A Cross-Sectional Methodological Study to Validate Authentic Leadership Questionnaire (ALQ) Among Selected Latin American Nursing Staff.
Article in Journal of healthcare leadership, 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: Authentic leadership has been associated with work-related well-being, job satisfaction, and quality of nursing care. However, psychometric evidence supporting instruments used to assess this construct remains limited across Latin American nursing contexts, highlighting the need for further validation studies. Aim: To evaluate evidence of validity for the Methods: This cross-sectional methodological study included 418 nursing staff members-registered nurses and nursing assistants-selected through proportional stratified sampling from a public high-complexity hospital in Cali, Colombia, between May and October 2025. SELF and RATER versions of the ALQ were evaluated using confirmatory factor analysis. Four measurement models were compared for each version: unidimensional, correlated four-factor, second-order, and bifactor models. The final model was assessed through standardized loadings, internal consistency (McDonald's omega, ordinal alpha, composite reliability), measurement invariance (configural, metric, scalar) between nursing staff members, and correlations with job satisfaction. Results: The revised correlated four-factor model (excluding item 9) showed the best fit (ALQ-RATER: CFI= 0.998, TLI= 0.997, SRMR= 0.045, RMSEA= 0.079; ALQ-SELF: CFI= 0.996, TLI= 0.995, SRMR= 0.047, RMSEA= 0.050). Factor loadings were significant (RATER λ = 0.661-0.945; SELF λ = 0.671-0.897). Reliability was adequate (ALQ-RATER: ω = 0.883-0.938, ordinal α = 0.887-0.952, CR = 0.899-0.957; ALQ-SELF: ω = 0.801-0.847, ordinal α = 0.846-0.880, CR = 0.850-0.880). Configural, metric, and scalar invariance were supported. Registered nurses demonstrated significantly higher latent means across all authentic leadership dimensions than nursing assistants. All ALQ dimensions were positively associated with intrinsic job satisfaction (r = 0.287-0.550) and satisfaction with supervision (r = 0.336-0.633). Conclusion: The ALQ demonstrated evidence of structural validity, reliability, measurement invariance, and external validity among Colombian nursing staff. Implications for Health Management Services: The instrument can be used to assess authentic leadership in healthcare settings, support leadership development initiatives, and facilitate research examining its relationship with job satisfaction.
