A path analysis model of self-rated health among older people.

1999

The aim of this study was to examine the structure of self-rated health among 75-year-old men and women. The study was part of the Evergreen project, comprising all the 75-year-old residents (N = 382) of Jyväskylä, in central Finland, in 1989. The data were collected by interviews, questionnaires and laboratory examinations, focusing on different domains of health and functional capacity. Of the target group, 91.6% (119 men and 231 women) participated in the interview, and 77.2% (104 men and 191 women) took part in the clinical and laboratory examinations. Path analysis models (LISREL 8) were used to examine the structure of self-rated health. About half the participants self-rated their he…

Quality of Life and Barriers in the Urban Outdoor Environment in Old Age

2010

OBJECTIVES: To examine the association between barriers in the outdoor environment and perceived quality of life (QoL) in old age and to assess whether fear of moving outdoors and unmet physical activity need contribute to this association. DESIGN: Cross-sectional. SETTING: Community and research center. PARTICIPANTS: Five hundred eighty-nine, community-dwelling people aged 75 to 81 took part in face-to-face home-interviews and examinations in the research center. MEASUREMENTS: QoL was assessed using the LEIPAD questionnaire. Environmental barriers were studied based on self-reports of lack of resting places or long distances (distances), noisy traffic or dangerous crossroads (traffic), and…

Disability, physical activity, and muscle strength in older women: The women's health and aging study

1999

Abstract Objective: To study associations of motor disability, physical activity, and muscle strength in older women, in particular to investigate whether model of spiraling decrease is expressed in the data. Design: Cross-sectional analysis using data from the base-line measurements of The Women's Health and Aging Study (WHAS). Setting: Participants' homes. Participants: A total of 1,002 disabled women aged 65 years and older living in the community. Outcome Measures: Motor disability was measured by the number of self-reported difficulties in grasping, lifting 101b, walking across a small room, walking 14 mile, climbing 10 steps, and doing heavy housework. Level of physical activity was d…

OBJETIVO: Avaliar a validade fatorial e de construto da versão brasileira do "Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo" (CESQT). MÉTODOS: O processo de versão do questionário original do espanhol para o português incluiu as etapas de tradução, retrotradução e equivalência semântica. Foi realizada análise fatorial confirmatória e utilizados modelos de equações estruturais de quatro fatores, similar ao da estrutura original do CESQT. A amostra foi constituida de 714 professores que trabalhavam em instituições de ensino da cidade de Porto Alegre, RS, e região metropolitana 2008. O questionário possui 20 itens distribuídos em quatro subescalas: Ilusão pelo trabalh…

The Relationship Between Generalized Resistance Resources, Sense of Coherence, and Health Among Finnish People Aged 65-69

2005

Abstract. The present study investigated the appropriateness of Antonovsky's model, in which generalized resistance resources (GRRs) facilitate an individual's sense of coherence (SOC); which in turn is assumed to sustain health. The proposed model was tested using a sample of 320 Finnish persons (132 of them were men and 188 women) aged 65-69 years. The GRRs investigated were family income, cognitive functioning, years of formal education, marital status, and physical exercise. Health was measured by means of a multidimensional indicator composed of physical, social and mental health. Structural Equation Modelling (SEM) within the framework of LISREL models were used to test the hypothesi…

Home atmosphere and adolescent future orientation

1990

Adolescent future orientation was studied from the point of view of orienting expectations about the future, consisting of three aspects: cognitive (clarity of plans for the use of future time), affective (optimistic vs pessimistic attitudes toward the future), and motivational (realistic vs unrealistic wishes for the future). The study was part of the Jyvaskyla Longitudinal Study of Social Development, the original sample for which consisted of 8-year-old subjects. Follow-up studies were made using a semistructured interview covering several aspects of home atmosphere (child-rearing and external home conditions) and youthful life orientation at ages 14 and 20 with 115 subjects. Results obt…

Factorial validity of the Maslach Burnout Inventory (MBI-HSS) among Spanish professionals

2005

OBJECTIVE: To assess the factorial validity and internal consistency of the Maslach Burnout Inventory (MBI-HSS). METHODS: In a sample consisting of 705 Spanish professionals from diverse occupational sectors (health, education, police and so one), seven plausible factorial models hypothesized were compared using LISREL 8. RESULTS: The four-factor oblique solution and the three-factor oblique solution showed the best and similar fit. Deletion of Item 12 and Item 16, taking into consideration the suggestions in the manual, improved the goodness of fit for both models. The four-factor oblique model suggests that, in addition to Emotional Exhaustion (EE) and Depersonalization (DP), Personal Acc…

A Cautionary Note on Incremental Fit Indices Reported by LISREL

2005

Abstract. Incremental fit indices (IFIs) are regularly used when assessing the fit of structural equation models. IFIs are based on the comparison of the fit of a target model with that of a null model. For maximum-likelihood estimation, IFIs are usually computed by using the χ2 statistics of the maximum-likelihood fitting function (ML-χ2). However, LISREL recently changed the computation of IFIs. Since version 8.52, IFIs reported by LISREL are based on the χ2 statistics of the reweighted least squares fitting function (RLS-χ2). Although both functions lead to the same maximum-likelihood parameter estimates, the two χ2 statistics reach different values. Because these differences are especi…

Sense of coherence and work characteristics: A cross-lagged structural equation model among managers

2004

This study investigated the dominance of predictive relationships between Sense of Coherence (SOC) and work characteristics (organizational climate and job control) in cross-lagged longitudinal data with two measurement points and a time lag of 3 years. The sample consisted of 615 (587 men and 28 women) managers, aged between 27 and 64 years. The cross-lagged longitudinal analysis was done by the use of Structural Equation Modelling (SEM) within the framework by LISREL. The results of the chi-square difference tests indicated that the model where SOC at Time 1 predicted work characteristics at Time 2 better accounted for the data than the competitive models. However, the only significant pa…
