Time Perspective, Working Memory, and Depression in Non-Clinical Samples: Is There a Link?

Area of Science:

• Psychology
• Cognitive Science

Background:

• Non-clinical depression significantly affects college students, with up to 30% experiencing major depressive episodes.
• The Zimbardo and Boyd (1999) time perspective model suggests time perception influences emotions, judgments, and decision-making.

Purpose of the Study:

• To investigate the role of time perspectives, hope, rumination, and working memory in college student depression.
• To compare these influences between currently enrolled college students and non-college participants.

Main Methods:

• Participants (college students and non-college individuals) completed validated scales: Center for Epidemiologic Studies Depression Scale, Zimbardo Time Perspective Inventory, Adult Hope Scale, Rumination Reflection Questionnaire, and Automated Working Memory Assessment.
• Linear regression analysis was employed to identify predictive factors for depressive symptoms.

Main Results:

• For college students, rumination and negative past time perspectives significantly predicted depressive symptoms.
• In non-college students, rumination, present fatalism, hope agency, and verbal working memory predicted depressive symptoms.

Conclusions:

• Rumination is a key factor in depression symptomology across different groups.
• Incorporating time perspective measures into cognitive depression models and treatments may enhance effectiveness.
