Can We Weight Satisfaction Score with Importance Ranks Across Life Domains?

The main purpose of this study was to investigate the utility of importance weighting when importance ranks were considered as the weighting values by (1) examining the range-of-affect hypothesis in the within-subject context and (2) comparing performances of weighted and unweighted satisfaction scores in predicting overall judgment of subjective well-being. Participants were 167 undergraduates at National Taiwan University. The mean age was 19.80 years (SD = 1.98). They were first asked to complete the measurements for global life satisfaction and overall QOL and then completed a QOL questionnaire for rating satisfaction, perceived have–want discrepancy on 12 life domains and ranking importance on these domains. Hierarchical linear modeling with a random-coefficients regression model was applied to examine the range-of-affect hypothesis in the within-subject context. Correlation analysis was applied to evaluate performances of weighted and unweighted satisfaction scores in predicting overall judgment of subjective well-being. Results of this study supported the range-of-affect hypothesis, showing that the relationship between item have–want discrepancy and item satisfaction is stronger for high importance items than low importance items for a given individual. Correlation analysis found that the four weighted satisfaction scores computed from the algorithms proposed by Hsieh (Social Indicators Research 61:227–240, 2003) were not superior to unweighted satisfaction score in predicting overall QOL and global life satisfaction. All these findings suggested that weighting satisfaction scores with importance ranks may not have theoretical basis and empirical contribution.     

On the Predictive Effect of Multidimensional Importance-Weighted Quality of Life Scores on Overall Subjective Well-Being

This study aimed to examine the effectiveness of importance weighting in predicting outcome variables in a hierarchical and multidimensional measurement context. A total of 146 undergraduate students (female = 76; mean age = 20.25) from two universities in Taiwan and China participated in this study. They evaluated their quality of life on 22 facets from the WHOQOL-BREF scale, which covers four domains (i.e., physical health, psychological health, social relationships, and environmental health). They were also asked to rate the importance of these 22 facets and items for three general subjective well-being indices, including overall quality of life, general health, and life satisfaction. A multiplicative formula was used to create importance-weighted scores for each facet, and four domain scores were obtained by averaging facet scores under specific domains. Results of regression analysis revealed that after applying the weighting procedure, the four domain scores did not account for more variances in the three indices for overall subjective well-being, and predictive effects of the four domain scores became less differential. Our findings suggest that importance weighting did not have its expected benefits but instead may negatively impact the predictive effects.     

Do We Need to Weight Satisfaction Scores with Importance Ratings in Measuring Quality of Life?

Trauer and Mackinnon (2001; Quality of life research 10, pp. 579–585) recently proposed that weighting satisfaction scores by importance ratings in measuring quality of life is undesirable and unnecessary. However, they didn’t use empirical data to support their claim. In this study, different weighting algorithms developed by Cummins (1997; Comprehensive Quality of Life Scale – Adult: Manual [Deakin, University Australia]), Raphael et al. (1996; Journal of Adolescent Health 19, pp. 366–375), Ferrans and Powers (1985; Advances in Nursing Science 8, pp. 15–24) and Frisch (1992; Comprehensive Casebook of Cognitive Therapy [Plenum Press, New York]) for measuring quality of life (QOL) were applied. Weighted scores computed from these weighting algorithms were compared with unweighted scores in predicting a global life satisfaction measure by correlation and moderated regression analyses. One hundred and thirty undergraduate students at National Taiwan University participated in the study voluntarily. They completed a 15-item questionnaire on quality of campus life developed by the authors. They also completed the Satisfaction with Life Scale (SWLS), a global life satisfaction measure developed by Diener et al. (1985; Journal of Personality Assessment 49, pp. 71–75). The correlation results revealed that the weighted scores computed from different algorithms didn’t have higher correlations to the SWLS than the unweighted scores. The moderated regression results also revealed that item importance did not moderate the relationship between item satisfaction and the overall life satisfaction. All these findings revealed that weighting satisfaction with importance is unnecessary. This paper was a part of the first author’s Master Thesis     

Examining the appropriateness of importance weighting on satisfaction score from range-of-affect hypothesis: hierarchical linear modeling for within-subject data

This study examines the range-of-affect hypothesis in a within-subject context using the weighting situation faced in quality of life (QOL) measurement. Data collected in Wu and Yao’s (2006b) study were used (332 undergraduates at National Taiwan University). The mean age was 19.80 years (std = 1.98). They completed a QOL questionnaire and indicated satisfaction, importance, and perceived have–want discrepancy on 12 life domains. Hierarchical linear modeling with a random-coefficients regression model was applied. At the first level (within-individual level), the satisfaction scores for each item were regressed on the have-want discrepancy, importance, and the interaction between have-want discrepancy and importance (have-want discrepancy ×  importance) of the same item. At the second level (between-individual level), the intercept, coefficients of have-want discrepancy, importance and the interaction between have-want discrepancy and importance at the first level were regarded as varying randomly over all participants. Results of this study supported the range-of-affect hypothesis, showing that the relationship between item have-want discrepancy and item satisfaction is stronger for high importance items than low importance items for a given individual. Implications for important weighting on item satisfaction scores were discussed.     

Importance is Not Unimportant: The Role of Importance Weighting in QOL Measures

The effect of relative domain importance as a weighting mechanism in quality of life (QoL) measures has been a topic of debate for decades. Studies investigating the role of domain importance in QoL measures have produced mixed results. The mixed results may very well be the consequences of a limited choice of global satisfaction or QoL measures, measurements of domain satisfaction, measurements of domain importance and weighting approaches applied to date. This study investigated the effect of importance weighting without assigning any arbitrary weighting function of domain importance. A cluster analysis was first used to classify individuals into groups, based on their perceived importance of various life domains, and then the relationship between global life satisfaction measure and the composite of domain satisfaction scores between these groups was compared. Results of this study showed that the relationship between global life satisfaction and composite of satisfaction scores did not remain consistent for respondents with different importance rankings of major life domains, which suggested an important effect of domain importance in QoL measures.     

Does Weighting Capture What’s Important? Revisiting Subjective Importance Weighting with a Quality of Life Measure

The present study evaluated subjective importance weighting using data collected with the Injection Drug User Quality of Life Scale (IDUQOL). Weighted and unweighted IDUQOL scores from 241 adults were correlated with convergent, discriminant, and criterion measures. Regression analysis was used to examine the contribution of importance ratings to scores on a global measure of life satisfaction and the corrected weighted IDUQOL total scores. Overall, the results showed that weighted scores did not perform better than unweighted scores in measuring quality of life. However, the mean satisfaction ratings for important domains correlated significantly higher with convergent measures than did the mean satisfaction ratings for unimportant domains. This finding suggests further attention needs to be paid to the meaning and measurement of subjective importance and how it may be incorporated more effectively into measures of quality of life.     

Do We Need to Weight Item Satisfaction by Item Importance? A Perspective from Locke’s Range-Of-Affect Hypothesis

Importance weighting is a common idea in quality of life (QOL) measurement. Based on the common idea that important domains should have more contributions to individuals’ QOL total score, the weighting procedure of multiplying item satisfaction by item importance was adopted in many QOL instruments. However, in Locke’s [1969, Organizational Behavior and Human Performance 4, pp. 309–336; 1976, in: M.D. Dunnette (eds.), Handbook of Industrial and Organizational Psychology (Rand McNally, Chicago), pp. 1297–1343] range-of-affect hypothesis, he indicated that the satisfaction evaluation of an item was determined by the have–want discrepancy, importance and their interaction (discrepancy × importance), implying that item satisfaction has incorporated the judgment of item importance, therefore, weighting an item satisfaction score with an item importance score is unnecessary. The purpose of this study was to examine the range-of-affect hypothesis in the context of QOL research. Three hundred and thirty two undergraduate students at National Taiwan University (NTU) participated in the study. Item satisfaction, importance and perceived have–want discrepancy were measured for 12 different life-area items. Global life satisfaction was measured as well. Regression analysis results showed that item importance and perceived have–want discrepancy have a significant interaction effect on item satisfaction, supporting Locke’s range-of-affect hypothesis. In addition, regression analysis results also showed that item importance and item satisfaction did not have a significant interaction effect on global satisfaction, suggesting that weighting item satisfaction score by item importance value does not have advantages in predicting global satisfaction. In a summary, the findings revealed that item satisfaction has incorporated the judgment of item importance, and, thus, the procedure of importance weighting on item satisfaction is unnecessary.     

Counting Importance: The Case of Life Satisfaction and Relative Domain Importance

The purpose of this study was to explore whether the use of relative domain importance as a weighting mechanism at the individual level improved the correlation between the global life satisfaction and domain satisfaction measures. Results from telephone interviews with adults 50 years old or above in Chicago suggest that compared to simple average of domain satisfactions, using discrete domain importance rating as a weighting factor did not improve the correlation between global life satisfaction measure and domain satisfactions. However, the correlation was improved by using domain ranking. The findings suggest that the weighted average of domain satisfactions using domain ranking is a better indicator of global life satisfaction than the simple sum or average of domain satisfactions.     

Psychometric Analysis of the Orientations to Happiness Questionnaire in Taiwanese Undergraduate Students

The aim of this study was to examine the psychometric properties of the Orientations to Happiness Questionnaire (OHQ; Peterson et al. in J Happiness Stud 6(1):25–41, 2005) in Taiwanese students. The participants were 578 undergraduate students (M_age = 18.64, SD = 1.02) and completed the OHQ, satisfaction with life scale (Diener et al. in J Personality Assess 49:71–75, 1985), and subjective happiness. Confirmation factor analysis indicated that a three-factor model with 17 items was the better fit model. Cross-validation also supported the modified Chinese version of the OHQ. Besides, the OHQ significantly predicted life satisfaction and subjective happiness with an exception of life of pleasure. Overall, it was concluded that the Chinese version of the OHQ would be useful for assessing individual’s orientations to happiness.     

A Note on Student Quality of Life

An aggregated sample of students (n = 3407) from the University of Northern British Columbia covering 7 of the 8 years from 1998 to 2005 is analyzed to show the relative and combined explanatory power of some life domain (e.g., satisfaction with family relations) and university-related variables (e.g., satisfaction with UNBC instructors) on some global quality-of-life variables (e.g., life satisfaction). It was found that, in combination with the life domain variables, the university-related variables added practically nothing to our explanatory power. The most powerful university-related variable was students’ satisfaction with their instructors.     

Should We Give Up Domain Importance Weighting in QoL Measures?

The purpose of this article is to examine the recent claims calling for abolishing domain importance weighting in quality of life (QoL) measures by considering the evidence conceptually and empirically. Based on a close review of evidence presented to date, it is suggested that using the range-of-affect hypothesis as a possible explanation of the poor performance of weighted satisfaction composite in predicting or correlating with global satisfaction or QoL measures can be beneficial to our understanding of the life satisfaction literature. However, given the conceptual focus and the empirical approach of the range-of-affect hypothesis presented in the life satisfaction context, using the range-of-affect hypothesis to argue against domain importance weighting raised more questions than answers. Calling for abolishing domain importance weighting in QoL measures, based on the evidence of range-of-affect hypothesis, is premature.     

Validation of the Wood’s Job Satisfaction Questionnaire among Taiwanese Nonprofit Sport Organization Workers

The purpose of this study was to examine the psychometric properties of Wood’s Job Satisfaction Questionnaire (JSQ) among Taiwanese workers. The participants were 341 nonprofit sport organization workers (M _age = 35.89, SD = 9.23) who completed the job satisfaction questionnaire, turnover intention scale, and organizational commitment. Confirmatory factor analysis was conducted to examine the validity of the JSQ. Results indicated that the model fit was satisfactory and a second-order factor accounts for the relationships among the first-order factors. In addition, the JSQ was, as expected, positively correlated with organizational commitment but is inversely correlated with turnover intention. The Cronbach’s α was 76 for the JSQ, indicating a satisfactory validity and reliability in the Taiwanese worker sample. We conclude that the JSQ is useful for assessing an employee’s satisfaction.     

Alegría! Flow in Leisure and Life Satisfaction: The Mediating Role of Event Satisfaction Using Data from an Acrobatics Show

The aim of the current study was to examine the role of satisfaction-with-event as a mediator in the relations between flow and life satisfaction based on the bottom-up theory (Andrews and Withey in Social indicators of well-being: Americans’ perceptions of life quality. Plenum, New York, 1976; Lee et al. in J Macromarketing 22(2): 158–169, 2002). Four hundred and thirty-four participants with a mean age of 35.60 (SD = 11.76) were recruited from the audience of a “Cirque du Soleil” acrobatics show, performed in Taiwan in 2009. Participants completed the flow scale (Csikszentmihalyi in Flow: the psychology of optimal experience. Harper & Row, New York, 1990), a satisfaction-with-event scale (Lin and Hsu in Mark Rev 3(4): 497–528, 2008), and a satisfaction-with-life scale (Diener et al. in J Pers Assess 49:71–75, 1985) immediately after viewing the show. Structural equation modeling was conducted to examine our hypothesis that satisfaction-with-event levels would fully mediate the relationship between flow and overall life satisfaction. Results supported our prediction and are discussed in terms of bottom-up theory. Implications of the study are also provided for the leisure managers.     

Validation of the WeDQoL-Goals-Thailand Measure: Culture-Specific Individualised Quality of Life

The aim of this study was to validate an individualised measure of quality of life (WeDQoL-Goals-Thailand). Three hundred and sixty-nine Thai people completed the WeDQoL by interview. Respondents rated (0–2) the perceived necessity for wellbeing of 51 goals (goal necessity), then rated (0–3) their satisfaction with the same goals (goal satisfaction). Weighted goal attainment (possible range 0–6) was computed (necessity x satisfaction). Psychometric validation used frequency distributions, Principal Components Analysis (PCA), and Cronbach’s alpha. Analysis of variance, t-tests, Kruskal–Wallis, Mann–Whitney U, Spearman’s correlation and multiple regression explored socio-demographic, geographic and economic differences. Respondents were aged 15–89 (mean 45.7, SD 18.0); 169 men, 200 women. For weighted goal attainment scores, PCA found a 44-item scale (α = 0.91) and three subscales (community/social/health, α = 0.90; house and home, α = 0.80; nuclear family, α = 0.81). Thai Individualised Goal Attainment (TIGA) scale and the three subscales were computed as the mean of contributing weighted goal attainment scores, after excluding goals considered ‘not necessary’ to each individual. Unweighted and individualised scores differed significantly with socio-demographic, geographic and economic indicators. In multiple regression, both Thai Unweighted Goal Satisfaction (TUGS) and TIGA scale scores were predicted by being married, living in the South and in a non-urban location. TIGA scores were also predicted by being over 25 years old. WeDQoL-Goals-Thailand has excellent psychometric properties. Individualised scores reflect each person’s perspective on wellbeing and are sensitive to subgroup differences. However, unweighted satisfaction scores give a broadly similar picture and involve less complex computation.     

How do Positive Views Maintain Life Satisfaction?

This study proposes three mediation pathways to explain how the positive views (perceived control, optimism and self-enhancement) proposed by Cummins and Nistico (Journal of Happiness Studies 3:37–69 2002) maintain life satisfaction. The three pathways were enhancing self-esteem, reducing have-want discrepancy and changing importance perceptions. Two hundred and seventy-two undergraduates from Central Taiwan University of Science and Technology and Nan Kai Institute of Technology voluntarily participated in this study. Questionnaires measuring sense of control, optimism, self-enhancement, self-esteem, have-want discrepancy and importance of life domains, and global life satisfaction were administered to participants in a classroom setting. Correlation and structural equation modeling analyses were conducted to examine the mediation effects of these three pathways. Generally, results of correlation and structural equation modeling analyses were consistent with hypothesized relations among variables and showed that the relationship between positive views and life satisfaction was completely mediated by self-esteem, have-want discrepancy and shifting tendency of importance perception, indicating that the three pathways of enhancing self-esteem, reducing have-want discrepancy and changing importance perceptions had unique effects to explain how positive views maintain life satisfaction.     

Importance has been Considered in Satisfaction Evaluation: an Experimental Examination of Locke’s Range-of-affect Hypothesis

Importance weighting is a common practice in quality of life (QOL) measurement research. Based on the widespread idea that important domains should make a greater contribution to individuals’ QOL total score, the weighting procedure of multiplying item satisfaction by an item’s importance has been adopted in many QOL instruments. Locke’s [1969, Organizational Behavior and Human Performance 4, 309–336; 1976, Handbook of Industrial and Organizational Psychology. Rand McNally, Chicago, pp. 1297–1343] range-of-affect hypothesis indicated that a satisfaction evaluation is determined by the have-want discrepancy, importance, and the interaction of the have-want discrepancy and importance, implying that a satisfaction evaluation incorporates the judgment of importance and weighting the satisfaction score with the importance score is unnecessary. The purpose of the current study was to address the issue of importance weighting by examining Locke’s range-of-affect hypothesis in the context of QOL research. A within-subject experiment was conducted to see if, given a varying amount of discrepancy, participants would reveal whether or not satisfaction/dissatisfaction is related to the dimension of importance placed on the object. Forty undergraduate students at National Taiwan University participated in the current study. Results revealed that the association between have-want discrepancy and object satisfaction is stronger on the high important dimension than the less important dimension. Generally, the results were consistent with Locke’s range-of-affect hypothesis, revealing that a satisfaction evaluation has incorporated the judgment of item importance, suggesting that the procedure of importance weighting is unnecessary. This paper was a part of the first author’s Master’s Thesis.     

Gratitude and Adolescent Athletes’ Well-Being

Two cross-sectional studies were conducted to examine the relationships between gratitude and athletes’ well-being. Study 1 examines the relationship between dispositional gratitude and well-being, while Study 2 investigates the relationship between sport-domain gratitude and well-being. In Study 1, 169 Taiwanese senior high school athletes (M = 16.43, SD = 0.7 years) were administered the Gratitude Questionnaire (GQ; McCullough et al. 2002, Journal of Personality and Social Psychology, 82(1), 112–127), Team Satisfaction Scale (Walling et al. 1993, Journal of Sport & Exercise Psychology, 15, 172–183), Satisfaction with Life Scale (SWLS; Diener et al. 1985, Journal of Personality Assessment, 49, 71–75), and the Athlete Burnout Questionnaire (ABQ; Raedeke and Smith, 2001, Journal of Sport & Exercise Psychology, 23(4), 281–306). In Study 2, a separate sample of 265 adolescent athletes (M = 16.47 years, SD = 0.7) were administered the modified Sport-domain GQ, Team Satisfaction Scale, and ABQ. Study 1 results showed that dispositional gratitude positively predicts team satisfaction and life satisfaction, and negatively predicts athlete burnout. Findings from Study 2 revealed that sport-domain gratitude positively predicts team satisfaction and negatively predicts athlete burnout. A stronger gratitude and well-being relationship was observed in Study 2. This research provides the initial verification that gratitude and adolescent athletes’ well-being are related. Possible mechanism of this relation, limitations, and practical implications are discussed.     

Determinants of Health and the Quality of Life in the Bella Coola Valley

The aim of this investigation is to obtain some baseline self-reported data on the health status and overall quality of life of all residents of the Bella Coola Valley of British Columbia aged 17 years or older, and to measure the impact of a set of designated health determinants on their health and quality of life. In the period from August to November 2001, a variety of procedures were used to ensure that all eligible residents of the Valley received a copy of our questionnaire, and 687 useable questionnaires were obtained for our working dataset. Health status was measured by SF-36 and the U.S. Centers for Disease Control healthy days items. Thirty-one items were used to measure the Provincial Health Officer’s designated determinants of health in four clusters, namely, biological, social and economic, health behaviours and health services determinants. Quality of life was measured by satisfaction levels in 13 specific domains of life (e.g., family, financial security), four global items (e.g., happiness, life satisfaction) and one global Subjective Well-Being Index. Besides obtaining baseline figures on all our measures for the Valley, we made some comparisons among our figures and those from other areas, e.g., Prince George, BC. Most of the measures indicated that the health status and quality of life of Bella Coola Valley residents were lower than those of Prince George residents. For the sample as a whole, SF-36 scores on the eight dimensions ran from 82.3 (physical functioning) to 50.0 (social functioning), with a mean of 62.7. Residents in the Valley averaged 6.5 days in the past 30 in which their health was physically not good, 5.5 days when it was mentally not good and 4.1 days when their health limited their usual daily activities. Eleven percent of respondents described their general health as “excellent” and another 27% said it was “very good”. On a 7-point scale from 1=very dissatisfied to 7=very satisfied, respondents had average life satisfaction and satisfaction with the overall quality of life scores of 5.5. For specific domains of life, the lowest mean level of satisfaction was reported for federal and provincial government officials (3.3) and the highest was reported for living partners and personal safety around home (5.8). Regarding bivariate relations, each of the eight dimensions of SF-36 was significantly correlated with a single item measure of general health, and five of the eight were significantly correlated with the number of good health days. Happiness and the Subjective Well-Being Index were positively but moderately correlated with six of the eight dimensions, and life satisfaction was positively correlated with five. Age was negatively related to general health, but positively related to life satisfaction. Not being of aboriginal descent was positively related to all of the four global health indicators and to the Subjective Well-Being Index. Education was positively related to the four global health measures but not to the three global quality of life measures. The Social Support and Good Family Indexes were positively related to all seven global measures. There was a positive correlation between six of the seven global measures and the frequency with which respondents participated in activities sponsored by voluntary organizations. Frequency of smoking was negatively associated with every global dependent variable except the Physical Health Index. Frequency of skipping meals was negatively associated and average hours of sleep per night was positively associated with all seven global measures. Turning to multivariate relationships, the four clusters of health determinants explained from 12% (SF-36 Mental Health Index) to 24% (general health) of the variance in the dependent global health variables, and from 20% (happiness) to 26% (Subjective Well-Being Index) of the variance in the dependent global quality of life variables. Adding domain satisfaction scores to the total set of predictors allowed us to explain from 20% (SF-36 Mental health Index) to 29% (general health) of the variance in the dependent global health variables, and from 39% (happiness) to 62% (life satisfaction) in the dependent global quality of life variables. By including measures of social support and good family relationships in our set of health determinants, we practically guaranteed that the latter would be relatively strongly predictive of global quality of life.     

Individual quality of life: can it be accounted for by psychological or subjective well-being?

There is ongoing discussion in the scientific literature about the need for a more theoretical foundation to underpin quality of life (QoL) measurement. This paper applied Keyes et al.’s [J. Pers. Soc. Psychol. 82 (2002) 1007] model of well-being as a framework to assess whether respondents (n = 136 students) focus on elements of subjective well-being (SWB), such as satisfaction and happiness, or on elements of psychological well-being (PWB), such as meaning and personal growth, when making individual QoL (IQoL) judgments using the Schedue of the Evaluation of Individual Quality of Life (SEIQoL). The Keyes et al.’s model was confirmed and explained 41% of the variance in SEIQoL scores. Both SWB and PWB were correlated with the SEIQoL Index Score and SWB was found to be an important mediating variable in the relationship between PWB and SEIQoL. When analyzing different well-being combinations, respondents with high SWB/high PWB had significantly higher SEIQoL scores than did those with low SWB/low PWB. Respondents with high PWB/high SWB had higher SEIQoL scores than did those with high PWB/low SWB. Longitudinal studies in different patient groups are needed to explore the dynamic relationship between IQoL and well-being. Further investigation of the relationship between PWB and SWB with other instruments purporting to measure QoL would contribute to an enhanced understanding of the underlying nature of QoL.     

Health and quality of life of older people,a replication after six years

Replicating a survey of 875 people 55 years old or more undertaken in September 1999 throughout the former Northern Interior Health Region (NIHR) of British Columbia, in September 2005 a sample of 656 people completed a 22-page questionnaire. The average age of the respondents was 68, with a range running from 55 to 96 years, and 64% were women. Responses to the SF-36 questionnaire indicated that for male respondents aged 55–64, the mean score for the 8 dimensions was 76.1. This mean was a bit higher than the 74.4 mean of 1999. For male respondents aged 65 and older the mean was 69.0, which was also higher than the 68.3 mean of 1999. For females aged 55–64, the mean score for 8 dimensions was 73.1, versus 73.0 in 1999. For female respondents aged 65 and older, the mean score was 67.0, versus 65.4 in 1999. Based on these mean scores for the 8 dimensions, then, it is fair to say that the overall health status of males and females aged 55 years and older in the region in 2005 was at least as good as (i.e., the same as or better than) that in 1999. Comparing 28 average figures for the 2005 respondents on satisfaction with specific domains of life (e.g., financial security, health, sense of meaning) and three global indicators (satisfaction with life as a whole and with the overall quality of life, and happiness) with those of the 1999 respondents, we found that the scores for the 2005 sample were at least as high as those of the other sample. Thus, it seems fair to say that the perceived quality of life of older people in the former NIHR so far as it is revealed in domain and global satisfaction and happiness scores, is at least as good as the perceived quality of life of a similar sample in 1999. Although a large majority perceived increases in crime in the 2 year periods prior to both surveys, smaller percentages of the 2005 sample than of the 1999 sample thought that crime had increased over the past two years, avoided going out at night, feared for their safety, had crime-related worries, engaged in crime-related defensive behaviours and were actually the victims of any crimes. Therefore, it seems fair to say that, so far as crime-related issues are concerned for the two samples of seniors responding to our surveys, there is more evidence of improvement than of deterioration. Applying stepwise multiple regression, each of the eight dependent variables was explained on the basis of four clusters of predictors separately and then a final regression was run using only the statistically significant predictors from the four clusters. Broadly speaking, 7 SF-36 health status scales explained from 28% to 45% of the variance in the 8 dependent variables, running from satisfaction with the overall quality of life (28%) to the single item measure of general health (45%). The seven predictors in the Social Relations cluster explained from 7% of the variance in the SF-36 General Health scale scores to 57% of the variance in the Life Satisfaction scores. The four predictors in the Problems cluster explained from 10% of the variance in the SF-36 General Health scale scores to 24% of the variance in the SWLS scores. The 11 predictors in the Domain Satisfaction cluster explained from 14% of the variance in the SF-36 General Health scale scores to 64% of the variance in the SWB scores. Putting all the significant predictors together for each dependent variable, in the weakest case, 4 of 11 potential predictors explained 33% of the variance in the SF-36 General Health scale scores and in the strongest case, 9 of 15 potential predictors explained 70% of the variance in Life Satisfaction scores. Among other things, these results clearly show that respondents’ ideas about a generally healthy life are different from, but not independent of, their ideas about a happy, satisfying or contented life, or about the perceived quality of their lives or their subjective wellbeing. Finally, the 7 core discrepancy predictors of MDT plus incomes were used to explain the eight dependent variables. From 13% of the variance in the SF-36 General Health scale scores to 57% of the variance in SWLS scores was explained using those predictors. Based on an examination of the Total Effects scores for the predictors of the 8 dependent variables, the most influential predictors were Self-Wants, followed by Self-Others and then Self-Best. In other words, the most influential discrepancy predictors of respondents’ overall life assessments were those between what respondents have versus what they want, followed by what they have versus what others of the same age and sex have, and then by what they have versus the best they ever had in the past.
