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 Zientziak
Background: 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.

Adolescents adjudicated for sexual offending: differences between sexual reoffenders and sexual non-reoffenders
(SAGE Publications, 2021) Siria Mendaza, Sandra; Echeburúa, Enrique; Amor, Pedro; Ciencias de la Salud; Osasun Zientziak
Although a very small group of adolescents adjudicated for sexual offending (ASO) will persist into adulthood, the use of official records of sexual recidivism after long-term follow-up periods underrates the repetition of sexually coercive behaviors during adolescence. Additionally, limited research has considered sexual reoffending as a criterion to classify this heterogeneous population. The aims of this study were to determine the prevalence of ASO who engaged in repetitive sexual offending before their adjudication, and to use it as a classification criterion to examine the differential characteristics associated with each group. A sample of 73 adjudicated ASO in Spain was examined. They were divided into sexual reoffenders (SR) (n = 34) and sexual nonreoffenders (SNR) (n = 39). An ex post facto research design was carried out. Assessments included reviews of official files, interviews with professionals in charge, and interviews with the ASO in which the Interpersonal Reactivity Index (IRI) was administered. Descriptive analyses were conducted for all variables and Odds Ratio (OR) was used to compare intergroup differences. Results showed that SR had 12.95 times the odds of sexual victimization, 6.91 times the odds of having lived in a sexualized family environment, and 3 times the odds of bullying victimization. Deviant sexual fantasies were exclusively present among SR (44%). Significant differences between groups were also found in some sexual crime variables but not on the empathy scale. These results have implications for the distinction between ASO who have repeatedly engaged in sexually coercive behavior and those who engaged in a single event of sexual offending. The identification of specific risk factors and criminogenic needs for each group would benefit court decisions and more tailored interventions.

Adolescents adjudicated for sexual offending: a comparison between sex-only and sex-plus
(Springer, 2021) Siria Mendaza, Sandra; Echeburúa, Enrique; Amor, Pedro; Sociología y Trabajo Social; Soziologia eta Gizarte Lana; Institute for Advanced Social Research - ICOMMUNITAS
Introduction One of the most consolidated classifcations of adolescents adjudicated for sexual ofending (ASO) is based on their antisocial behavior background. This allows identifying sex-only and sex-plus ASO. However, limited research related to this classifcation has been focused on relevant risk factors, such as sexual development, and none of them has been conducted in Spain. Methods A cross-sectional study was carried out with a sample of 73 ASO. Data collection took place between 2013 and 2015. They were divided into sex-only (n=33) and sex-plus (n=40). Assessments included reviews of ofcial fles, interviews with professionals in charge, and interviews with the ASO. Descriptive and inferential analyses were conducted to compare intergroup diferences. Results No signifcant diferences between groups in family background, history of maltreatment, and sexual development variables were found. Sex-plus had a signifcantly higher prevalence of disruptive behavior at school, school absenteeism, substance consumption, and antisocial misconduct with peers. Signifcant diferences between groups were also found in some sexual crime variables. Logistic regression analyses showed that antisocial behavior with peers and school absenteeism were related to sex-plus. Conclusions These fndings highlight the importance of assessing sexual development and family background when intervening with ASO. Sexual development-related variables should be further examined to understand their involvement in sexually coercive behaviors. Policy Implications The identifcation of specifc criminogenic needs for each ofense pathway would beneft court decisions and more tailored interventions to reduce recidivism. These treatments should include family interventions.

Lifetime suicidal-related behaviour among patients in treatment for substance use disorder: a cross-sectional study
(Elsevier, 2022) Siria Mendaza, Sandra; Leza González, Leire; López-Goñi, José Javier; Fernández-Montalvo, Javier; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Suicidal-related behaviours are an important concern in individuals who present with substance use disorders (SUDs). The distinction among the specific characteristics of the different patients might help to improve prevention strategies. We describe and compare the sociodemographic characteristics, severity of addiction, and psychopathology of the participants depending on the severity of their lifetime suicidal behaviour. In addition, we examine whether the number of suicide attempts can be estimated based on the variables that differentiate the groups. A sample of 318 men and 86 women who sought treatment for addiction were assessed. The sample was divided into: no ideation or attempts, suicidal ideation, one suicide attempt, and two or more suicide attempts. The group with two or more suicide attempts exhibited a greater severity in the addiction profile. The group with one suicide attempt presented a higher psychopathological symptomatology at the time of the assessment. The severity of the Psychiatric area was related to the group with two or more attempts and to the number of suicide attempts. The presence of any number of attempts is associated with greater severity of addiction. Providing specific intervention strategies for SUD patients depending on their suicidal behaviours is promising for clinical application.

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 Zientziak
Objective: 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.

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 Zientziak
Objetivo: 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.

Agresores sexuales juveniles: ¿existe un tratamiento eficaz?
(Universidad de Granada, 2011) Sánchez Herrero, Nahikari; Siria Mendaza, Sandra; Sociología y Trabajo Social; Soziologia eta Gizarte Lana; Institute for Advanced Social Research - ICOMMUNITAS
En los últimos años comienza a ser habitual la aparición en los medios de comunicación de noticias relacionadas con menores que agreden sexualmente. Estas noticias causan una gran alarma social y generan un debate sobre la necesidad de endurecer la legislación sobre menores vigente en la actualidad. Pero realmente ¿qué sabemos acerca de estos menores? ¿Cuáles son las causas de su conducta? ¿Qué tratamientos se les aplica? Y ¿qué reincidencia presentan? Es objetivo prioritario y fundamental de la Criminología dar respuesta a estas preguntas, estudiando en profundidad a agresores, víctimas, conducta delictiva y contexto social en el que se lleva a cabo, para elaborar programas adecuados de intervención y evitar victimizaciones innecesarias. A través del acercamiento teórico que se presenta en este estudio se van a mostrar aquellos factores de riesgo que pueden hacer que un menor llegue a cometer algún tipo de abuso o agresión sexual hacia niños o hacia adultos. Por otra parte se mostrarán los tratamientos existentes en la actualidad dirigidos a estos menores, así como la idoneidad de los mismos.

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 Zientziak
This 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.

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 Zientziak
Aims: 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.

Characteristics and risk factors in juvenile sexual offenders
(Colegio Oficial de Psicólogos del Principado de Asturias, 2020) Siria Mendaza, Sandra; Echeburúa, Enrique; Amor, Pedro; Ciencias de la Salud; Osasun Zientziak
Características y factores de riesgo en jóvenes ofensores sexuales. Antecedentes: la violencia sexual cometida por adolescentes supone alrededor del 7% de los delitos sexuales denunciados anualmente en España. Sin embargo, la investigación con jóvenes ofensores sexuales (JOS) en población española es casi inexistente. En este trabajo se analizan los factores de riesgo relacionados con la violencia sexual cometida por adolescentes. Método: los participantes fueron 73 adolescentes (M = 15.68 años, DT = 1.12, rango entre 14 y 18) que estaban cumpliendo una medida judicial por delitos contra la libertad sexual en diferentes comunidades autónomas españolas. En este estudio descriptivo se emplearon diversos métodos para recoger los datos: revisión de expedientes, autoinformes y una entrevista aplicada a los JOS y a los profesionales implicados. Resultados: se analizaron los factores de riesgo vinculados a la historia familiar, a determinadas características de personalidad y al desarrollo de una “sexualización inadecuada” (96% de los casos) relacionada, fundamentalmente, con un inicio precoz en el consumo de pornografía (70%), un ambiente familiar sexualizado (26%) y la presencia de victimización sexual durante la infancia (22%). Conclusiones: los resultados son coherentes con investigaciones internacionales. El desarrollo de la sexualización desde la infancia debe ser examinado en mayor profundidad con respecto a la violencia sexual.
