IntroductionH&F Multidimensional Perfectionism Scale is a widely used measure of perfectionism developed to measure Self-oriented perfectionism (SOP), Socially-prescribed perfectionism (SPP) and Other-oriented perfectionism (OOP) dimensions. The original scale comprises 45-likert items. We have previously developed a short version of The H&F-MPS, with 13 items, showing adequate validity in a sample of university students, using principal component analyses method with factors varimax rotation.ObjectiveTo examine the factor structure of the H&F-MPS13 with confirmatory factor analysis (CFA), using a different sample of Portuguese university students.MethodsThe sample comprises 245 university students (68.9% females), with a mean age of 20.95 years (SD= 2.19; range= 17–33) who completed the H&F-MPS13. CFA was used to test the model suggested by prior exploratory factor analyses of H&F-MPS13.ResultsAfter correlated errors, we obtained a good fit for the second-order factor (X2/d= 2.577; CFI= 0.928; GFI= 0.915, RMSEA= 0.080; P[rmsea ≤ 0.05] = 0.001). The H&F-MPS13 showed acceptable internal consistency (α= 0.77) and the three dimensions presented Cronbach's alphas ranging between acceptable and good (α OOP = 0.67; SPP = 0.73; SOP = 0.89).ConclusionsThe H&F-MPS13 obtained through CFA is a reliable and valid measure to assess perfectionism in Portuguese university students.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionThe Eating Attitudes Test-40 (EAT-40) is a valid index of symptoms frequently observed in eating disorders. The EAT-40 was adapted and validated for the Portuguese population. Thereafter a short-version composed of 25 items selected from the exploratory factor analysis (EAT-25) was developed. Apart from the total score, the TAA-25 evaluates three dimensions: Diet, Bulimic Behaviours and Social Pressure to Eat.ObjectiveTo examine the factor structure of the EAT-25 using confirmatory factor analysis (CFA) in a sample of Portuguese women.MethodsThe sample was composed of 433 women (mean age = 36.07; SD = 15.15). CFA was used to test the model suggested by prior exploratory factor analyses of EAT-25. AMOS software was used.ResultsAfter four items were deleted and some errors were correlated, CFA indicated a good fit for the second-order factor (χ2/df = 3.066; CFI = 0.918; GFI = 0.883, RMSEA = 0.069; P[rmsea ≤ 0.05] < 0.001). The 19-item TAA showed excellent internal consistency (α = 0.91) and the three dimensions presented good Cronbach's alphas (α > 0.80).ConclusionsThese findings suggest that the 21-item TAA model obtained through CFA is a reliable and valid measure to assess disordered eating attitudes among women.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionThe F-Multidimensional Perfectionism Scale is a widely used instrument to assess perfectionism trait. The original scale comprises 35-items that measure the six dimensions of Frost et al (1990) conceptualization of perfectionism: personal standards (PS), concern over mistakes (CM), doubts about actions (DA), parental criticism (PC), Parental expectations (PE) and Organization (O).ObjectiveTo examine the factor structure of the 24-items short form of the F-MPS using confirmatory factor analysis (CFA), in a sample of Portuguese university students.MethodsThe sample comprises 344 university students (68.4% females), with an average age of 20.69 years (SD = 1.59; range = 17–24). They completed a version of F-MPS with 24 items that results from the selection of the four items with highest loadings in the respective six dimensions of the original Portuguese version (Amaral et al., 2013).ResultsAfter correlated errors, we obtained a good fit for the FMPS with six factors (X2/df = 2.125; CFI = .936; GFI = .891, RMSEA = .057; P[rmsea≤ .05] = .043). The 24-item F-MPS short form revealed good internal consistency (α = .825). The six dimensions showed acceptable or good internal consistency, as revealed by Cronbach's alpha (α: PS = .80; CM = .76; DA = .82; PC = .84; PE = .89, O = .85).ConclusionsThe F-MPS 24 items short form CFA confirmed the six factor model as a reliable and valid measure to assess multidimensional perfectionism in Portuguese university students.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Weight Stigmatization

The present study was intended to develop a scale to measure perceived weight stigmatization among people with obesity. The study was conducted in five steps. In first step, three focus group discussions were conducted with female obese university students to get the first-hand information related to weight stigmatization. Step two involved four interviews which were conducted with male obese university students to collect detailed information about weight stigmatization experiences of men. Step three included content analysis of qualitative data for item generation. In step four, judge’s opinion was taken, and a committee approach was carried out to select the items for the initial form of the scale. Items for final form of the scale were selected through exploratory factor analysis and confirmatory factor analysis in step five. For exploratory factor analysis, 150 university students (men = 61, women = 89) were included in the sample, whereas, for confirmatory factor analysis, another group of students (men = 78, women = 72) participated in the study. Principal Component Factor Analysis revealed three meaningful structures including Self-Perception, Perceived Social Rejection, and Perceived Impact containing 43 items. Confirmatory factor analysis confirmed this factor structure and all 43 items possessed factor loadings greater than .40. Moreover, results indicated that perceived weight stigmatization had high internal consistency (Cronbach’s alpha = .96) with three subscales having internal consistency .95, .83, and .92 respectively. Therefore, Perceived Weight Stigmatization Scale turned out to be a reliable and valid instrument for measuring perception of weight stigma in adults with obesity.

Abstract Background There is a dearth of instruments that have been developed and validated for use with children living with HIV under the age of 17 years in the Kenyan context. We examined the psychometric properties and measurement invariance of a short version of the Berger HIV stigma scale administered to perinatally HIV-infected adolescents in a rural setting on the Kenyan coast. Methods A cross-sectional study was conducted among 201 perinatally HIV-infected adolescents aged 12–17 years between November 2017 and October 2018. A short version of the Berger HIV stigma scale (HSS-40) containing twelve items (HSS-12) covering the four dimensions of stigma was evaluated. The psychometric assessment included exploratory factor analysis, confirmatory factor analysis (CFA), and multi-group CFA. Additionally, scale reliability was evaluated as internal consistency by calculating Cronbach’s alpha. Results Evaluation of the reliability and construct validity of the HSS-12 indicated insufficient reliability on three of the four subscales. Consequently, Exploratory Factor Analysis (EFA) was conducted to identify problematic items and determine ways to enhance the scale’s reliability. Based on the EFA results, two items were dropped. The Swahili version of this new 10-item HIV stigma scale (HSS-10) demonstrated excellent internal consistency with a Cronbach alpha of 0.86 (95% confidence interval (CI) 0.84–0.89). Confirmatory Factor Analysis indicated that a unidimensional model best fitted the data. The HSS-10 presented a good fit (overall Comparative Fit Index = 0.976, Tucker Lewis Index = 0.969, Root Mean Square Error of Approximation = 0.040, Standardised Root Mean Residual = 0.045). Additionally, multi-group CFA indicated measurement invariance across gender and age groups at the strict invariance level as ΔCFI was ≤ 0.01. Conclusion Our findings indicate that the HSS-10 has good psychometric properties and is appropriate for evaluating HIV stigma among perinatally HIV-infected adolescents on the Kenyan coast. Further, study results support the unidimensional model and measurement invariance across gender and age groups of the HSS-10 measure.

The A-ADS is one the first validated measures of attitudes of dementia in adolescents, though further validation is needed. 630 adolescents were recruited from secondary schools in England. A Principal Component Analysis was completed ( n = 230) followed by a Confirmatory Factor Analysis ( n = 400). Reducing the A-ADS into a single factor, 13-item measure (Brief A-ADS) improved the model fit of the measure (χ2 = 182.75, DF = 65, CMIN/DF = 2.81, p < 0.001, CFI = 0.90, RMSEA = 0.07). The scale demonstrated good internal consistency, good predictive and concurrent validity. Building on the validation of the A-ADS, the Brief A-ADS is suitable to capture attitudes towards dementia amongst adolescents.

Perseverative Thinking

IntroductionPerseverative Negative Thinking (PNT) is a transdiagnostic cognitive process [1] characterized by repetitiveness, intrusiveness and difficulties to disengage (Ehring, 2011). The Perseverative Thinking Questionnaire (PTQ-15; [2]) is a self-reported instrument, developed to evaluate these characteristics. The Portuguese version assess two meaningful dimensions – Repetitive thoughts (RT); and Cognitive interference and unproductiveness (CIU) [3].AimTo confirm the bi-dimensional structure of the PTQ-15 using Confirmatory Factor Analysis, in two distinct samples.MethodA sample composed of 256 students (Mean age = 20.58 ± 1.870; 78.1% girls) and a sample composed of 480 adults from the community (parents of the students; mean age = 50.84 ± 5.310; 53.1% women) filled the PTQ-15. We used software AMOS.ResultsThe second-order model of PTQ-15 with two dimensions presented good fit, in both students (CMIN = 2.449; RMSEA = 0.075; CFI = 0.958, TLI = 0.949, PGFI = 0.776; P < 0.001) and their parents (CMIN = 3.46; RMSEA = 0.072, CFI = 0.955, TLI = 0.942, PGFI = 0.632; P < 0.001). Internal consistency of the total scale, measured though Cronbach's alpha was α = 0.95/0.94; both factors presented good/excellent reliability: repetitive thoughts (a = 0.93/0.92); cognitive interference and unproductiveness (a = 0.88/0.92).ConclusionTaken together, both CFAs provided additional evidence that PTQ-15 is an adequate measure for perseverative thinking.Disclosure of interestThe authors have not supplied their declaration of competing interest.
