    Objective: Environmental psychology as a science could be useful in

    understanding the dissociation between the man and the environment. The aim of this study was to compare mental health, job satisfaction and well-being of nurses who work in hospital environments with different designs. Material: This was a quasi-experimental study, in which 250 nurses filled

    out the mental health, well-being and job satisfaction questionnaires. They were categorized into 3 groups randomly. Group1 included 63 nurses who worked in an environment without any natural elements; group 2 included 100 nurses who worked in an environment with natural elements and group 3 included 87 nurses who worked in an environment without any psychological and ergonomic design. The last group was only stimulated by demonstrating visual stimulus. Data were analyzed using the ANOVA and Tukey’s pursuit statistical method. Results: The nurses who were working in an environment without any

    natural elements reported significantly lower scores on mental health, well-being and job satisfaction compared to those who were working in other groups, with the exception of social functioning . Moreover, depression and anxiety were more common in nurses who were working in environments without any natural elements compared to those in the other groups (p<0.05). Conclusions: We can increase job satisfaction, and mental health and

    well-being of the nurses through the use of natural design and environmental psychology indexes in hospital buildings.

    Today, Urbanization and separation of humans from nature have caused enormous damages to

    human beings. Influx to the cities and lack of space

    caused the loss of natural spaces which is one of the

    most important stressful factors for humans (1).

    Researches have shown that lack of each person’s

    control over the environment and existence of

    problems in design-engineering system of the

    buildings caused congestion and social isolation

    which ultimately have led to some problems

    regarding job and social features; and consequently,

    these factors endanger the mental health of the

    individuals (2).According to the World Health

    Organization (WHO), the full ability to take social,

    psychological and physical roles is called health.

    Patient’s environment can play a crucial role in

    improving the therapeutic efficacy as well as patient-

    reported outcomes (3). Environmental psychology as

    a science could be useful in understanding the

    dissociation between the

    man and the environment (4), and it indicates that

    how location specification affect behavior and helps

    the behavior change and causes compatibility with

    the environment (5). In broken window theory, Wilson et al. (1982)

    showed that environment has powerful impacts on

    human health and wellbeing (6). Personal wellbeing

    shows individuals’ satisfaction and happiness about

    their life quality and is a positive status of physical,

    psychological and social welfare (7-8). One of the

    aspects of environment that may affect human health

    is Building Environment (BE). Conceptually,

    Building Environment includes all of constructed

    environments in which humans live and work (9),

    and it also includes building design and interior

    architecture and effects human’s emotions,

    excitement and performance (10).

    Nursing is one of the stressful professions. Working

    pressure, by itself, is considered a source of

    frustration for nurses. Nurses are the man power

    inside the hospitals and are the main service

    providers in the health care system and they

    significantly affect the health and hygiene level of

    the society by providing various health related

    services to the patients (11). Nurses are always

    exposed to the damages caused by stress, working

    environment and activities related to their job (12).

    Gelman and Turner in an article about nurses’ quality

    of life have found that hospital environment directly

    affects individual's quality of life (13).

    One of the issues raised in nursing services

    management is the low level or lack of job

    satisfaction. Reduced attention quality, leaving work

    and absence from work are some of the negative

    effects of low job satisfaction. (14). Lack of job

    satisfaction is one of the important factors in nurses

    quitting their job (15). Job satisfaction is an

    underlying attitude to create tendency, interest, talent

    and preparation in order to give proper response to

    the working environment in personal and social

    features and includes the features and requirements

    of a job with external environment and interpersonal

    relations with working situation (16). Psychologists

    also believe that environment ergonomics and design

    may reduce physical and mental stressors and

    pressures inside the working environment (17) . Using the environmental psychology principles in

    location designs (especially due to the treatment of

    environment which is discussed in the holistic

    medicine) promotes mental health and wellbeing

    (18). Watching the nature from a window increases

    the sense of wellbeing (19); also, using natural

    elements in the work environment results in the

    following positive outcomes: Reducing the

    environmental stress and increasing calmness (18),

    less depression and more mental compatibility (20),

    positive effects on happiness and quality of life (21),

    acting as a buffer against the stressful events (22),

    improving individual health (23), increasing the

    compatibility, having a sense of safety, experiencing

    positive emotion, reducing angriness and increasing

    patience (24) . Therefore, this research compares mental health, job

    satisfaction and wellbeing of nurses depending on

    their working environment . The hypothesis of this research was that the indexes

    of job satisfaction, wellbeing, mental health and their

    subscales (somatic symptoms, anxiety and insomnia,

    social dysfunction and severe depression) were

    different in the three groups of the nurses who

    worked in three different work environments: the

    nurses who worked in an environment with no

    interior design (1), nurses who worked in an

    environment with natural beautiful perspective, (2)

    and those nurses who worked in an environment with

    no interior design, but with limited view of the

    simulated garden (3).

    Material and Methods

    This was a quasi-experimental study. The sample

    included 250 male and female nurses with the age

    range of 23- 47 years who were randomly selected

    from Khatamol-Al-Anbia hospital located in the third

    district of Tehran municipality. This sample was substituted stochastically in 3 groups randomly. The first group of the nurses (n =

    63) worked in the basement of the hospital where the

    design was not in accordance with the psychological-

    environmental principles, and the nurses who worked

    there experienced an ordinary and cold environment

    and they had no access to the designed environment;

    the second group ( n = 100) worked in a small garden

    simulated area which had been designed based on

    psychological principles (25, 26) and the third group

    ( n= 87) worked in an area, from which they could

    see the outside designed environment through a

    distant window. The sampling has been done in two

    shifts of morning and afternoon. All participants

    were asked to complete the anxiety and depression

    questionnaire at baseline . Job situation and working volume and salary were

    equal in all the participants, and we tried to remove

    all the interruptive factors . Sample size was calculated based on a previous study. A hypothesized mean which was considered

    for this study was 4.96 for job satisfaction in the

    control group (SD51.09). Power-calculations to

    detect small effects (12%) on scores of job

    satisfaction changes with a power of 0.80 (p < 0.05)

    resulted in a target sample size of 50 for each group

    (27)

    This garden simulated location was designed based

    on environmental psychology using known natural

    elements in an environment covered by plants and

    green elements with a combination of jungle outlook

    and canebrake with a short waterfall and gentle

    sound of the birds; also, there were some comfortable

    chairs made of bamboo wood for the resting time of

    the nurses below a canopy (Fig 1). The garden

    simulated location could be seen from all parts of this

    section; and when windows were opened, the nurses

    could hear the sound of the waterfall and birds during

    their work.

    During the break time, the nurses could use the

    resting area inside the garden simulated area. At the

    same floor of the hospital after leaving this section at

    the end of opposite corridor, there was an area where the nurses could only look at the garden simulated

    location from a far distance and there was no access

    Tavakkoli, Asaadi, Pakpour, et al

    Iranian J Psychiatry 10:3, Jun 2015 ijps.tums.ac.ir 160

    to the garden (Fig 2). At the same hospital, there

    were some areas in the basement floor where there

    were no environmental factors with a in a quiet dimly

    lit room even there were no windows. In other words,

    the hard and cold environment of the hospital cannot

    be seen well enough.

    General Health Questionnaire (GHQ): The

    questionnaire of general health arbitrated to Goldberg&

    Hillier for screening the non-psychotic mental

    disorders has been designed with 28 questions on a 4-

    point Likert- scale and 4 subscales about somatic

    symptoms, anxiety and insomnia, social dysfunction

    and severe depression (29,28). This tool has been

    translated into Persian and was found to be highly valid

    and reliable (30). Job Satisfaction Index (JSI): The Job Satisfaction Index

    (JSI) which has been made by Smith and Kendal

    (1996) is a scale with 20 items which is scored on a 5-

    point Likert scale. Smith and Kendal believe that this

    scale has high reliability and validity. They have

    reported the reliability coefficient of the sub tests in the

    first study from 59% to 93% and in the second study

    from 62% to 93%. (31) Haghayegh Khorasani reported

    the reliability coefficients of the subtests as 0.59-0.92

    in the first study and 0.62-0.93 in the second study in

    Iran (32). In the present study, reliability of JSI was

    obtained 83% by Cronbach's α and content validity was

    approved by the faculty . Personal wellbeing questionnaire: The personal

    wellbeing questionnaire of adults named “Personal

    Wellbeing Index” has been standardized in 2002. The

    current scale has 8 items, each of which asks questions

    about one field on a 7- point likert- scale. Aghayousefi

    (2004) has found the reliability of the research to be

    0.84 and in another research by using Cronbach's α;

    also, he has found the reliability of the test equal to

    0.87 (33). The current research has been performed three months

    after designing the hospital environment. Then, some

    nurses used that simulated garden, some looked at the

    simulated garden from a far distance and the others

    were located in the basement with no environmental

    psychology. In this research, the indexes of mental

    health, job satisfaction and wellbeing of the nurses

    working in this hospital have been compared

    considering the equality of all working situations and

    only based on the differences between working

    environment indexes. The findings were entered to

    SPSS- 17 and have been analyzed by Variance

    Analysis method and then by Tukey’s pursuit method.

    Results

    The study participants consist of were 250 nurses,

    (62 men and 188 women); Of whom, 100 were

    married and 150 were single. All participants had

    tertiary education. There was not any significant

    difference between the groups in terms of anxiety

    and depression at baseline (P>0.05). We used variance analysis to The findings related to compare

    and survey the differences among the means of the

    three groups in the general health index, job

    satisfaction and wellbeing.

    As depicted in Table 1, significant differences

    between the three groups were found. Nurses who

    were working in an environment with interior design

    reported significantly higher general health compared

    than those working in an environment with no

    interior design (Table 1). Considering the current

    results, at significance level of p<0.05, the general

    health of the nurses working in a garden simulated

    area and the nurses who only viewed the

    environment from the window was different from the

    nurses working in an environment with no design.

    Moreover, considering the results of the Tukey test,

    it can be stated that at the same level of significance,

    the general health of the nurses working in a garden

    simulated environment and the nurses who looked at

    the environment from a window was better than the

    nurses who are worked in an area without any

    designs . As demonstrated in Table 2, the comparison among

    the sub scales of the general health shows that the

    anxiety of those nurses working in the garden

    simulated area and the nurses who looked at the

    garden simulated area from a window were

    significantly less than the nurses working in the area

    without any designs (p<0.05). On the other hand,

    depression of the nurses working in the garden

    simulated setting and the nurses looking at the

    garden simulated location from a window was less

    than the first group. No significant difference was

    found between the three groups in respect to the

    social function subscale.

    As shown in table 3, the difference among the three

    groups was statistically significant on job

    satisfaction, and the mean of job satisfaction of the

    second group is was higher than the third and the

    first groups; also, the mean of job satisfaction of the

    second group was higher than the third group.

    Considering the results of variance analysis and Tukey pursuit test, it can be said that the job

    satisfaction of in the second group (those working in

    a simulated area) was higher than of the third group

    (those who were working in an area having access to

    the designed area via a window) at significance level

    of 0.01. Furthermore, considering Tukey’s analysis,

    it can be said that job satisfaction level of the nurses

    working in a garden simulated area and nurses

    working in the area with windows was significantly

    more than those nurses working in the area with no

    design. As shown in Table 4, the mean of wellbeing index on

    the nurses working in a garden simulated area was

    higher than the mean of wellbeing index of the

    nurses working in the area without design with a

    small difference comparing compared to the nurses

    looking at the designed area from a window .

    Considering the current results, the wellbeing of the

    nurses working in a garden simulated area was

    different from that of the nurses who looked at the

    area from a window (p<0.05). Moreover, considering

    Tukey’s pursuit test, it can be stated that at the same

    significance level, the wellbeing of the nurses

    working in the designed area was higher than that of

    the nurses who worked in the area with no design

    with a small difference compared to those looking at

    the area from a window. There was no any

    significant differences between nurses who were

    working in the garden simulated area and those

    looking at the area from a window.

    Discussion

    The analysis of this research data revealed that the

    mental health of the nurses working in the garden

    simulated area and those working in the area with a

    window to a designed area was better than those

    working in the area with no design. Also, the results

    revealed a difference between the stress of the nurses

    working in a no- design area and the nurses working in

    the designed area and those looking at the designed

    area from a window. This result is in accordance with

    that of previous findings (20, 24).

    We usually live in a place without realizing its effects

    on ourselves. Development of the cities and their extra

    ordinary growth had forced the architects to build the

    buildings in a vertical direction instead of horizontal

    and there is no exception about the hospitals; and this

    has led to the vertical growth of the hospitals and also

    caused a distance from the nature .

    This research revealed a difference between

    depressions of the nurses working in the area with no

    design and those working in the designed area or those

    looking at the area from a window; the findings were in

    line with researches by Perrins et al. and Evans (21,

    18). Also, there was no difference between the social

    performances of the nurses working in the designed

    area, those working in the area with a window to the

    designed area and also those working in the area with

    no design .

    The findings of this research showed that this simulated

    garden area improved the job satisfaction and the

    marks of job satisfaction of the nurses working at the

    designed area and those with a view to the designed

    area. These findings are in accordance with the

    findings by Walsh and Knott, Moos and Insel, Hoseini

    and Mirzabeigi (16, 17, 14, 15) .

    The other findings of this research showed that the

    designed area for the resting time of the nurses affected

    their wellbeing and that the marks of nurses’ wellbeing

    were higher in the group working in the designed area

    and those working in the area with a window in

    comparison with those working in the area with no

    natural environment. These findings are in accordance

    with the previous findings that showed being at a

    designed area reduces stress or mental fatigue

    (psychologically), and improves physical health and

    develops wellbeing (increasing social interactions and

    reducing panic) (13, 17,11). Also, these findings

    support Park’s research that showed principles of

    environment design affect stress and well-being (34).

    Green areas in cities have been rescued significantly.

    On the other hands, the numbers of buildings have been

    increased considerably in cities. Therefore, designers

    and architects should closely follow the environmental

    psychologists in order to improve the human

    environment. Applying basic changes in the

    environment based on environmental psychology

    indexes, positively affects the health of the nurses. This

    study revealed that wellbeing, job satisfaction and

    mental health were significantly higher in the nurses

    who were working in the area with no design but

    watching the designed area from a window are not less

    than those working in the area designed with natural

    factors. This study indicated that places which were

    designed by natural elements increase worker’s mental

    health, job satisfaction as well as their wellbeing .

    Environmental Effects on Mental Health Job Satisfaction

    Iranian J Psychiatry 10:3, Jun 2015 ijps.tums.ac.ir 163

    The studies conducted on the effects of different

    environments on different psychological indexes are

    rare and it is suggested that the survey on other

    variables such as nurses’ quality of life with different

    intervals after the design be conducted in the future

    studies. The main limitation of this study was the lack

    of a proper hospital design based on psychological

    principles; consequently, we could not conduct an

    experimental study.

    Limitations

    This study has a limitation as follow: the study sample

    had been selected from only one hospital, thus, it

    limited the generalizability of the study results.

    Conclusion

    By applying the environmental indexes in buildings,

    we can reduce the coefficient of the hardness and

    increase the environment psychological indexes.

    Because nursing is one of the most important positions

    in the society and the health of the nurses affects the

    general health of the patients, we should improve their

    mental health, job satisfaction and wellbeing through

    the use of environmental psychology.
