A psychological network approach enables the study of psychological phenomena as networks of interacting elements using network psychometrics. This approach is gaining popularity across empirical psychology, including clinical and social domains. At the same time, a scientific debate has emerged about its added value and proper application. We contribute by providing an applied perspective on designing studies with a psychological network approach, based on best practices from previous research. We present a practical framework to support researchers and reduce potential criticism during study design. The framework consists of three iterative steps, illustrated with examples and practical considerations. First, researchers are recommended to evaluate their argumentation for adopting a psychological network approach and whether this is the best approach for their research aim. This approach is suitable for aims ranging from descriptive accounts of complex survey data to testing hypotheses about the network's structure. Second, careful selection of variables, informed by theory and prior research, is essential. Third, researchers should choose the most appropriate design and data type to answer their questions, as different designs yield different insights. Applying a psychological network approach following this framework can strengthen study design and advance empirical psychological research.
