Development and preliminary validation of the post-intensive care syndrome-family assessment scale.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Post-Intensive Care Syndrome-Family (PICS-F) is a condition that often develops in family caregivers of ICU patients and severely impacts their quality of life. Currently, there is a lack of comprehensive assessment tools suitable for the Chinese cultural context. Objective: To develop and validate a culturally appropriate scale for assessing PICS-F in family members of ICU patients within the Chinese context. Methods: This study adopted an exploratory sequential mixed-methods design. The scale was developed based on a preliminary qualitative study and guided by the Theory of being devastated by the critical illness journey in the family. An initial pool of 42 items was generated. Content validity was evaluated through expert consultation. A pilot survey was conducted. A cross-sectional survey was then performed with 447 family members. Reliability and validity were assessed using item analysis, exploratory factor analysis, confirmatory factor analysis, and Cronbach's Results: Content validity indices were adequate (item-level content validity index (I-CVI): 0.80-1.00; scale-level content validity index/average (S-CVI/Ave) = 0.98). The final PICS-F Assessment Scale contains 19 items across three dimensions: Psychological Trauma and Distress (8 items), Social and Family Functioning Impairment (8 items), and Deteriorating Physical Health (3 items). Exploratory Factor Analysis (EFA) supported the three-factor structure, accounting for 56.98% of the total variance. Confirmatory Factor Analysis (CFA) indicated adequate model fit [ Implications for clinical practice: The scale provides a practical tool for early screening and assessment of PICS-F in clinical settings, facilitating timely and targeted support for at-risk family caregivers. Conclusion: The PICS-F Assessment Scale demonstrated promising preliminary psychometric properties for holistically assessing the impact of critical illness on family members, demonstrating good internal consistency reliability, content validity, and construct validity. Further validation with larger samples and criterion-related measures is needed.
