I still use my old parenting styles from before we had ingame scolding options a lot. Like when the father saw his teen son, who was going through a mean phase, bully a child on the sidealk, he gave the teen a handbuzzer shock (being a secret agent that knocked the boy out), then bought him a cheap computer so he could act out his phase in the anonymity of the internet and threatend to lock him inside his room if needed. This family was pretty much "ey, they'll outgrow it on their own".
I don't like how drastic a simple scolding can change a young sim's core values. The teen in question, when punished by my method, learned to stopp the behaviour because of consequences. But he didn't become any nicer, just better behaved for the sake of avoiding trouble. Left to his own he'd always reset to his old behaviour. I couldn't use the scolding mechanic on him, as that would have raised his conflict resolution and emotional control, which would have been out of character for him. The boy grew up neutral in all categories except for responsibility, where he scored the bonus trait just from going to school for one week and cleaning the house occassionally.
I'm on to the next family in rotation now, with a drunkard of a mother, an irresponsible rarely at home (cc) fairy father, a ruthless, ambitious worcaholic teen daughter and a daydreaming, idealistic, schoolskipping, painting teen daughter.
