Individual difference variables, affective differentiation, and the structures of affect.

Methodological arguments are usually invoked to explain variations in the structure of affect. Using self-rated affect from Italian samples (N=600), we show that individual difference variables related to affective differentiation can moderate the observed structure. Indices of circumplexity and congruence coefficients to the hypothesized target were used to quantify the observed structures. Results did not support the circumplex model as a universal structure. A circular structure with axes of activation and valence was approximated only among more affectively differentiated groups: students and respondents with high scores on Openness to Feelings and measures of negative emotionality. A different structure, with unipolar Positive Affect and Negative Affect factors, was observed among adults and respondents with low Openness to Feelings and negative emotionality. The observed structure of affect will depend in part on the nature of the sample studied.

Ego function assessment of schizo-affective patients as compared to schizophrenic and affective psychotic patients.

A 1-year sample of consecutively admitted patients between 18 and 40 years of age is studied. Psychopathology has been elicited by the Schedule for Affective Disorders and Schizophrenia (SADS), and diagnoses have been set according to Research Diagnostic Criteria (RDC). The sample consists of 57 cases with schizophrenia, 8 cases with schizo-affective psychosis and 23 cases with affective psychoses. Bellak's Ego Function Assessment Test was given to all these patients. The test does not show any significant differences between the schizo-affective and the schizophrenic groups. Some significant differences are found between the schizo-affective group and the group of affective psychosis. The findings do not validate schizo-affective psychosis as a diagnostic category.

Affect in psychoanalytic theory: discussion of André Green's 'on discriminating and not discriminating between affect and representation'.

André Green's 1999 programmatic essay on affect and representation, an attempt to extend Freud's model of the neuroses (where affect and representation have different vicissitudes) to non-neurotic cases is submitted to critical reading. Green wishes to restore the importance of representation; to use the second topographical theory, where id, psychical impulse and object-cathexis replace the unconscious and the ideational representation in order to conceptualize borderline disturbance, and to show how ultimately the 'non-discrimination' affect-representation obtains in non-neurotic cases as well. The author, interested in the question posed in Green's essay as to what we have to sell our borderline patients, addresses the various reasons why this project fails. Among the problematic points are the paradox of Green's model of unconscious affect, that does not allow the analyst to generate meaning with borderline patients, the view of 'representation' as replacing presence and perception of the object that does not allow the analyst to be a non-absent object, and the inability to conceptualize affect-representatives and to work out the definition of affect as 'the anticipation of a meeting with the other's body' which does not allow the analyst to function as an 'anticipatory object' or 'an object of affect'.

On a disturbance of affectivity in schizophrenic adolescents: implications for affect theory.

As recently as 1969 Loeb stated, "Not only has adolescent schizophrenia been largely ignored by the clinician and research worker but until recent years the entire subject of adolescence had received scant attention" (p. 462). Since that time, a number of investigators have attended to similarities and differences between the schizophrenic syndrome, as a whole, and schizophrenia as it appears in adolescence. One of the findings that has been alluded to by some authors concerns the notion that affect is less severely disturbed, especially in the dimension of affective responsiveness, in adolescent schizophrenics (Sands, 1956). Observations by the author and others suggest that greater attention be paid to the variety of affectivity to delineate this area of symptomatology, which both Kraepelin and Bleuler considered so fundamental and typical in their designations of dementia praecox and schizophrenia. Indeed the purpose of this study concerns the description and dynamic understanding of a typical disturbance of affectivity in adolescent schizophrenics. This disturbance is characterized by a quality of affective communication in which the patient relates to the people around him in a superficial, socially acceptable, receptionist-like manner which induces in the observer the impression that the individual's genuine feelings are not prominent. For want of a better term, we may designate this affective state "airline-hostess affectivity" (A.H.A.). The disturbance is not exclusive to adolescent schizophrenics but can also be observed in young adults too before a phase of chronic adaptation to the schizophrenic process.

Transient sensory, cognitive and affective phenomena in affective illness. A comparison with complex partial epilepsy.

Behavioural changes have often been noted in patients with epilepsy. This study investigated the converse phenomenon--the occurrence of transient sensory, cognitive and affective changes resembling those described by epileptics, in affectively ill patients. Forty-four patients with affective illness, 37 with complex partial seizures, and 30 hypertensive controls were interviewed to determine the lifetime occurrence of these phenomena. Such symptoms occurred frequently in association with episodes of affective illness and epilepsy, but were rare in controls. Visual, auditory, olfactory and epigastric symptoms, illusions, jumbled thoughts and amnesia were common to both epilepsy and affective illness. Greater numbers of symptoms were associated with better response to lithium and tricyclic antidepressants. Transient sensory, cognitive, and affective phenomena may be more common in affective illness and other psychiatric conditions than is generally recognised, and may be clues to the underlying pathophysiology of these conditions.

The role of negative affect and positive affect in stress, depression, self-esteem, assertiveness, Type A behaviors, psychological health, and physical health.

Dua (1989) constructed the Thoughts and Real-Life Experiences Scale (THARL) to assess the degree of positive and negative affect experienced by people as a result of their thoughts and day-to-day experiences. This monograph reports on a number of studies designed to investigate the relationship between negative and positive affect caused by thoughts and day-to-day experiences and psychological health, psychological problems, and physical health. Results showed that a preponderance of self-reported negative affect was related to higher levels of stress, depression, poor psychological well-being, poor psychological health, lower self-esteem and poor self-reported retrospective physical health. A preponderance of negative affect was associated with only one of the two measures of prospective physical health, namely, the number of visits to doctors for medical problems over a period of 4 weeks. Positive affect was not associated with either self-esteem or physical health. Assertiveness and Type A/B behaviors were not associated with either negative or positive affect. Also, of the two measures of negative affect, that caused by thoughts seemed to be a better predictor of health, well-being, and psychological problems than that caused by day-to-day experiences.

Development of a measure that integrates positive and negative affect and personality: the Comprehensive Personality and Affect Scales.

The development, reliability and validity of a new measure of personality and affect, the Comprehensive Personality and Affect Scales (COPAS) was investigated in three studies of college students. In study 1, the factor structure of personality, negative affect, and positive affect was assessed, with five-factors found in each of the three analyses. Fifteen scales (Personality: Emotionality, Extroversion, Openness, Conscientiousness, and Agreeableness; Negative Affect: Depression, Hostility, Agitation, Anxiety, and Social Anxiety; Positive Affect: Contentment, Joy, Love, Vigor, and Excitement) were constructed based on results of the factor analysis. Confirmatory factor analyses confirmed the measurement model. In study 2, the reliability and construct validity of each of the 15 factor-derived scales was assessed in both referred and non-referred college students. Study 3 investigated the utility of the COPAS scales in differentiating referred and non-referred college students. Results indicated that reliability of the scales was good to excellent, while convergent and divergent validity was good for most scales. The COPAS scales were also shown to differentiate between referred and non-referred samples of college students. Overall, the COPAS was shown to be suitable for research with college student populations.

A preliminary comparison of flat affect schizophrenics and brain-damaged patients on measures of affective processing.

Flat affect is a major component of schizophrenia and is often also seen in neurological disorders. A preliminary set of comparisons were conducted to delineate neuropsychological mechanisms underlying flat affect in schizophrenia, and new measures are described for the assessment of affective deficits in clinical populations. Subjects were schizophrenic with flat affect (SZs), right brain-damaged (RBD), Parkinson's Disease (PDs), and normal control (NC) right-handed adults. Subjects were administered affective measures of expression and perception in both facial and vocal channels. For both perceptual and expressive tasks the SZs performed significantly less accurately than the NCs and the PDs but did not differ from the RBDs. This was the case for both face and voice. This finding lends support to the speculation that right hemisphere mechanisms, especially cortical ones, may be compromised among schizophrenics with flat affect.

Affective predictors of dissociation, III: Affect balance.

The relationship between dissociative tendencies and the balance of affective expression was investigated in a sample of 100 Australian psychology students. Dissociation was positively related to an imbalance of affect in favor of negative affects. Higher levels of dissociation were associated with more frequent experiences of negative affects but were unrelated to the expression of positive affects. The data are consistent with the view that trauma-related affects have a mediating role in the development of dissociative tendencies.

Sensory and affective predictors of overall pain and emotions associated with affective pain.

OBJECTIVE: Psychological scaling techniques consistently produce separate ratings for sensory and affective components of pain. This study examines the relative contributions of these components to pain as a whole and the contributions of different emotions to the affective component of pain. DESIGN: The design was correlational. Visual analogue scales were used to quantify overall pain, sensory pain, affective pain, and individual emotions. These data lent themselves to regression techniques for expressing pain as a function of sensation and affect as a function of emotion types. SETTING: Data were collected at the Pain Clinic within the Department of Physical Medicine at the Ohio State University. PATIENTS: Subjects were 40 chronic pain sufferers admitted to an inpatient pain management program. RESULTS AND CONCLUSIONS: Ratings of overall pain were not a simple summation of sensory and affective ratings, but a linearly additive function of both component ratings each with a unique weighting. The affective component of pain was a function of three differentially weighted sets of emotions, anger, fear, and sadness being most salient. Implications arise for the broader assessment of chronic pain and the treatment of specific emotions that may be particularly associated with the pain.

Parental sensitivity, infant affect, and affect regulation: predictors of later attachment.

This longitudinal study on 94 families examined the extent to which parent sensitivity, infant affect, and affect regulation at 4 months predicted mother-infant and father-infant attachment classifications at 1 year. Parent sensitivity was rated from face-to-face interaction episodes; infant affect and regulatory behaviors were rated from mother-infant and father-infant still-face episodes at 4 months. Infants' attachment to mothers and fathers was rated from the Strange Situation at 12 and 13 months. MANOVAs indicated that 4-month parent and infant factors were associated with infant-mother but not infant-father attachment groups. Discriminant Function Analysis further indicated that two functions, "Affect Regulation" and "Maternal Sensitivity," discriminated infant-mother attachment groups; As and B1-B2s showed more affect regulation toward mothers and fathers than B3-B4s and Cs at 4 months, and mothers of both secure groups were more sensitive than mothers of Cs. Finally, the association between maternal sensitivity and infant-mother attachment was partially mediated by infant affect regulation.

On the broad applicability of the affective circumplex: representations of affective knowledge among schizophrenia patients.

Studies of affective experience are guided by the assumption that the structure of affect generalizes across people. Yet this assumption has not been tested among educationally and economically diverse community residents or among individuals with psychopathology. This study explicitly examined the broad applicability of the valence-arousal circumplex and whether schizophrenia patients and nonpatients have comparable knowledge structures of affective phenomena. Patients and nonpatients completed similarity ratings of 120 pairs of affect words. Similarity judgments were analyzed separately for each group using a multidimensional scaling procedure, and solutions were compared. Results revealed the same two-dimensional valence-arousal solution for schizophrenia patients and nonpatients, although there were subtle differences between the groups. These findings provide additional evidence that the circumplex model is a useful formalism for representing affective phenomena across diverse populations, and they bolster confidence in existing interpretations of schizophrenia patients' reports of affective experience.

Affect traits in differential diagnosis of anxiety, depressive, and schizophrenic disorders using the Multiple Affect Adjective Check List-Revised.

A study of 185 psychiatric patients with anxiety, mood, and schizophrenic disorders and 185 matched nonpatient controls investigated the effectiveness of the affect trait scales of the revised Multiple Affect Adjective Check List (MAACL-R) in differentiating the three disorders. Univariate and multivariate analyses supported the usefulness of the affect in global and specific diagnostic classifications. The strongest discriminant function described a general dysphoria dimension (Depression plus Anxiety minus Positive Affect) which differentiated the anxiety and mood disorder groups from schizophrenic patients and nonpatient controls. A second discriminant function best differentiated the anxiety from mood disorder groups and was defined by relatively higher anxiety and normal sensation seeking scores among anxiety disorders and relatively higher depression and lower sensation seeking among mood disorders. Schizophrenic disorders could not be reliably distinguished from the other groups by negative affect scales, although they scored lower on positive affect than normals. It was concluded that the MAACL-R was valid in making both global and specific diagnostic classifications.

Heart diseases affecting the liver and liver diseases affecting the heart.

BACKGROUND: The association of cardiac and liver disorders has not been extensively outlined in the literature. METHODS: A survey of the MEDLINE database was performed to assess the current status of research regarding the association between cardiac and liver disorders. RESULTS: Combined cardiac and hepatic disorders occur in 3 different settings: heart diseases affecting the liver, liver diseases affecting the heart, and cardiac and hepatic disorders with joint etiology. The spectrum of heart diseases affecting the liver includes mild alterations of liver function tests in heart failure, cardiogenic ischemic hepatitis, congestive liver fibrosis, and cardiac cirrhosis. The liver diseases affecting the heart include complications of cirrhosis such as hepatopulmonary syndrome, portopulmonary hypertension, pericardial effusion, and cirrhotic cardiomyopathy as well as noncirrhotic cardiac disorders such as high-output failure caused by intrahepatic arteriovenous fistulae. Cardiac and hepatic disorders with joint etiology include infectious, metabolic, immune, vasculitic, and toxic disorders. We propose a practical approach to a diagnostic workup of combined cardiac and hepatic disorders based on recognizing the sequence of appearance of the cardiac and liver disease, presence of features of a multisystem disease, and presence of pathognomonic features. The evaluation of combined cardiac and hepatic disorders takes into consideration the expected benefit of treatment and the risks related to invasive procedures. Accordingly, investigations can be limited to ancillary tests for patients with congested liver and mild alterations of liver function tests, in cardiogenic ischemic hepatitis, patients with cardiac cirrhosis who are proposed for conservative treatment, and multisystem disease involving the heart and the liver. Conversely, comprehensive investigations are recommended when invasive therapeutic interventions are considered for the treatment of hepatopulmonary syndrome, portopulmonary hypertension, or arteriovenous fistulae. CONCLUSION: Classification of a patient to any of the 3 categories-heart diseases affecting the liver, liver diseases affecting the heart, and cardiac and hepatic disorders with joint etiology-permits the physician to narrow the span of the possible diagnoses and allows for a more simple workup.

Dehabilitation of leprosy-affected people--a study on leprosy-affected beggars.

Leprosy is one of the most socially stigmatized diseases known today. Social stigma is associated mainly due to the prevalent myths like its hereditary and contagious nature, divine curse along with the physical deformities caused. The affected people not only face physical impairments but also suffer psychosocial repercussions due to the community's attitude. The long-term physical and psychosocial restrictions slowly push the leprosy-affected person out of the society. With lack of social support and self-confidence, some dehabilitated leprosy-affected persons end up as beggars. The present study focuses on the long-term consequences of leprosy. It is based on case studies of leprosy-affected beggars in Delhi. The process of dehabilitation in each case has been studied. It has been found that dehabilitation is a continuous process. The combination of leprosy, physical impairments and social stigma causing further participation restriction, lead to dehabilitation of people affected by leprosy, and ending in a state of beggary for some. There is a need to develop a holistic approach including both prevention of dehabilitation and rehabilitation of those dehabilitated to overcome both the disease and its consequences. Measures to prevent such dehabilitation in future along with the rehabilitation of leprosy-affected beggars have been suggested. Both these measures should take place simultaneously.

Cerebral processing of nonverbal affective stimuli: differential effects of cognitive and affective sets on hemispheric asymmetry.

The cerebral processing of emotion has been the subject of a number of recent studies, but results relating to hemispheric asymmetry have been quite mixed. The present study attempted to clarify and extend findings in this area by examining the differential effects of cognitive and affective sets on hemisphere asymmetry under conditions of nonverbal emotional stimulation. Electroencephalographic (EEG) data, recorded bilaterally, showed that differential hemispheric processing interacted with emotion (positive or negative), condition (cognitive or affective), and sex. In those emotion/condition combinations where hemispheric asymmetry was observed, there was greater activity in the left hemisphere than in the right. In addition, positive affect produced greater asymmetry than negative, and females showed greater activity in response to positive emotional stimuli than did males. Further, affective conditions yielded higher levels of activity than did cognitive. Finally, electrodermal activity showed lateralization effects as a differential function of cognitive and affective conditions.

Morphine differentially affects the sensory and affective pain ratings in neurogenic and idiopathic forms of pain.

In a double-blind, placebo controlled crossover study, the effect of morphine on the affective and sensory pain ratings in different forms of chronic pain was investigated. Six patients suffering from central neurogenic pain, 8 from peripheral neurogenic pain and 6 from idiopathic pain participated in the study. Morphine (0.3 mg/kg bodyweight) and placebo (saline) were administered intravenously. Both the affective and sensory dimensions of pain sensation were assessed by means of the 101-point rating scale. From our results it appeared that morphine reduced the affective but not the sensory dimension of pain sensation in both groups of neurogenic pain patients. In the idiopathic pain group, neither the affective nor the sensory dimension of pain sensation were affected. The observed differences in opioid responsiveness were neither the result of differences in opioid consumption nor of differences in baseline pain levels.
