Impulsive States and Impulsive Traits: A Study of the Multilevel Structure and Validity of a Multifaceted Measure of Impulsive States.

ABSTRACT: Emerging evidence suggests impulsive states may be reliably measured in the moment using ecological momentary assessment (EMA); however, research has not investigated whether the multi-factor structure of impulsive traits also characterizes impulsive states. In two independent samples spanning adolescence through young adulthood (n = 211, n = 222), we adapted global self-report measures of impulsive traits to EMA and conducted multilevel confirmatory factor analyses to characterize the within- and between-person factor structure of five impulsive traits (negative urgency, planning, persistence, sensation seeking, and positive urgency). Across both studies, factor models with one factor for each UPPS-P facet fit the data well at both levels, though some latent factors were highly correlated. Aggregated impulsive states, especially negative urgency, predicted oppositional defiant disorder symptoms, emotional problems, alcohol problems, and attention deficit hyperactivity disorder symptoms. Our results suggest that EMA measures can capture a range of impulsive states that mirrors the heterogeneity seen in the trait literature.

Project description:Background Validity is the ability of an instrument to measure what it claims to measure. It means the degree to which the empirical evidence supports the trustworthiness of interpretations based on the calculated scores. The hematological malignancy (HM) specific patient reported outcome measure (HM-PRO), is a newly developed instrument for use in daily clinical practice as well as in research. This study, provides the evidence for construct validity of the HM-PRO, specifically focusing on the convergent and divergent validity compared to the other established instruments used in hematology. Methods This validation study adopted a prospective cross-sectional design where a heterogeneous group of patients diagnosed with different HMs and different disease state were recruited. A total of 905 patients were recruited from seven secondary care hospitals in the UK and online through five patient organizations. Patients were asked to complete the HM-PRO and other cancer specific PRO’s, FACT-G and EORTC QLQ C-30. Data analysis was performed using IBM SPSS 23 statistical software. Results A total of 486 males (53.7%) and 419 females (46.3%), with a mean age of 64.3 (± 12.4) years and mean time since diagnosis of 4.6 ( ± 5.2) were recruited. The total score of Part A of the HM-PRO highly correlated with the five functional scales of the EORTC QLQ-C30 (Physical = ?0.71, Role = ?0.72, Emotional = ?0.64, Cognitive = ?0.58, Social = ?0.74—p < 0.001). With respect to correlation with FACT-G, the total score of Part A of the HM-PRO highly correlated with Physical (?0.74), Emotional (?0.57), Functional (?0.66) domains and overall score of FACT-G (?0.74). Similarly, the total score of Part B of the HM-PRO highly correlated with three symptoms scales of EORTC QLQ-C30 (Fatigue scale = ?0.74, Nausea and Vomiting = ?0.52, Pain = ?0.59—p < 0.001) and individual symptom items (Dyspnea = 0.51, Insomnia= 0.43, Appetite loss = 0.54—p < 0.001). Conclusion The construct validity evidence presented in this research is a testimony to the HM-PRO’s ability to measure HRQoL issues which it intends to measure. This is of utmost importance when a PRO is used in routine clinical practice so that the interpretation of the scores or response to an individual item is understood by the clinicians/nurses as intended by the patients.
