Evidence indicates that borderline personality features emerging before adulthood can predict long\u2010term difficulties and may worsen over time. However, the role of assessment methods and the impact of psychological interventions on functional outcomes remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review and meta\u2010analysis of randomised controlled trials (RCTs) was conducted to evaluate the impact of psychological interventions on functioning in adolescents and young adults with BPD features. Four databases (PsycINFO, Medline, Embase and CINAHL) were searched up to June 2023.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      From 1859 identified studies, seven trials (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009657) met the inclusion criteria. Across studies, psychological interventions were associated with improvements in functioning from baseline to both post\u2010treatment and final follow\u2010up. However, when comparing specialised psychological interventions to generalist treatment as usual (TAU), differences were not statistically significant. Effect sizes were small at post\u2010treatment (SMD\u2009=\u20090.13, 95% CI\u2009=\u2009[\u22120.05, 0.31]) and remained small at final follow\u2010up (SMD\u2009=\u20090.12, 95% CI\u2009=\u2009[\u22120.08, 0.33]). Substantial heterogeneity was observed across studies, and risk of\u00a0bias was noted in several trials, with only two studies rated as low risk.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The findings suggest that both specialised psychological interventions and generalist interventions yield similar outcomes in terms of functional improvement.
