Anxiety and bodily symptoms under the threat of missile attacks: The israeli scene

Abstract

The present research, conducted in Israel during the recent “Desert Storm” operation in the Gulf, sets out to assess the degree of anxiety and bodily symptoms of Israeli citizens, threatened by Scud missile attacks and undergoing a period of acute stress. Data were gathered via questionnaires distributed during the crisis period to over 500 respondents, most of them residing in Haifa, one of the high-risk areas for the missile attacks at the time. State anxiety was reported to be highly elevated during the crisis period, in comparison with norm group data collected during normal times. The most frequently reported bodily symptoms were changes in eating habits (loss of appetite or overeating), fatigue, and insomnia. Women reported more anxiety and bodily symptoms, on average, than men, as well as higher tension, fear and depression. The younger adults in the sample reported more anxiety and bodily symptoms, as well as tension, fear and depression, than their older counterparts. Lower levels of fear and depression were reported at the later stages of the crisis than at the earlier ones; most stress indicators evidenced lower levels with the passage of time. Finally, a strong positive relationship between anxiety and bodily symptoms was found, over and above the contribution of background variables and response tendencies. The possible explanations for the effects of background variables, as well as the strong relationship between anxiety and symptoms reported, are discussed.     

Fear of fear,trait anxiety and aerobic fitness in relation to state anxiety during adrenalin provocation

Abstract

Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety.     

Examination stress and changes in mood and health related behaviours

Abstract

The present exploratory study evaluated the effect of stress (an examination period) on changes in mood and health related behaviours. 83 medical students completed measures of mood and health related bchaviours at baseline and four weeks later either during their examinations period (the stress condition) or after a comparative control period (the control condition). All subjects also completed ratings of stress mediating variables: social support, perceived control and coping style at baseline. The results showed deterioration in mood in terms of increases in depression and anxiety and changes in health related behaviours in terms of increased numbers of subjects who identified thcmsehes as smokers, and dcmascs in alcohol consumption, exercise and food intake in subjects in the stress condition. The results also suggest that social support moderated the effects of the examination stress and was related to greater decreases in smoking, decrcases in alcohol craving and increases in eating behaviour. In addition, an avoidance coping style (problem avoidance, wishful thinking) was related to greater decreases in eating behaviour. 'Ihe nsults an discussed in the context of the stress/illness link and the role of behavioural change.     

Changes in mood caused by staged, moderate physical activity]

This experiment provides a test for the common sense knowledge that moderate physical exercise leads to mood improvement. Furthermore, it was tested whether light exercise intensifies negative feeling states or alleviates them. 30 female and 30 male students of psychology served as subjects (mean age 25.3 years, SD = 4.8). After being exposed to a mood induction procedure designed to elicit either a positive or negative feeling state, the subjects had to pedal a bicycle ergometer with 0, 50 or 75 Watt load. Cardiovascular variables and self-reports of mood states were assessed during a baseline period, after the mood induction, following the ergometer exercise, and after a follow-up period. The mood induction procedures were successful, but only for a short duration. Physiological activation was observed according to the ergometer loadings. Moderate physical exercise led to an increase of positive feeling states (Concentration) and a decrease of negative feeling states (Tiredness) in the follow-up period. Corresponding changes in tension related states could not be observed, probably due to the weakness of the mood induction procedure employed and the low level of energetic activation reached.     

Evaluating panic-specific factors in the relationship between suicide and panic disorder

Work during the past decade has suggested an association between panic disorder and suicide (i.e., suicidal ideation and suicide attempts) that cannot simply be accounted for by co-occurring depression symptoms. To clarify the linkage between panic disorder and suicide, the association between panic-specific clinical and cognitive variables and suicide indicators were evaluated in patients with panic disorder (N=146). Analyses predicting the presence of suicidal ideation (positive, negative) after covarying the effects of a current mood disorder diagnosis and depression symptoms indicated a number of significant predictors including: (1) overall anxiety symptoms; (2) level of anticipatory anxiety; (3) avoidance of bodily sensations; (4) attentional vigilance toward bodily perturbations; and (5) phrenophobia (i.e., fear of cognitive incapacitation). Anxiety-specific variables did not account for unique variance in predicting prior history of suicide attempts.     

Anxiety and heart rate under psychological stress: The effects of exercise-training

Abstract The effects of a 12-week exercise-training program on cognitive, somatic, and behavioral anxiety and on heart rate responses to evaluative stress were scrutinized in 89 subjects randomly assigned to an experimental (exercise) or a control group. The training program consisted of exercises that were aimed to the improvement of the general physical fitness (i.e., strength, flexibility, and endurance). Following the 12-week training period, exercising subjects showed improved motor skill capacity as well as higher VO(2) max. In an anxiety inciting test situation, that consisted of the video-taped delivery of a 5-min speech, a mental arithmetic and a fine motor task, exercising subjects showed more favourable responses than control subjects in three ways: (a) they exhibited lower behavioral anxiety during the anticipation phase of the three stressors, (b) they reported lower cognitive and somatic anxiety during the anxiety provoking situation, and (c) their heart rate recovered faster, in contrast to both their baseline heart rate and the control subjects' heart rate, from the stress episode. These results demonstrate that a fitness-oriented exercise program has anxiolytic properties. They also provide a primary evidence that overt behavioral anxiety, as opposed to the usually measured self-reported anxiety, may be affected by exercise.     

Can you feel the beat? Interoceptive awareness is an interactive function of anxiety- and depression-specific symptom dimensions

Delineating the differential effects of anxiety versus depression on patterns of information processing has proved challenging. The tripartite model of mood disorders (Clark & Watson, 1991) suggests that one way forward is to adopt a dimensional rather than categorical approach, making it possible to explore the main and interaction effects of depression- and anxiety-specific symptoms on a given cognitive-affective process. Here we examined how the interplay of anxiety-specific arousal and depression-specific anhedonia symptoms in the same individuals relate to interoceptive (bodily) awareness. 113 participants with varying levels of mood disorder symptoms completed a heartbeat perception task to assess interoceptive accuracy. Superior interoception was associated with anxiety-specific arousal symptoms, and this relationship held when controlling for depression-specific anhedonia symptoms and shared general distress symptoms. This main effect was qualified by an interaction between anhedonia and arousal. As anhedonia symptoms increased in severity, the relationship between arousal and interoceptive accuracy became less strong. These results further validate the tripartite framework, help clarify the mixed existing literature on interoception in mood disorders, and suggest that considering the unique and interactive effects of different symptom dimensions is a useful strategy to help identify the cognitive-affective profiles associated with anxiety and depression.     

A model clarifying the role of mediators in the variability of mood states over time in people who stutter

PurposeElevated negative mood states such as social anxiety and depressive mood have been found in adults who stutter. Research is needed to assist in the development of a model that clarifies how factors like self-efficacy and social support contribute to the variability of negative mood states over time.MethodParticipants included 200 adults who stutter. A longitudinal design was employed to assess change in mood states over a period of five months. Hierarchical directed regression (path analysis) was used to determine contributory relationships between change in mood states and self-efficacy, social support, socio-demographic and stuttering disorder variables. Participants completed a comprehensive assessment regimen, including validated measures of mood states, perceived control (self-efficacy) and social support.ResultsResults confirmed that self-efficacy performs a protective role in the change in mood states like anxiety and depressive mood. That is, self-efficacy cushioned the impact of negative mood states. Social support was only found to contribute a limited protective influence. Socio-demographic variables had little direct impact on mood states, while perceived severity of stuttering also failed to contribute directly to mood at any time point.ConclusionsMood was found to be influenced by factors that are arguably important for a person to cope and adjust adaptively to the adversity associated with fluency disorder. A model that explains how mood states are influenced over time is described. Implications of these results for managing adults who stutter with elevated negative mood states like social anxiety are discussed.Educational Objectives: The reader will be able to describe: (a) the method involved in hierarchical (directed) regression used in path analysis; (b) the variability of mood states over a period of five months; (c) the nature of the mediator relationship between factors like self-efficacy and social support and mood states like anxiety, and (d) the contribution to mood states of socio-demographic factors like age and education and stuttering disorder variables like stuttering frequency and perceived severity.     

Anxiety and the spelling and use in sentences of threat/neutral homophones

The disambiguation of threat/neutral homophones was investigated in high- and low-trait anxiety subjects who had been exposed to either a positive or a negative mood manipulation procedure. Subjects were required first to spell each auditorily presented word and second, to generate and speak a sentence using the word. Difference indices were calculated for the spelling and the sentence usage data, i.e. the number of threat minus neutral interpretations. Examination of these indices revealed that subjects exposed to the negative mood manipulation procedure produced relatively more threat than neutral interpretations (for both spelling and sentence usage) than did subjects exposed to the positive mood manipulation procedure. Multiple regression analyses revealed that both the trait anxiety and mood manipulation variables contributed significantly to the prediction of the difference index on the spelling task. In the analysis of the use of homophones in sentences, only the mood manipulation variable contributed significantly to the prediction of the difference index on the sentence usage task.     

Feeling states of people experiencing depression,anxiety, or comorbid depression and anxiety symptoms during a multi-day charity cycling ride: An ecological momentary assessment study

ObjectiveRegular exercise has substantial benefits for mental health. The way people feel during exercise impacts motivation. This study investigated whether experiencing depression, anxiety or comorbid depression and anxiety symptoms impacted feeling state responses throughout a charity cycling ride.DesignTo achieve this aim, we conducted an ecological momentary assessment study of feeling states (via Pleasant and Negative Affect Schedule items) across a multi-day cause-based cycling event.MethodMultivariate and univariate generalized linear mixed models was applied to test how affective and self-conscious emotional experiences changed across time and whether feeling state change differed between people experiencing depression, anxiety, or comorbid depression and anxiety symptoms.ResultsFor people experiencing depression symptoms, positive feelings decreased and negative feelings increased throughout the event. People experiencing anxiety symptoms had initially elevated negative feeling states that decreased across the event. For people experiencing comorbid depression and anxiety symptoms, changes in pride mirrored that of people experiencing only depression symptoms (decrease from initially high levels); whereas changes in guilt mirrored that of people experiencing only anxiety symptoms (initially high levels that decreased throughout event).ConclusionsThese findings demonstrate that depression and anxiety symptoms put people at risk for having negative affective and emotional experiences during exercise events and that these effects are further complicated when depression and anxiety symptoms co-occur. Exercise events and interventions must consider how to mitigate the potentially demotivating impacts that negative affective judgments can have on motivation for future exercise participation of people experiencing depression and/or anxiety symptoms.     

Type a behavior as a generally available strategy: Varying activation by tasks and instructions

Abstract

This study tested the hypothesis that the proportion of subjects resorting to Type A behavior (increased effort powered by arousal in response to a challenge) would be governed by the appropriateness of effort/arousal to the task. Sixty-nine male and female subjects classified as Type A or not-A responders by Structured Interview performed physical exercise, a vigilance task and a videogame with or without challenging instructions. For the (effort-salient) exercise, instructions produced a mean increase in arousal regardless of behavior pattern, while in the vigilance (low salience) task they produced no effect. Only in the videogame task did behavior pattern classification predict arousal in interaction with instructions. Effort, as measured by performance, showed a trend to increase with challenging instructions. Ratings by subjects of physical feelings paralleled these results, but positive, negative and emotional feelings did not show behavior pattern or instruction effects. The results support a view of Type A as a generally available response to which individuals show a differential activation rather than a character trait.     

The short-term influence of high and low intensity physical exercise on mood

Abstract

This study was designed to replicate and extend previous observations that the acute response to high intensity exercise is an increase in anxiety and other negative feelings. Forty female volunteers were allocated to two conditions—20 exercised at high level (100W) for 1.5 min, while 20 exercised at a low level (ZW). The purpose of the experiment was disguised. Mood was assessed before. during and immediately after exercise, and over a 1.5-min recovery period. Subjects were subsequently divided into highly and moderately fit groups on the basis of cardiac responses to a standard workload. It was found that tensiodanxiety increased immediately after high intensity exercise, declining over the recovery period. A similar pattern was found for mental fatigue. During exercise itself, anxiety diminished in the low but not the high intensity condition, No differences between fitness groups were observed in these patterns, although highly fit subjects reported greater mental vigour and exhilaration than moderately fit subjects following high intensity exercise. The mechanisms that may mediate these responses are discussed.     

Thought listing and endorsement measures of self-referential thinking in test anxiety

Abstract

The primary purpose of the present study was to examine cognitive reactions of high and low test-anxious subjects while performing a task of extreme difficulty. A sample of 44 subjects (28 females, 16 males) attempted a difficult analogies task and then reported their thoughts during the task. Subjects also completed the Sarason Test Anxiety Scale and several other self-report measures of their cognitive reactions to the task. Thought listings were classified according to their referent (self, task, or unrelated) and their valence (positive, negative, or neutral). Correlational analyses were then performed with the various measures and revealed an association between test anxiety and reports of negative thoughts involving the self. Test anxiety was not related significantly to the number of thoughts involving the task nor to actual performance on the task. However, test-anxious subjects did report more negative expectancies for their performance and greater cognitive interference during the task. Negative self-expectancies were also related to more negative self thoughts, fewer positive self thoughts, and fewer positive task-related thoughts. The results are interpreted as further evidence for both the role of negative self-related cognitions in the experience of test anxiety and the usefulness of unstructured measures in anxiety research.     

Time series analysis of obsessional behavior and mood during self-imposed delay and response prevention

Time series analysis of more than a year of daily self-report of three subjects showed that self-imposed delay and response prevention was effective in decreasing obsessions and compulsions. The subject-controlled treatment had a varied effect on mood—anxiety decreased in two subjects, but depression increased in one. (A similar worsening of mood after elimination of obsessional behavior was found in a previous case study.) Apparently, successful treatment of obsessional behavior will not necessarily lead to an improvement in mood. Concurrent mood symptoms need to be targeted separately; and, plans should be made to deal with mood symptoms that may occur once obsessional behavior is removed.     

A qualitative study exploring the experience of people with IBD and elevated symptoms of anxiety and low mood and the type of psychological help they would like

Background: People with inflammatory bowel disease (IBD) are at increased risk of developing anxiety and low mood. We sought to explore the experience of people with IBD and moderate–severe symptoms of anxiety/low mood to identify psychological processes which could be targeted in psychological interventions, as well as the kind of psychological support preferred.

Methods: Twenty-five participants with IBD and moderate–severe symptoms of anxiety/low mood were recruited for interview. Template analysis was utilised to analyse interview data. We explored the situations, cognitions and behaviour linked to symptoms of anxiety and low mood by people with IBD, as well as the kind of psychological help preferred.

Results: Two themes were identified within participants accounts of symptoms of anxiety; ‘under performance’ and ‘preventing an accident’. Two further themes were identified for symptoms of low mood; ‘lack of understanding’ and ‘stigma’. Expertise and understanding was the main theme identified for the type of psychological help desired.

Conclusion: The analysis highlights situations, cognitions and behaviour linked to anxiety and low mood by people with IBD and the type of psychological support desired. Our findings link to the knowledge and competencies set for psychological therapist working with long-term conditions.     

Effects of Bodily Contact on Reactions to Crowding1

The present study examined the effects of bodily contact in a crowded environment. Initially, the skin conductance levels (SCL) of 160 males and females were obtained during rest and while bursting a balloon. In a subsequent session, subjects in same-sex groups of four were seated for 30 minutes in either (a) a large room, (b) a small room subjected to unavoidable bodily contact, or (c) a small room which was partitioned to either reduce or prevent bodily contact while allowing visual access. Measures of mood, tolerance for frustration, cognitive task performance, and self reports of annoyance and somatic distress were then taken. Results showed that crowding is stressful and that bodily contact makes a significant contribution to the amount of stress experienced for both men and women. In general, crowded subjects forced to touch showed the greatest increases in SCL, felt most annoyed, were most bothered by spatial intrusion during crowding, and had the lowest tolerance for frustration following crowding. Sex differences in mood following crowding and in reaction to the noncrowded environment were observed and appeared to be mediated by differential social concerns.     

Postpartum maternal mood,feeding practices,and infant temperament in Barbados

Maternal mood, infant feeding practices, and infant temperament, using the Carey-R scales, were assessed in 226 healthy, well-nourished Barbadian mothers and their infants during the first 6 months of life. Maternal moods were assessed by self-report using the Zung depression and anxiety scales and a morale scale. Even after correcting for background variables, maternal depression and anxiety ratings and reports of despair at 6 months postpartum were significantly associated with infant temperament ratings at 6 months, using the original Carey-R scales, with factors derived from principal components analysis of the Carey items, and with summary difficulty scores. Maternal depressive symptoms were associated with decreased infant adaptability, reduced approach, negative mood and an increased sensory threshold. Infants of depressed and anxious mothers were more resistant to change and preferred constancy. These significant relationships were linear across the range of maternal mood scores and were not limited to diagnosed cases of depression or anxiety. In contrast, feeding practices were not significantly correlated with infant temperament, although infant difficulty on the temperament scales was associated with an increase in difficult feeding behaviors and with fathers’ involvement in the feeding of their infants. We conclude that interventions focused on improving maternal mood in the postpartum period are likely to impact positively upon maternal perceptions of their infants, with implications for improving child behavioral development and health in this underserved population.     

Influences of habitual and situational bodily symptom focusing on stress responses

Evidence suggests that focusing on bodily symptoms increases perception of internal states. The interaction between situational (experimentally induced) symptom focusing and a disposition to focus on one's bodily symptoms is unclear. We assumed that situational symptom focusing increases perception of stress symptoms only in persons that usually do not focus on their bodily symptoms. Forty participants were divided into two groups (N=20) according to their disposition towards bodily symptom focusing (habitual symptom focusing, HSF+ and HSF?). Ten participants per group were instructed to focus on their neck muscle tension (situational symptom focusing, SSF+), while the others received a control instruction (SSF?). All participants underwent anticipation of a public speech, representing an emotional and mental stressor. There was a significant HSF×SSF interaction in reports on muscle tension and palpitation under stress. While HSF? participants reported more stress symptoms in the SSF+ condition, HSF+ participants reported less symptoms. However, no interaction was found in physiological measures including neck electromyogram, skin conductance reactions, heart rate and blood pressure. Our results indicate either that symptom perception is adjusted by symptom focusing, or that the instruction to use a habitual coping strategy reduces stress symptoms.     

Effects of gender role self-discrepancies and self-perceived attractiveness on social anxiety for women across social situations

Background and objectives: Psychosocial factors, such as gender role norms, may impact how social anxiety disorder (SAD) is experienced and expressed in different social contexts for women. However to date, these factors have not been examined via experimental methodology. Design: This was a cross-sectional, quasi-experimental controlled study. Methods: The current study included 48 highly socially anxious (HSA) women (70.9% meeting criteria for SAD) and examined the relationships among psychosocial factors (i.e. gender role self-discrepancies and self-perceived physical attractiveness), self-perceived social performance, and state anxiety, across two in vivo social tasks (i.e. conversation and opinion speech). Results: On average, participants reported belief that they ought to be less feminine for the speech task and more masculine for both the conversation and speech tasks. Also, for the conversation task, only lower self-rated attractiveness predicted poorer self-perceived performance and greater post-task state anxiety, above gender role self-discrepancies and confederate gender. For the speech task, only greater self-discrepancy in prototypical masculine traits predicted poorer performance ratings, and it was related to greater state anxiety in anticipation of the task. Conclusion: For HSA women, psychosocial factors may play different roles in social anxiety across social contexts.     

Self-awareness and emotional intensity

Abstract

Influences of mood on qualitative aspects of cognitive processing are examined within a semantic priming paradigm. The priming effect reflects the reduction of latency for a lexical decision task when a target word is presented in combination with an associatively related prime word. The effect was higher for subjects in whom positive affect had been induced than for a control group, if prime and target were high-associatively related. There was no effect of mood on priming for low-associatively related prime-target pairs. The results are interpreted in terms of a general facilitating influence of mood on spreading activation independent of the affective quality of the processed material.
