Measuring optimism in Hong Kong and mainland Chinese with the revised Life Orientation Test

Abstract To examine the utility of a Chinese version of the revised Life Orientation Test (CLOT-R) to measure optimism among Chinese students, the CLOT-R, the General Health Questionnaire, a physical symptom checklist and measures of constructs related to optimism were administered to a total of 404 Hong Kong and 328 mainland Chinese college students. Results indicated that the CLOT-R exhibited convergent and discriminant validity in the two samples. Nevertheless, confirmatory factor analysis of the responses to the CLOT-R showed that a one-factor interpretation only applied to the data of the Hong Kong but not the mainland sample. When the test was applied to mainland Chinese, the positively and the negatively worded items split into two factors. These findings were discussed in the light of issues related to generalisation of the revised Life Orientation Test across cultures.

Optimism, positive affectivity, and salivary cortisol

OBJECTIVES Research on stress and salivary cortisol has focused almost exclusively on the effects of negative psychological conditions or emotional states. Little attention has been drawn to the impact associated with positive psychological conditions, which have been shown recently to have significant influences on neuroendocrine regulation. The aim of this study is to examine the impact of optimism and positive affect on salivary cortisol with the effects of their negative counterparts controlled for. DESIGN Optimism and pessimism, and positive and negative affectivity were studied in relation to the diurnal rhythm of salivary cortisol in a group of 80 Hong Kong Chinese, who provided six saliva samples over the course of a day on two consecutive days. The separate effects of optimism and positive affect on two dynamic components of cortisol secretion, awakening response, and diurnal decline were examined. METHODS Optimism and pessimism were measured using the Chinese version of the revised Life Orientation Test while generalized affects and mood states were assessed by the Chinese Affect Scale. An enzyme-linked immunoabsorbent assay kit (EIA) developed for use in saliva was adopted for the biochemical analysis of cortisol. Testing of major group differences associated with positive psychological conditions was carried out using two-way (group by saliva collection time) ANOVAs for repeated measures with negative psychological conditions and mood states as covariates. RESULTS Participants having higher optimism scores exhibited less cortisol secretion in the awakening period when the effect of pessimism and mood were controlled. This effect was more apparent in men than in women who had higher cortisol levels in the awakening period. Optimism did not have similar effect on cortisol levels during the underlying period of diurnal decline. On the other hand, higher generalized positive affect was associated with lower cortisol levels during the underlying period of diurnal decline after the effects of negative affect and mood states had been controlled. Generalized positive affect did not significantly influence cortisol secretion during the awakening period. CONCLUSIONS These findings suggest that positive psychological resources including optimism and generalized positive affect had higher impact on cortisol secretion than their negative counterparts, and point to the need for increased attention to the potential contribution of positive mental states to well-being.

The Utility of the Revised Life Orientation Test to Measure Optimism among Hong Kong Chinese

To examine the utility of the revised Life Orientation Test (LOT-R) to measure optimism among Hong Kong Chinese, the psychometric properties of the revised and the original versions of the Life Orientation Test were compared. A total of 248 Hong Kong Chinese undergraduates were studied in the fall and 165 of these participants were tested again 5 months later. Results indicated that the LOT-R is a reliable and valid measure of dispositional optimism among Hong Kong Chinese. Confirmatory factor analysis showed that the LOT-R represents a one-factor model of optimism better than does the original version. Despite its brevity, the LOT-R is psychometrically sounder than the original sclae. These findings point to the feasibility of replacing the original with the revised scale in future research among Hong Kong Chinese. However, the utility of the revised test in cross-cultural comparisons may still be limited by the absence of emic components. Further research on optimism in the Chinese people with the LOT-R...

Perception of Environmental Hazards in Hong Kong Chinese

A public sample of Hong Kong Chinese (N = 167) rated the levels of threat of 25 environmental hazards and gave quantitative judgments to six risk characteristics for each hazard. It was found that women, older participants, and less educated individuals found the hazards to be more threatening to the environment than did men, younger participants, and more educated individuals, respectively. A new spatial model emerged from a principal component analysis carried out on responses to six risk characteristics. Instead of replicating the well-documented factors of unknown risk versus dread risk, we found a structure defined by a known and dread risk factor and a controllable risk factor. Findings were discussed in light of potential influences of the Confucian heritage on the perception of risks among Hong Kong Chinese.

Differential Predictive Power of the Positively versus the Negatively Worded Items of the Life Orientation Test

A self-report measure of dispositional optimism, the Life Orientation Test, was administered to a group of 202 Hong Kong undergraduates. Consistent with prior findings, factor analysis yielded a two-factor solution with all positively worded items loaded on the first factor and all the negatively worded items loaded on the second. Prediction of physical symptom reports from scores on the two subscales was then tested with 85 subjects randomly selected from the original sample. Only the complete test and the subscale defined by the positively phrased items predicted symptom levels concurrently as well as prospectively over 3 wk. The negative subscale suggested by previous research as tapping pessimism rather than dispositional optimism showed no significant correlation with symptom levels. Moreover, when scores of the positive rather than the negative subscale were controlled, the significant correlation between scores on the Life Orientation Test and symptom reports was eliminated. These findings suggested a multidimensional view of the test and that the positive subscale may be sufficient to measure optimism validly. Implications of these for the personality dimensions of positive versus negative affectivity are also discussed.

Resilience is associated with better recovery in Chinese people diagnosed with coronary heart disease

This study investigated the impact of personal resilience (a composite measure of optimism, perceived control and self-esteem) on outcome measures in 67 Chinese coronary heart disease patients in response to an 8-week rehabilitation programme. The effect of personal resilience on posttraumatic growth attributed to the onset of heart disease was also examined. Results indicated that coronary heart disease patients high in personal resilience achieved better outcomes than those low in personal resilience, as indicated by higher physical and mental summary measures in SF-36, lower cholesterol levels and better performance on the 6 min walk test. Moreover, personal resilience was demonstrated to be a significant predictor of the level of posttraumatic growth although the rehabilitation programme exerted a weak mediating effect on the link between personal resilience and posttraumatic growth. Findings were discussed in relation to clinical implications of the construct of personal resilience and the intervention programme.

The moderating effect of optimism on the relation between hassles and somatic complaints.

The relations between hassles, dispositional optimism, and prospective reports of physical symptoms were examined in a group of 90 Hong Kong undergraduates. Given that most hassle scales are confounded by physical and psychological symptomatology, a decontaminated scale specifically tailored to the experiences of college students was used. Multiple regression analyses indicated that hassle scores and the interaction of hassles and optimism uniquely and reliably predicted symptom reporting. Optimism, however, did not reliably predict symptom reports when effects of hassles and the interaction of hassles and optimism were controlled. Inspection of the interaction showed that optimism predicted symptom scores only at high levels of hassles. The underlying mechanisms were discussed in the light of previous data linking optimism and adaptational outcomes via coping. It was suggested that further pursuit of the connection between optimism and coping in relation to measures of life stress would be worthwhile.

The effects of job-search motives and coping on psychological health and re-employment: A study of unemployed Hong Kong Chinese.

We examine the influences of job-search motives and coping behaviours on psychological well-being and re-employment on 104 unemployed Hong Kong Chinese within a longitudinal context. Participants were tested on two different occasions separated by eight months. Results indicated that, at the first survey, use of coping strategies predicted higher psychological well-being while higher financial hardship was associated with decreased mental health. Results of ANOVA indicated that participants who scored high in employment commitment at the first survey were more likely to regain employment subsequently. Contrary to prior findings reported in studies with Western samples, psychological well-being was not affected by employment status at the follow-up survey. The psychological well-being of participants deteriorated from the first to the second survey. These findings point clearly to the significance of psychological factors in determining the response of Hong Kong Chinese to job loss. Implications of these data for future unemployment research among Chinese are discussed.

Health beliefs, optimism, and health-related decisions: A study with Hong Kong Chinese

T he Health Belief Model (HBM; Rosenstock, 1966) is the most widely used psychological theory of health-related behaviours but its applicability to non-Western, especially Asian, populations has not been systematically studied. The main objective of the current study was to examine the effects of components of the HBM and dispositional optimism on preventive intention in two separate samples of 220 Hong Kong Chinese adults and 340 Hong Kong Chinese adolescents. Two HBM variables, benefits and barriers, were experimentally manipulated for an imaginary flu outbreak and a hypothetical vaccine. Optimism in the two samples was assessed using the Chinese revised Life Orientation Test (Lai et al., 1998). Participants indicated their intention to take the hypothetical vaccine after reading information for each of the treatment combinations defined by the two HBM variables. The order of the presentation of each of the six treatment conditions was counterbalanced. Results of ANOVA showed that the effects of the two...

Bicultural Self, Multiple Social Identities, and Dual Patriotisms Among Ethnic Chinese in Hong Kong:

This research tests a model of bicultural self and its implications for social identity (Study 1) and compares the effects of bicultural self and social identity on patriotism (Study 2). Studies are grounded in Hong Kong’s cultural-political context, where the century-long bicultural development of Chinese and Western selves is now realigning with Hong Kong’s recent reunification with China and the resultant expectation to identify with and be patriotic toward China. Results from 761 bilingual university students show that biculturals with strong Chinese and Western selves are psychologically more integrated than others with weaker selves. They are the only group to strongly endorse multiple social identities as Chinese, Hongkonger, and Hongkong Chinese. The Chinese self enhances patriotism toward China and Hong Kong, whereas the Western self and social identities enhance patriotism toward Hong Kong only.
