Foundations of Applied Social Work Research

A research practicum prepares students to conduct empirical investigation rather than only consume the research of others, linking the logic of inquiry to the realities of field practice.

The Research–Practice Nexus

• Practice-informed research: questions arise from real encounters in practice settings.
• Research-informed practice: decisions guided by the best available evidence.
• Two-cycle model: inductive discovery (qualitative) meets deductive testing (quantitative).

Philosophical Paradigms

• Positivism: objective, measurable, cause–effect, quantitative.
• Interpretivism: meaning-making, subjective experience, qualitative.
• Pragmatism: methods chosen by the question, favouring mixed methods.
• Critical / social justice: research as advocacy for the structurally marginalised.

The Research Process

1. Problem identification and purpose formulation.
2. Literature review and theoretical framing.
3. Research design and question formulation.
4. Sampling and instrument development.
5. Data collection with ethical protection of participants.
6. Analysis, interpretation, and dissemination.

Qualitative Research and Fieldwork

Qualitative methods capture meaning, context, and process in naturalistic settings.

Key Designs

• Phenomenology (lived experience), case study (bounded system),
• Ethnography (cultural immersion), grounded theory (theory from data),
• narrative inquiry (stories), and participatory action research (PAR).

Data Collection and Sampling

• Interviews, focus groups, participant observation, and artefacts.
• Purposive sampling of information-rich cases; data to the point of saturation (no new themes).

Trustworthiness (Lincoln & Guba)

• Credibility — triangulation, member checks, prolonged engagement.
• Transferability — thick description.
• Dependability — audit trail, reflexivity journal.
• Confirmability — findings grounded in data, not researcher bias.

Fieldwork Conduct

Reflexivity (journaling one's own influence), supervision, and maintaining professional boundaries in agency fieldwork.

Quantitative Research and Mixed Methods

Quantitative research measures relationships between defined variables using structured instruments and statistical analysis.

Core Measurement Concepts

• Variables: independent, dependent, mediator, moderator.
• Scales: nominal, ordinal, interval, ratio.
• Reliability: test–retest, inter-rater, internal consistency (Cronbach's alpha).
• Validity: internal (causal) and external (generalisable).

Designs

• Experimental (RCT with random assignment), quasi-experimental (pre/post, non-equivalent groups),
• cross-sectional surveys, and longitudinal/panel designs for change over time.

Analysis Approaches

• Quantitative: t-tests, chi-square, ANOVA, correlation, regression; effect size and confidence intervals.
• Qualitative: thematic and content analysis, open/axial/selective coding.
• Mixed methods: concurrent or sequential; triangulation strengthens inference.

Reporting

Structure: abstract, introduction, literature, methods, findings, discussion, recommendations, references — with honest, transparent dissemination.

Ethics, Supervision and Practice Application

The research practicum is a site of intense ethical pressure; supervision is the safeguard.

Core Ethical Constraints

• Informed consent with vulnerable groups (children, people with disabilities, prisoners, trauma survivors).
• Confidentiality and anonymisation, data protection.
• Avoiding harm and re-traumatisation; cultural competence and fair recompense.
• Institutional research ethics (IRB) review.

Supervision and Mentorship

• Methodological, ethical, and design guidance by a research supervisor.
• Reflective journaling, peer debriefing, and iterative literature/data engagement.

Practice Application

• Disseminate findings back to the agency and community (feedback loop).
• Use results to inform intervention design and policy briefs.
• This closes the practice–research cycle: research feeds practice; practice refines research.

Final Review

1. Design an ethics protocol for a child-protection outcome study.
2. How do you adapt informed consent for a client with an intellectual disability?
