Difference in the relation between gender and suicidality was founded t (751): -6.69; p < 0,001, beinggreater in women. Age (r: 0.12; p < 0.01) and impulsivity (r: 0,28; p < 0.001) is related directly to suicidality; self-esteem (r: -0.49;p < 0.001), family cohesión (r: -0.36; p < 0.001) and social support (r: -0.34; p < 0.001) inversely. The predictors explains 33.8%) ofthe suicidality (R2:0.338); they contribute in sequence of impórtame: self-esteem (ß: -0.33; sr.2:0.08; p < 0.001), gender (ß: -0.19; sr.2:0.033; p < 0.001), impulsivity (ß: 0,17; sr.2: 0.025; p < 0.001), family cohesión (fc -0.14; sr.2: 0.011; p < 0.001), social support (ß: -0.11; sr.2: 0.008; p < 0.01) and age (ß: -0.07; sr.2: 0.005; p < 0.05).
