An evidence-based review of the effectiveness of cognitive behavioral therapy for psychosocial issues post-spinal cord injury.

Study Design: Systematic review. Objective: To examine the evidence supporting the effectiveness of cognitive behavioral therapy (CBT) for improving psychosocial outcomes in individuals with spinal cord injury (SCI). Method: Electronic databases (MEDLINE, CINAHL, EMBASE, and PsycINFO) were searched for studies published between 1990 and October 2010. Randomized control trials (RCTs) and nonrandomized control trials (non-RCTs) utilizing a CBT intervention to improve psychosocial outcomes (depressive symptomatology, anxiety, coping, and adjustment to disability) in outpatient persons with SCI were included for review. Levels of evidence were assigned to each study using a modified Sackett scale. Effect size calculations for the interventions were provided where possible. Results: Nine studies met the inclusion criteria. The studies reviewed included two RCTs, six prospective controlled trials (PCTs) and one cohort study. All studies examined at least two groups. There is Level 1 and Level 2 evidence supporting the use of specialized CBT protocols in persons with SCI for improving outcomes related to depression, anxiety, adjustment, and coping. Conclusions: CBT holds promise as an effective approach for persons with SCI experiencing depression, anxiety, adjustment, and coping problems. As CBT may involve many different components, it is important in the future to determine which of these elements alone or in combination is most effective in treating the emotional consequences of SCI.

Antibody responses to tetanus toxoid and Haemophilus influenzae type b conjugate vaccines following autologous peripheral blood stem cell transplantation (PBSCT)

OBJECTIVE: Although there are many anecdotal reports that psychological intervention is effective in enhancing adjustment to spinal cord injury (SCI), there are little data to support this assertion. To date, reports of few longitudinal-based controlled trials that assessed psychological outcomes for SCI persons have been published. This study was conducted to determine long-term efficacy of cognitive behavior therapy during rehabilitation. DESIGN: The study employed a nonrandomized controlled trial, and measures were taken on three occasions: before, immediately after, and 12 months after treatment. SETTING, OUTCOME MEASURES, AND INTERVENTION: Anxiety, depressive mood, and self-esteem were assessed in 28 SCI persons consecutively selected on admission to hospital, who participated in specialized group cognitive behavior therapy (CBT) during rehabilitation. CONTROLS: The intervention group's responses on the measures were compared with a control group of 41 SCI persons who only received traditional rehabilitation services during their hospitalization. RESULTS: There were no overall group differences on anxiety, depressive mood, and self-esteem, although there was a trend for the treatment group to have greater levels of improvement in depression scores across time in comparison to the control group. However, those in the treatment group who reported high levels of depressive mood before the CBT treatment were significantly less depressed 1 year after injury, compared to similar persons in the control group. CONCLUSIONS: While it appears not everyone who experiences SCI needs CBT, at least in the hospital phase of their rehabilitation, those who report high levels of depressive mood benefited greatly from CBT.     

Cost effectiveness and medical cost-offset considerations in psychological service provision.

Suggests that empirical evidence has demonstrated that psychological interventions can effectively treat a wide range of child and adult health problems. The focus of this review is on costing issues associated with psychological interventions, including cost-effectiveness and cost offset (i.e., a reduction in health care costs attributable to effective intervention). Recent evidence has demonstrated that psychological interventions can be more cost-effective than optimal drug treatment. For example, although having comparable effectiveness, cognitive-behavioral treatments for panic disorder and for depression have been estimated to cost approximately one-third less than pharmacological treatment. Further, a recent meta-analysis of 91 research studies published between 1967 and 1997 found that average health care cost savings due to psychological intervention were in the range of 20-30% across studies, and 90% of the studies reported evidence of a medical cost offset. In conclusion, the evidence indicates that psychological treatments (1) can be cost-effective forms of treatment and (2) have the potential to reduce health care costs, as successfully treated patients typically reduce their utilization of other health care services.

Enhancing the scientific credibility of single-case intervention research: Randomization to the rescue.

In recent years, single-case designs have increasingly been used to establish an empirical basis for evidence-based interventions and techniques in a variety of disciplines, including psychology and education. Although traditional single-case designs have typically not met the criteria for a randomized controlled trial relative to conventional multiple-participant experimental designs, there are procedures that can be adopted to create a randomized experiment in this class of experimental design. Our two major purposes in writing this article were (a) to review the various types of single-case design that have been and can be used in psychological and educational intervention research and (b) to incorporate randomized experimental schemes into these designs, thereby improving them so that investigators can draw more valid conclusions from their research. For each traditional single-case design type reviewed, we provide illustrations of how various forms of randomization can be introduced into the basic design structure. We conclude by recommending that traditional single-case intervention designs be transformed into more scientifically credible randomized single-case intervention designs whenever the research conditions under consideration permit.

Suicide in a spinal cord injured population: its relation to functional status

OBJECTIVE: To determine the relation between functional status and risk of suicide among individuals with spinal cord injury (SCI). DESIGN: A follow-up study of all individuals who survived a traumatic SCI during the period from 1953 through 1990. SETTING: An SCI center in eastern Denmark. SUBJECTS: A total of 888 individuals with SCI, including 236 who died, 23 of whom committed suicide. MAIN OUTCOME MEASURES: Standardized Mortality Ratios (SMRs) of suicides among individuals with SCI. RESULTS: A 100% follow-up was established January 1, 1993. The total suicide rate among individuals with SCI was nearly five times higher than expected in the general population and lower for men than for women. The suicide rate doubled from an early inclusion period (1953-1971) to a later period (1972-1990). An unexpected finding was that the suicide rate in the group of marginally disabled persons was nearly twice as high as the group of functionally complete tetraplegic individuals. CONCLUSION: Given the high frequency of suicide, there is a need for increased awareness by rehabilitation staff and general practitioners regarding depression and psychological adjustment difficulties. Such conditions should be given special attention during rehabilitation and follow-up, especially among women with SCI and the marginally disabled.     

Meta-analysis of psychological interventions for chronic low back pain.

The purpose of this meta-analysis of randomized controlled trials was to evaluate the efficacy of psychological interventions for adults with noncancerous chronic low back pain (CLBP). The authors updated and expanded upon prior meta-analyses by using broad definitions of CLBP and psychological intervention, a broad data search strategy, and state-of-the-art data analysis techniques. All relevant controlled clinical trials meeting the inclusion criteria were identified primarily through a computer-aided literature search. Two independent reviewers screened abstracts and articles for inclusion criteria and extracted relevant data. Cohen's d effect sizes were calculated by using a random effects model. Outcomes included pain intensity, emotional functioning, physical functioning (pain interference or pain-specific disability, health-related quality of life), participant ratings of global improvement, health care utilization, health care provider visits, pain medications, and employment/disability compensation status. A total of 205 effect sizes from 22 studies were pooled in 34 analyses. Positive effects of psychological interventions, contrasted with various control groups, were noted for pain intensity, pain-related interference, health-related quality of life, and depression. Cognitive-behavioral and self-regulatory treatments were specifically found to be efficacious. Multidisciplinary approaches that included a psychological component, when compared with active control conditions, were also noted to have positive short-term effects on pain interference and positive long-term effects on return to work. The results demonstrated positive effects of psychological interventions for CLBP. The rigor of the methods used, as well as the results that reflect mild to moderate heterogeneity and minimal publication bias, suggest confidence in the conclusions of this review.

Communal behaviors and psychological adjustment of family caregivers and persons with spinal cord injury.

Objective: Examined the influence of mutual communal behaviors on the adjustment reported by persons with spinal cord injury (SCI) and their family caregivers. Previous research has found that persons who have a history of mutually communal behaviors in relationships may react differently to relationship changes after an acquired physical disability than dyads with few communal behaviors. Method: Family caregivers and persons with SCI were administered measures of mutual communal behaviors, depression, and life satisfaction. Structural equation modeling was used to test the relations among caregivers' communal behaviors and care recipients' communal behaviors, depression, and life satisfaction. Results: Caregiver and care recipient reports of communal behaviors were not significantly correlated. Significant paths indicated that care recipients' communal behavior scores were positively associated with their life satisfaction, and care recipients' depression was inversely associated with their life satisfaction. Caregivers' communal behavior scores were unrelated to their self-reported adjustment. Conclusions: Caregiver-care recipient dyads may differ in their perceptions of communal behaviors in their relationships. Although care recipient reports of communal behavior may be related to their life satisfaction, communal behaviors may not serve a similar function among caregivers of persons with SCI.

Family caregivers of persons with spinal cord injury: Predicting caregivers at risk for probable depression.

Objective: To determine the percentage of family caregivers of persons with spinal cord injury (SCI) with probable depression and to test the hypothesis that dysfunctional problem-solving abilities would be significantly predictive of risk status after taking into account important demographic characteristics and caregiver health. Design: Correlational and logistic regression analyses of data collected in a cross-sectional design. Participants: Eighteen men and 103 women caregivers (mean age of caregivers = 45.66 years, SD = 12.88) of individuals with SCI. Main Outcome Measure: The Inventory to Diagnose Depression. Results: Nineteen caregivers (15.7%) met criteria on the Inventory to Diagnose Depression for a major depressive disorder. A dysfunctional problem-solving style was significantly predictive of caregiver depression, regardless of the severity of physical impairment of the care recipient or the physical health of the caregiver and caregiver demographic variables. Conclusions: The percentage of caregivers with probable depressive disorder may parallel that observed among persons with SCI, using a more conservative self-report measure designed to assess symptoms associated with a depressive syndrome. Family caregivers with a dysfunctional problem-solving style and assisting individuals with more severe injuries may have probable depression.

The treatment of depression in older adults in the primary care setting: An evidence-based review.

The objective of this study was to conduct an evidence-based review of treatments for depression in older adults in the primary care setting. A literature search was conducted using PsycINFO and Medline to identify relevant, English language studies published from January 1994 to April 2004 with samples aged 55 and older. Studies were required to be randomized controlled trials that compared psychosocial interventions conducted within the primary care setting with "usual care" conditions. Eight studies with older adult samples met inclusion criteria and were included in the review. Two treatment models were evident: Geriatric Evaluation Management (GEM) clinics and an approach labeled integrated health care models. Support was found for each model, with improvement in depressive symptoms and better outcomes than usual care; however, findings varied by depression severity, and interventions were difficult to compare. Further efforts to improve research and clinical care of depression in the primary care setting for older adults are needed. The authors recommend the use of interdisciplinary teams and more implementation of psychosocial treatments shown to be effective for older adults.

Improving the quality of life of caregivers of persons with spinal cord injury: A randomized controlled trial.

Objective: To assess the efficacy of two psychosocial interventions for caregivers of older persons with spinal cord injury (SCI). Design: A multisite, three-group, randomized controlled trial comparing two active intervention conditions with each other and to an information-only control group. One hundred seventy-three caregiver and care-recipient dyads were randomly assigned to one of three conditions: a caregiver-only treatment condition in which caregivers received a multicomponent intervention based on their risk profile; a dual-target condition in which the caregiver intervention was complemented by a treatment targeting the care recipient, designed to address both caregiver and care recipient risk factors; and an information-only control condition in which the caregiver received standard printed information about caregiving, SCI, and aging. Outcome Measures: A multivariate outcome comprised of six indicators linked to the goals of the interventions was the primary outcome of the study. The multivariate outcome included measures of depressive symptoms, burden, social support and integration, self-care problems, and physical health symptoms. Results: At 12 months, caregivers in the dual-target condition had improved quality of life as measured by our multivariate outcome when compared to the control condition. Using the dyad as the unit of analysis, the dual-target condition was superior to both the control condition and the caregiver-only condition in our multivariate outcomes analysis. Dyads enrolled in the dual-target condition had significantly fewer health symptoms than control condition and caregiver-only condition participants and were less depressed when compared to participants in the caregiver-only condition. In follow-up analyses we found that a higher proportion of caregivers in the dual-target condition had clinically significant improvements in depression, burden, and health symptoms when compared with the caregiver-only condition. Conclusion: Caregivers are in need of and can benefit from interventions that help them manage the medical and functional limitations of the care recipient. Intervention strategies that target both the caregiver and care recipient are particularly promising strategies for improving the quality of life of caregivers.

Randomized controlled trial of a preventive intervention for perinatal depression in high-risk Latinas.

Objective: A randomized controlled trial was conducted to evaluate the efficacy of a cognitive–behavioral (CBT) intervention to prevent perinatal depression in high-risk Latinas. Method: A sample of 217 participants, predominantly low-income Central American immigrants who met demographic and depression risk criteria, were randomized into usual care (UC; n = 105) or an 8-week CBT group intervention during pregnancy and 3 individual booster sessions during postpartum (n = 112). Participants completed measures assessing depressive symptoms (Center for Epidemiological Studies Depression Scale at baseline; Beck Depression Inventory, Second Edition [BDI–II]) and major depressive episodes (Mood Screener) at 5 time points throughout the perinatal period. Results: Intent-to-treat analyses indicated that intervention participants had significantly lower depressive symptoms and fewer cases of moderate depression (BDI–II ≥ 20) at Time 2 than UC participants. These effects were stronger for women who fully participated in the intervention (≥4 classes). The cumulative incidence of major depressive episodes was not significantly different between the intervention (7.8%) and UC (9.6%) groups. Conclusions: A CBT intervention for low-income, high-risk Latinas reduced depressive symptoms during pregnancy but not during the postpartum period. Low levels of depressive symptoms and lower than expected rates of clinical depression in both groups may partially be due to methodological issues. As perinatal depression is a significant public health problem, more work is needed to prevent perinatal depression in low-income, ethnically diverse women.

Peak oxygen uptake of 12-18-year-old boys living in a densely populated urban environment

The prevalence of self-reported alcohol and marijuana use, along with alcohol abuse as measured by the Short Michigan Alcoholism Screening Test, was assessed for a community-based sample (n = 123) of persons with spinal cord injury (SCI). Correlates of alcohol and marijuana use and alcohol abuse also were examined, including demographic variables, measures of impairment, disability, and handicap, SCI medical complications, and measures of subjective assessment such as health rating, health maintenance behaviors, depression, life satisfaction, perceived stress, pain, and social support. Prevalence of alcohol use (59%) and marijuana use (16%) in persons with SCI was less than that of comparison groups in the general population. However, prevalence of alcohol abuse (21%) exceeded that of general population studies. Participants who abused alcohol shared the following criteria: (1) perceived their overall health as worse than those who did not abuse alcohol; (2) were more depressed; and (3) experienced more stress in their lives than those who did not abuse alcohol. Participants who used marijuana were younger at the time of the study and were younger at injury. They were also more depressed and more stressed. The indications of alcohol abuse in one in five persons with SCI living in the community mandates that screening, treatment, and referrals be part of any rehabilitation treatment program.     

Catastrophizing mediates associations between pain severity, psychological distress, and functional disability among persons with spinal cord injury.

Objective: To examine associations between pain severity, psychological distress, catastrophizing, and indices of functional disability in a sample of persons with spinal cord injury (SCI). Catastrophizing was examined as a potential mediator of associations between pain severity, psychological distress, and functional disability. Design and Participants: Questionnaires assessing pain severity, psychological distress, catastrophizing, pain interference, and community integration were completed by 237 persons with SCI. Results: Psychological distress and pain severity were associated significantly with greater functional disability. Moreover, the association between pain severity and functional disability was strongest among persons with high psychological distress. Catastrophizing appeared to mediate the associations between pain severity, psychological distress, and functional disability. Conclusions: Pain severity and psychological distress have the potential for both direct and interactive effects on functional disability, possibly through the mediating effects of catastrophizing.

Immunogenicity of pneumococcal vaccine in persons with spinal cord injury

OBJECTIVE: To determine immunogenicity and optimum timing for administering the 23-valent pneumococcal vaccine after spinal cord injury (SCI). DESIGN: Double-blind, randomized, placebo control study. SETTING: SCI unit in a tertiary care medical center and community. PARTICIPANTS: Eighty-seven persons with recent SCI. INTERVENTION: Participants were randomized to receive either placebo or pneumococcal vaccine at 16 to 18 days versus 4 to 6 months postinjury. MAIN OUTCOME MEASURES: Antibody concentrations were measured prior to intervention and 1, 2, and 12 months afterward to evaluate the immune response to five serotypes of Streptococcus pneumoniae. Effects of demographic and injury-related variables on immune response were also evaluated. RESULTS: Timing of vaccination did not influence mean antibody concentrations for any serotype (p > .05). Ninety-five percent of vaccinated persons had twofold or greater increases in antibody concentration for at least one serotype when measured 1 month after vaccination versus 35% of placebo groups (p < .01). After 12 months, 93% of vaccinated persons in both groups maintained antibody concentrations twofold or greater than baseline values. CONCLUSIONS: Most participants developed an immune response to at least one serotype that was maintained for at least 12 months. Immune response varied according to serotype. Given the favorable immune response and no effect of timing, persons with SCI should receive pneumococcal vaccine during initial hospitalization.     

Meta-analysis of cognitive-behavioral interventions on HIV-positive persons' mental health and immune functioning.

Objective: To evaluate the efficacy of cognitive-behavioral interventions (CBIs) for improving the mental health and immune functioning of people living with HIV (PLWH). Design: Comprehensive searches of electronic databases from 1988 to 2005, hand searches of journals, reference lists of articles, and contacts with researchers. Meta-analytic approaches were used in synthesizing findings. Main Outcome Measures: Intervention effects on symptoms of depression, anxiety, and anger, stress, and CD4 cell counts were assessed. Results: Data from 15 controlled trials were analyzed. Significant intervention effects were observed for improving symptoms of depression (d = 0.33), anxiety (d = 0.30), anger (d = 1.00), and stress (d = 0.43). There is limited evidence suggesting intervention effects on CD4 cell counts (d = 0.08). The aggregated effect size estimates for depression and anxiety were statistically significant in trials that provided stress management skills training and had more than 10 intervention sessions. Conclusion: CBIs are efficacious in improving various psychological states of PLWH. Future research should examine the relationship among interventions, psychological states, medication adherence, and immune functions, and identify other relevant factors associated with intervention effects.

Depression research methodologies in the Journal of Personality and Social Psychology: A review and critique.

Personality and social psychological studies of depression and depressive phenomena have become more methodologically sophisticated in recent years. In response to earlier problems in this literature, investigators have formulated sound suggestions for research designs. Studies of depression published in the Journal of Personality and Social Psychology (JPSP) between 1988 and 1993 were reviewed to evaluate how well these recommendations have been followed. Forty-one articles were examined for adherence to 3 suggestions appearing consistently in the literature: (a) multiple assessment periods, (b) multiple assessment methods, and (c) appropriate comparison groups. The studies published in JPSP have not adhered well to these standards. The authors recommend resetting minimum methodological criteria for studies of depression published in the premier journal in personality and social psychology.

Social-cognitive processes as moderators of a couple-focused group intervention for women with early stage breast cancer.

Objective: The purpose was to examine whether social-cognitive variables would moderate the efficacy of a couple-focused group intervention (CG) for women diagnosed with early stage breast cancer. Design: Participants (N = 238) were randomly assigned to 6 sessions of a couple-focused group versus usual care. Intent to treat growth curve modeling analyses indicated that emotional expression and emotional processing moderated CG effects on depression. Main Outcome Measures: The primary outcome measures for this study were psychological distress and psychological well-being. Results: Treatment attrition analyses separating out participants assigned to but not attending CG indicated that emotional expression, emotional processing, and protective buffering moderated the effects of CG among those who attended CG with the most consistent effects noted for emotional processing on indicators of distress and well-being. Conclusion: The CG intervention may be more effective for patients who begin the group experience using emotional approach coping strategies to deal with cancer.

Brief screening for psychological and substance abuse disorders in veterans with long-term spinal cord injury.

Objective: To determine rates of positive screens for psychological and substance use disorders in persons with long-term spinal cord injury (SCI). Study Design: A naturalistic cohort design wherein consecutive admissions during an 8-month period completed the screening battery. Setting: Veterans Affairs SCI Center. Participants: One hundred fifteen men, 2 women, mean age 57.4 years, injured an average of 20 years, readmitted for various reasons. Main Outcome Measures: The Alcohol Use Disorders Identification Test (AUDIT) and screening items for depression and anxiety disorders. Results: Rates of positive screens ranged from 6.2% for alcohol problems to over 40% for anxiety disorders. Positive screens for depression and anxiety correlated positively with the number of recent hospital admissions. Conclusions: Systematic brief screening for psychological and substance abuse disorders in this population revealed rates of positive screens at least equal to those in other medical patient populations.
