Toward Understanding of Suicidality in a Spanish Clinical Population: Validation of the European Spanish Version of the Interpersonal Needs Questionnaire.

INTRODUCTION: Suicidal ideation (SI) represents one of the most prominent predictors of suicidal behavior (SB). The Interpersonal Needs Questionnaire (INQ) was developed from the Interpersonal Theory of Suicide (ITS) to assess the 2 core drivers of SI proposed by the theory. Despite the relevance of suicide-related ideations and ITS, there is a lack of psychometric measures validated in clinical Spanish population that adequately evaluate SI components of ITS. Thus, the main aim of the study was to validate INQ-10 in a Spanish clinical sample including the genuine cultural and linguistic characteristics of European Spanish. METHODS: 315 participants were included in the analyses; 149 of them consulted mental health services for the presence of suicide-related behaviors. A series of exploratory and confirmatory factor analyses were carried out to identify the factor solution. Bivariate and multivariate analyses were used to analyze psychometric properties. Finally, sensitivity and specificity properties were explored through receiver-operating characteristic analyses which also provided the cut-off values of the questionnaire. RESULTS: An 8-item version demonstrated a good fit to the 2-factor solution. Likewise, this 8-item version showed good psychometric properties. Sensitivity and specificity indices of the version validated as well as the calculated cut-off points were excellent. CONCLUSIONS: The current results demonstrate the utility of an 8-item INQ European Spanish version as a valid measure of the current SI in Spanish clinical population. In addition, the validated form reflects the theoretical framework on which it was built.

One-year follow-up study of first suicide attempts in first episode psychosis: Personality traits and temporal pattern.

OBJECTIVES: The highest suicide rates occur after psychiatric hospitalization or soon after discharge. In addition to other factors, personality traits have been suggested as predictors of suicide attempts (SA) after first episode psychosis (FEP). In this study we examined their temporal pattern and the influence of personality traits on first suicide attempts (fSA) during one year after FEP. METHOD: One-year follow-up of 65 FEP patients. Bivariate and multivariable analyses were performed to explore the relationship between personality traits and fSA. This analysis was also adjusted for a set of sociodemographic, clinical and psychopathological variables. RESULTS: fSAs in the six months following FEP were predicted by higher scores in passive-dependent personality traits (OR = 2.42, 95% CI = 1.15-5.09) and severity of symptoms at onset (OR = 2.00, 95% CI = 1.07-3.76). Severity of symptoms at onset (OR = 2.71, CI = 1.15-6.39) was the most significant predictor of fSA from six to twelve months after FEP. Seventy percent of fSA occurred during the first six months after FEP, decreasing considerably afterwards. CONCLUSIONS: Our study suggests that personality traits play a role in fSA after FEP. Specifically, passive-dependent personality traits emerged as a predictor of fSA in the six months following FEP. Severity of symptoms at onset predicted early and late first suicide attempts. We also found that risk of fSA is highest during the six months following FEP. These results can contribute to the implementation of prevention program.

Suicidal Behavior and Personality Traits Contribute to Disability in First-episode Psychosis: A 1-Year Follow-up Study.

BACKGROUND: Disability encompasses impairments, activity limitations, and restrictions on participation. Improvement in functioning has therefore become a crucial outcome of treatment in psychosis. OBJECTIVE: The main aim of this study was to analyze the potential relationship between suicidal behavior after first episode of psychosis (FEP) and family disability. The second aim was to find out whether personality traits are associated with disability dimensions. METHOD: The study sample was composed of 65 FEP patients. The personal care, occupational, family, and social dimensions of disability were evaluated at 12 months after FEP. Bivariate and multivariate analyses were performed to explore any putative outcome factors associated with dimensions of disability. RESULTS: Personal care during the 1-year follow-up was significantly impaired in suicide attempters and significantly associated with sociopathic personality traits. A decline in occupational functioning was significantly associated with schizotypy traits. On the other hand, deterioration in family, social, and global functioning at 1 year after FEP was related to poor premorbid adjustment during late adolescence. CONCLUSIONS: Suicidal behavior prevention could improve psychosocial functioning, particularly personal care, in FEP. In addition, sociopathic and schizotypy personality traits as well as poor premorbid adjustment during late adolescence appear to be useful early markers of future disability.
