Objective: Proper psychological interventions for enhancing public health and mental welfare in nurses are of great importance. This study intended to explore the influence of the teaching psychological welfare on marital satisfaction and self-efficacy in nurses of Imam Khomeini hospital.
Methodology: The method of the present study was semi-experimental with a pre-test post-test design and a control group. Hence, 24 nurses were selected from Imam Khomeini hospital, by using convenience sampling, and they were divided into two groups: experiment and monitoring. By using a 47-questions marital satisfaction questionnaire and a 17-questions general self-efficacy questionnaire, both groups were pre-tested. Then the test group, received lessons on psychological welfare within ten sessions, but the control group received no interventions. Afterwards, both groups were post-tested, and the data collected were analyzed by using descriptive and inferential statistics methods through SPSS software.
Findings: Findings showed that teaching psychological welfare significantly increased marital satisfaction and self-efficacy in nurses (p < 0.001).
Conclusion: From this research, it was concluded that teaching psychological welfare is an effective strategy for those with risky jobs like nurses, because it is highly efficient, especially when it is performed in groups, because it is cheap, and because it is acceptable by different working people.
Human forces are the most valuable assets in every organization; the higher the quality of these assets, the more productive and resistant the organizations will be . One of the most robust systems in every society is hospitals, because they are directly connected to the individuals’ health. Nurses form the biggest part of the hospital staff. Therefore, recruiting and maintaining them is vital . Nurses are individuals who are responsible for controlling and monitoring hospitals 24 hours a day; hence, they are continually exposed to numerous stressors . Many examinations showed that 93 percent of the nurses are regularly affected by stressors in work environments, which can also affect their physical and mental health . Therefore, paying attention to the factors that improve the nurses’ mental status is of great importance.
It is an undeniable fact that for every individual, work life and family life are two crucial fields. In spite of the fact that they are seemingly two separate areas in the humans’ life, the cause and effect dynamisms of families and work have been emphasized by scientists since years ago . Every person’s satisfaction with either field significantly affects different aspects of life. Regarding family factors, marital satisfaction is one of the most important factors, which lead to a healthy family performance; playing a crucial role in the endurance of marriage lives. Also, it can have a big impact on other aspects of life such as jobs . Marital satisfaction is an index of healthy marital relationships, including the individuals’ emotional, cognitive, and intellectual perceptions of their marriage life. Andreassen CS, Hetland J, Stale Pallesen S (2013)  believe that marital satisfaction is the adjustability of the status quo and the expected status. Based on this definition, marital satisfaction happens when the status quo matches what couples expect in their marital relationships. Also, in literature related to marital satisfaction, the presented definition was ignored by Ellis. Andreassen CS, Hetland J, Stale Pallesen S (2013)  define marital satisfaction as something which includes feelings of joy and being pleased with all relationships. In other words, marital satisfaction is the couples’ general assessment of marital relationships. This general assessment could be a reflection of the individuals’ happiness with the marital life or a combination of their satisfaction with the aspects related to marital relationships . Therefore, by emphasizing different positive aspects, marital satisfaction could significantly affect the individuals’ lives; hence, it requires attention and examinations.
In addition to the marital satisfaction, another variable which is imperative in the individuals’ professional and even personal lives, and which should be examined more carefully, is the feeling of being self-efficient, especially in nurses. Self-efficacy is an assuredness that an individual has successfully performed a particular behavior and waits for the expected results. In fact, it is a person’s belief in achieving a particular goal . As a factor which significantly influences resources to achieve goals (Vancouver, More and Yoder, 2008), self-efficacy is one of the valuable items that receives a lot of attention from positive psychology . It was conceptualized as a belief in the organization and doing necessary activities for achieving a set goal. In addition, using a social-cognitive approach to jobs, self-efficacy helps form positions and motivations directly and indirectly (by affecting the expected results) . High self-efficacy regulates the level of stress; high self-esteem increases welfare and physical health, and it helps recover quickly from chronicle diseases . Also, a low self-efficacy leads to anxiety, depression, and low intellectual welfare . Therefore, the examining factors that enhance self-efficacy are crucial for clinical researchers.
One of the most important psychological interventions for the improvement of psychological conditions and mental health is teaching psychological welfare. Psychological welfare is defined as the development of the individuals’ real talents, including six components: purpose in life, positive relations with the others, personal growth, self-acceptance, autonomy, and environmental mastery . In various investigations, it was noted that with a change in psychological welfare, it is possible to predict the individuals’ perceived eligibility and health . Hence, the present study was conducted to examine the effect of teaching psychological welfare on marital satisfaction and self-efficacy in nurses of Tehran’s Imam Khomeini Hospital.
The current research was semi-experimental with a pre-test post-test design and a control group. The statistical community of the study consisted of all the nurses working in Tehran’s Imam Khomeini Hospital (autumn, 2016), who were selected by using the convenience sampling method. To calculate the sample size, 12 people were chosen for each group, considering the fact that the minimum sample size for the experiment samples was 12 . To increase the statistical competence and manage probable drops in the number of participants, the sample size was 24 (n = 24) for each group. Participants were selected from all the nurses working in Tehran’s Imam Khomeini Hospital, by using a voluntary non-random sampling method. Criteria for entering the present study included conscious tendency to participate, ability to take part in sessions and doing assignments, cooperating to complete the tools, having an age range of 25 to 45, having a minimum education (diploma), having a psychological balance, and having a physical balance. The criteria for exiting the study were the following: not having a tendency to participate, being absent for more than three sessions, not having the ability to take part in sessions and do assignments, and having a history of training or psychological therapy, which was not part of the present study.
The method of performing the research included the selection of some nurses working in Tehran’s Imam Khomeini Hospital, by using a voluntary non-random sampling method; and when they had the entrance criteria, they were randomly divided into two groups: experiment and control. Before conducting the study, the ethical principles were observed. First, participants were given precise explanations on the purpose of the research and the effect of such studies on the psychological conditions; then they were asked whether they wanted to participate in the study or not. Afterwards, the researcher collected all the information connected to the participants, and they were assured that these data were confidential and kept by the researcher. Next, the experiment group received group lessons on psychological welfare within ten sessions, but the control group received no interventions. Finally, both groups were post-tested. The protocol of psychological welfare training sessions is presented in Table 1.
The tools used in the present study included a demography questionnaire, Sherer’s et al. general self-efficacy questionnaire, and Enrich’s marital satisfaction questionnaire.
Demography questionnaire: The demographic questionnaire included items such as age, gender, education, field of study, and marital status. This survey was provided and evaluated by the researchers of this study.
Enrich’s short-form marital satisfaction questionnaire: This questionnaire was designed by Olson et al.  to evaluate the potential problematic contexts and identify the settings for power and marital relationships. This test had two forms, one with 115 questions, and the other with 125 questions, which were composed of 12 sub-tests. Because the primary form had multiple questions, it tired respondents. In addition, they were provided a short form of this questionnaire that had 47 questions. Using Cronbach’s alpha coefficient, the reliability of the primary form of Enrich’s marital satisfaction survey was calculated to be 0.92. Using Cronbach’s alpha coefficient, Soleimanian calculated the reliability of the short-form questionnaire to be 0.90 . In the present study, the short form of the questionnaire was used . Amiri Majd M, Zari Moghadam F (2011)  did an extensive research on the validity of the test. By using the retest, they calculated the reliability of the trial to be between 0.65 and 0.94 and reported its difference to be 0.90. Examinations were conducted with the help of this scale, for happy, consistent, and divorced couples and those who wanted to get divorced approved the validity of this magnitude.
General self-efficacy questionnaire (G.S.E.S): this scale made by Sherer et al. (1982) included 17 items. The Self-efficacy Questionnaire measures the individuals’ capability of coping with different situations. This questionnaire was set based on a five-point Likert scale; “I completely disagree” responses received a score of 1, and “I completely agree” responses received a score of 5; high scores showed a high self-efficacy in people. When marking this questionnaire, questions 3, 8, 9, 13, and 15 were in line with “agreement”, and the rest of the questions were marked in a reverse format. The reliability and validity of the questionnaire: To analyze the data, “SPSS-20” software was used. To analyze the research data in a descriptive statistical level, the statistical method used indexes such as average, standard deviation, rate, and frequency percentage; and in an inferential statistical level, it used the tests of a single-variable multivariate covariance analysis model.
The demographic characteristics of the sample in the present study are presented in Table 2.
As shown in Table 1, the most frequency of the respondents in the present study was related to individuals between the ages of 31 and 35, with 12 members (30 percent). Moreover, the least frequency of the respondents was related to people between the ages of 25 and 30, with eight members (20 percent). Also, the average of those “surveyed'” years was 34/ 15, and the standard deviation was 7/ 36. The other data related to the demographic features of the present study are presented in Table 2.
As shown in Table 3, in the experiment group, the mean of the marital satisfaction and self-efficacy increased in the post-test stage, compared to the control group.
As shown in Table 4, the hypothesis of zero about the equality of both groups’ variances in marital satisfaction and self-esteem was approved. It means that for marital satisfaction and self-efficacy, the variances of both groups were equal in the society, with no significant differences. Therefore, following Loin’s pre-hypothesis, it was possible to perform a covariance analysis of the results to examine the hypothesis of the study.
As presented in Table 5, a significance level of all tests (p > 0.001) showed that at least in one of the dependent variables (marital satisfaction and self-efficacy), there was a significant difference between the two groups. Moreover, based on the eta square, 0.59 percent of the differences between the individuals were related to the effect of independent variable, i.e. intervention method (teaching psychological welfare). On the other hand, because the statistical competence was 0.95, which was higher than 0.80, the sample size for performing the research was acceptable. The results were connected to the significant difference of each dependent variable presented below.
Based on the data presented in Table 6, since the significance level was p > 0.001, the difference between the marital satisfaction and the self-efficacy between both groups was approved. Also, it was stated that 0.18 percent of the changes in the score of marital satisfaction and 0.55 percent of the variations in the score of self-efficacy were due to the independent variable (teaching psychological welfare). Therefore, it could be said that teaching psychological welfare increases marital satisfaction and self-efficacy in nurses.
Regarding the fact that the current study was aimed at examining the effect of teaching psychological welfare on the marital satisfaction and self-efficacy in nurses of Imam Khomeini Hospital, findings obtained from single-variable and multivariate covariance analysis showed that teaching psychological welfare significantly increased the marital satisfaction and self-efficacy in nurses of Imam Khomeini Hospital. It was in congruence with the other findings obtained from studies conducted by Parvin N, Fatemi A, Aminian F, Rafiee L (2015), Pourghaffari S, Pasha GHR, Attari YA (2010), Shakarami M, Davarnia R, Zahrakar K, Gohari S (2015) [17-19].
To express their similar findings, Parvin N, Fatemi A, Aminian F, Rafiee L (2015)  stated that the psychological lessons on marriage enabled individuals to exchange their messages explicitly. Also, couples without such skills could continue their marriage life. On the other hand, not using life competencies in a correct way might lead to disorders in life as well as collapses in relationships. To express their similar findings, Pourghaffari S, Pasha GHR, Attari YA (2010)  stated that those nurses who manage to implement strategies in their lifestyles after they finish training sessions will be able to make differences in their marriage lives. If they have complaints about their relationships with their husbands and if they feel that they cannot adaptively act in situations, they will not feel that their needs and intentions are fulfilled. Thus, they will not be pleased with their marriage lives. However, changes in life patterns and producing interest in participants of psychological welfare training sessions led to a new attitude to marital relationships followed by positive emotions and hopefulness. Individuals who manage to make a difference in their lifestyles, after finishing training sessions, come to a new philosophy of life and will be able to enjoy their lives.
The finding that teaching psychological welfare increases self-efficacy in nurses is in congruence with the findings obtained from studies conducted by Fallahian R, Aghaie A, Atashpoor A, Kazemi A (2014), Asghari F, Saadat Atefi Korjundani S, Janalizadeh Kokneh S (2015), Peymani N, Ezzati Rastegar Kh (2013), Jannati Jahromi M, Moein L, Yazdani L (2011), Soltani Majd AH, Taghizadeh ME, and Zareh (2015) [14,20-23]. To express their similar findings, Fallahian R, Aghaie A, Atashpoor A, Kazemi A (2014)  stated that teaching psychological welfare has numerous advantages, the most important of which are an improvement in inter-personal relationships, self-acceptance, dominance over the environment and so on, which lead to an increase in the self-esteem and self-efficacy of individuals. Also, improvements in the mental states of people after participating in the training sessions can be referred to, which are important factors helping in the improvement of self-efficacy. Self-efficacy is the product of the past conditions and failures. If by training, individuals are offered solutions to coming to terms with the failures leading to success, it could be hoped that they will resort to challenging assignments and handling them. Therefore, teaching psychological welfare increases self-efficacy.
