An Extension of the Regression of Offspring on Mid-Parent to Test for Association and Estimate Locus-Specific Heritability: The Revised ROMP Method

The Regression of Offspring on Mid-Parent (ROMP) method is a test of association between a quantitative trait and a candidate locus. ROMP estimates the trait heritability and the heritability attributable to a locus and requires genotyping the offspring only. In this study, the theory underlying ROMP was revised (ROMP_rev) and extended. Computer simulations were used to determine the type I error and power of the test of association, and the accuracy of the locus-specific heritability estimate. The ROMP_rev test had good power at the 5% significance level with properly controlled type I error. Locus-specific heritability estimates were, on average, close to simulated values. For non-zero locus-specific heritability, the proposed standard error was downwardly biased, yielding reduced coverage of 95% confidence intervals. A bootstrap approach with proper coverage is suggested as a second step for loci of interest.
ROMP_rev was applied to a study of cardiovascular-related traits to illustrate its use. An association between polymorphisms within the fibrinogen gene cluster and plasma fibrinogen was detected (p < 0.005) that accounted for 29% of the estimated fibrinogen heritability. The ROMP_rev method provides a computationally fast and simple way of testing for association and obtaining accurate estimates of locus-specific heritability while minimizing the genotyping required.     

一般人群中人格维度与心身症状的相关研究

目的：探讨在健康人群中稳定的人格特点与某一时期心身症状的测量之间的关系。方法：对721名被试施测人格量表（QZPS）和SCL-90，通过回归和相关分析探讨两者之间的关系。结果：严谨、沉稳、决断、淡泊和情绪性等人格因素与SCL-90的因子分数正相关，其它人格因素则与SCL-90的因子分数负相关。控制人格因素间的相关之后，进入每个预测心身症状回归方程的人格因素分别为3-5个,其中严谨、自制、沉稳、重感情和热情的回归系数是正值，其它为负值，表明行事严谨、自我克制以及对人热情和重感情等人格特点与心身症状的出现是一致的。结论：人格维度对心身症状有一定的预测能力。

Minnesota Multiphasic Personality Inventory (MMPI) cluster groups among chronically ill patients: Relationship to illness adjustment and treatment outcome

Cluster analysis of the MMPI has been utilized widely in the chronic low back pain literature to try to identify reliable patient subtypes predictive of treatment outcome. We extended this methodology to patients with heterogeneous chronic medical conditions by replicating prototypic MMPI cluster group profiles and by relating cluster groups to clinical baseline and outcome data. Subjects were two independent samples (n=254 and n=263) of chronically ill patients admitted to an inpatient medicine/psychiatry unit. Using a four-cluster solution, similar cluster profile groups were replicated in both samples. Consistent differences emerged between cluster groups on functional impairment, psychiatric diagnoses, depression, and psychosomatic symptoms. Cluster group membership also predicted changes in functional impairment and depression six months after treatment. Results are discussed in terms of similarities between chronic low back pain and chronic illness and tailoring treatment to different patient types.This research was supported in part by a grant from the Henry J. Kaiser Family Foundation.

MMPI, personality dysfunction and the dexamethasone suppression test in major depression

In this study we examined the relationship of psychopathology and personality dysfunction to neuroendocrine functioning. MMPI profiles were examined for 30 psychiatric inpatients with major depression who were suppressors (60%) and nonsuppressors (40%) on the dexamethasone suppression test. There were no differences between suppressors and nonsuppressors on any of the MMPI scales or on DSM-III Axis-II diagnosis. When subdivided according to T-score elevations above 70 on MMPI scales 4 and 6, or 4 and 9, 30% of the sample, however, met criteria for personality dysfunction. Furthermore, a significantly higher proportion of suppressors (50%) evidenced personality dysfunction than did the nonsuppressors (8%). This suggests that certain MMPI scales are able to identify a subgroup of depressed patients with personality disturbances who also have a hypothalamic-pituitary-adrenal dysfunction.

Personality, manual preference and neuroendocrine reactivity in hirsute subjects

Behavioral and neuroendocrine differences may be postulated in hirsute subjects since central effects of gonadal steroids are well established. We conducted a controlled clinical study with 25 consecutive young hirsute participants compared with 20 consecutive controls. Neuropsychological evaluation included the Minnesota Multiphasic Personality Inventory (MMPI) and the Edinburgh Inventory of Manual Preference (EIMP). Neuroendocrine reactivity was assessed by the adrenocorticotropic hormone (ACTH) and cortisol responses to corticotropin releasing hormone (CRH). Hirsute participants presented a flattened personality profile with lower neurotic triad scores--146 +/- 20 versus 166 +/- 28. Left-hand preference was more common in hirsute participants--4/21 versus 0/20. Decreased ACTH [area under the curve (AUC)--36 +/-2 8 vs. 72 +/- 63 pg/ml h] and cortisol (AUC--18 +/- 4 vs. 25 +/- 10 microg/dl h) responses to CRH were found in the hirsute group. In the hirsute group, higher manual preference scores were associated with lower ACTH responses to CRH, while the opposite association was found in the control group. In the hirsute group, the hyporeactive hypothalamic-pituitary-adrenal (HPA) axis was associated with lower behavior-deviant scores, while in the control group, the hyporeactive HPA axis was associated with more psychopathology. We conclude that personality and HPA axis reactivity are different in hirsute female participants when compared with controls, with a trend for differences regarding handedness. Personality and handedness are differently associated with HPA reactivity. Distinctive features in hirsute participants are probably established very early during ontogenic development.
