SAS and SPSS macros to calculate standardized Cronbach’s alpha using the upper bound of the phi coefficient for dichotomous items 总被引:1,自引:0,他引:1
Cronbach’s α is widely used in social science research to estimate the internal consistency of reliability of a measurement
scale. However, when items are not strictly parallel, the Cronbach’s α coefficient provides a lower-bound estimate of true
reliability, and this estimate may be further biased downward when items are dichotomous. The estimation of standardized Cronbach’s
α for a scale with dichotomous items can be improved by using the upper bound of coefficient ϕ. SAS and SPSS macros have been
developed in this article to obtain standardized Cronbach’s α via this method. The simulation analysis showed that Cronbach’s
α from upper-bound ϕ might be appropriate for estimating the real reliability when standardized Cronbach’s α is problematic. 相似文献

The author examined the association between emotional autonomy and problem behavior among Chinese adolescents living in Hong Kong. The respondents were 512 adolescents, 16 to 18 years of age, who were interviewed for a cross-sectional study. Three dimensions of emotional autonomy including individuation, nondependency on parents, and de-idealization of parents were significantly and positively correlated with the amount of problem behavior the participants engaged in during the past 6 months. Using a simple linear multiple regression model, the author found that problem behavior was associated with only one aspect of emotional autonomy-individuation. Results indicated that the relationship between problem behavior and three aspects of emotional autonomy was similar in both individualistic and collectivistic societies. 相似文献

This study examined the association between 8 aspects of friend intimacy and 3 measures of psychosocial adjustment (self-esteem, deviant behavior, and purpose in life) among Hong Kong Chinese adolescents. The respondents were 289 students between 16 and 19 years of age from a cross-sectional study in Hong Kong. Bivariate correlation and multiple regression analyses revealed (a) friend intimacy was positively associated with self-esteem and purpose in life, and (b) friend intimacy was negatively correlated with deviant behavior. Results indicated that friend intimacy is an important variable that affects some aspects of psychosocial adjustment. Moreover, results of multiple regression analyses indicated that different measures of friend intimacy are related to deviant behavior and purpose in life. Therefore, it is crucial to study the relationship between different aspects of friend intimacy and different aspects of psychosocial adjustment among adolescents. 相似文献

Observing noxious injury to another’s hand is known to induce corticospinal inhibition that can be measured in the observer’s
corresponding muscle. Here, we investigated whether acquired pain synesthetes, individuals who experience actual pain when observing injury to another, demonstrate less corticospinal inhibition than
do controls during pain observation, as a potential mechanism for the experience of vicarious pain. We recorded motor-evoked
potentials (MEPs) induced at two time points through transcranial magnetic stimulation while participants observed videos
of a hand at rest, a hypodermic needle penetrating the skin, a Q-tip touching the skin, and a hypodermic needle penetrating
an apple. We compared MEPs in three groups: 7 amputees who experience pain synesthesia, 11 nonsynesthete amputees who experience
phantom limb pain, and 10 healthy controls. Results indicated that the pain synesthete group demonstrated significantly enhanced
MEP response to the needle penetrating the hand, relative to the needle not having yet penetrated the hand, as compared with
controls. This effect was not observed exclusively in the same muscle where noxious stimulation was applied. We speculate
that our findings reflect a generalized response to pain observation arising from hyperactivity of motor mirror neurons not
involved in direct one-to-one simulation but, rather, in the representation of another’s experience. 相似文献

To examine the association between the perception of racial discrimination and the lifetime prevalence rates of psychological disorders in the three most common ethnic minorities in the United States, we analyzed data from a sample consisting of 793 Asian Americans, 951 Hispanic Americans, and 2,795 African Americans who received the Composite International Diagnostic Interview through the Collaborative Psychiatric Epidemiology Studies. The perception of racial discrimination was associated with the endorsement of major depressive disorder, panic disorder with agoraphobia, agoraphobia without history of panic disorder, posttraumatic stress disorder, and substance use disorders in varying degrees among the three minority groups, independent of the socioeconomic status, level of education, age, and gender of participants. The results suggest that the perception of racial discrimination is associated with psychopathology in the three most common U.S. minority groups. 相似文献

This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3‐month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2‐month and 3‐month intervention periods. 相似文献

The aim of this study was twofold: first, to examine the lasting effects of working hours on later job performance and well-being (i.e. emotional exhaustion and work engagement); second, to delineate the protective role of psychological detachment in the highly demanding Chinese work setting featuring long working hours. We employed a panel design in which all variables were measured twice, with six months in between the waves. Data were obtained from 323 Chinese employees working in diverse industries in Taiwan. Analysing the panel data with structural equation modelling (SEM) techniques, we found that working hours were positively associated with emotional exhaustion and negatively associated with work engagement and job performance, measured six months later. Detachment moderated the effects of working hours on later work engagement and job performance. Specifically, detachment attenuated the negative relationships between working hours and work engagement and job performance. The present study extends the recovery research in the West by demonstrating the protective role of detachment in the East Asian societies with important managerial implications. 相似文献

Suicide attempts constitute a serious clinical problem. People who have attempted suicide are at an elevated risk for additional suicide attempts, but there is limited evidence regarding the predictors of suicidality of suicide attempters following case management services. In the present study the indicators of suicidality after case management were examined. A total of 1,056 subjects who had recently attempted suicide were recruited from January 1, 2011, to June 30, 2011. The suicide prevention center of Kaohsiung City in Taiwan provided case management services and followed up on suicide attempt cases for 6 months. The salient factors for repeat suicide attempts were estimated using a logistic regression analysis. The results showed that multiple factors, including a “willingness to receive mental health services during a crisis,” “social support,” “a history of mental disorders,” and “a history of suicide,” could predict repeat suicide attempts with hazard ratios (0.58, 0.54, 3.84, 1.51) and 95% confidence interval (0.39–0.86, 0.36–0.83, 2.41–6.10, 1.03–2.21). The four factors mentioned above were the most accurate predictors of subsequent suicidality when case management services were utilized after 6 months of follow‐up. The findings of our study could help clarify future strategies for suicide prevention. 相似文献
