This course is designed as a continuation of the foundational concepts established in Semester 1, offering psychology students a comprehensive, advanced exploration of clinical psychology and psychotherapy. Building on prior knowledge, students will revisit the basic principles of psychological assessment, therapeutic practice, and developmental theory, which serve as the bedrock for more intricate study. The curriculum adopts a lifespan developmental approach, systematically examining mental disorders as they manifest from infancy through childhood, adolescence, adulthood, and into old age. By tracing how psychological conditions evolve across different stages, learners gain a nuanced appreciation of the interplay between biological, psychological, and social factors throughout the human life cycle. Central to the course is an in-depth investigation of the classification and diagnosis of mental disorders, utilising established diagnostic systems such as the DSM and ICD. Students will critically analyse diagnostic criteria, explore the complexities of differential diagnosis, and confront the challenges posed by overlapping symptomatology and comorbidities. The study of aetiology extends beyond surface-level explanations to encompass genetic, neurobiological, environmental, and psychosocial determinants, illustrating how multiple influences converge to shape the onset and progression of psychological disorders. Attention is paid to symptom patterns and the frequent occurrence of comorbid conditions, enabling students to appreciate the multifaceted nature of clinical presentations. The course further integrates epidemiological perspectives, encouraging students to examine prevalence rates, risk factors, and distribution patterns of mental health conditions across diverse populations and age groups. This epidemiological insight not only informs clinical practice but also underscores the importance of prevention and early intervention. Within this context, students are introduced to evidence-based psychotherapy approaches, including cognitive-behavioural, psychodynamic, humanistic, and integrative models. Each therapeutic method is presented with its theoretical foundations, technical components, and empirical support, fostering a critical understanding of how evidence guides intervention choices. In addition, the course delves into contemporary models of psychopathology, offering students a framework to comprehend both the onset and maintenance of mental disorders. Structured interventions are emphasised, with practical instruction on prevention, rehabilitation, and therapeutic techniques meant for various age groups and psychological conditions. Students will explore the application of these interventions in real-world settings, considering how individual, familial, and societal factors influence outcomes. A significant component of the curriculum is dedicated to ethical and culturally competent mental health care. Students are guided through the principles of scientific guidelines and clinical best practices, such as those outlined by the American Psychological Association and other global authorities, the Rehabilitation Council of India (RCI). Emphasis is placed on respecting cultural diversity, maintaining professional integrity, and adhering to ethical standards in diagnosis, intervention, and rehabilitation. By grounding clinical decisions in scientifically validated frameworks, the course ensures that future practitioners are equipped to deliver high-quality, responsible, and culturally sensitive care to individuals across the lifespan.
