Knowledge and attitude regarding organ donation among medical students in Hong Kong: a cross-sectional study.

OBJECTIVES: The rate of organ donation in Hong Kong is among the lowest in developed regions. Since medical students will play an important role in counselling patients for organ donation and identifying potential donors in the future, their knowledge, attitudes and action for organ donation are important. This study aims to understand knowledge, attitudes and actions with regard to organ donation among medical students and investigate the factors determining the knowledge and attitudes. DESIGN: A cross-sectional study. SETTING AND PARTICIPANTS: Medical students in Hong Kong were invited to complete a questionnaire. 377 medical students participated in the study. METHODS: The questionnaire assessed their attitudes, knowledge, action of organ donation, belief and perception on organ donation, and other factors. Linear regression analyses and logistic regression were performed to analyse the effect of the variables on knowledge, attitudes and action for organ donation. RESULTS: Almost all medical students (99.5%) held a positive attitude towards organ donation, but only 28.1% have signed up as organ donors. Determinants of knowledge of organ donation included belief in preservation of intact body after death (ß = -0.14, 95% CI = -0.24 to -0.04) and perceived confidence and competence of organ donation discussion (ß = -0.12, 95% CI = -0.22 to -0.02). Predictors of organ donor registration status included knowledge of organ donation (OR=1.03, 95% CI=1.00 to 1.06), perceived convenience of organ donation registration (OR=3.75, 95% CI=1.62 to 8.71), commitment to organ donation (OR=3.81, 95% CI=2.01 to 7.21) and exposure to organ donation (OR=4.28, 95% CI=2.37 to 7.74). CONCLUSIONS: Knowledge is positively associated with organ donation action. The above determinants of organ donation could be emphasised in medical education.

Is Positive Affect Related to Meaning in Life Differently in Younger and Older Adults? A Time Sampling Study.

OBJECTIVES: Prior studies have found that as people age, they value low-arousal positive affect (LAP) to a greater extent and high-arousal positive affect (HAP) to a lower extent. We aimed to investigate whether actually achieving those ideal affects was related to better well-being outcomes, measured in terms of meaning in life. METHODS: Using a time sampling design across 14 days (N = 162), we investigated whether the experience of LAP and HAP was related to the experience of meaning in life and how these associations differed across younger and older adults in Hong Kong. RESULTS: Both LAP and HAP contributed to the experience of meaning in life for both younger and older adults. The global effect of LAP on meaning in life was stronger for older than younger adults, whereas the momentary effect of HAP on meaning in life was stronger for younger adults than older adults. DISCUSSION: Findings suggest that achieving ideal affect is related to better eudaimonic well-being outcomes. People of different age groups know how they want to feel. Actually achieving the feelings endorsed by one's age group is associated with higher meaningfulness of life.

Contrasting the Effects of Mortality Salience and Future Time Limitation on Goal Prioritization in Older and Younger Adults.

OBJECTIVES: This study aims at contrasting the effects of limited future time perspective and mortality salience on goal prioritization across adulthood. Socioemotional selectivity theory (SST) argues that people increasingly prioritize emotionally meaningful goals when they perceive future time as more limited. Terror management theory (TMT) suggests that mortality salience (i.e., the awareness of one's mortality) drives people to prioritize the goal of perpetuating own existence through affirming cultural worldview. METHOD: In this study, participants (N = 438) were randomly assigned to six conditions that primed (a) limited future time, (b) mortality salience, (c) death reflection, (d) both limited future time and mortality salience, (e) both limited future time, and death reflection, or (f) none. RESULTS: Results showed that older adults allocated significantly more resources to emotionally close recipients who supported their cultural worldviews in conditions involving future time limitation and death reflection. They also allocated less resources to emotionally not close recipients who did not support their cultural worldviews in conditions involving future time limitation. Younger adults did not show these differences. Nor did mortality salience have any effect. DISCUSSION: These results suggest that future time perspective and death reflection shift age-related goals more than mortality salience.
