Exploring the Relationship Between Attachment and Pathological Personality Trait Domains in an Outpatient Psychiatric Sample.

ABSTRACT: The current study investigates the relationship between insecure attachment and pathological personality trait domains in a sample of psychiatric outpatients. Participants ( N = 150) completed measures for attachment and personality. Bivariate correlations and multiple regression analyses investigated the extent to which insecure attachment and personality pathology were associated. Insecure attachment positively correlated with overall personality pathology, with attachment anxiety having a stronger correlation than attachment avoidance. Distinct relationships emerged between attachment anxiety and negative affectivity and attachment avoidance and detachment. Insecure attachment and male sex predicted overall personality pathology, but only attachment anxiety predicted all five trait domains. Insecure attachment might be a risk factor for pathological personality traits. Assessing attachment in clinical contexts and offering attachment-based interventions could benefit interpersonal outcomes.

The relationship between attachment, treatment compliance and treatment outcomes in patients with obstructive sleep apnea.

OBJECTIVE: Obstructive sleep apnea (OSA) is a common condition with numerous health and psychological consequences. While treatment with Continuous Positive Airway Pressure (CPAP) is highly effective, it seems to be impacted by interpersonal aspects of the patient. The current study explores the role of two major interpersonal descriptors (attachment and relationship satisfaction) on treatment initiation and compliance with CPAP. The benefit of CPAP treatment on sleep measures and psychological functioning is also examined. METHODS: Participants in stable relationships, diagnosed with OSA following an inpatient polysomnography test (N = 83), were recruited. Participants were appraised on their decision to initiate treatment and completed interpersonal measures (couples' satisfaction, attachment dimensions) as well as sleep measures and mental health measures. Participants were invited to repeat the measures after 3 months (N = 31 agreed). Associations between interpersonal measures and CPAP initiation and compliance as well as the impact of CPAP on sleep and all psychological measures was assessed. RESULTS: Individuals with high attachment anxiety pursued OSA treatment based on a mutual decision with the partner, while individuals with lower attachment anxiety made the decision themselves. Couples' satisfaction was positively associated with CPAP compliance over 3 months. CPAP compliance significantly improved sleep measures, mood and anxiety symptoms. CONCLUSION: The study brings evidence for a positive role of interpersonal factors in the initiation and compliance with OSA treatment as well as longitudinal benefits on sleep, mood and anxiety levels. The results can inform clinical approaches meant to increase treatment engagement and adherence in OSA patients through psychoeducation.

An exploration of adult attachment insecurity and psychiatric symptoms in individuals with obstructive sleep apnea.

OBJECTIVE: Obstructive sleep apnea (OSA) is a common sleep disorder, often associated with multiple medical comorbidities as well as psychological difficulties. Among the latter, relationship difficulties as well as mood and anxiety symptoms have been reported, without a clear understanding of the mechanism. In the current study we wanted to further explore these aspects, while comparing groups of OSA individuals with good vs poor sleep. The primary goal of the study was to examine the relationship between sleep and adult attachment and secondly to explore the relationship between sleep and couple satisfaction as well as symptoms of depression and anxiety. METHODS: Following diagnosis of OSA by overnight polysomnography, 102 participants completed several psychological measures (e.g. adult attachment, couple satisfaction, depression and anxiety symptoms) and sleep measures (sleep quality and daytime sleepiness). Variables of interest were compared between the OSA groups with either good/poor sleep quality or no/excessive daytime sleepiness. RESULTS: Adult attachment avoidance was higher in individuals with low sleep quality (mean difference = 0.33, p = .04, d = 0.46) while adult attachment anxiety was higher in individuals with high daytime sleepiness (mean difference = 0.46, p = .04, d = 0.43). Individuals with either poor sleep quality or excessive daytime sleepiness had greater severity of depression and anxiety (both p < .05). CONCLUSIONS: OSA patients with poor sleep quality and excessive daytime sleepiness have greater attachment insecurity and higher levels of depression and anxiety. A multidisciplinary approach including psychological interventions, should be considered in OSA cases with high levels of sleep disturbance.

Validation of a Limitations in Daily Activities Scale for Chronic Pain.

Limitations in physical function and participation are important domains of assessment in chronic pain. In 1995, the International Association for the Study of Pain distributed a self-report measure of functional limitations. Although the questionnaire has been used in research studies, it has never been subjected to a thorough investigation of its measurement properties. In this study, 941 patients with chronic pain completed the 16-item Limitations in Daily Activities Scale (LIDAS) at 2 pretreatment and 1 post-treatment assessment points. Individual item analysis favored a 13-item scale. This 13-item LIDAS had a confirmed 3-factor structure consisting of limitations in personal care, global participation, and specific tasks. Reliability analyses for the total scale (α = .90), as well as for each factor individually (αs = .82-.84), indicated good internal consistency, test-retest reliability (intraclass correlations = .65-.88 over varying time intervals), and responsiveness to change with treatment. LIDAS scores correlated as expected with measures of pain intensity, pain cognitions, and depression, as well as with other self-report and clinician-administered measures of functional performance. Using patient global ratings as anchors, a minimal clinically important difference of 5 points was established as a criterion for meaningful individual improvement after treatment. In conclusion, the LIDAS is a reliable, valid, and clinically relevant option for assessing limitations in physical function and participation in patients with chronic pain. PERSPECTIVE: Physical function and participation comprise a core dimension in the assessment of chronic pain. This study demonstrates that the LIDAS is a reliable and valid measure of this dimension, with good applicability for documenting clinically important change with treatment.

A Network Analysis of Depressive Symptoms in Individuals Seeking Treatment for Chronic Pain.

OBJECTIVES: Major depression in the context of chronic pain has been conceptualized implicitly as a latent variable, in which symptoms are viewed as manifestations of an underlying disorder. A network approach provides an alternative model and posits that symptoms are causally connected, rather than merely correlated, and that disorders exist as systems, rather than as entities. The present study applied a network analysis to self-reported symptoms of major depression in patients with chronic pain. The goals of the study were to describe the network of depressive symptoms in individuals with chronic pain and to illustrate the potential of network analysis for generating new research questions and treatment strategies. MATERIALS AND METHODS: Patients (N=216) admitted to an interdisciplinary chronic pain rehabilitation program provided symptom self-reports using the Patient Health Questionnaire-9. Well-established network analyses methods were used to illustrate the network of depressive symptoms and determine the centrality of each symptom (ie, the degree of connection with other symptoms in the network). RESULTS: The most central symptoms were difficulty concentrating, loss of interest or pleasure, depressed mood, and fatigue, although the relative position of each symptom varied slightly, depending on the centrality measure considered. DISCUSSION: Consistent with past research with patients undergoing treatment for major depression, the current findings are supportive of a model in which depressive symptoms are causally connected within a network rather than being manifestations of a common underlying disorder. The research and clinical implications of the findings, such as developing treatments targeting the most central symptoms, are discussed.

Relationships between patients' attachment characteristics and views and use of psychiatric treatment.

This study explored the influence of attachment on psychiatric treatment by considering attitudes towards and the use of psychotropic medication and psychotherapy in patients with depressive and anxiety disorders. Adults referred to a psychiatrist completed self-report measures and participated in a diagnostic interview based on DSM-IV criteria. Those with depressive, anxiety or adjustment disorders were included (n = 124). Patients reported the types and dosage of current psychotropic medication as well as number of different psychiatrists and psychologists/counselors they had seen in the past 10 years. Multiple regression analyses were used to examine relationships between attachment anxiety and avoidance and the variables capturing treatment use and attitudes towards treatments. Attachment anxiety was positively associated with the number of current psychiatric medications and with both the number of psychiatrists and the number of psychologists/counselors seen. Attachment avoidance was negatively associated with the number of current psychotropic medications and beliefs about the efficacy of psychotherapy. The findings suggest that patients' attachment characteristics play a role in their views and choices regarding treatments. Developing treatments sensitive to the needs of insecurely attached individuals may lead to improved treatment outcomes.

Do Pain-Related Support Preferences Moderate Relationships Between Chronic Pain Patients' Reports of Support Received and Psychosocial Functioning?

OBJECTIVE: The operant theory of chronic pain and related research suggest pain-related solicitous support promotes disability. The current study investigated the hypotheses that solicitous support is positively associated with both disability and relationship satisfaction and that these relationships are moderated by the level of desire for this type of support. METHODS: Patients with chronic pain (N = 147) and in a relationship were recruited from a multidisciplinary pain treatment center. They provided self-reports of the amount of three types of pain-related support wanted and received (i.e., solicitous, encouragement, and suppression), disability, and relationship satisfaction. RESULTS: A hierarchical regression analysis indicated that solicitous support received was not significantly associated with disability. However, a moderation effect was found regarding encouragement. Encouragement received was negatively associated with disability, and this relationship was strongest at lower levels of interest in encouragement. Solicitous support received had a large positive association with relationship satisfaction. CONCLUSIONS: The findings suggest the influence of pain-related support is more complex than suggested by the operant conditioning model of chronic pain, which emphasizes the possible detrimental impact of solicitous support. Further research is warranted regarding the potential relationship enhancing effects of solicitous support and the influence of encouragement on disability experienced by those with chronic pain.

Self-perceived burden, perceived burdensomeness, and suicidal ideation in patients with chronic pain.

Background: Self-perceived burden and perceived burdensomeness are two apparently related constructs that have arisen independently from research in physical and mental health, respectively. Although both are associated with suicidal ideation in individuals with chronic pain, they have yet to be examined concurrently in the same group of patients. Aims: The aim of this study was to investigate the relationship between the two constructs and their differential prediction of suicidal ideation. Methods: Participants were 260 outpatients of an interdisciplinary chronic pain treatment program. Each participant completed the Self-Perceived Burden Scale (SPBS), the Interpersonal Needs Questionnaire Perceived Burdensomeness Scale (INQPBS), the Beck Scale for Suicide Ideation, and the thoughts of self-harm item of the Patient Health Questionnaire-9. Results: The SPBS and the INQPBS were both unifactorial measures with good internal consistency. They correlated significantly with one another (r = 0.50, P < 0.001), as well as with scores on the two measures of suicidal ideation (rs ranging from 0.29 to 0.62, Ps < 0.001). However, the INQPBS correlated more highly with suicidal ideation than did the SPBS. In regression analyses, the INQPBS predicted unique variance in suicidal ideation after adjusting for the SPBS. Conversely, the SPBS did not contribute uniquely when the INQPBS was entered first. Conclusions: Patients with chronic pain who believe that they have become "a burden to others" are at increased risk for suicidal ideation. The conceptual similarities and differences between the constructs of self-perceived burden and perceived burdensomeness are reviewed to explain why perceived burdensomeness is the stronger predictor of this increased risk.

Contexte: La perception de soi comme un fardeau et le fardeau perçu sont deux construits connexes qui ont respectivement émergé de travaux de recherche en santé physique et en santé mentale, de manière indépendante. Bien qu'ils soient tous deux associés à l'idéation suicidaire chez les individus souffrant de douleur chronique, ils n'ont jamais été évalués simultanément au sein du même groupe de patients. Objectifs: Examiner le lien entre les deux construits et leur prédiction différentielle de l'idéation suicidaire. Méthodes: Le groupe de participants était composé de 260 patients externes d'un programme interdisciplinaire de gestion de la douleur chronique. Chaque participant a rempli le Self-Perceived Burden Scale (SPBS), l'Interpersonal Needs Questionnaire Perceived Burdensomeness Scale (INQPBS), l'Échelle d'idéation suicidaire de Beck et l'énoncé portant sur les pensées d'automutilation du Questionnaire sur la santé des patients-9.Résultats: Tant les mesures du SPBS que celles de l'INQPBS étaient monofactorielles et présentaient une bonne cohérence interne. Elles présentaient une corrélation significative l'une avec l'autre (r = 0,50, p < 0,001) et avec les scores obtenus pour les deux mesures de l'idéation suicidaire (r = de 0,29 à 0,62, p < 0,001), Toutefois, l'INQPBS présentait une plus grande corrélation avec l'idéation suicidaire que le SPBS. Dans les analyses de régression, l'INQPS était un prédicteur de variance unique dans l'idéation suicidaire après rajustement en fonction du SPBS. Inversement, le SPBS ne contribuait pas de manière unique lorsque l'INQPBS était inscrit en premier.Conclusions: Les patients souffrant de douleur chronique qui croient qu'ils sont devenus « un fardeau pour les autres ¼ sont à plus grand risque d'idéation suicidaire. Les similarités et les différences conceptuelles entre les construits de perception de soi comme un fardeau et de fardeau perçu sont examinées afin d'expliquer pourquoi le fardeau perçu est le meilleur prédicteur de ce risque accru.

The Effect of Social Observational Learning, Empathy and Catastrophizing in Chronic Pain Patients During Acute Pain Induction.

Objective: In this study, we were interested in determining whether we could alter a pain response in a chronic pain patient population by exposing participants to different videos prior to inducing acute pain. Design: This observational case series study required participants to report their pain level during the cold pressor task after viewing an instruction video. Setting: Recruitment and testing took place in a tertiary care multidisciplinary pain center. Subjects: Forty adults with chronic pain participated in the study and completed the cold pressor test. Methods: Prior to testing, questionnaires measuring pain, empathy, and catastrophic thinking were completed and participants were randomized to view an instructional video where an actress either demonstrated pain behavior or a stoic response during the cold pressor test. Results: Participants with higher levels of catastrophizing reported higher pain levels during the cold pressor test. Personal Distress Empathy measures of participants who viewed the pain catastrophizing video were significantly correlated with their final pain reports. Following the cold pressor task, participants' pain reports for their primary chronic pain sites were significantly reduced. Conclusions: These results support previous findings that people with chronic pain show the tendency toward increased acute pain experience if levels of catastrophizing and Personal Distress Empathy measures are higher. Participants reported attenuated chronic pain following induced pain, also in line with previous research suggesting a central endogenous inhibitory effect. Our findings shed light on the role of emotional and social components affecting the experience of pain in individuals with chronic pain.

Testing the Interpersonal Theory of Suicide in Chronic Pain.

OBJECTIVE: The interpersonal theory of suicide offers a conceptual framework for understanding suicidal ideation (SI) that may be applicable to individuals with chronic pain. The theory emphasizes the importance of 2 interpersonal constructs as precursors to SI: perceived burdensomeness (the belief that one has become a burden to others) and thwarted belongingness (a lack of social integration or connection). Our objective was to test the interpersonal theory of suicide in people with chronic pain. METHODS: Hierarchical regression analysis was used in a cross-sectional study of 282 patients of an interdisciplinary pain clinic. The Beck Scale for Suicide Ideation was the criterion measure of SI, and independent variables included both general and pain-specific predictors. RESULTS: After adjusting for other known or putative risk factors related to pain and mental health, perceived burdensomeness significantly predicted SI, whereas thwarted belongingness did not. As expected according to theory, the interaction between perceived burdensomeness and thwarted belongingness was also significant; perceived burdensomeness was a strong predictor of SI at high levels of thwarted belongingness, but only marginally at low levels. Other independent predictors were male sex, number of prior suicide attempts, and hopelessness. DISCUSSION: These findings are in line with some, but not all, of the major predictions of the interpersonal theory of suicide. In general, however, they support the relevance of the theory for individuals with chronic pain.

A brief cognitive-behavioral intervention for sleep in individuals with chronic noncancer pain: A randomized controlled trial.

PURPOSE/OBJECTIVE: Chronic pain has a significant negative impact on the quality of life, including sleep disruption. There is compelling evidence that cognitive-behavioral therapy can be effective in treating sleep disorders. To our knowledge, no research has been carried out on brief cognitive-behavioral educational interventions in individuals with chronic pain. This study was conducted to determine whether a brief education session that incorporates sleep hygiene and cognitive-behavioral strategies would help improve the sleep of individuals with chronic pain. RESEARCH METHOD/DESIGN: Eighty-five patients from a tertiary care Multidisciplinary Pain Centre completed all aspects of the study. This sample was randomized into 2 groups: a treatment group who received a brief cognitive-behavioral educational session, and a control group who did not. All participants completed a daily sleep diary for 28 days. Measures on sleep quality, beliefs and attitudes about sleep, pain, disability, and mood were recorded at baseline. RESULTS: No significant differences were found between groups on demographic, pain, disability, mood measures, or sleep quality at baseline. Overall, 42% of the individuals who completed this study had depression scores above the clinical cutoff. This sample reported a high level of pain-related disability. Individuals in the treatment group had significantly reduced sleep onset latency compared to controls. No significant differences between groups on the number of times waking or hours slept. CONCLUSIONS/IMPLICATIONS: Our findings suggest that there is potential for a brief educational intervention to have a positive impact on some aspects of sleep in the chronic pain population.

Attachment insecurity predicts responses to an interdisciplinary chronic pain rehabilitation program.

The aim of this study was to examine the hypothesis that attachment insecurity is associated with poorer responses to interdisciplinary treatment for chronic pain. Patients (n = 235) admitted to a 4-week interdisciplinary rehabilitation program were recruited. At pre-treatment, participants completed a battery of questionnaires assessing adult attachment styles and dimensions, as well as pain intensity, disability, self-efficacy, pain catastrophizing, and depressive symptoms. The latter measures were completed again at post-treatment. Nearly two-thirds of participants (65.5 %) reported having an insecure attachment style. Attachment insecurity was unrelated to pre- and post-treatment reports of pain intensity and pain-related disability, but was significantly associated with most other clinical variables at both time points. Regression analyses controlling for pre-treatment functioning indicated that attachment insecurity was associated with less improvement in pain catastrophizing, pain self-efficacy, and depressive symptoms. Further research is warranted to investigate the processes by which attachment characteristics influence patients' responses to chronic pain rehabilitation.

Relationships between adult attachment style ratings and sleep disturbances in a nationally representative sample.

OBJECTIVE: Recent research with small non-clinical and clinical samples suggests a positive association between attachment insecurity and sleep disturbances. The present study extends this line of research by exploring this relationship in a large sample of the U.S. population and by statistically adjusting for health conditions and psychiatric disorders as potential confounds. METHOD: The data used were from the National Comorbidity Survey Replication (N=5692). The main interview consisted of the Composite International Diagnostic Interview used to assess psychiatric diagnoses. Ratings of three adult attachment styles (viz., secure, avoidant, and anxious) were obtained along with self-reports of health conditions and four sleep disturbances (viz., difficulty initiating sleep, difficulty maintaining sleep, early morning awakening, and daytime sleepiness). RESULTS: Bivariate logistic regression analyses indicated that ratings of secure attachment were negatively associated with each sleep disturbance and ratings of insecure attachment were positively associated with each sleep disturbance. Multivariate logistic regression analyses were used to examine associations between the attachment ratings and sleep disturbances while statistically controlling for sociodemographic variables, the presence of a health condition, and psychiatric disorders (viz., depressive disorders, bipolar disorders, anxiety disorders, alcohol/substance disorders, and attention deficit disorder). With one exception, the insecure attachment ratings continued to be positively associated with sleep disturbances. CONCLUSION: The findings demonstrate that attachment insecurity is related to sleep disturbances independent of health conditions and concurrent psychiatric disorders. Research aimed at delineating the mechanisms responsible for these associations is warranted.

Psychometric evaluation and refinement of the Pain Response Preference Questionnaire.

BACKGROUND: The Pain Response Preference Questionnaire (PRPQ) assesses preferences regarding pain-related social support. The initial factor analytical study of the PRPQ produced four empirically supported scales labelled Solicitude, Management, Encouragement and Suppression. A second study produced similar findings, but suggested that the Management and Encouragement scales be combined into a single scale labelled Activity Direction. OBJECTIVES: To use factor analytical methods to evaluate these competing configurations of the PRPQ (ie, three versus four scales) and to further refine the measure. The ability of the PRPQ scales to account for pain severity and disability ratings was also evaluated. METHODS: Chronic pain patients (n=201) completed the PRPQ along with the Pain Catastrophizing Scale (PCS) and self-reports of pain severity and disability. RESULTS: Confirmatory factor analysis indicated that both models tested provided a poor fit to the data. A follow-up exploratory factor analysis was used to further refine the PRPQ scales and resulted in scales labelled Solicitude, Encouragement and Suppression. Supportive of the potential clinical utility of the PRPQ, Suppression was positively associated with pain severity and Solicitude was positively associated with disability. These two scales were also positively associated with the PCS. Supportive of the incremental validity of the PRPQ, a multiple regression analysis indicated that the Solicitude scale accounted for unique variance in disability ratings beyond that accounted for by demographic/clinical variables and the PCS. CONCLUSIONS: The PRPQ has promise as a clinical assessment measure and for advancing research examining the interpersonal context of pain.

A longitudinal investigation of pain-related social support preferences in a chronic pain treatment sample.

OBJECTIVES: Chronic pain patients' pain-related social support preferences have received little clinical or research attention. However, recent research utilizing the Pain Response Preference Questionnaire (PRPQ) has indicated that such preferences are related to pain-related disability. This study investigated whether pain-related social support preferences: (1) were related to disability levels, (2) predicted changes in pain and disability following a group-based treatment program, and (3) changed from pretreatment to posttreatment. METHODS: At pretreatment and posttreatment, chronic pain patients (N=45) participating in a self-management psychoeducation program completed the PRPQ and measures of pain severity and disability. RESULTS: A multiple regression analysis indicated that at pretreatment the Solicitude scale of the PRPQ was positively associated with disability, and that this association was moderated by the other 2 PRPQ scales (Activity Direction and Suppression). The PRPQ scales did not predict changes in pain or disability and there were no significant changes in the PRPQ scale scores. However, participants did not respond to the Solicitude scale in a consistent manner from pretreatment to posttreatment (51.1% decreased, 35.5% increased, and 13.3% remained the same). These changes were unrelated to changes in pain or disability. DISCUSSION: Additional research aimed at identifying the processes underlying the association between pain-related support preferences and disability is warranted. Given the potentially important role that a desire for solicitous support may play in shaping the social context of pain, understanding the unexpected changes in Solicitude scale scores found in the present study may be particularly important for improving self-management treatments for chronic pain.

Change in suicidal ideation after interdisciplinary treatment of chronic pain.

OBJECTIVES: To examine suicidal ideation (SI) in individuals with chronic pain, especially change in suicidal thinking after interdisciplinary treatment. MATERIALS AND METHODS: Consecutive patients (n=250) admitted to a 4-week, group-based chronic pain management program completed measures of pain intensity, functional limitations, depressive symptoms, overall distress, pain catastrophizing, self-perceived burden, and SI at pretreatment and posttreatment. RESULTS: Before treatment, 30 (12.0%) participants were classified as having a high level of SI, 56 (22.4%) had a low level of SI, and 164 (65.6%) reported none. After treatment, there was a significant reduction in SI and improvements in all other outcomes, but there were still some individuals with high (n=22, 8.8%) or low (n=28, 11.2%) levels at discharge. Patients with high SI at baseline differed from those with no suicidal thinking on pretreatment and posttreatment measures of depression, distress, catastrophizing, and self-perceived burden, but not on pain intensity or functional limitations. Patients high in SI endorsed greater pain catastrophizing and self-perceived burden than those low in suicidal thinking. Sustained SI after treatment was associated with higher baseline levels of suicidal thinking and self-perceived burden to others, as well as a more limited overall response to treatment. DISCUSSION: SI was common in individuals with chronic pain, although mostly at a low level. Interdisciplinary treatment may result in reduced suicidal thinking; however, some patients continue to express thoughts of self-harm. Future studies could examine processes of change and interventions for treatment-resistant suicidal concerns.

Chronic pain and the interpersonal theory of suicide.

OBJECTIVE: Chronic pain is a known risk factor for suicide. To date, however, few studies of people with chronic pain have tested specific predictions about suicidal ideation that are derived from theory. The interpersonal theory of suicide proposes that the psychological constructs of thwarted belongingness and perceived burdensomeness are unique and independent precursors to suicidal ideation. We tested this hypothesis in a clinical sample of patients with chronic pain. METHOD: A total of 303 patients of a chronic pain rehabilitation program completed measures of pain severity, duration, and disability; cognitive-affective measures of depression and catastrophizing; and interpersonal measures of relationship distress and self-perceived burden to others. The latter measures were included as indices of the belongingness and burdensomeness constructs. Participants also rated two items pertaining to suicidal ideation. RESULTS: In a multiple regression analysis, both distress in interpersonal relations (ß = 0.12, p = .037) and self-perceived burden to others (ß = 0.25, p < .001) were significant predictors of suicidal ideation, even after adjusting statistically for demographic characteristics, pain severity and duration, functional limitations, catastrophizing, and depression. CONCLUSIONS: These findings suggest that the interpersonal theory is relevant to understanding elevated rates of suicidal ideation among people with chronic pain, and may have broader applicability to other populations with chronic illness or disability.

Associations between pain conditions and borderline personality disorder symptoms: findings from the National Comorbidity Survey Replication.

OBJECTIVES: Associations between 4 forms of pain (ie, arthritis, severe/frequent headaches, chronic spinal pain, and other chronic pain) and borderline personality disorder (BPD) symptoms were investigated in the general population. METHODS: Data from part II of the National Comorbidity Survey Replication (N=5692) were used. Pain conditions were assessed with self-reports. Arthritis was assessed on a lifetime basis. For the other pain conditions, variables were created to identify those with a remitted condition and those experiencing the condition in the past year. BPD symptoms were assessed with items from the International Personality Disorder Examination Screening Questionnaire. Axis I disorders were assessed with the Composite International Diagnostic Interview. RESULTS: Multiple regression analyses adjusting for sociodemographic variables and past-year psychiatric disorders indicated that those with a history of each pain condition (either remitted or past-year) had higher levels of BPD symptoms relative to those with a lifetime absence of the condition. For each condition, follow-up analyses indicated that those experiencing the condition in the past year had higher levels of BPD symptoms than those reporting a remitted condition. After adjusting for axis I psychiatric disorders, only the difference between the remitted and past-year severe/frequent headache groups remained significant. DISCUSSION: This is the first study to demonstrate that BPD symptoms are positively associated with chronic spinal pain, severe/frequent headaches, and other chronic pain conditions in a sample representative of the general population. The findings also suggest that relationships between remitted pain conditions and BPD symptoms warrant additional study.

Self-perceived burden in chronic pain: relevance, prevalence, and predictors.

Chronic pain is a debilitating condition that can have an impact on various facets of interpersonal functioning. Although some studies have examined the extent to which family members are affected by an individual's chronic pain, none have examined patients' perceptions of feeling that they have become a burden to others. Research on self-perceived burden in different medical populations, such as cancer, amyotrophic lateral sclerosis, and stroke, has shown that it is associated with physical symptoms and, more robustly, with psychological difficulties and concerns. The present study examined the prevalence and predictors of self-perceived burden in a tertiary chronic pain sample. Participants were consecutive patients (N = 238) admitted to an outpatient, interdisciplinary, chronic pain management program at a rehabilitation hospital. At admission, participants completed a battery of psychometric questionnaires assessing self-perceived burden, as well as a number of clinically relevant constructs. Their significant others (n = 80) also completed a measure of caregiver burden. Self-perceived burden was a commonly reported experience among chronic pain patients, with more than 70% of participants endorsing clinically elevated levels. It was significantly correlated with pain intensity ratings, functional limitations, depressive symptoms, attachment anxiety, pain self-efficacy, and caregiver burden. Self-perceived burden was also correlated with an item assessing suicidal ideation. In a hierarchical regression model, depressive symptoms, pain self-efficacy, and adult attachment significantly predicted self-perceived burden after controlling for demographic and pain-related variables. In conclusion, self-perceived burden is a clinically relevant and commonly reported interpersonal experience in patients with longstanding pain.

A psychometric evaluation of the Pain Response Preference Questionnaire in a chronic pain patient sample.

OBJECTIVE: The Pain Response Preference Questionnaire (PRPQ) assesses preferences regarding pain-related social support. The initial factor analytic study of the PRPQ conducted with a nonclinical sample identified scales labeled Solicitude, Management, Suppression, and Encouragement. The first aim of the current study was to evaluate whether these scales would be appropriate for use with chronic pain patients. The construct validity of the emerging scales and their relations to pain-related disability were also investigated. METHODS: A large sample of chronic pain patients (N = 300) completed the PRPQ along with self-reports of personality constructs, coping styles, pain severity, and disability. RESULTS: Factor analysis supported a three-factor solution. Two factors were similar to those obtained in its initial evaluation, and were given the identical labels of Solicitude and Suppression. The remaining factor was labeled Activity Direction and was comprised primarily of items that were part of the earlier Management and Encouragement scales. Internally consistent PRPQ scales based on these factors were created. Correlation analyses involving the personality and coping measures provided support for the construct validity of these PRPQ scales. Supportive of their clinical utility, multiple regression analyses indicated that, after adjusting for pain severity, the PRPQ scales accounted for significant variance in disability ratings. CONCLUSIONS: Additional factor analytic research aimed at identifying the most appropriate set of PRPQ scales is warranted. The present findings indicate that the PRPQ scales used in the current study have strong psychometric properties and hold promise as research and clinical tools.
