Mothers were instructed to provide information about a novel animal to their children (N=60) by studying in secrecy either disgusting or neutral attributes that were allegedly characteristic of this animal. First, mothers were instructed to do this in a nonverbal way; then they were also allowed to use verbal utterances. Results indicated that nonverbal communication of disgust by the mothers failed to produce any effects on offspring's subjective evaluations of the animal. However, verbal information transmission did have a differential impact on children's feelings of disgust and fear. That is, children to whom mothers had verbally communicated about a set of disgusting specimens not only displayed higher levels of disgust (Cohen's d=1.02) but also exhibited higher levels of fear (Cohen's d=.62) towards the novel animal as compared to children to whom mothers had verbally communicated about neutral specimens. The effect on fear was mainly due to the fact that children after the verbal neutral information exhibited a clear decline in fear, whereas children to whom mothers had provided verbal disgust information maintained a similar level of fear towards the animal. The implications of these results for the familial transmission of disgust and fear will be discussed. http://repub.eur.nl/res/pub/37530/ 2012-12-01T00:00:00Z The present study examined the psychometric properties of the Disgust Emotion Scale for Children (DES-C). Principal components analysis of the DES-C data revealed five factors reflecting disgust toward (a) rotting foods, (b) injection and blood, (c) odors, (d) mutilation and death, and (e) animals, which were largely in keeping with the intended subscales. The DES-C showed good reliability, excellent convergent validity (as established by correlations with an alternative self-report index of disgust), fairly good predictive validity (as assessed by correlations with measures of fear/anxiety and a behavioral index of disgust), and acceptable parent-child agreement (in particular with the mothers). Importantly, the DES-C proved to perform better on some psychometric indicators than an age-downward version of the Disgust Scale. These findings indicate that the DES-C should be regarded as the preferred scale for measuring disgust sensitivity and its role in the etiology and maintenance of anxiety problems in children. http://repub.eur.nl/res/pub/39989/ 2012-11-01T00:00:00Z The Behavioral Inhibition Questionnaire-Short Form (BIQ-SF) is a 14-item parent-rating scale for assessing an inhibited, anxiety-prone temperament in preschool children. This study examined the psychometric properties of the BIQ-SF scores in a multi-ethnic community population of Dutch boys and girls aged 2.5-6 years (total N = 2,343, from which various subsamples were derived). Results revealed that the factor structure of the BIQ-SF was as hypothesized: a model with six correlated factors representing children's inhibited behaviors in various social and non-social contexts provided a good fit for the data. The internal consistency of the BIQ-SF was generally satisfactory and scores on the scale were found to be fairly stable over a time period of up to 2 years. Parent-teacher agreement was acceptable, and relations between the BIQ-SF and observations of an inhibited temperament were moderate. Finally, BIQ-SF scores were positively associated with measures of anxiety and internalizing symptoms, whereas no significant links were found with externalizing symptoms. Altogether, these results provide support for the reliability and validity of the BIQ-SF as an economical method for assessing behavioral inhibition and anxiety proneness in young children. http://repub.eur.nl/res/pub/37968/ 2012-03-01T00:00:00Z Objective: During the past decades, cosmetic surgery has become increasingly popular. People with certain psychopathology disorders, for example, body dysmorphic disorder (BDD), are dissatisfied with their physical appearance, and a significant number try to receive cosmetic medical treatment for their complaints. It seems relatively easy for them to receive this type of surgery, despite the fact that it has no or even adverse effects on the symptoms. The present study aimed to investigate the psychological condition and especially the presence of psychopathological symptoms such as BDD in cosmetic surgery patients. Methods: Questionnaires about body image dissatisfaction, symptoms of BDD and psychopathology in general and satisfaction about surgery were sent to patients who had been treated in a large cosmetic surgery clinic. Results: Of the patients who replied, 86% were pleased with the outcome of the cosmetic procedure. Further, 21-59% of these former patients scored higher on questionnaires of body image dissatisfaction and psychopathological symptoms than a norm group from the general population. When differentiating the group on the basis of BDD symptomatology, it appeared that the high BDD symptomatic group displayed significantly worse outcome on all measurements. That is, high BDD symptomatic patients were more dissatisfied about the result of surgery, exhibited higher levels of psychopathology, and had lower self-esteem than the low symptomatic BDD patients. Conclusion: These findings clearly suggest that the evaluation of the psychological condition and motivation of the candidate patient might be a valuable addition to the standard procedure in cosmetic medical treatment settings. http://repub.eur.nl/res/pub/22996/ 2011-06-01T00:00:00Z This study explored the effects of positive information and imagery as ways of reducing a verbally installed fear in children. Seventy-two primary school children aged 9-13 years were first exposed to negative information to induce fear of a novel animal, and were then randomly assigned to three interventions: positive information, imagery, or a control condition. Outcome of various interventions was assessed by means of a standardized scale of fear beliefs and an index of confirmation bias (defined as the tendency to search for threat information in relation to the feared stimulus). Results indicated that both positive information and imagery were more effective in reducing fear than the control condition. Some evidence was also obtained showing that positive information was more effective than imagery, which suggests that this intervention represents the most optimal treatment approach when dealing with verbally acquired fears in children. http://repub.eur.nl/res/pub/26616/ 2011-06-01T00:00:00Z Previous eye movement studies of attentional bias in spider fear reported inconsistent results with respect to early attentional capture, suggesting that overt attentional capture only reliably occurs under specific circumstances. In addition, none of these studies explored covert attention. The present study examined attentional bias in spider phobia using a change detection paradigm that was expected to provide good conditions for documenting attentional capture. In contrast to our expectations, eye movement data showed that all participants' first fixations were fastest on general negative targets, whereas participants' first fixations on spider targets were slower in the spider fearful than in the nonfearful group. In addition, spider fearful participants made more nontarget fixations before fixating on a spider target than did nonfearful participants. Thus, we found that participants' overt attention was more quickly focused on general negative targets, whereas covert attentional processes enabled initial avoidance of fear-relevant (i.e. spider) stimuli. The present findings have important implications for research on attention and fear as they indicate that fearful individuals are not characterized by static attentional orienting toward threat but, under certain conditions, may avert attention from threat automatically. http://repub.eur.nl/res/pub/22754/ 2011-01-01T00:00:00Z This study explored the effects of positive information and imagery as ways of reducing a verbally installed fear in children. Seventy-two primary school children aged 9-13 years were first exposed to negative information to induce fear of a novel animal, and were then randomly assigned to three interventions: positive information, imagery, or a control condition. Outcome of various interventions was assessed by means of a standardized scale of fear beliefs and an index of confirmation bias (defined as the tendency to search for threat information in relation to the feared stimulus). Results indicated that both positive information and imagery were more effective in reducing fear than the control condition. Some evidence was also obtained showing that positive information was more effective than imagery, which suggests that this intervention represents the most optimal treatment approach when dealing with verbally acquired fears in children. http://repub.eur.nl/res/pub/19771/ 2010-04-01T00:00:00Z This study describes a first exploration of the construct of courage in youths. Children aged 8-13 years were invited to report on the most courageous action that they had ever performed during their life. In addition, the Courage Measure for Children (CM-C) was construed as an index of children's level of personal courage, and this scale was administered in two samples of school children (Ns being 168 and 159) along with a number of other questionnaires. Results indicated that children were familiar with the concept of courage as more than 70% reported to have carried out a courageous action during their life. In addition, self-reported courage as indexed by the CM-C was positively correlated with scores on a vignette measure of courage, parent ratings of children's courage, extraversion, openness/intellect, and a masculine sex role, whereas a negative correlation was observed with anxiety symptoms. The implications of these findings and potential directions for future research are briefly discussed. http://repub.eur.nl/res/pub/21375/ 2010-01-01T00:00:00Z Covariation bias refers to the phenomenon of overestimating the contingency between certain stimuli and negative outcomes, which is considered as a heuristic playing a role in the maintenance of certain types of psychopathology. In the present study, an attempt was made to investigate covariation bias within the context of eating pathology. In a sample of 61 female undergraduates, . a priori and . a posteriori contingencies were measured between pictures of obese and slim bodies, on the one hand, and fear- or disgust-relevant outcomes, on the other hand. Results indicated that participants in general displayed an . a priori and an . a posteriori covariation bias reflecting an overestimation of the link between obese bodies and disgust-relevant outcomes. However, this bias was not related to eating disorder symptomatology. Meanwhile, eating pathology was positively associated with . a priori covariation biases referring to the associations between obese bodies and fear-relevant outcomes, and between slim bodies and disgust-relevant outcomes. All in all, these findings suggest that covariation bias plays a role in eating pathology. http://repub.eur.nl/res/pub/16966/ 2009-08-01T00:00:00Z The present study investigated disclosure patterns among mental health consumers (N = 500) and examined the relationships among disclosure, perceived stigmatization, perceived social support, and self-esteem. Results suggest that selective disclosure optimizes social support and limits stigmatization. Perceived stigmatization has a detrimental impact on self-esteem, especially for those who are relatively open about their mental disorder. http://repub.eur.nl/res/pub/17582/ 2009-07-01T00:00:00Z Disgust is a basic emotion that is thought to play a role in the etiology of certain types of specific phobias, like animal phobias. Two experiments were conducted in which 9- to 14-year-old children were exposed to disgust-related, cleanliness-related, and threat-related information about unknown animals. It was investigated to what extent these types of information influenced children's fear beliefs, feelings of disgust, and avoidance behavior in relation to the animals. Most important, results suggested a bidirectional relationship between disgust and fear. That is, disgust-related information was found to promote fear beliefs, and conversely threat-related information enhanced feelings of disgust. Repercussions of these findings for the role of disgust in the development and maintenance of anxiety pathology are discussed. http://repub.eur.nl/res/pub/17580/ 2009-06-01T00:00:00Z This study explored correlations between risk factors and eating behavior problems in late adolescent, non-clinical females (N = 301). Participants completed questionnaires for assessing eating problems, the closely associated factors of Body Mass Index (BMI) and body dissatisfaction, and a number of other risk variables that are thought to be involved in psychopathology in general, namely insecure attachment, low self-esteem, and negative affect (i.e., social anxiety and depression). Results indicated that high levels of eating problems were associated with high levels of insecure attachment, social anxiety, and depression, and with low levels of self-esteem. Further, regression analyses suggested that depression and self-esteem had a unique, direct relationship with eating problems, whereas insecure attachment and social anxiety only seemed to have indirect relations. The links between these general risk variables and eating behavior problems were independent from the specific eating problem correlates of BMI and body dissatisfaction. http://repub.eur.nl/res/pub/18279/ 2009-04-01T00:00:00Z The "space odyssey" paradigm refers to an experimental method that can be used to manipulate interpretation bias in youths. In this study, the "space odyssey" paradigm was employed to induce either a negative or a positive interpretation bias in a sample of 120 non-clinical children aged 9-13 years. The results indicated that children's interpretation bias and avoidance tendencies scores were successfully manipulated during the experiment. That is, children in the negative training group showed an increase in negative interpretation bias and avoidance tendencies, whereas children in the positive training group exhibited a decrease in interpretation bias and avoidance tendencies, although it should be admitted that these effects in general were rather weak. Further, no support was found for the idea that high-anxious children were more affected by the experimental manipulation than low-anxious children. http://repub.eur.nl/res/pub/14951/ 2009-03-01T00:00:00Z The purpose of the present study was to evaluate negative automatic thoughts and anxiety control as predictors of change produced by cognitive-behavioral treatment of youths with anxiety disorders. Forty-five high-anxious children aged between 9 and 12 years who were selected from the primary school population, received a standardized CBT intervention that was provided in a group format. Before and after the intervention, children completed scales of negative automatic thoughts and perceived control over anxiety-related events as well as a questionnaire for measuring DSM-defined anxiety disorders symptoms, which was the outcome measure. Results indicated that CBT was effective in reducing children's anxiety symptoms. Most importantly, the reduction of anxiety disorders symptoms was significantly associated with a decrease in negative automatic thoughts and an increase of anxiety control, which provides support for the notion that these variables are candidate mediators of CBT in anxious youths. http://repub.eur.nl/res/pub/14953/ 2009-03-01T00:00:00Z This study examined relationships between behavioral inhibition, Big Five personality factors, and anxiety disorder symptoms in non-clinical children aged 9-12 years (N = 226), using children's self-report and parent-report data. Results indicated that behavioral inhibition is best characterized by low extraversion with a tinge of neuroticism. Further, behavioral inhibition was clearly associated with anxiety symptoms, even when controlling for the influence of Big Five personality factors (including neuroticism). These results indicate that although behavioral inhibition partly overlaps with basic personality factors, this temperament characteristic remains an important predictive variable of anxiety pathology in youths. http://repub.eur.nl/res/pub/18343/ 2009-03-01T00:00:00Z The present study made an attempt to induce fear-related reasoning biases by providing children with negative information about a novel stimulus. For this purpose, non-clinical children aged 9-12 years (N = 318) were shown a picture of an unknown animal for which they received either negative, ambiguous, positive, or no information. Then children completed a series of tests for measuring various types of reasoning biases (i.e., confirmation bias and covariation bias) in relation to this animal. Results indicated that children in the negative and, to a lesser extent, the ambiguous information groups displayed higher scores on tests of fear-related reasoning biases than children in the positive and no information groups. Altogether, these results support the idea that learning via negatively tinted information plays a role in the development of fear-related cognitive distortions in youths. http://repub.eur.nl/res/pub/17936/ 2009-01-01T00:00:00Z Psychopathology in youths is thought to originate from a dynamic interplay of a variety of protective and vulnerability factors. In this study, a large multi-ethnic sample of non-clinical adolescents (N = 376) completed questionnaires for measuring a wide range of person-related protective and vulnerability factors as well as psychopathology symptoms, in order to explore (a) the relations among various protective and vulnerability factors, and (b) the unique contributions of these protective and vulnerability factors to different types of psychological problems. Results indicated that the overlap among protective and vulnerability factors was quite modest. Further, it was found that factors clustered in theoretically meaningful components reflecting protection, vulnerability, and more specific aspects of coping and social support. Finally, data indicated that each type of psychopathology symptoms was associated with a typical set of protective and vulnerability factors. Although these results should be interpreted with caution because of the cross-sectional nature of the study, they may nevertheless guide future research exploring multifactorial models of psychopathology in youths. http://repub.eur.nl/res/pub/14587/ 2008-12-01T00:00:00Z In order to further explore the relationship between disgust sensitivity and eating disorder symptoms, 2 studies were carried out. In the first study, 352 higher education students (166 women, 186 men) completed a set of questionnaires measuring various aspects of disgust sensitivity and eating disorder symptoms. A correlational analysis revealed that there were few significant correlations between disgust scales and eating pathology scores. One exception was the relation between disgust sensitivity and external eating behavior, although this link only emerged in women. To investigate this relationship in more detail, Study 2 confronted women high (n = 29) and low (n = 30) on external eating behavior with a series of disgusting and neutral pictures. It was hypothesized that women who scored high on external eating would display shorter viewing times of disgusting pictures (i.e., show more avoidance behavior) than women scoring low on external eating. However, this hypothesis was not confirmed by the data. Altogether, the results of these studies suggest that there seems to be no convincing relationship between disgust sensitivity and eating disorder symptomatology, thereby casting doubts on the role of this individual difference factor in the development of eating pathology. http://repub.eur.nl/res/pub/15113/ 2008-12-01T00:00:00Z This study investigated the relation between the regulative trait of effortful control, and in particular attention control, and psychopathological symptoms in a sample of 207 non-clinical children aged 8-12 years. For this purpose, children completed self-report scales for measuring regulative traits and various types of psychopathological symptoms (i.e., anxiety, depression, and aggression) and were tested with a neuropsychological battery for measuring attention/effortful control capacity. Results indicated that self-report and performance-based measures of attention/effortful control were at best moderately correlated. Further, it was found that self-report indexes of attention/effortful control were clearly negatively related to psychopathological symptoms, which provides support for the notion that low regulation is associated with higher levels of psychopathology. Finally, the performance-based measure of attention/effortful control was not convincingly related to psychopathological symptoms. http://repub.eur.nl/res/pub/15117/ 2008-12-01T00:00:00Z This study provides a first test of an experimental method, the "space odyssey" paradigm, that was designed to manipulate interpretation bias in children. Seventy non-clinical children aged 8-12 years first completed a standardized anxiety questionnaire. Following this, they completed the space odyssey paradigm to induce either a negative or a positive interpretation bias. After this stage of interpretation training, children were presented with a series of ambiguous vignettes for which they had to rate perceived levels of threat as an index of interpretation bias. Results indicated that the space odyssey paradigm was successful in training interpretations: children in the negative training condition quickly learned to choose negative outcomes, while children in the positive training condition rapidly learned to select positive outcomes. Most importantly, children's subsequent threat perception scores for the ambiguous vignettes were affected by the manipulation. That is, children in the negative training condition perceived more threat than children in the positive training condition. Interestingly, the effects of training were most pronounced in high anxious children. Directions for future research with this paradigm are briefly discussed. http://repub.eur.nl/res/pub/15127/ 2008-10-01T00:00:00Z We examined to what extent children in The Netherlands are affected by the threat of terrorism. For this purpose, a sample of school children living in Rotterdam or adjacent satellites (N = 216) completed a fear survey that included a number of terrorism-related items, and were confronted with ambiguous vignettes to measure threat-related interpretation bias. The results demonstrated that although a number of terrorism-related items (i.e., bombing attacks, explosions in a bus or subway) listed high in a ranking of most intense childhood fears, very few children made terrorist-related interpretations of ambiguous situations. http://repub.eur.nl/res/pub/7237/ 2006-01-13T00:00:00Z Over the past decades many studies have examined the relationship between body esteem and self-esteem. However, researchers have paid limited attention to factors that moderate this relationship. The present field study investigates the moderating effect of age and gender on the relationship between body esteem and self-esteem. Furthermore, this study examines the influence of social comparison on body esteem. Adult men and women (N = 765) filled out a questionnaire. The positive relationship between body esteem and self-esteem was replicated. Age and gender moderated the relationship between body esteem and self-esteem. Social comparison orientation, social comparison direction and gender influenced body esteem. http://repub.eur.nl/res/pub/2891/ 1999-01-01T00:00:00Z The revised version of the Screen for Child Anxiety Related Emotional Disorders (SCARED-R) is a self-report questionnaire that measures symptoms of DSM-IV linked anxiety disorders in children. The present study examined the factor structure of the SCARED-R in a sample of 674 normal Dutch school children aged 8 to 13 years. Exploratory factor analysis (principal components with oblimin rotation) clearly pointed in the direction of a 1-factor solution, suggesting that when applied to samples of normal children, the SCARED-R is a unidimensional measure. Additional exploratory and confirmatory factor analyses carried out on parts of the SCARED-R provided some support for the presence of the following factors: panic disorder, generalized anxiety disorder, separation anxiety disorder, school phobia, social phobia and three types of specific phobias. Implications of these findings for the use of the SCARED-R are briefly discussed.
