Subjective quality of life, perceived control and dispositional optimism among older people

Objectives: To examine whether the subjective quality of life (QOL) of elderly people is held under homeostatic control, and to investigate the role of perceived control and dispositional optimism in the maintenance of subjective QOL.
Method: 100 older people (M=75.6 years) and a control group of 107 younger people (M=20.1 years) completed a self-report survey.
Results: Both groups had a level of subjective QOL within the normal range. The older group reported higher levels of secondary control and optimism, but similar levels of primary control, as the younger group. Primary control and optimism predicted subjective QOL for both groups. Secondary control was a significant predictor (or the younger group, however it was only marginally significant for the older group. Optimism accounted for the most subjective QOL variance for both groups.
Conclusions: The finding that the subjective QOL of the older group lay within the normative range supports the proposal that their subjective QOL is being successfully maintained under bomeostatic control. However, they appear to have an increased reliance on secondary control. The fact that dispositional optimism captures the predictive variance of perceived control, is an important finding adding to the understanding of subjective QOL maintenance.

Event valence and unrealistic optimism

The effect of event valence on unrealistic optimism was studied. 94 Deakin University students rated the comparative likelihood that they would experience either a controllable or an uncontrollable health-related event. Valence was manipulated to be positive (outcome was desirable) or negative (outcome was undesirable) by varying the way a given event was framed. Particiapants either were told the conditions which promote the event and rated the comparative likelihood they would experience it or were told the conditions which prevent the event and rated the comparative likelihood they would avoid it. For both the controllable and the uncontrollable events, unrealistic optimism was greater for negative than positive valence. It is suggested that a combination of the 'motivational account' of unrealistic optimism and prospect theory provides a good explanation of the results. 

`I`m less at risk than most guys`: gay men`s unrealistic optimism about becoming infected with HIV

Among the self-justifications that gay men use when engaging in high-risk sex is the thought that they are less at risk than most gay men. Two explanatory models of such 'unrealistic optimism' (UO) have been proposed: while the motivational account holds that UO arises because it serves the function of bringing comfort, the cognitive account holds that UO serves no particular function, being simply a by-product of normal cognitive strategies. This study investigated predictions derived from the motivational account. Gay men uninfected with HIV (n = 88) answered two test questions, requiring them to estimate, respectively, their own risk of becoming infected and that of the average gay man. The questions were presented in the two possible orders, and were either separated or not separated by unrelated filler material. The great majority of the men (89%) exhibited UO. Neither question order nor the interpolation of filler material affected responses to either test question. The results were inconsistent with the motivational account, but explicable in terms of the cognitive account. It seems that the cognitive account provides the better explanation of at least that form of UO measured in this study. Implications for AIDS educators are discussed.

Explaining gay men's unrealistic optimism about becoming infected with HIV

Among the self-justifications that gay men use when deciding to have unprotected intercourse is the thought that they are at less risk than most gay men. Two explanatory models of such 'unrealistic optimism' (UO) have been proposed: while the motivational account holds that UO serves the function of bringing comfort, the cognitive account holds that UO serves no particular function, being simply a by-product of normal cognitive strategies. This study tested the prediction, derived from the motivational account, that highlighting the salience of the self-other comparison should increase UO. Gay men uninfected with HIV (n = 122) estimated both their own risk of contracting various health problems - among them, becoming infected with HIV - and that of the average gay man. The purported aim of collecting the data was varied, so as to either make the self-other comparison central to the aim or render one of the two types of estimate irrelevant to the aim. No effect on UO was found. It seems that the cognitive account provides a better explanation than does the motivational account of at least that form of UO measured in this study. Implications for AIDS education are discussed.

Event valence and unrealistic optimism: further evidence

Unrealistic optimism is assessed using either a single question, the rating of own likelihood of experience an event compared to that of the average person, or two questions, separate rating of own likelihood and that of the average person. The effect of using valence on more unrealistic optimism was studied in a sample of 175 students using the two-question measure. Valence was manipulated to be positive, i.e., outcome was desirable, or negative, i.e., outcome was undesirable, by 'framing' the same event appropriately. Unrealistic optimism was greater for negative than positive valence. The effect was of the same direction and magnitude as that found by Gold and Martyn (2003) using the single-question measure. The relationship between valence and unrealistic optimism does not depend on whether unrealistic optimism is assessed with one or two questions.

Non-equivalence of direct and indirect measures of unrealistic optimism

Individuals typically believe that they are less likely than the average person to experience negative events. Such “unrealistic optimism” (UO) has been assessed in two ways: directly (via a single question, requiring comparison of own risk to that of the average person) and indirectly (via separate questions about own risk and that of the average person). The study examined the equivalence of the direct and indirect measures of female students' UO for unwanted pregnancy. Participants (N = 120) answered questions about their own risk, that of the average female student, and their own risk relative to that of the average female student; responses and response times were recorded. There was only a moderate association between direct- and indirect-UO. Direct-UO was strongly associated with estimate of own risk, but only moderately associated with estimate of the average student's risk. Response times for the comparative risk and own risk questions did not differ, but participants took significantly longer to answer the question about average student's risk. The results suggest that the two measures of UO are not equivalent, but, rather, that individuals answering a comparative risk question focus mainly on their own risk, at the expense of that of the average person.

Unrealistic optimism about becoming infected with HIV: different causes in different populations

People tend to believe that their chance of experiencing undesirable events is lower and their chance of experiencing desirable events is higher than that of the average person like them. Two explanatory models of such 'unrealistic optimism' (UO) have been proposed: While the motivational account holds that UO serves the function of bringing comfort, the cognitive account holds that UO serves no particular function, being simply a by-product of normal cognitive strategies. UO for HIV infection was studied in samples of uninfected students (Study 1, n = 68) and gay men (Study 2, n = 63). In each case, participants rated either their relative likelihood of becoming infected (negative valence condition) or their relative likelihood of remaining uninfected (positive valence condition). As predicted, in Study 1 UO was greater where valence was negative and in Study 2 valence had no effect. The findings suggest that the students' UO is better explained by the motivational account, while the gay men's UO is better explained by the cognitive account. Implications for AIDS education are discussed.

Accounting measurement in the religious perspective : conservatism or optimism

This paper concerns about accounting measurements from the socio cultural values’ perspectives. By applying Hofstede (1980), Gray (1988), and Perera (1989) studies, first of all, the study develops a theory to concern about accounting values in a religious perception. Then Islam, as one of the most debatable religion in the world, is considered as an instance. Islamic compliance accounting measurement has developed in next stage to understand how the accounting value could be different from this viewpoint from the Western conservative historical cost. This study theoretically proves that Islamic compliance accounting measurement conforms to the exit price method which is different from the Western complaisance accounting measurement.

Unrealistic optimism and event threat

Individuals typically exhibit “unrealistic optimism” (UO), the belief that they are less likely than the average person to experience a negative event. This may be because, fearing the event, they try to reassure themselves by distorting their reasoning to conclude that they are at comparatively little risk. If this is so, the greater the “event threat” (i.e., the more serious the event's consequences and/or the greater the likelihood that those consequences will be experienced), the more reassurance should be required, and the greater the UO that should be observed. This prediction was tested in a study in which students (N = 148) were informed about a type of heart disease that could develop in later life due to inadequate diet when young. The risk attributable to diet was stated to be either slight (low-threat condition) or great (high-threat condition). Participants were asked to rate their own risk and that of the average student of developing the disease; question order was counterbalanced. The effects of event threat and question order were found to interact: event threat affected UO in the predicted way, but only when the question about own risk came first. The results are explained in motivational terms. Implications for health education are discussed.

Volunteering and well-being : do self-esteem, optimism, and perceived control mediate the relationship?

Volunteers play a vital role in modern societies by boosting the labor force within both the public and private sectors. While the factors that may lead people to volunteer have been investigated in a number of studies, the means by which volunteering contributes to the well-being of such volunteers is poorly understood. It has been suggested through studies that focus on the absence of depression in volunteers that self-esteem and sense of control may be major determinants of the increased well-being reported by volunteers. This is consistent with the homeostatic model of subjective well-being, which proposes that self-esteem, optimism, and perceived control act as buffers that mediate the relationship between environmental experience and subjective well-being (SWB). Using personal well-being as a more positive measure of well-being than absence of depression, this study further explored the possible mediating role of self-esteem, optimism, and perceived control in the relationship between volunteer status and well-being. Participants (N = 1,219) completed a 97-item survey as part of the Australian Unity Wellbeing project. Variables measured included personal well-being, self-esteem, optimism, and a number of personality and psychological adjustment factors. Analyses revealed that perceived control and optimism, but not self-esteem, mediated the relationship between volunteer status and personal well-being.

Group composition : influences of optimism and lack thereof

Lesson video and video-stimulated post-lesson interviews were used to study the role of optimism in collaborative problem solving in a Grade 5/6 classroom for the purpose of informing group composition. This study focuses on the activity of two students who differed on the personal characteristic 'optimistic orientation'. It examines how the presence or absence of an optimistic orientation to failures (Seligman, 1995) contributed to these students' interactions with their groups and opportunities for collaborative creation of new knowledge. One group collaborated to develop mathematical knowledge that was new to each group member and the other group did not. These findings raise questions about how to group students who are not yet optimistic to enable collaborative activity, and how to build optimism.

Engaged to learn pedagogy : theoretically identified optimism-building situations

Associations between resilience or optimism (Seligman, 1995) and the inclination to explore unfamiliar challenging problems in mathematics have been identified (Williams, 2005, 2008). This raised questions about how to build optimism to enhance mathematical performance. In this study, a theoretical framework was formulated to study optimism-building situations (Seligman, 1995; Csikszentmihalyi, 1992). By interrogating ‘Engaged to Learn’ pedagogy (Williams, 2000) through a video-stimulated interview study, situations theoretically expected to be optimism building were identified.
