Introduction This study translated and validated the Urdu version of the European Organization for Research and Treatment of Cancer Quality of Life (QoL) Questionnaire (EORTC QLQ-C30) and Brain Module (QLQ-BN20) amongst patients with primary brain tumors (PBT) in Pakistan, and assessed the correlation of QoL with resilience, depression, and anxiety. Methods Translation of the EORTC QLQ-C30 and QLQ-BN20 was performed as per EORTC guidelines. A survey comprising of Urdu translations of EORTC QLQ-C30, QLQ-BN20, Wagnild and Young Resilience Scale (RS-14) and Hospital Anxiety and Depression Scale was administered to patients with PBT at a tertiary care hospital in Pakistan. Reliability (via Cronbach alpha), content validity index (CVI) scores, construct validity, and inter-scale correlations were assessed. Results Our sample consisted of 250 patients with PBT, most commonly glioma (46.8%) and meningioma (21.2%). All patients were able to understand the Urdu translations. The Cronbach alphas for the QLQ-C30 and the QLQ-BN20 were 0.860 and 0.880, respectively. The CVI scores for clarity and relevance were high for both the EORTC QLQ-C30 (0.98 and 0.96, respectively) and the QLQ-BN20 tool (0.81 and 0.95, respectively). The global QoL domain (EORTC QLQ-C30) showed significant positive correlations with resilience (r = 0.422), and significant negative correlations with depression (r = − 0.541) and anxiety (r = − 0.502). Strong inter-scale correlations were observed between physical functioning and insomnia (r = − 0.690) and role functioning and insomnia (r = − 0.641). Conclusion Our study confirms the Urdu versions of the EORTC QLQ-C30 and QLQ-BN20 as valid clinical tools for the measurement of QoL in primary brain tumors patients within the cultural and socioeconomic context of Pakistan.

“…This issue should be clarified in future studies. Finally, in order to facilitate the clinical application of this questionnaire, the minimum clinical important difference of the instrument should perhaps be further evaluated [44].…”

Background Self-efficacy is a significant predictor of return to work and affects the confidence of survivors to return to work after illness. The Return-to-work self-efficacy (RTW-SE) questionnaire is a self-report questionnaire to assess confidence in returning to work with good reliability and validity. The aim of this study was to translate and cross-culturally adapt the RTW-SE questionnaire into Chinese and examine the psychometric properties among young and middle-aged stroke survivors using Rasch model analysis. Methods The cross-cultural adaptation and translation procedures followed a dual-translation approach. The psychometric properties of the RTW-SE questionnaire were examined using Rasch model analysis by Winsteps software. The unidimensionality and local independence were analyzed by principal component analysis of the residuals (PCAR) and standardized residual correlations.Category diagnostics were performed for scale function, and the item fit, reliability, and separation were also validated. Item-person maps were used to examine the distribution and matching of item’s location and person ability. Finally, the differential item functioning (DIF) was used to measure gender-related group equivalence. Results A total of 366 participants aged 23–59 years were recruited from three communities in Zhengzhou. The RTW-SE questionnaire demonstrated unidimensionality and a 5-point Likert rating scale was more appropriate to investigate young and middle-aged stroke survivors’self-efficacy. There was a good fit for the items with both person and item reliabilities greater than 0.8 and separation indices of 3.75 and 3.94, respectively. The item location was identified from the item-person map as not covering person ability, but the scale did not have an age-related DIF. Conclusions The results confirm evidence of appropriate psychometric properties of the RTW-SE questionnaire and can be used as a reliable and validated instrument for measuring self-efficacy to return to work in young and middle-aged Chinese patients with stroke.

Objective Resilience instruments specific to family caregivers (FCs) in cancer are limited. This study was designed to validate the 10-item Resilience Scale Specific to Cancer (RS-SC-10) in FCs using multidimensional item response theory (MIRT) analysis. Methods 382 FCs were enrolled from Be Resilient to Cancer Program (BRCP) and administered with RS-SC-10 and 36-item Short Form Health Survey (SF-36). MIRT was performed to evaluate item parameters while Generalized Additive Model (GAM) and Latent Profile Analysis (LPA) were performed to test the non-linear relationship between resilience (RS-SC-10) and Quality of Life (QoL, SF-36). Results RS-SC-10 retained 10 items with high multidimensional discrimination, monotonous thresholds and its original two-factor structure (Generic and Shift-Persist). Four latent resilience subgroups were identified and a non-linear dose–response pattern between resilience and QoL was confirmed (per-SD increase OR = 1.62, 95% CI 1.16–2.13, p = 0.0019). Conclusion RS-SC-10 is a brief and suitable resilience instrument for FCs in cancer. The resilience screening of patients and FCs can be performed simultaneously in clinical practice.
