Psychological disorders involve patterns of thoughts, feelings, or behaviors that cause distress, impairment, or increased risk of harm. This cheat sheet helps students compare major disorder categories and connect symptoms to possible therapeutic approaches. It is useful for studying abnormal psychology, clinical diagnosis, and treatment models in an introductory psychology course. The core ideas include using diagnostic criteria carefully, applying the biopsychosocial model, and distinguishing between psychotherapy and biomedical treatments. Students should know that symptoms must be evaluated by severity, duration, context, and impairment. Effective treatment often combines evidence-based therapy, social support, and medical care when appropriate.

Key Facts

A psychological disorder is usually identified when behavior, thoughts, or emotions are deviant, distressing, dysfunctional, or dangerous in a specific cultural context.
The biopsychosocial model explains disorders through biological factors + psychological factors + social and cultural factors.
Anxiety disorders involve excessive fear or worry, while obsessive-compulsive disorder involves obsessions plus compulsions that reduce anxiety temporarily.
Major depressive disorder commonly includes low mood or loss of interest plus symptoms such as sleep changes, appetite changes, fatigue, guilt, poor concentration, or suicidal thoughts.
Bipolar disorders involve mood episodes, with mania marked by elevated or irritable mood, increased energy, reduced need for sleep, and impulsive behavior.
Schizophrenia spectrum disorders may include positive symptoms such as hallucinations and delusions and negative symptoms such as flat affect or reduced motivation.
Cognitive behavioral therapy is based on the rule that changing maladaptive thoughts and behaviors can reduce emotional distress.
Treatment effectiveness is judged by symptom reduction, improved functioning, relapse prevention, and whether results are stronger than placebo or no-treatment comparison groups.

Vocabulary

DSM-5-TR: The Diagnostic and Statistical Manual of Mental Disorders used by clinicians to classify and diagnose psychological disorders.
Biopsychosocial model: An explanation of mental disorders that includes biological, psychological, and social influences.
Comorbidity: The presence of two or more disorders in the same person at the same time.
Cognitive behavioral therapy: A structured therapy that helps people identify distorted thoughts and replace harmful behavior patterns.
Exposure therapy: A behavioral treatment that gradually and safely introduces a feared object or situation to reduce avoidance and anxiety.
Psychopharmacology: The study and use of medications that affect mood, thinking, and behavior.

Common Mistakes to Avoid

Confusing normal stress with a disorder, because a diagnosis usually requires significant distress, impairment, duration, and context.
Treating one symptom as proof of a diagnosis, because disorders are diagnosed from patterns of symptoms rather than a single behavior.
Ignoring culture and environment, because behavior that seems unusual in one setting may be understandable or typical in another.
Assuming medication or therapy works the same for everyone, because treatment response depends on the disorder, severity, biology, support, and adherence.
Using labels as personal identities, because diagnostic labels describe clinical patterns and should not define a person's worth or character.

Practice Questions

3 A client rates anxiety as 9 out of 10 before exposure therapy and 4 out of 10 after several sessions. By how many points did the anxiety rating decrease?
4 Why is the biopsychosocial model more useful than explaining a psychological disorder using only brain chemistry?
