The correct answer is problem-focused
Coping is mainly researched in relation to stress, being defined as “attempt or commitment to deal with external (environmental) or internal (one's own) demands perceived as overloading or exceeding one's resources.” (Folkman and Lazarus) .
Stressful events happen all the time in our lives: they are minor everyday setbacks, such as the long line at the bank, the traffic flow interrupted near home, the low grade of the child at school etc. Also stressful are positive events, such as the meeting, on carnival night, of a loving partner, the news of his son's approval in the entrance exam, an intense and ardent surrendering sexual intercourse, an unexpected compliment from the co-worker.
