Impact of Patients Personality Traits and Doctor-Patient Alliance on the Effectiveness of Psychological Therapy, and Suggestion for Treatment

Abstract: Given the escalating prominence of mental health issues, enhancing the efficacy of psychological treatment has emerged as a pivotal concern. As an enduring psychological characteristic among individuals, patients' personality traits can influence their acceptance, engagement, and response to treatment procedures, thereby impacting treatment outcomes. Simultaneously, fostering a doctor-patient alliance founded on trust, respect, and collaboration also constitutes a crucial factor influencing treatment effectiveness. Consequently, exploring the interplay between patient personality traits and doctor-patient alliance is of paramount significance for optimizing psychotherapy practices and improving therapeutic outcomes. However, existing research exhibits gaps in understanding how patient personality traits and doctor-patient alliance contribute to treatment outcomes. The aim of this study was to investigate the impact of patient personality traits and doctor-patient alliance on the efficacy of psychotherapy, while proposing recommendations for enhancing the doctor-patient alliance. The methods employed in this study encompass a systematic review and comprehensive synthesis of existing literature, elucidating the present state of research, identifying research gaps, and delineating future research directions. The findings of various studies have consistently demonstrated that individuals with lower levels of neuroticism, extroversion, agreeableness, conscientiousness, and openness tended to exhibit more favorable treatment outcomes. Furthermore, the quality of therapeutic alliances significantly impacts psychotherapy effectiveness.
