Despite substantial interest in the effects of stress on pregnancy, few instruments are available to measure pregnancy-specific stressors. Moreover, research has typically focused on the distressing, negative aspects of pregnancy. This report examines the reliability and validity of the Pregnancy Experience Scale (PES), a 41-item scale that measures pregnancy-specific daily hassles and uplifts. The PES was administered to two cohorts of low risk women at 24, 30, and 36 weeks (n = 52) or 32 and 38 weeks (n = 137). Women perceived their pregnancies to be significantly more intensely and frequently uplifting than hassling. Internal scale reliability was high (a = 0.91 to 0.95). Frequency and intensity scores for hassles and uplifts were stable over time (r's = 0.56 to 0.83) and patterns of convergent and discriminant validity emerged between the PES and existing measures of general affective intensity, daily stressors, depressive symptoms, and anxiety. These results indicate that (1) failure to measure pregnancy-specific stress will underestimate the degree to which pregnant women experience distress and (2) measurement of only the negative aspects of pregnancy will overestimate distress and fail to portray the degree to which women are psychologically elevated by their pregnancies. Measurement of hassles relative to uplifts may provide the most balanced assessment of pregnancy appraisal.
The authors investigated the association between maternal psychological and fetal neurobehavioral functioning. Data were provided by 52 maternal-fetal pairs at 24, 30, and 36 weeks gestation. The relations between maternal measures and fetal heart rate, variability, and motor activity were statistically modeled. Fetuses of women who were more affectively intense, appraised their lives as more stressful, and reported more frequent pregnancy-specific hassles were more active across gestation. Fetuses of women who perceived their pregnancy to be more intensely and frequently uplifting and had positive emotional valence toward pregnancy were less active. Associations with fetal heart-rate measures were detected at 36 weeks gestation. These data provide evidence for proximal effects of maternal psychological functioning on fetal neurobehavior.
Marriage reduces risk of cardiovascular disease (CVD) but marital stress increases risk, perhaps through cardiovascular reactivity (CVR). However, previous studies have lacked controls necessary to conclude definitively that negative marital interactions evoke heightened CVR. To test the specific effects of marital stress on CVR, 114 couples engaged in positive, neutral, or negative interactions in which speaking and task involvement were controlled. Compared to positive and neutral conditions, negative discussions evoked larger increases in systolic blood pressure, heart rate, and cardiac output, and larger decreases in peripheral resistance and pre-ejection period--similarly for men and women. Hence, CVR could contribute to the effects of marital difficulties on CVD. Previous evidence of sex differences in this effect might reflect factors other than simple reactivity to negative interactions.
Prior theory and research regarding age differences in marital interaction suggest that older couples display and experience more positivity and less negativity than middle-aged couples. However, studies of overt behavior in older couples are relatively rare and have emphasized disagreement, neglecting other important contexts for older couples such as collaboration during everyday problem solving. Further, the affiliation or communion dimension of social interaction (i.e., warmth vs. hostility) is commonly assessed, but not the control or agency dimension (e.g., dominance vs. submissiveness). The present study examined affect, cognitive appraisals, and overt behavior during disagreement (i.e., discussing a current conflict) and collaboration (i.e., planning errands) in 300 middle-aged and older married couples. Older couples reported less negative affect during disagreement and rated spouses as warmer than did middle-aged couples. However, these effects were eliminated when older couples’ greater marital satisfaction was controlled. For observed behavior, older couples displayed little evidence of greater positivity and reduced negativity – especially women. During collaboration, older couples displayed a unique blend of warmth and control, suggesting a greater focus on emotional and social concerns during problem solving.
Hostility may contribute to risk for disease through psychosocial vulnerability, including the erosion of the quality of close relationships. This study examined hostility, anger, concurrent ratings of the relationship, and change in marital adjustment over 18 months in 122 married couples. Wives' and husbands' hostility and anger were related to concurrent ratings of marital adjustment and conflict. In prospective analyses, wives' but not husbands' hostility and anger were related to change in marital adjustment. In hierarchical regression and SEM models wives' anger was a unique predictor of both wives' and husbands' change in marital adjustment. The association between wives' anger and change in husbands' marital satisfaction was mediated by husbands' ratings of conflict in the marriage. These results support the role of hostility and anger in the development of psychosocial vulnerability, but also suggest an asymmetry in the effects of wives' and husbands' trait anger and hostility on marital adjustment.
Structural models of negative affectivity and social behavior can facilitate integrative study of psychosocial risk factors. Further, self-report measures of these traits might under-estimate related CHD risk.
Marital strain confers risk of cardiovascular disease (CVD), perhaps though cardiovascular reactivity (CVR) to stressful marital interactions. CVR to marital stressors may differ between middle-age and older adults, and types of marital interactions that evoke CVR may also differ across these age groups, as relationship contexts and stressors differ with age. We examined cardiovascular responses to a marital conflict discussion and collaborative problem solving in 300 middle-aged and older married couples. Marital conflict evoked greater increases in blood pressure, cardiac output and cardiac sympathetic activation than did collaboration. Older couples displayed smaller heart rate responses to conflict than did middle-aged couples, but larger blood pressure responses to collaboration–especially older men. These effects were maintained during a post-task recovery period. Women did not display greater CVR than men on any measure or in either interaction context, though they did display greater parasympathetic withdrawal. CVR to marital conflict could contribute to the association of marital strain with CVD for middle-aged and older men and women, but other age-related marital contexts (e.g., collaboration among older couples) may also contribute to this mechanism.
This study investigated the effects of spouses' global sentiments (i.e., their marital bonds) on spouses' perceptions of their partners' specific affects. Ninety-six newlywed couples participated in the study. Positive or negative sentiment override was indicated when spouse ratings of specific affects differed from the coding of objective coders. For both positive affect and low-intensity negative affect, wives' marital bond predicted their ratings of their husbands' affect. In addition, there was evidence for positive sentiment override when wives rated husbands' low-intensity negative affect. As predicted, neither husbands nor wives were influenced by sentiment override when rating their spouses' high-intensity negative affects. These results suggest that marital bond serves as a perceptual filter through which wives evaluate their husbands' behavior. Weiss (1980) theorized that reactions during marital interaction may be determined in part by a concept he called sentiment override, by which he meant a global dimension of affection or disaffec-
