Resumé	A longitudinal structured interview applies a fixed, standardised interview schedule to the same participants at two or more points in time. By holding the instrument constant across waves, the method enables genuine within-person change to be measured, trends to be tracked, and causal sequences to be examined with far greater confidence than a single cross-sectional interview can provide. It is widely used in panel studies, cohort research, and programme evaluations.	A structured interview is a data collection technique in which every participant is asked exactly the same pre-specified questions in the same order, using standardized wording. Because the interview schedule is fixed, responses across participants are directly comparable, enabling quantitative aggregation and statistical analysis. It sits at the most standardized end of the interview continuum, between the self-administered questionnaire and the semi-structured interview.
