Emotional states and physical health

Positive emotional states may promote healthy perceptions, beliefs, and physical well-being itself. To explore potential mechanisms linking pleasant feelings and good health, the authors consider several lines of research, including (a) direct effects of positive affect on physiology, especially the immune system, (b) the information value of emotional experiences, (c) the psychological resources engendered by positive feeling states, (d) the ways in which mood can motivate health-relevant behaviors, and (e) the elicitation of social support. As anticipated by the Greek physician Hippocrates, positive emotions and healthy outcomes may be linked through multiple pathways.     

Health anxiety moderates the effects of distraction versus attention to pain

Little is known about the relationship between health anxiety and chronic pain. The present study explored whether individual differences in health anxiety would influence the response of chronic pain patients to physical therapy. Furthermore, the interaction of health anxiety with coping strategy usage (distraction versus attention) was studied. Participants were 81 chronic pain patients who were interviewed and completed measures of pain, anxiety and cognition following an active physiotherapy session in which they either: (1) attended to physical sensations; (2) distracted from physical sensations or (3) completed the session as usual. Health anxious, compared to non-health anxious, individuals worried more about their health and injury during the session and attended to and catastrophically misinterpreted sensations more frequently. A complex interaction between health anxiety and coping strategy emerged. Among health anxious patients, attention to sensations resulted in lower anxiety and pain than did distraction. It appears as though attention had a short-term anxiety reducing effect for health anxious patients. Among non-health anxious patients, attention resulted in greater worry about health than distraction. Clinical and theoretical implications are discussed.     

Cognitive processes in social anxiety: the effects of self-focus, rumination and anticipatory processing

We examined three cognitive processes hypothesized to contribute to biases in judgments about and memory for social events: self-focused attention, post-event rumination, and anticipatory processing. Socially anxious (N = 58) and nonanxious (N = 58) subjects participated in a social interaction and then completed measures of self-focused attention and anxiety-related physiological sensations and behavior. The next day, subjects completed measures that assessed frequency of post-event processing and recall of the interaction. The results indicated that selective attention to negative self-related information led to biases in social judgments and recollections and that post-event processing contributed to the recall of negative self-related information. No evidence was found for selective retrieval of negative self-related information prior to a second social interaction. The results reconcile inconsistent previous findings related to memory bias in social anxiety.     

Fantasy proneness, dissociation, and DSM-IV axis II symptomatology

Scores on the Inventory of Childhood Memories and Imaginings (S. C. Wilson & T. X. Barber, 1981) identified fantasizers and controls who were administered the Structured Interview for DSM-IV Personality (SIDP-IV; B. Pfohl, N. Blum, & M. Zimmerman, 1994) and the Dissociative Experiences Scale (DES; E. M. Bernstein & F. W. Putnam, 1986). Fantasizers had increased rates of Cluster A and B personality disorders but were equivalent to controls in Cluster C diagnoses. For both Clusters A and B, 55% of the fantasizers received clinical diagnoses. Fantasizers had significantly higher DES, DES-T (N. G. Waller, F. W. Putnam, & E. B. Carlson, 1996), and Normal Dissociative Index scores. Although nearly one half of the fantasizers' DES-T patterns were classified within the pathological dissociative taxon (N. G. Waller & C. A. Ross, 1997), none of the controls and only 10.03% of the original screening sample received this classification. Both Axis II pathology and pathological dissociation were associated with fantasy proneness.     

Effortful control in early childhood: continuity and change, antecedents, and implications for social development

The course, antecedents, and implications for social development of effortful control were examined in this comprehensive longitudinal study. Behavioral multitask batteries and parental ratings assessed effortful control at 22 and 33 months (N = 106). Effortful control functions encompassed delaying, slowing down motor activity, suppressing/initiating activity to signal, effortful attention, and lowering voice. Between 22 and 33 months, effortful control improved considerably, its coherence increased, it was stable, and it was higher for girls. Behavioral and parent-rated measures converged. Children's focused attention at 9 months, mothers' responsiveness at 22 months, and mothers' self-reported socialization level all predicted children's greater effortful control. Effortful control had implications for concurrent social development. Greater effortful control at 22 months was linked to more regulated anger, and at 33 months, to more regulated anger and joy and to stronger restraint.     

Family perception of interpersonal behavior as a predictor in eating disorders: a prospective, six-year followup study

This study assessed family perception patterns of interpersonal behavior in families with a daughter diagnosed with an eating disorder 6 years after treatment that used a prospective design. Family perception patterns of patients found to have a poor outcome at followup (n = 15) were compared with patients with a good outcome (n = 23), as well as a control group (n = 36). Using the system of multiple level observation of groups (SYMLOG), all 238 family members evaluated themselves and each other. The index patients with a poor outcome perceived themselves as friendlier and more positive than they were perceived by their families. In comparison to parents of daughters with a good outcome and the control group, parents of daughters in the poor outcome group perceived themselves to be less friendly than their partners perceived them to be. A rigid polarization of the perception of the index patient by family members and a discrepancy in this perception between the index patient and the rest of the family were found to be indicative of a poor prognosis. Implications for treatment based on family perception patterns of interpersonal behavior are discussed.     

Evaluating gene x psychological risk factor effects in the pathogenesis of anxiety: a new model approach

The present study evaluated the singular and interactive effects of a functional polymorphism (variation) in the serotonin transporter (5-HTT) gene and a psychological trait (anxiety sensitivity [AS], i.e., fear of arousal symptoms) in predicting subjective and physiological responses to a 35% carbon dioxide (CO2) challenge in a community sample (N = 72). Genotypes were divided into 2 groups in accord with prior research. Findings were partially supportive of the hypothesized risk model. These indicated that the Group L genotype (homozygous for the 1 allele), compared with the Group S genotype (homozygous for the s allele plus heterozygous individuals), predicted greater fearful response to the biological challenge. There was also an AS x Genotype interaction predicting heart rate variability (HRV) in response to the CO2, suggesting that high AS plus Group L status predicts decreased HRV.     

A longitudinal study of high scorers on the hypomanic personality scale

Former college students (n = 36) identified by high scores on the Hypomanic Personality Scale (HYP; Eckblad & Chapman, 1986) were compared with control participants (n = 31) at a 13-year follow-up assessment. As hypothesized, the HYP group reported more bipolar disorders and major depressive episodes than the control group. The HYP group also exceeded the control group on the severity of psychotic-like experiences, symptoms of borderline personality disorder, and rates of substance use disorders. HYP group members with elevated scores on the Impulsive-Nonconformity Scale (Chapman et al., 1984) experienced greater rates of bipolar mood disorders, poorer overall adjustment, and higher rates of arrest than the remaining HYP or control participants.
