In a longitudinal study investigating the impact on domestic violence victims in South Africa, non-probability sampling methods are often employed to ensure that the participants specifically represent the population of interest. Among the sampling methods listed, two particularly stand out for this type of study: **Purposive/Judgemental Sampling** and **Snowball Sampling**.
1. **Purposive/Judgemental Sampling**: This method is appropriate when researchers seek specific individuals who meet certain criteria (in this case, victims of domestic violence). It allows for the selection of a focused and relevant sample that can provide deep insights into the experiences of those affected by domestic violence.
2. **Snowball Sampling**: This technique is also commonly used in studies where the population is hard to reach or be identified, such as victims of domestic violence. Existing participants can refer researchers to other individuals who meet the study's criteria, helping to build a sample from a network of participants who may not be easily accessible through other means.
Both methods can be effective in understanding the complexities surrounding domestic violence victims. However, the choice between them may depend on specific study goals and contexts.
**Conclusion**: Given the nature of the study and the challenges in accessing the target population, both Purposive/Judgemental Sampling and Snowball Sampling are the most suitable non-probability sampling methods for this longitudinal study.
