self - esteem is an important state of mind which allows individuals to accept themselves as they are and be self - confident . rosenberg ( 1965 ) considered self - esteem as the positive or negative attitude of an individual toward himself . if an individual has a positive attitude in self - assessment , his self - esteem would be high ; if he has a negative attitude , then his self - esteem would be low . self - esteem is a psychological phenomenon that has a definite effect on the emotional and cognitive dimensions of an individual . the individuals with a high self - esteem tend to perceive themselves worth being respected and approved , important and beneficial . on the other hand , the individuals who have a negative idea about themselves or who have low self - esteem tend to perceive themselves as not very important , lacking lovability , and with no comfort in themselves and their capabilities . high self - esteem is considered important because it is associated with higher levels of psychological health and functioning and low level of self - esteem is undesirable because it is associated with lower levels of psychological health and functioning . one of the major reasons for researchers interest on self - esteem is its effects on health . damaged self - esteem makes it impossible to endure the harsh conditions of everyday life and produces adverse physical and psychological outcomes . therefore , there is always the risk of appearance of mental disease in the postpartum period . the postpartum depression is a disorder of non - psychosis depression according to the study of hendrick et al . as per the american psychiatric association [ diagnostic and statistical manual of mental disorder - iv ( dsm - iv ) ] , brown et al . reported that about 50% of women are affected by depression at the first 3 months after delivery , whereas one - third of them are affected by depression after 3 months of delivery . although several factors influence depression , the psychosocial factors play a strong role in prediction of this disorder . self - esteem is one of the variables that affects deleteriously on the pregnancy outcomes and postpartum period . 's study showed that self - esteem may be a useful predictor of disorders such as anxiety and depression . depression and self - esteem tend to be highly correlated with each other . it has been accepted that depressed people think in a negative manner and report lower self - esteem than non - depressed people . the robustness of the effect also strengthens the potential importance of self - esteem interventions ,  said sowislo . she believes that treatments aimed at reducing depression by way of improving self - esteem could provide not only short - term gains for clients but also long - term protection from depression for those most at risk . it was found that individuals who have effective and positive social problem - solving approach have a high self - esteem . the individuals with high self - esteem generally have more confidence in their initial approaches to the problems and , therefore , they seek less information before offering solutions and making decisions . problem - solving approach is a cognitive behavioral process . by means of problem - solving skills , people can identify and recommend the effective strategies to face stressful situations in everyday life . social problem solving can be viewed as an important conformity mechanism that serves to increase behavioral competence and it leads to decrease in psychological distress . dzurilla suggested that self - esteem may play an important role in the relationship between self - appraised social problem - solving ability and psychological adjustment . also , mccabe et al . found that social problem solving was predicted by self - esteem and depressive symptoms . in aylward 's study , self - esteem emerged as the most important predictor of social problem - solving model . some evidence was found to link the relationship between self - esteem and problem - solving skills . in the study of mahmoudi rad entitled the role of social problem solving and communication skills training on enhancing self - esteem level and its relationship to mental functioning and academic achievement of students ,  it was found that self - esteem scores of the two groups showed significant difference before and after intervention . the researchers stated that the findings suggest a direct effect and positive role of training of communication skills and social problem - solving abilities when a person faces social and personal problems . the study of abuhamzeh entitled  the effect of problem solving training on increasing the self - esteem of students in school  showed that training of problem solving significantly increases overall , academic , social , and family self - esteem in the intervention group than in the control group . this effect remains for up to 2months after the education . in the study of sharifi , it was found that problem - solving training positively affected the self - esteem of students with behavior problems . based on studies , we can conclude that with higher problem - solving skills and social problem solving , we can increase a person 's self - esteem and decrease the depressive symptoms . several studies showed that low self - esteem is associated with increased anxiety and depression . rees conducted an exploratory study of the effectiveness of guided imagery protocol with relaxation on reducing anxiety and depression and increasing self - esteem in primiparas during the first postpartum month . not only relaxation and imagery decrease stress , pain , and anxiety , but also they generate a more positive understanding and a more strong feeling about well - being . with relaxation , the person can attach importance to herself and she can perceive everything that she needs . this develops self - appraised process which is the first important step toward self - esteem . although there is little evidence about the effect of relaxation on self - esteem , its positive effect is somewhat proved . the relaxation training is simple technique and easy to practice at home ; it can increase the self - esteem and decrease psychological problems . relaxation and problem - solving training are behavioural  cognitive interventions that help to decrease depressive symptoms and increase self - esteem ; also , the self - esteem of depressed women is low during postpartum period . hence , a study should be performed for determining the more effective and simpler technique . this study was done with the aim of comparing the effects of problem - solving skills training and relaxation on the self - esteem of women in postpartum period . this was a clinical trial with a control group in 39 weeks in postpartum period and was conducted after getting permission from the ethics committee of mashhad university of medical science . all women on days 1520 after delivery who referred to mashhad health centers from december 2009 to june 2010 participated in the study after completing the consent form . the inclusion criteria were : literate women , 1835 years old , with the term neonate , singleton , healthy infant , the history of lack of chronic medical illness , without history of previous depression , and no smoking . at first , edinburgh postnatal depression scale ( epds ) was completed by the subjects . women whose get score 10 or above , completed beck depression inventory ( bdi ) . those who obtained a score of 1428 and confirmed to be depressed by a clinical interview conducted by a psychologist ( based on dsm - iv criteria ) in the health centers were divided into three groups randomly : problem - solving training ( n = 26 ) , relaxation ( n = 26 ) , and control group ( n = 28 ) [ figure 1 ] . eysenck self - esteem scale which has seven items and a score of 140 was completed by the women at the onset of research . interventions in the two groups of problem solving and relaxation were performed by a researcher ( midwife ) . the researcher had been taught by a clinical psychologist and after gaining the skills , she received a certificate of performance of relaxation and problem solving skills . a pilot study had been done on depressed women in ebne - sina hospital in mashhad before conducting the main study . chart of sampling process intervention was performed in the problem - solving group , which consisted of six sessions weekly in the healthy centers . the researcher notified the appointment by telephone to the research units before the intervention . in the problem - solving group , at the first session which lasted 1 h , the participants were trained in five skills of problem solving ( general orientation , problem definition and formulation , generation of alternatives , decision making , and verification ) . in the next sessions which lasted 4550 min , depressive symptoms of women were studied according to the beck inventory ; different solutions were presented by women and the best solution was selected for performing until the next session . the recording checklist of problem - solving sessions was completed by the researcher in each session . in the relaxation group , the first two sessions of relaxation were performed in the health center , and each session lasted about half an hour ; the other sessions took 1020 min . in the first session of relaxation training , the causes of postpartum depression and the ways of controlling it were discussed and the relaxation purposes were explained . also , women were trained about how to contract and relax their 16 groups of muscles similar to jacobson 's method , and the practice was demonstrated by the researcher . then the practice was repeated once in the presence of a researcher by a training mother . in the second session , progressive muscle relaxation technique was performed once again by a mother in the presence of the researcher and after correction and ensuring the accuracy of the technique , the cd of progressive muscle relaxation was given to the women to perform the exercise daily at home . in the next four sessions , in addition to the exercises of relaxation performed at home , the imagery techniques ( forest visualization , beach , pilgrimage sits , and green space with good climate ) were performed by the researcher . the relaxation exercise was performed by the women at home for about 20 min daily . the form of recording the exercises performed at home was given to women and it was emphasized to bring it along with them in each session . at the beginning of each session , the positive and negative experiences of women were considered and they asked about how they could perform relaxation techniques . the control group recoursed to health center weekly and they bring the recording checklistof postpartum depressive symptoms with themselves and routine care after delivery is performed for them according to the booklet of safe mother . nine weeks after delivery , each of the three groups completed the eysenck self - esteem scale again as a post - test . in this research , the instruments of data collection included the edinburgh depression scale , beck depression inventory - ii , eysenck self - esteem scale , the socio - demographic questionnaire , recorded checklist of depressive symptoms , and recorded checklist of problem - solving sessions . the edinburgh scale is a standard instrument for screening depressive women in the postpartum period . this instrument assesses the feeling of women in the past 7 days and it has 10 items and each item has a score of 03 . it assesses the feeling of women in the past 1 week and its answers are scored between 0 and 3 . eysenck self - esteem scale has 7 items and each item has a score of 020 . the first two sections included 20 questions about personal characteristics , pregnancy , and recent childbirth , which were completed before implementing interventions and its two questions were completed on referring to patients files . the third section included four questions that collected information on the availability of someone to help at home , sleeplessness difficulties , and breastfeeding , and it was completed 9 weeks after delivery . the validity of beck depression test was confirmed by mohammad khani in tehran , and in this study , the alpha coefficient was 0.827 . the data obtained in this study were analyzed using descriptive statistics , analysis of one - way variance , chi - square test , and spearman correlation coefficient by spss software . intervention was performed in the problem - solving group , which consisted of six sessions weekly in the healthy centers . the researcher notified the appointment by telephone to the research units before the intervention . in the problem - solving group , at the first session which lasted 1 h , the participants were trained in five skills of problem solving ( general orientation , problem definition and formulation , generation of alternatives , decision making , and verification ) . in the next sessions which lasted 4550 min , depressive symptoms of women were studied according to the beck inventory ; different solutions were presented by women and the best solution was selected for performing until the next session . the recording checklist of problem - solving sessions was completed by the researcher in each session . in the relaxation group , the first two sessions of relaxation were performed in the health center , and each session lasted about half an hour ; the other sessions took 1020 min . in the first session of relaxation training , the causes of postpartum depression and the ways of controlling it were discussed and the relaxation purposes were explained . also , women were trained about how to contract and relax their 16 groups of muscles similar to jacobson 's method , and the practice was demonstrated by the researcher . then the practice was repeated once in the presence of a researcher by a training mother . in the second session , progressive muscle relaxation technique was performed once again by a mother in the presence of the researcher and after correction and ensuring the accuracy of the technique , the cd of progressive muscle relaxation was given to the women to perform the exercise daily at home . in the next four sessions , in addition to the exercises of relaxation performed at home , the imagery techniques ( forest visualization , beach , pilgrimage sits , and green space with good climate ) were performed by the researcher . the relaxation exercise was performed by the women at home for about 20 min daily . the form of recording the exercises performed at home was given to women and it was emphasized to bring it along with them in each session . at the beginning of each session , the positive and negative experiences of women were considered and they asked about how they could perform relaxation techniques . the control group recoursed to health center weekly and they bring the recording checklistof postpartum depressive symptoms with themselves and routine care after delivery is performed for them according to the booklet of safe mother . nine weeks after delivery , each of the three groups completed the eysenck self - esteem scale again as a post - test . in this research , the instruments of data collection included the edinburgh depression scale , beck depression inventory - ii , eysenck self - esteem scale , the socio - demographic questionnaire , recorded checklist of depressive symptoms , and recorded checklist of problem - solving sessions . the edinburgh scale is a standard instrument for screening depressive women in the postpartum period . this instrument assesses the feeling of women in the past 7 days and it has 10 items and each item has a score of 03 . it assesses the feeling of women in the past 1 week and its answers are scored between 0 and 3 . eysenck self - esteem scale has 7 items and each item has a score of 020 . the first two sections included 20 questions about personal characteristics , pregnancy , and recent childbirth , which were completed before implementing interventions and its two questions were completed on referring to patients files . the third section included four questions that collected information on the availability of someone to help at home , sleeplessness difficulties , and breastfeeding , and it was completed 9 weeks after delivery . the validity of beck depression test was confirmed by mohammad khani in tehran , and in this study , the alpha coefficient was 0.827 . the data obtained in this study were analyzed using descriptive statistics , analysis of one - way variance , chi - square test , and spearman correlation coefficient by spss software . each of the three groups showed no significant statistical differences regarding their age ( p = 0.680 ) , husband support ( p = 1.000 ) , satisfaction in marital life ( question by likert scale ) ( p = 0.506 ) , unwanted pregnancy ( p = 0.392 ) , neonate sex ( p = 0.253 ) , social support ( cassidy social support scale ) ( p = 0.078 ) , self - esteem ( p = 0.145 ) , and the score of edinburgh depression scale ( p = 0.258 ) [ table 1 ] . in this study , 53.8% women had high , 42.5% had moderate , and 3.8% had low self - esteem . descriptive characteristics of problem - solving training , relaxation , and control groups before intervention the mean of self - esteem score was 103.7  21.6 before intervention in the problem - solving group that increased to 117.9  9.7 after the intervention . also , in the relaxation group , the mean of self - esteem score was 112.1  16.7 before the intervention , which increased to 117.0  11.8 after the intervention . in the control group , the mean of self - esteem score was 111.8  13.1 in the beginning of the study and it changed to 113.5  10.4 at the end of the study . by means of self - esteem scale , the self - esteem levels in each group were obtained . in our study , the self - esteem of relaxation group was moderate ( 42.3% ) and high ( 57.7% ) before the intervention and reached a moderate level in 23.1% and a high level in 76.9% of the cases after the intervention . results showed relaxation can increase moderate self - esteem to high self - esteem . in the present study , the self - esteem score was low in 11.5% , moderate in 34.6% , and high in 53.8% of the problem - solving group before the intervention , which became moderate in 15.4% and high in 84.6% of the cases after the intervention . in the ninth week after delivery at which the intervention of relaxation and problem - solving training groups was completed , the statistical results of one - way variance analysis showed that the three groups had no significant differences at the end of study ( p = 0.288 ) . but according to the mean difference of self - esteem score before and after the intervention ( by one - way anova test ) , it was found that there was significant difference among the three groups [ table 2 ] . the tukey test showed that the two groups of relaxation and problem solving had significant difference ( p = 0.018 ) . also , the intervention groups had significant difference compared to the control group ( p = 0.000 ) [ table 3 ] . comparison of mean difference of self - esteem scores in three groups before and after intervention comparison of three groups based on tukey test generally , the three groups showed a significant difference regarding the mean difference of self - esteem score . in this study , both the interventions of relaxation and problem solving could increase the self - esteem score , while the control group showed no increase in self - esteem score . these findings indicate that both types of training ( problem solving and relaxation ) can produce a positive change in the overall self - esteem and improve the behavioral problems of women later in the postpartum period . findings and the methods used in the study of ress are similar to those of our study . unfortunately , no other study has been found that examined the effect of relaxation on self - esteem . aylward et al . found that self - esteem is the most important predictor of social problem - solving model and high self - esteem plays a major role in the relationship between problem - solving ability and psychological balance . the study of abuhamzeh showed that training of problem solving significantly increases the overall self - esteem in the intervention group than in the control group . although abuhamzeh worked on healthy students , the method of performing problem - solving skills is similar to our study . also , sharifi showed that problem - solving training could increase the self - esteem in students with behavioral problems . the present study showed similar results , but sharifi performed problem solving in 9 weeks , each session lasting 90 min , and we performed six sessions of 4560 min duration each . in addition , although the type of instrument used to evaluate self - esteem and the sex ( male and female ) and number of individuals were different in this study compared to our study , the results of both studies showed the effectiveness of this type of training in increasing the self - esteem score . we observed that the training of problem - solving skills increases the self - esteem score of depressed women more than relaxation training in the postpartum period . although problem solving had more effect on self - esteem , the relaxation method is simple and easily practiced at home . relaxation is accepted by most people and no need to haunt or many facilities . while in problem - solving method , an average of 214 min per patient visit with a psychiatrist or a general practitioner is required , and thus is time consuming . however , no study is found that compared the effect of relaxation and problem solving on self - esteem . although relaxation technique is simpler than the procedure of problem solving , the constitution of the classes and meetings for women can increase the self - esteem of subjects because women reach better understanding of the problem and solve it , while the relaxation technique was performed at home in a shorter time ( 20 min vs. 45 min sessions ) . in addition to the above studies , the study of stephens in southern connecticut state university shows problem - solving training can boost the self - esteem of the participants . in this study , self - esteem scores were measured by a scale rating 21 questions before and 3 months after intervention . the average of self - esteem score increased after the intervention ( from 1.76 before intervention to 3.53 after intervention ) . the results of study showed that this type of training can increase the self - esteem scores in men , as well as in special occasions such as domestic violence and mental health problems such as postpartum depression . overall , the findings of the present study confirm that relaxation training and problem solving are successful as they can have an effect on a person 's self - concept and increase his / her self - esteem . also , women with postpartum depression often use dysfunctional problem - solving styles in stressful situations . the styles and techniques of treatment that are representative of the style of problem solving including cognitive behavioral therapy are fit and advantageous for the treatment of psychiatric and behavioral problems and can help women suffering from postpartum depression . because of the importance of self - esteem during pregnancy and postpartum period , it is recommended that these two types of training programs are performed in pregnancy and the postpartum period with longer follow - up period . since the midwife as a primary carer in the postpartum period could play a role in the prevention and promotion of self - esteem in women with depression , it is recommended to consider and apply both types of training programs in health centers by trained midwives . one of the study limitations was the time limit for performing this research in the pregnancy period . also , this study was not practical as a double - blind method ; the researcher herself was responsible for training the women . in addition , the relaxation technique was performed at home on a daily basis and so careful control by the researcher was not possible . so , we attempted to ensure that these techniques were performed on a daily basis only with repeated phone calls and by encouraging women , as well as by providing educational cds . also , it was not possible to use from clinical interview by psychiatrist due to high costs during two stages ( before and after the intervention ) ; therefore , such as similar studies , only depression was measured using a standard questionnaire . the strengths of this study is performance in three groups randomly and at various health centers . due to the lack of bias in the results consideration of postpartum depression using two questionnaires in the first step and confirmation by the clinical psychologist in the next phase of the study is another strong point . based on the results of this study and the relationship of self - esteem with depression and the major role of problem - solving skills in improving the self - esteem score , we suggest that this simple technique is performed in the health centers by midwives for increasing the self - esteem and decreasing the depressive symptoms , and thus improving the mental health . also , relaxation was effective in increasing self - esteem . therefore , relaxation is proposed as an auxiliary or replacement method along with other methods in increasing the self - esteem .
background : self - esteem is a determinant factor of mental health . 
 individuals with low self - esteem have depression , and low self - esteem is one of main symptoms of depression . 
 aim of this study is to compare the effects of problem - solving skills and relaxation on the score of self - esteem in women with postpartum depression.materials and methods : this clinical trial was performed on 80 women . 
 sampling was done in mashhad healthy centers from december 2009 to june 2010 . 
 women were randomly divided and assigned to problem - solving skills ( n = 26 ) , relaxation ( n = 26 ) , and control groups ( n = 28 ) . 
 interventions were implemented for 6 weeks and the subjects again completed eysenck self - esteem scale 9 weeks after delivery . 
 data analysis was done by descriptive statistics , kruskal 
 wallis test , and analysis of variance ( anova ) test by spss software.results:the findings showed that the mean of self - esteem scale scores was 117.9  9.7 after intervention in the problem - solving group , 117.0  11.8 in the relaxation group , and 113.5  10.4 in the control group and there was significant difference between the groups of relaxation and problem solving , and also between intervention groups and control group.conclusions:according to the results , problem - solving skills and relaxation can be used to prevent and recover from postpartum depression .
