Is there an independent somatic symptom dimension in older people?

OBJECTIVE: In explaining the dimensions underlying nonpsychotic symptom reporting, traditional psychiatric paradigm has advocated a hierarchical model in which somatic symptoms are subsumed within two correlated psychological dimensions. A more recent alternate view is that somatic symptoms may be clearly separated from typical anxiety and depression symptoms if somatic symptoms are adequately recorded. The main aim of this study is to determine whether discrete somatic dimension(s) could be derived in older people. METHOD: Exploratory factor analysis was used to determine the factor structure underlying the responses of 10662 ambulatory primary care patients, aged 60 years and over, who completed the 34-item SPHERE (Somatic and Psychological HEalth REport) questionnaire of somatic and psychological symptoms. In addition, weighted factor scores were compared according to whether there was a physical or psychological reason for presentation to a doctor. RESULTS: A clinically interpretable four-factor solution, consisting of mood, cognitive, musculoskeletal, and fatigue symptoms, was derived. When factor analysis was repeated by gender, the only difference was that mood, cognitive, and pain-fatigue factors were derived in males. In the overall sample, all factor scores were higher in patients with a purely psychological reason for presentation. CONCLUSION: Somatic symptoms could be measured independently of psychological symptoms in the current sample of older primary care patients.

The neglect of somatoform disorders by old age psychiatry: some explanations and suggestions for future research.

AIM: The somatoform disorders have long been ignored by old age psychiatry. The main aim of this paper is to identify and examine possible reasons for this neglect. METHOD: A selective review of the general literature on somatoform disorders. RESULTS: Significant conceptual, diagnostic and classificatory problems have impeded the consideration of somatoform disorders in older people. There is a perception that somatoform disorders are infrequent and have not been validated as independent clinical disorders. However, we present evidence that the more broadly defined somatoform disorders are common in all age groups in primary care and meet criteria for the determination of clinical validity. General difficulties in the assessment of psychiatric disorders in primary care, the setting in which somatoform disorders are most common, are compounded by a lack of support from old age psychiatry services. Effective psychological therapies may not be readily available to sufferers. CONCLUSION: There is a need for change in the conceptualisation and nosology of the somatoform disorders. The formulation of age appropriate diagnostic criteria and presentations is a prerequisite for determining the clinical validity of these disorders in older people. This can be followed by study of their frequency, associated risk factors and treatment. A system of education that enhances the management of these disorders within primary care and old age psychiatry services is needed.

Separation anxiety in the elderly.

Separation anxiety has been studied in children and young adults but little is known about this form of anxiety in older people. This study aimed to examine socio-demographic, psychological and physical health correlates of separation anxiety in the elderly. Eighty-six ambulatory subjects aged 62-87 years were recruited from primary medical care practices to participate in this study. The presence of lifetime DSM-IV affective and anxiety disorders was determined by structured clinical interview. Subjects also completed a battery of self-report questionnaires measuring levels of state and trait anxiety, juvenile and adult separation anxiety. Adult separation anxiety scores were moderately correlated with juvenile separation anxiety scores (r= .52, P < .001), trait anxiety (r = .55, P < .001) and state anxiety scores (r = .66, P < .001), as well as younger age (r = .39, P < .001). Higher adult separation anxiety scores were also associated with a lifetime history of any anxiety disorder (t = 3.74, df = 84, P < .001) or any affective disorder (t = 2.12, df = 84, P < .05). However, adult separation anxiety was not associated with increasing age, being widowed, living alone or poorer physical health. Clinicians working with the elderly need to routinely explore this form of anxiety as it may complicate the pattern of presentation of other anxiety and affective disorders, and require specific forms of intervention.
