Time matters for mental health: a systematic review of quantitative studies on time perspective in psychiatric populations.

PURPOSE OF REVIEW: The ability to perform mental time travels and to develop representations of the past, the present, and the future is one of the distinctive capacities of the human mind. Despite its pronounced consequences for motivation, cognition, affect, and subjective well being, time perspective (TP) has been outside mainstream psychiatry and clinical psychology. We highlight the role of psychological-temporal phenomena in various disorders and summarize the current research on TP and psychopathology. RECENT FINDINGS: Our review 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 disorders, posttraumatic stress disorder, schizophrenia) display different temporal profiles than control groups. We also found marked associations between temporal features and psychiatric symptom severity. The effects of specific TPs vary across different psychiatric diagnoses and to some extent between various age groups, with a consistent, widespread, and nonspecific effect of past-negative and less balanced, inflexible TP profile. SUMMARY: Based on the review, TP biases are crucial factors in symptom development, while adaptive temporal profiles can serve as protective features against mental disorders. Understanding cognitive-temporal processes can enhance comprehension of psychopathological conditions and facilitate the development of temporality-focused clinical interventions.

Why do owls have it worse? Mediating role of self-perceptions in the links between diurnal preference and features of mental health.

Recent research provides evidence for the negative social perceptions of evening chronotypes and their consequences on mental health. However, there is a lack of studies indicating whether these negative, socially shared beliefs may become internalized in negative self-perceptions of evening-types (E-types). The present article provides a seminal empirical analysis of the role of self-liking and self-competence in the associations between chronotype and both depressiveness and well-being. In the first part of the study, the participants completed the Composite Scale of Morningness. On the basis of the chronotype cut-off criteria for Composite Scale of Morningness distribution, 100 individuals were classified as morning-types (M-types) and 66 individuals as E-types. Therefore, 166 participants (80 women and 86 men) aged 18-36 years (M ± SD: 29.27 ± 4.81 years) took part in the second part of the study, and completed questionnaires measuring self-liking, self-competence, life satisfaction, positive and negative affect, and depressiveness. Results show that E-types scored lower in self-liking, self-competence and subjective well-being, and higher in depressive symptoms than M-types. Controlling for age and gender, we obtained significant mediation effects, showing that the relationship between chronotype and subjective well-being might stem from the lower levels of self-liking and self-competence among E-types, and that the relationship between chronotype and depressive symptoms might stem from the lower level of self-liking among E-types. Our results suggest that self-liking and self-competence are important antecedents of lower well-being and higher depressiveness reported by E-types. Socially shared stereotypes of M-types and E-types can be internalized by the extreme chronotypes, which may significantly affect their psychological health.

Blame it on the "night owls": Perceived discrimination partly mediates the effects of morningness-eveningness on positive and negative affect.

The well-established effects of evening preference on diminished well-being and poorer mental health are usually explained in terms of common genetic bases of eveningness and negative emotionality and/or the discrepancy between biological and social clocks, experienced far more frequently by the Evening-types. However, recent studies provide evidence for the negative stereotyping of evening chronotypes which may lead to unexpectedly pronounced social stigma and its consequences. The present article provides a seminal empirical analysis of the role of perceived chronotype-related discrimination in the association between morningness-eveningness and both positive affect and negative affect. The study was conducted on a gender-balanced sample of 768 individuals aged between 18 and 56 years who filled measures of morningness-eveningness, positive and negative affect, as well as a modified version of the Perceived Devaluation Discrimination scale, tentatively labeled Perceived Chronotype-Related Discrimination scale (https://osf.io/urs8x/), developed to measure the sense of chronotype-based discrimination. Conducted analyses provided evidence for a positive association between eveningness and perceived discrimination. Moreover, perceived discrimination partly mediated the associations between morningness-eveningness and both positive affect and negative affect, explaining 18% and 29% of these effects, respectively. Hence, our results provide initial evidence for yet another mechanism through which chronotype may impact emotional functioning, namely the experience of chronotype-based stigmatisation.

Time will tell: Associations between unbalanced time perspectives and symptom severity in individuals with schizophrenia spectrum disorders.

Patients with schizophrenia spectrum disorder (SSD) experience disrupted temporality on the immediate timescale. However, insufficient information is available for longer time frames, and the interaction of temporal perspectives with the clinical manifestations of SSD is unknown. We explored the association between unbalanced time perspectives and symptom severity. Thirty-seven Italian mental health services participating in the DiAPAson project recruited 620 patients with DSM-5 SSD (68 % males, mean age = 41.3 ± 9.5 years). Time perspective biases were measured using the Deviation from the Balanced Time Perspective-revisited (DBTP-r) indicator, based on Zimbardo Time Perspective Inventory (ZTPI) scores. Psychiatric symptoms were assessed using the Brief Psychiatric Rating Scale (BPRS) and Brief Negative Symptoms Scale (BNSS). Preliminary analyses examined the associations between ZTPI/DBTP-r and BPRS/BNSS total scores. In secondary analyses, we first tested the associations between the ZTPI/DBTP-r and BPRS/BNSS subscales and then compared ZTPI differences between patients with and without hallucinations, delusions, and conceptual disorganisation. Statistical significance was set at Holm-Bonferroni corrected p < 0.05. Low-to-moderate positive correlations were found between the DBTP-r and BPRS/BNSS total scores (r = 0.29/0.22). The strongest associations were between DBTP-r/ZTPI_Past-Negative and anxiety/depression (r = 0.34/0.36), followed by DBTP-r/ZTPI_Present-Fatalistic with thought disturbances (r = 0.22/0.20). DBTP-r was associated with BNSS anhedonia and avolition (r = 0.21/0.24). DBTP-r was higher in patients with hallucinations (ES = 0.391) and conceptual disorganisation (ES = 0.397) than in those without these symptoms. Unbalanced time perspective was positively associated with the severity of primary and secondary SSD features. These findings provide a rationale for empirical tests focused on balancing time perspectives in patients with SSD.

A conditional process model of perfectionism, goal-realization, and post-competition mood.

Research has recently begun to examine the relationship between multidimensional perfectionism and athletes' post-competition mood. However, to date, there have been few attempts to examine the interaction between dimensions of perfectionism or model possible explanatory processes. To address these limitations, in the current study we tested a novel conditional process model whereby the relationship between perfectionistic strivings and post-competition affect was mediated by the degree to which goals were considered to have been met (goal-realization) and that this indirect effect was, in turn, moderated by levels of perfectionistic concerns. We tested this model in a sample of 251 athletes who took part in a "Runmageddon" event - a cross-country obstacle race. Athletes completed measures of perfectionism (perfectionistic strivings and perfectionistic concerns) before the race and measures of goal-realization and mood (tense arousal, energetic arousal, and hedonic tone) between 24 and 48 h after the race. Analyses revealed that perfectionistic strivings were indirectly linked to a more unpleasant post-competition mood (higher tense arousal and lower hedonic tone) via perceptions of lower goal-realization. In addition, these two indirect effects were statistically significant only when perfectionistic concerns were medium and high. The results support the proposed conditional model and suggest the interplay between dimensions of perfectionism is important for athletes' post-competition mood, and the level of perfectionistic concerns, especially.

Behavioral genetics of temporal framing: Heritability of time perspective and its common genetic bases with major personality traits.

OBJECTIVE: The present study aimed to provide a seminal behavioral genetic analysis of time perspectives (TPs). Moreover, we intended to investigate the magnitude of genetic vs. environmental components of the well-established assocations between TPs and personality features. BACKGROUND: Individual differences in temporal framing processes, referred to as TPs, are vital psychological and behavioral outcomes. Although proponents of TP theory emphasize mainly environmental origins of the tendencies to adopt certain TPs, research provides evidence for marked associations between the temporal dimensions and major personality traits that are known to be heritable. Hence, it was essential to empirically verify these claims. METHOD: The article reports an analysis of genetic and environmental components of variance in TPs based on a study adopting a twin design, conducted on a sample of 393 pairs of twins (135 monozygotic and 258 dizygotic). RESULTS: Multivariate Cholesky decomposition supported an EA model assuming impacts of both unshared environmental factors (E) and additive genetic factors (A) across all TP dimensions, suggesting that the effects of shared environment on TPs are plausibly negligible. Heritability indices of TPs ranged between 0.51 for Present-Fatalistic and 0.62 for Present-Hedonistic, suggesting that the majority of the variance in TPs stems from genetic influences. Substantial genetic correlations were found between TPs and the Big Five personality traits. CONCLUSIONS: The findings provide further evidence for conceptualizing TPs as biologically based personality traits and challenge the claims that TP is mainly a product of culture, education, and personal experiences.

Godless owls, devout larks: Religiosity and conscientiousness are associated with morning preference and (partly) explain its effects on life satisfaction.

The associations between morningness-eveningness, conscientiousness, and religiosity have not been investigated to date. The aim of the present research was to provide evidence for the relationships between these dimensions. Moreover, we tested whether the well-established link between morningness and life satisfaction could be explained by elevated religiosity of morning-oriented individuals and whether this relationship may be mediated by conscientiousness. The investigation was conducted on two independent samples of Polish adults (N = 500 and N = 728). Our results corroborated earlier findings that morningness was positively associated with both conscientiousness and satisfaction with life. We also found evidence for a significant positive association between morningness and religiosity. Moreover, controlling for age and gender, we obtained significant mediation effects showing that the association between morningness-eveningness and satisfaction with life might stem, at least in part, from the higher religiosity among morning-oriented individuals, also when conscientiousness was included in the model. It means that more morning-oriented individuals may benefit from higher psychological well-being thanks to both personality characteristics and attitudes towards religion.

Time perspective affects daily time use and daily functioning in individuals with Schizophrenia Spectrum Disorders: Results from the multicentric DiAPAson study.

Time perspective (TP) influences various aspects of human life. We aimed to explore the associations between TP, daily time use, and levels of functioning among 620 patients (313 residential patients and 307 outpatients) with a diagnosis of Schizophrenia Spectrum Disorders (SSD) recruited from 37 different centres in Italy. The Brief Psychiatric Rating Scale and the Specific Levels of Functioning (SLOF) were used to assess psychiatric symptoms severity and levels of functioning. Daily time use was assessed using an ad hoc paper and pencil Time Use Survey. The Zimbardo Time Perspective Inventory (ZTPI) was used to assess TP. Deviation from Balanced Time Perspective (DBTP-r) was used as an indicator of temporal imbalance. Results showed that the amount of time spent on non-productive activities (NPA) was positively predicted by DBTP-r (Exp(ß): 1.36; p .003), and negatively predicted by the Past-Positive (Exp(ß): 0.80; p .022), Present-Hedonistic (Exp(ß): 0.77; p .008), and Future (Exp(ß): 0.78; p .012) subscales. DBTP-r significantly negatively predicted SLOF outcomes (p .002), and daily time use, in particular the amount of time spent in NPA and Productive Activities (PA), mediated their association. Results suggested that rehabilitative programs for individuals with SSD should consider fostering a balanced time perspective to reduce inactivity, increase physical activity, and promote healthy daily functioning and autonomy.

The moderating role of dispositional mindfulness in the associations of morningness-eveningness with depressive and anxiety symptoms.

Several studies have shown that eveningness is positively related to both depressive and anxiety symptoms. However, little is known about factors that may play a protective role against the undesirable emotional consequences of evening preference. Thus, in the present study, we explored the moderating effects of dispositional mindfulness on the relationship between morningness-eveningness and the presence of depressive symptoms, as well as between morningness-eveningness and the presence of anxiety symptoms. The study was conducted on a group of 1107 individuals (559 women and 548 men) aged 18-55 years (M = 36.26, SD = 9.89). Consistent with previous findings, eveningness was positively related to the presence of both depressive and anxiety symptoms. The magnitude of these effects decreased with higher dispositional mindfulness. The latter result remained significant when the analogical moderating effects of personality, established in earlier studies, were controlled for in the regression models. This leads to the conclusion that dispositional mindfulness may act as a protective factor against the elevated depressive and anxiety symptoms reported by evening-oriented individuals.

God save the owls! Religiosity moderates the relationship between morningness-eveningness and depressive symptoms.

Studies show that eveningness preference and depressive symptoms are positively related. However, little is known about possible factors that could reduce this association. In the present study, we examine the moderating effects of religiosity on the relationship between eveningness and depressive symptoms. The main analyses were conducted on a group of 606 individuals (300 women and 306 men) aged 18 to 36 years (M = 29.00, SD = 4.95). The participants completed the Composite Scale of Morningness, the Patient Health Questionnaire-9, and the Centrality of Religiosity Scale. Our results confirmed earlier findings that eveningness was positively related to depressive symptoms. The magnitude of this association decreased with higher religiosity. This lead to the conclusion that religiosity may act as a protective factor against elevated depressive symptoms among evening-oriented individuals.

Leaving Past Adversities Behind: Gratitude Intervention Compensates for the Undesirable Effects of Past Time Perspectives on Negative Affect.

Both gratitude and savoring the moment are considered to be well-established "well-being boosters" (WBBs). Each of them has a salient temporal reference: Gratitude is past-related, whereas savoring the moment refers to the present. The temporal match-mismatch model posits that time perspectives (TPs) moderate the effects of WBBs on well-being if they refer to the same temporal frame (e.g., gratitude and Past-Positive). Our study tested whether TPs moderate the effects of two positive interventions on positive affect (PA) and negative affect (NA). The participants (N = 174 individuals, 73% women) completed measures of TPs, PA, and NA, followed by a brief intervention of gratitude (N = 86) or savoring (N = 88). Subsequently, they completed the PA/NA measures again. Both interventions significantly decreased NA but did not foster PA. The magnitude of the shift in NA in the gratitude condition depended on the levels of past TPs: Individuals high in Past-Negative and low in Past-Positive displayed greater baseline NA than their counterparts; however, the difference was leveled after the gratitude intervention. No interaction effects between the present TPs and the savoring intervention were observed. The results suggest that practicing gratitude may diminish the undesirable consequences of negative views of the past.

Analyzing social perception of chronotypes within the stereotype content model.

In the present article, we attempted to analyze the social perceptions of morning and evening chronotypes using the framework of the stereotype content model which posits that all social impressions and group stereotypes form along two basic dimensions: warmth and competence. The participants (N = 1277; 53% women) completed the Composite Scale of Morningness (CSM) and a questionnaire measuring beliefs about social perceptions of Morning-types and Evening-types. Bottom 10%, middle 20% and top 10% of the CSM distribution (N = 501 individuals) were selected as representatives of 'pure' chronotypes: evening ('E-types'), intermediate ('N-types') and morning ('M-types'). In the entire sample, M-types were perceived as markedly more competent and marginally warmer than E-types. When we took into account the perceivers' own chronotypes, only the perceptions reported by N-types were consistent with that pattern. M-type perceivers displayed analogic albeit markedly stronger positive views of their ingroups, whereas E-types believed that individuals sharing their diurnal preference are equally competent but more warm compared to M-types. It seems that social perceptions of chronotypes emerge as a composition of two effects: the socially shared stereotype (emphasizing high competence of M-types) and ingroup-serving biases, resulting in viewing people sharing the perceiver's own chronotype in a more favorable way.

I love the way you love me: Responding to partner's love language preferences boosts satisfaction in romantic heterosexual couples.

Chapman's Love Languages hypothesis claims that (1) people vary in the ways they prefer to receive and express affection and (2) romantic partners who communicate their feelings congruent with their partner's preferences experience greater relationship quality. The author proposes five distinct preferences and tendencies for expressing love, including: Acts of Service, Physical Touch, Words of Affirmation, Quality Time and Gifts. In the present study partners (N = 100 heterosexual couples) completed measures assessing their preferences and behavioral tendencies for a) expressions of love and b) reception of signs of affection, for each of the five proposed "love languages". Relationship satisfaction, sexual satisfaction and empathy were also assessed. The degree of the within-couple mismatch was calculated separately for each individual based on the discrepancies between the person's felt (preferred) and their partner's expressed love language. The joint mismatch indicator was a sum of discrepancies across the five love languages. Matching on love languages was associated with both relationship and sexual satisfaction. In particular, people who expressed their affection in the way their partners preferred to receive it, experienced greater satisfaction with their relationships and were more sexually satisfied compared to those who met their partner's needs to lesser extent. Empathy was expected to be a critical factor for better understanding of and responding to the partner's needs. Results provided some support for this hypothesis among male but not female participants.

Social support mediates the effect of morningness on changes in subjective well-being over 6 months.

Studies show that morningness is positively associated with subjective well-being. Our previous research investigated factors that could underlie this relationship, finding that the association between morningness-eveningness and subjective well-being can be partially attributed to the higher levels of perceived social support received by morning-oriented individuals. In the present study, we examine the longitudinal effects of perceived social support in mediating the relationship between morningness-eveningness and subjective well-being. Our results show that this mediating effect remains significant with respect to changes in well-being over a 6-month period. It seems that the causal effect of morningness on well-being may be partially mediated by the causal effect of social support. The findings provide further support for the conclusion that perceived social support is an important contributing factor to the greater well-being reported by morning-oriented individuals. Additionally, our results provide seminal evidence for the causal effect of morningness on well-being.

The moderating role of personality traits in the associations between seasonal fluctuations in chronotype and depressive symptoms.

Recent research provided evidence that the well-established association between morningness-eveningness and depressive symptoms may be moderated by personality features - conscientiousness and neuroticism. In the present study, we attempted to broaden these findings using a longitudinal design. We hypothesized that these personality traits may influence the degree to which morningness-eveningness and depressiveness covary in time. Participants (n = 380) filled measures of morningness-eveningness, the Big Five personality, and depressive symptoms twice, in December and in June. Consistent with previous results, we observed a significant seasonal shift towards morningness and lower depressive symptoms from December to June. Seasonal shifts in chronotype and depressive symptoms were interrelated: a seasonal shift towards morningness was associated with a decrease in depressive symptoms. The strength of this association was exaggerated by neuroticism but attenuated by conscientiousness, suggesting that among neurotic individuals seasonal changes in depressive symptomatology are more dependent on seasonal shifts in morningness-eveningness but less dependent among conscientious ones. This result suggests that conscientiousness and emotional stability play a protective role against maladaptive consequences of eveningness.

Seeking Causality in the Links between Time Perspectives and Gratitude, Savoring the Moment and Prioritizing Positivity: Initial Empirical Test of Three Conceptual Models.

We provide an initial empirical test of three conceptual models reflecting possible patterns of causality effects in the relationships between time perspective (TP), gratitude, savoring the moment, and prioritizing positivity (referred to as well-being boosters, WBBs), and mental well-being. The first one, trait-behavior model, states trait TPs increase the tendency to use specific WBBs in order to increase mental well-being. The second model, the accumulation model, proposes that a regular practice of particular WBBs fosters adaptive TPs which in turn impact well-being. The third model, the feedback loop, suggests that WBBs and positive TPs reciprocally strengthen one another and together contribute to higher mental well-being. Participants (N = 206; Mage = 30.90, SD = 8.39, 74% females) filled questionnaires measuring TPs, WBBs, and well-being twice, in a one-year interval. Using cross-lagged panel analyses we examined the direction of causation in the relationships among the variables. Past-Positive had a significant cross-lagged effect on gratitude, Present-Fatalistic had a significant effect on savoring. Both Past-Negative and Present-Fatalistic perspectives displayed significant causal effects on well-being. The results partly support the trait-behavior model. However, given that the second wave was conducted shortly after the onset of the COVID-19 pandemic, further studies are required to better understand the interplay between the studied traits.

Perfectionism Moderates the Effects of Goal-Realization on Post-Competition Mood in Amateur Runners.

Perfectionism impacts how athletes evaluate their performance. However, little is known about how perfectionistic strivings and perfectionistic concerns interplay with athletes' anticipated and actual performance in predicting mood after the competition. Thus, we conducted a study with amateur runners [n = 152, (72 female, 80 male); Mean±SD age = 34.71 ± 9.57] taking part in a competitive 10-kilometer street run. Perfectionism was measured before the run, while the measurement of mood was taken during the post-competition week. Mood was operationalized in the 3D model of mood, distinguishing between energetic arousal, tense arousal, and hedonic tone. Regression analysis showed that specific patterns of associations between perfectionism and goal-realization explain 17-21% of variance in the dimensions of mood. Higher pleasure after the run was predicted by lower perfectionistic concerns and better conversion of anticipated performance into actual performance. In predicting energy and tension, moderating effects of perfectionistic strivings, perfectionistic concerns, and conversion rate were observed. Johnson-Neyman technique revealed that only athletes low in perfectionistic concerns were able to benefit from lower tension when they met or exceeded their goals for the run. The higher athletes' perfectionistic strivings and conversion rate the more pronounced effects we observed for affect-energization. Results support the idea of perfectionistic reactivity, where the negative consequences of perfectionism can be observed in a lack of positive reactions to positive events. We also suggest that such a response to meeting or exceeding one's goal may contribute to the development of athlete burnout and hinder the development athlete engagement.

The moderating role of personality traits in the relationship between chronotype and depressive symptoms.

Due to the undeniably morning orientation of the social clock, the evening chronotype can be associated with negative consequences, both at the affective and cognitive levels. Evening-oriented individuals are more susceptible to affective disorders, show poorer educational achievements and consume stimulants more often than morning-oriented individuals. However, little is known about potential factors that may attenuate or amplify these negative emotional consequences of the evening preference. Thus, our aim was to examine whether personality traits interplay with chronotype in predicting depressive symptoms. We assessed the Big Five and the Big Two personality traits, morningness-eveningness and depressive symptoms in an online sample of 913 Polish individuals (468 females, 445 males), aged 18-35 (M = 26.34, SD = 5.15). Eveningness, higher neuroticism, lower conscientiousness and lower alpha-stability were associated with higher depressive symptoms. The magnitude of the association between eveningness and depressive symptoms decreased with higher conscientiousness and alpha-stability, as well as with lower neuroticism. In conclusion, high neuroticism, low conscientiousness and low alpha-stability increase the risk of depressive symptoms, particularly among evening chronotypes. The patients' chronotypes and personality traits should be taken into account in both the prevention and diagnostics of depression.

The mediating role of perceived social support in the relationship between morningness-eveningness and subjective well-being.

Studies show that morningness preference and subjective well-being are positively related. However, little is known about potential factors that may underpin this association. In the present study, we explored the mediational role of general social support and its facets (family, friends, and significant other) in the relationship between morningness-eveningness and subjective well-being. The present study was conducted with a sample of 1,067 adults (51% women), with a mean (SD, range) age of 36.41 (9.95, 18-55) years. Our results corroborated earlier findings that morningness was positively associated with both subjective well-being and social support. Controlling for age and gender, we obtained significant mediation effects, showing that the association between morningness-eveningness and subjective well-being might stem, at least in part, from the higher levels of social support received by morning-oriented individuals. This may lead to the conclusion that social support is an important antecedent of the greater well-being reported by morning-oriented individuals.

Moral foundations in chronotypes: morningness predicts conservative morality.

Recent studies suggest that chronopsychological variables may play an important role in moral behavior. In the present study, we aimed to test whether a person's chronotype is associated with moral foundations profiles, distinguished in accordance with Haidt's conceptualization. Morning-oriented people generally tended to rank the importance of the five basic moral foundations - Harm/Care, Fairness/Reciprocity, Ingroup/Loyalty, Authority/Respect, and Purity/Sanctity, highest. Moreover, morningness predicted the affiliation to the "conservative" cluster, as opposed to the "liberal" moral foundations profile. However, after conscientiousness was added to the model, the effect of chronotype was no longer significant. Thus, it seems that the more conservative morality of morning people stems mainly from their elevated conscientiousness. In addition to broadening the current knowledge about the morningness-eveningness' nomological network, the present results may have some practical implications, e.g., for political marketing strategies.
