Reliability and validity of measuring scale for postoperative complications in third molar surgery.

BACKGROUND: Third molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications. For their measure, in 2014 a previous scale design was presented. The aim of this study was to determine the reliability and validity of a scale designed to measure and quantify postoperative complications in third molar surgery (TMS). METHODS: A cross-sectional study of a measurement model was designed. Sixty-two patients (mean age 20.5 ± 6.6 years; 36 women) underwent TMS in three Chilean hospitals. In the postoperative check-up on the 7th day, a maxillofacial surgeon and a surgical resident performed independent postoperative assessments, applying the scale. A confirmatory factor analysis was conducted to obtain validity, internal consistency, interobserver reliability and a score to categorize the severity of complications using structural equation model analysis. RESULTS: Nine patients (14.5%) had complications. The scale was defined by two components: "Secondary complication" and "Infection" (Cronbach's alpha 0.71; Interobserver reliability 87.7%) and three categories of postoperative complication: "without or mild", "moderate" and "severe". CONCLUSION: This study presents a reliability and validity scale called "Surgical complication assessment scale in TMS".

Longitudinal multigroup invariance analysis of the satisfaction with food-related life scale in university students.

This study examined longitudinal measurement invariance in the Satisfaction with Food-related Life (SWFL) scale using follow-up data from university students. We examined this measure of the SWFL in different groups of students, separated by various characteristics. Through non-probabilistic longitudinal sampling, 114 university students (65.8% female, mean age: 22.5) completed the SWFL questionnaire three times, over intervals of approximately one year. Confirmatory factor analysis was used to examine longitudinal measurement invariance. Two types of analysis were conducted: first, a longitudinal invariance by time, and second, a multigroup longitudinal invariance by sex, age, socio-economic status and place of residence during the study period. Results showed that the 3-item version of the SWFL exhibited strong longitudinal invariance (equal factor loadings and equal indicator intercepts). Longitudinal multigroup invariance analysis also showed that the 3-item version of the SWFL displays strong invariance by socio-economic status and place of residence during the study period over time. Nevertheless, it was only possible to demonstrate equivalence of the longitudinal factor structure among students of both sexes, and among those older and younger than 22 years. Generally, these findings suggest that the SWFL scale has satisfactory psychometric properties for longitudinal measurement invariance in university students with similar characteristics as the students that participated in this research. It is also possible to suggest that satisfaction with food-related life is associated with sex and age.

Eating habits and subjective well-being. A typology of students in Chilean state universities.

The purpose of this study was to distinguish and characterize university student typologies according to their life satisfaction and satisfaction with their food-related life. An online survey was applied between June and August 2013 in five state universities in Chile, to 369 university students (mean age = 20.9 years, SD = 2.27). The survey included the Health-related Quality of Life Index-4 (HRQOL), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life Scale (SWFL), as well as questions about the place of residence, importance of food for well-being, frequency of meals in the place of residence and the frequency of consumption of eight food groups. A cluster analysis was used to determine student typologies. Three typologies of students were distinguished with significant differences in the average scores of the SWLS and SWFL scales, self-perception of health, days with mental health problems, number of days of health-related incapacity, place of residence, socioeconomic status, importance of food for well-being, frequency of breakfast and dinner in the place of residence, frequency of consumption of meat, milk, fruits and vegetables. It was found that most students with higher levels of life satisfaction and satisfaction with food-related life live with their parents, eat at home more frequently, report fewer health problems, have healthful eating habits and consider food very important for their well-being. Although it is necessary to promote or improve the campaigns that foster healthful eating in the entire university population, these campaigns must be specifically targeted to students who do not receive direct support from their families.

Children's perception of food parenting practices: adaptation and validation of the comprehensive feeding practices questionnaire in Chilean adolescents.

Introduction: Assessment of the Comprehensive Feeding Practices Questionnaire in adolescents (CFPQ-Teen) is still limited, with no evaluation of the measurement invariance. The participants comprised 473 Chilean adolescents of both sexes from dual-income nuclear families. The aims of this study were: (1) to adapt to Spanish and validate a model of five-factor version the CFPQ-Teen; (2) to examine the psychometric properties, (3) to evaluate the measurement invariance according to the adolescents' gender; and (4) to compare the scores of each factor between female and male adolescents. Methods: The instrument was translated, back-translated, and adapted from the CFPQ-Teen, confirming the equivalence, conceptual, and face validity in a pilot sample of 40 adolescents. An exploratory factor analysis was performed on the five-factor model of the CFPQ-Teen: Monitoring, Adolescent Control, Restriction for weight control, Parental Modeling, and Environment. The Environment factor was eliminated as a result. Results: The confirmatory factor analysis presented good reliability, convergent, discriminant, and concurrent validity values. In addition, medium to high goodness-of-fit levels were obtained by eliminating an item from the Adolescent Control factor. These results confirm a final 20-item model representing four factors. The multigroup invariance analysis of the measurement model verified configural, metric, scalar, and partial strict invariance. No significant differences were found between females and males in the scores on the four factors. Discussion: These results enable comparisons by sex on the perceptions of Food Parenting Practices from the analyzed factors, primarily within the context of the Chilean sample.

Food neophobia, nanotechnology and satisfaction with life.

This study investigates the relationship between food neophobia, satisfaction with life and food-related life, and acceptance of the use of nanotechnology in food production. Questionnaire data was collected from a sample of 400 supermarket shoppers in southern Chile. The questionnaire measured knowledge of nanotechnology and willingness to purchase food products involving nanotechnology, and included the SWLS (Satisfaction with Life Scale), SWFL (Satisfaction with Food-related Life) and FNS (Food Neophobia Scale) scales. Using cluster analysis, four consumer types were distinguished with significant differences in their scores on the SWLS, SWFL and FNS. The types differed in their knowledge of nanotechnology, willingness to purchase foods involving nanotechnology, age, socioeconomic level and lifestyle. The least food-neophobic type had the highest levels of satisfaction with life and with food-related life and also had the highest acceptance of packaging and foods produced with nanotechnology. The results suggest that the degree of food neophobia is associated with satisfaction with life and with food-related life, as well as with the acceptance of products with nanotechnological applications.

Satisfaction with Food: Profiles of Two-Parent Families with Adolescent Children.

The objectives of this study were to distinguish family profiles based on the level of satisfaction with food-related life (SWFoL) of mothers, fathers, and adolescents, and to characterize the profiles based on the three family members' diet quality and nutritional status, family's eating habits, parental feeding practices, parent's nutritional knowledge, and sociodemographic characteristics. Questionnaires were applied to a sample of 300 two-parent families with adolescent children, aged between 10 and 17 years, in Temuco, Chile. The questionnaires used were: satisfaction with food-related life (SWFoL); adapted healthy eating index (AHEI); family eating habits questionnaire (FEHQ); and the nutritional knowledge subscale. They also answered questions about eating habits and provided data to determine BMI and sociodemographic characteristics. Four different profiles were identified with respect to SWFoL: "Families satisfied with their food" (50.6%); "Fathers and mothers moderately satisfied with their food, children satisfied" (23.2%); "Families extremely satisfied with their food" (16.6%); and "Fathers and mothers satisfied with their food, children extremely dissatisfied" (9.7%). The profiles demonstrated heterogeneity in SWFoL. Higher levels of SWFoL (mothers, fathers and adolescents) were associated with healthier eating habits. These results contribute to new studies that enable understanding of how families' healthy eating habits are part of improving quality of life.

School engagement profiles in Chilean secondary students.

School engagement is considered a key variable in promoting educational trajectories. Previous research shows that maintaining high levels of school engagement is fundamental, given its association with multiple academic results and lower-risk behaviors. This article aims to show how school engagement profiles (based on the behavioral, affective, and cognitive subdimensions) relate to academic achievement (math and language), contextual factors (family, teachers, and peer support), and gender. This study involved 527 students enrolled in the 1st year of secondary education in public schools in Chile. All students came from vulnerable schools. Our study used cluster analysis to identify students' profiles. We identified the existence of three different profiles of school engagement (high, medium, and low) considering the three subdimensions of school engagement (behavioral, affective and cognitive). Secondly, ANOVA analysis showed differences in language and math academic achievement scores between the profiles, where higher engagement students showed higher academic performance in language and math. These findings are consistent with previous studies showing that contextual factors strongly influence school engagement and better behavioral engagement in female than male students. It will discuss the pertinence of person-centered approaches focusing on combinations of variables within students rather than taking each variable as the focal point when analyzing goals. These techniques are a favorable methodological alternative to investigate why some students have better results than others instead of just ranking students by their performance. It will conclude with some future lines of research and practical implications.

Measurement invariance of the comprehensive feeding practices questionnaire in dual-earner parents with adolescent children in Chile.

The Comprehensive Feeding Practices Questionnaire (CFPQ) has been evaluated in international studies, but the evaluation of its psychometric properties in Spanish, and in particular for parents of adolescents is still limited, and the invariance of measurement according to gender has not been evaluated. Therefore, the objectives of this study were: (1) To adapt the five-factor model of the CFPQ instrument to Spanish; (2) To examine the psychometric properties of this adaptation; and (3) To evaluate the measurement invariance of the model to verify the equivalence of measurement of the perceptions of food parenting practices between mothers and fathers belonging to nuclear, dual-earner families with adolescent children. Participants were 946 mothers and fathers from Southern Chile. Results showed that the conceptual equivalence for the CFPQ was achieved. An exploratory factor analysis was performed for a five-factor model: Monitoring, Child control, Restriction for weight control, Modeling and Environment. Horn's parallel analysis identified four factors, while factor loading analysis determined the removal of the environment factor. Confirmatory factor analysis presented good reliability values. Convergent and discriminant validity was confirmed, and medium-to-high levels of goodness of fit were obtained, eliminating two items. Results supported a final model of four factors and 19 items. Multigroup analysis of the measurement model verified the configural and metric invariance between fathers and mothers, while the scalar and strict partial invariance was verified. These findings are a relevant guide to measure factorial scores in the four-factor model of the CFPQ, establishing a characterization of feeding practices of parents and adolescents.

A study of the relationship between degree of ethnocentrism and typologies of food purchase in supermarkets in central-southern Chile.

The objective of this study was to distinguish different types of consumers according to their level of ethnocentrism in relation to the consumption of foodstuffs in central-southern Chile. To do this a modification of the CETSCALE (Consumer Ethnocentric Tendencies Scale) was applied through direct survey of 800 habitual supermarket shoppers in two cities in central-southern Chile. The modified CETSCALE presented a sufficient level of internal consistency and there were three factors which included the 17 items of the scale. Five typologies of consumer with different degrees of ethnocentrism were distinguished by cluster analysis, based on the values of the factors and items in the CETSCALE. The composition of the typologies of consumers were related to the city and zone of residence, age, socioeconomic level, self-declared life-style, ethnic origin, knowledge of the origin of the foodstuffs purchased, frequency of purchase of imported foodstuffs and reasons for rejection in the case of a low purchase frequency. It may therefore be concluded that different levels of ethnocentrism exist in the consumption of foodstuffs, related with some socio-demographic characteristics of consumers and their attitudes to imported foodstuffs.

[Food satisfaction in Mapuche persons in the Metropolitan Region of Santiago, Chile]. / Satisfacción con la alimentación en personas Mapuche en la Región Metropolitana de Santiago, Chile.

Although the study and measurement of satisfaction with life has generated great interest in the last 15 years, there are few works which address satisfaction with food-related life. In order to identify variables which have an influence on satisfaction with food-related life among Mapuche persons, a survey was applied to 400 Mapuche subjects in the Santiago Metropolitan Region, Chile. The scales evaluated in the questionnaire included: SWFL (Satisfaction with Food-related Life), lifestyles, food, and Mapuche acculturation. It was found that 41.0% were extremely satisfied, 40.5% satisfied, 17.2% somewhat satisfied and 1.2% dissatisfied with their food-related life. To identify variables which have an influence on satisfaction with food, an ordinal multinomial logit model was proposed, which was significant (p < 0.01) as a whole. The probability of high satisfaction with food-related life increases as there are fewer children in the household, the person's expenditure on food increases, the person consumes some Mapuche foods, is aged 55 or more, consumes red meat in moderation, consumes foods without additives, try to balance work and private life, does not read the labels of products, and if he/she had Mapuche friends at school. Thus satisfaction with food-related life in Mapuche persons in the Metropolitan Region is related to demographic variables, expenditure on food, consumption of Mapuche foods and life-style.

[Acceptance of yoghurt with different functional ingredients among consumers in supermarkets in southern Chile]. / Aceptación hacia yogurt con diferentes ingredientes funcionales en consumidores de supermercados del sur de Chile.

In view of the interest in the role of foodstuffs in improving wellbeing and health, the object of this study is to distinguish consumer typologies in Temuco, La Araucanía Region, Chile, according to their preferences for different functional ingredients, flavouring, colouring and price in yoghurt. A semi-structured survey was applied to 400 supermarket customers. The respondents ordered eight alternative yoghurts according to their preferences, with different functional ingredients (fibre, antioxidants), flavourings (sugar, sweetener), colouring (natural, artificial) and three price options, for a conjoint analysis with fractional factorial design. Variables affecting knowledge of "functional food" were evaluated using a binomial logit model. It was determined by conjoint analysis that in general a preference existed for yoghurt containing fibre, sweetener, natural colouring, and at the lowest price. Three typologies were distinguished by analysis of hierarchical conglomerates: the majority segment (48.8%) displayed a greater preference for fibre; the second (41.7%) also preferred fibre, but gave first priority to artificial colouring and preferred a higher price. The minority (9.5%) was the only segment to prefer antioxidants. The typologies differed significantly in satisfaction with their food-related life, knowledge of the function of fibre and presence of cancer and obesity in some member of the respondent's family. The binomial logit model was significant (P < 0.01), indicating that if the consumer has a job or has had access to information on functional foods, the probability increased of knowledge of what these mean. There was thus majority acceptance of yoghurt enriched with fibre and with added sweetener.

Psychometric Analysis of a School Social Climate Scale: Input Elements for the Investigation and Promotion of Well-Being.

School social climate from a multidimensional perspective is a focus of great interest in international research and educational and well-being public policies due to the high prevalence of interpersonal violence in adolescents, currently considered a global public health problem. The object of the present study was to assess the psychometric measurement capacity of a set of items to evaluate school social climate in the Student Context Questionnaire of the Chilean Education Quality Measurement System. The sample analyzed consisted of second-year high school students who replied to a Student Context Questionnaire in 2015 (n~158,572). Exploratory and confirmatory factorial analyses were carried out in a measurement model to identify the presence of constructs and items of high homogeneity. The results showed an acceptable to a good fit in the final model, which consisted of 15 latent constructs, and also showed invariance for school administrative dependencies and invariance for sex. All the above implies a contribution to the public organisms that create standardized tests along with the investigation in compulsory secondary education measurement to prevent future violent behaviors, contribute to reducing interpersonal violence, and improve the well-being of the educational community.

An Ecological, Participatory, Integral and Contextualized Model (EPIC Model) of Family-School Connection: A Preliminary Analysis.

There are several programs that aim to strengthen the bond between families and schools that have shown a positive impact on this relationship as well as its effectiveness in improving academic and socioemotional child indicators. Most of the studies in this area come from Anglo-Saxon countries while in Latin America research is still scarce. Thus, this study aims to assess the influence of implementing an Ecological, Participatory, Integral and Contextualized Family-School Collaboration Model (EPIC) on family involvement, social-emotional development, and cognitive test outcomes in children in elementary school. Three possible hypotheses have been considered: (1) The EPIC Family-School Collaboration Model will have a positive and significant influence on the level of family involvement; (2) The EPIC Family-School Collaboration Model will have a positive and significant influence on the results of some cognitive tests; and; (3) The EPIC Family-School Collaboration Model will have a positive and significant influence on child social-emotional development. The study included 171 students who attended second and third elementary grades in schools in Chile during 2017 and fourth and fifth grades during 2019. The children were between 7 and 12 years old (M = 8.17, SD = 0.98), during 2017 and between 9 and 14 years old (M = 9.88, SD = 0.99), during 2019. The results show that the EPIC Family-School Collaboration Model has a positive and significant influence on the level of home-based involvement, memory and attention and intrapersonal skills in the first cycle of elementary education.

[Differences in food consumption associated with ethnic group and acculturation in the Metropolitan Region of Santiago, Chile]. / Diferencias étnicas y de aculturación en el consumno de alimentos en la Región metropolitana de Santiago, Chile.

In order to identify differences in the food consumption and expenditure habits of Mapuches according to their ethnic group as consumers as well as their degree of acculturation, a personal survey was conducted on 400 people stratified by ethnic group in four districts of the Metropolitan Region of Santiago, Chile. The empirical results showed that habits regarding the consumption of food groups included in the Family Budget Survey did not present any significant differences depending on the consumer's ethnic group, although the monthly expenditure on food is lower in Mapuche households. The ethnic origin and degree of acculturation in Mapuches are only significantly associated with the consumption of mate (herbal infusion) and food in restaurants. Mapuches maintain both food practices belonging to their traditional culture as well as foods incorporated more recently, such as mate. The degree of acculturation is significantly associated with the consumption of these foods; bi-cultural Mapuches present a higher probability of consuming a greater range of traditional foods than accultured Mapuches.

Influence of Family Involvement and Children's Socioemotional Development on the Learning Outcomes of Chilean Students.

There is an extensive body of evidence to support both family involvement and students' socioemotional development as key factors in the promotion of learning outcomes. However, there is insufficient evidence to establish exactly what this impact is when both factors are considered simultaneously. Therefore, the aim of this study is to analyze the influence of family involvement and socioemotional development on learning outcomes of Chilean students, identifying the structure that most correctly identifies the influence of the predictor variables (family involvement and socioemotional development) on learning outcomes. We present the following three hypotheses that consider possible basic interrelation structures: (1) The influence of family involvement on learning outcomes is mediated by students' socioemotional development (mediation hypothesis); (2) The influence of family involvement on learning outcomes is moderated by students' socioemotional development (moderation hypothesis); (3) Family involvement and students' socio emotional development directly affect learning outcomes (covariance hypothesis). The structures were evaluated by means of a structural equation model analysis. The study included 768 students who attended second and third elementary grades in Chilean schools. The children were between 7 and 11 years old (M = 8.29, SD = 0.86); 41.3% were girls and 58.7% were boys. The results show that family involvement and students' emotional development directly affect learning outcomes (CFI = 0.995, TLI = 0.993, RMSEA = 0.016). From the results, we can conclude that the data support the hypothesis that both family involvement and socioemotional development are predictors of learning outcomes, thereby rejecting that the impact of family involvement on learning outcomes is mediated or moderated by socioemotional development.

Food neophobia, life satisfaction and family eating habits in university students.

The aim of this study was to categorize university students based on their association between food neophobia and levels of subjective well-being, in general and in the food domain, and their perception of their family's eating habits. A survey was conducted among 372 university students from southern Chile. The questionnaire included the Food Neophobia Scale (FNS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL), Health-related Quality of Life Index (HRQOL-4), and Family Eating Habits Questionnaire (FEHQ). Three student types were distinguished by cluster analysis: Group 1 (26.9%) had the highest scores on the FNS, SWLS and SWFL. Group 2 (40.8%) had a high score on the FNS but the lowest scores on the SWLS and SWFL. Group 3 (32.3%) had the lowest FNS score and high scores on the SWLS and SWFL. Group 2 stood out in having a low score on the FEHQ's component for cohesiveness of family eating. These results suggest that both neophobic and non-neophobic students have positive levels of satisfaction with life and food-related life, and that satisfaction among neophobic students is related to family eating patterns, especially cohesiveness in family eating.

Dietary restraint and self-discrepancy in male university students.

Self-discrepancy describes the distance between an ideal and the actual self. Research suggests that self-discrepancy and dietary restraint are related, causing a significant impact on the person's well-being. However, this relationship has been mostly reported in female and mixed populations. In order to further explore dietary behaviors and their relations to self-discrepancy and well-being-related variables in men, a survey was applied to a non-probabilistic sample of 119 male students from five Chilean state universities (mean age=21.8, SD=2.75). The questionnaire included the Revised Restraint Scale (RRS) with the subscales weight fluctuations (WF) and diet concern (DC), the Satisfaction with Life Scale (SWLS), the Satisfaction with Food-Related Life Scale (SWFL), the Nutrition Interest Scale (NIS), and the Self-discrepancy Index (SDI). Questions were asked about socio-demographic characteristics, eating and drinking habits, and approximate weight and height. A cluster analysis applied to the Z-scores of the RRS classified the following typologies: Group 1 (22.7%), men concerned about weight fluctuations; Group 2 (37.0%), men concerned about diet and weight fluctuations; Group 3 (40.3%), unconcerned about diet and weight fluctuations. The typologies differed in their SDI score, restriction on pastry consumption and reported body mass index (BMI). Students with higher DC and WF scores had a higher BMI, and tended to report high self-discrepancy not only on a physical level, but also on social, emotional, economic and personal levels. This study contributes to the literature on subjective well-being, dietary restraint and self-discrepancy in men from non-clinical samples.

Analyzing Food-Related Life Satisfaction and other Predictors of Life Satisfaction in Central Chile.

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, self-reported number of days affected by mental health problems, frequency of supper with the family, the degree of agreement with respect to family being an important source of happiness (p < .05); and family size and frequency of food consumption in fast food outlets (p < .10). Satisfaction with life in the study sample is related to aspects associated with health, family and eating, and the family interaction associated with eating may play an important role in overall satisfaction with life.

Relationship between the domains of the Multidimensional Students' Life Satisfaction Scale, satisfaction with food-related life and happiness in university students.

AIM: To characterize types of university students based on satisfaction with life domains that affect eating habits, satisfaction with food-related life and subjective happiness. MATERIALS AND METHODS: 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'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. RESULTS: 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 food allowance card funded by the Chilean government, importance attributed to food for well-being and socioeconomic status. CONCLUSIONS: Higher levels of life satisfaction and happiness are associated with greater satisfaction with food-related life. Other major life domains that affect students' subjective well-being are Family, Friends, University and Self. Greater satisfaction in some domains may counterbalance the lower satisfaction in others.

Objetivo: caracterizar tipologías de estudiantes universitarios según la satisfacción en dominios de la vida que afectan a los hábitos alimentarios, satisfacción con la alimentación y nivel de felicidad subjetiva. Material y método: se aplicó un cuestionario a una muestra no probabilística de 305 estudiantes de ambos géneros de cinco universidades de Chile. El cuestionario incluyó: Escala Multidimensional de Satisfacción con la Vida para Estudiantes (MSLSS) abreviada, Satisfacción con la Alimentación (SWFL) y la Escala de Felicidad Subjetiva (SHS). Se consultaron hábitos de consumo de alimentos, frecuencia de comidas dentro y fuera del lugar de residencia, peso y estatura aproximada y variables sociodemográficas. Resultados: mediante análisis factorial se confirmó la estructura de cinco dominios de la MSLSS, con 26 de los 30 ítems de la versión abreviada: Familia, Amigos, Sí mismo, Entorno de vida y Universidad. Mediante análisis clúster se distinguieron cuatro tipologías que difirieron significativamente en los puntajes de los dominios de la MSLSS y en su puntaje global, en los puntajes de la SWFL, SHS, género, contar con una tarjeta de alimentación financiada por el Estado chileno, importancia asignada a la alimentación para el bienestar personal y nivel socioeconómico. Conclusiones: mayores niveles de satisfacción con la vida y de felicidad se asocian con una mayor satisfacción con la alimentación. Otros dominios importantes que afectan al bienestar subjetivo de los estudiantes corresponden a la familia, los amigos, la universidad y el sí mismo. La mayor satisfacción en unos dominios compensaría la menor satisfacción en otros.

Dietary restraint and subjective well-being in university students in Chile.

OBJECTIVE: To characterize university students typologies according to chronic food restriction, satisfaction with life and food consumption. MATERIALS AND METHOD: A questionnaire was applied on a non-probability sample of 369 male and female students from five Chilean universities. The questionnaire included: Revised Restraint Scale (RRS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL) and the Health-related Quality of Life Index. The survey included food and drink consumption habits, weight and approximate height and sociodemographic variables. RESULTS: Two factors in the RRS were detected by exploratory factor analysis: Preoccupation with Diet (PD) and Weight fluctuations (WF). A confirmatory factor analysis validated the bifactor structure of the RRS with an acceptable adjustment kindness. The cluster analysis allowed a distinction of four typologies with a significant variation in PD, WF, SWLS and SWFL scoring, number of days with mental health problems, frequency of alcoholic drinks consumption, restraint on the consumption of certain foods, drinks and spices, consumption frequency of fruit out of the main meals and types. Typologies did not differ on their body mass index. CONCLUSIONS: Both, students preoccupied with diet and those who are not, experience higher levels of satisfaction with life and with food. Lower levels of global life satisfaction and satisfaction with food are related with the fluctuations in weight.

Objetivo: Caracterizar tipologías de estudiantes universitarios según restricción alimentaria crónica, satisfacción con la vida y con la alimentación. Material y método: Se aplicó un cuestionario a una muestra no probabilística de 369 estudiantes de ambos géneros de cinco universidades de Chile. El cuestionario incluyó: Escala Revisada de Restricción Alimentaria (RRS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL) y el Índice de Calidad de Vida relativo a la Salud. Se consultaron hábitos de consumo de alimentos y bebidas, peso y estatura aproximada y variables sociodemográficas. Resultados: Mediante análisis factorial exploratorio se detectaron dos factores en la RRS: Preocupación por la Dieta (PD) y Fluctuaciones de Peso (FP). Mediante análisis factorial confirmatorio se validó la estructura bifactorial de la RRS con una aceptable bondad de ajuste. Mediante análisis clúster se distinguieron cuatro tipologías que difirieron significativamente en los puntajes de PD y FP, los puntajes de la SWLS y SWFL, número de días con problemas de salud mental, frecuencia de consumo de bebidas alcohólicas, restricción del consumo de algunos alimentos, bebidas y condimentos, frecuencia de consumo de fruta a deshora y género. Las tipologías no difirieron en su índice de masa corporal. Conclusiones: Tanto los estudiantes que se preocupan por la dieta como los que no, experimentan mayores niveles satisfacción con la vida y con su alimentación. Menores niveles de satisfacción global y en el dominio de la alimentación se relacionan con las fluctuaciones de peso.
