The outcome measure was endorsement of suicide attempt with some intent to die. General model structure was: Outcome ~ Age + Sex + Predictor₁… Predictor_N. Age and sex each appearing before the predictors of interest yielded predictor estimates that controlled for age and sex
SCS-R Spanish version of suicide cognitions scale-revised; PHQ-A patient health questionnaire-adolescent version; UP3 the unbearable psychache scale. Entrapment. E-SF entrapment scale short-form
