Abstract:
In the forensic context, offenders often exaggerate psychosis symptoms to evade criminal responsibility. Nowadays, there are not many empirical studies on this topic in Thailand. The present study examines the evidence on this phenomenon. The objectives of this study were to determine the prevalence rate, examine the classification accuracy of the Thai version of the Symptom Validity Test (SVT-Th), and investigate the factors affecting the exaggeration of psychopathology symptoms among correctional inmates and mentally ill offenders (MIOs). The total number of participants was 608, including 528 prison inmates and 80 MIOs who were referred by the court to a psychiatric forensic department for a forensic psychiatric examination. The SVT-Th was examined to detect exaggeration of psychopathology symptoms.
introduction
Results of the SVT-Th using a cut-off score of ≥79 showed that the prevalence rate of feigned psychopathology was 8.88% among all forensic participants, of which 3.20% were correctional inmates and 46.30% were MIOs. According to the criterion of the SVT-Th, 90.50 % of respondents were correctly identified , while 6.10 % were incorrectly identified . Furthermore , this research found that offenders with a history of mental illness were statistically significantly more likely to exaggerate psychopathological symptoms than those without a history of mental illness . Regarding the type of crimes ( including violent crimes, sexual crimes, property crimes, and drug offenses ) and the number of crimes ( including first offenses, 2- to 3-time offenses, and more than 4-time offenses ) , there were no significant differences in the average SVT - Th score . Interestingly , individuals who had committed a violent crime and committed more than 4 crimes were likely to have more psychopathological symptoms than other groups .
In conclusions, the prevalence rate of feigned psychopathology in Thai forensic context is consistent with other studies. The SVT-Th demonstrated preeminent classification accuracy and has good psychometric properties for detection of exaggerating psychopath ology in Thai forensic samples. It is regularly acknowledged that people with psychological maladjustment (PMI) are over-spoken to in the criminal equity framework (see Munetz, Grande, and Chambers, 2001; Teplin, 1984). Of most prominent concern to emotional well-being experts working with wrongdoers with dysfunctional behavior (OMI), and aggravating the issue for remedial directors, are the discoveries that PMI have been detained at excessively expanding rates throughout the most recent ten years (eg, Condelli , Bradigan, and Holanchock, 1997; Hodgins, 1995; Steadman, Morris, and Dennis, 1995). Indeed, the United States has several times more people with serious psychological maladjustments in jail than in mental medical clinics (Abramsky and Fellner, 2003); in this manner, it shows up most of PMI are arriving in the criminal equity framework as opposed to the emotional wellness framework. It is broadly perceived that most gauges of the quantity of detained guilty parties experiencing psychological instability are under-delegate of real commonness rates (Rice and Harris, 1997), with late discoveries indicating around one-quarter (25%) of wrongdoers suffering from emotional well-being issues including a past filled with inpatient hospitalization and mental judgments (James and Glaze, 2006). The clinical picture in American correctional facilities is considerably all the more vexing (note that prisons detain people anticipating preliminary or sentenced for fewer genuine offenses), as neighborhood correctional facilities have supplanted psychological well-being offices as suppliers of emotional well-being treatment. As one model, in the mid-1990s, the Los Angeles County Jail framework outperformed state and private mental medical clinics to turn into the country's largest supplier of institutionally based emotional wellness administrations (Torrey, 1995). METHODS: With these movements in position of PMI, treatment efforts for OMI have not been able to stay up with the detainment rates in state and government prison and jail offices. Actually, the US remedial frameworks have been reprimanded for neglecting to give even negligibly fitting emotional wellness administrations for jail prisoners (Human Rights Watch, 2003). Intensifying the issue, the criminal equity framework was structured as an open wellbeing framework so it isn't astounding that couple of assets are focused towards the particular treatment needs of OMI (Boothby and Clements, 2000). Therefore, numerous OMI experiences expanded mental side effects (Morgan, Bauer, et al., 2010), with a lion's share requiring inpatient treatment for intense mental side effects during imprisonment (Lamb, Weinberger, Marsh, and Gross, 2007). At the point when administrations are justified, there remains a lack of experimental research managing successful treatment techniques for OMI. Truth be told, "treatment result look into on intellectually sick guilty parties explicitly is practically nonexistent" (Rice and Harris, 1997, p. 164), and "are as scant now as they were 30 years back… Too barely any projects are being created and… tried with the thoroughness that would yield the confirmation expected to mark them as proof based" (Snyder, 2007, p. 6). In this manner, rewarding OMI do as such without adequate viability or viability information on which to base their practices. Thus, doctors are left scanning for the best remedial treatment and rehabilitative techniques for detained OMI to lighten enduring (eg, improved emotional prosperity, diminished symptomatology, and so forth.) during times of imprisonment, and along these lines lessen mental (come back to the emergency clinic) and criminal (come back to the criminal equity framework with new charges or parole disavowal) recidivism when discharged go into society. The restorative treatment writing has basically centered around intercessions focusing on criminalness with non-disarranged guilty parties (see Andrews and Bonta, 2006; Gendreau, 1996 for surveys of this writing), and methodologies for rewarding criminalness as a rule populace detainees may likewise demonstrate useful for OMI whose criminal conduct has comparative etiology (Rice and Harris, 1997). In particular, OMI present with comparable criminal hazard factors as non-intellectually sick wrongdoers (Bonta, Law, and Hanson, 1998). There is persuading proof that remedial intercessions are better than endorsed approaches (eg, imprisonment, electronic observation, and so forth.) alone for decreasing recidivism (see Andrews and Bonta, 2006 for a careful survey).DISCUSSION
The best evidence-based treatment model for non-mentally disturbed offenders is the risk-need-response model (RNR; Andrews, Bonta, & Hoge, 1990). RNR is probably the most widely used model for assessing and treating offenders (Ward, Mesler, & Yates, 2007). In summary, R–N–R refers to identifying offender risk and adapting the treatment scope to the offender's risk of recidivism (higher risk requires greater and more intensive treatment; risk principle), identifying and rewarding variable (dynamic) risk factors directly linked to criminal behavior (criminogenic needs; needs principle), and finally providing psychological social treatments tailored to the offender's specific needs, such as the offender's learning style, motivation, personality or emotional mindset (responsiveness principle). In addition, treatments must be intensive in nature and last at least a few months (Gendreau, 1996), since increased treatment dose leads to lower recidivism rates (Bourgon and Armstrong, 2005; Wormith and Olver, 2002). Organized interventions produce more positive outcomes (Leak, 1980; Morgan & Flora, 2002), as does the use of homework assignments (Morgan & Flora, 2002) that help offenders reinforce information and expand understanding of the offenders' real world (Morgan, Kroner, & Mills, 2006). Regardless of the setting, professional teams that identify with offenders in relationship-oriented and helpful behaviors produce better outcomes (Andrews & Bonta, 2006; Skeem, Eno Louden, Polaschek, & Camp, 2007). In short, the best scientifically supported interventions for offender groups adhere extensively to the principles of RNR with an emotional social shell and are delivered by individuals with a stern but caring social style (Skeem, Polaschek, & Manchak, 2009).
