Answer:
Qualitative research studies may inform physical therapists about all of the following:
1) Effect size: Qualitative research may provide insights into the experiences and perceptions of individuals, which can complement quantitative research focused on effect sizes.
2) Preferences: Qualitative research is particularly useful for understanding the preferences and perspectives of patients, which can be valuable information for physical therapists in tailoring treatment plans.
3) Expectancies: Qualitative research can help uncover patients' expectations and how these expectations influence their experiences and outcomes with physical therapy.
4) Values: Qualitative research often delves into the values, beliefs, and cultural factors that can impact patients' health-related decisions and experiences.
So, qualitative research can inform physical therapists about effect size, preferences, expectancies, and values.
