 The ATQ 30 consists of 30 negative statements and asks participants to indicate how often they experienced the negative thought during the course of the week on a scale of 1–5 (1=Low-High=5).This measure was created in response to Aaron T. Beck’s hypothesis that thinking in depressed populations tends to be negative.Example statements include "I'm worthless", "I've let people down", "I can't get started" and "My future is bleak".
