Material and Methods: This cross-sectional study was conducted on 156 patients, selected via convenience sampling, with type II diabetes in Shroud (2013). The instruments were a demographic checklist, diabetic quality of life questionnaire and self-efficacy questionnaire. Data analysis was performed by descriptive statistics and Pearson correlation coefficient (0.05). 

Results: in accordance with the results, the quality of life was moderate and the lowest score was related to physical dimension. There was a significant relationship between self-efficacy and all aspects of quality of life in that the patients with higher self-efficacy had the more quality of life. Moreover, there was a significant linear relationship between quality of life and variables such as age, diabetes duration and body mass index. Conclusion: given that the increased self-efficacy is associated with quality of life improvement , it seems likely that we can maximize the quality of life in these patients by applying self-efficacy enhancement programs.

Background: Family caregivers of cancer patients encounter numerous challenges while providing care, and self-efficacy is a key factor in alleviating these negative effects. This study aimed to investigate the psychometric properties of the Persian version of the Caregiver Self-Efficacy Scale (CSES) among caregivers of cancer patients.
Methods: This methodological study employed a cross-sectional design involving 382 family caregivers of cancer patients in a teaching hospital in Iran, in 2024. The CSES was translated into Persian using the forward-backward procedure. The initial translation was assessed for face and content validity through both quantitative and qualitative methods. Construct validity was evaluated using exploratory and confirmatory factor analysis. Discriminant validity was examined using the Heterotrait–Monotrait (HTMT) ratio. Reliability was assessed by evaluating internal consistency using Cronbach's alpha and Mcdonald's omega, and stability was measured using intraclass correlation coefficients (ICCs).
Results: In this study, 53.7% of the participants were male, and the caregivers' mean age was 42.52 ± 11.83 years. Scale-level content validity index was reported 0.97 by expert panel during content validity stage. During the exploratory factor analysis, one item was excluded, leaving seven items were categorized into two factors: caregiver self-management and patient challenges. These factors collectively accounted for 43.9% of the variance in self-efficacy. Confirmatory factor analysis confirmed the adequacy of the model derived from the exploratory factor analysis (RMSEA = 0.05, GFI = 0.947, and CFI = 0.906). The factors demonstrated discriminant validity.  Cronbach's alpha values for the patient challenges and caregiver self-management factors were 0.802 and 0.798, respectively. In addition, the ICC for these two factors was reported to be 0.830 and 0.802, respectively.
Conclusion: The Persian adaptation of the CSES demonstrates satisfactory validity and reliability for assessing the self-efficacy of family caregivers of cancer patients in Iran.
 

Background: Prolonged Grief Disorder (PGD) is a recently recognized mental health condition characterized by persistent and intense grief following the loss of a loved one. While global proportion estimates vary, limited data exist regarding PGD within the Iranian general population. This study aimed to determine the proportion of PGD in Iran and examine associated sociodemographic factors.
Methods: A cross-sectional survey was conducted among 469 general community dwelling in Shahroud, North east of Iran, using convenience sampling technique. Participants were eligible for inclusion if they were over 18 years old, possessed basic literacy skills, and had experienced the loss of a close loved one (such as a spouse, parent, or child) at least 12 months prior to enrollment. Participants completed online forms of the validated Persian version of the Prolonged Grief Disorder Scale (PG-13-R). Sociodemographic data (age, gender, education, marital, and job status) were collected, and multivariate logistic regression was used to identify factors associated with PGD.
Results: The proportion of PGD was 29.6% (95% CI: 28.5–30.5%), with a mean symptom score of 29.54 ± 10.68. A significant difference between PGD-positive and PGD-negative individuals in terms of education (p=0.005) and occupational status (p=0.01). Multivariate analysis indicated that age and education were significant predictors of PGD. Individuals aged 41–60 (OR: 12.7, CI: 1.5 - 107.05, p= 0.019) and over 60 (OR: 14.7, CI: 1.7 - 123.9, p= 0.013) were significantly more likely to meet PGD criteria compared to those under 20. Participants with secondary education were more likely to experience PGD than those with only primary education (OR: 4.1, CI: 2.06 - 8.5, p<0.001).
Conclusion: Prolonged grief disorder affects a substantial portion of the Iranian population, particularly among older adults and those with lower educational attainment. These findings highlight the need for targeted mental health interventions and the development of culturally sensitive diagnostic and therapeutic approaches. Future research should explore the moderating roles of religiosity, loneliness, and social support in grief outcomes to inform comprehensive, culturally grounded care strategies.
 

Background: Palliative care is a holistic approach aimed at enhancing the quality of life for patients with cancer. Given the rising number of cancer patients in Iran, its significance has become increasingly apparent. This study investigates the effect of palliative care on the quality of life and satisfaction of patients with cancer.
Methods: This before-and-after quasi-experimental study was conducted in 2024 on 320 patients with breast, tongue, stomach, thyroid, osteosarcoma, and colon cancer at a teaching hospital in Tehran, Iran. Participants were selected through convenience sampling based on eligibility criteria, including being over 18 years of age, having literacy, being able to speak Persian, and being psychologically stable. The quality of life and life satisfaction of patients were assessed before and after participation in a structured palliative care program. The intervention consisted of six two-hour palliative care sessions, delivered over two months. Data were collected using the Satisfaction with Life Scale (SWLS) and the EORTC QLQ-C30 Quality of Life Questionnaire. Data analysis was conducted using SPSS software, version 26, and a paired t-test was employed for statistical evaluation.
Results: The results indicated that the participants had a mean age of 50.67 years, with a standard deviation of 13.23 years. After receiving palliative care, the overall quality of life score, along with its dimensions (except for emotional functioning, sore throat, and diarrhea), showed a significant improvement (P < 0.001, Cohen’s d = 2.36). Moreover, the intervention led to a significant improvement in patients' life satisfaction, with a p-value of less than 0.001 and a Cohen’s d of 1.01.
Conclusion: The study findings demonstrated that palliative care services, typically provided to individuals nearing the end of life, enhanced the quality of life for cancer patients. Policymakers should prioritize support for patients, and healthcare managers must collaborate to improve and provide palliative care services with qualified personnel, especially nurses.
