qualitative study design
Unstructured Interviews
research has a general idea of topics, but what happens during the interview leads the researcher
A type I error occurs when
you reject null when it is true "false positive"
characteristics of phenomenology
1. Ordinary Members Phenomenology focuses on the ways in which ordinary members of society attend to their everyday lives. 2. Subjective Materials Phenomenology seeks to draw meaning from complex realities through careful analysis of narrative subjective materials. 3. Voice Phenomenology gives voice to the person being studied and requires that the researcher present the subject's view of his/her world.
According to Finn et al (2005), the criteria for distinguishing between science and pseudoscience are as follows:
1. Untestable: Is the treatment unable to be tested or disproved? 2. Unchanged: Does the treatment approach remain unchanged even in the face of contradictory evidence? 3. Confirming Evidence: Is the rationale for the treatment approach based only on confirming evidence with disconfirming evidence ignored or minimized? 4. Anecdotal Evidence: Does the evidence in support of the treatment rely on personal experience and anecdotal accounts? 5. Inadequate Evidence: Are the treatment claims incommensurate with the level of evidence needed to support those claims? 6. Avoiding Peer Review: Are treatment claims unsupported by evidence that has undergone critical scrutiny? 7. Disconnected: Is the treatment approach disconnected from well-established scientific models or paradigms? 8. New Terms: Is the treatment described by terms that appear to be scientific but upon further examination are found not to be scientific at all? 9. Grandiose Outcomes: Is the treatment approach based on grandiose claims or poorly specified outcomes? 10. Holistic: Is the treatment claimed to make sense only within a vaguely described holistic framework?
Organization, entity, individual, or event, and uses interviews, documents, reports, and observations to come up with a comprehensive description of a patient's history, current status, and response to an intervention.
Case study
The following is an example of which type of qualitative study? Impact of a Child-Based Health Promotion Service-Learning Project on the Growth of Occupational Therapy Students This study revealed the lived experiences of occupational therapy students as they embarked on a semester-long volunteer health promotion service-learning project during their entry-level master's program. Data analysis extrapolated themes from student journals, transcriptions of pre-and-post interviews, and field notes. Student roles were exemplified by what students wanted to learn, what they actually learned, and the unexpected benefits they experienced. In particular, issues with teaming, interprofessional development, and time management were discovered. The findings add to the growing literature about the benefits of service-learning as a teaching strategy and how it facilitates mindfulness of community service, communication, and clinical reasoning of future therapists. Implications for learning and practice are discussed.
b. Phenomenological
Harm Questions
Does the diagnostic procedure, treatment, or therapy increase harm to the patient - increased incidence of side effects, major safety events, hospitalization, death, disability, or major health events? Do the benefits outweigh the risks?
Prognosis Questions
Does the procedure, treatment or therapy increase the quality of life or length of mortality, or does it decrease associated complications or associated costs of care? Does the intervention of interest add value to traditional treatment?
Relevance to your Question
Does this study investigate a population similar to my client? Does the study review an intervention that I could use to advance my client's goals? Are the study's outcomes related to my question? If the study does not perfectly match my PICO elements, can it provide clinically relevant insights to guide clinical decisions?

Explains Phenomenon The goal of Grounded Theory is to explain the phenomenon being studied through the analysis of relationships among concepts. 3. Research Hypothesis Grounded Theory allows the researcher to develop research hypotheses as the data unfolds using inductive processes. 4. Theory Theory can be developed as the data unfold. 5.Observations The researcher collects, codes, and analyzes data simultaneously, identifying relevant variables, which may lead to the development of theoretical concepts that are "grounded" in the observations.
What does qualitative research do?
1. Explores how human behavior is philosophically different than quantitative research designs 2. Describes the nature of humans and how individuals perceive their own experiences within a specific social context 3.

Results and Conclusions
Are there limitations & bias? What is the significance of the results (e.g., Effect size? Implications for your practice? Relevance? Generalizable?)?
Systematic Reviews
At the top of the evidence pyramid are systematic reviews. Systematic reviews provide the strongest research evidence, since they answer specific research questions in review of existing literature. They employ a specific methodology to reduce bias (i.e., identify, evaluate, and summarize), which leads to credible sources of evidence. Qualitative (Meta-Synthesis) Quantitative (Meta-Analysis)
Structured Interviews
oral administration of a written questionnaire
The following is an example of which type of qualitative study? The Use of Animal-Assisted Therapy in Combination with Physical Therapy in an Inpatient Rehabilitation Facility Background Animal-assisted therapy (AAT) is a growing form of intervention in the field of rehabilitation often with the goals of decreasing pain, anxiety, and depression. There is a lack of literature on the use of AAT in inpatient rehabilitation facilities (IRF). Materials and methods This patient was treated with standard of care physical and occupational therapy in an IRF with the addition of AAT within 32% of the therapy sessions. AAT sessions focused on sitting and standing tolerance, standing balance, endurance, ambulation, stair negotiation and kitchen mobility. Clinical measures included the 6 Minute Walk Test (6MWT), the Functional Independence Measure (FIM) total score and the FIM motor subscale score. Clinical findings From admission to discharge from the IRF, change was noted in the areas of sitting tolerance, total FIM score, the motor subscale score of the FIM, and on 6MWT distance. Due to other therapies simultaneously occurring, no conclusions on AAT as a treatment can be made. AAT did provide more opportunities for this patient to engage in therapeutic activities. Conclusion AAT was used during PT, in attempt to facilitate participation and distract from pain in order to work on therapeutic activities and achieve the patient's functional goals. This case report can be used as a model for other IRF therapy programs interested in AAT, can provide information about a therapeutic modality and hopefully will inspire future rigorously designed research studies.

The following is an example of which type of qualitative study? Delivering High Quality Hip Fracture Rehabilitation: The Perspective of Occupational and Physical Therapy Practioners. Aim: The majority of post-acute hip fracture rehabilitation in the US is delivered in skilled nursing facilities (SNFs). Currently, there are limited guidelines that equip occupational and physical therapy practitioners with a summary of what constitutes evidence-based high quality rehabilitation. Thus, this study aimed to identify rehabilitation practitioners' perspectives on the practices that constitute high quality hip fracture rehabilitation. Methods: Focus groups were conducted with 99 occupational and physical therapy practitioners working in SNFs in southern California. Purposive sampling of facilities was conducted to capture variation in key characteristics known to impact care delivery for this patient population (e.g., financial resources, staffing, and patient case-mix). Questions aimed to elicit practitioners' perspectives on high quality hip fracture rehabilitation practices. Each session was audio-recorded and transcribed. Data were systematically analyzed using a modified grounded theory approach.

Meta-analysis
The following is an example of which type of qualitative study? A Qualitative Analysis of Burn Injury and Recovery on Peer Support Websites Methods: This qualitative enquiry began with a comprehensive overview of burn narratives on survivor peer generated websites. We conducted a purposeful sampling of 21 biographies posted on burn survivor peer and patient support websites. Participants with greater than 30% burn injury were included that provided narrative and discourse regarding burn recovery and survivorship. Underlying story arcs, meaning behind sentences and shared language of the experience were investigated using thematic analysis. Results: Four themes were identified: retelling of the traumatic event; social support; body image, the new normal; and rebirth and transformation. Accounts reflected the traumatic nature of the event with slowed downtime, attention to details and heightened recall.
Narrative Discourse

Narrative study
The following is an example of which type of qualitative study? Hip-Fracture Care in Rural Southwestern Ontario: A Study of Patient Transitions and Physiotherapy Handoffs Purpose: To examine information exchange by physiotherapists during care handoffs of patients with hip fractures in a rural health care setting. Methods: This study used observation and interviews of 11 networks of patients with hip fracture (n ¼ 11), family caregivers (n ¼ 8), and health care providers (n ¼ 24). Patients were followed from acute care through each subsequent care setting. Data were supplemented by health care records and policy documents. Results: Findings revealed that handoffs were less successful when information transfer was untimely or incomplete. Family caregivers experienced challenges in obtaining information required to facilitate the handoff, especially when direct contact with physiotherapists was not possible as a result of distance or other factors. Physiotherapists had to navigate multiple data sources to retrieve important information and managed information gaps in various ways. Information flow was often unidirectional and suggested no further clinical accountability for the discharging physiotherapist. Conclusions: Providing information in a structured and timely fashion facilitated physiotherapy handoffs. Inadequate handoffs compromised continuity of care, delayed progress in rehabilitation, and resulted in families' missing information of vital importance to their caregiving role. A multi-directional exchange of information is needed between patients, families, and health care providers across care settings. Johnson, H., Forbes, D., Egan, M. Y., Elliott, J., Stolee, P., & Chesworth, B. M. (2013). Hip-fracture care in rural southwestern Ontario: An ethnographic study of patient transitions and physiotherapy handoffs.
