Background Impulsivity critically relates to many psychiatric disorders. Given the multi-faceted construct that impulsivity represents, defining core aspects of impulsivity is vital for the assessment and understanding of clinical conditions. Choice impulsivity (CI), involving the preferential selection of smaller sooner rewards over larger later rewards, represents one important type of impulsivity. Method The International Society for Research on Impulsivity (InSRI) convened to discuss the definition and assessment of CI and provide recommendations regarding measurement across species. Results Commonly used preclinical and clinical CI behavioral tasks are described, and considerations for each task are provided to guide CI task selection. Differences in assessment of CI (self-report, behavioral) and calculating CI indices (e.g., area-under-the-curve, indifference point, steepness of discounting curve) are discussed along with properties of specific behavioral tasks used in preclinical and clinical settings. Conclusions The InSRI group recommends inclusion of measures of CI in human studies examining impulsivity. Animal studies examining impulsivity should also include assessments of CI and these measures should be harmonized in accordance with human studies of the disorders being modeled in the preclinical investigations. The choice of specific CI measures to be included should be based on the goals of the study and existing preclinical and clinical literature using established CI measures.
We investigated correlates of partner abuse in male same-sex relationships in a randomly selected community sample (N = 186). We included factors associated with abuse in heterosexual relationships, as well as factors of relevance to gay relationships. We assessed perpetration and receipt of partner abuse to examine whether variables were associated independently with abuse perpetration and/or receipt. Correlates of same-sex partner abuse were largely parallel to established correlates of heterosexual abuse. Income, education, and attachment orientation were associated with bidirectional partner abuse, and family violence and substance use were uniquely associated with victimization. Further, there were factors unique to same-sex partner abuse; HIV status and public outness were associated with bidirectional partner abuse, and internalized homophobia was uniquely associated with abuse perpetration.
Previous studies of abuse in male same-sex relationships have been limited by convenience samples and/or by incomplete assessments of partner abuse. We examined patterns of same-sex partner abuse in a random sample of 284 gay and bisexual men. Respondents reported on perpetration and receipt of physical, psychological, and sexual abuse over multiple time frames, as well as injuries resulting from abuse. Almost all respondents reported psychological abuse, more than one-third reported physical abuse, and 10% reported having engaged in unwanted sexual activity because of partner force or threats of force. More than half of recipients of partner violence reported sustaining injury. We found strong associations between different forms of abuse, and between severity of abuse receipt and perpetration.
The purpose of the study of 147 healthy primiparous women is to investigate the relationship between maternal adaptation during pregnancy and postpartum. This report is part of a larger study of relationships between family dynamics and maternal adaptation during childbearing in Norway, Sweden and the US. Variables included maternal adaptation, age, social status, mother's employment, type of birth, length of hospitalization and mother infant time together in the hospital. Mothers reporting greater adaptation during pregnancy reported greater adaptation postpartum. Mothers who believed themselves adapted indicated that they were better prepared for labour, had more control over their birth experience, a better relationship with their partner, and perceived greater participation in child care from their partner. Few differences were found in maternal adaptation among all mothers, and few relationships were found among selected sociodemographic variables and maternal adaptation. Formation of maternal identity and mother's confidence in her ability to cope with the tasks of motherhood was affected by mothers' prenatal identification with the motherhood role, supporting the notion that knowing what to expect provides a sense of control. Mothers' prenatal identification with the motherhood role directly or indirectly affected her satisfaction with motherhood. Nurses may want to develop practice strategies to support these findings.
Disordered eating is a serious and under‐recognized problem in people with diabetes. This narrative review summarizes the research contributions made by psychological science over the past 25 years to the study of disordered eating in people with type 1 or type 2 diabetes, and identifies gaps and future directions relevant to both healthcare professionals and researchers. Key focus areas of psychological research investigating disordered eating in people with diabetes have been: (1) defining and classifying types of disordered eating; (2) identifying demographic, diabetes‐specific and psychosocial correlates of disordered eating, and developing theoretical models of disordered eating in people with type 1 diabetes; (3) identifying the physical and psychosocial consequences of disordered eating; and (4) developing screening measures to identify disordered eating in people with type 1 diabetes. Psychological science has made significant contributions over the past 25 years to our understanding of the nature of this problem and the multiple factors which may interrelate with disordered eating in people with diabetes. Key areas for further attention include: (1) a better definition of disordered eating subtypes in people with type 1 diabetes; (2) characterizing disordered eating in people with type 2 diabetes; and (3) developing multidisciplinary, evidence‐based prevention and treatment interventions for comorbid disordered eating and diabetes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
