Study of the psychometric qualities of the Brief Social Phobia Scale (BSPS) in Brazilian university students

Purpose: To perform a psychometric analysis of the Brazilian version of the Brief Social Phobia Scale (BSPS). Materials and methods: Hundred and seventy-eight university students of both genders aged on average 21.2 years and identified as Social Anxiety Disorder (SAD) cases and non-cases was studied, with the structured clinical interview for DSM-IV being used as a parameter. The different instruments were applied in an individual manner in the presence of a rater and of an observer. Results: The BSPS showed adequate internal consistency (0.48-0.88) and concurrent and divergent validity with the Beck Anxiety Inventory (BAI) (0.21-0.62), Social Phobia Inventory (0.24-0.82) and Self Statements During Public Speaking Scale (SSPS) (0.23-0.31). Discriminative validity revealed a sensitivity of 0.88-0.90 and a specificity of 0.81(0.83 for cut-off notes of 18/19. Factorial analysis demonstrated the presence of six factors that jointly explained 71.79% of data variance. Construct validity indicated some limits of the scale regarding the diagnosis of SAD. Inter-rater reliability was strong (0.86-1.00, p < 0.001). Conclusions: The BSPS is adequate for use with university students, although further studies in different cultures, samples and contexts are still necessary. (C) 2009 Elsevier Masson SAS.

Construction and Validation of the Brazilian Questionario de Respostas Socialmente Habilidosas Segundo Relato de Professores (QRSH-PR)

Behavioral problems in preschool children are one of the most frequent motives for seeking psychological care by parents and caregivers. Instruments are considered necessary, created from a Social Skills Training theoretical-practical perspective, which may systematically assist the identification of social skills and behavioral deficits. helping professionals in the prevention and/or reduction of behavioral problems. The purpose of this study was to test the psychometric validity and reliability of an instrument for evaluation of Socially Skilled Responses. from a teacher`s perspective (QRSH-PR). For this purpose, 260 preschool children were evaluated. differentiated in subgroups without and without behavioral difficulties, based on the Child Behavior Scale (Escala de Comportamento Infantil/ECI-Professor). Studies were conducted for construct. discrimination. concurrent and predictive validity. The Cronbach Alpha was calculated to evaluate internal consistency. The obtained results pointed to positive indicators in reference to construct, discrimination, and predictive validity, and even for good internal consistency. indicating that the items consistently measure the construct of social skills, and differentiated children with and without behavioral problems. The questionnaire is considered to be gauged for evaluation of socially skilled responses from preschool children. and applicable in educational and clinical environments.

Comparability between telephone and face-to-face Structured Clinical Interview for DSM-IV in assessing social anxiety disorder

PURPOSE. This article evaluates the comparability of the telephone and in-person Structured Clinical Interview for DSM-IV (SCID) interviews in assessing patients with social anxiety disorder (SAD) as an independent anxiety diagnosis. DESIGN AND METHODS. One hundred subjects were randomly selected and interviewed with the SCID, once by telephone and once in person (1-3 months later). FINDINGS. The prevalence of SAD assessed with the telephone interviews was 56%, whereas the in-person prevalence was 52%, with no statistically significant difference. The test-retest kappa for the 200 interviews was .84, indication of excellent agreement. PRACTICE IMPLICATIONS. These findings, along with the existing evidence of their validity, should encourage the use of SCID by telephone for SAD diagnostic interviews.

Lo-Fi matchmaking: A study of social pairing for backpackers

It is technically feasible for mobile social software such as pairing or ‘matchmaking’ systems to introduce people to others and assist information exchange. However, little is known about the social structure of many mobile communities or why they would want such pairing systems. While engaged in other work determining requirements for a mobile travel assistant we saw a potentially useful application for a pairing system to facilitate the exchange of travel information between backpackers. To explore this area, we designed two studies involving usage of a low-fidelity role prototype of a social pairing system for backpackers. Backpackers rated the utility of different pairing types, and provided feedback on the social implications of being paired based on travel histories. Practical usage of the social network pairing activity and the implications of broader societal usage are discussed.

Prenatal Lipopolysaccharide Reduces Social Behavior in Male Offspring

Objective: This study investigated the relationship between maternal sickness behavior during pregnancy and offspring development and behavior. Methods: Pregnant Wistar rats were administered with lipopolysaccharide (LPS, 100 mu g/kg, i.p.) on gestation day (GD) 9.5. Dams` sickness behavior was analyzed, and at birth, offspring number and weight were evaluated. Male offspring was evaluated through physical development, play behavior, adult social interaction, plus maze studies and morphological analysis of the brain. Results: Results, with respect to the control group, showed that: (1) LPS decreased general activity, food intake, and weight gain in dams, but no pyrexia was observed following treatment; (2) LPS reduced litter size, but no alterations in physical development were observed; (3) LPS reduced play behavior parameters in baby rats; (4) LPS decreased adult social interaction; (5) no alterations were observed between groups on plus maze studies; (6) no differences were observed between groups on morphological analyses of the brain. Conclusion: These data reveal that LPS administered on GD 9.5 impaired male offspring`s social behavior in infancy and adulthood. These results may be related to an alteration in motivational states or/and increased anxiety. Copyright (C) 2010 S. Karger AG, Basel
