METHODS: The CDS was administered to 150 consecutive patients evaluated in an outpatient psychiatry consultation program.
RESULTS: CDS scores were normally distributed and had significant interitem correlations and test-retest reliability (r = 0.68). As expected, subjects with chronic pain (N = 100) had higher mean CDS scores than those without chronic pain (t = 5.6, p = .000). CDS scores were independent of demographic variables and measures of anxiety, depression, alexithymia, and somatic amplification.
CONCLUSIONS: These results suggest that counterdependency can be described by a distinct and measurable cluster of traits associated with chronic pain.
Key Words: counterdependency pain alexithymia scale depression
Abbreviations: CDS = Counterdependency Scale; BSI = Brief SymptomInventory; TAS-20 = Twenty-Item Toronto Alexithymia Scale; SSAS = Somatosensory Amplification Scale; MMPI = MinnesotaMultiphasic Personality Inventory.

In a case series of patients with chronic traumatic pain, Ford (2) noted that patients tended to start work in childhood and take on excessive responsibility. Coen and Sarno (3) described emotional inhibition with avoidance of conflict in a case series of patients with chronic back pain.
Controlled studies have had similar findings. Pilowsky and Bassett (4) compared 114 patients at a pain clinic with 53 psychiatric inpatients with depression using an illness behavior questionnaire. Among the pain patients, they found that "the salient feature was denial of both affective disturbance and life problems." Maruta et al. (5) compared the academic and work histories of 26 depressed psychiatric inpatients with those of 26 age- and sex-matched inpatients having lower back pain. They reported that the pain patients had less formal education but were likely to start work at an earlier age.
In a 13-month longitudinal study of 46 amputees, Parkes (6) discovered that the development of phantom limb pain correlated with personality traits of compulsive self-reliance, rigidity, and emotional suppression. Blumer and Heilbronn (7) documented detailed social and occupational histories in 129 pain clinic patients whose pain did not appear to have a somatic basis and in a comparison group of 30 patients diagnosed with rheumatoid arthritis. They reported that the "pain-prone" patients were significantly more likely to idealize spousal relationships and to have "ergomania" with work beginning at an early age, chronic overtime, and work without vacations.
To our knowledge, Barsky (8) was the first investigator to use the term "counterdependent" to summarize the personality characteristics of patients with chronic pain. Further research, however, has been limited by the lack of a validated scale or questionnaire that quantifies counterdependent traits. In the study reported here, we examined the use of the CDS, a five-item self-rated questionnaire, among patients seen for outpatient psychiatric consultation. Each item on the scale was designed to elicit each of the five counterdependency traits identified in the abovementioned studies of chronic pain populations: emotional suppression, idealization of relationships, strong work ethic, caregiver role-identity, and self-reliance (see Table 1 ). Patients rate their agreement with each item on a five-point Likert scale with "strongly agree" and "strongly disagree" as the end points.

DSM-IV diagnoses and social, developmental, and occupational histories were obtained in semistructured psychiatric interviews by a board-certified psychiatrist (R.J.G.). Patients referred to the outpatient consultation program were also administered a series of questionnaires before each interview, including the BSI for anxiety and depression, TAS-20, SSAS, and CDS.
The BSI is a symptom checklist derived from the Hopkins Symptom Checklist (SCL-90) and has been shown to have good validity and reliability (9). The Toronto Alexithymia Scale and its two modified versions, TAS-R and TAS-20, are currently the most commonly used and best researched measures of alexithymia (10, 11). High rates of alexithymia have been found in patients with posttraumatic stress disorder, eating disorders, panic disorder, and substance use disorders (12). Studies of patients with chronic pain have produced mixed results (13, 14), with some evidence that alexithymia in this population is largely determined by the degree of comorbid anxiety and depression (14, 15).
As originally conceived by Barsky et al. (16), somatic amplification refers to a tendency in hypochondriacal patients to scrutinize their bodies for somatosensory input and then to amplify and misinterpret the sensation as representing a pathological process. The SSAS was designed and validated to measure this concept (17). Although somatic amplification has been used by cognitive theorists to conceptualize psychological factors in chronic pain (18), initial studies have not demonstrated elevated SSAS scores in chronic pain populations (14, 19).
The CDS was developed after clinical observations that a large subgroup of patients with chronic pain did not follow patterns of dependency, neediness, and depression frequently cited in the literature (2022). This subgroup also seemed not to score highly on more recently developed measures of alexithymia and somatic amplification (14). Instead, these patients seemed to minimize emotional distress, to describe idealized, shallow relationships with stereotypical roles, and to lead overly productive lives until the development of their pain syndrome. Initially, 20 scale items were created to capture these personality traits. Of the 20 items, five were selected on the basis of interitem reliability and correlation with chronic pain. These five items were then used in the present study and constitute the CDS.
On approval of our institutional review board, data from interviews and questionnaires were entered into a computer database for analysis using Statistica software (Statistica, Tulsa, OK). Between-group differences were assessed by unpaired t tests for parametric variables and by
2 analysis with the Yates correction for nonparametric variables. Interitem correlations were assessed by Pearson product moment correlation coefficients. Linear regression analyses were performed to ascertain the predictors of CDS scores.

2 = 7.6, df = 1, p < .01).
CDS scores had a normal distribution among the 150 subjects. Most items were significantly correlated with one another (Table 2 ). As outlined in Table 3 , item-to-scale correlations were all highly significant. Cronbachs
(0.57) was consistent with the low number of items on the scale.

The mean CDS score was 2.78 ± 0.80 for the chronic pain group and 2.03 ± 0.73 for the comparison group (t = 5.6, df = 148, p = .000). Table 4 outlines the social and demographic determinants of CDS scores. Among these variables, only a stable work history predicted CDS scores for subjects with chronic pain. However, this relationship no longer reached statistical significance when responses to item 3 were controlled for in analyses of covariance (F = 1.53, df = 97, p = .220).

| DISCUSSION |
|---|
|
|
|---|
There was considerable interest in and controversy surrounding personality characteristics of patients with chronic pain before the 1980s. Often it was assumed that pain fulfilled unconscious needs for guilt or masochism (20, 21) or served as a release for emotional pain (22). Indeed, some of the pain patients in our study group seemed to fit this profile. Unlike the counterdependent patients, they often sought excessive medical attention, exhibited emotional lability and hostility, and met criteria for a somatoform disorder.
The more rigorous studies examining personality traits of patients with chronic pain have focused on application of the MMPI and discovery of the so-called "Conversion V" MMPI profile, that is, elevation of the hypochondriasis and hysteria scales with a lesser elevation of the depression scale. This pattern has been able to differentiate chronic pain patients from patients having acute pain (23). Results of studies attempting to correlate the Conversion V profile with treatment outcomes have been mixed (24). This profile has been criticized in that the hypochondriasis and hysteria scales are largely somatic symptom checklists. There is also one study showing modest reductions in hypochondriasis and hysteria scale scores with improvement in pain, indicating that these scales may represent nonspecific symptoms associated with coping with a chronic illness instead of preexisting personality traits (25).
Because of these and other concerns about the validity and utility of the Conversion V profile, research into personality characteristics of patients with chronic pain, including counterdependency, diminished in the 1980s. Much of the focus of psychological research has shifted to behavioral and cognitive aspects of chronic pain, such as helplessness, pessimism, and catastrophic fears (26). Treatment approaches within this theoretical model have focused on relaxation and biofeedback techniques, decreasing reinforcement of pain behaviors, and promoting more positive cognitions (27).
It is possible that counterdependency promotes chronic pain through cognitive mechanisms. Because of their reliance on productivity and autonomy to support self-esteem, counterdependent patients may perceive a greater threat from a disabling pain syndrome, which, in turn, may enhance pain perception and promote chronicity (28). On the other hand, the answer may simply be that persons who work longer hours are more likely to get injured.
Research on counterdependency has been hampered by the lack of a scale or measure for this trait. The development of the CDS is the first step toward meeting this need. Future research should include the development of a more comprehensive scale that elaborates on each of the five dimensions of counterdependency to increase internal reliability. Potential overlap of counterdependency characteristics with obsessive-compulsive personality traits is another area of exploration.
