Psychology Research by Design: Questions, Hypotheses, Data, and Methods

This post is part of the continuing mini-series on RQ–RH–D–M across fields. Its purpose is to provide a compact, practical toolkit showing how research questions, research hypotheses or working propositions, data, and methodology can be aligned in one specific discipline.

Psychology is especially suitable for this kind of exercise because it naturally combines cognition, emotion, behavior, development, personality, relationships, mental health, social context and intervention effects. It also supports quantitative, qualitative and mixed methods designs, making it ideal for showing how the same psychological issue can be studied through experiments, psychometric scales, behavioral tasks, clinical or educational data, interviews, diaries and integrated designs.

In psychology, research is frequently based on frameworks such as cognitive theory, behavioral theory, social learning theory, self-determination theory, self-efficacy theory, attachment theory, personality frameworks, stress and coping models, mental health and wellbeing models and broader traditions in developmental, social, clinical and health psychology. These frameworks define constructs such as anxiety, self-esteem, coping, attachment, motivation, perceived stress, emotion regulation, wellbeing or psychological distress, which are then measured through validated scales, behavioral tasks, physiological indicators, experimental outcomes, interviews, diaries or multi-method psychological data.

Note: The entries in the Methodology column are intentionally general and indicative. They are meant to illustrate plausible methodological directions, not to exhaust the full range of possible methods, model variants or analytic choices available to the researcher. Researchers are not expected to apply all of the methodological tools listed in column Methodology in a single study. The entries are intended to indicate suitable methodological options or families of approaches from which the researcher selects those that best fit the research question, hypothesis, data, and design.

Psychology – quantitative research
