Effectiveness of ICT-based intimate partner violence interventions: a systematic review

Abstract

Background

Intimate Partner Violence is a “global pandemic”. Meanwhile, information and communication technologies (ICT), such as the internet, mobile phones, and smartphones, are spreading worldwide, including in low- and middle-income countries. We reviewed the available evidence on the use of ICT-based interventions to address intimate partner violence (IPV), evaluating the effectiveness, acceptability, and suitability of ICT for addressing different aspects of the problem (e.g., awareness, screening, prevention, treatment, mental health).

Methods

We conducted a systematic review, following PRISMA guidelines, using the following databases: PubMed, PsycINFO, and Web of Science. Key search terms included women, violence, domestic violence, intimate partner violence, information, communication technology, ICT, technology, email, mobile, phone, digital, ehealth, web, computer, online, and computerized. Only articles written in English were included.

Results

Twenty-five studies addressing screening and disclosure, IPV prevention, ICT suitability, support and women’s mental health were identified. The evidence reviewed suggests that ICT-based interventions were effective mainly in screening, disclosure, and prevention. However, there is a lack of homogeneity among the studies’ outcome measurements and the sample sizes, the control groups used (if any), the type of interventions, and the study recruitment space. Questions addressing safety, equity, and the unintended consequences of the use of ICT in IPV programming are virtually non-existent.

Conclusions

There is a clear need to develop women-centered ICT design when programming for IPV. Our study showed only one study that formally addressed software usability. The need for more research to address safety, equity, and the unintended consequences of the use of ICT in IPV programming is paramount. Studies addressing long term effects are also needed.

Background

Intimate partner violence includes physical violence, sexual violence, stalking, and psychological harm inflicted by a current or former partner or spouse [1]. Violence against women (VAW) has been described as a “global pandemic” by the United Nations [2]. It is considered both a violation of women’s human rights [3] and a public health issue [4]. In low- and middle-income countries, violence against women is widespread and often involves pregnant women [5, 6]. However, violence against women occurs in high-income countries as well [7, 8]. Nearly one in three women have experienced intimate partner violence or sexual violence [9]; therefore, it is important to disseminate as widely as possible the knowledge and tools related to IPV prevention and to intervention to empower the women subjected to IPV. Information and communication technologies (ICT) present an opportunity for such dissemination. ICT are being adopted at unprecedented rates in high-income as well as low- and middle-income countries [10]. Moreover, the use of the internet [11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37], mobile phones, and smartphones [36, 38,39,40,41,42,43] for health purposes has been well documented in research. It has been used to address chronic disease management [44, 45], mental health challenges [46, 47], and hospital readmissions [48], encompassing applications that target the public (i.e., public health informatics), interactions between patients and healthcare professionals, and applications for individual use through smartphone apps (i.e., consumer health informatics). However, little is known about the use of ICTs in the context of violence against women, and only a few articles on the subject have been published recently [43, 49, 50]. At the same time, there is a solid increase in phone ownership and access to the internet in low- and-middle-income countries [51], which suggests the possibility of implementing ICT-based interventions to address IPV in these countries.

Recent systematic reviews showed that the efficacy of ICT-based mobile apps for health (mHealth) is still limited, as research in the field lacks long-term studies and existing evidences of impact are inconsistent [52]. Also, mHealth in the domain of violence against women (VAW) showed an abundance of apps addressing one-time emergency or avoidance solutions, and a paucity of preventative apps, which indicates the need for studies addressing data security, personal safety, and efficacy of interventions using apps to address VAW [53]. By extension, investigating the situation of ICT in IPV seems a necessary step.

Given the existing IPV interventions challenges, the evidence demonstrating effectiveness of online interventions in health, the rise of research on online IPV interventions, the risks inherent in ICT use for IPV programming, it is important to synthesize the available evidence regarding the use of ICT-Based IPV interventions. To our knowledge, there is no systematic review of such work. To address this knowledge gap, we initiated a systematic review of literature on ICT-Based IPV interventions. The study objectives were to examine whether ICT could become acceptable for effective IPV interventions, we reviewed the literature on the use of ICT-based interventions to address IPV issues. The questions that guided us in examining the were as follows: (1) “what type of objectives did ICT based interventions tried to address?”, (2) “were ICT based interventions effective in addressing IPV?”, and (3) “what type of strategies did they implement to mitigate ICT risks (e.g. safety, data security)”. The results will inform future ICT-based IPV interventions.

Methods

A systematic review was conducted, employing a digital search of bibliographic databases: PubMed, PsycINFO, and Web of Science. The literature was systematically screened by titles and abstracts and by applying key search terms. The following search terms were used: women, violence, domestic violence, intimate partner violence, information, communication technology, ICT, technology, email, mobile, phone, digital, ehealth, web, computer, online, and computerized. The full list of search terms is provided in Table 3 (See Appendix). Studies were included if they described an intervention that used some form of ICT, and if the recipients were women who experienced intimate partner violence or domestic violence, no matter what was the intervention type, comparison group, outcomes, study design, who was providing the intervention. We excluded studies that did not focus on ICT, studies where interventions were not aimed at women with IPV experiences, studies that described protocols, were not written in English, or were not full text, as well as journal articles and chapters in books. Non-English-language articles were excluded because no evidence exists of systematic bias caused by language restrictions [54]. The literature search was not subjected to any time limitations. The most recent search was completed on June 30, 2020.

The literature search, review, and data collection from articles was conducted by a single individual and was repeated by one other individual, the two resulting articles were then integrated. A meta-analysis was not conducted because of the disparities in study design, variables, and exposures between the studies.

Results

Summary

In total, 259 articles were identified, among which 105 articles were duplicates. Out of the 154 unique articles, 125 were excluded based on the content of their abstracts. The inclusion criteria were then applied to the remaining 33 articles after reading their full text. Four articles were then excluded, and 25 articles were kept for analysis [9, 55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78] (Fig. 1).

Table 4 (see Appendix) lays out the studies in terms of population, intervention, comparison groups, and outcomes (PICO). Table 1 presents the authors, publication year, study country, study type, recruitment space, theme, outcomes, sample size, sample size per arm, control group, and the type of ICT Used for the 25 studies. Out of the 25, 23 (92%) took place in North America (20 studies (80%) in the United States and 3 (12%) in Canada), 1 study (4%) took place in Australia, and 1 (4%) in New Zealand.

Table 1 Summary of the 25 studies

Most studies focused on women with potential vulnerability to, past experience of, and/or current experience of intimate partner violence, with the exception of one [74], which included both men and women as study participants. Four studies included women who were pregnant [56, 58, 69, 72]; two of these studies included women up to 3 months postpartum who had history of IPV [56, 72]. Two studies focused on women with a history of IPV and who were active substance(s) users [59, 65], and 1 study on women who were at risk of HIV through unprotected intercourse [65].

Out of the 25, 17 studies (68%) were solely desktop- or laptop-based [9, 55, 57, 58, 60, 61, 63, 65,66,67, 69, 70, 72,73,74, 76,77,78], 2 studies (8%) were solely tablet-based [56, 62], 1 study (4%) used computer and telephone [77], 1 study (4%) used tablet and telephone [59], 1 (4%) implemented a kiosk system [75] and 3 (12%) were not reported and supposed any type of ICT [64, 68, 71].

Studies’ designs and interventions

Table 2 shows the characteristics of the included studies. The 25 studies included 16 randomized controlled trials (12 two-arm and four three-arm studies), four pre-post designs, two cross-sectional studies, two prospective studies, and one diagnostic case-control study (i.e. retrospective data with known disease-positive and disease-negative cases [79]).

Table 2 Characteristics of the included studies

Control groups varied widely, and wait-list controls were used in five RCT studies [55, 69, 73, 74, 78]. Four studies allowed control groups to access websites with static, or non-interactive, or non-tailored content [9, 57, 64, 68], while two studies used irrelevant information for control groups [59, 61], seven control groups used face-to-face (or paper-based self-reported) screening [56, 60, 62, 65, 70, 71, 75], four had the intervention group play the role of control (i.e. pre-post design) [58, 63, 66, 67], and three studies had no control groups [72, 76, 77]. The sample size in the RCT studies varied extensively from 32 participants to a high of 2416.

The 25 interventions implemented had various foci. ICT was used for screening and disclosure in 13 (52%) of the studies. Five studies (20%) aimed at IPV prevention, four (16%) studies used ICT to address the mental health of female victims of IPV, and two (8%) studies used ICT to provide support for decision aid. Only one (4%) study assessed mainly the suitability of ICT for use in an IPV context.

The 25 studies had five types of interventions and varied study settings. In terms of settings, 14 studies were conducted in medical services facilities [55, 58, 62, 63, 67, 69,70,71,72,73,74,75,76, 78] such as emergency departments, clinics, community health centers, trauma treatment centers, and family practices. Six studies were conducted in the community [9, 56, 57, 61, 64, 68], four in social services facilities [59, 60, 66, 77], and one in legal services facilities [65].

The 25 studies represent a range of uses of ICT in the context of IPV, addressing screening and disclosure, IPV prevention, ICT suitability, empowerment and support, and women’s health.

Screening and disclosure

In three studies, IPV screening using ICT was found to be as effective as using the usual face-to-face/paper method [58, 70, 71]. One study reported that computerized screening was more sensitive and less or similarly specific compared to face-to-face staff screening [71]. One study reported high self-disclosure of IPV using computers vs in person IPV screening with health professionals; out of 250 female patients who participated in both screening methods. 67(27%) patients out of the 250 disclosed some form of IPV in person compared to 85 (34%) who disclosed IPV via a computer. Out of those 85 patients, 60 (71%) also disclosed IPV to their doctors in person and 24 patients (26%) disclosed via a computerized tool but not with the doctor [58].

One study that included African American women in a women, infants, and children (WIC) services setting found that women were less likely to disclose IPV using a computerized intervention than in person [62]. A study that used a tablet for disclosure during perinatal home visitation found the tablet to be a conduit through which interpersonal connection between women and home visitors was facilitated [56]. One study found that women were more likely to disclose IPV using ICT, leading to higher rates of screening and disclosure [78]. One study reported that 81.8% of women disclosed using the ICT intervention, and only 16.7% women disclosed using usual care [69]. Another study found that implementing ICT-based disclosure in an emergency department was successful and reliable [75].

IPV prevention

Two studies addressed IPV prevention [57, 65]. One study showed that 62% of the participating women who used ICT were less likely to report experiencing physical IPV at a follow-up (12 months later), 76% were less likely to report IPV with injury, and 78% were less likely to report severe sexual IPV [65]. The study by Braithwaite et al., which targeted both males and females using ICT, reported less physical aggression committed by females at post-intervention, as well as less physical aggression committed by both males and females at a 1-year follow up; also, the study showed a large reduction in expected counts for female- and male-perpetrated physical aggression at the 1-year follow-up (71 and 99%, respectively) [57].

Women’s health

Our systematic review showed that ICT has been used to address two aspects in the lives of some women experiencing IPV: substance use and mental health. Six studies used online tools to address the mental health of women experiencing IPV [9, 55, 60, 63, 67, 77]. Depression was measured in five studies [9, 55, 60, 63, 67], anxiety was measured in three [60, 63, 77] and stress in two [63, 67, 77]. In all studies, mental health showed improvement compared to intervention. One study reported that women found it easier and safer to report drug use and partner abuse through a computer than in person [77]. The study by Hassija et al. addressed the treatment of IPV-related trauma through video conferencing, and found the method effective at reducing post-traumatic stress disorder (PTSD) symptoms, with high users’ satisfaction [67].

Empowerment and support

ICT was used to empower women by enabling them to create safety and action plans and by providing them with tools for enhanced decision making and self-efficacy. Three studies focused on women creating a safety and/or action plan in the event of a future partner abuse incident [61, 66, 69], with two interventions providing additional local resources [61, 69]. In one study, 90% of the participating women who used ICT reported leaving their abusive partner within the year [66], and in another study 64% of the participating women reported the intention to make changes in regard to their IPV within 30 days to 6 months [69]. Moreover, in a single study focused on using online tools to teach participants about behaviours and/or actions related to safety [9], researchers reported a 12% significant increase in safety behaviours for the ICT-based intervention group, compared to a 9% increase for the control waitlist [9]. In addition, a study reported that participants found using a computer survey to disclose IPV safer than a face-to-face survey [55].

In terms of decision-making and self-efficacy, two studies reported that more than 78% of the participants acquired general skills through the ICT-based interventions [9], and two other studies reported that participants gained decision-making skills through the ICT-based interventions [61, 66]. Additionally, using their new skills, women experienced lower decisional conflicts and had an overall less difficult time deciding on their actions [61, 66].

ICT suitability

Only 1 study has a formal testing for the usability of ICT software as a major focus using the Systems Usability Scale [59]. The results indicate high satisfaction with the software usability.

Measurements

Table 5 (Appendix) summarizes the outcomes measured by each study. Our review revealed a wide variation among studies in terms of outcomes measured for studies that address the same focus. In total, 27 measurement tools were used in the 25 studies (see Table 5 in Appendix).

Among the 12 studies that address screening and disclosure, five studies used a simple disclosure count [55, 56, 69, 75, 78]. Two studies used non-validated questionnaires [58, 72], and two studies used the Partner Violence Screen (PVS) and the Abuse Assessment Screen (AAS) [73, 74]. Three studies had no common outcome measurement tools.

The four studies [63, 64, 67, 77] that focus on mental health used eight different outcome measurement tools; only the PTSD Checklist (PCL) was common to two studies [63, 67].

In terms of suitability of ICT, the Systems Usability Scale (SUS) was used in one study only to assess software usability [59].

Out of the five studies [9, 57, 62, 65, 70] focusing on IPV prevention, three studies [57, 62, 65] used the Revised Conflict Tactics Scale (CTS2). The two studies that addressed support [66, 68] had no common measurement tools.

Discussion

Principal findings

Our review revealed the emerging nature of ICT use in IPV research. While there is a growing interest in the use of ICT in IPV interventions, there are virtually no studies examining its challenges.

While most of the studies used ICT to enhance screening and increase the disclosure rate, few studies targeted IPV prevention and even fewer aimed at improving support. Suitability of ICT was seldom assessed in a formal way using a validated usability scale (e.g. Systems Usability Scale) or methodology [80].

In addition, while most of the studies used RCT design, the number of arms, the population, the control groups used, the sample sizes, and the outcome measures varied widely among the studies, which makes it hard to compare those results. With the exception of two large sample sizes that were used in two non-RCT studies (one that accessed electronic health records for an artificial intelligence application [76], and another that used the emergency department [75]), the sample sizes per arm were generally low. The sample size per arm was less than 30 in four studies. Only six studies had a sample size per arm between 100 and 300, and only four studies had a sample size per arm between 300 and 805. This suggests that the current ICT-based IPV interventions have limited generalizability and comparability—especially because only six studies were conducted in the community.

Twenty-three (92%) of the studies were conducted in North America, 20 (80%) of which were in the United States, which is an additional limitation to the generalizability of the findings since they lack diversity in terms of ethnicity, race, language, and cultural backgrounds. Diversity is crucial in IPV. Research shows that foreign-born immigrant as well as indigenous women are more likely to experience IPV [81, 82] and intimate partner homicide than other women [83, 84]; hence, addressing diversity in IPV is critical. It is encouraging that one recently published RCT protocol laid out a plan for culturally tailored intervention targeting immigrant, refugee, and indigenous survivors of IPV [85].

Equity

Technology is costly in terms of hardware, software and data plan costs. Consequently, while access to ICT by women experiencing IPV is a challenge in high income countries, including the United States [86, 87], it is even more difficult in low- and middle-income countries (LMICs). This creates inequity in access to technology, and a digital divide among women subject to IPV. This inequity challenge and its impact on outcomes has long been observed in electronic health (eHealth) [88, 89] and needs to be addressed in ICT-based IPV interventions; it was not addressed in the studies covered by our review. Also, involvement of users in software design is a well-known need that is effective in producing software that works for users and aligns with their priorities and is suitable for their environments [47, 90,91,92,93,94]. Hence, involving women experiencing IPV in the research team and in the ICT software design process is paramount to ensure usability and accessibility of the software and as a matter of equity [95]. There is a lack of research in this area in the studies covered by our review.

A recent study protocol is promising that ICT will ensure lower access barriers [96], which is the traditional unchecked point of view; this is another demonstration of the need to shed a critical light on the use of ICT for women experiencing IPV, analyzing equity as well as the safety and ethical challenges involved.

Safety and ethical challenges

Our review shows that 8 studies [55, 56, 59, 63, 64, 70, 72, 75] reported that women found ICT interventions suitable for IPV disclosure; three of those studies found it particularly suitable in terms of confidentiality, usefulness, and satisfaction [56, 63, 72]. Stigma is an important factor associated with intimate partner violence [97] limiting agency in help-seeking for IPV [98]; ICT seems to be a tool that provide an opportunity for women subject to IPV. With the exception of one in which participants preferred a face-to-face discussion [62], IPV disclosure through ICT was found to be most appropriate in most of the studies compared to face-to-face disclosure and was perceived as non-judgemental and more anonymous than face-to-face discussion, which facilitated more disclosure.

The increase in phone ownership and internet access in low- and middle-income countries [51], coupled with the ability to use ICT to target individuals through health informatics tools that targets individuals (i.e. consumer health informatics) [99] such as apps, makes ICT a flexible tool to address IPV in multiple languages, embedding different cultural cues, and overcoming the cultural stigma related to disclosing IPV from the convenience of a personal ICT device (e.g. cell phone, smart phone). Simple ICT tools such as cell phones are available in rural areas and proved to be successful tools in the health domain (e.g. chronic disease management) [100,101,102]. However, it is important to note that one challenge of ICT-based interventions is that only women with basic literacy and IT knowledge can benefit; also, some victims may not have access to ICT, and some abusers may restrict their partners’ access to ICT. Therefore, in addition to the traditional security considerations related to the use of ICT, such as maintenance of privacy [103] and confidentiality [99], there are ethical issues related to the unintended consequences of ICT [104, 105], including safety risks.

In the IPV domain, sharing cell/smart phones at home or with neighbors is a common practice [106, 107], which might increase the risk of IPV if the perpetrators notice that women are using these devices to address IPV [108]. The studies covered by this review were located in high income countries; there is little to no examination of the problem of access to ICT (i.e. cost), nor of the risks inherent in the use of ICT (e.g. sharing devices, ability to access browsing history) in addressing IPV programming in a variety of contexts. Ethical challenges related to the safety of women increase when women are sharing cell/smart phones with perpetrators; in such contexts special considerations should be taken care of, including “safety by design” [109].

Safety challenges involved in the use of ICT in health have recently attracted much attention [105, 110]. Moreover, recent reflections related to the ethical challenges of using web-based RCT show the need to equip participants with information about Internet safety [111]; likewise, identifying and managing safety risks within ICT-based IPV research remains a perspective to be explored. This raises ethical questions related to the use of ICT, for example in the case of referral embedded in the IPV programming, as was the case in three studies included in this review [55, 73, 78]. Poor quality services are well documented in low-resource and rural areas [112], so referring women to such services might have negative consequences for them. While this is not an ICT issue, ICT facilitates communication of information and has the potential to exacerbate current challenges. This is part of the well-known unintended consequences of the use of information technology in health [113,114,115].

Future directions

Of the 19 studies that explicitly mentioned their settings, 14 were in urban settings, only three were in urban and suburban areas, and two were in suburban settings, suggesting a need to test ICT use for IPV in rural settings [67, 77] and uncover any particularities compared to the urban context.

It is also worth noting that our systematic review has not included search terms regarding the user of ICT tools to address IPV for women with disabilities. However, in a quick assessment, when we searched in PubMed for research that addresses the use of ICT to address violence in the context of women with disabilities, our search revealed only two papers [116, 117]. The use of ICT to address IPV for this particular group of women is important to address in a separate study, as ICT accessibility may be challenging for women with certain types of disabilities, especially since there is evidence that IPV occurs at higher rates in this population compared to the general population [118,119,120,121,122,123], and that ICT can play a major role in empowering people with disabilities [124]. The use of ICT tools to address IPV for women with disabilities, and the accessibility of these tools, remains an important area for future studies.

Moreover, our review indicated that there is a paucity of research addressing ICT use for IPV prevention and IPV treatment. There is a clear need for more research on ICT-based interventions to prevent IPV and to address post-IPV challenges, such as mental illness and the integration and coordination of mental and social services (e.g., employment, housing), which has never been addressed in the reviewed literature. In this context, virtual communities may play an important role in integrating and coordinating mental health services and social services [125]. While the studies showed different aspects of ICT use for IPV, a more integrative approach can be taken if researchers approach IPV using a virtual community framework. A virtual community (VC) is defined as a community of individuals cooperating using online tools to attain an objective [126]. Health VCs have been used in healthcare to provide patients with education, health education, and remote support; that proved to be an enabling and empowering factor, which allowed patients to become active participants in managing their health conditions [127, 128]. Support was not provided solely by health professionals; instead, health VCs connected individuals with common experiences (e.g., similar health conditions), which enabled them to interact and mutually support each other [129]. Healthcare providers could provide validated evidence-based health information, coupled with strategies for effective chronic disease management [130,131,132]. Ample evidence exists demonstrating that virtual tools are effective and efficient for addressing health issues experienced by patients with various health conditions (chronic kidney disease, pulmonary hypertension, cancer) [126, 132,133,134]. There is also ample evidence that health VCs are effective in engaging individuals managing their own health condition [131, 132]. Moreover, VCs can be patient-centred, customizable to individual preferences, and responsive to individuals’ needs and values [135]. In terms of mental health, an important factor for women experiencing IPV, VCs provide a secure, private way for women to communicate privately and securely and to access information tailored to their situation in a personalized manner. This privacy facilitates access and assists in overcoming stigma, especially for women from visible minority groups [136]. VCs have a proven potential to engage participants [137]. There is ample evidence that health VCs are associated with positive mental and social benefits, such as reduced loneliness and increased emotional well-being, self-esteem, and self-empowerment [129, 138, 139]. It is important to explore an integrative approach to ICT-based intervention in IPV using VCs, especially since VCs enable a community dimension that facilitates mutual support and empowerment among its members (e.g., abused women).

ICT vs. paper

In a study that screened for IPV, while women preferred computerized over face-to-face disclosure, computerized screening did not increase prevalence, so ICT did not lead to increase in disclosure. Also, when women disclosed by answering paper-based questionnaires, the self-completed paper-based questionnaires had less missing data collected than both computer-based and face-to-face interviews [70], which shows the advantage of having for paper-based screening (i.e. less missing data).

Likewise, while ICT allowed considerably higher IPV detection, this did not always lead to charting for IPV or to a follow-up by treating physicians [74]; more research is needed to understand the factors, such as continuing medical education [140], that increase the chances of charting and follow-up. Detection is not enough.

We have noted above the lack of research regarding equity, safety, and the ethical challenges involved in the use of ICT, as well as the lack of culturally, ethically, and racially sensitive ICT programs. ICT might be able to support and enhance more traditional on-the-ground program delivery; however, ensuring that effective ICT-based interventions reach the most vulnerable in equitable, ethical, and safe ways remains a research agenda to be undertaken.

Current results suggest that face-to-face and paper-based approaches should not be discarded, and that the computer-based software design must be user-centred and must follow usability principles [141, 142].

Limitations

Limiting the search to English language is one of the limitations of this study. Another limitation was the difficulty to compare the results, since the tools used to measure the same outcome varied widely between the studies. Various questionnaires were used to detect IPV, assess decisional conflict, assess mental health challenges, assess treatment efficacy, and assess different primary and secondary outcomes. An illustrative example is the varied questionnaires that researchers used to measure IPV [55, 57, 60, 62, 65, 69, 73,74,75], which included the use of an artificial neural network to identify IPV automatically via analysis of the notes stored in the electronic health records [76]. Our review shows that there are limits for comparing the effectiveness of the interventions in terms of mental health (e.g., reduction in stress, anxiety, or depression levels), given the great variety of mental-health-related measurement tools that have been used.

Conclusion

The evidence reviewed suggests that ICT-based interventions have the potential to be effective in spreading awareness about and screening for IPV. ICT use show promise for reducing decisional conflict, improving knowledge and risk assessments, and motivating women to disclose, discuss, and leave their abusive relationships. However, there is lack of homogeneity among the studies’ outcome measurements, and the sample sizes, the control groups used (if any), the type of interventions and the study recruitment space.

The use of ICT-based interventions seems to be an attractive option for disseminating awareness and prevention information [143], due to the wide availability of ICT (including simple mobile phones) in both high-income and low- and middle-income countries. ICT may also present an opportunity to deliver culturally sensitive multilingual interventions using consumer health informatics. However, there is a clear need to develop women-centred ICT design when programming for IPV. Our study showed only one study that formally addressed software usability. Moreover, research directly addressing safety, equity, and ethical challenges in using ICT in IPV programming are virtually non-existent; the need to find answers to equity, and the unintended consequences of the use of ICT use for IPV programming is necessary. In this context, virtual communities may play an important role in providing a sense of community and in integrating and coordinating the services around women experiencing IPV. Future longitudinal follow-ups could help determine the long-term effects of the use of ICT in IPV programming.
