Anxiety and chronic couple relationship stress moderate adrenocortical response to couple interaction in expectant parents

The study examines whether anxiety or chronic relationship stress alter the way that couple conflict affects cortisol levels for women and men during the transition to parenthood. Saliva samples, assayed for cortisol, were collected before and after couple interaction from 128 heterosexual couples expecting their first child. Confirming prior research, expectant mothers had higher cortisol levels than their spouses, and gestational age was linked to women's cortisol level. Negativity during couple interaction was associated with greater cortisol reactivity for men, but not women. Tests of moderation indicated little relation between negativity and cortisol recovery for individuals with a low level of anxiety or little history of chronic arguing with the partner. However, among individuals with elevated levels of either of these two factors, negativity was linked to less cortisol recovery for men, but more cortisol recovery for women. Consistent results were also found for the relation between low warmth in the couple interaction and both reactivity and recovery for men and women high in anxiety. Future research should examine whether pregnancy is responsible for these different gender patterns, or whether the inhibition of negativity is stressful for women with high levels of risk.     

Relation of intimate partner violence to salivary cortisol among couples expecting a first child

Despite advances in understanding the role that several physiological systems play in the occurrence of general violence, little progress has been made toward understanding biological correlates of intimate partner violence (IPV). We explored involvement of one physiological system, the hypothalamic-pituitary-adrenal (HPA) axis. Among 137 heterosexual couples expecting a first child, baseline level of HPA activity-assessed via salivary cortisol collected before a couple conflict discussion-was linked to both men's and women's violence perpetration. HPA reactivity to the conflict bout did not show an independent association with IPV. However, persisting elevation in men's, and down-regulation in women's, HPA activity during a further recovery period was linked to men's violence perpetration.     

The Multidimensional Nature of Continuance Commitment: Commitment Owing to Economic Exchanges Versus Lack of Employment Alternatives

Purpose  

The purpose of this investigation was to develop a multidimensional measure of continuance organizational commitment, specifying dimensions for continuance commitment based on the perception of beneficial economic exchanges versus the perception of low job alternatives.

Maternal and child contributions to cortisol response to emotional arousal in young children from low-income, rural communities

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.     

The parish pastor's finest hour-revisited

Conclusion In conclusion, we have presented one small way in which the local church has potential to make a genuine contribution to healing of the sick and keeping the healthy healthy. We have discussed the rationale and present and projected models of church clinics. In the days to follow, we hope to establish and describe models that will deal still more effectively with the vast deficiencies, as seen in a variety of settings, in our health-care delivery system. Considering the tremendous resources of the local parish, we feel that involvement of that institution is most appropriate and are confident that such involvement will be healthy for both the practice of medicine and the mission of the church.     

BELIEFS ABOUT THE CONSEQUENCES OF MATERNAL EMPLOYMENT FOR CHILDREN

A 24-item scale was developed to measure Beliefs about the Consequences of Maternal Employment for Children (BACMEC), including beliefs about both benefits (13 items) and costs (11 items). Studies of five samples ( n = 375) demonstrate that the total BACMEC scale and its subscales are highly reliable and have good convergent, divergent, and con-current validity. Scores on the Costs Subscale predicted greater sex-role traditionalism, women's employment status (not employed), and an older age of child at which mother's employment was deemed acceptable. Benefits scores predicted women's employment status (employed) and work hours (longer), younger age of child when maternal work is accept-able, and greater support for policies to aid working parents. The scales were not susceptible to a social desirability bias. Suggestions are provided for the use of the BACMEC scale in future research concerning employment and families.     

FIELD REPLICATION OF CLASSWIDE PEER TUTORING

We conducted a large-scale field replication study of classwide peer tutoring applied to spelling instruction (Greenwood, Delquadri, & Hall, 1984). Two hundred and eleven inner-city students in four schools participated during their first- and second-grade school years. The effects of classwide peer tutoring were compared to teacher instructional procedures and pretest probes using a group replication design (Barlow, Hayes, & Nelson, 1984). Analysis of group and individual results indicated that (a) both teacher instructional procedures and classwide peer tutoring were effective in increasing spelling performance above pretest levels, (b) peer tutoring produced statistically greater gains relative to the teachers' procedures for both low and high student groups formed on pretest levels, (c) these outcomes were representative of groups, classes, individuals, and years during the project, and (d) participant satisfaction with the program was generally high. A separate analysis of the social importance of treatment outcome revealed differential findings for low and high groups related to pretest levels. Implications of these findings are discussed.
