The main objective of this study was to systematically and meta-analytically review the scientific literature on the prevalence of psychopathy in the general adult population. A search in PsycInfo, MEDLINE, and PSICODOC identified 15 studies published as of June 2021. Altogether, 16 samples of adults totaling 11,497 people were evaluated. Joint prevalence rates were calculated using reverse variance heterogeneity models. Meta-regression analyses were conducted to examine whether the type of instrument, sex, type of sample, and country influenced prevalence. The meta-analytical results obtained allow us to estimate the prevalence rate of psychopathy in the general adult population at 4.5%. That being said, this rate varies depending on the participants' sex (higher in males), the type of sample from the general population (higher in samples from organizations than in community samples or university students), and the type of instrument used to define psychopathy. In fact, using the PCL-R, which is currently considered the “gold standard” for the assessment and definition of psychopathy, the prevalence is only 1.2%. These results are discussed in the context of the different theoretical perspectives and the existing problems when it comes to defining the construct of psychopathy.

Resumen: Las adaptaciones españolas de la Escala de Deseabilidad Social de Marlowe-Crowne (M-C SDS) han sido baremadas con estudiantes universitarios y adultos evaluados en contextos de selección/promoción laboral. Dada la influencia de la edad y el contexto en la M-C SDS, estos baremos no son apropiados para adultos voluntarios. Se presentan por primera vez datos normativos y de fiabilidad y una versión breve de la adaptación de la M-C SDS de Ávila Espada y Tomé Rodríguez obtenidos con adultos voluntarios españoles (N = 575). Los índices de consistencia interna de la M-C SDS fueron adecuados (alfa = .72-.80). Las diferencias estandarizadas en sus puntuaciones entre adultos voluntarios y estudiantes universitarios o adultos de selección/promoción alcanzaron tamaños del efecto medianos (d = 0.46 y 0.70), lo que justifica la creación de baremos específicos para adultos voluntarios. En dos submuestras independientes de adultos voluntarios, una versión de 18 ítems obtuvo índices de consistencia interna para sus ítems mejores que los de los 33 ítems de la escala completa y que no implicaba una pérdida significativa de fiabilidad (alfa = .72 y .80) ni de validez nomológica. Se ofrecen baremos globales y separados por grupos de edad para las versiones breve y completa de la M-C SDS. Palabras clave: Deseabilidad social; medidas de personalidad; baremos de test; versiones breves de test. Title:The Marlowe-Crowne Social Desirability Scale: norms for the Spanish general population and development of a short version Abstract: The Spanish adaptations of the Marlowe-Crowne Social Desirability Scale (M-C SDS) were normed on samples of university students or of adults assessed in personnel selection/promotion settings. Given the influence of age and assessment setting on the M-C SDS, these norms are inadequate for adult volunteers. This is the first study that provides normative and reliability data and a short form of Ávila Espada and Tomé Rodríguez's Spanish adaptation of the M-C SDS with Spanish adult volunteers (N = 575). Internal consistency estimates for the M-C SDS were adequate (alphas = .72-.80). The standardized differences in M-C SDS scores between the adult volunteer sample and university student or personnel selection/promotion samples reached values of medium size (d = 0.46 and 0.70). This result supports the development of specific norms for adult volunteers. In two independent subsamples of adult volunteers, a short form of 18-items showed internal consistency indices for its items that were higher than those for the 33 items of the complete scale. This short form did not involve a significant loss of reliability (alphas = .72 and .80) or nomological validity. Global norms and norms for age groups are provided for the short and complete forms of the M-C SDS.

El objetivo principal de este trabajo fue revisar el estado de la investigación psicopatológica del duelo complicado en población adulta de España. Una búsqueda sistemática en PsycINFO, PsycArticles, PTSDpubs y PSICODOC identificó 13 estudios en los que, en conjunto, se había evaluado a 1,655 adultos. Los resultados de esta revisión ponen de manifiesto que no existe consenso en el diagnóstico de duelo complicado, en el uso de instrumentos de detección ni en los factores de riesgo y protección del duelo complicado. La prevalencia media ponderada basada en 6 de los estudios revisados fue de 21,53%. Tomando en consideración el tipo de instrumento de medida del duelo utilizado, se obtuvo una prevalencia de 7,67-10,68% en aquellos estudios que utilizaban instrumentos diagnósticos y de 28,77% en los instrumentos sintomáticos. Los resultados indican que el duelo complicado se relaciona con: un menor nivel socioeconómico y situación laboral desfavorable, la pérdida de un hijo o cónyuge, menor edad del fallecido, vulnerabilidad psicológica previa, consumo de psicofármacos y comorbilidad con otros trastornos. El apoyo social, los cuidados paliativos, las estrategias de afrontamiento centradas en el problema, el empleo de actividades agradables y la trascendencia o espiritualidad se presentan como factores protectores.   The main objective of this research was to review the status of the psychopathological investigation of complicated grief in adult population of Spain. A systematic review on PsycINFO, PsycArticles, PTSDpubs, and PSICODOC databases identified 13 studies in which, overall, 1.655 adults had been evaluated. The results of this review show that there is no consensus in the diagnosis of complicated grief, in the use of detection instruments, or in the risk and protective factors for complicated grief. The weighted mean prevalence based on 6 of the reviewed studies was 21.53%. Taking into account the type of grief measurement used, a prevalence of 7.67-10.68% was obtained in those studies that used diagnostic instruments and 28.77% in the ones using symptomatic instruments. The results indicate that complicated grief is related to: a lower socioeconomic level and unfavorable work situation, the loss of a child or spouse, younger age of the deceased, previous psychological vulnerability, the use of psychotropic medication and comorbidity with other disorders. Social support, palliative care, problem-centered coping strategies, the use of pleasant activities, and transcendence or spirituality are shown as protective factors.

BackgroundScientific literature on posttraumatic growth (PTG) after terrorist attacks has primarily focused on persons who had not been directly exposed to terrorist attacks or persons who had been directly exposed to them, but who were assessed few months or years after the attacks.MethodsWe examined long-term PTG in 210 adults directly exposed to terrorist attacks in Spain a mean of 29.6 years after the attacks (range: 2–47 years). The participants had been injured by a terrorist attack (38.6%) or were first-degree relatives of people who had been killed or injured by a terrorist attack (41.4% and 20%, respectively). They completed diagnostic measures of emotional disorders and measures of PTSD and depression symptomatology, optimism, and PTG.ResultsMultiple regression analyses revealed gender differences (women reported higher levels of PTG than did men) and a positive linear relationship between PTG and cumulative trauma after the terrorist attack. Some PTG dimensions were significantly associated with PTSD symptomatology, these associations being linear, not curvilinear. However, PTG was not associated with depression symptomatology, diagnosis of emotional disorders, age, elapsed time since the attack, or optimism. In comparison with survivors assessed 18 years after the 1995 Oklahoma City bombing, Spanish victims of terrorism showed higher levels of appreciation of life, but lower levels of relating to others and spiritual change.ConclusionThe findings underscore the influence of gender on PTG and provide support to the hypothesis that some emotional distress may be a necessary condition of PTG. Future studies on PTG after terrorist attacks should take into consideration the characteristics of the terrorist attack itself and the contexts of violence and threat in which it occurred. The political, social, and cultural characteristics of the community affected by it and the profile and characteristics of other traumatic events suffered after the attack should also be taken into account in further research.

Ciento veinte víctimas del terrorismo que habían sufrido un atentado como media 18 años antes y que presentaban sintomatología o trastorno de estrés postraumático (TEPT) fueron aleatorizadas a 16 sesiones de terapia cognitivoconductual centrada en el trauma (TCC-CT) o a lista de espera. Ninguna de las víctimas que completó el tratamiento presentaba un diagnóstico de TEPT en el postratamiento; estas víctimas mostraban niveles de sintomatología de estrés postraumático significativamente menores en el postratamiento que en el pretratamiento, con una diferencia prepost grande (d = 1.39) y un 78.3% de ellas mostraban niveles normales en el postratamiento. Estos resultados fueron significativamente mejores que los del grupo control, siendo la diferencia tratamiento-control grande (d = 0.91). La TCC-CT es eficaz y representa actualmente el tratamiento de elección para víctimas del terrorismo que sufren TEPT o sintomatología de estrés postraumático, incluso a muy largo plazo, entre 6 y 51 años después del atentado. Because time does not heal all wounds: Efficacy of trauma-focused cognitive behavioral therapy for very long-term posttraumatic stress in victims of terrorism A B S T R A C TOne hundred and twenty victims of terrorism who had suffered a terrorist attack an average of 18 years ago and who mainly had posttraumatic stress disorder (PTSD) or posttraumatic stress symptomatology were randomized to a 16-session trauma-focused cognitive-behavioral therapy (TF-CBT) or to a waiting-list control group. No victim who completed treatment had a PTSD diagnosis at posttreatment; these victims showed significantly lower levels of posttraumatic stress symptomatology at posttreatment than at pretreatment, with a large pre-posttreatment difference (d = 1.39), and 78.3% of them showed normal levels of symptomatology at posttreatment. These results were significantly better than those of the control group, with a large treatment-control difference (d = 0.91). TF-CBT is efficacious and is currently the treatment of choice for victims of terrorism who suffer from PTSD or posttraumatic stress symptomatology, even in the very long term, between 6 and 51 years after the terrorist attack.Para citar este artículo: Gesteira, C., García-Vera, M.
