הקליניקה של המחלקה לפסיכולוגיה בבר-אילן מובילה מחקרים פורצי-דרך בתחום הפסיכותרפיה מבוססת-ראיות (Evidence-Based Psychotherapy), ונחשבת לאחד המרכזים המחקריים המתקדמים והפוריים ביותר בארץ ובעולם. המחקר והטיפול בקליניקה מזינים את זה, כך שהממצאים המחקריים מתורגמים לעבודה טיפולית יעילה ואיכותית יותר, ובאותו הזמן ממש, העבודה הטיפולית מייצרת ומכווינה שאלות מחקריות חדשות.
המחקר העכשווי על תוצאות הפסיכותרפיה (Psychotherapy Outcome Research) מתמקד בזיהוי הגורמים המאפשרים לנבא מי מהמטופלים יפיק תועלת מהטיפול ובאיזה אופן. ממצאים עקביים מצביעים על כך שמעבר לטכניקה הספציפית, משתנים הקשורים לתהליכים תוך-טיפוליים (process variables) הם המנבאים החזקים ביותר לשינוי סימפטומטי. מחקרים עדכניים מדגישים מגוון רחב של משתנים התורמים להצלחה טיפולית ארוכת-טווח, ובניהם היכולת לנוע בין "מצבי עצמי" שונים וגמישות פסיכולוגית, עיבוד רגשי, חוזק הברית הטיפולית, סנכרון מטפל-מטופל, רפלקציה ומנטליזציה, ועוד.
פרופ' דנה אציל-סלונים, חברת סגל בכירה במחלקה לפסיכולוגיה ומנהלת המחקר בקליניקה, מרכזת ומובילה את המחקרים בתחום זה, לצד פרופ' יוגב קיוויתי, פרופ' רבקה תובל-משיח, פרופ' אשכול רפאלי, גב' אביגיל רוזנפלד גנזל, ד"ר יעל בר-שחר וד"ר מור קינן-בר.
