Factors explaining the intention to give blood among the general population.

BACKGROUND AND OBJECTIVES: The aim of this study was to identify factors explaining the intention to donate blood. MATERIALS AND METHODS: A random sample of 4000 respondents drawn from the general population received a questionnaire by mail. This questionnaire assessed variables as defined by the most prominent social cognitive theories. RESULTS: Overall, the respondents expressed a neutral mean level of intention to give blood in the next 6 months (2.84 on a five-point scale); 56.2% had never given blood in the past. The variables explaining 74% of the variance of intention were: perceived behavioural control (beta = 0.39; P < 0.001); factors facilitating taking action (beta = 0.25; P < 0.001); anticipated regret (beta = 0.16; P < 0.001); moral norm (beta = 0.11; P < 0.001); attitude (beta = 0.08; P < 0.01); level of education (beta = -0.03; P < 0.05); and past experience in giving blood (beta = 0.09; P < 0.001). Nonetheless, the predictive power of perceived behavioural control and moral norm was higher among the ever donors (both at P < 0.01) compared to the never donors, whereas the reverse was observed for attitude (P < 0.05). CONCLUSIONS: People's intentions are mainly determined by perceived barriers and obstacles regarding blood donations. This suggests that promotional strategies should focus on the elimination of barriers to action as well as the development of a higher perception of control. Also, messages should be adapted to the targeted population, based on their previous blood donation behaviour (i.e. never donors vs. ever donors).

Influence of a persuasive strategy on nursing students' beliefs and attitudes toward provision of care to people living with HIV/AIDS.

Based on the theory of planned behavior and the elaboration likelihood model, the aim of this study was to verify the effect of persuasive messages on nursing students' beliefs and attitudes regarding provision of care to people living with HIV/AIDS. The assumption was that a persuasive communication strategy induces a constructive change in beliefs and attitudes regarding provision of care. Baseline data collection was performed among a group of 74 nursing students (experimental group = 27; control group = 47). The questionnaire assessed the variables of the theory of planned behavior (i.e., beliefs, attitudes, perceived behavioral control). The results confirmed that persuasive messages generated a change in beliefs and attitudes of the nursing students concerning providing care to people living with HIV/AIDS. It appears that this strategy of modifying behavioral predispositions is effective and generates cognitive and affective changes. Therefore, educational programs should take these observations into consideration to ensure that future nurses are better prepared to provide appropriate care to people living with HIV/AIDS.

The attitude of Canadian nurses towards advance directives.

This article seeks to shed light on the beliefs that influence nurses' intention of respecting or not respecting an advance directive document, namely a living will or a durable power of attorney. Nurses' beliefs were measured using a 44-statement questionnaire. The sample was made up of 306 nurses working either in a long-term care centre or in a hospital centre offering general and specialized care in the province of Québec. The results indicate that nurses have a strong intention of complying with advance directives written by patients. The analysis also shows that four variables determine the strength of this intention: respect for autonomy; the location of the workplace; justice; and the dimension of relationships and emotions. Although these documents favour the expression of patients' wishes, nurses should be aware that they do not systematically guarantee respect of a patient's autonomy, nor do they replace a relationship based on trust between patients and health care professionals.

Comparison of patients' and health care professionals' attitudes towards advance directives.

OBJECTIVES: This study was designed to identify and compare the attitudes of patients and health care professionals towards advance directives. Advance directives promote recognition of the patient's autonomy, letting the individual exercise a certain measure of control over life-sustaining care and treatment in the eventuality of becoming incompetent. DESIGN: Attitudes to advance directives were evaluated using a 44-item self-reported questionnaire. It yields an overall score as well as five factor scores: autonomy, beneficence, justice, external norms, and the affective dimension. SETTING: Health care institutions in the province of Québec, Canada. SURVEY SAMPLE: The sampling consisted of 921 subjects: 123 patients, 167 physicians, 340 nurses and 291 administrators of health care institutions. RESULTS: Although the general attitude of each population was favourable to the expression of autonomy, multivariate analysis of variance (MANOVA) indicated that physicians attached less importance to this subscale than did other populations (p < .001). Above all, they favoured legal external norms and beneficence. Physicians and administrators also attached less importance to the affective dimension than did patients and nurses. Specifically, physicians' attitudes towards advance directives were shown to be less positive than patients' attitudes. CONCLUSION: More attention should be given to the importance of adequately informing patients about advance directives because they may not represent an adequate means for patients to assert their autonomy.
