Exploring the Factor Structure of the Social Cognition and Object Relations–Global Rating Method: Support for Two- and Three-Factor Models

The Social Cognition and Object Relations Scales–Global Rating Method (SCORS–G) contains 8 scales for coding narrative content. This study explores the factor structure of this measure using college (n = 171), outpatient (n = 239), and inpatient (n = 78) samples. Participants told stories to the Thematic Apperception Test (TAT; Murray, 1943) cards. Stories were transcribed and coded by blind raters using the SCORS–G. Cases were randomly assigned to an exploratory or validation group. Exploratory factor analysis with the exploratory group suggested 2- and 3-factor models. The Emotional Investment in Relationships (EIR) scale did not obtain a primary loading on any factor and was not included in subsequentmodels. After modifications, confirmatory factor analysis indicated good-to-adequate fit for 2- and 3-factor models. Both models showed good fit in the validation group and met criteria for invariance across models. Findings indicated that some SCORS–G scales tap cognitive-structural elements, whereas others assess affective-relational components of narratives. We found mild support separating the affective-relational scales in terms of internal representations for the self and others and relationships. The results reported here indicate that clinicians and researchers can calculate a separate cognitive-structural composite score and an affective-relational composite score when using the SCORS–G to rate TAT stories.     

Applied Problem Solving in Children with ADHD: The Mediating Roles of Working Memory and Mathematical Calculation

The difficulties children with ADHD experience solving applied math problems are well documented; however, the independent and/or interactive contributions of cognitive processes underlying these difficulties are not fully understood and warrant scrutiny. The current study examines two primary cognitive processes integral to children’s ability to solve applied math problems: working memory (WM) and math calculation skills (i.e., the ability to utilize specific facts, skills, or processes related to basic math operations stored in long-term memory). Thirty-six boys with ADHD-combined presentation and 33 typically developing (TD) boys aged 8–12 years old were administered multiple counterbalanced tasks to assess upper (central executive [CE]) and lower level (phonological [PH STM] and visuospatial [VS STM] short-term memory) WM processes, and standardized measures of mathematical abilities. Bias-corrected, bootstrapped mediation analyses revealed that CE ability fully mediated between-group differences in applied problem solving whereas math calculation ability partially mediated the relation. Neither PH STM nor VS STM was a significant mediator. When modeled together via serial mediation analysis, CE in tandem with math calculation ability fully mediated the relation, explained 79% of the variance, and provided a more parsimonious explication of applied mathematical problem solving differences among children with ADHD. Results suggest that interventions designed to address applied math difficulties in children with ADHD will likely benefit from targeting basic knowledge of math facts and skills while simultaneously promoting the active interplay of these skills with CE processes.
