The social consequences of transformation in Slovakia

This article provides basic information about the transformation process in Slovakia from 1989 to 1994. Presented are some of the major results of the SOCO survey and selected important social topics are analyzed. Sociological information about income, property, consumption, and expenditures of Slovak households is given, and the economic activities of Slovak households and peoples’ attitudes to the transformation process are discussed. The article also addresses who are the winners and losers of the transition in the context of rising poverty and changes in social policy.     

Dopamine Genes and Pathological Gambling in Discordant Sib-Pairs

Pathological gambling (PG) is an impulse control disorder that has been considered as a behavioral addiction. Recent studies have suggested the involvement of the dopaminergic system in addictions and impulse control disorders and associations of dopamine receptor genes (DRD1, DRD2, and DRD4) and PG have been reported. In the present study, 140 sib-pairs discordant for the diagnosis of PG (70 males and 70 females on each group) were recruited through the Gambling Outpatient Unit at the Institute of Psychiatry, University of Sao Paulo and were assessed by trained psychiatrists. A family-based association design was chosen to prevent population stratification. All subjects were genotyped for dopamine receptor genes (DRD1 -800 T/C, DRD2 TaqIA RFLP, DRD3 Ser9Gly, DRD4 48bp exon III VNTR, DRD5 (CA) repeat) and the dopamine transporter gene (SCL6A3 40 bp VNTR). Our results suggest the association of PG with DRD1 -800 T/C allele T (P = .03).     

A Gender Lens on Quality of Life: The Role of Sense of Community,Perceived Social Support,Self-Reported Health and Income

Quality of life (QoL) refers to a subjective evaluation that is embedded in a cultural, social and environmental context. It is a multidimensional concept and its assessment covers four domains: physical health, psychological health, social relationships, and environment. Although many studies report on QoL, literature rarely addressed the question of the QoL predictors from a gender perspective. Present study aimed at investigating gender differences in the determinants of QoL. Specifically, gender was considered as a moderator in the relationship between predictors of QoL (i.e. socio-demographic characteristics, perceived health, income, social support and sense of community) and each dimension of QoL. 654 Italian adults participated in the study. Results show that men outscore women on the physical, the psychological and the environmental domains of QoL. Considering determinants of QoL, sense of community and self-reported health operate in a similar fashion for both genders. On the contrary, social support is more predictive for women’s QoL, whereas the income level is more significant for men’s QoL. Implications are discussed.     

Psychometric Properties of the Medical Outcome Study Social Support Survey with a General Population Sample of Undergraduate Students

Among non-clinical populations, perceived social support is an important factor in health maintenance and well-being. Among measures that purport to assess perceived social support, the Medical Outcomes Study Social Support Survey (MOS-SSS) is based on a strong conceptual framework and has been subjected to a rigorous psychometric evaluation. Since no studies have investigated its psychometric properties with a young, non-clinical population, the purpose of this study is to investigate the psychometric properties (construct validity, internal consistency, and test–retest reliability) of an Italian version of the MOS-SSS with a non-clinical population sample. A convenience sample of 485 undergraduate students (73.0 % female; mean age = 21.81 ± 1.52) has been recruited. With regards to scale dimensionality, the best fit measurement model found support for the four subscales proposed by the original version: emotional and informational support, tangible support, positive social interactions, and affectionate support (χ ²/df = 4.49; CFI = .92; TLI = .91; RMSEA = .08). MOS-SSS subscales showed good internal consistency (Cronbach’s alpha for the subscales ranged from .848 to .939). Significant correlations were found with measures of psychological well-being (Ryff’s Scales of Psychological Well-Being) and depression (Beck-Depression Inventory-II). Test–retest stability was tested by examining a subsample (N = 225) over a 10-week period (correlation coefficients for the subscales ranged from .502 to .579). The findings suggest that MOS-SSS presents good psychometric characteristics with a young general population sample. Therefore, the MOS-SSS seems to be a psychometrically sound measure for the evaluation of perceived social support among young non-clinical populations.     

Influence measure for the L1 regression

Because outliers and leverage observations unduly affect the least squares regression, the identification of influential observations is considered an important and integrai part of the analysis. However, very few techniques have been developed for the residual analysis and diagnostics for the minimum sum of absolute errors, L₁ regression. Although the L₁ regression is more resistant to the outliers than the least squares regression, it appears that outliers (leverage) in the predictor variables may affect it. In this paper, our objective is to develop an influence measure for the L₁ regression based on the likelihood displacement function. We illustrate the proposed influence measure with examples.     

Maximum likelihood estimation of a generalized star(p; 1p) model

Summary A STAR model is characterized by autoregressive terms lagged both in time and space. The model we call GSTAR presents also contemporaneous spatial correlation. Under the hypothesis of stationarity we derive conditional maximum likelihood estimators of the autoregressive parameters and a consistent estimator of their covariance matrix.     

Friendship in children with internalizing and externalizing problems: A preliminary investigation with the Pictorial Assessment of Interpersonal Relationships

This study examined the relationship between friendship representation and internalizing and externalizing problems in school-aged children. One hundred Caucasian 6–7 year-old children (50 males and 50 females) and their mothers took part in the study. The Draw-a-Man Test, the Pictorial Assessment of Interpersonal Relationships, and the Child Behavior Checklist (CBCL/6-18) were used. Children with internalizing problems, externalizing problems, comorbid internalizing and externalizing problems, and a control group were compared on their pictorial representations of friendship. Results showed that children with externalizing problems included more pictorial indices of each friend's autonomy and a larger imbalance of importance between them; children with internalizing problems drew themselves as less similar to their friends. In conclusion, children's pictorial representation allows exploring some aspects of their tacit knowledge about the relationship with a best friend, which is not easily expressed verbally by young children. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed.
