Background: The Work Ability Index (WAI) is an instrument that measures work ability. The wide dispersion of the WAI internationally has led to its adaptation for use in different countries. This study aimed to evaluate the psychometric properties of the Spanish version of the WAI. Methods: A methodological design was used over an opportunistic sample of 233 workers in the aeronautical industry in Spain. Reliability was evaluated through internal consistency. Factorial validity, known groups, and convergent validity were tested. Results: The Cronbach's alpha and item-total correlation indicated an adequate internal consistency. The confirmatory factor analysis, performed to evaluate the factorial validity, found adequate fit indices for a two-factor solution with a high correlation between the factors. Factor 1, "Subjectively estimated work ability and resources", was composed of 3 subscales and factor 2, "Ill-health-related", of 2 subscales. Subscales 4 and 6 had loading in both factors. Workers under 45 years of age obtained higher significant scores than older ones. Convergent validity was also evidenced since WAI was highly correlated with self-assessment of health status. Conclusions: The Spanish version of the WAI has shown evidence of reliability and validity in this study, supporting its use in individual and collective health surveillance by occupational health professionals. The factorial solution that was found has previously been reported in another international context. However, further research is needed to resolve the discrepancies detected in the role of some subscales between other national and international studies.

This study investigated whether the schema modes have validity in Korean adults. We examined the validity and reliability of the Schema Mode Inventory (SMI) in a Korean adult sample (N = 768; Mean age = 22.29 years; range = 19-55 years; 69.3% Males). Psychometric properties, such as factor structure, internal reliability, as well as intercorrelations among subscales were assessed. Confirmatory factor analyses yield satisfying fits for a 61-item Korean Schema Mode Inventory. Thirteen Schema Mode Inventory scales were found to have adequate reliability of the original 14 schema factors. Furthermore, the SMI scales differentiated between depressed and non-depressed participants as theoretically predicted. These findings imply that the SMI is a sound instrument to measure the schema mode model in a Korean setting for assessment prior to schema therapy.

This study examined replication of the factor structure of the DAPC [Domain-specific Assessment of Psychological Control (Soenens et al., 2006)] in parents of Korean adolescents. Participants included 289 adolescents who responded to DAPC items regarding their parents' psychological control behaviors. Two factors comprising 17 items were identified and labeled as "achievement oriented psychological control", and "separation-anxious psychological control." Confirmatory factor analysis and partial correlation analysis provided evidence for the construct validity of the DAPC through construct reliability, convergent validity and discriminant validity across both sex of parents and adolescents. The psychometric properties indicated that DAPC could be useful in studying parents' psychological control behaviors toward their adolescent children.

The importance of quality logistics service to the enterprises has kept growing considering the fierce competitions. It also asks for the sound definition and the scale explaining the construct of logistics service quality. The current study attempted to identify the construct of logistics service quality and develop the scale to measure it. Various qualitative and quantitative methodologies have been employed in order to provide the solid theoretical and psychometrical foundation of the proposed scale. In so doing, the conceptual definition of Logistics Service quality has been proposed and the 127-item scale measuring the construct of logistics service quality has been developed and found to be reliable and valid.

The psychometric properties of a preliminary version of the Friendship Quality Scale(FQS) were examined with data collected from 300 3rd and 5th grade children. Scores on the Self-Perception Scale were obtained to examine convergent validity. The FQS assesses friendship quality in 9 sub-scales, inclusive of 6 friendship functions. Factor analysis confirmed the 9 sudscale structure of the FQS for 5th graders, but 4 friendship functions instead of 6 were a better fit for 3rd graders. Except for one, the sub-scales showed relatively high internal consistency ; Cronbach ${\alpha}$ ranged from .70 to .93. Convergent validity was indicated by correlations between self-perception and sex differences in friendship functions. Friendship functions and satisfaction were related to self-perceptions in social acceptance, behavior, and global self-worth. Girls reported higher friendship functions and satisfaction in friendship than boys.

Purpose: The aim of this study was to design and evaluate a scale for measuring the attitudes toward condom use in sexual relationships. Method: A questionnaire was administered to 631 college students using a convenience sampling method. The psychometric properties (reliability and validity) were evaluated. Result: As a result of the item analysis, 16 items were selected and the internal consistency alpha coefficient was .88. Results indicated that the condom attitude scale is composed of three factors: Interruption of sexual pleasure; Protection; and Image. The three factors accounted for 59.54% of the variance in the total scale. Also, condom attitude was statistically significant (t=7.389, p=.000) between consistent condom users and inconsistent users. Conclusion: The results demonstrate that condom attitudes are multidimensional, and the reliability and validity of the scale was supported.

The purpose of this study was to develop a scale for evaluation of preschool children's peer competence and to examine its validity and reliability. The 15 items of the preliminary scale were completed by teachers, and peer rating scale for assessment of peer acceptance was administered to 365 children 5 to 6 years of age. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between teacher's ratings of peer competence and children's ratings of peer acceptance for concurrent validity, and Cronbach's u for reliability. The 15 items of the scathe were found be satisfactory in terms of item response distribution and item discrimination. Factor analysis revealed that a 3-factor solution was the best fit: sociability, prosocial behavior, leadership in peer relations. Correlations between teacher's ratings and children's ratings were as significant. Cronbach'so ranged from .88 to .93 for three subscales and .93 for the total scale. It was concluded that the psychometric properties of the peer competence scale in general were acceptable for use.

This study examined the relationships between parenting styles, academic achievement, and behavioral adjustment of adolescents in Korea. Using a sample of 181 parents and their children (13-15 years old), parents completed the Parental Authority Questionnaire and adolescents filled out the Youth Behavior Checklist (CBCL) and provided their school grades. Factor analysis was conducted on the PAQ to confirm the psychometric properties. Hierarchical regression analysis was computed to determine the relationship between maternal and paternal parenting styles, academic performance, and children's internalizing and externalizing behaviors. Regression analysis revealed that mother's authoritative parenting style was positively related with adolescents' grades in English. However, father's permissive was negatively related with adolescents' grades in English, Mathematics, and Science. Mother's permissive parenting styles showed negative effects of internalizing and externalizing behavior problems whereas father's permissive parenting styles showed positive effects of internalizing and externalizing behavior problems.

Obsessive-compulsive disorder (OCD) affects approximately 2-3% of the adult population. OCD is associated with impairments in social and occupational functioning. Although there are effective treatments for OCD, many individuals who suffer from OCD go undiagnosed and untreated. Thus, improvements in the assessment and diagnosis of OCD are needed. This paper provides a review of the instruments used to assess and diagnose patients with OCD. We reviewed clinician-administered inventories and self-report questionnaires. The characteristics, strengths, weaknesses, reliability and validity of each instrument are discussed. We also reviewed the psychometric properties of the Korean version of each instrument.
