Self-Perceived Competence and General Happiness Scores Among Acute-Care Nurses in the United Arab Emirates: A Cross-Sectional Study.
Article in Nursing open, 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
aimTo examine the association between scores on an investigator-adapted self-perceived nursing competence questionnaire and a five-point modification of the Oxford Happiness Questionnaire among registered nurses in one acute-care hospital in the United Arab Emirates.
designCross-sectional correlational survey.
methodsBetween 15 September and 15 November 2025, 200 direct-care registered nurses completed an online survey. Self-perceived competence was scored with a 21-item investigator-adapted questionnaire informed by Nurse Competence Scale domains; general happiness was scored with a 29-item Oxford Happiness Questionnaire modified to use five response categories. Neither modified score is established as psychometrically equivalent to its source instrument. Exploratory factor analysis, correlation and covariate-adjusted linear regression with HC3 robust inference were used.
resultsThe adapted scores correlated modestly (r = 0.293, 95% CI 0.160-0.414); the adjusted competence-score coefficient was B = 0.440 (95% CI 0.248-0.633). Removing a competence item about feeling valued and supported within the team yielded r = 0.290 and adjusted B = 0.447 (95% CI 0.248-0.645). Exploratory factor analyses indicated factorability but did not validate either adaptation: the competence items did not reproduce seven intended domains, and happiness items primarily separated by wording polarity.
conclusionHigher scores on the locally adapted self-perceived competence questionnaire were associated with higher scores on the modified general happiness questionnaire. The modest, cross-sectional, concurrent self-report association does not establish construct equivalence, direction of effect or benefits from competence training. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Support for professional capability may be considered as one component of a broader workforce strategy that addresses staffing, workload, leadership, recognition and psychological safety. IMPACT: Earlier research examined competence and happiness among nurses in Iran; this study extends the question to a contemporary multicultural UAE acute-care sample. Its modest association between adapted questionnaire scores is useful for hypothesis generation, subject to measurement and sampling limitations. REPORTING
methodThe study is reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology checklist for cross-sectional studies. PATIENT OR PUBLIC CONTRIBUTION: No patients or members of the public contributed because this study examined registered nurses as professional participants; nurses contributed only as survey respondents.
