Factors associated with violence among Japanese patients with schizophrenia prior to psychiatric emergency hospitalization: A case-controlled study

Prevalence of Aggressive or Violent Behaviour in Thai Patients with Schizophrenia: a Cross-Sectional Study

“…24,25 However, in Japanese patients with schizophrenia, violent behaviour is related to schizophrenic symptoms rather than antisocial traits or substance use disorder. 13 Similarly, the present study showed no association of substance use disorder or personality traits or disorders with schizophrenia in our patients. Rather, aggressive or violent behaviour may be caused by several factors before, during, and after periods of active illness and may be affected by cultural and racial diversity.…”

“…Rather, aggressive or violent behaviour may be caused by several factors before, during, and after periods of active illness and may be affected by cultural and racial diversity. 1,13 The present study had some limitations. The sample size was small; a larger sample is needed to confirm these findings.…”

“…11 Aggressive or violent behaviour in patients with schizophrenia may be a response to psychotic delusions (especially paranoid or persecutory delusions), hallucinations, or misperceptions, and therefore a psychotic form of self-defense. 12 Factors associated with aggressive or violent behaviours in patients with schizophrenia include severity of psychotic symptoms, personality dimensions, substance abuse, and mentalising abilities, 13,14 whereas sociodemographic risk factors include economic deprivation 15 and social living status. 16 There are few studies on factors associated with aggressive development, especially in Asian patients with schizophrenia.…”

Establishing the “Fit” between the Patient and the Therapy: The Role of Patient Gender in Selecting Psychological Therapy for Distressing Voices

“…Consequently, it is surprising that so little attention has been paid to gender within the literature, especially the gender of the hearer. The existing literature on hearer gender suggests that differences are evident: voice hearing is more common in women (Rector and Seeman, 1992 ; Murphy et al, 2010 ), who have a higher frequency of voices (Sharma et al, 1999 ) and a more delusional interpretation of these experiences (Gonzalez et al, 2008 ); whereas voice hearing begins at an earlier age for men and is more persistent (Gonzalez et al, 2008 ). With respect to gender of the voice, the “dominance” of the male voice seems evident for both men and women (Legg and Gilbert, 2006 ).…”

Are patterns of violence and aggression at presentation in patients with first‐episode psychosis temporally stable? A comparison of 2 cohorts

“…found differences in the associations with aggressive behaviour among acutely ill inpatients compared to patients with lower levels of positive symptoms. Furthermore caution is advised when interpreting associations of violence and psychosis with regard to the influence of socio-cultural and ethnic differences including variations in rates of substance misuse and antisocial traits between populations(Imai, Hayashi, Shiina, Sakikawa, & Igarashi, 2014).In their systematic review and meta-analysis,Large and Nielssen (2011) found that 34.5% of first-episode psychosis patients demonstrated violence. The approximation of one-third of patients in the first episode of psychosis exhibiting violent behaviour was consistent with our findings and should be considered relative to the 9.9% violence rate in schizophrenia and 1.6% violence rate in the general population found byFazel et al (2009) in their systematic review.…”
