The effect of social support on the emotional well-being of people with amyotrophic lateral sclerosis: Exploring the mediating role of spirituality

OBJECTIVES

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that, so far, is considered always fatal. Treatments mainly consist in increasing survival and aim to improve the quality of life of people with ALS (pwALS). Social support and spirituality have been shown to play a key role in pwALS' quality of life. Our study explored it in depth by investigating the underlying mechanisms linking social support, spirituality, and emotional well-being.

METHODS

Thirty-six pwALS underwent a battery of tests evaluating emotional well-being (emotional well-being scale of the 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire), social support (6-item Social Support Questionnaire), and spiritual well-being (12-item Functional Assessment of Chronic Illness Therapy - Spiritual well-being). Our recruitment was web-based through the FILSLAN and the ARSLA websites as well as through Facebook® advertisements (ALS groups). Data were analyzed by Pearson correlation analysis and Process macro was used in an SPSS program to analyze the mediator variable effect.

RESULTS

Availability of social support, spiritual well-being, and 2 of its dimensions, i.e., meaning and peace, were positively correlated with emotional well-being. The mediational analyses showed that spiritual well-being, meaning, and peace act as mediators in the association between availability of social support and good emotional well-being.

SIGNIFICANCE OF RESULTS

Availability of social support and spirituality are essential for the emotional well-being of pwALS. Spirituality as a mediator between availability of social support and emotional well-being appears as real novel finding which could be explored further. Spiritual well-being, meaning, and peace appear as coping resources for pwALS. We provide practical guidance for professionals working with pwALS.

Profiles of well-being in French older adults and associations with successful aging and personality: findings from the SHARE project

Maintaining the well-being of the older adults is a primary concern in gerontology. This study determined different profiles of well-being (WB) and compared the profiles in terms of successful aging (SA), personality, and sociodemographic variables. The study sample consisted of 856 adults aged 65-98 years. WB was taken into account in an eudemonic and hedonic approach. SA was measured by assessing the three distinct components of Rowe and Kahn's model (Successful aging. Gerontol 37(4):433-440. 10.1093/geront/37.4.433, 1997), personality by the Big Five Inventory, and sociodemographic variables. Latent class analyses (LCA) determined the number of WB profiles, and ANOVAs and Chi2 tests to compare them. The LCA revealed three WB profiles: Profile 1 (9.35%, n = 80), Profile 2 (37.38%, n = 320), and Profile 3 (53.27%, n = 456) in which participants reported lower, intermediate, and higher WB scores. Our results confirm that a high level of WB (Profile 3) can be linked to the components of SA and socio-demographic characteristics (age, marital status, level of education, income). This raises questions about the injunctions concerning healthy aging that older people integrate. It's also interesting to note that the intermediate profile (profile 2) can be either close to the "lower WB" profile (Profile 1) in terms of openness, conscientiousness, and agreeableness or to the "higher WB" profile (Profile 3) in terms of extraversion. However the three profiles do not have the same level of neuroticism. These results also showed the importance of adapting the support offered to older people according to their health status and/or individual characteristics.

Implementation of equine-assisted intervention for older adults with Alzheimer's disease residing in a nursing home: Brakes and levers

OBJECTIVE

Although research on equine-assisted intervention (EAI) for older adults is beginning to be published, no scientific study has examined the various elements that can limit or facilitate the implementation of EAI with older adults suffering from Alzheimer's disease (AD) residing in nursing homes. The aim of this study was to identify the possible brakes and levers of implementing EAI with AD patients. A focus on professional affiliation was conducted.

METHOD

The survey was posted online on 2 February 2021 via the Sphinx software. As this study was aimed at gerontology professionals working in nursing homes, they were contacted through various specialized social networks. A total of 663 people answered the survey.

RESULTS

The results indicate that for 45% of the participants, the main brake to implementing EAI is related to the institutional burden. As for the levers, 29% of the people indicated that it would mainly be beneficial due to the cognitive stimulation that EAI would provide. People who were not familiar with EAI reported more brakes to its implementation. Finally, it was observed that the caregivers were those who put forward the most levers for the implementation of EAI with AD patients living in nursing homes.

CONCLUSION

Thus, this study allows us to understand some of the reasons why nursing homes are reluctant to set up EAI. Communication on this subject is currently a lever to be developed.

IMPLICATIONS FOR PRACTICE

By highlighting the brakes and levers on the implementation of EAIs, we are able to identify suitable guidelines for developing this type of intervention in nursing homes, which could be used as a complement to nursing care to help Alzheimer's patients overcome physical or psychological health problems.

Bridging the Gap between Research and the Community: Implementing Physical and Cognitive Interventions to Improve Spontaneous Walking Speed in Older Adults

The application of interventions to enhance mobility in ecological settings remain understudied. This study was developed to evaluate the feasibility of training methods in a community centre and to evaluate their impact on mobility outcomes. Fifty-four participants were randomized to one of three 12-week training programs (three times/week): aerobic (AE), gross motor abilities (GMA) or cognitive (COG). Feasibility was evaluated by calculating adherence, feedback from participants and long-term participation. The impact of these interventions on mobility was assessed by comparing pre- and post-program on Timed-up-and-go (TUG) and spontaneous walking speed (SWS) performances. Results showed relatively high rates of adherence (85.1%) and long-term participation (66.7%), along with favorable feedbacks. SWS significantly improved in COG (0.10 ± 0.11 m.s^-1; p = 0.004) and AE (0.06 ± 0.11 m.s^-1; p = 0.017) groups, and TUG performance was maintained in all groups. Results of this feasibility study demonstrated successful implementation of physical and cognitive training programs, encouraging the development of real-world applications.

Associations Between Frailty and Inflammation, Physical, and Psycho-Social Health in Older Adults: A Systematic Review

Frailty is a complex geriatric syndrome with multifactorial associated mechanisms that need to be examined more deeply to help reverse the adverse health-related outcomes. Specific inflammatory and physical health markers have been associated with the onset of frailty, but the associations between these factors and psycho-social health outcomes seem less studied. This systematic review aimed to identify, in the same study design, the potential associations between frailty and markers of inflammation, and physical or psycho-social health. A literature search was performed from inception until March 2021 using Medline, Psycinfo, and EMBASE. Three raters evaluated the articles and selected 22 studies, using inclusion and exclusion criteria (n = 17,373; 91.6% from community-dwelling samples). Regarding biomarkers, 95% of the included studies showed significant links between inflammation [especially the higher levels of C-reactive protein (CRP) and interleukin-6 (IL-6)], and frailty status. Approximately 86% of the included studies showed strong links between physical health decline (such as lower levels of hemoglobin, presence of comorbidities, or lower physical performance), and frailty status. At most, 13 studies among the 22 included ones evaluated psycho-social variables and mixed results were observed regarding the relationships with frailty. Results are discussed in terms of questioning the medical perception of global health, centering mostly on the physical dimension. Therefore, the development of future research studies involving a more exhaustive view of frailty and global (bio-psycho-social) health is strongly encouraged.

Prevalence of malnutrition risk among older French adults with culinary dependence

OBJECTIVE

The term 'culinary dependence' denotes a situation in which someone delegates all or part of their daily meal-related activities to a third party. The present study aimed to explore nutritional risk among older people (≥65 years) with culinary dependence.

METHOD

The first survey included 559 people either living at home without help, with help unrelated to food activities, with help related to food activities or living in nursing home. The second survey included 319 people with food help provided by a caregiver, by meals-on-wheels or by a nursing home. Nutritional status was assessed with the Mini-Nutritional Assessment. Sociological background and wellness variables (health, cognitive and mental status) were collected.

RESULTS

The first survey found a strong association between culinary dependence and nutritional risk. About half of the people who delegated their food-related activities were malnourished or at risk of malnutrition compared with only 4% for people with no help and 12% for people with help unrelated to food activity. According to the second survey, this prevalence varied slightly depending on who the tasks were delegated to (46% for those who had the support of a caregiver; 60% for those who used a meals-on-wheels service; 69% for those living in nursing home). According to multivariate analyses, dependence categories, depressive symptoms and cognitive status were identified as independent determinants of malnutrition.

CONCLUSION

Without inferring a causal relationship between dependence and malnutrition, there is a strong need for care structures to take into account the issue of malnutrition when developing services targeting older people.

Validation of the Revised Collett-Lester Fear of Death Scale in a French Population

Death and dying are processes that every human being encounters in his or her lifetime and perhaps the greatest loss an individual can suffer. In this sense, fear of death is regarded as a risk and maintaining factor of psychopathology. As such, effective and efficient measurement of this construct becomes a priority. While the Revised Collett-Lester Fear Of Death Scale (CL-FODS) is a brief, commonly used assessment, such a tool is lacking in French clinical practice. The present study aimed to adapt the revised CL-FODS in a general French sample and to determine its psychometric properties, namely its factorial structure, concurrent and convergent validity, and internal consistency. A sample of 590 participants responded to the French revised CL-FODS, as well as three instruments assessing death anxiety (DAS), neuroticism and spirituality (FACIT-Sp), to examine the internal consistency, validity and factorial structure of the scale. Both exploratory and confirmatory factor analysis confirmed a four-factor model: (1) One’s Own Death,” (2) The Death of Others, (3) The Dying of Others, and (4) One’s Own Dying. Five items did not load on these four factors, suggesting that the revised CL-FODS might require further psychometric refinement. The revised CL-FODS showed good internal consistency. The scale was found to be significantly associated with the Death Anxiety Scale. When the appropriate psychometric characteristics are taken into account, this scale can be used in clinical and research settings to assess death concerns in French society.

Food perception, lifestyle, nutritional and health status in the older people: Typologies and factors associated with aging well

The aging process is associated with physiological, sensory, psychological, and sociological changes likely to have an impact on food intake and the nutritional status. The present study aimed to explore the heterogeneity of the French older population (>65 years old) using a multidisciplinary approach. More specifically, the study aimed to highlight different typologies (i.e. clusters of individuals with similar characteristics) within the older population. We conducted face-to-face interviews and tests with 559 French older people, recruited from different categories of dependency (at home without help, at home with help, in nursing homes). Clustering analysis highlighted seven clusters. Clusters 1-3 contained 'young' older people (<80) with a good nutritional status; these clusters differed according to food preferences, the desire to have a healthy diet, or interest in food. Clusters 4-7 mainly contained 'old' older people (80+), with an increase in the nutritional risk from cluster 4 to cluster 7. Two of these clusters grouped healthy and active people with a good level of appetite, while the two other clusters were associated with a clear decline in nutritional status, with people suffering from eating difficulties or depression. The results raise the need to develop targeted interventions to tackle malnutrition and implement health promotion strategies among the seniors.

Brakes and levers to implement an animal-assisted intervention in nursing homes: Preliminary study

BACKGROUND

Increasing numbers of scientific studies have dealt with the benefits of animal assisted intervention programs (AAI). Although many positive effects have been identified, there are still few AAI programs in nursing homes. To date, no study has investigated special the difficulties in implementing such a program. The aim of this study was to explore the representations of this type of program among caregivers.

METHODS

This qualitative study was conducted between January and June 2019. Psychologists conducted 11 interviews with people working in nursing homes. The sample was based on different professions and on the fact that participants had already been involved in an IAA program.

RESULTS

The results were organized according to two main themes: brakes and levers. The results show that the brakes were raised quickly before the implementation of the project, but once the project had been implemented, the perceived beneficial effects multiplied and all those interviewed mentioned the benefits of animals. More than half of the caregivers interviewed mentioned animals as a lever, facilitating contact with elderly people suffering from dementia. Setting up a project upstream enhanced the success of this type of program.

CONCLUSION

The benefits perceived by the people interviewed are consistent with the scientific literature. The obstacles mentioned for implementing this type of program can be reduced by a rigorous and well-thought-out project.

Change of depressive symptoms in a French nine-year longitudinal study of aging: Gender differences and relationships between social support, health status and depressive symptoms

OBJECTIVES

The aims of this study were to examine the trajectory of depressive symptoms among older French people, to investigate the role of gender in the developmental trajectory of depressive symptoms and to explore whether the linear increase in depressive symptoms might be accentuated or attenuated at time points during which the older adults' scores on social support and health satisfaction scales were higher than their individual averages.

METHODS/MATERIALS

Data were used from a subsample of older adults living at home who participated in a longitudinal study initiated by researchers from the University of Tours. They were collected at five time points over a 9-year period (T1: 2003; T2: 2005; T3: 2007; T4: 2009; T5: 2011). This study included 707 participants, and multilevel growth curve analysis was used on measures of depressive symptoms, gender differences, social support and health satisfaction.

RESULTS

Results indicated (1) a significant positive linear effect of age on depressive symptoms; (2) that women reported significantly higher scores of depressive symptoms than men at 63 years old (i.e., intercept) and that this gender difference remained constant across age; (3) that the slope of depressive symptoms appeared to increase at time points during which participants had higher levels of social support and to decrease when they had greater health satisfaction.

CONCLUSION

This study provides pertinent information about the change of depressive symptoms in older people living at home and particularly highlights the interest in studying gender, social support and health satisfaction.

The impact of street clothes among caregivers on residents with dementia in special care units: The STRECLO study

AIMS AND OBJECTIVES

To examine the impact of caregivers' street clothes on people living in special care units (SCUs). We hypothesised that caregivers wearing street clothes would improve residents' relationships with other residents and caregivers and, as a consequence, would improve their quality of life.

BACKGROUND

Environmental factors have been recognised as important elements in the care of people with dementia. Among these factors, the importance of the caregivers' appearance and more particularly their street clothes has been raised.

DESIGN

The Street Clothes study (STRECLO) was designed as a multicentre crossover observational study.

METHOD

This study was conducted in two volunteer nursing homes. It involved videotaping residents (N = 24) over a 6-month period: caregivers wore uniform and then street clothes for two consecutive three-month periods. Three outcome measures were observed as follows: (a) behaviours of residents, (b) contents of conversations and (c) proximal interactions between residents and caregivers. The STROBE checklist was used to ensure quality reporting during this observational study.

RESULTS

When caregivers wore street clothes, we observed the following: (a) greater solicitation and less anxiety in residents, (b) content of conversations between residents and caregivers included more personal and less health information, and (c) more proximal interaction between caregivers and residents.

CONCLUSION

To our knowledge, this is the first study which investigated the long-term effects on residents of SCU caregivers wearing street clothes. Our study demonstrated the potential benefit of not wearing uniform on the quality of life of institutionalised people with dementia.

RELEVANCE TO CLINICAL PRACTICE

Given the budgetary constraints faced by nursing homes, wearing street clothes for caregivers could be readily applied to clinical practice and represents a promising way to increase the quality of life of dementia residents and their families.

The Assessment of Eating Pleasure among Older Adults: Development and Preliminary Validation of the Anticipatory and Consummatory Eating Pleasure (ACEPS)

OBJECTIVE

Maintaining eating pleasure as long as possible is one of the determinants that contributes to and encourages good nutrition in the ageing population. Our study aimed to translate, adapt to the context of food and validate the Temporal Experience of Pleasure Scale (which distinguishes anticipatory and consummatory experiences of pleasure) in a food dependent older French population.

DESIGN

Prospective validation study.

SETTING

199 participants dependent for their meals, over 65 years old and living at home.

MEASUREMENTS

A pool of 16 self-reported items constituted the initial version of the anticipatory and consummatory eating pleasure scale (ACEPS). Demographic data, nutritional status, appetite and depressive mood were also assessed.

RESULTS

The exploratory factorial analysis and also the confirmatory factor analysis highlighted a two-factor model: anticipatory eating pleasure (four items) and consummatory eating pleasure (four items). The ACEPS showed good internal consistency. A higher score on the ACEPS positively correlated with appetite. Consummatory eating pleasure positively correlated with nutritional status and negatively correlated with depressive moods. The oldest-old and also those receiving a meals-on-wheels service had lower scores for anticipatory pleasure (r=-.14, p<.03).

CONCLUSION

To our knowledge, the ACEPS is the first comprehensive measure of eating pleasure distinguishing anticipatory and consummatory pleasure. This short measure, easily applicable on older people with vulnerability, allows early identification and intervention preventing malnutrition and decline in health. Specifically, encouraging anticipatory eating pleasure may be a first step to improving food intake among older adults.

Intergenerational programs: What can school-age children and older people expect from them? A systematic review

Over the past 40 years, there has been a growing trend for intergenerational initiatives worldwide. Intergenerational programs (IGPs) aim to facilitate cooperation and exchange among different age groups. While most studies highlight the benefits for each generation, the programs and study designs vary widely. We conducted a systematic review of the scientific literature between 2005 and 2015 to: (1) characterize and define the IGPs studied and (2) identify the benefits for school-age children and older people aged 60 years or over. First, 53 articles with defined keywords were collected from online databases. Then, using inclusion and exclusion criteria, 11 articles were selected. These were classified according to methodological quality and were analyzed one by one. The content of the programs varied: three involved artistic activities, three educational activities, one health, three open-ended activities, and one was organized around a citizen's project. Concerning the benefits of IGPs for children and older adults, some studies highlighted significant differences in positive attitudes, behaviors, confidence, and competence for the children, and significant differences in mental and physical health, and quality of life for older adults. However, it should be noted that those benefits are not systematic. Our findings are discussed in the light of the meaningfulness of the activities and the role of IGPs, organization of the program, and participants' knowledge of the other generation. Future studies may wish to consider searching for additional variables to further refine our understanding of the benefits for participants.

The Geriatric Depression Scale: does it measure depressive mood, depressive affect, or both?

OBJECTIVE

Self-report measures of depression are highly important tools used in research and in various healthcare settings for the diagnosis of different levels of depression. The Geriatric Depression Scale (GDS) is the first and the most popular scale used to screen for late-life depression. It is endorsed by the Royal College of Physicians and the British Geriatric Society (1992). The purpose of the present research was to investigate whether scores on the GDS₁₅ capture depressive mood (i.e. trait depression), depressive affect (i.e. short-term depressive state), or both.

METHODS

For this purpose, a trait-state model (stable trait, autoregressive trait, and state model) was applied to GDS₁₅ scores obtained at four time points over a 6-year period among a sample of community-dwelling older persons (N = 753). This model allows decomposing the GDS₁₅ scores into three different variance components: stable trait variance, autoregressive trait variance, and state variance.

RESULTS

Our findings revealed a general pattern of a major proportion of stable trait (69%) and autoregressive trait (22%) variance and a very smaller amount of state variance (9%) in the GDS scores across 6 years. Age and gender (i.e. being female) were shown to be positively linked to more stable trait variance.

CONCLUSIONS

Depression, as assessed with the GDS₁₅ , should be regarded as a relatively stable and enduring trait construct, reflecting a stable core of a person's depressivity. The negligible amount of state elements in the variation of the GDS₁₅ scores provides evidence that changing the context will not be enough to cause significant changes in depressive symptoms.

Validation of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-Sp12) on French Old People

The study aimed to develop a French version of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being short version (FACIT-Sp12), in order to provide a self-reported measure for French people in the field of gerontology. The study involving 63 nursing home residents was conducted to evaluate the construct validity, reliability, and convergence validity of the FACIT-Sp12. A confirmatory factor analysis corroborated a three-factor model (Meaning, Peace and Faith) with modifications for two items, also valid among people with cognitive impairment. Subscales showed good internal consistency and are correlated with quality of life and depression. In conclusion, the validated French version is an suitable instrument to study the maintenance and promotion of quality of life in the elderly.

Tenacious goal pursuit and flexible goal adjustment in older people over 5 years: a latent profile transition analysis

BACKGROUND

previous research has shown that tendencies to tenaciously pursue goals (TGP) and flexibly adapt goals (FGA) relate to well-being of older people.

OBJECTIVES

this study aimed to identify subpopulations of elderly people with different coping profiles, describe change in participants' profiles over time and determine the influence of coping profiles on well-being over a 5-year period.

METHODS

latent profile transition analysis (LPTA) was used in a three-wave longitudinal data collection measuring flexibility, tenacity, depression, self-rated health and life satisfaction among an elderly population over 65 years old.

RESULTS

three coping profiles were identified. Profile 1 was characterised by participants with high flexibility and tenacity scores, Profile 2 with moderate flexibility and low tenacity scores and Profile 3 with low flexibility and moderate tenacity scores. Results indicate stability of these profiles over time, with Profile 1 being the most adaptive in terms of ageing well.

CONCLUSION

high flexibility and tenacity in older people is a stable coping profile that is associated with successful ageing.

Does flexible goal adjustment predict life satisfaction in older adults? A six-year longitudinal study

OBJECTIVE

The aim of the present study was to investigate the relationship between flexible goal adjustment and life satisfaction (as an enduring component of subjective well-being) using six-year longitudinal data from a sample of older adults.

METHODS

The study included 704 participants aged 63-97 years assessed four times over a six-year period. Simultaneous and lagged models were specified and estimated using structural equation modeling.

RESULTS

Both simultaneous and lagged coefficients indicated that a high score on flexible goal adjustment significantly predicted subsequent levels of life satisfaction.

CONCLUSION

In line with successful aging theory, our findings support the view that the ability to adjust personal goals flexibly is a central resource when unattainable goals are encountered and it contributes to well-being in old age.

Relationship between life satisfaction and physical health in older adults: a longitudinal test of cross-lagged and simultaneous effects

OBJECTIVE

The emergence of positive psychology propelled scientific interest in the causal relationships between subjective well-being (SWB; e.g., happiness, life satisfaction [LS], positive affect) and physical health. However, it is becoming a controversial topic. Indeed, dependent on approach, LS is either considered a cause (top-down) or an effect (bottom-up). The aim of the present study was to investigate both cross-lagged and simultaneous effects between LS (as an enduring component of SWB) and physical health (as measured by self-perceived health and self-reported diseases), using 8-year longitudinal data from a sample of older adults.

METHOD

The study included 899 participants aged 64 to 97 years and assessed 5 times over an 8-year period. Cross-lagged and simultaneous models were specified and estimated using structural equation modeling.

RESULTS

Both cross-lagged and simultaneous coefficients indicated that poor health significantly predicted subsequent levels of life dissatisfaction, but LS did not predict subsequent levels of health.

CONCLUSIONS

These findings contradict, at least in our older sample, the postulates of positive psychology, and support the bottom-up approach to well-being as well as the popular adage, "As long as you've got your health."

Coping with negative life events in old age: the role of tenacious goal pursuit and flexible goal adjustment

OBJECTIVE

This study examines the relationships between negative life events and tenacious goal pursuit (TGP) and flexible goal adjustment (FGA), two fundamental modes of self-regulation suggested by Brandtstädter, and their effects on mental health.

METHODS

TGP/FGA, negative life events and depression were assessed in 670 elderly people living in the community. Hierarchical regressions were carried out to examine the effects of the two self-regulation modes and negative life events on depression.

RESULTS

Findings demonstrate the role of TGP and FGA in coping with negative life events. While both FGA and TGP were related to depression, FGA was found to have beneficial effects for the participants who had encountered negative life events. With age, people become less tenacious, but no conclusive relationship was found between flexibility and age.

DISCUSSION

Our findings support the importance of both modes of coping for the mental health of older adults. In particular, the ability to adjust goals was shown to be critical as a way of preventing the development of depressive symptoms following negative life events.

Synthesis, Characterization, and Self-Assembly of Poly(N-vinylpyrrolidone)-block-poly(vinyl acetate)

Poly(N-vinylpyrrolidone)-block-poly(vinyl acetate) (PVP-b-PVAc) block copolymers of varying molar mass and hydrophobic block lengths were synthesized by xanthate-mediated radical polymerization. In order to control the molar mass of the hydrophilic PVP block, a xanthate chain transfer agent, S-(2-cyano-2-propyl) O-ethyl xanthate, was used. The PVP-b-PVAc block copolymer is composed of a hydrophilic and hydrophobic segment, and has the ability to self-assemble in aqueous solution. The PVP-b-PVAc block copolymers were characterized by 1H NMR spectroscopy to confirm their self-assembly in water. The critical micelle concentration was determined by fluorescence spectroscopy. A combination of dynamic light scattering, transmission electron microscopy, and static light scattering was used to further characterize the self-assembly of the block copolymers in water.

[Confocal microscopy in corneal dystrophies: a comparison between confocal slit scanning (ConfoScan P2) and laser scanning microscopy (Rostock Cornea Modul-HRT II)]

BACKGROUND

The object of this work was a comparison of confocal images of corneal dystrophies made by a slit scanning microscope versus a laser scanning microscope.

MATERIAL AND METHODS

Using the Rostock Cornea Modul-HRT II as a confocal laser scanning microscope the images of five patients with some epithelial, stromal and endothelial corneal dystrophies were acquired. The pictures were compared qualitatively with those taken by the slit scanning microscope "ConfoScan P2" from corresponding pathologies. Also, the images of normal corneas of ten healthy persons were acquired for a qualitative comparison.

RESULTS

Confocal images from both devices were able to provide significant helpful diagnostic findings about the corneal microstructure. Essential qualitative differences between the images of both devices used were not observed. Due to the additional hardware components and the software module for image acquisition, analysis and archiving, the RCM-HRT II is favoured over the "ConfoScan P2". Nevertheless, the evaluation in favour of the RCM-HRT II has to be confined because an optimised, user-friendly enhancement, the "ConfoScan 4" is currently available.

CONCLUSION

Evaluating corneal dystrophies in vivo, an equivalent utility of both technical approaches has been observed.

Positive illusions and mental and physical health in later life

There are three competing conceptions concerning the relationship between positive illusions and mental health: the 'traditional' mental health model, according to which an accurate perception of the self and the world is a cornerstone of psychological well-adjustment; Taylor and Brown's Social Psychological Model on mental health, which assumes that positive illusions promote good mental health; and Baumeister's Optimal Margin Theory, which states that too much accuracy is harmful to mental health, as are exaggerated illusions. These three models were evaluated in the elderly (n = 857 retirees ages 60-95) using the youthful bias, which is the illusion of being younger than one's real age. As a whole, the Social Psychological Model obtained the strongest support. Retirees who harboured an exaggerated youthful bias (more than 15 years) reported more satisfaction with leisure time, higher self-esteem, better perceived health, and less boredom proneness than those who felt as old as they were or who, except for perceived health, entertained a moderate youthful bias (between 1 and 15 years).

Caelorinchus abditilux Merrett, 1980, a junior synonym of Caelorinchus caudani (Koehler, 1896) (Teleostei: Macrouridae)

Comparisons between the holotype of Macrurus caudani Koehler, 1896 and the type series of Caelorinchus abditilux Merrett, 1980, show that the latter is a junior synonym of the former. Caelorinchus caudani (Koehler, 1896) is the correct scientific name for this valid species.
