Risk factors for spirit possession among school girls in southern Thailand.

In September 1993, at a school in the south of Thailand, an outbreak of spirit possession suddenly afflicted 32 girls aged 9-14 years. A case-control study was done to investigate factors that predispose a child to spirit possession. Psychiatric evaluation was done on 32 cases and 34 matched controls. Parents were interviewed regarding the child's psychosocial history. Results of the study were as follows. Children with spirit possession were first-born and came from small families with 1-3 children. Compared with the controls their family life was characterized by more psychosocial stressors and there were significantly higher rates of psychiatric disorders, anxious and fearful character traits, histrionic character traits and history of recurrent trance states. The history of traumatic experiences and exposure to spirit possession ceremonies were more frequent in spirit-possessed children than in the control group but the difference was not significant. This study showed that being first-born from a small family, individual vulnerability especially psychiatric disorders, problematic character traits and dissociative tendency were significant risk factors in the development of possession states in children.

The association of personality characteristics with parenting problems among alcoholic couples.

This retrospective cross-sectional study explored the associations of personality characteristics with parenting problems among 25 couples, one or both members of which were identified as alcoholics by virtue of their voluntary past completion of a residential program for alcoholics. Most of them (90%) scored lower, indicating their more problematic parental attitudes and behaviors, on all four scales of the Adult-Adolescent Parenting Inventory (AAPI: inappropriate parental expectations of children, lack empathy for children's needs, value physical punishment, and parent-child role reversal) than average "normal" nonalcoholic, nonabusive adults. Such parenting problems were found to be very highly associated with clients' personality characteristics. For example, schizoid, schizotypal, histrionic, and passive aggressive characteristics (DSM-III-R-based) along with a few other personal characteristics of the couples, accounted for nearly all (90.2%, R2 = .902) of their propensity to reverse roles with their children. Findings also suggested that the identified parenting problems among alcoholic couples are amenable to programmatic intervention: the longer couples had participated in aftercare programs offered by the treatment facility the more appropriate and empathetic was their parenting.

A unified biosocial theory of personality and its role in the development of anxiety states.

A general theory of heritable personality traits and their neurobiological basis is described. Three independent dimensions of personality are defined and related to heritable variation in patterns of response to specific types of environmental stimuli: 'novelty seeking' is due to a heritable tendency toward frequent exploratory activity and intense excitement in response to novel stimuli; 'harm avoidance' is due to a heritable tendency to respond intensely to aversive stimuli and to learn to avoid punishment, novelty, and non-reward passively; and 'reward dependence' is due to a heritable tendency to respond intensely to reward and succorance and to learn to maintain rewarded behavior. Evidence suggests that variation in each dimension is strongly correlated with activity in a specific central monoaminergic pathway: novelty seeking with low basal dopaminergic activity, harm avoidance with high serotonergic activity, and reward dependence with low basal noradrenergic activity. These neurobiological dimensions interact to give rise to integrated patterns of differential responses to punishment, reward, and novelty. The combination of high novelty seeking, high reward dependence, and low harm avoidance (histrionic personality) or the combination of high harm avoidance, low reward dependence, and low novelty seeking (obsessional personality) are each associated with information-processing patterns that lead to unreliable discrimination of safe and dangerous situations and hence to chronic anxiety. In individuals with high novelty seeking, chronic anxiety is characterized by global uneasiness or alarm without specific premonitory cues, frequent bodily pains due to low pain and sensation thresholds, low sedation threshold, and slow fatigability. In contrast, in individuals with high harm avoidance, chronic anxiety is characterized by frequent anticipatory worries based on specific cues, high pain and sedation thresholds, and easy fatigability. In response to frustrative non-reward, individuals with high reward dependence are susceptible to compensatory noradrenergic hyperactivity and hence acute or recurrent states of agitated dysphoria associated with reward-seeking behaviors such as overeating and increased sexual activity. Specific predictions are made about normal personality development as well as the development and familial aggregation of anxiety, somatoform, depressive and personality disorders. These predictions are compared with available information, and recommendations are made for future research.

Age and sex distribution of DSM-III personality cluster traits in a community population.

DSM-III pathological personality cluster traits were measured on a community sample of 235 people. Traits in the schizoid cluster (schizoid, schizotypal, and paranoid) showed no change with age while traits in the dramatic cluster (antisocial, narcissistic, borderline, and histrionic) and to some extent the anxious cluster (avoidant, dependent, compulsive, and passive/aggressive) showed similar significant associations with age. This pattern was a reverse "J" shaped curve, with mean number of traits declining from younger to older groups and a slight upturn in the oldest age group (60 years plus). Women aged 31 to 40 years had a higher mean number of traits than their male counterparts, with a corresponding increase in impairment. The highest levels of personality traits in men were found at ages 18 to 30, while in women the 31 to 40 year group was highest.

Comorbidity in a clinical sample of substance abusers.

The sample consisted of 125 male inpatients admitted to one of two substance abuse treatment centers in Iowa. They were diagnosed by means of the Diagnostic Interview Schedule Screening Interview-Quick-DIS version, the Structural Interview for DSM-III-R Personality Disorder (PD), revised, and the Substance Abuse Reporting System. The most frequently diagnosed comorbid Axis I conditions were anxiety and mood disorders, while the most frequently observed Axis II disorders were in Cluster B, borderline PD, and antisocial PD followed by Cluster C, avoidant PD, passive-aggressive PD and obsessive-compulsive PD; and then Cluster A; schizoid PD. Subjects diagnosed with Borderline PD showed the highest rate of comorbid psychopathology, including Axis I disorders of generalized anxiety disorder, major depression, cocaine dependence, and inhalant dependence. The most likely comorbid diagnosis for antisocial PD subjects was bipolar disorder. The schizoid PD and the NoPD groups were less likely to meet criteria for other Axis I disorders. A high rate of comorbid Axis II pathology was also found. Polysubstance dependent subjects were more likely to be diagnosed with anxiety disorder or bipolar disorder than were those who were not polysubstance dependent or were dependent only on alcohol. Polysubstance dependent men were at highest risk for Axis II disorders: 56% of them met criteria for a Cluster B PD, with borderline PD and histrionic PD most frequent.

Derivation and implications of MMPI cluster groups in clinically depressed inpatient females.

The purpose of this study was to subclassify clinically depressed patients based on a cluster-analytic examination of the MMPI. Subjects were 79 female inpatients with major depression. A cluster analysis of the MMPI validity and clinical scales resulted in three clusters labeled psychotic (287 MMPI profile), hostile (24 MMPI profile), and histrionic (32 MMPI profile) depression. The psychotic group exhibited the greatest depression as measured by the Beck Depression Inventory (BDI). The psychotic and hostile groups, however, did not differ on other associated aspects of depression, such as negative cognitions, nonassertiveness, or personality style. The hostile group reported the fewest physical difficulties and the most excessive alcohol use. The groups, however, did not differ on other aspects of depression history or presentation such as family history of depression or previous hospitalizations. A repeated measures ANOVA for the three cluster groups on the BDI at admission, discharge, and 6 months after discharge indicated that all groups showed improvement at discharge but that only the hostile depressive group continued to show improvement at the 6-month follow-up.
