Self-reported posttraumatic growth predicts greater subsequent posttraumatic stress amidst war and terrorism

Background and objective: This study tested three alternative explanations for research indicating a positive, but heterogeneous relationship between self-reported posttraumatic growth (PTG) and posttraumatic stress symptoms (PSS): (a) the third-variable hypothesis that the relationship between PTG and PSS is a spurious one driven by positive relationships with resource loss, (b) the growth over time hypothesis that the relationship between PTG and PSS is initially a positive one, but becomes negative over time, and (c) the moderator hypothesis that resource loss moderates the relationship between PTG and PSS such that PTG is associated with lower levels of PSS as loss increases. Design and method: A nationally representative sample (N?=?1622) of Israelis was assessed at three time points during a period of ongoing violence. PTG, resource loss, and the interaction between PTG and loss were examined as lagged predictors of PSS to test the proposed hypotheses. Results: Results were inconsistent with all three hypotheses, showing that PTG positively predicted subsequent PSS when accounting for main and interactive effects of loss. Conclusions: Our results suggest that self-reported PTG is a meaningful but counterintuitive predictor of poorer mental health following trauma.     

The Perceived Stress Scale: Evaluating Configural, Metric and Scalar Invariance across Mental Health Status and Gender

The Perceived Stress Scale (PSS; Cohen, Kamarck, & Mermelstein, Journal of Health and Social Behavior, 24: 385–396, 1983) and its derivatives are among the most commonly used self-report measures of subjective global stress. Several factorial models of the PSS have been proposed; however, which of these structures reliably measures individuals with mental illness remains unclear. Moreover, despite the detection of gender differences in perceived stress, factorial invariance between genders has not yet been tested with the PSS. Confirmatory factor analysis evaluating six prevailing factorial models of the PSS among a large sample of psychiatric patients and a matched community sample supported a two-factor model. Multiple group analysis established configural, metric and scalar invariance of this model across gender, but only configural invariance across samples differing by mental health status. Implications are that gender differences can be cautiously interpreted as true mean differences rather than artifacts of measurement bias; however, mean perceived stress factor scores should not be compared directly across psychiatric and non-psychiatric samples.     

Associations of perceived stress and state anger with symptom burden and functional status in patients with heart failure

Abstract

Background: Psychosocial stress and anger trigger cardiovascular events, but their relationship to heart failure (HF) exacerbations is unclear. We investigated perceived stress and anger associations with HF functional status and symptoms.

Methods and Results: In a prospective cohort study (BETRHEART), 144 patients with HF (77% male; 57.5?±?11.5 years) were evaluated for perceived stress (Perceived Stress Scale; PSS) and state anger (STAXI) at baseline and every 2 weeks for 3 months. Objective functional status (6-min walk test; 6MWT) and health status (Kansas City Cardiomyopathy Questionnaire; KCCQ) were also measured biweekly. Linear mixed model analyses indicated that average PSS and greater than usual increases in PSS were associated with worsened KCCQ scores. Greater than usual increases in PSS were associated with worsened 6MWT. Average anger levels were associated with worsened KCCQ, and increases in anger were associated with worsened 6MWT. Adjusting for PSS, anger associations were no longer statistically significant. Adjusting for anger, PSS associations with KCCQ and 6MWT remained significant.

Conclusion: In patients with HF, both perceived stress and anger are associated with poorer functional and health status, but perceived stress is a stronger predictor. Negative effects of anger on HF functional status and health status may partly operate through psychological stress.     

Psychometric evaluation and normative data of the Swedish version of the 10‐item perceived stress scale

The perceived stress scale (PSS) has been translated to several languages and validated in many cultures. The longer 14‐item version (PSS‐14), has been translated to Swedish and validated for Swedish use. However, the Swedish version of the shorter 10‐item version (PSS‐10) has not been validated before. Therefore, the aim of this study was to evaluate the Swedish version of the PSS‐10 with regard to reliability and validity, and to provide normative data. Data from 3,406 individuals who took part in the Västerbotten Environmental Health Study in Sweden were used. The respondents constitute a random sample, aged 18 to 79 years, and stratified for age and sex. They responded to the Swedish version of the PSS‐10 as well as to the hospital anxiety and depression scale, and the Shirom Melamed burnout questionnaire for assessment of construct validity. The results show that the PSS‐10 provides approximately normally distributed data, has good internal reliability (Cronbach's alpha 0.84), and has good construct validity with anxiety (r = 0.68), depression (r = 0.57), and mental/physical exhaustion (r = 0.71). The favorable psychometric properties of the Swedish version of the PSS‐10 suggest use of the instrument for assessing perceived stress in Swedish and similar populations.     

Increased perceived stress is associated with blunted hedonic capacity: potential implications for depression research

Preclinical studies suggest that stress exerts depressogenic effects by impairing hedonic capacity; in humans, however, the precise mechanisms linking stress and depression are largely unknown. As an initial step towards better understanding the association between stress and anhedonia, the present study tested, in two independent samples, whether individuals reporting elevated stress exhibit decreased hedonic capacity. The Perceived Stress Scale (PSS) measured the degree to which participants appraised their daily life as unpredictable, uncontrollable, and overwhelming. Hedonic capacity was objectively assessed using a signal-detection task based on a differential reinforcement schedule. Decreased reward responsiveness (i.e., the participants' propensity to modulate behavior as a function of reward) was used as an operational measure of hedonic capacity. In both Study 1 (n=88) and Study 2 (n=80), participants with high PSS scores displayed blunted reward responsiveness and reported elevated anhedonic symptoms. Additionally, PSS scores predicted reduced reward responsiveness even after controlling for general distress and anxiety symptoms. These findings are consistent with preclinical data highlighting links between stress and anhedonia, and offer promising insights into potential mechanisms linking stress to depression.     

Perceived stress,life events,dysfunctional attitudes,and depression in adolescent psychiatric inpatients

Hewitt, Flett, and Mosher (1992) examined the factor structure of the Perceived Stress Scale (PSS) and its relation to depression in adult psychiatric patients. This study sought to replicate and extend their findings, using a sample of 203 adolescent psychiatric inpatients. All patients admitted to the adolescent unit in a psychiatric hospital over a 3-year period were administered the PSS, as well as measures of depression, life events, dysfunctional attitudes, and intellectual abilities. Consistent with Hewittet al., two factors were found in the PSS, reflecting perceived distress and perceived coping ability. Regression analyses indicated that, for males, both factors account for independent variance in depression, whereas for females, only the distress factor is related to depression. In addition, for both male and female, dysfunctional attitudes account for significant variance in depression in addition to PSS, but negative life events do not. None of the variables were related to intellectual abilities. Implications for clinical assessment and intervention are discussed.     

The Perceived Stress Scale: Factor structure and relation to depression symptoms in a psychiatric sample

The present study sought to examine the factor structure and psychometric properties of the Perceived Stress Scale (PSS) when administered to psychiatric patients. We also examined predictive validity of the PSS by assessing the association between the Perceived Stress Scale and the Beck Depression Inventory. A heterogeneous sample of 96 psychiatric patients (48 men, 48 women) completed the Perceived Stress Scale (PSS) and the Beck Depression Inventory. Factor analysis of the PSS established that the scale consisted of two factors. The first factor was comprised primarily of items reflecting adaptational symptoms. In contrast, the second factor consisted of items reflecting coping ability. Both factors had an adequate degree of internal consistency. Finally, a series of regression analyses predicting depression found that both factors accounted for unique variance in depression scores in women, but only the first factor accounted for unique variance in men. It is concluded that the PSS is a multidimensional and internally consistent measure of perceived stress.This research was supported by Grant 410-91-1690 from the social sciences and Humanities Research Council of Canada as well as by grants from the Research and Program Evaluation Committee Brockville Psychiatric Hospital.

Work addiction is associated with increased stress and reduced quality of life: Validation of the Bergen Work Addiction Scale in Danish

Addiction to work is defined as a compulsion or an uncontrollable need to work incessantly. Only few measures exist to identify work addiction and the health consequences are sparsely explored. The Bergen Workaholic Scale (BWAS) measures seven core elements of work addiction and has been used in Norway, Hungary, Brazil, Italy, USA and Poland. The aim of this study was to validate the BWAS in a Danish sample and to investigate if high risk of work addiction was associated with stress and reduced quality of life. We conducted an online screening survey with 671 participants aged 16–68 years with the Danish translation of the BWAS. We added the perceived stress scale (PSS) and the quality of life scale EQ‐5D‐5L. Those with high risk of work addiction reported significantly higher mean PSS scores (20.0 points) compared to those with low risk of addiction (12.5 points) and poorer quality of life (61.9) compared to the low risk group (81.3). Furthermore, work addiction was associated with more weekly working hours (44.0 vs. 35.6 hours/week) and having more leadership responsibility. A preliminary estimate of work addiction prevalence was 6.6%. The BWAS demonstrated good reliability (α = 0.83), and factor analyses pointed at a single factor structure. Work addiction seems to be associated with health problems in terms of stress and poorer quality of life. The BWAS is recommended as a reliable and valid tool to identify work addiction in Danish.     

Chronic self-perceived stress and set-shifting performance in undergraduate students

Given recent findings on the potential for detrimental effects of chronic stress on the prefrontal cortex, additional research on the relationship between chronic stress and performance on executive functioning tasks (dependent on prefrontal functioning) is needed. Eighty-one undergraduate students completed a self-report measure of stress over the previous month (perceived stress scale--PSS) and the comprehensive trail-making test (CTMT, Trials 3 and 5). Results revealed a statistically significant positive correlation between PSS score and time needed to complete Trial 5 of the CTMT, which places demands on the set-shifting component of executive functioning. This finding adds to a growing body of work that suggests a relationship between chronic stress and executive functioning, and extends these findings to include set-shifting performance.     

Typological and factor analysis of the perceived stress measure by using the PSS scale

The aim of this research was to explore the structure of the Perceived Stress Scale (PSS) by using data analysis in order to question its theoretical and methodological bases in a critical and positive way. Unidimensional analyses and two-dimensional analyses of the scale were carried out on a sample of 600 individuals. The typological analysis of the data subsequently made it possible to cross these two analyses and revealed that the individuals who have average stress (45% of the sample) according to the traditional measure of the PSS, had very diversified profiles according to the two-dimensional analysis. Some of these profiles are not in accordance with the basic model of a discrepancy between perceived control and perceived distress. In light of the results obtained, this precise typology could be useful in the field for carrying out audits and surveys while offering new elements of observation likely to improve psychosocial interventions.     

Posttraumatic Stress in Survivors of Childhood Cancer and Mothers: Development and Validation of the Impact of Traumatic Stressors Interview Schedule (ITSIS)

This study presents initial data validating the use of a new instrument, the Impact of Traumatic Stressors Interview Schedule (ITSIS), to assess the occurrence of cancer-related posttraumatic stress in childhood cancer survivors and their mothers. Sixty-six child/adolescent cancer survivors and 64 of their mothers, as well as 130 young adult survivors, completed the ITSIS and other measures of posttraumatic stress and general distress. Five ITSIS factors were identified for the mothers and for the young adult survivors, and three ITSIS factors were identified for the child/adolescent survivors. Factors in all three samples reflected symptoms of posttraumatic distress, concern over medical late effects, communication, and changes in self due to cancer. Only young adult survivors had a factor reflecting a positive engagement with the cancer history. Factors correlated with validation measures in predicted ways. The findings further the conceptualization of posttraumatic stress in pediatric cancer by describing the traumatic experience for survivors and mothers. Comparing factors across samples allows an examination of different influences of cancer within families and over the course of development.     

Factor structure of the Perceived Stress Scale (PSS) in a sample from Mexico

The aim of this study was to analyze the cultural adaptation of the European Spanish version of the Perceived Stress Scale (PSS; Cohen, Kamarak, & Mermelstein, 1983), for its use in Mexican samples. Using a random sample of students, internal consistency was analyzed and the factor structure of the Spanish version of the PSS was compared with the factor structure found in the English version. Internal consistency was adequate (alpha = .83) and confirmatory factor analysis corroborated the factor structure. Factor 1 explained 42.8% of the variance and Factor 2 accounted for 53.2%. The goodness-of-fit measures also revealed an adequate fit. The cultural adaptation of the PSS was also evaluated with satisfactory results.     

Validation of the Poisoning Severity Score (PSS) in suicidal behavior by self‐poisoning

Intentional self‐poisoning is the leading method of suicidal behavior leading to medical attention worldwide. The medical severity of self‐poisoning events has major treatment, prognostic, and medico‐legal implications, yet measures of severity are limited. The Poisoning Severity Score (PSS) is a widely used scale but validation data are limited, particularly in the study of suicidal behavior per se. The sample was a consecutive series of intentional self‐poisoning patients aged 13 to 65 treated at a large university medical center (n = 673). PSS scores, with a range 0 (none) to 4 (death), were calculated along with other structured clinical data and analyzed in a series of linear regressions adjusted for age and sex. Higher PSS scores were consistently associated with greater medical morbidity and more intensive acute medical treatments, and nearly all effect sizes were large. Results support the validity of the PSS in hospital‐treated self‐poisoning patients.     

术后乳腺癌患者体象对创伤后应激障碍和创伤后成长的影响：反刍的中介作用

为探讨乳腺癌患者反刍这一认知情绪调节方式在体象和创伤后应激障碍（PTSD）、创伤后成长（PTG）之间的中介作用,采用体象量表（BIS）、认知情绪调节问卷中文版（CERQ-C）、创伤后应激障碍量表（PSS）和创伤后成长问卷（PTGI）对150名乳腺癌术后患者进行研究。结果发现：（1）乳腺癌患者的体象可以正向预测PTSD和PTG;（2）乳腺癌患者的反刍在体象和PTSD的闯入性症状、回避性症状中起中介作用,在体象与PTG中的中介作用不显著。结果表明,体象既可以正向预测乳腺癌患者的PTSD和PTG,也可以通过反刍的中介作用影响PTSD。     

Caudate nucleus-dependent response strategies in a virtual navigation task are associated with lower basal cortisol and impaired episodic memory

The present research examined the relationship between endogenous glucocorticoids, navigational strategies in a virtual navigation task, and performance on standard neuropsychological assessments of memory. Healthy young adult participants (N = 66, mean age: 21.7) were tested on the 4 on 8 virtual maze (4/8 VM) and standard neuropsychological tests such as the Rey-Osterrieth Complex Figure (RO) and the Rey Auditory Verbal Learning Task (RAVLT), which measure episodic memory. The 4/8 VM differentiates between navigational strategies, where participants either use a hippocampal-dependent spatial strategy by building relationships between landmarks, or a caudate nucleus-dependent stimulus–response strategy by automatizing a pattern of open and closed arms to learn the location of objects within the maze. Degree of stress was assessed by administering the Perceived Stress Scale (PSS) questionnaire. Cortisol samples were taken on two consecutive days upon waking, 30 min after waking, at 11 am, 4 pm, and 9 pm. There was a significant difference in basal levels of cortisol between spatial and response learners. Interestingly, response learners had significantly lower cortisol levels throughout the day. The two groups did not differ in terms of perceived stress as measured with the PSS questionnaire. Moreover, there was no significant correlation between PSS scores and salivary cortisol levels, indicating that the higher cortisol levels in the spatial group were not associated with greater perceived stress. In addition, participants who spontaneously used a spatial strategy performed significantly better on the RAVLT and RO. These data indicate that the cortisol levels in the spatial group may be optimal in terms of episodic memory performance whereas the cortisol levels in the response group may be associated with poorer memory. These results are suggestive of an inverted U-shaped curve describing the effects of basal levels of circulating cortisol on memory in young adults.

Perceived Organizational Support and Turnover Intention: The Mediating Effects of Personal Sacrifice and Job Fit

ABSTRACT

This study examines the mediating role of job fit on the relationship between perceived supervisor support (PSS) and perceived organizational support (POS), and the mediating role of personal sacrifice on the relationship between POS and turnover intention. We use structural equation modeling (SEM) with a data set consisting of a sample of 346 individuals in a manufacturing firm to test our proposed model of PSS, POS, and turnover intention. Consistent with prior literature, our hypothesized model confirms that PSS is a predictor of POS and that POS is a predictor of turnover intention. By testing two additional competing and theoretically derived nested models, our findings indicate that job fit partially mediates the relationship between PSS and POS, and that personal sacrifice partially mediates the relationship between POS and turnover intention. Our study is among the first to examine job fit and personal sacrifice as mediators within the POS-turnover intention model.     

Post-traumatic stress disorder symptoms of children following the occurrence of Tehran City Park disaster

The authors investigated the post-traumatic stress disorder (PTSD) symptoms of young adolescents who had been directly involved in a disaster in Tehran. The participants were 19 chlidren who had survived a boat sinking in Tehran's city park in 2002. By using the Post-Traumatic Stress Disorder Symptom Scale (PSS; E. B. Foa, D. S. Riggs, C. V. Dancu, & B. O. Rothbaum, 1993) as well as a clinical interview based on the definition cited in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994, p. 424), 16 participants (84.2%) were diagnosed with PTSD using the PSS and 17 (89.5%) were diagnosed with PTSD using the psychiatric interview.     

A Spanish adaptation of the Parental Stress Scale

As a specific measure to assess levels of parental stress is lacking in Spain, the aim of this study was to develop the Spanish version of the Parental Stress Scale (PSS). After translating it from English into Spanish using the forward-backward translation method, it was administered to a sample of 211 first-time parents (105 males and 106 females). A factor analysis was carried out to assess its dimensionality. After refining the scale, we obtained a two-factor solution that accounted for 33.5% of the variance, with the factors Stressors and Parenting Rewards. No gender differences were found either in the scale or in the dimensions. Criterion-related validity was tested by means of correlations with anxiety and depressive symptoms and, with regard to internal consistency, adequate alpha coefficients were obtained for both factors.
