Sleep Quality and Creative Self-Efficacy among College Students_ The Effect of Basic Psychological Needs and Stress.sav

Several studies have shown the complex relationship between sleep quality and creativity. Creative self-efficacy, as an individual's self-belief in completing creative tasks, is closely related to individual creative outcomes. This study aimed to explore the relationship between sleep quality and creative self-efficacy, primarily focused on the mediating effect of basic psychological needs and the moderating effect of stress. A sample of 264 college students from Northern China was involved in this study through the Creative Self-Efficacy Scale, Pittsburgh Sleep Quality Index, Basic Psychological Needs Scale, and Perceived Stress Scale. The results indicated that basic psychological needs had a suppression effect on the relation between sleep quality and creative self-efficacy, and stress played a moderating role in the mediation model. Specifically, the sleep quality of high-stress-sensing individuals had a significant negative direct effect on their creative self-efficacy. In contrast, the sleep quality of low-stress-sensing individuals had no significant direct effect on their creative self-efficacy. The results showed that basic psychological needs and stress played important roles in the influenced mechanism of sleep quality to creative self-efficacy and different strategies should be adopted in enhancing creative self-efficacy for individuals with different stress perceptions.

多项研究已证实睡眠质量与创造力之间存在复杂关联。创造自我效能感（Creative Self-Efficacy）作为个体对自身完成创造性任务能力的自我信念，与个体的创造性产出密切相关。本研究旨在探讨睡眠质量与创造自我效能感之间的关联，重点考察基本心理需求的中介效应与压力的调节效应。本研究招募华北地区264名大学生作为被试，采用创造自我效能量表（Creative Self-Efficacy Scale）、匹兹堡睡眠质量指数（Pittsburgh Sleep Quality Index）、基本心理需求量表（Basic Psychological Needs Scale）以及知觉压力量表（Perceived Stress Scale）开展数据采集。研究结果显示，基本心理需求对睡眠质量与创造自我效能感之间的关系存在遮掩效应，且压力在该中介模型中发挥调节作用。具体而言，高压力感知个体的睡眠质量对其创造自我效能感具有显著负向直接影响；与之相对，低压力感知个体的睡眠质量对其创造自我效能感则无显著直接影响。本研究结果表明，基本心理需求与压力在睡眠质量影响创造自我效能感的作用机制中扮演了重要角色，针对不同压力感知水平的个体，应采取差异化策略以提升其创造自我效能感。
