Gerontological social work has always been pulled between two impulses: helping older individuals adapt to the challenges of aging and reshaping the social structures that produce inequality in later life. This tension has driven the development of successive frameworks, each offering a different answer to the question of where change should be directed.
The first organized frameworks for social work with older adults emerged from the profession's early casework traditions. The Diagnostic School of Social Casework (1920–1960) drew heavily on psychoanalytic theory. Practitioners assessed the older client's internal psychological conflicts, often interpreting late-life depression, anxiety, or withdrawal as symptoms of unresolved earlier-life issues. The diagnostic method involved lengthy psychosocial histories and a focus on the clinician's expert judgment. In gerontological settings, this meant that an older person's difficulty adjusting to retirement or loss of a spouse might be framed as a failure of ego adaptation, requiring therapeutic insight rather than practical support.
The Functional School of Social Casework (1930–1970) arose in direct reaction to the Diagnostic School's assumptions. Instead of diagnosing internal pathology, the Functional School emphasized the helping process itself: the agency's function, the client's capacity for growth, and the use of time-limited, structured interventions. In gerontological practice, this shift was significant. Functional caseworkers did not assume that older adults were inherently fragile or resistant to change. They focused on the client's present ability to make choices within the constraints of aging, using the agency's resources—such as home care, senior centers, or financial aid—as tools for empowerment. Where the Diagnostic School saw a case history to be interpreted, the Functional School saw a relationship to be built around the client's own goals. The two schools coexisted for decades, but the Functional School's process-orientation laid groundwork for later strengths-based and client-centered approaches.
By the 1970s, both casework schools were challenged by frameworks that looked beyond the individual. The Life Model of Social Work Practice (1970–2000) introduced an ecological perspective: problems arise not from internal deficits but from poor fit between people and their environments. For older adults, this meant attending to the physical, social, and institutional contexts of aging—housing quality, access to transportation, family caregiving arrangements, and ageist policies. The Life Model directed practitioners to intervene at multiple levels: helping an older person adapt to a nursing home while also advocating for better staffing ratios. It preserved the clinical relationship but expanded its scope to include environmental modification.
Around the same time, the Life Course Perspective (1970–Present) offered a complementary but distinct lens. Drawing on sociology and demography, it emphasized that aging is a lifelong process shaped by historical events, social structures, and cumulative advantage or disadvantage. A gerontological social worker using this perspective would ask not just about current symptoms but about the trajectory of a person's life: how early poverty, war service, or gender discrimination shaped their resources and health in old age. The Life Course Perspective differed from the Life Model's ecological focus by foregrounding time and cohort effects. It showed that the problems of older adults are often the endpoint of long-term structural inequalities, not simply mismatches in the present environment. The two frameworks reinforced each other: the Life Model provided a practice method for improving person-environment fit, while the Life Course Perspective supplied a sociological explanation for why some groups of older people face worse fits than others.
The 1990s brought a cluster of frameworks that directly confronted deficit models and structural oppression. The Strengths-Based Approach (1990–Present) rejected the Diagnostic School's pathology focus and the Life Model's emphasis on deficits in the environment. Instead, it insisted that every older person possesses assets—resilience, wisdom, social networks, cultural knowledge—that can be mobilized. In practice, a strengths-based assessment might ask an older client about past coping strategies, community ties, and personal talents before identifying needs. This approach differed from the Functional School's earlier emphasis on client capacity by making strengths the explicit starting point of intervention, not just a byproduct of the helping process. It also differed from Critical Gerontology (below) by focusing on individual and community assets rather than on dismantling oppressive systems.
Critical Gerontology (1990–Present) emerged from political economy and feminist theory. It argued that aging is not a natural decline but a socially constructed experience shaped by capitalism, patriarchy, and ageism. Critical gerontologists examined how retirement policies, healthcare rationing, and age-based discrimination produce inequality. For social workers, this meant moving beyond individual adaptation to advocacy for systemic change—such as opposing mandatory retirement ages or fighting for affordable long-term care. Critical Gerontology shared with the Life Course Perspective an interest in structural forces, but it added an explicit political critique and a call for transformative action.
Anti-Oppressive Practice (1990–Present) extended this critique by focusing on intersecting oppressions—ageism combined with racism, sexism, classism, and ableism. In gerontological settings, an anti-oppressive practitioner would examine how an older Black woman's experience of aging differs from that of a white man, and how services might inadvertently reinforce those inequalities. Anti-Oppressive Practice differed from Critical Gerontology's political economy by centering identity and intersectionality, and from the Strengths-Based Approach by insisting that strengths cannot be separated from the power structures that constrain them. The three 1990s frameworks coexisted in productive tension: Strengths-Based offered a hopeful practice method, Critical Gerontology provided structural analysis, and Anti-Oppressive Practice demanded attention to multiple, overlapping forms of disadvantage.
Since 2000, Evidence-Based Practice (EBP) has become a dominant methodological framework across social work, including gerontology. EBP requires practitioners to integrate the best available research evidence with client preferences and clinical expertise. In gerontological settings, this has meant adopting interventions with proven efficacy—such as cognitive-behavioral therapy for late-life depression, caregiver support programs, or fall prevention protocols. EBP's appeal lies in its promise of accountability and effectiveness, especially in healthcare contexts where social workers must justify their services to insurers and interdisciplinary teams.
However, EBP's rise has created tensions with the critical and strengths-based frameworks. Critics argue that EBP privileges randomized controlled trials and quantitative outcomes, which may not capture the complex, relational, and structural dimensions of aging. An anti-oppressive practitioner might ask: whose evidence counts? A critical gerontologist might note that EBP rarely addresses systemic ageism or poverty. A strengths-based worker might worry that manualized interventions overlook the unique assets of each older person. These are not settled disagreements; they represent an ongoing negotiation among competing authorities.
Today, the leading frameworks in gerontological social work—Life Course Perspective, Anti-Oppressive Practice, Critical Gerontology, Strengths-Based Approach, and Evidence-Based Practice—agree on several points: aging is shaped by social context; older adults have agency and capacity; and effective practice requires attention to both individual and structural factors. They disagree on what should be prioritized: EBP emphasizes measurable outcomes, critical frameworks emphasize systemic change, and strengths-based approaches emphasize client assets. The field has not resolved this tension, and perhaps it never will. Instead, gerontological social workers learn to navigate among these frameworks, choosing the lens that best fits the situation—while remaining aware that each lens carries its own assumptions about what aging means and what help should look like.
