This article analyzes the psychometric properties of the scale used in the research
corresponding to the topic “Stories of Abandonment. A Biographical-Narrative
Approach to the Academic Dropout in Andalusian Universities. Multicausal
Analysis and Proposals for Prevention.” The scale is composed of 71 items, with
five Likert-type response alternatives. The participants forming the convenience
sample were 970 from six Spanish universities. The study dimensions are: A.-
Motivation, B.-Commitment, C.-Attitude and behavior, D.-Socioeconomic
conditions, and finally E.-Permanence. The study begins by calculating the
statistical power and the effect size, thus determining the type I and type II error.
Similarly, reliability has been calculated based on the intercorrelation of items
through Cronbach’s alpha (0.906). The construct validity was carried out through
exploratory factor analysis, for which the correlation matrix was studied using
the Kaiser-Meyer-Olkin measure of sampling adequacy (KMO coefficient), in this
case the value is 0.886, the result of Bartlett’s test of sphericity is 0.000 and
the Determinant 4.009E−12, so we continue with the analysis of the correlational
structure, extracting the factors through the principal components method
and determining in this way the communalities with the highest and lowest
values. Next, we calculated the total variance explained, obtaining 16 factors
and an accumulated variance of 57.315%. Finally, the model was determined
by distributing the items according to the highest level of saturation by factors,
obtaining a 30-item scale with a Cronbach’s alpha of 0.893, which is reliable.
In conclusion, the questionnaire used complies with the psychometric aspects
necessary to be an optimal scale
