Intervention Program With Perpetrators of Intimate Partner Violence

October 31, 2022 updated by: Olga Cunha, University of Minho
The current project aims to develop, implement and assess the effectiveness of an intervention program for perpetrators of intimate partner violence (both volunteers and court-mandated) that incorporates Motivational Interviewing techniques (MIT) as well as cognitive-behavioral and psychoeducational strategies implemented in a community setting. The intervention focuses on ending violence against the intimate partner and promoting the batterer's personal and social skills. The study uses pre- and post-treatment measures, with an experimental group (intervention) and two control groups (a group without intervention and a group without MIT). Data were collected at pre-test, post-test, and follow-up.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Group cognitive-behavioral intervention plus individual Motivational Interviewing
Group participants will participate in six individual sessions based on Motivational Interviewing techniques (60 minutes each) and then in 18 group sessions based on psychoeducational and cognitive-behavioral techniques (90 to 120 minutes each). Groups will be composed of 6 to 10 participants. The intervention will be delivered weekly.
Other: Psychological
EXPERIMENTAL: Group cognitive-behavioral intervention
Group participants will participate in 18 group sessions based on psychoeducational and cognitive-behavioral techniques (90 to 120 minutes each). Groups will be composed of 6 to 10 participants. The intervention will be delivered weekly.
Other: Psychological
NO_INTERVENTION: Treatment as usual (TAU)
Group participants will receive the usual treatment delivered by different institutions (e.g., correctional services, probation services, child protection services) as the participants of this study are justice-involved individuals (i.e., perpetrators of intimate partner violence).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Perpetration of abuse against intimate partner
Time Frame: 18 weeks
Marital Violence Inventory (IVC) - Total scores range between 0 and 40. Higher scores mean a higher frequency of intimate partner violence.
18 weeks
Attitudes towards intimate partner violence
Time Frame: 18 weeks
Attitudes towards Marital Violence Scale (ECVC) - Total score ranges between 25 and 125. Higher scores mean more supportive attitudes towards intimate partner violence.
18 weeks
Psychopathological symptoms
Time Frame: 18 weeks
Bref Symptom Inventory (BSI) - BSI includes nine dimensions and three global indexes. Higher scores mean more psychopathological symptoms.

Coping skills
Time Frame: 18 weeks
Coping scale - Total score ranges between 13 and 52. Higher scores mean better coping skills.
18 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Self-esteem
