BackgroundsDV issue got attention since 1980s in TaiwanThe Deng murder case in 1993 DV became a rising public policy issue in Taiwan since 1990sThe Domestic Violence Prevention and Control Act (DVPCA) put into effect on June 24th 1999 Domestic violence incidents are mandatory reported to local authorities ( Domestic Violence and Sexual Assault Prevention Center, DVSAC) according to the DVPCA.

From 2002 to 2010, the IPV (Intimate PartnerI Violence) incidents reported to authorities increased 112%*

Why need Danger Assessment?Assist police officers, social workers, and health service providers to determine which IPV cases need the most immediate attention and extensive intervention because the demand for domestic violence services far exceeds supply.Strategies need to be tailored to the level of dangerousness in the violent relationship in order to reduce further disrupting the lives of IPV survivors and their children.

Purpose of this ResearchThe TIPVDA (Taiwan Intimate Partner Violence Danger Assessment) is an instrument designed to assess the likelihood of lethality or near lethality occurring in a case of intimate partner violence. This article describes the development, psychometric validation, and suggestions for use for the TIPVDA.*

Survey SampleAll the IPV victims sample (n=773) divided into 2 sub-sample randomly Analytical samplefor developing n=54470.3 Validating samplefor validation n=22929.7

Analysis Identify samples abused situation, then compare the lethality and non-lethality groupsidentity the most important risk factors by logistic regression models.Decide the clear cut point by analysis PPV, NPV, sensitivity and specificity.

ConclusionThe empirical results suggest that the TIPVDA was administered reliably, and they provide significant evidence of the concurrent, discriminate, and criterion-related validity of this instrument.*

TIPVDA in PracticeAll the police departments, DVSAC, victims advocacy organizations and hospitals are using TIPVDA to assess the IPV victims danger in Taiwan.Now all the IPV incidents reported to local authorities are required to fill up the TIPVDA. The Safety Nets- a multi-agency risk assessment conference- occur monthly and provide a forum for sharing information and taking actions to reduce future harm to high-risk victims and their children in each city and county in Taiwan.

*

Impacts of using TIPVDAIncrease the workers sensitivity on assessing victims danger.Improve the cases reporting accuracy.Establishing the platform for all the workers of criminal justice , social service, and health care systems within community networks to discuss the victims situation promptly.And the most important, increase the victims safety.

*

Research limitationsCould not follow the sample for a periods of time to survey againCannot examine the predictive validity.
