Adult Health and Mood Questionnaire (OAHMQ). Participant demographic and injury characteristics were measured as statistical controls, as well as other variables including health behavior factors, depression/stress relief medication usage, fatigue, and pain interference. The multivariate analyses were developed using OLS regression models and logistic regression models.

RESULTS

Employment was protective for depressive symptomatology, whereas fatigue, pain interference, and binge drinking were risk factors for higher OAHMQ scores. Although there were no bivariate racial-ethnic differences in depressive symptoms, fatigue and pain interference had suppression effects on the relationship between race-ethnicity and depressive symptomatology. After controlling for fatigue and pain interference, Hispanic participants had significantly lower OAHMQ scores and lower odds of probable major depression (PMD) than non-Hispanic Whites and Blacks.

CONCLUSIONS

Fatigue and pain interference are associated with both race-ethnicity and depressive symptomatology. Assuming the same level of fatigue and pain interference, Hispanics will have a lower risk of depressive symptoms than non-Hispanic Whites and Blacks.

The natural course of spinal cord injury: changes over 40 years among those with exceptional survival

OBJECTIVES

To identify 40-year longitudinal changes in health, activity, employment, life satisfaction and self-rated adjustment after spinal cord injury.

STUDY DESIGN

Longitudinal, mailed self-report.

METHODS

Participants were identified from outpatient records of a Midwestern USA university hospital in 1973. Follow-ups were conducted in 1984 and approximate 10-year intervals thereafter. A total of 49 participants completed each of the five assessments. Data were reviewed and analyzed by research team members and a research associate with experience in biostatistics at a medical university in Southeastern USA. Life Situation Questionnaire included the following: (1) demographic and injury characteristics, (2) educational status and employment, (3) community participation, (4) life satisfaction, (5) adjustment, and (6) recent medical history.

RESULTS

Proportion of individuals with 10+ non-routine physician visits increased from consistently <10% to >40% during the 40 years. Proportion who spent a week or more in hospital increased from a low of 10% at 20-year follow-up to 43% at 40-year follow-up. Percentage employed and average hours employed initially improved over time but decreased substantially during the last two times of measurement. Satisfaction with health, sex life and social life declined over time, whereas satisfaction with employment improved initially and was maintained over time. Self-rated current adjustment remained stable, whereas predicted future adjustment declined steadily over 40 years.

CONCLUSIONS

Age-related declines were apparent for need of physician visits and hospitalizations, with notable declines in satisfaction with sex life, social life and health. However, not all indices declined over time. Participants appeared to maintain stability when rating their own adjustment.

Prevalence of mood disturbance in Australian adults with chronic spinal cord injury

BACKGROUND

There is little understanding of the prevalence of mental health issues in people with spinal cord injury (SCI) after they leave rehabilitation or how mental health issues can alter over time.

AIM

The aims were to (i) determine the prevalence of mood disturbance in adults with chronic SCI living in the community, (ii) ascertain whether the prevalence of mood disturbance had changed since a previous study in 2004-2005 and (iii) establish whether people with chronic SCI remain vulnerable to mood disturbance, irrespective of time since injury.

METHODS

Prospective, open-cohort case series. Participants were 573 community-based adults with a chronic SCI. The depression, anxiety and stress scale - short version was used. Analyses included simple descriptors, Chi-squared and repeated measures t-tests.

RESULTS

Nearly half of participants (n = 263/573; 46%) reported symptoms indicating mood disturbance, which was similar to the level found in the previous study. While the presence of mood disturbance persisted in 23% of adults (n = 26) and 46 (41%) were in the 'below threshold' category, just over a third of the adults who participated in both studies (n = 111) experienced a change (n = 21, 19% mood disturbance resolved and n = 18, 16% mood disturbance developed).

CONCLUSION

Both resilience and change are common. At no time after SCI is the risk of mental health problems considered reduced or even stable. These results highlight the importance of regular mental health reviews even in those who have previously displayed good resilience.

Wheelchair use in ultra-lightweight wheelchair users

PURPOSE

The goal of this study was to describe how ultra-lightweight wheelchair users use their wheelchairs during everyday mobility.

METHOD

We instrumented a convenience sample of 69 ultra-lightweight wheelchair users with a seat switch to measure their occupancy, and an accelerometer on their wheel to measure distance wheeled, time spent wheeling and daily bouts of mobility.

RESULTS

On the median day, subjects wheeled 83 bouts and 1.4 km over 45 min. A typical bout of mobility was 8.3 m in length, lasting 20 s and occurring at a speed of 0.44 m/s. Fast (>1 m/s) and long (>2 min) bouts represented less than 4% of bouts and were more common among younger participants and those who were employed or a student.

CONCLUSIONS

Highly functional manual wheelchair users present with a significant mobility disability, moving far less than their ambulating peers despite moving with similar mobility characteristics. The typical bout characteristics - short and slow bouts - are consistent with indoor mobility and transitions between functional activities. For wheelchair users, it highlights the importance of manoeuverability and the need for prescription and training to emphasize manoeuverability. Implications for Rehabilitation Measurement of wheelchair use, both how and how much, might provide unique insight to what equipment would be most appropriate for an individual. Participants who used an ultralight wheelchair presented with a significant mobility disability, wheeling only 1.7 km/day on average. Fast (>1 m/s) and long (>2 min) bouts are uncommon, representing less than 4% of bouts. Younger participants and those who were employed or a student were more likely to wheel one fast and long bout per day. Because wheelchair mobility was dominated by short, slow bouts, prescription and training need to emphasize maneuverability.

Why stay home? Temporal association of pain, fatigue and depression with being at home

BACKGROUND

Community participation is important to most people with disabilities despite the fact that common secondary conditions like pain, fatigue and depression may increase the difficulty of leaving home. Despite decades of research on these secondary conditions, little is known about how they are associated with being at home.

OBJECTIVE

We used Ecological Momentary Assessment data to examine within subject fluctuation in these secondary conditions to examine their effect on the likelihood that participants remain at or return home.

METHODS

Participants (n = 139) were recruited from a population based sampling frame to complete an Ecological Momentary Assessment that queried their location and experience with secondary conditions six times a day for two weeks.

RESULTS

Between subjects secondary condition ratings averaged across time periods indicated that pain and depression were associated with the share of measurement periods that respondents reported being at home. Within subject results indicated that a standard unit increase in pain, fatigue and depression was associated with being home one to two days later. Within day results indicated that increases in pain and fatigue were associated with increased likelihood of being home later, but increases in depression were associated with lower likelihood of being home later.

CONCLUSION

These results suggest there may be a complicated relationship among these secondary conditions and community participation with effects observed both across and within days. One interpretation suggests that secondary condition severity is tempered by adjusting participation. These results may have implications for intervening on these secondary conditions.

SCI Longitudinal Aging Study: 40 Years of Research

BACKGROUND

The Spinal Cord Injury (SCI) Longitudinal Aging Study was initiated in 1973 and has conducted 8 assessments over the past 40 years. It was designed to help rehabilitation professionals understand the life situation of people with SCI, but it has developed into the most long-standing study of aging and SCI and has resulted in over 50 publications.

OBJECTIVE

Our purpose was to provide a detailed history of the study, response patterns, utilization of measures, and a summary of key findings reported in the literature.

METHODS

Five participant samples have been incorporated over the 40 years, with enrollment in 1973, 1984, 1993 (2 samples), and 2003. A total of 2,208 participants have completed 6,001 assessments, with a particularly large number of assessments among those who are more than 40 years post injury (n = 349).

RESULTS

The overall results have indicated changing patterns of outcomes over time as persons with SCI age, with some notable declines in participation and health. There has been a survivor effect whereby persons who are more active, well-adjusted, and healthier live longer.

CONCLUSIONS

This study has several important features that are required for longitudinal research including (a) consistency of follow-up, (b) consistency of measures over time, (c) addition of new participant samples to counteract attrition, and (d) inclusion of a large number of individuals who have reached aging milestones unparalleled in the literature. Data from this study can inform the literature on the natural course of aging with SCI.

Measuring positive affect and well-being after spinal cord injury: Development and psychometric characteristics of the SCI-QOL Positive Affect and Well-being bank and short form

OBJECTIVE

To develop an item response theory (IRT)-calibrated spinal cord injury (SCI)-specific Positive Affect and Well-being (PAWB) item bank with flexible options for administration.

DESIGN

Qualitative feedback from patient and provider focus groups was used to expand on the Neurological Disorders and Quality of Life (Neuro-QOL) positive affect & well-being item bank for use in SCI. New items were created and revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis, graded response IRT modeling and evaluation of differential item functioning (DIF).

SETTING

We tested a 32-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital.

PARTICIPANTS

A total of 717 individuals with SCI answered the PAWB questions.

RESULTS

A unidimensional model was observed (Confirmatory Fit Index=0.947; Root Mean Square Error of Approximation=0.094) and measurement precision was good (reliability in theta of -2.9 to 1.2 is roughly equivalent to classical reliability of 0.95 or above). Twelve items were flagged for DIF, however, after examination of effect sizes, the DIF was determined to be negligible and would have little practical impact on score estimates. The final calibrated item bank resulted in 28 retained items

CONCLUSIONS

This study indicates that the Spinal Cord Injury--Quality of Life PAWB bank represents a psychometrically robust measurement tool. Short form items are also suggested and a computer adaptive test is available.

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

OBJECTIVE

To describe the development and psychometric properties of the Spinal Cord Injury--Quality of Life (SCI-QOL) Resilience item bank and short form.

DESIGN

Using a mixed-methods design, we developed and tested a resilience item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory based analytic approaches, including tests of model fit and differential item functioning (DIF).

SETTING

We tested a 32-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs medical center.

PARTICIPANTS

A total of 717 individuals with SCI completed the Resilience items.

RESULTS

A unidimensional model was observed (CFI=0.968; RMSEA=0.074) and measurement precision was good (theta range between -3.1 and 0.9). Ten items were flagged for DIF, however, after examination of effect sizes we found this to be negligible with little practical impact on score estimates. The final calibrated item bank resulted in 21 retained items.

CONCLUSION

This study indicates that the SCI-QOL Resilience item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available.

Effects of Adult Romantic Attachment and Social Support on Resilience and Depression in Individuals with Spinal Cord Injuries

BACKGROUND

Spinal cord injury (SCI) can cause psychological consequences that negatively affect quality of life. It is increasingly recognized that factors such as resilience and social support may produce a buffering effect and are associated with improved health outcomes. However the influence of adult attachment style on an individual's ability to utilize social support after SCI has not been examined.

OBJECTIVE

The purpose of this study was to examine relationships between adult romantic attachment perceived social support depression and resilience in individuals with SCI. In addition we evaluated potential mediating effects of social support and adult attachment on resilience and depression.

METHODS

Participants included 106 adults with SCI undergoing inpatient rehabilitation. Individuals completed measures of adult attachment (avoidance and anxiety) social support resilience and depression. Path analysis was performed to assess for presence of mediation effects.

RESULTS

When accounting for the smaller sample size support was found for the model (comparative fit index = .927; chi square = 7.86, P = .01; β = -0.25, standard error [SE] = -2.93, P < .05). The mediating effect of social support on the association between attachment avoidance and resilience was the only hypothesized mediating effect found to be significant (β = -0.25, SE = -2.93, P < .05).

CONCLUSIONS

Results suggest that individuals with SCI with higher levels of attachment avoidance have lower perceived social support which relates to lower perceived resilience. Assessing attachment patterns during inpatient rehabilitation may allow therapists to intervene to provide greater support.

Comparison of mental health between individuals with spinal cord injury and able-bodied controls in Neiva, Colombia

Although research has investigated the mental health of individuals with spinal cord injury (SCI), an overwhelming majority of this research has been conducted in the United States, Western Europe, and other developed countries. The purpose of this study was to compare the mental health of individuals with SCI with able-bodied controls in Neiva, Colombia, South America. Subjects included 40 Colombians with SCI and 42 age- and sex-matched controls (N = 82). The groups did not differ based on age, sex, years of education, or socioeconomic status. However, controls were twice as likely to be married. Four measures assessed mental health, including satisfaction with life (Satisfaction with Life Scale), depressive symptoms (Patient Health Questionnaire-9), self-esteem (Rosenberg Self-Esteem Scale), and anxiety (State-Trait Anxiety Inventory). In comparison with able-bodied controls, individuals with SCI reported significantly lower mental health on both depressive symptoms and satisfaction with life. These effect sizes were medium and large, respectively. The groups did not differ significantly on measures of self-esteem or anxiety. Mental health of individuals with SCI should be considered a central part of SCI rehabilitation interventions, particularly in Latin America.

Mediating effects of social support and self-concept on depressive symptoms in adults with spinal cord injury

STUDY DESIGN

Cross-sectional, correlational design.

OBJECTIVES

To examine the effects of individual demographics, activities of daily living, social support, and self-concept on depressive symptoms in people with spinal cord injury (SCI).

SETTING

A convenience sample of 135 adults with SCI was recruited from medical and rehabilitation centres in Taiwan.

METHODS

Face-to-face, structured interviews were employed to collect information. Study questionnaires included a demographic sheet, the Barthel scale, the modified Social Support Inventory, the Huang self-concept scale and the Beck Depression Inventory. Data were analysed by structural equation modelling (SEM).

RESULTS

The average age of the participants was 43.3 years (±11.98), the mean duration of injury was 114 months (±93.78), and most were males. Emotional support (r=-0.173, P<0.05) and appraisal support (r=-0.261, P<0.01) were negatively correlated with depressive symptoms. The best fitted SEM model included individual demographics and physical function, social support and self-concept as significant predictors of depressive symptoms, with self-concept acting as a mediator in this relationship. Participants' characteristics and social support both contributed substantial indirect effects on depressive symptoms via self-concept. Self-concept also mediated the relationship between education, income, physical functioning and participants' depressive symptoms.

CONCLUSION

For this sample, the more negative that individuals perceived themselves, the more likely they were to report worsening depressive symptoms. The more social support that individuals have, the more likely they were to report less depressive symptoms. Further longitudinal research will help clarify the direction of these relationships.

Pain and fatigue as mediators of the relationship between mobility aid usage and depressive symptomatology in ambulatory individuals with SCI

STUDY DESIGN

Cross-sectional cohort study.

OBJECTIVES

To investigate a mediational model where pain (intensity and interference) and fatigue mediate the relationship between the use of mobility aids and moderate-to-severe depressive symptomatology among ambulatory participants with spinal cord injury (SCI).

SETTING

A medical university in the southeastern United States.

METHODS

Ambulatory adults (N=652) with chronic SCI responded to a mail-in survey. The Patient Health Questionnaire-9 was used to assess moderate-to-severe depressive symptomatology. The Brief Pain Inventory was used to assess pain intensity and interference, and the Modified Fatigue Impact Scale-5-item version was used to assess fatigue. Participants self-reported use of mobility aids.

RESULTS

On examining mobility aids used for ambulation, 65% were found to have used at least one aid. Severe pain intensity was reported by 11%, and 14% reported severe pain interference. Disabling fatigue was reported by 10% of the participants. Twenty-one percent (n=138) reported moderate-to-severe levels of depressive symptoms. On examining the relationships between mobility aids and depressive symptomatology, using people as a mobility aid was associated with increased odds of depressive symptomatology (2.6) and always using a wheelchair was associated with lower odds (0.3). However, these relationships were no longer significant after controlling for the mediating variables pain intensity, pain interference and fatigue.

CONCLUSIONS

Pain and fatigue mediate the relationship between usage of certain mobility aids and depressive symptomatology. The use of people to assist in ambulation is associated with greater odds of moderate-to-severe depressive symptomatology, while always using a wheelchair is associated with lower odds.

Symptoms of depression over time in adults with pediatric-onset spinal cord injury

OBJECTIVE

To investigate the prevalence of depressive symptoms in adults with pediatric-onset spinal cord injury (SCI) and explore potential risk factors that may be associated with elevated symptoms.

DESIGN

Longitudinal, cohort survey over a period of 2 to 9 years. Follow-up occurred approximately every year, a total of 868 interviews were conducted, and most participants contributed to at least 3 waves of data (72%; range, 2-8; mean, 4.34±2.16).

SETTING

Community.

PARTICIPANTS

Adults (N=214; 133 men; mean age at first interview, 29.52±5.21y; range, 24-42y) who sustained an SCI prior to age 19 (mean age at injury, 13.93±4.37y; range, 0-18y). Participants tended to have complete injuries (71%) and tetraplegia (58%).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Participants completed measures assessing psychosocial functioning, physical independence, participation, and depression at each time point. Multilevel growth modeling analyses were used to explore depression symptoms across time.

RESULTS

Depression symptoms at initial status were typically minimal (3.07±.24; 95% confidence interval, 2.6-3.54) but fluctuated significantly over time (P<.01). Several factors emerged as significant predictors of depressive symptoms in the final model, including less community participation (P<.01), incomplete injury (P=.02), hazardous drinking (P=.02), bladder incontinence (P=.01), and pain (P=.03). Within individuals, as bowel accidents (P<.01) and pain increased (P<.01), depression scores increased; however, marriage resulted in decreases in depression scores for individuals (P=.02).

CONCLUSIONS

These findings suggest that most patients with pediatric-onset SCI are psychologically resilient, but strategies to minimize secondary health complications and foster community participation and engagement should be considered.

Evaluating a spinal cord injury-specific model of depression and quality of life

OBJECTIVES

To determine whether demographic, injury, health, and functional factors similarly have the same predictive relation with both somatic and nonsomatic symptoms of depression, as well as whether somatic and nonsomatic symptoms of depression have the same association with quality of life (QOL).

DESIGN

Secondary analysis of cross-sectional survey data.

SETTING

Community

PARTICIPANTS

Patients with traumatic spinal cord injury (N=4976) who completed an interview at 1 year postinjury between 2006 and 2011.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Somatic and nonsomatic symptoms of depression from the Patient Health Questionnaire-9 and QOL measured by the Satisfaction With Life Scale.

RESULTS

Structural equation modeling showed that the hypothesized model provided a good fit to the data, but modification of the model led to a significant improvement in model fit: Δχ(2)(1)=226.21, P<.001; comparative fit index=.976; χ(2)(199)=585.39, P<.001; root mean square error of approximation=.027 (90% confidence interval, .025-.030). The health-related factors including pain severity, pain interference, and health status were similarly associated with both somatic and nonsomatic symptoms of depression. QOL was negatively associated with nonsomatic symptoms of depression but was unrelated to somatic symptoms of depression.

CONCLUSIONS

Assessment of depression after spinal cord injury should include a careful assessment of health concerns given the relation between health-related factors and both somatic and nonsomatic symptoms of depression. Treatments of depressive symptoms may be improved by targeting health concerns, such as pain, along with a specific focus on nonsomatic symptoms to improve the QOL.
