Diagnose and treat mental, emotional, and behavioural disorders
Integrates scientific research, psychological theory, and clinical knowledge to understand and alleviate psychological distress
Sits within a broad group of mental health professionals including psychiatrists, therapists, counsellors, social workers, etc
Clinical psychologists often specialise in different areas, such as child and adolescent psychology, forensic psychology, neuropsychology, or health psychology.
Work settings include private practice, hospitals, community mental health centers, rehabilitation facilities, and academic institutions.
It focuses on psychological therapy, assessment, and behavioural interventions
Assess and diagnose psychological conditions using clinical interviews, psychometric assessments, and observation.
Develop and implement evidence-based treatments tailored to individual needs.
Promote mental health and well-being through therapy, psychoeducation, and preventative interventions.
Conduct research to improve psychological treatments and understand mental health disorders.
Provide consultation and supervision to other professionals in clinical and academic settings.
Use standardized psychological tools, such as MMPI (Minnesota Multiphasic Personality Inventory), WAIS (Wechsler Adult Intelligence Scale), and Beck Depression Inventory.
Collaborate with other healthcare professionals to provide holistic care.
Clinical psychologists support individuals across various psychological and life challenges. Common reasons for seeking therapy include:

Diagnostic and Statistical Manual of Mental Disorders
The DSM-5 (latest version) provides a biopsychosocial approach to diagnosing mental disorders.
Divides disorders into 18 different classes (e.g., neurodevelopmental disorders, schizophrenia spectrum, mood disorders, anxiety disorders, etc.).
Contains over 300 diagnoses with clearly defined criteria for diagnosis.
Sets thresholds and rules for meeting diagnostic criteria (e.g., symptom duration, impact on daily functioning).
Used by psychologists, psychiatrists, and mental health professionals worldwide.
Two people with the same diagnosis can experience very different symptoms.
Example: Two individuals with depression—one might have insomnia and anxiety, while another experiences lethargy and social withdrawal.
If a person has one disorder, they are more likely to have another.
Example: Major Depressive Disorder (MDD) frequently co-occurs with Anxiety Disorders.
Four Foundational Models of Psychological Therapy
Psychodynamic (Unconscious processes, early experiences)
Biological (Brain structure, genetics, neurotransmitters)
Behavioural (Learned behaviours, conditioning)
Cognitive-Behavioural (CBT) (Thought patterns influencing behaviour)
Rooted in Freudian theory but evolved significantly.
“Two things you need to know about Feud. One is he was wrong, and the second is that he’s dead.:
Explores unconscious processes, early childhood experiences, and internal conflicts.
Unconscious Processes
Behavior, thoughts, and emotions are shaped by unconscious drives & motivations.
Therapy seeks to bring these hidden elements to awareness.
Early Childhood Experiences
Personality & relationship patterns are shaped by early experiences.
Unresolved past conflicts can manifest in current behaviors and emotional difficulties.
Internal Conflicts and Defense Mechanisms
Psychological distress stems from inner conflicts between unconscious desires & societal expectations.
Defense mechanisms (e.g., repression, denial, projection) help manage distress but may become maladaptive.
Therapy examines whether these defenses are helpful or hindering.
Transference and Countertransference
Transference: Client projects feelings from past relationships onto the therapist.
Countertransference: Therapist's emotional reaction to the client.
Exploring these dynamics reveals relational patterns and emotional blind spots.
Therapeutic Relationship
The therapist-client relationship serves as a microcosm for understanding a client’s emotional world.
Techniques
Free association (express thoughts without censorship)
Interpretation (analyzing themes in speech and behavior)
Dream analysis (examining unconscious symbolism)
Mental disorders have biological causes (e.g., brain structure, neurotransmitters, genetics).
Neurological & neurochemical: Imbalances in dopamine, serotonin, etc.
Genetic & epigenetic: Inherited vulnerabilities, environmental triggers.
Endocrine system: Thyroid, stress hormones affecting mood.
Medication: Antidepressants, anxiolytics, antipsychotics, mood stabilizers.
Other interventions: ECT (electroconvulsive therapy), TMS (transcranial magnetic stimulation), VNS (vagus nerve stimulation), DBS (deep brain stimulation), neurofeedback
ect and tms helps with severe depression that nothing else seems to work for
Lifestyle factors: Diet, sleep, and exercise significantly impact mental health.
biological — physical health and genetics → medical interventions
psychological and social factors interpret more broadly and inform complementary strategies
Focuses on observable behaviors and how they are learned through conditioning.
Classical Conditioning (Pavlov): Learning through association.
Operant Conditioning (Skinner): Behavior shaped by rewards and punishments.
Social Learning (Bandura): Observing and imitating others.
Systematic Desensitization: Gradual exposure for phobias.
Token Economies: Reward-based systems for behavior change.
cognitions (thoughts) are also important — dysfunctional thinking leads to dysfunctional emotions or behaviours
identify and challenge distorted or irrational thoughts and beliefs, and replace them with more realistic, positive ones
Focuses on how thoughts influence emotions and behaviors.
Developed into Cognitive-Behavioral Therapy (CBT), which combines cognitive and behavioral strategies.
techniques include cognitive restructuring, problem-solving, and skills training
explain the rationale for the importance of thoughts — their relationship with feelings and behaviours
Cognitive Restructuring:
Identifying and challenging distorted thoughts.
Example: Changing “I’m a failure” to “I made a mistake, but I can improve.”
ABC model
“A”ctivating event
“B”eliefs or thoughts about that event
“C”onsequences — that is, your emotional, physiological and behavioural consequences
Example
**Activating event—**Partner not home from work an hour later than usual – they are rarely late and there has been no call or text
**Belief—**Stuck in a meeting → **Consequences—**Maybe a bit annoyed;Maybe a bit empathetic; Maybe a bit happy; Delay dinner
**Belief—**In a serious accident → **Consequences—**Worried; Increased heart rate; Call the hospital/police
**Belief—**Cheating on you → **Consequences—**Angry/upset; Heart races; Short of breath; Panic/anxiety; Destroy their stuff
How do we know which therapies work?
Must be evidences based
Must use APA guidelines
Treatments must be evidence-based to be considered effective.
3 criteria:
at least two independent randomised controlled trials (RCTs) that indicate that the intervention is useful in treating a particular presenting problem
the active treatment must be better than either a placebo condition or an alternative active reaction
the rct must be competently carried out
should be registered on a clinical trials register
full protocol for the trial should be outlined
recruitment procedures plus inclusion/exclusion criteria specified
random assignment to conditions (conditions clearly described - active intervention, a placebo or a wait list control)
assessment before and after the intervention (plus follow-ups)
enough participants to be able to detect a difference between conditions if such a difference exists – adequately powered
Gold standard for research.
Includes pre/post-assessment, randomization, control groups.
Example: Comparing CBT for anxiety vs. medication.
