Over the past two decades, the empirical literature has expanded substantially, yet critical gaps remain regarding intervention fidelity, population specificity, moderating variables, and long-term efficacy. This systematic review aims to map the evidence base of PPIs by synthesizing findings from meta-analyses, randomized controlled trials (RCTs), and recent empirical studies; identifying effectiveness across diverse populations; delineating methodological limitations; and articulating future research priorities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic search of PubMed, PsycINFO, Web of Science, and Scopus was conducted using Boolean search strategies.
