Interpreting the Results of the Literature Review
Literature review summarization and search result interpretation are related processes in evidence-based practice, but they are not the same. A literature review summary is completed after the most relevant evidence has been selected and appraised. Its purpose is to synthesize what the chosen body of literature shows by identifying major themes, comparing findings, describing strengths and limitations, and recognizing gaps. In psychiatric-mental health practice, summarization helps the clinician explain what is known about a clinical topic in a clear and organized way. For example, a literature review summary of psychotherapy for histrionic personality disorder (HPD) may conclude that psychotherapy is the primary treatment approach, that emotional expression and interpersonal functioning are central treatment targets, and that direct comparative evidence for specific therapies remains limited.
Interpreting search results occurs earlier in the evidence review process. Instead of explaining what the final evidence means, interpretation determines which search results should be included in the review. This process requires critical appraisal of each article title, abstract, population, setting, study design, sample size, intervention, comparison group, outcome measures, and applicability to the PICO question. Melnyk and Fineout-Overholt (2023) emphasized that evidence-based practice requires more than collecting research; clinicians must judge the quality, relevance, and usefulness of the evidence. Therefore, search result interpretation answers the question, “Is this source strong enough and relevant enough to inform this clinical question?” Literature summarization answers the later question, “What does the selected evidence show?”
This distinction is important for psychiatric-mental health nurse practitioners (PMHNPs) because psychotherapy evidence for personality disorders is often complex. HPD is a Cluster B personality disorder characterized by excessive emotionality, attention seeking, dramatic expression, and interpersonal difficulties (American Psychiatric Association, 2022). The available literature is not as extensive as the evidence base for borderline personality disorder, depression, or anxiety disorders. As a result, PMHNPs must be careful not to overstate conclusions. A strong literature review summary depends on accurate search result interpretation first. If weak, outdated, non-peer-reviewed, or indirectly related sources are included without careful appraisal, the final summary may appear organized but still lead to inaccurate clinical conclusions.
Process Used to Interpret the Search Results for the PICO Question
The selected PICO question asks: In adults with histrionic personality disorder (P), how does emotion-focused therapy (I), compared with cognitive-behavioral therapy (CBT) (C), reduce exaggerated emotional expression in social settings (O)? This question was designed to compare two psychotherapy approaches for a clinically meaningful HPD symptom: exaggerated emotional expression in interpersonal or social contexts. Because HPD-specific treatment studies are limited, the interpretation process required attention to both directness of evidence and transferability from broader personality disorder research.
The first step in interpreting the search results was identifying the major concepts within the PICO question. These concepts included adults with HPD, emotion-focused therapy, CBT, exaggerated emotional expression, emotional regulation, interpersonal functioning, and social behavior. Search terms were developed from these concepts, including histrionic personality disorder, Cluster B personality disorder, emotion-focused therapy, cognitive-behavioral therapy, psychotherapy, emotional expression, emotional regulation, interpersonal functioning, and treatment outcomes. Boolean combinations such as “histrionic personality disorder AND psychotherapy,” “personality disorder AND emotion-focused therapy,” “Cluster B AND cognitive behavioral therapy,” and “personality disorder AND emotional regulation” were used to identify relevant evidence.
After retrieving search results, titles and abstracts were screened to determine whether each source addressed the PICO question directly or indirectly. Articles were prioritized if they focused on adults, HPD, Cluster B personality disorders, psychotherapy outcomes, EFT principles, CBT-based interventions, emotional processing, emotional regulation, or interpersonal functioning. Articles were excluded if they were older than five years, nonacademic, not peer reviewed, focused only on medication management, focused only on children or adolescents, or did not address personality disorder symptoms or psychotherapy. This step helped narrow the evidence to sources that could meaningfully inform the PICO question.
The next step was evaluating level of evidence and study design. Systematic reviews and meta-analyses were given the greatest weight because they synthesize findings from multiple studies. For example, d’Huart et al. (2023) provided broad evidence on the stability and changeability of personality disorder diagnoses and criteria over time. Banyard et al. (2021) examined CBT outcomes among patients with depression and comorbid personality disorders and concluded that personality disorder pathology should not exclude patients from evidence-based CBT, although the findings were not HPD-specific. These sources were useful because they provided higher-level evidence, but they also required cautious interpretation due to indirectness.
Direct HPD-specific evidence was interpreted differently. Babl et al. (2023) examined change processes in psychotherapy for patients presenting with HPD and found that relational processes between therapist and patient were meaningfully related to outcome. This article was highly relevant because it focused on HPD, but it did not directly compare EFT with CBT. Therefore, it was interpreted as direct evidence for the importance of psychotherapy process and the therapeutic relationship in HPD, not as proof that one therapy is superior. This distinction is important because relevance to the population does not automatically mean relevance to the intervention comparison.
Evidence related to EFT was interpreted by examining whether the treatment model matched the clinical outcome in the PICO question. Kramer and Timulak (2026) described emotion-focused therapy for personality disorders as an approach that targets emotional processing, emotion transformation, and emotion-focused therapeutic skills. This evidence is conceptually relevant to HPD because the disorder involves exaggerated emotional expression and interpersonal emotional dysregulation. However, because the article is a proof-of-concept synthesis rather than an HPD-specific randomized trial, it supports the rationale for EFT but does not provide definitive comparative effectiveness evidence.
Evidence related to CBT was interpreted by examining its relevance to cognition, behavior, and interpersonal patterns in personality disorders. Carreiras et al. (2024) described CBT approaches for personality disorders, including schema therapy, cognitive interpersonal therapy, and dialectical behavior therapy. These CBT-informed models are relevant because HPD symptoms may involve maladaptive beliefs about approval, attention, relationships, and self-worth. CBT may help patients identify and modify dysfunctional patterns that contribute to dramatic or attention-seeking behavior. However, because much of the CBT evidence is broader than HPD, the findings should be applied cautiously and individualized to the patient’s symptom profile.
After appraisal, the search results were interpreted by comparing directness, quality, and clinical usefulness. The strongest conclusion was not that EFT is clearly superior to CBT or that CBT is clearly superior to EFT. Instead, the evidence suggests that both approaches may be clinically useful but may target different mechanisms. EFT appears especially relevant to exaggerated emotional expression because it focuses on emotional awareness, processing, and transformation. CBT appears especially relevant to maladaptive thoughts, interpersonal beliefs, behavioral patterns, and coping strategies. For an adult with HPD, the choice of therapy may depend on whether the patient’s most impairing symptoms are primarily emotional, cognitive, behavioral, interpersonal, or mixed.
Overall, interpreting the search results showed that the PICO question is clinically important but that the evidence base is limited and indirect. A literature review summary could state that psychotherapy is central to HPD treatment and that both emotion-focused and CBT-based approaches have theoretical and clinical value. However, search result interpretation adds a deeper conclusion: the current literature does not provide enough direct comparative evidence to claim that EFT is definitively better than CBT for reducing exaggerated emotional expression in HPD. For PMHNP practice, this distinction supports safer evidence-based decision-making. Rather than overgeneralizing, the PMHNP should use the best available evidence, consider patient-specific symptoms, evaluate treatment response over time, and collaborate with psychotherapy providers to select an intervention that matches the patient’s needs.

Discussion 2 (peer 2) - Carlos
Access to timely psychiatric care remains a significant challenge for veterans diagnosed with post-traumatic stress disorder (PTSD) and depression. This discussion compares the processes of summarizing a literature review and interpreting search results within evidence-based practice. While summarization focuses on describing existing evidence, interpretation requires critical appraisal of methodological rigor, evidence quality, consistency of findings, potential sources of bias, and clinical applicability. The selected PICO question examined whether rapid-access psychiatric care models utilizing telehealth and community care referrals improve appointment wait times, treatment engagement, and mental health outcomes among veterans with PTSD and depression. Interpretation of the literature revealed consistent evidence supporting telehealth-enabled psychiatric services as a strategy to improve healthcare accessibility, continuity of care, and treatment engagement. Consideration was also given to evidence hierarchy, publication bias, external validity, and the translation of research findings into clinical practice. The ability to critically interpret evidence is essential for psychiatric mental health nurse practitioners (PMHNPs) seeking to implement evidence-based interventions that improve mental healthcare access and outcomes for veteran populations.

Comparing Literature Summarization and Search Result Interpretation
Summarizing a literature review and interpreting search results are related but distinct components of evidence-based practice. Summarizing the literature involves describing the findings, methodologies, and conclusions of individual studies. Its purpose is to provide an organized overview of the available evidence and identify recurring themes across the literature. In essence, summarization answers the question, “What does the literature say?” and serves as the foundation for evidence synthesis (Melnyk & Fineout-Overholt, 2023).
Interpreting search results requires a deeper level of analysis. Rather than simply reporting findings, interpretation involves evaluating the quality, consistency, and applicability of the evidence while identifying methodological limitations and potential sources of bias. Interpretation answers the question, “What do these findings mean, and how should they influence practice?” (Eriksen & Frandsen, 2021). For PMHNPs, this distinction is critical because clinical decisions must be based not only on the existence of evidence but also on its strength, relevance, and clinical applicability.
Interpretation of Search Results for the PICO Question
The selected PICO question examined whether rapid-access psychiatric care models utilizing telehealth and community care referrals improve appointment wait times, treatment engagement, and mental health outcomes among veterans diagnosed with PTSD and depression compared with traditional scheduling practices. The interpretation process began after the literature search and screening phases were completed. Studies were first evaluated according to their position within the evidence hierarchy. Systematic reviews and meta-analyses were prioritized because they provide the highest level of evidence through the synthesis of multiple investigations. Randomized controlled trials and high-quality cohort studies were also given significant weight because of their methodological rigor and ability to reduce bias (Melnyk & Fineout-Overholt, 2023).
Several important patterns emerged from the search results. First, delayed access to psychiatric services was consistently identified as a significant barrier to treatment engagement among veterans with PTSD and depression. Second, telehealth interventions were associated with improved appointment attendance, reduced geographic barriers, and increased continuity of care, particularly among veterans residing in rural and underserved communities (Connolly et al., 2022). Third, the literature demonstrated that improving access to psychiatric services does not necessarily guarantee improved long-term outcomes. Several studies suggested that treatment engagement, continuity of care, and participation in evidence-based interventions remain important determinants of recovery among veterans with PTSD and depression (Norman et al., 2023; Saulnier et al., 2024).
Across the evidence hierarchy, the strongest evidence emerged from systematic reviews and large observational cohort studies, which consistently demonstrated improvements in healthcare accessibility, treatment engagement, and continuity of care among veterans receiving telehealth-enabled psychiatric services. The convergence of findings across multiple study designs increased confidence in the reliability and transferability of the evidence to PMHNP practice. This alignment of results strengthened confidence in the overall conclusions and increased the clinical applicability of the evidence. This process of evidence synthesis supported translation into practice by identifying interventions most likely to improve both access and outcomes for veterans with PTSD and depression.
Interpretation also required careful evaluation of study limitations. Several studies relied on observational designs, which may introduce confounding variables and limit causal inference. Additionally, some investigations examined general psychiatric populations rather than veterans specifically, reducing external validity and limiting direct applicability to the target population. Furthermore, mental health outcomes among veterans may be influenced by multiple clinical, social, and healthcare system factors beyond access alone, making it important to distinguish between intervention effectiveness and broader barriers that may affect treatment engagement and continuity of care (Norman et al., 2023). These limitations were considered when determining the strength of the evidence.
Another important aspect of interpretation involved determining whether the identified interventions addressed all components of the PICO question. Although telehealth consistently improved access-to-care measures, some studies reported mixed findings regarding long-term symptom reduction and treatment retention. Consequently, interpretation focused not only on appointment availability but also on treatment engagement, continuity of care, and meaningful mental health outcomes.
Potential biases within the literature were also considered. Publication bias may result in studies with positive findings being published more frequently than studies reporting neutral or negative outcomes. Database bias may occur because different databases emphasize different disciplines and methodologies. Utilizing multiple databases helped improve the comprehensiveness of the review and reduce the likelihood of overlooking relevant evidence (Eriksen & Frandsen, 2021). Therefore, critical appraisal of methodological rigor, external validity, and study quality was necessary before translating findings into clinical recommendations.
Implications for Advanced Psychiatric Nursing Practice
Interpreting search results allowed the evidence to be translated into meaningful recommendations for PMHNP practice. The collective findings suggest that telehealth services, rapid-access psychiatric care models, and community referral pathways have the potential to improve mental healthcare access among veterans experiencing PTSD and depression. However, the evidence also indicates that access alone does not guarantee improved outcomes. Factors such as treatment engagement, continuity of care, social support, and healthcare system navigation remain important determinants of long-term success (Norman et al., 2023).
For PMHNPs, the ability to interpret evidence is essential for making informed clinical decisions and advocating for evidence-based interventions. Veterans frequently encounter barriers related to provider shortages, geographic limitations, stigma, and delayed access to care. By critically appraising and synthesizing research findings, PMHNPs can identify interventions that not only improve healthcare accessibility but also enhance treatment engagement and overall mental health outcomes.
Conclusion
Summarizing a literature review and interpreting search results are complementary but distinct processes within evidence-based practice. While summarization focuses on describing the available evidence, interpretation requires critical appraisal of methodological rigor, consistency of findings, potential sources of bias, and clinical applicability. For the selected PICO question, interpretation of the literature revealed that rapid-access psychiatric care models, telehealth services, and community referral pathways may improve mental healthcare access for veterans with PTSD and depression. However, the evidence also demonstrated that sustainable improvements in outcomes depend on factors beyond access alone, including treatment engagement, continuity of care, and healthcare system capacity.
From an advanced practice nursing perspective, interpreting search results transforms individual study findings into meaningful clinical recommendations. By critically appraising, synthesizing, and applying evidence, PMHNPs can bridge the gap between research and practice while advocating for interventions that improve access to care and mental health outcomes among veterans. As healthcare systems continue to address growing demands for psychiatric services, evidence-based interpretation remains an essential competency for improving the quality, accessibility, and effectiveness of veteran mental healthcare.
