Final answer:
The statement about third-generation behavior therapies is true, focusing on themes that include mindfulness and acceptance. The MMPI utilizes true/false questions for personality assessment. The temperance movement was indeed linked to responses to urbanization and immigration.
Step-by-step explanation:
The statement that third-generation behavior therapies center around five interrelated core themes is true. Third-generation behavior therapies, which include dialectical behavior therapy (DBT), acceptance and commitment therapy (ACT), and mindfulness-based cognitive therapy (MBCT), are known for focusing on mindfulness, acceptance, cognitive defusion, dialectics, values, and relationship, among other concepts. These approaches are often used within clinical psychology to address a wide range of psychological issues and are considered part of the evolution of cognitive-behavioral therapy, incorporating new strategies and a broadened focus to enhance therapeutic outcomes.
As for the Minnesota Multiphasic Personality Inventory (MMPI), it is indeed a personality assessment that employs a series of true/false questions, making option 'a' the correct answer. The MMPI is widely used in clinical settings to help diagnose mental disorders and assess personality structure.
The temperance movement's connection to new social conditions such as increasing urbanization and immigration is also true. The movement, which campaigned for moderation or complete abstinence in alcohol consumption, was partly a response to social challenges and changes brought on by urbanization and increased immigration during the 19th and early 20th centuries.
