Introduction
Older people's emotional distress is often related to rumination processes focused on past vital events occurred during their lives. The specific coping strategies displayed to face those events may contribute to explain older adults’ current well-being: they can perceive that they have obtained personal growth after those events and/or they can show a tendency to have intrusive thoughts about those events. This paper describes the development and analysis of the psychometric properties of the Scales for the Assessment of the Psychological Impact of Past Life Events (SAPIPLE): the past life events-occurrence scale (LE-O), ruminative thought scale (LE-R) and personal growth scale (LE-PG).Material and methods
Participants were 393 community dwelling elderly (mean age=71.5 years old; SD=6.9). In addition to the SAPIPLE scales, depressive symptomatology, anxiety, psychological well-being, life satisfaction, physical function and vitality have been assessed.Results
The inter-rater agreement's analysis suggests the presence of two factors in the LE-O: positive and negative vital events. Confirmatory Factor Analysis (CFA) supported this two-dimensional structure for both the LE-R and the LE-PG. Good internal consistency indexes have been obtained for each scale and subscale, as well as good criterion and concurrent validity indexes.Conclusions
Both ruminative thoughts about past life events and personal growth following those events are related to older adults’ current well-being. The SAPIPLE presents good psychometric properties that justify its use for elderly people. 相似文献2.

Background
Xerophilic fungi represent a serious problem due to their ability to grow at low water activities causing the spoiling of low and intermediate moisture foods, stored goods and animal feeds, with the consequent economic losses.Aims
The combined effect of water activity and temperature of four Eurotium species isolated from animal feeds was investigated.Methods
Eurotium amstelodami, Eurotium chevalieri, Eurotium repens and Eurotium rubrum were grown at 5, 15, 25, 37 and 45 °C on malt extract agar adjusted with glycerol in the range 0.710–0.993 of water activities.Results
The cardinal model proposed by Rosso and Robinson (2001) was applied to fit growth data, with the variable water activity at fixed temperatures, obtaining three cardinal water activities (awmin, awmax, awopt) and the specific growth rate at the optimum aw (μopt). A probabilistic model was also applied to define the interface between growth and no-growth. The cardinal model provided an adequate estimation of the optimal aw to grow and the maximum growth rate. The probabilistic model showed a good performance to fit growth/no-growth cases in the predicted range.Conclusions
The results presented here could be applied to predict Eurotium species growth in animal feeds. 相似文献
