More specifically, in order to reduce the effect of maturation and regression to the mean, we can add another pretest measure. For example, if a hospital were to introduce a new protocol to reduce infection rates, researchers could compare infection rates before and after the implementation to determine if the intervention was effective.

Pros and Cons of Pretest-Posttest Design
If more than two measurement occasions are available, other statistical tools can be used to assess individual change (e.g., Estrada et al., 2018). These tools are particularly useful for examining developmental and learning processes, and can incorporate measurement error. A gain or difference score takes two points of data for a participant, such as a pre- and post-test, and calculates one score to represent the change over time. For example, a student who got a 50% on a midterm and 90% on the final exam would have a gain score of 40%, suggesting large improvements.
How to Interpret Sig. (2-Tailed) Values in SPSS
The nurse was finally requested to propose proper management of each paper case. It has been observed that it is more difficult to conduct a good quasi-experiment than to conduct a good randomized trial (43). Although QEDs are increasingly used, it is important to note that randomized designs are still preferred over quasi-experiments except where randomization is not possible. In this paper we present three important QEDs and variants nested within them that can increase internal validity while also improving external validity considerations, and present case studies employing these techniques. Frameworks can be helpful to enhances interpretability of many kinds of studies, including QEDs and can help ensure that information on essential implementation strategies are included in the results (44).
Pretest, posttest, and intervention
VP uses a computer or tablet screen that allows the users to conduct a complete patient history, make a physical examination, request laboratory or imaging examination, make a diagnosis, and thereafter make a management plan [5, 6]. The literature indicates that VP cases can help learners acquire communication and clinical reasoning skills, but many authors attribute the use of VP cases to especially training clinical reasoning skills [7,8,9]. A VP case reflects real patient case scenarios where software responds to the asked question as a patient could do and this feature provides a realistic and engaging learning environment in health education [10]. These interactive features, enable the learners to acquire clinical reasoning competencies [11].

The participants who did not complete the study filled in the pre-tests and started the CPD through VP cases but reported insufficient time to finish all VP cases. The Ministry of Health in Rwanda employs both face-to-face and, more recently, online approaches for delivering CPD to nurses. This traditional approach to CPD primarily relies on Multiple Choice Questions (MCQs) to evaluate the learning outcomes after CPD training. This study used a different CPD approach (VP cases) to train and evaluate the outcomes. The current study focused especially on skills for early disease detection, consequently promoting appropriate management among in-service nurses working at health centers.
The data that support the findings of this study are available from the first and corresponding author, Osita Ezenwosu. Participants signed the informed consent to participate and were reminded about their right to withdraw from this study at any time without any negative impact. The study was funded by the Swedish International Development Cooperation Agency (SIDA) in the University of Rwanda-Sweden Research Partnership 2019–2024 grant (No 11277). The datasets used during the current study are not available due to a lack of ethical authorization for sharing raw data. However, they can be obtained from the corresponding author on reasonable request. Please refer to Table 1 below for the demographic data of the included respondents.

Thus, researchers requested the list of all nurses from the head of the health center and randomly selected potential participants. A nurse who was selected and did not fulfill the inclusion criteria or did not accept to participate in the study was randomly replaced by another nurse. Depending on inclusion criteria and willingness to participate, participants at each health center ranged from 4 to 8 nurses. “Virtual patients are interactive computer simulations of real-life clinical scenarios for the purpose of healthcare and medical training, education, or assessment ([4] p.170).
Introduction to Quadratic Discriminant Analysis
The scarcity of studies on this topic and the lack of sound conclusions suggest that more research is needed to understand the relation between the change in the distribution center and the percentage of individual changes. This design allows the study of two interventions in the same trial without unduly increasing the required number of participants, as also the study of interaction between the two treatments. In previous articles in this series, we introduced the concept of study designs[1] and have described in detail the observational study designs – descriptive[2] as well as analytical.[3] In this and another future piece, we will discuss the interventional study designs.
Such interventions typically include on one or more of the “7 Ps” (programs, practices, principles, procedures, products, pills, and policies) (9). Increasingly, both public health and clinical research have sought to generate practice-based evidence on a wide range of interventions, which in turn has led to a greater focus on intervention research designs that can be applied in real-world settings (2, 8, 9, 20, 25, 26, 10, 2). This paper examines the assessment of change through individuals' responses to standardized tests.
A newly graduated nurse working at health centers in Rwanda is typically assigned to the consultation room. This working environment restricts the opportunities for nurses at health centers to interact with colleagues, making VP cases a valuable tool to help them stay up-to-date with managing diverse medical cases. The participants' education level was another variable that could have resulted in different scores.
You will administer a pretest on general knowledge and judgment, then have your experimental manipulation of the participants not cleaning themselves, then perform a posttest using the same or similar tests. Finally, in pre-post designs, it is often challenging to blind participants, researchers, or outcome assessors to the intervention status. The absence of blinding can also introduce bias; if participants or researchers have any preconceived notions or expectations regarding the intervention, these could influence their behavior and/or the reported outcomes. A pre-post study design is a research methodology used to evaluate the effectiveness of treatments by comparing results measured before and after an intervention. It is commonly used in clinical trials, but can also be applied more broadly in other scientific contexts.
Of these, the most commonly used and possibly the strongest design is a randomized controlled trial (RCT). To measure a difference, we need to measure the level at which students start, such as their prior knowledge, and the level at which students finish, such as after a course or intervention, to make claims about how they’ve changed. The type of design that measures before (pre-test) and after (post-test) an intervention is called a pre-post design. This design is good at measuring any change from before the research started to after, such as how students’ perceptions of computer science differ from the beginning to the end of a course. A pretest-posttest is a quasi-experiment where participants are studied before and after the experimental manipulation.
A questionnaire that assesses the residents’ knowledge on the subject was used as a pre- and posttest. There was a statistically significant decrease in the anxiety score between the pretest and the posttest from 46.8 to 39.3. Administer some treatment procedure to individuals in the treatment group and administer some standard procedure to individuals in the control group.
