The relationship between posttraumatic stress disorder following spinal cord injury and locus of control

Cognitive, behavioral and psychiatric symptoms in patients with spinal cord injury: a scoping review

Spinal Cord Injury (SCI) is a condition where the spinal cord is damaged and experiences partial or complete loss of motor and/or sensory function, which is typically less than normal. After SCI, patients may exhibit more severe psychiatric symptoms and experience cognitive impairments, including reduced speed and attention processing capacity, as well as difficulties with executive function and episodic memory retention. Among the behavioral and psychiatric symptoms, depression, anxiety, substance use disorder, and posttraumatic stress disorder are the most common. This review aims to investigate the cognitive, behavioral, or psychiatric symptoms of the patient with SCI and their influence on the rehabilitation process. Studies were identified from an online search of PubMed, Web of Science, Cochrane Library, and Embase databases. Studies published between 2013-2023 were selected. This review has been registered on OSF (n) 3KB2U. We have found that patients with SCI are at high risk of cognitive impairment and experience a wide range of difficulties, including tasks based on processing speed and executive function. This clinical population may experience adjustment disorders with depression and anxiety, as well as other psychiatric symptoms such as fatigue, stress, and suicidal ideation. This review has demonstrated that SCI patients may experience psychiatric symptoms and cognitive impairments that affect their functioning. At the same time, these patients may be more prone to various adjustment and mood disorders. Moreover, these two aspects may interact with each other, causing a range of symptoms, increasing the risk of hospitalization, and delaying the rehabilitation process.

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.

Using Cognitive Bias Modification-Appraisal Training to Manipulate Appraisals about the Self and the World in Analog Trauma

Background

Dysfunctional appraisals are a key mechanism in posttraumatic stress disorder (PTSD). Experimental manipulations of appraisals via Cognitive Bias Modification-Appraisal (CBM-App) training targeting cognitions related to the ‘self’ has shown to affect analog trauma symptoms. The present study aimed to conceptually replicate and extend previous findings by comparing a newly developed ‘world’ to the original ‘self’ training, and investigate the moderating role of locus of control (LOC) on intrusions.

Methods

Healthy participants (N = 173) were exposed to distressing films as an analog trauma induction. Next, participants received positive or negative CBM-App, targeting either self- or world-relevant appraisals. Dysfunctional appraisals and LOC were assessed pre- and post-training. During the week after the laboratory session, participants recorded their intrusions and associated distress in a diary. One week later, trauma-relevant symptomatology was assessed.

Results

Positive compared to negative CBM-App induced training-congruent appraisals, independent of the trained cognition (self vs. world). However, there was no effect on analog trauma symptoms and LOC did not moderate the training’s effect.

Conclusions

Our results underline the validity of CBM-App as a method to experimentally manipulate appraisals. However, since we did not fully replicate previous findings further research on mechanisms associated with transfer effects is warranted.

Post-traumatic stress disorder symptoms and pain intensity in persons with spinal cord injury

STUDY DESIGN

Cross-sectional.

OBJECTIVES

To examine the association between post-traumatic stress disorder (PTSD) symptoms and pain intensity, taking symptoms of anxiety and depression into account within persons with spinal cord injury (SCI).

SETTING

Persons with SCI, who visited a Dutch rehabilitation centre between 2005 and 2010, were invited to complete a survey.

METHODS

PTSD symptoms were measured with the Trauma Screening Questionnaire (TSQ), pain intensity with an 11-point Numerical Rating Scale (NRS), and symptoms of anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). To determine associations between PTSD symptoms and pain intensity, linear regression analyses were performed. Confounding variables representing anxiety and depression were added to the final model.

RESULTS

In total, 175 participants (55.8% traumatic, 29.1% complete) were included (response rate of 31.7%). Of them, 11.4% had clinically relevant symptoms of probable PTSD (TSQ score ≥ 6) 69.8% experienced moderate to severe pain levels (NRS ≥ 4), 14.9% had symptoms of anxiety and 20.8% symptoms of depression (HADS scores ≥ 11). Levels of PTSD symptoms were strongly associated with symptoms of anxiety (0.54) and depression (0.49). Bivariate analyses showed a moderate significant association (0.30) between PTSD symptoms and pain intensity. This association became small (0.10) when anxiety and depression comorbidity were factored into the final regression model.

CONCLUSIONS

No independent association between PTSD symptoms and pain intensity was shown when adjusted for anxiety and depression. Results of this study suggest the usefulness of screening for PTSD in persons with SCI (regardless of injury cause or type/level) who score high on symptoms of anxiety/depression.

Spinal cord injury by clip-compression induces anxiety and depression-like behaviours in female rats: The role of the inflammatory response

Traumatic spinal cord injury (SCI) promotes long-term disability that affects mobility and functional independence. The spinal cord inflammatory response after the initial mechanical insult substantially impacts locomotor impairment and development of neuropsychiatric disorders, including anxiety and depression. However, these psychiatric events are scarcely investigated in females. This study investigated the anxiety/depression-like behaviours and inflammatory responses related to the production/release of pro- and anti-inflammatory cytokines in female adult Wistar rats submitted to severe clip-compression SCI. Data showed that SCI impaired the locomotor performance assessment by the BBB scale, but did not alter exploratory activity in open-field test. Animals' locomotor impairment was associated with anxious and depressive-like behaviours characterised by a decreased amount of time in the open arms of the elevated plus-maze test, and the motivational reduction of social interaction and anhedonia assessed by social exploration and sucrose preference tests. By contrast, SCI decreased the immobility time in the forced swimming test. Moreover, SCI caused a significant increase in local and systemic proinflammatory cytokines (TNF-α, INF-γ, IL-1β, and IL-6) and a reduction in the anti-inflammatory cytokine IL-10. Finally, there were significant negative correlations between depression-like behaviour, but not anxiety, and increased plasma concentrations of TNF-α, IL-1β, IL-6, and INF-γ. Additionally, the laminectomy procedure provoked the inflammatory response associated with reduced sucrose intake in Sham animals, although less expressively than in the SCI group. Collectively, these results indicate that SCI by clip-compression in female rats promotes a neuropsychiatric-like profile associated with an imbalance in the production/release of pro- and anti-inflammatory cytokines.

Locus of control in US combat veterans: Unique associations with posttraumatic stress disorder 5-factor model symptom clusters

Given elevated rates of posttraumatic stress disorder (PTSD) among US military veterans, identifying correlates of PTSD and specific PTSD symptom clusters that best represent PTSD in veterans (i.e., the five-factor Dysphoric Arousal model) is critical to prevention and intervention efforts. One potential correlate is locus of control (i.e., the extent to which individuals believe they have control over events in their lives). The aim of this study was to examine the relations between locus of control and five-factor model PTSD symptom clusters (i.e., re-experiencing, avoidance, numbing, dysphoric arousal, anxious arousal) among combat veterans. Eighty-nine combat exposed veterans completed self-report measures of demographics, locus of control, PTSD symptoms, and combat exposure. Bivariate correlations indicated relations between locus of control and overall PTSD symptoms, avoidance symptoms, and numbing symptoms. When controlling for sex and combat exposure in regression analyses, only avoidance remained a significant correlate of locus of control. Among veterans with the most extreme scores (n = 26), external locus of control predicted overall PTSD symptoms and avoidance symptoms. External locus of control is uniquely associated with avoidance symptoms, and represents a potentially modifiable factor to address in trauma-focused treatments.

Posttraumatic stress disorder following asthma attack: the role of agency beliefs in mediating psychiatric morbidity

BACKGROUND

The link between serious illness and subsequent posttraumatic stress disorder (PTSD) and psychiatric comorbidity has been established. In populations with asthma, however, few studies have investigated this link, or what psychological mechanisms mediate it. Healthcare guidance for chronic conditions, and PTSD literature, highlight "agency beliefs" as a direction for investigation.

AIMS

To determine the prevalence of PTSD following asthma attack, and investigate whether agency beliefs mediate PTSD and comorbid psychiatric symptoms in this population.

METHOD

We recruited 110 adults with asthma from online peer support forums. Participants completed the Asthma Symptom Checklist, PTSD Checklist, GHQ-28, General Self-Efficacy scale, and Multidimensional Health Locus of Control scale.

RESULTS

20% of our sample met criteria for PTSD. Regression results indicated that higher asthma severity significantly predicted PTSD and psychiatric co-morbidity. Lower self-efficacy significantly predicted PTSD symptoms while controlling for asthma severity, however Locus of Control (LoC) did not improve the model further. Self-efficacy, but not LoC, significantly partially mediated the effect of asthma severity on PTSD severity and psychiatric co-morbidity.

CONCLUSIONS

PTSD and other psychiatric symptoms in asthma populations are mediated in part by self-efficacy. Safeguarding and improving self-efficacy in this population is an important area for future research and intervention.

Independent sailing with high tetraplegia using sip and puff controls: integration into a community sailing center

BACKGROUND

We are continually rediscovering how adapted recreational activity complements the rehabilitation process, enriches patients' lives and positively impacts outcome measures. Although sports for people with spinal cord injuries (SCI) has achieved spectacular visibility, participation by high cervical injuries is often restricted due to poor accessibility, safety concerns, lack of adaptability, and high costs of technology.

METHODS

We endeavor to demonstrate the mechanisms, adaptability, accessibility, and benefits the sport of sailing creates in the rehabilitative process. Our sailor is a 27-year-old man with a history of traumatic SCI resulting in C4 complete tetraplegia.

RESULTS

The participant completed an adapted introductory sailing course, and instruction on the sip-and-puff sail and tiller control mechanism. With practice, he navigated an on-water course in moderate winds of 5 to 15 knots.

DISCUSSION

Despite trends toward shorter rehabilitation stays, aggressive transdisciplinary collaboration with recreation therapy can provide community and natural environment experiences while inpatient and continuing post discharge. Such peak physical and psychological experiences provide a positive perspective for the future that can be shared on the inpatient unit, with families and support systems like sailing clubs in the community.

CONCLUSION

Rehabilitation theory directs a team process to achieve patient self-awareness and initiate self-actualization in spite of disablement. Utilization of local community sailing centers that have provided accessible assisted options provides person-centered self-realization of goals as assisted by family and natural supports. Such successful patients become native guides for others seeking the same experience.

Event centrality as a unique predictor of posttraumatic stress symptoms and perceived disability following spinal cord injury

STUDY DESIGN

We conducted a cross-sectional study involving completion of self-report measures.

OBJECTIVES

Individuals who acquire a spinal cord injury (SCI) face numerous physical and psychological challenges, with the former receiving considerable less attention during the rehabilitation process. In this article, we examined event centrality as a unique predictor of psychological outcomes in a sample of individuals receiving rehabilitation for SCI. Event centrality refers to the extent to which individuals construe a stressful experience as a core part of their identity. In samples of individuals exposed to psychological traumas (for example, sexual assault or military combat), event centrality has emerged as a consistent and powerful predictor of posttraumatic stress symptoms (PTSSs). This is the first study to examine event centrality in an SCI sample.

SETTING

Inpatient rehabilitation program in a large urban city in the Southwestern United States.

METHODS

A sample of 55 participants in rehabilitation for a recent SCI completed measures of event centrality, PTSS, depressed mood and perceived disability.

RESULTS

Event centrality was significantly related to perceived disability (r=0.48) and PTSS (r=0.31) and accounted for unique variance in these two outcomes after controlling for demographics and depressed mood.

CONCLUSION

Event centrality is common among individuals with SCI and may be a unique contributor to worse psychological and functional outcomes. We hope our findings will alert health-care professionals to the importance of event centrality.

Posttraumatic stress following spinal cord injury: a systematic review of risk and vulnerability factors

OBJECTIVES

To summarise quantitatively the available evidence relating to pretraumatic, peritraumatic and posttraumatic characteristics that may increase or decrease the risk of developing posttraumatic stress disorder (PTSD) following spinal cord injury (SCI).

STUDY DESIGN

Systematic review.

METHODS

Seventeen studies were identified from the PubMed, PsycInfo, Embase, Scopus, CINAHL, Web of Science and PILOTS databases. Effect size estimates (r) with associated 95% confidence intervals (CIs), P-values and fail-safe Ns were calculated.

RESULTS

Individual studies reported medium-to-large associations between factors that occurred before (psychiatric history r=0.48 (95% CI, 0.23-0.79) P=0.01) or at the time of injury (tetraplegia r=-0.36 (95% CI, -0.50 to -0.19) P<0.01). Postinjury factors had the strongest pooled effects: depressed mood (r_w=0.64, (95% CI, 0.54-0.72)), negative appraisals (r_w=0.63 (95% CI, 0.52-0.72)), distress (r_w=0.57 (95% CI, 0.50-0.62)), anxiety (r_w=0.56 (95% CI, 0.49-0.61)) and pain severity (r_w=0.35 (95% CI, 0.27-0.43)) were consistently related to worsening PTSD symptoms (P<0.01). Level of injury significantly correlated with current PTSD severity for veteran populations (Q_B (1)=18.25, P<0.001), although this was based on limited data.

CONCLUSION

Combinations of peri- and post-injury factors appear to be influential in the development of PTSD among persons with SCI. Further studies are needed to extrapolate these findings to the broader spinal cord-injured population. More longitudinal research, driven by multicausal models of causation such as the diathesis-stress model, is also needed to determine the temporality of PTSD risk factors.

Psychological impact of injuries sustained in motor vehicle crashes: systematic review and meta-analysis

OBJECTIVE

The aim of this meta-analysis was to determine the psychological impact associated with motor vehicle crash (MVC)-related physical injuries.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Multiple search engines included MEDLINE (via OVID), PsycINFO and Embase, and studies were sourced from scientific journals, conference papers and doctoral theses.

STUDY SELECTION

A high-yield search strategy was employed. Terms like 'psychological distress', 'depression', 'PTSD' and 'motor vehicle accident' were employed. These key words were run primarily and secondary searches were then conducted in association with the major injury types. Studies needed to compare psychological distress in people injured in an MVC with uninjured controls who had not recently experienced an MVC.

DATA EXTRACTION

Searches resulted in the identification of 2537 articles, and after eliminating duplicates and studies not meeting inclusion criteria, 24 studies were selected involving 4502 injured participants. These studies were entered into separate meta-analyses for mild to moderate traumatic brain injury (mTBI), whiplash-associated disorder (WAD) and spinal cord injury (SCI).

RESULTS

Elevated psychological distress was associated with MVC-related injuries with a large summary effect size in WAD (0.90), medium to large effect size in SCI (0.69) and small to medium effect size in mTBI (0.23). No studies meeting inclusion criteria were found for burns, fractures and low back injury. Increased psychological distress remains elevated in SCI, mTBI and WAD for at least 3 years post-MVC.

CONCLUSIONS

Rehabilitation strategies are needed to minimise distress subsequent to MVC-related physical injuries and the scientific robustness of studies requires improvement.

Anxiety prevalence following spinal cord injury: a meta-analysis

STUDY DESIGN

Meta-analysis.

OBJECTIVES

Prevalence estimates indicate that anxiety following spinal cord injury (SCI) is a common problem. However, methodological differences between studies may impact the clinical interpretation of these data.

METHODS

Data from 18 independent studies (Nparticipants=3158), which reported the prevalence of an anxiety disorder or associated symptoms, were identified from the Embase, PubMed and PsycInfo databases. Proportions were the primary effect size estimate. Confidence intervals, fail-safe Ns and the I(2) statistic were additionally calculated to identify the extent to which findings were robust and consistent across studies.

RESULTS

Five per cent of participants met the criteria for either GAD or panic disorder, with Agoraphobia identified in 2.5%. These diagnostic data were, however, limited to two studies. Higher rates were noted for self-reported 'caseness' of anxiety, with 27% reporting clinically significant symptoms. Anxiety prevalence estimates varied across the individual self-report measures (range: 15-32%). Method of administration (range: 26-32%) did not impact significantly on these estimates nor did recruitment source, with similarly high anxiety levels reported by hospital (27%) and community (29%) samples.

CONCLUSIONS

Early identification and treatment of anxiety are important in SCI rehabilitation, with a subgroup of individuals experiencing chronic symptoms. Further research is needed to establish guidelines for the interpretation of self-report data, including the use of clinical cutoffs.

Measuring psychological trauma after spinal cord injury: Development and psychometric characteristics of the SCI-QOL Psychological Trauma item bank and short form

OBJECTIVE

To describe the development and psychometric properties of the SCI-QOL Psychological Trauma item bank and short form.

DESIGN

Using a mixed-methods design, we developed and tested a Psychological Trauma item bank with patient and provider focus groups, cognitive interviews, and item response theory based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision.

SETTING

We tested a 31-item pool at several medical institutions 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 Veterans Administration hospital.

PARTICIPANTS

A total of 716 individuals with SCI completed the trauma items

RESULTS

The 31 items fit a unidimensional model (CFI=0.952; RMSEA=0.061) and demonstrated good precision (theta range between 0.6 and 2.5). Nine items demonstrated negligible DIF with little impact on score estimates. The final calibrated item bank contains 19 items

CONCLUSION

The SCI-QOL Psychological Trauma item bank is a psychometrically robust measurement tool from which a short form and a computer adaptive test (CAT) version are available.

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.

Risk factors for posttraumatic stress disorder in persons with spinal cord injury

PURPOSE

Many of the events that cause spinal cord injury (SCI) are traumatic events that can result in posttraumatic stress disorder (PTSD). It therefore appears that most persons with SCI are at risk for developing PTSD. This study retrospectively examined risk factors for PTSD symptoms in a sample of 71 persons with SCI.

METHOD

The Structured Clinical Interview for DSM-IV was used to assess full and partial PTSD diagnoses. Self-administered questionnaires were used to measure potential risk factors.

RESULTS

Results indicated that 11% of the participants met the criteria for full PTSD, and an additional 20% met the criteria for partial PTSD at some point after their SCI. Hierarchical linear regression analyses revealed that trauma history, peritraumatic reactions, and intolerance of uncertainty predicted the number of PTSD symptoms.

CONCLUSION

This study highlights the importance of trauma history, peritraumatic reactions, and intolerance of uncertainty in the development of PTSD symptoms. Patients at risk for PTSD should be identified early in the rehabilitation process and could benefit from psychological interventions with the aim of preventing PTSD development.

Psychosocial issues in spinal cord injury: a review

STUDY DESIGN

Review.

OBJECTIVES

To review literature on subjective well-being (SWB; mental health and life satisfaction) and on psychological and social support factors associated with these outcomes in people with spinal cord injury (SCI), in order to identify gaps in scientific knowledge and recommend research priorities.

SETTING

Non applicable.

METHODS

Narrative review of the SCI literature on life satisfaction and mental health (depression, anxiety, post-traumatic stress syndrome) outcomes in people with SCI. Further, reviews were performed of the SCI literature on psychological and social support variables associated with SWB and on psychosocial interventions aimed to improve SWB.

RESULTS

People with SCI experience, on average, higher levels of distress and lower levels of life satisfaction compared with the general population. Individual differences, however, are large, and most people with SCI adapt well to their condition. A set of psychological and social support factors is strongly related to SWB. Intervention studies on cognitive behavioural therapy or coping effectiveness training to improve SWB show promising results, but suffer from methodological weaknesses (for example, lack of randomization and small sample size).

CONCLUSION

There is a need for cohort studies with sufficient sample size, which include people early after onset of SCI in order to enhance our understanding of the course of mental health and well-being after SCI. Cohort studies could also identify which people are at risk for long-term impairment of SWB. Finally, intervention studies on psychosocial interventions are needed to identify which interventions may improve SWB of people with SCI.

The impact of perceptions of health control and coping modes on negative affect among individuals with spinal cord injuries

A wide range of demographic, medical, and personality and coping variables have been implicated as predictors of psychosocial outcomes following the onset of spinal cord injuries (SCI). The primary purpose of this study was to examine the role that perceptions of health control (internality, chance-determined, and other persons-determined) and coping strategies play in predicting respondents' negative affect, namely, reactions of depression and anxiety [i.e., posttraumatic stress disorder (PTSD)], as outcomes of psychosocial adaptation to disability. A second purpose was to investigate the potential role that time since injury (TSI) plays in moderating the influence of coping on psychosocial outcomes related to SCI. Ninety five survivors of SCI participated in the study by completing a battery of self-report measures. Two sets of multiple regression analyses were employed to address the study's goals. Findings indicated that after controlling the influence of gender, age, time since injury, and number of prior life traumas: (a) the use of disengagement coping successfully predicted both respondents' levels of depression and PTSD; (b) none of the perceptions of control of one's health significantly influenced psychosocial reactions to SCI, as indicated by depression and PTSD, although perceptions of chance control showed a moderate positive trend; and (c) time since injury did not moderate the relationships between coping and negative affect related to the onset of SCI. The implications of these findings to rehabilitation professionals are discussed.

The overlooked relationship between motivational abilities and posttraumatic stress: a review

How does traumatic stress change the ability to motivate oneself to achieve certain goals? How do motivational abilities influence the development and course of trauma sequelae? Few studies have focused on motivational constructs within posttraumatic stress research. From a trauma research perspective, it can be hypothesized that traumatic stress may contribute to motivational dysfunction. The main goal of the present article is to fill this gap in research by reviewing and discussing the existing trauma literature in terms of motivation-related concepts, such as self-efficacy, locus of control, self-esteem, and self-control/impulsivity. Fifty-four studies were reviewed, 10 of which were longitudinal studies. Approximately 20% of the reviews assessed whether motivational concepts predict posttraumatic stress, whereas only 8% examined the reverse relationship. With the exception of a few studies, motivational constructs seem to predict posttraumatic stress over the life span. The strongest relationships were reported for self-efficacy, followed by locus of control and self-esteem and, lastly, impulsivity/self-control. Overall, the findings of this review indicate that there is a lack of research investigating motivational factors as outcome variables following traumatic experiences. Furthermore, the need for longitudinal studies and studies with older adults is noted.

Capturing the psychologic-personal perspective in spinal cord injury

OBJECTIVE

The overall objective of this study was to illustrate a systematic approach for capturing the psychologic-personal perspective in International Classification of Functioning, Disability and Health-based comprehensive research on spinal cord injury (SCI) in terms of what and how to measure. The specific aims were to identify (1) relevant areas of research for capturing the psychologic-personal factors in a study that is planned and conceptualized according to the comprehensive context of the International Classification of Functioning, Disability and Health, using SCI as a case in point; (2) a set of domains relevant for SCI research from a psychologic-personal perspective; and (3) suitable measurement instruments that can be considered for the assessment of those identified domains based on a set of predefined guiding principles.

DESIGN

The psychologic-personal factor structure was developed based on an item pool of 1246 entries from secondary analyses of available data from SCI studies. The domain set for psychologic-personal factors was identified through reviewing the scientific literature in PubMed and PsycInfo. The set of measurement instruments was collected using available measurement reviews, searches in the literature, instrument databases, and further sources and was selected using guiding principles.

RESULTS

Forty specific psychologic-personal factors, subdivided into seven areas of research, were identified: (1) sociodemographic personal characteristics, (2) the position in the immediate social and physical context, (3) personal history and biography, (4) feelings, (5) thoughts and beliefs, (6) motives, and (7) patterns of experience and behavior. The psychologic-personal factors domain set contains both cross-cutting outcome domains, namely quality-of-life, life satisfaction, subjective well-being, and sociodemographic personal characteristics, life events, positive and negative affect, perceived stress, locus of control, self-efficacy, purpose in life, coping, lifestyle, and personality. For each of the identified domains, a pool of measurement instruments was listed, and the application of predefined guiding principles for measurement instrument selection was exemplified for self-efficacy. It resulted in the selection of the General Self-Efficacy Scale by Schwarzer and Jerusalem (Measures in Health Psychology: A User's Portfolio. Causal and Control Beliefs. pp. 35-37; 1995).

CONCLUSIONS

The results of the current article contributed to creating a transparent protocol for the Swiss Spinal Cord Injury Cohort study, coordinated by the Swiss Paraplegic Research in Nottwil, Switzerland. This article also stresses the relevance of the comprehensive approach to SCI and the consideration of the psychologic-personal perspective in this approach. The study, therefore, hopes to encourage scientists to use the International Classification of Functioning, Disability and Health and the psychologic-personal perspective as a frame of reference for their research. Furthermore, the research reported in this article can inform the World Health Organization's future development of the personal factors classification in the International Classification of Functioning, Disability and Health.

PTSD in the elderly: the interaction between trauma and aging

BACKGROUND

Because an increasingly large cohort of individuals is approaching their elderly years, there is concern about how the healthcare system will cope with the greater demands placed upon it. One area of concern is the impact of trauma and post traumatic stress disorder (PTSD) in the aged. Although several reviews have highlighted the lack of knowledge and research on the topic, there still remain gaps in the literature. Nevertheless, some recent behavioral, endocrinological and neuroimaging studies may provide new insights into the discussion. The central aims of this paper are to summarize the etiological, epidemiological and clinical aspects of PTSD, trauma, and the elderly, and to integrate this knowledge with (i) what is known about PTSD in adults, and (ii) the behavioral, hormonal and cerebral changes associated with healthy aging.

METHODS

A comprehensive search was performed with ISI Web of Science and PubMed for articles pertinent to the psychology and biology of PTSD, trauma, and the elderly.

RESULTS

There exist both significant similarities and differences between adults and elderly with PTSD concerning cognitive and biological profile. Evidence suggests that PTSD in the elderly does not follow a simple clinical trajectory.

CONCLUSIONS

PTSD in the elderly must be considered within the context of normal aging. Strong claims about an interaction between PTSD and aging are difficult to make due to sample heterogeneity, but it is clear that PTSD in this age group presents unique aspects not seen in younger cohorts. Further research must integrate their studies with the biological, psychological, and social changes already associated with the aging process.

Posttraumatic stress disorder and spinal cord injury

OBJECTIVES

To identify the prevalence of posttraumatic stress disorder (PTSD) after spinal cord injury (SCI) in a sample averaging over 2 decades postinjury at assessment. Related objectives are to confirm the factor structure, compare subscales with those reported in a nonclinical sample, and identify the relationship of PTSD with depression.

DESIGN

Survey.

SETTING

A medical university in the Southeastern United States.

PARTICIPANTS

Participants were initially identified through specialty hospitals in the Midwest and Southeastern United States. A cohort of adults (N=927) with traumatic SCI of at least 1 year duration at enrollment in 2002 to 2003 and a minimum of 7 years at the time of assessment completed the study materials.

INTERVENTIONS

Not applicable.

MAIN OUTCOMES MEASURES

PTSD was measured by the Purdue Posttraumatic Stress Disorder Scale-Revised, and depression was measured by the Patient Health Questionnaire 9-item.

RESULTS

PTSD was reported by less than 10% of the participants. Item endorsement decreased as a function of years postinjury, primarily because of low rates of endorsement among those 21 or more years postinjury. Confirmatory factor analysis did not result in an acceptable fit for subscales, item sets, or factors previously reported in the literature. Participants scored higher than a nonclinical sample (reported in the literature) on the arousal and avoidance subscales but lower on the re-experiencing subscale. Item endorsement were lower for the first set of items that relate directly to the SCI itself, with the highest item endorsement for "have difficulty remembering important aspects of event." PTSD rarely occurred in the absence of a depressive disorder.

CONCLUSIONS

PTSD does not appear to be highly prevalent in long-term SCI survivors, and endorsement of items related to re-experiencing and even recalling the injury are rare. Because SCI often is accompanied by mild traumatic brain injury, difficulty recalling the event may have an organic rather than psychologic component.

Sequelae of sexual trauma in women treated for non-trauma-related psychiatric disorders in a psychiatric hospital in Switzerland

OBJECTIVE

We sought to explore the impact of sexual trauma on symptom severity, sense of coherence, and control orientation in female psychiatric inpatients diagnosed with and admitted for non-trauma-related mental disorders.

METHODS

A sample of 31 female inpatients with a reported history of sexual trauma (two thirds abused in childhood, one third raped in adulthood) were compared with 31 female inpatients with similar sociodemographic backgrounds, matched for age and psychiatric diagnosis.

FINDINGS

Compared with the sexually nontraumatized patients, the patients with a reported history of sexual trauma were neither more symptomatic nor did they have a more severe course of illness. No significant differences were found between the two groups with regard to sense of coherence and control orientation. Patients who had been raped in adulthood rated lower than all other patients in the Meaningfulness subscale of the Sense of Coherence Scale, indicating that their belief that there is good reason to care about what happens has been affected.

CONCLUSION

Based on the dimensions assessed, female psychiatric inpatients with a reported history of sexual trauma were not found to be significantly different from female inpatients without such a history. The burden of a mental disorder ensuing from the severity of illness symptoms and illness course is probably so high that the potential impact of a sexual trauma cannot manifest.

Reactivity to daily stressors in adulthood: the importance of stressor type in characterizing risk factors

This study examined daily stressors in adults ages 18 to 89 years (M = 49.6 years) over 30 days. We examined the role of individual factors (i.e., age, self-concept differentiation [SCD], perceived control) in physical and psychological reactivity to interpersonal, network, home, and health stressors. Findings were consistent with the perspective that adults were less reactive to stress on days during which they felt in control and that younger adults and adults with high SCD were more vulnerable to stress. Age, SCD, and daily perceived control, however, interacted with one another, and findings varied by stressor type. For example, age differences in reactivity were moderated by SCD whereby older adults with low SCD were particularly resilient to home stressors. In addition, whether perceived control buffered adults' reactivity to daily stress varied by age and SCD. For example, only adults with high SCD were psychologically reactive to network stressors and this was the case only on days during which they reported experiencing low control. The findings emphasize the importance of considering the varying ways in which individual characteristics interact to influence stress reactivity to different types of stressors.

A systematic review of depression and anxiety measures used with individuals with spinal cord injury

STUDY DESIGN

A systematic review.

OBJECTIVES

To review and assess the psychometric properties of depression and anxiety instruments used with populations with spinal cord injury (SCI).

SETTING

Vancouver, Canada.

METHODS

Electronic databases were searched for papers reporting psychometric properties of depression and anxiety instruments. Pre-established criteria were used to assess the psychometric properties.

RESULTS

Thirteen papers reporting on the psychometric properties of 13 depression and anxiety instruments are used in this review, and include BDI, BSI, CESD-20, CESD-10, DASS-21, GHQ-28, HADS, Ilfeld-PSI, MEDS, PHQ-9, PHQ-9-Short, SCL-90-R, and the Zung SRS. Reliability data are available for 10 instruments, and validity results are available for 12 instruments. Evidence spanned the spectrum of evaluation criteria varying from poor to excellent. Responsiveness data are generally lacking.

CONCLUSION

Given that the reliability and validity findings range for the most part from adequate to excellent, and the large amount of work to develop cutoff scores specific for populations with SCI, at present there is no need to develop SCI-specific instruments. As psychometric properties of one measure do not clearly stand out, it is difficult to recommend the use of one over another. Overall, more psychometric data are needed, and if the instruments are to be used to evaluate treatment outcomes or change over time, responsiveness data are also required. Administering the instruments in tandem with each other and with clinical diagnostic interviews would provide valuable information, as would comparison of results to normative data specific to individuals with SCI.

Co-occurring medical and mental illness and substance use disorders among veteran clinic users with spinal cord injury patients with complexities

STUDY DESIGN

Longitudinal analysis of SCI registry merged with VHA administrative-data and Medicare claims files (FY1999-2002).

OBJECTIVES

To estimate the prevalence of mental illness (MI) and substance use disorders (SUDs) among veteran health administration (VHA) clinic users with spinal cord injuries (SCI) and examine subgroup variations by demographic, socioeconomic characteristics, and duration and level of SCI.

SETTING

VHA clinic users (N=8338) with SCI who were alive by the end of FY2002.

METHODS

ICD-9-CM codes were used to identify individual MI (anxiety disorders, bipolar, depressive disorders, psychoses, post-traumatic stress disorder (PTSD) and schizophrenia) and categories of SUDs (tobacco, alcohol and drug abuse). Chi-square tests and multinomial logistic regression were used to examine the demographic and socio-economic profile of VHA users with SCI and MI and/or SUD.

RESULTS

Over a 2-year period, 46% VHA users with SCI had either a MI or SUDs: 20% had MI only; 12% had SUD only and 14% had both. The most common MI was depressive disorder (27%) and tobacco use was highly prevalent (19%). African-Americans (versus whites) were less likely to be diagnosed with MI only. Increased duration of SCI lowered the likelihood of MI and/or SUDs. Mood and anxiety disorders were highly prevalent in veterans with SCI with chronic physical conditions such as diabetes, heart disease, hypertension, and respiratory diseases.

CONCLUSIONS

Mental illness and SUDs are highly prevalent in the VHA population with SCI and is complicated by the high rates of chronic physical conditions, presenting challenges in their healthcare management.

Psychological morbidity and spinal cord injury: a systematic review

STUDY DESIGN

A systematic review of the literature concerning the nature of the psychological morbidity in people with spinal cord injury (SCI).

OBJECTIVES

SCI is believed to place the individual at a high risk of psychological morbidity. The objective of this paper was to examine systematically the prevalence of negative psychological states in people with SCI, as well as to explore mediating and contextual factors.

METHODS

Search engines such as Medline and PsycInfo were systematically searched using specific key words, such as SCI, depression, anxiety and so on. Only studies that fulfilled certain criteria such as the use of valid measures in assessing psychological morbidity were used in the review process.

RESULTS

The systematic review revealed that clarification is still needed concerning the psychological consequences of people with SCI. However, findings suggest that approximately 30% of people with SCI are at risk of having a depressive disorder although in rehabilitation, and approximately 27% are at risk of having raised depressive symptoms when living in the community. The review also established that people with SCI have higher comparative risks of anxiety disorder, elevated levels of anxiety, feelings of helplessness and poor quality of life (QOL).

CONCLUSION

People with SCI have an increased risk of suffering debilitating levels of psychological morbidity. Future research needs to clarify the extent and nature of psychological morbidity following SCI by conducting prospective and comprehensive research in large heterogeneous samples of people with SCI during the rehabilitation phase and following reintegration into the community.

Health locus of control in patients with epilepsy and its relationship to anxiety, depression, and seizure control

OBJECTIVE

A person's health locus of control orientation is one of several factors that determine which health-related behaviors a person will perform. The aim of this study was to determine the health locus of control in patients with epilepsy and its relationship to anxiety, depression, and seizure control.

METHODS

Adults aged 18 and older who had had epilepsy for at least 1 year were recruited in either the inpatient epilepsy monitoring unit or the outpatient epilepsy clinic at Thomas Jefferson University in 2006. Patients anonymously filled out a questionnaire, which elicited data on age, sex, education, and seizure control. The Hospital Anxiety and Depression (HAD) scale was used to evaluate anxiety level and depression, and Form C of the Multidimensional Health Locus of Control (MHLC) scales was used to evaluate the health locus of control. Statistical analyses were performed using regression analyses to determine potentially significant associations.

RESULTS

Two hundred patients with a mean age of 40.3 +/- 16 participated. Patients had low mean scores on the Internal, medium mean scores on the Chance, and high mean scores on the Powerful Others MHLC subscales. Patients with epilepsy with higher Internal MHLC scores more frequently had controlled seizures. Patients with higher Powerful Others MHLC scores had higher scores on the Anxiety subscale of the HAD scale.

CONCLUSIONS

Patients with epilepsy in our study had weak perceptions of internal and strong perceptions of external health locus of control. This probably means patients with epilepsy might adapt less effectively to their illness and have lower levels of engagement in beneficial health behaviors and active coping strategies.
