Translation and psychometric evaluation of the Persian version of the nurses' quality of life scale: a validation study in Iran.

BACKGROUND: The quality of life for nurses can be significantly impacted by various occupational factors that Influence their working conditions and professional performance. The current study aimed to translate and validate the Persian version of the Nurses' Quality of Life Scale. MATERIAL AND METHOD: In this cross-sectional research, the Nurses' Quality of Life Scale (NQOLS) was utilized to assess the quality of life among 500 employed nurses in hospitals in the cities of Gonabad and Sabzevar. The translation process of the NQOLS followed the model proposed by Wild et al. The content validity of the Persian version of the scale was evaluated using the Content Validity Index (CVI) and Content Validity Ratio (CVR). Structural validity was assessed using exploratory and confirmatory factor analyses. Internal consistency reliability was assessed using Cronbach's alpha, while test-retest reliability was determined using the Intraclass Correlation Coefficient (ICC). Data analysis was conducted using SPSS version 26 and LISREL version 8.8 software. RESULTS: The exploratory factor analysis of the Persian version of NQOLS revealed six factors that accounted for 62.15% of the total variance. The structural validity of the extracted factors was confirmed through confirmatory factor analysis. The Cronbach's alpha coefficient and ICC for the entire questionnaire were 0.91 and 0.95, respectively. CONCLUSION: The findings of the present study suggest that the Persian version of the NQOLS exhibits sufficient validity and reliability. Therefore, it can be used as an effective tool for measuring and examining the quality of life among nurses in Iran.

Validation of the Persian version of family health climate scale (FHC-Scale) in Iranian families.

BACKGROUND: Family health is an important issue which has attracted researchers from different fields. The present study aimed to validate the Persian version of the Family Health Climate Scale (FHC-Scale). METHODS: In this methodological research, a total of 620 individuals presenting to Comprehensive Healthcare centers affiliated with Mashhad University of Medical Sciences and Gonabad University of Medical Sciences were selected through random multistage sampling. Validation of the FHC-Scale was performed. First, the original scale was translated and back-translated. Then its content validity and construct validity were assessed using exploratory and confirmatory factor analysis. Reliability was assessed using internal consistency and stability. Data were analyzed using SPSS version 20 (IBM Corp., Armonk, NY, USA) and LISREL version 8.5 (SSI Inc., Skokie, IL, USA). RESULTS: Results of exploratory factor analysis showed that "physical activity" of family health climate scale (FHC-PA) has three dimensions: value, cohesion and information explaining 61.99% of the variance. "Nutrition" of family health climate scale (FHC-NU) had four dimensions of value, communication, cohesion and consensus explaining 66.19% of the variance. Internal consistency of the dimensions of (FHC-PA) ranged 0.82-0.85 and that for FHC-NU ranged 0.82-0.84. Confirmatory factor analysis revealed goodness of fit and confirmed family health climate scale (Nutrition and physical activity). CONCLUSION: Results of the study revealed that the FHC-Scale has appropriate reliability and validity for Iranian families. Therefore, the Persian version of the scale can be used for assessing health-related aspects of family.

Menopause uncertainty: the impact of two educational interventions among women during menopausal transition and beyond.

INTRODUCTION: Menopause is a natural part of women's lives, which is associated with physical and mental changes and can lead to uncertainty and consequent undesirable effects in the lives of menopausal women. The present study was conducted to compare the impact of multimedia and booklet educational methods on the uncertainty about menopause during this transition period. MATERIALS AND METHODS: In a cluster randomized trial 68 women aged 45-55 years were randomly allocated into two groups: multimedia and booklet. Data were collected using knowledge and uncertainty questionnaires about menopause in three stages, i.e. before intervention, immediately after intervention (two weeks later), and one month later. Repeated-measures analysis of variance (rANOVA) was used to compare knowledge and uncertainty scores between two groups for the duration of the study. Data were analysed using SPSS software and p values < 0.05 were considered as statistically significant. RESULTS: The results of the study indicated a high level of uncertainty in both groups before the implementation of the educational program. There was no significant difference between groups in terms of knowledge and uncertainty about menopause over time (p > 0.05). However, we found a significant increase in knowledge and a significant decrease in uncertainty scores in both groups (p < 0.001) after the interventions. CONCLUSIONS: Although the findings of this study did not show a significant difference between the effect of multimedia and booklet educational methods in postmenopausal women, the high level of uncertainty of women before intervention and its significant reduction after the implementation of the educational programs indicated the importance of education throughout this period.

The relationship between management strategies for menopausal symptoms and women's decision making styles during menopausal transition.

INTRODUCTION: Considering the importance of identifying the factors affecting women's decision making process about the management of menopausal symptoms, this study was conducted with the aim of investigating the relation between decision making styles and women's chosen options for management of menopausal symptoms. MATERIAL AND METHODS: This cross-sectional study was conducted from May 2016 to July 2018 in Gonabad, north east of Iran.Using the cluster sampling method 473 women between 45 and 60 years old were recruited to the study. Data were collected using a demographic questionnaire, a menopause symptom treatment options questionnaire, the Menopause Rating Scale and the Decision Making Styles Questionnaire. The data analysis was conducted using SPSS software version 16 as well as descriptive and analytical statistics; a p-value of< 0.05 was considered as statistically significant. RESULTS: The mean age of participants was 51.6 ±4.6 years old and the majority of them (85.5%) were housewives. The most popular menopause symptom treatment option was hormone replacement therapy. The majority of participants (45.4%, 228 people) used an avoidant decision making style. There was no statistically significant difference between menopausal symptom treatment options and decision making styles type(p = 0.525). There was a statistically significant difference between severity of menopausal symptoms and type of decision making style (p = 0.003). CONCLUSIONS: The findings showed that there was no significant relation between the selected method to manage menopausal symptoms and women's decision making styles. It is recommended that this study be conducted on a population that has greater access to all menopausal symptom treatment options.

Structural Challenges of Providing Palliative Care for Patients with Breast Cancer.

INTRODUCTION: To establish a palliative care system (PCS) in Iran, it is necessary to identify the potential barriers. AIM: This study aims to highlight the views of stakeholders to know the challenges of providing palliative care for women with breast cancer. MATERIALS AND METHODS: Semi-structured in-depth interviews are used with purposeful sampling conducted in Tehran, Iran; from January to June 2015. Twenty participants were included in the study: nine patients with breast cancer and ten health-care providers. The interviews were analyzed using qualitative directed content analysis based on Donabedian model. Data credibility was examined using the criteria of Lincoln and Guba. RESULTS: Based on the pattern of Avedis Donabedian model, two main categories were identified: (1) palliative care services in the health system still remain undefined and (2) lack of adequate care providers. The subcategories emerged from the main categories are: (1) Inexistent home care, (2) specialized palliative care being in high demand, lack of: (a) Rehabilitation program and guidelines, (b) treatment/training protocols, (c) inefficient insurance and out-of-pocket costs, (d) patient referral system, (e) nontransparency of job description, and (f) weakness of teamwork. DISCUSSION: The findings of the study identify views and perceptions of patients as well as the health professionals around the challenges of providing palliative care. To establish a structured PCS, we need to meet the challenges and remove perceived barriers to, including but not limited to, building up knowledge and awareness of health professionals, educating professional, and developing updated, well-defined, and standard treatment protocols, tailored to local conditions.

The correlation between perceived social support and illness uncertainty in people with human immunodeficiency virus/acquired immune deficiency syndrome in iran.

BACKGROUND: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) (PLWH), and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. AIM: To examine uncertainty in PLWH and its correlation with social support in Iran. MATERIALS AND METHODS: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson's correlation coefficient, Spearman's correlation coefficient, and regression analysis. RESULTS: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty (P = 0.01, r = -0.29). CONCLUSION: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

Translation, cross-cultural adaptation, and validation of the Persian version of the Attitude Towards Menopause scale.

OBJECTIVES: This study describes translation, cross-cultural adaptation, and validation of the Attitude Towards Menopause (ATM) scale in Persian. METHODS: A standard process was followed for translation and cross-cultural adaptation of the ATM scale into Persian. The content validity index and content validity ratio were used to measure content validity. The construct validity was tested using exploratory factor analysis and confirmatory factor analysis. The average variance extracted and construct reliability were used to indicate convergent and discriminant validity, respectively. Internal consistency and test-retest reliability of the Persian ATM scale were assessed using Cronbach α and intraclass correlation coefficient (ICC). RESULTS: A revised version of the ATM scale, including 26 items assigned to seven factors, was obtained in exploratory factor analysis. The factors were interpreted as negative affect, postmenopausal recovery, control of symptoms, sexuality, psychological losses, unpleasant confrontation, and menstrual freedom, explaining 66.18% of the total variance. The factor structure of the scale was confirmed using confirmatory factor analysis (Comparative Fit Index = 0.90, Tucker-Lewis Index = 0.88, Goodness-of-Fit Index = 0.90, Adjusted Goodness-of-Fit Index = 0.86, Root Mean Square Error of Approximation = 0.07, χ2 / df = 4.56). The values of Cronbach α coefficient and ICC indicated an acceptable level of reliability ( α = 0.70, ICC = 0.89). The construct reliability for all factors was more than or equal to 0.7 except for psychological losses, indicating good discriminating validity. The values of average variances extracted for subscales varied from 0.48 to 0.99, representing adequate convergent validity. CONCLUSIONS: The Persian version of the ATM scale is a reliable and valid tool to evaluate the attitudes of Iranian women toward menopause.

Comparison of the Impacts of Benson Relaxation Technique and Foot Reflexology Massage on Sleep Quality of Patients with Systolic Heart Failure: A Randomized Clinical Trial.

Background: Cardiovascular diseases can affect sleep quality. The use of non-pharmacological methods to improve the sleep quality of heart failure patients is essential. Therefore, this study compared the effects of the Benson relaxation technique and foot reflexology massage on sleep quality of those patients. Materials and Methods: In this clinical trial study, 93 patients with systolic heart failure referred to Javad Al-Aeme heart clinic in Torbat Heydarieh were selected with purposive sampling method and divided into the foot reflexology massage, Benson relaxation technique, and control groups using the balanced blocking randomization method. The Benson relaxation technique and the foot reflexology massage were performed for 20 and 30 minutes three days per week for four weeks, respectively. The control group only received routine care. Sleep quality was measured by the Pittsburgh sleep quality index and then compared among the groups before and after the intervention. The data were analyzed using ANOVA, Tukey's post hoc tests, paired t test, and Chi-square at the significant level of p < 0.05. Results: After interventions, the mean (SD) quality of sleep significantly increased in both intervention groups (Reflexology: pre-intervention 10.80 (3.40), post-intervention 6.60 (3.10), Benson relaxation: pre-intervention 15.50 (2.40) post-intervention 12 (2.60), compared to the control group (pre-intervention 10.50 (1.90) post-intervention 9.40(1.70) (p < 0.001). There was no significant difference between the two intervention groups (p = 0.53). Conclusions: The interventions improved the quality of sleep in patients with systolic heart failure. Therefore, these methods can be used as a suitable complementary treatment to improve the quality of sleep by nurses and midwives.

Comparing Effects of Rhythmic Breathing and Lidocaine Spray on Pain Intensity During Needle Insertion Into Arteriovenous Fistula in Hemodialysis Patients: A Randomized Controlled Trial.

Background: Hemodialysis patients suffer from pain caused by needle insertion into the fistula site. Non-pharmacological methods may be associated with acceptable effects. Objectives: The present study aimed to compare the effects of two interventions on pain intensity during needle insertion into the arteriovenous fistula in hemodialysis patients. Methods: This self-controlled, single-blind clinical trial was conducted on 54 hemodialysis subjects with arteriovenous fistula in Mashhad in 2021. In this regard, the patients were selected according to the inclusion criteria and randomly assigned to two groups (lidocaine spray and rhythmic breathing). In each group, pain intensity was assessed based on the visual analogue scale (VAS) before the intervention, followed by measuring the post-intervention pain intensity during three consecutive hemodialysis sessions every other day. Regarding the lidocaine spray group, two puffs of 10% lidocaine spray (20 mg) were sprayed on the needle insertion site five minutes before cannulation. However, the patients in another group took a long deep breath through the nose with three numbers, held their breath in the lungs for three numbers, and slowly exhaled through the mouth with three numbers two minutes before cannulation. The data were analyzed using SPSS software version 20, and Mann-Whitney U, Wilcoxon, chi-squared, and paired t-tests were run. In this study, P < 0.05 was considered significant. Results: The results represented a significant decrease in the pain severity scores of both rhythmic breathing (P = 0.023) and lidocaine spray (P < 0.001) groups after the intervention. Moreover, a more significant difference was observed between pre-and post-intervention pain intensity scores in the group treated with lidocaine spray (1.16 ± 1.56) compared to the other group (0.508 ± 1.25). Conclusions: The lidocaine spray group had a larger difference in the pre-and post-intervention pain intensity scores than the rhythmic group; however, the difference was not significant. The rhythmic breathing can be used by nurses as a non-pharmacological method with low complications in hemodialysis departments because of declining pain.

Evaluation of the effects of diabetes self-management education based on 5A model on the quality of life and blood glucose of women with gestational diabetes mellitus: an experimental study in eastern Iran.

Introduction: Gestational diabetes mellitus (GDM) is an important condition during pregnancy. The aim of the current study was to evaluate the effects of self-management education based on 5A model on the quality of life and blood glucose level of women with GDM. Methods: This quasi-experimental study was conducted on 54 pregnant women referred to the urban health care centers affiliated to the Gonabad University of Medical Sciences from March 2019 to March 2020 based on purposive sampling method. Participants were randomly allocated into intervention and control groups based on stratified random sampling using permuted block randomization method. The intervention group received self-management education program based on 5A model in five sessions during two months. Demographic data, blood glucose level, and diabetes quality of life (DQOL) questionnaire were collected for each participant. Data analysis was performed using the SPSS software version 16 and the level of statistical significance was set at 0.05. Results: Mean age of the participants was 33.11 ± 5.35 years old. At the end of the intervention, the mean blood glucose level of the participants in the intervention group was significantly lower compared to the control group (p < 0.001). The quality of life in the intervention group was significantly improved at the end of the intervention compared to the control group (p < 0.001). Conclusions: Self-management education based on 5A model can effectively improve quality of life and blood glucose levels in women with GDM.

Validation of the Persian version of self-care tools for hypertension among older adults.

Aim To validate two sub-scales of self-care behaviour and self-efficacy of hypertension in elderly patients in Iran using an English scale developed by Dr. Han et al. Methods The Persian version of two sub-scales of self-care behavior and self-efficacy was validated for 300 elderly people who suffered from hypertension. These sub-scales were translated into Persian according to the Wild et al. model. The validity of the tool was confirmed through formal, content and structural validity and reliability through calculation of internal consistency and time stability. Results Cronbach's alpha was reported to 0.85 for behavior, 0.86 for self-efficacy. Pearson's correlation coefficient for behavior was 0.89, for self-efficacy 0.92. Intraclass correlation coefficient (ICC) was 0.84 for behavior and 0.88 for self-efficacy. The minimum acceptable content validity ratio (CVR) for each grade was equal to 49.0 and for the content validity index (CVI) equal to 0.79, indicating that all items obtained the grade points. In exploratory analysis, two dimensions of diet and disease management were determined for both sub-scales, which were approved according to fit indicators. Conclusion The Persian version of the Self-Care Tools for hypertension showed favourable validity and reliability, and thus it can be used for measuring the level of self-care for hypertension in Iranian elderly population.

Evaluation of Health-Care Providers' Perception of Spiritual Care and the Obstacles to Its Implementation.

OBJECTIVE: Cancer patients face many health challenges, including spiritual issues. Therefore, an awareness of health-care providers' perspective on spiritual care provision is important. This study aimed to determine health-care providers' perception of spiritual care and to examine the individual barriers to its implementation in cancer patients. METHODS: The present descriptive study included 136 physicians and nurses. The Spiritual Care Survey was used as a research tool. Data were analyzed through descriptive statistics using IBM SPSS Statistics for Windows, version 20.0. RESULTS: In this study, 70.6% of the participants considered spiritual care to be influential in the patients' quality of life. However, 64.7% had received no spiritual care training, while 82.4% indicated a willingness to attend these courses. Regarding the obstacles to providing spiritual care, the highest and lowest scores, respectively, belonged to the lack of time and the person's reluctance to talk about spiritual issues. CONCLUSIONS: Spiritual care has not yet found its proper place in the care setting of Iran, and health-care team members do not have sufficient training to provide this kind of care despite their belief in its positive impact on patients' quality of life.

The Effect of Education on the Attitude and Child Abuse Behaviors of Mothers with 3-6 Year Old Children: A Randomized Controlled Trial Study.

BACKGROUND: Child abuse is a kind of domestic violence of children under the age of 18 which potentially or actually damages all aspects of their health. This study was conducted to determine the effect of education based on growth and development with home-visiting follow up on the mothers' attitude and child abuse with 3-6-year-old children. METHODS: This controlled trial study was carried out in two rural community health centers in Khorasan Razavi province in Iran, during April 2016 to Jun 2017 on 64 abusive mothers of 3-6-year-old children. The data collection tools included the 32-item adult adolescent parenting inventory (AAPI) and the questionnaire of child abuse. By using multi-stage random sampling, the mothers referring to two health centers were assigned to the experimental (N=32) and control groups (N=32). The intervention group received parenting educational interventions based on child growth and development and after being followed up for eight weeks through home-visits. The data were analyzed in SPSS-16, using descriptive statistics, analytical tests including the Chi-square, independent t-test, and Mc Nemars test. RESULTS: After the intervention, the overall score of parenting attitudes was found to be significantly increased (P<0.001), and the prevalence of most abusive behaviors towards children was significantly reduced (P<0.05) in the intervention group compared to the control group. CONCLUSION: According to the results, this educational program was found to be significantly more effective in improving parenting attitudes and preventing child abuse compared to routine childcare programs in health centers. Trial Registration Number: IRCT2016052628094N1.

Palliative Care in Iran: Moving Toward the Development of Palliative Care for Cancer.

Cancer is the third leading cause of death in Iran and its incidence has been increasing in recent years. Patients' quality of life is altered rather enormously due to cancer, which doubles the importance of and the need for providing palliative care in Iran. Although many steps have been taken toward the development and providing of palliative care in Iran, there is still a large gap between the status quo and the desirable state. This study presents the current state of palliative care for cancer patients and discusses the barriers, challenges and outlook of palliative care in Iran. If infrastructural projects that have recently been launched prove successful, proper advancement toward the providing of palliative care services in Iran will then not far on the horizon.

Psychometric Properties of the Persian Version of Self-Transcendence Scale: Adolescent Version.

BACKGROUND: Given the greater tendency during adolescence toward risk-taking, identifying and measuring the factors affecting the adolescents' health is highly important to ensure the efficacy of health promoting interventions. One of these factors is self-transcendence. The aim of this study was to assess the psychometric features of the Self-Transcendence Scale (adolescents' version) in students in Tehran, the capital city of Iran. METHODS: This research was conducted in 2015. For this purpose, 1210 high school students were selected through the multistage cluster sampling method. After the backward-forward translation, the psychometric properties of the scale were examined through the assessment of the (face and construct) validity and reliability (internal consistency and stability) of the scale. The construct validity was assessed using two methods, factor analysis, and convergence of the scale with the Hopefulness Scale for Adolescents. RESULTS: The result of face validity was minor modifications in some words. The exploratory factor analysis resulted in the extraction of two dimensions, with explaining 52.79% of the variance collectively. In determining the convergent validity, the correlation between hopefulness score and self-transcendence score was r=0.47 (P<0.001). The internal consistency of the scale was determined using Cronbach's alpha of 0.82 for the whole scale and 0.75 and 0.70 for each of the sub-scales. The stability reliability was found to have an ICC of 0.86 and a confidence interval of 95%. CONCLUSION: The Persian version of the Adolescents' Self-Transcendence Scale showed an acceptable validity and reliability and can be used in the assessment of self-transcendence in Iranian adolescents.

The effects of menopausal health training for spouses on women's quality of life during menopause transitional period.

OBJECTIVE: Spouses' support during menopausal transition has an important role for improving the quality of life in postmenopausal women. Since the first step in providing support is having adequate knowledge, this study aimed to investigate the effects of an educational program on menopause health for spouses on women's quality of life during the menopausal transition. METHODS: This clinical trial was conducted in Yazd, Iran. A hundred healthy women aged 45 to 60 years were recruited by random sampling. The spouses in the intervention group (n = 50) attended three training sessions about the management and health of menopausal transition. The spouses in the control group (n = 50) did not receive any intervention. Knowledge and performance about menopausal health were assessed in all spouses before and 3 months after intervention. All women were assessed by the Menopause Rating Scale, and the Menopause Quality of Life questionnaire before and 3 months after educational intervention. Analyses were carried out using SPSS 16 software. The level of significance was set at P less than 0.05. RESULTS: The knowledge and performance of spouses in the intervention group were significantly higher 3 months after intervention (P < 0.0001). The quality of life in women in the intervention group was higher 3 months after intervention (P < 0.0001). The mean scores of psychological and physical domains were significantly lower in the intervention group (P = 0.002 and P = 0.001, respectively). CONCLUSIONS: The training of menopausal health for spouses improves the quality of life in women during menopausal transition. We suggest integrating such educational programs in menopausal management programs.

Lived Experiences of "Illness Uncertainty" of Iranian Cancer Patients: A Phenomenological Hermeneutic Study.

BACKGROUND: For cancer patients, uncertainty is a pervasive experience and a major psychological stressor that affects many aspects of their lives. Uncertainty is a multifaceted concept, and its understanding for patients depends on many factors, including factors associated with various sociocultural contexts. Unfortunately, little is known about the concept of uncertainty in Iranian society and culture. OBJECTIVES: This study aimed to clarify the concept and explain lived experiences of illness uncertainty in Iranian cancer patients. METHODS: In this hermeneutic phenomenological study, 8 cancer patients participated in semistructured in-depth interviews about their experiences of uncertainty in illness. Interviews continued until data saturation was reached. All interviews were recorded, transcribed, analyzed, and interpreted using 6 stages of the van Manen phenomenological approach. RESULTS: Seven main themes emerged from patients' experiences of illness uncertainty of cancer. Four themes contributed to uncertainty including "Complexity of Cancer," "Confusion About Cancer," "Contradictory Information," and "Unknown Future." Two themes facilitated coping with uncertainty including "Seeking Knowledge" and "Need for Spiritual Peace." One theme, "Knowledge Ambivalence," revealed the struggle between wanting to know and not wanting to know, especially if bad news was delivered. CONCLUSION: Uncertainty experience for cancer patients in different societies is largely similar. However, some experiences (eg, ambiguity in access to medical resources) seemed unique to Iranian patients. IMPLICATIONS FOR PRACTICE: This study provided an outlook of cancer patients' experiences of illness uncertainty in Iran. Cancer patients' coping ability to deal with uncertainty can be improved.

Validity and reliability of the Persian version of the Brief Aging Perceptions Questionnaire in Iranian older adults.

BACKGROUND: Perceptions of aging refer to individuals' understanding of aging within their sociocultural context. Proper measurement of this concept in various societies requires accurate tools. OBJECTIVE: The present study was conducted with the aim to translate and validate the Brief Aging Perceptions Questionnaire (B-APQ) and assess its psychometric features in Iranian older adults. METHOD: In this study, the Persian version of B-APQ was validated for 400 older adults. This questionnaire was translated into Persian according to the Wild et al's model. The Persian version was validated using content, face, and construct (using confirmatory factor analysis) validities, and then its internal consistency and test-retest reliability were measured. Data were analyzed using the statistical software programs SPSS 18 and EQS-6.1. RESULTS: The confirmatory factor analysis confirmed construct validity and five subscales of B-APQ. Test-retest reliability with 3-week interval produced r=0.94. Cronbach's alpha was found to be 0.75 for the whole questionnaire, and from 0.53 to 0.77 for the five factors. CONCLUSION: The Persian version of B-APQ showed favorable validity and reliability, and thus it can be used for measuring different dimensions of perceptions of aging in Iranian older adults.

Psychometric properties of the Persian version of the Mishel's Uncertainty in Illness Scale in patients with cancer.

PURPOSE: Uncertainty is a major component in the illness experiences which extraordinarily can affect the psychological adjustment and the illness outcomes. Uncertainty in illness is defined as inability to define the illness-related events to the illness or disability in predicting the illness outcomes. The present study aimed to translate the Persian version of Uncertainty in Illness Scale (MUIS-A) and to investigate its psychometric properties on patients with cancer. METHOD: In this methodological study, validation of the Persian version of MUIS-A was performed in Iran on 420 cancer patients attending two major hospitals in Tehran, Iran. The scale was translated into Persian and back translated into English and revised according to editorial comments of the scale designers. Then, content and face validity, construct validity, internal consistency reliability and stability of the Persian version were measured. Data were analyzed using SPSS version 16 and LISREL 8.5. RESULTS: Mean of the participants MUIS-A score was 90.1 (16.8). Confirmatory factor analysis confirmed validity of the whole instrument and its four subscales. The consistency of the instrument with a three-week interval was r = 0.91. Cronbach's alpha was 0.89 for the whole scale of 32 MUIS-A items and α = 0.58-0.86 for its four factors. CONCLUSIONS: The Persian version of the MUIS-A has good psychometric properties. It can be used to assess uncertainty in illness in Iranian patients with cancer.
