Abstract
This study examined the effectiveness of a structured group therapy of Park and Seligman (Version 2) (2007) on the rate of post-traumatic growth of positive psychological variables in women with breast cancer who completed their courses of chemotherapy and radiotherapy. Totally, 11 cancer patients were examined in this study. Using a questionnaire, PTG, post-traumatic growth of positive psychological factors were measured before therapy sessions. Then, an 8-session structured group therapy was held for 8 weeks; at the end, PTGI was recompleted by members of the group. For data analysis, t-test was used to compare dependent and independent samples. Results indicate that positive treatment structured approach of Park and Seligman has a positive effect on increased participants’ positive components (new possibilities, personal strength, appreciation of life and relationships with others), while it does not influence Spiritual changes. Two variables (Surgery and education) as moderating variables are effective on effectiveness of the treatment.

Introduction
Life-threatening diseases such as cancer are best known by DSM-IV as a stressor which can precipitate post-traumatic stress disorder. The main measures to inhibit cancer include preventive measures; so as research has proved, at least 40% of cancers can be prevented. Appropriate diagnostic measures is explained in the form of early diagnosis and appropriate treatment; so that, at least 40% of cancers can be completely cured. Supportive care of cancer patients is the last part of measures to cure cancer in psychological science 1.
Trauma is an emotionally painful, disturbing and sudden experience often led to lasting physical and mental effects. Cancer can cause trauma which challenges people. Coping with these challenges may lead to positive growth in their mental components; this is called ‘PTG’. PTG is a component of positive changes characterized by a traumatic experience and a painful event, back to a higher level of functioning before the onset of trauma. PTG includes positive changes such as a greater understanding of life, shifting priorities in life, more heat in intimate relationships with others, greater sense of personal ability, recognizing new opportunities or ways of life and development of spiritual growth 2. Diagnosis and treatment of breast cancer is an experience with stress and anxiety. Women in whom the disease is diagnosed early experience drug therapy and surgery with potential negative side effects, such as hair loss, nausea, lymph edema, and sexual problems. Long-term treatment doubts the ability of women in establishing social role as housewives or employed and possible future return to work. High levels of stress have a long-term negative effect on women’s self-esteem which has a very bad influence on family functioning, marital life, and low quality of life. About 10-30% of diagnosed patients experience clinical symptoms of post-traumatic Stress Disorder (PTSD). Given the devastating consequences of the disease and its effects on individuals and families, it is required to find psychological ways for these people to cope with the illness, psychological well-being and survival time considering the nature of the disease shifting from a fatal to chronic disease 3.
Research has shown that adequate protection of the patient plays an important role in maintaining mental integrity, consistency and coping with the cancer; in addition, it has positive effects on quality of life. By strengthening and increasing awareness, support causes people to experience less stress. Totally, it Increases coping with illness, quality of life and survival time 4-5. Among the types of breast cancer, the most common type is in women. Cancer causes changes, stresses and different effects on the lives of cancer patients and their family. Cancer-related crises imbalance of body cause imbalanced body and soul. Another possible reaction is TG depression which is seen frequently in women with breast cancer 6.
The main goal of positive psychology is to understand mental health; this psychological dimension is classified into three subtypes including positive emotions, positive individual traits, and positive institutions and organizations 7.
Positive group therapy that is focused primarily by positive psychotherapy roots from Carl Rogers’ theory. Seligman believes that, ‘combining theoretic ideas of Carl Rogers and positive psychological research, we can provide an environment where people move to a happier and healthier life by minimizing stresses and facilitating abilities’. The scores of Tedeschi and Calhoun PTG inventory (21-item Form) are indicator of PTG 7. Another example of positive group therapy designed by Park and Seligman Consists of 8 1:30h sessions, held for 8 weeks for adults with mild to moderate symptoms of depression. The group includes 10-12 clients and a group facilitator. Every session, Participants receive a worksheet containing a detailed description of practices of that week and a space for recording different aspects of their experience during exercise [3]. A complex interaction of factors related to Starting and maintaining PTSD includes post-traumatic, pre-traumatic and underlying variables 8. Personality variables, including neuroticism, introversion are generally associated with severe symptoms of PTSD. The growing empirical literature revealed that many survivors of trauma experience positive psychological changes after a traumatic event, Even as a direct result of trauma or as a kind of learning that happens through great efforts to cope with trauma 9.
Positive psychological changes include increased appreciation of life, creating new life priorities, increased sense of personal competence, a sense of deeper meaning, identifying new possibilities, improving intimate relationships and positive spiritual changes 10. Erik Fromm has stated that the pain and challenge that person tolerates when setting his basic concerns (freedom, isolation, death and the meaning of life), and the role they play in his life can lead to a better understanding of self, self-conscious and positive growth 11. Many cancer survivors experience the positive changes when experiencing illness 12. PTG dimensions include improved interpersonal relationships, appreciating life, spirituality, personal strength and positive changes in life priorities 13. The attraction of positive changes reported in breast cancer patients after diagnosis and treatment has expanded in recent years 14-16. Some researchers found that 53% of women with breast cancer reported positive changes in their lives since diagnosis 17. Sears and colleagues (2003) found that 83% of women with breast cancer reported positive interests in their experience 18.
Using Positive group therapy of Park and Seligman 3, the present study examined PTG in patients with cancers. Purpose of this study was to evaluate the positive effect of group therapy of Park and Seligman on growth of positive psychological components on women with breast cancer. Moreover, the effect of moderating variables such as income, education, occupation, previous medical history, surgical history, education of spouses has been discussed.
Experiments
Methods
In this study, a pre-test and post-test quasi-experimental design was used. The scheme consists of a group of subjects measured twice.
Participants
Participants included all literate cancer patients in Zahedan, Iran. The patients completed cycles of chemotherapy and radiotherapy and were willing to participate in this positive psychological group therapy. Therefore, only 11 breast cancer patients were selected; maximum people which can participate in group therapy were also 12. Participants range in age from 26 to 72 years old (on average, 48.72).
Variables
Independent variable was 8-session positive group therapy of Park and Seligman with discussion about the practice of previous sessions in which people were supposed to participate actively. This corresponding therapy has been received by the researcher from the authors. Dependent variable was change in positive psychological factors (PTG) which was measured after and after the positive psychological group therapy. Control variables were gender and type of cancer. Therefore, all members of the sample were female with breast cancer.
Materials
Seligman personal strengths survey is used to measure strengths of adults including strengths (short form). The amount of strengths of a subject is based on age, geographic location, education, and occupation. There is the original 240-item form in Seligman web site on Persian. This survey is based on 5-point Likert scale completed in 25 minutes, but without time limit.
Munsch scale was used to measure. Short-term items 10 represent the casing (positive and negative), and the long-term items 14 represent the fitting dimensions (positive and negative). Each of Positive and negative casing aspects has 5 items and each of positive and negative fitting aspects has 7 items. In Overall, the scale includes 24 items. The items are scored in a three-point scale (yes = 2), (No = 0), (I do not know = 1). Positive and negative casing aspects with 5 items will be scored from 0 to 10 and positive and negative fitting aspects with 7 items will be scored from 0 to 14. The total score of the scale is calculated by a formula with respect to the positive and negative casing and fitting aspects.
Reliability
Reliability of this test is reported as 0.70 by retest after 18 months. The internal consistency of the test was 0.71.
Data Collection
To gather information, first all literate people with breast cancer were collected; then, people who completed their chemotherapy and radiotherapy were separated. Totally, 11 patients were willing to participate in courses of positive psychology group therapy and attended in the sessions. In each session, worksheets of last week were collected from and worksheets of the next week were given to participants. Every week after exercise, the participants in group therapy had to complete Munsch Happiness scale and obtain the scores to measure the effect of exercise of that week. At the end of the sessions, participants were asked to complete PTGI. Positive psychology group therapy lasted for 2 months. The present study attempted to examine the effect of group therapy of Park and Seligman on increased PTG components in people with breast cancer. A pre-test and post-test quasi-experiment was used by convenient sample. T-test was used to compare scores of subjects in post-test and pre-test. To compare means, independent t-test was used.
Results
The mean age of the subjects was 48.72 ranging from 26 to 72. Distribution of subjects in terms of employment shows that the samples included 54.5% employed and 45.5% housewives. Distribution of subjects in terms of previous disease shows that the samples included 63.6% without previous illness, and 36.4% with previous illness. Distribution of subjects in terms of surgery shows that the samples included 18.2% without history of surgery and 81.2% with a history of surgery. Distribution of subjects in terms of revenue shows that the samples included 63.6% with one million or less and 36.4% with above one million Tomans revenue. Distribution of subjects in terms of education shows that the samples included 36.4% with diploma or higher. Results showed that spouses of patients were 63.6% with diploma and lower, 36.4% with diploma and higher. Some descriptive indices related to scores of the subjects were calculated before and after positive group therapy; the results are presented in table 1.

As Table 1 illustrates, there is a difference between pre-test and post-test scores of all components. To determine whether there is a significant difference between pre-test and post-test scores of all components, t-test was used to compare mean correlated samples. Results are presented in Table 2. According to Table 2, there was a significant difference in mean scores of the four components (new possibilities, personal strengths, appreciation of life, relationships with others) before and after therapy using a 95% confidence; only, there was no significant difference in the fifth component (spiritual growth).
In order to investigate whether revenue, education, occupation, previous medical history, surgery, education of spouse, have an effect on the effectiveness of the used methods, the mean difference between PTG variable before and after implementation (pilot) was calculated and results were analyzed for mean differences in different components.
To examine whether revenue causes differences in the effectiveness of positive group therapy of Parks and Seligman on PTG, t-test was used to compare mean independent samples. The results are summarized in Table 3 and 4. As Table 3 shows, highest and lowest difference in observed pre-test and post-test means was related to appreciation of life and spiritual growth, respectively. As Table 4 shows, there is no significant difference between mean scores of pre-test and post-test in groups with revenues less and more than one million in a confidence level of 95% for the five components of PTG. That means revenue played no role on effectiveness of Park and Seligman’s group therapy. To explain, the difference between mean scores before and after the implementation of Positive group therapy was significant at 90%.

There is no significant difference between mean scores of pre-test and post-test in groups with education lower and higher than diploma in a confidence level of 95% for four components of PTG (new possibilities, personal strengths, relationships with others, spiritual growth). The difference was only significant for mean scores of appreciation of life before and after the positive group therapy. This indicates that education has been effective as a moderating variable on effectiveness of the Park and Seligman’s positive group therapy.
To examine whether occupation causes differences in the effectiveness of positive group therapy of Parks and Seligman on PTG, t-test was used to compare mean independent samples. The results are summarized in Table 7 and 8.

There is no significant difference between mean scores of pre-test and post-test in groups with and without previous surgery in a confidence level of 95% for four components of PTG (new possibilities, personal strengths, relationships with others, spiritual growth). The difference was only significant for mean scores of appreciation of life before and after the positive group therapy. This indicates that previous surgery has been effective as a moderating variable on effectiveness of the Park and Seligman’s positive group therapy.
To examine whether education of spouses causes differences in the effectiveness of positive group therapy of Parks and Seligman on PTG, t-test was used to compare mean independent samples. The results are summarized in Table 13 and 14. As Table 13 shows, highest and lowest difference in observed pre-test and post-test means was related to appreciation of life and spiritual growth, respectively. There is no significant difference between mean scores of pre-test and post-test in groups with spouses who had educations higher or lower than diploma in a confidence level of 95% for the five components of PTG. That means, education of spouses played no role on effectiveness of Park and Seligman’s group therapy. It is noteworthy that difference was only significant for appreciation of life in a confidence level of 90% before and after positive group therapy.

Discussion And Conclusion
In the conducted Park and Seligman’s positive group therapy intervention, participants were administered a series of positive psychology exercises in which participants were taught how to increase new possibilities, personal strength, appreciation of life, relationships with others using exercises of using competences, expressing positive things, gratefulness, enjoying every day experiences, responding proactively, summarizing life and practicing positive things to help people. Generally, learning these skills can increase PTG in these people to experience positive emotions (joy of life), engagement (interactive life), meaningfulness (meaning of life) along with disease, associated with variables such as occupation, previous medical history, previous surgery, revenue, education and spouse’s education.
To examine whether positive group therapy has an effect on PTG of subjects with breast cancer, the results of comparing PTG before and after group therapy showed that the intervention has been effective on 4 PTG components (new possibilities, personal strengths, appreciation of life and relationships with others) (Table 2, p≤0.05) while no significant difference was found for the fifth component (Table 2, p≤0.05). A significant difference in pre-test and post-test of new possibilities can be due to the fact that a purpose of the treatment is to change life style using strengths existing in physical and psychological structure of people. The therapist focused on this fact through exercises. The significant difference was under these exercises and solutions. Personal strengths are another trait with significant difference in this study. It is noteworthy that strengths were identified in the first session. In all sessions, it was a task to consider this trait and report using strengths. The difference was due to the focus on this trait through treatment. Appreciation of life was the third significant component. The therapist attempted to introduce values of life and beauties of appreciation of life to people with cancer (participants). Throughout the sessions, participants discussed and exercised appreciation of life. As the results show, the exercises were successful (such as exercise on enjoying daily life). Regarding the component, relationships with others, proactive/constructor exercises and appreciation letter of others were tasks of the sample group through which relationships were improved and corrected. The results can show effectiveness of this part. Concerning spiritual growth, Tedeschi and Calhoun showed that a person faced with a traumatic event might lead to a deeper understanding of the existential awareness and a deeper need for spiritual connection in helping to create a sense of meaning in life. It seems that this component only grows when confronting with trauma and other variables are ineffective on development of this component.
All the above are part of a treatment program for creating PTG in patients and significant difference confirms the success of this method in promoting its growth.
The present study examined the effect of positive group therapy of Park and Seligman on increased PTG components. Results indicate that the used psychological intervention is able to accelerate the occurrence of PTG. Looking at the various researches done in the field of creating PTG, It is noteworthy that, the growth takes place only in a group of persons; Second, the time after the occurrence of a traumatic event is effective 19. However, the present study has shown that occurrence of PTG can be accelerated by an objective planning which plays an important role in disease adjustment. Planning also facilitates damages resulting from crisis. In addition, it can provide the opportunity to create PTG in all damaged groups. Using t-test to compare mean independent samples in a confidence level of 95%, education and previous surgery as moderating variables influenced effectiveness of the positive group therapy. In 90%, revenue and spouse’s education as moderating variables influenced effectiveness of the positive group therapy. Findings of the present study are consistent with Linley and Joseph 20.
Accordingly, education and previous surgery were effective on effectiveness of the therapy. In other words, findings suggest that education can be considered as an effective factor on treatment. People with higher education get more interests of the Park and Seligman’s positive group therapy, which was predictable. People who were exposed to stress and experienced less PTG were prone to receive more interests of the therapy.
