Problem-solving training for family caregivers of women with disabilities: A randomized clinical trial

ObjectiveTo examine the effectiveness of an individualized problem-solving intervention provided to family caregivers of women living with severe disabilities.DesignFamily caregivers were randomly assigned to an education-only control group or a problem-solving training (PST) intervention group. Participants received monthly contacts for 1 year.ParticipantsFamily caregivers (64 women, 17 men) and their care recipients (81 women with various disabilities) consented to participate.Main outcome measuresCaregivers completed the Social Problem-Solving Inventory – Revised, the Center for Epidemiological Studies Depression scale, the Satisfaction with Life scale, and a measure of health complaints at baseline and in three additional assessments throughout the year.ResultsMultilevel modeling was used to conduct intent-to-treat analyses of change trajectories for each outcome variable. Caregivers who received PST reported a significant linear decrease in depression over time; no effects were observed for caregiver health or life satisfaction. Caregivers who received PST also displayed an increase in constructive problem-solving styles over the year.ConclusionsPST may benefit community-residing family caregivers of women with disabilities, and it may be effectively provided in home-based sessions that include face-to-face visits and telephone sessions.     

Preventive intervention with infants and families: The NBAS model

A model for preventive intervention based on the use of the Neonatal Behavioral Assessment Scale (NBAS) is presented, and the conceptual framework underlying this approach is made explicit. The approach is based on the assumption that the neonatal period presents clinicians with a unique opportunity to influence parent-infant relations positively from the beginning. It is argued that especially under conditions of stress, this infant-centered but family-focused form of intervention can serve to prevent the compounding of problems that may occur when the caregiving environment is unable to adjust to the needs of the young infant. The aim of the NBAS-based approach is to sensitize parents to the communication cues and the unique adaptive capacities of their infants. It is the individualized nature of the NBAS-based approach that places it outside the domain of main-effects treatment modalities and renders it responsive to the particular needs of individual infants and their families. The model of intervention described herein is based on the development of a supportive therapeutic relationship between clinicians and parents and as such may serve as the first stage in a comprehensive follow-up program of support for infants and families. Guidelines for clinicians using the NBAS in clinical settings that follow from these assumptions are provided.     

Associations between childhood adversity and daily suppression and avoidance in response to stress in adulthood: can neurobiological sensitivity help explain this relationship?

Background and objectives: Although it has been postulated that psychological responses to stress in adulthood are grounded in childhood experiences in the family environment, evidence has been inconsistent. This study tested whether two putative measures of neurobiological sensitivity (vagal flexibility and attentional capacity) moderated the relation between women’s reported exposure to a risky childhood environment and current engagement in suppressive or avoidant coping in response to daily stress.

Design and methods: Adult women (N?=?158) recruited for a study of stress, coping, and aging reported on early adversity (EA) in their childhood family environment and completed a week-long daily diary in which they described their most stressful event of the day and indicated the degree to which they used suppression or avoidance in response to that event. In addition, women completed a visual tracking task during which heart rate variability and attentional capacity were assessed.

Results: Multilevel mixed modeling analyses revealed that greater EA predicted greater suppression and avoidance only among women with higher attentional capacity. Similarly, greater EA predicted greater use of suppression, but only among women with greater vagal flexibility.

Conclusion: Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.     

Resampling programs for multiway contingency tables with fixed marginal frequency totals

A resampling algorithm is presented for analyzing multiway contingency tables with fixed marginal frequency totals. Applications are illustrated with extensions of Fisher's exact, Pearson's chi-squared, and likelihood-ratio tests to three-way contingency tables.     

PREFERENCE FOR A STIMULUS THAT FOLLOWS A RELATIVELY AVERSIVE EVENT: CONTRAST OR DELAY REDUCTION?

Several types of contrast effects have been identified including incentive contrast, anticipatory contrast, and behavioral contrast. Clement, Feltus, Kaiser, and Zentall (2000) proposed a type of contrast that appears to be different from these others and called it within-trial contrast. In this form of contrast the relative value of a reinforcer depends on the events that occur immediately prior to the reinforcer. Reinforcers that follow relatively aversive events are preferred over those that follow less aversive events. In many cases the delay reduction hypothesis proposed by Fantino (1969) also can account for such effects. The current experiments provide a direct test of the delay reduction and contrast hypotheses by manipulating the schedule of reinforcement while holding trial duration constant. In Experiment 1, preference for fixed-interval (FI) versus differential-reinforcement-of-other-behavior (DRO) schedules of reinforcement was assessed. Some pigeons preferred one schedule over the other while others demonstrated a position (side) preference. Thus, no systematic preference was found. In Experiment 2, a simultaneous color discrimination followed the FI or DRO schedule, and following training, preference was assessed by presenting the two positive stimuli simultaneously. Consistent with the contrast hypothesis, pigeons showed a significant preference for the positive stimulus that in training had followed their less preferred schedule.     

Threatened by the unexpected: physiological responses during social interactions with expectancy-violating partners

Individuals who violate expectations increase uncertainty during social interactions. Three experiments explored whether expectancy-violating partners engender "threat" responses in perceivers. Participants interacted with confederates who violated or confirmed expectations while multiple measures were assessed, including cardiovascular reactivity, task performance, appraisals, and behavior. In Experiments 1 and 2, participants interacted with White or Latino confederates who described their family backgrounds as either high or low socioeconomic status. In Experiment 3, participants interacted with Asian or White confederates who spoke with expected accents or southern accents. Participants interacting with expectancy-violating partners (e.g., Asians with southern accents) exhibited cardiovascular responses consistent with threat, poorer task performance, and manifested negative and defeat-related behavior. Implications for decreasing prejudicial responses via uncertainty reduction are discussed.     

Social capital,acculturation attitudes,and sociocultural adaptation of migrants from central Asian republics and South Korea in Russia

This research examines the relationship of social capital with the acculturation attitudes and sociocultural adaptation of 122 migrants from Central Asian republics of the former Union of Soviet Socialist Republics (Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan, and Kazakhstan) and 136 migrants from South Korea. The questionnaire included scales for assessing acculturation attitudes (integration, assimilation, and separation), individual social capital (bridging and bonding), and sociocultural adaptation. Using parallel mediation analysis, we found that acculturation attitudes for migrants from Central Asia are secondary to their social capital in relation to sociocultural adaptation. However, among migrants from South Korea, social capital is not linked to their acculturation attitudes, and in general, its role in sociocultural adaptation is lower as compared to the role of acculturation attitudes. As a whole, our research shows that although sociocultural adaptation for all ethnic groups is linked to acculturation attitudes and social capital, acculturation attitudes for certain ethnic groups can be dependent on social capital.
