Psychometric Properties of the Satisfaction With Food-Related Life Scale: Application in Southern Chile

The Spanish Journal of Psychology, 2015

This study aimed to assess the effect of satisfaction with food-related life on life satisfaction among inhabitants of the main municipalities of central Chile. A survey was applied to a sample of 1,277 people, distributed proportionally by municipality. The questionnaire included the following scales: SWLS (Satisfaction with Life Scale), SWFL (Satisfaction with Food-related Life) and the Health-Related Quality of Life Index (HRQOL). Questions were asked regarding eating habits inside and outside the home, time available for meals at home, the assessment of five sources of happiness and the demographic characteristics of those surveyed. An ordered logit model was proposed, in which the dependent variable was satisfaction with life. Satisfaction with life was significantly related to the respondent’s socioeconomic status, self-perception of health, degree of satisfaction with food-related life, monthly food expenditure, time available for supper with the family (p < .01); gender, ...

Background: Eating is one of the most frequent human behaviors, but there are few studies that relate eating and subjective well-being. Typologies of people were distinguished and characterized according to their level of satisfaction with life and food in central Chile. Method: A survey was applied to a sample of 1,277 people in the main municipalities of this area, distributed proportionally by municipality. The questionnaire included the SWLS scales (Satisfaction with Life Scale), SWFL (Satisfaction with Food-related Life), Health-Related Quality of Life Index (HRQOL), Subjective Happiness Scale (SHS), and respondents' demographic characteristics and eating habits were also ascertained. Results: Using hierarchical cluster analysis, three typologies were distinguished with significant differences in the scores on the SWLS, SWFL, SHS, self-perception of health, days with physical or mental problems in the last month, sociodemographic characteristics and frequency with which the...

A measure of satisfaction with food-related life is developed and tested in three studies in eight European countries. Five items are retained from an original pool of seven; these items exhibit good reliability as measured by Cronbach's alpha, good temporal stability, convergent validity with two related measures, and construct validity as indicated by relationships with other indicators of quality of life, including the Satisfaction With Life and the SF-8 scales. It is concluded that this scale will be useful in studies trying to identify factors contributing to satisfaction with food-related life. r

Background: Nutrition is one of the major determinants of successful aging. The Satisfaction with Food-related Life (SWFL) scale measures a person's overall assessment regarding their food and eating habits. The SWFL scale has been used in older adult samples across different countries in Europe, Asia and America, however, there are no studies that have evaluated the cross-cultural measurement invariance of the scale in older adult samples. Therefore, we evaluated the measurement invariance of the SWFL scale across older adults from Chile and Ecuador. Methods: Stratified random sampling was used to recruit a sample of older adults of both genders from Chile (mean age = 71.38, SD = 6.48, range = 60-92) and from Ecuador (mean age = 73.70, SD = 7.45, range = 60-101). Participants reported their levels of satisfaction with food-related life by completing the SWFL scale, which consists of five items grouped into a single dimension. Confirmatory factor analysis (CFA) was used to examine cross-cultural measurement invariance of the SWFL scale. Results: Results showed that the SWFL scale exhibited partial measurement invariance, with invariance of all factor loadings, invariance in all but one item's threshold (item 1) and invariance in all items' uniqueness (residuals), which leads us to conclude that there is a reasonable level of partial measurement invariance for the CFA model of the SWFL scale, when comparing the Chilean and Ecuadorian older adult samples. The lack of invariance in item 1 confirms previous studies with adults and emerging adults in Chile that suggest this item is culture-sensitive. We recommend revising the wording of the first item of the SWFL in order to relate the statement with the person's life. Conclusions: The SWFL scale shows partial measurement invariance across older adults from Chile and Ecuador. A 4-item version of the scale (excluding item 1) provides the basis for international comparisons of satisfaction with food-related life in older adults from developing countries in South America.

In order to identify variables which have an influence on satisfaction with life among Mapuche persons of the Araucanía Region, Chile, a survey was applied to 400 Mapuche subjects in Temuco. The questionnaire included the SWLS (Satisfaction with Life Scale) and SWFL (Satisfaction with Food-related Life) scales, life-styles, food, and sociodemographic characteristics. Multinomial logit and probit models were proposed, in which the dependent variable was satisfaction with life. Both models proved significant (P < 0.01), but the logit model provided a better explanation of the construct. The results indicate a significant relation between satisfaction with life on the one hand and access to means of satisfying the basic needs associated with the concept of quality of life and maintenance of identity on the other. The probability of a high degree of satisfaction with life in a Mapuche person rises if he (she) possesses a greater number of goods, lives in the country, has higher education, has a partner, spends more than Ch $100,000 (US $200) per month on food, frequently consumes Mapuche food, leads an orderly life and is satisfied with his food. The discussion relates the results to the factors which influence the construction of cultural identity and the impact on this of traditional food practices

To characterize types of university students based on satisfaction with life domains that affect eating habits, satisfaction with food-related life and subjective happiness. A questionnaire was applied to a nonrandom sample of 305 students of both genders in five universities in Chile. The questionnaire included the abbreviated Multidimensional Student&#39;s Life Satisfaction Scale (MSLSS), Satisfaction with Food-related Life Scale (SWFL) and the Subjective Happiness Scale (SHS). Eating habits, frequency of food consumption in and outside the place of residence, approximate height and weight and sociodemographic variables were measured. Using factor analysis, the five-domain structure of the MSLSS was confirmed with 26 of the 30 items of the abbreviated version: Family, Friends, Self, Environment and University. Using cluster analysis four types of students were distinguished that differ significantly in the MSLSS global and domain scores, SWFL and SHS scores, gender, ownership of a...

The aim of this investigation is to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS), in the adult population from ages 18 to 65. In order to do this two studies were conducted. In the first one, we evaluated the internal consistency and construct validation of data from 330 people between 18 and 52 years of age; in the second study, we evaluated the confirmatory factor and validation of data indicators from 1157 people between 18 and 65 years of age. The results show suitable indicators of internal consistency (Cronbach's alpha = 0.82), the exploratory and confirmatory factor analysis finds a one factor's solution. The correlation between the SWLS, the WHOQOL-BREF Quality of Life Questionnaire, and the Difficulties in Emotion Regulation Scale (DERS), display significant, consistent correlations in the expected direction. We conclude that the SWLS is a reliable and valid instrument to use for evaluating the cognitive sphere of subjective well-being in Chile's adult population.

(1) Background: The need to offer brief scales with items that can be answered with few response options is increasingly important in order to be able to access a broad range of the population. The three-item version of Diener's Satisfaction with Life Scale has recently been proposed. The objective of this study is to study the psychometric properties of the three-item version of this Scale with five response options, as well as the measurement invariance by gender, in a Colombian sample; (2) Methods: A confirmatory factor model of the three items of the scale together with the Flourishing Scale has been tested, and the measurement invariance by gender of the model has been studied. The results offer a very satisfactory fit of the model, showing good evidence of construct and criterion validity, good indicators of reliability and measurement invariance by gender; (4) Conclusions: The three-item version of the Life Satisfaction Scale, previously adapted to the Colombian population with five response options, is presented as a valid and reliable measurement tool. In future studies, it would be convenient to study the test-retest reliability, as well as its psychometric properties in different samples and at a cross-cultural level.

Purpose The purpose of this paper is to assess the effect of attitudes towards functional foods (AFF) on university students’ satisfaction with food-related life (SWFL) and to distinguish student typologies, considering that the AFF are not homogeneous among consumers. Design/methodology/approach A survey was applied to 372 university students (mean age=20.4 years, SD=2.4) in Southern Chile. The questionnaire included the AFF questionnaire and the SWFL scale, questions about consumption and knowledge about functional food (FF) and socio-demographic characteristics. Findings Using confirmatory factor analysis (CFA) and structural equation modelling, it was found that AFF directly and significantly influence students’ SWFL. A cluster analysis applied to the Z-scores from the factors obtained by the CFA classified three typologies: positive towards FF (36.3 per cent), moderately positive towards FF (43.0 per cent) and negative towards FF (20.7 per cent). The positive towards FF type ha...
