Summary
This summary is machine-generated.Measurement equivalence of intimate partner violence (IPV) perpetration tools is crucial for accurate intervention trials in LMICs. Findings reveal inconsistencies, necessitating refined measures for reliable prevention research.
Area Of Science
- Global Health
- Psychometrics
- Violence Prevention
Background
- Studies on intimate partner violence (IPV) interventions in lower- and middle-income countries (LMICs) are increasing.
- However, the measurement equivalence of IPV perpetration constructs has not been established in these contexts.
- This study assesses the measurement equivalence of physical and sexual IPV perpetration measures in LMIC trials.
Purpose Of The Study
- To evaluate the measurement equivalence of physical and sexual IPV perpetration measures across intervention arms and over time in LMIC trials.
- To determine the impact of measurement non-invariance on the inference of intervention effectiveness.
- To provide recommendations for improving measurement practices in future IPV prevention research.
Main Methods
- Utilized data from three intervention trials involving men in LMICs (N=505-1537).
- Employed tetrachoric correlations and multiple-group confirmatory factor analysis (CFA) to assess measurement invariance.
- Examined treatment effects using covariate adjustment and inverse probability of treatment weighting (IPTW).
Main Results
- High average item correlations were observed, increasing over time, particularly in intervention arms for physical IPV.
- Longitudinal measurement non-invariance was detected in intervention arms in two of the three studies.
- A correlated two-factor solution generally provided the best model fit; one study achieved invariance, while another did not.
Conclusions
- Current measures of physical and sexual IPV perpetration may not support valid effect estimation without refinement.
- Future intervention trials require expanded item sets, content validity assessments, and rigorous measurement invariance testing.
- Consistent use of validated item sets is essential for accurate inference on IPV prevention intervention effectiveness.

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
Selection Bias: This occurs when the study population is not...
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. To illustrate this concept, consider a kitchen...
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
