Measurement and definition of sexual orientations have increasingly become a central focus in both research design and public policy debates. This paper reviews major methods, and their theoretical underpinnings, for the definition and measurement of sexual orientations, highlighting their limitations and pitfalls, both practical and conceptual. The increasing politicization of this area is discussed and cautioned against. Recommendations, both general and geared toward measurement concerns with adolescent populations, are made. A specific measurement strategy, which can be utilized at a number of different levels, is detailed.  相似文献

Research has shown that emotional avoidance and anxiety sensitivity are associated with more self-reported fear and distress in response to laboratory fear challenge procedures. The present study aimed to expand upon this work and examined how emotional avoidance and anxiety sensitivity are related to emotional and physiological responses to an observational fear challenge procedure. To accomplish this aim, a carefully screened, non-clinical sample (N = 43) was administered the Acceptance and Action Questionnaire (AAQ), a measure of emotional avoidance, and the Anxiety Sensitivity Index (ASI). Participants then engaged in an observational fear challenge paradigm. During the fear challenge, participants watched mock panic attacks while emotional (e.g., fear and panic) and skin conductance levels were assessed. Consistent with expectation, emotional avoidance and anxiety sensitivity were positively associated with more self-reported fear and more severe panic symptoms to the challenge procedure. However, anxiety sensitivity was more highly associated with self-reported fear and panic symptoms in response to the challenge procedure than emotional avoidance. Emotional avoidance and anxiety sensitivity were not associated with levels of physiological arousal to the observational fear challenge procedure. Discussion focuses on the interplay between emotional avoidance, anxiety sensitivity, and the development of vicarious fear responses and how these constructs may contribute to the pathogenesis of anxiety disorders.  相似文献

The purpose of the current study was to examine the relationship between behavioural inhibition (BI) and anxious symptoms within a diathesis-stress framework, using a short-term prospective design. In addition, we examined whether BI acts as a specific vulnerability to anxious symptoms, or as a common vulnerability to both anxious and depressive symptoms. At time 1, 384 children in grades 3 through 6 completed self-report measures of BI, anxious symptoms, and depressive symptoms. Six weeks later, they completed self-report measures of hassles, anxious symptoms, and depressive symptoms. Results demonstrated that children with high BI who experienced high levels of hassles during the 6-week follow-up interval showed increases in anxious symptoms, but not depressive symptoms.  相似文献

Gunby, Rapp, Bottoni, Marchese and Wu (2017) taught three children with autism spectrum disorder to follow an instructor's gaze shift to select a specific item; however, Gunby et al. used different types of prompts with each participant. To address this limitation, we used a progressive training model for increasing gaze shift for three children with autism spectrum disorder. Results show that each participant learned to follow an adult's shift in gaze to make a correct selection. In addition, two participants displayed the skill in response to a parent's gaze shift and with only social consequences; however, the third participant required verbal instruction and tangible reinforcement to demonstrate the skill outside of training sessions.  相似文献

Previous research has demonstrated the association between family functioning and depression. This study evaluated family functioning and perceived social support in men and women in Shanghai who had received a diagnosis of a major depressive disorder (N = 100), including sixty-six women and thirty-four men. The relationship between family functioning and social support of outpatients with major depressive disorders was explored using the Chinese Family Assessment Device and the Multidimensional Scale of Perceived Social Support. The scores from all dimensions of family functioning for both men and women indicated that depressed men and women all reported experiencing unhealthy family functioning. The clinical implications of these findings for the developing practice of family therapy in China are discussed.  相似文献

This study served to replicate and extend our previously obtained hierarchical model of the relationships among general anxiety vulnerabilities, specific anxiety vulnerabilities and specific anxiety manifestations including panic symptoms, health anxiety, obsessive-compulsive symptoms and worry. Questionnaires assessing these variables, as well as positive affectivity and depressiveness, were administered to 125 outpatients seeking treatment for panic disorder, social anxiety disorder, obsessive-compulsive disorder, generalized anxiety disorder or major depressive disorder. The results, using a clinical sample, were highly consistent with the hierarchical model obtained in the previous study using a student sample. A more elaborate model, based on published theoretical and empirical evidence, was identified and tested, and similar results were obtained. Negative affectivity had expected direct positive effects on all of the specific anxiety and depression manifestations, with the exception of health anxiety, which showed a negative relationship, and OCD symptoms, which showed no relationship. Positive affectivity was found to be a specific risk factor for depression, while intolerance of uncertainty was found to be a specific risk factor for worry and depression. Finally, anxiety sensitivity appears to be a significant risk factor for panic and health anxiety.  相似文献
