There are several ways to determine whether someone may have a mental health condition. The most common is to consult with a healthcare provider, who will conduct a comprehensive evaluation of the individual's symptoms and behaviors. Other methods include asking questions about the individual's life history, such as past trauma or substance abuse; conducting an informal assessment of behavior patterns; or using screening tools such as the General Health Questionnaire (GHQ) or the Patient Health Questionnaire (PHQ). Additionally, it is important to pay attention to changes in mood and functioning over time and to look for signs of distress or impairment in social, work, or other areas of life.
