Several theories exist about the impact of social capital on Qol which have been documented in many studies -often through cross-correlation methods. But the big problem of these studies is lack of direction of causality. For this reason, in this study we sought to design an intervention to enhance social capital and investigate its effect on Qol.
This arrangement as pre-test and post-test intervention study with a non-intervention group of 29 women with breast cancer. The results of this study indicated that interventions caused social capital enhancement in a successful first step in the intervention group which in turn leads to enhanced Qol, compliance and reduced pain.
Nevertheless, in non-intervention group these variables declined and this shows regardless of measures to help these patients, their Qol will deteriorate and so they did not follow their treatment as ordered.
Two groups were matched in terms of demographic variables at pre-test and this means that differences in demographic variables cannot explain the differences in average social capital between two groups. Among demographic variables, only socio-economic status has a significant relationship with social capital and other variables did not relate to it.
Nategh Pour found that age, education, marital status, employment and income to the elements of knowledge, attention to public affairs, formal, and informal participation are directly related to the social capital (
34). Mohammadi pointed out that gender, native status and place of birth, income, and education are correlated with social capital (
35). Andishmand realized the positive impact of education and residence area on social capital (
36).
Sharbatian asserted that variables such as gender, marital status, place of residence and place of birth are not associated with the enjoyment of social capital. However, social class, family relationships, personal resources, educational status, and social interactions on campus and in the community are the most important predictors of social capital (
37). These findings have not been established in our study.
Evaluation of Qol showed that In H/F , S/E ,P/S and family was 48/4 % , 51/6 % , 44/8 % , 69 % of subjects had moderate levels , respectively. 48/3 % of these patients followed up their treatment at a moderate level and 27/6 % at an acceptable level. 69 % of patients reported their pain as severe and 20/7 % as moderate and 10/3 % as low level. In other words, the majority of patients have medium or poor Qol and very few people have a high level of Qol.
Several studies had highlighted the negative effects of cancer on Qol (
27,
38,
39). Nematollahy concluded that the majority of patients (%66) had a moderate level of Qol (
40), that is consistent with the result of the present study, but Moshtagh reported Qol in these patients as low (
41). Nurthous showed a relatively high Qol for African-American women. They were generally optimistic, had effective family function, and symptom of stress generally were low in them (
42).
Ferrell pointed out the majority of women had moderate mental and psychological status and this was clue to medical issue (
43). However, Sammarco reported good Qol (
26).
These differences may be due to differences in the cultural background, age of subjects, data collection instruments, and patients’ heterogeneity in terms of cancer level and type of treatment.
Based on the findings of this study, age was not significantly associated with any of the dimensions of Qol. Marriage and the number of child had a negative correlation with health and functional dimension that can be explained with decrease in energy, hopelessness, worry about future, lack of opportunities for expectant future, and awful disadvantages which can lead to decreased Qol.
Education and employment had positive and meaningful correlation with Qol generally with H/F and S/E scales. This may be due to mind engagement and deviance from disease to other issues, finance independency, social relationships, more information and better access to supportive and informative sources.
These findings have been supported in several studies such as Safaei (
23), Lehto in Finland (
20) and Pandey in India (
22). Socio / economic status had meaningful relationship with family scale, probably due to high levels of livelihood and ability to continue treatment.
Northouse in Michigan, in his study on Qol in African American women with breast cancer, did not observe any meaningful relationship between demographic variables with Qol (
42). Furthermore, in the Schultz and Winstead Analytical-discretional study there was not any relationship between age and education with Qol and its scales (
21).
Treatment compliance generally had positive correlation with Qol and its scales. High level of treatment compliance may be accompanied with higher level of Qol. This finding has been confirmed by Malekpour (
44). Pain obviously had a negative correlation with Qol.
According to the results, change in social capital, Qol, compliance and pain in breast cancer patients during intervention and after that indicated positive effects of the intervention on these variables.
Social capital, Qol, and treatment compliance in the intervention group increased and in the non-intervention group decreased or remained stable. Pain decreased in both groups but this was significantly higher in intervention group.
Differences between two groups in posttest were meaningful, and this emphasizes on intervention usefulness. Correlation between social capital with Qol and compliance was positive and with pain was negative.
4.1. Limitation
An intrinsic limitation of this study was as follows: parts of the results obtained were due to chemotherapy and should not be attributed entirely to this intervention (both groups received chemotherapy and this research was done in that period). Perhaps, if chemotherapy treatment was not successful, the present results could have changed and would not relieve in pain so much lack of patient’s cooperation.
This study was conducted in patients with cancer and may not have that effect on other patients or can be more effective in healthy individuals. Because cancer is a chronic disease and these results achieved should not be attributed to the other people.
Over the period of intervention, an expectance effect has been declined and we have come to the conclusion that 12 sessions were boring for patients. The recommended number of sessions is limited to 6 - 8 sessions.
However, this study represents the first clinical study on how to enhance social capital and the form of a protocol has been prepared. Also the impact of social capital on pain and compliance is tested for the first time that had noticeable finding and this protocol has been registered in IRCT.
Therefore, it is suggested that the study will be done in a spring or summer when patients do not have restrictions and it is better to study in larger sample.
until more definite conclusions can be obtainedabout the impact of social capital on pain relief and perform this intervention in other chronic, painful, deadly and threatening the self-concept of the individual disease.
4.2. Conclusion
Based on results of this study, patients need social and emotional support more than anything to survive diagnosis and treatment process with less stress. It seems that participation in cooperative groups , team works , spending more time with friends and family members through increasing in social capital cause spiritual improvement, compatibility with circumstance, stress refraction, enjoying social support and thus acquired more information about this disease that can help to improve Qol and treatment compliance.
So it is suggested to use methods that enhance social capital for improving Qol and survival in patients through increasing knowledge , emotional and information support about adherence benefits and increasing in spirit and happiness for continuing the treatment.
