a. Select a theory from a discipline other than nursing.b. Discuss how that theory could support your PICO question problem area and project. c. Discuss the theory origin, concepts, propositions,empirical adequacy, and pragmatic adequacy.NOTE:PICOT question: Will the use of PHQ scale identify and reduce the rate of readmission of depressed patients on an in-patient psychiatry unit?Using the PICOT acronym, my potential components to address my clinical problem are as follows:Population of interest (P)- Depressed patients (adult population) admitted on an in-patient psychiatric unit at the Cincinnati VA Medical Center(CVAMC).Intervention (I) -The use of Patient Health Questionnaire (PHQ) depression scale to predict and reduce readmission rate on an in-patientpsychiatric unit. Manea et. al., (2012) relayed that the PHQ scale is a reliable and valid tool in carrying out the diagnosis of depressionamong individuals.Comparison intervention or group (C)- This could be inpatient admission of patients without the diagnosis of depression on the medical unit.However, this group may not be included in the study.Outcome (O)- The outcome of the intervention is to predict and reduce the rate of re-hospitalization among depressed patients on the In-PatientPsychiatry unit and serve as an important tool in guiding treatment decisions.
