PEO

Qualitative questions evaluating experiences, meaningfulness

Population

Characteristics of a population (age, gender, ethnicity, etc) within a specific condition or set of circumstances. Example: Children
Exposure Medical, Behavioral, Occupational or Environmental factors that affect a population. Example:  Traffic-related Pollution
Outcome The result of said exposure on the population. Example:  ADHD diagnosis

 

 

SPIDER Question Framework (for Qualitative Reviews)

Sample A segment of a population group--allows for researchers to more deeply consider the sampled nature of Qualitative Research. Example:  Single Dads
Phenomena of Interest Certain behaviors, exposures, decisions, or experiences of interest. Example:  Father involvement programs
Design The theoretical framework used to determine what research methods are appropriate. Example:  focus groups
Evaluation What the researchers assess to determine the impact of the phenomena of interest. Example:  child development
Research Type Three types:  qualitative, quantitative, mixed methods Example:  Qualitative & mixed Methods

 

ECLIPSE Question Framework (for Policy and Administration Reviews)

Expectation The purpose of the query Example: Looking to improve rehabilitation times after ACL reconstruction surgery. What have others done?
Client Group Who does the query impact Example:  People with reconstructed ACLs
Location What is the setting of the impact Example:  Physical Therapy Clinics
Impact what is the change in the service, if any, which is being looked for? What would constitute success? How is this being measured? Example:  to reduce the number of PT visits post ACL reconstruction
Professionals what qualified staff or individuals are necessary  Example:  Physical Therapists
Service the kinds of services or programs being assessed Example:  exercises, stretches, cryotherapy

 

CIMO Question Framework (for administration, business, and management)

Context Which individuals, relationships, institutional settings, or wider systems are being studied? Example:  Long-Term care environments
Intervention The effects of what event, action, or activity are being studied? Example:  collective bargaining agreements
Mechanisms What are the mechanisms that explain the relationship between interventions and outcomes? Under what circumstances are these mechanisms activated or not activated? Example:  competitive wage and benefit packages
Outcomes What are the effects of the intervention? How will the outcomes be measured? What are the intended and unintended effects? Example:  decreased turnover in Nursing staff
