A controlled comparative investigation of psychological treatments for chronic sleep-onset insomnia

A sample of physician-referred chronic insomniacs was randomly allocated to either progressive relaxation, stimulus control, paradoxical intention, placebo or no treatment conditions. Treatment process and outcome were investigated in terms of mean and standard deviation (night to night variability) measures of sleep pattern and sleep quality. Only active treatments were associated with significant improvement, but the nature of treatment gains varied. In particular, stimulus control improved sleep pattern, whereas relaxation affected perception of sleep quality. All improvements were maintained at 17 month follow-up. Results are discussed with reference to previous research and guidelines are given for clinical practice.     

Private-sector care for chronically mentally ill individuals. The more things change, the more they stay the same

Two profit-making industries, nursing homes and board-and-care homes, care for about one million chronic mental patients. This care is primarily custodial and probably not very different from the care patients received in the public sector prior to deinstitutionalization. Moreover, certain characteristics of privately owned facilities encourage poor patient care so as to maximize profit. The problem could be ameliorated if chronic mental patients were strong and informed consumers or if the public sector strongly regulated proprietary care. However, neither of these two conditions now hold. Perhaps the apparent difficulties in significantly improving care for chronically mentally ill individuals despite seemingly major changes in policy reflect a fundamental problem in overall social policy--a reluctance to care for chronically indigent individuals of all kinds.     

Testing between the TRACE model and the fuzzy logical model of speech perception

The TRACE model of speech perception (McClelland & Elman, 1986) is contrasted with a fuzzy logical model of perception (FLMP) (Oden & Massaro, 1978). The central question is how the models account for the influence of multiple sources of information on perceptual judgment. Although the two models can make somewhat similar predictions, the assumptions underlying the models are fundamentally different. The TRACE model is built around the concept of interactive activation, whereas the FLMP is structured in terms of the integration of independent sources of information. The models are tested against test results of an experiment involving the independent manipulation of bottom-up and top-down sources of information. Using a signal detection framework, sensitivity and bias measures of performance can be computed. The TRACE model predicts that top-down influences from the word level influence sensitivity at the phoneme level, whereas the FLMP does not. The empirical results of a study involving the influence of phonological context and segmental information on the perceptual recognition of a speech segment are best described without any assumed changes in sensitivity. To date, not only is a mechanism of interactive activation not necessary to describe speech perception, it is shown to be wrong when instantiated in the TRACE model.     

Cerebral laterality and depression: differences in perceptual asymmetry among diagnostic subtypes

Examined the influence of diagnostic subtype of depression on perceptual asymmetry for dichotic listening and visual tachistoscopic tasks. A total of 65 unmedicated patients with major depressive disorders and 30 normal controls were tested on a verbal and nonverbal task in each modality. Patients diagnosed according to the DSM-III with melancholia had abnormal perceptual asymmetry for dichotic nonsense syllable and complex tone tasks. In contrast, patients having a nonmelancholic "atypical depression" (reactivity of mood with preserved pleasure capacity and associated features) did not differ from normal controls on these tasks, but had an increased incidence of left handedness. Bipolar depression (history of hypomania) differed from unipolar depression in showing abnormal perceptual asymmetry for a tachistoscopic dot enumeration task. Alterations of perceptual asymmetry in melancholia and bipolar depression were consistent with hypothesized right hemisphere dysfunction.     

Family Functioning of Male Alcoholics and Their Female Partners during Periods of Drinking and Abstinence

Family functioning of 20 alcoholic male veterans and their female partners was assessed in relation to drinking (wet) and abstinent (dry) intervals. Repeated measures analyses performed on the McMaster Family Assessment Device (FAD) indicated that on all 7 scales of the FAD, alcoholics and their mates perceived family functioning to be better during dry than wet periods. In contrast to their alcoholic mates, female partners gave healthier ratings to all FAD scales except Roles in the dry condition and Affective Involvement in the wet condition. According to published cutoff scores for healthy and unhealthy family functioning, alcoholics as a group viewed their wet and dry family functioning as unhealthy, although the female group regarded the family's dry Problem Solving and Behavioral Control as healthy. These findings suggest that the family functioning of alcohol-involved couples is biphasic, oscillating between drinking and abstinent periods.     

Cardiovascular reactivity and interpersonal influence: active coping in a social context

Previous studies have demonstrated that effortful attempts to secure positive outcomes or avoid negative outcomes produce significant increases in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Although these effects of active coping on cardiovascular reactivity are central in current psychosomatic theories, virtually all of the research to date has used impersonal, asocial tasks. Our two studies examined the cardiovascular effects of effortful attempts to influence other people. In Study 1, male subjects attempting to influence the opinions of their discussion partner to improve their own chances of winning money displayed significantly greater SBP, DBP, and HR reactivity. In Study 2, we obtained similar effects on SBP and DBP reactivity in men and women, while both preparing an influence attempt and making that attempt. Furthermore, reactivity levels were larger as the magnitude of incentive for successful persuasion increased. Implications of this interpersonal equivalent of active coping for the development of cardiovascular disease are discussed.     

Psychological test signs of borderline personality disorder: a review of the empirical literature

Recent empirical work aimed at identifying test signs of borderline personality disorder is reviewed. The review focuses on commonly employed clinical tests, including the Wechsler Adult Intelligence Scale (WAIS), the Rorschach, and the Minnesota Multiphasic Personality Inventory (MMPI). Possible test signs are considered in relation to their sensitivity to and specificity for the diagnosis and in relation to the criteria of DSM-III, which define the disorder. Although consistent patterns of potentially useful test signs have begun to appear, methodological difficulties have hampered any subsequent development of clinically useful indices. Greater attention to sample size and its composition and definition as well as demonstrations of adequate reliability and predictive utility are required for further development of these signs.     

Reinterpreting the Myers-Briggs Type Indicator From the Perspective of the Five-Factor Model of Personality

The Myers-Briggs Type Indicator (MBTI; Myers & McCaulley, 1985) was evaluated from the perspectives of Jung's theory of psychological types and the five-factor model of personality as measured by self-reports and peer ratings on the NEO Personality Inventory (NEO-PI; Costa & McCrae, 1985b). Data were provided by 267 men and 201 women ages 19 to 93. Consistent with earlier research and evaluations, there was no support for the view that the MBTI measures truly dichotomous preferences or qualitatively distinct types; instead, the instrument measures four relatively independent dimensions. The interpretation of the Judging-Perceiving index was also called into question. The data suggest that Jung's theory is either incorrect or inadequately operationalized by the MBTI and cannot provide a sound basis for interpreting it. However, correlational analyses showed that the four MBTI indices did measure aspects of four of the five major dimensions of normal personality. The five-factor model provides an alternative basis for interpreting MBTI findings within a broader, more commonly shared conceptual framework.     

A Test of Bipolar and Androgyny Perspectives of Masculinity and Femininity: The Effect of Participation in an Outward Bound Program

ABSTRACT The purposes of the present investigation are to examine theoretical issues in androgyny theory by testing the effect of participation in the Outward Bound program on measures of masculinity (M) and femininity (F) Bipolar conceptualizations of MF posit that an increase in either M or F must lead to a decrease in the other, whereas androgyny theory posits M and F to be independent constructs Consistent with a priori predictions based on the nature of the Outward Bound program, participation substantially enhanced M and had a small positive effect on F The results were reasonably consistent for male and female participants, for single-sex and mixed-sex groups, and across responses to three different MF measures Results support the androgyny interpretation of MF and demonstrate the effectiveness of the Outward Bound program in changing MF The results contradict the bipolar perspective that an increase in M must be accompanied by a decrease in F
