This qualitative phenomenological study explores the lived experiences of senior male persons deprived of liberty (PDLs) aging within the Agusan del Norte Provincial Jail employing photovoice methodology complemented by semi-structured interviews and focus group discussions, the study captures participants personal narratives through drawings and verbal reflections. Anchored primarily on Erikson’s Psychosocial Development Theory, the study examines how senior male PDLs navigate the psychological challenges of late adulthood. The study highlights the multifaceted challenges faced by senior male PDLs, including chronic physical health issues, inadequate medical care, emotional distress from family separation, and institutional limitations that restrict mobility and autonomy. The slow passage of time and pervasive loneliness exacerbate psychological suffering, while family connections and spiritual faith emerge as vital sources of meaning, hope, and resilience. Participant’s artworks reveal deep themes of vulnerability, longing, and acceptance, illustrating how they find meaning through faith, family, and altruistic acts, despite the harsh realities of prison life. Findings underscore the urgent need for age-responsive prison policies and programs that address healthcare deficits, promote psychosocial support and facilitate meaningful social engagement. The study proposes “Art Behind bars” an advocacy initiative using senior PDLs artworks to raise awareness, foster empathy, and drive systematic reforms. This research contributes to criminological knowledge on aging in correctional settings, advocating for humane, dignified treatment that supports successful aging among senior male PDLs.
