The Effects of a Care Program Based on the Roy Adaptation Model on Nursing Home Residents’ Quality of Life

1. Background

Aging was defined by the world health organization (WHO) as an age more than 60 years old (1). During the aging process, people usually undergo different physiological, psychological and social changes (1). Recent medical and health-related advances relatively increased humans’ longevity. Consequently, aging population is increasing progressively throughout the world and even in the developing countries such as Iran (2). The rate of global population growth is 1.7% while the global aging population growth rate is 2.5%. In 2011, people who aged more than 60 constituted 8.2% of the total Iranian population and it is estimated that the aging population in Iran will reach 10.5% by 2025 and 21.7% by 2050 (3).

Aging negatively affects elderly people’ health and progressively increases the rates of age-related problems and complications such as multiple organ dysfunctions. One of the commonest age-related complications is physical dysfunction which undermines elderly people’s independence and enhances their need for help (4). Given the debilitating complications of aging, care-related activities and strategies should pay a special attention to elderly people’s quality of life (QOL). Healthcare measures for elderly people are considered effective provided that they improve QOL. Currently, the concept of active aging is introduced which denotes that the aim of supportive measures for elderly people should not be merely to increase their life expectancy; rather, healthcare services should focus on improving their QOL as well (5).

As a key health-related concept, QOL is highly valued by international organizations such as WHO. This organization defined QOL as “individuals’ perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards, and concerns” (6). Alongside with progressive increase in aging population, improvement of elderly people’s QOL is also received an international attention (4, 6). Therefore, many studies focused on factors which affect QOL including health, family, interpersonal relationships, role performance and recreational activities (7, 8). The most critical factor behind elderly people’s QOL is their health (9). QOL has different aspects grouped into three closely-interrelated main categories of physical, psychological and social (10). Improving elderly people’s QOL and modifying their lifestyles can considerably promote their independence and efficacy and help them effectively manage their age-related complications and problems (11).

Age-related physical and mental health problems reduce elderly people’s QOL and limit their ability to adapt to aging. These problems are manifested in unhealthy and maladaptive behaviors. Accordingly, healthcare measures are needed to change elderly people’s unhealthy and maladaptive behaviors to healthy and adaptive ones (12). To facilitate behavior modification, healthcare professionals can use adaptation-related theories, particularly the Roy adaptation model (RAM) (13).

In her theory, Roy considered an individual as a comprehensive set which consists of physical (physiological) and psychological (self-concept, role function and interdependence) domains. Thus, holistic adaptation occurs once a person achieves adaptation in these two domains or four modes (14). According to Roy, adaptation is affected by three main stimuli including focal, contextual, and residual. Therefore, adaptation can be promoted through manipulating these stimuli during the process of care delivery. The main reasons behind clients’ maladaptive behaviors (i.e. focal, contextual and residual stimuli) can be identified through assessing clients’ physiological, self-concept, role function and interdependence modes. Such an assessment helps to develop more effective programs to modify clients’ maladaptive behaviors (15).

QOL consists of both physiological and psychological aspects while RAM can comprehensively cover these aspects and produce positive outcomes for the elderly people (12). Therefore, using standard care delivery models such as RAM seems necessary. RAM is a safe, non-invasive, inexpensive, easily applicable non-pharmacological intervention to enhance individuals’ physical and psychological adaptation (13).

2. Objectives

The current study aimed to investigate the effect of an RAM-based care plan on nursing home residents’ QOL.

3. Methods

The study was conducted in 2013 by following a pretest-posttest controlled quasi-experimental design. The study population was the residents of the nursing homes located in Urmia, Iran. All 60 eligible elderly people were conveniently recruited. They were included if they were 60 years old or more (1), oriented to time, place and person, did not receive psychotherapy or experience the loss of close relatives during the last six months before the study, did not receive treatments which could affect mental abilities, memory, or thinking, and did not have hearing or speech impairment, debilitating conditions, and physical disorders which could affect mental health (such as thyroid disorders). On the other hand, those participants who experienced any significant negative event or death were excluded from the study. After obtaining a written informed consent from the subjects, they were randomly allocated to an experimental or a control group using randomization software.

A demographic questionnaire and the Persian version of the short-form 36-item QOL questionnaire (SF-36) were employed for data collection (11). The questionnaires were completed for the participants through the interview technique. The SF-36 is a valid and reliable questionnaire which contains 36 questions and assesses QOL in eight domains including physical functioning, role performance, bodily pain, general health perception, vitality, social functioning, emotional functioning and mental health. Three-, five- and six-choice questions of the SF-36 are scored on three-, five-, and six-point scales of ‘0, 50 and 100’, ‘0, 25, 50, 75, and 100’, and ‘0, 20, 40, 60, 80, and 100’, respectively. Therefore, the total score of each domain ranges from 0 to 100, the higher the score the better the QOL. The validity and the reliability of the SF-36 were evaluated in different studies. For example, Heidari and Shahbazi found that the Cronbach’s alpha and the test-retest correlation coefficient of the survey were 0.83 and 0.87, respectively (16). Hamidizadeh et al. also confirmed the content validity of the SF-36 and reported a test-retest correlation coefficient of 0.87 (17). Montazeri et al. also noted that the SF-36 had an acceptable validity and reliability (18).

To design the study intervention, authors initially assessed and identified each participant’s physiological, self-concept, role function and interdependence maladaptive behaviors and their focal, contextual and residual stimuli through the standardized RAM-based assessment forms. The forms were completed by holding personal interviews with each participant. Then, a unique four-session care plan was developed and implemented for each participant based on his/her maladaptive behaviors and their focal, contextual and residual stimuli. The plans aimed to modify unhealthy and maladaptive behaviors and turn them into healthy and adaptive ones. Besides these four-session individual care plans, two educational sessions were held for all participants to address their joint maladaptive behaviors. For instance, educations in the area of physiological behaviors were about proper nutrition, adequate and balanced physical activity, factors affecting sleep, etc. Regarding the self-concept mode, educations were provided to make positive changes in the participants’ self-image and ideal image. In the interdependence mode, educations were mainly about peer relations and participation in group discussions and religious rituals. Finally, educations in role function mode included materials such as assuming some responsibilities in nursing homes, participating in their birthday or wedding parties and organizing and joining sport teams. To prevent information leakage from the participants in the experimental group to their counterparts in the control group, the administrators of the nursing homes settled them in separate rooms.

In the four-session personal programs, it was attempted to manipulate the focal, contextual and residual stimuli of each individual participant’s physiological, self-concept, role function and interdependence maladaptive behaviors. For instance, a participant with muscular weakness (a physiological problem) due to limited mobility (the focal stimulus) was encouraged to do physical exercise and walk. Besides, such participants were accompanied in their physical exercises. On the other hand, a participant with constipation (a physiological problem) due to limited intake of fluids and high-fiber foods (the focal stimuli) and decreased physical activity (the contextual stimulus), was provided with fruits, vegetables and fluids and was asked to perform physical activity. Finally, the elderly participants with role function and interdependence-related maladaptive behaviors were provided with counseling services by a psychologist.

During the first one month period after implementing the intervention, authors referred to the study setting and supervised the participants’ engagement in behavior modification activities. At the end of this one-month follow-up period, the participants were asked to re-complete the SF-36. For the sake of ethical considerations, the care plans were provided to the administrators and the staffs of the study setting and they were asked to use them for the participants in the control group.

One participant from the experimental group died during the study and thus, the number of elderly people in this group reduced to 29. The study data were transferred into the SPSS software. The descriptive statistics was used to present the data while the Chi-square and the paired- and the independent-sample T-tests were employed for data analysis. P-values less than 0.05 were considered as significant.

4. Results

The independent-sample T-test and the Chi-square test showed insignificant differences between the experimental and the control groups respecting the participants’ age, length of stay in nursing homes, number of children, gender, marital and educational status, source of income and insurance coverage (Table 1).

The results of the study also revealed that the groups did not differ significantly concerning the pretest mean scores of physical functioning, role performance, bodily pain, general health perception, vitality, social functioning, emotional functioning and mental health as well as total QOL mean score (P > 0.05). However, in the posttest, the differences between the groups regarding all these variables were statistically significant (P < 0.05; Table 2).

The pretest and the posttest mean scores of QOL in the control group were 43.49 and 43.69, respectively. In the experimental group, the pretest QOL mean score was 46.36 which increased to 67.59 after the study intervention. The paired-sample T-test results indicated that pretest-posttest difference in the score of QOL in the control group was not statistically significant (P = 0.354), while it was significant in the experimental group (P < 0.001) (Table 3).

5. Discussion

One of the challenges of the 21st century is to promote people’s independence, self-control and adaptation to new life situations. Achieving these goals necessitates developing and implementing care plans based on RAM (14).

The study findings showed that the participants’ QOL was moderate to low and the study groups did not differ significantly in terms of the pretest mean scores of QOL. QOL is the difference between humans’ expectations and realities; the smaller the difference, the higher the QOL. Therefore, QOL is totally a personal matter which is based on individuals’ own perceptions of the different aspects of their lives; hence, it cannot be directly observed by others (19). Chan et al. reported that the most significant predictor of QOL was health, undermined by age (9). Osada also noted that elderly people who were able to do physical, recreational, leisure-time and daily life activities experienced lower levels of depression and had higher QOL (20). Subasi and Hayran found that elderly people with adequate leisure time and greater ability to perform activities of daily life were more satisfied with their lives. They also reported that educational and marital statuses, as well as leisure-time activities, significantly affect QOL (21).

The study findings also revealed the positive effects of the implemented RAM-based care program on elderly people’s QOL. QOL consists of physical, psychological and social domains. On the other hand, RAM also considers human as a comprehensive existence that has physical, psychological and social aspects (14). Consequently, RAM-based programs are usually comprehensive enough, cover humans’ different existential aspects and positively affect QOL. In agreement with the current study findings, Bakan and Akyol implemented RAM-based care program for patients with heart failure and found that it significantly improved their adaptations in the four main modes of physiological, self-concept, role function and interdependence (22). Besides, Rogers et al. reported the positive effects of physical activity on elderly people’s physiological adaptation. Nonetheless, they found that physical activity was not effective in promoting self-concept adaptation (12). The results of a study conducted in Iran by Sadeghnezhad et al. also illustrated that a ten-session RAM-based educational program with a one-month follow-up period significantly promoted psychological adaptation of patients with diabetes mellitus (23).

The findings of the present study also revealed that the implemented RAM-based care program significantly improved the scores of the different domains of QOL including physical functioning, role performance, bodily pain, general health perception, vitality, social functioning, emotional functioning and mental health. The strongest effect of the intervention was on elderly people’s bodily pain domain of QOL, denoting significant decrease in the participants’ problems in the area of bodily pain. This finding can be attributed to the effectiveness of the study intervention in boosting the participants’ physical strength and stimulating their desire to do more intense physical activities. On the other hand, the increase in the score of the psychological domain of QOL was smaller than those of the other domains. This finding is probably due to the closed environment of nursing homes as well as nursing home residents’ separation from their families. In line with the current study findings, Li et al. found that percutaneous coronary intervention was more effective than medication therapy to improve the scores of the physical functioning, bodily pain, physical role performance and general health domains of QOL among elderly people with acute coronary syndrome (24). Shyu et al. also reported that their interdisciplinary intervention significantly increased the scores of the physical domains of QOL among the elderly patients who had undergone a hip-fracture surgery (25). Imayama et al. compared the effects of dietary weight loss and exercise interventions on QOL in females with overweight and obesity. They found that dietary weight loss intervention was as effective as exercise intervention to improve the scores of the physical domains of QOL while combined dietary weight loss and exercise interventions produced more significant effects (26). In addition, Yu et al. indicated the efficiency of vitrectomy on the improvement of different aspects of QOL (including physical functioning, role performance, general health, social functioning, emotional functioning and psychological health) among patients with diabetic retinopathy (27). Dickson et al. a based on a study in New York reported that the self-care program and exercise-based intervention, as well as elderly people’s engagement in work-related activities, significantly enhanced physical and total QOL (28). The results of studies conducted in Iran also showed that elderly people’s QOL can be significantly improved through administrating educational interventions (26), group physical activity programs (17) and self-care programs (7, 29).

Families had a significant role in providing care to elderly people and patients with chronic illnesses. Unfortunately, the physical distance between families and nursing homes deprives nursing home residents from their families’ kindness, intimacy and support; hence, it can negatively affect their QOL.

5.1. Conclusions

According to the findings of the study, RAM-based care programs can improve QOL among elderly residents of nursing homes. Care plans and programs developed based on RAM and elderly people’s needs can encourage elderly people’s participation in healthy behaviors, promote their adaptation to aging and produce positive QOL-related results.
