The extant literature on the bias effects of helpful reviews mainly concentrates on traditional e-commerce, whereas research on OHCs is still rare. Thus, based on the heuristic-systematic model (HSM), this research explores how two unique reviewer characteristics in OHCs, which may induce attribution bias and confirmation bias, affect review helpfulness and how review length moderates these relationships.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>This research analyzed 130,279 reviews collected from haodf.com (one of the representative OHCs in China) by adopting the negative binomial regression to test our research model.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The results indicate that reviewer cured status positively influences review helpfulness, whereas reviewer recommendation source negatively affects review helpfulness. Moreover, the effects of the two reviewer cues on review helpfulness will be weaker for longer reviews.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>First, as one of the initial attempts, the current study investigates the effects of confirmation bias and attribution bias of online reviews in OHCs by exploring the effects of two unique reviewer characteristics on review helpfulness. Second, the weakening moderating effects of review length on the two bias effects provide empirical support for the theoretical arguments of the HSM in OHCs.<\/jats:p><\/jats:sec>","DOI":"10.1108\/oir-05-2021-0248","type":"journal-article","created":{"date-parts":[[2022,9,18]],"date-time":"2022-09-18T20:18:34Z","timestamp":1663532314000},"page":"680-696","source":"Crossref","is-referenced-by-count":10,"title":["Will reviewer recommendation source and cured status bias review helpfulness in online health community?"],"prefix":"10.1108","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3288-693X","authenticated-orcid":false,"given":"Yajie","family":"Hu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9267-0567","authenticated-orcid":false,"given":"Shasha","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"issue":"1","key":"key2023072606334017900_ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1086\/321944","article-title":"Sometimes it just feels right: the differential weighting of affect-consistent and affect-inconsistent product information","volume":"28","year":"2001","journal-title":"Journal of Consumer Research"},{"key":"key2023072606334017900_ref002","doi-asserted-by":"crossref","first-page":"113063","DOI":"10.1016\/j.dss.2019.05.003","article-title":"Behavioral economics for decision support systems researchers","volume":"122","year":"2019","journal-title":"Decision Support Systems"},{"issue":"2","key":"key2023072606334017900_ref003","first-page":"99","article-title":"Helpfulness of online consumer reviews: readers' objectives and review cues","volume":"17","year":"2014","journal-title":"International Journal of Electronic Commerce"},{"issue":"3","key":"key2023072606334017900_ref004","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1086\/209118","article-title":"Social ties and word-of-mouth referral behavior","volume":"14","year":"1987","journal-title":"Journal of Consumer Research"},{"issue":"5","key":"key2023072606334017900_ref005","doi-asserted-by":"crossref","first-page":"752","DOI":"10.1037\/0022-3514.39.5.752","article-title":"Heuristic versus systematic information processing and the use of source versus message cues in persuasion","volume":"39","year":"1980","journal-title":"Journal of Personality and Social Psychology"},{"key":"key2023072606334017900_ref006","first-page":"3","volume-title":"Social influence: The Ontario symposium","year":"1987"},{"issue":"3","key":"key2023072606334017900_ref007","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1037\/0022-3514.66.3.460","article-title":"Heuristic processing can bias systematic processing: effects of source credibility, argument ambiguity, and task importance on attitude judgment","volume":"66","year":"1994","journal-title":"Journal of Personality & Social Psychology"},{"issue":"16","key":"key2023072606334017900_ref011","doi-asserted-by":"crossref","first-page":"2679","DOI":"10.1080\/13683500.2021.1988523","article-title":"Does managerial response moderate the relationship between online review characteristics and review helpfulness?","volume":"25","year":"2022","journal-title":"Current Issues in Tourism"},{"issue":"4","key":"key2023072606334017900_ref008","doi-asserted-by":"crossref","first-page":"463","DOI":"10.1509\/jmr.12.0063","article-title":"Temporal contiguity and negativity bias in the impact of online word of mouth","volume":"50","year":"2013","journal-title":"Journal of Marketing Research"},{"key":"key2023072606334017900_ref009","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/j.dss.2018.12.008","article-title":"Why do participants continue to contribute?
