One Experience, Three Research Objects: Loneliness Among Homebound Older Adults in a Rural County Seen Through Postpositivist, Interpretive and Critical Paradigms

Introduction

A paradigm decides what a researcher is allowed to find before any data arrive. It sets what exists to be studied, how it can be known and what counts as good evidence. This paper shows that commitment at work on one experience: loneliness among older adults who rarely leave their homes in a composite rural county of about 18,000 people, where the nearest grocery store and clinic are a thirty-minute drive for many residents and public transport runs twice a week. Home health nurses in the county describe clients who say they go days without speaking to anyone. The paper follows the same experience through three paradigms, postpositivist, interpretive and critical, and shows each turning it into a different research object with its own acceptable evidence.

Weaver and Olson (2006) describe paradigms in nursing research as sets of assumptions about reality, knowledge and method that guide inquiry, and they argue that each paradigm contributes different knowledge. The point of this paper is not to rank them but to make visible what each one allows and forbids.

Why Loneliness Is Worth the Test

Loneliness is a good test because it has an established public health profile and an intensely private character. A meta-analysis of prospective studies found that loneliness and social isolation were associated with increased risk of mortality (Holt-Lunstad et al., 2015). A national report on older adults argued that the health care system is an important and underused point of contact for identifying and addressing social isolation and loneliness (National Academies of Sciences, Engineering, and Medicine, 2020). Yet what loneliness is like, and why it happens to one person and not another, depends on life histories that no survey item captures. The same phenomenon can therefore be studied in very different ways, which is what makes it useful here.

The Postpositivist Paradigm: Loneliness as a Measurable Variable

In the postpositivist paradigm, reality exists independently of the researcher but can only be known imperfectly, through careful measurement and the testing of hypotheses. Loneliness becomes a variable: a quantity that differs between people and can be related to other variables. A study in the county might ask whether loneliness scores are higher among residents living more than twenty miles from town, controlling for age, health and household size.

The acceptable evidence is a validated measure and a representative sample. The revised UCLA Loneliness Scale, for example, measures subjective feelings of loneliness and social isolation through a set of items rated for frequency, and its reliability and factor structure have been examined across samples (Russell, 1996). Good evidence here is a score that can be compared across people and linked to predictors or outcomes.

What this paradigm allows is comparison, prediction and eventually the testing of interventions, such as whether regular phone calls from volunteers reduce loneliness scores. What it forbids, or at least sets aside, is the meaning of loneliness to the person experiencing it. A widow whose loneliness centers on the loss of a particular voice at the kitchen table and a man who has always preferred solitude but now cannot drive to church may have the same score and entirely different experiences.

The Interpretive Paradigm: Loneliness as Lived Meaning

In the interpretive paradigm, what is real is built up out of how people experience and interpret their lives, and knowledge comes from understanding how people make sense of their lives. Loneliness becomes an experience to be understood from the inside. A study in the county might ask what it is like to grow old at the end of a long gravel road, and how residents themselves describe being alone.

The acceptable evidence is the participants' own accounts, gathered through in-depth interviews and interpreted with attention to context. Quality is judged not by statistical validity but by criteria such as credibility and transferability, whether participants would recognize the findings as true to their experience and whether enough context is given for readers to decide if the account fits other places (Weaver & Olson, 2006).

What this paradigm allows is depth. It could reveal, for example, that many residents distinguish between being alone, which they value, and being forgotten, which they fear, and that the arrival of the home health nurse matters less for the visit itself than for the sense of being remembered. What it forbids is generalization in the statistical sense. It cannot say how common that distinction is in the county or whether an intervention reduced loneliness across a population.

The Critical Paradigm: Loneliness as a Product of Structure

In the critical paradigm, reality is shaped by social, economic and political structures, and knowledge should expose those structures and support change. Loneliness becomes a product of conditions: the closing of the county's rural post offices and churches, the end of a bus route, the lack of broadband that makes video calls impossible and the migration of younger people to cities. A study in the county might ask how decisions about transport, services and infrastructure produced isolation among older residents, and who made those decisions.

The acceptable evidence includes documents, policy records and the testimony of residents, often gathered in partnership with them so that the research itself shifts some power toward the community. Quality is judged partly by whether the research contributes to change.

What this paradigm allows is attention to causes that neither measurement nor interpretation locates in individuals. What it forbids, or at least subordinates, is loneliness as a private feeling. A resident whose loneliness has little to do with transport, such as a man grieving his wife, may fit poorly into an analysis centered on structures.

What the Comparison Shows

The three paradigms do not study the same object. The postpositivist study measures a variable; the interpretive study understands an experience; the critical study exposes a structure. Each has its own evidence and its own blind spot. Choosing a paradigm is therefore not a technical choice about methods made after the question is set. It shapes the question itself.

For a DNP project in the county, the choice would depend on what the project needs to do. A project testing a telephone outreach program would need postpositivist measures to show whether loneliness changed. A project designing outreach would benefit from interpretive understanding of what residents value, such as being remembered. And a project seeking a new bus route would need the critical view. Knowing which paradigm a project rests on, and what it forbids, is what keeps the project honest about what it can claim.
