Abstract
Background/Objectives
Self-neglect is a complex, poorly understood public health problem associated with high morbidity and mortality. Previous qualitative research is limited to small samples and second-hand accounts, with a dearth of self-reported, comprehensive narratives in the geriatric population. Our goal was to identify patterns of personal experience or behavior in self-neglect by exploring narratives of cognitively intact older adults.
Design/Setting/Participants
We used qualitative data from a larger parent study of self-neglect characteristics. For our analysis, we evaluated interviews with 69 cognitively intact, self-neglecting older adults referred from 11 community-based senior services agencies.
Measurements
Interviews included a comprehensive psychiatric assessment using the Structured Clinical Interview for DSM-IV Axis-I and II Disorders (SCID-I and II), and an unstructured interview that allowed subjects to describe important elements of their life stories. We used content analysis to identify key personal experiences and behavior patterns within each subject's narrative.
Results
We identified 4 traumatic personal experiences and 5 behavior patterns in the life stories. Traumatic personal experiences included: psychologically traumatic loss, separation or abandonment (29%), violent victimization, physical trauma or sexual abuse (19%), exposure to war or political violence (9%) and prolonged mourning (7%). Maladaptive behavior patterns included: significant financial instability (23%), severe lifelong mental illness (16%), mistrust of people or paranoia (13%), distrust and avoidance of the medical establishment (13%), and substance abuse or dependence (13%).
Conclusion
Patterns of traumatic personal experiences and maladaptive behaviors frequently reported among self-neglecters were identified. Experiences, perceptions, and behaviors developed over a lifetime may contribute to elder self-neglect. Further exploration and improved understanding of these patterns may identify potential risk factors and areas for future targeted screening, intervention, and prevention.
Keywords: self-neglect, elder abuse, traumatic life events
Introduction
Self-neglect is the most frequent form of elder mistreatment investigated by adult protective services (APS) agencies.1,2 Elder self-neglect is defined as inability to meet self-care needs for physical, emotional, and social well-being.3 Self-neglecters may be found in dangerous environments because of inattention to home safety. Their health may be compromised by malnutrition, dehydration, and uncontrolled medical illness due to refusal of care. These self-neglecting behaviors lead to increased emergency department use,4 nursing home placement,5 and mortality.6 Despite its public health importance, the etiology of self-neglect remains poorly understood, and few effective interventions exist.7 Given the trends for growth in the geriatric population, a deeper understanding of elder self-neglect is urgently needed.
Self-neglect is currently thought to be a geriatric syndrome, resulting from interactions between poor social support, functional disability, chronic medical conditions, psychiatric illness, and mild cognitive impairment.8–10 Research has also suggested that an individual's social, cultural, and environmental circumstances over the course of a lifetime may impact self-neglecting behaviors.10 This qualitative research aims to improve understanding of older adults with different types of self-neglecting behavior by providing a unique, experiential perspective of self-neglecters. Previous qualitative research is limited to small samples11–13 and second-hand accounts,14 with a dearth of self-reported, comprehensive narratives in this population. The aim of this qualitative study is to identify frequently reported themes in the personal narratives of a large sample of community-dwelling, cognitively intact, self-neglecting older adults.
Methods
Overview
In this study, we qualitatively analyzed data initially gathered for a larger parent case-control study of community-dwelling, cognitively intact adults with and without self-neglecting behavior. The purpose of the parent study was to identify characteristics that differentiate self-neglecting and non-self-neglecting older adults. Subjects were enrolled into the parent study from 2008-2010. Potential subjects were referred from case managers and social workers at 11 community-based senior services agencies in the New York metropolitan area. These agencies were asked to refer clients aged ≥65 who lived in the community, were English or Spanish speaking, and were not cognitively impaired. Before enrollment, each subject was screened by the research team using the Mini-Mental Status Exam with a threshold score of ≥25. Subjects were informed that the purpose of the study was to learn about challenges in self-care faced by older adults and received up to $40 for participating in the study. Self-neglecters among the subjects were identified using criteria developed by the research team based on systematic review of the literature and verified by an expert panel including a geriatric psychiatrist (RA) and geriatrician (ML). These criteria for self-neglect included exhibiting ≥ 1 of: 1) inattention to personal hygiene, 2) inattention to living environment, 3) refusal of some or all indicated services, or 4) self-endangerment through the manifestation of unsafe behaviors. Only subjects determined to be self-neglecters by these criteria were included in the present qualitative analysis. All subjects were interviewed in their own homes or at a senior center of choice. This study was approved by the Weill Cornell Medical College Institutional Review Board.
Subject Interviews/Data Collection
In the parent study, each subject was evaluated in-person over two separate encounters. During the first encounter, subjects were interviewed to collect demographic information and to administer a battery of standardized instruments to test general health, functional ability, gait, mobility, vision, nutritional status, social networks, health related quality of life, and psychosocial well-being. The second interview consisted of the Structured Clinical Interview for DSM-IV (SCID-I and SCID-II), a standardized, semi-structured interview designed to identify current and lifetime DSM-IV Axis I and II diagnoses. The interviewers also asked the subjects to describe important elements of their life stories and collected field notes from these personal narratives. Subjects were not specifically prompted to discuss traumatic events. Here we report a qualitative analysis of SCID-I, SCID-II and all unstructured narrative field notes of self-neglect subjects.
Data Analysis
For this analysis, we examined data from 69 subjects. Two additional subjects did not complete the second interview and were excluded from our qualitative analysis. The interview responses and narrative notes were transcribed, reviewed, coded, and analyzed iteratively by three authors (CL, TR, EB), a geriatrics fellow, a geriatric emergency physician, and a public health gerontologist. We identified themes frequently reported by subjects using content analysis.15 In lieu of having coders working independently and calculating kappa based on coders' consistency, we used a consensus approach based upon the group interactive analysis component of Borkan's “immersion/crystallization” method.16 In this process, each rater identified frequently occurring themes by organizing and corroborating them with other members of the team. After coding was complete, we calculated the percentage of respondents that made statements corresponding to each identified theme. Using this process, we developed consensus around 4 traumatic personal experiences and 5 maladaptive behavior patterns.

Discussion
Patterns of Personal Experience
Traumatic Loss, Separation and Abandonment
Personal experiences of psychologically traumatic loss, separation and abandonment were frequently identified as important life events. They included unexpected losses or separation from an attachment figure at various ages in the context of forced displacement, accident, homicide, or suicide. Our findings are consistent with prior qualitative studies of elder self-neglect that have emphasized cumulative losses, betrayals, neglect, and abandonment over a lifetime.12,13 Unexpected or traumatic death of a loved one has been shown to significantly impact all age groups.17 Traumatic parental death in early life leaves individuals more vulnerable to psychiatric illness and substance abuse than parental death from other causes.18 Maladjustment following parental death during childhood, including development of poor self-esteem and insecure attachment styles has been shown to contribute to unstable relationships, poor social support and low resilience to external stressors in adulthood.19 In adulthood, unexpected death of a loved one has been linked to the development of major depression, alcohol or substance abuse, post-traumatic stress disorder (PTSD) and panic disorder.17 Acquired vulnerabilities in the aftermath of traumatic loss such as maladaptive coping strategies and psychiatric illness20 may contribute to the development of elder self-neglect.
Interpersonal Trauma
Experiences of interpersonal trauma perpetrated by family members, spouses, parental figures, and other close acquaintances emerged from the narratives. Subjects described violence, physical trauma, or sexual abuse at multiple stages in life. Interpersonal trauma in childhood including physical abuse, sexual abuse, and neglect have been shown to increase risks for severe mood disorders and behavioral disturbances in adolescence and adulthood.21,22 Interpersonal trauma occurring in late life may also predispose to behavioral disturbances. Among elderly adults referred to APS agencies for self-neglect, 28% of subjects had previously been victims of other forms of elder mistreatment.23 Elderly women who reported cumulative experiences of interpersonal violence over a life time reported feelings of social and emotional isolation, neglect and abandonment, low self-worth and loneliness.24 Trauma of victimization at various ages may heighten the risk for elder mistreatment and self-neglect.
Exposure to War or Political Violence
Subjects described separation, displacement and traumatic experiences in the context of war and political violence. Exposure to war and forceful displacement in early life may contribute to late-life maladaptive behavior and mental illness. Older adults displaced from their home country during World War II have reported greater frequency of traumatic events,25 poor resilience, greater anxiety, depression, and poor life satisfaction compared to non-displaced counterparts, even sixty years later.26 Among trauma-exposed refugees, losses of family members, abuse, and the lack of social support following displacement have been associated with PTSD and Prolonged Grief Disorder (PGD),27 a bereavement-related entity associated with adverse mental health outcomes including depression, PTSD and anxiety.28 Late-life consequences of war-related trauma and displacement may represent an important trigger to the onset of self-neglect.
Prolonged Mourning
Subjects frequently referred to the death of a spouse or child in adulthood as a significant life event, with yearning or grief persisting for many years. The psychological impact of such losses can be profound, yet no studies to date have explored the relationship between bereavement and self-neglect. A subset of bereaved individuals may develop PGD characterized by distrust and detachment from others, yearning for and avoidance of reminders of the deceased, a sense of emptiness or lack of meaning in life. Traumatic grief is associated with underutilization of health care services,29 suggesting diminished capacity for self-care in the aftermath of loss.
Patterns of Behavior
Financial instability
Self-neglecters in our study reported long-term, burdensome financial difficulties. Older adults with low income levels have been shown to have higher rates of self-neglect.9 Our findings are consistent with prior reports of significant financial difficulties among self-neglecters in the setting of unstable employment, substance use, mood disorders, and challenges navigating personal finances.11,12 Although some of our subjects reported financial hardship, with incomes at or below 150% of the federal poverty level at the time of the study, socioeconomic status among self-neglecting older adults is widely variable.30 It is also likely that many of our self-neglecting subjects had significant incomes. That even financially secure subjects emphasize burdensome financial difficulties when recounting their life experiences suggests that the perception of financial instability rather that instability itself may be an important contributor to self-neglect.
Lifelong mental illness
Subjects frequently described the impact of psychiatric illness in their lives including depression, anxiety, schizophrenia, and bipolar disorder. Many reported recurrent psychiatric hospitalizations and suicide attempts. This finding supports previous research suggesting that mental disorders are common in community-dwelling self-neglecters8 and increases risk of self-neglect.10
Mistrust of people or paranoia
Subjects described lifelong mistrust and avoidance of family, friends, neighbors and other people in the surrounding community. Previous qualitative studies of self-neglecters have also highlighted pervasive mistrust and estrangement, and alienation from family and friends.13 Socially isolative behavior may only be recognized as a component of self-neglect when the subject becomes functionally dependent as an older adult. Thus, age-related frailty may be a “catalyst,” causing a shift such that isolating behaviors increase risk of self-harm.12
Distrust and avoidance of the medical establishment
Avoidance of doctors and hospitals was a recurrent theme among study subjects, often in the context of negative prior experiences. Refusal of medical intervention and social services is a feature of self-neglect frequently described in the literature.11,13 Fear of institutionalization may drive older adults to remain in self-endangering situations.
Substance abuse or dependence
Substance abuse, particularly alcoholism was frequently described in the narratives. Among community-dwelling self-neglect subjects, alcohol-related problems are commonly reported.8 Both alcoholism and illicit drug use may lead to financial instability, eviction, unemployment and other psychosocial factors contributing to poor self-care and breakdown of social support networks among self-neglecters.11
Conclusions
To our knowledge, this is the largest sample of self-neglecting older adults qualitatively analyzed and provides a unique, experiential perspective of elder self-neglect. Themes of traumatic life events in both childhood and adulthood and maladaptive behaviors emerged. Our analysis supports existing research on the contribution of social, cultural, and environmental factors to self-neglecting behaviors10 and offers insight into vulnerabilities developed over a lifetime. Potential populations identified for targeted intervention include geriatric victims of even remote interpersonal violence or traumatic loss, trauma-exposed populations in the aftermath of war, victims of complicated bereavement, substance abuse, financial insecurity, and psychiatric illness. Further understanding of the impact of traumatic personal experiences and maladaptive behaviors may inform elder self-neglect prevention, screening, and intervention efforts.
Limitations
Our research has several limitations. Findings from cases of self-neglect from a single U.S. metropolitan area identified by senior service organizations may not be generalizable. Our work relies on analysis of self-reported, unstructured field notes that were not initially gathered for this study. Another limitation is the unique sampling of self-neglecters who agreed to participate, were cognitively intact, and had connected with community services. Given the recruitment challenges of extreme self-neglecters, who often avoid contact with the healthcare system, the most severe cases of self-neglect may not be represented in our sample. Nevertheless, exploring the subjective experiences of self-neglecting older adults contributes to the conceptual understanding of this phenomenon. Our conclusions do not rely on event accuracy, but on the emotional and experiential aspects that have influenced subsequent behavior in old age. Also, our analysis did not include a comparison group of non-self-neglecting subjects. It is possible that older adults who do not exhibit self-neglect may report similar experiences and behaviors. Self-neglecters and non-self-neglecters may emphasize different experiences, or differ in their resilience and coping abilities in the aftermath of traumatic experiences and external stressors. Further exploration of these differences is an important next step in self-neglect research.
