The Associations Between Deviation From the Balanced Time Perspective and Depression and Anxiety: The Moderator Role of Mindfulness in a Two-Wave Study
(Sage Publications inc, 2025) Altan-Atalay, Ayse; Ranjbar, Hamed Abdollahpour; Altintas, Seda
Deviation from the balanced time perspective (DBTP) refers to difficulties in switching between different time frames in a flexible way by considering the situational demands. DBTP is associated with higher levels of depression and anxiety. Mindfulness acts as a protective mechanism against depression and anxiety. The current study examined the moderator role of mindfulness in the relationship between DBTP and psychological distress. The participants were 243 university students (53.09% women) between ages 18 and 29 (M = 19.88, SD = 1.42) who answered self-report measures of time perspective, mindfulness, anxiety, and depression at two-time points with a five-week time interval. The results showed that the interaction between DBTP and mindfulness measured at time one could prospectively predict both anxiety and depression measured at time two. Mindfulness plays a significant moderating role in the relationship between DBTP and anxiety and depression. The data indicate that for individuals with low levels of DBTP, those with higher mindfulness experience significantly lower anxiety and depression compared to those with lower mindfulness. However, as DBTP increases, anxiety and depression levels in the high mindfulness group rise significantly, ultimately converging with those observed in the low mindfulness group. This indicates that while high mindfulness offers buffering effects against anxiety and depression, these effects diminish under increased DBTP.

Deviation From the Balanced Time Perspective and Depression and Anxiety Symptoms: the Mediating Roles of Cognitive-Behavioral Emotion Regulation in a Cross-Cultural Model
(Frontiers Media Sa, 2025) Ranjbar, Hamed Abdollahpour; Altan-Atalay, Ayse; Asgarabad, Mojtaba Habibi; Turan, Bulent; Eskin, Mehmet
Background Time perspective (TP) influences how individuals perceive and classify their past, present, and future, impacting their cognition, behavior, and psychological outcomes. Deviation from the balanced time perspective (DBTP) is associated with mental health problems (e.g., depression and anxiety). Emotion regulation (ER) encompasses cognitive and behavioral processes to regulate emotions, with maladaptive strategies like rumination and withdrawal linked to depression and anxiety. Despite extensive research on TP and ER, their joint impact, particularly in the context of depression and anxiety, and cultural differences remain underexplored.Method Participants (N = 513 Iranian, N = 470 Turkish) completed self-report questionnaires on time perspective, cognitive and behavioral ER, anxiety, and depression symptoms. A moderated mediation model was assessed, incorporating the exogenous variable of DBTP, with ER strategies as mediators, and endogenous variables of depressive and anxiety symptoms. The model accounted for cultural variations in the paths as a moderator.Results Significant associations were found between DBTP, ER strategies, depression, and anxiety symptoms. Mediation analyses revealed that both cognitive and behavioral ER strategies (except for adaptive behavioral ER strategies) significantly mediated the associations between DBTP and depression and anxiety. Additionally, multigroup analyses suggested that these mediating effects were consistent across Iranian and Turkish samples, with exceptions in adaptive cognitive ER strategies.Conclusion The study highlights the crucial role of TPs and ER strategies in predicting anxiety and depression symptoms, with notable cultural nuances. Specifically, maladaptive strategies exacerbate symptoms, while adaptive strategies mitigate them primarily in Iranian contexts. Cultural subtleties are discussed in detail.

Understanding the Immediate and Longitudinal Effects of Emotion Reactivity and Deviation From the Balanced Time Perspective on Symptoms of Depression and Anxiety: Latent Growth Curve Modeling
(Springer int Publ Ag, 2024) Ranjbar, Hamed Abdollahpour; Altan-Atalay, Ayse; Eskin, Mehmet
Emotion reactivity (ER) captures the depth, sensitivity, and endurance of our emotional reactions, while deviation from a balanced time perspective (DBTP) characterizes our inflexibility and rigidity in adhering to specific time frames. This study investigates how ER and DBTP might predict the symptoms of depression and anxiety and DBTP's mediating role between ER and the symptoms of anxiety and depression in a three-wave longitudinal investigation. Data from 148 university students (82 males, 55.4%) with the age range of 18-29 (Mage = 19.92, SDage = 1.36) were collected at three time intervals using Emotion Reactivity Scale, Zimbardo Time Perspective Inventory, Future Negative subscale, Generalized Anxiety Disorder-7, and Patient Health Questionnaire-9. The study utilized latent growth curve modeling (LGCM) within a structural equation modeling framework. Results showed that greater DBTP at baseline predicted increased anxiety and depression symptoms and longitudinally reduced anxiety symptoms. The mediation model clarified that, initially, DBTP mediated the relationship between ER and anxiety/depression symptoms; however, over time, DBTP functioned as a suppressor of anxiety symptoms. This study establishes DBTP's predictive and dynamic significance for anxiety and depression, unveiling its mediating role in the interplay with emotional reactivity. These findings can inform tailored therapies addressing ER and temporal biases in this population.
