The Concerns of Community-Dwelling Older Women Living with Urinary Incontinence: Qualitative Research.

INTRODUCTION AND HYPOTHESIS: The world including Iran is facing population aging. Urinary incontinence (UI) is one of the most common health concerns of older women that can be accompanied by an increased sense of loneliness, social restrictions, and disruption in activities of daily living in addition to the regular challenges of old age. This study was aimed at explaining the concerns of community-dwelling older women living with UI. METHODS: This study used the conventional, qualitative, content analysis approach with purposive sampling. Twenty interviews were conducted with 18 participants, including 15 community-dwelling older women with UI and three family members (a husband and two daughters), over the span of 14 months (from August 2021 to October 2022). The data were collected via semi-structured, face-to-face interviews until data saturation was achieved, and were analyzed using Graneheim and Lundman's method. RESULTS: The findings revealed that the concerns of older women with UI include the impasse of UI, being powerless in life, distorted social identity, and marital frustration, which fell under the main theme of sense of inadequacy. CONCLUSIONS: Recognizing the concerns of older women with UI can make health care teams more sensitive to the importance of resolving these concerns and can offer some insight into how best to provide targeted training, support, and counseling services at individual, family, and society levels, to eventually resolve the older adult's sense of inadequacy.

Determinants of Continuance Intention to Use Hearing Aids among Older Adults in Tehran (Iran).

The present study seeks to evaluate the factors determining the continuance intention to use hearing aids in older adults. This cross-sectional study was carried out in 2021. The technology post-acceptance model (PAM) framework was used to develop a model for the continuance intention to use hearing aids. In total, 300 hearing aid users aged ≥60 years, who were selected via a randomized stratified sampling method, completed the self-evaluation tools used in this study. With a mean age of 71.38 years (SD = 8), the participants comprised 50.7% and 49.3% females and males, respectively. The path analysis results showed that the continuance intention to use hearing aids was positively and significantly influenced by the actual use of hearing aids, the perceived benefits, satisfaction, confirmation, self-efficacy in using hearing aids, an extraverted personality trait, self-perceived hearing handicap, and perceived social support. The main results of the present study can help hearing care providers develop a better understanding of older users to design effective rehabilitation strategies and ensure their continuance intention to use hearing aids.

Prevalence and associated factors of mild cognitive impairment among middle-aged and older adults: Results of the first phase of Ardakan Cohort Study on Aging.

Background and Aims: Data on mild cognitive impairment (MCI) in low- to middle-income countries are still being determined, despite the fact that most future older adults are expected to reside in these regions. This study aimed to investigate the prevalence and associated factors of MCI in Iran. Methods: A cross-sectional study was conducted on 4938 community-dwelling subjects aged 50 years or above in the first wave of the Ardakan Cohort Study on Aging. MCI was evaluated using the Mini-Mental State Examination (MMSE) and the Abbreviated Mental Test Score (AMTS) in literate and illiterate individuals. The relationship between factors associated with the odds of MCI was assessed through logistic regression. Results: The prevalence of MCI among all participants, the literates and illiterates, was 15.8%, 6.3%, and 36.4%, respectively. It was found that failure to accomplish any of the MMSE or AMTS items was significantly related to MCI (p < 0.001). Age ([odds ratio (OR): 1.05; p < 0.001 in the literates], [OR: 1.06; p < 0.001 in the illiterates]), sex (OR: 0.13; p < 0.001 in the illiterates), history of stroke ([OR: 2.86; p = 0.006 in the literates], [OR: 2.04; p = 0.045 in the illiterates]), and depression ([OR: 1.87; p < 0.001 in the literates], [OR: 1.41; p = 0.008 in the illiterates]) were significantly associated with MCI. Conclusion: This study highlights the significant associations between age, education, depression, stroke, and MCI in Iranian participants. These findings emphasize the need for targeted interventions in low-literacy populations, mental health screening, and stroke prevention strategies to mitigate the burden of MCI and enhance cognitive health.

Comparing the Diagnostic Value of Four Dementia Tests in the Amnestic and Healthy Elderly.

Introduction: This study aimed to compare the diagnostic value of four questionnaires for the diagnosis of neurocognitive disorders (NCDs) in the elderly. Methods: In this project, people older than 60 years who lived in Tehran were investigated. A total of 99 literate cases were enrolled in the study, and four questionnaires, including functional assessment staging tool (FAST), abbreviated mental test score (AMTS), mini-mental state examination (MMSE), and modified Persian test of elderly for assessment of cognition and executive function (PEACE) were completed for them. They were then referred to a neuropsychiatrist, and the status of their cognition and neurobehavior was determined. The specialists were blinded to the results of the tests. Results: Of the 99 participants studied, 39 cases were healthy, eight cases had mild Alzheimer's disease, 38 had amnesic MCI, five cases had secondary dementia, and nine cases had mixed vascular dementia and Alzheimer's disease. The area under the ROC curve for distinguishing the healthy group from the rest of the population was 0.692, 0.629, 0.734, and 0.751 for the FAST, AMTS, MMSE, and NBCSS questionnaires, respectively. Conclusion: MMSE and NBCSS tests had better diagnostic power than the other two tests to distinguish the healthy group from the rest of the population.

Factors Associated with Medication Adherence in Elderly Individuals with Tuberculosis: A Qualitative Study.

Methods: This qualitative study was conducted in two phases, using an integrative literature review and individual interviews. Studies were gathered without time restriction from MEDLINE databases, Institute for Scientific Information (ISI), Google Scholar, Scopus, and EMBASE, as well as national databases, including Scientific Information Database and Magiran. The findings of 38 studies that met the inclusion criteria were analyzed through the conventional content analysis method based on the ecological approach. After reviewing and forming the data matrix, purposive sampling was performed among healthcare professionals, elderly tuberculosis patients aged 60 and over, and family caregivers of elderly patients to conduct individual interviews. Data obtained from 20 interviews were analyzed using the directed content analysis method. After coding, the data from individual interviews were entered based on similarity and difference in the categories of data matrix obtained from the literature review. Results: In general, the aforementioned codes were placed in four main categories, including individual factors (i.e., biological factors, affective-emotional factors, behavioral factors, cognitive factors, tuberculosis-related factors, and economic factors), interpersonal factors (i.e., patient's relationship with treatment team and family-related factors), factors related to healthcare service provider centers (i.e., medical centers' facilities and capacity building in healthcare service provider), and extraorganizational factors (i.e., social factors and health policymaking). Conclusion: The results of this study showed that medication adherence in elderly patients with tuberculosis was a complex and multidimensional phenomenon. Therefore, society, policymakers, and healthcare providers should scrutinize the factors affecting medication adherence in this group of patients to plan and implement more effective interventions.

The Challenges of Caring for an Adult Child with Schizophrenia in the Family: An Analysis of the Lived Experiences of Older Parents.

The present study aimed to investigate the lived experiences of older parents regarding the challenges in caring for adult children with schizophrenia. The current study was conducted on 16 parental (mother or father) caregivers of adult children with schizophrenia using a descriptive phenomenological qualitative approach and Colaizzi's seven-step method. This study follows the Qualitative Research Checklist (COREQ). The findings showed that the parent caregivers' experiences could be classified into two main themes: "burden of care" and "Negative attitude and inefficient performance." The former consisted of three sub-themes including "disrupted social and family interactions," "helplessness and inefficient support," and "challenges of the healthcare system," while the latter had two sub-themes including "Negative attitude and inefficient performance of the caregivers" and "Negative attitude and inefficient performance of families and society." Older parents have to tolerate a significant burden of care due to their age and physical conditions. Improving the knowledge of specialists, the government's redoubled efforts in multifaceted support for patients and caregivers, creating an integrated team of specialists, and accepting and improving public attitudes against stigma and obvious discrimination in society as important priorities in improving the condition of caregivers and patients with schizophrenia were considered.

The spousal role of middle-aged Iranian women: A qualitative content-analysis study.

This study aimed to explain the spousal role in the lives of Iranian middle-aged women. This qualitative study was conducted in Iran from July 2018 to November 2019. The participants included 25 middle-aged women selected through purposive sampling. The data were collected using semi-structured interviews and analyzed through conventional content analysis. The theme of reviving the spousal role was explained by three main categories of paying more attention to the spouse's needs, enhancing feminine charms, and maintaining married life. A deeper understanding of the middle-aged women's spousal role may help health-care personnel to develop indigenous marriage-enrichment programs for middle-aged individuals.

Weaving a cocoon on the way to aging transcendence: Grounded theory study on aging perception during menopause transition.

During menopause, women experience major changes, including the onset of aging as a natural and inevitable event. The present study aimed to explore and explain the process of aging perception during menopausal transition. This study was a qualitative grounded theory research, which was going to be implemented in 2019-2020 on 18 Baluch women settled in the Sistan & Baluchestan province in South-East Iran and among midlife or older menopause experienced women. Sampling was started first by Purposive sampling, and then it was performed with theoretic sampling. Data analysis was performed according to Corbin and Straus's approach (2015) in four phases: (1) identifying and developing concepts; (2) analyzing data for the context; (3) entering the process stage into analysis; and (4) integrating categories to build a theory. In this study, seven main categories were obtained: "Sunset of youth", "aging as the other side of the coin of menopause", "Weaving a cocoon", "aging as a mental trap", "social acceptance", "aging domino", and "feeling of transcendence". It seems that menopause plays an important role in Baluch women's view toward aging. The practical results of this study can be applied to better understand the middle-aged and older Baluch women's attitudes toward aging. Also study shows a new evolutionary and situational perspective on the lives of middle-aged menopausal Baluch women. Baluch women in menopause accept the sunset of youth and look forward to experiencing the Feeling of transcendence. Identify and respond to their needs by developing and establishing health policies to change their negative attitudes.

Psychometric properties of the Persian version of the "Intergenerational relationship quality scale for aging parents and their children".

BACKGROUND: Investigating the status of intergenerational relationships of elderly parents with their adult childen is very important in examining issues related to the status of the elderly such as well being and quality of life and other aspects of elderly life. Giveeen the significance of the topic, the current study aimed to examine the psychometric properties of the Persian version of "Intergenerational Relationship Quality Scale for Aging Parents and Their Children" (IRQS-AP). MATERIALS AND METHODS: A total of 463 community-dwelling elders (aged 60 years or older) in Tehran participated in this study through multistage cluster sampling method. To investigate reliability, the construct and convergent validity of the IRQS-AP, confirmatory factor analysis (CFA), and interclass correlation coefficient were done. RESULTS: The content validity index was 0.84 for the entire tool. In the CFA, we found the instrument had a four-factor structure and adequate internal consistency. The scale had a significant and positive correlation with the two measures of loneliness and depression. Furthermore, Cronbach's alpha was estimated at 0.77, and the high value of the interclass correlation was 0.82. CONCLUSION: The IRQS-AP is a valid and reliable scale that can be used to examine the status of intergenerational relationship quality in Iranian elder population.

Facilitators and barriers for families caring for adults living with Alzheimer's dementia: A qualitative study.

This study investigates the barriers and promoters of caring for older adults living with Alzheimer's Dementia (AD) in families. This was a qualitative study through content analysis (based on the Granheim and Lundman method), and the participants were selected using purposive sampling from the families of older adults living with AD who were receiving care in the community. We used semi-structured interviews to collect data from 32 family members. The validity and reliability of the data were assessed using the Lincoln and Guba criteria. In this study, 70.58% of primary caregivers were women. Caregiving facilitators included "Efficient family," "Capable caregiver," and "Motivated caregiver." Caregiving barriers included "Lacking awareness and knowledge," "Vulnerable family," "Older person with complex/multiple needs," and "Lack of care infrastructures." Training families and caregivers and developing care infrastructures for older adults with AD can help reduce caring barriers in older adults.

Effect of "Mehrpishegan" web-based support group on depression, anxiety, and stress among elderly informal caregivers: a protocol for a randomized-controlled trial.

BACKGROUND: Elderly population in low- and middle-income countries is rapidly growing, which indicates an increase in the number of dependent people needing long-term care. Caring for the elderly is difficult and stressful and threatens physical and mental health of informal caregivers. We aim to design a web-based support group and assess its effectiveness on depression, anxiety, and stress among elderly informal caregivers. METHODS: This is a protocol for a two-arm randomized controlled trial. A total of 160 informal elderly caregivers will be recruited from the southern area of Tehran. Eligible participants will be randomly allocated to two intervention and control groups. The inclusion criteria include not receiving salary for caring, having primary responsibility for care, having smartphone/tablet/computer, being able to use the contents and web applications, having at least one month of experience in caring for the elderly, and having access to the Internet at least once weekly. The intervention will be implemented by giving an account access to the designed website. Depression, anxiety, and stress will be assessed using the DASS21 questionnaire at baseline, and at the end of third and sixth months. DISCUSSION: Our findings can pave the way for improving the mental health of informal caregivers of the elderly through provision of web-based supportive services. This study stands as an opportunity to address the needs of caregivers and help them support each other in a novel way. TRIAL REGISTRATION: Iran Randomized Clinical Trial Center IRCT20201012048999N1 . Registered on 25 December 2020 (current status: ongoing). The World Health Organization Trial Registration Data Set is in Additional file 1 PROTOCOL VERSION: Second version 2021-05-27.

Raising Adolescent Children as a Developmental Task of Iranian Middle-aged Mothers: A Qualitative Study.

Background: Most parents consider adolescence to be the most difficult stage of parenting. Parental practice is a determining factor in adolescents' outcomes. Mothers play the main role of parenting in Iran. Coinciding the transition of adolescence with the transition of middle-aged mothers can affect the mothers' parenting practice. The present study aimed at explaining the Iranian mothers' practice in parenting an adolescent child. Methods: This qualitative conventional content analysis was conducted from July 2018 to November 2019 in Kashan. 21 in-depth semi-structured interviews with mothers of adolescent children were performed using a purposive sampling method. The data were analyzed through conventional content analysis. Data collection and analysis were performed simultaneously using MAXQDAv10 software. Results: Regarding the study objectives, two themes and six main categories were identified. The theme of 'laying the groundwork for upbringing' was detected by two main categories: 'meeting the needs and 'effective interaction with the adolescent'; also, the theme of 'individual-social capacity building' was explained by four main categories: 'helping to gain independence', 'modeling individual-social behavior', 'socializing the adolescent', and 'preparing to accept future roles'. Conclusion: Mothers' practice was mainly focused on adolescents' independence, college education, career prospects, and marriage preparation and respect for older adults. Consistent with this transition to modernity, and contrary to the collectivist values of Iranian society, mothers' practice was in line with developing adolescents' independence and building their self-confidence, which is close to the authoritative parenting style.

Development and validation of the geriatrics health behavior questionnaire (GHBQ).

BACKGROUND: Considering the importance of health behaviors in health outcomes, it is necessary to assess health behaviors precisely. This study aimed to develop and validate The Geriatrics Health Behavior Questionnaire among Iranian older adults. METHODS: This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The initial questionnaire has been developed with 22 items and seven subscales based on an extensive literature review, evaluation of related questionnaires, and experts' opinions. Face and content validity were evaluated by interviewing 10 older adults and 18 specialists. The construct validity was evaluated via Known-groups validity and convergent validity. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability. RESULTS: The face validity was conducted by using interviews with older adults and gathering the specialists' opinions. The items were grammatically and lexically corrected accordingly. Two items were deleted due to CVR < 0.44. Modified Kappa statistic (K*) and I-CVI for all items were higher than 0.88. The average content validity index (S-CVI/Ave) value was 0.94. Three items were deleted to improve the internal consistency; the final GHBQ consisted of 17 items with Cronbach α = 0.72. Acceptable convergent validity was approved by a significant correlation between GHBQ and SF8™ health survey (r = 0.613, P value< 0.001). Independent t-test showed that older adults with education level ≥ high school have significantly higher health behavior scores than those with education level < high school (11.93 ± 2.27 vs. 9.87 ± 2.35, t = - 9.08, p < 0.001). Intra-class correlation coefficient (ICC) for the total questionnaire was 0.92 (95% CI =0.84 to 0.96). Standard Error Measurement (SEM) and Minimal Detectable Change (MDC95) were 0.71 and 1.98, respectively. CONCLUSION: The present study results showed that the Geriatrics Health Behavior Questionnaire had suitable validity and reliability among Iranian older adults. It is recommended to consider its comprehensiveness and yet its briefness in other populations after passing validation.

Barriers to home care for older adults from perspectives of Iranian informal caregivers: a qualitative study.

OBJECTIVE: A longer life expectancy increases the number of older adults who require long-term care. The presence of a caregiver at home prevents the placement of older adults in care facilities. Identifying the caregivers' viewpoints around the care clarifies key factors in providing quality care.This study aimed to assess barriers to home care from the perspective of Iranian informal caregivers of older adults. DESIGN: This was a qualitative study with content analysis. Semistructured interviews were conducted via telephone in Persian with informal caregivers of older adults using open-ended questions. SETTING: Social and health organisations in southern Tehran, Iran. PARTICIPANTS: Seventeen informal caregivers were selected on purpose. Participants were eligible to participate in the study if they were 18 years or older, and had at least 1 month of care experience for a minimum of 6 hours per week. RESULTS: Barriers to home care for older adults from informal caregivers' points of view were categorised into three domains: (1) Individual barriers include the physical, mental and social burden of care as well as personal characteristics of the caregiver; (2) interpersonal barriers include psychobehavioural characteristics of the older adult and misbehaviour of people around the caregiver and (3) care system barriers include inefficient institutional/organisational infrastructure, moral issues and inefficiency in public policy. CONCLUSIONS: Our study showed multiple individual, interpersonal and care system barriers to home care for older adults. Specific contextual challenges among Iranian caregivers, such as their attitudes and beliefs, as well as a lack of social and healthcare support for families, hindered the quality of care. TRIAL REGISTRATION NUMBER: IRCT20201012048999N1.

Attentional network changes in subjective cognitive decline.

BACKGROUND: Subjective cognitive decline (SCD) is known as the intermediate stage between normal cognitive aging and mild cognitive impairment (MCI). Although elderly with SCD usually perform close to normal in standardized tests, the detailed function of attention networks in this group has not been studied yet. AIMS: The purpose of this study was to investigate the performance of attention networks, as a possible indicator of cognitive disorder, in older individuals with subjective memory complaint and MCI. METHOD: The attention network test (ANT) was used to examine and compare the performance of three attention networks of alerting, orientation, and executive control in 17 elderly with SCD, 30 multiple domain amnestic MCI subjects, and 15 healthy controls. RESULTS: Although the orienting network had almost the same performance in all groups (p = 0.25), the performance of alerting (p = 0.01) and executive control networks (p = 0.02) were significantly different among the three groups: the SCD group performed poorly in both networks compared with the controls and did not differ significantly from the MCI group (p ≥ 0.05). However, controlling for general age-related slowing abolished the group difference in executive control index. More importantly, our results showed that alerting network that was affected in SCD group had high sensitivity in differentiating this group from controls (0.94%). CONCLUSION: Our data suggest that despite normal performance in neuropsychological tests, the SCD elderly may face significant degrees of attention processing problems, especially in maintaining alerting to external stimuli which might be helpful in diagnosing individuals at risk and designing proper attention-based interventions.

Executive function deficits in mild cognitive impairment: evidence from saccade tasks.

OBJECTIVES: Early detection of mild cognitive impairment (MCI) is necessary to prevent irreversible brain damage caused by incipient Alzheimer's disease. It has been showing that amnestic MCI (a-MCI) subjects exhibit subtle deficits in executive function that can be tested using saccade eye movements. Eye-tracking technology is a sensitive method to measure cognitive impairments in dementia and MCI. METHODS: In this study, we used eye-tracking technology to explore saccade impairments to distinguish between a-MCI and the variants of reference controls. 21 patients with AD, 40 patients with a-MCI, and 59 normal participants were recruited in current study. We measured saccade reaction time, saccade errors, saccade omission, and uncorrected saccades using anti-saccade and pro-saccade tasks with 'gap' and 'overlap' procedures. These parameters were used as markers of executive function and visual attention deficits.Results: The findings revealed that more errors, more omissions, and fewer corrections characterized the saccade behavior of the a-MCI group compared to the reference group. These eye-tracking characteristics can be considered as inhibitory control and working memory deficits in a-MCI subjects. Our results thus demonstrate the applicability of the anti-saccade task as a cognitive marker in a-MCI. CONCLUSION: The work provides further support for eye-tracking as a useful diagnostic biomarker in the assessment of executive function in aging with cognitive impairments.

Prevalence and Determinant Factors of Diabetes Distress in Community-Dwelling Elderly in Qom, Iran.

BACKGROUND: Diabetes distress (DD) is common among the patients with type 2 diabetes (T2D), but few studies investigated this problem and its related factors in the elderly population. This study has focused on the prevalence rate of DD and its determinants in community-dwelling elderly in Qom, Iran. METHODS: This study was cross-sectional. A total of 519 subjects community-dwelling with T2D participated in the study. Collected data contained sociodemographic information, some clinical variables (body mass index and duration of diabetes) knowledge, attitude, and self-efficacy. Participants' distress was measured via diabetes distress scale (DDS). The cut of 3 (≥3) was considered as the presence of distress. Also, the attitude, self-efficacy, and knowledge about diabetes were measured by questioner. Multiple logistic regression analysis was applied to detect predictors of DD. RESULTS: The mean age of the participants was 68.38 ± 6.78 and 53.6% were female. Among the participants, 48.6% were identified with positive DD. According to the results of logistic regression analysis, being female (odds ration [OR] = 1.688, P = 0.009), being widowed or divorced (OR = 1.629, P = 0.027), being over-weight or obese (OR = 1.627, P = 0.027), and having less than 10 years in disease duration (OR = 1.721, P = 0.029), attitude (OR = 0.590, P < 0.001), and self-efficacy (OR = 0.658, P = 0.009) were identified as the independent predictors of DD. No significant association was found between DD and age, occupational status, education level, and knowledge (P > 0.05). CONCLUSIONS: The prevalence of DD is considerable among the elderly in Qom. It seems that more attention should be paid to the mental aspects of the patients with T2D specially in high risk groups.

Psychometric properties of the Short Form-8 Health Survey (SF-8) among diabetes and non-diabetes Iranian older people.

Background: The current study aimed to evaluate the psychometric properties of the Persian version of the 8-item Short-Form Health Survey (SF-8). For this purpose, we examined a large sample of the older adult in two different groups with and without diabetes using the YazdHealth Study (YaHS) data. Methods: Using a two-stage cluster random sampling method, 1901 older adults were recruited, according to the World Health Organization (WHO) STEPwise approach to surveillance(STEPS) guidelines. To test the scale's reliability, the internal consistency and test-retest methods were applied. The convergent validity of the entire questionnaire was evaluated by the average variance extracted (AVE) and composite reliability (CR) for each subscale. An independent samples t-test was used to assess the demographic differences between the study groups. Results: The Cronbach's alpha coefficient for the subscales of SF-8 were measured to range between 0.85 and 0.79 (physical & mental health). The test-retest reliability coefficient of the physical component summary (PCS) and (0.97) and mental component summary (MCS) (0.98)indicated the appropriate reliability of the SF-8. The CFA-concerned results indicated that the the2-factor model presented a good fit to the data for the explored diabetes and non-diabetes groups, as well as the total research participants [goodness of fit index (GFI)=0.99, comparative fit index (CFI)=0.992, normed fit index (NFI)=0.99, incremental fit index (IFI)=0.992, root mean square error of approximation (RMSEA)=0.056]. Values >0.5 and >0.7 for AVE and CR indicated the evidence of the convergent validity of the SF-8. Conclusion: The present study was the first attempt to confirm the traditional 2-factor structure of SF-8 among a large sample of Iranian older individuals. The obtained results suggested that the Persian version of the SF-8 is a reliable and valid tool for measuring health-related quality of life (HRQoL) among Iranian older adults (including the older adult with & without diabetes).

How do Iranian older adults define place attachment? a qualitative study.

Background: Place attachment is the emotional bond between individuals and environment, which seems to increase wellbeing in old age. The purpose of this study was to explore the concept of place attachment from older adults' perspective. Methods: In this qualitative study, a total of 14 older adults were purposively included in Aran and Bidgool city, Isfahan, Iran. The data were collected using a semi-structured interview and analyzed applying a directed content analysis approach. Results: As participants reported, place attachment meant intensive love, pride, dependency, and familiarity with the environment. Socio-economic attachment was identified as the most prevalent dimension of place attachment, followed by affective, physical, autobiographical, and religious-cultural attachment. Conclusion: Our findings provided a new understanding of place attachment in the context of Iran. The concept of place attachment was identified with a multidimensional nature from Iranian older adults' perspective. Such a multidimensionality of place attachment should be considered while planning for age-friendly cities or the operationalization of the subject of aging in place, particularly in the developing societies, like Iran.

Psychometric properties of modified MOS social support survey 5-item (MSSS-5-item) among Iranian older adults.

BACKGROUND: Social support is a key factor in public health. Since the precise evaluation of it is critical, the current study has been developed to evaluate the psychometric properties of the MOS-SSS questionnaire's abbreviated form (MSSS-5-item) among the Iranian older adults. METHODS: This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The questionnaire was first translated into Persian through the Forward & Backward method based on WHO guidelines. Next, the validity of scales was investigated by calculating face validity, content validity, Known-group validity, explanatory factor analysis, and confirmatory factor analysis indices. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability. Moreover, the scalability of the questionnaire was checked through the Mokken scale analysis. The software packages SPSS version 22, AMOS version 22, and R (Mokken package) were employed to analyze the data. RESULTS: the face validity was conducted using interviews with older adults and gathering the specialists' opinions. Then, the items were grammatically and lexically corrected accordingly. The CVI index of the overall scale was 0.94, and for every single item above 0.89. The results of the independent t-test showed that the current questionnaire well distinguished between the older adults who do and do not feel lonely (p < 0.001). Two components were recognized according to the explanatory factor analysis. They together explained 67.78% of the total variance of the questionnaire. The CFA showed that the two-factor model had acceptable fit indices. The questionnaire had desirable internal consistency (α = 0.78), stability (ICC = 0.98), and absolute reliability (SEM = 0.56, MDC = 1.57). Furthermore, the Mokken scale proved that MSSS-5-item was a strong scale (H = 0.51, se = 0.03). CONCLUSION: The present study results showed that the MSSS-5-item questionnaire had suitable validity and reliability to be used among Iranian older adults.
