Confirmatory factor analysis of different versions of the Body Shape Questionnaire applied to Brazilian university students

This study aimed at evaluating the validity, reliability, and factorial invariance of the complete (34-item) and shortened (8-item and 16-item) versions of the Body Shape Questionnaire (BSQ) when applied to Brazilian university students. A total of 739 female students with a mean age of 20.44 (standard deviation = 2.45) years participated. Confirmatory factor analysis was conducted to verify the degree to which the one-factor structure satisfies the proposal for the BSQ's expected structure. Two items of the 34-item version were excluded because they had factor weights (λ) < 40. All models had adequate convergent validity (average variance extracted = .43–.58; composite reliability = .85–.97) and internal consistency (α = .85–.97). The 8-item B version was considered the best shortened BSQ version (Akaike information criterion = 84.07, Bayes information criterion = 157.75, Browne–Cudeck criterion = 84.46), with strong invariance for independent samples (Δχ²λ(7) = 5.06, Δχ²Cov(8) = 5.11, Δχ²Res(16) = 19.30).     

A Professor's Experience With Loss: An Autobiographical Case Study

The purpose of this article is to present an autobiographical case study chronicling a psychology professor's experience with grief and the loss of her father during the early stages of her academic career. The article highlights the obstacles faced in dealing with anticipatory grief but also demonstrates how clinicians and researchers may use adverse life circumstances to develop research and applied programs centered around their experiences. Rooted in Viktor Frankl's work on logotherapy, the author demonstrates how traumatic experiences can help psychologists find meaning and purpose in their work. Directions for future research focusing on larger scale populations are addressed.     

议程与习惯性反应对学习时间分配的影响：来自眼动的证据

采用眼动记录技术,操作三种词对位置,探讨议程与习惯性反应对学习时间分配的影响。实验一设置无时间限制条件,结果发现,20名大学生被试均优先选择左边的项目,项目的自定步调学习时间不存在词对位置效应。结果表明,被试的习惯性反应影响项目选择,不影响自定步调学习时间。实验二设置有时间限制条件,结果发现,20名大学生被试均优先选择容易项目并分配更多的时间学习容易项目,且容易项目的选择存在词对位置效应。结果表明,议程驱动主导被试的项目选择和自定步调学习时间,但不能完全消除习惯性反应对项目选择的影响。     

关于日间手术模式的研究及应用进展

日间手术最早始于英国,指在1个工作日内完成患者入院、手术以及出院,该模式在欧美国家得到广泛接受并推广.安全开展日间手术必须具备良好的设备条件,同时拥有包括手术医师、麻醉师及专业护士在内的合格规范的日间手术团队,并在患者选择、术前准备与评估、麻醉与围手术期镇痛、术后恶心呕吐预防控制、康复与离院标准、随访与再入院等各方面遵循相应地规范性要求,从而最大程度地保障医疗安全与患者利益.日间手术模式正符合我国当前医改对“安全、有效、方便、价廉的医疗卫生服务”这一目标的要求,近年来也日益受到我国临床工作者的重视.     

中年人睡眠相关行为与高血压关系的病例对照研究

为探讨中年人睡眠相关行为与高血压发病风险之间的关系。本研究采用1：1匹配的病例对照研究法;资料收集方法采用问卷调查法;资料处理分析采用t检验及多元条件Logistic回归模型分析法。结果显示中年人病例组与对照组睡眠质量存在显著性差异（t=6．19,P〈0．05）。（1）睡眠相关行为（每日睡眠不足、夜间睡眠不足、睡眠时点延迟、睡眠质量差、入睡困难、每周入睡困难次数增加及打鼾等因素）多元条件Logistic回归模型的OR值和95％CI分别为[（OR=5．07,95％CI：3．12～8．21）;（OR=5．57,95％CI：3．43～9．04）;（OR=2．27,95％CI：1．49～3．47）;（OR=2．17,95％CI：1．60～2．94）;（OR=3．36,95％CI：1．47～7．69）;（OR=1．55,95％CI：1．08～2．24）;（OR=2．69,95％CI：1．86～3．88）]。（2）适当午睡为（OR=0．85,95％CI：0．74～0．98）。（3）早起与否（OR=1．40,95％CI：0．87～2．20）。因此（1）中年人睡眠相关行为与高血压发病密切相关,每日睡眠不足、夜间睡眠不足、睡眠时点延迟、睡眠质量差、入睡困难、每周入睡困难次数增加及打鼾等因素可能为高血压发病的危险因素;（2）中年人适当午睡可能是高血压发病的保护性因素;（3）是否早起与高血压发病关系尚不清晰。     

中美辅助生殖技术伦理规范的比较研究

Synchronous and time-lagged effects between occupational self-efficacy and objective and subjective career success: Findings from a four-wave and 9-year longitudinal study

We integrated research on the dimensionality of career success into social-cognitive career theory and explored the positive feedback loop between occupational self-efficacy and objective and subjective career success over time (self-efficacy → objective success → subjective success → self-efficacy). Furthermore, we theoretically accounted for synchronous and time-lagged effects, as well as indirect reciprocity between the variables. We tested the proposed model by means of longitudinal structural equation modeling in a 9-year four-wave panel design, by applying a model comparison approach and indirect effect analyses (N = 608 professionals). The findings supported the proposed positive feedback loop between occupational self-efficacy and career success. Supporting our time-based reasoning, the findings showed that unfolding effects between occupational self-efficacy and objective career success take more time (i.e., time-lagged or over time) than unfolding effects between objective and subjective career success, as well as between subjective career success and occupational self-efficacy (i.e., synchronous or concurrently). Indirect effects of past on future occupational self-efficacy via objective and subjective career success were significant, providing support for an indirect reciprocity model. Results are discussed with respect to extensions of social-cognitive career theory and occupational self-efficacy development over time.

The Affective Consequences of Minority Stress Among Bisexual,Pansexual, and Queer (Bi+) Adults: A Daily Diary Study

Bisexual, pansexual, and queer (bi+) individuals are at increased risk for depression and anxiety. These disparities are hypothesized to be due to the unique, minority-specific stressors that they experience. Prior research supports that bi+ stressors are associated with depression and anxiety, but nearly all studies have been cross-sectional, limiting our understanding of how experiencing bi+ stress influences individuals’ levels of depression and anxiety as they occur in their day-to-day lives. To address this gap, we examined the daily associations between bi+ stressors (discrimination, internalized stigma, rejection sensitivity, and identity concealment) and depressed/anxious mood in a 28-day diary study. Participants were 208 bi+ individuals who completed daily measures of bi+ stressors and depressed/anxious mood. We tested unlagged (same-day) and lagged (next-day) associations, and we also tested whether internalized stigma, rejection sensitivity, and identity concealment functioned as mechanisms underlying the daily associations between discrimination and depressed/anxious mood. Participants reported higher depressed/anxious mood on days when they reported higher discrimination, internalized stigma, rejection sensitivity, and identity concealment. There were significant unlagged indirect effects of discrimination on depressed and anxious mood via internalized stigma and rejection sensitivity, and there was also a significant unlagged indirect effect of discrimination on anxiety via identity concealment. However, none of the lagged associations were significant. Results suggest that bi+ stress is related to same-day, but not next-day, depressed/anxious mood. The nonsignificant lagged associations could reflect that bi+ individuals are using adaptive coping skills in response to bi+ stress, or that other experiences throughout the day have stronger influences on next-day mood.
