Summary
This study evaluated a Sexual Assault Nurse Examiner (SANE) program using mixed methods. The SANE program successfully improved legal systems change for sexual assault survivors.
Area of Science:
- Social Sciences
- Public Health
- Health Services Research
Background:
- Mixed methods research is increasingly used in program evaluation.
- Understanding the effectiveness of community-based interventions requires robust research designs.
- Sequential explanatory mixed methods designs offer a framework for integrating quantitative and qualitative data.
Purpose of the Study:
- To review epistemological and design issues in mixed methods research.
- To evaluate a community-based intervention using a sequential explanatory mixed methods design.
- To examine the impact of a Sexual Assault Nurse Examiner (SANE) program on postassault care and prosecution rates.
Main Methods:
- A sequential explanatory mixed methods design was employed.
- Quantitative data were collected to assess changes in prosecution rates.
- Qualitative data were gathered to explore the mechanisms of intervention effectiveness.
Main Results:
- The Sexual Assault Nurse Examiner (SANE) program was successful in achieving legal systems change.
- Quantitative findings indicated a positive impact on prosecution rates.
- Qualitative data illuminated the mediating factors contributing to the intervention's success.
Conclusions:
- Sequential explanatory mixed methods designs can effectively evaluate complex interventions.
- The SANE program demonstrated effectiveness in improving postassault care and legal outcomes.
- Challenges in blending methodologies require careful consideration in mixed methods research.

01:30Community Based Intervention
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

01:20Comparing the Survival Analysis of Two or More Groups
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and Cox...
01:19Methods to Assess Microbial Communities
Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...
01:25Strategies for Assessing and Addressing Confounding
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

01:20Study Designs in Epidemiology
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.

02:40The Scientific Method
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
