Parsing the genetic and nongenetic variance in children's depressive behavior.

Estimates of the genetic and environmental contributions to depressive behavior were derived using model-fitting analyses with data from a sample of 364 twin pairs, aged 4 to 12 years. Results suggested that genetic and nonshared environmental factors accounted for significant proportions of the variance in children's depressive symptomatology, but estimates differ for boys and girls. Further analyses indicated different genetic and environmental contributions for younger and older children. Analyses of a direct measure of shared and nonshared components of the environment identified specific aspects of children's environments which were associated with depressive behavior.

The utility of MMPI subtypes for the prediction of weight loss after bariatric surgery. Minnesota Multiphasic Personality Inventory.

In this paper we report a study designed to improve the ability to predict postoperative weight loss employing methods dictated by the premise that substantial psychological homogeneity is necessary within subsets of patients before similar weight losses can be observed within those subsets. Subjects were 138 women who completed the MMPI prior to undergoing vertical banded gastroplasty. Cluster analysis of the MMPI profiles identified 10 predictive MMPI types. Fifty-six percent of the patients were classified into the 10 types, the remainder were grouped into a residual category. Analysis of covariance revealed that MMPI type accounted for 50 percent of the variance in 12-month weight loss after covarying for initial weight and pre-operative percentage of ideal weight. Variables that added significantly to the prediction of weight loss were age and MMPI scale Pd. In general, the prototypic profiles indicative of the greatest disturbance predicted poor weight loss. In contrast to the 10 MMPI types described in this study, an alternative clustering of patients into fewer groups with much less psychological homogeneity was not predictive of outcome.

Familial aggregation of type A behavior.

This research examined the relationship of children's Type A behavior pattern, as measured by the Matthews Youth Test for Health, to parents' Type A behavior pattern, as measured by the Jenkins Activity Survey, Form C. A total of 115 families with boys and 106 families with girls enrolled in the fourth through sixth grades participated. There were no significant correlations between the Pattern A scores of fathers and those of their children, but there was evidence for a maternal influence on the development of children's Type A behavior. The results are compared with results from studies of familial aggregation previously reported in the literature.

The relations between type A behavior, clinically relevant behavior, academic achievement, and IQ in children.

The relation of Type A behavior to IQ, academic achievement, and several clinically relevant dimensions of behavior in children was assessed in 873 fourth, fifth, and sixth graders by means of the Matthews Youth Test for Health (MYTH), the Cognitive Abilities Test (CAT), the Iowa Tests of Basic Skills (ITED), and the teachers' form of the Missouri Children's Behavior Checklist (MCBC-T). The MYTH and its competitiveness and impatience-aggression subscales were found to be differentially related to academic achievement and to account for a small but significant portion of the variance in achievement not accounted for by IQ. The subscales of the MYTH were found to be highly correlated with several clinically familiar dimensions of children's behavior. The significance of these findings for the construct validity of the MYTH is discussed.

Home environment questionnaire.

Psychometric and normative data are presented for two forms of the Home Environment Questionnaire (HEQ) that provide measures of 10 variables used to describe the psychosocial environments of children. One form, HEQ-2R, is suitable for use with families in which there are two parents; the other form, HEQ-1R, is for use with one-parent families. The HEQ scales are relatively independent and not significantly related to the age of the target child, and most of the scales are reasonably internally consistent. Previous research has found several of the HEQ scales to be significantly related to several dimensions of children's clinically important behavior.

Relations between the family environment scale (FES) and the MMPI.

This study investigated the relations between FES scales and MMPI scales and the relation of social desirability and endorsement of FES items in a sample of 185 college students. FES scales were found generally not to be highly redundant with MMPI variables although MMPI Scale K (defensiveness) was significantly related to several FES scales. The social desirability and the endorsement rates of FES items were found to correlate approximately .80. Implications of these findings for the research and clinical use of the FES are discussed.

The BSRI M, F, and androgyny scores are bipolar.

Demonstrates that the Bem Sex-Role Inventory (BSRI) masculinity (M), femininity (F), and Androgyny scores reflect a bipolar dimension rather than two independent dimensions and their unique derivative. The mean endorsement of the BSRI M and F items was calculated for 50 males and 50 females separately and as a combined group. The BSRI M and F items then were scored in a bipolar fashion. A total Bipolar Androgyny score was calculated for each S by summing the S's Bipolar Androgyny scores on the M and F items. The data indicated that (1) Bem's M scores and the derived Bipolar Androgyny scores based on Bem's M items were highly correlated (congruent to .90); (2) Bem's F scores and the Bipolar Androgyny scores based on Bem's F items were highly correlated (congruent to .90); and (3) Bem's Androgyny scores and the total Bipolar Androgyny scores were highly correlated (congruent to .90). These results indicate that the BSRI Androgyny score reflects a bipolar dimension.

Further evidence that M-F is bipolar and multidimensional.

Conducted a study to identify a set of cognitive skills tests on which there are significant sex differences. The main study determined the comparability of several bipolar M-F scales and the relations between the full range of scores on each of those bipolar M-F scales and self-rated sexual orientation; 110 females and 113 males completed six cognitive tests, the Bem Sex Role Inventory (BSRI), the Minnesota Multiphasic Personality Inventory (MMPI) and the Kinsey Sexual Orientation scale (KSO). Correlations in the combined-sex group were substantially higher than in either of the single-sex groups. Each of the several M-F measures was related significantly to sexual orientation in the combined-sex group, and the combination of the MMPI Mf scale and the Bem Androgyny Score accounted for a small but significantly greater portion of the variance in self-rated sexual orientation than did the MMPI Mf scale alone. The data support the view that M-F may be considered to be a bipolar and probably multidimensional variable.

M-F: biopolar and probably multidimensional.

Scores on the MMPI MF scale and the WAIS M-F index were found not to be correlated highly with each other, but to be correlated significantly with self-rated sexual orientation in a mixed-sex group of Ss. Only when the implicit bipolarity of each of the test scales were taken into account were the scales significantly related to sexual orientation. The combination of the two M-F indices accounted for significantly more of the variance in sexual orientation than either scale alone. The results suggest that M-F may be considered accurately to be both a bipolar and a multidimensional construct.
