Prejudices and elderly patients’ personality – the problem of quality of care and quality of life in geriatric medicine

Background

PERSONALITY VARIATION IN LATE ADULTHOOD:

The study of development of personality in adulthood has been widely discussed in the literature [1,9]. In general it is assumed that in old age personality changes, mostly due to cognitive decline. However, the influence of the individual’s social environment on personality traits can be also very significant as well as life history. This approach is developed mostly by the contextualists [9]. According to a transactional perspective on mean-level personality changes, the different normative experiences lead to the advancement of personality growth. In late adulthood, for example, there are some important social role domains that undergo changes; these are connected with an urgent need to redefine personal identity after retirement [1], with grand-parenting children and some volunteering [10], and with the feeling of loss that accompany the deaths of relatives and intimate friends. The current literature provides some hints about how personality traits change. It is predicted that agreeableness, which is linked to prosocial behaviors [9], should undergo changes, as well as conscientiousness linked to work commitment [9]. Moreover other theories suggest that as people grow older they become more mature at emotional regulation [1,9]. This should lead to decline in neuroticism with age. According to socioemotional selectivity theory, the levels of openness and extraversion decline, and agreeableness increases [9]. These changes are provoked mostly by the social marginalization of the old. Knowledge about how personality traits change across the life span may help physicians and other healthcare providers in offering more effective services. This process must take consecutive steps: changing their viewpoints, altering their attitudes towards the old, and replacing ageist practices with positive behaviors.

Material and Methods

The present study was designed to test a hypothesis about adult personality changes during different developmental stages. The sample included 164 subjects aged 19–92 years who were all research volunteers recruited through word of mouth. Personality data were available for 108 women (66%) and 56 men (34%). The detailed information on age is presented in Table 1. Late adulthood was divided into 2 subgroups – young, old, and older old – to study the differences of less and more advanced age.

To measure the Big Five personality dimensions, all participants filled out the NEO Five-Factor Inventory (NEO-FFI) [11]. The NEO-FFI items are short and easy-to-understand phrases to assess neuroticism, extraversion, openness to new experiences, agreeableness, and conscientiousness. The psychometric properties and measuring qualities of the inventory have been investigated and approved. The NEO-FFI items are rated on a 5-point scale ranging from 1 – disagree strongly to 5 – agree strongly[11]. The study was carried out in a paper and pencil format. Statistical analysis included descriptive statistics, comparison of mean scale values using analysis of variance, and cluster analysis.

Results

For purposes of statistical analysis we compared the results received into 3 age groups: early adulthood, the young old, and the older old. The obtained differences among the mean scores are in accordance with studies of mean-level change in the Big Five [9]. The trends are stable: conscientiousness and agreeableness tend to increase with age, but extraversion does not change significantly. The basic pattern of neuroticism decline is found in the young old period. Later in life, the results tend to increase (Table 2 and Figure 1).

To evaluate the significance of the obtained differences of the mean scores, we ran analysis of variance. A significant group effect was found for 3 traits: openness to new experiences, conscientiousness, and agreeableness. The differences among the means of neuroticism and extraversion in the 3 analyzed groups were not significant (Table 3).

Cluster analyses were performed to test for more descriptive change patterns. The data showed some interesting age effects. The clustering techniques showed some differences in taxonomies of personality traits. In general, a horizontal hierarchical tree plot proved that the patterns according to which the traits aggregate in youth and young old groups are quite similar.

In both subsamples, neuroticism showed the strongest uniqueness of all traits. Although in the old old this tendency was also found, the distance between neuroticism and the other aggregated traits was smaller. Analyzing the similarities among traits in 2 age groups (youth and young old), the most similar ones were agreeableness and extraversion. In the old old group, the first cluster was composed of agreeableness and conscientiousness (Figure 2).

Discussion

HEALTH CARE AND THE QUALITY OF LIFE:

The old are the marginalized and often ignored. The first step to change this is to convince the healthcare providers to revise their beliefs about geriatric patients’ personalities. Using the results of the present study, they should learn that there is no specific age-determined pathology in personality traits taxonomy. This novel insight into the nature of ageing may stimulate some changes in their professional practices and thus improve the quality of life of the elderly patients. This is because the main issue in healthcare situations concerns the problem of balance between extending life and assuring that this life remains worth living [12].

The pitfalls of thinking about geriatric patients and their position lead to serious misunderstandings and lack of care. Examples of disregard for elderly patients among medical staff are common and include frequent misdiagnosis, ignorance of important symptoms, and communication barriers [8]. This situation resembles a self-perpetuating cycle of despair and resignation.

The last few years have seen a considerable amount of research and publications on the issues of the greying population. Thus, we may admit that the position of an average elderly patient does not resemble that described in sophisticated models of “geroscience”. Although we should be critical of some overgeneralizations, we should also agree on common practices. If we take into account the characteristics of quality of life (QoL) of the old, we come up with some general conclusions:

The last problem is the most important to be recognized and discussed further in detail. Social environment, attitudes, stereotypes, and prejudices play a central role in modelling the elderly’s concept of being a patient and in defining the range of responsibility and possible tasks for the patient. Unfortunately, the elderly are most often thought to adapt to being handicapped. In social perception, the old fit the “handicap profile” well. In the International Classification of Impairments, Disabilities, and Handicaps (ICIDH), a handicapped person is one whose ability to survive is limited in at least one of the following areas: 1) orientation, 2) physical independence, 3) mobility, 4) occupations, 5) social integration, 6) economic independence, and 8) other domains [13]. Most of the listed domains of handicap are prescribed to the elderly people and also relate to their quality of life [13]. Gaillard et al. [15] proved empirically that older adults exposed to age-related stereotypical expectations had worse performance. In other words, the elderly’s self-regulatory mechanisms are prone to stereotype threat effects. Furthermore, they influence the elderly’s well-being. This is only one example of numerous external forces impinging on the elderly’s self-esteem and QoL (see: double/triple jeopardy [1], internalized ageism [16]). The impact of possible significant shifts in specialists’ attitudes to ageing and to older adults is almost certain to improve the quality of lives of future cohorts of older patients. If healthcare providers approach older people with adequate knowledge and an open mind, the future generations of the elderly, as Stuart-Hamilton states, will stand up for what they want, rather then what younger adults are foisting on them ‘for their own good’ [1].

There are many possible predictors of personality (e.g., genes, cultural and social contexts, and individual experiences. Among all of them, there is also an evident age effect. In this article we attempted to sensitize the healthcare workers and raise their awareness about the quality of personality changes in late adulthood. The presented data proves that the ageist view on geriatric patients is a serious misjudgment and the starting point to search for solutions to improve the standards of caring for the elderly that will be positively evaluated from both receivers’ and providers’ points of view. This is important in the geriatric patients’ current situation when many medical services and devices are inaccessible and too expensive. The irregular and insufficient utilization of healthcare services is also due to their poverty, immobility, misconceptions, and misinformation of the necessity of constant compliance with treatment plans and drug regimens. Thus, it is impossible to overstate the importance of any attempts to improve the quality of geriatric care.

A proper attitude toward geriatric patients helps physicians, therapists, and caregivers to provide adequate care at a lower cost and delay admission into high-cost institutional care. It leads to using home-care in place of geriatric and hospice care. But to achieve it, physicians must demonstrate better recognition of the clinical, functional, and individual implications of ageing. They should also become more reliable and trustworthy in the elderly’s view. The improvement of elder care lowers psychological burdens of patients. The safe and nurturing environment created by specialists, patients, and their relatives cooperating together provides numerous benefits such as higher emotional and social support for patients’, better health outcomes for patients, and lesser damage to the health of caregivers. This paper argues that we can enhance the probability of success through the education and training of healthcare providers and then disseminating the evidence for improvements through the knowledge-to-action cycle.

The interest in personality has many meaningful outcomes in the fields of diagnosis and therapy [14]. Physicians as well as therapists and caregivers must learn how to use the knowledge of personality traits in better understanding the progress of a disease. It is good to know that patients with different personalities may manifest the symptoms of diseases with different indicators at different points in time. Furthermore, physicians and healthcare providers should also be aware of the fact that patients with different personalities may be prone either to health-damaging behaviors or health-promoting actions. Depending on their personality traits, patients are more or less open to change, more or less motivated to recovery from illness, and prefer and choose different strategies for coping with acute and chronic illness. It improves the satisfaction with one’s own activity, even in conditions of limitations, which allows for some degree of recompense for the impact of ageing on the functioning of the elderly person, which is important for quality of life [17–19]. All these facts prove how useful personality diagnosis may be for improvement of medical and social care for the elderly.

Conclusions

The results challenge the stereotypes that present older people as neurotic and aggressive. Age did not significantly correlate with the level of neuroticism and extraversion. In general, the obtained results prove that the ageist assumption that geriatric patients are troublesome is false. This article builds support for effective change in geriatric professional practices and improvement in the elderly patients’ quality of life.
