García Martín, María Belén | 2019

The objective of the present investigation is to analyze the psychometric properties of the Spanish version of the Inventory of Statements About Self - Injury ISAS in a sample of 605 Colombian adolescents, aged between 13 and 17 years. A psychometric study of the ISAS Scale was carried out with 39 items and later a sychometric study with a reduced version of 30 items (ISAS). The items showed appropriate saturation values, showing relations with ranges for factor 1 between 0.409 (Item 9) and 0.932 (Item 34) and for factor 2, ranges between 0.455 (item 32) and 0.826 (item 19). The Barlett sphericity test (P <0.000010) was significant and the Kaiser Meyer Olkin (KMO) sample adequacy test (0.91586) indicated that the data are susceptible for exploratory factor analysis with a two-factor structure. It is concluded that the reduced version of ISAS (30 items) has adequate psychometric properties to measure self-harm in Colombian adolescents. Similarly, different applied instruments allowed correlations involving cognitive components with private events, stressful states and decreased mood, with anxiety behaviors related to the intrapersonal factor, emotional regulation associated with emotional intelligence levels, with the interpersonal factor.
