The Illness Attitudes Scale (IAS) is a self-report instrument comprising nine subscales designed to assess fears, beliefs and attitudes associated with hypochondriasis and abnormal illness behaviour [Kellner (1986). Somatization and hypochondriasis. New York: Praeger.]. The purpose of the present study was to explore the factor structure of the IAS in a chronic pain sample as a preliminary step toward determining the use of this measure in this sample. Hypochondriacal tendencies have been postulated to play a role in maintaining and exacerbating responses to chronic pain and, therefore, appropriate measurement in this sample is important. In the present study, consecutive chronic pain patients presenting to a pain treatment program (N = 198) were administered the IAS. Principal component analysis with oblique (Oblimin) rotation identified that five factors best explain the measure in this population. These factors were (1) fear of illness, (2) effects of symptoms, (3) health habits, (4) disease phobia and conviction and (5) fear of death. The factor structure overlapped to some degree with the scoring of the IAS proposed by Kellner (1986), as well as with the factor structure identified in a non-clinical sample [Ferguson, E. & Daniel, E. (1995). The Illness Attitudes Scale (IAS): a psychometric evaluation on a non-clinical population. Personality and Individual Differences, 18, 463-469.]. There were enough discrepancies, however, to suggest an alternative method for scoring the IAS with chronic pain patients. Implications for the use of the measure with chronic pain patients, as well as future research directions for exploring the utility of this measure with chronic pain patients, are discussed.

Recent recommendations regard musculoskeletal disorders of the masticatory system as dual-axis disorders, but little comparative data of psychologic factors across different pain populations are available. In this study, presenting psychologic profiles were assessed in 40 Australian and 42 Finnish patients diagnosed with temporomandibular disorders. Findings were compared with those of a group of Australian patients reporting acute dental pain and with reference to response to conservative management. The psychologic testing instrument incorporated cognitive, motivational/affective, and illness behavior variables, and it was based on validated general pain questionnaires (Coping Strategies Questionnaire and Illness Behavior Questionnaire). This instrument was found internally reliable in the majority of its subscales in the group studies and provided comparable data to other pain populations. Significant differences in the presenting psychologic profiles were found according to nationality, type of pain suffered, and treatment outcome. Affective disturbance, hypochondriasis, lack of cognitive control, and feeling ill with symptoms were identified in discriminant function analysis as potential predictors of treatment outcome, and they correctly classified 79% of the Australian and 87% of the Finnish patients with temporomandibular disorders. It was concluded that psychologic profiles differed in the two nationalities and were related to treatment outcome. The concept of multiaxial assessment was supported.

The Illness Attitudes Scale (IAS) assesses fears, beliefs and attitudes associated with hypochondriasis [Kellner, R. (1986). Somatization and hypochondriasis. New York: Praeger Publishers.]. Recent factor analytic investigations of the IAS in non-clinical samples have suggested a number of different factor solutions. In study 1, we used principal components analysis with both orthogonal and oblique rotation to better explore the structure of this measure. Using a random selection of 390 participants from a larger pool of 780, a five-factor solution was identified: (1) fear of illness, death, disease and pain, (2) effects of symptoms, (3) treatment experiences, (4) disease conviction and (5) health habits. In study 2, confirmatory factor analysis (CFA) of responses from the remaining 390 students evaluated: (a) a single-factor model, (b) Kellner's original nine-factor model, (c) a four-factor model proposed by Ferguson and Daniel [Ferguson, E. & Daniel, E. (1995). The Illness Attitudes Scale (IAS): a psychometric evaluation on a nonclinical population. Personality and Individual Differences, 18, 463-469.], (d) a different four-factor model proposed by Stewart and Watt [Stewart, S. H. & Watt, M. C. (1998). A psychometric investigation of the Illness Attitudes Scale (IAS) in a nonclinical young adult sample. Submitted for publication.] and (e) the five-factor model derived in study 1. Of these models, greatest support was obtained for our five-factor model. However, it was also clear that this model could be improved. Based on the results of the CFA, as well as previous research and theoretical considerations, we tested a revised model in which the health habits factor was deleted. Analysis of the revised model showed that it received the greatest support and could be conceptualized as either four distinct factors or as hierarchical in nature, with four lower-order factors loading on a single higher-order factor. Future directions for research as well as suggestions for scoring and using the IAS with nonclinical samples are discussed.

The utility of DSM-IV criteria for pain disorder was investigated within a consecutive sample of 90 chronic pain patients aged between 18 and 65 years. In this sample, 65.6% (n = 59) fulfilled diagnostic criteria for DSM-IV pain disorder. Of the patients with DSM-IV pain disorder, 22% fulfilled additional criteria for depressive disorder, 6.8% for hypochondriasis, and 23.7% for any other DSM-IV diagnosis. Only 54.2% of the patients with DSM-IV pain disorder had no comorbid psychiatric disorder. When assessing somatoform symptoms without hierarchical guidelines, there is a great overlap between the symptomatology of pain disorder and other somatoform disorders. Of 59 patients with DSM-IV pain disorder, 93.2% also met criteria for DSM-IV undifferentiated somatoform disorder and 10.2% for DSM-IV somatization disorder. The mean number of somatoform symptoms was 17 in the total sample. Despite the presence or absence of a general medical condition, there was no significant difference between pain disorder associated with both psychological factors and a general medical condition (code 307.89) and pain disorder associated with psychological factors (code 307.80) with regard to the pain duration, intensity, and type and the level of disability and educational level. The formulation of a distinct psychiatric entity for pain conditions may improve the consideration of psychosocial factors in the pathogenesis and clinical cause of pain. However, with regard to our data, the distinctive validity of different subtypes of pain disorder as provided by DSM-IV awaits further clarification.

This study evaluates the classification of pain from the perspective of the DSM-IV system. Of 60 in-patients with long-standing and disabling pain syndromes, 29 with pain disorder (PD) and 31 with pain as part of a multiple somatization syndrome (MSS) were compared before and after a structured cognitive-behavioral treatment. It was hypothesized that MSS patients show more psychological distress, are more severely disabled, and respond less to the treatment. Both groups were similar with respect to sociodemographic status, history of pain symptomatology and comorbidity with DSM-IV mental disorders. The results show that MSS patients had higher levels of affective and sensoric pain sensations as well as more pain-related disabilities. They were also less successful during treatment to reduce their pain-related depression and anxiety. Psychosocial functioning was improved only by PD patients, but remained almost unchanged in the MSS group. However, there were no group differences concerning general depression and hypochondriasis, dysfunctional attitudes towards body and health, and use of pain coping strategies. It is concluded that the DSM-IV distinction between 'pure' pain disorder and syndromes involving pain plus multiple somatoform symptoms cannot generally be confirmed, but further studies of validation are needed.

Movement disorders have rarely been the result of psychiatric disturbances. Psychogenic dystonia is caracterized by inconsistent findings, a known precipitant factor, onset in legs, pain, multiple somatizations and incongruent association with other movement disorders. We report two patients with clinically established psychogenic dystonia. Patient 1: a female that presented sudden loss of strength in her four limbs; she developed feet dystonia, alternant laterocollis, generalized and irregular tremor, and limb hypertonia that disappeared with distraction; psychological examination showed severe depression, hypochondria and obsessive disorder. Patient 2: a female that presented with irregular limb tremors that disappeared with distraction and left foot dystonia nine years ago; she gradually lost her walk capacity; she complained pain in lumbar area and in her left limb, psychological examination showed infantile behaviour, low frustration tolerance, impulsivity and self-aggression. Their complementary exams showed no alterations and they had no response to specific pharmacological treatment. Dystonia is rarely psychogenic, but this etiology is suggested when clinical characteristics are inconsistent and incongrous with a classical disorder. It should be part of differential diagnosis when appears in association with other somatization or psychiatric disorders.

Personality characteristics and disorders have long been noted in the chronic pain population. Clinicians and researchers alike will attest to the high rates of personality difficulties encountered in these individuals. Historically, it has been found that certain personality styles such as hypochondriasis and hysteria are common in chronic pain suffers. In addition, the prevalence of personality disorders (PDs) is significantly greater in the pain population than in the general population or in medical or psychiatric populations. A diathesis-stress model has been suggested to account for this finding and is discussed in this article, with implications for both treatment and research.

The authors studied interventions recommended by consultation-liaison (C-L) psychiatrists when they diagnosed somatoform disorder prospectively in a cohort of 4,401 consecutive inpatients referred to the C-L psychiatry service of a general teaching hospital, using standardized MICRO-CARES methodology. A DSM-III-R somatoform disorder was diagnosed in 2.9%, somatoform pain disorder in 1.4%, conversion disorder in 0.7%, hypochondriasis or somatization disorder undifferentiated/not otherwise specified in 0.6%, and somatization disorder in 0.2%. In 3.4%, somatoform disorder was considered a differential diagnosis. Psychiatric comorbidity included mood disorder (39%), personality disorder (37%), and psychoactive substance use disorder (19%). Recommendations were made about antidepressants in 40% of the patients, anxiolytics in 18%, sedatives in 18%, and antipsychotics in 10%. Psychiatrists recommended the following: more laboratory tests for 14%; additional medical/surgical consultations for 11%; an increase in the vigor of medical treatment for 13%; and psychological treatment for 76%; also they stressed an earlier discharge of 16%. Psychiatrists were more likely to request a prolongation of inpatient stay for patients with comorbid somatoform, mood, anxiety, and personality disorder. Differences in characteristics and treatment of the subgroups tended to be consistent with their constructs and comorbid psychiatric diagnoses.

DIFFICULT DIAGNOSIS: Depression in the elderly can take on many often misleading aspects. Sadness may be considered legitimate or "normal" for an elderly person. Depression may masquerade as an organic disorder where somatic complaints, pain and anxiety predominate. All these different clinical forms may mislead the clinician. THE MASK OF HYPOCHONDRIA: A tendency to hypochondria, found in more than one-half of all depressed elderly subjects, may be reinforced by bouts of complementary examinations. The patient is convinced of having an unrecognized organic disease. The mask of hypochondria must be considered with special care because it is a major risk factor for attempted and successful suicide. THE MASK OF DELUSIONS: Elderly patients often develop a state of melancolia-like depression with delusions. Delusions may be congruent with the predominant depressed mood, for example a guilt feeling for an act never committed, or inversely, non-congruent with the thymic state (persecution, negation delusin), for example Cotard syndrome where the patient is persuaded that his/her organs are malfunctioning or have disappeared. Despite these impressive mood disorders that often incite prescription of a neuroleptic, these elderly patients respond favorably to antidepressor treatment.

The Fitz-Hugh-Curtis syndrome is a peri-hepatitis following a genital infection. It usually occurs in young women. Chlamydia trachomatis is the most frequent causal agent. Clinical signs include acute or recurrent pain in the right hypochondria. Liver tests are not modified and the sonographic examination is normal. Diagnosis can be suspected on the basis of serology, and formally established by laparoscopy showing violin string-like adhesions. Prolonged antibiotic treatment is effective.
