The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions. 相似文献

This study used the interpersonal–psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS. 相似文献

In the theoretical framework of dynamic motivational activation, this study reveals the dynamics of antimarijuana public service announcement (PSA) processing, especially the processing of co‐occurring positive and negative content. It specifies the important role of endogenous feedback dynamics of the information processing system and teases them apart from exogenous message effects. As suggested by real‐time psychophysiological responses (heart rate, skin conductance level, and facial electromyography), the copresence of positive and negative content is most attention eliciting and is not moderated by individuals' marijuana experience. Marijuana experience, however, increases attention to arousing content in the PSAs, increases smiling responses to positive content, and escalates arousal to the PSAs in general. Implications for designing and evaluating PSAs and health campaigns are discussed. 相似文献

Four parents enrolled in a Responsive Teaching class carried out experiments using procedures they had devised for alleviating their children's problem behaviors. The techniques used involved different types of reinforcement, extinction, and punishment. One parent increased the frequency of the wearing of an orthodontic device during five daily time checks by making an immediate monetary payoff contingent on wearing the device. A second parent increased the number of points earned for doing daily household tasks by providing back-ups for which the points could be exchanged. The parents of a 4-yr-old boy decreased the frequency of whines, cries, and complaints by removing social attention when such behavior occurred. A mother decreased the duration of time it took for her 5-yr-old daughter to get dressed by making permission to watch television contingent on dressing within 30 min of the time she got up in the morning. Brief reversals of contingencies were used to show causal relationships between the procedures used and the changes in behavior. Checks on the reliability of measurement were made by persons present in the home. 相似文献

This investigation examined the effects of 3 item characteristics—the average number of words per item, within-scale variability in item length, and item “direction”—on internal consistency reliability and interitem correlation. In Study 1, we examined the effects of these variables on overall scale-level reliability using 444 subscales from 9 personality scales. In Study 2, we examined interitem correlation at the paired-item level using 477 nonredundant item pairs from 14 personality scales. Lower scale reliability was associated with more average words per item, greater within-scale variability in item length, and a greater percentage of reverse-keyed items. Similarly, smaller interitem correlations were associated with a greater degree of mismatch in item length between the paired items and with a mismatch (vs. match) in the items' respective “directions.” The pattern of results across both studies supports our notion that lower internal consistency results from increased context switching; that is, from the confusion that occurs when respondents must switch back and forth between the interpretive frames pertaining to short versus long items, or between items pertaining to one pole of a personality dimension and its “opposite” pole. Suggestions for maximizing the internal consistency of personality scales are proposed. 相似文献
