Perfectionism and Eating Attitudes In Competitive Rowers: Moderating Effects of Body Mass,Weight Classification and Gender

Abstract

One purpose of the present research was to determine the relationship between perfectionism and eating attitudes among national level rowers. A second purpose was to determine if body mass, weight classification and gender moderate perfectionism-eating attitude relations. Rowers from New Zealand and Australia (W=449) completed the Positive and Negative Perfectionism Scale (PANPS; Terry-Short, Owens, Slade and Dewey, 1995), the Eating Attitude Test-40 (EAT-40; Garner and Garfinkel, 1979), and the Short Form of the Marlowe-Crowne Social Desirability Scale (MC-SDS; Reynolds, 1982). In addition, a Body Mass Index (BMI) was calculated from the height and weight measurements of each participant. Hierarchical multiple regression analyses showed that, after accounting for social desirability effects. Negative (unhealthy) Perfectionism scores were positively related to disturbed eating attitude scores, whereas Positive (healthy) Perfectionism scores were unrelated to disturbed eating attitude scores. In addition, body mass, weight classification and gender operated in a conjunctive fashion to produce a maximum moderator effect. That is, relations between Negative Perfectionism and disturbed eating attitudes were strongest for female lightweight rowers with higher BMI scores. Recommendations for future research are discussed.     

Prenatal maternal anxiety and early childhood temperament

The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.     

Perceived partner support in pregnancy predicts lower maternal and infant distress

Maternal postpartum emotional distress is quite common and can pose significant risk to mothers and infants. The current study investigated mothers' relationships with their partners during pregnancy and tested the hypotheses that perception of prenatal partner support is a significant predictor of changes in maternal emotional distress from midpregnancy to postpartum, and contributes to maternal ratings of infant distress to novelty. Using a prospective longitudinal design, 272 adult pregnant women were interviewed regarding their partner support, relationship satisfaction, and interpersonal security (attachment style and willingness to seek out support), and they completed standardized measures of prenatal symptoms of depression and anxiety (distress). At 6 to 8 weeks' postpartum, mothers reported these symptoms again and completed measures of their infants' temperament. Structural equation modeling (SEM) was used to test direct and indirect contributions of partner support, relationship satisfaction, and interpersonal security to maternal and infant postpartum distress. Mothers who perceived stronger social support from their partners midpregnancy had lower emotional distress postpartum after controlling for their distress in early pregnancy, and their infants were reported to be less distressed in response to novelty. Partner support mediated the effects of mothers' interpersonal security and relationship satisfaction on maternal and infant outcomes. A high-quality, supportive partner relationship during pregnancy may contribute to improved maternal and infant well-being postpartum, indicating a potential role for partner relationships in mental health interventions, with possible benefits for infants as well.     

Classroom applications of self-determined reinforcement

Self-determined, experimenter-determined, and chance-determined token reinforcement treatments were compared with a no-token treatment, in terms of effect on the learning of history and geography material in the classroom. Each treatment was assigned to one of four heterogeneous classes of Grade nine girls. An initial baseline period preceded the differential reinforcement period, and a token withdrawal period followed. Subsequently, the self-determined treatment was employed in all three token reinforcement classes, before a final baseline period occurred. Findings included a similarity of initial baseline performance for all classes, an equal superiority of self-determined and experimenter-determined treatments to chance-determined and no-token treatments, and significant improvement from initial baseline to final baseline for self-determined and experimenter-determined treatments, but not chance-determined and no-token treatments. Differential token reinforcement experience was found to influence subsequent rate of self-determined token reinforcement.     

Behavioral self-management in story writing with elementary school children

The effect of self-management procedures on objective writing responses and on the subjectively assessed quality of children's writing was investigated. All experimental procedures were applied to each of the 37 children in a regular Grade 3 class, and 14 of these children were randomly selected for data collection. Following baseline conditions, self-assessment plus self-recording of writing responses was introduced. This did not increase the number of sentences, number of different action words, or number of different describing words, or improve the quality of the stories. Self-determined and self-administered reinforcement was added to the self-assessment and self-recording procedures contingent on each of the writing responses in turn. Rates of responding were substantially increased and the stories received higher subjective ratings of quality from two independent judges. An increase in on-task behavior was correlated with self-reinforcement of writing responses.     

EFFECT OF CUEING ON SELF-CONTROL OF CLASSROOM BEHAVIOR

Behavioral self-control procedures, composed of self-assessment, self-recording, self-determination and administration of reinforcement, were introduced into a regular third-grade classroom immediately after a baseline period. The procedures produced a small and unstable increase in the level of on-task behavior in eight of the nine subjects. After a second baseline period, a cueing procedure was introduced, using a chart specifying on-task behavior. This enabled within-lesson changes in on-task behavior to be posted clearly for the children. The cueing procedure combined with the self-control procedures produced a high and stable increase in on-task behavior in all subjects.     

Racial differences in birth outcomes: the role of general, pregnancy, and racism stress.

OBJECTIVE: This study examined the role of psychosocial stress in racial differences in birth outcomes. DESIGN: Maternal health, sociodemographic factors, and 3 forms of stress (general stress, pregnancy stress, and perceived racism) were assessed prospectively in a sample of 51 African American and 73 non-Hispanic White pregnant women. MAIN OUTCOME MEASURES: The outcomes of interest were birth weight and gestational age at delivery. Only predictive models of birth weight were tested as the groups did not differ significantly in gestational age. RESULTS: Perceived racism and indicators of general stress were correlated with birth weight and tested in regression analyses. In the sample as a whole, lifetime and childhood indicators of perceived racism predicted birth weight and attenuated racial differences, independent of medical and sociodemographic control variables. Models within each race group showed that perceived racism was a significant predictor of birth weight in African Americans, but not in non-Hispanic Whites. CONCLUSIONS: These findings provide further evidence that racism may play an important role in birth outcome disparities, and they are among the first to indicate the significance of psychosocial factors that occur early in the life course for these specific health outcomes.     

Ceteris Paribus Laws and Minutis Rectis Laws

Special science generalizations admit of exceptions. Among the class of non‐exceptionless special science generalizations, I distinguish (what I will call) minutis rectis (mr) generalizations from the more familiar category of ceteris paribus (cp) generalizations. I argue that the challenges involved in showing that mr generalizations can play the law role are underappreciated, and quite different from those involved in showing that cp generalizations can do so. I outline a strategy for meeting the challenges posed by mr generalizations.     

Counseling Intimate Partner Abuse Survivors: Effective and Ineffective Interventions

This study obtained feedback from intimate partner abuse survivors (N = 104) regarding helpful and unhelpful aspects of therapy. The survivors’ narrative accounts and answers to quantitative questions were subjected to quantitative and qualitative analysis. Results suggest that survivors sought therapy to understand themselves and the abuse they endured. Clinicians’ diagnoses of codependency or assertions that survivors chose the relationship weakened the therapeutic alliance and reduced the perceived helpfulness of therapy.
