Support Flexibility in Professional Online Communities: From Support-Seeking to Collective Resilience-Building During Sustained Societal Crisis

Professional online communities increasingly function as digital social infrastructures during societal disruption, yet less is known about how their support practices reorganize during prolonged crises. This study examined how social support, engagement patterns, and support-seeking behavior changed in a large Hebrew-language professional Facebook group for Israeli educators across routine and crisis periods. Quantitative content analysis was conducted on an analytic sample of 1008 posts published between January 2022 and July 2025, covering the pre-war period and the wartime period following October 2023. Posts were coded for informational, emotional, and instrumental support and for support-seeking, and negative binomial and logistic regression models examined engagement and predictors of support-seeking. Informational support was dominant (69.3%), followed by support-seeking (30.7%), emotional support (12.8%), and instrumental support (4.4%). During wartime, support-seeking and instrumental support were less frequent, whereas informational and emotional support were more frequent. Informational posts received approximately three times more likes, while support-seeking posts received fewer likes but sustained comment activity. Anonymous authors were more likely to seek support, but posts by anonymous authors received fewer comments. The findings suggest an aggregate pattern of support flexibility in the analytic sample, reflected in a relative shift from reactive support-seeking toward proactive informational sharing and emotional processing as part of collective resilience-building during sustained societal crisis.
