This Weeks Video Introduces You To The Hernandez Family Juan And Ele This week's video introduces you to the Hernandez family. Juan and Elena Hernandez are mandated to attend parenting classes. As part of the parenting classes, they are required to participate in both a pretest (taken before classes begin) and a posttest (taken after classes end). Pretests and posttests can yield very useful information. They can measure the learning that has or has not taken place as a result of the education being provided. For this discussion, imagine what kinds of questions would be on a pretest and posttest for this particular sample—parents attending parenting classes. The social workers designing these assessments likely aimed to measure parents' knowledge of child development, discipline strategies, communication skills, and parental confidence. Pretests would establish baseline knowledge and behaviors, while posttests would assess gains or changes attributable to the classes (Ebrahim et al., 2020). They probably included questions about effective discipline methods, understanding of child needs, and parental self-efficacy. Regarding attrition, the social workers might have considered the possibility that some parents would drop out before completing the program, which could bias the results. Attrition can threaten the internal validity of the evaluation if it is systematic—for instance, if parents with less motivation or certain demographic characteristics are more likely to withdraw (Goulson et al., 2019). To address this, they could have planned strategies such as follow-up contacts or incentives to minimize dropout and analyze whether attrition was random or related to specific factors. Lessons from attrition emphasize the importance of accounting for potential biases and maintaining participant engagement throughout the study. To evaluate the effectiveness of the parenting classes, I would recommend a quasi-experimental design employing measurement over time with a comparison group—either a matched control group or a waitlist control (Shadish et al., 2002). This design involves measuring participants' knowledge and behaviors at multiple points (pretest, posttest, and possibly follow-up). If feasible, including a control group that does not receive the intervention immediately allows comparison of outcomes, strengthening causal inferences (Kellam et al., 2019). However, in real-world settings, random assignment might be impractical due to ethical or logistical reasons, making a quasi-experimental design more appropriate. Limitations of this approach include potential threats to internal validity, such as selection bias or maturation effects, and limited generalizability if the sample is not representative of all parents in similar programs. Furthermore, client drop-out can introduce bias if those who leave differ systematically from
