Normal aging dampens the link between intrusive thoughts and negative affect in reaction to daily stressors

We charted daily variations in intrusive thoughts to gain access to adult age differences in affective reactivity to daily stressors. On 100 days, 101 younger and 103 older adults reported stressors, intrusive thoughts, and negative affect. Although increments in intrusive thoughts were similar in both age groups on days with stressors, older adults' negative affect increased less than younger adults' on such days. In addition, (a) levels of intrusive thoughts and negative affect across study time were positively associated; (b) days with increased thoughts were days with increased negative affect; and (c) experiencing above-average intrusive thoughts about stressors strengthened affective reactions to stress. Relative to younger adults, all three associations were reduced in older adults. We tentatively conclude that normal aging dampens the stress-induced link between intrusive thoughts and affect. This dampening may contribute to preserved affective well-being and reduced affective reactivity to daily stress in old age.     

BRIEF REPORT: Intrusive Thoughts and Intrusive Memories in a Nonclinical Sample

We investigated the relative frequency and aversiveness of intrusive thoughts and memories by eliciting the five most common of each in a mixed-sex nonclinical sample. Intrusive memories were a common phenomenon, although not as common as intrusive thoughts. When memories were elicited first, memories and thoughts were rated as equally pleasant, but thoughts were related as more unpleasant when they were elicited first. The most intrusive memory was associated more often with sadness and happiness, whereas the most intrusive thought was associated more often with fear.     

Trait Versus Task-Induced Emotional Reactivity and Distress Intolerance in Hoarding Disorder: Transdiagnostic Implications

Evidence from analogue samples suggests that deficits in emotional functioning, namely elevated emotional reactivity and distress intolerance, are implicated in the development and maintenance of hoarding disorder. We aimed to extend previous research in this area by investigating emotional reactivity and distress intolerance in a sample of individuals diagnosed with hoarding disorder (n = 24) in comparison to clinical controls (n = 21) and nonclinical community controls (n = 26) using a combination of self-report, physiological, and behavioral measures. We found that trait distress intolerance was significantly and independently associated with greater hoarding severity. The hoarding and clinical control groups reported more trait emotional reactivity and distress intolerance than the community control group, but did not differ from each other on these traits. The hoarding group reported more subjective distress before beginning a frustrating behavioral task, but did not evidence more physiological arousal. Moreover, the hoarding group experienced similar increases in distress during the task and did not differ from either group in regard to time persisting on this task. The clinical control group, however, terminated the frustrating task significantly faster than the community control group, who tended to persist until the task timed out. Lastly, trait distress intolerance evidenced a small-to-moderate but nonstatistically significant independent relationship with task persistence time. Given the desynchrony between subjective distress and physiological arousal, we encourage researchers to utilize multimodal assessment in the future. We also suggest that clinicians start to use behavioral experiments, as has been done with other psychological disorders, to improve distress intolerance among persons who experience hoarding disorder.     

A comparison of thought suppression to an acceptance-based technique in the management of personal intrusive thoughts: a controlled evaluation

Research suggests that suppressing unwanted thoughts is not possible, leads to a subsequent increase in frequency of the suppressed thoughts, and results in higher levels of distress. Because thought suppression may have negative effects, an alternative, acceptance-based approach has been proposed. The current paper reports the outcomes of two studies. Study I examined the relationships between two naturally occurring strategies of thought management (thought suppression and acceptance), symptoms of psychopathology, and experiences with personally relevant intrusive thoughts. Results showed that those who naturally suppress personally relevant intrusive thoughts have more, are more distressed by, and have a greater "urge to do something" about the thoughts, while those who are naturally more accepting of their intrusive thoughts are less obsessional, have lower levels of depression, and are less anxious. Study II compared three groups (thought suppression, acceptance, and monitor-only groups) on the frequency and distress associated with experiencing personally relevant intrusive thoughts. Results revealed that those instructed to suppress their personal intrusive thoughts were unable to do so and experienced an increased level of distress after suppression, whereas those instructed to use an acceptance-based strategy experienced a decrease in discomfort level (but not thought frequency) after having used such a strategy. These data offer initial evidence that acceptance may be a useful alternative to the suppression of personally relevant intrusive thoughts.     

The role of objective versus perceived life threat in the psychological adjustment to cancer

Several studies in the oncology literature have used disease stage as a measure of life threat. According to the transactional model of stress (Lazarus and Folkman, ), however, the individual's perception of a threatening situation is more strongly related to distress than the objective event itself. Thus, the present study examined whether cancer patients’ perceived life threat (PLT) is more strongly associated with psychological adjustment than a more objective index of disease prognosis (i.e., cancer stage). In addition, based on cognitive processing theories, this study examined whether intrusive thoughts and avoidance, cognitive characteristics of posttraumatic stress disorder (PTSD), mediate the relationship between PLT and distress. Patients diagnosed with various types of cancer (N = 97) completed questionnaires assessing PLT, cancer-related intrusive thoughts and avoidance, distress, and quality of life. Consistent with theoretical predictions, regression analyses showed that PLT, but not disease stage, was significantly related to psychological distress and quality of life. In addition, intrusive thoughts and avoidance mediated the relationship between PLT and distress. Taken together, these findings suggest that cancer patients’ PLT is more strongly related to distress than is cancer stage and that this association is partly due to cognitive symptoms that are part of PTSD symptomatology. Thus, patients who appraise their illness as life threatening may benefit from cognitive interventions aimed at reducing distress associated with intrusive thoughts.     

Intrusive thoughts and auditory hallucinations: a comparative study of intrusions in psychosis

Several theories of auditory hallucinations implicate the involvement of intrusive thoughts and other theories suggest that the interpretation of voices determines the distress associated with them. This study tested the hypotheses that patients who experience auditory hallucinations will experience more intrusive thoughts and be more distressed by them and interpret them as more uncontrollable and unacceptable than the control groups. It also examines whether the interpretation of hallucinations is associated with the distress caused by them and whether there are differences in the way that patients respond to and interpret their thoughts and voices. A questionnaire examining the frequency of intrusive thoughts and the reactions to them was administered to a group of patients with a diagnosis of schizophrenia who experienced auditory hallucinations, a psychiatric control group and a non-patient control group. In addition, the patients in the first group completed a similar questionnaire in relation to their voices. Analyses of covariance showed that patients who experienced auditory hallucinations had more intrusive thoughts than the control groups and that they found their intrusive thoughts more distressing, uncontrollable and unacceptable than the control groups. Correlational analyses revealed that patients' interpretations of their voices were associated with the measures of distress in relation to them. Repeated measures analyses of covariance found no differences between thoughts and voices on the dimensions assessed. The theoretical and clinical implications of these findings are discussed.     

Abortion as stigma: cognitive and emotional implications of concealment.

This study examined the stigma of abortion and psychological implications of concealment among 442 women followed for 2 years from the day of their abortion. As predicted, women who felt stigmatized by abortion were more likely to feel a need to keep it a secret from family and friends. Secrecy was related positively to suppressing thoughts of the abortion and negatively to disclosing abortion-related emotions to others. Greater thought suppression was associated with experiencing more intrusive thoughts of the abortion. Both suppression and intrusive thoughts, in turn, were positively related to increases in psychological distress over time. Emotional disclosure moderated the association between intrusive thoughts and distress. Disclosure was associated with decreases in distress among women experiencing intrusive thoughts of their abortion, but was unrelated to distress among women not experiencing intrusive thoughts.     

Managing unwanted intrusive thoughts in obsessive-compulsive disorder: Relative effectiveness of suppression, focused distraction, and acceptance

Suppression is one of various mental control techniques that people may use to manage unwanted thoughts. Evidence suggests that it is at best unsustainable and at worst counterproductive. This leads to the question: If suppression is a futile way to respond to unwanted, intrusive thoughts, what is a more effective alternative? In the current study, we evaluated the relative effectiveness of suppression and two alternative mental control techniques—focused distraction and acceptance—on the frequency of intrusions and distress associated with them. Results support the claim that suppression is a counterproductive technique for dealing with unwanted, intrusive thoughts in OCD. However, the harmfulness of suppression was reflected primarily in the magnitude of distress and not in intrusion frequency. Focused distraction and acceptance were the more effective techniques for managing clinically significant intrusive thoughts. We discuss implications for the cognitive treatment for OCD.     

The effects of sexual assault-related intrusion suppression in the laboratory and natural environment

Individuals with a history of sexual victimization often experience enduring intrusive thoughts associated with their assault history. Research suggests that the characteristic ways in which sexually assaulted individuals respond to aversive internal experiences (i.e., thoughts, emotions, etc.) can influence the psychological distress associated with these intrusions. This study investigated the effects of suppressing sexual assault-related intrusions in a sample of 61 female college students with a history of adolescent or adult sexual assault and recent assault-related intrusions. Participants were randomly assigned to suppress or monitor intrusions during a laboratory task and for 48 h outside the laboratory. In contrast to study hypotheses, findings indicated that intrusion monitoring was associated with higher subjective distress than suppression both in the laboratory and in the natural environment. No differences were found for the frequency of intrusions between groups in the laboratory. However, modest evidence for a rebound effect in intrusion frequency was found outside the laboratory.     

Self-report may underestimate trauma intrusions

Research examining maladaptive responses to trauma routinely relies on spontaneous self-report to index intrusive thoughts, which assumes people accurately recognize and report their intrusive thoughts. However, “mind-wandering” research reveals people are not always meta-aware of their thought content: they often fail to notice shifts in their attention. In two experiments, we exposed subjects to trauma films, then instructed them to report intrusive thoughts during an unrelated reading task. Intermittently, we asked whether they were thinking about the trauma. As expected, subjects often spontaneously reported intrusive thoughts. However, they were also “caught” engaging in unreported trauma-oriented thoughts. The presence and frequency of intermittent probes did not influence self-caught intrusions. Both self-caught and probe-caught intrusions were related to an existing tendency toward intrusive cognition, film-related distress, and thought suppression attempts. Our data suggest people may lack meta-awareness of trauma-related thoughts, which has implications for theory, research and treatment relating to trauma-related psychopathology.     

Self-blame attributions in women with newly diagnosed breast cancer: a prospective study of psychological adjustment.

Associations between self-blame and anxiety and depression symptoms in a sample of 76 women with breast cancer were investigated. At diagnosis, behavioral self-blame was associated with increased distress; at 3 months postdiagnosis, characterological self-blame was positively associated with affective symptoms and behavioral self-blame approached significance (p = .07); and at 6 months, behavioral self-blame was related to increased distress. Prospective analyses revealed that characterological self-blame at diagnosis approached significance in predicting distress at 3 months (p = .055) and was significant in predicting distress at 6 months and at 1 year after diagnosis. These data indicate that behavioral self-blame is a correlate of concurrent affective symptoms, whereas characterological self-blame predicts increased distress over time. Implications for social-cognitive processes in adaptation to breast cancer are discussed.     

Personality and sex differences in emotional responsiveness to positive and negative cognitive stimuli

To investigate the influence of psychoticism (P) and neuroticism (N) on emotional responding, a re-analysis was carried out on subjective and physiological data collected while Ss (n = 50) repeatedly imagined anxious (intrusive) or depressive, and pleasant thoughts or images. High N was associated with a greater negative mood state subsequent to imagining the distressing cognitive stimuli, though there was no relation with physiological reactivity. However, high P scorers did evidence less overall cardiac reactivity and, to a lesser extent, fewer skin resistance responses than low P Ss. The results are discussed in light of the moderating influence that stimulus and response characteristics as well as gender differences can have on the interaction between personality traits and emotional responding.     

Social stimuli increase physiological reactivity but not defensive responses

Emotional reactions are crucial in survival because they provide approach and withdrawal behaviors. However, an unsolved question is whether the social content of the affective stimuli has a specific effect on emotional responses. We studied whether the social content of affective pictures influenced the defensive response and response mobilization. For this purpose, we recorded startle blink reflex (a defensive response) and skin conductance responses (a measure of unspecific physiological reactivity or arousal) in 73 participants while they viewed a series of 81 pictures of varying affective valence and social content. Our results revealed that defense response, as indicated by increases in the magnitude of the startle blink reflex, was mainly dependent on threatening or unpleasant cues, but was unrelated to the social content of the pictures. The social content, however, had an influence on pleasant stimuli, provoking an increase in resource mobilization, as reflected by changes in electrodermal activity. Hence, the social content of the affective stimuli may increase the physiological arousal elicited by pleasant stimuli, and it appears to be unrelated to the defense reactivity provoked by unpleasant stimuli.     

Exoneration reduces adult conflict's effects on preschoolers' cognitions, behavioral distress, and physiology

In this experiment, the authors investigated the influence of exoneration from blame on children's overt behavioral distress and physiological reactivity following the presentation of overheard adult conflict. The participants were 48 children (48-71 months of age) and their mothers. Through random assignment, the authors presented 16 children with statements that exonerated them from an overheard disagreement between two adults, did not address 16 during a similar disagreement, and presented 16 with a neutral discussion of difficulties. Exonerated children responded with less distress than did nonaddressed children, but did not differ from children presented the neutral discussion, except for overt behavioral distress. Nonaddressed children most often blamed themselves for the argument. Exonerating statements may protect children from attributional error and resultant physiological arousal during adult conflict.     

Young adult couples’ behavioral and physiological responses to the infant simulator: A preliminary illustration of coparenting

This exploratory application of the infant simulator with two couples is designed to illustrate individual reactivity and coparenting behaviors in young couples in serious relationships who do not yet have children. A 35-min protocol with standardized onsets and offsets of inconsolable baby cries was used to capture partner’s individual behavioral and physiological responses as well as the couple’s joint efforts to soothe the crying baby. Task feasibility was demonstrated by couples’ persistent and wide-ranging efforts to calm the baby including rocking, feeding, changing, talking to the baby, and singing. Within-person fluctuations in ongoing heart rate (HR) and electrodermal activity (EDA) through the protocol suggested evidence of heightened physiological reactivity during baby crying compared to silence. During bouts of crying, higher HR also was evidenced when participants took the lead in caregiving as contrasted with assisting or busying themselves in another task. Behavioral observations indicated that this task elicited examples of coparenting behaviors including cooperation, support, undermining, and negotiating the division of labor. These preliminary pilot data demonstrate the potential of infant simulator paradigms with couples who are not yet pregnant but envision being future parents, and set the stage for future research to identify how individual and couple characteristics might impact reactions to shared baby caregiving.     

Young Children’s Physiological Reactivity during Memory Recall: Associations with Posttraumatic Stress and Parent Physiological Synchrony

Autonomic reactivity is implicated in stress response and social engagement – both key components of posttraumatic stress disorder (PTSD) – but few studies have examined autonomic reactivity in pediatric samples, and no known studies have examined physiological synchrony among children with PTSD and caregivers. In a sample of 247 young children (94 girls, 153 boys), most (85%) of whom had exposure to trauma and 40% who met criteria for PTSD, we examined children’s patterns of respiratory sinus arrhythmia (RSA) at baseline and in response to a memory recall task, as well as correspondence between parents’ and children’s RSA. Children with PTSD demonstrated significantly higher reactivity than other groups during their recollection of a traumatic memory, but not during other memory tasks. Regarding synchrony, caregivers’ and children’s RSA were more significantly and positively correlated during the trauma recall task among children who had had exposure to a potentially traumatic event but did not meet PTSD criteria, suggesting physiological synchrony may be protective in contexts of trauma. Overall, findings demonstrate physiological reactivity differences among young children with PTSD. While more work is needed to understand the meaning of parent-child physiological synchrony, these data suggest that children’s psychopathology is associated with physiological synchrony processes among young children with exposure to trauma.     

Comparison of positive and negative intrusive thoughts and experimental investigation of the differential effects of mood.

The similarity between positive and negative intrusive thoughts is considered for both recently occurring, personally relevant intrusions and for the same intrusions occurring during an experimental task involving self-monitoring. The results indicate that positive and negative intrusions differ in most respects. There was evidence that increasing the frequency of negative thinking is associated with a deterioration of mood. In a subsequent experiment, induced happy and sad moods were shown to differentially affect frequency of intrusions in a fashion consistent with mood congruency effects previously found in experiments on the effect of mood on memory. The implications of these findings for disorders involving the experience of intrusive thoughts such as OCD and depression are discussed.     

Women's Cognitive,Affective, and Physiological Reactions to a Male Coworker's Sexist Behavior1

Empirical research has documented the attitudinal and behavioral consequences of sexual harassment, but has not examined the physiological consequences. In the present study, we monitored women's autonomic physiological activity while they performed a word‐association task with a male confederate who was either harassing, egalitarian, or submissive. Subsequently, we examined the women's cognitive, affective, and physiological reactions as they prepared and delivered a speech to the same confederate. Results indicate that harassment led to greater cardiovascular reactivity during the word‐association task and to greater cognitive, negative affective, and cardiovascular reactions during the subsequent speech compared with other conditions. Subgroups of harassed women who confronted their coworker, or who blamed themselves for his behavior, also exhibited greater cardiovascular reactivity during both tasks compared to women who did not use these coping responses. We integrate our laboratory results with those obtained in field settings.     

Biological and caregiver correlates of behavioral inhibition

The aim of this study was to explore the relationships among measures of behavioral inhibition, physiological reactivity, and caregiver attitudes. Measures comprised of heart rate; survey assessments of caregiver empathy with the child, appropriateness of caregiver developmental expectations of the child, and use of positive discipline techniques; and observational measures of behavioral inhibition were gathered in a laboratory setting on 72, 5–6‐year old children. It was found that heart rate and behavioral inhibition were positively correlated (0.595), whereas behavioral inhibition was negatively correlated with caregiver attitudes of empathy (?0.356), appropriate expectations (?0.366), and use of positive discipline techniques (?0.275). However, there was no correlation between heart rate and caregiver attitudes. These data suggest that physiological reactivity to novel stimuli and caregiver attitudes of empathy, appropriate expectations, and use of positive discipline techniques conjointly influence behavioral inhibition in early childhood. Further, these three caregiver variables accounted for significant variance in children who had high reactive physiological profiles associated with inhibited behavior patterns, but did not display such patterns.

Affective reactivity of language symptoms, startle responding, and inhibition in schizophrenia

The speech of some schizophrenia patients becomes markedly more disordered when negative affect is aroused. The authors tested associations between affective reactivity of speech and responsiveness and inhibition on an acoustic startle task in a sample of 27 outpatients. Patients whose language was reactive to negative affect showed significantly higher initial startle amplitudes than those whose language was not reactive. However, they also showed greater habituation to repeated startle stimuli over trials, even after differences in initial amplitudes were controlled statistically. These findings suggest that affective reactivity of speech is associated with higher initial startle responsiveness but also with greater habituation and, conversely, that patients who are relatively nonreactive to excitatory affective and sensory stimuli are also less reactive to inhibitory input.
