Abstract

Loneliness among older adults living independently in the community is increasingly recognised as a significant public health concern in the United Kingdom, associated with elevated risks of depression, cognitive decline and premature mortality. Despite a growing policy focus on tackling loneliness, evidence on which community-based interventions are most effective, and why, remains fragmented. This dissertation reports a mixed-methods study exploring the experience and mitigation of loneliness among adults aged 65 and over participating in a community befriending scheme in a mid-sized English town. A sequential explanatory design was used, comprising a cross-sectional survey of scheme participants (n = 148), measured using the UCLA Loneliness Scale and a bespoke wellbeing questionnaire, followed by semi-structured interviews with a purposive subsample of twelve participants. Quantitative analysis found a statistically significant reduction in mean loneliness scores among participants who had engaged with the scheme for six months or more compared with recent joiners, while thematic analysis of the interview data identified continuity of relationship, a sense of reciprocity, and perceived choice over participation as the mechanisms most consistently associated with reduced loneliness. The findings suggest that befriending schemes are most effective where they are designed to foster sustained, mutually valued relationships rather than one-off or purely transactional contact. The dissertation concludes with recommendations for commissioners and service providers regarding scheme design, volunteer matching and the measurement of loneliness outcomes in community-based interventions, together with an assessment of the study’s limitations and directions for future research.

Introduction

1.1 Background and Context

Loneliness, defined as the subjective, unwelcome experience of a discrepancy between desired and actual social relationships, has become a prominent concern in UK health and social policy over the past decade (Office for National Statistics, 2023). Population surveys consistently indicate that a substantial minority of adults aged 65 and over report feeling lonely often or always, with prevalence rising further among those who are widowed, living alone, or affected by mobility-limiting long-term conditions (Age UK, 2022). The health consequences associated with chronic loneliness are well documented: longitudinal cohort evidence links sustained loneliness to increased risk of depression, accelerated cognitive decline, and all-cause mortality comparable in magnitude to established risk factors such as physical inactivity (Holt-Lunstad, Smith and Layton, 2015; Cacioppo and Cacioppo, 2018). Beyond individual health outcomes, loneliness among older people carries a wider economic and service burden, associated with more frequent primary care consultations and, in some studies, higher rates of unplanned hospital admission, adding a health-system rationale to the ethical case for intervention (Valtorta et al., 2018).

Recognition of these harms has translated into policy action. Following the Jo Cox Commission on Loneliness, the UK government published its first cross-departmental loneliness strategy in 2018 and has since funded a range of local and national initiatives, including social prescribing schemes that enable general practitioners and other primary care staff to refer patients to non-clinical community activities, of which befriending schemes are among the most common (Department for Digital, Culture, Media and Sport, 2018). Community befriending, in which trained volunteers are matched with an older person for regular, ongoing contact, has attracted particular policy interest because it is comparatively low-cost to deliver and is reported by many participants and providers to be well received; however, the evidence base regarding which specific features of such schemes drive measurable reductions in loneliness remains considerably less developed than the policy enthusiasm for the model itself (Windle, Francis and Coomber, 2011).

The present study is situated within one such scheme, operated by a local voluntary-sector organisation in a mid-sized English town, which matches trained community volunteers with older residents referred primarily through social prescribing links from local general practices, alongside a smaller number of self-referrals. The scheme has operated for several years and has an established base of ongoing volunteer–participant matches of varying duration, providing a naturally occurring opportunity to compare the experiences and outcomes of participants at different stages of engagement, which forms the basis of the comparative element of the research design described in Chapter 3.

1.2 Problem Statement and Rationale

A recurring criticism of the loneliness-intervention literature is that existing evaluations frequently report whether an intervention was associated with improved outcomes without adequately explaining the mechanisms through which any such improvement occurred, limiting the extent to which findings can inform the design of new or existing schemes (Gardiner, Geldenhuys and Gott, 2018). Systematic reviews further note that many published evaluations rely on small, uncontrolled samples, short follow-up periods, or purely qualitative accounts that, while valuable for understanding participant experience, cannot establish whether observed changes in wellbeing are associated with measurable, quantifiable change in loneliness itself (Dickens et al., 2011). This creates a practical problem for commissioners: local authorities and health bodies are under sustained pressure to demonstrate the value of loneliness-reduction spending, yet the available evidence offers comparatively limited guidance on which specific design choices, such as the duration, frequency, or matching approach used within a befriending scheme, are most strongly associated with outcome improvement.

A further, related gap concerns the relative neglect of participants’ own explanatory accounts within the existing evidence base. Where qualitative work has been conducted, it has more commonly focused on participant satisfaction with a scheme than on the specific relational or structural features that participants themselves identify as driving any change in how lonely they feel, a distinction that matters because satisfaction with a service does not necessarily indicate that the service has altered the underlying experience the intervention was designed to address (Gardiner, Geldenhuys and Gott, 2018). Without this more explanatory layer of evidence, providers seeking to refine scheme design, for example by adjusting volunteer training, matching criteria, or the expected frequency and duration of contact, have limited empirical grounding for such decisions beyond professional judgement and anecdotal feedback.

The present study responds to this gap by combining a quantitative assessment of change in loneliness scores with a qualitative exploration of participants’ own accounts of what, within their experience of the scheme, contributed to any change they experienced. This combination is intended to move beyond a simple before-and-after outcome measure towards an explanation of mechanism that can more directly inform scheme design and commissioning decisions, addressing a specific, locally relevant instance of the wider evidentiary gap identified in the literature, while also generating findings of plausible relevance to comparable befriending schemes operating elsewhere in the UK.

1.3 Aims and Objectives

The aim of this study is to explore the experience and measurable mitigation of loneliness among older adults participating in a community befriending scheme, and to identify the features of the scheme most closely associated with reduced loneliness. This aim reflects both the practical orientation of the study, towards findings that can directly inform the host organisation and comparable providers, and its explanatory ambition, towards a fuller account of mechanism than the outcome-only evaluations more commonly reported in the literature discussed above. The aim is addressed through three specific objectives, each mapped to a distinct stage of the research design set out in Chapter 3:

1. To measure change in loneliness and wellbeing scores among befriending scheme participants, comparing those with differing lengths of engagement with the scheme, using validated quantitative instruments administered via a cross-sectional survey.
2. To explore, through semi-structured interviews with a purposive subsample of participants, their own accounts of the relationships and experiences within the scheme that they associate with changes in their sense of loneliness, allowing space for explanations not anticipated by the survey instrument.
3. To integrate the quantitative and qualitative findings in order to identify the specific design and delivery features of the scheme most consistently associated with reduced loneliness, and to translate these into practical recommendations for service design and commissioning.

1.4 Research Questions

The study is guided by three research questions, each corresponding to one of the objectives above and addressed through the specific analytical approach detailed in Chapter 3.

RQ1. Is length of engagement with the befriending scheme associated with a measurable difference in loneliness and wellbeing scores among participants? This question is addressed quantitatively, comparing survey scores between participants grouped by duration of engagement, and provides the outcome-level evidence against which the qualitative findings can subsequently be interpreted.

RQ2. How do participants describe the relationships and experiences within the scheme that they associate with any change in their sense of loneliness? This question is addressed through inductive thematic analysis of the interview data, allowing participants’ own language and priorities, rather than a predetermined coding frame, to shape the resulting account of mechanism.

RQ3. Which specific design and delivery features of the scheme are most consistently associated, across both the quantitative and qualitative findings, with reduced loneliness among participants? This integrative question is addressed in the Discussion chapter, where the quantitative pattern of association identified under RQ1 is read alongside the explanatory themes identified under RQ2, in order to identify convergent, triangulated findings suitable for translation into the practice recommendations set out in the concluding chapter.

1.5 Significance of the Study

This study is significant in two respects. Practically, its mixed-methods design is intended to generate findings of direct use to the host organisation and to other providers and commissioners of similar schemes, offering evidence-informed guidance on scheme design, volunteer matching and the measurement of outcomes that can inform funding bids and service-improvement decisions beyond the immediate research setting. In a funding environment where voluntary-sector providers are increasingly required to demonstrate outcome evidence to secure continued commissioning, a study capable of linking specific, actionable design features to measurable outcome change has practical value well beyond a single scheme evaluation.

Theoretically, the study contributes to the developing literature on the mechanisms of loneliness interventions by testing, in a single coherent design, whether participant-reported relational mechanisms such as continuity, reciprocity and perceived choice correspond with measurable quantitative change, addressing the mechanism-evidence gap identified in Section 1.2. This framing draws loosely on social convoy theory and the broader social-relationships literature, which distinguish between the mere presence of social contact and the perceived quality, reciprocity and continuity of relationships as the more proximal determinants of loneliness reduction (Cacioppo and Cacioppo, 2018). In doing so, the study responds directly to calls in recent systematic reviews for mixed-methods evaluations capable of connecting outcome measurement to explanation, rather than reporting either in isolation (Gardiner, Geldenhuys and Gott, 2018; Dickens et al., 2011).

1.6 Definitions and Scope

Two terms used throughout this dissertation require clarification at the outset. First, loneliness is distinguished here from social isolation: the latter refers to an objective, measurable paucity of social contacts or interactions, whereas loneliness refers to the subjective, felt experience of unwanted disconnection, such that an individual with relatively few social contacts may not report feeling lonely, while an individual with an apparently active social network may nonetheless experience significant loneliness (Cacioppo and Cacioppo, 2018). This dissertation is concerned specifically with the subjective experience of loneliness, measured using the UCLA Loneliness Scale, rather than with social isolation as an independent construct, although the two are treated in the literature review as related and overlapping. Second, the term ‘befriending scheme’ is used throughout to refer specifically to structured, volunteer-delivered programmes that establish an ongoing, one-to-one relationship between a trained volunteer and an older participant, distinguishing this model from group-based social activities, telephone-only befriending services, or purely digital interventions, none of which are the subject of the present study.

The scope of the study is similarly bounded in three respects. It examines a single scheme operating within one town, rather than a national or multi-site sample, which affects the generalisability of the findings as discussed further in Chapter 5. It focuses on adults aged 65 and over who are living in the community rather than in residential or nursing care, a population for whom the drivers of loneliness and the feasibility of befriending-style interventions may differ materially. Finally, it addresses loneliness as its primary outcome of interest, drawing on wellbeing as a secondary, complementary measure, rather than attempting to assess the scheme’s wider impact on outcomes such as physical health or healthcare utilisation, which lie beyond the scope of the data available for this dissertation.

1.7 Structure of the Dissertation

The remainder of this dissertation is organised into five further chapters. Chapter 2 presents a review of the literature on loneliness in older adulthood, its health consequences, and the evidence base for community-based interventions, situating the present study within this wider body of work and developing the conceptual framework that informs the research design. Chapter 3 sets out the study’s mixed-methods sequential explanatory design, describing the survey instrument, sampling strategy, interview protocol, and the ethical considerations addressed in conducting research with older adults, including approaches to informed consent and safeguarding. Chapter 4 reports the study’s findings, presenting the quantitative survey results first, followed by the themes identified through analysis of the interview data. Chapter 5 discusses these findings in relation to the existing literature, considering both points of convergence and divergence, and reflects critically on the study’s limitations, including the boundaries of scope set out in Section 1.6. Chapter 6 concludes the dissertation with a summary of the study’s contribution, practical recommendations for scheme design and commissioning, and suggestions for future research building on the findings presented here.
