Psychophysiological differences between subgroups of social phobia.

Individuals meeting criteria of the revised third edition of Diagnostic and Statistical Manual for Mental Disorders (American Psychiatric Association, 1987) for social phobia with a fear of speaking in front of people were subdivided into those with (n?=?16) and without (n?=?14) avoidant personality disorder (APD). These individuals and nonanxious controls (n?=?22) spoke in front of a small audience while speaking time, subjective anxiety, fearful thoughts, and electrocardiographic and respiratory measures were recorded. Controls spoke for longer than either social phobia group. Those with social phobia and APD reported more subjective anxiety and more fear cognitions than the other two groups; phobic individuals without APD showed greater heart rates in the phobic situation than either social phobics with APD or controls. The latter two groups did not differ in heart rate. These results indicate incongruent subjective and heart rate responses to the feared situation. A similar pattern of results was found when participants were divided into generalized and specific social phobia groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Blood-injury-injection phobia and dental phobia

The present study was carried out to explore the relation between BII phobia and dental phobia. An additional aim was to determine the fainting tendency of dental phobics and BII phobics during an invasive treatment procedure. Participants were 63 patients undergoing treatment in a dental fear clinic, and 173 patients undergoing dental surgery in a university hospital. They completed measures on fears of particular medical and dental stimuli, fainting history, general trait anxiety, dental anxiety, BII anxiety, BII avoidance, and a questionnaire aimed to define a phobia based on DSM-IV criteria. Immediately after treatment information was obtained on exposures to blood or injections, state anxiety, and feelings of faintness during treatment. The results did not indicate any significant relationship between measures of dental anxiety and BII anxiety or BII avoidance. However, 57% of the dental phobic patients could also be classified as BII phobic. The proportion of dental phobics who reported fainting episodes in their past was similar to that of the BII phobics (37%), but none of the participants fainted during treatment. It is concluded that, albeit the level of co-occurrence for both types of phobias is high, dental phobia should be considered as a specific phobia, independent for the BII subtype within DSM-IV. Further, the findings are inconsistent with the notion that individuals with BII phobia have a remarkably high tendency to faint in the presence of their phobic stimuli.     

Age of onset in different phobias.

The age of onset, other background data, and measures from behavioral avoidance tests were studied in 370 phobic patients. They belonged to six different categories: agoraphobia (n?=?100), social phobia (n?=?80), claustrophobia (n?=?40), animal phobia (n?=?50), blood phobia (n?=?40), and dental phobia (n?=?60). Results showed that animal phobia had the earliest onset age (7 years), followed by blood phobia (9 years), dental phobia (12 years), social phobia (16 years), claustrophobia (20 years), and agoraphobia (28 years). The groups also differed in marital and occupational status, heart rate, anxiety experiences during the behavioral test, and general fearfulness. On the whole, agoraphobia and animal phobia stood out as the extremes on many measures. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

MMPI differences between alcoholics and drug abusers: Effect of age and race.

Inpatients in Veterans Administration substance-abuse treatment programs voluntarily took the Minnesota Multiphasic Personality Inventory (MMPI) as part of a routine clinical evaluation. The alcohol-dependence-only group (n?=?207) were older (M?=?49.6 years) and had a higher percentage of White Ss (72.9%) than did either the drug-dependence group (n?=?49, M?=?32.9 years, Whites?=?53.1%) or a mixed alcohol- and drug-dependence group (n?=?160, M?=?35.0 years, Whites?=?60.0%). Previously reported differences between alcoholics and drug abusers in depression and psychopathy were obtained when age and race were not used as covariates, but no differences were found when the effects of age and race were statistically controlled. Mixed alcohol and drug abusers had somewhat more pathological MMPI scores than did alcoholics, even when effects due to age and race were partialed out.

The Brief Symptom Inventory: Measuring psychological distress in spinal cord injury.

Explored the appropriateness of the Brief Symptom Inventory (BSI) as a measure of psychological distress among 79 traumatic spinal cord injured (SCI) patients (aged 18–70 yrs) and emphasized the limitations of using the BSI as a replacement for the SCL-90—Revised (SCL-90—R). Ss' BSI scores were compared with a nonpatient normative group (N?=?974). Ss were significantly more psychologically distressed in somatization, depression, and phobic anxiety than the normative group. However, several somatization symptoms endorsed by these Ss are common physical effects of SCI rather than psychosomatic complaints. When comparing BSI and SCL-90—R scores of the same Ss, significant statistical differences were found with respect to the level of psychological distress being reported by each test. The BSI may not represent an equivalent abbreviated form of the SCL-90—R for the SCI population. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Abusing, neglectful, and comparison mothers' responses to child-related and non-child-related stressors.

Studied mothers with a previous history of child abuse (n?=?12) or child neglect (n?=?12) or with no known previous history of child maltreatment (n?=?12) who participated in an experiment designed to assess reactions to a number of aversive stimuli. Mean ages of the abusive, neglectful, and comparison Ss were 25.08, 26.90, and 26.10 yrs, respectively. Both child-related and non-child-related stressful stimuli were presented, and a number of dependent variables, including measures of attributional style and annoyance, were employed to assess the situational specificity of responding. Analysis of the attributional data indicated that abusing Ss consistently ascribed more malevolent intentionality to their child than the other Ss. Situation and interaction effects were also present for the attributional measure. Results from the process annoyance measures indicate that highly significant situation effects were present. In addition, the abusing mothers were more annoyed across both the social and nonsocial stressors, suggesting that a generalized pattern of hyperresponsivity exists in this group. Results are interpreted within a recently formulated cognitive-behavioral model of child abuse. (33 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Avoidant personality disorder and the generalized subtype of social phobia.

Social phobia and avoidant personality disorder (APD) may be given as comorbid diagnoses. However, it is not known if the labels provide independent, useful diagnostic information. The authors classified social phobics by social phobia subtype and presence of APD. Generalized social phobics with and without APD (ns?=?10 and 10) and nongeneralized social phobics without APD (n?=?10) were distinguished on measures of phobic severity. The generalized groups also showed earlier age at onset and higher scores on measures of depression, fear of negative evaluation, and social anxiety and avoidance than did the nongeneralized group. APD criteria of general timidity and risk aversion were more frequently endorsed by social phobics with AD. The data suggest that both the generalized subtype of social phobia and the presence of APD do provide useful diagnostic information, but the additional diagnosis of APD may simply identify a severe subgroup of social phobics.

Outpatient group treatment of chronic pain: Effects of spouse involvement.

Evaluated the efficacy of outpatient group treatment of chronic pain and the effect of spouse involvement in treatment in chronic pain patients ranging in age from 23 to 69 yrs who were randomly assigned to couples group treatment (n?=?17), patient-only group treatment (n?=?14), or waiting-list controls (n?=?12). 29 Ss had low back pain; the remaining Ss reported pain in the knee, arm, leg, hip, head, and phantom limb. The Ss completed the MMPI—168 and measures of health-related psychosocial and physical dysfunction and marital satisfaction. Results indicate that the 16-hr cognitive-behavioral program produced reductions in pain, somatization, spouse-observed pain behavior, physical and psychosocial dysfunction, spouse-rated dysfunction, and utilization of health care resources. Depression was not affected by treatment. Spouse involvement did not facilitate response to treatment on any variables. Also, Ss in the individual condition only showed improved marital satisfaction. All treatment gains were maintained at 3-mo to 7-mo follow-ups. Results indicate that brief outpatient treatment can significantly ameliorate chronic pain problems, and spouse involvement is not essential for a positive response to treatment.

Psychopathology of social phobia and comparison to avoidant personality disorder.

Studied the clinical manifestations of social phobia in a diagnosed sample of 21 social phobics (aged 21–53 yrs). Social phobia was found to be a chronic and pervasive condition affecting a variety of life areas and producing significant emotional distress. In a 2nd study, individuals with a diagnosis of social phobia or avoidant personality disorder were compared using a subsample of 10 socially phobic Ss and a sample of 8 Ss with avoidant personality disorder (aged 30–60 yrs). Although physiological reactivity and cognitive content were essentially the same for both groups in a number of situational tasks, those Ss with a diagnosis of avoidant personality disorder were found to be more sensitive interpersonally, and exhibited significantly poorer social skill than did the social phobic Ss. Results are discussed in relation to Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria for social phobia, the significance of social phobia as a clinical syndrome, and the research and treatment implications of the difference found between individuals with a diagnosis of social phobia and those with avoidant personality disorders.

A factor analysis of personality and fear variables in phobic disorders.

Investigated the fears and personality traits of 225 individuals (mean age 32.5 yrs) experiencing 1 of 4 phobic conditions—agoraphobia, claustrophobia, social phobia, or some other specific phobia. Several Fear Survey Schedule variables and the personality scales of the Guilford-Zimmerman Temperament Survey were factor analyzed. Five factors were extracted that were consistent with previous findings, which were related to each of 4 independent variables: Treatment Subgroup, Diagnosis, Age, and Sex. Clinic and private clients did not differ significantly on any factor, nor did age account for any meaningful change in factor scores. The diagnostic groups scored discrepantly on 2 factors: Social Activity and Cognitive Introversion, and Fear of Sensory Stimuli. Females differed significantly from males on Femininity and Miscellaneous Fears. Results are discussed in terms of past research and possible ramifications for the clinical practice of behavior therapy.

External validity of laboratory fear assessment: Implications from two case studies.

Exposed 1 snake-phobic woman and 1 spider-phobic woman to a live snake or spider after they received systematic desensitization. In one assessment condition the 2 Ss were asked to approach and handle a caged snake or spider as in the traditional behavioral approach test, whereas in the other condition the Ss were exposed to the uncaged phobic stimuli. Both Ss manifested substantially greater physiological and cognitive distress while looking at the uncaged stimuli from a distance of 30 ft than when actually touching the caged snake or spider. Although both Ss were able to touch the caged snake or spider, they still reported being unable to engage in behaviors that were previously inhibited because of their phobia. Both Ss emphasized the importance of feeling in control when the phobic stimulus was caged but feeling out of control when the phobic stimulus was uncaged. Implications for the external validity of the behavioral approach test are discussed. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Standardization of the Wechsler Adult Intelligence Scale—Revised for persons 75 years and older.

This project expanded the Wechsler Adult Intelligence Scale—Revised (WAIS—R) normative tables for the Verbal, Performance, and Full Scale IQs and age-corrected subtest scores to persons aged 75 yrs and older. A sample of 130 normal volunteers was selected according to 1983 census data on the variables of age, education, sex, and race. Means for age and education were 81.24 yrs (SD?=?5.24) and 9.54 yrs (SD?=?2.50). There were 74 White women, 42 White men, 9 Black women, and 5 Black men. Ss lived in the states of Kansas (60.7%), Missouri (34.6%), and Iowa (4.6%), with 90% residing in urban centers and 10% in rural communities. All Ss were administered a complete WAIS—R by trained examiners. On the basis of the raw scores, Verbal, Performance, and Full Scale IQ conversion tables were developed separately for persons 75–79 yrs of age (n?=?60) and aged 80 yrs and older (n?=?70). Conversion tables (M?=?10; SD?=?3) for age-corrected scaled scores were also developed for both age groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The validity of the DSM-III posttraumatic stress disorder classification as applied to children.

Tested three groups of children: The first group (n?=?231) presented with posttraumatic stress disorder (PTSD), the second group (n?=?32) presented with simple phobia (i.e., test phobia), and the third group (n?=?35) was made up of nonclinical controls. The subjects marked the Revised Children's Manifest Anxiety Scale (RCMAS), Children's Depression Inventory (CDI) and their conduct was rated against the Conners Teacher Rating Scale (CTRS) criteria. A multivariate analysis of variance (MANOVA) evinced significant group and gender differences. No significant interaction effects were noted. Univariate F tests and Bonferroni posttests revealed that the PTSD cases evinced markedly higher RCMAS, CDI, and CTRS scores than their phobic and nonphobic peers. Analogously, the RCMAS and CDI scores of the phobia cases were appreciably greater than the control groups. On the other hand, the CTRS scores of the test phobia and control groups were not significantly different. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mother–child interactional style in abuse, neglect, and control groups: Naturalistic observations in the home.

Examined mother–child interactional patterns in an urban environment. Three groups of mothers (n?=?12/group) were included in the study: (a) Ss with a known history of child abuse, (b) Ss with a known history of child neglect, and (c) Ss with no known history of child maltreatment. Ss and their children were observed in their homes on 3 consecutive days for 90 min each day. Interactions were described via a coding system of 11 major interactional patterns; dependent variables included verbal and nonverbal behaviors as well as measures of total interaction. Results indicate that the groups differed on several variables. Dysfunctional Ss showed significantly fewer positive behaviors than did the controls on verbal and nonverbal measures. Also, the abusive Ss showed significantly higher rates of verbal and physical aggression; the neglectful mothers had the lowest overall rates of interaction. The maltreated children also exhibited fewer positive behaviors and more aggressive behaviors. Results are discussed in terms of current theories of child maltreatment and of the treatment of dysfunctional families. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Examination of affect and egotism as mediators of bias in causal attributions.

Investigated the relationship between affect and self-attributions following positive (P) and negative (N) behavioral outcomes. In the presence (high publicity) or absence (low publicity) of observers, 63 college students delivered therapeutic instructions that were expected to have a P or N effect and that resulted in a P or N effect on a supposedly phobic patient. Principal findings were that (a) Ss made greater attributions to self for P than for N outcomes; (b) both during and following performance, P outcome Ss reported more P and less N affect than did N outcome Ss; (c) both during and following performance, P outcome Ss reported greater feelings of egotism than did N outcome Ss; and (d) under N outcome conditions, high publicity Ss made lower self-attributions and subsequently also reported greater feelings of egotism than did low publicity Ss. The results support the notion that the observed P–N outcome differences in self-attributions reflect motivational biases in the causal inference process.

WAIS—R factor structure in psychiatric and general medical patients.

Examined the factor structure of the WAIS—R in a sample of 200 general medical (GM) patients and 271 psychiatric patients. The mean age of the Ss was 38.9 yrs. Results of 2- and 3-factor principal factor solutions with varimax rotations were compared to the factor structure of the WAIS—R normative sample (n?=?1,880) and a sample of vocational counseling patients (n?=?84), as well as an additional sample of psychiatric patients (n?=?114). Across all of these samples, coefficients of congruence for the 1st 2 factors (Verbal, Performance) were .97 or greater, and coefficients of congruence for the 3rd factor (Freedom From Distractability) ranged from .93 to .97. Results indicate that the WAIS—R has a robust factor structure and provides empirical evidence for the existence of Verbal, Performance, and Freedom From Distractability factors on the WAIS—R in psychiatric and medical populations.

Phobia-relevant illusory correlations: The role of phobic responsivity.

The authors investigated the role of phobic responsivity in the generation of phobia-relevant illusory correlations. As a means of disentangling the contributions of prior fear and elicited fear responses, half of a group of phobic women received 1 mg alprazolam (n?=?21), and half received a placebo (n?=?22). A group of nonfearful women (n?=?24) was included to control for prior fear per se. Participants were exposed to slides of spiders, weapons, and flowers that were randomly paired with a shock, a siren, or nothing. Postexperimental covariation estimates and on-line outcome expectancies were assessed. Irrespective of both prior and elicited fear, participants postexperimentally overassociated spiders and shock. Yet, only women with spider phobia displayed a persisting fear-confirming expectancy bias. This bias was similar for the placebo and alprazolam groups. Thus, the bias appeared to be due to preexisting phobogenic beliefs, whereas phobic responsivity played a negligible role. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Empirically derived characteristics of psychiatric inpatients with DSM-III diagnoses of schizophreniform disorder.

165 18–50 yr old active-duty military, male, psychiatric inpatients with DSM-III diagnoses of schizophreniform disorder (n?=?71), schizophrenia (n?=?40), bipolar disorder—manic type (n?=?25), and unipolar depression (n?=?29) were compared on a variety of demographic, behavioral, and personality (MMPI) measures to determine the unique characteristics of schizophreniform disorder. Schizophreniform and schizophrenic Ss did not differ on any of the demographic or behavioral measures, but they differed significantly on the MMPI when age was controlled for by means of multivariate ANCOVA. Conversely, schizophreniform and bipolar manic Ss differed on the demographic correlates and on 1 behavioral measure (i.e., hyperactivity) but failed to differ on the MMPI. Schizophreniform and unipolar Ss, on the other hand, differed widely on all 3 sets of correlates. It is suggested that some schizophreniform patients will likely satisfy the criteria for schizophrenia if the diagnostician waits long enough (i.e., 6 mo).

Psychological profiles of purging bulimics, repeat dieters, and controls.

In Study 1, 29 female undergraduates who met Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria for bulimia were compared with 2 nonbulimic groups drawn from the same S pool. One group consisted of 27 Ss who reported feeling dissatisfied with their weight and engaged in repeated dieting attempts but not bulimic behavior. The 2nd comparison group consisted of 27 Ss who reported feeling satisfied with their weight and not dieting within the last year. Measures included the Minnesota Multiphasic Personality Inventory (MMPI), Personal Attributes Questionnaire, and Tennessee Self-Concept Scale. All Ss scored in the normal range, but bulimics scored significantly higher than the 2 comparison groups on a number of clinical scales. Also, the bulimics and repeat dieters reported lower self-esteem than did the nondieting group. The major discriminating variables—psychopathic deviance, mania, and physical self-esteem—separated all 3 groups and accounted for 78% of the explained variance. Study 2 was conducted with 27 current bulimic women, 12 former bulimics, 29 nondieters, and 31 repeat dieters. Results confirm the importance of physical self-esteem and psychopathic deviance in differentiating between groups. This study also revealed that bulimics engaged in sexual activities and in the adolescent acting-out behaviors of drug and alcohol use more frequently, and at an earlier age, than did the 2 comparison groups. Implications for therapeutic interventions are discussed. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pseudomemory in hypnotized and task-motivated subjects.

Highly hypnotizable hypnotized (HYP; n?=?16) and task motivated (TM; n?=?13) Ss received pseudomemory suggestions (M. T. Orne, 1979). TM Ss reported being more awake and motivated than did HYP Ss and were more likely to pass the target noise suggestion. However, 69% of Ss in both conditions who passed the noise suggestion reported pseudomemories. Pseudomemory rate (69% for HYP Ss and 46% for TM Ss) was not reduced by informing Ss that they could distinguish reality and fantasy in a state of deep concentration. At final inquiry, after deep concentration, pseudomemories remained stable (75% for HYP Ss and 54% for TM Ss). As predicted, HYP Ss reported more unsuggested noises and more pseudomemories of novel noises than did TM Ss. Ss who reported pseudomemories were more confident in the accuracy of their memories than were Ss who reported that the suggested noises were imagined.
