A cross-sectional survey of 200 conventional farmers was conducted in Shibganj Upazila, Chapai Nawabganj district, northwest Bangladesh. Data were analyzed using partial least squares structural equation modeling (PLS-SEM) to test seven hypotheses linking HBM constructs—perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, cues to action, and general beliefs—to willingness to adopt organic-related practices. The model explained 95.8% of the variance in willingness ( R 2 = 0.958); this unusually high value likely reflects construct overlap and common-source measurement and should be interpreted with caution rather than as evidence of correspondingly strong explanatory power. In a re-specified robustness model (higher-order perceived threat; removal of semantically mirrored and ambiguous items), perceived threat ( β = 0.339, p = 0.013) and general beliefs ( β = 0.204, p = 0.009) were the only significant predictors, while perceived benefits attenuated to non-significance ( β = 0.216, p = 0.097), and discriminant validity remained unsatisfactory (HTMT ≥ 0.956); construct-specific estimates should therefore be read as exploratory. In the baseline model, perceived benefits showed the largest coefficient ( β = 0.608, p \u003C 0.001, f 2 = 0.277), followed by general beliefs ( β = 0.193, p = 0.011); cues to action were not significant ( β = 0.078, p = 0.155). Contrary to theoretical expectations, perceived susceptibility, perceived severity, perceived barriers, and self-efficacy showed no significant direct effects. HTMT ratios revealed potential construct overlap between threat and benefit perceptions (PB↔PSV = 1.069). Within the bounds of this purposive, single-district, predominantly male sample, the study suggests that a broadly positive but weakly differentiated orientation dominates stated willingness; the apparent primacy of benefit perception over threat appraisal was not robust to measurement re-specification, and it identifies boundary conditions for HBM effectiveness in agricultural settings. Findings tentatively suggest that interventions should prioritize benefit demonstration (e.g., demonstration plots, premium market linkages) over fear-based messaging. Structural barrier reduction—subsidized certification, organic input supply chains, transition-period crop insurance—is essential as high willingness coexists with high perceived barriers (M = 4.39–4.43).","本研究运用健康信念模型（Health Belief Model, HBM），识别孟加拉国小农户减少化学投入并采用有机相关耕作方式意愿的心理与认知决定因素。研究在孟加拉国西北部Chapai Nawabganj区Shibganj Upazila对200名常规农户进行了横断面调查。数据分析采用偏最小二乘结构方程模型（PLS-SEM），检验了七个将HBM构念——感知易感性、感知严重性、感知收益、感知障碍、自我效能、行动线索和一般信念——与采用有机相关实践意愿相联系的假设。该模型解释了意愿方差的95.8%（R² = 0.958）；这一异常高的数值可能反映了构念重叠和同源测量，应谨慎解读，而不应将其视为相应强解释力的证据。在重新设定的稳健性模型（高阶感知威胁；删除语义镜像和模糊题项）中，感知威胁（β = 0.339，p = 0.013）和一般信念（β = 0.204，p = 0.009）是唯一显著的预测因素，而感知收益减弱至不显著（β = 0.216，p = 0.097），区分效度仍不理想（HTMT ≥ 0.956）；因此，特定构念的估计值应被视为探索性的。在基线模型中，感知收益的系数最大（β = 0.608，p \u003C 0.001，f² = 0.277），其次是一般信念（β = 0.193，p = 0.011）；行动线索不显著（β = 0.078，p = 0.155）。与理论预期相反，感知易感性、感知严重性、感知障碍和自我效能均未显示出显著的直接效应。HTMT比率揭示了威胁感知与收益感知之间可能存在构念重叠（PB↔PSV = 1.069）。在这一目的性抽样、单区、以男性为主的样本范围内，研究表明，一种总体积极但分化较弱的取向主导了陈述性意愿；收益感知相对于威胁评估的表面优先性在测量重新设定后并不稳健，并识别出HBM在农业情境中有效性的边界条件。研究结果初步表明，干预措施应优先展示收益（如示范田、高端市场联结），而非采用恐惧导向的信息传递。结构性障碍的减少——su",null,"Frontiers in Sustainable Food Systems","2026-09-14T00:00:00Z","论文",10,false,67,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},8,20,16,13,1,"基于健康信念模型的小农户减施化学投入意愿实证研究，方法规范、数据翔实，但样本仅限孟加拉国单区200人，对国内三农实践参考价值有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"有机农业","化肥减量","农户行为","健康信念模型","孟加拉国",0,"10.3389\u002Ffsufs.2026.1868293",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":50,"direction":54,"ingested_from":56},"W7212452869",[36,38,40,42,44,46,48],{"name":37,"orcid":9},"A.
