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

Purpose of review The ability to perform mental time travels and develop representations the past, present, future is one distinctive capacities human mind. Despite its pronounced consequences for motivation, cognition, affect, subjective well being, perspective (TP) has been outside mainstream psychiatry clinical psychology. We highlight role psychological-temporal phenomena in various disorders summarize current research on TP psychopathology. Recent findings Our ultimately comprised 21 articles, including 18 unique datasets. It revealed that persons with different psychiatric diagnoses (attention defict hyperactivity disorder (ADHD), alcohol dependence, anxiety disorders, depression, bipolar disorder, personality posttraumatic stress schizophrenia) display temporal profiles than control groups. also found marked associations between features symptom severity. effects specific TPs vary across some extent age groups, a consistent, widespread, nonspecific effect past-negative less balanced, inflexible profile. Summary Based review, biases are crucial factors development, while adaptive can serve as protective against disorders. Understanding cognitive-temporal processes enhance comprehension psychopathological conditions facilitate development temporality-focused interventions.
