SynopsisData from four studies were used to assess the psychometric properties of the 26 IQCODE items. The items were assessed in terms of item–total correlations, test–retest reliabilities, correlations with indicators of current cognitive functioning and correlations with indicators of pre-morbid cognitive functioning. These data were used to develop a 16-item short form. The short form was cross-validated in a new sample using dementia/delirium diagnosis as the validity standard. It was found to perform as well as the long form.

Neuropsychological Screening

AbstractObjective:With increasing numbers of children growing up with conditions that are associated with acquired brain injury, efficient neuropsychological screening for cognitive deficits is pivotal. Brief self-report measures concerning daily complaints can play an important role in such screening. We translated and adapted the pediatric perceived cognitive functioning (PedsPCF) self- and parent-report item bank to Dutch. This study presents (1) psychometric properties, (2) a new short form, and (3) normative data for the short form.Methods:A general population sample of children and parents was recruited. Dimensionality of the PedsPCF was assessed using confirmatory factor analyses and exploratory bifactor analyses. Item response theory (IRT) modeling was used to evaluate model fit of the PedsPCF, to identify differential item functioning (DIF), and to select items for the short form. To select short-form items, we also considered the neuropsychological content of items.Results:In 1441 families, a parent and/or child participated (response rate 66% at family level). Assessed psychometric properties were satisfactory and the predominantly unidimensional factor structure of the PedsPCF allowed for IRT modeling using the graded response model. One item showed meaningful DIF. For the short form, 10 items were selected.Conclusions:In this first study of the PedsPCF outside the United States, studied psychometric properties of the translated PedsPCF were satisfactory, and allowed for IRT modeling. Based on the IRT analyses and the content of items, we proposed a new 10-item short form. Further research should determine the relation of PedsPCF outcomes with neurocognitive measures and its ability to facilitate neuropsychological screening in clinical practice.

Abstract Background One of the challenges to ageing individuals and health care systems is the decline in cognitive function with increasing age. The present study investigates in which way loneliness and social isolation is associated with cognitive decline in an aged population in Europe. Furthermore, it investigates how these relationships vary across different cultural and social settings. Methods The study employs panel data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Data from respondents aged 50+ from 16 European countries were collected from 2011-2017 at up to four points in time. Loneliness was operationalized as the perception of feeling lonely, while social isolation was operationalized by a summary index of social network size and social interaction. The cognitive function measures included tests of verbal fluency, as well as immediate and delayed recall. A linear panel fixed-effects modelling approach was used, while controlling for potential time-variant confounders from the areas of demographics, mental and physical health and survey methodological characteristics. Results Preliminary results show that loneliness and social isolation are associated with cognitive decline, while the extent varied by the measure of cognitive functioning measured. Loneliness, social isolation and cognition descriptively all show substantial cross-national variation. Conclusions The study illustrates the impact of loneliness and social isolation on cognitive functioning across a number of European countries. Cognitive functioning is an important determinant to successful ageing, preventing its decline promotes self-sufficient, independent living in the elderly and good quality end-of-life. This can support the development of implementable and accessible prevention for at risk individuals. Key messages Investigating the impact of social isolation and loneliness on the cognitive functioning can help tailor easily accessible prevention measures of cognitive decline in the elderly. The study allows for the assessment of cross-cultural differences and need for targeted measures across a number of European countries.

Beneficial Effects

Aging is an inevitable and progressive biological process that leads to irreversible physiological and functional changes, also in the nervous system. Cognitive decline occurring with age can significantly affect the quality of life of older people. Docosahexaenoic acid (DHA) is necessary for the proper functioning of the nervous system; it can affect its action directly through its impact on neurogenesis and neuroplasticity, but also indirectly by affecting the functioning of the cardiovascular system or anti-inflammatory effect. Literature analysis shows that good nutritional status of n-3 fatty acids, determined on the basis of their level in blood plasma or erythrocytes, is associated with a lower risk of cognitive decline in selected cognitive domains, as well as a lower risk of dementia or Alzheimer’s disease, although studies are also available where the above relationship has not been confirmed. Apart from this, studies on DHA and EPA diet intake, as well as in the form of dietary supplements, show their beneficial effects in the context of cognitive functioning and the risk of dementia. Also, the results of intervention studies, although not explicit, suggest that high doses of DHA and EPA in the form of dietary supplements may slow down the process of deteriorating the cognitive functioning of the elderly within selected domains. Based on the review of the literature, it can be concluded that DHA and EPA play an essential role in the prevention of cognitive impairment.

Abstract Background The aim of this research was to analyze the psychometric properties of the Persian version of the Geriatric Anxiety Inventory (GAI-PV) and its short form (GAI-PV-SF) in a sample of older adults in Iran.Methods In this cross-sectional study, a sample of 150 community-dwelling and a psychogeriatric sample of 48 adults older than 60 years completed the GAI-PV and GAI-PV-SF, the anxiety sub-scale of the General Health Questionnaire (GHQ-28), the Geriatric Depression Scale (GDS-15), and the Structured Clinical Interview for DSM-IV (SCID-I).Results Both the GAI-PV and GAI-PV-SF exhibited excellent internal consistency and desirable concurrent validity against GHQ-28 and GDS-15. The optimal cutpoint score to detect current generalized anxiety disorder (GAD) was 10/11 and 13/14 for GAI-PV in the community-dwelling and psychogeriatric samples, respectively, and 3/4 for GAI-PV-SF in both study samples. A good test-retest reliability and a single-factor structure were also demonstrated.Conclusion Sound psychometric properties of the GAI-PV in both subsamples suggest that the instrument could be used successfully as an accurate screening instrument in the elderly Iranian population.

Summary.–-The short form of the Depression Inventory was administered to a variety of patient samples totalling 431 Ss. The correlation between test scores and clinicians’ ratings ranged from .55 for a hospitalized depressed sample to .67 for Ss in a general medical outpatient practice. The correlation between test scores on the two forms ranged from .89 to .97. When speed of administration is an important factor, the short form can serve as a satisfactory substitute for the long form of the inventory and is especially suited for screening medical outpatients for the presence of depression.

The Self-Compassion Scale (SCS) is a widely used instrument for measuring selfcompassion. In this study we examined psychometric properties of the SCS long and short form in a Slovenian community sample (N = 442). The total score reliability was satisfactory both in the long form (? = .91) and short form (? = .81). The reliability of subscales in the long form was between .66 and .84, and relatively low in the short form (from .45 to .72). We performed a confirmatory factor analysis and examined a one factor, a two factor a six-factor correlated model, a higher order model, and a bi-factor model. The six-factor and bi-factor models showed the best fit for the SCS-LF, and the six-factor model was the only acceptable fit for the SCS-SF. The correlation between the long and the short form is very high (r = .96). The SCS correlates in a predictable way with satisfaction with life, well-being, and attachment styles. We concluded that Slovenian versions of both the long and the short form of the SCS have generally from acceptable to good psychometric properties. Results supported the use of both the total score and subscale scores of SCS-LF. The short version of the SCS can be used as a good and economical alternative when the aim is to use the total score.

This study examined the psychometric properties of the Sex-Role Ideology Scale in Portugal. In the first of 2 samples were 139 undergraduate volunteers. Internal consistency was .75, and a factor analysis gave some support for a unidimensional solution, which is consistent with scoring provided by the authors of the scale. Given the continuing ambiguity about the factor structure of the scale, we developed a unidimensional short form of 14 items. There was a tendency for the women to obtain higher scores for Egalitarianism than the men. 93 women of the second sample provided data for cross-validation of the structure of the short form.
