Abstract

Mental health disorders, such as depression and anxiety, continues to be major concern in various occupations; foremost of which are the aviation industry employees since their work environments involve extreme job demands, heavy workloads, and management issues. The high levels of depression and anxiety at the workplace evidently influences the staff and organizational performance. While prior studies exist, there remained contextual, conceptual and methodological gaps that needed to be addressed. This study assessed depression, anxiety and staff performance of Kenya Airports Authority security wardens at Jomo Kenyatta International airport, Nairobi, Kenya. Specific objectives included determining the prevalence of depression and anxiety, identifying the key risk factors, and establishing the correlation between depression and anxiety. The study was quantitative in nature and used a descriptive cross-sectional research design. A random sampling technique was utilized to select 64 Kenya Airports Authority security wardens. Data was collected through structured questionnaire, which was pre-tested on 10% of the sample population to ensure validity and reliability of the data collection instrument. Statistical analysis of the results was performed using the latest version of Software Package for Social Sciences (SPSS). The analysis was interpreted, and data presented in table for uniformity and ease of interpretation. The main findings from the study sample comprised: both anxiety and depression are prevalent issues for Kenya Airports Authority security wardens, although anxiety appeared to have a more frequent impact on task completion; majority of respondents indicated they experienced moderate levels of both anxiety and depression; and several workplace stressors were noted to cause mental health challenges, influencing staff performance negatively. In this regard, the study recommended that organizations recognize anxiety and depression as significant mental health issues; and suggested that they take necessary measures and mental health support to enhance both productivity and employee well-being.
