TY - JOUR PY - 2021// TI - Characteristics and unidimensionality of non-suicidal self-injury in a community sample of Spanish adolescents JO - Psicothema A1 - Pérez, Sandra A1 - Garcia-Alandete, Joaquín A1 - Gallego, Blanca A1 - Marco, José H. SP - 251 EP - 258 VL - 33 IS - 2 N2 - BACKGROUND: Few studies have explored the prevalence and unidimensional structure of Non-Suicidal Self-Injury (NSSI) in Spanish adolescents.

METHOD: in this study, we estimated the prevalence, types, and functions of NSSI in 1,733 Spanish adolescents, and we tested the unidimensional factorial structure of non-suicidal self-injury.

RESULTS: 24.6% of the adolescents referred to having self-injured at least once during their lifetime, and 12.7% had self-injured using more severe methods of NSSI. The most frequent types of NSSI were interfering with wounds (14.6%), scratching (12.5%), and hitting (11.7%). We found no differences between genders in NSSI frequency. The majority of the participants who self-injured referred to intrapersonal functions. The confirmatory factor analyses of the ISAS-I structure showed a single factor with 10 items, thus supporting the unidimensionality of the construct of NSSI.

CONCLUSIONS: NSSIs reflect difficulties in regulating emotions or managing interpersonal relationships in young Spanish people, and these behaviours seem to constitute a unique and latent dimension. Thus, there is a need for intervention programmes focused on managing problems of emotional regulation and maladaptive self-injury behaviours.
