Social Identity and Organisational Citizenship Behaviour: Key Predictors of Critical Care Nursing Practice.
Article in Nursing in critical care, 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
backgroundOrganisational Citizenship Behaviour (OCB) and Social Group Membership (SGM) are critical for enhancing organisational effectiveness and nurse well-being. While SGM's role in fostering OCB is acknowledged globally, its bidirectional relationship remains underexplored in nursing contexts.
aimTo identify predictors of SGM and OCB among critical care nurses and examine their reciprocal relationship. STUDY
designA cross sectional, correlational study was conducted. Validated tools, the Multiple Group Membership (MGM) Scale and Organizational Citizenship Behavior Scale (OCBS) were used. Data were analysed via Pearson correlation and multiple linear regression.
resultsAmong 163 critical care nurses were included, significantly predicted OCB (β = 0.643, p < 0.001), explaining 78.2% of its variance. Work-related factors, including nursing experience (β = 0.503), weekly workload (β = 0.350) and night shifts (β = 0.482), also predicted OCB. Conversely, OCB predicted SGM (β = 0.643, p < 0.001), with 47.2% variance explained. Age, experience and night shifts further influenced SGM. A bidirectional relationship between SGM and OCB was confirmed, moderated by organisational demands and support structures.
conclusionsEnhancing nurses' engagement in professional and social networks fosters a reinforcing cycle of prosocial behaviour and social connectivity. Hospital administrators should prioritise SGM-promoting strategies, such as mentorship and professional associations, to improve OCB, job satisfaction and patient care outcomes. RELEVANCE TO CLINICAL PRACTICE: This study is relevant to critical care practice as it highlights how social identity and OCB influence teamwork, collaboration and voluntary supportive actions among nurses. Strong professional identification enhances cooperation, reduces conflict and improves communication, leading to better coordination, efficiency and ultimately higher quality patient care in critical settings.
