I’ve had the experience of accompanying many people to such assessments. Those who haven’t gone through this ordeal probably have fantasies about a wise and understanding therapist carefully listening to every word about why you are in such distress and responding with empathy about common human emotions. Maybe they see a motherly or fatherly image handing you a tissue or giving you a comforting pat on the back and validating you’re feelings of despair and hopelessness in a stressful and complicated world. The unknowing public also might imagine that the therapist would help you immediately connect to a support network of caring family and friends and a safe comfortable space to chill out. But, it’s usually nothing like that. I’ve found it to be more like undergoing a lie detector test which also are not accurate. But, they’re searching for magic suicidal words showing a “plan”, “means”, “how soon” and “have you attempted before“? This stranger with credentials and keys who often remains emotionally neutral can keep asking you question after personal intrusive question with little empathy until you hit the jackpot to “get helped” by answering them correctly or not (which as you say accurately predicts nothing). And for many this ordeal happens after being handcuffed and transported by the police to an unpleasant office where the police wait somewhere nearby to complete your confinement in a locked facility “when necessary“. If you happen to not answer the questions in ways to get yourself locked up, you are left alone to receive no therapy or compassion or resources at all and may have no way to get home. Your consolation prize might be a referral with a long waiting list which you may or may not want or be eligible for to meet your needs. No wonder we have more people dying from suicide than homicide each year.
