Summary of the literature on knowledge sharing in smoking cessation OHCs

Authors	Research focus	Research method	Theory	Research findings
Ploderer et al. (2013)	Patterns of knowledge sharing	Content analysis	Social support theory	Users' sharing behaviors are distinctive to the stage of quitting. Specifically, most informational comments are made by users later in the process, while supportive responses and leadership are mainly from users who have just started it
Myneni et al. (2015)	Shared content	Mixed methods	–	Twelve themes were identified – namely social support, traditions, progress, cravings, motivation, benefits, virtual rewards, relapse, obstacles, nicotine replacement therapy, family and friends and conflict
Zhang and Yang (2015)	Patterns of knowledge sharing	Content analysis and social network analysis	Social support theory	Users who share information and knowledge often have been abstinent for a longer time than those who share emotional, esteem and network support
Myneni et al. (2016)	Shared content	Qualitative analysis	–	Forty-three concepts were identified. These were further grouped under 12 themes: conflict, virtual rewards, pharmacotherapy, family and friends, obstacles to quitting, benefits of quitting, readiness to quit, cravings, relapse, progress in quitting, social support and traditions
Cheung et al. (2017)	Shared content	Content analysis	Social support theory	The themes of sharing in smoking cessation OHCs were classified into three types: views and experience, encouragement and knowledge and information
Granado-Font et al. (2018)	Shared content	Content analysis	Social support theory	Most messages shared in smoking cessation OHCs provide informational and emotional support
Hefler et al. (2019)	Shared content	Experiment	–	Messages that are child-focused or feature indigenous content are most likely to be shared, and those that include disgusting images, are environment-focused or are ambiguous/sarcastic are less likely to be shared
Li et al. (2019)	Motivators for knowledge sharing	Conceptual paper (survey as the proposed method)	Privacy calculus theory	The authors posited that appraisals of threat (i.e. its perceived severity and vulnerability) negatively correlate with knowledge sharing while appraisals of coping (i.e. of response efficacy and self-efficacy) were proposed to have positive influences on knowledge sharing in smoking cessation OHCs
Li (2020)	Motivators for knowledge sharing	Questionnaire	Expectation confirmation theory	Knowledge sharing is positively influenced by satisfaction, which is determined by both perceived usefulness and confirmation
Li et al. (2021)	Motivators for knowledge sharing	Questionnaire	Post-acceptance model of IS continuance	The perceived usefulness of smoking cessation OHCs in general affects knowledge sharing in specific smoking cessation OHCs
