Objective: To predict suicidal ideation in people with schizophrenia, certain studies have measured its relationship with the variables of defeat and entrapment. The relationships are positive, but their interactions remain undefined. To further their understanding, this research sought to measure the relationship between suicidal ideation with the variables of loss, entrapment, and humiliation.
Method: The convenience sample included 30 patients with schizophrenia spectrum disorders. The study was prospective (3 measurement times) during a 6-month period. Results were analyzed by stepwise multiple regression.
Results: The contribution of the 3 variables to the variance of suicidal ideation was not significant at any of the 3 times (T1: 16.2%, P = 0.056; T2: 19.9%, P = 0.117; T3: 11.2%, P = 0.109). Further analyses measured the relationship between the variables of stigmatization, perceived cognitive dysfunction, symptoms, depression, self-esteem, reason to live, spirituality, social provision, and suicidal ideation. Stepwise multiple regression demonstrated that the contribution of the variables of stigmatization and perceived cognitive dysfunction to the variance of suicidal ideation was significant at all 3 times (T1: 41.7.5%, P = 0.000; T2: 35.2%, P = 0.001; T3: 21.5%, P = 0.012). Yet, over time, the individual contribution of the variables changed: T1, stigmatization (β = 0.518; P = 0.002); T2, stigmatization (β = 0.394; P = 0.025) and perceived cognitive dysfunction (β = 0.349; P = 0.046). Then, at T3, only perceived cognitive dysfunction contributed significantly to suicidal ideation (β = 0.438; P = 0.016).
Conclusion: The results highlight the importance of the contribution of the variables of perceived cognitive dysfunction and stigmatization in the onset of suicidal ideation in people with schizophrenia spectrum disorders.
Objectif:: Afin de prédire les idéations suicidaires des patients atteints de schizophrénie, quelques études ont mesuré leurs relations avec les variables échec-emprisonnement. Ces relations sont positives mais leurs interactions à préciser. Pour les expliciter, la recherche mesure leurs relations avec les variables perte-emprisonnement-humiliation.
Méthode:: L’échantillon de convenance comprend 30 patients avec des troubles du spectre schizophrénique. Prospective (trois temps de mesure), la recherche s’étale sur six mois. Les résultats sont analysés par une régression multiple stepwise.
Résultats:: la contribution des trois variables à la variance des idéations suicidaires n’est pas significative dans les trois temps (T1: 16.2%; p=.056); T2: 19.9%; p=.117); T3: 11.2%; p=.109). Des analyses complémentaires ont mesuré les relations entre les variables stigmatisation, troubles cognitifs, symptômes, dépression, estime de soi, raisons de vivre, spiritualité, provisions sociales et idéations suicidaires. Une régression multiple stepwise montre que la contribution des variables stigmatisation et troubles cognitifs à la variance des idéations suicidaires est significative aux trois temps (T1: 41.7.5% (p=.000); T: 35.2% (p=.001); T3: 21.5% (p=.012). Mais à travers le temps, la contribution individuelle des variables varie: T1, stigmatisation (β = .518; p = .002); T2, stigmatisation (.394; p = .025) et troubles cognitifs (β = .349 p = .046); T3, troubles cognitifs seulement (β = .438 p = .016).
Conclusion:: les résultats soulignent l’importance de la contribution des variables troubles cognitifs et stigmatisation à l’apparition des idéations suicidaires chez les troubles du spectre schizophrénique
