Chapter 13: The Descriptive Research Strategy

The descriptive research strategy serves as a foundational approach in psychological and behavioral research, focusing on the systematic examination of variables within their natural contexts without experimental manipulation. This chapter presents three primary methodological frameworks for conducting descriptive research, each with distinct applications and methodological considerations. Observational research encompasses naturalistic observation, where researchers document behavior in uncontrolled settings, participant observation, which involves the researcher engaging within the studied environment, and contrived observation, utilizing controlled settings that still preserve natural behavioral expression. Within observational designs, researchers employ specific quantification techniques including frequency counting to measure occurrence rates, duration recording to track temporal aspects of behavior, and interval sampling to capture behavior within defined time segments. Sampling strategies for observations involve time-based selection, event-based selection triggered by specific occurrences, and individual selection focused on particular participants. Content analysis and archival research extend descriptive methods to historical documents and existing records, enabling investigation of phenomena through secondary sources. Survey research represents another major descriptive approach, incorporating question formats ranging from open-ended inquiries that allow unrestricted responses to restricted questions with predetermined options, along with rating-scale instruments such as Likert scales that quantify subjective judgments. Survey administration encompasses multiple modalities including mail distribution, telephone interviews, internet-based platforms, and in-person administration, each presenting distinct advantages regarding response rates, cost efficiency, and data quality. The chapter addresses critical limitations inherent to descriptive methods, including nonresponse bias in surveys, interviewer bias effects, and concerns regarding generalizability across populations. Case study research, examining individual cases in depth, proves particularly valuable for investigating rare phenomena, documenting clinical interventions, and generating preliminary hypotheses for future investigation. The distinction between idiographic approaches focused on individual cases and nomothetic approaches seeking general patterns provides conceptual framework for understanding research goals and applicable descriptive methods within research design selection.
