Research Variables and Hypotheses for Mindfulness-Based Interventions (MBIs) and ICU Nurses

Research Topic: Impact of Mindfulness-Based Interventions on Stress Reduction among Nurses in Intensive Care Units (ICUs)

Research Questions:

1. What are the perceived effects of mindfulness-based interventions (MBIs) on stress levels among nurses working in Intensive Care Units (ICUs)?
2. How do ICU nurses perceive the feasibility and acceptability of integrating MBIs into their daily routine?
3. What are the potential barriers and facilitators to successfully implementing MBIs for stress reduction in ICU nursing staff?

Independent Variable (Manipulated Variable):

• Mindfulness-Based Interventions (MBIs)

Dependent Variable (Outcome Variable):

• Depending on the research question:
  • Question 1: Perceived stress levels among ICU nurses (can be measured by a standardized stress scale)
  • Question 2: Feasibility and acceptability of MBIs (measured through surveys or interviews)
  • Question 3: Barriers and facilitators to implementing MBIs (identified through open-ended surveys or interviews)

Hypotheses: (Note that these are directional hypotheses, but you could also develop non-directional hypotheses)

Question 1:

• Research Hypothesis (H1): Nurses who participate in MBIs will report lower perceived stress levels compared to those who do not participate in MBIs.
• Null Hypothesis (H0): There will be no significant difference in perceived stress levels between nurses who participate in MBIs and those who do not.

Question 2: (These are not directional hypotheses because feasibility and acceptability are subjective experiences)

• Research Hypothesis (H1): ICU nurses will perceive MBIs as feasible and acceptable to integrate into their daily routines.
• Null Hypothesis (H0): ICU nurses will not perceive MBIs as feasible and acceptable to integrate into their daily routines.

Question 2: (These are not directional hypotheses because feasibility and acceptability are subjective experiences)

• Research Hypothesis (H1): ICU nurses will perceive MBIs as feasible and acceptable to integrate into their daily routines.
• Null Hypothesis (H0): ICU nurses will not perceive MBIs as feasible and acceptable to integrate into their daily routines.

Question 3: (This cannot be addressed with a hypothesis test, but will be explored through qualitative analysis)

This research will explore the barriers and facilitators to implementing MBIs for stress reduction in ICU nursing staff.
