A single-subject design was implemented with three participants diagnosed with health anxiety, encompassing baseline, intervention, and follow-up stages for each individual. Participants were selected through purposive sampling based on predefined inclusion and exclusion criteria. Given the nature of the single-subject design, control groups and randomization were not employed.

This study was conducted at the Sehat Psychological Clinic in Pakdasht using an ABA single-subject reversal design. The research procedure comprised baseline, intervention, and follow-up phases. During the intervention phase, an integrated protocol of Schema Therapy and Metacognitive Therapy was implemented across twelve 75-minute sessions. Health anxiety, quality of life, anxiety sensitivity, and intolerance of uncertainty were assessed using their respective standardized questionnaires. Given the single-subject nature of the study and the absence of a control group, no blinding procedures were utilized.»
