AbstractUsing Item Response Theory to analyse survey data from a representative sample of 551 Swedish citizens, a new 16-question measure of fact-based financial literacy is developed and validated. Uni-dimensionality of the measure is verified, and expected correlations are observed with an existing measure of fact-based financial literacy, a measure of subjective financial literacy or confidence, and age, gender, and income. A significant impact of fact-based and subjective financial literacy are found on three time-ordered stages of individuals’ retirement behaviour: planning, saving, and investment management. It is concluded that policies increasing final literacy are important in different phases of the life cycle.

Qualitative Analyses

DSM-5 ( Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) Section II criteria for borderline personality disorder (BPD) lack developmental operationalization. The aim of the current study was to evaluate whether DSM criteria operate similarly across adolescents and adults to determine if developmental adjustment for DSM criteria was needed. Three age cohorts were recruited: adolescents (ages 12-17 years; n = 484), young adults (ages 18-25 years; n = 442), and adults (ages ≥26 years; n = 953). The Child Interview for DSM-IV BPD and the Structured Clinical Interview for DSM-IV Axis II disorders were administered to adolescents and adults, respectively. Item response theory methods were used to evaluate differential item (or criterion) functioning (DIF) of BPD criteria across adolescents and adults. Qualitative analyses were then used to evaluate the potential sources of DIF. Item response theory results demonstrated DIF across adolescents and adults for all DSM BPD criteria. Qualitative analyses suggested that the source of DIF was most likely due to rater/interviewer bias. Results furthermore suggested that behavioral criteria may represent the heterotypic features of BPD, while intra- and interpersonal criteria represent the homotypic features of the disorder. The article concludes with recommendations for developmentally informed guidelines for the assessment of BPD.

Ability Estimate

The lack of valid and standardized instruments, directed on an assessment of the language domain in adolescents and adults in Russia postulates the urgent necessity of their development. To fi ll this gap, the language battery, ARFA-RUS, was created and applied in a large project investigating the long-term consequences of raring in institutional care settings on human development. In the current study, an Item Response Theory (IRT) approach was used to examine the psychometric properties of the Synonyms Subtest of ARFA-RUS as the fi rst step of validation of the battery. IRT results demonstrated the test is reliable for the low-to-moderate levels of the assessed ability; yet, to capture a wider ability range, more diffi cult items are needed. The ARFA-RUS Synonyms Subtest was less suitable for the postinstitutionalized group of adults; in this group, the latent ability estimate explained a lower percentage of variance in comparison to adults raised in biological families. With regard to item-specifi c analyses, two items demonstrated paradoxical patterns with decreased probability of correct response at increased ability. In addition, one item was eliminated from the fi nal version of the Synonyms Subtest due to its poor item fi t and low discrimination value.
