Literature Review

Skill: Literature Review

Systematic literature search, synthesis, gap identification, and narrative construction for academic research.

Metadata

Overview

Literature review is foundational to academic research. This skill provides structured workflows for systematic searching, critical synthesis, and gap identification—transforming scattered sources into coherent scholarly narratives.

Core Competencies

1. Systematic Search - Reproducible, comprehensive search strategies
2. Critical Appraisal - Quality assessment of sources
3. Synthesis - Thematic integration across sources
4. Gap Identification - Locating research opportunities
5. Narrative Construction - Weaving sources into argument

Module 1: Systematic Search Strategy

The PICO(S) Framework

For empirical research questions:

Database Selection

Search String Construction

Boolean operators:

("artificial intelligence" OR "AI" OR "machine learning")
AND
("adoption" OR "acceptance" OR "intention")
AND
("UTAUT" OR "TAM" OR "technology acceptance")

Truncation and wildcards:

• adopt* → adoption, adopting, adopter
• behavio?r → behavior, behaviour

Search Protocol Template

## Search Protocol

**Research Question**: [Your RQ]
**Date Conducted**: [Date]
**Databases Searched**: [List]

### Search Terms
- Primary: [terms]
- Secondary: [terms]
- Exclusions: [terms with NOT]

### Inclusion Criteria
- Published: [date range]
- Language: [languages]
- Study type: [empirical, theoretical, etc.]
- Peer-reviewed: [yes/no]

### Exclusion Criteria
- [List exclusions]

### Results
| Database | Initial Hits | After Dedup | After Title Screen | After Abstract Screen | Final |
|----------|--------------|-------------|--------------------|-----------------------|-------|

Module 2: Source Management

The Funnel Process

Initial Search Results (hundreds)
        ↓ Title screening
Potentially Relevant (~50-100)
        ↓ Abstract screening
Candidates for Full-Text (~30-50)
        ↓ Full-text review
Included Sources (~15-30)
        ↓ Backward/forward citation
Final Corpus (~20-40)

Screening Criteria

Quick reject (title/abstract):

• Wrong population
• Wrong intervention
• Wrong outcome
• Non-empirical (if seeking empirical)
• Wrong language
• Duplicate

Full-text assessment:

• Methodological rigor
• Relevance to research question
• Contribution to synthesis

Citation Tracking

Backward citation (reference mining):

• Review reference lists of key papers
• Find foundational works
• Identify theoretical ancestry

Forward citation (cited by):

• Use Google Scholar "Cited by"
• Find recent developments
• Identify methodological improvements

Module 3: Critical Appraisal

Quality Assessment Dimensions

Study Type Checklists

Quantitative survey studies:

• Sample size adequate (power analysis?)
• Response rate reported
• Validated instruments used
• Reliability reported (Cronbach's α)
• Common method bias addressed
• Appropriate statistical analysis

Qualitative studies:

• Sampling strategy justified
• Data saturation discussed
• Researcher positionality stated
• Coding process transparent
• Member checking or triangulation

SEM/CFA studies:

• Model fit indices reported (CFI, RMSEA, SRMR)
• Convergent validity (AVE ≥ .50)
• Discriminant validity (HTMT < .85)
• Sample size adequate (N ≥ 200 preferred)

Module 4: Synthesis Strategies

Thematic Synthesis

1. Code individual sources - Key concepts, findings, methods
2. Group codes into themes - Patterns across sources
3. Develop analytical narrative - What themes mean together

Example themes for AIRS research:

• Trust and reliance
• Value perception
• Effort-benefit trade-offs
• Social and organizational factors

Comparative Matrix

Theoretical Integration

Identifying theoretical tensions:

• Where do theories contradict?
• What boundary conditions apply?
• How can conflicts be resolved?

Building theoretical contribution:

• What's missing from current theories?
• How does your work extend understanding?
• What new constructs are needed?

Module 5: Gap Identification

Types of Research Gaps

Gap Articulation Template

## Research Gap

**What we know**: [Summary of existing knowledge]

**What we don't know**: [The gap]

**Why it matters**: [Significance of filling gap]

**How this study addresses it**: [Your contribution]

Module 6: Writing the Literature Review

Structure Options

Chronological:

• Best for: Tracing evolution of a concept
• Risk: Can become mere historical summary

Thematic:

• Best for: Synthesizing diverse perspectives
• Risk: May obscure temporal development

Methodological:

• Best for: Evaluating research approaches
• Risk: Can be dry, less engaging

Theoretical:

• Best for: Comparing frameworks
• Risk: Requires deep theory knowledge

The Funnel Structure

Broad context (the problem space)
    ↓
Theoretical foundations (key theories)
    ↓
Prior empirical work (what's been studied)
    ↓
Gap and contribution (what's missing → your work)

Synthesis vs. Summary

❌ Summary (weak):

"Smith (2020) found X. Jones (2021) found Y. Brown (2022) found Z."

✅ Synthesis (strong):

"While early studies emphasized X (Smith, 2020), subsequent research revealed the moderating role of Y (Jones, 2021), leading to more nuanced frameworks that integrate both factors (Brown, 2022)."
