Nursing Research Research design qualitative studies ch.10&11

qualitative research design study of human experiences in a holistic fashion in order to interpret and understand phenomena, guide practice, and develop theory **an emergent design**
characteristics of qualitative design -no manipulation, no control/treatment grps, no randomization, no hypotheses -researcher is an active agent -flexibility in who, what, when, where, and how to collect data -use of diverse and lengthy data collection strategies (interviewing)
goal of qualitative design to describe, interpret, and understand meaning of phenomena in a natural setting
types of qualitative designs -ethnographic -phenomenological -grounded theory -historical analysis
ethnographic design -scientific study of the meanings, patterns, and experiences of a defined cultural group -macroethnography: depression in N.A, homosexuality in haitians -microethnography: children of incarcerated parents, homeless veterans, circumcised females
phenomenological design scientific study of essence and meaning of the lived experiences of humans...the phenomena associated with "being in the world" (ex: grieving loss of self in persons with cancer, grieving loss of another in death of twin, stress of awaiting a kidney)
grounded theory design ex: chinese persons with cancer overcoming powerlessness, migrant workers with HTN achieving self efficacy, rural community response to loss of health care services) scientific study of basic social processes and social structures occurring in a social setting...associated with a social problem that a defined group experiences and the processes instituted to cope with or resolve the problem
historical analysis design scientific study of causes, effects, and relationships associated with a past event to better understand current behaviors ex: strategies of nurses in reducing mortality during the Crimean war, development of the "doctor's handmaiden" concept in nursing
study designs -retrospective ex emotional impact of living with a pacemaker) -prospective ex evolution of strategies to minimize fatigue in patients with cancer) -crosssectional ex spousal experience of a heart transplant) -longitudinal ex mothers exp. of 1st pregn
concepts of qualitative research: data saturation discontinuing data collection when it becomes repetitive; no new info being gathered
concepts of qualitative research: bracketing identifying and setting aside researcher's personal biases concerning phenomenon being studied
concepts of qualitative research: bricolage collecting data from a variety of sources (primary or secondary)
quantitative designs -compartmental -obj. -explore relationships -large sample -extensive approach -use of instruments in a controlled manner -computer to arrange and analyze data -deductive analysis (whole to parts)
qualitative designs -holistic -subj. -explore experiences -small sample -intensive approach -use of interviews, observations -computer to manage data -inductive analysis (parts to whole)
evaluation research purpose: assess effectiveness of a program, practice, procedure, or policy focus: process, impact, outcome, or cost-benefit analysis design: all quantitative designs involving interventions
outcomes research purpose: assess effectiveness of health care services focus: structure, process, or outcomes of large scale or global services design: non-experimental designs as no interventions involved
