Abstract
Background: Because of the numerous problems created by neurofibromatosis type 1, particular quality-of-life evaluation measures are quite significant. In Iran, general instruments are used to assess the quality of life of the target group. This study aimed to translate and examine the psychometrics of the Persian version of the Neurofibromatosis Type 1 Adult Health-related Quality of Life (NF1-AdQOL) questionnaire.
Methods: This was a methodological and cross-sectional study. A total of 414 adult patients with neurofibromatosis type 1 in the Iranian Association of Neurofibromatosis were selected via convenience sampling. With the permission of the questionnaire's developer, the English version was translated into Persian using the standard back-translation procedure. Validity was assessed using face validity, content validity, exploratory, and confirmatory factor analysis. The reliability and internal consistency of the questionnaire were assessed by Cronbach's alpha and Spearman's correlation, respectively.
Results: The participants' mean age was 34.48±8.3 years. The 31-item questionnaire was translated into Persian, and based on content validity analysis, 2 items were removed. The adequacy of the sample size was acceptable (KMO = 0.940). Exploratory factor analysis revealed 4 factors. The scale had good reliability (Cronbach's alpha: 0.95), and the intraclass coefficient was 0.91. The total mean quality of life score was 93±25.18.
Conclusions: The finding showed that the Persian version of the questionnaire has good structural characteristics and is a reliable and valid instrument for measuring the quality of life of patients with neurofibromatosis 1.

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

Abstract
Background: Some men use a nuanced set of attitudes, behaviors, and beliefs referred to as “invisible violence” to exert control over women. Although these behaviors are culturally accepted, they remain risk factors for intimate partner violence. Early detection of invisible violence can prevent domestic violence and its negative consequences. Therefore, this study aimed to evaluate the psychometric properties of the Persian version of the Questionnaire for the Invisible Violence Against Women (Q-IVAW).
Methods: This cross-sectional study was conducted on 520 married women who were referred to health centers in Western Iran (Asadabad) in 2023. Sampling was performed using a convenience sampling method. After forward-backward translation, face, content, and construct validity (through exploratory and confirmatory factor analysis) were conducted. Internal consistency was assessed using Cronbach's alpha and McDonald's omega coefficients and stability was assessed using a test-retest. The data were analyzed using SPSS version 16 and Amos version 26 software.
Results: In the exploratory factor analysis, four factors, including ‘utilitarian-benevolent sexist behaviors’, ‘crisis sexist behaviors’, ‘coercive sexist behaviors’, and ‘ambivalent sexist behaviors’, were extracted using the maximum likelihood method and Promax rotation. Cronbach's alpha for the four factors was 0.803, 0.724, 0.733, and 0.704, respectively. These factors account for 47.17% of the total variance. In confirmatory factor analysis, the final model demonstrated a good fit (CMIN/DF = 2.140, GFI = 0.952, AGFI = 0.932, NFI = 0.924, IFI = 0.958, CFI = 0.958, RMSEA = 0.047).
Conclusion: The Persian version of the Q-IVAW has acceptable psychometric properties and can be used to measure invisible violence in Iranian women.

Abstract
Background: Declining fertility and childbearing are significant public health concerns. The Multi-Theory Model (MTM), which addresses both the initiation and maintenance of behavior, may provide a useful framework for promoting childbearing intentions. However, no validated theory-based instrument currently exists to measure MTM constructs in this context. Therefore, this study aimed to develop and validate a Persian questionnaire based on MTM to assess childbearing intentions among women of reproductive age.
Methods: A cross-sectional descriptive survey was conducted in 2025 with 275 married women recruited from comprehensive health centers in Yazd, Iran. Women with only one child and willing to participate from the selected health centers were included in this study. An initial 37-item researcher-developed instrument based on MTM was refined through expert evaluation (CVR, CVI) and quantitative face validity (Impact score). Construct validity was assessed via confirmatory factor analysis (CFA), and reliability evaluated using via Cronbach’s alpha and test–retest ICC analyzed with SPSS 22 and AMOS21.
Results: During the psychometric validation process, four items were removed. The final questionnaire with 33-items demonstrated high reliability (Cronbach’s α = 0.93; construct-level α = 0.71-0.92; test-retest ICC =0.81 (95% CI: 0.68-0.90)) and acceptable construct validity (CFA: CFI =0.932, TLI =0.921, RMSEA = 0.06, χ²/df =1.97). Content validity was strong, with CVR ranging from 0.62-1, S-CVI/Ave =0.929, and overall CVI =0.91. All items also showed acceptable face validity (Impact score >1.5).
Conclusion: The validated MTM-based Persian childbearing intention questionnaire is a reliable and valid tool for assessing childbearing intentions among women with only one child. It can guide public health research, educational interventions, and policy planning to support informed reproductive decisions.
