疼痛恐惧对疼痛的影响及其认知机制

疼痛恐惧是把将要出现的疼痛刺激视为主要威胁而产生的一种恐惧,它会影响与疼痛相关的感知觉、注意、回避行为以及安慰剂止痛的效果.疼痛恐惧的认知模型主要有活动回避模型、恐惧-回避模型以及内感受性恐惧条件模型.未来的研究要进一步探究疼痛恐惧的认知机制,完善疼痛恐惧的认知模型并扩展疼痛恐惧的研究方法.     

疼痛恐惧相关的注意偏向及其矫正

疼痛恐惧是影响和维持慢性痛的重要因素。不同材料和被试类型情况下, 疼痛恐惧均主要作用于个体对疼痛相关信息的早期注意加工阶段, 表现为注意警觉模式。该注意模式使个体将注意维持在疼痛上, 从而干扰了对非疼信息的注意能力。矫正疼痛恐惧相关注意偏向可以改善疼痛体验。未来研究应采用更具生态效度的任务测量疼痛恐惧相关的注意偏向及其神经基础, 进一步考察矫正疼痛恐惧相关注意偏向能否改善慢痛患者的忧郁和功能丧失等问题。     

疼痛恐惧的形成、泛化与消退

疼痛恐惧源于把疼痛等同于伤害的灾难化信念及对疼痛的负性解释, 它在慢性疼痛和能力丧失的发生和发展过程中起着重要作用。疼痛恐惧可以通过联合学习和观察学习等方式获得, 并且在具有相似特征的刺激中存在泛化现象。通过教育干预和等级暴露疗法等可以成功消退疼痛恐惧, 在消退过程中要控制安全信息等因素的不良影响。在疼痛恐惧的获得与消退中, 主要有杏仁核, 脑岛和前扣带皮层等脑区参与。未来的研究可以集中在深入探讨疼痛恐惧形成中的泛化及消退后的恢复、再巩固等现象, 加强其临床上的应用, 并综合心理、生物和认知神经科学, 研究疼痛恐惧的获得、泛化与消退的深层机制。     

Attitude Toward Asian Americans: Theory and Measurement

A theoretical framework to account for Whites' attitudes toward Asian Americans was developed and tested in 3 studies. An Attitude Toward Asians (ATA) scale was developed and found to be valid and reliable. Consistent with the framework, a negative factor and a positive factor were found to underlie attitudes toward Asian Americans. As expected, negative attitudes were shown to stem from both negative and positive instrumental attributes, whereas positive attitudes stemmed from positive instrumental and noninstrumental attributes. Predictions regarding emotional reactions to Asian Americans and attitude ambivalence were supported. Attitudes toward Asian Americans were also shown to influence judgments of African Americans. Implications and future research directions are discussed.

A Counseling Practitioner's Primer to the Use of Multidimensional Scaling

Applications of multidimensional scaling (MDS) to counseling practice are discussed, and the author's use of MDS as a tool in a counseling training group is described.     

Men without jobs: Some correlates of age and length of unemployment

Measures of reported health change, financial stress, financial strain, and commitment to the labour market were used with a sample of 954 unemployed working-class men, selected to cover equally all levels of age and several levels of length of unemployment. It was found that psychological deterioration, financial stress and strain, and labour market commitment were greatest among middle-aged unemployed men. Deterioration in health and degree of financial strain were found to be greater among men unemployed for longer periods in contrast with those who had more recently become unemployed, but no association was observed between length of unemployment and the measures of financial stress and commitment to the labour market. The probability of having an employed wife was found to be negatively associated with length of unemployment, consistent with the operation of a household strategy for income maintenance.     

META-ANALYSIS OF PERSONALITY-JOB PERFORMANCE RELATIONS: A REPLY TO ONES, MOUNT, BARRICK, AND HUNTER (1994)

Tett, Jackson, and Rothstein's (1991) meta-analysis identified higher average correlations for personality in predicting job proficiency than did Barrick and Mount's (1991). Ones et al. suggest that discrepancies between the two studies involving the Big Five personality dimensions are due to certain procedural differences. In this reply, we show that their arguments do not adequately explain the noted discrepancies. We also show that, because personality traits correlate significantly with job performance both positively and negatively beyond chance levels, use of absolute values, contrary to Ones et al., is important in meta-analyses involving personality. Addressing all of Ones et al.3 statistical concerns, re-analysis of Tett et al.k main data set results in slightly lower mean validities (e.g., .24 vs.29 for fully corrected values based on confirmatory estimates), and renders non-significant the job analysis/no job analysis distinction found to be significant in the original study. Tett et al.'s main conclusions, however, remain unchanged. We suggest that Barrick and Mount's lower mean validities may be due to their averaging signed correlations, pooling exploratory and confirmatory findings, and to the use of different inclusion criteria for selecting source studies.
