The MAOA gene predicts happiness in women.

Psychologists, quality of life and well-being researchers have grown increasingly interested in understanding the factors that are associated with human happiness. Although twin studies estimate that genetic factors account for 35-50% of the variance in human happiness, knowledge of specific genes is limited. However, recent advances in molecular genetics can now provide a window into neurobiological markers of human happiness. This investigation examines association between happiness and monoamine oxidase A (MAOA) genotype. Data were drawn from a longitudinal study of a population-based cohort, followed for three decades. In women, low expression of MAOA (MAOA-L) was related significantly to greater happiness (0.261 SD increase with one L-allele, 0.522 SD with two L-alleles, P=0.002) after adjusting for the potential effects of age, education, household income, marital status, employment status, mental disorder, physical health, relationship quality, religiosity, abuse history, recent negative life events and self-esteem use in linear regression models. In contrast, no such association was found in men. This new finding may help explain the gender difference on happiness and provide a link between MAOA and human happiness.

Socioeconomic background and the developmental course of schizotypal and borderline personality disorder symptoms.

Low socioeconomic status (SES) background has been identified as a risk for several mental disorders. However evidence regarding SES and the developmental course of personality disorder (PD) has not been addressed. Nor is it clear whether an SES relationship to PD symptom course may be attributable to known associated risks. Further, specificity of such relationships to a particular PD diagnostic pattern independent of comorbidity with other PD or with depression has not been investigated. Data are from a general population studied longitudinally between ages 10 and 36 in four assessment waves. Effects of SES-associated risks on the level of symptoms of schizotypal and borderline disorders are estimated and compared to effects on depressive symptoms. Low family SES had robust modest independent effects on both PDs over the entire age span despite substantial cumulative effects of trauma history, stressful recent life events, IQ, poor parenting, and comorbid symptoms. SES effects on depressive symptoms were generally absent, but a small "protective" effect of low SES appeared when comorbidity with PD symptoms was taken into account. Cumulatively, these risks account for developmental failures of substantial magnitude and consequence, marking the importance of understanding the remaining mechanisms of SES effects and programmatic implications for minimizing associated risk.

Personality disorders in early adolescence and the development of later substance use disorders in the general population.

Assessments of personality disorder (PD) and conduct disorder (CD) in a random community sample at mean age 13 were employed to predict subsequent substance abuse disorder (SUD), trajectories of symptoms of abuse or dependence on alcohol, marijuana, or other illicit substances, and hazard of initiating marijuana use over the subsequent decade. Personality disorders and conduct disorder were associated with diagnoses and symptoms of SUDs in every model and their effects were independent of correlated family risks, participant sex, and other Axis I disorders. Specific elevated PD symptoms in early adolescence were also associated with differential trajectories of already initiated SUD symptoms as well as elevated risk for future onset of SUD symptoms. For several models the greatest of these effects were shown for borderline PD and for conduct disorder, the predecessor of adult antisocial PD. Passive-aggressive PD also showed independent elevation effects on substance use symptoms for alcohol and marijuana. Analyses over 30 years suggest that Cluster B PD (borderline, histrionic, narcissistic) are independent risks for development of SUD and warrant clinical attention.

Current affairs and the public psyche: American anxiety in the post 9/11 world.

BACKGROUND: The most recent wave of interviews in a longitudinal study spanned the terrorist attacks of September 11, 2001. This unintended "natural experiment" allows examination of effects of traumatic events in ways impossible in studies conducted solely after the event and in populations not previously studied. METHODS: Participants were 610 members of the randomly selected Children in the Community cohort studied longitudinally for over 25 years and between ages 27 and 38 at the time of the current in-home interviews. Symptoms of generalized anxiety, post-traumatic stress disorder, panic disorder, agoraphobia, dissociation, and depression were assessed with an adaptation of the Structured Clinical Interview for Diagnosis. Changes in self-reported symptoms from an assessment 10 years earlier were related to the date of interview between 7/2001 and 12/2003 by polynomial regression methods, including demographic and design controls. Diagnoses based on clinical follow-up were also examined. RESULTS: In contrast to other data on this cohort where timing effects were absent, levels of symptoms were related to time of interview. The months following 9/11/2001 and the two anniversary periods in 2002 and 2003 showed significant elevation in anxiety symptoms (t = 2.50, df = 608, P = 0.013) with some evidence of elevated anxiety disorder as well (Fisher's exact test P = 0.096). Similar patterns were seen for specific anxiety and depressive symptom groups. Effects of religious participation, patriotism, having offspring, and media exposure on anxiety symptoms tended to differ by season, but the effect of community involvement did not. Proximity to New York City was not significantly related to symptoms. CONCLUSIONS: Study findings suggest that young Americans showed symptomatic and, possibly, diagnostic anxiety reactions to the events of 9/11 that persisted in response to heightened awareness of ongoing threat during anniversary periods.

Impact of adolescent mental disorders and physical illnesses on quality of life 17 years later.

OBJECTIVE: To investigate associations of mental disorders and physical illnesses during adolescence with quality of life (QOL) 17 years later. DESIGN: The Children in the Community Study, a prospective longitudinal investigation. SETTING: Upstate New York. PARTICIPANTS: A community-based sample of mothers and their offspring were interviewed. MAIN OUTCOME MEASURES: Axis I disorders and Axis II personality disorders and physical illnesses were assessed by self-report and mother report in 1985-1986. Outcome indicators of QOL were assessed in 2001-2004. RESULTS: Compared with participants without adolescent illness or disorder, those with a history of physical illness reported poorer physical health (mean difference [MD], -4.8); those with a history of an Axis I disorder reported poorer physical health (MD, -8.0) and more problematic social relationships (MD, -4.5); and those with a history of personality disorder reported poorer physical health (MD, -8.2), more problematic social relationships (MD, -5.0), lower psychological well-being (MD, -3.6), and more adversity within their environmental context (MD, -4.6) in adulthood. Comorbid physical illness and mental disorder were associated with all 5 QOL domains (MD, -3.1 to -11.9). After adjusting for all demographic variables and comorbidity, associations remained between physical illness and poor physical health (effect size [ES], -0.33); an Axis I disorder and problematic social relationships (ES, -0.37); and personality disorder and problematic social relationships (ES, -0.36), low psychological well-being (ES, -0.23), impaired role function (ES, -0.24), and an adverse environmental context (ES, -0.50). CONCLUSIONS: Mental disorders may have more adverse long-term associations with QOL than do physical illnesses. Adolescent personality disorders may have a more adverse impact on adult QOL than do adolescent Axis I disorders.

Self-reported personality disorder in the children in the community sample: convergent and prospective validity in late adolescence and adulthood.

Approximately 800 youths from the Children in the Community Study (Cohen & Cohen, 1996) have been assessed prospectively for over 20 years to study personality disorders (PDs) in adolescents and young adults. In this article we evaluate the Children in the Community Self-Report (CIC-SR) Scales, which were designed to assess DSM-IV PDs using self-reported prospective data from this longitudinal sample. To evaluate convergent validity, we assessed concordance between the CIC-SR Scales and the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II; First, Gibbon, Spitzer, Williams, & Benjamin, 1995) in 644 participants at mean age 33. To assess predictive validity, we used CIC-SR Scales at mean age 22 to predict subsequent CIC-SR and SCID-II Personality Questionnaire scores at mean age 33. In these analyses the CIC-SR Scales matched or exceeded benchmarks established in previous comparisons between self-report instruments and structured clinical interviews. Unlike other self-report scales, the CIC-SR did not appear to overestimate diagnoses when compared with SCID-II clinical diagnoses.

Adolescent Cluster A personality disorder symptoms, role assumption in the transition to adulthood, and resolution or persistence of symptoms.

Cluster A odd or eccentric personality disorder (PD) symptoms may reflect a schizophrenia spectrum biological vulnerability in at least some persons. Consequently, this symptom pattern may have particularly negative effects on the transition from adolescent to adult roles. A general population sample of 200 young adults was assessed on Cluster A PD at mean ages 17 and 22, and subsequently provided detailed narratives about their monthly experiences and behaviors between these two ages. Adolescent Cluster A PD was related to the developmental trajectories of residential, career, financial, romantic, and family formation roles during this period, and trajectories were related to a change in symptoms over this period. Symptoms were associated with early parenthood and less advanced education, but for other developmental outcomes tended to differ for men and women. These gender differences were attributable, in part, to the differential meaning and consequences of early parenthood for men and women.

Variations in patterns of developmental transitions in the emerging adulthood period.

The assumption of adult roles has largely been examined as status changes in school attendance, leaving the parental home, and marriage. Nevertheless, levels of autonomy and individuation vary considerably within these states. This study obtained such information through narrative behavioral descriptions within financial, residential, romantic, and family formation domains covering ages 17 to 27 years. Analyses of data from 240 members of a community-based longitudinal study investigated the association of trajectories in these domains with family socioeconomic status, parental divorce, gender, and race. Findings indicated that subgroup differences were not generally attributable to educational enrollment. Both within and between domains, many individuals showed dramatic changes in the assumption of adult roles, returning to more dependent, other-determined roles for short or even extended periods.
