Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans (open access)

Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans

The purpose of this study was to determine relationships between acculturation level, generational status, and gender with acculturative stress. Acculturation level was determined by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) and acculturative stress was determined by the Societal, Attitudinal, Familial and Environmental Acculturative Stress Scale-Children's Version (SAFE-C). Subjects included 1268 Hispanic children ages 11-15. In order to validate the usefulness of the ARSMA-II with this sample, analyses were conducted between acculturation level and generational status. The Pearson product moment correlation (r=.44) and the ANOVA between the mean acculturation score and generational status were significant. However, the mean acculturation score from this study was considerably lower than the ARSMA-II score; therefore, new acculturation levels were developed to establish local adolescent norms for the ARSMA-II. All analyses involving acculturation levels were conducted using both the ARSMA-II and new acculturation levels because 300 subjects were reclassified with the new norms. Significant results were similar using both acculturation levels; however, there were more between group differences using the new acculturation levels. It was hypothesized that as acculturation level increased toward the Anglo culture, acculturative stress would decrease. The one-way ANOVA confirmed this relationship. It was also hypothesized that as generational status increased, …

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing (open access)

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing

This study explores the possibility that attentional deficits are an early clinical symptom of Alzheimer's disease. The three goals are to demonstrate that individuals with Alzheimer's disease are impaired on tasks of attentional processing, to compare the sensitivity of currently used measures of attention to attentional dysfunction, and to compare the behavioral response styles (errors of commission) of Alzheimer's disease subjects and non-impaired subjects. The subjects were 22 males and 46 females with a mean age of 70.76 years. Thirty-six had the presumptive diagnosis of Alzheimer's disease; 18 were identified as mildly impaired and 18 as moderately impaired on the Cognitive Capacity Screening Examination. The remaining 32 subjects comprised the non-impaired control group. Five measures of attention were administered to all participants: the Digit Span Subtest of the WAIS-R, the Seashore Rhythm Test of the Halstead-Reitan Neuropsychological Battery, the Vigilance and Distractibility tasks of the Gordon Diagnostic System, and the Concentration/Interference task. The results show a significant difference in attentional processing between normal (non-impaired) subjects and subjects diagnosed with Alzheimer's disease. All measures of attention used in this study, except the Concentration/Interference task, differentiated normal subjects from moderately impaired Alzheimer's disease subjects. The Digit Span Subtest and the Seashore Rhythm …

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy (open access)

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but …

Association Between Folate, Vitamin B12 and Cognitive Performance in Demented Elderly. (open access)

Association Between Folate, Vitamin B12 and Cognitive Performance in Demented Elderly.

Dementia is prevalent among elderly people. As the world population ages, it is projected that the number of people affected by dementia may triple in the next 50 years. Over the last two decades, research has focused on identifying potentially modifiable risk factors in development and progression of dementia, such as vitamin B12 and folate. Results concerning the effects of low folate and vitamin B12 on cognitive performance are mixed. The main objective of the present study was to investigate the effects of vitamin deficiency on cognitive functioning in a clinical sample of elderly individuals with cognitive problems using a comprehensive neuropsychological assessment. A retrospective chart-review was performed on the 102 records of patients from the Geriatrics Clinic at the University of North Texas Health Science Center who presented with cognitive deficits. Charts were reviewed to obtain data on vitamin supplementation, vitamin status, history of chronic conditions and other biochemical data. The available database was used to obtain data on neuropsychological assessment. The study demonstrated mild association between vitamin B12 and folate status and cognitive deficits. There appeared to be a higher cut-off level that is above the traditionally used levels for vitamin B12 and folate deficiency concentrations at which …

Autonomic Balance and Control of Stress for Participants Identified as High or Low Hostile and as Having a Positive or No Family History of Cardiovascular Disease (open access)

Autonomic Balance and Control of Stress for Participants Identified as High or Low Hostile and as Having a Positive or No Family History of Cardiovascular Disease

The influence of autonomic activation in response to controllable versus noncontrollable stress, anger imagery induction, and relaxation imagery was studied among 80 participants between the ages of 18 and 34. Participants differed in level of trait hostility as assessed by the Irritability Subscale of The Buss-Durkee Hostility Inventory (Buss & Durkee,1957) and the Ho scale of the Cook-Medley Hostility Inventory (Cook & Medley, 1954). Groups were further subdivided with regards to either having a positive family history of cardiovascular disease or having no significant history. Results were obtained through analyses of electrocardiograph R-R intervals which produced an index of autonomic nervous system activation. Findings supported hypotheses involving the relations between autonomic balance and stress and hostility for the female and male populations. Among both populations, parasympathetic regulation was diminished during anger induction for individuals with high levels of trait hostility and having a family history of cardiovascular disease. Similar results were obtained for men during relaxation imagery induction.

Behavior Patterns among Children with a History of Metopic Synostosis (open access)

Behavior Patterns among Children with a History of Metopic Synostosis

Metopic synostosis is a condition in which the metopic suture of the human cranium fuses prematurely and may be related to poor behavioral inhibition leading to behaviors commonly associated with Attention-Deficit Hyperactivity Disorder (ADHD). The purpose of this project was to examine the behavior patterns among children with a history of metopic synostosis. It was hypothesized that children with a history of metopic synostosis would exhibit many of the same behavioral patterns associated with ADHD. It was also hypothesized that children with a history of simple synostosis not involving the metopic suture would not evidence this type of behavioral pattern. In order to test these hypotheses, the behavior of three groups of children was compared including (1) children who had a history of metopic synostosis (M= 7.63 years, SD = 1.92 years), (2) children who had a history of simple craniosynostosis not involving the metopic suture (M= 7.54 years, SD = 1.88 years), and (3) a group of children diagnosed with ADHD (M=7.78 year, SD = 1.87 years). It was found using the Home and School versions of the Attention Deficit Disorders Evaluation Scale (ADDES) that children with a history of metopic synostosis demonstrate significantly more behavioral disturbances than children …

Cardiovascular Problems as a Predictor of Later Cognitive Decline: Moderating Effect of General and Spousal Social Support. (open access)

Cardiovascular Problems as a Predictor of Later Cognitive Decline: Moderating Effect of General and Spousal Social Support.

Individuals are living longer now than they have in the past. As a result, there is an increased incidence in illnesses that are more prevalent in later life. One group of illnesses that is more prevalent is age related dementia. Alzheimer's disease (AD) and vascular dementia (VaD) are two common types of dementia found in the older adult population. Recent research suggests that these two types of dementia may both have a vascular component that is instrumental in their development. Not only may this vascular component be present in both these illnesses, but also it may be related to a more severe cognitive decline in the aging process. Results indicate that both cardiovascular disease and general and spousal social support in middle age are all three independent significant predictors of mild cognitive impairment and other non-normative cognitive impairment in later life. However, results do not indicate that social support moderates the relationship between cardiovascular disease and cognition.

Changes in Quantitative EEG and Low Resolution Tomography Following Cranial Electrotherapy Stimulation.

The effects of cranial electrotherapy stimulation (CES) on human EEG and brain current density were evaluated by quantitative electroencephalography (qEEG) and low resolution brain electromagnetic tomography (LORETA). A total of 72 research subjects were provided with a single session of CES, 38 were provided with 0.5 Hz CES while 34 were provided with 100 Hz CES. The qEEG paired t-tests revealed that in both frequencies of CES there was a significant (.05) increase in alpha relative power with concomitant decreases in delta and beta relative power. The 0.5 Hz CES decreased a wider frequency range of delta activity, while the 100 Hz CES decreased a wider frequency range of beta activity; suggesting some difference may exist in the EEG response to different frequencies of CES. The changes found in qEEG relative power were consistent with the affective and cognitive effects of CES reported in the literature, such as increased relaxation and decreased anxiety. Statistically significant changes for qEEG values other than relative power, such as coherence, amplitude asymmetry, phase lag and power ratios were also found. The LORETA paired t-tests found statistically significant (.05) increases in cortical and subcortical theta and alpha frequency current density with concomitant decreases in delta …

The objective of the present study was to investigate Amen's formulations of subtypes of AD/HD initially identified by brain imaging techniques, through the use of behavioral checklist data. And in testing Amen's theory of six separate subtypes of AD/HD, to identify and differentiate the subtypes based on symptom presentation. Data was obtained through retrospective chart reviews (N=161) of children between the ages of 5 and 12 who met the criteria for the major symptoms observed in AD/HD and were referred for a previous comprehensive AD/HD evaluation. Data from behavioral checklist (CBCL and DBRS-IV) were matched to Amen's Subtype Symptom Checklist and each subject was given a percentage score for six subtype symptoms. Cluster analysis reliably found six clusters and each subject was labeled according to their symptom presentation. The clusters found were labeled as AD/HD - Combined Type, AD/HD - Predominately Inattentive Type, AD/HD - Predominately Hyperactive-Impulsive Type, Ad/HD - Combined Type with Obsessive-Compulsive features, AD/HD - Combined Type with Obsessive/Compulsive and Conduct Disorder features and Undifferentiated AD/HD. However, the present study did not find evidence of subtypes that corresponded to Amen's Temporal Lobe ADD or Limbic ADD.

Cognitive Differences Between Congenitally and Adventitiously Blind Individuals. (open access)

Cognitive Differences Between Congenitally and Adventitiously Blind Individuals.

It is apparent from the historical perspective regarding the theories of cognitive development and the cognitive functioning of individuals with visual impairments, that sight plays a major role in the development of certain cognitive processes. However, the affects of visual impairment on cognitive development remain to be at issue. Since sight seems to be highly integral in cognitive development beginning in the early stages of physical development, about the sixth month of life, and then begins to diminish in importance as verbal communication develops around eighteen months, then it should stand to reason that significant visual impairment or blindness occurring prior to this time would adversely impact an individual's cognitive development. Conversely, the occurrence of visual impairment or blindness after this critical period of development would have less of an impact. Cognitive theorists have proposed that visually impaired or blind persons may have developed different cognitive pathways to acquire, process, and accommodate sensory information. As a result, visually impaired or blind (VI/B) persons may "think differently" than sighted individuals. The present study was designed to address these issues as they relate to cognitive and neuropsychological development at various stages of growth and to examine possible differences in neuropsychological functioning dependent …

Cognitive Dysfunction in Middle-Aged Adults vs. Older Adults with Obstructive Sleep Apnea (open access)

Cognitive Dysfunction in Middle-Aged Adults vs. Older Adults with Obstructive Sleep Apnea

The presence of cognitive deficits in obstructive sleep apnea (OSA) is well-documented. Specifically, short- and long-term memory, attention/vigilance, and executive function (e.g. processing speed, mental flexibility, and problem solving) are affected. Cognitive deficits in aging occur in similar areas (i.e., memory and processing speed). Given that a greater percentage of older adults experience sleep-disordered breathing as compared to middle-aged adults, it is possible that OSA may account for some of the deficits typically attributed to aging. This study investigated this hypothesis by comparing middle-aged and older adults with and without OSA on computer-based measures of cognitive performance. No effect of OSA or an interaction between OSA and age on cognitive function was found; an effect of age on processing speed, distinguishing stimuli rapidly, attention, spatial ability/mental flexibility, and both working memory and short-term visual memory was found. This study also explored whether or not cognitive function may be improved in persons with OSA by re-assessing those participants one month after treatment. An effect of treatment on improvements on processing speed, distinguishing stimuli rapidly, mental flexibility, and short term memory was found. Overall, findings reflect the ability of treatment to improve cognitive function among OSA patients, regardless of lack of deficits …

A Comparison of Imagery Relaxation and an Educational Treatment Modality for Dysmenorrhea (open access)

A Comparison of Imagery Relaxation and an Educational Treatment Modality for Dysmenorrhea

This study is a comparison of four treatments involving education and imagery relaxation for the amelioration of dysmenorrhea. Treatment was presented to 76 subjects by videotape during a one-hour session. A six month follow-up was performed using one of the original instruments, the Symptom Severity Scale (Cox & Meyer, 1978) and a questionnaire designed for the study. Analysis of the test instruments indicated a significant treatment effect for the educational group. The second most effective treatment was a combined treatment utilizing imagery relaxation and education, although this group did not produce significant results. The no-treatment control group was more effective in diminishing symptoms than the fourth group, imagery relaxation alone. The lack of effectiveness of the imagery relaxation treatment was hypothesized to be due to lack of reinforcement of the technique. The educational treatment modality offered the individual an opportunity to learn about many different etiological facets of dysmenorrhea, including biological, learning, and cognitive factors. The presentation also introduced the individual to several different treatment modalities in order to provide an armamentarium of effective methods for diminishing or eliminating dysmenorrhea. These results suggest that there is a need for education about dysmenorrhea before menarche, in order to prepare, prevent, treat, …

Development and Psychometric Validation of the State-Trait Spirituality Inventory (open access)

Development and Psychometric Validation of the State-Trait Spirituality Inventory

The present study contributes to the widening body of spirituality research by conceptualizing it as a state-trait construct. A new measure of spirituality, the State-Trait Spirituality Inventory (STSI), was created and validated according to psychometric methods of test construction. In its current form, the STSI contains seven state spirituality items and six trait spirituality items. A thorough review of the literature identified common themes in spirituality definitions and assisted in developing definitions of trait and state spirituality. Internal consistency for the trait scale was .88 and for the state scale, .68. Good test-retest reliability was found with coefficients of .84 for trait spirituality and .81 for state spirituality. Results from a preliminary undergraduate sample as well as from the validation sample yielded a two-factor solution. In general, items determined by expert panels as trait items loaded on one factor and items deemed to be state items loaded on the second factor. Multitrait multimethod analysis yielded mixed findings for convergent, divergent, and concurrent validity for the spirituality and religiosity traits. Methods consisted of paper-and-pencil cognitive and behavioral measures. Cognitive measures were more likely to support convergent/divergent validity than were behavioral measures. A major emphasis in the study was to determine whether …

Development of a Differential Neurocognitive Profile for Alzheimer’s Dementia and Vascular Dementia (open access)

Development of a Differential Neurocognitive Profile for Alzheimer’s Dementia and Vascular Dementia

Alzheimer’s Dementia (AD) is among the most common diseases in the Geriatric population, and its prevalence is expected to quadruple by 2047.Vascular Dementia (VaD) is the second most frequent cause of dementia, with studies indicating VaD accounts for 10-20% of dementia cases across the globe. A diagnostic model differentiating AD and VaD would be clinically and scientifically valuable, considering the treatment approaches for these conditions are different. Although there are differences between AD and VaD on their neuropsychological profiles, a diagnostic model that successfully differentiates AD and VaD on neuropsychological testing has not been developed, despite previous attempts. Our study addresses this gap in the literature by examining two diagnostic models used to predict the conversion of AD from mild cognitive impairment, and a third model was proposed to differentiate AD from VaD. We conducted ROC Analyses using the variables LM II Standard Score, Animals Total, and CDRS Sum based on a previous diagnostic model. The sensitivity and specificity for the diagnosis of mild VaD were calculated for all possible scores of each test measure. The Animals Total cutoff score of 7 achieved excellent sensitivity and specificity, receiving 96% and 92%, respectively. In this sample, patients who could name at …

Does Unemployment Become a Major Stressor in the Evolution of Chronic Pain?

Pain has been described as the most complex human experience and most frequent reason patients seek medical treatment. Few people fail to experience the pain associated with disease, injury, or medical/surgical procedures. However, the impact of unemployment that results from chronic pain suffering has not been widely researched. To present a comprehensive view of the effect unemployment has upon the chronic pain experience, this study focused upon stress philosophy, chronic pain, employment, and coping effectiveness. The Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and a Personal Data Questionnaire (PDQ) were administered to 96 persons (four groups of 24 subjects) representing either unemployed or employed and either chronic or non-chronic (acute) pain populations.

The Effect of a Brief Acceptance-Based Protocol on Health Related Relational Framing (open access)

The Effect of a Brief Acceptance-Based Protocol on Health Related Relational Framing

Behavior analysts who study verbal behavior theorize that people derive relationships between stimuli - forming stimulus classes such that psychological functions transfer among stimuli and therefore affect behavior. Verbal processes are thought to play a role in cancer patients' behavioral flexibility. The current study examined if an analogue intervention produced changes in relations between health-relevant stimuli from pre- to post-test in patient and student samples. A matching-to-sample (MTS) task required participants to form three 4-member classes that included health, treatment, or neutral terms. Participants next listened to either an acceptance-based or a control-based rationale and therapy exercise, or a distracter task. Then, they were re-exposed to the MTS task. Latencies and accuracies for learning each class as well as between condition differences were examined. Finally, changes in ratings of stimuli from pre to post analogues were measured. Differences in stimuli ratings were seen in the student sample, reflecting transfer of function and some reduction in responsiveness to stimuli following intervention, but overall no learning performances are found. Discussion explores the consistency of the findings with acceptance and commitment therapy (ACT) theory in light of the seemingly lack of findings.

The Effectiveness of the Geriatric Depression Scale to Distinguish Apathy From Depression in Alzheimer's Disease and Related Dementias. (open access)

The Effectiveness of the Geriatric Depression Scale to Distinguish Apathy From Depression in Alzheimer's Disease and Related Dementias.

Early detection of Alzheimer's disease (AD) and related dementias in the elderly is critical for improving treatment methods and is a necessary component for improving public health interventions. One of the earliest and most common behavioral syndromes of AD is apathy and is associated with executive dysfunction. Apathy in AD is often misdiagnosed as depression due to an overlap in symptoms. Studies that have found depression to be associated with executive dysfunction have not always controlled for the presence of apathy. The Geriatric Depression Scale (GDS) is a widely used instrument designed to assess depression in the elderly. This study utilized the GDS and a set of standard neuropsychological instruments to investigate the relationship between apathy, depression, and executive functions in individuals with AD and related dementias. The first objective of this study was to determine if apathy has a greater impact on executive functions compared to depression in AD and related dementias. The second objective was to determine the effectiveness of the GDS as a screen for apathy. The results of the analyses did not support the hypotheses. However, exploratory analyses suggested a possible non-linear relationship with apathy and various levels of dementia severity. Exploratory analysis also suggested mean …

The Effects of Positive Emotion, Negative Emotion, Flourishing, and Languishing on Cardiovascular Risk

Positive psychology has led a movement that concentrates on positive characteristics. The current study examined the relationship between positive emotions, negative emotions, flourishing, languishing, and cardiovascular functioning. The study uses guided imagery to help participants recall a negative emotional event and positive emotional event in a counterbalanced order. The reverse order allowed us to examine the differential contributions of stress buffering versus facilitated recovery effects to higher levels of heart rate variability (HRV). The study also examined the relationship between mental health categories and known cardiovascular disease risk. Univariate analysis of variance revealed that positive emotions can serve as a stress buffer and dampen cardiovascular responses to a negative event. Also, analysis revealed a trend for the prediction that positive emotions can facilitate cardiovascular recovery following a negative event. Exploratory analysis did not reveal differences between a facilitated recovery group and a buffering group for cardiovascular measures. Future studies should include tighter control to help compare the differential influences of stress facilitation and stress buffering on cardiovascular functioning. The results from the study indicate that it is still too early to tell whether mental health buffers those individuals from developing CVD, and to answer whether languishing increases the risk of …

Efficacy of neurofeedback for children with histories of abuse and neglect: Pilot study and meta-analytic comparison to other treatments.

This two-part study investigates the effectiveness of neurofeedback training for reducing behavioral problems commonly observed in abused/neglected children, and compares its efficacy to other treatment interventions with this population. Neuro-developmental sequelae of early relationship trauma are explored as an etiological framework for understanding disturbed affect-regulation, which appears central to the behavioral and emotional difficulties commonly experienced by this pediatric population. It is suggested that neurofeedback teaches children to self-regulate brain rhythmicity mechanisms, which in turn affects global improvements in behavior and mood. The pilot study utilizes records of 20 children removed from their biological homes by Child Protective Services. Children were assessed prior to treatment using the Child Behavior Checklist (CBCL) and the Test of Variables of Attention (TOVA), and again after 30 sessions of individualized, qEEG-guided neurofeedback training. A t-test analysis of pre- and post-scores was computed, and indicated significant improvements following treatment. A meta-analysis of existing literature on treatment interventions with abused/neglected children provides individual and aggregate effect sizes for 33 outcome studies with this clinical population, and contextualizes the results of the present pilot study within other empirically validated treatment modalities.

Evaluating the Role of C-reactive Protein on Cognition and Depressive Symptoms Among Women by Mexican American Ethnicity (open access)

Evaluating the Role of C-reactive Protein on Cognition and Depressive Symptoms Among Women by Mexican American Ethnicity

C-reactive protein (CRP) is a protein found in the blood that is synthesized by the liver and has been extensively studied due to its role in inflammatory and atherosclerotic processes. The importance of this biomarker in its role in vascular risk factors is increased with several lines of evidence pointing to its association with cognitive decline. The association between CRP and depression has been increasingly analyzed by various cross-sectional studies. The research between CRP and depressive symptoms in older women has yet to generate consistent trends. In the present study, a series of regression analyses was used to explore the association between CRP and both cognitive function and depressive symptomatology among a group of rural-dwelling women. Associations were evaluated through the use of data from Project FRONTIER, a rural-based research looking at both physical and cognitive aspects of health in rural-dwelling adults and elders. Comparisons were made between Mexican American women and a group of non-Hispanic Caucasian women. CRP was a significant independent predictor of total depression (beta = -.11, t = -1.99, p =.048). CRP was also a significant independent predictor of symptoms associated with meaningless within depression (beta = -.16, t = -2.94, p =.004). Contrary to prediction, …

Evaluation of skill maintenance, performance factors, and external validity in a behavioral parent training program. (open access)

Evaluation of skill maintenance, performance factors, and external validity in a behavioral parent training program.

Child maltreatment affects 900 thousand children in the U.S. every year and impacts all areas of daily functioning. Behavioral parent training (BPT) programs have effectively taught parenting and demonstrated externally valid outcomes (i.e., lower recidivism rates). Skill maintenance assessments for BPTs have mixed results. The Behavior Management and Parenting Services (BMAPS) program has shown effective skill training for court-mandated families. This study assessed skill maintenance and performance factors that may have impaired parents using an ABAB single-case research design in Phase 1 & external validity with a survey in Phase 2. Results for Phase 1 found that most BMAPS parents acquired all parenting tools to criteria, dropped below criteria at the 3 month probe, then fully demonstrated their regained skills after a brief review. Psychological and classroom factors do not appear to have systematically influenced performance at any time, although homework completion was associated with better scores at the end of class. Phase 2 results found a 91% reunification rate and a 0% recidivism rate over 1-3 years. All limitations aside, it appears that the BMAPS program is able to effectively train skills to criteria and these skills can be sustained with a booster session. The vast majority of parents …

Evaluation of the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) in a spinal cord injury population.

Spinal cord injury (SCI) is an acute and devastating event that results in significant and permanent life changes for the individuals who are injured, as well as their families and friends. Depression has received more attention from clinicians and researchers than any other psychological issue among persons with SCI. Measurement of depression in this population has a variety of methodological issues, including inconsistent assessments used (self-report versus clinical interviews), varying definitions of depression, inclusion and exclusion of physical symptoms in the assessment process, and use of measures that do not represent DSM-IV criteria for major depressive disorder. The primary goal of this study was to evaluate the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) and provide descriptive analyses of this measure with persons with SCI. Results showed that somatic symptoms were more frequently endorsed than psychological symptoms in this population. Additionally, scores on the QIDS-SR were significantly associated with a depression diagnosis in the patient's medical chart. However, QIDS-SR scores were not found to be correlated inversely with quality of life scores as predicted. The QIDS-SR was shown to have good internal consistency and convergent validity with patients with SCI. However, it failed to demonstrate construct validity. The QIDS-SR …
