Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by persistent, unwanted thoughts, urges, or images (obsessions) and repetitive behaviors or mental acts (compulsions) that an individual feels driven to perform to relieve anxiety or distress caused by these obsessions.| Simply Psychology
In psychology research, validity refers to the extent to which a test or measurement tool accurately measures what it's intended to measure. It ensures that the research findings are genuine and not due to extraneous factors. Validity can be categorized into different types, including construct validity (measuring the intended abstract trait), internal validity (ensuring causal conclusions), and external validity (generalizability of results to broader contexts).| Simply Psychology
