Depression, Quality of Life and Participation Level of People with Post-Hansen’s Disease Living in Selected States in SouthEast, Nigeria.
Background: Hansen’s disease is a disease that causes not only physical problem but also psychological and social problems. Too much emphasis on medical care can lead to neglect in the holistic rehabilitation of post-Hansen’s disease persons. Aim: This study was carried out to assess the level of depression, quality of life and participation level of post-Hansen’s disease persons living in South-East Nigeria. Methods: A cross-sectional survey was conducted among the post-Hansen’s disease persons using the Major Depression Inventory for level of depression, SF-12 Health Survey for quality of life, and Participation Scale for participation level. The obtained data was summarized using descriptive statistics of frequency distribution tables and charts, mean and standard deviation, and analyzed using inferential statistics of Spearman’s rank correlation and Chi-square test. Alpha level was set at 0.05. Results: A total of 99 persons (51 males, 48 females) within 22-88 years participated in this study. The results of this study showed that majority of the participants were severely depressed (79.8%), majority had poor quality of life (57.6%), and majority were moderately restricted in participation (56.6%). There was no significant correlation among the level of depression, quality of life and participation level. Age and gender did not significantly influence their level of depression, quality of life and participation level (p>0.05). Conclusion: The outcome of this study showed that majority of post-Hansen’s disease persons living in South-East Nigeria are depressed with a poor quality of life.There is a need to implement measures that would improve the psychosocial and socio-economic rehabilitation services for post-Hansen’s disease persons.
Background of Study
Hansen’s disease, also known as leprosy, is one of the oldest disabling diseases known to man [1]. It is a chronic granulomatous disease caused by Mycobacterium leprae (an acid fast, rod-shaped bacillus) principally affecting the peripheral nerves, mucosa of the respiratory tract and skin of human beings [2]. The bacterium was first identified in 1873 by the Norwegian physician, Gerhard HenrickArmauer Hansen, hence the name of the disease [3]. There is a high degree of misunderstanding and misconceptions about the cause, methods of transmission, and treatment [4]. In endemic areas, the majority of individuals infected with mycobacterium leprae do not develop the disease, and it is believed that the disease development is associated with close and prolonged contact with untreated people with multibacillary disease [5]. Since the inception of multi-drug therapy (MDT) in 1982, there has been at least 85% reduction in global prevalence of Hansen’s disease [6]. Hence, Hansen’s disease is no longer the dreaded disease it used to be and its sufferers face a far better future than rejection and exclusion from the society [7]. However, the social image of Hansen’s disease is not greatly changed in many parts of the world; this is all too well reflected in the attitude of the community, particularly towards individuals disabled due to the disease.
Leprosy has a great probability of causing a permanent and progressive physical disability if left untreated [8]. These impairments and disabilities cause stigma and discrimination among the leprosy affected patients [9]. The stigma when internalized anticipated or experienced in the society leads to depression [9]. These negative social attitudes towards Hansen’s disease can cause more distress to patients and their relatives than the disease itself, as it unnecessarily exposes the sufferers to risks and adds a social and economic burden to the physical burden of the illness [10]. The patients tend to lack in their aspirations because of the depression and the feeling of hopelessness and loss of self-actualization.
Depression is a mood disorder characterized by persistently low mood and a feeling of sadness and loss of interest [11]. Depression is a common illness worldwide with more than 300 million people affected, and at its worst, can lead to suicide [12]. Some forms of depression are slightly different, or they may develop under unique Ibikunle PO, et al. Depression, Quality of Life and Participation Level of People with Post-Hansen’s Disease Living in Selected States in South-East, Nigeria. Clin Dermatol J 2019, 4(1): 000173.
circumstances, such as: Persistent depressive disorder (also called dysthymia), postpartum depression, psychotic depression, seasonal affective disorder, bipolar disorder, disruptive mood dysregulation disorder and premenstrual dysphoric disorder (PMDD) (National Institute of Mental Health [13]. Depression is said to be the most common psychiatric disorder among people with leprosy [14]. In some societies in Nigeria, people with leprosy are completely banished from the community. People with leprosy living in isolated camps are at greater risk of depression because they have been displaced from their place of abode as a result of their desire to stay away from people because of the embarrassment they experience or due to outright rejection by those they normally live with because of the perceived infectivity of the illness [14].
World Health Organization (WHO) defines Quality of Life 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 [15]. It is a broad ranging concept affected in a complex way by the person’s physical health, psychological state, level of independence, social relationships, personal beliefs and their relationship to salient features of their environment [15]. Leprosy has an impact on patients’ quality of life [16]. Studies show that individuals affected by leprosy had low quality of life scores in the physical and psychological health domains [17]. Leprosy subjects are strongly affected not only by physical issues such as peripheral neuropathy but also by massive social exclusion that may be related to quality of life impairment [18]. A study revealed that factors potentially contributing to the deteriorated quality of life of leprosy patients were the presence of perceived stigma, fewer years of education, the presence of deformities, and a lower annual income [19]. Mekowulu [20] stated that the male participants’ quality of life was higher than those of the female participants. A study conducted in Ghana demonstrated low quality of life among the sampled elderly people affected by leprosy at the selected leprosoria, thus stressing the need for measures that could improve their health and socio-economic status within the settlements [16].
Participation is a person’s involvement in a life situation [21]. Participation restrictions are often Copyright© Ibikunle PO, et al.
considered 'social problems' and are often caused by impairment, activity limitation, self-stigmatization, disease-related money problems, absence of equipment, support/relationship, attitude and systems, environment, policies or law (WHO, 2001). In a study carried out in Oji River, Enugu State Nigeria, it was concluded that Post- Hansen’s disease persons had on the average, severe participation restriction [22]. During the testing phase in the development process of the Participation Scale, P- scores were shown to be significantly higher when physical impairment was observed [23, 24]. Addressing the issues of stigma and social reintegration and rehabilitation of persons affected by leprosy is an urgent need [25].
Leprosy is a disease that causes not only physical problem but also mental and social problems [26]. It was found that too much emphasis on medical care led to neglect of psycho-socio-economic rehabilitation with a resultant poor quality of life [27]. The lower the socio- economic status and the severe the level of deformity of the respondents, the extreme is the level of participation restriction among them [28]. The patients may experience withdrawal due to depression, loss of hope and lack of quota to the society or even suicidal tendencies. The aims of the study are:
- To determine the level of depression, quality of life and participation level among post-Hansen’s disease persons living in South-East Nigeria.
- To determine the relationship among the level of depression, quality of life and participation level among post-Hansen’s disease persons living in South-East Nigeria.
- To determine if age and gender will correlate with the level of depression, quality of life and participation level among post-Hansen’s disease persons living in South-East Nigeria.
Materials and Method
The research was a cross-sectional survey.
The population for this study comprised post-Hansen’s disease persons resident in the currently operational leprosy rehabilitation hospitals/centers in selected states in South-East Nigeria: The Leprosy settlement, Oji River, Enugu State and Leprosy home, Okija, Anambra State.
Participants of this study included post-Hansen’s disease persons who had completed the prescribed multidrug therapy and were residing in the currently Ibikunle PO, et al. Depression, Quality of Life and Participation Level of People with Post-Hansen’s Disease Living in Selected States in South-East, Nigeria. Clin Dermatol J 2019, 4(1): 000173.
operational leprosy rehabilitation hospitals/centers in selected states in South-East Nigeria. Participants that were excluded from this study included: i. Post-Hansen’s disease persons who are not well oriented in time, place and person. ii. Post-Hansen’s disease persons who had communication impairment.
A sample size of 99 had an 87% power to detect a medium effect size of 0.3 at alpha level of significance 0.05. Sample size was calculated using G* Power 3.0.10.
The centers for this study were purposively selected. In each center, each consenting participant was consecutively recruited.
Research Instruments
- Major Depression Inventory: Major Depression Inventory (MDI) is used to estimate the severity of depression among the participants. This is a 10-item scale. Each item is rated on a 6-point scale from 0 (at no time) to 5 (all of the time). Individual item scores are summed to provide the total score. Higher scores depict higher level of depression. MDI has a high content validity for measuring severity of depression, supported both with classical and modern psychometric tests [29]. The sensitivity of the MDI algorithms for major depression varied between 0.86 and 0.92; the specificity varied between 0.82 and 0.86; the Cronbach’s coefficient was 0.94 [30].
- SF-12: The SF-12 is a multipurpose short form survey with 12 questions, all selected from the SF-36 Health Survey. The questions were combined, scored and weighted to create two scales that provide glimpses into mental and physical functioning and overall health- related quality of life. Both Mental Component Summary Scores (MCS) and Physical Component Summary Scores (PCS) were shown to have high internal consistency reliability (alpha > 0.80). The Physical and Mental Health Composite Scores (PCS & MCS) are computed using the score of twelve questions and range from 0 to 100, where a zero score indicates the lower level of health measured by the scales and 100 indicates the highest level of health. The data obtained with the SF-12 has been developed, tested and validated by Quality Metric Incorporated [31].
• Participation scale: The Participation Scale (P- scale), developed in 2006, is a standardized tool used to quantify perceived participation restrictions. This Copyright© Ibikunle PO, et al.
instrument is based on the participation domains of the International Classification of Functioning, Disability and Health of the World Health Organization. P-scale is reliable and valid to measure client-perceived participation in people affected by leprosy or disability [32]. The 18-item instrument was developed in seven languages. Crohnbach’s alpha was 0.92, intra-tester stability 0.83 and inter-tester reliability 0.80 [32]. The Participation scale (Annex 1) is an 18-item interview- based instrument which covers eight out of nine major life domains which includes: learning and applying knowledge, communication, mobility, self-care, domestic life, interpersonal interactions, major life areas, and community, social and civic. The scale is pre-coded and the scores to each response are already assigned in the response boxes. The item score will each be between 0-5, while the sum score will be between 0-90. Individual item scores are summed to provide the total score [33]. The IGBO translation is a valid translation and is recommended for use among the Igbo-speaking group in Nigeria [34].
Procedure for Data Collection
Ethical approval was obtained from the Ethical Review Committee of Faculty of Health Sciences and Technology, College of Health Sciences, Nnamdi Azikiwe University, Nnewi before the commencement of the study.
A letter of introduction was collected from the Department of Medical Rehabilitation, College of Health Sciences, Nnamdi Azikiwe University, Nnewi Campus by the researchers, to introduce the researchers to the Heads of the leprosy centers requesting their consent to carry out the research.
The prospective participants were approached, the aim of the study was explained to them and they were encouraged to volunteer. The instruments were administered only to those who volunteered to participate in the study after obtaining their informed consent.
Data Analysis
The obtained data was summarized using descriptive statistics of frequency distribution tables, mean and standard deviation; while the inferential statistics of Spearman’s rho correlation test and Chi-square test were used to analyze the obtained data. Level of significance was set at 0.05.

This study was conducted with the aim of investigating the level of depression, quality of life and participation level of post-Hansen’s disease persons living in leprosy rehabilitation homes in selected states in South East, Nigeria. A total number of 99 (51 males, 48 females) post- Hansen’s disease persons within the age range of 22-88 years participated in the study.
Depression
The outcome of this study revealed that affected persons had severe depression. This concurs with the Ibikunle PO, et al. Depression, Quality of Life and Participation Level of People with Post-Hansen’s Disease Living in Selected States in South-East, Nigeria. Clin Dermatol J 2019, 4(1): 000173.
In this study, the female participants were severely depressed than the male counterparts. This aligns with the fact that in general population, depression and anxiety Copyright© Ibikunle PO, et al.
disorders are more frequent in women than in men [14, 35]. Several factors may increase a woman’s risk of depression; some of these are; coping with menstrual cycles, pregnancy, menopause, the prevalence of victimization of women and the tendency of women to ruminate over their problems [36, 37].
Although the participants in the age range of 40-49 had the highest score of depression, the age did not correlate with and was not associated with depression. A study revealed that age of the patients (young or old) was not significantly associated with both depression and anxiety disorder [14].
Quality of Life
The result of this study shows poor quality of life among the participants. This agrees with studies that show that individuals affected by leprosy had low quality of life scores in the physical and psychological health domains [17]. Pain is highly prevalent among leprosy patients and is associated with low quality of life [38]. Multiple regression analysis of a study revealed that factors potentially contributing to the deteriorated quality of life of leprosy patients were the presence of perceived stigma, fewer years of education, the presence of deformities, and a lower annual income [39].
The result of this study reveals that age did not correlate with, and was not associated with quality of life of post-Hansen’s disease persons. This agrees with the result of a recent study which reveals that age has no significant relationship on quality of life [16].
Gender of the participants did not correlate with the quality of life. However, the female participants had a higher quality of life score than the male participants. This agrees with a study which reveals that women had higher quality of life scores than men in almost every domain, and this perhaps implied a greater readiness among women to accept their situation, in line with their secondary role in the society [40]. However, recent studies reported a lower quality of life score in males than females affected by leprosy [16].
Participation Level
The findings of this study showed that there was moderate participation restriction among the participants. In South-east Nigeria, severe participation restrictions were found among post-Hansen’s disease persons [22].
Ibikunle PO, et al. Depression, Quality of Life and Participation Level of People with Post-Hansen’s Disease Living in Selected States in South-East, Nigeria. Clin Dermatol J 2019, 4(1): 000173.
Another study also revealed that leprosy affected patients had extreme participation restriction [19].
The findings of this study showed that there were no significant differences between gender and participation level of the participants. This concurs with a study conducted in India on the participation level of leprosy patients which revealed that there was no significant difference between gender and participation restriction level of the respondents [28]. This study shows a ratio of 29 males: 26 females (moderate participation restriction level) and 15males: 13 females (severe participation restriction level) among the participants. A gender-wise determination of the patients’ participation level revealed that males outnumbered females both in moderate and severe participation restriction level [28].
This study also shows that age of post-Hansen’s disease persons was not associated with their participation level. A study conducted by Ibikunle and Nwokeji [22] showed that age did not significantly influence the social participation of the affected persons. Another study shows that there was no significant association between age and participation level among patients in a Basic Health Unit (BHU) diagnosed with leprosy [41, 42, 43, 44].
Conclusion
From this study, it was concluded that:
- Post-Hansen’s disease persons in selected states in South-East Nigeria were severely depressed.
- The overall quality of life of post-Hansen’s disease persons in selected states in South-East Nigeria was poor.
- Post-Hansen’s disease persons in selected states in South-East Nigeria had moderate participation restriction.
- There was no significant correlation between level of depression, quality of life and participation level.
- Age did not significantly correlate with level of depression, quality of life and participation level.
- Gender was not significantly associated with level of depression, quality of life and participation level.
Recommendations
Based on this study, the following recommendations were proposed: 1. Further studies should be conducted across different regions in Nigeria on a larger population of post- Hansen’s disease persons.
Copyright© Ibikunle PO, et al.
2. Further studies should be done to compare the level of depression, quality of life and participation level of post-Hansen’s disease persons who dwell in rehabilitation homes and those who dwell outside the rehabilitation homes. 3. There is an urgent need to implement measures that would reduce the depression, improve the quality of life and participation level of post-Hansen’s disease persons. 4. There is also a need to improve the psycho-social and socio-economic rehabilitation services for post- Hansen’s disease persons.
