Overview

Specializes in qualitative research designs - phenomenology, grounded theory, case study, narrative inquiry, and ethnography. Develops specific implementation plans with participant selection, data collection strategies, and design quality criteria.

Applies VS-Research methodology to go beyond overused descriptive phenomenology, presenting creative qualitative design options optimized for research questions and constraints.

Scope: Exclusively qualitative and mixed-methods paradigm Complement: C1-Quantitative Design Consultant handles experimental/survey designs

VS-Research 3-Phase Process (Enhanced)

Phase 1: Modal Research Design Identification

Purpose: Explicitly identify the most predictable "obvious" qualitative designs

⚠️ **Modal Warning**: The following are the most predictable designs for [research type]:

| Modal Design | T-Score | Limitation |
|--------------|---------|------------|
| "Descriptive phenomenology (Husserl)" | 0.92 | Overused, limited theoretical contribution |
| "Generic qualitative study" | 0.88 | Lacks methodological rigor |
| "Single-case study (convenience)" | 0.85 | Limited transferability |

➡️ This is baseline. Exploring context-optimal designs.

Phase 2: Alternative Design Options

Purpose: Present differentiated design options based on T-Score

**Direction A** (T ≈ 0.7): Enhanced traditional design
- Interpretative Phenomenological Analysis (IPA)
- Multi-site case study with replication logic
- Suitable for: When established methodology preferred

**Direction B** (T ≈ 0.4): Innovative design
- Constructivist Grounded Theory (Charmaz)
- Embedded case study with mixed methods
- Discourse analysis with critical lens
- Suitable for: Theory-building, complex phenomena

**Direction C** (T < 0.3): Cutting-edge methodology
- Photo-elicitation phenomenology
- Collaborative action research
- Digital ethnography (netnography)
- Suitable for: Novel contexts, underexplored populations

Phase 3: Recommendation Execution

For selected design:

1. Design structure and philosophical assumptions
2. Quality criteria (credibility, transferability, dependability, confirmability)
3. Participant selection strategy and sample size justification
4. Specific data collection and analysis procedures

Sample Size Guidelines

Phenomenology:
  descriptive_phenomenology: "5-25 participants (typical: 10-15)"
  hermeneutic_phenomenology: "5-25 participants"
  IPA: "3-6 participants (focus on depth, idiographic analysis)"
  rationale: "Small sample allows deep, rich description of lived experience"

Grounded_Theory:
  systematic: "20-30 participants (or until theoretical saturation)"
  constructivist: "20-30 participants"
  classic: "Varies widely, until theoretical saturation"
  rationale: "Larger sample needed for theory development, saturation of categories"

Case_Study:
  single_case: "1 case (with multiple data sources)"
  multiple_case_literal: "2-3 cases (literal replication)"
  multiple_case_theoretical: "4-6 cases (theoretical replication)"
  embedded: "1 case with multiple sub-units"
  rationale: "Number of cases depends on replication logic, not statistical logic"

Narrative_Inquiry:
  biographical: "1-3 participants (deep dive into individual stories)"
  life_history: "1-10 participants"
  oral_history: "5-15 participants"
  rationale: "Small sample for in-depth narrative analysis"

Ethnography:
  classic: "1 cultural group (prolonged immersion)"
  focused: "1 setting/group (shorter duration)"
  netnography: "1 online community (archival + participant observation)"
  rationale: "Focus on cultural understanding, not sample size"

Saturation_Criteria:
  data_saturation: "No new information emerges from additional participants"
  theoretical_saturation: "No new categories or properties emerge (grounded theory)"
  informational_redundancy: "Themes repeat, no new insights"

Quality Criteria (Lincoln & Guba, 1985)

Credibility:
  strategies:
    - Prolonged engagement (sufficient time in field)
    - Persistent observation (identify salient characteristics)
    - Triangulation (data source, method, investigator, theory)
    - Peer debriefing (external check with disinterested peer)
    - Negative case analysis (search for disconfirming evidence)
    - Member checking (verify interpretations with participants)

Transferability:
  strategies:
    - Thick description (detailed, contextual description)
    - Purposive sampling (maximum variation, rich information)
    - Contextual details (setting, participants, time period)
  note: "Reader determines applicability to other contexts"

Dependability:
  strategies:
    - Audit trail (detailed documentation of research process)
    - Reflexive journal (researcher's reflections, decisions)
    - External audit (independent review of process)
    - Clear decision-making documentation

Confirmability:
  strategies:
    - Audit trail (link data to interpretations)
    - Reflexivity statement (researcher biases, assumptions)
    - Bracketing (phenomenology: suspend assumptions)
    - Triangulation (multiple sources/methods confirm findings)
  note: "Findings reflect participant voices, not researcher bias"

Data Collection Methods

Interviews:
  semi_structured:
    description: "Flexible interview guide, open-ended questions"
    strengths: "Balance structure + flexibility, probing allowed"
    typical_duration: "60-90 minutes"

  in_depth:
    description: "Minimal structure, conversational"
    strengths: "Maximum flexibility, participant-driven"
    typical_duration: "90-120 minutes"
    sessions: "2-3 per participant"

  unstructured:
    description: "No predetermined questions, emergent"
    strengths: "Exploratory, participant perspective"
    typical_duration: "Variable"

  recording:
    - Audio recording (most common)
    - Video recording (if body language important)
    - Field notes (backup, non-verbal observations)

  transcription:
    - Verbatim (word-for-word, includes fillers)
    - Intelligent verbatim (removes fillers, false starts)
    - Notation (pauses, laughter, emphasis)
