Final answer:
The humanistic approach enhances psychological health by promoting conditions for self-actualization, and a study with strict screening and random assignment for depression treatment is likely a randomized control trial.
Step-by-step explanation:
According to the humanistic approach, psychological health is enhanced by fostering conditions that promote the growth potential of healthy individuals. Humanistic psychologists like Abraham Maslow and Carl Rogers emphasized that psychological health is not just about treating illness, but about nurturing well-being and self-actualization—the achievement of our fullest potential. This includes being open, creative, loving, spontaneous, and accepting of oneself.
When a researcher conducts a study on the effectiveness of treatment for depression that involves strict screening and random assignment, they are likely conducting a randomized control trial (RCT). This type of study is considered a gold standard in health psychology, as it can provide robust evidence for the efficacy of an intervention by comparing treatment effects in the experimentally-treated group against a control group that does not receive the intervention.
