恐惧的代价：疼痛恐惧、心理忧虑和躯体化对疼痛感知预测作用的比较

首次在无痛群体中比较疼痛恐惧、心理忧虑和躯体化对疼痛感知的预测作用大小及调节和中介关系。以多个同类量表得分的Z分数加和作为三者的因子分,以冷压痛觉测验（CPT）疼痛指标（阈限、耐受性、强度、不愉快度）为目标变量,通过分层回归及调节和中介作用分析,发现疼痛恐惧对疼痛不愉快度的预测作用最强,心理忧虑对疼痛体验（强度、不愉快度）的预测作用被疼痛恐惧完全中介,躯体化只有在高疼痛恐惧条件下才显著负向预测疼痛不愉快度。综上,疼痛恐惧是三因素中预测CPT疼痛体验的主要因素。     

Social and emotional loneliness and self‐reported difficulty initiating and maintaining sleep (DIMS) in a sample of Norwegian university students

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.     

Sleep deprivation and stressors: Evidence for elevated negative affect in response to mild stressors when sleep deprived

Stress often co-occurs with inadequate sleep duration, and both are believed to impact mood and emotion. It is not yet known whether inadequate sleep simply increases the intensity of subsequent stress responses or interacts with stressors in more complicated ways. To address this issue, we investigated the effects of one night of total sleep deprivation on subjective stress and mood in response to low-stress and high-stress cognitive testing conditions in healthy adult volunteers in two separate experiments (total N = 53). Sleep was manipulated in a controlled, laboratory setting and stressor intensity was manipulated by changing difficulty of cognitive tasks, time pressure, and feedback about performance. Sleep-deprived participants reported greater subjective stress, anxiety, and anger than rested controls following exposure to the low-stressor condition, but not in response to the high-stressor condition, which elevated negative mood and stress about equally for both sleep conditions. These results suggest that sleep deprivation lowers the psychological threshold for the perception of stress from cognitive demands but does not selectively increase the magnitude of negative affect in response to high-stress performance demands.

Sense of coherence as a protective factor for psychological distress among gay men: a prospective cohort study

Gay men face a greater risk of psychological distress than heterosexual men, yet research on protective factors among gay men has been limited. This prospective cohort study investigated whether a sense of coherence (SOC), as a form of coping, helps to protect against psychological distress among middle-aged and older gay men. A nationwide online survey was conducted among a baseline sample of 1135 Australian gay-identified men aged 40 years and older, with a follow-up survey 12 months later. SOC was measured using the 13-item SOC Scale. Psychological distress was measured using the K10 Psychological Distress Scale. Hierarchical regressions were conducted, with analyses controlling for several potential risk factors for distress. Over half of participants had moderate or high psychological distress. However, baseline distress was significantly lower among those with stronger baseline SOC. In addition, baseline SOC significantly predicted distress 12 months later. This predictive effect of SOC was independent of baseline distress levels and occurred despite a strong correlation between baseline and follow-up distress. With SOC appearing to be a protective factor, strategies among middle-aged and older gay men that strengthen SOC may assist in the prevention and treatment of anxiety and other psychological distress in this vulnerable population.     

Mindfulness May Buffer Psychological Distress in Adolescents during the COVID-19 Pandemic: The Differential Role of Mindfulness Facets

The COVID-19 pandemic strongly impacts adolescents’ mental health, a population particularly vulnerable to mental disorders, highlighting the need to identify protective factors against COVID-19 related psychological distress to inform policies and intervention strategies. Previous research suggests that mindfulness may be a promising factor that can lower the risk of detrimental psychological consequences related to the COVID-19 pandemic. However, it is currently unknown which aspects of mindfulness contribute most to its protective effects. Moreover, previous studies mainly focused on adult samples. The present study aimed to address this gap by investigating the impact of specific mindfulness facets on adolescents’ COVID-19 related psychological functioning. 246 Dutch-speaking adolescents were recruited via social media to complete a cross-sectional online survey between June 29 and October 11, 2020. Participants were 16–18 years of age, most of them women (71%), and the majority followed the highest level of Belgian secondary education. Logistic regression analyses were performed to test the differential effects of each mindfulness facet on psychological functioning. Our results identified decentering as the facet of mindfulness that was uniquely associated with decreased worry and stress, improved mental health and quality of life, as well as with an increase in social connectedness with others following the outbreak of the COVID-19 pandemic. Unexpectedly, decentering was negatively associated with adolescents’ helping behaviour during compared to before the pandemic. Implications for research on and application of mindfulness are discussed. Taken together, these findings suggest that the facet of decentering, among all facets of mindfulness, may represent the main protective factor against psychological distress during the COVID-19 pandemic.     

Sleep,resilience, and psychological distress in United States military Veterans

Sleep problems are prevalent among Veterans. Left untreated, such problems may elevate psychological distress and increase risk of subsequent mental health disorders. Psychological resilience may buffer against negative psychological outcomes, yet the relationship between sleep and resilience has not been studied. This study explored poor sleep, resilience, and psychological distress using questionnaires collected as part of the Study of Post-Deployment Mental Health. Participants (N = 1,118) had served in the US military since September 11, 2001, had one or more overseas deployments, and were free from a past-month DSM-defined mental health disorder. Hierarchical linear regression was used to examine the association between poor sleep quality (Pittsburgh Sleep Quality Index total score) and psychological distress (Global Symptom Index; Symptom Checklist-90-R), controlling for demographic and health characteristics. Moderation analyses tested for a potential buffering effect of resilience (Connor-Davidson Resilience Scale). Poor sleeping Veterans had worse physical and psychological health, lower resilience, and endorsed more lifetime traumatic events. Poor sleep was associated with greater psychological distress controlling for health and demographic characteristics. Both resilience factors—adaptability and self-efficacy—had significant buffering effects on the relationship between poor sleep and psychological distress, suggesting that resilience may protect against negative outcomes in poor sleepers. Additional research is warranted to better understand the relationships between sleep, resilience, and psychological distress. Such research may inform pertinent prevention efforts, including interventions that improve sleep, enhance resilience, and protect against incident mental health diagnoses.     

Changes in sleep quality and levels of psychological distress during the adaptation to university: The role of childhood adversity

Stress-related sleep disturbances are common, and poor sleep quality can negatively affect health. Previous work indicates that early-life adversity is associated with compromised sleep quality later in life, but it is unknown whether it predicts greater declines in sleep quality during stressful life transitions. We propose and test a conceptual model whereby individuals who reported experiencing greater levels of child maltreatment would experience greater psychological distress during a stressful life transition, which in turn would contribute to greater declines in sleep quality, relative to their quality of sleep before the stressful transition. Controlling for potential confounding variables (e.g., age, gender), structural equation modelling demonstrated that psychological distress experienced during a stressful transition (i.e., beginning life at university) mediated the relationship between childhood emotional neglect and changes in sleep quality. The hypothesized model demonstrated a good overall fit to the data, χ ² (15) = 17.69, p = .279, CFI = .99, TLI = .97, SRMR = .04, RMSEA = .04 (90% CI <0.001–0.09). Emotional neglect (β = .22) was positively associated with psychological distress which in turn was positively associated with poor sleep quality (β = .31) during a stressful transition. Future research should aim to understand the specific stressors in the university environment that are most challenging to individuals who faced early-life emotional maltreatment. These findings will help inform interventions to facilitate adaptation to a new environment and improve sleep quality for these university students.     

Cognitive Behavioral Treatment for Insomnia in Veterans with Long-Standing Posttraumatic Stress Disorder: A Pilot Study

This uncontrolled pilot study assessed the effects of cognitive behavioral therapy for insomnia in veterans with long-standing posttraumatic stress disorder. Male veterans with current chronic insomnia and PTSD (n?=?8; M age = 58.6, SD?=?3.0; 87.5% African American, 12.5% European American; 87.5% Vietnam Veterans, 12.5% 1st Gulf War Veterans) reported a trauma related to their military service. Participants appeared for five weekly individual sessions of cognitive behavioral therapy for insomnia and completed one-week assessments of objective sleep (actigraphy) and subjective sleep (sleep diaries), the Insomnia Severity Index, and measures of functioning, posttraumatic stress disorder, and psychological distress both before and after treatment. Paired t tests revealed significant posttreatment improvements for various subjective assessments of sleep patterns but actigraphy-defined sleep was unchanged. Measures of functioning, nightmares, and posttraumatic stress disorder severity were also unchanged at posttreatment. Preliminary results were encouraging in improving subjective perceptions of sleep in individuals with posttraumatic stress disorder, warranting further study with more rigorous methodology.     

Daily hassles,marital functioning and psychological distress among community-dwelling older couples

ObjectivesThis study attempts to examine the association between stress induced by daily hassles, marital functioning and psychological distress among a sample of older couples living at home without assisted living facilities. Moreover, the study looks to assess the moderator role of marital functioning on the association between stress and psychological distress.MethodsThe study included a representative sample of 508 older couples living at home where at least one spouse was aged 65 years or older. To take into account of the non-independence of the data, dyadic analyses were conducted.ResultsFor men, marital functioning and stress induced by daily hassles explained the variance of psychological distress 4.71% and 2.56% respectively. For women, these variables explained 10.96% and 2.43% respectively of this variance. Results found also that marital functioning can play a protective role between the association of stress and psychological distress among men, but not for women. Men with lower marital functioning present a significant higher level of psychological distress when they present stress than those who do not have stress. For those with high marital functioning, no significant differences have been found on psychological distress between those groups.ConclusionStress induced by daily hassles and marital functioning are significantly related to psychological distress among older people, and, for men, marital functioning can play a protective role in the association between those variables.     

Relationship of Mindfulness to Distress and Cortisol Response in Adolescent Girls At-Risk for Type 2 Diabetes

Altered stress response theoretically contributes to the etiology of cardiometabolic disease. Mindfulness may be a protective buffer against the effects of stress on health outcomes by altering how individuals evaluate and respond to stress. We engaged adolescent girls at risk for developing Type 2 diabetes in a cold-pressor test in order to determine the relationship of dispositional mindfulness to cortisol response and subjective stress, including perceived pain and unpleasantness during the stressor, and negative affect following the stressor. We also evaluated mindfulness as a moderator of psychological distress (depressive/anxiety symptoms) and stress response. Participants were 119 girls age 12–17 years with overweight/obesity, family history of diabetes, and mild-to-moderate depressive symptoms. Greater mindfulness was associated with less perceived pain and negative affect, but was unrelated to cortisol response to the stressor. Regardless of mindfulness, greater depressive/anxiety symptoms related to a more blunted cortisol response. Mindfulness might promote better distress tolerance in adolescents at risk for diabetes by altering how youth perceive and relate to acute stress, rather than through altering the physiological stress response. At all levels of mindfulness, depressive/anxiety symptoms relate to greater blunting of cortisol response. Findings contribute to emerging literature on the role of mindfulness in promoting the mental and physical health and well-being of individuals at risk for Type 2 diabetes.     

Patterns of psychological distress in mothers of preterm infants

Mothers of preterm infants experience significant psychological distress, with elevated levels of inter-correlated depressive, stress, anxiety and post-traumatic stress symptoms. In a sample of racially and ethnically diverse mothers of preterm infants, we identified differing patterns of psychological distress during infant hospitalization and examined the effect of these psychological distress patterns on longitudinal trajectories of each psychological distress measure and on maternal perceptions of the child over the first year of the infant's life. Mothers of preterm infants (N = 232) completed five questionnaires assessing depressive symptoms, anxiety, post-traumatic stress symptoms, stress due to infant appearance, and stress due to parental role alteration during enrollment during the neonatal hospitalization, discharge, and at 2, 6, and 12 months of age adjusted for prematurity. Latent class analysis on the enrollment psychological distress variables allowed us to identify five sub-groups of mothers exhibiting similar patterns of psychological distress, differing primarily in degree and type: low distress, moderate distress, high NICU-related distress, high depressive and anxiety symptoms, and extreme distress. These classes continued to show different longitudinal trajectories for the psychological distress measures through 12 months corrected age. Mothers in the extreme distress class and, to a lesser degree, mothers in the high depressive and anxiety symptom class remained at risk of significant psychological distress one year after discharge and had less positive perceptions of their child (greater worry and higher perceptions of child vulnerability). In conclusion, distinctive sub-groups of mothers during hospitalization had different patterns of psychological distress throughout the 12-month period and may require different interventions in the NICU.     

L’évolution des facteurs prédictifs de la détresse psychologique des étudiants en contexte de Covid-19 : un modèle d’équation structurelle exploratoire

IntroductionStudents are at risk for mental health issues due to the COVID-19 pandemic. The implementation of lockdowns as a means to curb the spread of the disease have had an impact on this population, as observed in many international studies. However, few studies have investigated the longitudinal impact of COVID-19 lockdowns on students’ mental health.ObjectiveWe explored the relation between individual characteristics of students, context of life, difficulties in emotion regulation and psychological distress over the first two lockdowns in France during the COVID-19 pandemic.Methodology160 university students (90% female, mean of 24 years old) responded to an online questionnaire at three times points: once during the first lockdown during the COVID-19 pandemic in march 2020, a second time after this lockdown and a third time during the second lockdown. Difficulties in emotion regulation, psychological distress, acute stress, academic concerns, financial resources, and exchanges with professors were measured.ResultsAn exploratory structural equations model was developed to investigate the factors related to psychological distress (χ² = 1459.18, df = 1064, CFI = 0.910, RMSEA = 0.049, SRMR = 0.068). During both lockdowns, psychological distress was explained by academic concerns and lack of emotional clarity and acceptance. An indirect and negative significant relation was identified between financial difficulties, lack of exchanges with professors during the first lockdown, emotion clarity and experienced psychological distress during the second lockdown. Repeated measures ANOVAs identified high levels of acute stress during both lockdowns and a diminution during the deconfinement indicating an impact of sanitary measures on student's mental health.ConclusionCoherently with the Bruchon-Sweiser translational model of stress, emotion regulation capacities seem to have a central and moderating role in the experience of the pandemic for students. They would benefit greatly from appropriate therapeutic interventions in this pandemic situation and in general.     

Testing the stress-buffering effects of self engagement among soldiers on a military operation

The present research examined whether self engagement moderated the stressor-strain relationship in a sample of U.S. soldiers deployed on a peacekeeping mission to Bosnia. Given that individuals were nested within groups (Army companies), we examined the relationships of interest using multilevel random coefficient models. The results of these analyses revealed that self engagement interacted with three different stressors (lower amounts of sleep, work stress, family stress) in the prediction of psychological distress. In support of self engagement as a buffer against stress, when stressors were low (high amounts of sleep, low levels of work stress, and family stress), soldiers reported relatively low levels of psychological distress and physical symptoms, regardless of whether they were engaged in or disengaged from their job. However, when stressor levels were high, soldiers who were engaged in their job reported less elevation in reports of psychological distress than soldiers who were disengaged from their job. The results are discussed in terms of the potential mechanisms by which self engagement might protect individuals from stressful circumstances.     

Parental and family predictors of behavior problems in inner-city black children

Studied contributions of maternal psychological distress, family stress load, maternal and family risk factors, and family coping strategies in predicting behavior problems in 441 inner-city black primary-grade children. Results indicated maternal psychological distress and high family stress load were associated with high child behavior problems. Family coping strategies offered no protection against risk, while coping with life difficulties by reframing them was detrimental to child behavioral adjustment. Active help-seeking strategies (i.e., family mobilization, acquiring social supports) served to moderate the effects of maternal psychological distress and family risk attributes for boys, but exacerbated the effects of dysfunctional maternal social and psychiatric histories for girls. Implications for understanding vulnerability and resilience in inner-city black children and recommendations for future research are discussed.     

Family conflict and academic performance of first-year Asian American undergraduates

This three-study investigation examined risk and protective factors for poor academic performance among Asian American first-year undergraduates. Students were surveyed prior to starting college and their GPA was collected after their first semester in college. Family conflict as a significant risk factor for poor academic performance was examined in all three studies. The results indicate that higher family conflict prior to college was related to lower first-semester college GPA, after controlling for standardized test scores and high school rank (Studies 1-3). Even though psychological distress was related to both family conflict and GPA, it did not mediate the relationship between family conflict and GPA (Studies 2 and 3). In terms of protective factors, the results indicate that life satisfaction buffered the negative effects of family conflict on first-semester college GPA (Study 3). Together, these findings support the need to take into account family variables and psychological well-being in the academic performance of Asian American students as they transition from high school to college.

Moderating factors explaining stress reactions: comparing chronic-without-acute-stress and chronic-with-acute-stress situations

The author compared patterns of moderating factors explaining stress reactions during 2 states: chronic-without-acute-stress and chronic-with-acute-stress. She hypothesized that personal dispositions would contribute more to understanding stress reactions during a prolonged stress state than during an acute state. The participants were Israeli Jewish adolescents living in West Bank settlements during the prolonged (chronic-without-acute-stress) state of the intifada (the Palestinian uprising against Israeli occupation) and during the chronic-with-acute-stress state, immediately after the assassination of Prime Minister Rabin. The author examined 5 variables as moderating factors--trait anxiety, sense of coherence, cognitive appraisal of the political situation, family sense of coherence, and sense of community--and measured 2 stress reactions--state anxiety and psychological distress. Data were collected from 266 8th-grade students during the chronic-without-acute-stress state and 448 students at the same grade level at the chronic-with-acute-stress state. The overall magnitude of variance explanation was different at each state: The author found a relatively high explained variance of state anxiety and psychological distress in the chronic-without-acute-stress situation but not in the chronic-with-acute stress state. These data support the value of developing a model that would recognize the different types of stress situations for moderating the effects of stress.     

Racism experiences and psychological functioning in African American college freshmen: is racial socialization a buffer?

Previous research has documented the negative effects of racism on the psychological health of African Americans. However, consideration of racial socialization as a potential buffer against racism experiences has received limited attention. The present study investigated whether two types of parental racial socialization messages reduced the impact of racism on psychological functioning in a sample of 247 African American college freshmen (M=18.30). Results indicated that students who reported more racism experiences also had poorer levels of psychological functioning as indicated by higher levels of psychological stress and psychological distress. Parental messages emphasizing the use of African American cultural resources to cope with racism reduced the impact of racism on psychological stress only. Cultural pride messages predicted less psychological distress while messages emphasizing the use of cultural resources predicted greater psychological distress. However, neither message type moderated the relationship between racism experiences and psychological distress. These results suggest that racial socialization messages have complex relations to psychological functioning in African American college students.     

Randomized Controlled Trial of a Multilevel Intervention to Address Social Determinants of Refugee Mental Health

Understanding processes that support the well-being of the unprecedented numbers of forcibly displaced people throughout the world is essential. Growing evidence documents post-migration stressors related to marginalization as key social determinants of refugee mental health. The goal of this RCT was to rigorously test a social justice approach to reducing high rates of distress among refugees in the United States. The 6-month multilevel, strengths-based Refugee Well-being Project (RWP) intervention brought together university students enrolled in a 2-semester course and recently resettled refugees to engage in mutual learning and collaborative efforts to mobilize community resources and improve community and systems responsiveness to refugees. Data collected from 290 Afghan, Great Lakes African, Iraqi, and Syrian refugees at four time points over 12 months were used to test the effectiveness of RWP to reduce distress (depression and anxiety symptoms) and increase protective factors (English proficiency, social support, connection to home and American cultures). Intention-to-treat analyses using multilevel modeling revealed significant intervention effects for all hypothesized outcomes. Results provide evidence to support social justice approaches to improving refugee mental health. Findings have implications for refugees worldwide, and for other immigrant and marginalized populations who experience inequities in resources and disproportionate exposure to trauma/stress.     

The interface of identity distress and psychological problems in students’ adjustment to University

Identity distress, psychological symptoms, and adjustment to university (academic, social, and person-emotional) were examined among students in Spain (N = 241; M_age = 19.0 (1.6), Md = 19; 84% female) and Canada (N = 531; M_age = 19.8 (2.2), Md = 19; 82% female). The expected positive relationships were found between these variables. Similarly, increased identity distress of Spanish students and greater maladjustment at university for those in Canada were associated with contextual differences in the respective environments. Psychological problems mediated the linkages between identity distress with academic, social, and person-emotional functioning at university, respectively. Also, psychological problems and context/country were independent predictors of students’ identity distress. Findings underscore the importance of examining contextual factors that influence student adjustment to university in relation to identity development and mental health and they offer suggestions for further research and counseling services.
