Final answer:
Rosenfeld's research ('Identity Careers of Older Gay Men and Lesbians') focuses on the identity careers of older gay men and lesbians, exploring their challenges in managing sexual identity and forming support systems as they age, as well as the need for policy improvements to support the aging LGBTQ community.
Step-by-step explanation:
Rosenfeld's research, specifically referred to as 'Identity Careers of Older Gay Men and Lesbians,' primarily focused on the identity careers of older gay men and lesbians. This area of study addresses how these individuals navigate their sexual and relationship identities, particularly as they face aging and the various challenges that come with this stage of life, such as entering long-term care facilities, coping with laws and societal attitudes towards homosexuality, and managing the disclosure of their sexual identity.
Key issues highlighted in the research include the higher rates of disability and depression among LGBTQ older adults, the complexity of forming a support system, the impact of same-sex marriage legislation on aging, and the importance of policy improvements to support the aging LGBTQ community. The challenges faced by LGBTQ individuals in later life, such as the selective disclosure of sexual identity and managing legal and financial protections, are crucial aspects of Rosenfeld's work.
