Abstract

Intimate partner violence is one of the most challenging and demanding problems that the criminal justice system has to face. Given the severe consequences of intimate partner violence, it is imperative that intervention from the criminal justice system, regarding perpetrators, be effective to prevent further victimization and recurrences. In Portugal, it is up to the state prosecutor to decide which cases will be subject to a social reintegration program as a pretrial diversion program. This study aims to explore the variables that might influence the state prosecutor’s decision-making process. We have examined 283 intimate partner violence cases in which provisional suspension of criminal proceedings was applied. The decision as to whether defendants should be referred for social reintegration program attendance (G1) or not (G2) was made by the state prosecutor. Differences between G1 and G2 were identified: the victim’s age, couple living in a current relationship, drug-addicted defendant, intimate partner violence child exposure. However, defendants’ unemployment and drug abuse were the only two variables identified as a determinant for state prosecutor decisions. We believe that the effectiveness of state prosecution decision-making would benefit from: (a) systematically taking into account all intimate partner violence risk factors; (b) an index or checklist detailing what science reveals useful in intimate partner violence offenders’ social reintegration; (c) rehabilitation solutions based on the needs of each offender instead of a “one-size-fits-all” approach.

Introduction

The severe consequences of intimate partner violence (IPV) for victims, families, and the community as a whole, are widely described in the literature [1, 2]. Particularly relevant, to deter this kind of violence, and avoid or reduce its serious outcomes, is the early detection and intervention, not only in legal terms but also from the therapeutic/rehabilitation and social reintegration perspectives.

If IPV is considered a pathology of the interaction between couples, the intervention needs to include the victim, as well as the alleged offender. However, the focus of the intervention, namely for therapy/rehabilitation, has mainly been the victim. This is fundamental but not enough to prevent revictimization (when a victim is repeatedly exposed to violent behavior by an intimate partner [3]). The intervention with offenders is fundamental despite being infrequent in most countries [4, 5]. This may be due to multiple factors, including not only the judicial decision-making process but also the defendant’s availability and motivation for the procedures (which is the cause of a significant number of drop-outs) [6, 7]. It was found that the severity of the injuries is associated with the offender’s tendency to repeat aggressions [8]. Therefore, the therapy/rehabilitation and social reintegration processes are particularly important, especially in these more severe cases.

Several studies suggest that prosecution and actual conviction in IPV cases rarely occur [912]. Only 14.9% of defendants in Portugal were prosecuted in 2020, with 2.4%of those convicted [45]–and 17.2% of those sentenced to jail [46]. Furthermore, convictions seem to be inefficient and ineffective towards reoffending and recidivism [8, 13, 14], besides the personal, social, and economic costs associated with the imprisonment system [13, 15].

Thus, crime prevention, namely tertiary prevention [1618], which includes Social Rehabilitation Programs (SRP), is imperative for offenders. It focuses on preventing revictimization and recidivism and avoids incarceration [16]. Strategies may include treatments (e.g., cognitive-behavioural therapy [19, 20], or substance abuse addiction therapy [21]), community-based programs [16, 22] or other suitable services [23, 24]. The interventions should always be guided by the principles of risk, need, and responsivity [25].

The Portuguese case

In Portugal, IPV is considered a domestic violence crime of public nature (article 152.° of the Portuguese Criminal Code). This means that from the moment the public prosecutor’s office suspects a possible case, an inquiry is opened (article 263.° of the Criminal Procedure Code). The investigation is carried out by the state prosecutor who leads the inquiry. After gathering evidence, they will decide on the case filing, whether to proceed with the indictment or the provisional suspension of criminal proceedings (PSCP) with the application of alternative measures. The state prosecutor will proceed with the indictment if the defendant does not consent to the PSCP’s implementation (Fig 1).

The PSCP is used as an integrated consensual solution between the involved parties, targeting the defendant’s resocialization and the prevention of revictimization [26]. After PSCP implementation, the defendant must accept a set of injunctions or rules of conduct for a maximum period of 5 years. Twelve injunctions exist, according to article 281.° of the Criminal Procedure Code, namely the attendance of certain programs or activities, where the SRP are included. If the defendant complies, the case is dismissed pending the investigative judge’s agreement. Between 2013 and 2018, PSCP increased in Portugal by 60% [27]. However, its implementation in IPV cases is low (17%) [26].

The official Portuguese SRP is named Program for Domestic Violence Offenders (PAVD), designed to address only male defendants/convicted of IPV with a current or past relationship with a female victim [28]. The PAVD is executed by the Directorate-General for Reintegration and Prison Services (DGRPS), whose mission is to develop policies on criminal prevention, supervising the compliance of criminal measures decreed by the CJS, targeting the defendant´s social reintegration. PAVD aims to promote the perpetrators’ awareness and assumption of responsibility for their violent behaviour, as well as the use of alternative strategies to reduce reoffences and recidivism [28, 29]. This program uses a psychoeducational group intervention delivered in 20 sessions, in which several structural relational issues associated with IPV are addressed. It has a minimum duration of 18 months and requires the defendant to abide by the imposed rules and measures, which must be verified. It can be court-mandated as an accessory penalty or as a result of the PSCP agreement. It is also used, mandatorily, as an accessory penalty to offenders convicted to a prison sentence. PAVD has been tested and presents positive results [30]. DGRSP may also decide to send offenders for SRP implemented by non-governmental organizations [3133]. Offenders are free to apply and attend these programs voluntarily.

In Portugal, not all PSCP cases get referred to SRP. The referral is decided by the state prosecutor on a case-by-case basis according to their own criteria [34]. However, the literature indicates that to decide whether a specific IPV defendant is to be recommended for this type of program, a holistic assessment of both offender and victim should be performed, taking into account [3538]: age, education level, employment status, interpersonal relationship, type of inflicted violence, and substance abuse.

The literature in Portugal on the state prosecutor decision-making process regarding SRP implementation is almost nil [34]. Thus, drawing on the theoretical background outlined above, the current study aims to identify variables that may influence state prosecutor decision-making regarding the submission of defendants for SRP by the DGRSP.

Materials and methods

Data were obtained from Porto County District Prosecutor’s Office database, selected according to a non-randomized convenience sampling process, between 1st May 2019 and 1st January 2020 (Fig 2), following previous studies on these cases [8, 26].

Data were obtained through IPV police reports and filled in by information provided by the parties involved. The inclusion criteria of these previous studies were: (a) IPV case (between former or current intimate partners, dating, married or analogous, regardless of cohabitation); (b) victim: female aged 16 or older; (c) defendant: male, aged 16 (minimum age for criminal liability) or older; (d) cases in which PSCP was applied.

In the current study, a retrospective cohort design was used, focusing on those where PSCP was implemented. The data collection further encompassed a crosscheck of the DGRSP database, with a list of male defendants who accepted the PSCP application as well as the injunctions and rules of conduct decreed by judicial authorities (e.g. order the defendat to avoid all personal contact with the victim; Order the defendat to move out of and/or stay away from the victim´s home, business, school or other locations; order the defendat to stop all harassing, threatening and violent behavior; order the defendat to attend specific programs or activities). In case the defendant abides by such rules, proceedings shall be dismissed; if not, they shall continue to Trial.

IPV cases were selected concerning the period between January 1, 2010, and December 31, 2013 (n = 1.662). These cases were subsequently cross analyzed with the Public Prosecution Service’s IPV database, to check whether the selected cases had undergone PSCP. Two groups were then created, considering this last feature: G1 –With PSCP (n = 283); G2 –Without PSCP (n = 1.379). From the 1662 IPV cases, 283 were chosen in which the defendant agreed to the PSCP and, as a necessary consequence, the imposition of injunctions by the state prosecutor. This sample was then divided into two groups: G1, including cases sent to SRP by DGRPS (n = 199); G2, including cases with other types of injunctions (n = 84)–Fig 2.

A comparative study was then performed to identify differences between both groups (victims and defendants’ characterization, and violence-related variables), looking for a pattern of variables that may impact the state prosecutor’s decision-making process.

Statistical analysis was conducted using the R programming language R—version 4.0.5 [39]. In addition to the descriptive analysis, hypothesis testing for the association of characteristics with re-entry was carried out using Chi-Square. The pattern of missing data was assessed using Little’s Missing Completely at Random (MCAR) test using the LittleMCAR package [40]. The analysis was performed on imputed data using the Multivariate Imputation by Chained Equations (MICE) package [41]. Categorical variables were imputed using a proportional odds model and continuous variables using unconditional mean imputation. All variables presented were considered in the imputation model. Data imputation was repeated 100 times. To assess the reliability of the results, the same analysis was performed with the removal of incomplete cases relevant for each test. Significance was calculated to be p<0.05.

Access and permission to use the prosecutor administrative records database was granted by Porto County District Prosecutor’s Office. The study protocol was approved by the Ethics Committee for Health of Centro Hospitalar de São João / Faculty of Medicine, University of Porto, Porto. All guarantees of anonymity given were honored.

Results

The victims and defendants’ characterization are described in Table 1, and the relationship between the couple, as well as children´s exposure to violence, are described in Table 2. Victims average age was: (a) G1–44.06 years old (Min = 18, Max = 86; SD = 12.42); G2–41.37 years old (Min = 20, Max = 74; SD = 10.97). Defendant´s average age was: G1–47.12 years old (Min = 19, Max = 86; SD = 12.38); G2–44.29 years old (Min = 21, Max = 75; SD = 12.23). Significant statistical association was found regarding: victim’s age (χ2 = 18.81; p = 0.043); couple living in a current relationship (χ2 = 6.19; p = 0.045); drug addicted defendant (χ2 = 17.47; p = 0.002); IPV children exposure (χ2 = 9.75; p = 0.045).

The types of violence registered are described in Table 3. Physical and psychological abuse were the most frequent forms of violence in both groups, the latter being considered as such only when isolated. No significant statistical differences were found between groups.

The factors identified as determinants for DGRSP referral are described in Table 4. The defendant’s unemployment and drug abuse were the only variables with a significant statistical association with the state prosecutor’s referral of the defendant to DGRSP.

Discussion

The sociodemographic characteristics of victims and defendants in the study sample are similar to those of the original sample (n = 1662—Fig 2) [8, 26], before narrowing to PSCP cases only. These characteristics are also similar to those of other studies [35, 37, 4244].

Referral by CJS for SRP

Regarding IPV offenders, conviction rarely occurs [912]. In Portugal, in 2020, only 14.9% of the defendants were prosecuted and, of these, 2.4% were convicted [45]–and 17.2% serve a prison sentence [46]. This data is considerably lower when compared to other countries. For example, data from the United States and Canada has shown that 60% of IPV court cases result in conviction [47].

However, imprisonment has revealed to have little efficacy in revictimization and recidivism deterrence [8, 13, 14], not to mention other costs associated with the imprisonment process [13, 15].

Considering SRP, findings of several recent meta-analytic studies on its effectiveness on recurrence and recidivism with IPV offenders, point to a small-scale effect [4851]. However, SRP has shown encouraging results [36] compared to incarceration, although more evidence on their efficacy is required [48, 51]. This shortcoming may be due to the argument that one-size-fits-all treatment programs, as those used on IPV offenders, disregard differences in the interaction factors [52, 53]. Yet, it is noteworthy that, although small, this impact has proven significant in the lives of many victims [54, 55]. Overall, mandatory SRP with an intervention focused on social factors and challenging the defendant’s dysfunctional beliefs can be effective in reducing the likelihood of recidivism and protecting victims.

In the present study, considering the initial sample (n = 1662), only 11.9% of the individuals were assigned to attend SRP under DGRSP (n = 199). Yet, of those who were subject to PSCP implementation (n = 283; 17%), 70.3% were forwarded to SRP. Considering these figures, it poses as relevant to investigate which possible criteria are determining the state prosecutors’ decisions in these cases.

Determinants for SRP referral

Understanding which variables play a key role in the decision-making process of state prosecutors when referring a defendant to SRP is critical. Ideally, a holistic assessment of both offender and victim characteristics should be carried out [3538]. Yet, the literature points more commonly to factors related more specific to defendants, including [3537, 5658]: age; population affiliation; education level; employment status; personality characteristics; substance abuse history; criminal history; the number of prior IPV cases; type of inflicted violence; interpersonal relationship with the victim; children exposure to IPV. It imposes a reflection on each of these possible determinants:

  1. Age: Regarding the defendant’s age, no differences were found in the current study. However, other authors have suggested that older defendants are more likely to complete an SRP [59], and perhaps more open to welcoming alternative strategies to IPV deterrence [26], which could weigh on the CJS decision. On other hand, younger age is considered an individual and environmental risk factor for recidivism [60]. Considering the victim’s age, differences were found between groups (χ2 = 18.81, p = 0.043), however not exposing it as a determinant of the state prosecutor’s decision for SRP.
  2. Population affiliation: This was not considered in the present study since it was not available. Due to cultural characteristics, it may affect the effectiveness of the SRP efforts to change an offender’s behaviour [61], but it is insufficient for facilitators to adjust to the offenders’ culture [62]. The programs themselves must be adapted to these differences [37, 38, 63].
  3. Education level: This information was also not available in our data, despite its relevance. The offender’s education may be a predicting factor in determining who completes or drops out of treatment programs. Offenders who drop out of SRP demonstrated to have less education than those who completed the program [37, 44, 59, 64]. The offender’s ability to grasp the concepts in the SRP may lead to increased motivation, and more dedicated involvement in the working sessions [37, 44].
  4. Employment status: Our data analysis revealed that the likelihood of being referred to SRP was tripled in cases of unemployment as compared to employed defendants. Such a finding poses it as a determinant in the CJS decision-making (Table 4). This is aligned with research that found that a fourth to a third of individuals currently enrolled in SRP are unemployed [47]. Furthermore, unemployment and low income are considered as individual and environmental risk factors for recidivism and to predict IPV [60, 65, 66], as unemployment frequently generates problems within the couple [67]. Thus, it is expected that the state prosecutor may assume that an unemployed defendant would spend more time at home and therefore be more likely to commit new aggressions. Considering the victim, our results didn’t present any significant difference between groups. This may be because of the state prosecutor’s strong focus on the defendant profile. However, it is known that in cases of female victims, unemployment creates an economic dependency on the offender, a condition that may put the victim in a vulnerable situation being considered an IPV risk liability [66, 68, 69].
  5. Personality characteristics: These aspects were not studied, because in Portugal they are not typically collected by the CJS, mostly due to a data protection law that prohibits the presentation of ethnic data. However, literature reveals that the defendant’s personality characteristics may interact differently with the SRP [63] and can affect the effectiveness of the program’s efforts to change the offender´s behaviour [38]. Thus, this should always be considered to support the state prosecutor’s decision-making. Regardless, in Portugal, the offender’s psychosocial characteristics are always considered in the intervention by the DGRSP.
  6. Substance abuse: Regarding drug abuse, our results show differences between groups (χ2 = 17.47, p = 0.002), and revealed that defendants with a history of drug abuse are less likely than those without such a history to attend SRP (Table 4). Therefore, not being a drug user may be considered as a determinant for state prosecutor decisions. This may be explained by the necessity of sending the addicted defender to other programs for more suitable care, namely for substance abuse addiction therapy [7072]. However, regarding alcohol abuse, no differences between groups were found, perhaps because alcohol consumption is socially accepted in Portugal [73] and in certain cases, the difference between alcohol consumption and alcohol abuse is not so clear. Literature states that alcohol, like drug abuse, is considered an individual and environmental risk factor for recidivism and increases the number of occurrences and the severity of IPV events [43, 5658, 65]. Excessive alcohol consumption increases the risk of physical/psychological abuse by eight times and doubles the risk of intimate partner homicide (attempted or consummated murder). Thus, it seems that this factor should be taken into consideration by the state prosecutor.
  7. Criminal history: Criminal history was not included in the study from our initial research [26], because of the scarce number of cases that allowed us to obtain reliable results. Evidence from several studies found that IPV offenders had high rates of prior criminal history [74, 75], particularly in intimate partner homicide (IPH) cases [76]. The cases for weapon possession by the defendant were analyzed, verifying the inexistence of differences between groups and that it was not a determinant in mandatory SRP. However, weapon possession, namely firearms, among male partners with a history of IPV is a lethal risk factor for the IPH [77]. It doubles the risk of an intimate partner´s attempted or consummated murder [5658, 65, 76, 78]. Such an outcome may be dependent on the state prosecutor´s assessment of the risk levels in the case and consideration of applying other heavier, and hazard-adjusted legal measures.
  8. The number of prior IPV cases: This information was also unavailable for the study, despite its significance. While the tendency for violence to decrease after the alleged offenders’ first entry into the CJS, violence seems to be more severe and frequent in re-entries cases [8, 79]. Previous IPV cases are one of the most common risk factors of IPH [58, 76, 78, 80]. Considering “The best predictor of crime is prior criminal behaviour” [81], this factor should be always be considered in the CJS decision.
  9. Type of inflicted violence: The present study found no differences between groups, in this case, a factor which also does not appear to be a determinant for SPR attendance. It is conceivable that these results are due to the state prosecutor´s experience in previous cases devaluing the type of violence suffered by the victim [34]. However, attention should be given to the fact that certain types of IPV which are associated with IPH, may include harassment, physical violence, namely with strangulation, sexual violence, and child exposure to IPV [58, 77, 8284].
  10. Couple relationship: Differences were found between groups (χ2 = 6.19, p = 0.045) but this aspect did not show to be a determinant in the CSJ decision. However, literature states that separated couples, or those living apart, have a greater probability of being referred to SRP since this aspect is considered one of the strongest predictors of recidivism [24, 71, 85].
  11. Children exposure to IPV: Differences were found between groups (χ2 = 9.75, p = 0.045) but this aspect did not prove to be a determinant factor in the state prosecutor’s decision-making process. Nevertheless, the present study reveals a concerning number of children exposed to IPV (more than 53%). Exposure of children to violence between parents or caregivers is still a much-researched risk factor [8688]. This aspect must be taken into account, as it constitutes a form of serious violence against children, a risk factor for IPH, and prevention and rehabilitation of IPV cases need to include all involved family members [8891].

Study limitations and avenues for further reviews

The present results must be read with caution considering: (a) the low dimension of the sample; (b) data were obtained through IPV police reports and filled in by information provided by the parties involved; (c) data refers only to IPV crimes committed in the district of Porto, in the north of Portugal, and different outcomes may arise in other regions of this country or other countries; (d) some risk factors with dynamic characteristics (e.g. drug and alcohol consumption; couple relationship status; employment status) may have changed during the time of the data collection (police report) and the decision on whether to refer the case to SRP; (e) some important factors, mentioned above, were not studied due to lack of information or lack of a sufficient number of cases for this purpose.

Further studies should consider: (a) larger samples; (b) other samples, such as women perpetrators, different ethnic groups, and the LGBTIQ+ population; (c) a qualitative approach by interviewing state prosecutors, which may provide a wider content analysis of their decision-making process and allow for a better understanding of what underlies such decisions regarding which cases should be referred to SRP.

Conclusions

This study allows the following main conclusions to be drawn:

  1. There were differences between groups regarding the following: victim’s age; couple living in a current relationship; drug-addicted defendant; IPV child exposure;
  2. Unemployment and drug abuse showed to be determinant variables for state prosecutor decisions, regarding defendant referral to SRP attendance.

This study allows us to further consider that:

  1. The effectiveness of state prosecution services would benefit from systematically taking into account all IPV risk factors substantiated by scientific evidence, instead of leaving it as a burden on the decision-maker;
  2. This effectiveness would also increase if the reintegration solutions used were based on the needs of each individual, rather than a “one-size-fits-all” approach;
  3. The creation of an index or checklist based on what science reveals useful in IPV offenders’ reintegration might support the state prosecutor’s decision-making processes, as long as individuals involved are always looked at from an ecological approach. This Ecological Model [92, 93] has been adapted to explain social phenomena, in IPV cases, the risk for violence victimisation and violence perpetration. In the Ecological Model, personal, situational, and sociocultural factors are interpreted to understand how IPV may result from the interaction of factors at different levels of the social environment [94].
