Study summary
Schizophrenia is a chronic mental health condition marked by positive symptoms (delusions, hallucinations, disorganized thinking) and negative symptoms (a general flattening of normal mental activity, such as reduced motivation or emotional expression). Consistent antipsychotic medication use is central to keeping the condition stable, yet research consistently shows that many patients diagnosed with schizophrenia struggle to take their medication as prescribed. When patients stop or skip medication, symptoms can return or worsen, often leading to repeat hospitalizations and a lower overall quality of life.
This DNP (Doctor of Nursing Practice) project, completed by Patience Madu at Walden University, tackled this problem from the staff side rather than the patient side. Instead of asking patients why they don't take medication, the project asked a different practice-focused question: does an educational program delivered to staff nurses increase nurses' knowledge of how to encourage medication adherence among patients diagnosed with schizophrenia? The logic is straightforward: if bedside and mental health nurses understand why patients stop taking medication and have concrete strategies to respond, they are better positioned to support adherence during everyday care.
The program was built around the health belief model (HBM), a framework commonly used in health education. The HBM proposes that a person's health behavior is shaped by how they perceive the threat of their condition, the benefits of treatment, the barriers to following through, and their own confidence in managing it. By training nurses on these HBM concepts, the project aimed to help them recognize why an individual patient with schizophrenia might resist medication (for example, side effects, lack of insight, or mistrust) and to respond with specific, actionable strategies rather than generic reminders.
To test whether the education actually worked, the project used a pre-survey/post-survey design. Nurses completed a knowledge survey before the educational session and the same or a comparable survey afterward. The two data sets were compared using a paired t-test (which checks whether the average score changed significantly for the same group of people from one time point to another) and a Pearson correlation (which checks whether variables move together, such as whether higher pre-test scores predicted higher post-test scores). The result was a statistically significant increase in nurses' knowledge, with a p-value of less than 0.05. In plain terms, a p-value under 0.05 means the improvement seen after the education was very unlikely to be due to chance alone, which supports the conclusion that the program did what it set out to do.
It's worth being precise about what this finding does and doesn't show. The abstract confirms that nurses' knowledge increased after the educational intervention. It does not report the number of nurses who participated, the exact survey instrument used, or whether the knowledge gains translated into a measurable change in patient medication adherence, hospitalization rates, or other clinical outcomes. Those details may exist in the full dissertation text, but they are not part of the abstract available for this summary, so they should not be assumed.
For nursing students, this project is a good illustration of a quality-improvement-style DNP project: identify a real clinical problem (medication noncompliance in schizophrenia), pick a theoretical framework to structure the intervention (the health belief model), design a low-burden staff intervention (an education session), and measure the outcome with a simple, appropriate statistical test (paired t-test, Pearson correlation) rather than a large randomized trial. This is a common and appropriate design for practice-focused doctoral projects, where the goal is local improvement rather than generalizable research.
The broader context also matters. Medication noncompliance in schizophrenia is a well-documented problem in psychiatric nursing literature, and it carries consequences for both individuals and health systems: symptom relapse, more frequent psychiatric hospitalizations, and reduced quality of life for patients and families. In Canadian practice, supporting medication adherence and patient teaching fall squarely within registered nurses' scope, and unit-based in-service education like this mirrors the kind of continuing-competence activity provincial regulators expect nurses to undertake. Projects that strengthen nurses' knowledge and skills around adherence-supporting conversations are one piece of addressing that larger pattern, even though a single staff education session is unlikely to solve noncompliance on its own. Students should read this project as evidence that staff education can move the needle on nurse knowledge, while remembering that knowledge gains among staff are a step toward, not a guarantee of, improved patient-level medication adherence.

Medication noncompliance is a significant challenge in managing schizophrenia, a chronic and severe mental health disorder characterized by symptoms such as delusions, hallucinations, disorganized thinking, and impaired functioning. Schizophrenia presents both positive symptoms, which involve exaggerated thoughts or behaviors, and negative symptoms, which reflect a lack of normal mental activity. Consistent medication management is important for stabilizing this condition. However, research shows that many patients with schizophrenia struggle with medication adherence. In this executive summary, I outline the staff education program I designed to equip mental health nurses with skills, knowledge, and strategies to address medication noncompliance. The practice-focused question I sought to answer was, does an educational program delivered to staff nurses increase nurses' knowledge of how to encourage medication adherence among patients diagnosed with schizophrenia?I based the program on the health belief model (HBM) with the intent to help participating nurses understand the factors contributing to noncompliance and provide actionable strategies to promote adherence. The program's effectiveness was assessed through pre- and post-surveys, with the data analyzed using a paired t test and Pearson correlation. The results demonstrated a significant increase in knowledge, with a p value of less than 0.05, indicating the program's success in improving nurses' ability to manage medication adherence. Medication noncompliance has serious consequences for both individuals and society, including symptoms exacerbation, frequent hospitalizations, and a decline in patients' quality of life. By enhancing nurses' knowledge, this program may enable nurses to better educate patients and promote medication compliance.
Reviewed findings
Main findings
- The project tested whether a staff education program increases nurses' knowledge of strategies to encourage medication adherence among patients diagnosed with schizophrenia.
- The educational intervention was built on the health belief model (HBM), used to help nurses understand factors behind medication noncompliance and identify actionable adherence-promoting strategies.
- Nurses' knowledge was assessed with a pre-survey before the education and a post-survey afterward, allowing a before-and-after comparison.
- Data were analyzed using a paired t-test and a Pearson correlation, and the results showed a statistically significant increase in nurses' knowledge (p < 0.05).
- The abstract frames medication noncompliance in schizophrenia as a driver of symptom exacerbation, frequent hospitalizations, and reduced quality of life, which is the clinical problem the education program was designed to help address indirectly through nurse knowledge.
For teaching and learning
Education implications
- Structured, theory-based staff education (using a framework like the health belief model) may be an effective way to improve nurses' knowledge of medication adherence strategies for patients with schizophrenia.
- Nurses equipped with HBM-informed knowledge may be better positioned to identify individual patients' perceived barriers to medication (e.g., side effects, low perceived severity, mistrust) and tailor conversations accordingly.
- Improving staff knowledge is a plausible first step toward supporting patient medication adherence, though this project measured nurse knowledge, not confirmed changes in patient adherence or hospitalization rates.
- Pre/post knowledge surveys with paired statistical testing offer a practical, low-resource way for units to evaluate whether an in-service education session achieved its immediate learning goal.
- Given the documented consequences of schizophrenia medication noncompliance (relapse, rehospitalization, reduced quality of life), embedding adherence-focused content into ongoing psychiatric nursing education may have downstream value for unit-level care quality, pending further outcome evaluation.

Teaching and appraisal notes
This is a Doctor of Nursing Practice (DNP) project by Patience Madu, completed at Walden University's School of Nursing (2024, Walden ScholarWorks dissertation record 16734), addressing medication noncompliance among patients diagnosed with schizophrenia through a staff-facing educational intervention rather than a patient-facing one. The practice-focused question was whether an educational program delivered to staff nurses would increase nurses' knowledge of strategies to encourage medication adherence in this population.
The project is theoretically grounded in the health belief model (HBM), which frames health behavior as a function of perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy. Using the HBM as an organizing framework for staff education is a reasonable choice given the model's long history in adherence-focused patient education, though it is worth noting for discussion that some current literature on schizophrenia-specific adherence questions how well purely cognitive/rational models like the HBM capture adherence behavior in a population where insight, cognition, and illness awareness are themselves affected by the disorder. This is useful supplementary context, not a critique found in the source abstract itself.
Methodologically, the project used a single-group pre-survey/post-survey design around the educational intervention, with data analyzed via a paired t-test and Pearson correlation. The paired t-test is an appropriate choice for detecting whether the same group of nurses' knowledge scores changed meaningfully from before to after the intervention, and the Pearson correlation adds information about the relationship between pre- and post-scores. The abstract reports a statistically significant increase in knowledge (p < 0.05), which supports the project's core practice-focused question. However, the abstract does not specify the sample size, the survey instrument's validity/reliability, the length or format of the educational session, or the clinical setting and unit type, all of which are important for appraising internal validity and transferability. These are gaps for students to identify explicitly, not findings to infer.
As a project design, this reflects a common and defensible approach for DNP scholarly work: a pre/post, single-site staff education evaluation using validated statistical tests, targeting a proximal outcome (nurse knowledge) rather than a distal outcome (patient medication adherence or rehospitalization rates). Faculty may want to use this as a teaching example of the distinction between 'did the education work on staff knowledge' and 'did the intervention change patient outcomes' — the former is what this project measured and supports, the latter is not established by this abstract and should not be implied in class discussion without caveat.
Discussion angles for seminar: (1) appropriateness of the HBM for staff education about a patient population with variable insight; (2) the strength of evidence a single pre/post knowledge survey provides compared to a controlled or longitudinal design; (3) how knowledge gains among nurses might (or might not) translate into behavior change and, eventually, patient-level adherence; (4) what additional outcome measures (e.g., a validated medication adherence scale, rehospitalization audit, or patient-reported outcomes at a follow-up interval) would strengthen a next iteration of this quality improvement work; and (5) the broader clinical and system-level stakes of schizophrenia medication noncompliance — symptom relapse, hospitalization burden, and quality of life — that motivate this line of DNP practice-improvement scholarship. Full dissertation text (via Walden University ScholarWorks, dissertation record 16734) may contain additional detail on sample size, instrument, and setting not captured in the publicly available abstract; instructors with institutional access should verify before presenting specific figures beyond what is summarized here.
Critical appraisal
Limitations
- The publicly available abstract does not report the sample size (number of nurses who participated), limiting assessment of statistical power and generalizability.
- The project used a single-group pre/post design without a comparison or control group, so the observed knowledge increase cannot be definitively attributed to the education program alone versus other factors (e.g., test familiarity).
- The abstract does not describe the survey instrument's validity or reliability, nor its length, making it difficult to judge how precisely nurse knowledge was measured.
Classroom use
Discussion Questions
- Why might staff (nurse) education be a reasonable first target for addressing medication noncompliance in schizophrenia, compared to intervening directly with patients?
- How does the health belief model explain why a patient with schizophrenia might not take prescribed medication, and what are its potential limits for this population?
- What is the difference between a paired t-test and an independent-samples t-test, and why is a paired t-test appropriate for a pre/post staff education evaluation?
- What does a p-value of less than 0.05 tell you, and what does it NOT tell you, about the size or clinical significance of the knowledge change?
- What information would you want to know about the sample (number and type of nurses, unit, setting) before deciding how much weight to give this project's findings?
- If you were extending this project, what patient-level outcome measure (e.g., a validated adherence scale, rehospitalization rate) would you add, and why?
Source-based questions
Frequently asked questions
Why does medication adherence matter in schizophrenia?
According to the abstract, medication noncompliance in schizophrenia can lead to symptom exacerbation, frequent hospitalizations, and a decline in patients' quality of life, making adherence support an important nursing priority.
Did this project measure whether patients actually took their medication more consistently afterward?
Based on the available abstract, no — the project measured nurses' knowledge before and after the education, not direct patient medication adherence or hospitalization outcomes.
What statistical test is a paired t test, and why was it used here?
A paired t test compares two related sets of scores from the same group at two time points (here, nurses' pre- and post-education survey scores) to see if the change is statistically significant.
