[Relationships between time perspective and time beliefs from adolescence to middle age].

This study attempted to clarify the age and sex differences in the perceptions of time perspective and time beliefs, and the relationships between them. A questionnaire consisted of Time Perspective Scale and Time Beliefs Scale was administered to 245 adolescents (range of age, 16-24), 46 young adults (25-39), and 150 middle aged persons (40-55). The main results were summarized as follows: (1) female adolescents showed a less sense of time perspective than the other age groups; (2) the same female adolescents expressed relatively higher degrees of Setsunashugi (the time belief of living only for the momentary pleasure); and (3) the Setsunashugi related with the lack of the sense of time perspective.
