A self-determination theory approach to problematic drinking and intimate partner violence

Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression.     

Friend or foe? Postdivorce hostility among recently divorced individuals

High levels of hostility often occur during and postdivorce and may significantly affect the quality of life, parent–child relationships, and social functioning of divorcees. Moreover, hostility may predict aggressive and violent behavior. This study sought to (a) compare average general hostility levels of a large sample of Danish divorcees to the norms of the general adult Danish population, (b) compare general hostility levels between male and female divorcees, and (c) investigate the explanatory value of various sociodemographic and divorce-related factors on postdivorce general hostility and whether these factors differ across gender. Cross-sectional baseline data (N = 1,856) from a larger randomized controlled trial study was used in this study. Normative data from a general sample of Danish adults (N = 2,040) was used for comparisons of hostility levels between our study sample and the Danish background population. This study found that male and female divorcees did not report significantly different hostility levels. However, participants reported significantly higher hostility levels postdivorce than the comparative Danish norm sample. Significant predictors of postdivorce hostility were lower age, lower educational level, infidelity as a reason for divorce, higher degree of postdivorce conflict, worse communication with the former spouse, the former spouse as the initiator of the divorce, and new partner status with neither divorcees having a new partner, or only the former spouse having a new partner. The predictive strength of the factors did not differ across gender. The findings may be especially relevant for interventions targeting problematic outcomes postdivorce (e.g., preventing aggressive behavior).     

Development of the Collectivist‐Sensitive Trait Forgivingness Scale

Mounting evidence suggests that experiences of forgiveness vary across cultures. However, culturally sensitive conceptualizations of forgiveness lack empirical support, in part because psychometrically sound instruments designed to capture unique aspects of forgiveness in non‐Western cultures are rare. For this reason, we developed the Collectivist‐Sensitive Trait Forgivingness Scale (TFS‐CS), which is designed to measure trait forgivingness within societies characterized by a blend of individualistic and collectivistic worldviews. In Study 1 (N = 597), exploratory factor analysis revealed a 16‐item three‐factor structure of third‐party forgiveness, collectivistic forgiveness, and interpersonal resentment among South Africans. In Study 2 (N = 897), the three‐factor model replicated in an independent South African sample. Findings also offered preliminary evidence supporting the construct validity of the TFS‐CS. Overall, these studies support a conceptualization of trait forgivingness with similarities and differences relative to Western models and highlight the importance of appreciating the influence of culture when measuring forgiveness.     

Paradoxical sleep deprivation impairs acquisition, consolidation, and retrieval of a discriminative avoidance task in rats

The aim of the present study was to investigate the effects of paradoxical sleep deprivation (PSD) for 96 h on the learning/memory processes in rats submitted to the plus-maze discriminative avoidance task (PM-DAT), which simultaneously evaluates learning, memory, anxiety and motor function. Four experiments were performed in which rats were submitted to: (1) post-training and pre-test PSD; (2) post-training or pre-test PSD; (3) pre-training PSD or pre-training paradoxical sleep (PS) rebound (24 h) and (4) pre-test PSD rebound. Concerning Experiment I, post-training and pre-test PSD induced memory deficits, an anxiolytic-like behavior and an increase in locomotor activity. In Experiment II, both post-training PS-deprived and pre-test PS-deprived groups showed memory deficits per se. However, only the pre-test PS-deprived animals presented anxiolytic-like behavior and increased locomotor activity. In Experiment III, pre-training PS-deprived rats showed learning and memory deficits, anxiolytic-like behavior and increased locomotor activity. A 24h-sleep recovery period after the PSD abolished the learning and memory deficits but not anxiety and locomotor alterations. Finally, sleep rebound did not modify acquisition (Experiment III) and retrieval (Experiment IV). This study strengthened the critical role of paradoxical sleep (but not sleep rebound) in all the phases of learning and memory formation. In addition, it suggests that PSD effects on acquisition and consolidation do not seem to be related to other behavioral alterations induced by this procedure.     

Tracking exceptional human capital over two decades

Talent-search participants (286 males, 94 females) scoring in the top 0.01% on cognitive-ability measures were identified before age 13 and tracked over 20 years. Their creative, occupational, and life accomplishments are compared with those of graduate students (299 males, 287 females) enrolled in top-ranked U.S. mathematics, engineering, and physical science programs in 1992 and tracked over 10 years. By their mid-30s, the two groups achieved comparable and exceptional success (e.g., securing top tenure-track positions) and reported high and commensurate career and life satisfaction. College entrance exams administered to intellectually precocious youth uncover extraordinary potential for careers requiring creativity and scientific and technological innovation in the information age.     

Subjective health complaints

A variety of subjective illnesses with few or no objective findings have appeared at regular intervals as epidemics in our society under different labels. There are few or no objective findings that might explain the "disease" or the complaints go beyond what is regarded as "reasonable" by the physician. Muscle pain and other types of subjective health complaints are among the most frequent reason for encounters with general practitioners, and one of the major causes for sickness absence. The prevalence of subjective health complaints is very high, with at least 75% of the population reporting one or more subjective health complaints the past 30 days. From a statistical point of view, it is "normal" to have complaints. It is when they become intolerable that assistance is required. The difficult thing is that this threshold is individual and subjective. The psychiatric definitions of these complaints, therefore, refer only to the tip of an iceberg.     

Correlates of relative lethality and suicidal intent among deliberate self-harm patients

Conflicting findings have been reported regarding the relationship between the potential lethality of acts of deliberate self-harm (DSH) and suicidal intent, and how each relates to patient characteristics. This study examines the relationship of suicidal intent of DSH to lethality, the relationship of both to patient characteristics, and determines if intent or lethality are risk factors for repetition of DSH. Potential lethality and Suicide Intent Scale (SIS) scores for DSH episodes were examined in a representative sample of 150 patients presenting to a general hospital. Follow-up interviews were completed 12 to 20 months later. Lethality was strongly associated with high intent. Both lethality and intent were associated with male gender. Suicidal intent but not lethality was associated with the presence of psychiatric disorder and depression. Intent was significantly correlated with hopelessness scale score. Although intent was correlated with both depression and self-esteem scale scores, these correlations became nonsignificant when the effect of hopelessness was removed. Repetition of DSH during the follow-up period was related to neither lethality nor intent scores for the original episodes. Lethality and suicidal intent, although related, have somewhat different correlates. Both should be considered when assessing DSH patients, but their relationship to further suicidal behavior does not appear to be straightforward.     

Telling tales in school: extended contact interventions in the classroom

Extended contact has demonstrated its effectiveness in promoting more positive intergroup attitudes among children in previous experimental research. The current project evaluates the use of extended contact interventions involving story‐telling in two novel school settings: the United States (N = 213) and Italy (N = 222) among children aged 5–12 years. Findings indicate support for the effectiveness of the interventions in these two locations among younger minority and majority children but call into question the durability of positive outcomes. Applications and implications are discussed.
