The extent to which the mother–child interactive relationship either promotes or limits a child's ability to see options or choices in the environment was investigated. It was predicted that this quality of interaction provided primarily by the mother would relate to the child's cognitive development as reflected in his or her level of symbolic play. The level and frequency of symbolic and nonsymbolic play in 30 children, ages 12 to 47 months, were coded and mothers' options‐promoting and options‐limiting behaviors were identified. Children, across this range of ages, whose mothers created an options‐promoting social context were observed engaging in more symbolic play. Nonsymbolic play, however, was not found to be significantly influenced by the mother's interactive style. A child's symbolic play marks a dynamic developmental achievement for the child, and appears to be related to the social context created by the mother's interactive style. ©2003 Michigan Association for Infant Mental Health.  相似文献

The current study examined the individual and joint effects of self‐reported adult attachment style, psychological distress, and parenting stress on maternal caregiving behaviors at 6 and 12 months of child age. We proposed a diathesis‐stress model to examine the potential deleterious effects of stress for mothers with insecure adult attachment styles. Data from 137 mothers were gathered by the longitudinal Durham Child Health and Development Study. Mothers provided self‐reports using C. Hazan and P. Shaver's ( 1987 ) Adult Attachment Style measure, the Brief Symptom Inventory (L.R. Derogatis & P.M. Spencer, 1982 ), and the Parent Stress Inventory (R.R. Abidin, 1995 ); observations of parenting data were made from 10‐min free‐play interactions. Consistently avoidant mothers were less sensitive with their infants than were consistently secure mothers; however, this effect was limited to avoidant mothers who experienced elevated levels of psychological distress. Results suggest that the association between insecure adult attachment style and insensitive parenting behavior is moderated by concurrent psychosocial stress. Clinical implications for these findings are discussed.  相似文献

Significant discrepancies have been found between interview- and questionnaire-based assessments of psychopathology; however, these studies have typically compared instruments with unmatched item content. The Eating Disorder Examination (EDE), a structured interview, and the questionnaire version of the EDE (EDE-Q) are considered the preeminent assessments of eating disorder symptoms and provide a unique opportunity to examine the concordance of interview- and questionnaire-based instruments with matched item content. The convergence of EDE and EDE-Q scores has been examined previously; however, past studies have been limited by small sample sizes and have not compared the convergence of scores across diagnostic groups. A meta-analysis of 16 studies was conducted to compare the convergence of EDE and EDE-Q scores across studies and diagnostic groups. With regard to the EDE and EDE-Q subscale scores, the overall correlation coefficient effect sizes ranged from .68 to .76. The overall Cohen's d effect sizes ranged from .31 to .62, with participants consistently scoring higher on the questionnaire. For the items measuring behavior frequency, the overall correlation coefficient effect sizes ranged from .37 to .55 for binge eating and .90 to .92 for compensatory behaviors. The overall Cohen's d effect sizes ranged from -0.16 to -0.22, with participants reporting more binge eating on the interview than in the questionnaire in 70% of the studies. These results suggest the interview and questionnaire assess similar constructs but should not be used interchangeably. Additional research is needed to examine the inconsistencies between binge frequency scores on the 2 instruments.  相似文献

Dominance‐based ordinal multiple regression (DOR) is designed to answer ordinal questions about relationships among ordinal variables. Only one parameter per predictor is estimated, and the number of parameters is constant for any number of outcome levels. The majority of existing simulation evaluations of DOR use predictors that are continuous or ordinal with many categories, so the performance of the method is not well understood for ordinal variables with few categories. This research evaluates DOR in simulations using three‐category ordinal variables for the outcome and predictors, with a comparison to the cumulative logits proportional odds model (POC). Although ordinary least squares (OLS) regression is inapplicable for theoretical reasons, it was also included in the simulations because of its popularity in the social sciences. Most simulation outcomes indicated that DOR performs well for variables with few categories, and is preferable to the POC for smaller samples and when the proportional odds assumption is violated. Nevertheless, confidence interval coverage for DOR was not flawless and possibilities for improvement are suggested.  相似文献

Dementia caregiving is associated with elevations in depressive symptoms and increased risk for cardiovascular diseases (CVD). This study evaluated the efficacy of the Pleasant Events Program (PEP), a 6-week Behavioral Activation intervention designed to reduce CVD risk and depressive symptoms in caregivers. One hundred dementia family caregivers were randomized to either the 6-week PEP intervention (N = 49) or a time-equivalent Information-Support (IS) control condition (N = 51). Assessments were completed pre- and post-intervention and at 1-year follow-up. Biological assessments included CVD risk markers Interleukin-6 (IL-6) and D-dimer. Psychosocial outcomes included depressive symptoms, positive affect, and negative affect. Participants receiving the PEP intervention had significantly greater reductions in IL-6 (p = .040), depressive symptoms (p = .039), and negative affect (p = .021) from pre- to post-treatment. For IL-6, clinically significant improvement was observed in 20.0% of PEP participants and 6.5% of IS participants. For depressive symptoms, clinically significant improvement was found for 32.7% of PEP vs 11.8% of IS participants. Group differences in change from baseline to 1-year follow-up were non-significant for all outcomes. The PEP program decreased depression and improved a measure of physiological health in older dementia caregivers. Future research should examine the efficacy of PEP for improving other CVD biomarkers and seek to sustain the intervention's effects.  相似文献

The military environment has unique stressors. This study investigates the types of stressors, appraisals, and coping responses of U.S. soldiers and their leaders. A qualitative analysis of interviews indicates that the traditional coping buffers of social drinking and seeking social support from fellow soldiers, family, and leaders can potentially serve as sources of stress. While this paradox may be a result of the unique types of stressors in the military work environment, these results should direct researchers to better understand individuals' perceptions and appraisals of stress, with a focus on the meaning of stress, given contextual factors inherent in the workplace. The findings are discussed in relation to the literature on the impact of stress on physical and psychological health.  相似文献

This article summarizes the development and validation of the Adult Attachment Projective System (AAP), a measure we developed from the Bowlby–Ainsworth developmental tradition to assess adult attachment status. The AAP has demonstrated excellent concurrent validity with the Adult Attachment Interview (George, Kaplan, &; Main, 1984/1985/1996 Finn, S. E. 2007.

The AAP coding and classification system and application in clinical and community samples are summarized. Finally, we introduce the 3 other articles that are part of this Special Section and discuss the use of the AAP in therapeutic assessment and treatment.  相似文献

Rotter's (1966) I–E Locus of Control Scale was administered to 18 men in residential treatment for alcoholism and 13 men in intensive outpatient treatment for obesity. The obese sample scored significantly higher in internal locus of control, whereas the alcoholic sample was comparatively external in control orientation. These findings contradict currently held assumptions on the directionality of control orientation among both alcoholic and obese adults and suggest that internally oriented obese adults may feel that they have little control over their weight and eating behavior but more control over other aspects of their lives. In contrast, externally oriented alcoholics appear to be aware of their inability to control their drinking and their limited control over many factors influencing their lives. Implications for treatment are also discussed.  相似文献

Study 1 examined the perceived association of AIDS and death by showing that thinking about AIDS increased participants'; death-thought accessibility. Hypotheses about the consequences of this association for perceptions of people with AIDS were derived from terror management theory, which proposes that mortality salience increases derogation of those who threaten people's worldviews unless those worldviews oppose prejudice, in which case mortality salience can increase acceptance of people who are otherwise threatening. Consistent with these hypotheses, conservative participants had less favorable impressions (Study 2) and liberal participants had more favorable impressions (Study 3) of a target with AIDS following a death reminder. Study 4 suggested that the decrease in prejudice among liberals following mortality salience was a genuine decrease in prejudice (as indicated by responses to an unobtrusive attitude measure), not just an increase in the desire to appear nonprejudiced. Theoretical and practical implications of these findings are discussed.  相似文献
