RESUMO
Recent studies have reported a high prevalence of symptoms of post-traumatic stress disorder (PTSD) among individuals with chronic pain. Studies suggest that persons with pain and PTSD also display higher levels of affective disturbance. In the present study we examined self-reports of pain, affective disturbance, and disability among pain patients with and without symptoms of PTSD. Patients without PTSD symptoms were further subdivided into persons whose pain was the result of an accident or insidious in onset. Thus, three groups were examined: (1) persons with accident related pain and high PTSD symptoms (Accident/High PTSD); (2) persons with no or few symptoms of PTSD whose pain was accident related (Accident/Low PTSD); and (3) patients whose pain was not accident related and did not have PTSD symptoms (No Accident). No Accident patients were older than persons with accident related injuries, and both accident related pain groups were more likely than No Accident patients to be involved in litigation or receiving compensation. Thus, these variables were controlled for in the statistical analyses. Self-report of pain was also included as a covariate in the analyses examining group differences in affective disturbance and disability. Accident/High PTSD patients displayed higher levels of self-reported pain compared to the other two groups. The Accident/High PTSD group also had the highest levels of affective disturbance. Both accident groups tended to report greater disability compared to patients whose pain was not accident related. These findings suggest that PTSD symptoms in chronic pain patients are associated with increased pain and affective distress. Accident related pain, even without the presence of PTSD symptoms, appears to be associated with greater disability. The results indicate that the identification and treatment of PTSD symptoms in refractory pain patients may be a critical albeit subtle factor in the effective management of suffering and disability in this population.

Yohimbine has had questionable effects in men with organic erectile dysfunction. We conducted this study to better define the population of men responsive to yohimbine, because tobacco was thought to affect a regimen of yohimbine more than other risk factors. We measured nocturnal penile tumescence with the RigiScan monitor, hormone profiles, answers to the Florida Sexual Health Questionnaire, and clinical responses at baseline and after two different doses of yohimbine in 18 nonsmoking men with erectile dysfunction. Of the 18 men, nine (50%) were successful in completing intercourse in more than 75% of attempts. The yohimbine responders were men with less severe erectile dysfunction as manifested by improved increased rigidity on RigiScan testing, higher Florida Sexual Health Questionnaire scores, and slightly higher levels of serum testosterone. Yohimbine is an effective therapy to treat organic erectile dysfunction in some men with erectile dysfunction.

A recent study demonstrated the Florida Sexual History Questionnaire (FSHQ) is reliable and valid when used to discriminate impotent from nonimpotent men. This study examined the ability of the FSHQ to discriminate between men with primary psychogenic and primary organic impotence in a sample of impotent diabetics and a larger group of impotent men. The hit rate in the diabetic sample was 81% using an eight-item discriminant function, and 70% using the total score. Hit rates in the larger sample were significant but lower (73% and 66%). The results suggest that the FSHQ has concurrent validity in terms of discriminating primary organic from primary psychogenic impotence.

The purposes of the present study of chronic pain patients were to (a) assess whether cognitive and behavioral coping style is related to personality factors, (b) assess how coping styles differ across personality types, and (c) assess how outpatient interdisciplinary intervention affects the coping styles of various personality types. Four MMPI clusters (Depression/Pathological, V-type, Marginal Depression, and Marginal V-type) were derived using a hierarchical clustering procedure. Seventy subjects also completed the Coping Strategies Questionnaire before and after a 3-week outpatient pain management program. Pretreatment analyses indicated the Depression/Pathological and Marginal Depression groups used diverting attention less than either V-type group. The V-type group reported using praying/hoping significantly more than either of the marginal groups. At posttreatment the Depression/Pathological group used catastrophizing significantly more than either of the marginal groups. Results of pre-post analyses indicated that the Depression/Pathological group increased their use of diverting attention, reinterpreting pain sensations, and ignoring pain sensations, while decreasing catastrophizing. The V-type group increased their use of reinterpreting pain sensations, while decreasing praying/hoping and catastrophizing. Neither of the Marginal subtypes showed significant pre-post changes in coping strategies. These results suggest that different personality types use different pain coping strategies prior to multidisciplinary treatment. Groups showing more severe psychological distress, perhaps related to an underlying personality disorder, displayed greater changes in coping strategies with treatment, but remained more dysfunctional after treatment. These findings suggest that the alteration of coping strategies may be an important treatment effect needing more individualization to maximize treatment response.(ABSTRACT TRUNCATED AT 250 WORDS)

OBJECTIVE: This study attempts to clarify the relationship between depression and the cognitions of chronic pain patients. It was hypothesized that the ambiguity and desirability of self-rated traits would significantly predict level of depression. DESIGN: The study incorporated a correlational design in which subjects rated a number of traits as they pertained to themselves and completed questionnaires on negative affect and pain. SETTING: Subjects were recruited from a Spine Program and the Orthopaedic Clinic, at a tertiary care facility at the University of Florida. SUBJECTS: Fifty-eight chronic pain patients, two thirds of whom had primary back pain, were recruited for the study. OUTCOME MEASURE(S): All subjects completed a Beck Depression Inventory and McGill Pain Questionnaire, and rated themselves on 28 traits characterized by the dimensions of desirability and ambiguity. RESULTS: A hierarchical regression analysis indicated that the subjects' self-ratings on ambiguous negative traits significantly predicted level of depression. CONCLUSIONS: Patients with chronic pain are more likely to acknowledge undesirable traits in themselves when they have higher levels of depression when the pain level was controlled. These findings may have important implications for the cognitive-behavioral treatment of chronic pain patients.

OBJECTIVE: This study examined the ability of two self-report questionnaires, the Beck Depression Inventory (BDI) and the Center for Epidemiological Studies-Depression Scale (CES-D), to discriminate between chronic pain patients with and without major depression. Since previous research has suggested that medical conditions such as chronic pain can influence the endorsement of items that measure neurovegetative symptoms of depression, the accuracy of each of these questionnaires was also assessed eliminating these items. SUBJECTS: These included 132 consecutive patients with chronic pain, 44 of whom were diagnosed as suffering from major depression according to DSM-IV criteria. METHODS: Patients were administered a battery of questionnaires that included the CES-D and BDI. They were also interviewed by a clinical psychologist to determine the presence or absence of major depression. RESULTS: Both questionnaires were able to discriminate significantly between persons with and without major depression. Removal of the somatic items on each questionnaire did not improve their accuracy. Discriminant function analysis revealed an optimal cut-off score of 21 for the BDI, and 27 for the CES-D. Overall hit rates at these cut-offs for the two questionnaires were comparable, while the CES-D had somewhat better sensitivity (81.8% vs. 68.2%). Conversely, the BDI had slightly better specificity (78.4% vs. 72.7%). CONCLUSION: The results suggest that both questionnaires have good predictive validity among chronic pain patients, and decisions regarding the use of one questionnaire rather than the other may depend upon the goals of the user and the setting within which the questionnaire is used.

OBJECTIVE: Some studies have found significant relations between both the factor scores and subscales of the Coping Strategies Questionnaire (CSQ) and various measures of adjustment to chronic pain. In their review of the literature on coping with chronic pain, Jensen et al. (Pain 1991;47:249-83) suggest that conceptual overlap between the subscales may inflate these observed correlations. In the present study, we examine the factor structure of the CSQ subscales which reflect coping, excluding the CSQ subscales which measure appraisal or activity. We then examine the relationship between the CSQ factors and subscales and pain adjustment, while controlling for selected variables. DESIGN AND SUBJECTS: One hundred fifty-two chronic pain patients were administered the CSQ. Seventy-three were also administered the Multidimensional Pain Inventory (MPI). Adjustment to chronic pain was defined based on patients' cluster membership on the MPI and responses to the Interference, Pain Severity, and Negative Affect subscales. SETTING: Tertiary care center. RESULTS: Multiple regression analyses revealed that the Pain Avoidance factor was positively related to pain severity, interference, and MPI cluster membership. In addition, the catastrophizing subscale was positively related to negative affect and MPI cluster membership even when controlling for level of depression, ability to decrease pain was related to lower levels of pain severity, and ability to control pain was related to MPI cluster membership. Neither the Conscious Cognitive Coping factor nor the Increasing Activities subscale was related to the adjustment measures. Follow-up analyses revealed that the Praying/Hoping subscale appeared to account for the relationship between pain avoidance and adjustment. CONCLUSION: The results suggest that praying/hoping and catastrophizing are related to poorer adjustment to chronic pain, that ability to control and decrease pain are related to better adjustment, and that catastrophizing appears to be a separate construct from depression. The results also suggest that the individual CSQ subscales may have greater utility in terms of examining coping, appraisals, and pain adjustment compared to the composite scores.

OBJECTIVE: The purpose of this study was to examine the dimensions of coping, measured by the subscales of the new revised Coping Strategies Questionnaire (CSQ-R) using factor analysis, and to perform cluster analysis on these factors to explore the existence of distinct subgroups. No published studies have identifed subgroups of chronic pain patients based on the use of CSQ coping strategies. SOURCE: A sample of 419 chronic low back pain patients from a multidisciplinary pain rehabilitation clinic and a sample of 556 chronic pain patients of mixed pain etiology presenting for treatment at an anesthesia pain clinic were used to establish reliability of factors and clusters. RESULTS: Both samples yielded very similar two-factor solutions, with initial solutions accounting for 67.1% and 69.1% of the total variance. The factors were characterized as cognitive coping and distraction. Three homogeneous subgroups were then identified that consisted of a group high on cognitive coping, a group with low overall ratings of response CSQ-R items in general, and a group with frequent endorsement of catastrophizing and distraction-related items. CONCLUSION: This paper is the first to report empirically derived subgroups from scores on the CSQ or CSQ-R. In addition, the three clusters were significantly different across measures of pain, psychological distress, and levels of physical functioning, demonstrating validity for the clusters.

OBJECTIVE: The goal of this study was to examine the relative importance of global affective distress, self-report of depressive symptoms, and presence or absence of major depression to the experience of chronic pain. SETTING: A multidisciplinary pain program at a university medical center was the setting for this study. PATIENTS: Subjects in this study were 211 consecutive patients with chronic pain. OUTCOME MEASURES: Pain duration, compensation, and litigation status were controlled for in the statistical analyses, as each correlated significantly with at least one of the measures of affect. Global affective distress was assessed using the Global Severity Index (GSI) from the Brief Symptom Inventory. The Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale were used as measures of self-report of depressive symptoms. Presence or absence of major depression was based on DSM-IV criteria. RESULTS AND CONCLUSIONS: The GSI, Beck Depression Inventory, and Center for Epidemiological Studies Depression Scale were significantly correlated with each measure of the experience of pain, although clinical depression was only significantly related to self-reported disability and negative thoughts about pain. The self-report measures of depression maintained their relation to the dependent measures when the somatic items from the scales were removed, suggesting that the relations were not spuriously due to the influence of pain symptoms on the scales. When examining the unique contribution of each variable to the experience of pain (by simultaneously controlling for the other measures of affect), the GSI was uniquely related to the sensory and affective components of pain. Self-report of depressive symptoms was more highly related to a measure of the evaluative component of pain and uniquely related to self-reported disability and negative thoughts about pain. The results are discussed within the context of theoretical models of the relation between pain and affect, and suggestions for future research are presented.

OBJECTIVE: The present study employed causal modeling to examine the impact of somatic and cognitive symptoms of depression on the functioning of patients with chronic pain. DESIGN: Path analyses were conducted to determine whether pain level is directly related to the psychosocial and physical dimensions of functional status or whether this relationship is mediated by depression. SETTING: Subjects were recruited from a facial pain clinic at the University of Florida, an outpatient clinic associated with a tertiary-care health center. PATIENTS: Subjects were 70 patients with chronic pain, 53 of whom had primary facial pain. MAIN OUTCOME MEASURES: All subjects completed a packet of self-report questionnaires, including the Beck Depression Inventory, McGill Pain Questionnaire, and Sickness Impact Profile. RESULTS: Results of path analyses indicated that both somatic and cognitive symptoms of depression significantly correlate with psychosocial functioning even after controlling for the effects of pain level, trait anxiety, and trait anger. Somatic symptoms of depression were significantly correlated with physical functioning after pain level, anxiety and anger were controlled. CONCLUSIONS: This study indicates that depression is directly related to both the physical and the psychosocial functioning of facial pain patients, while self-reported level of pain is not. A better understanding of the impact of depression on chronic pain and the relationship of these two disorders could lead to improved assessment and treatment of chronic pain disorders.

OBJECTIVE: The purpose of our study was to investigate whether Minnesota Multiphasic Personality Inventory-2 cluster solutions of chronic low-back pain patients would replicate those found in previous research with the Minnesota Multiphasic Personality Inventory. SETTING: A multidisciplinary pain clinic in the southeastern United States. PATIENTS: The subjects were 201 chronic low-back pain patients who had suffered a work-related back injury. OUTCOME MEASURES: The Minnesota Multiphasic Personality Inventory-2. RESULTS: We found four relatively homogeneous subgroups of chronic low-back pain patients that were similar to those identified by previous researchers using data collected with the Minnesota Multiphasic Personality Inventory. CONCLUSION: These findings indicate that interpretations of the Minnesota Multiphasic Personality Inventory-2 should parallel those of the Minnesota Multiphasic Personality Inventory for chronic low-back pain patients. They further suggest that the results of Minnesota Multiphasic Personality Inventory-based studies are also applicable to Minnesota Multiphasic Personality Inventory-2.

OBJECTIVE: Although the West Haven-Yale Multidimensional Pain Inventory (MPI) is frequently used in clinical evaluation and research with chronic pain patients, few studies have reported item-level factor analyses. After performing such an analysis, Bernstein et al. (Spine 1995;20:956-63) reported lack of independence between the solicitous and distracting response scales in section II as well as the activities away from home and social activities scales in section III. They suggested that the combination of these scales would improve the internal structure of the MPI. The purpose of this study was to perform a confirmatory factor analysis testing whether the MPI would be improved by the consolidation of these scales. In addition, a third, empirical model was generated for comparison with the West Haven-Yale and Bernstein models. DESIGN: This study used exploratory and confirmatory factor analysis on two independent samples of chronic pain patients (n = 472 and n = 346) to test hypotheses regarding the factor structure of the MPI. RESULTS AND CONCLUSION: Principal axis factor analysis resulted in an empirical model that suggested that the primary psychometric problem of the MPI was lack of item-factor discrimination for several items. When the three models were tested using confirmatory factor analysis, improvement in model fit occurred when cross loading items were excluded. Nevertheless, the goodness of fit of original factor structure was adequate, suggesting it would be premature to suggest changes in this instrument.

OBJECTIVE: The Coping Strategies Questionnaire (CSQ), a measure of coping in chronic pain patients, was subjected to item-level exploratory factor analysis. SUBJECTS: A sample of 965 chronic pain patients were used in the analysis. RESULTS: Principal components analysis using a varimax rotation procedure identified nine factors that accounted for 54.5% of the variance. Of these nine factors, the first five represent subscales of the original CSQ subscales. The catastrophizing subscale replicated with significant loadings for all six original items, and ignoring sensations replicated with five of six items. Factors representing reinterpreting pain sensations, coping self-statements, and diverting attention subscales also appeared. The items from the praying and hoping subscale split into separate praying and hoping factors (factors 6 and 8). When reliability coefficients were calculated, factors 7 through 9 had unacceptably low internal consistency and thus were not considered stable factors. Correlations between factors 1 through 6 and other measures of psychological and physical functioning were calculated in the construct validation portion of this study. Previously found relationships were replicated in that the correlations between CSQ factor scores and measures of pain, depression, and disability were in the same direction in this data set as those previously reported.

OBJECTIVE: Past research has shown response biases to influence the accuracy of results from self-report measures. In pain assessment, where a percentage of patients have financial and other reasons to minimize or exaggerate psychological disturbance, it becomes especially important to identify the influence of response bias in self-report of adjustment. This study investigated the susceptibility of three commonly used self-report pain assessment measures to response bias. DESIGN: This study used a within-subjects (asymptomatic subjects) design with two experimental conditions and nonequivalent control group (chronic pain patients). SUBJECTS: Experimental group: 40 students enrolled in an occupational therapy program at a major southeastern United States university. CONTROL GROUP: 200 subjects referred to a multidisciplinary pain clinic at a major teaching hospital. MEASURES: Coping Strategies Questionnaire, Multidimensional Pain Inventory, and Pain Beliefs and Perceptions Inventory. RESULTS: With few exceptions, asymptomatic subjects scored significantly differently on these measures while portraying themselves as either coping well or coping poorly. In addition, when using the "coping poorly" response set, asymptomatic subjects reproduced scores similar to those of symptomatic chronic pain patients. CONCLUSION: The susceptibility to manipulation appeared constant across the three measures, a finding that highlighted the difficulties clinicians and researchers encounter in accurate interpretation of results from these measures in the absence of validity indicators. This study also emphasizes the ease with which subjects with sufficient motivation can present themselves in an untruthful and manipulative manner and can generate scores that are, on their own, difficult to distinguish from those of a group of typical chronic pain patients.

Although it is clear from previous research that pain is associated with negative affect, the relative contribution of specific affective dimensions, e.g. depression, anxiety and anger, to the subjective experience of chronic pain is unclear. The literature is also mixed concerning the relative importance of state versus trait influences in the experience of chronic pain. The present study analyzed the ability of anxiety, anger, and depression (as measured by the State-Trait Personality Inventory, State-Trait Anger Expression Inventory, and the Beck Depression Inventory, respectively) to predict self-report of clinical pain as indicated by the McGill Pain Questionnaire (MPQ) in a sample of 60 chronic pain patients. The results of stepwise regression analyses consistently demonstrated that the state measures were more strongly related to MPQ pain ratings than trait measures. These data suggest support for the hypothesis that chronic pain adversely impacts mood rather than the opposing hypothesis that negative mood is a predisposing factor in the development of chronic pain. Furthermore, different aspects of the state emotional experience were found to be related to different components of pain report. The results of this study also suggest that attributional processes could be an important component of the relationship between negative mood and the experience of pain.

The diagnostic validity of an alternate form of the Rey Auditory Verbal Learning Test (AVLT) is investigated. Subjects were 73 inpatients from a VA Medical Center who were classified as having either intact (n = 41) or impaired (n = 32) memory functions. Employing a counterbalanced design, both groups were administered the standard (Form A) and alternate (Form C) forms of the AVLT. Means for the learning trials, trial VI and the recognition procedure were calculated for the intact and memory-impaired subjects and contrasted for each test. Results suggested that Form C discriminated groups at a level comparable to that of Form A. This impression was confirmed by separate stepwise discriminant analyses for Form A and Form C that yielded identical hit-rates (i.e., 75.3%) in terms of identifying subjects as memory-intact or memory-impaired. These findings suggested that Form C may be used for the assessment of persons with verbal mnemonic deficits with the same degree of confidence that has been attributed to Form A.
RESUMO
Few studies have examined the various factors related to pain during burn dressing changes. Patients' and nurses' ratings of pain and tension were obtained during 107 burn dressing changes among 11 burned patients. As found in previous studies, there was little concordance between nurses' and patients' ratings. Both nurses' and patients' ratings of pain were positively related to amount of analgesic medications administered, whereas amounts were inversely related to patients' reports of pain in a subsample of dressing changes in which anxiolytics were administered. However, these relationships failed to reach statistical significance. Multiple regression analyses revealed that ratings of tension during the procedure were significantly related to overall and worst pain, whereas amount of analgesics and anxiolytics given, postburn day, and total body surface area were not. Exploratory correlations suggested that ability to accurately discriminate between painful episodes, social desirability, and trait anxiety may be factors that significantly influence self-report of pain and might be worthwhile to study more systematically in the future. Implications for burn pain control and suggestions for future research are presented.

OBJECTIVE: To examine the impact of clinician factors on technical data within an electrodiagnostic consultation for low-back pain and spinal stenosis. DESIGN: Examiner differences on single-segment paraspinal mapping scores and other findings were examined in a prospective, masked, double-controlled trial involving 150 people aged 55-80 yrs who were selected for no symptoms, back pain, or possible spinal stenosis. RESULTS: Unmasked clinicians were more variable than masked physicians (F2,219 = 4.808, P =or<0.01) and gave lower scores to people they felt had mechanical back pain. The percentage of inadequate segmental scores differed among clinicians (0-16.6%, F8,226 = 4.170, P < 0.001), with fellows having more difficulty than faculty (11.76 +/- 32.38% vs. 0.75 +/- 8.67%) (t233 = 3.753, P < 0.001). Correction of clinician bias improved the relationship between paraspinal score and subjects' ability to walk (weighted regression R = 0.129, B = -0.047, P < 0.001; unweighted regression R = 0.090, B = -0.045, P < 0.001). CONCLUSIONS: Objective testing is adversely affected by clinician factors including prejudgment, experience, and individual idiosyncrasies. Less variation is found in more codified procedures. For electrodiagnostic consultation, correction of variability improves the relationship of test results to disability.

Assessed the validity of the Denman Memory for Human Faces (MHF) subtest employing a clinical sample. Factor analysis with marker variables was employed to establish the nature of the extracted factors. The MHF subtest, WAIS-R Verbal (i.e., Information, Vocabulary, and Digit Span) and Performance (i.e., Block Design and Object Assembly) subtests, the Wechsler Memory Scale Mental Control, Paired Associate Learning, 30-min Logical Memory, and 30-min Visual Reproduction, and Benton's Facial Recognition Test were subjected to a maximum likelihood factoring procedure with Varimax rotation. Four factors were extracted which accounted for 72.7% of the variance. Factor I was perceptual-organization, Factor II was verbal comprehension, Factor III was general memory, and Factor IV was attention-concentration. The MHF subtest achieved a substantial loading (i.e., 0.56) on the general memory factor along with Logical Memory (0.54), Visual Reproduction (0.51), and Paired Associate Learning (0.71). Clinical applications of the MHF were discussed.
