PartI: PICO Analysis of Research Topic
P:Patient or Population
I:Anticipated Intervention
C:Comparison group or Current standard
O:Outcome desired
Source:Adapted from Elkins (2010)
Step1: Frame your clinical question using the PICO method.
P:For critically-ill patients
I:Higher number of registered nurses
C:Non-registered nurses
O:Reduction in medical errors
PartII: Search Strategy

(Sonuga-Barke, Bitsakou, & Thompson, 2010) |
Dual Pathway Model |
Understanding inhibitory deficits at an early stage is crucial to treatment of dissociative disorder |
Case-control |
Value of distinction between motivational and cognitive pathways |
Sample size was small which limited the scope. Use of community based procedure that identified only one approach. |
Level IV |
|
(Klein et al., 2010) |
Inhibitory deficits in AD/HD can be noted early in development |
Open trial evaluation |
Existence of motivational and cognitive basis may improve diagnosis and treatment |
Study was an open trial that lacked control groups. The moderate power levels may underestimate efficiency of PTSD |

Step2: Briefly summarize the history and purpose of your researchquestion.
Treatmentof dissociative disorders has become a problem for mostpractitioners. The research question proposes the use ofpsychotherapy as an intervention that focuses on the cognitive andemotional well-being of the individual. Research has proved thatpsychotherapy can be useful in promoting better coping mechanisms.
Step3: Analysis of strengths and weaknesses of existing literature.
|
Strengths |
Weaknesses |
|
Insights into available theory |
Open trials that are not representative |
|
Correlation of different interventions |
Sample size is limited |
Step4: What gap exists in the current literature? Explain.
Theavailable research shows a need for earlier intervention to ensurethat patients are attended to avoid progression of dissociativedisorders. Psychotherapy has not been explored as one of theapproaches in dealing with the disorders which poses a gap forresearch.
PartIV: Identify the influence of empiricism on quantitative researchmethodology. Discuss its applicability to evidenced-based practiceprojects.
Empiricismis used in methodology section of quantitative research where the usef primary research articles is emphasized as it helps investigate acertain hypothesis. This is crucial in EBP to promote understandingof available knowledge and build on it through research to improvehealth care practice.
