Health care workers and HIV/AIDS: a critical review of the literature.

This paper reviews the extensive literature which looks at the impact of HIV/AIDS on health care workers (HCWs). The knowledge and attitudes of HCWs toward people with HIV/AIDS and other relevant attitudes, for example those regarding male homosexuality have been widely studied whereas attitudes to intravenous drug use are perhaps under-investigated. Three major themes of the literature are examined. These are fear of infection, beliefs about the right to refuse care and the stresses associated with caring for HIV positive people. A number of educational interventions which attempt to change HCWs attitudes and beliefs are reviewed. Some notable gaps in the literature are identified. Neglected areas include attitudes to women, people of colour and consideration of the organizational and societal factors mediating the impact of HIV upon healthcare workers. Limitations of the research techniques used are identified and future implications for health care workers are considered.

Modelling and modifying young heterosexuals' HIV-preventive behaviour; a review of theories, findings and educational implications.

Studies applying social cognitive frameworks such as the health belief model and the theory of reasoned action to HIV-prevention are reviewed. These models suggest that appropriate beliefs, attitudes, social norms, intentions and perceived self-efficacy are sufficient psychological conditions for safer sexual behaviour. Limitations inherent in these accounts are identified and additional factors which need to be incorporated in psychological models and health education programmes are highlighted. These include, the motivational complexity of sexual behaviour, the emotional and arousal states in which it is enacted, the difficulties of planning what is regarded as spontaneous interaction and contextual factors which can undermine HIV-preventive intentions. Health education interventions aimed at individual, group and community levels are examined in light of this theoretical review and action-focused, empowering interventions grounded in youth culture are recommended.

Measurement of condom use in 72 studies of HIV-preventive behaviour: a critical review.

Ninety-four distinct measures of condom use were identified in a review of 72 psychosocial studies of HIV-prevention. A coding scheme was developed which characterised each measure in terms of: (1) type of measure (e.g. frequency of use, use at last intercourse), (2) response alternatives (e.g. Likert scale), (3) recall period (e.g. lifetime, last month), (4) partner specification (e.g. 'new' partner), and (5) activity specification (e.g. vaginal or anal intercourse). Results show a great deal of inconsistency in measurements of condom use across studies. Single-item frequency or consistency measures were most common. Several difficulties with measures employed to date were identified. These included indeterminate reliability and validity of measures, lack of attention to the epidemiological significance of different types of use and terminological and self-presentational problems with items assessing use. Implications of extant measurement approaches for the accumulated knowledge base on predictors of 'safer' sex and suggestions for future research in this area are outlined.

Invasive Haemophilus influenzae infections in older children and adults in Seattle.

We recently saw two unusual manifestations of Haemophilus influenzae infection in adults in the Seattle area: fulminant sepsis in an otherwise-healthy man and three episodes of bacteremia in a woman with chronic liver disease. We retrospectively identified 79 bacteremic and 40 non-bacteremic cases of invasive H. influenzae infection developing in patients > or = 9 years of age between 1 January 1980 and 31 December 1990. The most common clinical presentations among patients with bacteremia included pneumonia (52%), septicemia (27%), meningitis (8%), gynecologic infection (5%), and epiglottitis (5%). Underlying illnesses were common in these patients, and overall mortality was 35.5%. Factors associated with mortality included underlying neurological disease, polymicrobial bacteremia, and advanced age. The clinical presentations of the 40 patients without bacteremia included soft-tissue abscesses (45%), lung abscesses (18%), peritonitis (13%), meningitis (8%), gynecologic infection (8%), epididymitis (5%), mastoiditis (3%), and osteomyelitis (3%). Thus H. influenzae disease has a variety of presentations and is associated with significant mortality in older children and adults. Further study is required to determine whether widespread administration of H. influenzae type b conjugate vaccine to infants will alter the development of subsequent disease in later life.

In search of a psychology of safer-sex promotion; beyond beliefs and texts.

Belief and attitudinal change are important to the promotion of safer sexual behaviour. However, the individual decision-making psychology implicit in belief-change models provides only a partial picture of the determinants of sexual behaviour. A broader psychological understanding emphasizing the complex social skills involved in regulating sexual interaction is advocated. A discourse analysis critique of the viability of characterizing individuals' psychology on the basis of verbal responses is discussed and it is noted that psychological models linking such responses to underlying beliefs and cognitions must be based on measures which accurately predict health behaviour. It is concluded that an interactive model incorporating personal, interpersonal and situational constraints on sexual behaviour could be used to design effective programmes addressing barriers to HIV protection. Such interventions would promote communication and sexual negotiating skills and could be included in school curricula. This would have radical implications for sex education, shifting its theoretical basis from biology to social psychology and its methods from information-giving to participation and practice.

Health beliefs and promotion of HIV-preventive intentions among teenagers: a Scottish perspective.

Beliefs concerning the spread of the human immunodeficiency virus (HIV) and preventive behaviors were examined in a sample of 351 sexually active Scottish teenagers. A postal questionnaire, including measures of variables specified by the health belief model (HBM) and preventive intentions, was employed. The relation between HBM measures and reported endorsement of HIV-preventive intentions was investigated. Results indicated that, in general, respondents intended to use condoms with new sexual partners. The majority also intended to carry condoms if they thought they might have sex with a new partner and to ask potential partners about their previous sexual history. Multiple-regression analyses showed that measures of health beliefs, gender, age, sexual experience, and previous condom use accounted for 17.8% to 24.3% of the variance in reported preventive intentions. Perceived barriers to preventive behaviors were found to be important predictors. However, the overall pattern of results raised questions concerning the adequacy of the HBM as a model of the determinants of HIV-preventive intentions, and the need for an extended model is discussed. Separate analyses were conducted for men and women and for 16- and 18-year-olds, and the implications for modeling intention formation in these subgroups are considered. The relevance of these findings to HIV-preventive campaigns is also discussed.

Context and content: the impact of school-leaving and school-based health education on AIDS-relevant cognitions.

A survey examined health beliefs and intentions among 690 16-18 year-olds in Dundee. Respondents in the younger cohort (n = 363) were classified according to their educational situation (at school vs left) and self-reports of having received AIDS/HIV-relevant health education. Both remaining in school and receiving AIDS/HIV-relevant health education had independent beneficial effects, but the effects of leaving school also interacted with sex of respondent and with amount of relevant education received prior to leaving. Males' and females' reliance on mass media and other information sources diverged once they left school, indicating that males who leave school early are most likely to disregard useful or important information regarding AIDS. Consistent with this finding, leaving school reduced the difference between males' and females' intention to use condoms with a new partner. The beneficial impact of having previously received AIDS/HIV-relevant education on beliefs concerning the controllability of the epidemic and on feeling worried about everyday contact with a person with HIV/AIDS, was most marked among those who had left school. The results are discussed in terms of their implications for health education strategies.

Young people learning about AIDS: a study of beliefs and information sources.

A study of the views of Scottish teenagers and undergraduates on health education issues relevant to human immunodeficiency virus (HIV) spread is reported. A sample of 1008 young people (690 teenagers and 318 students) returned a postal questionnaire designed to measure a range of relevant cognitions. These included levels of concern, perceived knowledge, perceived vulnerability, perceived seriousness, recall of health education campaigns, preferred information sources and views on the discussion of HIV/AIDS with significant others. Low levels of perceived vulnerability, high levels of recall for national campaigns, and discrepancies between used and credible sources of information are reported. Cohort and gender differences and correspondences with American and Australian studies are discussed. The implications of these findings for future AIDS education campaigns are also considered.

Social judgements of sex and blame in the context of AIDS: gender and linguistic frame.

A questionnaire study (N = 318) examined social judgements of sexually active males and females on positive and negative evaluative dimensions, as a function of the perceiver's gender, and the linguistic frame of judgement. This frame was manipulated by requiring respondents to rate themselves on a number of descriptive dimensions which evaluatively favoured either a 'liberal' or a 'conservative' approach to sex and personal relationships, before making their judgements. Female targets were rated more negatively than males on both evaluative dimensions. There were also significant interactions between the framing manipulation and both subject and target gender for the evaluatively positive measure. There was some evidence of females being perceived more positively in the liberal than the conservative frame and within the conservative frame they were judged less positively than male targets. Male subjects tended to rate targets more positively in the liberal frame whereas females did not. Judgements of blame and personal responsibility in the context of AIDS were examined as a function of the independent variables and also revealed gender differences. These factors, and particularly the importance of language in framing the context of self-perception and social judgement, are discussed.

Religiosity and adolescents' premarital sexual attitudes and behaviour: an empirical study of conceptual issues.

A review of the literature concerning the relationship between religiosity and premarital sexual attitudes and behavior revealed inconsistencies in research findings and problems with methodology and operationalization of variables. A postal questionnaire to 527 16-18 year olds examined the associations between 6 models of religiosity (religious upbringing, denominational affiliation, ritual/behavioral, self-attitude/self-schema, and salience of religious identity) and personal sexual standards, attitudes towards sexually active others, virginal status, anticipation of sexual intercourse, and frequency of both coitus and noncoital sexual experiences over the previous year. A negative relationship between religiosity and a number of sexual attitudes and behaviors was observed, though nonsignificant relationships in the case of sexual experiences without intercourse suggested the maintenance of a technical virginity to accord with religious precepts. There was also some evidence that Catholic adolescents were more likely to be sexually active than non-Catholics when current religiosity was controlled for. The results lent strongest support to models which implicated self-conception either in terms of self-attitudes/self-schemas or the salience of religious identity. Implications of the study and suggestions for future research are outlined.
