<p>The purpose of this study was to evaluate an explanatory model of risk for suicidal ideation, which involved the dimensions of parental socialization and perceived family functionality, as well as to establish the influence of the style of socialization of fathers and mothers. The ESPA-29, the APGAR and the BECK-HF Suicidal Ideation Scale were applied to a sample of 268 adolescents. The model of best indicators of goodness of fit (ꭓ2 = 22.2, p = .022, CMINDF = 2.023, CFI = .968, TLI = .919, NFI = .942, RMSEA = .061) establishes an influence of acceptance/involvement of both parents on family functioning, which reduces the level of suicidal ideation; the age and the coercion/imposition of the father also have a direct impact. The results are compared with the scientific literature and courses for research are established.</p>
