The development of project managers and leadership has been highlighted as crucial for improving project success and performance, resulting in a rise of interest in project leadership research over the last two decades. While several qualitative reviews have been conducted, there have been limited quantitative and systematic reviews on project leadership. This study fills this gap by portraying the knowledge landscape and tracking the evolution of project leadership research from 1998 to 2022 through bibliometric approaches.

Based on 816 records, including 793 articles extracted and selected from the Web of Science database and specific journals, and 23 articles selected from three non-SCI/SSCI indexed journals, the authors used CiteSpace and bibliometrix R-package to depict visualizations of the trajectory of co-cited references, the landscape of co-occurred keywords and emerging trends in project leadership via reference co-citation analysis, keyword co-occurrence analysis and thematic mapping.

The bibliometric analyses enabled the authors to understand the conceptual aspects of project leadership and its theoretical background. Three stages of the intellectual bases were identified and tracked: the infancy phase (1998–2007), the growth phase (2008–2014) and the new development phase (2015–2022). The results of keyword co-occurrence analysis indicated that the research focus evolved from investigating traits and competences to examining the effects of traditional leadership behaviors, and then considering context-specific leadership. The findings of thematic mapping and theoretical interpretation illustrate the potential directions of the competence comparison, new and appropriate leadership, and the interaction between leadership and context.

This study advanced the field by providing a systematic review of project leadership, developing potential future directions for project leadership research and providing practical implications for career development and training.

This paper aims to report the findings of a survey study exploring perceptions about cognitive impairment. These findings are relevant to public health campaigns and education programmes.

A survey exploring respondents’ views and knowledge about mild cognitive impairment (MCI) was circulated via UK networks. A total of 417 respondents completed the survey, including people living with cognitive impairment (n = 10), care partners (n = 23), older adults (n = 83), younger adults (n = 83), general health-care professionals (n = 96), dementia specialist health-care professionals (n = 48) and dementia specialists (n = 40).

Respondents were more confident in their knowledge about dementia than cognitive impairment but wanted more information about both conditions. Younger adults were uncertain about many aspects of MCI, and were the most likely to view MCI as a normal part of ageing. Diet (45.1%, n = 188) and personal behaviour (63.8%, n = 266) were the least endorsed possible causes of MCI, suggesting a lack of awareness of lifestyle choices as risk factors for MCI.

The results highlight the need to provide education and awareness raising about MCI to enable people to seek help in a timely manner and be able to make informed lifestyle choices that may reduce their risk of MCI and dementia. Implementing education about MCI and dementia in schools is a key target, as younger people were the most uncertain or misinformed about these topics. It is clear that further public health initiatives around MCI are both warranted and welcomed by the general public.
