Factor structure, reliability, and validity of the Beck Anxiety Inventory in adolescent psychiatric inpatients
The purpose of this study was to examine further the factor structure, reliability, and validity of the Beck Anxiety Inventory (BAI) in samples of adolescents, ages 14 to 18 years. The BAI is a 21-item self-report measure of anxiety severity. The BAI total score differentiated between the inpatient and high-school adolescents. In the psychiatric inpatient sample, girls obtained higher anxiety-severity scores than boys; no gender differences were obtained for the BAI total score in the high-school sample. Confirmatory factor analyses did not provide adequate fit for the two- factor oblique BAI models to the separate male and female psychiatric inpatient data. Principal axes with varimax and promax rotations initially identified a four-factor solution in the separate male and female inpatient participants. However, second-order analyses of the primary factors provided stronger support for a single-factor structure in each sample. Estimates of reliability for the BAI were adequate in samples of psychiatric inpatient and high-school adolescents. Evidence for convergent and discriminant validity of the BAI was investigated separately in the male and female inpatient samples. Overall, the BAI showed acceptable psychometric properties in these populations.

- "The first three instruments were used to determine convergent validity of the SURPS subscales: the Beck Hopelessness Scale (BHS) which comprises 20 items of truefalse response (Beck et al 1974) and has shown adequate internal consistency in Mexican population (α=0.78) (Córdova and Rosales 2011); the Beck Anxiety Inventory (BAI) composed of 21 items rated on a Likert scale (0–3 points) (Beck et al 1988; Osman et al 2002) with an internal consistency of 0.84 in Mexican students (Robles et al., 2001) and the "

ABSTRACT: To validate the Substance Use Risk Profile Scale (SURPS) in a sample of Mexican adolescents, this brief 23-item self-report questionnaire has been developed to screen four high-risk personality traits for substance misuse, to guide targeted approaches to prevention of addictions in adolescents. The scale has been previously validated in United Kingdom, Canada, Sri Lanka and China. A sample of 671 adolescents aged 11-17 completed a Spanish translation of the SURPS as well as other measures of personality and substance use. The Spanish translation of the SURPS has moderate internal consistency, and demonstrated a four-factor structure very similar to the original scale. The four subscales show good concurrent validity and three of the subscales were found to correlate with measures of substance use. The Spanish translation of the SURPS seems to be a valid and sensitive scale that can be used in a Mexican adolescent population.

- "Respondents have to rate how much they have been bothered by each symptom over the past week on a 4-point Likert-type scale, ranging from 0 (not at all) to 3 (severely). Past research has reported good psychometric properties for the original [30–35] and the Italian version of the BAI as well [36, 37]. "

ABSTRACT: Objectives and Methods.The aim of the study was to investigate the construct validity of the ARSQ. Methods. The ARSQ and selfreport
measures of depression, anxiety, and hopelessness were administered to 774 Italian adults, aged 18 to 64 years. Results.
Structural equation modeling indicated that the factor structure of the ARSQ can be represented by a bifactor model: a general
rejection sensitivity factor and two group factors, expectancy of rejection and rejection anxiety. Reliability of observed scores was
not satisfactory: only 44% of variance in observed total scores was due to the common factors.The analyses also indicated different
correlates for the general factor and the group factors. Limitations.We administered an Italian version of the ARSQ to a nonclinical
sample of adults, so that studies which use clinical populations or the original version of the ARSQ could obtain different results
from those presented here. Conclusion. Our results suggest that the construct validity of the ARSQ is disputable and that rejection
anxiety and expectancy could bias individuals to readily perceive and strongly react to cues of rejection in different ways.

All questionnaires demonstrated good psychometric properties in terms of internal consistency reliability [34-37], test-retest reliability [30,34-36,38], convergent validity , and concurrent validity .

Eating disorders are serious mental illnesses that have a significant effect on afflicted individuals’ quality of life. Evidence has shown that they can be improved with treatment. Internet-based interventions are useful in engaging individuals with eating disorders in self-management and treatment. This study aimed primarily to identify the change in quality of life of individuals with disordered eating after participating in an open trial of an Internet-based self-help programme, and compared their quality of life at assessment with that of healthy controls. Factors affecting their quality of life were examined. Secondary outcomes related to symptom improvement were also reported.
This study included 194 individuals with disordered eating and 50 healthy controls. The former group was recruited from eating disorder outpatient clinics and treatment units, as well as via information disseminated through various Internet websites, while the healthy controls were recruited from university student newspapers and university campuses. The Medical Outcomes Study Short Form Survey (SF-36v2) was used to assess participants’ quality of life. Other measures were used to assess their symptoms and motivational stages of change to recover from an eating disorder. The Wilcoxon signed ranks test and one-way repeated measures ANOVA were used to identify the change in quality of life of individuals with disordered eating from baseline to 1-, 3- and 6-month follow-ups. The Mann–Whitney U test was employed to compare the difference in quality of life between participants with disordered eating and the healthy controls. Spearman rank order correlations were performed to examine the factors associated with quality of life.
The participants with disordered eating had significantly poorer quality of life than the healthy controls in both physical and psychological domains. The factors associated with their poor quality of life included dieting behaviour, use of laxatives, severe eating disorder psychopathology, depression and anxiety. Over a six-month follow-up period, a significant number of participants engaged in self-help behaviours using the Internet-based programme. They experienced improvements in their quality of life, eating disorder psychopathology, depression severity, anxiety level and motivational stages of change.
Internet-based self-help programmes have the potential to enhance quality of life in individuals with disordered eating and could be useful adjuncts to professional treatment.
