  Abstract 

BACKGROUND: The psychological well-being of midwives is very important in the context of providing health services to two vulnerable groups of society, namely, mothers and infants. Therefore, the present study was conducted aiming to investigate the effect of positive psychological interventions on the psychological well-being of midwives.
MATERIALS AND METHODS: The present study was a randomized clinical trial with pretest-posttest design along with a control group. The statistical population of the study included all midwives working in community health centers of Mashhad City, Iran, which were first selected through cluster sampling method from five health centers of the city, i.e. centers 1 and 3. Then, all centers and subsidiary bases of these centers were listed, and the centers and bases were divided into two groups of intervention and control by simple random allocation method. Sixty respondents were randomly assigned to two equal intervention and control groups and responded to the Ryff's Psychological Well-being questionnaire in two stages of pretest and posttest. Educational interventions based on interventions, including Seligman's PERMA model, in which psychological well-being is defined in terms of five domains namely positive emotions (P), engagement (E), relationships (R), meaning (M), and accomplishment (A), were conducted in eight sessions of 2 h (two sessions per week). Data were analyzed using independent t-test, paired t-test, Mann–Whitney test, and Wilcoxon test.
RESULTS: There was a significant difference between the posttest scores of the two intervention and control groups in the total psychological well-being variable (P < 0.001).
CONCLUSION: Given the findings of the study, it is suggested to use the Seligman's PERMA model to improve the psychological well-being of midwives in health centers.

  Introduction Top


Occupational burnout is a well-known psychological reaction with a high prevalence in the midwifery profession,[1] which is created in response to chronic psychological stress and involves three elements of fatigue or emotional analysis, depersonalization, and lack of personal success.[2] In addition, this problem is one of the most important factors decreasing the productivity of midwifes in the workplace and depleting their ability to effectively carry out their duties and responsibilities.[3] Midwives provide care services in areas where threatening or stressful events may occur. They may consider their work as harmful. This has important implications for the well-being of midwives.[4] Several studies have indicated the high prevalence of occupational burnout among midwives.[5],[6],[7],[8] Therefore, organizational strategies are required to prepare midwives for such duties, support them to deal with this occupational injury, and provide effective interventions for those with significant symptoms.[4] Fortunately, despite the undeniable role of occupation in the formation and incidence of occupational burnout, the way of responding of the individual to these conditions is important in the final examination of occupational burnout, and this means that individual factors have a significant effect on whether the person suffers from the occupational burnout. In other words, regardless of the conditions, demands, and pressures of work, it depends on the characteristics and abilities of individuals to effectively act against these pressures. Individual factors associated with job burnout have led the burnout in organizations to be considered as a structural phenomenon, and mainly as an unavoidable result of some occupations. However, paying attention to personal factors in burnout and finding probable individual features and circumstances decreasing the underlying causes of suffering of this harm by people protect organizations against the harms, in addition to supporting individuals against the damages in the underlying conditions of burnout. Recently, the relatively new idea of positive psychology has led to new variables to be addressed in this field, which, by better understanding and enhancing the positive resources provided to the individual, can contribute to understanding the process of occupational burnout and providing solutions for exposure and prevention.[9] In recent years, various interventions have been developed in the field of positive psychology with the aim to create positive results of emotions, behaviors, and positive cognition.[10] These interventions are, in fact, a series of voluntary activities that target emotions, cognition, and behavior with the aim of improving well-being.[11] Studies on positivist psychological interventions have been conducted on the well-being of individuals to such extent that several meta-analysis and review investigations have been conducted in this field. For example, Sin and Lyubomirsky showed that positive psychological interventions have been effective in increasing the well-being and reducing the symptoms of depression.[12] Similarly, in a meta-analysis in 2013, Bolier et al. showed that positive psychological interventions have been effective in improving the well-being of individuals.[13] In addition, in the organizational context, Meyers et al. in a systematic review have shown that there is a relationship between positive organizational interventions and well-being and employees' performance.[14] In a newer examination, Chakhssi et al. also investigated positive psychological interventions. This study also showed that positive psychological interventions can help reduce the stress and physical and mental problems of individuals while increasing their well-being.[15] The PERMA model is one of the positive psychological interventions, recently developed by Seligman (2011) in order to help enhance well-being among individuals. This model consists of five components including positive emotions (P), attraction (E), positive relationships (R), meaning (M), and achievement (A).[16] Various evidence suggest that this model of well-being is associated with increasing satisfaction with life, creativity, moral development, and civic behaviors.[17] Other studies also show that there is a relationship between well-being and a higher level of job success, better friendly relationships, productivity, customer satisfaction, quality of medical care,[18] and services [19] as well as improved physical health through affecting the body's immune system and protection against stress.[17] Job burnout is the second most frequent occupational injury and the inevitable result of midwifery profession; In addition, this profession is considered a significant occupation in the area of community health care to ensure health for the mother and the newborn. Thus, promoting the well-being of people working in this profession has a great impact on maintaining this workforce and on the quantity and quality of their services. Therefore, the present study was conducted with the aim to investigate the effect of positive psychological interventions on the psychological well-being of midwives.


  Materials and Methods Top


The present study was a randomized clinical trial with pretest-posttest design with control group that lasted from September 23, 2015 to March 20, 2016. The statistical population of the study included all midwives working in community health centers of Mashhad City, Iran, which were first selected through cluster sampling method from five health centers of the city, i.e. centers 1 and 3. Then, all centers and subsidiary bases of these centers were listed, and the centers and subsidiary bases were divided into two groups of intervention and control by simple random allocation method. All individuals eligible to enter the study in each center were placed in the same group. In this way, information dissemination between the two groups was prevented. The sample size was obtained using the formula for comparing the means, and based on the results of the pilot study with 95% confidence and 80% power, a total of 17 respondents were obtained in each group, and taking into account the probability of drop of samples, sampling continued until the completion of each group as thirty respondents (a total of sixty respondents). During the study, 13 midwives were excluded from the study in the intervention group due to irregular participation in the sessions. There was no drop of midwives in the control group [Figure 1]. The most important criteria for selection of the respondents were at least a midwifery associate degree and at least 1 year of work experience in community health centers, marriage, nonpregnancy, lack of referring to a psychiatrist during the past 6 months, or admission to a hospital due to mental illness, a history of the use of mentally affecting drugs, the lack of a medical condition leading to a disability in performing occupational duties, and not receiving a severity score from the Anxiety, Stress, and Depression Scale (DASS 21). In addition, the most important exclusion criteria were the absence of more than one session in the training course, the occurrence of major stressful incidents during the study, and failure to do homework for three consecutive sessions.

The data collection tool consisted of:

Demographic information form of respondents (including three parts of the individual characteristics, occupational characteristics, and midwives' lifestyle).

  • Ryff's Psychological Well-Being questionnaire (84 items): This scale was created by Carrol Ryff in 1980. The questionnaire was designed in a 6-point Likert scale (completely agree to completely disagree) to measures six dimensions of autonomy, environmental mastery, personal growth, positive relationships with others, purposefulness in life, and self-acceptance. The minimum and maximum scores of the respondents in the psychological well-being scale were 84 and 504, respectively. Moreover, the total of these six factors were calculated as the total score of psychological well-being. Due to the positive correlation of this scale with the Positive Psychotherapeutic Checklist, developed by Rashid and Seligman (2013) to measure the full life (well-being) of individuals using five subscales of positive emotions, engagement, meaning, relationships, and achievement, it can be claimed that this scale is an appropriate tool for examining well-being,[20] with the validity and reliability determined in various studies.[21] In this study, its content validity with an overall reliability of alpha = 0.90 in the environmental mastery (0.68), self-acceptance (0.82), positive relationship with others (0.91), autonomy (0.72), purposeful life (0.76), and personal growth (0.88) was confirmed.


Demographic information form and Ryff's Psychological Well-Being questionnaire were provided to the respondents to be completed by them. Then, two of the researchers with a PhD degree in clinical psychology (teacher of positive psychology workshops) and a master midwifery student who had received the certificate of the Positive Psychology Workshop conducted eight sessions of 2 h (two sessions per week) for the intervention group [Table 1]. The intervention group was divided into two groups of 15, and sessions were held at the Sib Consultation Center. After completing the intervention, the Ryff's Psychological Well-Being questionnaire was completed by midwives in the two intervention and control groups. At the end of the study, the presentation slides of the sessions along with the training package were provided to the control group.

This study was approved by the code IR.MUMS.REC.1394.447 at the Ethics Council of Mashhad University of Medical Sciences and registered with the IRCT2016010225813N1 code at the Iranian Registry of Clinical Trials. All ethical codes established by Mashhad University of Medical Sciences were observed.


  Results Top


According to the results, the mean ± standard deviation (SD) of age of the midwives in the intervention and control groups was 36.89 ± 9.73 and 31.76 ± 5.12 years, respectively, which were significantly different based on the independent t-test (P = 0.010). Mean ± SD of work experience in the two groups was, respectively, 165.96 ± 86.86 and 66.97 ± 43.79, which had a significant difference based on the results of the Mann–Whitney test (P < 0.001).

Midwives were not homogeneous in the two groups in terms of age (P = 0.010), employment status (P < 0.001), and work experience (P < 0.001). However, they were homogeneous regarding variables of depression (P = 0.053), stress (P = 0.160), anxiety (P = 0.620), and other variables [Table 2].

Moreover, at the beginning of the study, midwives in the intervention and control groups were compatible in terms of variables of lifestyle such as daily exercising (P = 0.750), having enough sleep daily (P = 0.21), daily resting (P = 0.13), religious activity, (P = 0.07) and life satisfaction (P = 0.58).

According to the results, the analysis of covariance of none of the variables that were heterogeneous at the beginning of the study was not significant on the psychological well-being of midwives (P > 0.050), and only the effect of intervention was significant [Table 3].

Comparison of the mean of total score and psychological aspects of well-being between the two groups before and after interventions is presented in [Table 4]. The mean score of total psychological well-being among midwives before intervention was not significantly different between intervention and control groups based on the Mann–Whitney test (P = 0.520), but the difference was statistically significant after intervention (P < 0.001) [Table 4].

Comparison of the mean score of the dimensions of “positive relationship with others, purposeful life, and individual growth” before and after interventions in the control group did not have a significant difference; however, the mean score of “self-acceptance, autonomy, and environmental mastery” in the control group showed a significant decrease after interventions [Table 4].

Furthermore, based on the paired t-test, the mean total score difference between the psychological well-being of midwives in the intervention group before and after intervention was statistically significant (P = 0.002) [Table 5].

  Discussion Top


Findings of this study showed that positive psychological interventions can be effective in the psychological well-being of midwives. However, the comparison of the mean changes in the scores of each well-being dimension before and after the intervention in the control group showed decrease at the end of the study so that this decrease was significant in three dimensions of “self-acceptance,” “environmental mastery,” and “autonomy.” The probable cause of this decline is that the level of well-being reported by the individuals is itself influenced by the extent of good feeling they have when answering questions. The emotional (moral) state of people when responding is very important in how to report the well-being. The findings of the present study were in line with the findings of the studies conducted by Sin and Lyubomirsky,[12] Bolier et al., Meyers et al.,[14] Ranjbar Noushari et al.,[22] Hasanvandi et al.,[23] Khodayarifard et al.,[24] and Abadi et al.[25] on the effectiveness of positivist psychological interventions in promoting the well-being of individuals. The positivism and interventions through which the well-being of individuals are influenced can be easily explained through the theory of the creation and spread of Friedrichsen and the five related hypotheses. In this theory, it is stated that positive emotions lead to the expansion of the treasury of thought and action of individuals. Gradually, many personal resources are created in the individual (physical, social, mental, and psychological resources) that can be used by him/her in difficult conditions. Besides, another hypothesis of this theory is neutralization through which the existence of positive emotions causes neutralization of negative emotions. The next hypothesis is associated with the belief that those who experience more positive emotions can better cope with the difficult and unfavorable conditions of life and are more resilient. The last hypothesis of this theory is also the hypothesis of flourishing, which, in fact, includes the ratio of experience of positive emotions to negative ones. If a person experiences three positive emotions for any negative emotion, he/she flourishes.[26],[27] In this way, it seems that positivism, through increasing the treasury of thought and behavior, can lead to well-being. Furthermore, positivist-oriented psychological interventions can also affect well-being through creating meaningfulness and the ability to use personal capabilities and talents. In terms of the method of work, which is an experimental and controlled study, the present study is capable of examining the effects of positive psychological interventions on the psychological well-being of midwives instead of merely addressing the correlational relations. Moreover, one of the weaknesses of the study was the lack of follow-up of the effectiveness of positive psychological interventions on the happiness and well-being of midwives. The researchers encountered some restrictions in this study, including the need for timely and regular presence of the respondents in the sessions, and remaining in the group until the final result was obtained, and 13 respondents were merely excluded for this reason. The individual differences of the midwives in the motivation, the level of learning, and the proper conduct of homework of the sessions affected the study results and could not be controlled by the researchers, therefore, they attempted to partially control them by random allocation.


  Conclusion Top


According to the study findings, positive psychological interventions were effective in increasing the psychological well-being of midwives. In practical terms, the present study suggests holding a course of positive psychology workshops to relevant authorities to improve the well-being of employees and reduce occupational burnout because individuals with a high standard of well-being can demonstrate flexibility in the face of difficult challenges and demands of the workplace as well as the emotional and psychological needs of the job and adapt to the conditions.
