This case study examines the psychological and social aspects impacting the mental well-being of a 32-year-old unmarried woman. Based on comprehensive clinical assessment, Client D.A. was diagnosed with Major Depressive Disorder (MDD) using Structured Clinical Interview for DSM-5 (SCID-5), Minnesota Multiphasic Personality Inventory (MMPI-2), Rotter Incomplete Sentences Blank College Form (RISB), Draw-a-Person (DAP), clinical interviews, and behavioral observations. A multifaceted treatment plan was developed, combining cognitive behavioral therapy (CBT), interpersonal therapy (IPT), pharmacotherapy, mindfulness, and relaxation techniques. This study provides insights into her experiences of depression, social isolation, societal expectations, and self-esteem. Over the course of the treatment, Client D.A. demonstrated significant improvement in her depressive symptoms. Her negative thought patterns were effectively restructured through CBT and her interpersonal relationships improved with IPT. Additionally, pharmacotherapy stabilized her mood, while mindfulness techniques helped manage anxiety and stress. This case study highlights the complex interplay of factors influencing mental health and underscores the importance of culturally sensitive, personalized treatment approaches, as evidenced by Client D.A.’s increased social engagement, reduced loneliness, and improved well-being, with regular evaluations confirming sustained progress and the efficacy of the integrated treatment plan in promoting recovery.
