El Cuestionario de Conducta de Alimentación de Adultos (AEBQ, por su sigla en inglés derivada de Adult Eating Behavior Questionnaire) es una de las herramientas psicométricas más usadas para evaluar la conducta de alimentación. El objetivo de este estudio fue adaptar y analizar factorialmente la versión en idioma español del AEBQ. El cuestionario adaptado al idioma español se aplicó en un estudio piloto de 50 voluntarias universitarias entre 20 y 30 años de edad. Se utilizó la técnica de análisis factorial para reducir la dimensionalidad de los datos y evaluar preliminarmente su estructura. Se usó la estadística alfa de Cronbach para explorar la consistencia interna del cuestionario adaptado. El análisis factorial reveló una estructura de 8 factores que explican el 82,8 % de la variación de los datos, lo que es concordante con el número de dimensiones de la conducta de alimentación publicada para el AEBQ original. La consistencia interna fue alta, con valores de la estadística α de Cronbach entre 0,77 y 0,91 para las 8 dimensiones consideradas. En conclusión, la versión adaptada al idioma español del AEBQ presenta una razonable concordancia en su estructura de datos con el cuestionario publicado originalmente en inglés, así como una adecuada consistencia interna. Se deben realizar futuros estudios de mayor tamaño muestral que incluyan participantes de diferentes grupos de edad, sexo y estado nutricional. The Adult Eating Behavior Questionnaire (AEBQ) is one the most used psychometric tool to evaluate eating behavior. The objective of this study was to adapt and analyze the factorial structure of the Spanish version of the AEBQ. The adapted questionnaire was submitted to a non-probabilistic sample of 50 female university students aged 20 - 30 years old. A factorial analysis was used to preliminary assess data structure, while Cronbach's alpha statistic was used to assess internal consistency. Factor analysis revealed an8-factor structure explaining 82,8% of data variation, which is concordant with data structure of the original AEBQ. The internal consistency was high, with Cronbach's α between 0.77 and 0.91 for all eating behavior dimensions. In conclusion, this Spanish version of the AEBQ shows adequate concordance with the factor structure of the originally published AEBQ, as well as high internal consistency. Future studies will evaluate the validity of the questionnaire in different subpopulation groups according to gender, age or nutritional status

High Internal Consistency Reliability

We examined the factor structure and internal consistency reliability of the Spanish version of the Vividness of Visual Imagery Questionnaire which was applied to a sample of 850 secondary school students. Factor structure investigated by principal components analysis, followed by varimax orthogonal rotation, indicated that a single factor explained 37% of the variance. The internal consistency of the questionnaire was good (Cronbach α = 88) We conclude that the Spanish version of the questionnaire, like the English version, has a single factor and high internal consistency reliability.

Background: There are presently no validated scales to adequately measure the stigma of suicide in the community. The Stigma of Suicide Scale (SOSS) is a new scale containing 58 descriptors of a “typical” person who completes suicide. Aims: To validate the SOSS as a tool for assessing stigma toward suicide, to examine the scale’s factor structure, and to assess correlates of stigmatizing attitudes. Method: In March 2010, 676 staff and students at the Australian National University completed the scale in an online survey. The construct validity of the SOSS was assessed by comparing its factors with factors extracted from the Suicide Opinion Questionnaire (SOQ). Results: Three factors were identified: stigma, isolation/depression, and glorification/normalization. Each factor had high internal consistency and strong concurrent validity with the Suicide Opinion Questionnaire. More than 25% of respondents agreed that people who suicided were “weak,” “reckless,” or “selfish.” Respondents who were female, who had a psychology degree, or who spoke only English at home were less stigmatizing. A 16-item version of the scale also demonstrated robust psychometric properties. Conclusions: The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community. Results suggest that psychoeducation may successfully reduce stigma.

The internal consistencies of three habit-specific locus of control scales measuring drinking, smoking, and eating behavior were evaluated using coefficient alpha. The three scales, along with Rotter's I-E scale, were administered to 202 undergraduate students. Estimates indicated the scales showed reasonably high internal consistency. Scores on the smoking and drinking scales had the lowest correlations with scores on Rotter's generalized measure. Mean drinking scale scores were lower than those for smoking and eating, suggesting that people judge drinking to be under more personal control. The implications of habit-specific expectancies, particularly with regard to habit disorders, are discussed.

In all group therapeutic processes, there are interacting and interdependent mechanisms and changing conditions: the therapeutic factors (Corsini & Rosenberg, 1955; Yalom, 1995). These factors are intrinsic to the therapeutic process and unrelated to the type of group (Rorhbaugh & Bartels, 1975). The present study examines the factor structure of the questionnaire Factors Aspecific and Specific in the Group Therapy (FAT.A.S.-G.; Marogna, 2009), designed to investigate specific and non-specific therapeutic factors. The questionnaire was administered to 167 patients involved in a short-term psychotherapy group. The factor analysis identified two main dimensions: interdependence and the group as Object-Self. The Cronbach Alpha coefficients range from .88 to .93, showing high internal consistency between items.

Negative Consequences

Background: The Marijuana Consequences Questionnaire [MACQ] assesses marijuana-related problems. This 8-factor (50-items) measure covers a broad array of multiple dimensions encompassing 50 negative consequences of gradient severity that are particularly relevant in the context of college. The present study aimed to validate the Spanish version of the 50-item Marijuana Consequences Questionnaire (S-MACQ) by analyzing the psychometric properties of internal, convergent, and concurrent validity and estimating internal consistency. We also examined the correlation between the brief (SB-MACQ) and the full S-MACQ and whether they similarly correlate with marijuana outcomes and marijuana-related variables. Method: College students from the two largest public universities of Cordoba city (Argentina) completed an online survey as part of a broader study focused on marijuana use and risky sexual behaviors. Only data from students that reported last-year marijuana use (n=470; 70.6% women; Mean age 22.67±3.52 years; 45.7% enrolled in psychology) were included in the study. We conducted independent samples t-tests to evaluate differences in the number of negative consequences (for the total scale and for each S-MACQ dimension) as a function of biological sex or frequency of use. Confirmatory factor analyses (CFA) was conducted to examine the factor structure of the S-MACQ. We conducted Pearson correlation analyses to examine the association between the number of marijuana-related consequences as measured by the S-MACQ and scores (a) in the CUDIT, a standardized measure of marijuana-related problems (i.e., convergent validity), (b) frequency and quantity of marijuana use (i.e., concurrent validity), (c) motives for marijuana use (i.e., concurrent validity). We examined the Pearson correlation between the SB-MACQ and the S-MACQ and then we estimated the difference between the Pearson correlation of the SB-MACQ and the S-MACQ with all the marijuana outcomes and marijuana-related variables. Results: Results from the CFA supported an 8-factor structure. The scores of the S-MACQ showed appropriate internal, concurrent and convergent validity, alongside with adequate internal consistency. The S-MACQ was largely correlated with the SB-MACQ and the correlations between these two versions and marijuana outcomes/marijuana-related variables did not significantly differ. Discussion: Findings supported the S-MACQ as a valid measure to assess marijuana-related problems in Spanish-speaking students. The instrument can be used to identify a broad diversity of marijuana problems in this population.

High Internal Consistency Reliability

This article reports an initial validation of an instrument that measures basic interviewing skills and compares its psychometric results with another instrument that has been used more frequently to measure similar skills. Four field supervisors rated 30 students’ videotaped interviews (N=120) using two instruments, the validation, and a comparison instrument. The current validation instrument had high internal consistency reliability, a clear factor structure, and performed well in construct validity evaluations. These preliminary results supported the instrument’s internal consistency reliability, content, factorial, and construct validity. The validation instrument had higher internal consistency reliability, lower errormeasurement, and amore interpretable factor structure than the comparison instrument.

The aim of this study was to analyze the cultural adaptation of the European Spanish version of the Perceived Stress Scale (PSS; Cohen, Kamarak, & Mermelstein, 1983), for its use in Mexican samples. Using a random sample of students, internal consistency was analyzed and the factor structure of the Spanish version of the PSS was compared with the factor structure found in the English version. Internal consistency was adequate (α = .83) and confirmatory factor analysis corroborated the factor structure. Factor 1 explained 42.8% of the variance and Factor 2 accounted for 53.2%. The goodness-of-fit measures also revealed an adequate fit. The cultural adaptation of the PSS was also evaluated with satisfactory results.

Abstract Background Suicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity. Methods Ninety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale. Results Principal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity. Conclusion The SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.
