Examining the Adjustment Patterns of Adults With Multiple Chronic Pain Conditions and Multiple Pain Sites: More Pain, No Gain.

The present study examined how multiple chronic pain conditions and pain sites are associated with sociodemographics, chronic pain adjustment profiles, and emotional distress. A total of 2,407 individuals who reported at least 6 months of having consistent pain severity, pain interference, and/or emotional burden due to pain were recruited through random digit dialing across the United States. Participants' chronic pain adjustment profiles (ie, pain intensity, pain interference, emotional burden, pain catastrophizing, pain coping, pain attitudes, and social resources) were assessed. Anxiety and depressive symptoms were also measured using a subsample of 181 participants who provided 3-month follow-up data. More than 60% of individuals with chronic pain reported having multiple pain conditions. Middle-aged single women with fibromyalgia, disability and of low socioeconomic status reported a greater number of pain conditions and pain sites. Structural equation modeling revealed that a higher number of pain conditions and sites were associated with more dysfunctional chronic pain adjustment profiles. The subsample analyses showed that reporting a greater number of pain conditions predicted a higher level of depression and anxiety 3 months later, controlling for pain-related anxiety and depressive symptoms, pain severity and interference at baseline. Having multiple pain conditions and sites may represent a psychosocial barrier to successful adjustment to chronic pain. PERSPECTIVE: This article argues for the importance of assessing the number of co-occurring chronic pain conditions and bodily areas that are affected by pain in both pain research and clinical settings. Measuring and incorporating such information could potentially enhance our nascent understanding of the adjustment processes of chronic pain.

Personal resource profiles of individuals with chronic pain: Sociodemographic and pain interference differences.

PURPOSE/OBJECTIVE: Previous studies have demonstrated important associations between personal resources and pain interference. Using latent profile analysis, the present study (a) identified subgroups of individuals with chronic pain who have different personal resource profiles; (b) explored sociodemographic differences among subgroups; and (c) examined how these subgroups differ in pain interference. Research Method/Design: Study 1 is based on daily diary and survey data from 220 individuals with fibromyalgia (FM). Study 2 is based on 4 annual surveys of 483 individuals with long-term neurological/neuromuscular disease or injury, and chronic pain. Modifiable personal resource variables including sense of resilience, social support, pain acceptance, and sleep quality were included in latent profile analyses. RESULTS: Three subgroups were identified in both studies: High, Moderate, and Low Personal Resource groups. In both studies, annual income level was significantly different among subgroups. Study 1 results showed a significant between-groups difference in pain interference across 21-days only between High and Moderate Personal Resource groups controlling for the level of pain intensity and depressive symptoms. In Study 2, however, all subgroups were significantly different with respect to their levels of pain interference at baseline over and above various covariates, with the Low Personal Resource group reporting the highest level of pain interference at baseline. These baseline differences remained stable over 4 years. CONCLUSIONS/IMPLICATIONS: The findings suggest a robust association between economic disparity and personal resource profiles among individuals with chronic pain. The role of different personal resource profiles in pain interference appears to differ by chronic pain condition. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Psychosocial correlates of chronic pain and depression in young adults: further evidence of the utility of the Profile of Chronic Pain: Screen (PCP: S) and the Profile of Chronic Pain: Extended Assessment (PCP: EA) battery.

OBJECTIVE: The goals of the present studies were 1) to determine the psychometric utility and norms of the Profile of Chronic Pain: Screen (PCP: S) in young adults (ages 17-24) with self-reported pain and 2) to compare non-, mildly-, and clinically-depressed young adults with chronic pain in their patterns of pain attitudes and pain beliefs as assessed by the Profile of Chronic Pain: Extended Assessment (PCP: EA) battery. METHODS: Participants in the first study included 2,475 male and female college students drawn from undergraduate introductory psychology classes in a large western (U.S.) university. Study 2 participants were 275 male and female introductory psychology students, screened for chronic pain and depression from a cohort of 1,266 students. RESULTS: Study 1 results confirmed the utility of the PCP: S as a screening tool for pain problems in young adults. Study 2 revealed that, although not differing in pain severity, clinically depressed participants differed from their nondepressed and mildly depressed peers in terms of enhanced catastrophizing tendencies and greater perceived disability. Both depressed groups scored lower on control beliefs than the nondepressed group. Moreover, the clinically depressed students reported the highest scores on pain-induced fear, differing from both the mildly depressed and the nondepressed. Finally, the three groups did not differ in their belief in a medical cure. CONCLUSIONS: Results suggest that depressed young persons with chronic pain demonstrate a pattern of negative attitudes and beliefs that could compromise their ability to flexibly adjust to changing life circumstances.

Evaluating chronic pain impact among patients in primary care: further validation of a brief assessment instrument.

OBJECTIVE: To evaluate the psychometric properties of the Profile of Chronic Pain: Screen (PCP:S) in primary care. The PCP:S is a brief assessment device designed to gauge pain severity, interference, and emotional burden. DESIGN: Questionnaire survey with short-term reliability and validity follow-up. METHODS: Two hundred and forty-four outpatients (52% female) with chronic pain recruited from five primary care settings completed the 15-item PCP:S at an initial testing session. Approximately 1 week later, two subgroups participated in a retest reliability and validity follow-up. The battery of follow-up questionnaires included a measure of social desirability response bias and several instruments designed to provide convergent validity for the PCP:S. RESULTS: Retest reliability, internal consistency, factor structure, and social desirability bias were all found to be acceptable. Likewise, preliminary evidence suggests that, by virtue of its correlation with established measures of pain adjustment, the PCP:S is a valid pain assessment device. CONCLUSIONS: Although the PCP:S was initially developed and validated using a national community sample of adults with chronic pain who provided data via telephone interviews, the present findings support its use as a brief and psychometrically sound paper-and-pencil measure for the assessment of three key components of chronic pain in primary care.

The development and preliminary validation of the Profile of Chronic Pain: Extended Assessment Battery.

The aim of the present research was the development and validation of a set of instruments, collectively called the Profile of Chronic Pain: Extended Assessment Battery (PCP:EA), designed to be administered to adults (between the ages of 25 to 80) after establishing the existence of a chronic pain problem. The final 86-item version of the PCP:EA consisted of 33 single items assessing: pain location and severity, pain characteristics (e.g. worst daily pain), medication use, health care status, the identity of the most important person in the patient's life, and functional limitations in 10 areas of daily living. In addition, the PCP:EA includes 13 multi-item subscales addressing aspects of coping (guarding, ignoring, task persistence, and positive self-talk), catastrophizing, pain attitudes and beliefs (including disability beliefs, belief in a medical cure for pain, belief in pain control, and pain-induced fear), and positive (tangible and emotional) and negative (insensitivity and impatience) social responses. Data were obtained from two national samples which were recruited and screened via a random-digit dialing telephone interview procedure. Stratified sampling was employed to assure equal gender and age group representation across three age groupings (25-44; 45-64; 65-80). Two survey studies provided strong evidence for the hypothesized factor structure, internal consistency, independence from response bias, and validity of the PCP:EA. Moreover, the presence of normative data enhance the diagnostic and prescriptive utility of the instrument.

The Assessment of Adult Health Care Orientations: Development and Preliminary Validation of the Multidimensional Health Profile-Health Functioning Index (MHP-H) in a National Sample.

This paper describes the development and preliminary validation of the Multidimensional Health Profile-Health Functioning Index (MHP-H), a 69-item self-report instrument designed to assess a variety of behaviors, perceptions, attitudes, and beliefs presumed to influence health status and the pursuit of lay and professional health care. The MHP-H briefly measures adult health history, health habits, health care utilization, health beliefs and attitudes, and response to illness (help-seeking behaviors). A national sample of adults (N = 673) was assessed, comprising 3 age groupings (18-32, 33-50, and 51-89) crossed with gender and then further subdivided into several subsamples for purposes of reliability and validity assessment. In addition, a group of spouse "key informants" was also recruited. Preliminary validation of single-item indicators as well as confirmatory factor analyses of multi-item scales was achieved. The present findings support the psychometric and practical utility of the MHP-H and warrant its use by health psychologists in a variety of research and applied settings.
