Developing Complex Nursing Interventions Using Mixed Methods Research

Question

Tell whether the following statement is true or false:

Nursing intervention research refers to a distinctive process of developing, implementing, testing, and disseminating nursing interventions.

Answer

True

Nursing intervention research refers to a distinctive process of developing, implementing, testing, and disseminating nursing interventions—particularly complex interventions.

Nursing Intervention Research

Distinctive process
Developing, implementing, testing, and disseminating nursing interventions
Particularly complex interventions

Complex Intervention

Number of components
Number of outcomes targeted
Number and complexity of behaviors required
Time needed for the full intervention to be delivered

Framework Phases

Phase 1: Strong development efforts at the onset
Phase 2: Pilot tests of the intervention
Phase 3: Controlled trial to assess efficacy
Phase 4: Assess effectiveness of interventions in real-world clinical settings

Question

Tell whether the following statement is true or false:

Studies to assess effectiveness of interventions in real-world clinical settings (Phase 4) are common in nursing.

Answer

False

Studies to assess effectiveness of interventions in real-world clinical settings (Phase 4) are rare in nursing.

Framework

Idealized model
Process rarely linear
Mixed methods research

Question

Tell whether the following statement is true or false:

An important product during Phase 2 is a carefully conceived intervention theory from which the design of the intervention flows.

Answer

False

An important product during Phase 1 is a carefully conceived intervention theory from which the design of the intervention flows.

Phase 1

Conceptualization and in-depth understanding of the problem and the target population
Intervention theory
Resources for developing an evidence-based intervention and intervention strategies
Systematic reviews
Descriptive research
Consultation with experts
Discussion with team

Intervention Theory

Content
Dose and intensity
Timing
Outcomes to target and when to measure them
Setting
Agents
Mode of delivery
Individualization

Phase 2

Preliminary interventions tested
Simple quasi-experimental design
Pilots
Qualitative components
Recruitment and retention

Pilot Study

Feasibility of more rigorous testing
Lessons
Refine the intervention
Improve its acceptance and appeal
Enhance delivery

Question

Tell whether the following statement is true or false:

A mixed methods approach can strengthen the test of the intervention during the Phase 2 controlled trial.

Answer

False

A mixed methods approach can strengthen the test of the intervention during the Phase 3 controlled trial. The inclusion of qualitative components can shed light on intervention fidelity, variation in effects, clinical significance, and interpretive ambiguities.

Mixed Methods

Appropriate for all phases
Phase 1 QUAL has priority.
Phases 2 and 3 QUAN is usually dominant.
