Background: In nurses, self-compassion mitigates the effects of stress, burnout and compassion fatigue, and enhances empathy, compassion and well-being and quality of life. The Self-Compassion Scale is the most-used instrument. The aim of this study is to validate the Spanish version of the new developed State Self-Compassion Scale–Long (SSCS–L). Methods: Students of the first year of the Nursing Degree were surveyed online. Together with the SSCS–L, their levels of positive and negative affect was reported. Analyses included descriptive statistics, competitive confirmatory factor analysis, evidence on criterion-related validity and estimates of reliability. Results: The best fitting model for the SSCS–L was the one hypothesizing six-correlated factors of self-compassion: self-kindness, common humanity, mindfulness, self-judgement, isolation, and over-identification. Positive relations between the positive dimensions of self-compassion and positive affect were found, whereas there were negative relations between the positive poles of self-compassion and negative affect. Estimates of reliability were adequate, except for the dimension of over-identification. Conclusions: Self-compassion has become a key competency for nurses. The SSCS–L is an appropriate tool to allow an adequate assessment of self-compassion in experimental contexts.
