中高齡人口一直是志工人力的主要來源，但過去很少有研究探討中高齡志工服務時可能遭遇的問題，故本研究主要在探討影響中高齡志工服務困境的影響因素，並以北部某縣市為研究場域。在本研究中，志工服務困境共有11項，並以性別、年齡、教育程度、有無工作、志工角色、服務年資、有無服務紀錄冊、家人有無從事志願服務為預測變項，於2021年3至5月進行問卷調查，回收有效問卷1,342份。研究結果顯示，志工所擔任的角色是影響其遭遇服務困境的主要因素，尤其是擔任志工督導／業務承辦人員的角色，在推動服務工作時較容易遭遇到各種的困難，因而值得吾人去關心和協助，研究者據此提出結論和建議。

The middle-aged and older adult population has always been the main source of volunteer manpower. This study mainly explores the main factors influencing the challenges faced by middle-aged and older adult volunteers, focusing on a county and city in northern Taiwan as the research area. The study considered 11 aspects of volunteer service difficulties, with predictive variables including gender, age, education level, job availability, volunteer role, service years, availability of service record books, and whether family members are engaged in volunteer service. Questionnaire surveys were conducted from March to May 2021, and 1,342 valid questionnaires were collected. The research findings indicate that the role played by volunteers is the main factor affecting their service difficulties, especially for those serving as volunteer supervisor in charge of volunteer business, who are more likely to encounter difficulties in promoting services. Therefore, their well-being is deserving of our attention and assistance. Based on these findings, the researchers propose conclusions and suggestions.
