Ecological momentary assessments (EMA) of anxiety and anger/hostility were obtained every 25–30 min over two 24-h periods, separated by a median of 6 months, from 165 employees at a university in the Northeast. We used a multilevel trait-state-error structural equation model to estimate: (1) the proportion of variance in EMA anxiety and anger/hostility attributable to stable trait-like individual differences; (2) the correspondence between these trait-like components of EMA anxiety and anger/hostility and traditional questionnaire measures of each construct; and (3) the test–retest correlation between two 24-h averages obtained several months apart. After adjustment for measurement error, more than half the total variance in EMA reports of anxiety and anger/hostility is attributable to stable trait-like individual differences; however, the trait-like component of each construct is only modestly correlated with questionnaire measures of that construct. The 6-month “test–retest” correlations of latent variables representing the true 24-h EMA average anxiety and average anger are quite high (r ? 0.83). This study represents the longest follow-up period over which EMA-based estimates of traits have been examined. The results suggest that although the trait component (individual differences) of EMA momentary ratings of anxiety and anger is larger than the state component, traditional self-report questionnaires of trait anxiety and anger correspond only weakly with EMA-defined traits.  相似文献

The present study examined the validity and reliability of the parent-report version of Carver and White's BIS/BAS-scales for children, measuring Punishment and Reward Sensitivity (PS and RS). Gender and age differences in PS and RS were explored. Mothers (n = 546, 62% girls, 2–18 years) completed the BIS/BAS parent-version and other instruments assessing PS/RS, personality and psychopathology. Reliability of most (sub-)scales was at least acceptable. The BIS/BAS-scales had meaningful relationships with other instruments assessing PS/RS, personality and psychopathology. There were significant age differences on BIS/BAS-scores, but no significant gender differences. The BIS/BAS parent-version is a valid and reliable parent-report PS/RS instrument for children and adolescents.  相似文献

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n = 104, Mage = 22.25, SD = 3.42; 50% Female) used a between-subjects 2 × 2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p < 0.001, Cohen’s d effect size = 0.89), and goal-EFT was more effective than general-EFT on reducing DD (p = 0.03, d = 0.64).  相似文献

Maternal self-confidence has become an essential concept in understanding early disturbances in the mother-child relationship. Recent research suggests that maternal self-confidence may be associated with maternal mental health and infant development. The current study investigated the dynamics of maternal self-confidence during the first four months postpartum and the predictive ability of maternal symptoms of depression, anxiety, and early regulatory problems in infants. Questionnaires assessing symptoms of depression (Edinburgh Postnatal Depression Scale), anxiety (State-Trait Anxiety Inventory), and early regulatory problems (Questionnaire for crying, sleeping and feeding) were completed in a sample of 130 women at three different time points (third trimester (T1), first week postpartum (T2), and 4 months postpartum (T3). Maternal self-confidence increased significantly over time. High maternal trait anxiety and early infant regulatory problems negatively contributed to the prediction of maternal self-confidence, explaining 31.8% of the variance (R = .583, F3,96 = 15.950, p < .001).Our results emphasize the transactional association between maternal self-confidence, regulatory problems in infants, and maternal mental distress. There is an urgent need for appropriate programs to reduce maternal anxiety and to promote maternal self-confidence in order to prevent early regulatory problems in infants.  相似文献

Reinforcement Sensitivity Theory (RST), the original (i.e. Gray, 1982) or revised (Gray & McNaughton, 2000), has yet to be used as a framework for investigating vulnerability to Major Depressive Disorder (MDD) in adolescents. The present study employed a high-risk design to examine whether aberrant BIS-FFFS/BAS activity was similarly present in both depressed girls and girls at high risk for depression.MethodsN = 85 age-matched biological daughters of mothers with differential MDD status: (a) MDD (n = 17), (b) high-risk (n = 34), and (c) healthy controls (n = 34) completed measures of the BIS/BAS, depression, and anxiety.ResultsMDD girls scored significantly higher on BIS than healthy controls but not high-risk girls, and the high-risk and control groups did not differ. No group differences were found on BAS or FFFS-Fear.ConclusionsElevated BIS was not identified as a vulnerability factor for MDD; however, it does distinguish depressed adolescents from healthy controls.  相似文献

IntroductionDespite numerous studies on the association between headache and psychological difficulties in children, the results remain inconclusive.ObjectiveThis cross-sectional study was conducted to clarify the links between anxiety-depression and headache in children. We evaluated the levels of anxious and depressive symptoms and the influence of risk factors: age, sex, headache diagnosis, frequency and history to identify and treat headache sufferers most at risk.MethodData were collected from a clinical sample of 368 children aged 8 to 17 years. First, a structured interview using the International Classification of Headache Disorders (ICHD-II) was used to diagnose 88 patients with migraine (M), 32 with tension-type headache (TTH), and 248 with a combination syndrome (M + TTH). Second, levels of anxiety and depressive symptoms were assessed with the Revised Children's Manifest Anxiety Scale (R-CMAS) and the Multiscore Depression Inventory for Children (MDI-C).ResultsAn ANOVA analysis showed that the mean scores for anxiety and depressive symptom levels were significantly higher among older patients and that only the M + TTH diagnosis was significantly associated with anxiety. Children with clinically significant levels of anxiety symptoms were more prevalent in our sample than in the general population (13% versus 5%). Anxiety and depression were not associated with child sex, headache frequency and history.ConclusionWe propose systematic screening for anxiety in children presenting with headache, particularly adolescents and patients with a combination diagnosis.  相似文献

ObjectiveQuestionnaires are often applied in sports psychology to measure a person's trait or state. However, the extent to which the questionnaire captures differences because of trait or state influences is often unclear. The latent state–trait (LST) theory offers the opportunity to separate both variance sources. This separation allows estimating specific reliability coefficients.DesignThe present paper gives a theoretical introduction to LST and its basic ideas. Using a real data set with N = 156 athletes we exemplify the steps necessary to derive the LST coefficients. All athletes filled out a comprehensive inventory assessing competitive anxiety on two occasions.MethodThe data are analysed with structural equation models based on LST principles.ResultsThe results confirm the questionnaire's trait saturation.ConclusionFinally, results are discussed in light of practical and theoretical implications.  相似文献

Although worry is central to the diagnosis of generalized anxiety disorder (GAD), it is also commonly observed in other anxiety disorders. In this meta-analytic review, we empirically evaluated the extent to which worry is specific to GAD relative to patients with other anxiety disorders, those with other psychiatric disorders, and nonpsychiatric controls. A total of 47 published studies (N = 8,410) were included in the analysis. The results yielded a large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among anxiety disorder patients v. nonpsychiatric controls (d = 1.64). In contrast to the many differences emerging from comparisons between anxiety disordered patients and nonpsychiatric controls, when anxiety disordered patients were compared to people with other psychiatric disorders they differed only on severity/frequency and not on meta-worry or domains of worry. A large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among patients with GAD v. nonpsychiatric controls was also found (d = 2.05). However, differences between GAD and those with other psychiatric disorders also emerged for severity/frequency of worry. GAD was associated with greater worry difficulties than other anxiety disorders, which generally did not differ from those with other psychiatric disorders and each other. The implications of these findings for conceptualizing worry in GAD and other anxiety disorders, and the potentially moderating effects of age and gender are discussed.  相似文献

Research into the influence of affect on impulse buying has to date produced contradictory results, partly due to confusion between the potentially discrete influences of, respectively, state and trait affect. Additionally, studies on how the five-factor personality model’s dimensions influence impulse buying have also produced contradictory results. Moreover, while the established link between trait affect and personality suggests dimensions of this latter could account for whatever influence the former has on impulse buying, no study has yet attempted to examine this possibility. We draw on self-regulation theory to examine three unanswered questions: (1) the extent to which trait affect influences impulse buying whilst controlling for state affect; (2) establish which dimensions of the five-factor personality model predict impulse buying; and (3) test whether or not any influence of trait affect on impulse buying is additive to the effects of the five-factor personality model. Analyses of cross-sectional data (n = 842) find that trait affect does have a significant (p < .05) influence on impulse buying controlling for state affect, but that this influence is fully accounted for by the five-factor personality model (p < .001), the extraversion, conscientiousness and neuroticism dimensions of which are found consistently to predict impulse buying.  相似文献

IntroductionCannabis is the most commonly used illicit drug with the highest prevalence reported among 15- to 24-year-olds. This specific period of emerging adulthood constitutes a critical age for substance use and for future consumption. Cannabis use patterns change during college or university and the post-college transition; users are at greater risk of adverse health outcomes (especially if they start or maintain a pattern of frequent use).ObjectivesThe overall aim of this study was to highlight psychological and relational factors that might be associated with changes (including cessation and fluctuation) in cannabis use during this specific period, separately for males and females.MethodsThe subjects were 682 first-year college students (69.94% of female), aged between 18 and 25 years (M = 18.59 years, SD = 1.56). Four groups were formed according to cannabis consumption: “non-users” (54.64%), “desisting users” (14.04%), “fluctuating users” (16.23%), and “persistent users” (15.07%). A self-report questionnaire was administered to evaluate prevalence, frequency and trajectory of use, number of peer cannabis users, alcohol use, impulsivity, anxiety (trait and social) and depression.ResultsFemales appear more sensitive to the romantic partner's consumption than males. For both sexes, having more friends who use cannabis appears to be a determinant. Depression and anxiety were not related to changes in cannabis use. Impulsivity is a significant factor for the maintenance of cannabis use in emerging adulthood, with higher lack of premeditation for males and higher sensation seeking for females among fluctuating and persistent users.ConclusionsResults are discussed in terms of maintenance of use and the spiral of consumption, including clinical implications for prevention and interventions.  相似文献

Social anxiety and eating pathology frequently co-occur. However, there is limited research examining the relationship between anxiety and body checking, aside from one study in which social physique anxiety partially mediated the relationship between body checking cognitions and body checking behavior (Haase, Mountford, & Waller, 2007). In an independent sample of 567 college women, we tested the fit of Haase and colleagues’ foundational model but did not find evidence of mediation. Thus we tested the fit of an expanded path model that included eating pathology and clinical impairment. In the best-fitting path model (CFI = .991; RMSEA = .083) eating pathology and social physique anxiety positively predicted body checking, and body checking positively predicted clinical impairment. Therefore, women who endorse social physique anxiety may be more likely to engage in body checking behaviors and experience impaired psychosocial functioning.  相似文献

Psychological processes may influence balance and contribute to the risk of falls in older people. While a self-reported fear of falling is associated with increased postural sway, inducing fear using an elevated platform can lead to reduced sway, suggesting different underlying mechanisms whereby fear may influence balance control. This study examined changes in postural sway, muscle activity and physiological measures of arousal while standing on a 65 cm elevated platform, compared to floor level, in young and older adults. The older adults were classified as fall concerned or not fall concerned based on the Falls Efficacy Scale-International and anxious or not anxious based on the Goldberg Anxiety Scale. Fall concern did not affect the physiological and sway response to the elevated platform. In response to the postural threat, the anxious participants increased their sway frequency (p = 0.001) but did not reduce sway range (p = 0.674). Conversely, non-anxious participants showed an adaptive tightening of balance control, effectively reducing sway range in the elevated condition (p < 0.001). Generalised anxiety in older adults appears to differentially affect postural control strategies under threatening conditions.  相似文献

Previous studies suggest that self-compassion is related to numerous facets of mental health, but the role of cognitions in this relationship remains unknown. To examine the mediating role of cognitions in the relationship between self-compassion and anxiety, depression, and life satisfaction when controlling for self-esteem in Japanese people, we conducted two studies. Study 1 (N = 231) examined the relationship between self-compassion and affect by modeling negative automatic thoughts as a mediator; Study 2 (N = 233) tested whether positive and negative automatic thoughts meditate this relationship. Results suggested that both self-compassion and self-esteem increased positive automatic thoughts and decreased trait anxiety, whereas only self-esteem increased life satisfaction and decreased depression directly. Positive automatic thoughts increased life satisfaction and decreased depression and trait anxiety, and positive automatic thoughts mediated the relationship between self-compassion and negative affect. These findings suggest that both positive and negative automatic thoughts mediate the relationship between self-compassion and affect in Japanese people.  相似文献

The extent to which visual function, measured as near and distant visual acuity and contrast sensitivity, is correlated with concurrently measured cognitive function and prior intellectual ability was investigated in a narrow age range group known as the Lothian Birth Cohort of 1921 (LBC1921). Participants were aged ~ 83 years at the time of testing (N = 321). A well-fitting structural equation model highlighted a significant contribution of a latent visual trait to a general fluid intelligence factor in old age, independent of the contribution from childhood intelligence. Additionally, childhood intelligence made a significant contribution to the general visual factor in old age. However, the model fitted equally well when the fluid intelligence factor is assumed to be a cause of the visual function latent trait, in which case childhood intelligence does not significantly influence vision in old age. We discuss these results with respect to four possible mechanisms by which vision and cognition can come to be correlated over the lifecourse.  相似文献

Accumulating evidence suggests that antenatal depression predicts infants’ negative affectivity, albeit with variable effect sizes. With a prospective longitudinal design, we sought to explain that variability by addressing questions about timing of the depression across pregnancy and the early postpartum, the role of high symptom levels relative to diagnosed depression, comorbidity with anxiety, and the potential mediating role of neuroendocrine functioning. Primiparous women (n = 77) with histories of depression prior to pregnancy were assessed for cortisol levels monthly beginning by mid-pregnancy. Depression symptom levels and diagnostic status were similarly assessed monthly in pregnancy and also until infants reached three months of age, when mothers completed the Infant Behavior Questionnaire-Revised to measure infant negative affectivity. Antenatal depression symptoms and infant negative affectivity were positively associated (r = .39). Controlling for depression symptom levels in other trimesters, only second trimester depression symptoms predicted higher infant negative affectivity (β = .44). With postpartum depression symptom levels in the model, only antenatal depression symptoms predicted infant negative affectivity (β = .45). In the context of depression, neither antenatal anxiety symptoms nor anxiety disorder diagnosis were associated with infant NA scores. The hypothesized role of elevated maternal cortisol as a mechanism for the association between antenatal depression and infant NA was not supported. Our findings contribute to efforts to more precisely identify infants of perinatally depressed mothers who are at greater risk for elevated negative affectivity, suggesting a window of vulnerability in mid pregnancy and the need for further study of potential mechanisms.  相似文献

Several studies have observed heightened Pavlovian fear conditioning in PTSD. However, it is unclear how fear conditioning in PTSD is related to risk factors for the disorder, such as anxiety sensitivity. Fifty-one combat-exposed veterans (20 with PTSD, 31 without PTSD) completed a differential fear conditioning task in which one colored rectangle (CS +) predicted a loud scream (US), whereas a different colored rectangle (CS-) predicted no US. Veterans with PTSD were characterized by greater anxiety to the CS + but not the CS- during acquisition and extinction, and greater US expectancy during the CS + but not the CS- at extinction. Also, veterans with PTSD had greater pupil dilation to both CSs at extinction, but not at acquisition. Anxiety sensitivity was correlated with anxiety and US expectancy in response to the CS +, but not the CS-, at both acquisition and extinction, and also with pupil diameter to both the CS + and CS- at extinction. Nearly all of these relations held when covarying for PTSD symptoms and trait anxiety. These findings suggest that increased fear conditioning in PTSD may be related to elevated anxiety sensitivity.  相似文献

Background/ObjectiveThe Short Health Anxiety Inventory (SHAI) is a widely used self-report instrument to evaluate health anxiety. To assess the SHAI's factor structure, psychometric properties, and accuracy in differentiating Spanish non-clinical individuals from patients with severe health anxiety or hypochondriasis.MethodA total of 342 community participants (61.6% women; Mage = 34.60, SD = 14.91) and 31 hypochondriacal patients (51.6% women; Mage = 32.74, SD = 9.69) completed the SHAI and other self-reports assessing symptoms of hypochondriasis, depression, anxiety sensitivity, worry, and obsessive-compulsive.ResultsThe original two-factor structure was selected as the best structure, based on its parsimony and empirical support (Factor 1: Illness likelihood; Factor 2: Negative consequences of illness). Moreover, the Spanish version of the SHAI demonstrated good construct and concurrent and discriminant validity, and internal consistency. A cutoff of 40.5 (total score) accurately distinguished non-clinical individuals from patients with severe health anxiety or hypochondriasis.ConclusionsThe SHAI is an adequate screening instrument to measure health anxiety in Spanish-speaking community adults.  相似文献

PurposeThe purpose of this study was to evaluate anxiety and psychological functioning among adolescents seeking speech therapy for stuttering using a structured, diagnostic interview and psychological questionnaires. This study also sought to determine whether any differences in psychological status were evident between younger and older adolescents.MethodParticipants were 37 stuttering adolescents seeking stuttering treatment. We administered the Computerized Voice Version of the Diagnostic Interview Schedule for Children, and five psychometric tests. Participants were classified into younger (12–14 years; n = 20) and older adolescents (15–17 years; n = 17).ResultsThirty-eight percent of participants attained at least one diagnosis of a mental disorder, according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; APA, 2000), with the majority of these diagnoses involving anxiety. This figure is double current estimates for general adolescent populations, and is consistent with our finding of moderate and moderate–severe quality of life impairment. Although many of the scores on psychological measures fell within the normal range, older adolescents (15–17 years) reported significantly higher anxiety, depression, reactions to stuttering, and emotional/behavioral problems, than younger adolescents (12–14 years). There was scant evidence that self-reported stuttering severity is correlated with mental health issues. There are good reasons to believe these results are conservative because many participants gave socially desirable responses about their mental health status.DiscussionThese results reveal a need for large-scale, statistically powerful assessments of anxiety and other mental disorders among stuttering adolescents with reference to control populations.Educational Objectives: The reader will be able to: (a) explain the clinical importance of assessing for mental health with stuttering adolescents, (b) state the superior method for adolescent mental health assessment and (c) state a major issue with determining the genuineness of stuttering adolescent responses to psychological assessment.  相似文献

Despite previous studies of psychopathy and the motivational systems of the Reinforcement Sensitivity Theory (RST) of personality, few have examined psychopathy in light of the revised RST model. In a large sample (N = 779) of young adults, we expand on Hughes, Moore, Morris, and Corr’s (2012) preliminary findings relating primary/secondary psychopathy to revised RST’s three systems: Flight-Flight-Freeze System (FFFS), Behavioral Inhibition System (BIS), and Behavioral Approach System (BAS). Converging results between Hughes et al. and the current study emphasize three major findings: (1) primary psychopathy is negatively related to the BIS as well as the FFFS; (2) primary psychopathy is positively related to goal-driven behavior of the BAS; and, (3) secondary psychopathy is positively related to impulsivity reflected in the BAS. The FFFS was incrementally predictive of primary but not secondary psychopathy. No evidence for a BAS × BIS interaction in psychopathy was found. Results are discussed in terms of future research directions.  相似文献

This study sought to examine the relationships between stereotypically masculine (instrumentality) and feminine (expressiveness) personality traits, social anxiety and depressive symptoms, and three interpersonal styles of relating: destructive overdependence (DO), dysfunctional detachment (DD), and healthy dependence (HD). Based on theories of social anxiety and recent research on social anxiety and close relationships, it is argued that individuals with higher levels of social anxiety would display greater detachment and overdependence in their interpersonal relationships. Students at an Australian university (n = 524) completed a battery of online self-report measures. The findings suggest that low levels of instrumentality are related to social anxiety and depressive symptoms, which both mediate the relationship between instrumentality and the two maladaptive interpersonal styles of relating: DO and DD.  相似文献
