Factors related to physical violence experienced by parents of persons with schizophrenia in Japan

Violence Against Parents by Adult Children: A Systematic Literature Review of Empirical Studies

Violence against parents by adult children is the abuse of physical, psychological, social, or economic power committed by a grown-up child against his/her parent or foster parent with the intention of achieving a specific goal such as control, subordination, economic gains, or internal satisfaction. It encompasses physical, psychological, sexual, and financial violence, neglect, and property crime. This paper aims to systematically review the literature on violence against parents by adult children. With the use of a range of keywords, the databases Web of Science, SAGE, SpringerLink, Taylor and Francis online, PubMed, EBSCOhost, JSTOR, ProQuest Ebook Central, PsycInfo, Routledge, and Science Direct were reviewed according to the PRISMA Statement. A review of the literature by key authors and contributions using the snowball method followed. The inclusion criteria were empirical journal papers and books published in English between 1990 and 2023 that address violence against parents by adult children. Exclusion criteria included reviews, commentaries, abstracts, and any publications that address the subject topic in a language other than English. The searches returned 39 relevant contributions. Four common themes emerged across the field: the prevalence and characteristics of violence against parents by adult children, parents' responses and experiences of violence by adult children, social perceptions of (older) parent abuse, and consequences and prevention of violence against parents by adult children. Findings of the literature review show that violence against parents is an under-researched phenomenon and points to the need for further research, including the prevention, detection, consequences, and treatment of such violence.

Delusions and Delinquencies: A Comparison of Violent and Non-Violent Offenders With Schizophrenia Spectrum Disorders

The relationship between schizophrenia spectrum disorders (SSD) and violent offending has long been the subject of research. The present study attempts to identify the content of delusions, an understudied factor in this regard, that differentiates between violent and non-violent offenses. Limitations, clinical relevance, and future directions are discussed. Employing a retrospective study design, machine learning algorithms and a comprehensive set of variables were applied to a sample of 366 offenders with a schizophrenia spectrum disorder in a Swiss forensic psychiatry department. Taking into account the different contents and affects associated with delusions, eight variables were identified as having an impact on discriminating between violent and non-violent offenses with an AUC of 0.68, a sensitivity of 30.8%, and a specificity of 91.9%, suggesting that the variables found are useful for discriminating between violent and non-violent offenses. Delusions of grandiosity, delusional police and/or army pursuit, delusional perceived physical and/or mental injury, and delusions of control or passivity were more predictive of non-violent offenses, while delusions with aggressive content or delusions associated with the emotions of anger, distress, or agitation were more frequently associated with violent offenses. Our findings extend and confirm current research on the content of delusions in patients with SSD. In particular, we found that the symptoms of threat/control override (TCO) do not directly lead to violent behavior but are mediated by other variables such as anger. Notably, delusions traditionally seen as symptoms of TCO, appear to have a protective value against violent behavior. These findings will hopefully help to reduce the stigma commonly and erroneously associated with mental illness, while supporting the development of effective therapeutic approaches.

Machine Learning for prediction of violent behaviors in schizophrenia spectrum disorders: a systematic review

Background

Schizophrenia spectrum disorders (SSD) can be associated with an increased risk of violent behavior (VB), which can harm patients, others, and properties. Prediction of VB could help reduce the SSD burden on patients and healthcare systems. Some recent studies have used machine learning (ML) algorithms to identify SSD patients at risk of VB. In this article, we aimed to review studies that used ML to predict VB in SSD patients and discuss the most successful ML methods and predictors of VB.

Methods

We performed a systematic search in PubMed, Web of Sciences, Embase, and PsycINFO on September 30, 2023, to identify studies on the application of ML in predicting VB in SSD patients.

Results

We included 18 studies with data from 11,733 patients diagnosed with SSD. Different ML models demonstrated mixed performance with an area under the receiver operating characteristic curve of 0.56-0.95 and an accuracy of 50.27-90.67% in predicting violence among SSD patients. Our comparative analysis demonstrated a superior performance for the gradient boosting model, compared to other ML models in predicting VB among SSD patients. Various sociodemographic, clinical, metabolic, and neuroimaging features were associated with VB, with age and olanzapine equivalent dose at the time of discharge being the most frequently identified factors.

Conclusion

ML models demonstrated varied VB prediction performance in SSD patients, with gradient boosting outperforming. Further research is warranted for clinical applications of ML methods in this field.

Patient's disability and caregiver burden among Chinese family caregivers of individual living with schizophrenia: mediation effects of potentially harmful behavior, affiliate stigma, and social support

Evidence on the associations between patient's disability and caregiver burden among Chinese family caregivers of individual living with schizophrenia is lacking. This study aimed at explore the underlying mechanisms between patient's disability and caregiver burden among Chinese family caregivers of individual living with schizophrenia. A cross-sectional study was carried out in four Chinese cities (Wuhan, Changsha, Guangzhou, and Shenzhen), between April, 2021 and March, 2022. A total of 493 patients and their family caregivers were invited to report related data. The Zarit burden interview, WHODAS 2.0, the Potentially harmful behavior scale, the Affiliate Stigma Scale, and the Multidimensional Scale of perceived social support were used to collect data. Linear regression analysis and bootstrapping analysis were conducted. The adjusted regression results showed that patients' disability (B = 0.616; 95% CI: 0.479-0.753), potentially harmful behavior on caregivers (B = 0.474; 95% CI: 0.232-0.716), and caregiver's low social support (B = -0.079; 95% CI: -0.158- -0.002), high level of affiliate stigma (B = 13.045; 95% CI: 10.227-15.864) were associated with higher level of caregiver burden (p < 0.05). In the mediation model, the direct path from patient's disability to caregiver burden (B = 0.428, β = 0.371, p < 0.001) was significant and positive. Patient's disability was indirectly associated with caregiver burden through patient's potentially harmful behavior, caregiver's affiliate stigma, and social support, the standardized regression coefficients ranged from 0.026-0.049 (p < 0.05). Patient's potentially harmful behavior, caregiver's affiliate stigma, and social support mediated the relationship between patients' disability and caregiver burden. Future intervention studies designed to target these three factors may be beneficial for family caregivers of persons living with schizophrenia.

Prevalence of violence by people living with severe mental illness against their relatives and its associated impacts: A systematic review

INTRODUCTION

Violence perpetration by adults with severe mental illness (SMI) specifically towards their relatives is a sensitive topic and a largely neglected area that has consequences and implications for different stakeholders, including healthcare providers. This paper sought to systematically review the relevant literature, to identify the types and rates of violence by people with SMI against their relatives, and to develop a detailed understanding of its reported impacts.

METHODS

A systematic review, registered with PROSPERO (registration number CRD42019150784), was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The review comprised searches of Medline, Embase, PsycInfo and CINAHL databases, supplemented by manual searches. Data from 38 papers using mixed methodologies were reviewed.

RESULTS

Key findings highlighted that relatives experienced different types of violence, including physical, verbal, psychological, financial violence, and violence directed towards property. Different types often co-occurred. Mothers were the group most likely to report being victims, compared with other relatives. Reported impacts of violence on relatives included mental ill health (e.g., psychological distress, post-traumatic stress symptoms) and the deterioration, and in some cases the permanent breakdown, of family relationships and the family unit. However, relatives often continued to provide a framework of support for patients, despite risks to their own safety.

CONCLUSION

Findings speak to the importance of future research extending the focus beyond the identified victimised relative or perpetrator, to also consider the impacts of violence at the family-wide level, and to improve the outcomes of families exposed to and dealing with violence by individuals living with SMI.

Nurses', patients', and informal caregivers' attitudes toward aggression in psychiatric hospitals: A comparative survey study

Attitudes toward aggression is a controversial phenomenon in psychiatry. This study examined and compared attitudes toward patient aggression in psychiatric hospitals from the perspectives of nurses, patients and informal caregivers and identified factors associated to these attitudes. A total of 2,424 participants completed a self-reported instrument regarding attitudes toward aggression (12-items Perception of Aggression Scale; POAS-S). We analysed data from nurses (n = 782), patients (n = 886), and informal caregivers (n = 765). Pearson's r correlations were used to examine associations between variables. Differences between group scores were analysed using ANOVA/MANOVA with post-hoc Sheffe tests. Multivariate logistic regression models and logistic regression analysis were used to examine the effects of respondents' characteristics on their attitudes toward aggression. Nurses had significantly more negative and less tolerant perceptions toward aggression (mean [SD] 47.1 [7.5], p<0.001) than the patients (mean [SD] 44.4 [8.2]) and the informal caregivers (mean [SD] 45.0 [6.9), according to the POAS-S total scores. The same trend was found with the dysfunction and function sub-scores (mean [SD] 25.3 [4.1] and 15.0 [3.6], respectively); the differences between the groups were statistically significant (p <0.001) when nurses' scores were compared to those of both the patients (mean [SD] 23.7 [5.3] and 14.0 [4.1], respectively) and the informal caregivers (mean [SD] 24.4 [4.2] and 13.9 [3.5], respectively). The study offers new understanding of aggressive behavior in different treatment settings where attitudes toward patient behavior raises ethical and practical dilemmas. These results indicate a need for more targeted on-the-job training for nursing staff, aggression management rehabilitation programs for patients, and peer-support programs for informal caregivers focused on patient aggression.

Serious mental illness and incidents between adult children and parents responded to by police

BACKGROUND

Despite a sizable minority of persons with serious mental illness (SMI) acting aggressively toward family members, little is known about this topic. The objectives of the present analyses are to examine the association of offenders' SMI status with offender behaviors and victim outcomes and to compare the immediate contextual characteristics of incidents involving offenders with and without SMI.

METHODS

Using a cross-sectional design, all incidents of domestic violence to which police were called between adult children and their parents in Philadelphia, PA, in 2013 (N = 6191) were analyzed. Additionally, incidents in which the offender was indicated to have SMI (n = 327) were matched with a sample of incidents in which the offender was not indicated to have SMI (n = 327).

RESULTS

Offenders having SMI was not associated with using a bodily weapon or gun, threatening victims, or damaging property. Offenders having SMI was associated with a decreased risk of offenders using a non-gun external weapon and victims being observed to have a complaint of pain or visible injuries. When offenders had SMI, conflict was less likely to focus on family issues and more likely to focus on offenders' behaviors and to involve contextual characteristics related to mental illness.

CONCLUSIONS

Efforts to prevent gun and other violence between non-intimate partner family members should target factors more strongly associated with violence than SMI (e.g. history of domestic violence, substance abuse). Intervening in family aggression by persons with SMI likely requires addressing unique circumstances these parties experience.

Violent and non-violent offending in patients with schizophrenia: Exploring influences and differences via machine learning

OBJECTIVES

The link between schizophrenia and violent offending has long been the subject of research with significant impact on mental health policy, clinical practice and public perception of the dangerousness of people with psychiatric disorders. The present study attempts to identify factors that differentiate between violent and non-violent offenders based on a unique sample of 370 forensic offender patients with schizophrenia spectrum disorder by employing machine learning algorithms and an extensive set of variables.

METHODS

Using machine learning algorithms, 519 variables were explored in order to differentiate violent and non-violent offenders. To minimize the risk of overfitting, the dataset was split, employing variable filtering, machine learning model building and selection embedded in a nested resampling approach on one subset. The best model was then selected, and the most important variables applied on the second data subset.

RESULTS

Ten factors regarding criminal and psychiatric history as well as clinical, developmental, and social factors were identified to be most influential in differentiating between violent and non-violent offenders and are discussed in light of prior research on this topic. With an AUC of 0.76, a sensitivity of 72% and a specificity of 62%, a correct classification into violent and non-violent offences could be determined in almost three quarters of cases.

CONCLUSIONS

Our findings expand current research on the factors influencing violent offending in patients with SSD, which is crucial for the development of preventive and therapeutic strategies that could potentially reduce the prevalence of violence in this population. Limitations, clinical relevance and future directions are discussed.

Violence by Persons with Serious Mental Illness Toward Family Caregivers and Other Relatives: A Review

Persons living with serious mental illness (SMI) are at a modestly increased risk of committing violence and are disproportionately likely to target family members when they do commit violence. In this article, we review available evidence regarding violence by persons with SMI toward family members, many of whom are caregivers. Evidence suggests that a sizable minority of family members with high levels of contact with persons with SMI have experienced violence, with most studies finding rates of past year victimization to be 20% or higher. Notable risk factors for family violence pertaining specifically to persons with SMI include substance use, nonadherence to medications and mental health treatment, history of violent behavior, and recent victimization. Notable risk factors pertaining specifically to the relationships between persons with SMI and family members include persons with SMI relying on family members for tangible and instrumental support, family members setting limits, and the presence of criticism, hostility, and verbal aggression. As described in qualitative studies, family members often perceive violence to be connected to psychiatric symptoms and inadequate treatment experiences. We argue that promising strategies for preventing violence by persons with SMI toward family members include (1) better engaging persons with SMI in treatment, through offering more recovery-oriented care, (2) strengthening support services for persons with SMI that could reduce reliance on family members, and (3) supporting the capabilities of family members to prevent and manage family conflict. The available interventions that may be effective in this context include McFarlane's Multifamily Group intervention and the Family-to-Family educational program.

Pilot Study of a Video-Based Educational Program to Reduce Family Violence for Parents of Adult Children with Schizophrenia

This pilot study evaluated a video-based educational program for improving communication skills and reducing family violence between parents and their adult children with schizophrenia. We used a one group pretest-posttest design. The program included a main 90-min video and six stories, each 20-30 min long. We made assessments at baseline and program completion (three months after baseline). Sixty-six parent participants completed the intervention. The average frequency of acts of family violence significantly decreased from 11.4 (SD = 26.2) at pretest to 5.1 (SD = 13.2) at posttest (p = 0.016). Our findings showed significant improvements regarding expressed emotion, psychological distress, family empowerment, and hope, demonstrating preliminary positive results for this video-based educational program. The program was shown to be feasible for support/educational groups of family members of adults with mental disorders to deliver and may also be useful for practitioner-led educational groups for families in public health centers or medical settings to offer.

Experiences of Family Caregivers of Individuals With Chronic Psychiatric Illness in Turkey: A Qualitative Study

The purpose of the current descriptive qualitative study was to reveal experiences of family caregivers of individuals with chronic psychiatric illness. Family caregivers who provided care to 16 individuals with chronic mental illness were interviewed. Three themes emerged from the interviews: Illness Management, The Caregiver's World: Changes and Effects, and Coping From the Caregiver's Point of View. Understanding the experiences of family caregivers contributes to content development of family intervention programs. [Journal of Psychosocial Nursing and Mental Health Services, 58(3), 38-46.].

Violence against primary caregivers of people with severe mental illness and their knowledge and attitudes towards violence: A cross-sectional study in China

PURPOSE

The purpose of this study is to investigate the current situation of violence on primary caregivers of people with severe mental illness outside the hospital and the cognition of primary caregivers about violence among mental patients.

METHODS

A self-designed questionnaire was used to investigate the primary caregivers (N = 208) of people with severe mental illness in a psychiatric hospital in Beijing.

RESULTS

The incidence rate of violence suffered by primary caregivers was 74.03%, of which 61.54% had experienced verbal attacks, 54.33% had experienced threats, and 45.19% experienced physical attacks. Physical violence, mainly by unarmed attacks, has resulted in soft tissue injury and pain in the majority of caregivers. Multiple admission times, a lower educational level, single in marital status and involuntary hospitalizations were risk factors; growing older was protective factor. The causes of violence were dominated by mental symptoms in 120 cases (57.69%). Tolerance and avoidance were the coping styles of most caregivers adopted after violence, accounting for 51.44%. Furthermore, most of primary caregivers have limited knowledge of violence and adopted an attitude of pessimism towards patients' violence.

CONCLUSIONS

It was reported that violence was suffered by primary caregivers of persons with severe mental illness outside the hospital. The study indicated that formulating reasonable nursing intervention, providing health education as well as organizing training towards violence of patients are required to play an important role in effectively preventing and reducing the violence among the people with severe mental illness in China. More information and support needs to be obtained to help caregivers fulfill their duty of care outside the hospital.

Perceptions of Stages of Family Violence and their Perceived Solutions in Persons with Schizophrenia

Background:

Family violence committed by persons with schizophrenia is a serious problem in the context of the accelerated deinstitutionalization in Japan. Community nurses could play an important role in resolving family violence by persons with schizophrenia.

Objective:

This study aimed to clarify the reasons for family violence as perceived by adult children with schizophrenia and ways to resolve this problem.

Methods:

A qualitative descriptive design was employed. Group interviews with 10 participants—five individuals with schizophrenia and five parents of adult children with schizophrenia-were conducted. Transcriptions were segmented according to the following three research questions: “How do parents recognize and cope with violence committed by persons with schizophrenia?,” “How do persons with schizophrenia perceive committing violence toward their parents and how do they change themselves after doing so?” and “How do persons with schizophrenia perceive ways to resolve the issue of violence toward parents?” The data were categorized and subcategorized based on the similarity of codes and organized in chronological order. Categories concerning reasons for violence and the subsequent changes in persons with schizophrenia made up the stages of their experiences.

Results:

Parents could not understand the reasons for violence committed by persons with schizophrenia. Experiences of committing violence and changes after violence as perceived by persons with schizophrenia involved the following five stages: complicated causes of occurrence, environment conducive to violence, onset of violence, gaining power, and regret and growth. Persons with schizophrenia wanted to be observed from a distance and were desirous of establishing relationships beyond the home.

Conclusion:

It is necessary for nurses to bridge the gap between patients and their parents by serving as a communication channel between them. In this way, there is hope to promote recovery even if the patient with schizophrenia commits violent acts toward the parent.

Risk of Posttraumatic Stress Disorder and Its Relationship With Perceived Social Support Among Family Caregivers of Individuals With Schizophrenia or Bipolar Disorder

A cross-sectional descriptive correlation study was performed to investigate the risk of posttraumatic stress disorder (PTSD) among 300 family caregivers of individuals with schizophrenia or bipolar disorder and examine the relationship between perceived social support and risk of PTSD. The Arabic version of the PTSD Checklist for DSM-5 (APCL-5) was used to investigate risk of PTSD; the Arabic version of the Multidimensional Scale of Perceived Social Support was used to measure perceived social support. Mean score of the APCL-5 was 46.1, indicating risk of PTSD among family caregivers. A negative moderate correlation was found between risk of PTSD and perceived social support. The caring process is demanding and highly stressful, putting family caregivers at risk for PTSD. Social support is crucial in decreasing this risk. [Journal of Psychosocial Nursing and Mental Health Services, 57(8), 37-43.].

The last taboo: The experience of violence in first-episode psychosis caregiving relationships

OBJECTIVES

Informal caregiving relationships play an important role in facilitating recovery outcomes in psychosis. The relationship can serve as a source of positive experiences that co-exist alongside common challenges typically associated with mental health problems. People with psychosis, when compared to the general population, are more likely to perpetrate acts of violence, a relationship that is particularly evident during the first psychosis episode. Although victims of service user violence are typically people already known to them, such as informal carers, there remains a lack of understanding about their caring experiences and needs. This study sought to address gaps in the literature by exploring the subjective accounts of informal carers supporting a relative experiencing their first episode of psychosis who has also behaved violently towards them.

DESIGN

A cross-sectional design was employed.

METHODS

Individual semi-structured interviews, which were audio recorded and later transcribed for analyses, were undertaken with a convenience sample of eight carers drawn from a specialist early psychosis service. Interview questions focused on their experiences of patient violence, the subjective impact, and coping strategies. An interpretative phenomenological approach was used to analyse the data.

RESULTS

Participants were mostly living with their relative with psychosis and were typically female, parents, and from a black and minority ethnic background. Data analyses identified seven key themes from participant interviews including the lack of predictability over when the violence occurred, being scared and fearful, keeping quiet about what happens at home and in the caregiving relationship, and staying safe.

CONCLUSIONS

Reports by informal carers about experiencing violence and victimization from their relatives with psychosis are an important issue in some caregiving relationships during the first episode. Developing a more informed understanding of the specific needs of these carers and the caregiving relationship is indicated. The implications for service providers are discussed.

PRACTITIONER POINTS

Carers were exposed to a broad range of patient violence, which included being kicked and having weapons used against them. The violence typically occurred within carers' homes, when no other people were around. Patient violence impacted negatively on carer emotional and physical functioning, which included leaving carers living in fear of their own safety and what might become of their relative. The results highlight the importance of routinely asking first-episode carers about their experience of patient violence. The development of interventions (e.g., identification of early triggers, de-escalation) that are able to take account of the ongoing nature and complexity of the caregiving relationship but are purposefully aimed at supporting carers to remain safe in their relationship should be explored for their impact.

Informal Caregiving Relationships in Psychosis: Reviewing the Impact of Patient Violence on Caregivers

A modest association can be found between people with a schizophrenia spectrum diagnosis (psychosis) and perpetrating acts of violence. When a person with psychosis does engage in violence, it is their informal carers, when compared to those from the general population, who are more likely to be the targets, and violence will often occur within the family home. Despite the importance of carer support for improving patient outcomes, our understanding of how carers are impacted by patient initiated violence in psychosis remains limited. This paper reviews literature documenting the effects of patient-initiated violence in psychosis on carer functioning. The review comprised searches of Medline, PsychInfo, Embase, and Web of Science databases and the hand searches of reference lists from relevant published papers. The review was limited to English language publications from inception to 11th September 2017, and where carer experiences following reports of violence from patients with psychosis were specifically recorded. Data from 20 papers using mixed methodologies were reviewed. Patient violence in psychosis was linked to poorer carer outcomes, including carer reports of burden, trauma, fear, and helplessness. There is, however, a significant need for further studies to systematically quantify the impact and correlates of patient initiated violence on psychosis caregivers, and improve prevention.

Safety Fears Held by Caregivers about Relatives with Psychiatric Disorders

In this period of post-deinstitutionalization, much of the care for people with severe psychiatric disorders (PD) is provided by their families. A primary stressor for caregivers is fears regarding their own safety and that of others, which has been virtually unexplored. To fill this gap, factors in three domains were assessed: (1) relatives with PD, (2) family caregivers, and (3) interactions with each other. This investigation was a secondary analysis of data obtained from a national survey of caregivers of adults with mental illness conducted by the National Alliance for Caregiving. A subsample of 1,505 was used in the present study. Fear of harm was positively associated with the following factors: relatives with PD-serious mental health problem, alcohol and substance abuse, receipt of crisis mental health treatment, history of arrest; interaction-greater difficulty getting relative to take medications as prescribed; and fear that relative would be hurt by others or die by suicide. Social workers need to be cognizant of risk of potential violence against caregivers and ensure the safety of these family members, even if they may not be their primary clients. The article includes recommendations for family inclusion in the treatment of people with PD.

The coping process of Japanese parents who experience violence from adult children with schizophrenia

With the acceleration of deinstitutionalization might increase families' chances of suffering violence by patients. This study clarified parents' coping processes with violence experienced from patients with schizophrenia. The grounded theory approach was used, and 26 parents were interviewed. We identified a four-stage coping process: (1) hope for treatment, (2) living with violence, (3) trying to solve violence, and (4) last solution for violence. This coping process had two illness-related characteristics: (1) a process of coping with two main stressful events (the illness and violence), and (2) the need for long-term appraisal of violence because of its unclear causes.

Factors associated with family violence by persons with psychiatric disorders

Family violence by persons with psychiatric disorders (PD) is a highly under-researched area. The primary objective of the present analysis was to identify perpetrator, victim, and interaction/relationship factors associated with this phenomenon. The secondary objective was to examine the extent to which the relationship between caregiving and family violence was mediated by limit-setting practices used towards relatives with PD. 573 adults across the U.S. with an adult relative with PD completed an online survey. Multivariate logistic regression was performed examining the association of factors with the occurrence of family violence. Mediation was assessed with Sobel testing. Family violence was significantly associated with the following factors: perpetrator-income, illegal drug use, psychiatric hospitalization, treatment attendance, and use of medications; victim-age, employment status, income, and mental health status; interaction/relationship-parental relationship, co-residence, use of limit-setting practices, representative payeeship, and unofficial money management. Mediation was statistically significant. Increasing access to mental health and/or substance abuse treatment may decrease the risk of family violence. Interventions may benefit from attempting to decrease/modify the use of limit-setting practices. Where family representative payeeship or unofficial money management exists, it is advisable for practitioners to assess and address financial coercion and promote greater collaboration in financial decision-making.
