The Relationship between Self-Directed Learning and Problem-Solving Ability: The Mediating Role of Academic Self-Efficacy and Self-Regulated Learning among Nursing Students.

Problem-solving ability is necessary for the clinical reasoning and decision-making of nurses to solve patients' health problems. This study aims to investigate the association between self-directed learning and problem-solving ability using the multiple mediation model to identify strategies to enhance problem-solving ability in nursing students. This is a descriptive survey study of 193 nursing students from two universities in South Korea. Data about self-directed learning, self-regulated learning, academic self-efficacy, and problem-solving ability were collected using structured questionnaires between 5 March and 17 June 2018, and were analyzed using serial multiple mediation analysis. The direct effect of self-directed learning on problem-solving ability was statistically significant. The serial multiple mediation technique predicting problem-solving ability from self-directed learning, academic self-efficacy, and self-regulated learning was significant, explaining 40% of the variance in problem-solving ability. The relationship between self-directed learning and problem-solving ability was partially mediated by academic self-efficacy and self-regulated learning. This study suggests the suitability of considering academic self-efficacy and self-regulated learning together when conducting self-directed learning to improve nursing students' problem-solving ability.
