The theory of mood proposed by Thayer is examined in a sample of Spanish psychology students (N = 176). Results showed the existence of a circadian pattern of energy and tension levels, individual differences, such as gender, circadian type (morningness or eveningness), and some possible cross-cultural differences, though energy levels in American and Spanish samples were similar. Data also indicated differences in the assessment and interpretation of personal problems in relation to mood: according to energy level and mood, everyday problems and stress situations are interpreted in different ways. Finally, the results showed different manners in which people regulate mood. Implications for intervention and future research are discussed.
