<p>Results summary for hypothesized mediation paths.</p>

Faculty support plays a vital role in shaping academic satisfaction among university students. However, its indirect effects through behavioural and psychological pathways such as sleep problems and smartphone addiction, have received limited research attention, particularly in resource-limited contexts like Ghana. This study modelled the association between perceived faculty support and academic satisfaction among student nurses, with sleep problems and smartphone addiction examined as mediating variables. A cross-sectional survey was conducted among 563 nursing students at the University of Cape Coast, Ghana. Standardised tools were used to assess perceived faculty support, sleep problems, smartphone addiction, and academic satisfaction. Data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). Faculty support was positively associated with academic satisfaction (r = 0.334, p < 0.001) and negatively associated with sleep problems (r = –0.727, p < 0.001) and smartphone addiction (r = –0.491, p < 0.001). Both sleep problems and smartphone addiction were significant negative predictors of academic satisfaction. Mediation analysis showed that both variables partially mediated the relationship between faculty support and academic satisfaction. Faculty support enhances academic satisfaction not only directly but also indirectly by reducing sleep-related issues and smartphone dependency. Strengthening faculty-student relationships could serve as a strategic intervention to improve academic well-being and behavioural regulation in nursing education, particularly within low-resource settings.

教职员工支持（Faculty Support）对大学生的学业满意度塑造至关重要。然而，其通过睡眠问题、智能手机成瘾等行为与心理路径产生的间接效应，却尚未得到足够的研究关注，在加纳这类资源受限地区尤为如此。本研究以护理专业学生为对象，构建了感知教职员工支持（Perceived Faculty Support）与学业满意度之间的关联模型，并将睡眠问题与智能手机成瘾作为中介变量展开分析。研究团队于加纳海岸角大学（University of Cape Coast）面向563名护理专业学生开展了横断面调查，采用标准化量表对感知教职员工支持、睡眠问题、智能手机成瘾及学业满意度进行评估。数据采用偏最小二乘结构方程模型（PLS-SEM）进行分析。结果显示，教职员工支持与学业满意度呈显著正相关（r=0.334，p<0.001），与睡眠问题（r=-0.727，p<0.001）及智能手机成瘾（r=-0.491，p<0.001）均呈显著负相关；睡眠问题与智能手机成瘾均为学业满意度的显著负向预测因子。中介效应分析结果表明，上述两个变量均在教职员工支持与学业满意度的关联中发挥部分中介作用。教职员工支持不仅可直接提升学生的学业满意度，还可通过缓解睡眠相关问题、降低智能手机依赖实现间接增益。强化师生关系可作为一项战略性干预措施，用于改善护理教育领域的学业福祉与行为调控，在资源匮乏地区尤为适用。
