Psychological Dimensions

Objective: Affective lability is an important dimension of adult ADHD, associated with marked impairments and worse outcomes. A valid and quick tool to measure affective lability may therefore be of interest. Method: In 187 adult ADHD patients, we explored psychometric properties of the Affective Lability Scale–Short Form (ALS-18 items). We analyzed the construct validity and the external validity of the scale. Patients were compared with 48 healthy adult controls. Results: The three-factor structure of the ALS-18 presented a good fit and a good internal consistency. The correlations between the ALS-18 and ADHD symptoms and other psychological dimensions were, respectively, low and moderate. ALS-18 scores were higher in patients than in healthy adults. Conclusion: ALS-18 showed good psychometric properties in ADHD adult patients, allowing us to recommend the implementation of ALS-18 in assessing affective lability for clinical and research purposes. Use of ALS-18 should improve the clinical assessment of affective lability in adult ADHD patients.

Internal And External Validity

Abstract: Recently, Duriez, Fontaine and Hutsebaut (2000) and Fontaine, Duriez, Luyten and Hutsebaut (2003) constructed the Post-Critical Belief Scale in order to measure the two religiosity dimensions along which Wulff (1991 , 1997 ) summarized the various possible approaches to religion: Exclusion vs. Inclusion of Transcendence and Literal vs. Symbolic. In the present article, the German version of this scale is presented. Results obtained in a heterogeneous German sample (N = 216) suggest that the internal structure of the German version fits the internal structure of the original Dutch version. Moreover, the observed relation between the Literal vs. Symbolic dimension and racism, which was in line with previous studies ( Duriez, in press ), supports the external validity of the German version.

Summary: Self-concept is a construct consisting of a group of specific self-perceptions that are hierarchically organized. Age-associated changes of self-concept are related to the individual's perception of the changes occurring throughout the aging process. The authors examined external validity and internal consistency of an instrument that has been developed to assess self-concept in older adults and examined self-concept's characteristics in two different contexts. Results confirm the multidimensionality of the scale and show a satisfactory external validity, indicating good discriminatory capacity. Findings support the hypothesis that older people who live in a nursing home have a poor self-esteem, self-concept, and psychological well-being and have a greater presence of depressive symptoms than people who live in their own home.
