The present experience sampling study investigated the effect of age on emotion regulation patterns (i.e., emotion regulation strategy effectiveness, variability, and differentiation) in daily life. The study further explored the implications of potential age differences in emotion regulation patterns for well-being. A sample of 406 adults (age range: 18–81, 62.8% female) were prompted five times a day for seven days to rate momentary emotions, emotion regulation strategy use, and emotion regulation strategy effectiveness. Based on these ratings, indicators of emotion regulation variability and differentiation were calculated. Well-being outcomes included daily positive and negative emotions, and symptoms of depression and anxiety assessed at baseline. The findings revealed reduced emotion regulation variability with age and a negative association between emotion regulation variability and well-being. There were no associations between age and emotion regulation effectiveness or differentiation. Emotion regulation effectiveness was associated with more positive and less negative daily emotions, and these associations were stronger for younger adults compared to older adults. Drawing on prominent lifespan theories, the findings may indicate that as people age, they select and apply a few strategies that they know will be effective given the context and their resources which leads to reduced emotion regulation variability but ultimately more well-being. Concerning emotion regulation effectiveness, the findings suggest that effectiveness is less important for emotional well-being in daily life in older adulthood possibly because well-being is determined by other factors (e.g., less frequent and more predictable stressors) with age.  相似文献

Much anecdotal evidence suggests that sleep deprivation not only impairs performance, but also brings about other extraordinary effects like hallucinations. However, knowledge about how sleep deprivation may trigger hallucinations is limited. To qualitatively describe hallucinatory experiences during sleep deprivation 12 male military officers from the Norwegian Armed Forces who all had experienced at least one sleep loss-induced hallucinatory experience were recruited. Data were collected and analyzed by semi-structured interviews and thematic analysis. This resulted in the identification of three distinct main themes: (1) Modalities, (2) circumstances/triggers and (3) reactions to hallucinations. Hallucinations were experienced in several modalities (visual, auditory and multi-modality), although visual hallucinations seemed to dominate. Typical reported circumstances/triggers were sleep loss, physical exhaustion, time-of-day, low calorie intake, mental exhaustion and lack of external stimuli (low sensory and social input, boring situations, and monotonous activity). Negative emotions were dominant during the hallucinatory episodes. Often some reasoning and checking on behalf of the officers were necessary to differentiate between real percepts and hallucinations. In some cases the hallucinations caused erroneous actions. Retrospectively, most officers viewed their hallucinatory experiences in light of positive emotions and several emphasized having learned something from them. The results are discussed in relation to the existing literature and suggestions for future studies are outlined.  相似文献

Social and emotional loneliness negatively impact several areas of health, including sleep. However, few comprehensive population‐based studies have evaluated this relationship. Over 12,000 students aged 21–35 years who participated in the student survey for higher education in Norway (the SHoT study) were assessed. Loneliness was assessed using the Social and Emotional Loneliness Scale. Difficulty initiating and maintaining sleep (DIMS) was assessed by a single‐item subjective response on the depression scale of the Hopkins Symptoms Checklist (HSCL‐25). Social loneliness was associated with more serious DIMS (unadjusted proportional odds‐ratio [OR] = 2.69, 95% CI = 2.46–2.95). This association was attenuated following adjustment for anxiety (adjusted OR = 1.92, 95% CI = 1.75–2.10) and depression (adjusted OR = 1.48, 95% CI = 1.34–1.63), however was not substantially altered when all demographics and psychological distress were accounted for (fully adjusted OR = 1.46, 95% CI = 1.30–1.63). Emotional loneliness was also associated with more serious DIMS (unadjusted proportional OR = 2.33, 95% CI = 2.12–2.57). Adjustment for anxiety (adjusted OR = 1.96, 95% CI = 1.78–2.15) and depression (adjusted OR = 1.64, 95% CI = 1.48–1.80) attenuated, but did not extinguish this relationship in the fully adjusted model (adjusted OR = 1.22, 95% CI = 1.09–1.31). Mediation analyses revealed that the social loneliness‐DIMS association was fully attributed to psychological distress, while the emotional loneliness‐DIMS association was only partially mediated, and a direct association was still observed. Associations between social and emotional loneliness and subjective DIMS were embedded in a larger pattern of psychological distress. Mitigating underlying feelings of loneliness may reduce potentially deleterious effects on sleep health and psychological wellbeing in young adults.  相似文献

Since 1998, soldiers deployed to war zones with the Danish Defense (≈31,000) have been invited to fill out a questionnaire on post‐mission reactions. This provides a unique data source for studying the psychological toll of war. Here, we validate a measure of PTSD‐symptoms from the questionnaire. Soldiers from two cohorts deployed to Afghanistan with the International Security Assistance Force (ISAF) in 2009 (ISAF7, N = 334) and 2013 (ISAF15, N = 278) filled out a standard questionnaire (Psychological Reactions following International Missions, PRIM) concerning a range of post‐deployment reactions including symptoms of PTSD (PRIM‐PTSD). They also filled out a validated measure of PTSD‐symptoms in DSM‐IV, the PTSD‐checklist (PCL). We tested reliability of PRIM‐PTSD by estimating Cronbach's alpha, and tested validity by correlating items, clusters, and overall scale with corresponding items in the PCL. Furthermore, we conducted two confirmatory factor analytic models to test the factor structure of PRIM‐PTSD, and tested measurement invariance of the selected model. Finally, we established a screening and a clinical cutoff score by application of ROC analysis. We found high internal consistency of the PRIM‐PTSD (Cronbach's alpha = 0.88; both cohorts), strong item‐item (0.48–0.83), item‐cluster (0.43–0.72), cluster‐cluster (0.71–0.82) and full‐scale (0.86–0.88) correlations between PRIM‐PTSD and PCL. The factor analyses showed adequate fit of a one‐factor model, which was also found to display strong measurement invariance across cohorts. ROC curve analysis established cutoff scores for screening (sensitivity = 1, specificity = 0.93) and clinical use (sensitivity = 0.71, specificity = 0.98). In conclusion, we find that PRIM‐PTSD is a valid measure for assessing PTSD‐symptoms in Danish soldiers following deployment.  相似文献

The aim of the present randomized double‐blind placebo control trial was to investigate if vitamin D supplementation had an effect on vitamin D status, executive functioning and self‐perceived mental health in a group of Norwegian adolescents during winter time. Fifty adolescents were randomly assigned into an intervention group (vitamin D pearls) or a control group (placebo pearls). Before (pre‐test in December/January) and after (post‐test in April/May) the intervention period the participants were exposed to a test procedure, consisting of blood draw, completion of cognitive tests (Tower of Hanoi and Tower of London), and the Youth Self‐report version of the Child Behavior Checklist. Multivariate data analysis showed that participants with low vitamin D status scored worse on the Tower of London tests and the more difficult sub‐tasks on the Tower of Hanoi tests. They also had a tendency to report higher frequency of externalizing behavior problems and attention deficit. At pre‐test, the overall mean vitamin D status measured as 25‐hydroxy vitamin D was 42 nmol/L, defining deficiency (Intervention group = 44 nmol/L, Control group = 39 nmol/L). However, vitamin D supplementation caused a significant increase in vitamin D status resulting in a sufficient level in the Intervention group at post‐test (mean 62 nmol/L). The results also revealed that the intervention group improved their performance on the most demanding sub‐tasks on the ToH. Overall, the study indicates that vitamin D status in adolescents may be important for both executive functioning and mental health.  相似文献

Although auditory distractions are prevalent and often seen as a threat to performance, relatively few studies have explored distraction effects in an applied sport context. This field experiment examined expert golfers' (n = 36) competitive performance in a normal and a distracting condition. The results displayed similar performance in the two conditions. Participants' responses to a postcompetition questionnaire generally suggested that they found auditory distractions below moderately disturbing and detrimental to their performance. Overall, our results contradict the popular consensus that distractions are disturbing and detrimental in motor performance contexts.  相似文献

War experiences are known risk factors for post-traumatic stress disorder (PTSD) and other poor psychosocial outcomes. This study aimed to assess the extent to which perpetrating violence (operationalised as intentional and unintentional killing or mutilation) and being a victim of violence (operationalised as being a victim of violence, e. g., witnessing violence, injuries, torture) predict PTSD and other psychosocial outcomes independently in war-affected youth of Northern Uganda. Data on war experiences, PTSD, psychosocial problems, and socio-demographic characteristics were collected from the youth formerly abducted by the Ugandan Lord’s Resistance Army (LRA) at baseline (mean age = 22.39 years; SD = 10.47) and at follow-up (mean age = 23.52 years; SD = 9.28) using self-report questionnaires. On average, the participants spent 3.13 years in captivity (SD = 2.99) and were abducted at 14.14 years of age (SD = 4.21). Regression models were fitted to predict PTSD and psychosocial outcomes from perpetrating violence controlling for being a victim of violence and demographic characteristics. Thirty-seven percent (n = 168) reported killing or being responsible for killing while in rebel captivity. After adjusting for being a victim of violence, perpetrating violence remained a statistically significant predictor of PTSD and poor psychosocial outcomes such as depression, anxiety, somatic complaints, psychotic symptoms, and conduct problems. Among war-affected youth returning from LRA captivity, perpetrating violence may just be as toxic a risk factor for PTSD and other psychosocial outcomes as being a victim of violence. Mental health workers should consider both the effects of being a victim of violence and perpetrating violence in treatment planning.  相似文献

Abnormalities in emotion recognition (ER) are frequently reported in depression, with lower recognition accuracy in patients with major depressive disorder (MDD) when compared to healthy individuals. Mindfulness was found to directly impact the severity of depressive symptoms, by recognizing negative cognitions and dysfunctional reactions. The aims of this study were to compare ER and mindfulness levels between MDD patients and healthy controls (HCs), as well as to examine whether ER and mindfulness are related to symptom severity in MDD patients. Sixty-eight patients with MDD and 93 HCs participated in the study. A sociodemographic form, reading the mind in the eyes test (RMET), five facet mindfulness questionnaire-short form (FFMQ-S) and the Montgomery–Asberg depression scale (MADRS) were administered. Group comparison in ER and mindfulness was performed using the multivariate analysis of covariance (MANCOVA). Bivariate correlations and hierarchical linear regression analyses were performed to assess the associations between depression severity, ER and mindfulness in the patient group. Higher level of mindfulness was found in HCs relative to MDD group, however, no ER difference was present between the groups. A positive association between depression severity and the non-reactivity facet of mindfulness was found. On the other hand, ER was not significantly associated with symptom severity among individuals with MDD. Non-reactivity, unlike other dimensions of mindfulness, seems to increase with the severity of depressive symptoms among MDD patients. A particular focus on this subdimension in mindfulness techniques may yield better outcomes in alleviation of depressive symptoms.  相似文献
