Social rank and affiliation in social anxiety disorder

The present study examined the interpersonal lives of individuals with social anxiety disorder (SAD). According to evolutionary and interpersonal theories, we construed the interpersonal world using the social rank and the affiliation psychological systems. Two studies assessed measures of social rank, affiliation, social anxiety and depression among a population of treatment-seeking individuals with SAD. In study 1, individuals with SAD without major depressive disorder (MDD; n=42) were compared to healthy controls (n=47). In study 2, individuals with SAD and MDD (n=45) were compared to individuals with other anxiety disorders and MDD (n=31). Results indicated that SAD was related to perceiving oneself as having low social rank, being inferior, and behaving submissively, as well as to low perceived intimacy and closeness among peer relations, friendships and romantic relations. SAD was distinctly associated with these perceptions above and beyond the symptomatic (study 1) and the syndrome-level (study 2) effects of depression. These findings were further supported by a path analysis of the SAD participants from both studies. Our findings highlight the need to address both social rank and affiliation issues in the assessment and treatment of SAD.     

Adult romantic relationships as contexts of human development: a multimethod comparison of same-sex couples with opposite-sex dating, engaged, and married dyads

This article presents a multimethod, multi-informant comparison of community samples of committed gay male (n=30) and lesbian (n=30) couples with both committed (n=50 young engaged and n=40 older married) and noncommitted (n=109 exclusively dating) heterosexual pairs. Specifically, in this study the quality of same- and opposite-sex relationships was examined at multiple levels of analysis via self-reports and partner reports, laboratory observations, and measures of physiological reactivity during dyadic interactions. Additionally, individuals in same-sex, engaged, and marital relationships were compared with one another on adult attachment security as assessed through the coherence of participants' narratives about their childhood experiences. Results indicated that individuals in committed same-sex relationships were generally not distinguishable from their committed heterosexual counterparts, with one exception--lesbians were especially effective at working together harmoniously in laboratory observations.     

Acculturation of Host Individuals: Immigrants and Personal Networks

There has been a vast amount of research on the changes experienced by immigrants, but little is known about the changes experienced by host individuals. This article focuses on the role of host individuals in the networks of relations between immigrant populations and the communities from the dominant culture, as well as the changes experienced by host individuals because of their continuous contact with immigrants. This research applied a network approach to the study of the acculturation of host individuals. Two independent studies were carried out: a systematic analysis of the personal networks of Argentinean (n = 67), Ecuadorian (n = 59), Italian (n = 37) and German (n = 37) residents in Seville and Cadiz (Spain) (Study 1); and an ethnographic study with human service workers for Latin American immigrants in Boston (USA) (Study 2). With two different strategies, the role of host individuals in personal networks of foreigners in the United States and Spain was analyzed. The results show that host individuals tend to have less centrality than compatriots, showing an overall secondary role in the personal networks of immigrants. The lowest average centrality was observed in recent and temporal migrants, whereas the highest corresponded to the individuals with more time of residence in Spain. The personal networks of human service providers in the United States vary in ethnic composition and in their structural properties, and therefore shape different types of integrative bridges for immigrants.     

Differences on the projective hand test among chronic pain patients reporting three different pain experiences

This study examined personality differences among individuals experiencing 3 different types of pain. The projective Hand Test was administered to 90 individuals who were seeking treatment at a pain clinic in an urban area of the southeast United States. These people were seeking treatment for either arthritis (n = 31), fibromyalgia (n = 29), or migraine headaches (n = 30). A 2 (gender) x 3 (pain group) x Age Group multivariate analysis of variance was conducted using the quantitative Hand Test scoring variables as dependent measures. Results indicated that individuals who were seeking treatment for migraine headaches had a higher production rate of responses involving exhibitionistic displays (EXH) than individuals in the other 2 groups. Individuals who were seeking treatment for fibromyalgia had a higher production rate of responses indicating fear and phobic concerns (FEAR) than individuals in the other 2 groups. Individuals who were seeking treatment for arthritis had a higher production rate of Active (ACT) responses than individuals in the other 2 groups. Possible causes and consequences of these effects are discussed.     

Emotional Stroop via Internet among individuals with eating disorders

The present study investigated whether Stroop interference in eating disordered individuals for food - and body-related words, as repeatedly found previously using standard emotional Stroop tasks, would also be demonstrated when using an Internet based emotional Stroop task. Participants were anorexic women (n= 13), bulimic women (n= 20), non-clinically eating disordered women nevertheless over-concerned about eating and body appearance (n= 27) and normal control women (n= 31). Bulimic individuals showed Stroop interference for body-related words whereas anorexic individuals showed Stroop interference for food-related words. The present results thus suggest that administration of the emotional Stroop task is possible via the Internet. Furthermore, it is possible that the time consuming response delivery, relative to previous studies, could lead to Stroop interference only for the most emotionally significant information, in turn, differentiating between the core concerns of anorexic and bulimic individuals.     

Low self-esteem in differentiating fearful and self-conscious forms of shyness.

Differences between fearfully and self-consciously shy individuals in self-esteem were investigated. Analysis indicated that fearfully (n = 45) compared to self-consciously (n = 40) shy individuals self-reported lower self-esteem. This result suggests that the role of low self-esteem may be different for each shyness subtype. A possible explanation was proffered.     

Characterizing the musical phenotype in individuals with Williams Syndrome.

Williams Syndrome (WS), a neurodevelopmental genetic disorder, is characterized by peaks and valleys in mental function: substantial impairments in cognitive domains such as reasoning, arithmetic ability, and spatial cognition, alongside relatively preserved skills in social domains, face processing, language, and music. We report the results of a comprehensive survey on musical behaviors and background administered to the largest sample of individuals with WS to date (n = 118, mean age = 20.4), and compare the results to those obtained from a control group of typically developing normal individuals (n = 118, mean age = 20.9) and two groups of individuals with other neurodevelopmental genetic disorders, Autism (n = 30, mean age = 18.2) and Down Syndrome (n = 40, mean age = 17.2). Individuals with WS were found to be rated higher in musical accomplishment, engagement, and interest than either of the comparison groups, and equivalent on most measures to the control group. Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music. In addition, the effects of music listening (whether positive or negative) tended to last longer in the WS group. A factor analysis extracted seven principal components that characterize the musical phenotype in our sample, and discriminant function analysis of those factors was able to successfully predict group membership for the majority of cases. We discuss the neurobiological implications of these findings.     

Veridical and false memory for scenic material in posttraumatic stress disorder

The question whether memory aberrations in posttraumatic stress disorder (PTSD) also manifest as an increased production of false memories is important for both theoretical and practical reasons, but is yet unsolved. Therefore, for the present study we investigated veridical and false recognition in PTSD with a new scenic variant of the Deese-Roediger-McDermott (DRM) paradigm, which was administered to traumatized individuals with PTSD (n=32), traumatized individuals without PTSD (n=30), and non-traumatized controls (n=30). The PTSD group neither produced higher rates of false memories nor expressed more confidence in errors, but did show inferior memory sensitivity. Whereas depressive symptoms did not correlate with veridical nor false recognition, state dissociation was positively associated with false memories.     

Perceptual style and behavioral pattern of individuals with functional gastrointestinal disorders.

The present research examined the perceptual style and coping pattern characterizing individuals with functional gastrointestinal disorders. A matched case-control design was adopted to compare differences among the target group of individuals with functional gastrointestinal disorders (n = 40), a pain control group of individuals with rheumatism (n = 40), and the community control group of healthy individuals (n = 40). Perceptual style was measured by both monitoring and blunting responses to hypothetical stressful situations, and coping pattern was measured by the use of coping strategies in real-life stressful events. Results revealed that participants with functional gastrointestinal disorders differed from their healthy and rheumatic counterparts in having higher monitoring and lower blunting scores and using action-oriented coping strategies regardless of the controllability of stressful situations.     

Learning style and personality type.

To investigate the relations between the Myers-Briggs Type Indicator and the Gregorc Style Delineator and to examine the construct validity of the Style Delineator, 41 undergraduate students preparing to be teachers were given both tests. Observed differences in learning styles by personality type partially support the construct validity of the Style Delineator. Judging individuals (n = 25) tended to perceive themselves as concrete sequential thinkers as opposed to perceptive individuals (n = 16) who thought of themselves as concrete random thinkers. Feeling types (n = 29) tended to prefer random modes of thinking.     

Thought suppression in spider-fearful and nonfearful individuals

The authors examined the suppression of spider-related thoughts in spider-fearful (n = 23) and nonfearful (n = 22) individuals. Participants were primed with vivid pictures of spiders and a story about spiders. Next, they were randomly assigned to 1 of 2 conditions: (a) suppression of thoughts associated with the previously presented spider-related stimuli or (b) free expression of any thoughts, including those related to the spider-related stimuli. All participants completed a subsequent free-expression exercise. Results indicated that spider-fearful individuals expressed thoughts about the spider-related stimuli for a longer length of time than did nonfearful individuals, particularly in the suppression condition. Participants in both groups demonstrated a rebound of thoughts associated with the spider-related stimuli following suppression. The authors propose that the priming of feared stimuli makes suppression of fear-related thoughts particularly difficult for fearful individuals, perhaps by activating a state of heightened arousal.     

Cognitive impairment in dementia: correlations with atrophy and cerebrovascular disease quantified by magnetic resonance imaging

This project assessed the contributions of atrophy and cerebrovascular disease (CVD) to cognitive impairment in dementia. Ten individuals with clinically diagnosed pure VaD were age-, sex-, and education-matched to individuals with AD. All participants underwent neuropsychological testing and MRI which were processed to generate quantitative indices of atrophy and CVD. A linear regression, including thalamic lesion and vCSF volumes, predicted cognitive status (R2 = .74; p < .0005). Three VaD subgroups were identified: thalamic lesion (n = 4), hippocampal infarcts (n = 3), and other (n = 3). In participants without thalamic lesion, vCSF predicted general cognition (R2 = .48), hippocampal atrophy predicted memory impairment (R2 = .33), and white matter lesions predicted executive dysfunction (R2 = .48). Both atrophy and CVD burden correlated highly with cognitive impairment and should be simultaneously assessed in studies of brain-behaviour relations in dementia.     

Depression and vulnerability as assessed by the Rorschach method

We examined clinically depressed (CD; n = 16), previously depressed (PD; n = 19) and never depressed (ND; n = 18) individuals on 13 theoretically selected Rorschach (Exner, 1993; Rorschach, 1942) variables and on the Beck Depression Inventory (BDI; Beck, Rush, Shaw, & Emery, 1979). The group assignment was made according to the criteria of Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). We tested 2 contradictory models for depressive vulnerability, Beck's (Clark & Beck, 1999) and Miranda and Persons's (1988; Persons & Miranda, 1992), in a planned comparison design with focused contrasts. The CDs significantly contrasted the combined group of NDs and the PDs in a pathological direction on 8 of the 13 Rorschach variables and on the BDI. However, the combined group of CDs and PDs also significantly contrasted the NDs in a pathological direction on 3 of these Rorschach variables and on the BDI. In addition, logistic regression analyses indicated that Rorschach indexes significantly improved the prediction of major depression above and beyond that achieved by the BDI. The findings show that the Rorschach method was able to identify (a) cognitive and aggressive disturbances that are present in individuals who are actively depressed but not in individuals who have been depressed in the past or never been depressed and (b) affective and coping disturbances that are present in depressed individuals and to some degree in PD individuals but not in individuals who have not experienced depression. We discuss the scanty evidence of psychological disturbances in PD individuals, as measured with the Rorschach, in relation to the mood-state dependent hypothesis of Miranda and Persons (1988; Persons & Miranda, 1992).     

Identifying Positive Dissimulation by Substance-Abusing Individuals on the Personality Assessment Inventory: A Cross-Validation Study

The accuracy of a classification equation (which combined scores on the Drug Problems, Alcohol Problems, and Positive Impression scales from the Personality Assessment Inventory [PAI], Morey, 1991), developed by Fals-Stewart (1996) to identify test-taking response sets among substance-abusing individuals, was evaluated. As in the Fals-Stewart (1996) study, three groups of participants completing the PAI were assessed: (a) substance-abusing patients administered the inventory under standard instructions (n = 25); (b) substance-abusing patients asked to respond defensively (n = 25) combined with a group of individuals suspected of abusing drugs, referred for art evaluation by the criminal justice system, who had reasons to conceal their drug use (n = 25); and (c) non-substance-abusing respondents administered the test under standard instructions (n = 25). Significant validity shrinkage in the classification equation was found when applied to the new sample; only 68% of participants were correctly classified into their respective groups, compared to 82% of participants correctly assigned in the Fals-Stewart (1996) investigation.     

Adult attachment style and partner choice: Correlational and experimental findings

Three studies were conducted to assess the role of attachment style in partner selection using both correlational and experimental methods. Study 1 (n = 83 couples) assessed correlations between partner ratings on attachment-style dimensions and the relations between own and partner attachment style and relationship satisfaction. In Study 2 (n = 226) and Study 3 (n = 146), participants who varied in terms of attachment style rated the desirability of potential partners who also differed in terms of attachment style. Results of all three studies generally suggested that individuals were most attracted to partners with similar attachment styles. For example, anxious individuals tended to be dating anxious partners in Study 1, and they preferred anxious partners over secure and avoidant partners in Studies 2 and 3 (combined data). Thus, not all individuals preferred secure partners. Second, unlike previous studies that looked primarily at partner correlations, there was no evidence of anxious/avoidant matching. In fact, anxious individuals seemed particularly averse to avoidant partners. Finally, ratings of parental caregiving styles (especially ratings of mothers) were associated with adult attachment dimensions and partner choices. For example, individuals who rated their mothers as more cold and ambivalent were less attracted to secure partners. Clinical and research implications are discussed.     

Cognitive inhibition and interference in dissociative identity disorder: the effects of anxiety on specific executive functions

Using an experimentally based, computer-presented task, this study assessed cognitive inhibition and interference in individuals from the dissociative identity disorder (DID; n=12), generalized anxiety disorder (GAD; n=12) and non-clinical (n=12) populations. Participants were assessed in a neutral and emotionally negative (anxiety provoking) context, manipulated by experimental instructions and word stimuli. The DID sample displayed effective cognitive inhibition in the neutral but not the anxious context. The GAD sample displayed the opposite findings. However, the interaction between group and context failed to reach significance. There was no indication of an attentional bias to non-schema specific negative words in any sample. Results are discussed in terms of the potential benefit of weakened cognitive inhibition during anxious arousal in dissociative individuals.     

The structure of feared social situations among individuals with a lifetime diagnosis of social anxiety disorder in two independent nationally representative mental health surveys

The present study employed both exploratory and confirmatory factor analytic approaches with nationally representative samples of individuals with a lifetime diagnosis of social anxiety disorder (n=1123; n=3091, respectively) using split-halves of the National Comorbidity Replication Survey (n=9282) and cross-validated with the Canadian Community Health Survey on Mental Health and Wellbeing (n=36,984). Strong support was found for a three-factor solution. This model was obtained from exploratory factor analysis and was further evaluated using two confirmatory factor analytic investigations in the two national samples. The three social situational domains reflected (1) Social Interaction Fears, (2) Observation Fears, and (3) Public Speaking Fears. Individuals with generalized social anxiety disorder (i.e., those who endorsed 7 or more of 13 feared social situations assessed in the survey) were significantly more likely to report Social Interaction Fears and Observation Fears compared to individuals with non-generalized social anxiety disorder (i.e., those who endorsed only 6 or fewer of 13 feared social situations). Individuals with generalized social anxiety were particularly characterized by combinations of Public Speaking Fears plus Social Interaction Fears and Observation Fears. The clinical and classification implications of our study for DSM-V are discussed.     

Communication and social skills in socially anxious and nonanxious individuals in the context of romantic relationships

This study examined differences between socially anxious and nonanxious individuals' ability to use effective communication skills and social skills in the context of romantic relationships. Socially anxious (n = 13) and nonanxious (n = 14) individuals and their romantic partners were videotaped while participating in 10-minute neutral, negative, and pleasant conversations. Regardless of the type of conversation in which they were involved, socially anxious individuals demonstrated impairment in 10 of the 11 social skill variables assessed. In negative conversations, socially anxious individuals displayed more "very negative" behaviors than nonanxious individuals, and across all conversations they displayed fewer "positive" behaviors than nonanxious individuals. Partners of socially anxious and nonanxious individuals did not differ in their communication quality. The results suggest that social anxiety is associated with deficits in relationship maintenance behavior and call for the completion of a larger study examining the interpersonal consequences of social anxiety.     

Facial expression recognition ability among women with borderline personality disorder: implications for emotion regulation?

This study examined recognition of facial expressions of emotion among women diagnosed with borderline personality disorder (BPD; n = 21), compared to a group of women with histories of childhood sexual abuse with no current or prior diagnosis of BPD (n = 21) and a group of women with no history of sexual abuse or BPD (n = 20). Facial recognition was assessed by a slide set developed by Ekman and Matsumoto (Japanese and Caucasian Facial Expressions of Emotion and Neutral Faces, 1992), expanded and improved from previous slide sets, and utilized a coding system that allowed for free responses rather than the more typical fixed-response format. Results indicated that borderline individuals were primarily accurate perceivers of others' emotions and showed a tendency toward heightened sensitivity on recognition of fear, specifically. Results are discussed in terms of emotional appraisal ability and emotion dysregulation among individuals with BPD.     

Change in cognitive functioning associated with apoE genotype in a community sample of older adults

The influence of a genetic risk factor, apolipoprotein E (apoE) epsilon4 variant, was assessed in older adults aged 70 to 94 on 3 occasions over 7 years. The results of latent growth curve analyses are reported for individuals genotyped for apoE at the 2nd measurement occasion (n = 601) and for a subsample of individuals without probable or definite dementia during the 1st or 2nd occasion (n = 434). ApoE-epsilon4 status was a significant predictor of level and change in memory performance and change in speed performance in the full sample, and of initial level and change in memory performance in the nondemented subsample. These results support previous findings that apoE-epsilon4 is associated with accelerated memory deterioration in individuals without clinical dementia.
