Body Dysmorphic Symptoms Scale for patients seeking esthetic surgery: cross-cultural validation study

Abstract

CONTEXT AND OBJECTIVE: Rhinoplasty is one of the most sought-after esthetic operations among individuals with body dysmorphic disorder. The aim of this study was to cross-culturally adapt and validate the Body Dysmorphic Symptoms Scale. DESIGN AND SETTING: Cross-cultural validation study conducted in a plastic surgery outpatient clinic of a public university hospital. METHODS: Between February 2014 and March 2015, 80 consecutive patients of both sexes seeking rhinoplasty were selected. Thirty of them participated in the phase of cultural adaptation of the instrument. Reproducibility was tested on 20 patients and construct validity was assessed on 50 patients, with correlation against the Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder. RESULTS:The Brazilian version of the instrument showed Cronbach's alpha of 0.805 and excellent interrater reproducibility (intraclass correlation coefficient, ICC = 0.873; P < 0.001) and intra-rater reproducibility (ICC = 0.939; P < 0.001). Significant differences in total scores were found between patients with and without symptoms (P < 0.001). A strong correlation (r = 0.841; P < 0.001) was observed between the YaleBrown Obsessive Compulsive Scale for Body Dysmorphic Disorder and the Body Dysmorphic Symptoms Scale. The area under the receiver operating characteristic curve was 0.981, thus showing good accuracy for discriminating between presence and absence of symptoms of body dysmorphic disorder. Forty-six percent of the patients had body dysmorphic symptoms and 54% had moderate to severe appearancerelated obsessive-compulsive symptoms. CONCLUSIONS: The Brazilian version of the Body Dysmorphic Symptoms Scale is a reproducible instrument that presents face, content and construct validity.RESUMO CONTEXTO E OBJETIVO: Rinoplastia é uma das operações mais procuradas por indivíduos com o transtorno dismórfico corporal. O objetivo deste estudo foi adaptar culturalmente e validar a Body Dysmorphic Symptoms Scale. DESENHO E LOCAL: Estudo de validação cultural desenvolvido no ambulatório de cirurgia plástica de um hospital universitário público. MÉTODOS: Oitenta pacientes consecutivos de ambos os gêneros que desejavam submeter-se à rinoplastia foram selecionados entre fevereiro de 2014 e março de 2015. Trinta pacientes participaram da fase de adaptação cultural do instrumento. A reprodutibilidade foi testada em 20 pacientes e a validade de construto em 50 pacientes, correlacionando-se a escala com a Yale-Brown Obsessive Compulsive Scale para transtorno dismórfico corporal. RESULTADOS: A versão brasileira do instrumento mostrou alfa de Cronbach de 0,805 e excelente reprodutibilidade interobservador (coeficiente de correlação intraclasse, CCI = 0,873; P < 0,001) e intraobservador (CCI = 0,939; P < 0,001). Houve diferença significante entre os escores totais de pacientes com e sem sintomas (P < 0,001). Observou-se forte correlação (r = 0,841; P < 0,001) entre a Yale-Brown Obsessive Compulsive Scale para transtorno dismórfico corporal e a Body Dysmorphic Symptoms S...

Mental health in rhinoplasty applicants, before and after surgery

“…Maximum mean of disorders was related to depression, obsession, physical complaint, in-dividual sensitivity, psychosis, anxiety, paranoid imagery, Phobia and aggression respectively. These results are conformed to the results of Tidi et al [24]. These results were also adapted to the study of Bili et al [14].…”

Short Mood and Feelings Questionnaire for screening children and adolescents for plastic surgery: cross-cultural validation study

“…33 Studies have reported retesting as early as a few hours after baseline testing. [24][25][26][27][28] The longer the time that elapses is, the lower the measured reliability will be, and the more likely it will be that knowledge or attitudes have in fact changed. 40 The instrument was tested for test-retest reliability (reproducibility) in three interviews conducted by two independent interviewers.…”

“…The number of patients participating in the cultural adaptation, reliability and validity phases was similar to that used in previous studies evaluating the psychometric properties of social construct measurements in plastic surgery populations, [23][24][25][26][27][28][29] and was in accordance with the methodology internationally accepted and used for translation, cultural adaptation and validation of instruments. [30][31][32][33][34] According to Sapnas and Zeller, 34 the traditional protocol for determination of an adequate sample size based on power analysis is not appropriate for studies assessing the psychometric properties of social construct measurements; a total sample size of 50 subjects or more is adequate for representing the study population.…”

Spanish Translation, Cultural Adaptation, and Validation of the Standardized Cosmesis and Health Nasal Outcomes Survey Questionnaire

“…However, many similar translation studies achieved a validation process with similar or a more limited number of participants. 9–11 Our results showed significantly the reliability and validity of the Spanish SCHNOS in our group of patients; we believe that the associations would only be stronger with a larger sample size.…”
