The Relationship Between Big Five Personality Traits and Sleep Patterns: A Systematic Review.

Sleep, an intrinsic aspect of human life, is experienced by individuals differently which may be influenced by personality traits and characteristics. Exploring how these traits influence behaviors and sleep routines could be used to inform more personalized and effective interventions to promote better sleep. Our objective was to summarize the existing literature on the relationship between personality traits and sleep patterns through a systematic review. An abstract and keyword search was conducted in PsycINFO, Cochrane and PubMed, collecting relevant literature, published between January 1980 and June 2024. A total of 1713 records were found, of which 18 studies were analyzed in the descriptive synthesis. Relevant studies covered populations in 11 different countries, Australia, China, Estonia, Finland, Germany, Italy, Japan, Poland, Turkey, the United Kingdom, and the United States, comprising a total of 58,812 subjects. All studies reported an association between a sleep pattern with at least one of the Big Five personality traits (agreeableness, conscientiousness, extraversion, neuroticism, openness to experience). Ten studies found associations between personality and sleep quality, all of which reported a link between neuroticism and sleep quality (effect sizes 0.183-0.40). Five studies found an association between conscientiousness and morningness (effect sizes 0.16-0.35). Other sleep patterns linked to personality traits included sleep duration, nightmare frequency and distress, sleep deficiency, sleep continuity, insomnia severity and sleep problems, sleep hygiene, sleep latency and daytime sleepiness. This novel systematic review confirms that sleep and personality traits are related, suggesting that those traits should be considered when trying to understand or change one's sleep behavior.

What are effective approaches to increasing rates of organ donor registration among ethnic minority populations: a systematic review.

OBJECTIVES: To identify effective interventions to increase organ donor registration and improve knowledge about organ donation among ethnic minorities in North America and the UK. DESIGN: Systematic review. DATA SOURCES: MEDLINE, EMBASE, PsycINFO, CINAHL and Cochrane Central searched up to November 2012, together with four trials databases and the grey literature. REVIEW METHODS: A systematic search followed by assessment of eligibility and quality. An interpretive and thematic approach to synthesis was undertaken. This examined the nature and delivery of interventions in relation to a range of outcomes: verified registration, changing knowledge and a measured shift towards greater readiness. RESULTS: 18 studies were included in the review, comprising educational and mass media interventions. Mass media interventions alone reported no significant change in the intention or willingness to register. Educational interventions either alone or combined with mass media approaches were more effective in increasing registration rates, with a strong interpersonal component and an immediate opportunity to register identified as important characteristics in successful change. CONCLUSIONS: Effective interventions need to be matched to the populations' stage of readiness to register. Measured outcomes should include registration and shifts along the pathway towards this behavioural outcome.

'Having a different conversation around death': diverse hospital chaplains' views on end-of-life care.

OBJECTIVES: Hospital chaplaincy in the UK's National Health Service (NHS) is an allied profession that is emerging from its origins as an aspect of Anglican clerical organisation. This paper describes the perceptions and practices of hospital chaplains around end of life care and organ donation. DESIGN: Qualitative study involving 19 semi-structured exploratory interviews with hospital chaplains in five NHS Hospital Trusts across two regions in the UK. RESULTS: Chaplains provided generic support for the family around death and in relation to end of life conversations. While chaplains were supportive of efforts to increase awareness of issues around deceased donation they held a range of views on organ donation and had limited knowledge of hospital processes and practices. CONCLUSIONS: There is scope for greater training and involvement of hospital chaplains in hospital work on organ donation, and in developing new forms of community engagement to promote awareness and debate.

Attitudes to deceased organ donation and registration as a donor among minority ethnic groups in North America and the U.K.: a synthesis of quantitative and qualitative research.

OBJECTIVES: A systematic review and synthesis of quantitative and qualitative research were undertaken to examine attitudes to deceased donation and registration as an organ donor among ethnic minorities in the U.K. and North America. DESIGN: A systematic search and assessments of relevance and quality were conducted. Parallel syntheses were then undertaken of 14 quantitative and 12 qualitative papers followed by their integration. The synthesis was organised around five barriers that emerged as key issues: (1) knowledge regarding deceased donation and registration as a donor; (2) discussion of donation/registration with family members; (3) faith and cultural beliefs; (4) bodily concerns including disfigurement and intactness; and (5) trust in doctors and the health care system. RESULTS: In all countries, knowledge of organ donation and registration remained low despite public campaigns, with African-Americans and Black African and Black Caribbean populations in the U.K. often regarding organ donation as a 'white' issue. Each of the four attitudinal barriers was also more prevalent among ethnic minorities compared with the majority population. However, the significance of trust and uncertainties regarding religion/faith differed between groups, reflecting salient aspects of ethnic identity and experiences. Differences were also identified within ethnic groups associated with age and generation, although respect for the views of elders often influenced younger peoples' willingness to donate. CONCLUSION: There is a need for a more nuanced understanding of ethnicity and of variations in attitudes associated with country of origin, age/generation, socio-economic status and area of residence, to inform public campaigns and promote sensitive discussions with bereaved ethnic minority families. The traditional focus on knowledge and attitudes also requires to be complemented by a greater emphasis on organisational and service-related barriers and changes required to enhance ethnic minorities' access to registration as a donor and consent to deceased donation.
