Knowledge and Attitude about Mental Illness of Students in a University in Southern Nigeria

Objective: To ascertain the knowledge about mental illness and attitude of undergraduate students in a university in southern Nigeria, towards the mentally ill. Methods: This descriptive cross-sectional study was conducted at a Catholic University in Nigeria over a three-month period. 215 subjects were selected randomly from the total student population of 5045. A questionnaire containing socio-demographic variables and three subscales: The Knowledge about mental illness scale, Attitude to mental illness scale, Social Distance scale was administered to each subject. The data was analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0. Results: Males (62.3%), Christians (91.2%), Igbos (49.5%) and Single (93.0%) constituted the largest proportions of the subjects. A majority of the subjects supported some of the common inaccurate stereotypes about mental illness. They exhibited obvious gap in knowledge with respect to symptoms of specific mental disorder. 42.8% were not sure of the biological cause of mental illness. Even though 80% of the subjects agreed that those suffering from mental illness should be helped, 48.8% maintained that they have little in common with them. Only 33% were willing to make friends with someone with a mental illness. Conclusion: Better ways of educating the youths to dissolve deeply entrenched negative cognitions about mental illness should be given premium attention by all stakeholders, especially in Africa.

gy and outcome of mental disorders by the general public has led to poor attitude towards the mentally ill from time immemorial. This is because many people believe that mentally ill persons are dangerous, unpredictable and are less likely to be productive members of the community [1] [2]. These negative cognitions remain in spite of scientific breakthroughs that have helped us understand mental disorders better [3] [4].
It is worth noting that these negative attitudes and misperceptions are as old as mankind and are deeply entrenched from childhood through cultural myths and superstitions imbibed from the cradle. Stigmatization, rejection, ostracism, hostility and violence towards the mentally ill with attendant danger to the self esteem of the sufferers are some of the deleterious consequence of this unfortunate situation [5] [6]. History is replete with accounts of many unfortunate mentally ill perhaps labeled as witches, harassed, accused of causing pestilences and ill luck and some have faced gruesome execution [7] [8].
Many studies have been carried out in the developed world to assess the knowledge and attitude of the general public towards those suffering from mental illness [9] [10]. A few of such studies have been carried out in sub-Saharan Africa especially in the Western Nigeria [11] [12] and their results indicate that stigmatization of the mentally ill in a common phenomenon. Nevertheless there is paucity of such studies in the Niger Delta region of Nigeria. It is expected that availability of empirical data on this burning issue in the Niger Delta region will help in re-strategizing our advocacy initiatives for the mentally ill and will translate to a more effective anti-stigmatization campaign in the region.

Methodology
This descriptive cross-sectional study was conducted at the Madonna University Elele, Rivers State of Nigeria over a three month period from April-June 2016.
All the students of Madonna University Elele who were present in the school campus during the study period were included in the study. Those who were on an academic posting outside the school or those who were on holidays or ill were excluded to minimize the difficulty associated with the collection of completed questionnaires. Two hundred and fifteen (215) subjects were selected randomly from the total student population of 5045. These subjects consented to the study and hence had the research instruments administered to each of them.

Research Instruments
A standard questionnaire comprising demographic questions as well as scales adopted from previously published studies were utilized for this research. b) Attitude to mental illness Questionnaire (Wahl et al.) [1].
It contains 17 items opinion statement about mental illness to which the participants will also agree with or disagree in a 5-point Likert format.

c) Social Distance Questionnaire
This is an 11 item questionnaire to which the participants will also respond to in a Likert format. The subjects were asked to indicate their degree of willingness to interact with a person suffering from a mental illness in a specific social situation. This scale was adopted from the Modified Bogardus Social Distance Scale (MBSDS) developed by Link [3] to better fit the lives of undergraduate students.

Results
A total of 215 subjects participated and completed the study. and "strongly agree" responses. The percentage reported as expressing disagreement comprise "disagree" and "strongly disagree" responses. Similarly, for the social distance "willingness" include "definitely willing" and "probably willing" responses; and "unwillingness" includes the "definitely unwilling" and "probably unwilling" responses.  It is also noteworthy that 53.5% of the subjects insisted that students with C. D. Chukwujekwu Journal of Biosciences and Medicines  Table 4 summarizes responses to social distance item. About half of the respondents (52.5%) expressed a willingness to talk to someone with mental illness while only 33% were willing to make friends with someone with a mental illness. Only 16.8% were willing to have someone with mental illness as a neighbor, 22.3% were probably willing to sit next to someone with mental illness, 17.7% were willing to invite someone with a mental illness to their home. Only 7.9% Journal of Biosciences and Medicines

Discussion
The results for this study show that the students' knowledge about mental illness is apparently deficient. Even though a greater proportion is aware that mental illness is portrayed negatively by the media, majority of the students disappointingly endorse the common inaccurate stereotypes attributed to people with C. D. Chukwujekwu  It is also important to point out that the students demonstrated lack of knowledge about the symptoms of specific mental disorder. Only 9.3% disagreed with the misconception that schizophrenia involves multiple personalities and 40.9% were unsure if overly energetic behavior is characteristic of Bipolar disorder. Similarly, 42.8% were not sure if mental illness has a biological cause. These findings are similar to result from previous studies [9] [10] [11] [12].
In the light of the foregoing, the need to educate students to recognize specific mental disorders and hence be able respond to them appropriately is required.
However it is quite commendable that most of the students agreed that the use of pharmacotherapy is a useful way to treat mental illness. This is not surprising considering that there has been a greater shift from psychological to biological activity as management of mental disorders since half a century ago [4].
Nevertheless, it is disappointing that in the 21 st century and after more than 100 yrs of organized psychiatry, and ground-breaking advances in the aetiology and treatment of mental disorders, the students still exhibit significant lack of knowledge about mental disorders. Their pessimism about the treatment and recovery from severe mental illness further underscore this lack of knowledge and emphasizes that more need to be done in terms of education to erase deeply ingrained cultural myths and misconception about mental illness.

C. D. Chukwujekwu
It is remarkable that the students' activities to a large extent were negative. This is at variance with report by Wahl et al. [1]. It is a paradox considering that more than 80% of the students agreed that mentally ill persons deserve respect and that more should be done to help them. Surprisingly, the wide range of negative attitude expressed by a significant proportion of the students is a source of concern. More than a third of the subjects are neither sure if they would be comfortable meeting a person with mental illness nor if a person with mental illness could be a good friend. This is less stigmatizing than the results reported by Gureje et al. in a similar study carried out in which 96% of the subjects believed that people suffering from mental illness are dangerous and 82% maintained that they were afraid to have a conversation with a mentally ill patient [11]. A greater proportion subscribes to isolating the mentally ill to keep the community safer and that students with mental illness should not be in regular classes. They maintained that it would be embarrassing to have a mental illness and a significant proportion stated that they had little in common with people suffering from mental illness. These findings reflect the societal view about mental illness. It is not surprising considering the deficient knowledge and misconception about mental illness already expressed by the respondents. It is obvious that deficient and inadequate knowledge fuels stigma and prejudices. These in turn translate to the strong degree of social distance expressed towards the mentally ill by the students. More than half of the students were unwilling to talk to someone with mental illness. Only one third were willing to befriend someone with mental illness and less than a quarter would be willing to sit next to someone with mental illness. Less than a fifth were willing to have someone with mental illness as a neighbor or invite him to their home. Less than 10% were willing to work in a class project with someone suffering from mental illness or date such a person. These findings clearly indicate that the more intimate the relationship the less willing people are to relate with them. This corroborates previous results by Gureje et al. where only 16.9% of the respondents would ever consider marrying a mentally ill individual [11] while 41% of mentally ill patients reported that they experienced harassments of one form or the other according to Berzins et al. [7]. This unfortunate narrative concerning the mentally ill which is in keeping with the results of this study confirms the findings of Shibre et al. who reported that 75% of respondents perceived they were stigmatized because they were related to someone who was mentally ill, 42% maintained that they were being treated with difficulty and 37% confessed that they would prefer to conceal their family history of mental illness [12]. This underlies the substantial rejection these patients still suffer in the 21 st century.
Considering that the study was carried out in a Catholic University, in Nigeria, it is disheartening that in spite of several decades of western education and emphasis on religious morals, the mentally ill still suffers so much rejection. If the students who are supposedly enlightened react this way towards the mentally ill, one can only imagine the degree of rejection the mentally ill suffer in the hands of the illiterate majority in our population. This underscores the enormity

Limitations
This study was carried out in a Catholic University. It is possible that religious dogmas may have played a role in the views and attitude of the respondents towards mental illness. Therefore its application to the general population should be done with caution.

Conclusion
The study attempts to objectively assess young people's knowledge and attitude about mental illness. Results show that the knowledge young people have about mental illness is clearly deficient. Their lack of understanding of the nature and symptoms of mental illness make them unable to recognize these disorders appropriately and hence proffer help. Furthermore, attitudes expressed towards the social acceptance of peers with mental illness were substantially negative. This in turn fuels self stigma by the sufferers. Better ways of educating the youths to dissolve deeply entrenched negative cognitions about mental illness should be given premium attention by all stakeholders. This will be the only hope to see a future generation with the right attitude towards the mentally ill and hence translate to better management and outcome for the mentally ill.
