Publication Open Access Is psychological treatment equally effective for intimate partner violence perpetrators with and without childhood family violence?(Wiley, 2020) Fernández-Montalvo, Javier; Echauri, José Antonio; Siria Mendaza, Sandra; López-Goñi, José Javier; Azcárate, Juana M.; Martínez, María; Ciencias de la Salud; Osasun ZientziakObjetivo: Este estudio evaluó la eficacia diferencial a largo plazo de un programa de tratamiento para agresores de violencia hacia la pareja (IPV),) dependiendo de haber sufrido o no violencia familiar infantil (CFV). Método: Se incluyó una muestra de 1.008 agresores masculinos en el estudio. En la evaluación pretratamiento se realizaron comparaciones entre maltratadores con CFV (n= 339) y sin CFV (n= 669) sobre características sociodemográficas y variables psicopatológicas. La eficacia diferencial del tratamiento se evaluó en el post-tratamiento, y en el seguimiento a un año. Resultados: La evaluación previa al tratamiento mostró que los agresores con CFV tenían un nivel de educación más bajo, tasas más altas de antecedentes psiquiátricos previos y el acceso voluntario al tratamiento. Además, iniciaron el programa de tratamiento con más síntomas psicopatológicos, evaluados a través del SCL-90-R y el STAXI-2. En cuanto a los resultados del tratamiento, las tasas no alcanzaron diferencias significativas entre los grupos. Las medidas repetidas ANOVA evidenciaron una mejora estadísticamente significativa en los síntomas psicopatológicos en la mayoría de las variables para ambos grupos. Sin embargo, las comparaciones entre grupos sobre síntomas psicopatológicos mostraron que los agresores con CFV se vieron afectados en un grado significativamente mayor en muchas variables en el post-tratamiento y en el seguimiento, aunque no se encontraron diferencias en las tasas globales de resultados del tratamiento. Discusión: Esta investigación pone de relieve la heterogeneidad de los agresores masculinos de la IPV y la progresión diferencial a lo largo de los programas de tratamiento de acuerdo con la presencia de CFV.Publication Open Access What differentiates batterer men with and without histories of childhood family violence?(SAGE, 2020) Fernández-Montalvo, Javier; Echauri, José Antonio; Azcárate, Juana M.; Martínez, María; Siria Mendaza, Sandra; López-Goñi, José Javier; Ciencias de la Salud; Osasun ZientziakAims: The goals of this study were to explore the prevalence of childhood family violence (CFV) (both suffered and witnessed) among male batterers in treatment, and to analyse the specific psychological profile of these perpetrators with CFV. Method: A sample of 1421 men recruited from a specialized batterer treatment programme was assessed. A description of the sociodemographic, violence and psychopathological characteristics of the sample was carried out. Moreover, a comparison of all the variables studied between batterer men with and those without CFV was conducted. Findings: The results showed that 35.2% (n = 500) of the sample reported having been victims of CFV (67.2% of them directly suffered abuse, and 32.8% witnessed violence between their parents, mainly from father to mother). Batterers with CFV presented with more irrational beliefs both about women and about violence as a strategy to cope with everyday difficulties. Moreover, they had significantly higher scores than batterers without CFV on all psychopathological symptoms as assessed by the SCL-90-R, as well as on most of the STAXI-2 subscales. In the logistic regression analysis, the main variables related to having a history of CFV were low education level, voluntary access to the programme, having a previous psychiatric history, being an immigrant, having children, and presenting a greater number of psychopathological symptoms. Major implications: According to these results, batterers with CFV showed a higher severity in most of the variables studied than those without CFV. Consequently, these findings highlight the importance of tailoring batterer treatment programmes to their specific characteristics, particularly those regarding childhood victimization.Publication Open Access Differential MCMI-III psychopathological profiles between intimate partner violence perpetrators with and without childhood family violence(Wiley, 2021) Siria Mendaza, Sandra; Fernández-Montalvo, Javier; Echauri, José Antonio; Arteaga Olleta, Alfonso; Azcárate, Juana M.; Martínez, María; Ciencias de la Salud; Osasun ZientziakThis study explored the differential prevalence of personality disorders (PD) and clinical syndromes between male perpetrators of intimate partner violence (IPV) with and without a history of childhood family violence (CFV). A sample of 981 perpetrators of IPV was assessed with the Millon Clinical Multiaxial Inventory-III (MCMI-III). Comparisons of sociodemographic characteristics and MCMI-III scales' scores between perpetrators with (n = 293) and without (n = 688) CFV were carried out. Results showed that IPV perpetrators with CFV had a lower level of education, were less frequently employed, and had higher rates of previous psychiatric history than perpetrators without CFV. Statistically significant differences between groups in almost all the MCMI-III scales were found. Perpetrators with CFV presented with higher scores on most of the evaluated scales and showed a more severe psychopathological profile than perpetrators without CFV. The multivariate analysis showed that the main MCMI-III domains related to CFV were higher scores on the disclosure and alcohol dependence scales and lower scores on the passive-aggressive scale. These findings reveal that CFV is associated with a more severe psychopathological profile in perpetrators of IPV. In order to develop tailored interventions, the presence of CFV and psychopathological symptoms should be assessed in IPV perpetrators.Publication Open Access Treatment effectiveness for male intimate partner violence perpetrators depending on problematic alcohol use(Elsevier, 2022) Siria Mendaza, Sandra; Fernández-Montalvo, Javier; Echauri, José Antonio; Azkárate, Juana; Martínez, María; Olabarrieta Landa, Laiene; Rivera, Diego; Ciencias de la Salud; Osasun ZientziakBackground: Problematic alcohol use (PAU) is highly correlated with intimate partner violence perpetration (IPV). However, when treatments for male IPV perpetrators that address alcohol consumption are evaluated, the results are varied. Therefore, the main goal of this study was to assess the differential long-term effectiveness of a standard individual treatment programme for male IPV perpetrators depending on the presence of PAU. Methods: The sample was composed of 641 male IPV perpetrators who completed a specialized individual treatment programme for gender violence perpetrators. All of the participants were followed for one year after treatment completion. Results: The effects of PAU on treatment success were evaluated by means of multiple logistic regression analyses. The full model was reliable (χ2 = 10.243; df = 3; p = .016), and overall, 88.8% of the predictions were accurate. The findings indicated that the probability of successful treatment does not depend on the presence of PAU. Conclusions: The relationship between IPV perpetration and PAU is highly complex, and several underlying mechanisms should be further evaluated. Accordingly, interventions should not only screen for alcohol consumption but also for all individual characteristics that might necessitate tailored treatment.Publication Open Access Differential psychopathological profile of male intimate partner violence perpetrators depending on problematic alcohol use(Elsevier, 2021) Siria Mendaza, Sandra; Leza González, Leire; Fernández-Montalvo, Javier; Echauri, José Antonio; Azcárate, Juana M.; Ciencias de la Salud; Osasun ZientziakObjective: This study explored the differential psychopathological profile between male perpetrators of intimate partner violence (IPV) with and without problematic alcohol use (PAU). Method: A sample of 981 men was recruited from a specialized IPV perpetrators treatment programme. All of them were assessed with the Symptom Checklist-90-Revised (SCL-90-R), the State-Trait Anger Expression Inventory-2 (STAXI-2), and the Millon Clinical Multiaxial Inventory-III (MCMI-III). Comparisons between perpetrators with (n = 125) and without (n = 856) PAU on all the variables studied were carried out. Results: Perpetrators with PAU were less frequently employed and had higher rates of previous psychiatric history and childhood family violence. Moreover, they presented with higher levels of cognitive biases about women and violence. On a psychopathological level, participants with PAU reported significantly higher scores on the SCL90-R, on the STAXI-2, and on almost all the MCMI-III scales than did those without PAU. The multivariate logistic regression analyses showed that the main variables related to PAU were as follows: higher levels of previous psychiatric history, distorted thoughts about women, depression, drug dependence, and various personality disorders (bipolar, dysthymia, antisocial, avoidant, borderline, and schizotypal); and lower scores on internal control, anger reaction, paranoid ideation, and schizoid personality disorders. Discussion: IPV perpetrators with PAU have a more severe psychopathological profile than those without PAU. Additionally, several variables along with PAU may have contributed to the development of IPV. Therefore, tailored interventions should be developed for those perpetrators with PAU.
