Somatization, somatosensory amplification, attribution styles and illness behaviour: A review

Somatic symptoms have been conceptualized in many different ways in literature. Current classifications mainly focus on the numbers of symptoms, with relative neglect of the underlying psychopathology. Researchers have emphasized the importance of a number of experiential, perceptual and cognitive-behavioural aspects of somatization. This review focuses on existing literature on the role of somatosensory amplification, attribution styles, and illness behaviour in somatization. Evidence suggests that somatosensory amplification is neither sensitive nor specific to somatizing states, and that other factors like anxiety, depression, neuroticism, alexithymia may also have an influence. Attribution research supports the existence of multiple causal attributions, which are related to the numbers of somatic symptoms. While somatizing patients have more organic attributions, depressed patients have more psychological attributions. A global somatic attribution style is associated with the number of obscure somatic symptoms, while a psychological attribution style is associated with both—psychological and somatic— symptoms of depression and anxiety. There are conflicting findings with respect to the role of normalizing attributions in reducing physician recognition of anxiety and depression. Specific symptom attributions appear to explain physician recognition of psychological distress, but global attribution styles do not appear to explain any further variance in physician recognition beyond that explained by specific causal attributions. Illness behaviour has been studied in two distinct ways in literature. Research focusing on attendance rates as a form of illness behaviour suggests that somatization is associated with high levels of health care utilization. There is also some evidence that health care utilization, amplification and attributions styles may be interrelated among somatizing patients. More structured ways to assess illness behaviour have found high levels of abnormal illness behaviour in this population. Overall, research appears to suggest a complex (and as yet unclear) relationship between somatic symptoms and underlying cognitions/illness behaviours. While it is clear that somatization is closely related to a number of perceptual and cognitive-behavioural factors, the precise nature of these relationships are yet to be elucidated.

Concerns, coping and quality of life in head and neck cancer patients.

This study was conducted to explore the concerns and coping mechanisms used by patients with head and neck cancer and assess their quality of life. A group of 50 consecutive patients with oral and laryngeal cancers were interviewed using a coping and concerns checklist and a semistructured interview proforma to elicit the common concerns in relation to head and neck cancers and their surgical treatment. The Hospital Anxiety and Depression Scale was used to detect anxiety and depression. Concerns were compared between oral and laryngeal cancers and between preoperative and postoperative patients. Commonest concerns were about the future (64%), subjective physical evaluation (60%), finances (56%), being upset (54%), communication (54%), current illness (52%) and inability to do things (50%). The commonest coping mechanisms used were helplessness and fatalism. Resolution was noted in less than 40% of the frequent concerns. As compared to laryngeal cancer patients, those with oral cancer significantly more often had concerns about current illness, subjective evaluation of health, eating and chewing, social interactions, pain and disfigurement (P<0.05). Most subjects had numerous unresolved concerns. Mainly ineffective coping mechanisms such as helplessness and fatalism were employed leading to incomplete resolution. Interventions to minimise these concerns and to handle associated anxiety and depression would improve their quality of life.

Controlled study of alexithymic characteristics in patients with psychogenic pain disorder.

Alexithymic characteristics were examined in a sample of 30 patients fulfilling the DSM-III criteria for psychogenic pain disorder using an interviewer-rated scale (Beth Israel Hospital Psychosomatic Questionnaire), a self-rated scale (Toronto Alexithymia Scale) and a projective technique (Thematic Apperception Test). The findings were compared with a control group of healthy subjects matched on sociodemographic variables. Pain patients were found to be more alexithymic in contrast to the control group as evidenced by the interviewer-rated and self-rated scales. The correlations among the three measures were in the expected direction.

Feasibility, Safety, and Efficacy of the Combination of D -Serine and Computerized Cognitive Retraining in Schizophrenia: An International Collaborative Pilot Study

The combination of pharmacotherapy and cognitive retraining (CRT) for the cognitive deficits of schizophrenia may be more efficacious than either approach alone, but this has not yet been tested. This study evaluated the feasibility, safety, tolerability, and efficacy of 12 weeks of D-serine, combined with CRT in the treatment of cognitive deficits in schizophrenia at two academic sites in parallel, in India and the United States. In a randomized, partial double-blind, placebo-controlled, parallel-group design, 104 schizophrenia subjects (US site=22, Indian site=82) were randomized to: (1) D-serine (30 mg/kg)+CRT (5 h/week), (2) D-serine+control CRT, (3) CRT+placebo D-serine, and (4) placebo+control CRT. Completion rates were 84 and 100% in the Indian and US samples, respectively. On various outcome measures of safety and tolerability, the interventions were well tolerated. D-Serine and CRT did not show any significant effect on the Global Cognitive Index, although both interventions showed differential site effects on individual test performance. CRT resulted in a significant improvement in Verbal Working Memory, and a trend toward improvement in Attention/Vigilance. This is the first study to demonstrating the feasibility, safety, and tolerability of combination pharmacotherapy and CRT in a multicenter international clinical trial. These preliminary findings provide support for future studies using higher doses of D-serine that have been shown to be efficacious or other pharmacotherapies, along with the newer cognitive remediation strategies that are individualized and that target basic information processing.

Sociocultural aspects of menstrual attitudes and premenstrual experiences in India

Menstrual attitudes were studied in a group of 48 Indian women using the Menstrual Attitude Questionnaire, modified and adapted for Indian background. Attitudinal factors of menstruation being a natural, bothersome and debilitating event were studied, as also denial of the event and healthy/unhealthy attitudes. High rating was seen in menstruation being perceived as a natural event and least as a debilitating one. Older women considered menstruation as a natural event. Relating premenstrual experiences to attitudes, it was observed that distressful symptoms correlated significantly with debilitating and unhealthy attitudes. Similarly, premenstrual well-being correlated highly with naturalness attitudes, thereby suggesting that the personal experiences are likely to influence the menstrual attitudes.

Persistent somatization in cancer : A controlled follow-up study

Nature and frequency of somatic complaints, severity of anxiety and depression, and nature of psychiatric symptoms and disorders were evaluated in 81 adequately treated cancer patients, disease-free or with residual disease, using a controlled, prospective follow-up design. Patients were included in the index group (n=60) if they had persistent somatic complaints or unexplained nature or severity of somatic complaints, or the control group (n=21), if they did not report somatic complaints. Instruments used for evaluation were the Scale for Assessment of Somatic Symptoms, Hospital Anxiety and Depression Scale, Psychiatric Assessment Schedule, and DSM-III-R. Common somatic complaints in the index group were pain (19%), fatigue (17%), sensory symptoms (30%), and mixed symptoms (27%). Subjects in the index group significantly (p<0.001) more often had depressive or anxiety disorder (19%) and atypical somatoform disorder (15%). Patients were treated appropriately with psychotropic medications and counseling. Follow-up at 4-6 months revealed a significant reduction in the number of somatic symptoms (p<0.001) and anxiety (p<0.001) and depression (p<0.05) scores. The observations confirm that somatic symptoms may persist in cancer patients, which are related to concomitant psychopathology, and require psychiatric intervention.

Somatization in cancer

Somatic symptoms can occur in disease-free cancer patients. The causes of such symptoms in cancer can be many and varied. These could be due to anxiety, depression, somatization or a manifestation of illness behaviour. Somatic symptoms can also arise out of treatments for the cancer like radiation treatment or chemotherapy. Cancer related somatic symptoms have cognitive, psychological, and physiological causes, each of which is amenable to treatment. The occurrence of somatoform disorders in cancer patients is likely to complicate the treatment and outcome of the cancer. Common somatic symptoms in cancer have been found to be pain, fatigue, anorexia, tiredness or exhaustion, weakness, reduced energy, lethargy, and tremors. Breathlessness, muscle pain, dizziness, and palpitation are common symptoms of anxiety and panic attack which have also been noted in cancer patients. Somatic concern and preoccupation are also common. These symptoms create difficulty in diagnosing depression and anxiety in cancer patients, and leads to the need for modification of the standard diagnostic criteria. Somatic symptoms in cancer respond to counselling and psychopharmacotherapy. More research are needed on this area to understand the process of somatization in a somatic disease.

Amplification and Attribution Styles in Somatoform and Depressive Disorders – A Study from Bangalore, India

Objective: The present investigation aimed to study attribution styles and somatosensory amplification among patients suffering from somatoform and depressive disorders. Methods: Two groups of 30 patients with diagnoses of somatoform disorder and depressive disorder, respectively (ICD-10 DCR), and one group of 30 normal controls were recruited. The study patients were assessed using the symptom interpretation questionnaire, somatosensory amplification scale, and scales for assessing alexithymia and illness attitudes. Results: The somatoform and depressive disorder patients had greater recent symptom experience than the normal group. The somatoform disorder group had higher somatic attribution scores, the depressive disorder sample had higher psychological attribution scores, and the normal group had higher normalizing attribution scores than the two other groups. Somatoform disorder patients had higher mean amplification scores than depressed patients, who in turn had higher scores than normals. Correlation analyses showed somatic attribution and certain illness attitudes to be closely associated in all three groups. Recent symptom experience was associated with amplification in the somatoform disorder group alone. Recent symptom experience, a diagnosis of somatoform disorder and lower normalizing attribution scores predicted amplification. Discussion: These findings indicate that somatoform and depressive disorder patients and normals differ from each other in their attribution styles. There is a clustering of attributes among somatoform disorder patients that include greater symptom experience, which is somatically attributed, and is associated with excessive illness worry, concern and preoccupation with bodily symptoms, and a fear of having or developing a disease. On the other hand, depressed patients and normal subjects who do have a somatic attribution style (though, as a group, they have lower somatic attribution scores than the somatoform disorder group), also harbor hypochondriacal beliefs and related attitudes.

Prevalence of chronic pain in psychiatric patients

&NA; Five hundred consecutive patients attending a psychiatric clinic were examined in order to ascertain the prevalence of chronic pain in various psychiatric illnesses and demographic categories. Chronic pain was found to be a frequent symptom in anxiety neurosis (60%), neurotic depression (45%) and hysteria (24.3%). Less than 3% of psychotic patients reported chronic pain. Females and those patients who had entered further education beyond secondary level were found to have significantly higher (P < 0.001) representation as compared to the psychiatric population without pain. The results are in accordance with certain earlier studies carried out almost two decades ago. Chronic pain was found to be a common symptom of psychiatric illness, reported by 18.6% patients, especially those diagnosed as having neurosis. It was also reported more often by females and by those with a higher education. The reasons for these observations require investigation.

Communication with relatives and collusion in palliative care: A cross-cultural perspective

Handling collusion among patients and family members is one of the biggest challenges that palliative care professionals face across cultures. Communication with patients and relatives can be complex particularly in filial cultures where families play an important role in illness management and treatment decision-making. Collusion comes in different forms and intensity and is often not absolute. Some illness-related issues may be discussed with the patient, whereas others are left unspoken. Particularly in palliative care, the transition from curative to palliative treatment and discussion of death and dying are often topics involving collusion. Communication patterns may also be influenced by age, gender, age, and family role. This paper outlines different types of collusion and how collusion manifests in Indian and Western cultures. In addition, promising avenues for future research are presented.
