there are many different definitions for spirituality , but the following is provided by cook as a working definition : " spirituality is a distinctive , potentially creative and universal dimension of human experience arising both within the inner subjective awareness of individuals and within communities , social groups and traditions . it may be experienced as a relationship which is intimately inner , immanent and personal , within the self and others , and/or as relationship with that which is wholly other , transcendent and beyond the self . it is experienced as being of fundamental or ultimate importance and is thus concerned with matters of meaning and purpose in life , truth and values " ( 1 ) .
human beings are created of two physical and spiritual dimensions , and in the holistic care mechanism , both of the dimensions should be addressed ( 2 ) . the world health organization ( who ) definition of supportive care of patients with serious diseases answers the spiritual needs of these patients alongside physical and psychosocial needs ( 3 ) .
studies also have demonstrated that at least half of patients with chronic illnesses and their families need spiritual services . on the one hand
, there is a strong association between emotional and spiritual needs of patients , their general satisfaction of treatment , and the reduction of symptoms such as anxiety , pain , and depression ; on the other hand , it was seen that most health care providers were not educated enough in offering spiritual services ( 4 - 7 ) .
several questionnaires are available to assess spiritual needs , though they might have some shortcomings ( 8) .
first , the applied questionnaires mostly contain different religious purports and are not applicable to all communities .
second , they are considered a detailed part of a more general questionnaire about spiritual assessment . finally , the main interest of the questionnaire designers is in nursing rather than the medicine domain ( 9 ) .
therefore , to improve the precision of assessment , new questionnaires are being developed by different research groups .
knowing how these questionnaires are made , their strengths and weaknesses , and their theoretical bases can provide the groundwork for creating future questionnaires .
the purpose of this study was to collect comprehensive information about all of the scales that currently exist in this field .
therefore , this study may open a path for future research based on the present weaknesses .
an electronic search was performed with no limitations on time span ( until june 2015 ) or language in databases including pubmed , scopus , ovid , proquest and google scholar . in order to design the search order , first
, the word need and all its synonyms were selected from www.thesaurus.com as well as oxford and longman dictionaries . each of them was then searched in combination with derivations of the words spirit and religion in the title and keywords fields of articles . for example , the search query in pubmed was as follows : ( spirit*[title ] or religi*[ttitle ] ) and ( need*[title ] or wish*[title ] or obligat*[title ] or essenti*[title ] or requir*[title ] or demand*[title ] or want*[title ] or necess*[title ] or requisi*[title ] or intere*[title ] ) the titles and abstracts of the papers were studied by the authors of the present paper .
the criteria for selecting papers for the final report included : the existence of one search word in the title or keyword , needs recognition being mentioned as the main research objective in the abstract , and research leading to the generation of a new questionnaire .
the information was selected , and finally all the references of the selected papers were reviewed .
if they met the criteria , they were added to the selected papers in the following way : the keywords were reviewed , and new synonyms were added and searched again ( the final form is mentioned as above ) .
tables 1 and 2 lists the instruments and their psychometric properties in detail and table 3 displays their strong and weak points .

this scale was developed by galek et al . in 2005 in the usa and the three names spiritual need survey , spiritual need scale and patient spiritual needs assessment scale were applied for its introduction in different studies ( 9 - 11 ) .
this questionnaire had no special religious procedure and was based on the results of 12 qualitative , 7 quantitative , and 3 theoretical studies , using a systematic review method and had 29 yes / no questions originally ( 9 ) . in other studies , the developers modified the original tool and introduced the 28-item ( 10 ) and 24-item ( 11 ) versions of the questionnaire .
this questionnaire was designed by hermann in 2006 in the usa in a qualitative study on patients diagnosed with cancer in the final stage of life .
this questionnaire , which did not have any special religious procedure , was originally a special needs questionnaire design for patient with special problems .
the aim was to investigate only spiritual needs and no other topic related to spirituality .
maslow s theory of motivation is the theoretical basis of this questionnaire , but with the assumption that spiritual needs exist at all of maslow s levels , with the move toward deeper levels of fulfillment of more complex and abstract needs . in sni , for each question there was also the survey of reply to the needs along with the survey of needs existence ( according to a yes / no to answer the question : " is this need being met in your life now ? " ) ( 13 ) .
sni was normalized in a group of caregivers of patients with cancer and demonstrated the reliability and validity in the group without illness ( 21 ) .
this tool was created by taylor in 2006 in the usa to investigate the spiritual needs prevalent in patients with cancer and their caregivers based on a qualitative and then quantitative study ( 14 , 22 , 23 ) .
the stem of all the questions in this self - report tool started with " how important is it now to  " , and at the end of each group of questions , an item asked : " how important it is to have my ( or my loved one ) nurse help me satisfy these spiritual interests ? " ( 14 ) .
because need may transmit a negative concept , authors used the word interest to avoid misunderstanding and to decrease patient denial in reporting their needs .
another important difference between this questionnaire and others was the need to review beliefs , which involved a cognitive involvement with concepts such as unfairness of what has been happening , correctness of beliefs about god , 
why did i / we deserve this ?  and finally , receiving a response or gaining acceptance ( 14 ) .
this scale was designed by yong et al . in 2008 in korea with the assumption that spiritual needs vary across cultures . to extract key concepts of spiritual needs ,
both an extensive literature review on spiritual needs and semistructured interviews with 10 hospitalized participants were conducted .
sns had five sub - constructs which were similar to sub - constructs of psnas , but which had one more construct , appreciation of beauty .
on the other hand , the constructs of spirit yielded two other different constructs , positive perspective and reviewing beliefs , which were not included in the constructs of sns .
this questionnaire , which may be the most important assigned questionnaire for the evaluation of spiritual needs of particular patients , was designed in 2010 by bssing et al . in germany .
it was , in fact , a continuation of the dedication of assessing the spiritual needs of special patient populations .
the reason for selecting patients with chronic illnesses such as chronic pain and cancer was that for these patients , one important method of coping with illness was the use of religion and spirituality .
most previous questionnaires focused on the spiritual needs of patients close to death as opposed to those with chronic illnesses .
a novel aspect of spnq was the need of actively giving , which is the need of having an active role in life instead of the role of an afflicted patient ( 16 ) .
spnq has been used in different settings ( 25 ) and also normalized in malaysia , nigeria , poland , france , china , and england and is now normalized in iran . in each country
, the questionnaire has been normalized with minor changes and the priority of needs has been reported differently ( 26 ) .
this questionnaire was developed in 2012 by sharma et al . in the usa and was introduced as a complete tool for spiritual needs assessment in the published paper .
the developers tried to merge all the existing data in literature with experts opinions and also their clinical experiences .
this short questionnaire consisted of 23 questions with scoring ranged between 23 and 89 , such that the closer the score to 89 , the greater the need .
this questionnaire placed needs into three main groups and appeared as an integration of the previous needs questionnaires ( 17 ) .
a noteworthy point is that in the chinese normalization , researchers found that some items that were considered as spiritual needs by western patients were not considered as such for chinese patients ( 27 ) .
this questionnaire was developed by vilalta et al . in 2014 in spain . with the aim of designing a simple , effective and easily tool
, they performed a comprehensive literature review and selected the most common repeated typologies of spiritual needs . after incorporating them , in collaboration with experts who were specialist in theology , ethics , bioethics , psychology and oncology
we did not find any published data about the questionnaire s psychometric evaluation in databases we searched until the time the present article was being written , with the exception of its face validity and a pilot study involving 10 patients ( 18 ) .
this questionnaire was developed by wu et al . in 2015 in taiwan . with the aim of designing a specific tool to assess spiritual needs in acute care hospital patients with different religious beliefs , they merged items obtained from 149 published articles and three patients spiritual needs instruments . after incorporating them
the meaning and hope component referred to the domains of self , nature and environmental aspects of spiritual well - being , and the caring and respect component referred to the domain of communal relationship with others ( 19 ) .

the meaning and hope component referred to the domains of self , nature and environmental aspects of spiritual well - being , and the caring and respect component referred to the domain of communal relationship with others ( 19 ) .
a distinctive feature of this study was collecting the detailed characteristics of the instruments with their strong and weak points .
therefore , those interested in spiritual needs can choose the appropriate instrument regarding the constructs assessed by these instruments . however , the followings are some pitfalls seem to exist in this field of research : a , the similarity of all the aforementioned questionnaires assessed spiritual needs of patients in critical conditions , mostly patients with cancer , and designed questionnaires to answer these specific patients needs . on the other hand , cancer can significantly increase and change patients spiritual needs , because patients rely on spirituality as a strong method to deal with cancer ( 10 , 28 , 29 ) .
further studies are recommended to design appropriate instruments for other patient groups and the healthy population ; b , for assessing spiritual needs , one should understand the voice that lies deep within the respondent that may reveal something of the respondent s inner self .
therefore , despite the advantages of questionnaires in research , clinicians should be cautious of this point and avoid applying instruments stereotypically ( 30 ) ; c , with the exception of the questionnaires mentioned in this paper , there were many qualitative studies to evaluate spiritual needs that considered other variables .
some examples include transcendental needs , mystical needs ( including desire and mystical consciousness ) , which involve abstract aspects of spiritual needs ( 30 ) , and needs such as life beyond the individual , need for continuity and after life , need for truth , and need for freedom and to be free ( 18 ) .
these points highlight the need to study and develop new questionnaires that cover more dimensions of spiritual needs ; d , in most of these questionnaires , normalization information was incomplete . in some ,
the sample volume was not only low , but often used in limited studies , and in most of them , the theoretical bases of the questionnaire design were not mentioned .
therefore , using these questionnaires in clinical daily work should be performed with care until further research is conducted ; e , some concepts of these questionnaires are culture - dependent . for example , in western cultures , listening to music is a spiritual need , while in iran listening to the quran is more significant .
furthermore , depending on the culture in which the questionnaire is used , the priority of needs will change . in the chinese version of snap , for example
, the first priority is the need of actively giving ( not inner peace that is seen in the german normalization ) ( 26 ) . in iran ,
on the other hand , the significant need is going to the prayer hall and participating in mass prayer ( 2 , 30 - 32 ) .
in korea , in contrast with western cultures , some patients are not comfortable in talking about death and unfinished works at the end of life ( 15 ) .
this is important from two perspectives : first , one construct can be measured by different factors in different cultures .
second , because of cultural differences and the relationship between spiritual needs and culture , it can be recommended to design culture - specific questionnaires ; f , historically , a criticism in questionnaire design is the reductionist approach .
it seems that the concept of spirituality varies from religious to secular , and this topic is seen in spiritual needs surveys .
for example , in the aforementioned questionnaires , general concepts such as the need of meaning discovery in illness are weak , and strong concepts such as life beyond the individual were measured by variables such as talking with others .
for example , in top sense , the beauty can achieve ( that is kind of intuitive beauty ) ( 33 ) , while the concept of life beyond the individual was simply about talking with others .
this point should be considered important in culture - specific questionnaire design , especially in eastern cultures where religious concepts have a strong link to spiritual concepts ( 18 , 34 , 35 ) .
first , there were not enough references such as congress papers , abstracts , theses , etc .
the reason was the unavailability of details because of lack of publication in research sites .
second , the concept of spiritual needs is an extensive one for the introduction of which several words can be used and may be overlooked in the keywords .
furthermore , there were many questionnaires that assess different dimensions of spirituality including spiritual needs .
we deleted them from our study because our focus was on the questionnaires that assessed spiritual needs specifically . in conclusion ,
although most of the studies showed that the need of relationship was the center of spiritual needs , the complexity of these needs can not be summarized in this concept ( 25 , 36 ) .
therefore , the assessment of questionnaires should be conducted with a great deal of care and consideration .
this is an aspect that has been ignored in most questionnaires and has led to the lack of harmony in terms of content and assessment .
 contextthe objective of the present review was to collect published spiritual needs questionnaires and to present a clear image of the research condition of this domain.evidence acquisitionfirst , an electronic search was conducted with no limits on time span ( until june 2015 ) or language in the following databases : pubmed , scopus , ovid , proquest and google scholar . 
 all derivations of the keywords religion and spiritual alongside need and its synonyms were included in the search . 
 researches that introduced new tools was then selected and included in the study . due to the limited quantity of questionnaires in this domain and with no consideration given to the existence or lack of exact standardization information , all of the questionnaires were included in the final report.resultseight questionnaires 
 were found : patients spiritual needs assessment scale ( psnas ) , spiritual needs inventory ( sni ) , spiritual interests related to illness tool ( spirit ) , spiritual needs questionnaire ( spnq ) , spiritual needs assessment for patients ( snap ) , spiritual needs scale ( sns ) , spiritual care needs inventory ( scni ) , and spiritual needs questionnaire for palliative care.conclusionsthese questionnaires have been designed from a limited medical perspective and often involve cultural concepts which complicate their cross - cultural applicability .
