Relationship perceptions and persistence: do fluctuations in perceived partner commitment undermine dating relationships?

The authors propose specific temporal profiles that reflect certainty versus doubt about where a partner stands with respect to a dating relationship over time. Two multiwave longitudinal studies focused on within-participant changes in perceived partner commitment. Results from multilevel modeling indicate that individuals whose perceptions of partner commitment fluctuate over time were more likely to be in a relationship that eventually ended than were individuals whose perceptions remained relatively steady. For individuals in recently initiated relationships, the association of fluctuation in perceived partner commitment with later breakup was significant regardless of the initial level of perceived partner commitment or the trend, and for all participants, it remained significant when initial level, trend over time, and fluctuation over time of other meaningful variables were controlled.

Marginalized relationships: the impact of social disapproval on romantic relationship commitment.

Little research has examined the effects of prejudice and discrimination on people's romantic relationships. The authors explored whether belonging to a socially devalued relationship affects consequential relational phenomena. Within the framework of the Investment Model, the authors (a) tested the association between perceived relationship marginalization and relationship commitment, (b) compared investment levels of individuals involved in marginalized versus nonmarginalized relationships, and (c) explored ways in which couples may compensate for decreased investments to maintain high commitment. Consistent with hypotheses, marginalization was a significant negative predictor of commitment. Moreover, individuals in marginalized relationships invested significantly less than individuals in nonmarginalized relationships. Despite investing less, marginalized relationship partners were significantly more committed than were their nonmarginalized counterparts. Thus, marginalized partners appeared to compensate for their reduced investments, with evidence suggesting that compensation occurs via reduced perception of relationship alternatives rather than via increased perception of relationship satisfaction.

Predictive accuracy of rural physicians' stated retention plans.

CONTEXT: The retention of rural physicians is a difficult phenomenon to study because job changes--the outcome of interest--take years to unfold. One common way to study retention is to ask rural practitioners through surveys how much longer they expect to remain in their current positions and use these statements of "anticipated retention" as an expedient proxy measure of actual retention. PURPOSE: To test the predictive accuracy of rural physicians' stated retention plans and test the hypotheses that predictions are more accurate for certain physicians, such as those with more experience, more control of their work situations, and at less risk for job burnout. METHODS: A 1991 mail survey (national stratified random sample) prospectively queried rural physicians' retention plans, and a follow-up survey 5 to 6 years later determined if and when respondents (N = 405, 67.5% combined response rate) had moved. FINDINGS: Retention predictions for the entire cohort corresponded remarkably well to the group's actual retention, with the proportion remaining each year deviating by only a few percentage points from what the group collectively expected. Predictions for individuals were also moderately accurate: 4 of 5 physicians who predicted remaining at least 5 years did so; 2 of 3 who predicted remaining less than 5 years indeed left before 5 years. Predictions of job changes in less than 2 years tended to be more accurate than predictions of 2 to 5 years. Physicians' predictions were more accurate when they worked in practices they owned (greater control) and were on-call 2 or fewer times each week (lower burnout risk). Accuracy was not greater with any of 5 measures of experience. CONCLUSIONS: Rural generalist physicians are moderately accurate when reporting how much longer they will remain in their jobs, validating the use of anticipated retention in rural health workforce studies.

Associations between stress reactivity and sexual and nonsexual risk taking in young adult human males.

Release of the hormone cortisol represents a distress response to novel or stressful situations. Individual differences in such reactivity have been conceptualized as representing a relatively enduring, generalizable trait. In this study, cortisol responses to two experimentally manipulated "sexual" and "nonsexual" stressors were used to examine whether stress reactivity is related to sexual and nonsexual risk behavior in young adult males. Analyses were based on 150 males 18 to 25 years old; risk behavior was assessed in confidential, self-administered questionnaires. Analyses indicated that both stressors effectively elicited cortisol increases. Generalized reactivity, defined as a cortisol response to both stressors, was inversely associated with deviance (e.g., theft, substance use) and with two indicators of sexual risk taking (lifetime number of intercourse partners and frequency of condom use). Findings are discussed in terms of cross-situational consistency of stress responses, the utility of stress reactivity for understanding individual differences in risk taking, and the interpretive limitations imposed by study design.
