Railway suicide: the psychological effects on drivers

People have jumped (or fallen) in front of trains on the London Underground system in increasing numbers throughout the twentieth century. During the past decade there have been about 100 such incidents each year, of which around 90 would involve the train driver witnessing his train strike the person on the track. Most are suicides or attempts at suicide. They represent major unexpected and violent events in the lives of the train drivers and it might be expected that some of them would respond by developing a post-traumatic stress reaction of the type identified by Horowitz (1976) or other adverse psychological reactions or both. The research reported in this paper was designed to characterize the range of responses of drivers to the experiences of killing or injuring members of the public during the course of their daily work. It was found that 16.3% of the drivers involved in incidents did develop post-traumatic stress disorder and that other diagnoses, e.g. depression and phobic states, were present in 39.5% of drivers when interviewed one month after the incident.

The psychosocial impact of HIV infection in women.

The aim of the investigation was to study the prevalence of current and past psychiatric morbidity and psychosocial problems in HIV seropositive (HIV +ve) asymptomatic women. A cross-sectional controlled study including 57 HIV +ve women belonging to CDC group II and III (43 intravenous drug users and 14 non-IVDUs heterosexuals) and 23 HIV -ve women (15 intravenous drug users and 8 non-IVDUs heterosexuals) is reported. Outcome measures included, past psychiatric history, current psychological status (Zung Anxiety and Depression scales, Symptom Check List 90-Revised), Social Supports and Locus of Control Scales, and information on changes in work, social and sexual life after HIV testing. Results showed that HIV +ve women differed very little from HIV -ve controls regarding outcome measures and indeed for some variables HIV infected women had lower levels of psychological morbidity. Multiple regression analyses showed that alcohol misuse and a predominantly external locus of control accounted for the 29% of the variance of psychiatric distress (F = 9.23, p < 0.0006). The implications of the findings are discussed.

Voluntary HIV testing in the antenatal clinic: differing uptake rates for individual counselling midwives.

This study looked at 12 midwives in the Riverside Health Authority who counselled parturient women about having the HIV antibody test. Results showed that the uptake rate of the test varied considerably across midwives (82% to 3%). Uptake rate varied, to some extent, by ethnic group of the midwife; Afro-Caribbeans having 36% uptake, others 11%. However, the wide variation within these groups suggests that ethnicity alone does not explain the difference in uptake rate. Factors which could be associated with uptake rate are the individual characteristics of both the midwife and of the antenatal clinic attender, such as age, ethnicity, knowledge of and attitudes to HIV and antibody testing, as well as the counselling approach of the individual midwife.

Sexual dysfunction in gay and bisexual men with HIV infection: evaluation, treatment and implications.

Sexual dysfunction problems are common in people with HIV infection, but their relevance has been recently highlighted in response to the increased survival shown by many individuals with HIV, and the publicity surrounding the development of new treatments for male sexual dysfunction. Thirty-four gay/bisexual men with HIV infection presenting with sexual dysfunction were assessed. Antiretroviral combination therapy including protease inhibitors was taken by 44%, other combinations not including protease inhibitors by 24%, while 32% were not taking any antiretrovirals. Primarily psychogenic sexual dysfunction was thought to be present in 44%, primarily organic dysfunction in 22% and a mixed aetiology in 34%. Treatments offered included psychological interventions and physical methods of treatment, alone or in combination. Treatment was effective, with 76% reporting resolution of the problems, 14% reporting improvement and only 10% reporting no change. Practical and ethical issues raised by the findings are discussed.

Prospective associations between lateralised brain function and immune status in HIV infection: Analysis of EEG, cognition and mood over 30 months

Prospective relations between individual differences in both lateralised neuro-psychophysiological functions and mood ratings with immune status (CD4 and CD8 counts) were examined in asymptomatic HIV-positive men (n = 27) over thirty months. They participated in a controlled study of zidovudine versus placebo (results published elsewhere). Measures included EEG spectra, neuropsychological tests and mood ratings. A model of reciprocal lateralised influences on the immune system was tested whereby patients with left superior to right hemispheric functions were predicted to show a less deleterious outcome than those with the opposite asymmetry pattern. Prospective relations with immune status were found in the EEG with lateralised theta, alpha and beta activity; among cognitive measures with word fluency, semantic processing, and lateralised motor and recognition memory (word/face) processes; with mood ratings including depression, confusion and the total mood score. The nature of the effects supported the laterality predictions. These unique data, showing that neuro-psychophysiological factors in HIV+ but otherwise healthy subjects predict immune competence and compromise present 2-3 years later, warrant replication in a larger cohort.

“I plan to have the HIV test”—predictors of testing intention in women attending a London antenatal clinic

In order to identify which factors predict a parturient womans intention to take up voluntary HIV testing in the antenatal clinic, 318 women were surveyed by anonymous self-completion questionnaire. The strongest predictors of intention to be tested were the perceived benefit of the test to the woman herself, her partner, and the midwife, perceived risk of HIV infection, younger age and being single and having a poor knowledge of the sexual routes of HIV transmission. Health education strategies should therefore concentrate on: (a) increasing the parturient womans knowledge of HIV transmission which will increase accuracy of perception of risk; and (b) stressing the potential benefits of HIV testing to all antenatal attenders, particularly to those who are older and in long term relationships.

The changing pattern of mental health problems in HIV infection: the view from London, UK.

As we end the second decade with AIDS, profound changes in our understanding of its aetiology, mechanism of disease and its treatment have led to significant improvements in survival, disease progression and quality of life for those individuals with HIV infection who are fortunate enough to have access to health care and to treatments for the infection and its complications. Unsurprisingly, the psychological and social consequences of HIV have also seen important shifts, giving rise to new and unforeseen difficulties, as well as a greater sense of hope. Here, some of the changes seen among people with HIV infection being looked after in a Central London teaching hospital and referred to the mental health services are reviewed and discussed.

A longitudinal study of the neuropsychiatric consequences of HIV-1 infection in gay men. II. Psychological and health status at baseline and at 12-month follow-up.

The aim of this study was to determine whether HIV infection is associated with increased psychosocial distress in the asymptomatic and early symptomatic stages of disease and to determine the factors associated with reporting health symptoms. Subjects included 61 gay men (41 HIV--, 20 HIV+) who were assessed at the time of requesting their first HIV test and again 12 months later. Measures included a detailed standardized psychiatric interview (Present State Examination, PSE), a range of psychosocial self-report measures and a physical symptom checklist. There were no differences between the HIV+ and HIV-- groups in terms of self-reported symptoms. Multiple regression analysis showed that the symptom reporting was not associated with clinical or immunological markers of disease progression but was associated with measures of psychosocial distress. Although both groups showed elevated levels of psychosocial distress at the time of HIV testing, there were no differences between serostatus groups at follow-up. Multiple regression analysis indicated that the best predictors of PSE scores at follow-up were baseline PSE score and a history of psychiatric illness. Early HIV disease is not associated with increased psychosocial distress and symptom reporting is more closely related to psychological measures than to clinical or immunological markers of disease.

Heterosexuals and HIV disease: A controlled investigation into the psychosocial factors associated with psychiatric morbidity

The aim of the study was to evaluate the prevalence of current and past psychiatric morbidity among HIV seropositive and HIV seronegative heterosexual men and women and to identify the psychosocial factors associated with psychiatric morbidity. Twenty-four asymptomatic HIV seropositive and twenty-six HIV seronegative heterosexuals were included in the study. Outcome measures included socio-demographic data, psychiatric history, current psychological status (Zung Self-Report Anxiety Scale, Zung Self-Report Depression Scale, Symptom Check List 90-R), Social Supports and Locus of Control Scales, and information on changes in work, social, and sexual life after HIV testing. There were no significant differences between HIV seropositive heterosexuals and HIV seronegative controls on any of the outcome measures. Levels of psychiatric morbidity were generally low and similar to those expected in a general out-patient medical population. Multiple regression analyses showed that degree of social support was the only significant factor associated with psychiatric morbidity. The implications of the findings are discussed.

Health-related quality of life in HIV infection

The need for the quantitative assessment of health-related quality of life is increasingly being recognized in many different areas of health care, particularly in the evaluation of new treatments. This paper addresses the relevance of quality of life evaluation to HIV disease. The first part of the paper discusses the different ways in which quality of life has been defined and considers a number of methodological problems and different theoretical approaches to its measurement. The second part of the paper reviews the existing work on the quantitative evaluation of quality of life in HIV disease, including both descriptive studies and treatment evaluation studies. It is argued that the evaluation of health-related quality of life is important in HIV infection and should become an integral part of future treatment evaluation studies in order to help both clinicians and patients in their decisions concerning available treatment options.
