    Front Psychol, 2021;12:671124.
    PMID: 34658994 DOI: 10.3389/fpsyg.2021.671124
    Background: The coronavirus pandemic can cause unprecedented global anxiety, and, in contrast, resilience can help the mental health of people in stressful situations. This study aimed to assess anxiety, hyperarousal stress, the resilience of the Iranian population, and their related factors during the coronavirus disease 2019 (COVID-19) epidemic. Methods: A cross-sectional study was conducted in 31 provinces in Iran between March 18 and 25, 2020. A four-part questionnaire, including the demographic information, the State-Trait Anxiety Inventory (STAI-y1-a 20-item standard questionnaire for obvious anxiety), the Connor-Davidson Resilience Scale (CD-RISC-a 25 item standard questionnaire), and the stress hyperarousal subscale from the Impact of Event Scale-Revised (IES-R), was used to collect data. The ordinal multivariable generalized estimating equation (GEE) model was used to identify correlates of the psychological factors mentioned above. The Fisher exact test was used to investigate the relationship between anxiety, stress, resilience, and the COVID-19 outbreak. All analyses were conducted with SPSS 26 and GIS 10.71. Results: The findings show that most people had moderate-to-severe anxiety (80.17%) and a high level of resilience (96.4%) during the COVID-19 epidemic. The majority of participants had a moderate level of stress (58.9%). The lowest and highest prevalences of psychiatric disorders were in Sistan and Baluchestan (3.14 cases per 100,000 people) and Semnan (75.9 cases per 100,000 people) provinces, respectively. Men and unmarried people were the only variables significantly associated with anxiety and resilience. Age, gender, and education were significantly associated with hyperarousal stress. Conclusion: The high and moderate levels of anxiety and stress in Iranians can have negative effects on the well-being and performance of the people and can lead to serious problems. Also, high resilience during negative life events (such as the COVID-19 pandemic) is associated with the well-being in the lives of people. The results of this study can be used in interventions and other psychological studies.

    Front Psychiatry, 2021;12:754831.
    PMID: 34777060 DOI: 10.3389/fpsyt.2021.754831
    This study investigates the relationship between spiritual well-being, social support, and financial distress with depressive symptoms due to the COVID-19 pandemic. A path analysis was used to analyze data collected from 1,156 Iranian participants via an online survey. The results showed that spiritual well-being and social support were negatively related to depressive symptoms and financial distress. The impact of COVID-19 events showed negative associations with depressive symptoms. In addition, the link between spiritual well-being and financial distress with depressive symptoms was partially mediated by the impact of events.

    J Relig Health, 2019 Aug;58(4):1060-1071.
    PMID: 29511922 DOI: 10.1007/s10943-018-0587-1
    The purpose of this study was to investigate the relationship between spirituality with quality of life and stress of Malay Muslim breast cancer patients in Malaysia. In addition, the moderating role of education on this relationship was examined. Participants consisted of 145 conveniently selected Malay breast cancer patients. The results indicated that the more spiritual respondents reported a higher level of quality of life and lower level of stress. Moreover, education weakened the relationship between spirituality with quality of life and stress.

    Pahlevan Sharif S, Sharif Nia H, Lehto RH, Moradbeigi M, Naghavi N, Goudarzian AH, et al.
    J Relig Health, 2021 Apr;60(2):999-1014.
    PMID: 31646425 DOI: 10.1007/s10943-019-00931-6
    The purpose of the present study was to examine the relationship among spiritual intelligence, spiritual well-being and death anxiety among Iranian veterans. In this predictive correlational study, 211 veterans completed King and DeCicco's Spiritual Intelligence Scale, Paloutzian and Ellison's Spiritual Well-being Scale and Templer's Death Anxiety Scale-Extended. After confirming the reliability of the constructs using intra-class correlation coefficient, partial least squares structural equation modeling method was utilized to assess the impact of spiritual well-being and spiritual intelligence on death anxiety. This study found a significant positive relationship between spiritual intelligence and death anxiety after controlling for the effects of age, education level and disability. However, there was a significant negative relationship between spiritual well-being and death anxiety among Iranian veterans. Negative relationships were found between spiritual well-being and death anxiety among Iranian veterans. However, spiritual intelligence had a positive impact on death anxiety.

    Sharif Nia H, Chan YH, Froelicher ES, Pahlevan Sharif S, Yaghoobzadeh A, Jafari A, et al.
    Health Promot Perspect, 2019;9(2):123-130.
    PMID: 31249799 DOI: 10.15171/hpp.2019.17
    Background: Meteorological parameters and seasonal changes can play an important role in the occurrence of acute coronary syndrome (ACS). However, there is almost no evidence on a national level to suggest the associations between these variables and ACS in Iran. We aim to identify the meteorological parameters and seasonal changes in relationship to ACS. Methods: This retrospective cross-sectional study was conducted between 03/19/2015 to 03/18/2016 and used documents and records of patients with ACS in Mazandaran ProvinceHeart Center, Iran. The following definitive diagnostic criteria for ACS were used: (1) existence of cardiac enzymes (CK or CK-MB) above the normal range; (2) Greater than 1 mm ST-segment elevation or depression; (3) abnormal Q waves; and (4) manifestation of troponin enzyme in the blood. Data were collected daily, such as temperature (Celsius) changes, wind speed and its direction, rainfall, daily evaporation rate; number of sunny days, and relative humidity were provided by the Meteorological Organization of Iran. Results: A sample of 2,054 patients with ACS were recruited. The results indicated the highest ACS events from March to May. Generally, wind speed (18 PM) [IRR = 1.051 (95% CI: 1.019 to1.083), P=0.001], daily evaporation [IRR = 1.039 (95% CI: 1.003 to 1.077), P=0.032], daily maximum (P<0.001) and minimum (P=0.003) relative humidity was positively correlated withACS events. Also, negatively correlated variables were daily relative humidity (18 PM) [IRR =0.985 (95% CI: 0.978 to 0.992), P<0.001], and daily minimum temperature [IRR = 0.942 (95%CI: 0.927 to 0.958), P<0.001]. Conclusion: Climate changes were found to be significantly associated with ACS; especially from cold weather to hot weather in March, April and May. Further research is needed to fully understand the specific conditions and cold exposures.
  6. Fear of negative appearance evaluation and attitude towards mammography: Moderating role of internal health locus of control,cancer worry and age
    Pahlevan Sharif S, Ahadzadeh AS, Ong FS, Naghavi N
    Health Promot Perspect, 2020;10(3):220-229.
    PMID: 32802758 DOI: 10.34172/hpp.2020.35
    Background: Mammography screening tends to reduce mortality rate through early detection. One of the barriers to mammography screening is fear of negative appearance evaluation(FNAE). This study investigated the impact of internal health locus of control, breast cancer worries and age on the relationship between FNAE and attitude towards mammography. Methods: A cross-sectional, questionnaire-based survey design was used. Samples were Iranian women, living in Iran, aged at least 30 years old, without any history of cancer, and had not performed mammography previously based on self-report. In total, 823 samples were collected through conducting an online survey from April to June 2016. The questionnaire consisted of several instruments including attitude toward breast cancer screening procedures scale, FNAEscale, the internal dimension of the multidimensional health locus of control, and two items to measure breast cancer worry. Using covariance-based structural equation modeling the model was tested. Results: The interaction of FNAE with internal health locus of control (β = -0.128, P<0.05,CI: -0.200, -0.056), breast cancer worry (β = 0.090, P<0.05, CI: -0.162, -0.017), and age (β =-0.095, P<0.05, CI = -0.163, -0.026) was significant. The three tested moderators dampened the positive relationship between FNAE and negative attitude towards mammography. Conclusion: More information about the screening procedure should be given to women to overcome their fear. The findings indicate the need for interventions seeking to shift women's health locus of control from external to internal. Women with low level of cancer worry need more attention.

    J Med Internet Res, 2015;17(2):e45.
    PMID: 25700481 DOI: 10.2196/jmir.3564
    Today, people use the Internet to satisfy health-related information and communication needs. In Malaysia, Internet use for health management has become increasingly significant due to the increase in the incidence of chronic diseases, in particular among urban women and their desire to stay healthy. Past studies adopted the Technology Acceptance Model (TAM) and Health Belief Model (HBM) independently to explain Internet use for health-related purposes. Although both the TAM and HBM have their own merits, independently they lack the ability to explain the cognition and the related mechanism in which individuals use the Internet for health purposes.

    Int J Health Care Qual Assur, 2018 Jun 11;31(5):391-399.
    PMID: 29865960 DOI: 10.1108/IJHCQA-02-2017-0026
    Purpose The purpose of this paper is to evaluate the Persian version of the Attitude toward Breast Cancer Screening Procedures Scale (ABCSPS) among Iranian women. Design/methodology/approach In this methodological study, 1,000 Iranian women completed a demographic questionnaire and the 14-item Persian ABCSPS. The scale's construct validity was evaluated using exploratory and confirmatory factor analysis. Internal consistency and reliability were assessed using Cronbach's α and McDonald's coefficient ω. Findings The exploratory factor analysis revealed a two-factor solution accounting for 55.1 percent of the variance. The two-factor measurement model had a good fit with all factor loadings greater than 0.5, which were statistically significant. The results showed good reliability and internally consistency ( α=0.767 and 0.872; ω =0.979 and 0.997). Moreover, model structure was invariant across different income groups. Originality/value The Persian ABCSPS translation demonstrated good validity and reliability among Iranian women. The results also showed that the scale had a multidimensional structure. Regarding proper psychometric properties, the validated scale can be used in future studies as a reliable and relevant breast cancer screening attitude measure.

    PMID: 33797864 DOI: 10.1002/nop2.854
    AIM: The purpose of the present study was to evaluate the reliability, validity and factor structure of the Persian version of the BMPN in Iranian university students.

    DESIGN: Cross-sectional.

    METHODS: Study was conducted among Iranian medical sciences students from April to May 2020. A total of 660 students participated in the online self-administrated questionnaire. Construct validity, convergent and divergent validity, and reliability of P-BMPN were evaluated.

    RESULTS: The Exploratory factor analysis showed that the Persian version of the BMPN has 17 items with four factors: dissatisfaction, autonomy Satisfaction, relatedness satisfaction and competence satisfaction that explained 40.17% of the total variance. Based on confirmatory factor analysis, all goodness-of-fit indices confirmed the model fit.

    CONCLUSION: These results suggest that the Persian version of the BMPN is a reliable and valid measure to assess satisfaction and dissatisfaction of the psychological needs in Iranian university students.

    Int J Nurs Pract, 2017 Apr;23(2).
    PMID: 28058748 DOI: 10.1111/ijn.12513
    Nonpharmacological methods of pain relief such as acupressure are becoming increasingly popular worldwide. Practitioners often claim that such methods are highly effective and less invasive than analgesic drugs, but available empirical evidence is largely inconclusive. This study aimed to test the hypothesis that, postacupressure intervention, the amount of pain experienced by sampled leukemia patients, who received acupressure in addition to standard care, will reduce substantially compared to patients who received only routine treatment. This controlled trial was undertaken with hospitalized leukemia patients between February and June 2015. Our primary sample consisted of 100 participants who were randomly allocated to 2 groups. One (intervention) group underwent 12 acupressure sessions in addition to standard treatment while the control group received no intervention apart from being given the standard treatment for leukemia. The visual analogue scale was used to measure the levels of pain experienced. No significant differences were found between the 2 groups across 12 interventions. However, each group reported significantly different pain level changes before and after each intervention, suggested that the acupressure method was effective in reducing pain in the short term. Nurses are able to apply this complementary therapy alongside other procedures to manage these patients' pain. It is recommended that further studies be conducted to better understand the specific conditions under which acupressure can provide effective pain relief.

    PMID: 34408679 DOI: 10.3389/fpsyt.2021.692498
    Objective: The aim of this study was to translate and evaluate the validity and reliability of the Impact of Events Scale-Revised (IES-R) among the Iranian general population during the coronavirus disease 2019 (COVID-19) pandemic. Method: This study was methodological cross-sectional. It was conducted on an Iranian public population from April to July 2020 which was during the COVID-19 pandemic. Construct validity was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with a total of 500 adults recruited via online data gathering. Reliability was checked through the average inter-item correlation (AIC), Cronbach's alpha, and McDonald's omega. Convergent and divergent validity was determined using Fornell and Larcker's approach. Results: The results showed that the Persian version of IES-R had three factors, including intrusion (six items), avoidance (seven items), and hyperarousal (five items), that explained 59.22% of the total variance of the IES-R. The CFA findings indicated that all goodness-of-fit indices confirmed the model fit. The Cronbach's alpha, McDonald's omega, composite reliability (CR), and maximal reliability were excellent, and the three factors have good convergent validity. Conclusion: The findings of this study indicated that the Persian version of the IES-R scale is efficient and useful to assess post-traumatic stress disorder among Iran general population in the COVID-19 outbreak.
  13. Fulltext Psychometrics of Persian Version of the Ageism Survey Among an Iranian Older Adult Population During COVID-19 Pandemic
    Sharif Nia H, She L, Rasiah R, Khoshnavay Fomani F, Kaveh O, Pahlevan Sharif S, et al.
    Front Public Health, 2021;9:683291.
    PMID: 34869136 DOI: 10.3389/fpubh.2021.683291
    Background: Studies have revealed an increase in discrimination, neglect, and abuse among the older adult population during this period. This study assessed the validity and reliability of the Persian version of the ageism survey instrument tested on a sample of the Iranian older adult population during coronavirus disease (COVID-19) pandemic. An important move in counteracting ageism is to classify the ageism scale comprehensively by employing adequate psychometrics. Methods: The Persian version of the ageism scale was developed using a two-step procedure. The first step involved translating and revising the original scale to develop a Persian version of the ageism scale. The second step involved assessing the psychometric features of the newly adapted scale using construct validity through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and thereafter assessing the reliability through the average inter-item correlation (AIC), Cronbach's alpha. The sample consisted of 400 older adults (age 65 and older), who were recruited through online data collection, with samples for EFA and CFA randomly selected from the total samples. Results: The Persian version of the ageism survey has three factors: age-related deprivation with five items, dignity with three items, and employment with three items; all of which explained 57.02% of the total variance. The outcome of the EFA was verified by the CFA, with internal consistency reliability being excellent (Cronbach's alpha was 0.725, 0.698, and 0.708 for the three factors). Conclusion: This study specifically offers a restructured three factors Persian version of the ageism survey for Iranian older adults with acceptable construct validity and reliability.
  14. The Relationship between Religious Coping and Self-Care Behaviors in Iranian Medical Students
    Sharif Nia H, Pahlevan Sharif S, Goudarzian AH, Allen KA, Jamali S, Heydari Gorji MA
    J Relig Health, 2017 Dec;56(6):2109-2117.
    PMID: 28229351 DOI: 10.1007/s10943-017-0376-2
    In recent years, researchers have identified that coping strategies are an important contributor to an individual's life satisfaction and ability to manage stress. The positive relationship between religious copings, specifically, with physical and mental health has also been identified in some studies. Spirituality and religion have been discussed rigorously in research, but very few studies exist on religious coping. The aim of this study was to determine the relationship between religious coping methods (i.e., positive and negative religious coping) and self-care behaviors in Iranian medical students. This study used a cross-sectional design of 335 randomly selected students from Mazandaran University of Medical Sciences, Iran. A data collection tool comprised of the standard questionnaire of religious coping methods and questionnaire of self-care behaviors assessment was utilized. Data were analyzed using a two-sample t test assuming equal variances. Adjusted linear regression was used to evaluate the independent association of religious copings with self-care. Adjusted linear regression model indicated an independent significant association between positive (b = 4.616, 95% CI 4.234-4.999) and negative (b = -3.726, 95% CI -4.311 to -3.141) religious coping with self-care behaviors. Findings showed a linear relationship between religious coping and self-care behaviors. Further research with larger sample sizes in diverse populations is recommended.

    Sharif Nia H, Rezapour M, Allen KA, Pahlevan Sharif S, Jafari A, Torkmandi H, et al.
    Asian Pac J Cancer Prev, 2019 09 01;20(9):2803-2809.
    PMID: 31554380 DOI: 10.31557/APJCP.2019.20.9.2803
    Objectives: The Center for Epidemiologic Studies Depression Scale (CES-D) was specifically created to assess
    depression in cancer patients. However, to date, the CES-D has not been validated in Farsi. Therefore, this study aimed to
    assess the psychometric properties of the CES-D in Iranian cancer patients. Methods: During a three-month period
    (October to December, 2015), a total of 380 cancer patients completed a Farsi version of the CES-D. The construct
    validity of the scale was evaluated by exploratory factor analysis. Reliability was assessed using Cronbach’s alpha
    and McDonald Omega. All of the statistical procedure were run by SPSS 22 (SPSS Inc., Chicago, IL, USA). Results:
    The construct validity of the CES-D determined three factors (somatic affect, negative affect, and positive affect),
    which explained 65.60% of the total variance. The internal consistency was greater than 0.70. Conclusion: Findings
    revealed that the Farsi version of the CES-D has acceptable validity and reliability, which can be used to measure
    depression in Iranian cancer patients.
  16. Development and psychometric evaluation of a Persian version of the Death Depression Scale-Revised: a cross-cultural adaptation for patients with advanced cancer
    Sharif Nia H, Pahlevan Sharif S, Lehto RH, Boyle C, Yaghoobzadeh A, Kaveh O, et al.
    Jpn J Clin Oncol, 2017 Aug 01;47(8):713-719.
    PMID: 28505271 DOI: 10.1093/jjco/hyx065
    Objective: The surfacing of thoughts and depressive affect associated with the prospect of death are prevalent among patients with advanced cancer. Because death cognitions and associated negative affect occur along an adaptive-less adaptive continuum, it is essential that valid and reliable instruments are available to measure death depression. The present study aimed to determine the psychometric properties of the Death Depression Scale among Iranian patients with advanced cancer.

    Methods: About 497 cancer patients completed a Persian version of the 21-item Death Depression Scale-Revised. The face, content and construct validity of the scale were ascertained. Reliability was also assessed using internal consistency, construct reliability and intra-class correlation coefficient (ICC).

    Results: Construct validity determined one factor with an eigenvalue greater than 1. The model had a good fit (χ2 (179, N = 248) = 520.345, P < 0.001; χ2/df = 2.907, CFI = 0.916, TLI = 0.902, IFI = 0.917, SRMR = 0.049 and RMSEA = 0.088 (90% confidence interval = 0.079-0.097)) with all factors loadings greater than 0.5 and statistically significant. The internal consistency, construct reliability and ICC were greater than 0.70. Convergent validity of the scale was demonstrated.

    Conclusions: Findings revealed that the Persian version of the Death Depression Scale-Revised is valid and reliable, and may be used to assess and evaluate death depression in Iranian patients with advanced cancer.

    Pahlevan Sharif S, Lehto RH, Amiri M, Ahadzadeh AS, Sharif Nia H, Haghdoost AA, et al.
    Palliat Support Care, 2021 02;19(1):55-61.
    PMID: 32580795 DOI: 10.1017/S1478951520000383
    OBJECTIVE: This study investigated relationships among spirituality, hope, and overall quality of life in Muslim women with breast cancer in Malaysia.

    METHOD: A cross-sectional descriptive design with a convenience sample of 145 Malay patients was used. The mediating role of hope in the relationship between spirituality and quality of life as well as the moderating effect of education level on the spirituality hope link were examined.

    RESULTS: Participants with higher self-reported spirituality reported more hope (b = 6.345, p < 0.001) and higher levels of quality of life (b = 1.065, p < 0.001). Higher educational attainment weakened relationships between spirituality and hope (b = -1.460, p < 0.001).

    SIGNIFICANCE OF RESULTS: The role of advanced education in contributing to lessened hope in relation to spirituality emphasizes the importance of skilled and personalized spiritual counseling in the respective socio-cultural religious context.

  18. Fulltext Psychometric Properties of the Persian Version of Spiritual Well-Being Scale in Patients with Acute Myocardial Infarction
    Soleimani MA, Pahlevan Sharif S, Allen KA, Yaghoobzadeh A, Sharif Nia H, Gorgulu O
    J Relig Health, 2017 Dec;56(6):1981-1997.
    PMID: 27629419 DOI: 10.1007/s10943-016-0305-9
    The purpose of this study was to assess the psychometric properties of the Persian version of Spiritual Well-Being Scale (SWBS) in patients with acute myocardial infarction. A multisite, cross-sectional survey was employed to determine the instrument's reliability (Cronbach's α and construct reliability) and validity (face, content, and construct). Using systematic sampling of adult outpatients at primary care clinic sites in the Qazvin City, Iran (N = 300), it was found that the Cronbach's alpha and construct reliability of both factors associated with the SWBS were above 0.7. The construct validity of the scale was determined using exploratory factor analysis. The findings supported two factors: relation with God and relation with life. Further investigation through confirmatory factor analysis (eigenvalues of greater than one) confirmed a third factor construct associated with the SWBS. A total of 50.65 % of the variance were explained by these three factors. The overall findings of the study demonstrated that the SWBS is a valid and reliable instrument that has potential utility in future research and clinical practice settings.
  19. Fulltext Retaining nurses via organizational support and pay during COVID-19 pandemic: The moderating effect between intrinsic and extrinsic incentives
    Pahlevan Sharif S, She L, Liu L, Naghavi N, Lola GK, Sharif Nia H, et al.
    Nurs Open, 2023 Jan;10(1):123-134.
    PMID: 35906871 DOI: 10.1002/nop2.1286
    AIM: There has been growing concern about the nurses' turnover intention as well as life satisfaction during COVID-19 pandemic in Iran. The past research has provided evidence on the effect of organizational support on nurses' job satisfaction and turnover intention. However, little is known about the underlying mechanism behind these associations.

    DESIGN: A cross-sectional survey was undertaken.

    METHODS: An online survey was conducted in Iran from May to June 2020 through Google Docs Forms. In total, 305 nurses were participated and completed the online survey. Data were analysed using structural equation modelling through (AMOS). This study was checked with the STROBE checklist.

    RESULT: The results showed that nurses' perception of organizational support was positively related to their job satisfaction which in turn decreases the turnover intention. Likewise, the job satisfaction partially mediated the relationship between organizational support and nurses' life satisfaction.

    Sharif Nia H, Gorgulu O, Pahlevan Sharif S, Froelicher ES, Haghdoost AA, Golshani S, et al.
    Iran J Public Health, 2020 May;49(5):923-930.
    PMID: 32953680
    Background: The prevalence of Acute Myocardial Infarction (AMI) varies from region to region caused by seasonal climate changes and temperature variation. This study aimed to assess the relationship between changing meteorological conditions and incidence of AMI in Iran.

    Methods: This retrospective prevalence study was based on medical records of the heart center of Mazandaran Province on all patients diagnosed with AMI in Mazandaran, northern Iran between 2013 and 2015. Patients' sex and the day, month, year and time of hospital admission were extracted from patients' records. Moreover, the meteorological reports were gathered.

    Results: A statistically significant difference was found between the distributions of AMI cases across 12 months of the year (P < 0.01). Fuzzy clustering analysis using 16 different climatic variables showed that March, April, and May were in the same cluster together. The other 9 months were in different clusters.

    Conclusion: Significant increase in AMI was seen in March, April and May (cold to hot weather).
