Cross-cultural adaptation and psychometric properties of the Iowa-Netherlands Comparison Orientation Measure for the Brazilian context

Abstract Introduction The Iowa-Netherlands Comparison Orientation Measure (INCOM) was developed to measure individual differences in social comparison orientation and has been widely used in research and various different settings. Objectives The aim of this study was to adapt the online version of the INCOM and to evaluate its psychometric parameters when applied to a Brazilian population of university students. Methods The procedures were divided into two steps: step 1 - cross-cultural adaptation and analysis of content validity, and step 2 - assessment of psychometric characteristics. Step 1 comprised the processes of translation, evaluation by an expert committee, evaluation by the target population, and back-translation. For step 2, 1,065 university students were recruited and then factor analysis, analysis of reliability, and analysis of validity based on external measures were performed. Results The adaptation process yielded satisfactory results, including good indicators of content validity. Exploratory factor analysis revealed a two-dimensional structure and adequate factor loadings, except for item 11, which was excluded from the final version. Additionally, the final version of the scale had adequate fit indices (χ2 = 148.45, degrees of freedom [df] = 26; p < 0.001; root mean square error of approximation [RMSEA] = 0.06; comparative fit index [CFI] = 0.99; and Tucker-Lewis index [TLI] = 0.98). Evidence of reliability (Cronbach's alpha = 0.83) was observed and there were positive correlations with negative affect (r = 0.36) and negative correlations with positive affect and self-esteem (r = -0.15; r = -0.41, respectively). Conclusion The Brazilian version of the INCOM presents satisfactory psychometric parameters and can thus be used to measure social comparison orientation.

Cross-cultural adaptation and psychometric properties of the Iowa-Netherlands Comparison Orientation Measure for the Brazilian context.

INTRODUCTION: The Iowa-Netherlands Comparison Orientation Measure (INCOM) was developed to measure individual differences in social comparison orientation and has been widely used in research and different contexts. The aim of this study was to adapt the online version of the INCOM and to evaluate its psychometric parameters when applied to a Brazilian population of university students. METHODS: The procedures were divided into two steps: step 1 - cross-cultural adaptation and content validity, and step 2 - assessment of psychometric characteristics. In step 1, the processes of translation, evaluation by expert committee, evaluation by the target population, and the back-translation, were performed. In step 2, 1065 university students participated and factor analysis, analysis of reliability and validity based on external measures were performed. RESULTS: The adaptation process showed satisfactory results, such as good indicators of content validity. Exploratory factor analysis indicated a two-dimensional structure and adequate factor loadings, except for item 11, which was excluded from the final version. Also, the final version of the scale presented adequate fit indices (χ2 = 148.45, df = 26; p < 0.001; RMSEA = 0.06; CFI = 0.99; TLI = 0.98). Evidence of reliability (Cronbach's alpha = 0.83) was found, in addition to positive correlations with negative affect (r =0.36) and negative correlations with positive affect and self-esteem (r = -0.15; r = -0.41, respectively). CONCLUSION: The Brazilian version of the INCOM presents satisfactory psychometric parameters and can thus be used to measure social comparison orientation.

Theoretical procedures of the cross-cultural adaptation process of the Child Mania Rating Scale - Parent Version (CMRS-P) for the Brazilian context.

OBJECTIVES: To describe the theoretical procedures employed in the process of cross-cultural adaptation (CCA) for Brazil of the Child Mania Rating Scale - Parent Version (CMRS-P). METHODS: Seven steps were carried out: (1) translations and synthesis; (2) Committee of Judges-I; (3) grammatical review; (4) Committee of Judges-II; (5) semantic analysis (pre-test); (6) back-translation; and (7) discussion with the authors of the original instrument. Participants were two professional translators, 14 experts, a grammar proofreader, and 21 parents/guardians, representatives of the target population. The results were analyzed in terms of the percentage of agreement between evaluators and the content validity coefficient (CVC) and by analysis of comments and suggestions. RESULTS: Grammatical and cultural adjustments were made, in addition to substitution and/or inclusion of words and examples. Adequacy agreement indexes exceeding 86% were achieved and the CVC result for the total scale was excellent (0.95). The pre-test indicated good acceptance and understanding by participants. CONCLUSION: The proposed version proved to be promising for use in the Brazilian context, although further psychometric studies are still needed to prove the scale's validity and reliability.

Evidence of validity of the revised Helping Alliance Questionnaire based on the internal structure in a Brazilian clinical sample.

The revised Helping Alliance Questionnaire (HAq-II) is among the most used instruments that measure therapeutic alliance. Despite its use in research, this instrument is not validated for the Brazilian population. The aim of this study was to explore the evidence of validity of the HAq-II based on the internal structure in a sample of Brazilian psychiatric patients. An ambulatory convenience sample of 204 patients with major depressive disorder (MDD) and 81 patients with obsessive-compulsive disorder (OCD) was randomized between two different types of treatment. The HAq-II was completed by patients (patient version) and by 33 therapists who performed the interventions (therapist version) between the second and third sessions. We used confirmatory factor analysis (CFA) to investigate two models: (1) a one-dimensional therapeutic alliance model and (2) a two-dimensional model considering the factors 'positive alliance' and 'negative alliance'. The internal consistency of the HAq-II was measured by Cronbach's alpha. To investigate discriminant validity, we used the t-test for independent samples, ANOVA and Pearson's correlation coefficient. The analysis showed that the best model of the instrument was one-dimensional. Cronbach's alpha for both versions displayed values above 0.89. The Brazilian version of the HAq-II presented properties similar to those found in the original version. However, studies related to the one-dimensional model with other samples are necessary.

Development and psychometric validation of Internet Gaming Disorder Scale-Short-Form (IGDS9-SF) in a Brazilian sample.

OBJECTIVES: The aim of this study was to develop and examine the psychometric properties of the IGDS9-SF in a sample of Brazilian gamers and to find the best cut-off point for this instrument using a normative and clinically diagnosed sample of gamers. METHODS: A total of 610 participants were recruited to the present study. Construct validity was assessed through Exploratory and Confirmatory Factor Analysis (EFA, CFA). Criterion-related validity was established through the associations with Game Addiction Scale (GAS) and weekly gameplay. Reliability analysis was performed using the Cronbach's alpha (α) as the indicator of internal consistency. A cut-off point was estimated using the Receiver Operating Characteristics Curve (ROC curve) where the results of a clinical assessment was used as the gold standard. RESULTS: EFA and CFA findings confirmed the single-factor structure of the IGDS9-SF. Positive correlations indicated adequate criterion-related validity, and the scale was shown to be reliable (α=0.82). Finally, the optimal cut-off point for risky gaming was found to be >16 points and for diagnosis to be >21 points. CONCLUSIONS: This study provides validity and reliability evidence for the use of the Brazilian version of the IGDS9-SF in the assessment of Internet Gaming Disorder, further supporting its usefulness as a robust psychometric tool that can be employed in clinical and research settings in Brazil.

[Childhood anxiety and assessment instruments: a systematic review]. / Ansiedade infantil e instrumentos de avaliação: uma revisão sistemática.

OBJECTIVE: To make a survey of the principal anxiety instruments available for children, when they appeared, the type of methods used, verifying which countries have the highest number of children anxiety instruments and also how is the Brazilian reality on this matter. METHODS: A systematic review on electronic databases--Psychoinfo (1940--May 2002), Psyclit (1887--May 2002), Medline (1966--May 2002) e Eric (1966--May 2002). Information collected on personal communications and books chapters. The inclusion criterion utilized: studies realized with children, where the anxiety were evaluated with some psychometric instrument. The exclusion criterion: adolescents, adults and animal research articles, articles utilizing projective instruments or studies without any reference of assessment instruments. The indexed articles found in 2 or more databases were considered only once. RESULTS: This review pointed out 1911 studies used at least one assessment instrument to identify the presence of anxiety and 118 instruments were used for this purpose. CONCLUSIONS: There are a large number of children anxiety instruments available, however, in Brazil, the only one available in the market isn't updated and the modern ones are found only in clinic academic centers.
