Perfectionism, perceived weight status, and self-esteem interact to predict bulimic symptoms: A model of bulimic symptom development.

An interactive model of perfectionism, perceived weight status, and self-esteem was tested on 342 female undergraduates to predict bulimic symptoms. Using a longitudinal design, the authors tested the model on data collected at 2 points: the spring of participants' senior year of high school and during participants' first year of college. The authors hypothesized and found that self-esteem moderates the interaction between perfectionism and perceived weight status in predicting bulimic symptoms. Women who are high in perfectionism and who consider themselves overweight exhibit bulimic symptoms only if they have low self-esteem (i.e., if they doubt they can attain their high body standards). High self-esteem women with the same diathesis-stress conditions are less likely to exhibit bulimic symptoms. These findings clarify the role of perfectionism in bulimic symptomatology.

Perfectionism and bulimic symptoms in African American college women: Dimensions of perfectionism and their interactions with perceived weight status.

This study had 2 primary aims: (a) to examine the unique relations between maladaptive and adaptive dimensions of perfectionism and bulimic symptoms and (b) to test an interactive model of perfectionism and perceived weight status for bulimic symptoms in a sample of African American female undergraduates. The sample consisted of 97 women at Time 1 and 70 women at Time 2 about 5 months later, with bulimic symptoms assessed at both time points. Results showed that maladaptive perfectionism, but not adaptive perfectionism, was uniquely related to bulimic symptoms in cross-sectional analyses. Tests of interaction effects indicated that maladaptive perfectionism interacted with perceived weight status to identify elevated bulimic symptoms such that women with high levels of maladaptive perfectionism who felt overweight exhibited the highest levels of bulimic symptoms, both concurrently and prospectively after controlling for Time 1 levels of bulimic symptoms. This study highlights the relevance of maladaptive perfectionism to bulimic symptoms in African American college women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Schizophrenia: A neural diathesis-stress model.

There is a substantive literature on the behavioral effects of psychosocial stressors on schizophrenia. More recently, research has been conducted on neurohormonal indicators of stress responsivity, particularly cortisol release resulting from activation of the hypothalamic-pituitary-adrenal (HPA) axis. This article integrates the psychosocial and biological literatures on stress in schizophrenia, and it offers specific hypotheses about the neural mechanisms involved in the effects of stressors on the diathesis. Both the behavioral and biological data indicate that stress worsens symptoms and that the diathesis is associated with a heightened response to stressors. A neural mechanism for these phenomena is suggested by the augmenting effect of the HPA axis on dopamine (DA) synthesis and receptors. Assuming the diathesis for schizophrenia involves an abnormality in DA receptors, it is proposed that the HPA axis acts as a potentiating system by means of its effects on DA. At the same time, DA receptor abnormality and hippocampal damage render the patient hypersensitive to stress. This neural diathesis-stress model is consistent with findings on prenatal factors and brain abnormalities in schizophrenia. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A test of the cognitive diathesis-stress model of depression in children: Academic stressors, attributional style, perceived competence, and control.

The cognitive diathesis–stress model of depression was tested in a sample of 439 children in grades 5 and 6. Attributional style and cognitions about academic competence and control over achievement were assessed before the occurrence of a potentially stressful event—receiving unacceptable grades on a report card. Depressive symptoms were assessed 1 week before the event, the morning after, and 5 days later. Replicating G. I. Metalsky, L. J. Halberstadt, and L. Y. Abramson (1987), stressor level and negative cognitions predicted depressive symptoms the morning after the event, controlling for initial symptom levels. Depressive symptoms 5 days later were predicted by the interactions of negative cognitions with stressors, supporting a cognitive diathesis–stress model. Students who reported a negative explanatory style or lack of academic control and competence expressed more distress after receiving unacceptable grades than did students without such cognitions.

Prepregnant weight and weight gain during pregnancy: relationship to functional status, symptoms, and energy

A 12-year-old girl with Sly disease (mucopolysaccharidosis VII; beta-glucuronidase deficiency), who is homozygous for the A619V mutation, had a successful allogeneic BMT, donored by an HLA-identical unrelated female to replace the deficient enzyme. Within 5 months after BMT, the enzyme activity of the recipient's lymphocytes increased to normal range. No signs of acute or chronic GVHD were observed. For the successive 31 months post-BMT, beta-glucuronidase activity in her lymphocytes was maintained at almost normal levels and excretion of glycosaminoglycans in the urine was greatly diminished. Ultrastructural findings demonstrated no abnormal vacuoles and inclusion bodies in the cytoplasm of her rectal mucosal cells. Coincident with the restoration of the enzyme activity, clinical improvement was dramatic. Especially notable were improvements in motor function. The patient was able to walk alone for a long time without aid, and she even became able to ride a bicycle and take a bath. In addition, recurrent infections of the upper respiratory tract and the middle ears decreased in frequency and severity, and dyspnea on exertion, severe snoring and vertigo have substantially improved. Thus, allogeneic BMT in this patient produced a better quality of life and provided a more promising outlook.     

Attributional formulation of depression as a diathesis-stress model: Metalsky et al. reconsidered.

Tests of the reformulated learned helplessness model of depression proposed by L. Y. Abramson et al (see record 1979-00305-001) have demonstrated correlations between attributional style and affective disturbance but have left open the question of whether an uncontrollable aversive event is a necessary part of the causal sequence in depression onset. G. I. Metalsky et al (see record 1979-08913-001) claimed to have tested this aspect of the model in a prospective study of examination success or failure. However, their finding of a significant attribution—mood correlation following failure but not following success—is considered to be ambiguous because they did not test the difference in correlation between the success and failure groups, which leaves the main hypothesis unresolved.

Perfectionism in chronic and state symptoms of depression.

Tested whether perfectionism dimensions uniquely predict chronic unipolar and chronic bipolar symptoms. A sample of 121 patients and former patients (mean age 46.1 yrs) completed the Multidimensional Perfectionism Scale, the General Behavior Inventory, and the Beck Depression Inventory. The results confirm that the perfectionism dimensions are related to chronicity of depression symptoms. Whereas self-oriented perfectionism was uniquely associated only with chronic unipolar symptoms, both socially prescribed and other-oriented perfectionism were uniquely associated with chronic bipolar symptoms. Importantly, these relationships remained significant after controlling for the effects of concurrent state depression. Finally, only socially prescribed perfectionism was uniquely associated with state depression. The results provide support for the position that perfectionism dimensions are important in both chronic. and state depression symptoms, but the perfectionism dimensions may differ in terms of their degree of association with various facets of depressive phenomena.

Perfectionism, perceived stress, drinking to cope, and alcohol-related problems among college students.

This study investigated the association between perfectionism (categorized by adaptive perfectionistic, maladaptive perfectionistic, or nonperfectionistic groups), perceived stress, drinking alcohol to cope, and alcohol-related problems in a large sample of college students (N = 354). Maladaptive perfectionists reported significantly higher levels of stress and drinking to cope than adaptive perfectionists and nonperfectionists. Adaptive perfectionists reported the fewest alcohol-related problems, suggesting that healthy levels of high standards may protect against drinking to cope with stress. Across all participants, a significant indirect effect for drinking to cope supported its role as a mediator between stress and alcohol-related problems. Structural equation modeling analyses supported the moderating role of perfectionism in this mediation model, such that maladaptive perfectionists were more likely to drink to cope under stress and report alcohol-related problems, whereas higher stress was associated with fewer alcohol-related problems among nonperfectionists. Additional analyses revealed higher stress levels for women and a stronger link between stress and drinking to cope for women compared to men. Future research directions as well as clinical implications regarding perfectionism, stress, drinking to cope, and alcohol-related problems are discussed.

A diathesis-stress model of posttraumatic stress disorder: Ecological, biological, and residual stress pathways.

The symptoms captured within the contemporary diagnostic definition of posttraumatic stress disorder (PTSD) have been studied for more than 100 years. Yet, even with increasingly advanced discoveries regarding the etiology of PTSD, a comprehensive and up-to-date etiological model that incorporates both medical and psychological research has not been described and systematically studied. The diathesis-stress model proposed here consolidates existing medical and psychological research data on etiological factors associated with PTSD into 3 causal pathways: residual stress, ecological, and biological. In combination, these pathways illuminate how PTSD might develop and who might be at higher risk for developing the disorder. Research and treatment implications related to the diathesis-stress model are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Authoritarianism, punitiveness, and perceived social status.

Ss were 101 introductory psychology students, 48 of whom were high scorers and 53 of whom were low scorers on an authoritarianism scale. A series of 24 separate stimulus cards of a semiprojective nature similar to the Rosenzweig pictures studied some of the interrelationships among authoritarianism, punitiveness, and status. The data indicate that low authoritarians respond to frustrators independently of their status. "… punitiveness is a function of both the personality of the individual and the particular stimulus environment that elicits the behavior."

Reciprocal relations between rumination and bulimic, substance abuse, and depressive symptoms in female adolescents.

The authors examined the reciprocal relations between rumination and symptoms of depression, bulimia, and substance abuse with longitudinal data from 496 female adolescents. Rumination predicted future increases in bulimic and substance abuse symptoms, as well as onset of major depression, binge eating, and substance abuse. Depressive and bulimic, but not substance abuse, symptoms predicted increases in rumination. Rumination did not predict increases in externalizing symptoms, providing evidence for the specificity of effects of rumination, although externalizing symptoms predicted future increases in rumination. Results suggest rumination may contribute to the etiology of depressive, bulimic, and substance abuse pathology and that the former two disturbances may foster increased rumination. Results imply that it might be beneficial for prevention programs to target this cognitive vulnerability. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Negative affect and self-report of physical symptoms: Two longitudinal studies of older adults.

The ability of negative affect (NA) to predict somatic complaints 6 months later was examined. State NA, including anxious affect (AA) and depressive affect (DA), was measured in 2 separate samples of older adults averaging 62 and 73 years of age. In the first study, DA reliably predicted later complaints, and a corresponding trend was noted for NA. The second study showed that state NA and its 2 constituent variables predicted somatic complaints associated with acute illness (e.g., colds) 6 months later. The second study also examined trait measures of the 3 predictor variables and found that NA and AA, but not DA, were associated with subsequent somatic complaints. However, these trait effects were less robust than those attributable to their state counterparts. The authors conclude that negative mood states are the more consistent predictors of later physical symptom reports. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Body weight and bulimia as discriminators of psychological characteristics among anorexic, bulimic, and obese women.

Bulimic women from underweight (n?=?20), normal-weight (n?=?31), and overweight (n?=?22) categories were compared with restrictor anorexics (n?=?20), normal controls (n?=?31), and obese Ss (n?=?22). Ss' mean age was 21.13 yrs. Each S was administered the Minnesota Multiphasic Personality Inventory (MMPI), Rotter's Internal–External Locus of Control scale, the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965), and the Semantic Differential scale. Bulimic women in all 3 weight categories exhibited greater psychopathology, more external locus of control, lower self-esteem, and lower sense of personal effectiveness than nonbulimic women at similar weight levels. The highest psychopathology, lowest self-esteem, and most external locus of control were found among the underweight bulimic women. Significant differences between bulimic women of different weight levels suggest the need for some modification of treatment approaches depending on the bulimic woman's weight level.

Perfectionism, attachment, and adjustment.

This research examined differences between types of perfectionists and whether perfectionism related to attachment, academic integration, and depression. University students completed the same attachment and perfectionism measures in two studies. In the 2nd study, measures of academic integration and depression were also used. Replicated cluster analyses revealed 3 groups of perfectionists: adaptive, maladaptive, and nonperfectionists. Attachment predicted type of perfectionist, with adaptive perfectionists reporting more secure attachments than did maladaptive perfectionists. Adaptive perfectionists also had better academic integration than maladaptive perfectionists. Maladaptive perfectionists, on average, reported depression in the clinically significant range. Results revealed academic and emotional benefits of adaptive perfectionism, contrasted with the adverse emotional effects and no academic advantages of maladaptive perfectionism.

Modeling individual differences in perceptual and attentional processes related to bulimic symptoms.

Attentional and perceptual differences between women with high and low levels of bulimic symptoms were studied with techniques adapted from cognitive science. Stimuli were pictures of young women varying in body size and facial affect. A multidimensional scaling analysis showed that the high symptom women were significantly more attentive to information about body size and significantly less attentive to information about affect. In prototype classification tasks, the high-symptom women used significantly more information about body size and significantly less information about affect. There were strong associations between individual differences in attention in the similarity task and decision making in the classification tasks. The study shows the potential utility of cognitive science methods for the study of cognitive factors in psychopathology. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Appraisal, coping, health status, and psychological symptoms.

Examined the relation between personality factors (mastery and interpersonal trust), primary appraisal (the stakes a person has in a stressful encounter), secondary appraisal (options for coping), 8 forms of problem- and emotion-focused coping, and somatic health status and psychological symptoms among 75 married couples (aged 26–54 yrs). Measures included the Hopkins Symptom Checklist, Rosenberg Self-Esteem Scale, and items from the Rotter Trust Scale. It was assumed that appraisal and coping processes should be characterized by a moderate degree of stability across stressful encounters for them to have an effect on somatic health status and psychological symptoms. These processes were assessed in 5 stressful situations that Ss experienced in their day-to-day lives. Certain processes (e.g., secondary appraisal) were highly variable, whereas others (e.g., emotion-focused forms of coping) were moderately stable. Mastery and interpersonal trust, primary appraisal, and coping variables (aggregated over 5 occasions) explained a significant amount of the variance in psychological symptoms but not somatic health status.

Linking perceived unfairness to physical health: The perceived unfairness model.

Can perceiving unfairness influence physical health? To address this question the authors propose the Perceived Unfairness Model, synthesized from psychological and epidemiological research. The model starts from the premise that perceiving unfairness, directed at beings to which the perceiver is emotionally attached, activates a cascade of psychological and physical processes. This cascade may be experienced by low or high status group members, and by the target or observer of the perceived unfairness. With repeated episodes, the effects of perceiving unfairness may accumulate and compromise physical health. Whether perceiving unfairness is potentially toxic or benign is a function of two key components of social location: identity relevance and helplessness to redress the unfairness. The authors conclude by discussing directions for developing the model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Why software testing is sometimes ineffective: Two applied studies of positive test strategy.

The term positive test strategy describes the tendency to test a hypothesis with test cases that confirm (i.e., aim to support) rather than disconfirm the hypothesis. Most demonstrations of this phenomenon have involved relatively abstract problems. The authors suggest that people use a positive test strategy in a more applied setting as well, that is, in computer software testing. In 2 experiments, they examined how Ss with varying expertise performed functional testing of software. There was substantial evidence of the use of a positive test strategy: Ss tended to test only those functions and aspects of the software that were specifically described in the specifications as what the software was supposed to do. This effect was only partially mitigated by increasing expertise among testers and by more complete program specifications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Counselor trainees' perceptions of supervisor roles: Two studies testing the dimensionality of supervision.

Two studies were conducted to assess the dimensionality of supervision. The purpose of Study 1 was to identify the salient dimensions of supervision from the counselor trainee's perspective and to determine if dimensions for trainees corresponded to the dimensions found previously for supervisors. In doing so the dimensionality and construct validity of Bernard's (1979) model was examined by using 15 doctoral trainees. For Study 2 Bernard's model was expanded to incorporate the self-supervisor role and was tested in combination with Littrell, Lee-Borden, and Lorenz's (1979) model. Counselor trainees from a master's (n?=?25) and a doctoral (n?=?23) program participated. The three dimensions that emerged in Study 1 and in Study 2 were remarkably consistent in content and label across the two studies. In terms of dimensionality, Bernard's model and the extended model were modestly supported, whereas Littrell et al.'s model received minimal support. Little evidence was found to suggest that trainees from master's and doctoral programs differed at all in terms of their cognitive maps of supervision. Implications and limitations of the studies were discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
