Interpretation of bodily symptoms in hypochondriasis.

Although it has been suggested that hypochondriasis is caused by the misinterpretation of innocuous bodily sensations, support for this hypothesis rests largely upon uncontrolled self-report. We investigated the interpretation of ambiguous bodily sensations in three experiments using separate samples of non-clinical subjects differing in level of hypochondriacal concern. Results confirmed that subjects with high hypochondriacal concern endorse more thoughts about illness interpretations of bodily sensations, but reported thought content resembled 'catastrophic' rather than the 'non-emergency' thoughts suggested by Warwick and Salkovskis (Hypochondriasis. Behavior Research and Therapy, 28, 105-117, 1990). Presence of an interpretive bias was further supported in a study of recognition bias for disambiguated versions of ambiguously threatening sentences, although this applied as much to social as to illness threats. A final experiment failed to support the hypothesis of an automatic inference bias, but did show that subjects with high hypochondriacal concern were quicker to correctly identify previously exposed illness words. Thus, reported thoughts are consistent with catastrophic interpretations of common bodily sensations, but interpretive bias may not be limited to illness threat. However, high hypochondriacal subjects do show a more specific enhanced perceptual sensitivity to illness cues, which may play a role in maintaining their concern with bodily symptoms.     

If you suffer from a headache, then you have a brain tumour: domain-specific reasoning 'bias' and hypochondriasis

We explored whether hypochondriacal patients selectively search for threat-confirming information when asked to judge the validity of conditional rules in the context of general and health threats. We also explored several factors that may underly participants' information selection (e.g., believability of the rule). Hypochondriacal patients (n = 20) and healthy controls (n = 20) were presented with modified Wason Selection Tasks (WSTs). The WSTs contained safety rules and danger rules. In the context of general threat, both groups of participants adopted a verificationistic strategy in the case of danger rules and a Popperian strategy in the case of safety rules. Importantly, only hypochondriacal persons showed a similar threat-confirming reasoning pattern in the context of health threat. The latter finding contrasts with the earlier study of de Jong et al. (1998) [de Jong, P. J., Haenen, M.-A., Schmidt, A., & Mayer, B. (1998a). Hypochondriasis: the role of fear-confirming reasoning. Behaviour Research and Therapy, 36, 65-74; de Jong, P. J., Mayer, B., van der Hijden, B., B?gels, S., & van den Hout, M. (1998b). Better safe than sorry: reasoning with conditionals in the context of threat. Submitted for publication.] in which both hypochondriacs and healthy controls showed a threat-confirming strategy in the domain of health threat. The WSTs in that study however, contained a (unintended) worry manipulation ("after hearing this, you get worried"), which might have induced a reasoning strategy in controls that is normally restricted to hypochondriacs. Taken together, the present results sustain the idea that the perception of threat activates a better safe than sorry strategy. In the case of phobic threats, such a reasoning strategy immunizes against refutation of phobic convictions.     

Salkovskis on obsessional-compulsive neurosis: a critique

Salkovskis (Behav. Res. Ther. 23, 571–583. 1985) offers of cognitive-behavioural analysis of obsessional-compulsive disorder and the treatment implications of the analysis are discussed by Salkovskis (1985) and Salkovskis and Warwick (Behav. Psychother. 13, 243–255, 1985). A number of criticisms and objections to this work are set out.     

The effects of endowment on the demand for probabilistic information

Research shows that individuals are ambiguity averse: they choose unambiguous over equivalent ambiguous prospects and price them higher (either as buyers or sellers). Moreover, it is often assumed that ambiguity averse individuals are willing to pay an ambiguity premium for information that reduces ambiguity [Camerer, C. F., & Weber, M. (1992). Recent developments in modeling preferences: Uncertainty and ambiguity. Journal of Risk and Uncertainty, 5(4), 325–370]. However, when people are asked to exchange an ambiguous alternative in their possession for an equivalent unambiguous one, they prefer to retain the former [Roca, M., Hogarth, R. M., & Maule, A. J. (2006). Ambiguity seeking as a result of the status quo bias. Journal of Risk and Uncertainty, 32(3), 175–194]. We present three experiments investigating the economic effects of endowment on attitudes towards ambiguity and the ambiguity premium. The experiments, based on a [Becker, G., DeGroot, M., & Marschak, J. (1964). Measuring utility by a single-response sequential method. Science, 9, 3] procedure, show that the value attributed to ambiguity reducing information is substantially affected by the status quo of the individual.     

Forming implicit and explicit attitudes toward individuals: social group association cues

The authors explored how social group cues (e.g., obesity, physical attractiveness) strongly associated with valence affect the formation of attitudes toward individuals. Although explicit attitude formation has been examined in much past research (e.g., S. T. Fiske & S. L. Neuberg, 1990), in the current work, the authors considered how implicit as well as explicit attitudes toward individuals are influenced by these cues. On the basis of a systems of evaluation perspective (e.g., R. J. Rydell & A. R. McConnell, 2006; R. J. Rydell, A. R. McConnell, D. M. Mackie, & L. M. Strain, 2006), the authors anticipated and found that social group cues had a strong impact on implicit attitude formation in all cases and on explicit attitude formation when behavioral information about the target was ambiguous. These findings obtained for cues related to obesity (Experiments 1 and 4) and physical attractiveness (Experiment 2). In Experiment 3, parallel findings were observed for race, and participants holding greater implicit racial prejudice against African Americans formed more negative implicit attitudes toward a novel African American target person than did participants with less implicit racial prejudice. Implications for research on attitudes, impression formation, and stigma are discussed.     

Anxiety sensitivity and panic symptomatology: the mediator role of hypochondriacal concerns

The present study tests the mediating role of hypochondriasis to explain the relation between anxiety sensitivity and panic symptomatology. Fifty-seven outpatients with clinically significant levels of panic symptomatology were selected to participate in the study. Measures of anxiety sensitivity, hypochondriasis, and panic symptomatology were obtained from standardized, self-administered questionnaires: the Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), the Whiteley Index of Hypochondriasis (WI; Pilowsky, 1967), and the Panic-Agoraphobic Spectrum Self-Report (PAS-SR; Cassano et al., 1997; Shear et al., 2001). Regression analyses were performed to test for the mediation models. The results show that the effect of anxiety sensitivity on panic symptomatology is not significant when controlling the hypochondriacal concerns, whereas the latter predicted panic symptoms. This result holds for the overall ASI as well as for the Physical Concerns and the Mental Incapacitation Concerns dimensions of the ASI scale. No evidence of a direct relation between the Social Concerns dimension and panic symptoms was found. The findings suggest that hypochondriacal concerns might represent the mechanism through which anxiety sensitivity is able to influence panic symptoms.     

Health-related stress, affect, and depressive symptoms experienced by caregiving mothers of adults with a developmental disability

The interrelationships among health-related stress, positive and negative affect, and depressive symptoms patterned in the dynamic model of affect (J. Reich, A. Zautra, & M. Davis, 2003) were examined using data from 932 women having an adult child with a developmental disability. Results indicate that women experience a moderate inverse correlation between positive and negative affect under conditions of low levels of health-related stress, whereas at high levels of stress, positive and negative affect become more strongly inversely correlated. Under high-stress conditions, both negative affect and positive affect have a stronger relationship to depressive symptoms than they do under low-stress conditions.     

Assessing obsessive compulsive symptoms and cognitions on the internet: evidence for the comparability of paper and Internet administration

Administration of psychological questionnaires via the Internet has gained popularity in recent years and touts many advantages. However, before questionnaires that were originally developed as paper-and-pencil measures can be confidently administered over the Internet, it is necessary to document the equivalence of the paper and computer-generated versions [American Psychological Association. (1986). Guidelines for computer-based tests and interpretations. Washington, DC: American Psychological Association; Cohen, R.J., Swerdlik, M.E., & Smith, D.K. (1992). Psychological testing and assessment (2nd ed.). Mountain View, CA: Mayfield Publishing; Cronbach, L.J. (1990). Essentials in psychological testing (5th ed.). New York: Harper Collins; Meier, S. (1994). The chronic crisis in psychological measurement and assessment: A historical survey. San Diego: Academic Press; Schulenberg, S.E., & Yutrzenka, B.A. (2001). Equivalence of computerized and conventional versions of the Beck Depression Inventory- II (BDI-II). Current Psychology: Developmental, Learning, Personality, Social, 20, 216-230]. The current study tested this equivalence for the Obsessive Compulsive Inventory [Foa, E.B., Kozak, M.J., Salkovskis, P.M, Coles, M.E., & Amir, N. (1998). The validation of a new obsessive compulsive disorder scale: The obsessive-compulsive inventory. Psychological Assessment, 10(3), 206-214] and the Obsessive Beliefs Questionnaire-44 [Obsessive Compulsive Cognitions Working Group. (2005). Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory-Part 2: Factor analyses and testing of a brief version. Behaviour Research and Therapy, 43, 1527-1543] in an unselected student sample. Study results support the equivalence of these measures of obsessive compulsive disorder (OCD) symptoms and beliefs independent of administration method (paper versus secure project website). These findings create new opportunities for conducting OCD-related research online.     

The feature-positive effect and hypochondriacal concerns

There is evidence to suggest that people have more problems with processing information that is absent (negative information) than with present (positive) information. This bias of overweighing positive and underweighing negative information has been termed the "feature-positive effect" (FPE). Typically, hypochondriasis is characterized by excessive focusing on bodily complaints (cf. positive information), and at the same time discarding negative medical test results (cf. negative information). It was explored whether the FPE is involved in this pattern. Fifty-three undergraduates completed a measure of hypochondriacal concerns and a general, domain-free test of the FPE. As expected, a positive correlation between the FPE and hypochondriacal concerns was observed. Implications for cognitive-behavioural theory are discussed.     

Semantic ambiguity and the process of generating meaning from print

An ambiguity disadvantage (slower responses for ambiguous words, e.g., bank, than for unambiguous words) has been reported in semantic tasks (L. R. Gottlob, S. D. Goldinger, G. O. Stone, & G. C. Van Orden, 1999; Y. Hino, S. J. Lupker, & P. M. Pexman, 2002; C. D. Piercey & S. Joordens, 2000) and has been attributed to the meaning activation process. The authors tested an alternative explanation; The ambiguity disadvantage arises from the decision-making process in semantic tasks. The authors examined effects of ambiguity on unrelated trials in a relatedness decision task, because these trials are free from response competition created by ambiguous words on related trials. Results showed no ambiguity effect on unrelated trials (Experiments 2, 3c, and 5c) and an ambiguity disadvantage on related trials (Experiments 3a, 3b, 5a, and 5b).     

Suppressing irrelevant information: knowledge activation or inhibition?

In 3 experiments, the authors examined the role of knowledge activation in the suppression of contextually irrelevant meanings for ambiguous homographs. In Experiments 1 and 2, participants with greater baseball knowledge, regardless of reading skill, more quickly suppressed the irrelevant meaning of ambiguous words in baseball-related, but not general-topic, sentences. Experiment 3 demonstrated that participants with greater general knowledge, regardless of reading skill, more quickly suppressed the irrelevant meaning of the ambiguous words in general-topic sentences. As predicted by D. S. McNamara's (1997) knowledge-based account of suppression, ambiguity effects are influenced by greater activation of knowledge related to the intended meaning of the homograph. These results challenge inhibition (e.g. M. A. Gernsbacher, K. R. Varner. & M. Faust, 1990) as the sole mechanism responsible for the suppression of irrelevant information.     

Learning and attention in multidimensional identification and categorization: separating low-level perceptual processes and high-level decisional processes

Four observers completed identification and categorization tasks. Learning and attention processes were examined by applying general recognition theory (F. G. Ashby & J. T. Townsend, 1986), which separates perceptual, decisional, and attentional processes. Learning led to decision regions that became more nearly optimal. Learning had little effect on perceptual processes in identification and decisional integration categorization tasks but affected perceptual processes in decisional selective attention categorization tasks, leading to perceptual selective attention. These findings suggest that (a) identification and categorization invoke decision strategies that are localized in the striatum (F. G. Ashby, E. M. Waldron, W. W. Lee, & A. Berkman, 2001) and (b) perceptual and decisional attention systems exist and are mediated by distinct brain structures (M. I. Posner & S. E. Petersen, 1990).

A test of competing models of the relationships among perceptions of organizational politics, perceived organizational support, and individual outcomes

The authors aimed to distinguish between perceptions of organizational politics (POPs) and perceived organizational support (POS). Previous research has shown that these two constructs are related, and whereas some researchers have suggested that POS mediates the relationships between POPs and outcomes (e.g., M. C. Andrews & K. M. Kacmar, 2001; R. Cropanzano, J. C. Howes, A. A. Grandey, & P. Toth, 1997), others have claimed that POPs mediate the relationships between POS and outcomes (e.g., G. R. Ferris, G. S. Russ, & P. M. Fandt, 1989). The authors investigated these competing models in an organizational sample of 418 employees from a water-management-district office. Results showed that POPs and POS were related to each other and to 5 outcomes: (a) job satisfaction, (b) pay satisfaction, (c) job strains, (d) role conflicts, and (e) turnover intentions. Results also indicated that POS fully mediated 3 of the 5 relationships between POPs and outcomes and partially mediated the other 2.     

Psychometric Measures of Boredom: A Review of the Literature

This research presents a review of the psychometric measures on boredom that have been developed over the past 25 years. Specifically, the author examined the Boredom Proneness Scale (BPS; R. Farmer & N. D. Sundberg, 1986), the job boredom scales by E. A. Grubb (1975) and T. W. Lee (1986), a boredom coping measure (J. A. Hamilton, R. J. Haier, & M. S. Buchsbaum, 1984). 2 scales that assess leisure and free-time boredom (S. E. Iso-Ahola & E. Weissinger, 1990; M. G. Ragheb & S. P. Merydith, 2001), the Sexual Boredom Scale (SBS; J. D. Watt & J. E. Ewing, 1996), and the Boredom Susceptibility (BS) subscale of the Sensation Seeking Scale (M. Zuckerman, 1979a). Particular attention is devoted to discussing the literature regarding the psychometric properties of the BPS because it is the only full-scale measure on the construct of boredom.     

The Obsessive-Compulsive Inventory: development and validation of a short version

This article reports on the development of a revised version of the Obsessive-Compulsive Inventory (OCI; E. B. Foa, M. J. Kozak, P. Salkovskis, M. E. Coles, & N. Amir, 1998), a psychometrically sound, theoretically driven, self-report measure. The revised OCI (OCI-R) improves on the parent version in 3 ways: It eliminates the redundant frequency scale, simplifies the scoring of the subscales, and reduces overlap across subscales. The reliability and validity of the OCI-R were examined in 215 patients with obsessive-compulsive disorder (OCD), 243 patients with other anxiety disorders, and 677 nonanxious individuals. The OCI-R, which contains 18 items and 6 subscales, has retained excellent psychometric properties. The OCI-R and its subscales differentiated well between individuals with and without OCD. Receiver operating characteristic (ROC) analyses demonstrated the usefulness of the OCI-R as a diagnostic tool for screening patients with OCD, utilizing empirically derived cutscores.     

Child care under pressure: the quality of Dutch centers in 1995 and in 2001

In 2001, the authors assessed the quality of care provided to children in 51 care groups from 39 child-care centers in The Netherlands using the Infant/Toddler Environment Rating Scale (T. Harms, D. Cryer, & R. M. Clifford, 1990) and compared the results with the quality of child care assessed in 1995 (M. H. van IJzendoorn, L. W. C. Tavecchio, G. J. Stams, M. J. E. Verhoeven, & E. J. Reiling, 1998). The overall quality and scale scores for language and learning activities were significantly lower in 2001 than in 1995. Child-care centers founded within the past 6 years (all nonsubsidized centers) scored considerably lower than did older, mostly subsidized, centers. The results are discussed from the perspective of changes in the socioeconomic and political context of child care.     

Cognitive avoidance,positive affect,and gender as predictors of the processing of aversive information

The study investigated the influence of cognitive avoidance, positive affect, and gender on the evaluation of and memory for threat-related information varying in degrees of aversiveness and ambiguity. Stimulus material consisted of threatening, nonthreatening, and ambiguous pictures. First, valence ratings of the stimuli were collected. This phase was followed by a first memory test. A second memory test was administered three days later. Memory for aversive information was influenced by cognitive avoidance, positive affect, and gender. Avoiders exhibited a comparatively good memory for aversive information in the first (immediate) test and a very poor memory in the delayed testing. A similar pattern was obtained for individuals high in positive affect. Compared to men, women gave more negative ratings to aversive and ambiguous pictures and had a better memory for ambiguous information in the immediate test. Results are discussed within the framework of the repressive discontinuity hypothesis proposed by Hock and Krohne [Hock, M., Krohne, H. W. (2004). Coping with threat and memory for ambiguous information: Testing the repressive discontinuity hypothesis. Emotion, 4, 65–86].

Farmer & N. D. Sundberg, 1986), the job boredom scales by E. A. Grubb (1975) and T. W. Lee (1986), a boredom coping measure (J. A. Hamilton, R. J. Haier, & M. S.

Ewing, 1996), and the Boredom Susceptibility (BS) subscale of the Sensation Seeking Scale (M. Zuckerman, 1979a). Particular attention is devoted to discussing the literature regarding the psychometric properties of the BPS because it is the only full-scale measure on the construct of boredom.     

Evaluating a sex-related ability: Comparison with same-, opposite-, and combined-sex norms

A study was conducted to replicate and extend Zanna, Goethals, and Hill's (Zanna, M. P., Goethals, G. R., & Hill, J. F. Journal of Experimental Social Psychology, 1975, 11, 86–93) experiment investigating social comparison choices for evaluating a sex-related ability. In a 2 × 3 design male and female undergraduates received ambiguous feedback about their performance on a test. The test was described as one in which either males typically excel or females typically excel, or no sex differences for performance were mentioned. Subjects were then given the opportunity to select normative comparison information in order to evaluate their performance. Information about same-sex, opposite-sex, and combined (male and female) norms was available. The results showed that interest in same-sex and combined information was high on both first and second choices. Opposite-sex comparisons were of low priority. Same-sex comparisons were of high priority even when sex differences were not made salient. Males and females differed to some extent in their comparison choices. The results suggest that while persons prefer to compare with similar (same-sex) others, they are also interested in making broader kinds of comparisons (with combined-sex norms). The results are discussed in terms of Wilson's (Wilson, S. R. Sociometry, 1973, 36, 600–607) two-process analysis of ability comparison and Goethals and Darley's (Goethals, G., & Darley, J. In J. M. Suls & R. L. Miller (Eds.), Social comparison processes; Theoretical and empirical perspectives. Washington, D. C.: Hemisphere/Halsted/Wiley, 1977) related attribute hypothesis.
