Do changes in drinking motives mediate the relation between personality change and “maturing out” of problem drinking?

Recent research has indicated that developmental changes in the personality traits of neuroticism and impulsivity correlate with changes in problem drinking during emerging and young adulthood. However, it remains unclear what potential mechanisms, or mediators, could account for these associations. Drinking motives, particularly drinking to regulate negative affect (drinking to cope) and to get “high” or “drunk” (drinking for enhancement), have been posited to mediate the relationship between personality and drinking problems. Recent work indicates that changes in drinking motives parallel changes in alcohol involvement from adolescence to young adulthood. The present study examined changes in drinking motives (i.e., coping and enhancement) as potential mediators of the relation between changes in personality (impulsivity and neuroticism) with changes in alcohol problems in emerging and young adulthood. Analyses were based on data collected from a cohort of college students (N = 489) at varying risk for alcohol use disorders from ages 18 to 35. Parallel process latent growth modeling indicated that change in coping (but not enhancement) motives specifically mediated the relation between changes in neuroticism and alcohol problems as well as the relation between changes in impulsivity and alcohol problems. Findings suggest that change in coping motives is an important mechanism in the relation between personality change and the “maturing out” of problematic alcohol involvement.

Do cardiovascular risk factors explain the relation between socioeconomic status, risk of all-cause mortality, cardiovascular mortality, and acute myocardial infarction?

Much remains to be understood about how low socioeconomic status (SES) increases cardiovascular disease and mortality risk. Data from the Kuopio Ischemic Heart Disease Risk Factor Study (1984-1993) were used to estimate the associations between acute myocardial infarction and income, all-cause mortality, and cardiovascular mortality in a population-based sample of 2,272 Finnish men, with adjustment for 23 biologic, behavioral, psychologic, and social risk factors. Compared with the highest income quintile, those in the bottom quintile had age-adjusted relative hazards of 3.14 (95% confidence interval (CI) 1.77-5.56), 2.66 (95% CI 1.25-5.66), and 4.34 (95% CI 1.95-9.66) for all-cause mortality, cardiovascular mortality, and AMI, respectively. After adjustment for risk factors, the relative hazards for the same comparisons were 1.32 (95% CI 0.70-2.49), 0.70 (95% CI 0.29-1.69), and 2.83 (95% CI 1.14-7.00). In the lowest income quintile, adjustment for risk factors reduced the excess relative risk of all-cause mortality by 85%, that of cardiovascular mortality by 118%, and that of acute myocardial infarction by 45%. These data show how the association between SES and cardiovascular mortality and all-cause mortality is mediated by known risk factor pathways, but full "explanations" for these associations will need to encompass why these biologic, behavioral, psychologic, and social risk factors are differentially distributed by SES.     

Do children endorse psychosocial factors in the transmission of illness and disgust?

The present studies examined beliefs concerning the impact of psychosocial factors in the transmission of contagious illness, injuries, and disgust. In Studies 1 and 2, participants ranging from preschoolers through adults judged the likelihood that a character would get sick (or injured) after being contaminated by another individual who was either of no stated relation to the character or who was a best friend, a disliked person, or a family member. Studies 3 and 4 examined effects of psychosocial relatedness on judgments of disgust (a psychological response). Study 5 examined the influence of germs on judgments of disgust. Overall, preschoolers through 2nd graders judged that any type of relatedness decreased the possibility of contracting illness from another person. However, for disgust, preschoolers judged that negative contagion would have a more powerful effect, particularly in the presence of germs. Relatedness had no effect on judgments of injury transmission. These results suggest that young children treat the psychological and biological domains as distinct but mutually interacting.

Self-perceived competence and the relation between life events and depressive symptoms in adolescence: Mediator or moderator?

In a 2-wave longitudinal study, 9th-grade students (N ?=?468) completed self-report measures of stressful life events, depressive symptoms, and 5 domains of self-perceived competence (i.e., academic competence, social acceptance, physical appearance, behavioral conduct, and athletic competence). Teachers and peers also reported about the participants' depressive symptoms. In longitudinal analyses, negative (but not positive) events related to depressive symptoms. Results suggested that self-perceived competence served as a mediator (but not a moderator) of this relation. Negative events predicted changes in self-perceived competence. Self-perceived competence predicted changes in depressive symptoms. Also, the direct effect of negative events on depressive symptoms diminished after controlling for self-perceived competence.

Do expectancies for reinforcement from smoking change after smoking initiation?

Expectancies are important predictors of smoking behavior. Recent research suggests that expectancies are not stable and vary across internal and external states and levels of cigarette consumption. Expectancies may also vary between individuals as a function of temperamental characteristics such as behavioral undercontrol (BU). Although pre-initiation expectancies have been linked to subsequent smoking behaviors, no study has assessed the effect of smoking initiation on expectancies. The present study was designed to test the hypotheses that both positive (PRE) and negative (NRE) reinforcement expectancies would increase following initiation, and that these changes would be moderated by BU. College students were interviewed 12–15 months apart. Those who initiated smoking between assessments (n = 69) were included in the present study. Linear mixed models showed a significant increase in PRE but not NRE from pre- to postinitiation. The relationship between NRE and time was moderated by BU, such that higher BU was associated with significantly larger post-initiation increases in NRE. Findings suggest that PRE and NRE change significantly following experience with smoking. Furthermore, undercontrolled, impulsive individuals may be particularly vulnerable to smoking with the intention of alleviating aversive states.

The relations between parents’ Big Five personality factors and parenting: A meta-analytic review.

To investigate the association between Big Five personality factors and three dimensions of parenting—warmth, behavioral control, and autonomy support—the authors conducted meta-analyses using 5,853 parent–child dyads that were included in 30 studies. Effect sizes were significant and robust across mother and father reports and across assessment methods of parenting (self-report versus observations) but were generally small in magnitude. Higher levels of Extraversion, Agreeableness, Conscientiousness, and Openness and lower levels of Neuroticism were related to more warmth and behavioral control, whereas higher levels of Agreeableness and lower levels of Neuroticism were related to more autonomy support. Several factors moderated the relationship between specific personality dimensions and parenting: child and parental age, reliability of observational assessment of parenting behavior, and study design. Taken together, these results indicate that personality can be seen as an inner resource that affects parenting. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does socioeconomic status explain the relationship between admissions tests and post-secondary academic performance?

Critics of educational admissions tests assert that tests measure nothing more than socioeconomic status (SES) and that their apparent validity in predicting academic performance is an artifact of SES. The authors examined multiple large data sets containing data on admissions and related tests, SES, and grades showing that (a) SES is related to test scores (r = .42 among the population of SAT takers), (b) test scores are predictive of academic performance, and (c) statistically controlling for SES reduces the estimated test?grade correlation from r = .47 to r = .44. Thus, the vast majority of the test?academic performance relationship was independent of SES: The authors concluded that the test?grade relationship is not an artifact of common influences of SES on both test scores and grades.

Examining the relations between rumination and adjustment: Do ethnic differences exist between Asian and European Americans?

Past studies have pointed to the dysfunctional nature of rumination in adults. However, past research has not examined ethnic variations. Accordingly, this study examined ethnic differences in rumination in 184 Asian American and 238 European American college students. Consistent with expectations, Asian Americans were found to ruminate more than European Americans. However, rumination was found to have a weaker association with measures of adjustment (viz., affectivity, depressive symptoms, anxious symptoms, and life satisfaction) in Asian Americans compared with European Americans. As a result of conducting regression analyses to determine whether rumination was a unique predictor of functioning beyond affectivity, we found rumination to be a more distinct and useful predictor of functioning for Asian Americans than for European Americans. Overall, compared with findings for European Americans, our findings indicate that important ethnic differences need to be considered in studying rumination in Asian Americans.

Do women's provider-role attitudes moderate the links between work and family?

The authors examined the links between mothers' work qualities and their individual well-being and marital quality, as well as adolescent daughters' and sons' gender-role attitudes, as a function of mothers' provider-role attitudes, in 134 dual-earner families. In home interviews, mothers described their work, provider-role attitudes, family relationships, and mental health; their offspring reported gender-role attitudes. Women's attitudes about breadwinning were coded into main-secondary, coprovider, and ambivalent coprovider groups. Mothers' provider-role attitudes moderated the links between status indicators and mothers' depression, marital conflict, and daughters' gender-role attitudes. For example, depression and marital conflict were negatively related to coprovider mothers' earnings and occupational prestige. The same was not true for main-secondary and ambivalent coprovider mothers. These findings underscore the importance of considering employed women's interpretation of their work roles when exploring work-family links.

Do neighborhood and home contexts help explain why low-income children miss opportunities to participate in activities outside of school?

In this study, children’s participation (N = 1,420) in activities outside of elementary school was examined as a function of disparities in family income using data from the Panel Study of Income Dynamics, Child Development Supplement. Children’s neighborhood and home environments were investigated as mechanisms linking income disparities and participation rates. Family income was positively associated with children’s participation in activities, with the largest effect sizes evident for children at the lowest end of the income distribution. Affluence in the neighborhood and cognitive stimulation in the home were both important mediators of the association between income and participation, explaining from approximately one tenth to one half of the estimated associations between income and participation.

Do gender differences in help avoidance vary by ethnicity? An examination of African American and European American students during early adolescence.

The present research examined whether the nature of gender differences varies by race for two types of academic engagement in the classroom (help avoidance and voice with the teacher) in a sample of early adolescents (N = 456; 55% female, 60% African American and 40% European American) making the transition to middle school. Growth curve analyses indicated that help avoidance increased over time, voice remained stable, and achievement declined. In line with hypotheses based on cultural variations in the female role, there were no gender differences in help avoidance for African American students, whereas for European American students, girls were lower in help avoidance than were boys. For African American students, there were no gender differences in voice with the teacher, whereas for European American students, girls were higher than were boys. These group differences were present at all 3 waves. For all students, increases in help avoidance negatively predicted changes in achievement, whereas increases in voice positively predicted achievement. Results underscore the importance of examining gender and ethnicity together to understand academic adjustment during early adolescence.

High-level reasoning and base-rate use: Do we need cue-competition to explain the inverse base-rate effect?

Previous accounts of the inverse base-rate effect (D. L. Medin & S. M. Edelson, see record 1988-31640-001) have revolved around the concept of cue-competition. In this article, the authors propose that high-level reasoning in the form of an eliminative inference mechanism may contribute to the effect. A quantitative implementation of this idea demonstrates that it has the power by itself to produce the pattern of base-rate effects in the Medin and Edelson (1988) design. Four predictions are derived that contradict the predictions by attention to distinctive input (ADIT; J. K. Kruschke, see record 1996-02680-001), up to date the most successful account of the inverse base-rate effect. Results from 3 experiments disconfirm the predictions by ADIT and demonstrate the importance of high-level reasoning in designs of the Medin and Edelson kind. Implications for the interpretation of the inverse base-rate effect and the attention-shifting mechanisms presumed by ADIT are discussed.

Are anxiety and depression just as stable as personality during late adolescence? Results from a three-year longitudinal latent variable study.

Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression. Comparison of various representations of a latent variable trait-state-occasion (TSO) model revealed that whereas the full TSO model was the best representation for depression, a trait stability model was the most parsimonious of the best-fitting models for the anxiety and personality constructs. Over three years, the percentages of variance explained by the trait component for the anxiety and personality constructs (73–84%) were significantly greater than that explained by the trait component for depression (46%). These findings indicate that symptoms of depression are more episodic in nature, whereas symptoms of anxiety are more similar to personality variables in their expression of stability.

Do resisted temptations during smoking cessation deplete or augment self-control resources?

A resource depletion model of self-control posits that for some period following performance of a task requiring self-control, self-control will be reduced and thus less available for use in a subsequent task. Using 2 substantial data sets collected in real time from individuals who were trying to quit smoking (1,660 and 9,516 temptation episodes collected from 61 and 248 individuals, respectively), we evaluated this model by testing the hypotheses that the number and length of resisted temptations and the intensity of the most recently reported urge during the prior 4 hr predict decreased self-control and increased likelihood of lapsing. Survival and multilevel regression modeling showed that contrary to the hypothesis, the number of recently resisted temptations predicted a lower risk of lapsing in both samples. Duration of resisted temptations had no significant effect in either sample. Intensity of most recently reported urge predicted lapsing in 1 data set but not in the other. Overall, there was little support for the resource depletion model. The protective effect of successfully resisting temptations was an unexpected but provocative finding.

Do sodium nitroprusside and L-NAME affect pyrogen fever in rabbits?

Thermoregulatory responses after treatment with nitric oxide (NO) donor, sodium nitroprusside (SNP-3 mg/kg/h), or NO synthase inhibitor, NG-nitro-L-arginine methylester (L-NAME-100 mg/kg) were investigated in febrile rabbits (lipopolysaccharide E. coli-1 meg/kg). Pretreatment with SNP attenuated pyrogen fever as well as metabolic rate. L-NAME also inhibited postpyrogen increases in metabolism; however, this effect did not lead to antipyresis.     

Do neurocognitive ability and personality traits account for different aspects of psychosocial outcome after traumatic brain injury?

Objective: To examine the contributions of demographic, injury, cognitive, and personality characteristics to psychosocial outcome 8 years after traumatic brain injury (TBI). Design: Multiple regression analyses were used to estimate the variance explained by putative "predictors" of psychosocial outcome. Participants: Thirty-nine TBI survivors and 39 family member informants. On the basis of Glasgow Coma Scale scores and Accident Injury Severity (head) ratings, the patients' brain injuries ranged from mild to critical in severity. Main Outcome Measures: One self-report measure combined putative markers of social role engagement, such as marital status and earned income. Another, based on informant ratings using the Katz Adjustment Scale, was conceptualized as reflecting behavioral adjustment. Results: Whereas cognitive functioning explained significant unique variation in social role engagement, it did not account for variance in behavioral adjustment. Conversely, whereas 3 personality trait ratings explained significant incremental variance in behavioral stability, only 1 did the same with respect to social role engagement. Conclusions: Social role engagement and behavioral adjustment appear to represent 2 related but distinguishable aspects of TBI outcome that are associated with different patient characteristics.

Females’ quality of relationships in adolescence and friendship support in adulthood.

Thirty-one couples and their daughters participated in a study of the contribution of family and friendship relationships in adolescence, and of daughter/friend communication in adulthood to the adult daughters’ perception of friendship support in adulthood. Questionnaires and direct observation of communication skills were used to evaluate marital quality, parental quality, and friendship quality at Time 1 (T1). At Time 2 (T2), 7 years later, daughters and their best friends completed questionnaires and videotaped social support interactions. A hierarchical regression model was used to predict daughters’ perception of friendship support in adulthood. The findings indicated that higher levels of T1 mother/father marital satisfaction, higher levels of T1 mother/daughter positive communication, lower levels of T1 mother/daughter negative communication, and higher levels of T2 daughters’ validation during communication with best friend uniquely predicted higher levels of T2 daughters’ perception of friendship support. The findings suggest that family relationship quality in adolescence contributes to children’s ability to develop and maintain adaptive resources for coping with stress in adulthood.

Can the neurotrophic hypothesis explain degeneration and loss of plasticity in mature and ageing autonomic nerves?

The development of Ca-ATPase immunoreactivity in gerbil outer hair cells (OHCs), assayed by immunofluorescence and postembedding immunocytochemistry, is reported here. In the adult, a linear array of label is seen inside the lateral plasma membrane. The ultrastructural distribution of Ca-ATPase near the OHC lateral plasma membrane was examined using immunogold cytochemistry and showed this calcium pumping enzyme to be present throughout the subsurface cisternal complex (SSC), especially near the innermost layers. During development, Ca-ATPase immunoreactivity appeared in patches near the lateral plasma membrane of some OHCs of the third row by 12 days after birth (DAB). By 15-16 DAB, punctate immunoreactivity was detected in the second and first rows. At 20 DAB, immunostaining near OHC lateral plasma membrane was increased, but was less continuous than OHC staining in the adult cochlea. The appearance of Ca-ATPase in OHCs coincides with the onset of auditory function and isolated OHC motility in the gerbil. The ultrastructural demonstration of abundant sites of calcium pumps in the SSC supports a role for this structure in the intracellular storage of calcium. These findings suggest a possible role of Ca-ATPase and the SSC in the regulation of slow motility of OHCs which has been reported to depend on intracellular calcium concentration.     

Who attains social status? Effects of personality and physical attractiveness in social groups.

One of the most important goals and outcomes of social life is to attain status in the groups to which we belong. Such face-to-face status is defined by the amount of respect, influence, and prominence each member enjoys in the eyes of the others. Three studies investigated personological determinants of status in social groups (fraternity, sorority, and dormitory), relating the Big Five personality traits and physical attractiveness to peer ratings of status. High Extraversion substantially predicted elevated status for both sexes. High Neuroticism, incompatible with male gender norms, predicted lower status in men. None of the other Big Five traits predicted status. These effects were independent of attractiveness, which predicted higher status only in men. Contrary to previous claims, women's status ordering was just as stable as men's but emerged later. Discussion focuses on personological pathways to attaining status and on potential mediators.
