Background. The sense of coherence (SOC), the central concept of the salutogenesis model described by Aaron Antonovsky, has been employed as a predictor of measures of perceived and objective health. It is strongly and positively related to healthy behaviour and is mainly developed while young and studying. University students are a target youth group for applying measures promoting health according to their SOC level; it is therefore necessary to check the quality of the scale's measurement. The goal is to validate and study the psychometric properties of the SOC scale in students at the University of Navarre and determine their temporal evolution.
Methods. Newly enrolled students at the University of Navarre were analysed. Cohort study with a 3 year follow-up. The instruments used were the Orientation to Life Questionnaire (OLQ-13), Perceived Stress Scale (PSS) and the Discomfort Index. The following were studied: the quality and viability of the data, scale assumptions, temporal stability, reliability, concurrent and clinical validity, as well as factorial structure and confirmatory analysis of the data obtained. SPSS v. 19 and Amos v.7 statistical software were used.
Results. The study sample consisted of 508 students, 33.5% male and 65.9% female. High reliability (Cronbach Alpha 0.814). Adequate validity converging with the PSS. Inadequate clinical validity. Analysis of main components with three factors that explain 50.73% of the variation.
Conclusions. A valid instrument that makes it possible to propose it as a tool for applying measures promoting health in young people.
