The results of the present study show that nurses' demographics,including age, gender, work experience, marital status, andeducation, do not correlate with their perceptions of caringbehaviors and of professional ethics. Also, there was not astatistically significant difference between the participants'perceptions of caring behaviors and professional ethics mean scoresaccording to gender, marital status, and education(Table 2). Thesefindings are consistent with the results of many other studies. Ina study in Iran, except for age, none of the demographic variablesunder study correlate with the medical staff's adherence to code ofethics(27). Inanother study in Iran, the results do not show a correlationbetween nursing students' age and academic semester on the one handand awareness of professional ethics on the other(28). However, according to areview study in Finland, age, gender, and work experience correlatewith nurses' respect for professional ethics(14).
With regard to the existence of a correlation between nurses'demographics and their perception of caring behaviors, a study onIndonesian nurses reports that the correlation between thesubjects' age, gender, education, and clinical experience on theone hand and perception of caring behaviors on the other is notsignificant (29). Similarly, a study in Slovenia shows thatthe care factors in Watson's theory do not have a significantcorrelation with nurses' education(30). Yet, according to a study conducted in anIranian city, marital status is a predictor of caring behaviors(31). Theseinconsistencies in research findings about the existence of arelationship between nurses' demographics on the one hand and theirperceptions of professional ethics or of caring behaviors on theother underline the need for more research in this area.
The results of the present study show that nurses' perceptionsof caring behaviors and professional ethics are relativelysatisfactory. A study on nurses selected from 4 hospitals in anIranian city reports the subjects' caring behaviors mean score tobe very satisfactory(31). According to another study in Iran, fromthe perspective of patients hospitalized in oncology units, nurses'caring behaviors are very satisfactory (32). With regard to professional ethics,a study on 210 inpatients in Iran shows nurses' adherence to codeof ethics for nurses to be satisfactory, which is consistent withthe findings of the present study(33). However, a study in Gambia reportsnurses' respect for ethical values to be inadequate and that nursesdo not comply with code of ethics in that country(15). The majority of nurses ratetheir perception of caring behaviors or their caring behaviors andobservance of professional ethics as satisfactory; however, thesevariables need to be studied from the perspectives of other groups,including patients, colleagues, and other members of healthcareteams, for richer data to be obtained.
According to the results of the present study, there is arelatively significant positive correlation between nurses'perception of caring behaviors and their perception of professionalethics. A review of the available literature did not yield anystudies which address the relationship between nurses' perceptionsof caring behaviors and of professional ethics. Yet, the results ofa study on intensive care unit nurses in Iran shows that, contraryto the findings of the present study, there is not a correlationbetween nurses' ethical sensitivity and caringbehaviors(34).
Based on Watson's theory, caring is a core idea and ethicalideal in nursing which seeks to protect, support, and empowerhumans(35,36). In a reviewstudy, Woods states that the concepts "caring", "nursing", and"ethics of care" have always been inseparable and that nurses'professional practice is recognized by their ethicalcommitment(37).According to Lachman, when an individual decides to become a nurse,he/she is making an ethical commitment to care for patients. Caringcan be regarded as exclusively an ethical act; consequently, caringcan be seen as a duty. Also, caring can be regarded as a commitmentto be present and a passion for becoming involved in patients'needs(38). Manystudies make references to the relationship between caring andethics. In some of them, ethics is introduced as the outcome ofcaring, and in others, caring is introduced as the outcome ofethics. The present study only focuses on the linear relationshipbetween the two. In view of the significance of caring behaviorsand professional ethics in the nursing profession, it is vital thatthese concepts be studied more deeply.
One of the limitations of the study is that the questionnaireswere completed on a self-report basis, which could have createdbias in the results. Therefore, the participants were assured thatall information was confidential and that their responses would nothave any impact on evaluation of their professional performance.They were reminded that the questionnaires had to be completedhonestly and accurately.
